Random fact #0

Back in the days of SEGA Saturn, SEGA was really picky in terms of the game stability. All the games that we're about to be released had to pass a series of tests, like for instance they had to run for almost a week without any crash non stop on a real hardware, or withstand cartridge tilting. If it failed, SEGA wouldn't license it and developer had to fix the bugs and re-send it again.

To fool SEGA testers, game devs we're adding exception screens with the fake "hidden content". Like in Sonic 3D Blast, it presented a screen in the image below and then the level select screen.

So yeah, it's not a bug - it's a feature

Most of the code I write nowadays is for GPUs using a dialect of C. Anyways, due to the hardware of GPUs there is no convenient debugger and you can't just print to console neither.
Most bugs are solved staring at the code and using pen and paper.

I guess one could call that a quirk.

I have this little hobby project going on for a while now, and I thought it's worth sharing. Now at first blush this might seem like just another screenshot with neofetch.. but this thing has quite the story to tell. This laptop is no less than 17 years old.

So, a Compaq nx7010, a business laptop from 2004. It has had plenty of software and hardware mods alike. Let's start with the software.

It's running run-off-the-mill Debian 9, with a custom kernel. The reason why it's running that version of Debian is because of bugs in the network driver (ipw2200) in Debian 10, causing it to disconnect after a day or so. Less of an issue in Debian 9, and seemingly fixed by upgrading the kernel to a custom one. And the kernel is actually one of the things where you can save heaps of space when you do it yourself. The kernel package itself is 8.4MB for this one. The headers are 7.4MB. The stock kernels on the other hand (4.19 at downstream revisions 9, 10 and 13) took up a whole GB of space combined. That is how much I've been able to remove, even from headless systems. The stock kernels are incredibly bloated for what they are.

Other than that, most of the data storage is done through NFS over WiFi, which is actually faster than what is inside this laptop (a CF card which I will get to later).

Now let's talk hardware. And at age 17, you can imagine that it has seen quite a bit of maintenance there. The easiest mod is probably the flash mod. These old laptops use IDE for storage rather than SATA. Now the nice thing about IDE is that it actually lives on to this very day, in CF cards. The pinout is exactly the same. So you can use passive IDE-CF adapters and plug in a CF card. Easy!

The next thing I want to talk about is the battery. And um.. why that one is a bad idea to mod. Finding replacements for such old hardware.. good luck with that. So your other option is something called recelling, where you disassemble the battery and, well, replace the cells. The problem is that those battery packs are built like tanks and the disassembly will likely result in a broken battery housing (which you'll still need). Also the controllers inside those battery packs are either too smart or too stupid to play nicely with new cells. On that laptop at least, the new cells still had a perceived capacity of the old ones, while obviously the voltage on the cells themselves didn't change at all. The laptop thought the batteries were done for, despite still being chock full of juice. Then I tried to recalibrate them in the BIOS and fried the battery controller. Do not try to recell the battery, unless you have a spare already. The controllers and battery housings are complete and utter dogshit.

Next up is the display backlight. Originally this laptop used to use a CCFL backlight, which is a tiny tube that is driven at around 2000 volts. To its controller go either 7, 6, 4 or 3 wires, which are all related and I will get to. Signs of it dying are redshift, and eventually it going out until you close the lid and open it up again. The reason for it is that the voltage required to keep that CCFL "excited" rises over time, beyond what the controller can do.

So, 7-pin configuration is 2x VCC (12V), 2x enable (on or off), 1x adjust (analog brightness), and 2x ground. 6-pin gets rid of 1 enable line. Those are the configurations you'll find in CCFL. Then came LED lighting which required much less power to run. So the 4-pin configuration gets rid of a VCC and a ground line. And finally you have the 3-pin configuration which gets rid of the adjust line, and you can just short it to the enable line.

