Today my oldest son is 8 years old and with pizza and cake we discussed how to hack his friends tablet, star Wars vs star trek and how to hijack wifi networks when friends parents won't give password.
And he told me how to evade detection and bypass the schools filters that he figured out alone.
I feel so damn proud.11
At the airport.
Security: Please put all your electronics in the bin, including your watch.
Me: No problem
<goes through scanner>
Me: there was an Apple Watch in here and now it is gone.
Security: Oh, you lost your Apple Watch?
Me: No! I put my Apple Watch in the bin like you instructed and YOU lost my Apple Watch.
Security: It must be in the spinners.
Me: So my $500 Watch is in the spinners being run over by bins?
Security: you have to put the small things on the bottom.
Me: It was on the bottom and I did as you asked, this is entirely on you. Do not try to shift the blame to me again please.
Security: As I said...
Me: As I said, Do not try to shift the blame to me again. This is entirely your responsibility once you separate me from my electronics so you can perform security theatre. Have a nice day.
Fuck this god damn security theatre. Fuck the dumbasses they hire. Fuck your country. Fuck your god damn feeling of insecurity. Fuck Your ineffective security theatre.
Sick my fucking dick until you choke and gag you worthless pieces of shit. Homeless people the street provide more security than you incompetent, under-educated assholes. Fuck you
And yes, I have 2 fucking laptops. I have a real fucking job where I provide actual value and for that I need a work laptop. I don’t come to work in a stupid looking outfit with a chip on my shoulder looking to inconvenience people. I come to work to provide real value to someone.
Fuck you and your worthless bullshit43
Anyone looking for something interesting to do???
Step 1) understand how basic circuitry works on a bread board nothing too fancy. ( Implement NAND, AND, ADDER, SUBTRACTOR)
Step 2) learn about microprocessors and how OS works
Step 3) learn assembly
Step 4)write a basic assembler and understand how loaders and linkers works !
Step 5) write a kernel with very basic features like memory management and process management and some drivers for IO
Step 5) write an emulator for some simple systems .! ex chip-8.
Step 6) read about compiler theory and automata
Step 7) write a basic Python interpreter that compiles (not interpreter) to native assembly.
Step 8) implement TCP stack .
Step 9) learn as much as u can about complexity measurement ), data structures and algorithms using C or C++ it's very important ( familiarity with pointers and thus computer memory )
Step 10) learn any high level language of choice like Python or Ruby.
Step 11) stop debating over tabs vs spaces , emacs vs vim , angular vs vue, php vs Python , OOps vs procedular vs functional ( just know about all of them and when to use but don't fucking debate over which one is superior )..
Step 12) live happily and be healthy.30
Working with a radio chip we selected because it had built-in encryption. Cannot make the encryption work, thus in contact with the manufacturer:
"- I cannot make the encryption work, it's like the chip doesn't want to take a key.
- which key do you use?
- does it matter?
- well yes, you can't just use any key!
- why not?
- you need to get an approved key from us.
- why is that?
- so that your competitors can't read your data!
- so the way to get working keys is to get them from you?
- of course!
- keys are 256 bits. Can we potentially use all of them?
- OF COURSE NOT!
- how many can we get from you?
- one! We reserve it from your company.
- are you telling me that all units within a company will need to have the exact same encryption key?
- so anyone with our product could eavesdrop another same product?
- well yes, but it's all within your own products.
- that's not how encryption is supposed to work.
- but it's safe, your competitors cannot eavesdrop!
- I'm out of here."
(We finally found a satisfactory work-around, but i am still pissed at them)10
I recently joined the dark side - an agile consulting company (why and how is a long story). The first client I was assigned to was an international bank. The client wanted a web portal, that was at its core, just a massive web form for their users to perform data entry.
My company pitched and won the project even though they didn't have a single developer on their bench. The entire project team (including myself) was fast tracked through interviews and hired very rapidly so that they could staff the project (a fact I found out months later).
Although I had ~8 years of systems programming experience, my entire web development experience amounted to 12 weeks (a part time web dev course) just before I got hired.
I introduce to you, my team ...
Scrum Master. 12 years experience on paper.
Rote memorised the agile manifesto and scrum textbooks. He constantly went “We should do X instead of (practical thing) Y, because X is the agile way.” Easily pressured by the client to include ridiculous (real time chat in a form filling webpage), and sometimes near impossible features (undo at the keystroke level). He would just nag at the devs until someone mumbled ‘yes' just so that he would stfu and go away.
UX Designer. 3 years experience on paper ... as business analyst.
Zero professional experience in UX. Can’t use design tools like AI / photoshop. All he has is 10 weeks of UX bootcamp and a massive chip on his shoulder. The client wanted a web form, he designed a monstrosity that included several custom components that just HAD to be put in, because UX. When we asked for clarification the reply was a usually condescending “you guys don’t understand UX, just do <insert unhandled edge case>, this is intended."
Developer - PHD in his first job.
Invents programming puzzles to solve where there are none. The user story asked for a upload file button. He implemented a queue system that made use of custom metadata to detect file extensions, file size, and other attributes, so that he could determine which file to synchronously upload first.
Developer - Bootlicker. 5 years experience on paper.
He tried to ingratiate himself with the management from day 1. He also writes code I would fire interns and fail students for. His very first PR corrupted the database. The most recent one didn’t even compile.
Developer - Millennial fratboy with a business degree. 8 years experience on paper.
His entire knowledge of programming amounted to a single data structures class he took on Coursera. Claims that’s all he needs. His PRs was a single 4000+ line files, of which 3500+ failed the linter, had numerous bugs / console warnings / compile warnings, and implemented 60% of functionality requested in the user story. Also forget about getting his attention whenever one of the pretty secretaries walked by. He would leap out of his seat and waltz off to flirt.
Developer - Brooding loner. 6 years experience on paper.
His code works. It runs, in exponential time. Simply ignores you when you attempt to ask.
Developer - Agile fullstack developer extraordinaire. 8 years experience on paper.
Insists on doing the absolute minimum required in the user story, because more would be a waste. Does not believe in thinking ahead for edge conditions because it isn’t in the story. Every single PR is a hack around existing code. Sometimes he hacks a hack that was initially hacked by him. No one understands the components he maintains.
Developer - Team lead. 10 years of programming experience on paper.
Writes spaghetti code with if/else blocks nested 6 levels deep. When asked "how does this work ?”, the answer “I don’t know the details, but hey it works!”. Assigned as the team lead as he had the most experience on paper. Tries organise technical discussions during which he speaks absolute gibberish that either make no sense, or are complete misunderstandings of how our system actually works.
The last 2 guys are actually highly regarded by my company and are several pay grades above me. The rest were hired because my company was desperate to staff the project.
There are a 3 more guys I didn’t mention. The 4 of us literally carried the project. The codebase is ugly as hell because the others merge in each others crap. We have no unit tests, and It’s near impossible to start because of the quality of the code. But this junk works, and was deployed to production. Today is it actually hailed as a success story.
All these 3 guys have quit. 2 of them quit without a job. 1 found a new and better gig.
I’m still here because I need the money. There’s a tsunami of trash code waiting to fail in production, and I’m the only one left holding the fort.
Why am I surrounded by morons?
Why are these retards paid more than me?
Why are they so proud when all they produce is trash?
How on earth are they still hired?
And yeah, FML.7
Me: Fix this for me and I'll send you a cookie.
(5 mins later)
Collegue: Done, give me cookie.
Me: send MUIDB4T.txt ..... Long cookie file on Skype.
( Munches chocolate chip cookie)
(Collegue stares in disbelief....)
Me: hey I Even gave you a big one.
( Passes cookie jar )1
Fucking printers are made by satan himself.
My printer apparently needs cyan, yellow and magenta for printing grayscale.
So suddenly my colours are empty
Bullshit but whatever, I used ducktape to tape of the little glas place where it checks inkt levels.
My printer thinks they are full and prints again. Booyah.
About 200 pages further it says they are empty again.
BULL FUCKING SHIT
The satan spawn that made my printer must have made the cartridges with a chip that has a maximum of pages. So even if the cartridge is FULL, the chip says its empty and so the printer thinks that as well
If i find the demon spawn that programmed the printers, I will make you program in brainfuck or whitespace for the rest of your life!!!!!!9
A group of Security researchers has officially fucked hardware-level Intel botnet officially branded as "Intel Management Engine" they did so by gathering it all the autism they were able to get from StackOverflow mods... though they officially call it a Buffer Overflow.
On Wednesday, in a presentation at Black Hat Europe, Positive Technologies security researchers Mark Ermolov and Maxim Goryachy plan to explain the firmware flaws they found in Intel Management Engine 11, along with a warning that vendor patches for the vulnerability may not be enough.
Two weeks ago, the pair received thanks from Intel for working with the company to disclose the bugs responsibility. At the time, Chipzilla published 10 vulnerability notices affecting its Management Engine (ME), Server Platform Services (SPS), and Trusted Execution Engine (TXE).
The Intel Management Engine, which resides in the Platform Controller Hub, is a coprocessor that powers the company's vPro administrative features across a variety of chip families. It has its own OS, MINIX 3, a Unix-like operating system that runs at a level below the kernel of the device's main operating system.
It's a computer designed to monitor your computer. In that position, it has access to most of the processes and data on the main CPU. For admins, it can be useful for managing fleets of PCs; it's equally appealing to hackers for what Positive Technologies has dubbed "God mode."
The flaws cited by Intel could let an attacker run arbitrary code on affected hardware that wouldn't be visible to the user or the main operating system. Fears of such an attack led Chipzilla to implement an off switch, to comply with the NSA-developed IT security program called HAP.
But having identified this switch earlier this year, Ermolov and Goryachy contend it fails to protect against the bugs identified in three of the ten disclosures: CVE-2017-5705, CVE-2017-5706, and CVE-2017-5707.
The duo say they found a locally exploitable stack buffer overflow that allows the execution of unsigned code on any device with Intel ME 11, even if the device is turned off or protected by security software.
For more of the complete story go here:
I post mostly daily news, commentaries and such on my site for anyone that wish to drop by there21

Well, I've got a separate email address from my domain and a unique password for them. So shortening it and risking getting that account stolen by plaintext shit won't really matter, especially since I'm not adding payment details or anything.

Yeah fuck you too. I don't even have a credit card. It's quite uncommon in Europe, you know? We don't have magstripe shit that can go below 0 on ya.. well the former we still do but only for compatibility reasons. We mainly use chip technology (which leverages asymmetric cryptography, awesome!) that usually can't go much below 0 here nowadays. Debit cards, not credit cards.
Well, guess it's time to delete that account as well. So much for acquiring fucking knowledge from "experts". Guess I'll have to stick to reading wikis and doing my ducking-fu to select reliable sources, test them and acquire skills of my own. That's how I've done it for years, and that's how it's been working pretty fucking well for me. Unlike this deceptive security clusterfuck!14

Hi everyone, I'm new here but I liked the posts so I thought I'd chip in. Here's a picture of my home office.
I'm currently brushing up on SQL and Java in my internship while I await graduation at the end of the year. Java>C# IMO. C++ is my first love but nobody wants to hire for it anymore.
To everyone who's worked in Java, Eclipse or Intellij IDEA and why? (I mostly use Eclipse because the internship requires it).
I hope to have fun here, so please give me a warm welcome or a rant.23
I fucking hate Internet of Things, I think that it's a ridiculous idea to connect things, that work perfectly fine, to the internet.
