https://git.kernel.org/…/ke…/... sure some of you are working on the patches already, if you are then lets connect cause, I am an ardent researcher for the same as of now.
So here it goes:
As soon as kernel page table isolation(KPTI) bug will be out of embargo, Whatsapp and FB will be flooded with over-night kernel "shikhuritee" experts who will share shitty advices non-stop.
1. The bug under embargo is a side channel attack, which exploits the fact that Intel chips come with speculative execution without proper isolation between user pages and kernel pages. Therefore, with careful scheduling and timing attack will reveal some information from kernel pages, while the code is running in user mode.
In easy terms, if you have a VPS, another person with VPS on same physical server may read memory being used by your VPS, which will result in unwanted data leakage. To make the matter worse, a malicious JS from innocent looking webpage might be (might be, because JS does not provide language constructs for such fine grained control; atleast none that I know as of now) able to read kernel pages, and pawn you real hard, real bad.
2. The bug comes from too much reliance on Tomasulo's algorithm for out-of-order instruction scheduling. It is not yet clear whether the bug can be fixed with a microcode update (and if not, Intel has to fix this in silicon itself). As far as I can dig, there is nothing that hints that this bug is fixable in microcode, which makes the matter much worse. Also according to my understanding a microcode update will be too trivial to fix this kind of a hardware bug.
3. A software-only remedy is possible, and that is being implemented by all major OSs (including our lovely Linux) in kernel space. The patch forces Translation Lookaside Buffer to flush if a context switch happens during a syscall (this is what I understand as of now). The benchmarks are suggesting that slowdown will be somewhere between 5%(best case)-30%(worst case).
4. Regarding point 3, syscalls don't matter much. Only thing that matters is how many times syscalls are called. For example, if you are using read() or write() on 8MB buffers, you won't have too much slowdown; but if you are calling same syscalls once per byte, a heavy performance penalty is guaranteed. All processes are which are I/O heavy are going to suffer (hostings and databases are two common examples).
5. The patch can be disabled in Linux by passing argument to kernel during boot; however it is not advised for pretty much obvious reasons.
6. For gamers: this is not going to affect games (because those are not I/O heavy)
Meltdown: "Meltdown" targeted on desktop chips can read kernel memory from L1D cache, Intel is only affected with this variant. Works on only Intel.
Spectre: Spectre is a hardware vulnerability with implementations of branch prediction that affects modern microprocessors with speculative execution, by allowing malicious processes access to the contents of other programs mapped memory. Works on all chips including Intel/ARM/AMD.

Me: Your computer has Operating System corruption.
Customer: What does that mean?
Me: *something, something potato chips* and the only fix is to reinstall Windows.
Customer: Well that's stupid! I need my computer! Darn Windows! Microsoft should pay for that reinstallation! What causes that corruption anyway?
Me: Well, any number of things, but it's mostly caused by a part of the update not downloading correctly, so when it gets installed it creates a hole.
Customer: So now hold on... could shutting the computer down during the updates cause this corruption.
Me: It could, yes. That's why they say to not unplug your computer or shut it down while running the updates.
Customer: I see. Cause yeah, I remember that I was angry when it said it had to do updates, so I shut it down.
Me: Yep, that would cause it.
Customer: Okay, reinstall Windows...10
I'm getting ridiculously pissed off at Intel's Management Engine (etc.), yet again. I'm learning new terrifying things it does, and about more exploits. Anything this nefarious and overreaching and untouchable is evil by its very nature.
(tl;dr at the bottom.)
I also learned that -- as I suspected -- AMD has their own version of the bloody thing. Apparently theirs is a bit less scary than Intel's since you can ostensibly disable it, but i don't believe that because spy agencies exist and people are power-hungry and corrupt as hell when they get it.
For those who don't know what the IME is, it's hardware godmode. It's a black box running obfuscated code on a coprocessor that's built into Intel cpus (all Intell cpus from 2008 on). It runs code continuously, even when the system is in S3 mode or powered off. As long as the psu is supplying current, it's running. It has its own mac and IP address, transmits out-of-band (so the OS can't see its traffic), some chips can even communicate via 3g, and it can accept remote commands, too. It has complete and unfettered access to everything, completely invisible to the OS. It can turn your computer on or off, use all hardware, access and change all data in ram and storage, etc. And all of this is completely transparent: when the IME interrupts, the cpu stores its state, pauses, runs the SMM (system management mode) code, restores the state, and resumes normal operation. Its memory always returns 0xff when read by the os, and all writes fail. So everything about it is completely hidden from the OS, though the OS can trigger the IME/SMM to run various functions through interrupts, too. But this system is also required for the CPU to even function, so killing it bricks your CPU. Which, ofc, you can do via exploits. Or install ring-2 keyloggers. or do fucking anything else you want to.
tl;dr IME is a hardware godmode, and if someone compromises this (and there have been many exploits), their code runs at ring-2 permissions (above kernel (0), above hypervisor (-1)). They can do anything and everything on/to your system, completely invisibly, and can even install persistent malware that lives inside your bloody cpu. And guess who has keys for this? Go on, guess. you're probably right. Are they completely trustworthy? No? You're probably right again.
There is absolutely no reason for this sort of thing to exist, and its existence can only makes things worse. It enables spying of literally all kinds, it enables cpu-resident malware, bricking your physical cpu, reading/modifying anything anywhere, taking control of your hardware, etc. Literal godmode. and some of it cannot be patched, meaning more than a few exploits require replacing your cpu to protect against.
And why does this exist?
Ostensibly to allow sysadmins to remote-manage fleets of computers, which it does. But it allows fucking everything else, too. and keys to it exist. and people are absolutely not trustworthy. especially those in power -- who are most likely to have access to said keys.
The only reason this exists is because fucking power-hungry doucherockets exist.26
Anyone who remembers my last rant about getting fake chips might enjoy this.
After realizing that the EEPROMs I got last time were counterfeit, I bought a new set (and different model) from Atmel. They were super easy to hook up, and the best part is they actually work! Behold, my bit-by-bit EEPROM programmer:10
Friend of mine killed his MacBook with some Softdrink.
Just poured it all over his poor a1502.
He let it dry for a few days, it starts to work again.
Except the battery.