There are some other mods but I'm running out of characters. Why am I telling you all this? The reason is that this laptop doesn't feel any different to use than the ThinkPad x220 and IdeaPad Y700 I have on my desk (with 6c12t, 32G of RAM, ~1TB of SSDs and 2TB HDDs). A hefty setup compared to a very dated one, yet they feel the same. It can do web browsing, I can chat on Telegram with it, and I can do programming on it. So, if you're looking for a hobby project, maybe some kind of restrictions on your hardware to spark that creativity that makes code better, I can highly recommend it. I think I'm almost done with this project, and it was heaps of fun :D

I am working on my passion project, on my own vacation days because my advisor did not approve it and I can't take no for an answer.
But I had 3 amazing days working with my friend and research partner, full of stupid bugs, moody hardware and a lot of nutella-covered food.
I think I am going to document some of the progress on Twitter, because it supports uploading videos. If anyone is interested in failing robots, I can share the link/handle :)

Apple products are fucking trash, I don't give a shit if you have money to waste, but don't fucking brag about how superior your 3000$ excuse of a fucking laptop is the best laptop in the world when you could easily afford a desktop with 2 1080 GTX in SLI for that price.

"but mac has lyk no bugs, its so good"

NO FUCKING SHIT, THE OS IS BUILT WITH THE HARDWARE USED IN MIND. THEY DON'T BUILD 500000 MODELS OF MACBOOKS, THEY JUST HAVE TO MAKE ONE MODEL WORK, AND ALL OTHER LAPTOPS WHO HAVE THE SAME HARDWARE WILL.

This is fucking ridiculous.

That's like designing a site, but only for Firefox because that's the browser you use and you expect everybody to use that browser. Obviously it'll work fine on your machine.

I am so fucking sick of Apple fan boys.
I am fully aware some of you devranters are apple fans, but this has been something I've wanted to say for ages, albeit i'm a little late to the party.

Stop wasting money on overpriced trash.

Two years ago: company exec (Mac fan) buys a Surface Pro to show off our .NET application to customers as he travels. Hands it to me (I build releases) and I iron out a few Win 8 bugs since we'd always used Win 7 before. Get it set up, get to like the device a little, he takes it home... and returns it within 24 hours because he didn't mesh well with Windows. (Again, Mac user.)

8 months later he buys a Surface Pro again. I install our latest release, verify that everything is working as expected with hardware we normally don't use, and give him a controlled setup that will just work when he's at a customer site. Once again, he returns the Surface within 24 hours because he can't get used to Windows.

At least we verified Windows 8 compatibility, I guess.

So I just found out that my colleague who I often have to work with does not use a debugger to troubleshoot any bugs at all. Actually, he does not even run or test his code locally either with prints or something similar. He just commits java code directly on bitbucket, no source control, without making sure it compiles and then he runs a CI provided by devops that takes 4 freaking hours to run because he bloated that shit up somehow.

I suggested politely to help him find a more efficient approach and to use my hardware setups for speeding up his work because I assume it must be pretty painful to work with, but he just refused.

That and those "seniors" with 10 years Linux development XP in the embedded field who don't know basic commands like ls, cat and touch and code in notepad.

Fucking me, who the hell am I working with and can someone please end me?

3 hours making this beautiful circuit to test stepper motors.
Arduino nano + L293D + pot
Fucking bitch has a short circuit somewhere and can't find it out...
Made the same project in a breadboard in 15 minutes and it's working.
Fuck hardware bugs.
Cutted in the middle of all connections, took out excess solder... Nothing.
Fuck it, moving to the next ideia

Hey guys.
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 cool

1) Built an entire SoC around a MIPS CPU. Fixed bugs in the CPU. Created hardware, busses, firmware, wrote Linux drivers, ported Linux.

2) Still working on a C++ abstraction framework for heterogenous computations for 4 years. About to solve / create a prototype for GPGPU and maybe even HDL code generation. Utilizes dynamic dispatch for scalar, SSE, AVX and other targets. I started this only because I did not like the performance of procedural noise algorithms utilized in a game prototype I started in 2015.

3) Created a game in 5 months to drag myself out of depression. Feeling success while your job sucks is soooo goooodd...

I started to hate programming.
I started with a lot of enthusiasm 11 years ago up to become in 2 years a full stack dev, a sysadmin and had also my fair share of technical assistance on every device plus hardware experience mounting hardware like cctvs, routers, extenders, industrial printers and so on. At the time you actually had the tools to solve problems and had to crack your head and pull hairs to solve stuff and people actually was developing solution and frameworks that solved stuff.

