Was helping somebody with a little C++ issue (disclaimer: I know jackshit about C++).
After a while off reading his code and opening a file called "pi.cpp", I noticed something odd...

This guy literally thought is was a good idea to put 81663 fucking decimals of pi in a #define statement :^)

On the screenshot, that weird "noise" on the right is actually a scrollbar of the code itself...

It finally hit me the other day.
I'm working on an IoT project for a late-stage ALS patient. The setup is that he has a tablet he controls with his eye movements, and he wants to be able to control furnishings in his room without relying on anyone else.
I set up a socket connection between his tablet and the Raspberry Pi. From there it was a simple matter of using GPIO to turn a lamp or fan on or off. I did the whole thing in C, even the socket programming on the Pi.
As I was finishing up the main control of the program on the Pi I realized that I need to be more certain of this than anything I've ever done before.
If something breaks, the client may be forced to go days without being able to turn his room light on, or his fan off.
Understand he is totally trapped in his own body so it's not like he can simply turn the fan off. The nursing staff are not particularly helpful and his wife is tied up a lot with work and their two small children so she can't spend all day every day doting on him.
Think of how annoying it is when you're trying to sleep and someone turns the light on in your room; now imagine you can't turn it off yourself, and it would take you about twenty minutes to tell someone to turn it off -- that is once you get their attention, again without being able to move any part of your body except your eyes.
As programmers and devs, it's a skill to do thorough testing and iron-out all the bugs. It is an entirely different experience when your client will be depending on what you're doing to drastically improve his quality of life, by being able to control his comfort level directly without relying on others -- that is, to do the simplest of tasks that we all take for granted.
Giving this man some independence back to his life is a huge honor; however, it carries the burden of knowing that I need to be damned confident in what I am doing, and that I have designed the system to recover from any catastrophe as quickly as possible.

In case you were wondering how I did it all: The Pi launches a wrapper for the socket connection on boot.
The wrapper launches the actual socket connection in a child process, then waits for it to exit. When the socket connection exits, the wrapper analyzes the cause for the exit.
If the socket connection exited safely -- by passing a special command from the tablet to the Pi -- then the wrapper exits the main function, which allows updating the Pi. If the socket connection exited unexpectedly, then the Pi reboots automatically -- which is the fastest way to return functionality and to safeguard against any resource leaks.
The socket program itself launches its own child process, which is an executable on the Pi. The data sent by the tablet is the name of the executable on the Pi. This allows a dynamic number of programs that can be controlled from the tablet, without having to reprogram the Pi, except for loding the executable onto it. If this child of the socket program fails, it will not disrupt its parent process, which is the socket program itself.

3 rants for the price of 1, isn't that a great deal!

1. HP, you braindead fucking morons!!!

So recently I disassembled this HP laptop of mine to unfuck it at the hardware level. Some issues with the hinge that I had to solve. So I had to disassemble not only the bottom of the laptop but also the display panel itself. Turns out that HP - being the certified enganeers they are - made the following fuckups, with probably many more that I didn't even notice yet.

- They used fucking glue to ensure that the bottom of the display frame stays connected to the panel. Cheap solution to what should've been "MAKE A FUCKING DECENT FRAME?!" but a royal pain in the ass to disassemble. Luckily I was careful and didn't damage the panel, but the chance of that happening was most certainly nonzero.
- They connected the ribbon cables for the keyboard in such a way that you have to reach all the way into the spacing between the keyboard and the motherboard to connect the bloody things. And some extra spacing on the ribbon cables to enable servicing with some room for actually connecting the bloody things easily.. as Carlos Mantos would say it - M-m-M, nonoNO!!!
- Oh and let's not forget an old flaw that I noticed ages ago in this turd. The CPU goes straight to 70°C during boot-up but turning on the fan.. again, M-m-M, nonoNO!!! Let's just get the bloody thing to overheat, freeze completely and force the user to power cycle the machine, right? That's gonna be a great way to make them satisfied, RIGHT?! NO MOTHERFUCKERS, AND I WILL DISCONNECT THE DATA LINES OF THIS FUCKING THING TO MAKE IT SPIN ALL THE TIME, AS IT SHOULD!!! Certified fucking braindead abominations of engineers!!!

Oh and not only that, this laptop is outperformed by a Raspberry Pi 3B in performance, thermals, price and product quality.. A FUCKING SINGLE BOARD COMPUTER!!! Isn't that a great joke. Someone here mentioned earlier that HP and Acer seem to have been competing for a long time to make the shittiest products possible, and boy they fucking do. If there's anything that makes both of those shitcompanies remarkable, that'd be it.