Goes on Amazon and buys a new battery.
New battery doesn't work either and so he tells me about it and I as stupid as I am couldn't resist the temptation to finally work on a MacBook like my "hero" Lois Rossmann does.
So turns out the board is good.
Cleaned it up and basically nothing happened to it.
So what's the deal with "los batlerias"?
The first got hit by liquid, the second had a broken connection to a cell.
That could have happened through my friend, installing it without testing it first, or at the seller, so it being a DOA battery.
Now away from the stupidity of my friend and the situation to the actual source for this rant.
Once something happens to a modern Managed battery, the Battery Management System (BMS) disconnects the voltage from the system and goes into an error state, staying there and not powering anything ever again.
For noobs, it's dead. Buy a new one.
But It can be reset, depending you know how to, and which passwords were set at the factory.
Yes, the common Texas instruments BQ20Zxx chips have default passwords, and apple seems to leav them at default.
The Usb to SMBus adaptors arrived a few days ago and I went to prod the BMS.
There is a very nice available for Windows called BE2works, that I used the demo of to go in and figure out stuff. The full version supports password cracking, the demo not.
After some time figuring out how Smart Battery Systems (SBS) "API" works, I got to actually enter the passwords into the battery to try get into manufacturer and full access mode.
Just to realise, they don't unlock the BMS.
So, to conclude, my friend bought a "new" battery that was most likely cut out of a used / dead macbook, which reports 3000mah as fully charged instead of the 6xxx mah that it should have, with 0 cycles and 0hours used.
And non default access.
This screams after those motherfuckers scaming the shit out of people on Amazon, with refurb, reset, and locked fucken batteries.
I could kill those people right now.
Last but not least,
My friend theoretically can't send it back because I opened the battery to fix the broken connection.
Though maybe, it'll get send back anyway, with some suprise in the package.9
Today I learnt that my LG Nexus 5X uses a Samsung manufactured DRAM :O
I had no idea that several Google and Apple devices use Samsung manufactured RAM chips!
PS - Don't judge me, I'm a hardware noob.17
Customer: So I have operating system corruption? What does that mean?
Me: *thinks for a moment* Okay, so you have a bag of potato chips, right? And you're looking forward to eating those potato chips. However, when you open the bag, there are only crumbs because the guy in front of you in line had accidentally stepped on the bag and crushed them all.
Me: So what we can do is we can grab a can of Pringles--because Pringles are delicious--and dump those in the bag. That way you have a good, full bag of uncrushed digital potato chips.
Customer: I like that, let's do it!
Coworker: ...why are you talking about digital potato chips?8
All the beloved citizens are hereby informed that such RFID chips will be available for everyone soon and it is an honest request to everyone to get these implants as soon as possible.
Thank you for Co-operating, Have a nice day :)32
me: yo, im kinda low on cash right now, i should save some money and not do any iot projects this month
also me: yo, look at those nfc chips, i got an idea1
It has officially been piss on my chips day.
1 bus pass refused to work today.
2 my pixel decided it would die. Will not boot or charge.
3 go on lunch and get battered by hailstone.
4 work pc decided it wants to blue screen whilst updating.8
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
cw: I need a server to put my node backend
me: sure, I'll run a docker container for you
cw: nice, I've never worked with docker but I learn quickly, I'm already reading the Docker file docs
me: no wait, you don't need to learn anything, you'll be inside the container, so you only need an ssh connection and that's it
cw: this Dockerfile stuff is really complicated, it'll take me a while, but it's ok you don't have to worry, I like learning new things
me: you won't need that, just imagine it's a cloud server with Ubuntu installed, you only have to use it, I'll put node, git and ssh there for you
cw: ok got it, I'll have to learn the commands to run the docker, I'm on windows but I can use PowerShell and stuff I'll figure it out
cw: ssh is a linux command right? does it have a push or publish option? how do you upload files there
me: ...you can use a ftp client but you'll need ssh to run the node server
cw: ok, I'm almost done with the Dockerfile, I only need to add git and nodejs, I'm starting to understand this thing...
me thinking: yeah keep doing that, you're such a crack, such a quick learner...
This son of a bitch is either a retard or is doing it on purpose and laughing at me the whole time, making my life so miserable, but I'm about to go insane with this dude, I'm proud of how I've been able to control myself, BUT ONE OF THESE DAYS I'LL LOSE MY COOL AND FORCE THIS MOTHERFUCKER TO DRINK A BIG POT OF BOILING, SALTY AND STINKING VOMIT WITH A SIDE OF STEAMING DIARRHEAL GREEN DOG SHIT WITH WHITE CHOCOLATE CHIPS WHILE I PUT MY OLD CRT MONITOR TO GOOD USE BY BEATING HIS FUCKING HEAD WITH IT!!!3
It feels like 1985..
Not,1986, as in that year, we got Blitters for smooth screen scrolling ! (Though, if you knew what you was doing, you could make smooth screen scrolling before Graphic Hardware chips started doing some of the work for us..)
I drag a window across several monitor screens, why is it not smooth, why do I have to fight it like I'm wrestling an alligator !
Maybe it's my weak GTX 750Ti 4Gb graphics card, or the 3.4Ghz quad core CPU..
Instead it feels like FAST MODE on a ZX81..17
TLDR; younger brother is an unreliable fuck. Learning to be a pathetic trickster. Penny teller cheap ass jester.
Hello folks. Time for a little family story.
This started around mid June.
I was a little tight on money the past few months. I had a broken laptop, that my brother wanted to buy. So I told him that he can have it for 100 bucks. It was a 1k gaming laptop 2 years ago, (i7, gtx 960m, 16gb ddr4). But I didn't know how much it would cost to repair. So I was happy with the price and so was him.
He told me he would pay by the end of June.
Hi didn't pay. He repaired the laptop for free by asking his boss, that used to be my friend (I'll probably tell you guys about that in another rant, best friend, got in a fight, stopped talking, next day my brother asked him for a job).
A month later, mid July, I told him I needed the money.
He literally said:
"I don't care for what you need. I'll pay you when I think it is a relevant expense, now I have money only for buying tools and investing in my career".
He was buying 15 usd pens (not only 1), because he wants to have expensive crap.