Today I can't stand anything.

Every midschooler feels entitled to release a framework that is announed as the next cure for cancer. Web dev once was thin and simplistic, now simplicity is considered a bug and not a feature.
I'm working on an angular project for the nth time and the whole environment is a clusterfuck of problems held togheter with kids glue.
Someone did a tool/framework for everything but most of it is barely well tested or mature.

Just to start this project we had to know, beside html/css/js techs like Angular, Kafka, Kubernetes, Docker, git, Lit, npm/node, mysql/sql server, webpack/grunt and the hell that it brings, C#/Asp.NET/MVC/WebAPI, and so on, the list is long.

DAMN. Making a simple page which shows a tabbed view with some grids requires you to know a whole damn stack of technologies that need to cooperate togheter.
It's 10x more complex and I actually find it much less productive than ever.

But what bugs me most, is that 90% of that stuff is bug ridden, has some niche use case or hidden pitfall and stuff because with this whole crap of "hey we put on github you open a ticket" they just release spaghetti code and wait for people to do the debug for them.

Angular puts out a version every 2 days and create destructive updates.

I am so tired that I spend most of my 8hrs binging youtube vids in despair to procrastinate work.
I liked to do this once....

So I enventually spent 2 years working for that company with a strong b2b market. Everything from the checkouts in their 6 b2c stores to the softwares used by the 30-people sales team was dependant on the main ERP shit home-built with this monstruosity we call Windev here in France. If you don't know it just google and have some laugh : this is a proprieteray FRENCH language. Not french like made by french people, well that too, but mostly french like the fucking language is un fucking french ! Instructions are on french, everything. Hey that's my natural language okay, but for code, really ?

The php website was using the ERP database too, even all the software/hardware of the massive logistic installation they had (like a tiny Amazon depot), and of course the emails of all employees. Everything was just handled by this unique shitty and so sloooooow fucking app. When there was to many clients on the website or even too many salespeople connected to the ERP at the same time, every-fuckin-piece of the company was slowing down, and even worse facing critical bugs. So they installed a monitor in the corner of a desk constantly showing the live report page of Google analytics and they started panic attacks everytime it was counting more than 30 sessions on the website. That was at the time fun and sad to observe.

The whole shit was created 12 years ago and is since maintened locally by one unique old-fashion-microsoft dev who also have to maintain all the hardware of all the fucking 150+ people business. You know, when the keyboard of anyone is "broken" cause it's unplugged... That's his job too. The poor guy was totally overstressed on a daily basis and his tech knowledge just saddly losts themeselves somewhere in the way. He was my n+1 in a tech team of 3 people : him, a young and inexperimented so-called "php developer" who was in charge of the website (btw full of security holes I discovered and dealed with when I first arrive at the job), and myself.

The database was a hell of 100+ tables of business and marketing data with a ton of specific logic added on-the-go during years. No consistent data model or naming. No utf8. Fucked up relations that ends with queries long enough to fill books. And that's not all, all the customers passwords was just stored there uncrypted. Several very big companies and administrations were some of these clients. I was insisting on the passwords point litterally all the time, that was an easy security fix and a good start... But no, in two years of discussions on the subject I never achieved to have them focusing on other considerations than "our customers like that we can remind them their password by a simple phone call if they lost it". What. The. Fuck. WHATTHEFUCK!

Eventually I ran myself out of this nightmare. I had a few bad jobs already, and worked on shitty software already. But that one really blows my mind (and motivation for a time too). Happy it's over.

i hate linux like a lot , how do you guys use it

like you guys dont want an advertising ID, how the fuck will advertisers know who you are and what you like?

open source , give me a break, you mean your os devs are soo untrustworthy that you just have to see what they wrote in the code, who does that?

free come on, how poor are you linux people, i mean, quality stuff gets paid for, free stuff just means it's trash

and the linux devs , the aint like real coders they are just hobbysts, making your os in their free time

and who wants to install their own software anyway, on other platforms the company curates restricted software that you can use, and i know you'll say its oppressive but its just customer protection.

and i do want my platform to track everything i do, it only helps them build better stuff for me.

and whenever they decide to outdate my hardware and kill support for it, it only means they care and want me to get the latest tech, how considerate.

wait , i hear you say, there are no bugs in linux, my vendor makes sure my os comes with the latest antivirus software, nothing can break my system.

and just because linux runs on servers and most super computers only shows that common users like you and me are ignored, at least my vendor is not a sellout, and still makes stuff for the masses.

you say freedom i say safety i can sleep safe and sound for am protected nutured under one echosystem of software that i can not leave.

