Damn, github should show some big visible warning about this.

These trolls really exist on Russian social networks, trying to refute any news from the opposition media. And some people (Russian enthusiasts) count and list these bots. But your article does not prove it to me, because some Russians are

It is very sad that the authors of the article either believed in all these accusations against the Russians or are afraid to say that this is nonsense so that they are not accused of supporting the Russians. I want to note that the Russian

Any number is remarkable if you're smart enough to find why it's remarkable.

If it's an outdated pesticides, as suggested in another comment, then it's very related. Because it's a leakage from an old Soviet storage tanks.

Using compiler hints, data can be placed directly in the code section. Works on x86/x86_64 Linux: char main[] __attribute__ ((section(".text"))) = "\xe8\x0d\0\0\0Hello world!\n" #ifdef __x86_64__ "\x31\xc0\x8d\

He is also one of the developers of Bad North, where islands are procedurally generated, much similar with this demo.

About that "write-ppm" example. Using PPM type 3 will increase the size of pixel data by 2-4 times. Use type 6.

I don't have the general problems with reading, but I do have the problem you mentioned. And I'm also kind of a speed reader, I think the problem is here.

It reminds the index of the first element in an array in different programming languages. Some use one-based indexing, others use zero. Which causes problems (bugs) when porting the program to a language with different indexing.

Modern computers have some sources of entropy that can be used to create a random numbers. For example, the timings of the memory access, race condition of threads. User interaction (mouse movement, delays between keystrokes) can also be us

It goes fine with mozjpeg. I tested a little, didn't find any problems.

I've seen these projects on github. I don't remember the names, only that waifu2x upscaler has an NN filter for JPEG artifacts.

Use "-w 0.0" switch to jpeg2png, gives slightly sharper results. Also try with: https://github.com/ilyakurdyukov/jpeg-quantsmooth with "-q6" (default setting without luma-aware chroma upsampling) My

"All JPEG decoders have chroma upsampling." Well, I meant better upsampling than bilinear interpolation, which blurs chroma. "Oh, you can also jointly optimize the YUV-RGB conversion because if the pixel ends up out of range

Both of these projects have chroma upsampling.

By the way, you can decode JPEG with less artifacts using these projects: https://github.com/ilyakurdyukov/jpeg-quantsmooth (good for most mid-quality and high-quality images) https://github.com/victorv

Actually - JPEG is not lossless even at 100% quality, there is a little noise at +/-1 of pixel value, some rare pixels at 2. Grayscale is not needed, you may skip RGB->YUV conversion and encode in RGB colors, libjpeg can do that.

And I also have questions about decompression speed and memory requirements.

JPEG quality can probably be better (but slower) when using sophisticated decoder libraries. This way, a JPEG image with a WebP size may look with the same quality. But I didn't test. https://news.ycombinator.com/item?i
