That is a very neat trick indeed, I'll have to remember this one!

Yeah, if Apple says "This is our official package manager, and you can use it to install OpenSSL/nginx/whatever", like or not, they are on the hook if it breaks, and they have to fix it. Like, companies are going to be l

I mean, I don't run any billion dollar companies, so what do I know, but Apple donating a couple of million to ensure that Homebrew stays active seems like a no-brainer investment to me. Yeah, Homebrew has been doing this work for free

I thought it was like the compiler flag, -O3. ”With full optimization”, basically.

Now I suddenly wonder what sarcastic assembly looks like! XOR swaps instead temporary variables everywhere? Jump tables for simple if/elses? Moving the stack pointer up and down for no reason, just because you can?

I generally don't like the "steve is typing" notifications that all modern communication apps ahve (it's the weirdest feeling is seeing one of those and then see it disappear without the person sending a message), but fo

It happens occasionally. An example would be that there are a couple of libraries that do "generic collections" in C using the preprocessor (instead of using templates). So, you could imagine something like this: #define VEC

It's blows my mind that something like this hasn't been in the standard library for, like, 20 years. Like, why can't i do this? std::string str = "Values: "; for (auto &[key, val]: dict) { str.ap

This is another excellent reason for using ledger: you are in total control of your financial data. It’s just text-files, you don’t have to share them with any service, they are not in some weird binary format, and you can use standard tool

The file format for ledger is very simple, it's literally just a list of transations formatted like this: 2021/01/12 Grocery store Assets:Checking Expenses:Groceries $50 This transaction means th

I can really recommend doing this for your personal finances! Tools like ledger are really powerful, and properly accounting is a great way to save on money. I can very easily go into my personal ledger and (say) get a report on "How m

There is no way to eliminate these doubts. If you made a magical cure that totally eliminated the bacteria that causes Lyme disease, then these patients would take it, and it would almost certainly not work (because "chronic Lyme"

Multiprocessing and parallel programming is a different thing from async/await, which primarily has to do with with green threads and coroutines. You're right that the ideas go way back (hell, Knuth was writing about coroutines in

Of course you can, you just add a record whenever you do the jump, exactly like what you’re describing with inlined calls. It’s not hard to implement, it’s just that nobody does it, because it’s dumb. You seem to have a very Java-centered v

So you’re saying inlining doesn’t count as an optimization, then?

How does it change the semantics of Scheme? It avoids blowing the stack for sure, but the stack size isn’t part of the semantics of Scheme. If you imagine a computer with arbitrary amounts of memory, then the language behaves identically wi

What about California and Hawaii or Alaska then? Where do you draw the line?

Does this cache build artifacts in any way? So if several developers are working on the same code-base, they can share build artifacts based on, like, the hash of the inputs? That would require reproducible builds, but that's probably

> Adding “auto” is just a me-too to the “var” of C# and Java. I get the "C++ is so full of nonsense, and they keep adding more of it!" attitude, and I largely agree with it, but "auto" is a bad target. auto makes a lo

I always found it surprising that Java implemented method overloading, but not operator overloading for arithmetic/logical operators. It's such a useful feature for a lot of types and really cleans up code, and the only real reaso

Of course you can always use an intermediate file, the point is that sponge is a very convenient way to just do it in a single command, without having to use intermediate files. You don't have to use pipes either, you know. You can jus

> There is no reason in principle why a shell could not implement digital signatures. They currently don't, though, which is the point :) The reason in principle this might not work is that different distros and os's trust diff

Not easily, and probably not in a way that would work on all different systems (different distros/os's trust different keys).

sponge rules, but you need to be careful. Lets say you wanted to search/replace a file with sed and sponge, then this does not work: cat file.txt | sed "s/a/b/g" | sponge > file.txt Because bash open

Binaries we download and run (as well as packages from package managers) are generally cryptographically signed by people you trust. Shell scripts you curl into bash are not. It is generally MUCH easier to compromise a website and insert yo
