I want to finally try NixOS and build a desktop OS from the ground up with sway, iwd, waybar, foot terminal, cmus, etc.

I'm not a developer, but I'm a seasoned Linux user. Used Gentoo for years, Void Linux and now I'm on OpenSUSE TW.

I'm finding all sorts of guides and it seems confusing. In the past there wasn't any mention of home-manager and flakes, now it seems there are these things. Those are all things I need to care about? Is it all configured in one file?

I recently started classes again a little over a week ago. One of the classes I am taking is Computer science 2. One of the things it includes is openGL based graphics programming. They have us using glut, which is not bad in it self. However what they do is provide us a wrapper library for glut. In the form of a header named "graph1.h" and a precompiled library. Which goes by various names, such as "graphLib1.lib", "graphLib2010.lib", "graphLib2022.lib", "graphicLib2015.lib", etc. It's provided in the form of Windows flavored x86, Macos flavored x86_64 and arm. However, no forms for Linux. While I have been using Windows and VS Studio for classes so far, I strongly prefer my current Linux based tool chain. (text editor, build system, debugger). I have tried cross compiling with mingw-w64, but it fails when I try to link it. I would very much like to use it natively. To do this I would need either the library or the sources to compile it myself. That is what I would really like to find.

Here is more about the library it self. It is based off of BMPLoader, a small library for loading bitmaps as openGL textures. It also inherits its license from BMPLoader too, because it is a derivative of BMPLoader. (GPLv2; and has been distributed). When you unpack the library there are 3 object files, BMPLoader.o, loadPNG.o, and example2.o. (.o/.obj) I have found traces of it online, however they all link back to my University, University of Central Arkansas. I have also found evidence of it being used at GSU too, but it is from one of the professors that is now here at UCA. (They even provided a pdf on using it, I hashed them and they were the same). Here is a copy of the header graph1.h.

  I would appreciate it if anyone using this in something cool would tell me
  so I can see where it ends up.

  Takes a filename, returns an array of RGB pixel data
  Loads:
  24bit bitmaps
  256 colour bitmaps
  16 colour bitmaps
  2 colour bitmaps  (Thanks to Charles Rabier)

  This code is designed for use in openGL programs, so bitmaps not correctly padded will not
  load properly, I believe this only applies to: 
  256cols if width is not a multiple of 4
  16cols if width is not a multiple of 8
  2cols if width is not a multiple of 32

  Sample code:

	BMPClass bmp;
	BMPLoad(fname,bmp);
	glTexImage2D(GL_TEXTURE_2D,0,3,bmp.width,bmp.height,0,GL_RGB,GL_UNSIGNED_BYTE,bmp.bytes);

Right now I am of the opinion that it is a in-house "hackjob". That is how it feels with the GPLed BMPLoader glued together with other graphics functions. In an attempt to not have to use new literature or new style libraries with the new ".net 2008" style ide, as they were likely transitioning out of a codewarrior environment, and before that a borland environment.

So far, I have asked our computer science club about it. The main thing I was told was that the professor just wants us to use windows. That I can understand, but I still want to see how far I can go. I have also tried sending an email about it to the professor, but all I got sent was a link to the glut downloads. I did reply back asking about the graphlib sources too, but I haven't heard anything back yet. I don't want to push too hard, I still have a whole semester ahead of me. So now I am asking here on tildes. I understand if nothing can be found, but at least information and experiences can be collected.

Hi
With this LITE site ---> https://lite.duckduckgo.com/lite/
There isn't the Dark Theme that's available for original duckduckgo site.

I found a "My filters" rule on the web.

Add these two lines to My filters

lite.duckduckgo.com##html:style(color: rgb(141, 141, 141) !important; background: none repeat scroll 0 0 rgb(48, 48, 48) !important; font-family: 'Helvetica Neue','Segoe UI', Arial, sans-serif;)

lite.duckduckgo.com##a:style(color: rgb(201, 201, 201) !important;)

When the rule is used the search homepage looks reasonable.
And the search results...
The black background is not very black, not as black as Tildes black theme.
I can live with that.

