kandi X-RAY | kram Summary
kram is a wrapper to several popular encoders. Most encoders have sources, and have been optimized to use very little memory and generate high quality encodings at all settings. All kram encoders are currently CPU-based. Some of these encoders use SSE, and a SSE to Neon layer translates those. kram was built to be small and used as a library or app. It's also designed for mobile and desktop use. The final size with all encoders is under 1MB, and disabling each encoder chops off around 200KB down to a final 200KB app size via dead-code stripping. The code should compile with C++11 or higher. kram focuses on sending data efficiently and precisely to the encoders. kram handles srgb and premul at key points in mip generation. Source files use mmap to reduce memory, but fallback to file ops if that fails. Temp files are generated for output, and then renamed in case the app fails or is terminated. Mips are done in-place, and mip data is written out to a file to reduce memory usage. kram leaves out BC2 and etcrgb8a1 and PVRTC. Also BC6 still needs an encoder, and ASTC HDR encoding needs a bit more work to pull from half4/float4 source pixels. Many of the encoder sources can multithread a single image, but that is unused. kram is designed to batch process one texture per core/thread via a python script or a C++11 task system inside kram. This can use more ram depending on the core count. Texture-per-process and scripted modes currently both take the same amount of CPU time, but scripted mode is best if kram ever adds GPU-accelerated encoding. Similar to a makefile system, the script sample kramtexture.py uses modstamps to skip textures that have already been processed. If the source png/ktx/ktx2 is older than the output, then the file is skipped. Command line options are not yet compared, so if those change then use --force on the python script to rebuild all textures. Also a crc/hash could be used instead when modstamp isn't sufficient or the same data could come from different folders.

kram Examples and Code Snippets
kram[encode | decode | info | script | ...]
Usage: kram encode
-f/ormat (bc1 | astc4x4 | etc2rgba | rgba16f)
[-srgb] [-signed] [-normal]
-i/nput
-o/utput
[-type 2d|3d|..]
[-e/ncoder (squish | ate | etcenc | bcenc | astcenc | explicit |
*ASTC*
Android and iOS, Apple M1
Requires swizzles to reduce endpoint storage (rrr1, rrrg, rgb1)
Full 8-bit channel endpoints
No HDR L+A dualplane, only RGB1
No signed format
ASTC4x4 is same size as R8Unorm explicit format.
Can change block size acr
GPU - none of the encoders use the GPU, so cpu threading and multi-process is used
Rescale Filtering - 1x1 point filter
Mip filtering - 2x2 box filter that's reasonable for pow2, and a non-linear filters for non-pow2 so there is no pixel shift

QUESTION
I have a queryset that returns a list of menus that and I want to assign each Menu a rank based on the number of votes accumulated is there a way I can achieve this using django Query Expressions? I'm also open to any other suggestions.
The queryset is as follows:
qs = Menu.objects.filter(Q(created_at__date__iexact=todays_date)).order_by('-votes')
And the Menu class model is shown below:
...ANSWER
Answered 2021-Jun-03 at 08:07You can either use the index of the object in the array as its index or you can use Window
functions [Django docs] and use the Rank
or DenseRank
(Reference [Django docs]) function to compute the ranks as per your need:
QUESTION
I am building my own programming language and I came across a problem. All programming languages, I discovered, have # include, import, # import
function .I am trying to implement this same function in my own programming language, but I am not sure how to.
Could you explain how import functions operate, how compilers interpret them, and how I can do the same thing in my own programming language?

Answered 2021-May-13 at 12:26In the C language that is done by the preprocessor. Take a look at this wikipedia page.

As described in the title, I am new to Python(programming in general) and I tried making a bot, however the bot does not respond to commands. I followed/looked through multiple youtube tutorials & articles, but I cannot find a way to fix my problem.
