jkestner··on Developer gets Half-Life running at 30 FPS on a Nokia N95
Tell you what though, I would jump on a modern N95. I only really want a basic phone with a good camera, and sure, Python. Only need LTE and a thinner form factor.
jkestner··on Apple Watch for Your Kids
I'm thankful I live in one of the several states with "free range" laws to protect parents from this. https://letgrow.org/states/
jkestner··on SpaceX, Other Mega IPOs Denied Fast Index Entry by S&P
The valuation is actually mostly about AI. Satellites, like electric cars, don’t have quite the growth story (and I do mean “story”).

jkestner··on My Students Can't Read
Something something about metrics ceasing to be a good measure. Texas has draconian measures for districts containing a failing school, even as they redistribute the majority of funding from cities to rural districts. No surprise the schools want to pass by any means.
jkestner··on I'm Tired of Talking to AI
I'm ramming my head against a wall in sympathy.

Interesting that the boss immediately asked the same question. So they're aware that AI gives nondeterministic answers and yet still use it.

jkestner··on Is "colorectal cancer" rising in "young people"?
I had to start getting colonoscopies ahead of schedule because my dad never did, until it was too late. He was scared of doctors after he associated them with family members' unpleasant deaths.

Read the safety statistics and let it override the anecdotes. Colon cancer is easy to prevent and a horrible way to die.

jkestner··on Is "colorectal cancer" rising in "young people"?
Might try that this time. OTOH, I get the greatest nap of my life shaking off the sedative (get the lighter, cheaper option like Versed instead of anesthesiologist-administered propofol) and my spouse makes me a milkshake.
jkestner··on CBP Directive 3340-049B: Border Search of Electronic Devices
And Lake Michigan, as it’s connected to international water. Suppose next they’ll claim all rivers as borders.

jkestner··on The FBI Wants to Buy Nationwide Access to License Plate Readers
If Shot Spotter is bad at merely identifying the source of a gunshot, I'm not going to trust our security tech bros to cut through all the environmental noise and provide trustworthy identification among 10,000 different Teslas.
jkestner··on The FBI Wants to Buy Nationwide Access to License Plate Readers
I'm guessing license plate takes precedence over all those things. On the other hand, Flock hasn't shown any particular competence, and is happy to flag a bunch of false positives (look at all those criminals!).
jkestner··on The FBI Wants to Buy Nationwide Access to License Plate Readers
Note that Flock says it can identify a car by physical characteristics from dents to bumper stickers.
jkestner··on At least 25 Flock cameras have been destroyed in five states since April 2025
> Violence is not the answer.

Okay, but what about destruction of property?

On voting harder, see the lead incident mentioned: "This happened weeks after the city council voted to keep the cameras despite overwhelming public opposition." I also advocate patiently working through the process, but people are not blind to the trends: the democratic process is failing as government increasingly sidelines voters and the richest have the levers of power.

jkestner··on Americans Are Smashing Flock Cameras
AirTag but for dashcams would be cool. The trick is to make a popular product without being a company that's going to gatekeep that data.
jkestner··on Killed by Apple
And Michael Spindler’s mental health. https://lowendmac.com/2013/michael-spindler-peter-principle-...
jkestner··on Killed by Apple
I dunno, I hated how the Apple ][ forced a case on you. Had more choice before.
jkestner··on Louis Rossmann offers to pay legal fees for a threatened OrcaSlicer developer
The hackers did the work for free upfront. In return they only expect that everyone could share the fruit.
jkestner··on Poland is now among the 20 largest economies
Chicken and egg. How did those voters get that way? Some governments and rich people fund sock puppets to influence our national discourse, to muddy the truth if not outright spread lies. They wouldn't do it if it didn't work.

But sure, sock puppets also follow the crowd. Good money in it: https://www.bbc.com/news/articles/cj38m11218xo

jkestner··on Casio S100X Japanese Lacquer Edition (JP Page Only)
Tools and Toys, or Uncrate, might have started out like this but seem to be more platforms for “brand stories” and just fresh new luxury gadgets. If you start a blog like this to fill in the gap, I’ll follow!
jkestner··on Poland is now among the 20 largest economies
I wonder how many of those accounts are sock puppets like we have in American social media.
jkestner··on Pulitzer Prize Winners 2026
Aaron Parsley's account of the Kerrville flood in Texas Monthly is deserving. A waterline-level personal account that makes a disaster real. https://www.texasmonthly.com/news-politics/texas-flood-first...
jkestner··on Pulitzer Prize Winners 2026
But thanks to the visibility Torre has given it, it'll be a lot harder for the NBA to go light on them.
jkestner··on He asked AI to count carbs 27000 times. It couldn't give the same answer twice
Here we’re at the origin of the tool and get to watch how many people hit themselves in the head before we learn this collective wisdom.

There’s a gap between what the tool will allow you to tell it to do, and what it’s good at. The feedback mechanism to tell the difference is deficient compared to a hammer.

jkestner··on Work with the garage door up (2024)
I get most people don’t want to fight that perception, but it’s an opportunity to educate people on the process, and if enough people do this, it normalizes the idea of people working on things, instead of the idea that products are delivered from the heavenly forges of big tech.

It’s something I admire about the best Kickstarter projects, and the framing that the platform has provided (even if it’s marketing facade now). You post regular updates about what you’re doing, you resist the urge to look perfect, you demystify creation. I think that’s kind of important for society to trust how our modern world was made, too.

My kids are going to have an advantage in making things from scratch because they simply witness me doing it.

jkestner··on Trump fires NSF's oversight board
This should feel personal to a lot of us. I have hopes of applying to the Small Business Innovation Research fund (https://seedfund.nsf.gov), a program that gives small companies a good chunk of money without taking equity, in order to encourage development of technologies deemed of national importance. I’d be curious if anyone here has tried applying in the last 18 months.
jkestner··on Trump fires NSF's oversight board
You don’t think it’s worth it to research this yourself. That’s what the NSF is for, on a bigger scale! LMGTFY: https://www.nsf.gov/impacts
jkestner··on Girl, 10, finds rare Mexican axolotl under Welsh bridge
Any self-respecting Aztecophile. They're also the cause of startup names dropping a vowl. Insufferable.
jkestner··on A programmable watch you can actually wear
http://supermechanical.com/pickup Been in production hell thanks to tariffs (wrote a lot about it) but should ship by summer.
jkestner··on A programmable watch you can actually wear
Different use case (environmental data recorder) but our current product uses an STM that turns on an ESP32 (not trusting that sleep mode) when it needs radio, to run on 2 AAs forever.
jkestner··on Bodega cats of New York
True. It's unconscionable to give a cat access to cigarettes.
