Comment stickmen in production can be okay (Score 2) 104

Look at the xkcd comic. In most* cases, important thing - the thing that makes xkcd xkcd - is the dialog. The drawing is literally a bunch of stick figures.

Coding can be similar. Parts of your code can be boring simplistic things that are the code-equivalent of stick figures. But if you want anyone but your "proud family" to appreciate it, it better do something interesting.

* the xkcd fans reading this - and that will be most of you - know there fantastic exceptions where the artwork is, well, fantastic

Comment Make the theif regret it (Score 2) 33

Bring a laptop that displays a GOATSE or other "MY EYES, THEY BURN, MAKE IT STOP" image if you power it on without pressing "magic keys" that enable a normal boot.

If you are worried about people stealing things for the value of the parts, equip it with hardware-self-destruct that goes off when the cover is removed (but have some way to deactivate it in case you need to remove the cover).

I see a future where travelers going to high-risk areas use laptops with everything soldered onto the motherboard AND where the motherboard won't work unless a specific device is within radio range or plugged in. Think Apple-iPhone-style "parts paring" but for laptops, and one part can go in your pocket.

from SMALLNUM lines of C and pre-processor code.

When it works well, AI-generated code is almost* just raising things to a higher level of abstraction.

* if only it were just that. Unfortunately, "vibe coding" gives you unreproducible/non-deterministic output, merely raising to the next level of abstraction should give you consistent output. It would be like compiling C code where your headers and libraries change out from under you unpredictably and with every build.

Comment I could live with rapid deletion (Score 1) 59

I would prefer not having these cameras at all. If you need to read license plates, hire people to do the jobs. If it's that important, it's worth paying for.

But that's not going to happen.

So, I can live with destroying all images within seconds unless there was an actual need to keep them, then keeping them and the data gathered from them in an encrypted, non-network-accessible location only for as long as they are needed, with strong oversight to make sure images really are deleted when no longer needed. Any supposed "need" to keep these images beyond, say, the time it takes to send out a you-didn't-pay-your-toll-bill invoice and give the recipient an opportunity to pay or protest should require court oversight.

In rare cases where the police are "on the lookout" for car matching a general description ("driver in green station wagon kidnapped small child from Springfield Kwik-E-Mart, no license plate"), keeping all images within a small targeted search area for hours instead of seconds may be tolerable, with the police keeping only those images that are useful for the investigation after the several hours have expired. In any case, keep the images offline.

In any case, keep the images encrypted and offline. I don't want some overseas black-hat group collecting a dossier of my car's travels.

How would you feel if one of these cameras was pointed at your house and the cops could access the video anytime they like?

You are confusing the police department's FLOCK camera with my across-the-street-nosy-neighbor's doorbell camera that stores data unencrypted on a weak- or no-password-required web site that the cops happen to be watching and recording 24/7.

Whew thank God Linux is a monolithic kernel with a minimal attack surface and no drivers up the wazoo to worry about.

There are ways to do just that. Minimal drivers, all compiled in. No loadable modules. Secure/trusted boot environment. Minimal access to I/O with strong input sanitization and very likely a read-only filesystem so a reboot is a true fresh start. This won't be your general-purpose computer though.

formal verification and comprehensive testing

Comprehensive testing is expensive.

Formal verification is also very difficult, but at least one formally verified microkernel, SeL4, is in production. Having a formally verified microkernel is NOT the same as having a formally verified computing environment.

but only the bad guys know about them because the code is not open for public audit

The developers may know about them but don't have the resources to fix ALL of the known bugs.

More likely, the developers are careful not to go on an internal "bug hunt" that will find bugs faster than they can fix, because someone out there will be "injured" by the one bug they prioritized as "fix later" and sue. "Because lawyers."

Comment A and B systems (Score 5, Interesting) 60

Back in the last quarter of the 20th century, many POTS telephone switches had an A side and a B side.

During software upgrades - and yes those were a thing - they would route all new calls to the A side and wait until the last call on the B side ended before they would take the B side down for the upgrade.

Then they would do some testing before bringing up the B side.

Only after they were confident that the B side was working would they upgrade the A side.

This worked in part because they could schedule upgrades when the load was low enough to be handled only by half of the switch's capacity.