That was a bit disgusting, but not shocking. (I'm used to his little brat attitude, he's 26 btw).
I thought to myself. Ok, you want to be a bitch?. Then pay more.
I told him that he appreciated a good that wasn't his and that he should either pay now or agree to a new price. He didn't like that idea, but eventually we agreed to make it 300usd.
And one of the clauses was.
"I shouldn't ask him to pay." 🙄
He would pay when he could. (entitled brat attitude again). Ok. Fine.
It's been a month from that. He teased that he would pay 3 weeks ago. And he didn't. I asked him how was the "not asking for payment clause", because he did the teasing and I wanted to know if that kind of shitty mind games was part of the deal.
So that's the background story for the laptop.
Now time for a dinner story.
We share dinner once or twice a week. And when any one is short in money we keep a tally on who's been paying.
When I have money I just let the tally go in my favor, an buy him dinner whenever he says his short on money.
Note: Here, fries and soda are not part of the price, so the one that is short on money pays the fries and soda.
Today it was not one of those days. (Dinner here is about 15 USD for 2, with fries, and soda, nothing fancy, nor healthy, but an exuse to hang out with my only brother that would not eat a salad even if it was free).
I owed him 10 bucks, and he owed me 1 dinner. I asked him if he's buying dinner today. He said that the tally is even because last meal I didn't pay the chips. 🧐. (That was settled because I didn't pay once, but made up for it later)
Again with his entitled ass shitty attitude.
I just said. I don't want to hear your excuses. Here's your money. I want my laptop tomorrow, I'll sell first thing Monday. And tell me how much did you spend on repairs and parts and I'll pay you.
And now I'm sad. 🙃
Mainly, because is just so fucking boring to deal with a person that counts every penny. I fed him for 10 year while he was having problems, (alcohol and depression), And now he comes with this shitty ass counting pennies attitude, wtf?
I literally felt poorer just by counting the cents that made part of this story. (Really, who the fucks keeps track of chips and soda??? What are we 15yo??)))
It's one thing to be trapped in a 3rd world country where everyone is trying to fuck you. You learn to deal with that shit. And it's ok.
But seeing that your little brother is learning the same cheap trickery is just sad. The same cheap approach to life. The same easy and pathetic mind games is just fucking sad.
I don't even mind the money anymore. I was short on cash 2 months ago, I'm gladly better now. But finding out that he's becoming a little scammer is a bummer.
I just needed to vent. I think I should stop enabling him. And maybe keep some distance, it is fucking depressing to be counting cents to settle an argument. By dealing with that fucktard I end up counting cents just to figure out who's right.11
When it's dark outside all the time and the sun suddenly comes around.
Everyone's going crazy about it and walking outside.
Me: FUCK. How am I supposed to read my freakin code like that?!
*Me standing up and closing the shutter*1
!rant && !!rant
☝️ What does that give you?
Today will be the last day we gonna work at this fucking hellhole of an office. Since I had so many shits to remember from this office, let me share my favorite.
1) Ground floor. Got flooded last July. Half our equipments got soaked. Oh equipments as in computers, cables, reports documents, etc etc.
2) I am gonna miss those connection down days.
3) I will also miss those black out days where we couldn't work for hours so had to play teamwork games to keep the morale of the team and you know to stay awake.
4) I will also miss that fucking mouse or rat. You are small and cute but fuck you for chewing my potato chips and peanuts. A-hole.
5) No windows so with no air-conditioning, it is a literal hell hole.
Gotta stop. I might cry.17
I am so fucking sick of hardware design and integration projects.
First thought, let's outsource. Except the best quote we got was $2.8M for a fucking 10 by 10 board with 200 components. What the dick shit is this did I send the email as Bill fucking Gates or something so they all thought I'm shitting gold bars?
Micro X comes with awesome frameworks and SDKs but you can't use it because it doesn't have those extra 2 pins you need.
Micro Y has them but they're not 5V tolerant so you can't use the $8 chinkese relay board, you have to add your own onboard relays which will cost you $25 and a blowjob for some FUCKING RELAYS
Then there's micro F to the rescue! enough pins, 5V tolerant, awesome SDK give or take a few months guessing how the fuck to use that 40Mb of C code library & fixing someone's fucking code, but wait, you can't use it because it has no external interrupts so basically you have to keep polling inputs and can't go to sleep, so you need to run the core at full speed and guess what the fuck it is more power hungry than the hottest trophy wife at 200mA.
No problem, fuck this shit, let's go STM like I told you so in the beginning - but I should be the one to pick the micro and all power components. Here's the specs, call me when it's done, we'll fuck with some of the web apis in the meanwhile. 2 weeks later: fuck all of you, I can't find what you need!
Then smartass #173 comes with the brilliant idea to try them chinkese PLCs with integrated HMIs, wtf they're cheaper than what you idiots are building?!. Sure, let's go for it. Spend $3000 on test units, wait 8 weeks because EU customs and taxes, then finally - NONE are usable despite the suppliers who swear it works, it has transistors on outputs, i'll be fucked it even lets you stick your cock in and gives you a tickle.
Then dickweed C-motherfucking-TO goes like, sure, let's go bare metal again, wtf we are old hardcore fucks with big cocks, plug a $8 pic24 and it will do the job. Except you have to spend 18935718 fucking years writing everything in C and when you're almost done guess what the fuck happened, we still need another micro so we can have ethernet and connect to a MQTT server.
No problem, trash all the work, let's pull the big guns, pic32mx-what-the-fuck, spend 1 month getting the toolchain to work and 2 more months writing all sorts of fucking signs and dashes and commas and brackets in MOTHERFUCKING C again and when we all think omfg we're done, some moron decides to test the board at high humidity and low temp and guess what the fuck happens - it breaks because that shit isn't rated what we need, but the fucktard was on paternity leave 5 eons ago when we started because his fucking wife gave birth and he couldn't spend a couple hours testing a blinky in his own fucking house in the fridge or wherever the fuck, so he just said yes and now guess what - we're all fucked.
Then let's try this shit board, it has the USB support and we can put one of them cheap ass ethernet chips, we'll just connect it to android via OTG and let the fucking google connect to the API over 3G. Except motherfucking android and its usb stack add some 100ms of latency which is basically more than I need to cook 3 fucking meals or some idiot needs to die electrocuted because the estop button doesn't shut down the relays fast enough.
