New compression algorithms are always interesting because they reveal a new way of describing a photograph in a succinct way. The overlap between image compression and image searching is surprisingly high because the same techniques are us

PNG will always do a bad at compression. PNG is deflate encoded, but without the ability to rearrange pixel data to work with deflate's strengths. It will pick RGBA, which mixes the "entropy" data for each color channel tog

Java's SSL is very painful to deal with. It has no support for ALPN or NPN, making it really difficult to use for HTTP/2. Also, the GCM cipher suites are implemented in Java, not with Intrinsics, so they are painfully slow. As

> This means I need to take the default CipherSuites and simply remove any that use a cipher smaller than 256bit. Arguably using a higher bit cipher suite should be considered worse, since it reduces accessibility. 128 bit crypto (speci

Can't help but wonder if attackers already knew this. There seems to be quite a few bugs found by taviso in antivirus code in the past few months, which has got to either attract attackers to look more closely at it or possibly break

It looks like this binary searches across the Go quality levels to find acceptable quality. This isn't a bad idea, but it won't be fruitful. The Go standard library JPEG encoder is pretty basic, and reuses the quant tables from

Those are all really good points actually. In response to them individually: - The problem with generating id's is that it isn't known ahead of time how many there will be. This forces a solution that is suboptimal in all circum

Does the same effect happen with 100% relative humidity?

If you don't care about side effects: C: int foo = bar ? 2 : 4; Go: foo := map[bool]int{true:2, false:4}[bar] Python had a similar trick before 2.5 added ternary conditionals.

Awk is great at what it does, but I find myself unable to keep it cached in my brain long enough to reuse it. Using awk usually means a google search of how to use it, which defeats quickly working at a term.

Huffman coding is probably one of the more interesting ones, not only because it is so ridiculously useful, but because of the wide taxonomy of implementations. It is quite malleable, able to be morphed and optimized to the particular appl

Getting your picture taken kind of puts you on the defensive, but that probably isn't going away. You have to be able to go outside, go to the bank, go to work, and go to the grocery store. Each of those places are going to have cam

Alternatively they could make their own API, independent from OpenCL. I have written a small amount in each languages (a rainbow table generator), and found the CUDA version much more pleasant to use. CUDA made it really easy to get a goo

If you have ever watched the TV show Black Mirror, it does an exploration of what it would be like to have instant access to know everything about a person by looking at them. The technology becomes a commodity and results in the destructi

A couple reasons. Look at these as something HTTP/2 does well, but maybe not the best: Head of line blocking is mostly solved. You can interleave sending big messages with small ones. You can send control messages (like "Hey, I
