SEJeff··on New evidence for hidden chambers beyond Tutankhamun's tomb
KREE!
SEJeff··on Growing proof that autonomous cars save lives
Yeah, it is very good, but that’s only in roughly 1100 sq miles in the US. The long tail of edge cases is exponentially harder than the rest of it. They’re improving quite quickly was my point, and if anyone stands to pull it off, I’d bet on them pulling it off first.
SEJeff··on Growing proof that autonomous cars save lives
As someone who’s owned a Tesla since 2018, and was part of the early beta program, I at least have a better understanding of the tech than most random folks who don’t actually drive one daily. Also, I’m not a fan of Elon at all.

It is easily one of the best if not the top three in the world (I’m including the Chinese companies like BYD, but we can’t get those in the US).

I can say “navigate to the closest publix”, it will back out of my garage, and then drive there the whole way hands off, find a parking spot, and park.

Tesla’s robotaxi sq mileage is roughly 1100 miles vs Waymo’s 475. This is true autonomous no safety driver in the car.

So jokes aside, Tesla is leagues ahead of everyone else sans maybe some of the state funded Chinese car brands. Having actually used the tech daily for years, it’s incredible, truly.

The US is ~263x larger than the Netherlands landmass wise. It would require a loooot more trains than we have or you have.

Buddy buy a Tesla, as that’s definitely gonna happen in the medium term.

SEJeff··on Linux 7.2
Happily upvoting you for agreeing on principal with me. I shall likely join the flogging as a result.

I’m sure it will hurt my 11k internet point account.

SEJeff··on Zigbee vs. Matter over Thread:Understanding IoT Protocol Performance in Practice
Yeah that majorly sucks mate. Perhaps zwave devices just don’t work well upside down?
SEJeff··on Zigbee vs. Matter over Thread:Understanding IoT Protocol Performance in Practice
Hey mate, Z-Wave in Australia operates on the 919.8 MHz regional frequency, which is different from the US (908.4 MHz) or Europe (868.4 MHz). They have AU certified zwave kit.
SEJeff··on Zigbee vs. Matter over Thread:Understanding IoT Protocol Performance in Practice
You pay to have it tested and certified to use the trademark. This is why so much zwave kit from different vendors works perfectly where as zigbee it’s more of a crap shoot if different vendor’s gear works well together.
SEJeff··on Zigbee vs. Matter over Thread:Understanding IoT Protocol Performance in Practice
It is so proprietary in fact all of the spec is on github:

https://github.com/zwave-js/specs

SEJeff··on Zigbee vs. Matter over Thread:Understanding IoT Protocol Performance in Practice
What? The entire specification is in this git repo maintained by the home assistant team. Also, they’re on the zwave board now. It’s wholly open, but wasn’t maybe 4-5 years ago.

https://github.com/zwave-js/specs

SEJeff··on Zigbee vs. Matter over Thread:Understanding IoT Protocol Performance in Practice
Yes, zwave is in the much less congested 900mhz range. It is a fair bit more reliable as it doesn’t compete with:

- WiFi

- Bluetooth

- microwave ovens

Additionally, it’s a bit more strict with certification so you can easily use multiple vendors for zwave whereas with zigbee it’s often a terrible experience since vendors implement things differently in ways that are not as interoperable. In fact, for a device to be certified by the zwave alliance, it must pass strict conformance testing to ensure backwards compatibility and interoperability.

SEJeff··on Zigbee vs. Matter over Thread:Understanding IoT Protocol Performance in Practice
I’m a bit surprised they didn’t add zwave into this comparison.

SEJeff··on Go Experiments Explained
I’m 42, never went to college (I joined the army) and am now a Principal Security Engineer at a serious computer security firm. I’ve got a background in Linux high performance computing and software engineering.

If I can do this, anyone can. I believe in you internet friend. In tech, every day’s a school. Embrace it and learn something new daily, or get left behind. You’ve got this

SEJeff··on Go Experiments Explained
Pick a problem you’re interested in and just work on solving it, in go. The best way to learn is to hit the rough edges and just keep going.

If an oldie like me can learn go well so can you

SEJeff··on Love systemd timers
Oh yes, because the well documented clean syntax of sys v init shell scripts was so nice.

If I never recall hacking in ulimit calls in the top of buggy shell scripts for crappy old services that done respect pam_limits it won’t be soon enough.

Both use treesitter and create knowledge graphs for llm use. It results in way less tokens spent as well.

SEJeff··on Claude Opus 4.7
I believe tools like graphify cut down the tokens in thinking dramatically. It makes a knowledge graph and dumps it into markdown that is honestly awesome. Then it has stubs that pretend to be some tools like grep that read from the knowledge graph first so it does less work. Easy to setup and use too. I like it.

SEJeff··on LibreOffice – Let's put an end to the speculation
Michael Meek’s referenced blog post. The irony is I remember him championing openness for OpenOffice and I remember how transparent he was when he helped found libreoffice and TDF. What a shame we have devolved to this situation.