The 'convenience' you get is minimalistic and most of the time non existent.
It is also often insanely insecure and expensive. The burdans it brings with it most of the time just outweigh the positive sides of it.
Now today happened something that made me hate it even more. Today was the First Lego Lego (Lego competition with ev3 robots, etc.) and one part of the tournament is to find a solution for a given problem. This year the general topic was hydro-dynamics and so the problem was how you can reduce water usage and 'save' water.
Our idea was to make reusable coffee cups and give them to the local coffee shops. One time use paper cups use take around 400ml water when produced) Basically you buy a cup once for 5 bucks and you get your coffee served in it. After drinking the coffee you return the cup to a local cafe and get a chip as pawn. When you buy your next coffee, you give them your chip and get it served in another reusable cup. The are at the moment already around 1000 cups going around the city.
Now this was our idea and we got ranked third. I am not too mad about our rank but what really drives me fucking mad is the team who ranked first.
Their idea was to make a pump (using an arduino) and a humidity sensor which you stick into a plant and the pump pumps water when the plant is too dry.
However (you probably guessed it already) they went a step further and connected it to the internet. They also made a web 'interface' for it so you can control the pump with your smartphone / computer / smartwatch / tv / whatever the fuck is connected to the internet nowadays 'thanks' to the iot 'revolution'.
So it is a pump that waters your plant when it is too dry BUT it is also connected to the internet.
WHY THE FUCK DOES THIS HAVE TO BE CONNECTED TO THE INTERNET.
"Oh look it is connected to the internet, wow awesome, oh it is also 'smart'. oh cooool. Nice I don't have to water my plants anymore"
A funny thing is that one of my friends built basically the same thing without connecting it to the internet. He built a small box with a pump and a humidity sensor that measures if the dirt is too dry and then waters the plant. It checks every few hours and the also is a small 16x2 LCD and a knob that you can turn to control how much water it should give the plant each time it waters it. He built it and I programmed it for him. Works perfectly fine and I don't see any reason why there should be any need to connect something like this to the internet.
Anyway we got ranked third, they first. I guess we should connect our coffee cups to the internet in some way ...19
Soooooo got fired on my day off!! 😁😁😁 Y am I sooo happy??? Bc the company's president sucks, and glad to be gone!!
So, I come in on my day off trying to help him with a promo for an app I was working on, and ass face come in with a chip already on his shoulders.
Him: So what are u going to show me?
Me: A walk through of the app.
Him: No, what specifically are u going to show me?(already getting upset)
Me: The whole app. Like from the login screen and everything else.
Him: No! I need to knw specifically what your going to show me! Like this button, that menu, this function!!!(boiling point)
Me: That's what I said, "the whole app"
Him: Do u want to be suspended a whole week??!!!
Me: (smiling) Yes!!
Him: You knw what, ur gonna tell me what the fuck ur gonna show me or--
Me: Gets up, grab my phone and head towards the door.
Him: If u leave, ur done!!
Me: Dnt care. (Continue out the door)
Him: (yelling) That's it, ur done!
Me: Happy 😁😁😁15
Chuck Peddle Dies at 82 (December 15, 2019); His $25 Chip Helped Start the PC Age.
His Chip brought digital technology to a new breed of consumer devices and powered early Apple and Commodore computers. 6502 microprocessor; KIM-1 SBC; Commodore PET PC are the notable works.2
When your classmates are such lobotomites, that they manage to fry 11 fucking IC's within a day! And I am the one who has to find and replace all the broken stuff. FFS it says 9V right there on the board NOT 12V! No, your board should not draw 1.7AMPS! This chip is getting kinda hot. What is wrong? ONE OF YOUR FUCKING PROBES IS BRIDGING ONE OF THE PINS!
Why isnt this working correctly? You adjusted the wrong fucking potentiometer!
I know I have far more experience than most of my classmates, but man, atleast try to not break things by just thinking: "I dont know dis. (Its actually written in the docs!) So imma assume it will be fine if I do dis. It wasnt fine!"
Also IF something doesnt work, DO NOT TURN UP THE VOLTAGE ON THE CIRCUIT BECAUSE IT APPEARS TO BE THE CLOSEST POSSIBLE ERROR. Which in most cases it is not!7

Also, Apple introduced "Today at Apple" - Hundreds of sessions and workshops hosted at apple stores everywhere in the world, where you can learn about photography, coding, art and more! (Using Apple devices of course)18
So apparently someone discovered an exploit in iOS devices which would make shitloads of devices jailbreakable and it can't be updated due to the chip being read-only.
I'm not an expert on this by far but hereby a source:
Again, I'm not an expert on this but it does seem awesome that a lot of devices (if I read it correctly) are jailbreakable now (when someone developed one with this exploit)!38
!rant I guess. Its coffee on a chip. Just spend 3h making this board to be implemented in my coffee machine. Just to wake up with the smell of coffee. The board is 2.9 by 3.2 cm12
A story about an Android TVbox which decided to become an iPad
Several years ago we've bought an android tv-box.
It served me and my family well for several years.
Specs are not that important in this story, but there they are:
Amlogic quadcore 1.4HGz
This device served us well - online TV, browsing, music, file sharing and so on. But recently cheap Chinese memory deciteed to take a break and damaged ROM. Because of that device won't boot. The only option was to take it apart and "short circuit" certain legs on memory chip and make it boot from SD card and install new firmware. After such operations tv-box worked well again.
Hoverer, memory glitched again and again and this algorithm was repeated for several months.
But that is not what is this story about.
One day memory went completely crazy and there was no way to install new firmware on it. It just hanged on install. (BTW, it was official firmware for this device)
But after countless attempts it finally worked! It installed the firmware and booted into launcher and connected to WiFi!
But now comes the most interesting part.
It was not android anymore.
It decided to became an iPad.
My dad logged in to his Google account via tv-box and got mail that someboby connected from our IP via iPad (we don't have an iPad) and using safari browser! Stock browser is not safari browser.....
"Ok, nvm, crazy glitch." - we thought.
But preinstalled play marked wont launch. Because he told us, that we're trying to connect from iPad.
And Google chrome page suggested to download chrome for iPad
And everything was acting like it is an iPad.
OK, downloaded iTunes, why not??? ._.
Tried to install elixir for android via apk from flash, but then memory glitched one more time, everything went black and tv-box had damaged ROM again...
After that we decided to not torment it anymore...
That's it. Poor Android TVbox that all his life dreamed to become an iPad. Rest in peace.2
"Never fall in love with an idea. They’re whores. If the one you’re with isn’t doing the job, there’s always, always, always another." - Chip Kidd1
a U.S. company that places an order for 100,000 integrated circuits with a Japanese manufacturer. Part of the specification was the defect rate: one chip in 10,000. A few weeks later the order arrived: one large box containing thousands of ICs, and a small one containing just ten. Attached to the small box was a label that read: "These are the faulty ones."3
1. Fucking MySQL database clusters.
There's nothing fun about MySQL clusters. Sometimes they start producing deadlock errors for no apparent reason... well, there's probably a reason, but it's never a transparent easy to find reason.
What was even less fun is that those errors took down a Sentry server. When your error log server goes down through ddos from your database messages, it's time to rethink your setup.
2. Wiring up a large factory with $2 arduino clones, each with a $2 esp8266 wifi chip, with various sensors for measuring flow of chemical solutions (I wanted cheap real time monitoring as an early warning system next to periodic sampling).
The scaling issue was getting over 500 streaming wifi signals to work in a 55c moist slightly corrosive atmosphere with concrete and steel everywhere, and getting it all into a single InfluxDB instance for analysis.12
I wrote this blog post entirely on my phone through doing an SSH on my home server. Why, you ask, well because I don't have my laptop and I am hella bored. Stupid, you say, well I agree.
I just fixed a wireless driver issue on my friend's HP laptop. I had to download driver source separately and build it and install it..
Bloody RT3290.. Turns out the WiFi doesn't work by default on laptops with this chip and Ubuntu 16**
When a mobile dev says he knows phones inside out:
"Most phones come with a built-in, disabled FM radio chip, if I needed you to build an app that enables the chip and uses it, how would you do that?"
Not relevant really, but it's always fun to stump people who act stuck-up and smart. I'd never ask this question to someone who was nervous and/or humble.10
I realized this week that my CPU is almost 12 years old!
It's an AMD FX-8150 8core @3.6 (recently overclocked to 4ghz). It's still a good chip for my needs, but eep. I had no idea I bought it that long ago.
I really want to replace it, but that would require a new mobo, too. which I suppose wouldn't be a bad thing...
AMD was comparable to (and occasionally better than) Intel before, but now? Ever since they bought ATI, they've just spiraled: virtually everything they've produced has lagged behind.
However: the Ryzen seems to break this trend, so maybe there's hope yet?11
Just thought I'd share my current project: Taking an old ISA sound card I got off eBay and wiring it up to an Arduino to control its OPL3 synth from a MIDI keyboard. I have it mostly working now.
No intention to play audio samples, so I've not bothered with any of the DMA stuff - just MIDI (MPU-401 UART) and OPL3.
It has involved learning the pinout of the ISA bus connectors, figuring out which ones are actually used for this card, ignoring the standards a little (hello, amplifier chip that is wired up to the +12V line but which still happily works at +5V...)
Most of the wires going to it are for each bit of the 16-bit address and 8-bit data. Using a couple of shift registers for the address, and a universal shift register for the data. Wrote some fairly primitive ISA bus read/write code, but it was really slow. Eventually found out about SPI and re-wrote the code to use that and it became very fast. Had trouble with some timings, fixed those.
The card is an ISA Plug and Play card, meaning before I could use it I had to tell it what resources to use. Linux driver code and some reverse-engineering of the official Windows/DOS drivers got me past this stage.
Wired up IRQ 5 to an Arduino interrupt to deal with incoming MIDI data, with a routine that buffers it. Ran into trouble with the interrupt happening during I/O and needing to do some I/O inside the handler and had to set a flag to decide whether to disable/re-enable interrupts during I/O.
It looks like total chaos, but the various wires going across the breadboard are mainly to make it easier to deal with the 16-bit address and 8-bit data lines. The LEDs were initially used to check what addresses/data were being sent, but now only one of them is connected and indicates when the interrupt handler is executing.
There's still a lot to do after that though - MIDI and OPL3 are two completely different things so I had to write some code to manage the different "channels" of the OPL3 chip. I have it playing multiple notes at the same time but need to make it able to control the various settings over MIDI. Eventually I might add some physical controls to it and get a PCB made.
The fun part is, I only vaguely know what I'm doing with the electronics side of this. I didn't know what a "shift register" was before this project, nor anything about the workings of the ISA bus. I knew a bit about MIDI (both the protocol and generally how the MPU-401 UART works) along with the operation of a sound card from a driver/software perspective, but everything else is pretty new to me.
As a useful little extra, I made some "fake" components that I can build the software against on a PC, to run some tests before uploading it to the Arduino (mostly just prints out the addresses it is going to try and write to).46
Blast from the past: this 100MHz PC came into the shop today! It has a 4GB IDE drive and some unknown thicc-chip RAM. Can somebody say... *Win9x*???17
Fuck you, you motherfucking fuck. How DARE you have the capacity to sell fake fucking chips on Amazon and make me fucking waste hours of my god damn fucking nights trying to program your shitty, lazy-ass implementation of an EEPROM.
