There seems to be a solid community of Linux people growing here, so thought I might try asking...

I'm building a head unit for my car, using a Raspberry Pi to a 7" (and eventually 10-14") touch screen.

I'd like to have a fast-booting Linux distro with tiling windows that lets me set up a config file to launch a bunch of programs that are tiled perfectly edge to edge, with minimal border (a 1px line us OK), minimal header (just the name of the program? or none at all maybe), and have them all locked in place so I can't accidentally drag one or resize one when touching audio controls, for example.

The idea is to have a few windows, such as an audio player, a GPS map, 2 dash cam feeds, and an OBDII style sensor readouts, all on screen at the same time, each sized differently.

I've got each individual program working fine on Raspbian right now, but no idea how to go about the tiling-on-boot, locking them in place, etc.

Can I do it with Raspbian with some specific window manager? or do I need a different distro?

Thanks in advance.

So I tried to install sway on my desktop today. This required a lot of fiddling, as I had to pull in bleeding-edge dependencies for the Wayland libraries, and had to build the compositor framework wlroots. Finally however, I had everything compiled and ready to go and....

Proprietary Nvidia drivers are not supported. Use Nouveau.

I had completely forgotten that sway requires open-source Nvidia drivers. So - has anyone had experience using Nouveau? How usable is it from day-to-day? How noticeable is the performance hit when switching from proprietary drivers?

Companies can technically and legally track just about everything you do at work digitally, from your entire browser history to even particular usage patterns on company web apps. Should there be an expectation that companies disclose what they do/do not track to employees? Or should employees have to just live with the fact that companies can and will spy on them as a cost of doing business?

I've just used Tildes on my phone for the first time and FUCK! MY EYES! I know I can't change the color of Safari, so I looked in the app store but couldn't find anything. Can you reccomend me a good browser with a dark theme?

Hi everyone, I'm a frontend developer and do a bit of backend work as well. I'd really like to contribute some of my downtime to helping build this site. I've checked out the issue tracker on gitlab and some of the docs, tech goals and announcement, but I'd like to start getting my hands dirty and contribute some code.

• Is there a roadmap for development?
• A feature list to implement?
• Bugs to fix?

How can I help out? What's the best way to get started?

Also for all non-devs, what is the best way that they can start helping out?

Hey guys -- I wrote a blog that I'd love some feedback on. I'm an identity product manager and have been trying to train my users to use passphrases. Do these read friendly enough? I want it to be readable by all users, but my target audience is other people in product and software.

[Context: I do computational research in the natural sciences.]

I have been tasked with verifying the correctness of a ~3000 LOC software project written in a mix of Fortrans 77 and 90. I have made some small amount of headway with getting the program up and running, but it seems like every time I make one step forward I take ten steps back.
Some issues with the program:

• It only compiles with one, specific, closed-source compiler
• Useless variable names
• Minimal comments (the ones that do exist are near-gibberish, explain the obvious, or comment out debugging print statements)
• Weird decisions are made with no justification, e.g. the code author decided that, if we are considering the calculations on the first molecule, we are only to consider its first atom
• Magic numbers everywhere, very few of which are known physical constants or their conversions
• etc, etc, etc.

I am reaching peak frustration after having worked with this code for only a few weeks. At this point, the idea of sitting down and rewriting the program from scratch is very, very tempting.
Do I need to just step back, relax, and keep hitting my head against the wall, or is this a situation where a rewrite may be necessary?

The point of this thread is to post your code for solving the task. Other will comment with feedback and new ideas. Post what language (and version, if relevant) your code is written in.
Have fun!

I've been thinking about messing around with Z80 ASM for a while with the end goal of doing interesting things with one of my old TI calculators. Finally got around to doing some googling, found this guide to the basics, and thought I'd share it for anyone else who might like to read it.

Disclaimer: I'm a novice and this is a half baked idea

Recap

The Caesar cipher is fairly straight forward as it just shifts letters along by a set amount. This means that it's quite easy to brute force. There's only 25 offsets, after all. Try to decode this to see what i mean:

bonus points for a program that takes the above text and outputs the shift I used without any human input

My dumb idea (didn't work, my bad. They're in normal Caeser cipher now)

I like the simplicity of the shifting characters but having it always be in one direction, and always being the same offset makes it easy to notice the pattern and decode.

If we have the shift value determined by the length of the current word, and the direction of it dependent on if it's a vowel or a consonant.
a pirate is nothing without his ship becomes
b jolgnk kq gvmapgz ppmavbm elp odml so we still have a visibly Caesar-y cipher, but we'll know it's not a true Caesar cipher.
The offset changes for every word and then is applied based on each letter in the word. If it's a vowel, then the encoded value is shifted upwards but if not, it slides down.

For the purposes of the below tomfoolery; prime numbers are consonants and the rest are vowels.

These are encoded using a Caeser shift. The line under the title is a fixed phrase (a pirate is nothing without his ship) for aid in the bonus points

I can post my code if it turns out to be unsolvable (like a bug https://trinket.io/python/dabf2b61f9), but if not; I can also keep going from letters A to Y (sans U) over the weeks with my humble bundle reserves (plaintext or not). I've had these keys for far too long and I'm never going to actually use them, but I also noticed a surge of keys being donated here so figured I might as well change it up.

Have fun

One big thing that has made maintenance of my older code easier has been considering the concept of cyclomatic complexity. In particular, limiting conditional checks to exceptional cases as much as is reasonable has made it easier to focus on the "happy" path of code execution and easily track down the errors, and the limited nesting depth has made things easier to read as well. Overall, my code remains relatively flat and I'm not branching through layers of logic trying to track down a simple bug.

What are some simple things you do to keep your code from being a massive headache long-term?

I've only been seriously programming for about a year now (and mostly in R), but I've been digging into Python for the past few months. Mostly I use pandas/numpy/scipy/scikit-learn, etc. for data analysis and some ML stuff, but in an effort to expand my skills I've also been playing around trying to build a few projects.

It's not much, but I built this: News Desk

Feedback is welcome. One bug that I'm aware of is that when you refresh the program, the url_list isn't cleared and the URLs from the refreshed articles are just appended to the list. So even though only 20 articles will show, you can select, for example, article 35.
