In my college days i was designing a bootloader for avr microcontroller , i had the idea to flash code wirelessly to avr over bluetooth and also cross compile the compiler for android device so that you can code on android, every thing went well just one thing didn't, i saw that code of certain size is executing properly , greater than that size gives me wired outputs so i have to dump hex from the avr (that is flashed the by bootloader) and compaire it with the original hex of code it got messy as you can see, most fun part of this bug is that error can be anywhere cross compiler may be fucked up , the bootloader may be fucked up , or it may be my bluetooth module , after 14 hours of staring at the hex code i figured out the mess in bootloader instruction that was changing the page address for flashing .
when it worked it was 3am in night i literally burst into tears of joy next day bought myself a cake to celebrate6 -
Although I love developing I always thought that there was something missing.
I learned Java but didn't really like it. I had spent quite some time with web development and enjoyed it but I felt like developing with JavaScript was too high level and I felt the same for Python.
So I started learning the most awesome programming language: C
I just love that I have so much control over everything and that the language is so compact and gives you just the right amount of tools you need.
I also love physics and electronics a lot and it feels awesome to first build something and then program it.
I am looking forward to design a PCB (printed circuit board) and write code for an AVR microcontroller like the Atmega328 (most arduinos use this one).
Picture of the project I am working on.10 -
How Microsoft devs think about Linux 😁.
This was found inside the index.html of Visual Studio Code editor.9 -
WHY AM I SO FUCKING AWKWARD OH MY LORD! LITERALLY ALL I HAD TO DO WAS WATCH A SCHOOL PLAY AND THEN GET A PICTURE WITH A CAST MEMBER AND IT WAS PROBABLY ONE OF THE FEELINGS I'VE HAD IN THE PAST WEEK! GOD FUCKING DAMMIT I AM SO DONE WITH THIS! I'M TIRED OF BEING SO AWKWARD AND ANXIOUS! I DON'T GET HOW PEOPLE CAN DO ANYTHING LIKE THAT WITHOUT FEELING UNCOMFORTABLE. THIS HAS LITERALLY RUINED MY FUCKING LIFE AND I'M SO TIRED OF IT. I KNOW PEOPLE LIKE ME BUT I JUST CAN'T GET MYSELF TO TALK TO ANYONE! THE SIMPLEST THINGS TAKE SO MUCH OUT OF ME AND I'M SICK OF IT! I'M JUST TIRED OF IT! I'm just, tired.8

A kid in highschool asked what are the similarities between Java and Javascript. I told him:
"Java is to JavaScript what Car is to Carpet."6 -
Never worked before so I'll talk about one of the former staff at my school.
This guy worked as IT and did some teaching in the high school. Early last year, he suddenly disappears for no reason.
Now, I'm going to go in order of what we (the students) found out, not, chronological order.
Firstly, turns out that in class he would make comments about female students. Nothing explicit, just kinda strange. I forget the examples I heard but think like the overly friendly old guy. Those types of comments from a 40-something IT guy. (Some female students knew about this for a long while but I only heard about it after the investigation)
Next, rumor got out that they found some stuff on his computer. I don't know how, but it turned out to be accurate, and we were accurate at the follow-up assumption that it was porn.
After that, the school made an announcement that we had been arrested. Up until then, we just assumed he had been sacked. He was weird sure, but we didn't think criminal.
Some other students looked into the police records, and it turns out this guy had been arrested for possession and distribution of child pornography.
Pretty sick right? Its worth pointing out now that our school has Pre-K through 12th grade students.
I gained a new level of respect for my female classmates after that. I didn't even know that was going on, really wish I could have helped out.1 -

I fucking HATE the Arduino environment right now.
First of all: you can't fucking put your project files in a sub folder to the main file. I can't write #include "src/motor.hpp" because it doesn't fucking know what that means.
Turns out you have to put all your header files in the fucking library folder common for all Arduino projects!
Secondly, you can't call your cpp headers hpp, they HAVE to be called h, or the Arduino environment throws a fit and begins whining about being unable to find the fucking files.
Not just that! You can't reference other Arduino libraries from within your library because the environment doesn't know what that means either.
To get around that you need to fucking include the library in your main file, AND THEN you can include it in the library file that uses it. After all, it should be the programmer's job to soon feed a so called IDE, right?
I'M SO FUCKING DONE WITH THIS SHIT! 😤
I'm ready to either program the Arduino directly with an AVR programmer or even port the entire project to the raspberry pi where I have a proper fucking Linux environment with a proper fucking directory structure so I can code proper fucking C++.
Hell I'm even fucking willing to spend all weekend porting all the code myself if necessary.
It's not reasonable that correct fucking C++ code is invalidated because I called the files something "wrong" and put them in the "wrong" directory.

