I don't buy the idea that we have to pound the crap out of each other in a ring to prove that everyone is honest about their skills. If you want to learn anything, you definitely need to spar; but sparring is not a competition, no one

Every coder should if you ask me; I consider C, Forth & Lisp to be the brightest shining stars in PL design. Each of them offers a unique approach cut down to it's core. If you prefer a more convenient and less dogmatic approach, I

I spent some time comparing Python's [0] map/filter and comprehensions against Snigl [1]. Comprehensions are just plain faster, especially if you perform say filter and map at the same time. That and a lambda implementation that o

Regarding rotl/rotr, that was a typo in the example; they rotate the top three items left or right, I find Forths choice of 'rot' arbitrary but that may be a consequence of how the pieces fit together in Snigl. And I agree, t

All looks reasonable from here, I'll have a look tonight and see what I can do. Thanks for taking the time!

Sure thing, thanks for the help with IO stream workarounds for mac. It's a complete re-implementation to solve some of the show stoppers that Cixl ran into. Snigl should build mostly anywhere using any C11 compiler for example, so that

You're welcome :) I hear you, it's very much a crash course so far. I've tried to keep the examples nimble enough to allow decoding any foreign constructs. This is unfortunately the level I'm operating at, because it&#x2

Just noting that JIT means speculating from what you've seen so far, what I'm doing is proving invariants and removing redundancy at compile time. Which means more predictable performance, since the code stays the same once it sta

No it hasn't, because it works. Otherwise they wouldn't be forbidden in the ring, would they? There's plenty of Bullshit Do out there, no doubt. But there is also plenty of useful knowledge and experienced teachers that you m

Agreed; C, Forth & Lisp are all acquired tastes. Which is fine, one size never fits all. Just wanted to mention some alternatives to LuaJIT, since I don't think it's a viable way forward for languages of this scale. Likewise!

I do the same thing with a twist [0], since I'm not very fond of some of Lua's design choices. Lack of a decent type system, the table mess, etc. And I think Forth and Lisp make better glue languages. Can't stop smiling these

I like a lot of things about Lua, the focus on embedded use and keeping the implementation nimble among others. LuaJIT is very impressive, but it's already drowning in its own complexity. I spent the last two years more or less full ti

Sorry, still not getting it. If an implementation provides offsetof and it doesn't work, that implementation would go out of fashion in a heart beat. Where is the practical use of this information? How is this even an argument?

The best techniques for MMA, it's still a sport; more realistic than traditional boxing, but then that's a pretty low bar. I've been training martial arts for 25 years and I wouldn't put myself in there for all the money

Right :) I do hope they pay you well. Basically everyone outside of their little communist bubble know what the Clintons are all about. More power, at any cost. But it's ending any second now, mark my words. The stuff that's been

Really now? So appealing to truth and common sense is now gaslighting. Newspeak much?

Do you have any examples of methods that will get you there more effectively than practice in any discipline? Because I honestly can't think of anything.

I fail to see your point here. sgl_baseof uses offsetof with a valid struct type and a valid field name, so where is the UB? Unless you feed it an invalid pointer, but then all bets are off.
82.
by sifoobar 8y ago
The type in question is the containing C struct type. Think of sgl_baseof as the opposite of offsetof. I didn't come up with it myself of course, it's probably older than I am; I borrowed it from the Linux kernel. The other link i

I used to tell myself that our company was the exception. But in 30 years, I have yet to come across a piece of corporate software that's not crap. Established companies, consultants, startups; all crap. Different kinds of crap, it&#x2

I strongly prefer decimal fixpoints as well, despite being slower; that's what I'm doing in Snigl.

Sorry, that wasn't very clear. I knew well enough, but the system was already approaching a million lines of semi-working floating point workarounds by the time. And since it was all my crazy idea, I would have been held responsible fo

I've met plenty of coders who aren't even aware of the problem, and I spent 13 years maintaining and extending an accounting system written by people who couldn't tell a floating point issue from their ass on a good day. It&#

Just say no, that path leads to madness. C is not the right language for fancy abstractions, it will come back and bite your head off when you least expect it. It can be done, but that doesn't mean worth doing. GObject suffers from som

I prefer embedding scripting languages [0] in C. Which is another path to the same kind of compromise, with the added advantage of controlling the world for the scripting language. [0] https://gitlab.com/sifoo/snigl

I went the other way, started writing C++ in 95 and digging into C properly around 2005. Just make sure that the cure isn't worse than the disease. It's all to easy to slip into identifying with C++ because of the substantial effo