2 years later I still don't have a workable prototype. Fuck my life. Fuck whoever planned this shit, they must have been brain fucked, in fact fuck this shit altogether. Fuck computers and processors and servers and micros and every fucking atom of copper in this fucking house.3
Alright. Two dead Commodores.
Over 15 years before I was born? ✅
No idea how BASIC works? ✅
Internet at the ready? ✅
So far I've checked various chips for visible damage, and nothing except a blown fuse on both machines. Apparently it takes dual 9vAC and single 5vDC. The 9 powers the SID and the video output, the VIC-II heatsink is off, and I've tested the PSU voltages and one of the 9v's is dead. I'll be getting new fuses and a new PSU soon. Any recommendations on other things to check or things to do when they're done? Pic included because why not.12
I worked for a company who supplied CERN with some ultra high end equipment.
At one point the guys at CERN email me "Problem, check this out."
The picture was of some burnt out ultra expensive cards that fit into a larger chassis... the cards looked like they had been exposed to a fire that was located exactly between the cards, but none of the cards themselves looked like they had been on fire. The chips and such looked burnt, but more so exposed to a very hot fire, not like they were on fire themselves.
It was weird. I sent them some crates to securely ship them to our QA folks, and ordered them up about $500k in replacement equipment.
QA later said they never got the equipment, someone "from another department" picked them up from the dock. And CERN never asked about what QA found, that was weird because they always asked.4
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
There's just way too many choices when it comes to buying a new pc. And then there is Intel. Granted they produce great chips. But the whole cpu market is under their control. They are releasing new chipsets and sockets for breakfast.
We need stronger competitors4
Had a mental breakdown a few days ago. Crying like it's the end of the world when computer stopped working. I was a Picasso drawing of the hysteria, basically.
My exams are getting near, I'm really not ready; yet this chick keeps asking me about ten euros I borrowed from her a year and something back when we were going to a club they asked me to go to with them... Given her persistence that I should wire her the money (no PayPal tho) I assume she's up to something super shady. Why does she need my account info for?
Anyways, being annoyed by only ten euros (in our currency, it's not much, btw. It's less than two bags of expensive chips, or 5 dozen of the cheapest eggs on the market) and not studying enough, there is also my work. I feel so incompetent that I may just resign. Like... I'm not smart enough for this project. 😢 And I'm aware of it.
Put that on the side with this uni's project, which is very "Urghhhhh" because of too many people working on the same project, some of who need to be sent back to kindergarten to learn how to cooperate with others.
And in the middle of all of that, I'm trying to stay as zen as possible until the next mental breakdown. 😑😑😐
Thank you for reading this rant.7
Found this on Quora today :
Programming isn't sexy at all. In a club, try picking up a girl by telling her your heroic tale of saving an entire department by rewriting a recursive function to take advantage of a feature in the new server Intel chips to scale up their online orders.
Then tell me how it goes.4

Transistor sizes are getting smaller and smaller by the day, though we cannot go below the size of a virus due to compartment limitation but the tiniest is smaller than a DNA.
Having chips designed at such a tiny scale looks more scary to me than amazing. Imagine my manager screaming at me, I can give him a slap on the face and infect him with 1 million A8 chips. Now that would be amazing because I just successfully turned him into an iPhone 6.
Me: Hey Siri, what's the weather now?
Manager: 32 degree Fahrenheit, high wind, low humidity.
Me: Yeah that's what's up, you won't be needing an upgrade anytime soon.10
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
When i ask you a question through skype or mail, I expect a fucking answer.
You might just say that you don't know. That is okay.
But we all fucking work from home and I can see you're there. FUCKING ANSWER YOU INCOMPETENT, USELESS, UNPROFESSIONAL SACK OF SHIT.
It is so fucking counterproductive. I fucking hope all the chocolate chips in your life turns out to be raisins.
It is fucking impossible to underestimate these people.
I am seriously jealous of all of you here on devrant, for not having met these washed up twats.10
Hey DevRant fam! Hope you are all doing very well wherever you may be. This is not a dev related post but just something i wanted to get off my chest , 20 minutes ago I watched the movie “night school” along side my brother. I was sat down along side two girls on my left and i thought “hey they seem nice” in my mind.
Well i was wrong - throughout parts of the movie she would randomly turn to give me a weird look, as if i was something else? Unfortunately i suffer from eczema and really cant help it and have to undergo treatment monthly and with that comes bullying and judgement from randoms.
What really broke me was that she had the nerves to comment loudly to her friend right next to her about me, say things like “ damn is he ugly “ and many things along those lines, and also about how i ate my pringles? Like hey i love my pringle chips!.
At the end, movie done, my brother is happy I’m happy(not really) we both got up the two random girls walked in front and just gave me this weird stare and had to judge me by the way i walked, thats a whole other issue but i just wish they would have the thought- how would you feel if you put yourself in my position and have to go through my emotions you put me through because you wouldn’t think before you speak ? :-( well thats not everything but some of what i have to deal with unfortunately - sorry this is so long.
Hope all is good for everyone- thank you ☺️
"I was gonna get a candy bar; the button I was supposed to push was 'HH', so I went to the side, I found the 'H' button, I pushed it twice. Fuckin’…potato chips came out, man, because they had an 'HH' button for Christ’s sake! You need to let me know. I’m not familiar with the concept of 'HH'. I did not learn my AA-BB-CC’s. God god, dammit dammit. " - Mitch Hedberg
For decades, the computer industry has been talking about replacing silicon in future chips.
AMD finally did it - all of their more recent chips are made of military grade unobtanium!8
So all these year's i've been living a lie? I thought my current i7 laptop has 4 cores but according to a lot of articles are saying mobile chips only have 2 cores?
Why does Windows always say it has 4 though?26
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".
So Google have come out and confirmed 100% that the Pixel 4 contains project Soli chips and the required radars for touchless gestures....
Need it, need it, need it, need it!!!