I followed the datasheet specs down to the fucking microsecond just to find that nothing would write to the chip, and then spent hours of my goddamn life trying to figure out what I was doing wrong, making myself feel like a fucking failure for not being able to write 1s and 0s to a few pins. Fuck you, fuck you with a giant horse cock with needles on the tip12
When the new iPhone has "The highest pixel density in an iPhone yet" and "Most ambitious chip ever in an iPhone", like they'd make a new iPhone with a slower processor and a worse display?8
I signed a petition on Action Network urging Congress to reject the dangerous EARN IT Act and protect our online free speech.
The Eliminating Abusive and Rampant Neglect of Interactive Technologies Act of 2019 — also known as the EARN IT Act — gives Attorney General Willliam Barr the power to demand that tech companies kill important encryption programs. That puts us all at risk of government censorship, cybersecurity breaches, and human rights abuses.
Don’t let Congress chip away at your essential freedoms online. Sign our petition now to tell your lawmakers to reject the dangerous EARN IT Act: https://actionnetwork.org/petitions...
!rant but history
I found this old micro controller: The TMS 1000 (from 1974). The specs: 100-400kHz clock speed, 4-bit architecture, 1kB ROM and 32 bytes (!) RAM. According to data sheet, you sent the program to TI and they gave you a programmed controller back - updates to the once upload program were impossible, but an external memory chip was possible.
I'm glad we have computers with more processing power and storage (and other languages than assembler) - on the other hand it enforced good debugging before deployment and and efficient code.

Ok, I’m over windows. Done with it.
I have been a long time windows, I’ve used most versions since 3.11, and have used Linux for a few years on the side (not as a daily but have needed it for work and servers) but with yesterday’s update, not only have I lost audio for the countless time again, as far as Windows is concerned there’s nothing fucking wrong with it, besides the lack of sound and all.
Drivers are reinstalled, deleted and reinstalled, redownloaded from manufacturer, different drivers installed.
Ran a system restore back to before the update and just dropped the hdd into another laptop (it’s identical model) and still no fucking audio (to exclude the audio chip as failing)
So fuck it, I’m spending my weekend finding a distro that will work, I’m fucking done!10
Updated linux-next again.
Got another 2 FPS boost.
AMD is optimizing the shit out of their open-source drivers. And as i see in mailing list we will get BACO on pre-VEGA GPUs. (Bus Active Chip Off) = power saving feature.
Basically means much better battery life for me HEHE.
It got conflicts with linux-next and im not in the mood to fix those just for that.
But anyways AMD is making 5.5 another great release.
Odd things that non-technically-inclined people do, say, or believe:
"Back in my day we didn't have our faces planted in cell phones!" True, but they sure did love them some magazines and newspapers.
"I don't need internet! I need that 'wee-fee'" -- from my wife's stories about one of her clients, who wanted to set up WiFi.
A restaurant owner who, in 2017 mind you, refuses to upgrade his phone above a touch-tone with a handheld receiver.
When my wife, son, and I were visiting her aunt and uncle in Florida, her uncle kept asking her help on how to configure his smart phone. She's a saleswoman and I'm a computer engineer. Not complaining, just an observation. Actually I'm glad because I can avoid a million questions that I won't ever have time for.
When someone in line at the store causes a glitch in the chip reader because they don't know how to follow directions on-screen. Then they blame "those damn computers!" during a verybquick reboot.
People who enjoy sunshine. I don't understand this obsession that non-technical people have with sunny days. Maybe if I were on a tropical beach drinking whisky all day, but I live in NYS so...
When I'm describing a computer program I put a lot of effort into, only to have the conversation derailed adter thirty seconds by an hour-long family gossip section.2
Developing something which, for real world testing, would require a smartphone with a gps chip/capability or however the fuck you call that.
I do have that but it's so goddamn hard to get a lock on my location which makes it very hard to test this IRL.
I already ranted about the elevator at home being stoooopid for opening doors on way up when you wanna go down..
But our work elevator is awesome!
I figured today that I can play with the authorisation light with the chip for the home elevator.. so from orange to green (work card) to red (home chip) to green to red... OMG!!! Awesome!!
Also the look of horror on coworker's face was priceless (work elevators have a tendency to malfunction as it is, without me playing with them)!!! xD xD xD16
Hardware hacks! Here are three which are a bit different from the usual (bodge wires on PCBs, replacing dead components by some arrangement of what was in stock, etc.). All of them have been in place for some years.
(1) I bought a beamer second-hand. It was quite cheap but the remote control was missing. The beamer had a (surprisingly even documented) serial interface, which I sadly didn't get to work at all. Solution: I disconnected the serial port circuitry internally, built a replica of the internal keypad circuitry as an external remote and attached it via the now free serial connector. I now have a cable remote attached by a standard DB-9 cable hanging from the ceiling, and it's quite convenient actually.
(2) I was repairing an old scope (HP 180 series I think) and just when I was finished and started putting it all back together I smashed a ceramic trimmer capacitor. Looking at the circuit diagram it was actually a quite important part. All the trimmer capacitors I had were either physically or capacitance-wise too large to fit. Solution: Desolder the broken part and solder a piece of insulated wire to each terminal. Twist the wires until the capacitance is right, and you're done.
(3) When building my first backup server, I needed 5 volts for the Banana Pi. The result was the attached step down based on a MCP16322 (which is the 3x3 mm chip floating on top of the inductor). This 3D circuit is now kind of hanging around there. As it had always worked reliably, there hasn't been the need to replace it.6
That's it. That's all I have for my home server setup. I don't even know why we have that sticky red thing, but today it came handy. And now I can SSH anytime I want, it's never going get shutdown 😂2
I just had my cell phone cloned yesterday. End of the day, my phone lost signal suddenly. I thought it was a problem with my chip, so I decided to check that on a store and buy a new one next day.
Today, after I recover my chip and number, I started to see the mess. Someone used my number to send message to all my contacts on whatsapp, asking for money. Also, I had some contact info changed on the bank broker, which is really serious. I do not know what else is compromised, and I'm truly worried about it.
Someone has some good tips for improving security while using cellphones?29
So I got a couple of C.H.I.P. single-board computers a good while back because Raspberry Pi Zero was always out of stock.
I named them pringles, the smooth and synthetic one with a GUI, and ruffles, the sturdier and rugged one with a headless OS.
...They still lack a definitive purpose in life.4
I just wanted to show what i built.
Devrant meet projector clock.
It uses atmega and one generic 7x5 LED matrix and some rtc chip.
It projects current time on the wall opposite in scroll manner.
I also want to add internet connectivity to it next. So as to show reminders and slack notifications. Work is on for that thing.
(If you want to build one here is the code
->buying fake arduino from ebay.
->have to install separate drivers, because the manufacturer uses a cheap usb to serial chip.
-> driver page is all in chineese, only the download button is in english
-> installed the driver(at this point there was no going back)
-> instand kereal panic
Arduino + Bluetooth + L293D + car Chacis and 4 DC motors.
Finaly finished my second bot/Drone.
Actually finished it yesterday but had lots of problems with hardware bugs (learned so fucking much in a day).
Tought I fucked two unos with bad soldering... No they are fine, just won't turn on in the circuit that was already working (was fine running the code).
Redone everything from scratch with a arduino uno, it's perfect now.
Funniest part is how I got my hands on a 50€ car kit for almost free... So some Chinese store sended this kit instead of some cheap stuff. Saved another arduino with the chip rack (that one that you can trade the atmega chip), I'll save it to program single chips. Plus a h bridge and lot lot more cool stuff.
Used only the Chacis.
Next: esp8266 and camera... And maby a gun? Would be cool34
When you're supposed to make a pcb for this SMD component, but when you etch you realize it's the wrong footprint.
Ended up soldering enamel wire tomthe chip.
hope it works4
Fuck the brains of circular dependency.
On a fresh install of OS X on my hackintosh.
1) Let me install HomeBrew
2) I need Command Line Tools to install HomeBrew
3) Xcode dmg is on my Android. Opens Android File Transfer tool.
4) Error: File is larger than 4GB. Need to use adb.
5) Need to install android-platform-tools, which contains adb.
6) android-platform-tools is available in brew. Goto 1).
Note: Networking is limited to tethering mobile data as Wifi chip hasn't arrived yet.4
Why am I such an average ?
It's just a sad realisation. Nobody cares but I wanna send this out there, just to write thoughts.. I am 18 in 3rd year of high school (grammar school so nothing IT related, basically waste of time) and in IT I'm all self taught but I feel like I could be better if I just didn't [something]..
I feel like I wanna learn so many things but when I look at you, it seems like a common problem in the IT sphere so hey, average guy joining the club.
I also feel dumb when programming. I didn't manage to learn C++ in it's entirety because to really accomplish something, you've got so many ways to do it and finding the best one requires deep understanding of the tools you've got at your disposal with the language and I feel like I'm not capable of this(self learn, in school/Uni that's different story).. But many (most) of you are. I've tried many coding challenges and when I got it working, I just saw how someone did it in one line just by layering functions that I've never heard of..
Also, we've got kinda specific national competition here in many fields including IT for high schools.. And the winners always do sometimes like "AI driven Life simulation" or "Self flying drone made from ATMega from scratch with 3D simulation in C# to it" or "Game engine" or whatever shit and it's always from grammar schools and never IT related schools.. They are like me. Maybe someone helped them, I don't know, but they are just so far away from me while I'm here struggling to get the basic level of math for any kind of machine learning..
Yeah I've written Neural Network from scratch in C but meh, honestly it's pretty basic stuff .. I'd rather understand derivatives which we're going to learn next year and I'm too lazy to learn it from khan academy because I always learn something else.. Like processing (actually codetrain started teaching tensorflow so that might be the light for me...) Or VHDL (guys you can create your own chip / CPU from scratch and it's not even hard and OMFG it's so fucking cool , full adder done yay) or RPi or commodore 64 assembly or game development with Godot and just meh..
I mean, this sounds exactly like not knowing what to do and doing nothing in the end. That was me like 6-12 months ago. Now I'm managing to pick 2-3 things and focus them and actually feel the progress.
But I lost track of the original point.. I didn't do anything special, every time I'm programming something, everyone does it better and I feel dumb. I will probably never do anything special, everyone around says "He's still learning he's genius" but they have no idea.
I mean, have you seen one of the newest videos on Google's YouTube channel (I openly hate them, but I will keep that away for now), something like "Sarah story" ? It's about girl that apparently didn't care about IT but self learned tensorflow on high school. I think it may be bullshit (like ALL of their videos ) but it's probably just fancied, not complete lie.
And again, here I am. I now C but I'm incapable of learning to program good which most of you did and are now doing for living. I'm incapable to do anything cool, just understanding what everybody else did and replicating it. I'm incapable of being clever.
Sorry, just misusing devrant to vent a bit17
Got a gift from my friend. It was from an Indiegogo project. It worked fantastically until it has broken recently.
Although 1 year warranty was promised according to the site, the fact that it's from Indiegogo means that's non existence (I'd say if you actually receive the thing, you're very lucky). So I disassembled it and had a look.
Now I'm thinking maybe I just need to hack my way in to find out what that blown chip is and if I can replace it.
I am also disgusted by the Chinese printed on the IC...14
PSA: Respect open source contributors and maintainers. I'm not saying "please."
If you found a nasty bug, demonstrate the bug and write down everything you know and did in an organized way. Don't just say "this is broken" and expect people to pay attention. You'd be lucky if someone even takes the time to ask a follow-up question.
If you want a new feature, pose the idea and make a case for the benefits it gives everyone. No one is going to keep doing free work for just you.
