That still breaks my head. Reaching your minimum speed slower means you have a higher speed for a longer time, covering more distance? I know nothing about racing, is it maybe about reaching a higher minimum speed by doing so before the c

You’re going to need a smidge more than that.

I disagree, hard.

Often, it's better to see the IPv6 address space as 64+a few bits instead of 128 bits, because a lot of the common ways to choose an IP address for a device defines the entire last 64 bit, so subnets smaller than /64 (i.e. prefixe

I thought it was a spot near but definitely not at the very center of our field of vision, and an ad-hoc experiment to try to find my blind spot seems to confirm that? (It seems to rather be in the periphery.) Or is there another, smaller b

One superfluous tsunami warning after an outlier 7.0 earthquake, and already "the system is training [you] to ignore it"?

No idea if that's true, but I've heard that's also why the absurd (and terrifying) seeming "children eating paint chips containing lead" is an actual occurrence. Because those lead chips taste sweet.

In San Francisco, you just call the city. They'll give you a few bottles to fill, which they will test. I remember that they even came by personally to either deliver or get them. (Or both?)

Another fair point. I think I'd use this: make restore & (make -j 20 kernel && make reset upload) But in reality, the kernel target actually calls make anyway, so it's just in there. Depends on the exact situa

Lots of things optimize for terseness. Assembly, arithmetic/algebra, and any kind of shorthand in any kind of trade. That’s because the shorthand is usually easy enough to learn, and then provides value going forward. You are perfect

Fair. But as said, in my experience, they remain useful and simple for a pretty long time. I usually always start out with a simple Makefile. Only sometimes do I start with or eventually switch to something else because of the projects’ nee

I did mention that in other comments, including the C preprocessor helping. make is completely language agnostic, so it cannot “guess” header dependencies. In make, you get the dependencies you specify (whether manual or generated), that’s

by anyfoo 2y ago
Fair!
405.
by anyfoo 2y ago
I think that's fair. On top of that, being a low level system programmer, I think I'm pretty good at realizing/intuiting when something critical changed that needs me to nuke the build dir, i.e. the manual work you mention to

I'd go further and say "parser generator", the generated parser will be compiled by a C compiler after all.

One might ask how you learned C (or python, or anything else) in the first place, if you can't be bothered to learn what the very simple $< and $@ mean, which would take you literally seconds to look up if my example wasn't act

That is neat, but also super brittle, and full of abstraction leakiness, potentially leading to both false positives and negatives. Sounds like it would break down with ccache or distcc immediately, for example.

by anyfoo 2y ago
Meh, it can practically never be perfect, without diminishing returns that at some point invalidate the advantage of any incremental builds anyway. As I said, you can let the C compiler generate your header dependencies for you. But that&

by anyfoo 2y ago
Isn’t that the same now? By the way, I dislike the term “compiler compiler”, because that’s not really what it does. I like “parser generator” for tax/bison, and “lexer generator” for flex.

Have a step that takes the SHA256 or similar of $CC, make that a dependency. You’d need slightly more advanced make features if you want to make it “pretty” (and not just, say, touch a file through some shell code comparison), but this is a

by anyfoo 2y ago
It is correct to call it an incremental Makefile, it merely doesn’t name the dependencies for you. A Makefile has exactly the dependencies you specify. It’s that simple. That is not necessarily the most useful . Especially as your project
413.
by anyfoo 2y ago
It is so trivial, it takes you 10 minutes to learn. Less even, here is an attempt: foo.o: foo.c clang -c -o foo.o foo.c This builds a file called foo.o, if foo.c is newer than foo.o. Imagine that there is an identical bar.o

Ah, thanks. My brain actually did not see that second "compiler" when reading, now it makes sense.

If you want to have "fun", generate code in a WASM-representation of Hoare's WHILE language, i.e. a program that only consists of a single outer while loop (in WASM a "loop" block), and conditionally decide for ever

I honestly don't think so, and I think this is here is a prime example for proving that. For example, a Makefile that does the same job as the build.py script in this project would be significantly smaller, simpler, and easier to read

Presumably for the same reason why we're not "just" simplifying English, which is a horribly irregular language, particularly in its orthography. We could simplify English to have similar spelling and pronunciation rules as,

by anyfoo 2y ago
The fact that the simplification stopped at time zones, and not at making one "global time zone", tells you how much you can stretch such "simplification" before it becomes a burden in other ways.

Oof. I don't know much about tubes, do they always fail in ways that are reliable to detect? (E.g. I can imagine that detecting a burned out heater is easy, but I don't know what other common failure modes there are.) And even the

Congratulations! That's no small feat.
