>>61515>try to look at the html of twitter. it's not even human readable. Reactjs is fucking gay. it's also these javascript websites that have weirdly autogenerated obfuscated elements and namesIt's really bad. If you scroll down twitter the next block of posts is returned as a (deeply nested and garbled) json response based on scrollbar position, then that response is appended to the dom with javascript. It's designed to be slow and hard to scrape. Thankfully, like you say, people have made better public apis.
I've been porting my image/booru viewer from lisp to c. The initial port used sdl, but it's 2slow4me so I'm using plain opengl now. The first problem I encountered was managing the limited number of texture units on the gpu, which sdl does for you, because there are more image thumbnails than texture units. In the screenshot the 512:512 texture is uninitialized memory, then the unordered thumbnails are stamped in the texture using shelf next fit. Tomoko on the right is drawn using the normalized uv coordinates returned from the function.
Also, I like the opengl 1 api better than the newer versions. You should be able to open a port and stream instructions to the gpu, or do it the ogl 1 way. The newer stuff overcomplicates things. Different stages of the modern pipeline could be exposed as registers instead of the inout parameters in shaders for example, it would be simpler and faster.

>>61556Added text stuff and asynchronous autocomplete with caching.
The main problem I had was my string pool used realloc to resize the pool, but I forgot you may lose anything that was pointing into the previous allocation, so my strings would get overwritten with server responses, and the async stuff would write into freed memory and crash the program. The fix was to expand the pool by putting new allocations in a list, so they don't change over the lifetime of the program.

>>61602Now we can browse pages and download stuff.
There's not much new functionality. The program just extracts the necessary fields from each post (if they exist), compares them to a cache of posts, and if we don't have it download/decode the thumbnail, adding it to the texture atlas. The draw list just points into the cache and is assembled on the fly. Most of the speed improvement in this area is from using persistent connections and decoding jpegs in parallel, but we're ultimately limited by the speed of the server (200-300ms) unless the cache is hit.
The program is basically finished, but there are still lots of refinements to make:
>be able to navigate by rows (the program just blindly draws until it reaches the edge of the window, so it has no idea what a row is)>center thumbnails vertically>rendering is incredibly slow, we spend 3ms making 352 opengl calls just to draw a page, it can be sped up by throwing all vertices/uvs in an array>maybe prefetch the next page to make browsing faster>add a download queue, instead of blocking the program like a retard every time `d' is pressedAnyway, I'm really happy now it's usable, this is much nicer to use than my first attempt.

how do i add this

No.61897
>>61895>it says i need to either build it myself, or use nuget.nuget is presumably a package manager for wangbows. all it will do is pull down the source and dependencies for imagemagick and build it. you can see what's happening at a high level by reading the build scripts in your link (for instance Magick.NET/src/Magick.Native/build/Build.cmd, install.ps1)
>it's used by visual studio. do i really need to use that collossal bloatware garbage?you don't need to use visual studio's compiler and linker (cl.exe), you can use whichever c compiler you want to build imagemagick. on wintoddler 10 this will likely be mingw or clang
the instructions for what you want to do are literally in your link, it's just a remarkably badly written wrapper library (i lost my patience when i saw xml in comments), so you'll have to invest some time into examining how dlemstra builds imagemagick and creates a c# binding for it to integrate it into unity. the main difference will be instead of using whatever datatype dlemstra defines for wrapping imagemagick's representation of images you will use unibabby textures instead
No.61899
>>61897man i hate the process of building from source. i know some people find that fun. i find it tedious and it pisses me off when people don't just include compiled builds with releases
i will probably just bundle imagemagick with my unity prject and use it by creating and running batch files. this breaks compatibility for linux and mac though
No.61901
>>61899in the case of a batch/shell script, you'd just check to see if the user has the program installed, but there are more efficient ways without invoking a shell: you could either run the program as a sub-process, or dynamically link against the imagemagick library (.dll on wangbows, .so on loonux) and use c#'s foreign function interface
No.61902
>>61901yeah i know how to run batch files on window as a subprocess and have the window and output hidden. i'm not going to bother trying to oop-ify the process of feeding parameters into an external program, the imagemagick commands are simple enough. thanks

Bit of harmless fun:
1. Outside code blocks:

$1 = #f
2. Inside code blocks:
scheme@(guile-user)> (string-any #\; "->")
$1 = #f
So as you can see, while untyped wizchan calculus might be consistent within its domain, it is inconsistent as a deductive system. You don't even need fixed-point combinators to prove this, all you need is a code block. ;)

not programming, but there is no general tech/software thread. does anyone know what would cause drop down menus in firefox to stop working?
for example, when making a post on wizchan, the email selection has a dropdown. no menu displays for me though, i have to click somewhere on it, then press left/right arrow to select something. it's been like this for maybe 5 years so i'm used to it, but every now and then i am reminded of it. like signing up for websites, picking my country/state is always annoying. i have to type 'u' to jump to countries starting with u and then click right a few times to reach usa

>>62340the profile css stuff is fine. and that particular config is ok. i just have too many configs set it has to be one of them, if i check 'show only modified' it shows almost 1000. a lot of it is to disable telemetry, sensors, popups, notifications, pocket, etc but a number of problems including this dropdown thign have appeared, like being unable to update addons or the browser itself. the next logical troubleshooting step is probably just to reset the about:config to default to see if that fixes it
No.62342
>>62341it's normal to have so many configs changed, but it may just be after 5 years there's a config conflict as firefox has changed. you could save yourself some time by either trying help > troubleshoot mode to reset all settings temporarily, or go to about:profiles to try running firefox with a fresh profile (you can also do this by running firefox -p in a shell) if you're curious, about:about lists everything
or it could be something completely unrelated, like the doubleclick interval on your mouse being so short it opens/closes select menus instantly, but you would have probably noticed that long before

Aso net core Mvc
Spent like 5 hours yesterday screaming at the screen because my viewmodel was empty when i tried to update it on it respective post controller. After a lot of stress near the deadline i figured it out. The viewmodel wasnt getting anything because i put a name attribute for my select so it was appearing on the Request.Form array but not on the view model.
Good damn Microsoft fuck net core its a terrible language. Why in the name of good you got select tag helper, dropdown list and other stuff that deserves the same porpuse but it just have different names with minors differences. its confusing and annoying as fuck when you try to google a error but half the solutions doesnt work for you because they are in razor pages or in .net 4.7 or whatever the hell those idiots just build out of nowhere just to disccount it after 2 years.