2. If I want to conduct a pentest, I don't want to have to relearn the bloody tool!

Recently I did a Burp Suite test to see how the devRant web app logs in, but due to my Burp Suite being the community edition, I couldn't save it. Fucking amazing, thanks PortSwigger! And I couldn't recreate the results anymore due to what I think is a change in the web app. But I'll get back to that later.

So I fired up bettercap (which works at lower network layers and can conduct ARP poisoning and DNS cache poisoning) with the intent to ARP poison my phone and get the results straight from the devRant Android app. I haven't used this tool since around 2017 due to the fact that I kinda lost interest in offensive security. When I fired it up again a few days ago in my PTbox (which is a VM somewhere else on the network) and today again in my newly recovered HP laptop, I noticed that both hosts now have an updated version of bettercap, in which the options completely changed. It's now got different command-line switches and some interactive mode. Needless to say, I have no idea how to use this bloody thing anymore and don't feel like learning it all over again for a single test. Maybe this is why users often dislike changes to the UI, and why some sysadmins refrain from updating their servers? When you have users of any kind, you should at all times honor their installations, give them time to change their individual configurations - tell them that they should! - in other words give them a grace time, and allow for backwards compatibility for as long as feasible.

3. devRant web app!!

As mentioned earlier I tried to scrape the web app's login flow with Burp Suite but every time that I try to log in with its proxy enabled, it doesn't open the login form but instead just makes a GET request to /feed/top/month?login=1 without ever allowing me to actually log in. This happens in both Chromium and Firefox, in Windows and Arch Linux. Clearly this is a change to the web app, and a very undesirable one. Especially considering that the login flow for the API isn't documented anywhere as far as I know.

So, can this update to the web app be rolled back, merged back to an older version of that login flow or can I at least know how I'm supposed to log in to this API in order to be able to start developing my own client?

#include <rant>

So, in my class I have this one dude who also code, "Awesome" I thought when I first saw that he codes, he codes in c# and claims to know JavaScript.

So I hung out with him a bit on recess/break time, and I eventually found out that he is a d*ckhead

First of all, he claims that he can code ANYTHING, I mean triple A games, the machine that can find pi in 10 seconds. And I know that this isn't true, because he "can't bother" with showing me it.. whatever I think.

I also mentioned that he is a d*ck, why am i saying that? Because if you make an error he would just go, "there is supposed to be *insert random bullshit here* instead of *a typo that I made*, retard. You are honestly fucking stupid" Listen, I love when people point errors out, it really helps. But when you say it like that, it honestly makes me sad. One day, I was messing around with classes in python and he went "hey idiot! That's wrong! There is supposed to be a *random word* instead of *working code*". The funny thing is, HE DOESNT KNOW WHAT PYTHON IS. So I comment out the working code and puts in his c# bs there instead. And he just says, "it isn't working because there's a private class instead of a public class. Ehmm, excuse me? This is python, ok.

Oh and he told me I was a retard because I can't develop triple a games using pure JavaScript.

Any tips on dealing with the guy?

My resolution for this year:

- learn PHP
- advance at JavaScript and figure out what's so cool about react.js
- be a pro with SQL and learn PostgreSQL
- build couple cool hardware projects with Raspberry Pi and Arduino based on C.

! exactly dev

I'd ditched Windows and spent a while exploring the Linux ecosystem for content creation. And I have to say, it was not a nice experience.

As much as I respect the Linux mantra of "free as in freedom" and "you need to roll up your sleeves and figure out stuff on your own", it just isn't good enough for non-dev work. Sorry guys, but I need software that gets out of my way and at least does what it's supposed to do. I can't stand a horrible UI or delays and random crashes, which is exactly what happens with most things under Linux.

To replace my Windows workflow I used the following:
1. Windows -> elementaryOS (because Debian/Ubuntu repositories seem to have the best software support, and elementaryOS is the least horrible looking thing that supports that) and then Arch, because, well, Arch.
2. Blender + Maya -> Blender + Maya on Linux.
3. Reaper + FL Studio -> Ardour + LMMS.
4. Photoshop -> GIMP + Krita + Inkscape.
5. ZBrush -> nothing :(

As you can see, my use cases are pretty much all over the spectrum.

Firstly, installing and configuring stuff. A pleasure on Windows, an absolute pain on Linux. Everything just worked on Windows, I had to wrestle with library versions and patches and unstable audio layers (Linux audio just sucks, except for JACK) on Linux.