And if you don't like the design of the software you found valuable enough to USE, then don't complain without being ready to work. Don't just bitch about code style or your opinion of what's over-engineered, even if you are right. If your free beer isn't cold enough, either chip in an implementation for a cooler or march your ungrateful ass to the next episode of the shitty MTV reality show that is your life.
In fact, if you know how to code, put up a PR for any of the above cases BEFORE asking for someone's time.
So much of the world runs on open source and the people behind the projects rarely get the credit they deserve. Treat them like the angels they are.
(Unless they are dicks for no reason. Then this is more of a case-by-case.)2
FFUUUuucccckkk me sideways. So I decided to look into USB type-c's power delivery and alt modes. Cause I kinda want to make an adapter card to run my displays over a single cable. TLDR of the rest: USB-C has some huge capabilities which noone is interested in using since its way to complex to handle for what its worth in the end.
Now PD alone is kinda ok to deal with since a lot of powerbanks use it and some hobby guys documented how to work with it. I find it really odd thou that you NEED to use a dedicated IC for using the configuration chanel to negotiate how much power you can draw. Why the USB standard didnt use some simple 5V low speed signalling? Also the standard says that you only have to implement 5v 0.6A with every other power level being optional. (This is also true for cables. Most manufacturers use only the USB 2.0 standard for them and brag about how fast type-C is. ლ(ಠ益ಠლ) )
Now to the alt modes. These motherfuckers are a real shitshow to deal with. First you need a Mux to deal with USB-C's two way insertion, so your signals wont get flipped. Next thing is that you have four lanes at your disposal in alt mode. Which you can either use for four Display Port Lanes or two DP lanes and two USB 3.0 lanes. (You always get USB 2.0) Now you may think that there would be one simple chip to do it all? Nope you need atleast two at the price of 6$ each. One for PD and one for Alt modes. Both are very hard to solder (QFN, 0.5 mm pitch 40+ pins) TI ended up being the only one with a decent offering of IC's that do what I need. As for working with them, you would think that you just slap a simple MCU on there that communicates over I2C or SPI to configure the chips? Nope! You program the chips memory from which it configures itsself. And the programming is done with some TI tool which gives me no idea as to how you can handle everything whith no control logic behind it.
Looking into alternative IC's leaves me with cypress semi. And their documentation is basically a total mess. I wanna know what that chip is good for and what I need to do to make it work. I dont care about technical details mixed with marketing jargon nobody understands. And I really despise that I have to register just to download a datasheet. Especially since there is no info about it on the main page.
And this whole rant hasnt even touched the topic that USB-C only uses DP and nothing else. So you better hope that you have DP++ so you can use a passive conversion.
This was my Ted Talk about USB-C. Some info in it may be subject to my stupidity and errors as it currently is 02:15 in the morning and I need some sleep.14
Ideas for a strong password:
- a regex matching my laptop's LAN IP address
- a sed command to enable X11 forwarding in sshd_config
- a shell oneliner extracting all the IP addresses from ifconfig / ip a sh
- an awk command to print processes in D state
Damn of we can't trust anymore, even banks went under the attack!6
One job I picked up was for an IoT Start Up. It was quite interesting work, reporting to the technical director, who was an electronics engineer, who was designing the hardware himself, they had a couple of firmware guys already, and just needed someone to take care of the software.
So they said they needed something in Azure that they could stream their data to and provide analytics for their clients. It had to be Azure, and it had to be Azure Native, and was to be Multi-client, as they had a deal with Microsoft to showcase how well Azure works in the IoT space at an exhibition/conference in 3 months time.
So I worked flat out for 3 months, on a whole variety of technology, from C++ to get the radio packets from their IoT chip, Python to run on the hub to take the data from the C++ and stream it to the cloud, Azure IoT Hubs in every continent to receive the data and store it an a Cosmos DB, and then Power BI analytics wrapped up in an Angular front end that the clients could log into.
Got it finished 2 days before the show, and they were so pleased I got flown business class to Singapore to be on the stand and talk to customers.
The first sign of trouble was when we arrived at the show to find we just had one of those little circular tables with two stools in the middle of the floor, about two feet across and no power.
No problem, I was able to sort that, swapping laptops in and out.
Microsoft were really happy with what we had, and couldn't believe I had thrown it all together in 3 months.
We picked up a potential customer for the system, a major Asian Telecoms company.
Then when we got home, the CEO swooped in. I had never met this guy before. Imagine one of the VC guys from Silicon Valley, or the CEO from the IT Crowd. You get the picture. Could talk the hind leg of a donkey, and real street smart, but no brains. He insisted on "taking it from here" and flew alone to strike the deal with the customer. Came back with an MOU in his pocket and said to me, their guys will be in touch with you.
Then I got a call. Can you send us the source code and tell us how what servers we have to run this on?
Um, its cloud native.
No, we can't use a cloud it has to be on our servers - your CEO told us that was no problem..
He hadn't even taken the trouble to find out what it was we had built, and what he was selling.1
The moment when NVIDIA realise they just compared there too of the line laptop chip to what is essentially a mid range device... I mean... The math checks out but you know... You compare nano to vim and you know what that looks like13
One of my employees just gave me a panchito(basically a fried tortilla chip with cheese, avocado and meat) and went away. He legit bought it from the cafeteria, walked all the way to the office to give me one, and left to eat it back at the cafeteria 🤣🤣🤣 bless him.
This is a follow up to my previous rant where I complained about Lenovo firmware update failing and bricking a relative’s computer.
We bought a chip programmer, got the bios from some forum and the thing fucking worked. I’m actually surprised it did, I’m not used to doing shit like this. I was pretty fucking scared of burning something.
The programmer also came with a clamp so we could hook it to the chip without desoldering it. Thank god.
I’m terribly depressed so good timing with that I guess.1
Look... Linux... I fucking love you and I especially love elementary OS but please... Why is it so fucking difficult to be able to play a youtube video in fullscreen or have a browser go fullscreen without the window locking up -.-
(Feel free to chip any advice, it's super annoying because it works perfectly on my primary monitor but not any other)12
*places an order on OnePlus' website for that OP6T*
Alright, payment.. with my bpaid card that I ranted about earlier, because apparently the fuckers accept only credit cards. External payment portal, card's got a chip.. well that's gotta be the same payment process as the usual Bancontact purchases then, right? Where you plug your card into your Digipass card reader, get a start code from the website, type that in, amount to be paid, PIN code, and then it spits out another code that you give to the payment portal.
Except it isn't. That CVC thing is apparently the only thing that stands between you using your card and someone else doing the same with your card information. Not even the card itself! Why the FUCK do we even have PIN codes then?! This is even worse than the magstripe and the skimming issues related to it (the magstripe essentially just blurts out your card information to whatever wants to have it, so demagnetize it and don't use the payment terminals who refuse your card on grounds of not being able to read the magstripe afterwards. Your chip should be responsible for that.. but I digress). Credit cards with chips in it that aren't even used. That's what you Americans use? Seriously?!
At this rate, you can keep your fucking credit cards.10
Well, I suppose there's no rules against talking about a non-tech company situation.
Before I made it into my career as a developer, I wrote code as a self-learned hobby programmer. I had a job though, which was selling chips. No, not ICs... potato chips. Funny enough, I made a killing doing it.
Anyway, this isn't about me. It's about the guy who quit shortly after I showed up. You see, we all had company trucks and most of us parked them at the warehouse and commuted in our own vehicles. We'd load the trucks up with product and lock them up in the yard for the next day.
It used to be that there was an option to take the truck home, but after this gentleman, that was reserved for special instances.
That would be due to the fact that the guy played "hide the chip truck" and called up to quit his job, forcing my former boss to hunt around an entire city to find the damn thing.
I've found it isn't so different in software, except when people quit, it's more like "hide the actual deployed branch you didn't commit".
Very few general embedded systems books exist, most are specific to chip, or architecture. Very few cover overall ideas, and concepts that are common across ALL embedded systems regardless of architecture and things you must keep in mind while designing software for them.
I think this a a good book. As a primer for deep diving into embedded systems design philosophy19
This is legit bad news.
The Big Hack: How China Used a Tiny Chip to Infiltrate U.S. Companies
The attack by Chinese spies reached almost 30 U.S. companies, including Amazon and Apple, by compromising America’s technology supply chain, according to extensive interviews with government and corporate sources.
Personal project: I design and build single-board computers with old processors like Z80, 6502 etc when I'm not being too lazy. A few run CP/M. One that's been more interesting in terms of digging deeper has been an 80C188, for which I've written a BIOS (despite the chip's built-in peripherals and interrupts being at non-standard addresses) mostly in C, which it can use to boot DOS from an image file on an SD card (bit-banged off the UART chip with FatFs). (Yes it's slow, but so is a 5.25" floppy.)
Work: My first project at my current job. Not particularly exciting compared to some stuff on here, but it got me into making useful contributions to the open-source CRM we used at the time. Was building a basic extension to deal with duplicated organisation names. So learned CiviCRM fairly deeply, a bit of Drupal, a bit of PHP. It's a shame we don't use that system any more, the community was cool.7

Oh for crying out loud. Master/Slave has been the defacto way to describe dependent interactions between electronics since the birth of the silicon chip. Even IDE used to implement it as a standard for running multiple devices over a single cable. Just because a handful of fresh faced 18 year old kids think the world owes them a soap box and a rock to hang themselves over, it does not mean the world has to bend to this oversaturated retribution complex that seems to be affecting every college student lately. Grow the fuck up.5

(I just posted this in a shorter form as a comment but wanted to write it as a post too)
TL;DR, smarts are important, but so is how you work.
My first 'real' job was a lucky break in the .com era working tech support. This was pretty high end / professional / well respected and really well paid work.
I've never been a super fast learner, I was HORRIBLE in school. I was not a good student until I was ~40 (and then I loved it, but no longer have the time :( )
At work I really felt like so many folks around me did a better job / knew more than me. And straight up I know that was true. I was competent, but I was not the best by far.
However .... when things got ugly, I got assigned to the big cases. Particularly when I transferred to a group that dealt with some fancy smancy networking equipment.
The reason I was assigned? Engineering (another department) asked I be assigned. Even when it would take me a while to pickup the case and catch up on what was going on, they wanted the super smart tech support guys off the case, and me on it.
At first this was a bit perplexing as this engineering team were some ultra smart guys, custom chip designers, great education, and guys you could almost see were running a mental simulation of the chip as you described what you observed on the network...
What was also amusing was how ego-less these guys seemed to be (I don't pretend to know if they really were). I knew for a fact that recruiting teams tried to recruit some of these guys for years from other companies before they'd jump ship from one company to the next ... and yet when I met them in person it was like some random meeting on the street (there's a whole other story there that I wish I understood more about Indian Americans (many of them) and American engineers treat status / behave).
I eventually figured out that the reason I was assigned / requested was simple:
1. Support management couldn't refuse, in fact several valley managers very much didn't like me / did not want to give me those cases .... but nobody could refuse the almighty ASIC engineers. No joke, ASIC engineers requests were all but handed down on stone tablets and smote any idols you might have.
2. The engineers trusted me. It was that simple.
They liked to read my notes before going into a meeting / high pressure conference call. I could tell from talking to them on the phone (I was remote) if their mental model was seizing up, or if they just wanted more data, and we could have quick and effective conversations before meetings ;)
I always qualified my answers. If I didn't know I said so (this was HUGE) and I would go find out. In fact my notes often included a list of unknowns (I knew they'd ask), and a list of questions I had sent to / pending for the customer.
