Sorry. I implemented the current NAT system in Linux. In particular, avoiding port reservation in favor of squishing more connections into one IP address, as long as the remote address allowed us to differentiate. This, in turn, means incom

I was confused. But yes, that same Zilog Corporation as the Z80. They also did... action comics as promotional material? The final page, containing disclaimers (presumably from their standard spec sheets?) disclaiming any inaccuracy and war

Always use -Wundef. For CCAN all config vars use #if and we lint for ifdefs of them, because you have to pick a side here, and sometimes using HAVE_X in C code is useful, so I prefer always-defined.

How embarrassing! It's greatspectations.org not .com! And I can't edit the URL. Thanks, I will resubmit, and let's pretend this never happened? Eeek...

Nobody who would code this up would be entirely sane. But I can't help thinking "these are my people" when I read this...

I hacked up a (not SMP-safe!) compressed loopback driver for a now-forgotten startup's "bootable business card" rescue disk. Over a year later I received an email from someone wanting to use it who was trying to port it forw

Um, the Linux Foundation is an industry body, not a user or community group. You seem confused?

Yeah, but there's little culture of actually taking that time.

It seems that wasn't the Claude part, though I haven't seen a full analysis of exactly what broke. I also only saw one report: are there multiple, or do you just perceive that? Rsync has many options: I can totally believe that fi

For those commenting, I suggest you read the post linked by the rsync author: https://medium.com/@tridge60/rsync-and-outrage-d9849599e5a0 (Disclosure: while I haven't talked with him in years, Tridge was my collea

I'm shocked that people are jumping on one of the most productive and powerful OSS maintainers in existence. The actual Claude "churn" is mainly test suite enhancement.

"where intellectual property is not respected" This suggests to me the underlying concern is "but I won't get paid for my craft!". Hell hath no fury like a vested interest masquerading as a moral principle?

I agree: fork is fast, cheap and easy. If you're spawning something for significant work it tends to be in the noise. Linux kernel uses 8k stacks (TBH, it's been a while), but there's also some copy-on-write overhead. Still,

Adam is not Satoshi. In early days of Blockstream I remember him and Greg Maxwell spitballing ideas about Bitcoin, and he was clearly intellectually feeling out the constructions as novel concepts. I have spent my fair time with geeks, myse

As with many comments here: use a build-time assertion that the system is little-endian, and ignore it. Untested code is broken code . I was at IBM when we gave up on big endian for Power. Too much new code assumed LE, and we switched, d

In the small, it's still a meritocracy. A patch like this is obviously correct and I expect to get in first try (maybe with a formatting fix by the maintainer). For large works, the burden shifts, since you are increasing the maintenan

I share this frustration, but a downvote is probably a better reaction than a reply here.

On the other hand, I once implemented something to be told later it was novel and probably the optimal solution in the space. An AI might be more likely to find it...

A goid friend of mine worked on decimal floating point for IBM Power chips (I think it was Power 7 which had hardware support). Anyway, he insisted on calling it just "Decimal Floating". Because there was "no point".

I want signal to act as a transport bus. In particular, I want to give certain contacts permission to ask my phone for its location, so I can give my wife that ability without sharing it with Google. Signal has solved the identity part, n

I want to implement this. My code is in C. How does this help me check my implementation? I guess I could ask ChatGPT to convert your tests to my code, but that seems the long way around.

Andrew Tridgell's KnightCap did this differently: it's a network chess server, and it would dump its data to a file and re-exec. The trick here is that it would keep the (network) fds open for zero downtime. IIRC he used a Perl sc

Yes, it's terrible, and the fact that their list_add takes parameters backwards from what one might expect, with no types to catch mistakes! See https://github.com/rustyrussell/ccan/blob/master/ccan&

In recent years I've come to rely on this non-initialization idiom. Both because as code paths change the compiler can warn for simple cases, and because running tests under Valgrind catches it.