The first filamment for my 3D printer had to end at 4h30 in a 5h30 program. FUCKKKKK
Tryed to replace while pausing the printer, but the fucking merlin doesn't reset the extruder stepper motor, so... when I resumed the print it wouldn't extrude filament, because the position of the extruder was wrong....
Well. At least printer time is cheap... I'll just print all the pieces and leave it until tomorow night printing lol

I really lost my faith in our profession.
A Software&Hardware solution that costs more several 10.000€ is broken after every update.

The Producer even achieves to break untouched features in new releases.
No communication at all. If you report Bugs, they are your fault. The whole system has absolutely no security at all.
It is unsecure by design.

And even if they hear your Bug report you have to pray that they will fix it.
Most if the time you have to wait the whole year for a new release tio get your bugfixes.
But there are also bugs that are untouched for years.

WHY? WE PAY YOU!
I want to cry

Aren't you, software engineer, ashamed of being employed by Apple? How can you work for a company that lives and shit on the heads of millions of fellow developers like a giant tech leech?
Assuming you can find a sounding excuse for yourself, pretending its market's fault and not your shitty greed that lets you work for a company with incredibly malicious product, sales, marketing and support policies, how can you not feel your coders-pride being melted under BILLIONS of complains for whatever shitty product you have delivered for them?
Be it a web service that runs on 1980 servers with still the same stack (cough cough itunesconnect, membercenter, bug tracker, etc etc etc etc) incompatible with vast majority of modern browsers around (google at least sticks a "beta" close to it for a few years, it could work for a few decades for you);
be it your historical incapacity to build web UI;
be it the complete lack of any resemblance of valid documentation and lets not even mention manuals (oh you say that the "status" variable is "the status of the object"? no shit sherlock, thank you and no, a wwdc video is not a manual, i don't wanna hear 3 hours of bullshit to know that stupid workaround to a stupid uikit api you designed) for any API you have developed;
be it the predatory tactics on smaller companies (yeah its capitalism baby, whatever) and bending 90 degrees with giants like Amazon;
be it the closeness (christ, even your bugtracker is closed and we had to come up with openradar to share problems that you would anyway ignore for decades);
be it a desktop ui api that is so old and unmaintained and so shitty, but so shitty, that you made that cancer of electron a de facto standard for mainstream software on macos;
be it a IDE that i am disgusted to even name, xcrap, that has literally millions of complains for the same millions of issues you dont even care to answer to or even less try to justify;
be it that you dont disclose your long term plans and then pretend us to production-test and workaround-fix your shitty non-production ready useless new OS features;
be it that a nervous breakdown on a stupid little guy on the other side of the planet that happens to have paid to you dozens of thousands of euros (in mandatory licences and hardware) to actually let you take an indecent cut out of his revenues cos there is no other choice in a monopoly regime, matter zero to you;
Assuming all of these and much more:
How can you sleep at night with all the screams of the devs you are exploiting whispering in you mind? Are all the money your earn worth?

** As someone already told you elsewhere, HAVE SOME FUCKING PRIDE, shitty people AND WRITE THE FUCKING DOCS AND FIX THE FUCKING BUGS you lazy motherfuckers, your are paid more than 99.99% of people on earth, move your fucking greasy little fingers on that fucking keyboard. **

PT2: why the fuck did you remove the ESC key from your shitty keyboards you fuckshits? is it cos autocomplete is slower than me searching the correct name of a function on stackoverflow and hence ESC key is useless? at least your hardware colleagues had the decency of admitting their error and rolling back some of the uncountable "questionable "hardware design choices (cough cough ...magic mouse... cough golden charging cables not compatible with your own devices.. cough )?