The super smart tech support guys, they had egos, didn't want to say they didn't know, and they'd send eng down the rabbit hole. Truth be told most of what the smarter than me tech support guy's knew was memorization. I don't want to sound like I'm knocking that because for the most part memorization would quickly solve a good chunk of tech support calls for sure... no question those guys solved problems. I wish I was able to memorize like those guys.
But memorization did NOT help anyone solve off the wall bugs, sort of emergent behavior, recognize patterns (network traffic and bugs all have patterns / smells). Memorization also wouldn't lead you to the right path to finding ANYTHING new / new methods to find things that you don't anticipate.
In fact relying on memorization like some support folks did meant that they often assumed that if bit 1 was on... they couldn't imagine what would happen if that didn't work, even if they saw a problem where ... bro obviously bit 1 is on but that thing ain't happening, that means A, B, C.
Being careful, asking questions, making lists of what you know / don't know, iterating LOGICALLY (for the love of god change one thing at a time). That's how you solved big problems I found.
Sometimes your skills aren't super smarts, super flashy code, sometimes, knowing every method off the top of your head, sometimes you can excel just being more careful, thinking different.5
My grandmother recently died and me and my brother were wondering what was to happen to her 10+ year PC (Dell optiplex 760). I could find a use for the monitor and my brother wanted to use it as a server. We asked around at the family and everyone seemed ok with that except for one guy..
Apparently the PC is still in "prime condition" running Windows 7 after an upgrade from Vista. It has 'a graphics chip or something like that' and is better than any laptop on the market right now. (I actually had my HP zBook 15 g3 with me). He claimed it wasn't some old worthless piece of junk and most family members would probably be interested in this machine.
I didn't try to argue because I realized he was not at all knowledgeable about technology and I didn't want to be disrespectful.3
I just got my first debit card, I'm super excited about it, but there is something inside me wanting to use an NFC writer app to write to the cards internal NFC chip
I am a scientist. A computer scientist.
I am an engineer. A software engineer.
My lack of a formal college degree does not negate these facts.
It does, however, contribute to the chip on my shoulder.2
I have to share this. These guys are unbelievable! They claim they will build this console that will run a modded Debian Linux. Ok so far...
But then they say that it will run Windows games...
Wine you may think?!
They say they will make a 'revolutionary' motherboard, that will RUN WINDOWS GAMES (?!?!?), WITHOUT WINDOWS!!!! And they will do this by putting a fucking FPGA chip on the board!!! That will INTERPRET .EXE FILES (IN HARDWARE LEVEL!!!)
They must be gods to run an .exe file using nothing but (V)HDL without the shared libraries and at hardware level!
FUCK! I'M MAD!!!
Scammers gonna scam!
P.S.: FPGA - https://en.m.wikipedia.org/wiki/...7
As a guy with a Intel 6800K I now really feel robbed of my money by Intel.
For over 10 years they knew of the heavy design flaw and put it through.
The ironic thing is, that every country will set up a penalty for Intel, but the Customers with the CPU's wont even see a buck.
It sucks that I have up to 30% less CPU Power after next weeks patch.
I will banish Intel now forever!! You should never come again in my Business!!!
Even my newly ordered Tablet with a Intel chip will suck d*ck now...9
I'm on the hunt for new and exciting languages!
I'll state the ones I already know:
I've also learnt some styling languages:
Html, CSS, Markup and Markdown.
Some misc languages too: Regex and a runny bit of the Wolfram Language.
Also I'm kind of limited to Windows, Linux and Android, as I do not own any Apple hardware except I have access to an old iPad, so are languages like Swift still good?
My image of dream career through different times of my life:
- frontend specs prodigy, css enlightenment, a member of w3c or a similar committee
- indie hacker and entrepreneur, leader of a startup community
- architecture prodigy, expert in scalability
- transsexual evangelist, popular article writer and a rockstar
- hardware engineer: Linux, C, chip and dale’s Gadget-like girlfriends, xkcd, latex, assembly, buying a radio station and a telescope
- scientist like NickyBones, papers, data, more data
- art expert
Though achieving one of this would take the entire life, I had a chance to grasp all of this. WHY does they feel so incompatible? Why do I have to choose?
Why do I feel so sad? Why do I feel like I haven’t achieved anything even though I objectively achieved what I dreamed of like five years ago?
Is it true that it’s in my nature to always seek an environment to feel like a junior in? Is feeling like a junior only pleasant to me because it reminds me of old times when I wasn’t actually this mentally ill and was still happy?
Why do I feel like that arduino and C shit is the equivalent of a red corvette?6
Just discovered a band named Master Boot Record. All of their albums are execution files. It's kind of metal meets chip tunes actually pretty good, if you're into that kind of thing.
Me and mainling bluetooth on my phone.
*Implement the bluetooth node*
Driver: FUCK YOU
*Replace the regulators names with proper ones according to new driver*
Driver: FUCK YOU
*Find that one regulator is wrong*
Driver: FUCK YOU
*Add max frequency to not go over that limit*
Driver: FUCK YOU
And this my friends is kernel development in short.
Driver cant read the data from the chip because its offline. And i have no clue why.
And it has no way of telling me why.
Cause it doesnt know.7
Most successful project at work: NodeJS utility for storing loads of measurements from an application running on various other systems and providing fast ways of getting at that data. No DB, just CSV files broken into time periods. Also has a search function written in C that can very quickly find all user sessions matching the criteria. It's not perfect, but it does the job pretty well and I can tweak the storage engine as much as needed for our use case since its all custom written.
Outside of work: Incomplete right now but I soldered some wires onto an old sound card and managed to get an Arduino to configure it and play some notes on its FM synthesis chip. Still quite a newbie to electronics so this was quite an achievement for me personally.
So it's required by law to chip and register your dog. I just got a puppy so I had to change the owner of the dog from the kennel to me. And the only thing I needed was my chipvalue and the registration number.
So all I have to do is scan the dog and try the registration numbers and then I can change the owner. Like wtf. And it does not even send a confirmation email. I checked by changing owner and email again.
My registration number is only in the 600K so other registered pets should be easy enough to bruteforce.
Or am I missing something?7
Oh ffs, just fucking inject a chip into my finger already for authentication purposes, you can track my every fucking move if you so wish. When a web page like twitch uses 2FA it boggles my mind because its a page where you're watching some fucking videos.
"hey there, so out of the blue, we send you a code to your email, we won't tell you which so good luck. Also, you cannot copy paste this code because we did that fucking thing where each character has its own textbox"
Of course, this is only because we are dumb enough to reuse shitty passwords. THIS IS WHY WE CAN'T HAVE NICE THINGS.34
The feature was to parse a set of fairly complex xml files following a legacy schema. Problem was, the way this was done previously did not conform to the schema so it was a guideline at best, which over the course of many years snowballed into an anarchy where clients would send in whatever and it was continuously updated per case as needed. They wanted to start enforcing their new schema while phasing out the old method.
The good news is that parsing and serialization is very testable, so I rounded up what I could find of example files and got to work. Around the same time I asked our client if they had any more examples of typical cases we need to deal with, and sure enough a couple of days later I receive a zip with hundreds of files. They also point out that I should just disregard the entire old set since they decided to outright cut support for it after all if it makes things simpler. Nice.
I finish the feature in a decent amount of time. All my local tests pass, and the CD tests pass when I push my branches. Once we push to our QA env though and the integration tests run, we get a pass rate of less than 10%.
I spend a couple of days trying to figure out what's going on, and eventually narrow it down to some wires being crossed with the new vs. old xml formats. I'm at a loss. I keep trying to chip away at it until I'm left with a minimal example, and I have one of those lean-back moments where you're just "I don't get it". My tests pass locally, but in the QA environment they fail on the same files.
We're now 3 people around my workstation including the system architect, and I'm demonstrating to the others how baffling and black magic this is. I postulate that maybe something is cached in my local environment and it's not actually testing the new files. I even deleted the old ones.
"Are you sure you deleted the right files?"
"Duh of course -- but let me check..."1
I'm in a small company so they don't have a big budget.
The previous I.T guy went full retard and decided that it would be a great idea to buy a shitty 200$ laptop with a soldered eMMc hard drive for accounting.
Since they NEVER use the cloud and just pass around excel files, the files aren't really saved anywhere but on the USBs and the computer.
Guess what ? The motherboard fucking fried and almost 6 MONTHS of accounting work was lost. Out of warranty of course, not that it would help since the eMMc chip is also fucked.
That's what you get for trying to cheap out on hardware and not choosing the right stuff.4
Wow man. Can the day get any worse
Mother fucker creator of Android. Now I'm A long time android user, but
Android+Snapdragon 6XX chip+Moto= worst combo ever. Damn you creators, may You be deepfucked by a mad bison in heat. Cocksuckers.
The heat my Moto X play generates, I could make an omelette on top of it. And the newest feature, where you try to type, but you can't see anything happening, when 30 secs later, you suddenly start seeing the after images of all the buttons you pressed, all the text you typed. Why maybe I typed at the speed of light and android couldn't keep up. No.
NO! You dumb fuckin POS. NO. I threw my phone 20ft, broke the tempered glass. The case protected this shit. Once I can save enough, I'll either sell a kidney and get an iPhone or even better a OP5.
Nothing disgusts me more than slow hardware.12
Last rant was about games and graphics cards (admittedly not received too well), time for a rant about game development houses.. especially you EA.
So yesterday a friend of mine showed me in one of our Telegram chats that he'd modified some cheats in an old FPS game by editing these scripts (not Lua for some reason) that the game used as a.. configuration language I guess? He called the result a tank cemetery 🙃
Honestly the game looked a lot like Medal of Honor to stoned me at the time, so I figured, well why not fire up that old nx7010 I had laying around for so long, get a new Debian installation on that and rip the Medal of Honor: Allied Assault war chest that I still had, and play it on one of my more modern laptops? Those CD's are now very old anyway, maybe time to archive those before they rot away.
So I installed Debian on it again, looked up how to rip CD's from the command line, and it seemed that dd could do it - just give /dev/cdrom as the input file, and wherever you want to store your copy as the output file. Brilliant! Except.. uh, yeah. It wasn't that easy. So after checking the CD and finding that it was still pristine, and seeing another CD in that war chest fail just the same, I tried burning and then ripping a copy of Debian onto another CD.. checksummed them and yes, it ripped just fine, bit for bit equal. So what the fuck EA, why is your game such a special snowflake that it's apparently too difficult to even spin up the drive to be copied?
So I looked around on plebbit and found this: https://reddit.com/r/DataHoarder/... - the top comment of that post shattered all my hopes for this disc to be possible to rip. Turns out that DRM schemes intentionally screw up the protocols that make up a functioning disc, and detecting those fuck-ups is part of the actual DRM.
"I also remember some forms of DRM will even include disc mastering errors/physical corruption on the actual disc and use those as a sort of fingerprint for the DRM. The copied ISO has to include them at the exact same place in the ISO as on the IRL disc and the ISO emulator has to emulate the disc drive read errors they cause."
So yeah. Never mind that I already own this goddamn game, and that it's allowed by law to make one copy for personal use, AND that intentionally breaking something is very shady indeed.. apparently I don't really own this game after all. So I went onto the almighty search engines, and instantly found a copy of this game for download. You know EA.. I wanted to play nice. You didn't let me. Still wondering why people do piracy now? Might take your top suits that suggested these fucked up DRM schemes another decade to figure out maybe.. even given the obvious now.