Fucking keen to start developing using it even though I'll probably never release anything .-.11
*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
OK can we agree the WORST feeling is when you're just sitting around consciously procastinating and you're just overly aware that each second that passes is more time wasted and you like watch hours pass and you're STILL procastinating and you CAN'T STOP and your panicked brain is trapped inside a body that refuses to be productive and inside you're screaming but outwardly you're just eating chips.9
Why is it I buy a new phone for $500, then within a year it's only worth $50 and a packet of chips?1
-_- every time I use windows recently, I'm reminded of why I haven't for years... I swear, the simplest things are so freaking hard to do. It's like, windows doesn't support W, but blog post A references program B, which converts Z into Y, and after spending 3 more hours googling I find programs C and D, which convert Y into X, and then X into W. Were you able to follow along? Yeah, neither can I. The logo comes up and I immediately get PTSD and start falling down Alice's rabbit hole only to realize I've just wasted 5 hours of my life...
Unfortunately, ASUS is horrible and refuses to make even the most basic, minimally-functioning Linux drivers, or provide anybody with the resources to do it themselves, and they put everything on GPIO chips capable of frying the laptop!!! I'm so freaking done...
I feel like an adult locked in a child-safe playroom full of baby toys...31
Tried to reply to @Fast-Nop who had replied to someone wondering if C would be a good first language.
IMHO C should have been put to sleep ages ago. A few years ago I downloaded the latest, greatest C Standard. For a language billed as small and simple (by many) it was over 800 pages long. Still there's a lot that's unspecified like order of evaluation of function arguments. Int etc is implementation dependent. And error handling, let's not go there. The macro assembler throws away all the semantics leaving behind a cryptic value. It's a complex language due to the innumerable interactions possible.
It's been called assembly language for the PDP-11 minicomputer. Recently learned that even the VAX-1 was built from SSI chips like the 4-bit 74181 ALU. The VAX.
Anyway I had several excellent books on programming style written by Henry Ledgard. He despaired of making C look readable. I commend his books which are so old that the code is UPPERCASE A lot of he wrote had to do with program design, naming things, writing good comments and that the visual shape of a program assists mental clarity.24
While attending an internal training session (some joining the meeting online and some present in the room), an online attendee did not mute their microphone and proceed to eat a packet of crisps/chips. And not softly, but like a horse.
We were also recording it, so now we can listen to it over and over ...1
Dear dongle manufacturers, I love USB-C, I think everyone does; it is the bomb... But.... But but but, please stop charging so much extra for it, I can get a USB-A to Ethernet adaptor for $12 AUD but it's going to cost me at minimum $49 AUD for the same branded dongle, even has the same internal chips... Why... Just... Why!17
Are you the nocturnal developer who lives on red bull and chips or the luxury developer who works in a beautiful light office and is a vegetarian?11
A bug is born
... and it's sneaky and slimy. Mr. Senior-been-doing-it-for-ears commits some half-assed shitty code, blames failed tests on availability of CI licenses. I decided to check what's causing this shit nevertheless, turns out he forgot to flag parts of the code consistently using his new compiler defines, and some parts would get compiled while others needed wouldn't .. Not a big deal, we all make mistakes, but he rushes to Teams chat directing a message to me (after some earlier non-sensible argument about merits of cherry picking vs re-base):
Now all tests pass, except ones that need CI license. The PR is done, you can use your preferred way to take my changes.
So after I spot those missing checks causing the tests to fail, as well as another bug in yet another test case, and yet another disastrous memory related bug, which weren't detected by the tests of course .. I ponder my options .. especially based on our history .. if I say anything he will get offended, or at best the PR will get delayed while he is in denial arguing back even longer and dependent tasks will get delayed and the rest of the team will be forced to watch this show in agony, he also just created a bottleneck putting so many things at stake in one PR ..
I am in a pickle here .. should I just put review comments and risk opening a can of worms, or should I just mention the very obvious bugs, or even should I do nothing .. I end up reaching for the PM and explained the situation. In complete denial, he still believes it's a license problem and goes on ranting about how another project suffering the same fate .. bla bla bla chipset ... bla bla bla project .. bla bla bla back in whatever team .. then only when I started telling him:
These issues are even spotted by "Bob" earlier, since for some reason you just dismissed whatever I just said ..
("Bob" is another more sane senior developer in the team, and speaks the same language as the PM)
Only now I get his attention! He then starts going through the issues with me (for some reason he thinks he is technical enough to get them) .. He now to some extent believes the first few obvious bugs .. now the more disastrous bug he is having really hard time wrapping his head around it .. Then the desperate I became, I suggest let's just get this PR merged for the sake of the other tasks after may be fixing the obvious issues and meanwhile we create another task to fix the bug later .. here he chips in:
You know what, that memory bug seems like a corner case, if it won't cause issues down the road after merging let's see if we need even to open an internal fix or defect for it later. Only customers can report bugs.
I am in awe how low the bar can get, I try again and suggest let's at least leave a comment for the next poor soul running into that bug so they won't be banging their heads in the wall 2hrs straight trying to figure out why store X isn't there unless you call something last or never call it or shit like that (the sneaky slimy nature of that memory bug) .. He even dismissed that and rather went on saying (almost literally again): It is just that Mr. Senior had to rush things and communication can be problematic sometimes .. (bla bla bla) back in "Sunken Ship Co." days, we had a team from open source community .. then he makes a very weird statement:
Stuff like what Richard Stallman writes in Linux kernel code reviews can offend people ..
Feeling too grossed and having weird taste in my mouth I only get in a bad hangover day, all sorts of swear words and profanity running in my head like a wild hungry squirrel on hot asphalt chasing a leaky chestnut transport ... I tell him whatever floats your boat but I just feel really sorry for whoever might have to deal with this bug in the future ..
I just witnessed the team giving birth to a sneaky slimy bug .. heard it screaming and saw it kicking .. and I might live enough to see it a grown up having a feast with other bug buddies in this stinky swamp of Uruk-hai piss and Orcs feces.1
Just got a new job.
All good, really enjoying it.
