It can be simpler to not make a finite state machine. Instead, try the different alternatives one by one, the longest one first. Instead of if (next == '>') { advance() if (next == '=') {

I also use it to stream videos, not just for downloading. I can watch using a native video player (such as mpv) instead of the web interface. More control over the playback speed and less buffering when I pause or fast forward. Very useful

I have to confess that this EWD on 0-1 indexing is one of my pet peeves. Whenever the topic comes up, someone will invariably link to it uncritically, even though Djikstra's argument is biased in favor of 0-based indexing. For example,

Thanks for investigating that! An accumulator is when we add an extra parameter to hold the "loop variable", like this: bool doit(int n, bool acc) { if (n == 0) return acc; else return doit(n-1, !acc);

I'm very curious how it optimizes that recursive version at the end, because it is not tail recursive. Does anyone know? Perhaps it becomes tail recursive after one round of inlining?

It's not the only place where this terminology confuses people. Another one is "register-based virtual machine", in the context of interpreters. In that case the registers belong to the VM and are actually stored in stack me

I'm convinced that I'll eventually need a name for this inevitability. Rachel's Law of Root Exploits?

The C standard doesn't mandate tail-call optimization, but at least GCC and Clang are pretty good at doing it (-foptimize-sibling-calls, which is turned on with -O2)

The arithmetic if might be one of the best examples of how structured programming has become the new standard. In 1960, it was the only way to do "if" in the most popular programming language that existed at the time. Today, I bet

The problem is that it is cheaper to produce hydrogen using fossil fuels, instead of using clean energy + eletrolysis. https://en.wikipedia.org/wiki/Hydrogen_production > As of 2020, the majority of hydrogen (∼95%)

It might have been worthwhile to include a discussion on how to safely escape the shell strings, in case there is no API that receives a list of arguments. On Unix, it is not very intuitive because you cannot use backslash inside a single q

Like the parent poster, when I read the article I assumed that there was no conceivable reason to ever use this feature in a real C program. Let me just say that I'm pleasantly surprised to be proven wrong!

Sometimes I with that intro to compilers books placed a bigger emphasis on recursive descent. Recursive descent works anywhere, without dependencies to external tools such as Bison or ANTLR. I hope that this book marks the start of a trend.

It certainly is confusing. I remember that someone once made a video with the flipped map and most of the comments were about how weird it appeared: https://www.reddit.com/r/DotA2/comments/5rmbd3/ Howeve

Nevertheless, I think we can all agree that the olympics should have picked a less confusing acronym for the Russian athletes.

One funny example of this is that thyroids are described as being butterfly shaped. Maybe endrocrinologists need to talk more with the entomologists. :)

I think the parent posted was referring to also uploading a preprint of the paper to your website, in addition to submitting it to a prestigeous journal.

I'll take this chance to ask a fork bomb question I always had: on Linux, is there a way to stop a fork bomb once it gets going, other than turning off the power?

On Github the workflow we use for this is rebase in the command line and then press the "Create a merge commit" button in the web UI.

by ufo 5y ago
In my organization we kind of do this. We use one merge commit per pull request, without squashing. However, we also rebase before merging, which results in a commit graph that looks like a cactus: o-o-o o-o o-o-o /

One small thing I prefer about neovim is that the default settings are better. For example, syntax highlighting is enabled. https://neovim.io/doc/user/vim_diff.html#vim-differences

I don't see a problem with the information being available. But in my opinion it shouldn't be in the headline. IMO, it would be better if the headline just said that the vaccine is safe and effective.

by ufo 5y ago
I'd say the opposite: maybe the news reports should have less detail. The efficacy percentages of different vaccines mean different things but the way they have been publicized has lead many people to think one vaccine is better than t

Not at all! Bitcoin is not just inefficient, it is purposefully inefficient on a colossal scale. By design, all the energy is turned into waste heat.

By the way, I recommend using `push --force-with-lease `instead of `push --force`. This way it doesn't destroy the remote changes if someone else pushed while you weren't looking.
