The article doesn’t really tell us what is gained by rejecting infinity. And in general, why not also reject zero, negative numbers, irrational numbers, complex numbers, uncomputable numbers, etc.? Seems like an article about quacks that ca

Reminds me of around 2002 when MS slapped “.Net” onto everything.

Yeah but to the commenter I was replying to, I don't think it was clear that detail was relevant to the benchmark numbers they were quoting.

by bmenrigh 7mo ago
No, the gains here aren't very dramatic when compared properly (against fsync), and have nothing to do with AI help. The gains come down to Linux kernel support for certain synchronization primitives like the Mutex on Windows, such tha

Those benchmark numbers are slightly misleading, as they are a comparison of Wine+ntsync against Wine+nothing. There has been a somewhat fast "fsync" library built around Linux's futex and the gains over Wine+fsync are modest

I don’t fault Quanta (or 3b1b) for being the way they are. Each is serving their goal audience pretty well. My compliant is only that there should be a dozen more just like them, each competing with each other for the best, most engaging ma

Modern x86_64 has supported multiple page sizes for a long time. I'm on commodity Zen 5 hardware (9900X) with 128 GiB of RAM. Linux will still use a base page size of 4kb but also supports both 2 MiB and 1 GiB huge pages. You can pass

I recently started using Microsoft's mimalloc (via an LD_PRELOAD) to better use huge (1 GB) pages in a memory intensive program. The performance gains are significant (around 20%). It feels rather strange using an open source MS librar

Yeah I don’t get it. Shifts and rolls are among the simplest of all instructions to implement because they can be done with just wires, zero gates. Hard to imagine a justification for leaving them out.

My main skepticism here is whether the theorems have been properly replicated in the proof. Verifying that the proof really captured the mathematical statement seems like a manual, human process, and quite hard to repeat reliably across pro

Yeah I learning about LPCAMM2 memory was far more interesting than the repairability score.

Oh completely. But my perspective is that we all should individually punish clickbait by not clicking. More broadly, we should strive to keep HN full of quality tech content rather than clickbait.

by bmenrigh 8mo ago
"better", "more accessible"? What the hell are you talking about? Clickbait doesn't make anything better or more accessible. Instead, it makes it impossible to pre-select for interesting information. Instead of tell

Can we stop it with "and the results are terrifying", "and you won't believe what I found", "the <x> situation is insane", etc.? The over-hyping of low quality, low effort content is making it hard t

I love the AVX512 support in Zen 5 but the lack of Valgrind support for many of the AVX512 instructions frustrates me almost daily. I have to maintain a separate environment for compiling and testing because of it.

I ran my own XMPP server for about 15 years. Then 10(?) years ago Google's GChat migrated away from XMPP. I never had another XMPP conversation with anyone from that point on. I finally turned the XMMP daemon off off about 2 years ago

Often "nothing is changing" ends up being more literal than the founders realize or intend. Acquisitions by big companies tend to slow the development to a crawl as development bureaucracy takes over. When a great product is pract

Yeah I've spent way too much time reading this "guy's" posts here, Academia profile, etc. Huge waste of time. AI has managed to amplify a crank 100x. This is only going get worse.

Charles Schwab has something very similar. They keep unenrolling me from their paperless thing and then send me a letter every month telling me they unenrolled me because emails aren't being delivered. But I get their emails just fine.

A lot of people want to slap licenses on things without really thinking about what the license will do (or prevent), in practice. I like the author's note about the license: "As we do not believe in imaginary property, this packag

The goto tool that practically anyone doing any DNS tunneling uses is dnscat2 ( https://github.com/iagox86/dnscat2 ). It works fine through recursive/forwarding resolvers because those resolvers must recurse out to

Your pentest scenario where you have an internal host without outbound access is an entirely different situation than what this SOCKS masquerading as SMTP code addresses. The posted code can't speak SMTP to an internal server and hav

Large volumes of SMTP-like traffic are a huge red flag. Competent companies an ISPs should already be looking for large volumes of outbound mail to identify abuse / spam bots / data exfiltration. If I came across this in netflow d

There are so many problems with this article and the previous one it references (How weak passwords and other failings led to catastrophic breach of Ascension). Specifically, RC4 is a stream cipher. Yet, much of the discussion is around the
