SEJeff··on Officials concede they don't know the fate of Iran's uranium stockpile
And this was formally updated post 9/11 with the AUMF (Acceptable Use of Military Force) which gave the president quite sweeping powers without direct congressional approval. The caveat is that the AUMF is only for 9/11 responsible countries or affiliates. Given 9/11 was Al Qaeda and they are Sunni, and that Iran is Shia, they are not actually related since they want to also kill each other. Still, these powers are being bastardizes to limit the authority of congress.

SEJeff··on New Linux udisks flaw lets attackers get root on major Linux distros
Thomas, what are your thoughts on micro-vms such as kata containers? You can use them as a backend for docker in place of runc.

I'm sure you're well aware, but for the readers, they are isolated with a CPU's VT instructions which are built to isolate VMS. I still think "containers don't contain" in a very Dan Walsh boston accent, but this seems like a respectable start.

I can't wait to see the GIANT spoiler on the engine cowling that does nothing more than help them push it if it breaks down.
SEJeff··on The wake effect: As wind farms expand, some can ‘steal’ each others’ wind
I love the part where you all are downvoting factual replies because they don’t fit your narrative. Stay salty friends :)
SEJeff··on The wake effect: As wind farms expand, some can ‘steal’ each others’ wind
If you’re interested, here is some info about the study I mentioned:

SEJeff··on The wake effect: As wind farms expand, some can ‘steal’ each others’ wind
Modern SMRs (small nuclear reactors) can literally use spent fuel rods from legacy nuclear reactors as their primary fuel. This isn’t conjecture but simple fact. The engineering has dramatically improved even if public sentiment hasn’t. Modern nuclear reactors can not melt down in same way the reactor at Chernobyl did.

The new “fast reactors” are explicitly designed to take spent fuel rods as fuel to lessen the requirement of creating more enriched uranium.

Perhaps I should have clarified. Solar panels can not be recycled profitably, so in practice they go to landfills.

Sure there are niche recycling firms that lose money doing so, but they’re the extreme rarity vs the norm.

Here’s a nice article about it from MIT: https://climate.mit.edu/ask-mit/can-solar-panels-be-recycled

SEJeff··on The wake effect: As wind farms expand, some can ‘steal’ each others’ wind
There was a study a few years back that saw radical reduction in bird strikes simply by painting a single blade a contrasting color.
SEJeff··on The wake effect: As wind farms expand, some can ‘steal’ each others’ wind
Modern SMR nuclear reactors use precious generation spent fuel rods as their own fuel, and by design, are impossible to cause a meltdown.

I have 21.1kW of solar panels on my barn, and nuclear is still the cleanest energy at scale, but a lot. Also, solar panels can’t be realistically recycled and when the panels are done, they’re destined to landfills. At least they’re finding ways to recycle wind farm rotor blades.

By design. This is a feature, not a bug.

If you don’t care about the output or handle it manually, use detail over nohup, it’s a bit nicer.
SEJeff··on Replacing Kubernetes with systemd (2024)
Have you tried k3s? I think it would run on a tiny vps like that and is a full stack. Instead of etcd it has sqlite embedded.
SEJeff··on We know a little more about Amazon's satellites
US military gps is encrypted and heavily used FHSS. It is jam resistant, and can’t be jammed without significant expertise and know how.

Russia has some of the best EW chops in the world (after the NSA perhaps), and they struggled to successfully jam Starlink after some defensive work was carried out by SpaceX. They use Starlink in the “sea baby” USVs that attacked Crimea just last night.

SEJeff··on We know a little more about Amazon's satellites
They’ve done similar things with hundreds of cell phone cameras and digital techniques to piece it all together.

The prototype was called Gorgon Stare[1] and could surveil an entire city at once.

SEJeff··on We know a little more about Amazon's satellites
FHSS[1] has made jamming difficult in US military communications for decades. It doesn’t make it impossible but jamming the entire spectrum is nearly impossible at scale for almost everyone. At best it would affect small areas until the US sent rf seeking missiles (HARM are designed for this) at the jammer source. Also note that modern satcom like Starlink uses AESA digital phased array antennas much like a F35’s radar. It’s so much more complex than legacy analog stuff.

Starlink is neutral. Starshield is not. Starshield runs on different satellites with potential for custom additional payloads as well.

SEJeff··on Tesla suffers worst quarter since 2022 as deliveries tumble
Elon alienated the majority of the side of the political spectrum that actually can afford his vehicles. He then went on throughout Europe backing majority disliked right wing parties and utterly tanks his sales in Europe as well.

This isn't really recoverable. If the board had a spine (they don't), they'd fire him and find a new CEO.

SEJeff··on Tesla (TSLA) announces 336,681 deliveries, far worse than expected
Elektrec is Fred's blog and he went from the biggest tesla fanboi to Tesla critic the day that Elon told him to knock it off. It is in general poor opinion blogging masquerading as a news website.

SEJeff··on Dutch Parliament: Time to ditch US tech for homegrown options
The approach overall is a good one. It’s mutually assured (economic) destruction.

Dictators just don’t care however and Europe hasn’t had a ton of those since the 90s sans Putin.

SEJeff··on Dutch Parliament: Time to ditch US tech for homegrown options
Note that I said specifically dictators, and most of Europe isn’t that. The closest would be Orban and maybe Erdogan. But Hungary is seemingly a disliked minor player. Turkey is actually interesting in that Erdogan is a strong man and he’s actually really good at it seemingly. He’s also got a very modern and well trained military.

> closer trade ties lower the likelihood of armed conflict

This was 100% what Europe believed and the Merkel administration in Germany more than anyone. Not to bring politics into HN intentionally, but I think the Russian invasion of Ukraine, and threats of invading Poland, Finland, and Germany from Russian spokesmen or MPs kind of throws cold water on this theory.

No matter how well meaning you are, you can't expect dictators and "strong men" to ever act in anything but bad faith. It is time the west realizes this and acts accordingly. As an American, I'm sad to see the "de-americaning" happening due to those here who elected a bad administration, but I can't say it is surprising. Ultimately, a less weak and less dependent on the US Europe is a net good for the world. Europe collectively being able to put a check on the US forces the US to not do stupid things, so this is good long term.

It’s hard to disagree with you on that part. PG is definitely not free to get starts with and requires a bit of setup (hello pg_hba.conf).

Postgres supports JSONB natively. It literally speaks mongo line protocol and you can shove unstructured json into it.

It has supported this since 9.4: https://www.postgresql.org/docs/current/datatype-json.html
