Show me a person and I'll point their flaws.

Theoretically, in this case, the agonizing "It's pouring rain, blowing cold wind in your face, kids are screaming and hitting each other, you stubbed your toe into cart and generally just having bad day" scenario making any man unable to manage the extra-harrowing effort of directing a cart a few meters into a designated space.

I already told my loved ones to stop getting me gifts for my bday / holidays a few years ago. I have everything I want that wouldn't be obscenely expensive and in poor taste to request. Whatever people got me ended up on a shelf or in a drawer and was just a waste (with a couple of rare exceptions when someone made / crafted me a gift, and then it's really wonderful).

I can't imagine how useless an unthinking AI would be at this when my own family and friends who, and this is important, _know me_, can't find anything to get me that doesn't land in the above categories. I wouldn't have expected gifts to be a source of AI resource waste, but I must not be very imaginative.

This is precisely the problem - an AI does not really "know" the recipient (set aside of what it means to "know" someone). The result is you get something just a bit more varied than the usual "He's a Guy - he'll love some Whiskey Stones, a Bacon-of-the-Month subscription, or a Beard Care Kit" advice. (Adjust for whatever target demographic.)

Acceleration by using the x86 AVX-512 extensions is especially compelling. Since ARM64 processors are becoming pervasive in server-side systems, is-there/will-there-be any optimization using the ARM64 NEON vector instructions in current or future Go versions? (The NEON instructions are 128-bit, instead of 512 bits in the AVX-512 set, but may still be useful.)

A former coworker who was a serious gun enthusiast experienced dangerously high levels of lead in his bloodstream - he had chronic headaches and other bodily pains. He visited shooting ranges several times per week, and also packed (assembled? made? I'm not sure the nomenclature) his own bullets. His doctors believe he aspirated atomized lead particulate doing so much shooting practice, and/or bullet manufacture. He underwent chelation therapy (a protocol involving taking certain medications that bind to heavy metals in the blood, and the patient excretes it out via urination) to reduce lead levels.

Noted :) In another comment I linked to beads, which is a cool project to keep your issue tracker in your repo, but that's just a personal thing, no comment on what the company plans to do (or not) in this area.

I use command-line tooling much more than IDEs (e.g. VS Code), so the `gh` command-line tool (https://cli.github.com) for doing most of the usual hub-oriented workflow (PR authoring, viewing issues, status updates, etc) really helps a lot - I don't have to constantly <cmd>+<tab> to my browser, and point-click-point-click through web pages so much. It would be fantastic if ersc or any other jj-centered code-sharing hub had similar tooling early on.

I a legitimately interested in any economic activity that reassigns your resources to my own assets, at a cost cheaper than it cost to acquire them.

Is that an appropriate legitimate interest or do we need to split hairs?

There is a difference between "giving" and "taking".

> completely impossible with printf

Not printf exactly, but I've found bugs with a combination of mprotect, userfaultfd and backtrace_symbols when I couldn't use HW breakpoints.

Basically, mark a set of pages as non-writable so that any writes trigger a pagefault, then register yourself as a pagefault handler for those and see who is doing the write, apply the write and move on. You can do this with LD_PRELOAD without even recompiling the debugee.

Back in the early '90s, I was a big fan of the C/C++ debugging library "electric fence" (written by Bruce Perens) - it was a malloc() implementation that used mmap() to set the pages of the returned buffer such that any writes in that region (and even read accesses!) caused a segfault to happen, and the program halts, so you can examine the stack. It was a godsend.

With all due respect, there are many languages in popular use that can do this, in many cases better than golang.

I believe it’s the only system you know. But it’s far from the only one.

I'd love to see a list of these, with any references you can provide.

I don't understand why, if the recipient of the initial detached "hello" is annoyed at the communication tax of having to acknowledge it before the querier gets to the real point of the convo, why in the "preferred" example, he/she responds to their gratitude ("ta") with a "np"? That seems like just as much pointless communication noise, only at the other end of the chat. When I say thanks to anyone in real-life verbal communication, their (usually a grunt) "no problem" adds nothing.

Yeah, post the company name — because I'm picturing instead a company posing was a company for the rich and famous. Do we remember The Sharper Image catalog?

antonchekhov · 7 months ago

The J Peterman catalog is still around around (at least, online) and approaches satire in its selection of goods (mostly clothing) that assiduously conveys "casual, interesting, old-money wealth". The Elaine Benes character on "Seinfeld" worked there, and had to deal with the kooky habits of the Mr Peterman character.