Only problem is, the canteen smells of chips and it's making me very hungry... Water for me :/9
I just hate how my body believes that coding time and snack time are synonyms. Like ok, i might have been eating some chips or noodles while i was doin' the thinking, but hell, i cannot just empty 2 or 3 bowls of food each time i have to open and IDE.. How can you guys keep yourselves busy from eating when you fight the evil forces of bugged code?3
After 4 years of reading about various technologies of the tech world , like how chips and circuits work, the maths of integration differentiation, probabilities, random variables, compilers,os, networking, machine learning, big data, databases, ai, cloud , ... Etc
What am doing as a job these days is basically writing code in xml and kotlin to render views(aka colorful texts, buttons,..etc ,basically ui) for android apps that will show or hide based on response from the server, and also parsing that response into various dto's and models...
Its kinda cool , being in touch with the top layer of an os, but there's a lot more in the world of technology, isn't it?
I mean , even if i look into the jobs of other team mates, there isn't much difference. Like the testers are just taking our builds everyday and trying to find faults, the backend guys are fiddling with similar code as ours, i guess the only difference would be they handle some stuff regarding cloud and security too, but that's also just some more code and if-checks here and there....
So is that all in our tech world? Frontend-backend-api-cloud , and you got yourself an online product?
Who is really having the fun in all this? I think the content creators are somewhat happy, like am not a youtube dev but i guess youtube content creators seems very happy and with the shine of enthusiasm in each of their videos. Although now that i think of , they are also most of the times faking it as their happiness depends on income and their income depends on every view they get.
I guess then the top guys would be happy and enjoying, as the product's growth increases their income, but they seems to have even more sulking faces than us devs
Ok, Fuck happiness. Are you guys jobs also as monotonous as mine?6
Early 1970s, when I was around 8 years old. I read about Artificial Intelligence and it blew me away. I knew nothing about computers, other than I wanted to program them.
I still have old computer magazines, starting from around 1978 not long after the microcomputer revolution started.
My first computer had 2K RAM. That's 2048 bytes. I expanded the memory 1K at a time, and it took 2 chips - they were 4 bits by 1024 so you needed 2 chips to have 8 bit wide memory.
2114 static ram, 300ns.
I think they still make them!6
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
(Warning: This rant includes nonsense, nightposting, unstructured thoughts, a dissenting opinion, and a purposeless, stupid joke in the beginning. Reader discretion is advised.)
honestly the whole "ARM solves every x86 problem!" thing doesn't seem to work out in my head:
- Not all ARM chips are the same, nor are they perfectly compatible with each other. This could lead to issues for consumers, for developers or both. There are toolchains that work with almost all of them... though endianness is still an issue, and you KNOW there's not gonna be an enforced standard. (These toolchains also don't do the best job on optimization.)
- ARM has a lot of interesting features. Not a lot of them have been rigorously checked for security, as they aren't as common as x86 CPUs. That's a nightmare on its own.
- ARM or Thumb? I can already see some large company is going to INSIST AND ENFORCE everything used internally to 100% be a specific mode for some bullshit reason. That's already not fun on a higher level, i.e. what software can be used for dev work, etc.
- Backwards compatibility. Most companies either over-embrace change and nothing is guaranteed to work at any given time, or become so set in their ways they're still pulling Amigas and 386 machines out of their teeth to this day. The latter seems to be a larger portion of companies from what I see when people have issues working with said company, so x86 carryover is going to be required that is both relatively flawless AND fairly fast, which isn't really doable.
- The awkward adjustment period. Dear fuck, if you thought early UEFI and GPT implementations were rough, how do you think changing the hardware model will go? We don't even have a standard for the new model yet! What will we keep? What will we replace? What ARM version will we use? All the hardware we use is so dependent on knowing exactly what other hardware will do that changing out the processor has a high likelihood of not being enough.
I'm just waiting for another clusterfuck of multiple non-standard branching sets of PCs to happen over this. I know it has a decent chance of happening, we can't follow standards very well even now, and it's been 30+ years since they were widely accepted.5
A few days ago I decided to install Windows 7 on a VM (bad idea as it turned out). All fine and dandy and I ran Windows Update a few times to get it at least as up-to-date as it'll get.
I noticed that out of the 4GB RAM I had allocated, an svchost process responsible for the updates was gobbling up all the available memory, just leaving 82MB for everything else. The process itself was as you might imagine consuming over 3GB RAM just for itself. That's how an OS should work right after installation, I'm sure you'll agree.
So I complained about it. Haven't used Windows anywhere for a while so I wasn't used anymore to this level of efficiency. Disk activity went through the roof, though to be fair the underlying disk wasn't an SSD (qcow2 on ZFS on a spinning drive). RAM consumption is something I already covered. CPU temperature shot up to 95C.
So as any idiot would do, I disabled the service related to that process (the svchost process for wuauserv) and the problem went away. But I complained of course, saying that such amazing system utilization metrics wasn't something I expected. I mean for 4GB allocated, having as much as 82MB usable to get stuff done with! 95C on the CPU, on a lot of chips that's the junction temperature! Absolutely beautiful.
When I complained I heard that I had to replace the thermal grease. I do that twice a year. I wrote a custom fan driver for my system that works absolutely great. It was obviously shit. I must be a horrible sysadmin for solving a problem by eliminating the cause, and companies hiring me must be ashamed of themselves. My hardware must be shit (that's a common one with Windows users) despite being a business laptop and the guest system being a VM. Oh and I'm an idiot of course for complaining about such amazing system metrics in Windows.
I love Windows and its community...8
Not Dev related but I'm super fucking excited and have to vent somewhere and fuck Facebook and Twitter.
Purchased a smoke infuser and just ordered some hickory and applewood chips... As soon as this shows up I'm going to be infusing every single item in my kitchen!
Got a feeling cooking is going to start taking away valuable Dev time!2
Holy fuck AMD really have made a comeback... NVIDIA is admitting they lost (how I interpret this, no flame) and then we have Intel literally running their already fragmented CPU range into a ditch of mismatched specs and just brute forcing higher cord counts on an almost out of date manufacturing process...
And now AMD is also releasing new mobile chipsets with integrated Vega graphics (on the zen based chips) that are already outperforming the closest Intel competitor on thermal and raw performance...
What the fuck!!!
AMD might actually become Intel and NVIDIA rolled into one the way they are going in my eyes...13
I'm part of a robotics team in my highschool. We work on autonomous robots, which are driven with microcontrollers like the Arduino and "bare" Atmel chips.
