I honestly haven't heard the term constant time used in a context other than asymptotic in computer science, even in relation to side-channels. I think this is the way the majority of people use the term. I worry that trying to use

Asymptotically constant is what we normally talk about in relation to constant time. An algorithm that always runs in n steps with respect to input would be considered constant given the definition you're using, which would at very

This isn't correct. Consider an algorithm that special cases powers of two for dividing a number. Both cases take a constant number of steps, although dividing by a power of two is fewer. The lower and upper bound differ, but they ar

The main advantage is that it's a smaller dependency. If you don't need the functionality, there's a bigger benefit to being portable. For example, running scripts on a router with embedded linux.

On x86, it could also compile down to just a jmp . A bsr would still be faster, but it would probably be worth checking that __builtin_clz actually compiles down to bsr . For portability reasons, it might be better just using bit tric

I use pup a lot too, which just prints the dir.

It's useful to be able to write functions for your shell. For example, I have a function up , which moves up n dirs.

I've started trying to stick to dash syntax for shell scripts.

The macro/command syntax for mutt. For example, tagging all the email from someone and saving it to a folder (Tsomeone, ;s=folder). Filter rules as well (e.g. sieve).

I'd have a hard time switching to an email client other than mutt. I'm not sure what I would do without an actual grammar to deal with email.

Considering a lot of content seems to be increasingly generated and handled via Javascript, what are some of the downsides to statically generating a website or webapp?

GPLv3 has to do with locking hardware ( https://en.wikipedia.org/wiki/Tivoization ), which Amazon is still vehemently opposed to for obvious reasons.

I tag my music through MusicBrainz ( https://musicbrainz.org/ ) and I generally don't have to worry about metadata anymore. I generally try to correct anything I find that's wrong. abcde + picard + ncmpcpp.

Interesting results. Thanks, I'll have to take a deeper look through the paper. Cuckoo hashing seems to be the standard, but I still haven't seen concrete numbers comparing different variations or other schemes like hopscotch par

Does anyone know if there are any similar studies for hash tables (e.g. algorithm, bucket layouts, probe sequences)?

The rebuttal has to do with the definition of economic growth (assuming it isn't connected to energy consumption and gdp), which the economist argues has to do with quality of life. The rebuttal is that quality of life can only object

The other article isn't entirely arguing that energy is a fundamental limit, although the example it gives is pretty hilarious. It's ultimately arguing that there are fundamentally limited things for capital to invest in and grow

The math is essentially correct, but it oversimplifies some things, and it skips a number of factors. Larry Summers recently shared his opinion on the topic https://www.washingtonpost.com/opinions/the-global-economy-i..

I'm just not entirely convinced of the premise that energy consumption on that scale would be necessary for an advanced civilization. Particle accelerators would be a reasonable possibility though.

It isn't a question of testing changes. The more people working on the codebase, the more people it impacts. Adding manual steps is tempting the fates.

Python is definitely a better syntax to write meta-programs than the pre-processor, but you still have the issue of the additional step/tool. Anything that depends on the generated code depends on the step which, if it's missed,

It's still a fluid though, so applying a force doesn't necessarily compress it. Think about dropping an egg into water. I wonder if you could convert all the deceleration into compression using water though.