"user friendly project board" my ass12 -
I'm a young dev with ADD. Basically I just need to stay up late, and then get myself to hyperfocus on my code. It typically gets done in time to get a decent night's sleep.1

#Apple #FaceID
Yet another step towards the God's eye in Fast & Furious. Since it requires a 360 scan of a face, CIA just requires a photo to find anyone in the planet who's using an iPhone X [Stands for Expensive]. There's a reason why Apple ditched the fingerprint sensor.
RIP #Privacy 😶5 -
Given the recent election, I'm taking measures to ensure the privacy and security of my data. Call me paranoid, but I think the NSA is going to be getting some extra funding soon. I'm already working on encrypting a ton of my data. Any other tips some of you guys could give me?8

So I want to build myself a custom buttonbox for star citizen and warthunder, my hotas really doesn't have enough or fittingly placed buttons for either of those games. What would be the best approach for this?
My first thought was to take an arduino or some AVR chip on an USB connection and write a custom JoyStick driver but that would be a major pain on the buttocks.
Also would I buy an Arduino or go full custom stuff and buy some chip from TI and DIY the board completly?
On the other hand if I'm gonna tinker with stuff on my own time I propably should pick up an ARM processor so I get familiar with the architecture, but that's propably overkill.
But 8-bit AVR is so constrained so maybe if I want to expand and create something like an MFD the poor 8266 would propably just go up in flames.
Has anybody a better idea or knows some ready to rock board for this kinda stuff? Best case scenario with a Joystick driver or something?8 -
~They said~
Why don't we write code that runs in parallel on AVR, and yeah, keep it simple, we don't want complexity.
*Me*
:/ :| -
Good guy Google.
Recently started a new job. Getting good feedback on my work. When really everything is off google :D -
Trying to do an LFS build on a computer that keeps restarting. Need to mount the partitions and export variables all over again (ノ=Д=)ノ┻━┻1

Putting my draw_char routine in a for loop breaks everything... Doesn't when I just sequentially call it... Only when called from a for loop...
-
Let's list off all the craziest stuff that happened in 2016. (Crazy meaning unexpected not good or bad)
I'll start with the cubs winning the world series.6 -
Tried (and still trying) to do an LFS build. I already worked with Ubuntu, Debian, and Arch, but somehow a successful build eludes me. Each time I follow the book as closely and possible, but each time I got different issues. I've had to format the partition I'm working on at least 20 times now. Its fun, but I have no idea how I manage to mess up in so many ways.

Trying to write a program a la `man` in ncurses and just, is this hell?
I just want a floating header, a scrollable main body that reads from a file, and a command line footer, why is that so difficult? I finally got it to handle resizing terminals but now I need to try to compile it for windows, which does have unofficial ports of ncurses, but I have no idea how to use them.
Should I just restrict the windows version to a non-interactive command instead of a TUI like I want?2 -
So I was working on Nex Robotics's Firebird V,
Was doing some graph traversal thing...
And was breaking my head for 28hrs... I was passing the bot an structure of direction and no. Of times it had to take that direction...
something like for(int i=0; i<dir.times;i++)
And after 29 hrs I realized it also had negative values...
that effing abs() was missing 😫4 -
Oh... I dont know what to pick...
So i will pick 3 projects from my 3 stages of my dev "carrier"
1.Right after i discovered programing and learned how ,if, while and similar structures worked. The launguage was object pascal with delphi 2007
That was a "safe" with a stupidly complicated lock (text inputs, sliders, ect) it opened a secret folder in the end.
2. It was a embedded code for a Atmega8 AVR, Atmel studio, pure C but without memory managment (i didnt even know that it even existed)
It was a Pip boy knockoff, 16x2 display and a small keyboard connected to the arduino like board that i made on a proto board.
It wasnt that much of a pipboy, it was more of a showoff of atmega8 internal systems, (ADC, timers, interrupts and such)
3.DataLab, after helping my friend with his master thesis, (we meet on discord long story, i was in high school) i decided that mathlab is shit and i created a visual scripting enviroment, launguage C# .net 4 (in the latest version)
I remade the whole program from scrach 1 time, significantly improving everything (code reuse, better algorithms, data processing, code redability and edge cases) I have learned good practises from everywhere. I learned how to use git.
DataLab project looks just like LabViev (i didnt notice that it even existed...), it is frozen now because of my mental status but im planning on using it on my CV when i will be looking for jobs on holidays. There are many things that i can improve in that program but ... first i have to fix myself. -
Per my previous rant, I'm reading the reviews for different UPS units 800+ VA/400W) and am looking at this one particularly after going through a lot of them but they all seem sort of mixed.
https://amazon.com/dp/B000QZ3UG0/...
Lots of failures, burning smell, Sparks, and not honoring damages or that they can actually destroy the PC rather than helping it....
And for this brand, another issues send to he AVR vs PFC... Don't know which to get except PFC is $20 more...
I just don't know anymore, sorta like I'm screwed if I do and screwed if I don't...
How do you pick which UPS to buy and make sure it doesn't burn the house down?4
