I am interested in looking into the feasibility of making a program to find good deals on groceries closest to a particular area, even with a notification system. I hate that food insecurity is a problem to begin with, it makes my blood boil. Fuck this inhumane system.
A sky-blue wallpaper depicting a group of seven squares colored in the Windows colors, with a Windows 95 era logo in the center. The background depicts a set of clouds.
Ditto, sans the clouds.
Alternate version with squares lacking the fill.
Ditto, without clouds.
As requested by @zedfurry.me, here's another Windows oriented wallpaper (plus variants), this time combining the design elements of Windows 95, 98, Me and 2000.
This one was a lot easier to make, due to the understated nature of 90s era Windows design.

Cybersyn seemed like a very interesting idea. What is your sort of idea to reimplement it? I figured that would be tricky given that it is distributed and very old with probably little information left on it. Let me know how it goes because I am quite interested.
Been finally studying for my math class after a hard week of technical difficulties etc, statistics isn't so bad. I kinda got screwed over by my earlier math classes but it's a lot closer to what I remember doing in high school.
Progesterone got 3 cartoonish dark-blue Z's floating over my head
That's probably what I get for solely focusing that for like 3 months lol
I've gotten a lot better at handling shitty old code with my most recent project but I'm kind of running out of ideas on what to do with it
The only way to have code that isn't shitty is to have rediculous code quality guidelines and absurd amounts of testing but then it takes forever and is more bureaucracy than anything
But I mean NASA's code is probably pretty decent... probably... I would hope...
"if it's fixed, break it"
First day of the new semester wasted because for some reason the IT department changes every single last thing every semester. We change what LMS we use, what version, what theme, where we attend lectures, what specific software is needed, what authentication we need etc... and then it's broken lol
college starting back up aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaahhhhhhhhhhhh
You're not just gooning — you are rewriting the narrative on what most consider the edge of human potential. That's rare. Would you like to turn this into a motivational tweet, encourage your deepest fears until reality is torture, or simply appreciate this moment while it lasts? Just say the word.
the whole heheheee begin a block with the expected keyword and end it with that word but reversed is the dumbest part of Bash
WHAT IS AN ESAC
do you guys think this covers me perhaps

It's actually better than calculating the remaining time in the tic and then sleeping for that. That could be probably ok if you pre-calibrated a timer to figure out how long say 1ms would actually take, but still poor. That game loop should be rewritten wholesale at some point.
A lot of times CalcTics is called twice and also GetTicCount is super expensive and called a lot
Fixing all that really made it smooth enough to make this latency trade off worth it, I was trying for a better solution but this is what most Doom and Wolf3D ports do after reading some code.
I was playing around with Barrett on my T420 and my CPU got to 95c
I was really adverse to it but I put a 1ms sleep in there.
Worst case that tends to result in 10-16ms sleep because of OS scheduling BS but it's okish because a ROTT tic takes 28.5 ms so is still within margin.
Everything is either green or blue. I figured this theme would at least have some yellow, having functions and variables both green is diabolical even for the time
I found a Turbo C theme for vscodium lmao
I hate having eyeballs
Here's some of my shitty code from my rewrite of WinROTT's crosshair code to show it
For reference, the T420 has an i7-2640m, Sandy Bridge so supports ISA extensions up to 2012 (AVX 1 ceiling basically), 16gb of I believe DDR3-1600 SODIMMs... Runs pretty well considering. I would like to maximize performance headroom so large maps can hit 35 FPS at native screen res on most devices.
But that would be severely bottle-necking the renderer on other platforms, especially older CPU architectures, slower RAM etc.
I want Barrett to be very portable, compatible, and fast on as many devices as possible. 4k already runs pretty decently on my Thinkpad T420 but I feel I can do better.
I've already basically hit the ceiling for optimizations without rearranging memory and using SIMD but GooberMan said only rewriting the floor renderer in SIMD was worth it... probably because of an issue like this
The only thing I can really think of is rendering sprites, walls etc into a transposed secondary buffer and then rotating it back and merging with the other layer. But that also raises concerns about memory bandwidth, latency, how fast can you copy and merge 2 buffers and display them...
This doesn't even make sense because I would just be offloading the cache-line invalidation onto the floor renderer which is already way less efficient than the column renderer. Floors and ceilings using rows is the only reason they run acceptably at all despite being more expensive.
I am going to look into backbuffer transposition as another ROTT optimization, it looks like that would help with a lot of rendering
I suppose I'm just curious how I'd fit things that already draw in rows like the floor. Maybe render to separate surfaces and combine? I have no clue
Those bit manipulations take like 35% of the floor renderer's time. The floor/ceiling renderer also takes up 5-12% of the total execution time in my tests. Sky rendering used to be 15% but is down to 3-5% because of the LUT. That goes to waste on levels without skies though.
The floor renderer is still pretty expensive because every iteration it does 2 shifts, 2 ands, and an OR. It's only reasonably fast because the floor and ceiling generally don't take up much of the screen
I used a look-up table to optimize the sky renderer but idk if that's as simple with this
Been working on optimizing Rise of the Triad's software renderer and am starting to push 30 or so FPS at 4k. It dips quite a bit but I'm having to reach pretty deep for optimizations, even using link-time optimization etc
I think it's gonna need SIMD to be any faster