Out of these, Blender and Maya were the best experience. But even then, both would suffer from random crashes that just didn't happen on Windows.
Ardour is actually really nice when it works. Its use of JACK for routing makes it really really flexible, but it just isn't stable enough to depend on. LMMS is utter crap. I'm sorry, but I just hate the UI. Can't stand it.
GIMP, Krita, and Inkscape can't beat Photoshop, even when you consider them together. Adobe software workflow is just so much better and more intuitive.
Blender 3D sculpting is not bad, but it's nowhere as good as ZBrush.

Also, if you're a C++ dev like me, nothing beats Visual Studio 2017. Nothing. That IDE just blows everything else out of the water. Even VSCode. And it's not slow at all, it handled a fairly large project (PBRTv3) just fine on my Windows development VM. Yes, a VM.

So...I ditched Linux and went back to Windows, but I keep Linux as a VM for when I actually want to mess with Blender or Ardour. Or some dev stuff which Windows sucks at (which is becoming less frequent because of WSL).

Out of all the above, the only one I'd consider ready for production use would be Blender. Developers of open source software, please learn from Blender. Kickass UI and user friendly operation is extremely important, you can't make a random window with GTK buttons and text boxes and arcane config files and expect people to use it for serious work.

Also, Windows beats Linux hands down as an everyday OS. It's always been rock solid, if you take care of it properly (and that goes for any OS). Updates hardly take any time because I run it on a SSD. As for all the advertising and marketing bullshit, you can block a large amount of stuff. And for what can't be blocked, well, I just have to live with it, because the alternative is compromising on my creative output, which is too much for me.

I still run Linux on my server, though. And on my embedded devices (Pi, BeagleBone, etc.). It absolutely rocks there.

I realize that Linux software is not going to improve unless we do something about it, so I'll be contributing fixes and code (the joys of being a C++ dev, yay). Still, I feel that the platform and software as a whole is just not mature enough.

Hobby at home... I feel I have MPD. Coding in php on Pi, C on Arduino, and C++ on Android to make my telescope an auto-focuser... Time to get usbip to work on Android

"If I were a rich man,
Yubby dibby dibby dibby dibby dibby dibby dum.
All day long I'd biddy biddy bum.
If I were a wealthy man.…"

If I were a rich man, I wouldn't have to build it from scratch and could simply buy a $15,000 telescope which had an integrated one...

- Learn git/github
- Create and finish a useful project on my Raspberry Pi
- Successfully organize a LoL tournament in my school, and develop something related to it
- Do not lose my mind when my programming teacher keeps saying bullshit
- Install a Linux distro along with my Windows as dualboot
- F u c k i n g clean that computer case a l r e a d y
- Finish the website I have been making for like half a year for my hobby
- Be active on devRant

So I set up push notifications from my Raspberry Pi to my Android phone, to know when exim sent a mail locally.
The easy part was the actual push notifications.
The more tedious part turned out to be looking for a way to send a notification for each mail.
After some research, Procmail seemed to be the only fitting tool to pass info to a command (in order to give the push notification some content so I know what's up)

In the middle of everything, I managed to fuck up exim system-wide, so mails didn't work, which was fucking great of course...

The magic receipt is this:
:0 c
| ${NOTIFY} -t "Pi mail: $SUBJECT"

Anyway, this is the result (using a test mail by mdadm + an actual degraded array I am still waiting on replacement drives for):

For fuck sake I get that people like python but not everyone is going to use it!

Just want a few articles or tutorials on interpreters and would you fucking look at that, it's all just in fucking python using external libraries...

Then I purchased a couple Linux and Raspberry pi magazines just to have a gander at some of the code examples and what do you think every single piece of code is? C? C++? Vala? Nope, fucking python!

I will eventually finish learning what I can about python but there are other languages that exist that isnt fucking python, give us some C, C# or even bloody JavaScript... Please

Ok rant about python over, back to my hole

Im seriously thinking about Watercooling my Raspberry Pi 3...
Why?
BRCAUSE THIS LIL SHIT RUNS SO FUCKING HOT THAT I CAN MAKE AN EGG ON IT! THATS WHY!

Its 80°C when under little load BUT GOES OVER FUCKING 90°C ON LOAD! AND THIS IS FUCKING DANGEROUS! FUCK!

so back to watercooling...
Its a Stupid idea, I know, but its literally THE ONLY FUCKING WAY TO COOL THIS BASTARD! And trust me I tried Novec (Yes the liquid that evaporates at 60°C...) and SHITS EXPENSIVE!

I learnt something from every single project I made, but this one... it was really different, new language, new library, new hardware.

Problem:
there's an infopoint in a place, that was really hard to use (ball mouse over a monitor)

Solution:
make the screen be touch.