But hey I wouldn't even care that much if the medium these games are stored on wouldn't be so volatile (remember these discs are now close to 20 years old, and data rot sets in after 30 years or so). You company decided to publish these on CD. We've had cartridges in many forms before, those are pretty much indestructible and inherently near impossible to duplicate. And why would you want to? But CD is what you chose because you company were too cheap to go to China, get someone to make some plastic molds and put your board and a memory chip in that. Oh and don't even get me started on the working conditions for game devs.. EA and co, aren't you ashamed of yourselves? No wonder that people hate game development houses so much.
Yay, almost finished downloading that copy of Medal of Honor! Whatever you say EA.. I've done everything I could to do it legally. You are the ones who fucked it up.10
** this means words are muted **
I send a mail the client a Google doc with elaborate details about evaluation of an Android tablet from a Chinese manufacturer.
The client is upset, he says "You say there is no GPS chip on the tablet while the manufacturer says otherwise"
Me- "I have clearly mentioned that it has a GPS chip"
Client- Opens the Google doc, points to a sentence. Looks at me like I did something horrible.
Me - **This guys is either word blind or something else is wrong with him, the line reads 'GPS chip available'**
Me- "Look, it says 'GPS chip available'.
Client- **Blinks n blinks again** "Alright, but why did you share a Google document, why not PDF, docx"
Me-**Politely** "You can download the document in any format, look I will show you..."
Client- "It should have been in the mail itself ideally"
Me- **WTH** "We normally maintain a document for such things to keep everything organised, but if you want I will put everything in mail itself"
Client- "Hmm.. do both from next time"
Me- "Alright" **BS**
Client- "Why is the new feature taking so much time"
Me- "As planned earlier, we going to deliver it tomorrow"
Client- "Why not today??" **Gives a strange look.**
Me thinking - **Enough**
Me- "See, I am trying to integrate a smarten with a socket connection, reading it's data via exposed APIs that are hardly documented, we need faster performance so I need to implement caching, multi threading, offline handling, multiple processes to avoid memory fluctuations, sync adapter to sync data...."
Client- "Ok ok ok, it's fine if you give working build tomorrow"
Me- "Ok, fine"
One of my hobbies is to repair stuff.
In front of me is a Xiaomi Notebook air 13.3", a very nicely build device.
But it's driving me nuts, the screen is completely glued onto the front glass.
How the fuck am I supposed to exchange that display with a new one?
The main problem with those devices seems to be the display-cable in the hinge.
It might short 3.3V to 19V backlight, killing the display, the hdmi controller and the audio-chip.
2 ez fixes so far, but that fucken display.
And the absolute worst is that there are 0 official replacement parts available for any of the Xiaomi notebook's.
You think one day your dog could be a wireless adapter. Nowadays dog are getting microchips, as sick as it sounds I wonder if you can ad a wireless chip card on a dogs microchip.5
TL;DR: intel stripped the hosted network function from the drivers for my wifi chip. Older versions can still so it
Every month I travel by bandbus to neighbouring countries for a show.
This usually takes 7+ hours.
So i have my laptop with me and if my brother is along as well, we game in the bus.
Using a cable for internet connection isnt handy, since we sit on opposite sides of the bus. So i looked up if I can use a hosted wifi network for this.
We both checked out our drivers and both said no hosted network support.
And some posts on the internet said that customer support told them that the chip can't do it
But thats weird. My laptop is high end. So I searched a little only to find out that I can do a hosted wifi network if I DOWNGRADE my drivers.....
Fuck you intel. Fuck you hard for stripping that function from the drivers1
Something weird, my old contactless visa came apart and i took the contactless antenna and noticed that it doesnt connect to the chip on card in any way but has three stripes that perfecttly overlay the three sectors of magnetic stripe of the card.
Does this model work by actually reading the magnetic stripe when paying contactless?????12
So this Just happened, we were in a Meeting when Manager Tells us about "Time Management" and asked us Whatsapp we could Code for him,
I suggested that we use those Chips to track us and the employees, because we always use them to unlock Doors and Stuff,
Another Suggestion from another Person was:
To use Paper...
I was Like "WTF dude Pen and Paper? Didn't you listen?"
We now use Pen and Paper to weite our working Times Down...1
Yesterday I bought a book. I did not know about it. So I read the first few pages before purchasing it. I did not look for the review online. I paid by card - not through my phone or contactless, just plain old card going into a chip and pin device.
This morning I got an advert in Facebook that I should buy the second part of the book. I know they snoop my online activity. In a weird way I kind of accepted it. I guess my question is how'd they know so much of my personal life.
I'd probably will leave Facebook today. I am sure they are watching this status as well. I hope the jackass behind this learns in my own small way I tried to stand up against their jackassery. Like everyone else here I from IT. I hope some one (or many) from this extraordinary community who is a lot more capable than I am, stands up to this invasion and make an end to this snooping.9
China used a tiny chip in a huge hack that infiltrated Apple and Amazon. The attack—denied by the companies—compromised the U.S. tech supply chain, sources say: https://www.wbca.st/PPrOcew1
Here, a full retrospective of my Apple products ownership.
iPhone SE – after Android, I was absolutely amazed by how fast it worked. No UI lags, camera works absolutely instantly no matter the light conditions, all the GPU-heavy games work butter smooth.
After camera and charging port failures on Xperia flagship and CPU literally melting through screen rendering it unusable on Meizu, it was enough to make me interested in Apple products.
When I was using Meizu, I actually got a twitching eye which was triggered by UI lags. After two months of using iPhone, I noticed that something was missing – my eye wasn't twitching anymore.
iPhone actually cured me.
MacBook 12 – a 900 grams laptop with passive-cooled mobile CPU running many Chrome tabs, heavy Webpack HMR build, VSCode and Slack just fine. Yes, you can't play games, but I don't even require it from a laptop this tiny.
Butterfly keyboard that internet hates so much actually increased my typing speed and comfort compared to MX Red mechanical keyboard, and ForceTouch trackpad made me forget about mouse. I learned how to disassemble the Butterfly keyboard if I ever need this but the keyboard never failed.
I use this laptop to this day and it still even smells like the day one, a beautiful smell of a new Apple product.
iPhone X – got it because of the camera, stayed for great battery life and amazing OLED display. I use telephoto lens exclusively and it made me lay off my Canon DSLR with Helios lens which stays on my bookshelf covered in dust to this day.
True black of OLED display which is undistinguishable from the screen bezel is stunning. To this day, battery surely works for one and a half days and I watch youtube really often.
I sometimes struggled to unlock iPhone SE with wet fingers, but with FaceID, as soon as I look at the screen the phone is unlocked. Works perfect every time, never had an issue with this.
Stainless steel body feels premium compared to aluminum. Stereo sound is a major selling point if you're like watching videos and playing games on your phone. Overall amazing product and a huge improvement over SE.
Apple Watch series 4 – really comfortable fit. Nice battery life, once I forgot about it for like ten days during lockdown and it was still working, even though on power reserve mode. Really reliable in terms of battery life and liquid protection. Very satisfying Taptic Engine crown clicks. I run every day and Apple watch always measure my heart rate correctly, and the running app is well designed and a pleasure to use. Overall a nice accessory to have if you use iPhone.
Powerbeats Pro – great sound and battery life. I switched from Shure SE215 which was great, but it had wires. I listen to a lot of music so the sound quality is important for me. When I was choosing earphones I visited a store where you can listen to them all. I listened through earphones like Noble Audio Kaiser Encore and JH Audio Layla, and of course $4000 Laylas sound better than $249 bluetooth earphones, but the difference in sound doesn't justify the difference in price to me.
Powerbeats pro is the Apple H1 chip true wireless earphones with largest driver of them all which makes them sound better than AirPods Pro – it's just physics. Bass in Powerbeats is amazing, which is also true for my Shures, but Powerbeats also win in clarity.
It connects seamlessly to both my MacBook and my iPhone, and everyone in voice chats can hear me really good.
Huge case is a major throwback compared to AirPods, but the battery life of earphones themselves is so great that I just leave the case at home and only carry earphones and it works for me.
Apple Link bracelet in space black – really better than I expected. Intricate detailing, literally the steel that Rolex uses, top-notch finishing and polishing – all that for just 450 dollars. I only used it for several days now, but it already feels like a really satisfying product.
Before all that I was using Linux. It took a year for elementaryos devs to fix wifi for my laptop. Ubuntu looks and feels ugly. Pop OS felt like garbage. Manjaro was also just that – garbage. KDE Plasma – I don't even want to talk about that. A monstrocity where you accidentally click a wrong switch in the settings and your system won't boot up again. Also, PulseAudio. Struggles with proprietary drivers and software updates.
Windows? I serviced a lot of Windows PCs through my career and it never, never worked as intended. I'm no dumbass, I always managed the rights correctly and never installed sketchy apps. My latest ryzen gaming build with a lot of ram also lags somehow even in Windows 10 UI.
Before I switched, I defended Linux.
My life was a lie.
I'm sorry to everyone who I offended based on their opinion on Linux.44
My laptop charger is dead and my laptop can't work without it. So, basically I can't even look at code.
Colleague calls, says there is a problem with package.json and it requires my immediate attention as the APIs need to be deployed.
Me enters Sherlock mode, and remembers that I have a git hook which took a backup of my code every time I pushed and saved it on my headless tiny CHIP.
I get excited, and do an SSH from my phone, hoping to see the faulty code/file. But all I see is an outdated repository because I am an idiot who forgot to turn the fucking CHIP on after I shut it down for cleaning.
This is the most anti climatic ending I have been ever part of.3
Kind of dev related, during a Firefly one-shot roleplay:
GM: So you have a data chip in your pocket. Do you want to see what's on it?
Me (hesitant): ...Kinda. *wait* Okay, I put the chip into one of my computers.
GM: The data chip shows random gibberish--it's encrypted. Your engineer may know how to decrypt it.
Me: Okay. Hey, Engineer! *holds imaginary data chip out to her* Decrypt this!
Engineer: No. *pause*, *sighs* Fine. But we need to be careful.
GM: Yes, now time for technobabble...
Me: So once we decrypt this, it's probably going to look for the MAC address, so we need an air-gapped machine--a machine that's never been online before--and a TAILS LiveUSB. We'll decrypt the data chip and then destroy the computer.
Fighter: ....I actually understood that and it actually makes sense. Good job. *fist bump*1
Holy shit! I have not programmed a Teensy micro in a while. So I was looking at what they offer and saw they now have a 600Mhz version that is the same size/pinout as their 72MHz version. I am just amazed by how much micros have changed. I love the embedded wifi chips that are out there too. I guess I am going to be playing with the Teensy the next few weeks. I love playing around with embedded audio processing. Lately I have been playing with bluetooth wireless audio. So this will fit nicely. The chip has 2 AD and assorted digital audio inputs/outputs.
I dunno, I was excited and this seems like a nice new years present.3
So today (as of 5 min ago) marks a great day for my personal projects! I just got my embedded systems Flash memory driver debugging on my PC in Visual Studio, talking directly to the REAL flash chip, WITHOUT being tied to a embedded target! It's glorious. I can finally debug and write tons of tests without having to worry about the constraints of my embedded system. Ahhh. All the pieces I've needed to build this have slowly come together over weekends, and it feels so good to have this tool in my arsenal now! Great day indeed.
Ohhh my god am I furious and this one's a gem.
