How do you implement a non-backtracking NFA other than converting it to a DFA?

> Does the call to DEPTH still work in that case? Code using the braces can use those definitions when you want to remove the overhead, and it disables the feature. This lets you use it as a programming aid, and then remove the overhead

Here's why it's interesting: https://termbin.com/blz3 There you go, now it has parens, just backwards. Can even use parens instead of braces if you want, I just didn't want to overwrite comment syntax.

Maybe this is useful for real time memory management? 'arrays' for instance, if dynamically sized, can always cause fragmentation. It feels like you can get relatively efficient traversal and random access in these counted b-tre

I filled a job role that had been up for a year once, they weren't happy with the candidates until they saw me, this was in a less populated area.

I've often wondered if one reason we don't get amazing like-life paintings is because we have photos.

Yes it's worth taking a minute to appreciate how well DEFLATE and gzip has stood up over the years. It's a brilliant format and tool. I was definitely a little too ready to believe the paper that claimed gzip's ability to c

Some mail machines cut thick or oversized envelopes by accident sometimes. So this might not have been tampered with. The right way to deal with anything you receive by mail is to return to sender, as long as it has a return address. Cros

Bryan Lunduke is a tech youtuber who has occasional commentary on extreme political ideas popping up in places like IBM, and his last video was critical of Rust-as-a-feature projects. I can't help but wonder if this is what actually g

It's a build option, the variable 'tokenised' controls whether it builds tokenised or direct threaded. The macro DX outputs either a token or word depending on whether a token is available and whether 'tokenised' is

In my experience you get a lot of density moving to a variable-width font, which is quite easy to write for a Z80 system. For example I've designed a couple with the horizontal size in the first byte of the bitmap: https://g

Keeping .c and .h files separate is pointless, *.c and *.h can pick them out when necessary. 'include' is a good choice for libraries, the external interface, but not necessary for internal headers.

This is a long-needed, but gratefully accepted improvement to GCC. I've seen in the wild just how many people see a 'warning' and consider it ignorable, even though many warnings in GCC are certain indication of broken code

If I understand right, this is mandatory: void example(int n) { printf("%zu", sizeof(int[n])); } void example2(int n, int (*a)[n]) { } This is optional: void example3(int n) { int x[n]; }

As someone who doesn't know a lot about distro work, what exactly did you have to do for Fedora? Fix packages that weren't building anymore with this change?

It wouldn't have been surprising to make this the default in the 90's even. The things here are pretty much never done intentionally post-standardisation. And it's easy to force these back to being just warnings to make old b

You can still compile these by downgrading the errors to warnings. They are just errors-by-default now.