Developing the solution:
- after a bit of research I find out there's a library/project called OpenCV
- there are example programs that detect hands written in C++ (which I know) and Python (which I don't know)
- the whole infopoint works on a raspberry PI, with raspbian (I'm not new to linux, but it's somehow different, plus tons of customization)

So I spend like 3 weeks trying to understand how to make it work, at first, the webcam was on the TV and you could move the mouse just by shaking your hand, but it didn't work too well, so we tried making the webcam look at the screen and then calculate the differences between "no-hands" and "user-hand", but should have been calibrated, wasn't too precise... dropped solution.

put the webcam 30cm above the screen, let it just analyse a few centimeters of sight from the screen and it worked flawlessly, BUT it could just recognise the horizontal axis => had to rework the infopoint UI to make it dumb-easy

It all finally worked, I learnt python, openCV, a bit of photography

Then hated it all and decided to never do that again

Anyone have one of the new MacBook Pros with Touchbar? I'm looking for some project ideas to work on.

I already am working on a project for the Pi-hole project (network wide ad-blocking) but I am looking for some other good ideas. I think Apple's view of the Touchbar fell short, but as developers I think it opens up a lot of possibilities to use it as a great information/monitoring tool.

I am also still learning Objective-C and Swift so I am a newbie.

Programmer: "Places : instead of ;"

Javascript: "What the fuck did you just fucking post about me, you absolute beginner? I'll have you know I worked for ten of the biggest silicon-valley industry companies, and I've been involved in over two hundred top secret projects including NodeJS. I am trained in refactoring the most fucked up code, and I'm the top C++er in the entire fucking internet-connected universe. You are nothing to me, but just another IP. I will fucking revoke your commits from your gitlab account with absolute dedication using only one Rasperry Pi client. Mark my fucking words. You think you can get away with posting that shit on one of my numerous very personal blogs? Your devices are fucking bricked, kid. My attack software can be anywhere, anytime, and it is tasked to remove your entire git contributions from planet earth. Not only am I extensively trained in remote cross-firewall device-hacking, but I have access to over 100 of the United States CIA and NSA git repositories. If only you could have known what doom-bringing C-one-liner you have raised from my fucking hands, maybe you would have held your fingers. But you could not. You did not. And now you're paying the price, noob. I will hail havoc upon your puny online-presence and you will drown in your own badly designed software. You're fucking offline, kiddo."

Hello there, Iam a third year student on Hasanuddin University, Informatics engineering. Iam little confused to choose the focus of my passion, because in the first year i interested to code HTML/CSS (as web programmer), than the second year i tried to code C# (to make game with unity) and than find a new interested on Java (Android Studio). Now i like to try IoT Programming (Raspberry pi). Any advice with my problem?

My older brother introduced me to linux and android custom roms when I was like 11. So I flashed my old sony Ericson phone with custom roms from xda and tried Ubuntu live CDs on my mother's old 40gb hdd laptop.
But my introduction to programming was when I saw some videos about the raspberry pi on YouTube.
I was like 14 and programmed basic scripts for my raspberry pi in nano over putty or notepad++.
At first I didn't even knew to intendent but in the process of my first project (Python sunrise alarm clock with tts) I learned many valuable things about Python and Linux/Debian.
The years after that I learned more with my now multiple RaspberryPIs, Arduinos and other hardware.
So in conclusion RaspberryPIs, the diy/open source community and especially my brother introduced me to programming.
I am now doing bigger projects with my brother and have (really basic) knowledge of java,Javascript,php,html,Arduino/C++ and Python.

TL;DR: New(-ish) dev looking for advice to improve workflow and new languages. Hopefully worth a read though :)

Newbie developer here, I took a web applications development class this year since I could take that at another campus rather than do general education courses at my home school, and I have learned and earned a CIW Certification for HTML5, CSS3, and JavaScript, though I know the certificates do squat if I can't apply myself to them, and I have learned PHP and MySQL.

I want to learn more, technically-applicable languages.

My setup is barebones (to a Linux diehard's eyes), with a gaming laptop that I do a lot of workstation stuff on, an RPi 3 B that I do some Linux-y stuff on, and a less-powerful Development Laptop (that I call a devtop) that I occasionally do work away from home on.

I'm sure most will cringe and weep at my workflow, as I use Windows 10 on both systems and the standard NOOBS software on the pi, and I use Brackets as my text editor, as well as the XAMPP AMP stack for testing.

My biggest questions are what could I do to improve my workflow, and what languages should I learn/apply myself to for real-world application (such as Node.js for live-updating server-side applications or C# for Windows applications)?

Thank you for taking the time to read this, any feedback is helpful! I'm just a high school student with a lot of enthusiasm for development!