Last year we were using a protocol called CAN. CAN is a bus which runs at 1Mbps and it is quite easy to connect devices together. (It's a bus ofc it is). BUT... it needs a terminator at the end, mostly 120 ohm.
Every year we are on a deadline and something broke on our current board and we needed to solder up a new one, but we couldn't find the 120 ohm terminator... ANYWHERE!
At end after searching for it in the workshop for 4h straight (12am- 4am) we finally found it, and soldered up the new board and guess what... it wasn't what we thought, the code was the problem.
After realizing the problem my teammate and I, in silence just stood up, packed our things and went home. Argh!2
Just set up my own IoT device for free thanks to the guys at Losant.
I met them at codestock a couple years ago. They were running a workshop with some Adafruit boards and at the time I had never seen anything like Arduinos before. I was fascinated. So I walked up and asked about it. They said they sold the chips just to demo their IoT stuff. I said I'd buy one. I then waited like 40 minutes for them to get their card reader working. They gave up and handed it to me, gratis. That started my dive into electronics from programming.
Few years later, I needed a remote temperature sensor to make sure a certain unattended appliance never got below freezing. I suddenly remembered that kit (now buried under my heaping stash of electronics), followed the tutorials, and had the exact thing I needed up and running in like a few hours, with all the bells and whistles I could want. And for free.
The icing on the cake here? I went on their website to look at a kit to replace it. I found one with even more goodies in it, and the entire kit cost less than the cost to go to adafruit and buy just the board alone.
Thanks Losant for being awesome. If you wanna do IoT anything, look em up.
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, might be the first time ever but I have a reasonable client. Oh wait, life isn't that nice!
Boss, stop picking fights over stupid shit with the client!
Boss, actually show up to meetings you called!
Boss, do you want to get us fired from the contract?
Boss, stop threatening the client! They hold all the chips here!
Boss, actually listen to my technical advice since you are not technical!
Boss, go die in a hole!
Boss, I want your job and paycheck you do nothing!
Boss, don't tell me you are tired and we can talk tomorrow when you kept me up until 3am the previous night then called an 8am meeting!
Boss, give everybody, including the client, more than 2 hours notice for a meeting, then get pissed when the client doesnt show. They have other meetings!1
css frameworks are a sign your ui/ux team is an empty bag of chips.
vuetify examples look like toys in their docs and work that way in prod. if you put any two vuetify components together on a page you basically dont have a website anymore. mx px are indicators that your styling abstraction is so bad that adding 8 resize shims to every single node on the dom is the correct solution to your visual spacing dilemma.
css offers so many powerful tools out of the box now, and it takes like a week to actually learn them. instead, we cloak all the functionality and expressiveness of modern css in black-box m a t e r i a l d e s i g n and pretend like obtuse blobs are a viable substitute for coherent, accessible, user-friendly ux.6
So guys you all remember or know or will know how it is to be a student. Not that much money around, have to be responsible for the first time of your life and I don't know since we're all programmers here our Desktop/laptop that we invested our money on for the university is our life.
Recently I have found out that something is up with my laptop. My Ram should have been 8GB but it shows only 4. I almost fainted, I thought the seller caught an idiot (me) and sold it like that. So I decide, for some reason, to buy 2x8gb ram so I can have 16 since its the max support of the system.
I open the laptop and what to see but my laptop had 2x4gb in there.
Regardless I installed the new ones to find out what else but my PC is now showing just 8gb.
"Calm down Nick" I said maybe GPU uses it but no it only shows 4gb ram, the same amount the laptop came with so I guess it's integrated.
So now I can only think that the problem is occurred because my Father, dropped the laptop when I specifically told him to not have it in dangerous high places. I Googled around but everyone is talking just swaping the ram chips well yeah I did that 100 times, still the same.
Tl;Dr I'm freaking out because theres something up with my laptop9
First off i'll try and describe my game in as little words as possible, think your typical survival game but crossed-over with a town management/village management game and in VR.
So this is a little old since i posted it on twitter a couple weeks back but I made some progress on a game i'm working on.
Sorry that it's a link to twitter for those that do not like twitter, i can give you a run-down of what it shows and ill figure out a way of linking the videos somehow.
I decided that I should show some progress on the game I started working on before I joined the company that I'm with now, my only issue is the amount of free time I don't have to work on it.
First video shows resource gathering, we (as in me and my brother) wanted to go with more realistic tree chopping something you would see in the forest or stranded deep, you chop a tree at the base and it will fall down, where you then can chop it into logs and planks.
The next video shows the blueprint system which is how you will craft your items like the forge, crafting table, etc. By picking the blueprint from within your book (which doubles for your UI/Menu/way to exit the game) and placing it on the ground. You then take a hammer and hit it in place to confirm the placement - I definitely want to be able to have the object be rotatable and such which i'll do in the future.
Last one shows tool dismantling system, where you can take tools/weapon apart when put on a crafting table, the idea behind this is so you can change up parts of your tool/weapon brcause individual bita will degrade and visually show wear, axe head will show chips that will get bigger and eventually break, which will leave you with just a handle. You can also jusy generally improve one piece of your weapon/tool.
Last thing that I left out as an actual video was that the map generation is all procedurally generated, all thanks to Sebastian Lague's tutorial, I managed to finish it and will definitely be exploring ways to create awesome maps to play on.
Everything is mostly from when I worked on this game in december with a few things that I did recently when I get the chance I will do lots of overhauling and work to making a demo version of the game!
Since I already got fired I don't have problems start uploading my tutorials at the middle of next month...
First... Where should I put them? I'll Make a written tutorial, and Video tutorials, so I need a good cheap web provider and some places like Instructables, but I would like the possibility of gaining some money with some of the stuff.
Btw, Already have one... Maby some can help?
I have an unmounted HDD (3 pins or 4 pins, must work: With no driver and no extras... I know it's possible, just can't find the Information. Then I'll make a video on how to make the same thing with chips (not MCUs) and finally with MCUs). Since there isn't much information around there about this, would be a great 3/4 video tutorial.
I know I can make it work without the board or drivers since I already saw two Indians doing it on youtube, just couldn't understand them and the video quality is shit.
Shit will probably my first Video, but I need to find ways first.
One of the tools I already made: https://youtube.com/watch/...
