The part that puzzles me the most was this comment about sscanf: > To be fair I had no idea most sscanf implementations called strlen so I can’t blame the developer who wrote this. Is this true? Is sscanf really O(N) on the size of the s

Does anyone know were we can find a screenshot of this new feature in action?

It can be more complicated than that, because in some circumstances increased virulence might also provide an evolutionary advantage for the pathogen. This article from snopes.com has a nice summary of the competing views: https:/&#x2

I think the question is why not rewrite just the LRU cache in C/C++/Rust (whatever floats your boat), as opposed to rewriting everything in Rust.

Not necessarily. For example, some of the more recent SARS-CoV-2 variants spread more easily because the virus causes a more severe infection, which is transmissable for a longer period of time. It's also not a guarantee that the virus

There is a race because the more people that are infected with the current strains, the more chances that the virus will have to evolve into newer strains. It is also believed that new strains are more likely to appear in places where the p

For transatlantic flights, two important "backups" are in Iceland and in the Azores. I wonder how often airplanes actually have to detour to these airports...

This article is light on the details about this being a GPL license violation or not. The final paragraph also makes it sound like Stockfish is under a permissive license (only requiring attribution) when in fact it's licensed under th

Alternatively, you can also move the gc "backwards", changing the black object. In Lua, sometimes the write barrier recolors the white child object to grey and sometimes it recolors the black parent object to grey. IIRC, the motiv

This is very important to remember. A lot of the time, the incremental GC is still single threaded. The difference is that while a two-color "stop the world" algorithm has to collect everything in one long GC pause, the three-colo

For more context, Derek Lowe recently wrote a very interesting blog post about this drug: https://blogs.sciencemag.org/pipeline/archives/2021/02/15/gl... This is not a miracle drug. It needs to be i

In this particular case, the append and join version which is the fastest in CPython is also the recommended way to do it in PyPy.

I agree with you that newer versions don't tend to get rid of optimizations. However, other python implementations might not optimize the concatenation. IIRC, pypy doesn't.

I remember watching a presentation by Tanja Lange and djb that explained that kind of thing very well. It starts with easy to visualize examples using "clock crypto" and then transitions to real ECC curves. https://medi

The question I had is if it shouldn't be using some kind of *= instead of +=, so it's amortized constant time.

Today I learned that getline is technically part of POSIX now. Does anyone know which libcs implement it, in addition to glibc?

I think this is not what the parent poster was saying. The problem of bitcoin is not one of induced demand, where cheaper goods means that people become willing to use it less efficiently. Difficulty adjustment is as if every car monitored

Even renewable energy has externalities. They're not as bad as burning fossil fuels but we still want to avoid wasting energy on inefficient things.

One thing I prefer about Mercurial is that it doesn't have a separate staging area. To create a new commit in git you need to run `git add` followed by `git commit`. In Mercurial it's just `hg commit`. Furthermore, if you want to

Do you know what this flag considers to be a "valid" control flow transfer? The documentation makes it sound that this feature can safely be enabled all the time. But the linked article suggests otherwise...

On the matter of PPAs, these days I find that most of the things I used to use third party repos for I can now get as flatpaks from flathub. Really helped cut down on how many third party repos I'm using.

The parseInt bug that's mentioned in thd article is very likely to catch you eventually if you use Javascript for long enough. The habit that I developed as a response to that is to always pass a lambda to the callback. That is, write

Another advantage of the oral vaccine is that it produces better immunity in the gut, which helps cut off assymptomatic transmission in places where polio is still endemic.

A recent attempt at a dengue vaccine faced a similar problem. The most dangerous kind of dengue fever happens when you are infected a second time, by a different variant than you were infected the first time. It turns out that the vaccine e

By the way, if you scroll all the way down in the "Docs" page of the website there are links to older articles about the early history of Gobolinux. Some interesting discussions about the design of the Unix file system hierarchy.

I have a friend that uses GoboLinux. It's not a mainstream distro but my friend did seem able to hook it to the overhead projector without problems, so it works well enough from at least that point of view :)

When they thought us about it in school they said that the most common problem of a severe infection is that it can cause anemia, because the adult worms feed on blood in the intestines. It can be prevented by using shoes and not walking ba

These ones do not. You might be thinking about pork tapeworms.

Hookworms are a serious health problem in many parts of the developing world. If they manage to create a working vaccine it might be a game changer!