Also I'm gonna namespoil all of the entities in my post. If this is against rant rules I'll reframe it.
So the story starts over an year ago. Me, being in a bad place, where I couldn't do a job due to external issues, wanted to try out an internship. Thought I could pull off a 5 hour shift and then attend to my problems.
THE INTERNSHALA ARC:
I apply to a bunch of applications on Angel, Internshala and Indeed.
I was contacted by a few handful of these places. One of them was called "ARCHITECTA SOFTWARE SOLUTIONS". These guys had arranged an online aptitude test for me which I promptly took.
I looked up this company and they seemed like a pretty okay big firm from the outset but didn't have many reviews on Glassdoor and likes of such. (first red flag). Post aptitude test, I was quite sure I fucked up and wouldn't get further contact. Surprisingly, a person from the company sends me his Whatsapp number over chat and asks me to save it. The message is worded like a bulk email (Starting with Hello everyone!!) which I thought was quite odd since the interaction from these platforms has always been a person-to-person contact for me. Since Internshala showed that only around 40 people applied for the position I was quite intrigued but attributed this to my lack of exp in internship operations.
THE WHATSAPP ARC:
I was contacted by the number on WhatsApp saying that they'd be interested in moving forward and I gave them my work experience details.
The person sends me over a development assignment to complete within a few days. The assignment consists of massive scope of details. I'm talking production level concept and implementation. Asks to me implement a custom emotion detection CV model (worded as "emotion camera" lmao), generate a 3d model (specified nowhere and expects to implement a mono-ocular system for the curious) and deploy it over AWS with a website to go along with it and also host that. The website should contain a VR ("360 rotatable") view that can explore the depth-map ("not worded as depth-map") of the face. My first assumption was that they had picked this work up for outsourcing and didn't bother to chip off parts so as to create an assignment out of it (I know very optimistic).
So I shoot it at him on WhatsApp asking which parts of the assignment should I do?
Him: So, which parts CAN you do?
I thought of it as an HR thing.
Me: I could do most of it but given the time-frame of the assignment and my applied position as a web developer it is perhaps out of scope for my application.
Him: Don't worry about the assignment. You can submit when you complete the whole assignment.
I was visibly angry over the stupidity of this man.
Me: This task is a Full-Stack + CV + VR task. It will take over two months to get working. Am I supposed to work on it for that long for an assignment?
Him: Okay just do the basic functionalities like add to cart. But also try to do the camera thing before next week.
At this point I'm sure that they are having trouble handling an eager client and they're offloading work to interns. So I do only the backend and minimal frontend and submit the assignment (a 2 day job done over a weekend).
Nothing. Empty. No messages since then. I tried sending in a Whatsapp message on the application and how to proceed. Then, if I could get to know if I have been rejected. Nothing.
And all this time I can clearly see the account is active as it pushes pretentious motivational quotes over it's Whatsapp status.3
Digging though my old emails found this joke sent to me long time ago. Think that originally was posted in a 1997 issue of Computerworld. Maybe you already suffered the effect of the "Opcodes" listed here. Hope that !tl;dr

So, apparently that another kickstarted IoT chip dev team forgot to bind reset button to anything, so it is just sitting there as a fidget toy and they also messed up with usb-to-serial connection so it is working only in transmission mode. I am just sitting here with bricked chip with no adequate possibilities to unbrick it.1
I have lost now another device to planned obscolence (how is that still legal), my g3 officially took its last breath two days ago, first it was its battery dying (thousands of devices broke that way [exactly two years after buying it] and at that time there was no batteries to replace it with) - whoever was brave enough to hold onto his device for longer than the battery failure - he then faced the simcard reader breaking and that was my case now too.
I asked many colleagues for help and even found a guy that does repairs for the oldest phones (got too excited), but even he couldnt find the issue, besides a guess that its the main chip that partially died on purpose or it got somewhere desoldered by the always and poorly managed overheating issue, which would cost almost the same to replace as just getting a new phone in the end and even then, theres probably a third switch they planned, to give you the final bullet.
I got a Xiaomi Redmi Note 4 now and really gotta say they have an amazing near vanilla android experience and their "two phone" isolated spaces are quite handy to seperate work and private notifications, apps and files.
It was even compatible with lineageOS and has a simple website to unlock the bootloader (a first for me, never saw any company making it that easy), but after trying their version of it, I don't even have to switch.
I will still miss the vibration motor of the g3, the feedback of it when typing is still to this day the best one I ever tried.8
Ffs, I just spent the whole weekend setting up our new storage server. Moved it into the rack. Entered the UEFI to enable idrac. And BAM! The uefi decided to load it’s own raid config over the raid controller.
Raid controller bios doesn’t let me load it’s own config after that. So I have to reset the controller and setup raid, os and the whole shot again.
To make it even better. Debian doesn’t load the firmware for the broadcom chip, since it’s a non-free driver. Making me have to do lots of manual config after the install just to get it on the internet.
I wish I could’ve just bought a new server instead of working with this shit.
I would’ve used FreeBSD with ZFS, but our server only has 8GB ram, and I need about 120GB extra to work smoothly with all the storage.
It’s just a pita working with this. One step forward, ten steps back.
Debug buddy/geeky trinkets thread, because I'm bored, I guess. Here are mine, from left to right:
> Dane-Elec (256 MB, DDR4) RAM stick that I have pretty much every time I go out. School, church, you name it. 256 MB shall always be with me.
> micro:bit (a development board aimed at schoolchildren) that acts as my debug buddy when I debug micro:bit code.
> Another micro:bit that I fried the USB chip on (I think it serves that purpose, might check the specs later) because I wanted to connect an LED to it (I know there's 25 red LEDs to use, but 26 never hurt anyone).
This one just sits in my drawer.
What do you guys have?6
Soo question for the few embedded engineers on here. Do you guys use microchip’s, or NXP’s SDK for the hardware drivers? Or do you read the ref manual and build the HAL and PAL drivers per the need of the project for less code bloat and saving code space.
I and my coworkers always end up writing the drivers ourselves , so we have a better understanding of the specific hardware of the chip. Just trying to see if We’re the majority or the minority of embedded engineers.
Not really sure how many embedded folks are even on here.
And no not talking about RasPie, and arduino folks (no offense)8
On This Episode of Ghetto Medium..
Posted after midnight for extra spooky effects. Read in the dark at your own risk. You've been warned.
So my mother has been on a binge watching shows like long island medium (apparently the taller your hair the closer you are to god or something), and every time we talk she begins at length to talk about, you guessed it.. 'ghosts.'
Now don't get me wrong, I've had some 'spooby' shit occur in my lifetime, the sort that will tighten your sphincter faster than bill cosby asking you if you want some koolaid or grape drank, but I digress.
The ghost talk is tiring. Lately theres been a *flood* of these new shows, purportedly showing mediums and people who can 'look into the other side' and I realize just how vapid and ridiculous it's all become, as if they all are being personally haunted by the ghost of John Edwards burnt out husk of a career. Theres long island beehive big-hair medium, celebrity medium, allison DuBois (the inspiration for that one sappy show *medium*) whos red hair and vacant stare speak of glimpses into centuries past like an intimate unseen horizon. or maybe she forgot to unplug her curling iron in a hotel one time and has been rendered permanently catatonic. And who can forget *Beyond With James Van Praagh* (everyone) whos face, as measured by the width of his mustache, appears to be expanding at a constant rate like a bad image macro edit thats been memed and repasted a thousand times. Then theres Chip Coffee, whos name is about as believable as his teaching degree on the show *Psychic Kids* where he mentored, again, you guessed it, *psychic kids*. Of course theres Tyler Henry, a youthful, uh, "flamboyant" medium for celebrities with ghost problems. Never trust a man with two names, this ones no exception, he looks so clean cut hes either secretly mormon, or secretly gay, maybe both. I'm not judging, but I am saying if I ever saw his clean cut, smooth, wrinkless (seriously, how tyler? how?), all american face, say smiling that subtle smile outside my kitchen sliding glass door at 3 am, his face watching me from the pitch dark outside, I wouldn't at all be surprised, except for the hospital bill I'd have to pay after shitting a brick and needing anal surgery.
At this rate we have mediums popping out left and right, like clowns at one of them R.L Stein nightmare carnivals, or beggers outside a methodone clinic. Geez, they're coming out the wood work, like those painting you see with hidden faces in them, or wheres-waldo posters, only you're trying to find the non-waldo guy amongst all the characters because they're ALL waldo: goofy acting, goofy dressing, and just all around goofy looking.
At this rate I'm fully expecting "pet medium" (starring a character named Stephen King and his marital problems, played by johnny depp eating way to much corn), and "haunted objects medium", and "car medium" (it's just seinfeld in a car, talking to psychics instead of other people), and "ghetto medium."
Today on this episode of "Ghetto Medium"..
Medium: Teneesha, aw yeah girl, u *definitely* ded gurl, uh huh! You WAY to white too be alive, you done passed over gurl!
And in the next episode of Ghetto Medium, one man claims "every time I bend over I can hear "wOoOoOoOoO!, Is my asshole possessed? Find out is it real or fake, and what our verdict is in Ghost Medium, episode 3: A Haunting In My Nether-regions."
Cut commercial break.
"Jerry Springer: One women asks, 'jerry, is my unborn child's foreskin haunted? And later today we ask the crowd, would you have sex with a ghost?"
Welcome to American television 'programming' in 2019.
Yes, it's all brainwashing.2

Viruses are little monsters that eat your computer away (or what's left from it) after it's dead. They start with the heart (BIOS) and then go to the CMOS chip.2
So i have little bit of time today between classes. Grabbed old Xperia P.
Tried U-boot again nothing from UART.
Friend suggested hey that kernel base adress seems not correct change it.
I boot it up.
Display says nothing as expected.
I plug in UART.
ITS FUCKING ALIVE
ITS FUCKING ALIVE
OK for those who dont know what u-boot is well.
Im not fucking google. You are programmers. Go fucking search what it is jeez.
OK with that out of the way. What does this mean ?
Well since one guy was so nice and already did most of the work for U8500 chip then well USB should work.
It doesnt exactly but thats small issue cause EMMC works.
Since EMMC works i can check all the partitions and actually flash mainline kernel on this shit.
And well once Mainline shows me some output oh BOI.18
Im thinking about getting a raspberry pi 3 or an odroid-c2.
(Specs at the end)
Its to host a simple php server and maybe a gitlab server, both for personal use.
Should I go with the better performance or the better community support?

Android emulator would be the worst one for me. To be honest, I haven't used that many dev tech yet, but this thing gave me nightmares.
The one provided by Android Studio sucked ass horribly, and it didn't let me use my dedicated graphics chip (nVidia 740m). If I used it the emulator either my apps would crash or not start at all. After some googling, I found out that this was a common thing more or less...Using virtual graphics on it was slow, sluggish and rubbish with ~1 second delay with clicks and scrolling and shitty screen changes proccessing.
Using Genymotion was no better so I just stuck with the one provided by Google for the time being.
I have to add that most of those apps were tutorial apps, and only 2 were semi-serious.
So I wonder if anybody on here has ever come across the LG G3 flickering screen issue.
I bought a LG G3 about 2 years ago. Fantastic phone.. Until all the issues started appearing.
First of all, the glass started lifting off on the left side of the phone, exposing the backlight layer, because the phone somehow managed to bend (insert iphone joke) inside my pocket. I was okay with it since it was a minor visual thing and didn't affect anything.