If you call yourself a developer or consider yourself part of the IT world and at the same time complain about software updates (all those dumb windows update rants) then do one of the following:
1- write a multi -million line of code OS that runs on virtually unlimited number of PC configurations and hardware and get the code right the first time with no major bugs, no security vulnerabilities, and a consistently fast and stable performance.

Or...
2- stop calling yourself a dev, or part of the IT world.

If the last 2 options are unreasonable, unachievable, or unfathomable.... Then stop bitching about software updates.

Easy. I was in just 1, but i heard what they were all about. They happened weekly.

This boss mainly ran his hardware renting business. The software for that hardware was often optional, but they developed and sold that as a seperate company with almost the same name.

The guy had no idea what development meant. What it means to test. Everything he knew was hardware, and it just never really clicked. This means that bugs and non linear development cost for a feature were confusing to him to a point that when brought up or conflicting, he would look confused, and walk out the office without another word.

This guy would bust in, usually monday morning and call a "meeting"
They gather in the lunchroom as thats the only place everyone fit, and the guy would go on a 3 hour monologue on god knows what.

It was never positive and always full off complaints and idiotic ideas that the senior developer had to break down until as if talking to a big toddler, on why they do not work.

As a result everyones day started mizzerable, nothing got done. The software package was full of logic flaws. And everyone wanted to quit but didn't have the energy to invest in that.

During that internship 1 guy was fired. In the 2 months he was there he litterally did jack shit. And if he did anything it was the bare minimum, committed broken but compilable, and then wait for revision requests.

Yeah that place was a shitshow. I loved it, but never again.

Ah the fun part of linux. Patching all these hardware specific bugs after installing a new system xD Well at least I got rid of all the visible ones so far.

Electronic companies nowadays are no different than ranchers that force their slaves to earn money to buy new stuff cause people can’t repair old electronics or fix software bugs cause it’s not theirs or it’s not maintained and source code is not existent.

Damn you software and hardware corporations.

You tell everyone that you care about environment, yet you don’t fucking support your software and hardware as long as people use it. When you stop support you don’t make everything open source but keep it on your private repositories as intellectual property and fuck your clients.

Literally all electronics and software should be mandatory made open source to the people who purchased product so they can use it as long as they want not as long as corporate assholes want. This is insane law that is splitting our world and making it burn. If I could fix my laptop in nearby shop I wouldn’t have to purchase new one.

If it won’t change we will end up with <10 corporations that would rule world economy, everyone who will work for those corporations will be rich and happy and everyone else will be poor and unhappy . Mind me if this is not already happening and this planet slowly becomes Elysium movie nightmare.

Stop buying new stuff you stupid people cause this make things worse.

If it won’t change in 10 or so years there will be connected to cloud robots all over the world guarding us and some dick shit rich John Conor kid will hack them to exterminate humans by executing order 66. After that there will be big power outage that will put us into the role of battery and we would be closed in the barrel full of pink shit connected to matrix.

Get me out of here you asshole.

Microsoft announced a new security feature for the Windows operating system.

According to a report of ZDNet: Named "Hardware-Enforced Stack Protection", which allows applications to use the local CPU hardware to protect their code while running inside the CPU's memory. As the name says, it's primary role is to protect the memory-stack (where an app's code is stored during execution).

"Hardware-Enforced Stack Protection" works by enforcing strict management of the memory stack through the use of a combination between modern CPU hardware and Shadow Stacks (refers to a copies of a program's intended execution).

The new "Hardware-Enforced Stack Protection" feature plans to use the hardware-based security features in modern CPUs to keep a copy of the app's shadow stack (intended code execution flow) in a hardware-secured environment.

Microsoft says that this will prevent malware from hijacking an app's code by exploiting common memory bugs such as stack buffer overflows, dangling pointers, or uninitialized variables which could allow attackers to hijack an app's normal code execution flow. Any modifications that don't match the shadow stacks are ignored, effectively shutting down any exploit attempts.

Guys please tell me a good linux distro ? Which provides the most suite suiteable dev env and I can play on all linux stuff there as well? I'm new to linux have tried elementry os didn't liked it was full of bugs.
Have just started installing ubuntu and its setup is crashing on my machine.. I have core i3 dell inspiron don't know if os's setp are causing issue or this laptop's hardware sucks
