i think its not really a good representation of what we are looking for but the query for "number of people" yields 12854871 and the query for "number of grandchildren" yields 2191740.

'An internal document named “OPSEC”' is a very fun start to a sentence in the intellexa leak article.

We derestricted a number of vulnerabilities found by Big Sleep in JavaScriptCore today: issuetracker.google.com/issues?q=com... All of them were fixed in the iOS 26.1 (and equivalent) update last month. Definitely some cool bugs in there!

The iPhone 17 is powered by Apple's A19 SoC (System on a Chip). Chipwise took a die photo of the chip, but it's a bit drab. I spiced it up by applying the over-saturated color gradient that Apple used for die photos of the M1 chip :-) Link to the original die photo: chipwise.tech/our-portfoli...
A complex die photo with many rectangular and irregular regions. I've applied a color gradient making the photo look slightly rainbow-ish, purple and blue in the top and red and yellow at the bottom. The image has a Chipwise logo on it.

Found a video from a couple of years ago when I wrote a brainfuck implementation in Fastly VCL. Each tick of the interpreter was executed by making a GET request to the VCL service with the entire interpreter state encoded in the URL. Anyway, here is "hello world" in 1771 GET requests.

there is approximately no chance that this is a real effect, and if it is there is a 0% chance it is intentional. LLMs don't understand vulns enough to make subtle mistakes, so any intentional sabotage would be way more obvious than whatever "somewhat more apt to result in low-quality code" means.

I am just going to keep posting that the TX governor recently pardoned a political murderer. The dude texted "I'm going to shoot protestors", then went and shot a Black Lives Matter protester. He was convicted in a jury trial. Hard to find a more blatant example of celebrating political violence.

Gov. Greg Abbott pardons Daniel Perry, veteran who killed police brutality protester in 2020
A Travis County jury sentenced Perry to 25 years in prison last year, prompting Abbott to ask the state parole board to review his case.

the dumbest companies are breaking the internet. my mother-in-law lives near Stroudsburg PA and is being cut off from streaming services because the geo-ip company suddenly decided that "STH" now meant "Stockholm"... its almost like the hints geo-ip uses weren't meant to actually be relied on
a long description of how Digital Elements, a company used by Hulu to do geo-ip lookups, decided to make the abbreviations STH and HEL mean "Stockholm and Helsinki" which is locking Pennsylvania residents out of the services they pay for
