But I gotta hand it to AI labs that "WE MUST BE STOPPED AT ANY COST OR WE'RE GOING TO KILL YOU ALL" is one of the most original marketing pitches I've heard in my life

BREAKING: due to ongoing safety concerns, we decided not to release this account's latest toot. During testing, the toot scored dangerously high on insight and humor benchmarks. Following the completion of additional safety testing, we'll release a less insightful version of the toot

Worried about AI? Don't be. Using agents at work simply empowers you to focus on more meaningful tasks, similarly to how self-checkout allowed cashiers to pursue higher-impact projects at the grocery store

How to tell which platform you're posting on: 1) If you get unhinged responses from NFT / crypto / AI bros, it's Twitter, 2) If you get unhinged responses from communists, it's Mastodon, 3) If you get no responses, it's Bluesky

And to be clear, I don't judge what people do in their own time, but when you invite your congregation to an orgy in the congregation's compound, you kinda-sorta have a sex cult.

Not exactly fine furniture, but a simple utilitarian bookshelf for my wife's workshop. The lumber is local birch, the back part is to prevent sagging in an otherwise open-frame bookshelf.

More seriously, the attached image - my 90-day stats from Google - really shows that if you like an author, you gotta subscribe. For non-commercial stuff, discoverability via search is more or less dead. Social media posts on most platforms are on average shown to <5% of followers unless one pays for "boost". It's pretty much down to email or RSS.

I put together a short page with a selection of blog articles that never made waves on social media, but that I think are interesting. It’s mostly a monument to my saltiness, but if it's a slow weekend for you, it could be a good way to to kill time: https://blog.coredump.cx/p/regrets
blog.coredump.cx

“Regrets”

This is a selection of articles that I’m fond of but that have never gotten far on Hacker News, on social media, or in Google search results.

Did you know that before LLMs, people sometimes actively sought "knowledge" and turned to so-called "books"? If you want a sense of how our ancestors lived, "The Secret Life of Circuits" is shipping in just a few weeks: https://lcamtuf.coredump.cx/electronics/ ToC & sample chapter included.

I tempted to do a small giveaway: reply with your best success *or* horror story related to electronics. I'll pick ~3 winners around EOW and send them a copy of The Secret Life of Circuits. Plz no AI slop. Won't ship to Russia.

@adamshostack@infosec.exchange Google increasingly only returns obfuscated URLs that need to go through their infrastructure to navigate to the target. So they get a true count for clicks for these users. But even if you're getting raw URLs as a signed-in user in good standing, it's what... let's say that 50% of tech-savvy users have ad blockers. These numbers don't look better if you multiply them by 2...

On occasion, I delete old blog posts; it's almost always current-event punditry. These posts have two possible outcomes. You were wrong and look dumb. Or you were right, and two years later, everyone "has always known" what you're trying to say and you look dumb anyway.

re: LLMs: funny, but also kind of sad.
@nothacking@infosec.exchange As to your second question, yes; I did see (and delete / hide) a couple of obviously LLM-generated comments and emails that seemed to be conversation hooks vaguely related to the article. I didn't bother responding because I'm 90% sure that what would have followed is an attempt to sell me something.

PSA: if you read my blog via a web-based feed reader, be aware that Inoreader and Feedly fetch once and never update their copies. I regularly make substantial updates published articles, so if you're using these tools, you're getting a subpar experience. The Old Reader is fine.