But the red text under each result is very muddy.
Can that be improved?
Make it brighter Crimson or even Orange would look better.

How do I add a `UNIQUE` constraint?

I suspect many don’t write anything down and do this largely by intuition/experience but I want to tease out some ideas.

when it comes to describing and designing a system from a blank piece of paper, what are the parameters you think of?

I’m thinking napkin sketch level of software design.

So things like:
Number of users, are they concurrent users, what load dimensions there are (disk IO, network IO etc.), target platform (everything is a web app these days), how do you design/visualise the data model?

Any decisions or constraints that impact what and how you build a proof of concept / MVP? How do you document this? How do you test it against the finished software?

As an amateur photographer, I'm looking for recommendations to improve my process for reviewing and selecting the best photos from my albums.

Currently, it goes something like this:

• (after I copy the photos to my PC) I open the folder containing the album
• I open the first photo and start looking at the pictures using the default photo viewing app
• I note mentally, on paper, or in a digital notepad the names of the files that I like the most
• manually select the files that I noted down

My ideal workflow would be something like:

• open the folder, open first photo, look through them all
• each time I see a picture that I like, hit space or some other simple shortcut, which adds the picture to the current selection
• after I am done viewing, I have all the files that I want already selected to do with as I please

I have tried multiple apps over the years but I haven't come across anything that had something similar, or I was too stupid to figure out how to do it. The workflow I described is using windows/linux, on macOS it's even more cumbersome (since one needs to select all photos in a folder before previewing them).

Do you have any recommendations for an app that has functionality like this, or if not, on how I can make my workflow better?

Thanks

I am not sure if there is a proper name for these—frequently, a news article will be broken up by large-type excerpts of one or two sentences from the very article I'm already reading. I find this obnoxious. Has anybody made a tool to hide them?

Hey! I’ve been trying lately to get rid of big platforms from my life. One part of it is that I usually buy ebooks/audiobooks from apple, Amazon or google, however I’m then also forced to use their reading app, which is a vendor lock-in I’m not comfortable with.

I know there are plenty of ebook readers out there, but I’m trying to find

1. A store where I can buy ebooks that can be opened in a ebook reader of my choice.
2. A way to then sync my progress between phone and laptop. I have nextcloud setup, so if I can make use of that then it’s perfect.

Anyone here got any tips?

So... a friend did this for me a long time ago, but I've replaced my computer since then, and I don't know how to do it for myself.

I know how to find the MAME executable. I don't know whether I need to download the .exe file or the .zip file, but I assume the .exe file is the better option.

I know how to run an executable file, and I'm assuming it installs itself.

I know how to find a copy of the antique video game I want.

However...

The .zip file I download for the game contains a lot of files with names like "a26-13.109" - and I don't know what I'm supposed to do with those, to get them inside the MAME and make the game playable.

I'm running Windows 10 on a 64-bit operating system, if that's relevant.

Is anyone feeling charitable and willing to help someone who's not computer literate to do this?

I used to work in IT but left the field in 2018, so I'm not as up to date as I used to be on things. I'm looking for a new laptop to use for work (primarily word processing and web browsing), ideally something portable with a good sized screen (larger than 13"). I've had a Dell G5 for the last five years because I thought I'd do more gaming on it when I bought it, but it's largely just been a heavy brick in my backpack on travel.

Back in the mid 2010s, I recommended Lenovos to everyone who would listen, but I fell out of love with them toward the end of my IT career when the build quality seemed to be rapidly declining. I haven't really touched them recently, but my dad loves his Lenovo Ideapad Pro.

Honestly, something similar to a Dell Latitude might be what I'm looking for, but I'm open to any recommendations. I need a responsive keyboard and clickable trackpad. Bonus points if there's somehow a laptop out there that has a nub!

ETA: Not looking for a macbook -- will be running Windows!
