The article didn’t go into this, but I suspect that a large part of the dark mode trend is due to evening/night computer use. If you don’t light your room, the screen is the only light source which is unpleasant.

I would argue that you don’t need to learn string theory as it currently does not predict anything we can realistically observe (as you need energies that occurred only at the big bang). If string theory is correct we could observe a “super

Maybe the following helps: if you have a an analog signal where there are no frequencies above 22.05 khz, it is in principle possible to sample it at 44.1 khz and then perfectly reconstruct the original signal from those samples. You could

This is a story about a unique 1947 Chinese typewriter prototype that never got built. It could type thousands of characters by combining keystrokes. The prototype was presumed lost, found this year and it is now at Stanford. This is not ne

i have wasted several weeks worth of evenings on vectorizing heaps (4ary heaps: with SIMD, you’re not limited to binary heaps). It did not provide any speedup. I’d expect that halving heap depth would help but no. Still don’t know why.

Nice to learn about. It’s good to know the field has progressed, however the context focused on JPEG, where my point does apply.

Arithmetic coding decodes 1 bit at a time, usually in such a way that you can’t do two bits or more with SIMD instructions. So it will be slow and energy inefficient.

Yeah, it’s a funny coincidence that all those constraints to make it look random produces exactly one solution. I guess the OP knows this is not ‘random’ in the mathematical sense.

Yes, or when a character moves across the screen. They are quite fine grained. However, when the decoder reads the motion vectors from the bitstream, it is typically not supposed to attach meaning to them: they could point to a patch that i

I love this. The widely used standards for video compression are focused on compression efficiency, which is important if you’re netflix or youtube, but sometimes latency and low complexity is more important. Even if only to play around an

Well, it is not pretty to see how the sausage gets made, but extracting formatted text from docx is absolutely doable, no PhD involved. Source: I have done it as a little sidequest because it was useful to audit a set of word documents.

Ok this is correct for traditional JPEG. Other flavors like Jpeg2000 use a similar (but lower overhead) version of this byte-stuffing to avoid JPEG markers from appearing in the compressed stream. Related: https://en.wikipedia.or

There is a particular pattern (block/tag marker) that is illegal the compressed JPEG stream. If I recall correctly you should insert a 0x00 after a 0xFF byte in the output to avoid it. If there is interest I can followup later (not tod

Because there’ll likely be a lot of string concatenation in a language whose job is to output HTML. Adding a single char to a 1k string will require allocating a modified copy, in mutable strings it’s just appending in a preallocated buffer

It’s true that many languages have immutable strings, but for a web-focused scripting language it makes sense to default to mutable strings. I think the comment is about that you now need to choose mutable vs immutable, and that is framed