The problem is using a 300w power supply for tools that require so low power.
I wanted to work on my new project this weekend, Friday I started good with a case of beer, chips and... fell asleep. Saturday I started good as well then breakfast happened and evening ended with shots. Today is sunday and I started fresh with deleting and fixing the drunk code from previous days. 2 screens made and 20 lines of code, pretty good weekend.2
Look... As much as I want to believe this... We all know it won't happen...
The tie between iOS and the in house ARM chips is something you can't replicate with just a new piece of hardware...5
Half of the courses in my Bachelor of Engineering in IT course was about electronics. They even had chemistry and drafting.
What did they think I'll get a job in? Making silicon chips or writing CAD software?
And they didn't put in Algorithms. And combined Java and web development into one course.
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
So I’ve asked my Unis infrastructure guys via mail, why we don’t use the digital id with our phone additional to our RFID Badge.
One of those (maybe a moron, I don’t judge yet, see question below) replies, that they would need to replace all readers “as current ones rely on RFID scanning chips” and they are not sure how US Unis implemented it.
Thing is, that when I hold my iPhone SE 2020 next to the reader, my phone shows my credit card to use for Apple Pay.
Doesn’t that mean, that they use compatible RFID frequencies ?
I’m not an iOS dev, so maybe someone can help me out. Any info appreciated!11
Some user profiles I thought were worth stealing for a post:

'club mate' read: probably white powder and ritalin. I heard he once dismembered a horse and put the bloody head in a rivals bed.

Am currently handling a very bad code, once you add any feature the app crash and you have to fix the whole POKER application ( as you know poker is a really complicated and everything related to each other). The app crash and every single line of code goes wrong. As well i do barely have a break and am working overtime and during the weekend.
In addition to all of this i have a very complicated design and animation to the chips. Adding to this am the only developer working on this project.
Summing-up am working 10 to 11 hours per day 7 days a week. And still the manager is dissing me as if am not a good developer.
I feel so bad, i cant describe how am currently feeling.
So guys do you believe handling a very bad code might reflect your coding skills ?3
I read the other day that tech companies are trying and failing to make chips smaller and faster by reducing transistor size.
Yet Apple does this with ease. You know how?
They remove or REDUCE the number of transistors to make it smaller.2
What does everyone keep on their desk? I have a rubber ducky for debugging, Google glasses for days I want to threaten to leave, and a few poker chips to play with when I need to think.1
Finally accepted as telematics lab. assistant
Had to go to 30 years old initiation tradition by drinking 'The Drink' before getting lab. full access
Full Recipe: Mineral water, instant coffee, vanilla milk, cola, banana, pineapple, apple, melons, cup ramen, peanuts, snickers, m&m, potato chips, nata de coco.
1. Shove it all to blender

I've found that a caramel latte pairs nicely with kettle-cooked bbq potato chips.
Or I'm just weird.2
In my university years I had a computer engineering professor who had an ascent and it sounded like an "S" being added to each word. I went for the first lecture and not knowing if I was at the right room I left after hearing:
"Togethers we wills do projects with some chips"
I was like ... thanks I just had breakfast!
How the fuck am I supposed to go on learning embedded programming, when almost all chips/parts take at least 2 months to ship...
This will take ages 🙃6
Woo time for a Chromebook rant against Samsung!
So they just 'revised' the Chromebook plus (Currently using v1 to write this) and I was intrigued because they ditched the Samsung made ARM chips for an intel CPU.... Buuuuuuuuuut... It's a fucking celeron... Of all fucking things to put in a half thousand dollar laptop, at least an m3 would be useful. Then I find out they are ditching the full metal body, it's heavier, thicker, same 3GB of RAM, ditching the 3:2 aspect ratio (Fucking why?!) and the 'upgraded' keyboard doesn't even have back lighting...
Ugh, makes me want a pixel book more, double the price and a million times the performance and quality -.-5
I just got hired at a small MSP and I’m just utterly fucking frustrated by the shitty tools and complete lack of client documentation. I want to implement tons of FOSS tools for these newbhats but they seem to like spending money on tools that only work half-assedly at best... looking at you LogMeIn!
I’ve setup Apache Guacamole a few times before and want to get each client a guac-srv setup for client’s server mgmt. or PowerShell Web Access for clients.
I want to build AWS infrastructure for clients cause we can use cloudformation or terraform to build infrastructure. But these skunk-taint licking dipsticks would rather support physical 2003 servers. If I didn’t need this job to pay my bills right now I’d be fucking gone.
But... they are very nice people.
Just technologically speaking, they eat lead paint chips for breakfast and like to piss on electric fences for the funsies.
Are AMD chips now on par, better then Intel's now?
About 10yrs, Intel beat AMD hands down. My dad bought an AMD quad core around then but the performance was probably no better and an INTC 2-core if I remember.
After that I always bought Intel i7s.
But now wondering has AMD caught up?11
Any gift recommendations. My birthday comes up in a few days and he asked what I wanted as a birthday gift(gifts are supposed to suprises but being able to choose is good still).
However I cannot ask for electronic gadgets. That knocks a lot of stuff of. The exception is that if something does not make me spend more time on the computer that is allowed. Kinda weird. For example I can ask for a printer or medical equipment like oximeters since that wont make me spend more time on the computer. Both of these examples were given by my father. I could ask for a new printer however we still have a printer but it is currently in the shop since it is not being used and the shops printer broke and is hell to replace since they need chips to verify toners and you need to get those chips separately from what my father told me and the shops printer should be repaired in a few months since lockdown was lifted a few days ago and I won't need to print something since everything is online and they don't need to show student projects yet.
Thia knocks a lot of hardware off since by definition if I am using hardware I still need to code it to do something which is more time on computer which is not allowed. So no fiddling with aurdino or rasberry pie or whatever is the most used hardware kit.
I can buy some course or a book to learn something but I already have problems with consistently learning c# with a good book which will lose value in November and that most topics I would like to learn like computer networking or some new language are practical which is more time on computer which is not allowed.
So the only thing I can buy are some books to enjoy reading for fun or some school books like a science digest book like Together with or the ultra popular maths reference book RD Sharma
So what things should I ask which comply with the rules my father has laid or just skip this thing1
• 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.