About 6 months ago the phone started lagging like crazy, and it kept getting worse and worse. It's so bad right now that Twitter will rarely fullscreen images, apps crash all the time, and occasionally the phone freezes to the point where it won't even react to the lock button.
About 2 weeks ago I started getting messages that my sim card was removed, and the phone starts rebooting itself. This would sometimes happen 10 times a day.
I was already pissed at all of these issues and in a desperate need of a new phone, but on Sunday a brand new issue appeared!
The phone's display randomly shut off, then wouldn't want to turn on, and occasionally turn on just to fade out or flicker away.
I of course went to google to see if anybody else has this issue... And it turns out that youtube is full of videos about it. Apparently the overheating issue these phones have slowly ruins the solder on the chips, which in turn creates a poor connection and causes these issues. The only way to solve it seems to be to reflow the chip, but others that tested that only got it to work for around 2 weeks before the issues started reappearing. I haven't tested it myself yet, but after disassembling, fucking around with it, and putting it all back together 3 times I sort of got it to work to the point where I can use it for several minuted before the displays fails. While writing this rant the display only quit on me once at the very beginning.
What I'm wondering is, why is it that nobody at LG decided to address the heating issue by perhaps throttling the CPU more? And I heard the G3 isn't the only LG phone with these issues?
This crap made me lose all my trust in the company. I wanted to upgrade to a G6 or V30, but because of this crap I think my next phone might be a Xiaomi.
This rant is now so long that it's barely even a rant or on topic. I think I should end it here since I have nothing more to say other than the LG G3 is a beautiful but crap phone, oh, and the new iPhone 8 is a flop9
Switched to LG G5 from iPhone 7 Plus.
Lg's screen has burn in and took me about 10 hours to completely fuck it up, restore it, flash crDroid(Lineage os based, the only custom rom working fine so far) and workaround the faulty wifi chip giving null mac address by faking it.
Still love my new(old) phone more than the iPhone.2
A Dell laptop, specifically the Inspiron one, they never sleep, so I had to do the crime, multiple times a day, it craps itself, it's AMD chip is shit, it's drivers are the word, and last but not least, this laptop was replaced like 6 FUCKING TIMES, and sometimes I used to be in critical situations where I had to use a laptop and guess what, it didn't want to turn on.
So dell, never again.
One day, I was traveling back home from college, and had my laptop in my bag, and guess what I found out when I got home, the plastic parts in the bag fucking melted, ruined my notebooks, and my bag.
Not to mention it's terrible performance thanks to it's drivers while developing shit with Android studio, you know how it is.
In short, don't buy a Dell product. Ever.4
So I bought a LattePanda off Kickstarter last year and only just put it in its new home. Struggling to think what to do with it. At the moment I only use it for streaming video. It's got an Arduino chip in it. What would you guys use it for?9
ESP8266 declared as "GPS Tracker" in "Blindspot" Season 1 Episode 15, i think it was in the first minute, pic taken at 6:55
I think its a esp Wifi Chip, but the crystal confuses me...2
unlimited time is not the only problem. During that time I'd get hungry, cold and tired -- I need to afford to buy food, have a home with roof and warmth. So with unlimited time, I'll also need unlimited funds.
And if I had unlimited funds I'd spend most of my time AFK: buying a house, making it pretty, setting up my own lab and a solar+wind powerplant, recruiting some folks to finish my project for me. Then travel all around the world, while my code monkeys are busy making me famous for introducing new tech to the world - so new, that it'll change the way we live, that it'll change our communication, interaction and other habits. And then I'll be ready for the EternalLife underground project, where another set of teams of bio-monkeys will be busy making my consciousness alive after my body wears out.
If only I had all those funds...
Care to chip in?
My parents are quite supportive of my plan to build myself a decent computer with an actual graphics card (currently I have a laptop with an i7-4600MQ chip & HD 4600 integrated graphics). I might actually get enough money for it in some reasonable amount of time!2
I have another issue 😬 with one of my Ubuntu laptops. The wifi chip somehow has connection issues. It nearly has no signal. I have to be beside the router to get a connection.
I changed the chip to a new Qualcomm Atheros chip already, but there was no change. I tried a few "speed up your WiFi connection" blog posts. But that also changed nothing.
Do you guys have any advice? :-\25
Tl;Dr This guy thinks apple is poised to switch the Macs to a custom arm based chip over x86! He's now on my idiot list.
"They've made a custom GPU", great! That's as helpful as "The iPad is a computer now", and guess what Arm Mali GPUs exist! Just because they made their own GPU doesn't make it suitable for desktop graphics (or ML)!
"They released compilation tools right when they released their new platform, so developers could compile for it right away", who would be an idiot not too...
"Because Android apps run in so many platforms, it's not optimized for any. But apple can optimize their apps for a sepesific users device", what!? What did I miss? What do you optimize? Sure, you can optimize this, you can optimize that... But the reason why IOS software is "optimized", and runs better/smoother (only on the newest devices of course) is because it's a closed loop, proprietary system (quality control), and because they happen to have done a better job writing some of their code (yes Android desperately needs optimization in numerous places...).
I could go on... "WinTel's market share has lowly plataued", "tHeY iNtRoDuCeD a FiElD pRoGrAmMaBlE aRrAy"
For apple to switch Macs to arm would be a horrible idea, face it: arm is slower than x86, and was never meant to be faster, it was meant to be for mobile usage, a good power to Wh ratio favoring the Wh side.
So, I've been seeing a lot of people concerned about privacy around here lately.
I completely understand it, and I too, don't want all my data to be available for anyone at any given time. I get it.
However, the only way to get privacy, is to build it yourself.
Buying a phone? Who says (apart from the company itself) that it doesn't have some integrated chip, or that the os lies to you or w/e
When using your phone, who says your Sim provider isn't intercepting all your traffic with a man in the middle attack?
These sound like conspiracies, however, if you really want privacy, either build it yourself (or with other privacy activists) or let go of the comforts of technology (i know, you're not the only source of info about yourself, the only way to shield yourself is to go into the woods and live a simple life.)
It's pretty sad that these are the two options, but I've yet to find a better one.
(ps, I used to have a "no logs, no ip, no anything" VPN provider, and as soon as some agency requested info, they got it, so I wouldn't easily trust the promise of 3rd parties anymore.)12
Any recomendation on a mini board/micro pc/chip etc, somenthing really small that can run linux and open a browser?? Just to connect my tv to it and be able to surf on the web, somenthing ligth, won't do any heavy stuff with it. Cheap if possible
My experience with getting Linux on my dell i7559 was not so good. So, here is a tiny blog post, just to help a fellow ranter.
Follow up on my printer rant.
(Quick recap: my printer uses all colours when printing black and white, and it says the cartridge is empty when it isnt at all)
I finally have it figured out.
The current cartridges dont get used (for some reason) and i bought a chip resetter. I just reset the chip of the colour cartridges and I buy a black cartridge every now and then. Essentially making my printer black and white only, just how I like it.1
I’ve a raspberry pie 3B.
The pi boots up with the OS previously installed on it, theHDMI port works perfectly,
The problem is , I can’t get the USB ports to work, nor does the LAN port works. And the wifi also doesn’t connect automatically donno why , not sure if the wifi wasn’t setup or the chip is gone bad, just need to know what I can do with it4
Debugger chip attached to my brain. That would save me so much time and effort. Also some money from not needing to buy state-of-the-art programming tools.1
Who ever thought that creating WCN3980 was a good idea i hate you.
So lets see the story shall we ?
Naive me jumps on the mainline tree.
Everything goes well with the phones we ported.
We have touch and all that jazz.
Now came Bluetooth.
Then the all mighty QCOM decided that downstream they will use some shitty driver to make this piece of shit work.
While the more smart people of upstream (mainline) decided that hey lets do the driver the proper way.
So they did.
Now comes the funny part.
The BT chip isnt connected to SoC normally as one would expect.
It is via UART.
Which is fine you think. Until you take a look how downstream and upstream handle it.
On upstream we have it the proper way of assigning BT node as a subnode of UART.
On downstream ? Just define the BT node as normal node. Driver will figure it the fuck out.
Now on this SoC we have 4 UARTs.
2 of which are crashing\freezing our phones when we enable them.
So lets try the other 2.
1: It boots up which is good but ultimately fails that frame reassembly failed with -84 aka illegal byte sequence.
Yea thats not good.
2: It also boots up and now doesnt throw -84 error on me.
What it does do tho is throw at me timeout error for the chip turning on sequence. (-110)
Then i figure out that 1 vreg (Voltage Regulator) is incorrect. So i fix that.
I left it like this for a while.
I got back to it week or so ago.
The vreg was wrong noticed one of the other guys im working with on this.
So we implement the new regulator type.
I pass it to the driver hoping we get BT but no. Same error.
Today i made the ultimate discovery.
That vreg we set ?
Yes i know by this time its getting crazy but this is making me go nuts
The downstream didnt set VDDIO they set chip power.
I looked in one place. Found the real 10000000% correct regulator for it. Turned it on anddddddd BT still not working.
OK hmmm what if i try setting all the voltages to as the chip wants them to be to be turned on.
BT still not working.
And this is where im right now. Stuck on this piece of shit thing.
I have some ideas what can be wrong. Most of them have been proven wrong by me from testing already tho.2
Today's Friday, so I've gotta go into my clients office. Time to throw on some chinos and pretend that I act like a civilized human being the other 6 days of the week... *glances at chip bag and popcorn container*
You have to work, but you notice a fiber in your web cam. Clean the lens, but its still there. Open the web cam to the last bit and clean the optical chip.. There you fixed the web cam, but what about the work..
I want to buy a laptop; so I went with the MSI GS66, but I don't know which option to choose, the 2070 Max Q or the RTX 2060. Both have about the same performance, but I don't know if the bigger RTX 2070 Max Q chip will affect battery life. Is the RTX 2070 Max Q worth the extra 300 dollars. Will it affect battery life? Will it run hotter?10
Is there anyway to copy any nfc chip and replicate its id through your mobile, i have the nfc retag pro app and wonder if i can do so through it?1
The WiFi/Bluetooth chip in my SP3 died. Now I have to plug in this stupid adapter in my only USB port. So, that being said...
Ranters, best 2-in-1 convertible laptop, go!5
I'm never committing to finishing another PC game ever again... And sticking to arcade, short games only.
Playing Nu no Kuni 2 for the last 3 days... 25hrs and counting... Now at final boss... I think and I can't get infinite HP in Skirmish... So Keep getting entire force wiped out one hit with his laser beam which keeps getting stronger....
It's like a fly vs us. In order to win it's gotta slowly chip away at u, but he can die at an instant any time...
Oh and the 25hrs includes massive cheating and speed hacking to move faster.2
Started the day with trying to install a simple package which can read an RFID chip. Wasted the whole day trying to fix dependencies, still not done. Sometimes I just hate linux....
• 6.9B transistors
• 6 CPU cores
• 4 GPU cores
• 8 “neural” cores
• 5 trillion ops/sec
• 512GB addressable storage
• Oh and the rest of the “stuff” for a SoC
tl;dr Apple is the leading chip innovator and creator in the world.
Don't @ me4
Remember in the Matrix how they learned things just by scanning a memory chip into their brain?
I think that's how learning programming languages should be...the technology should exist to make that happen :(1
So, I've successfully finished my final project, but at some point I was having massive troubles.
For some fucking reason, the chip select line was not going high after turning low...
Apparently the led was pulling it down permanently...
Another weekend wasted...
