You've never see an old vehicle blow a substantially "bluer than normal" cloud. That's what I'm talking about.

> Blown gaskets on ICE engines like E25s leak both oil AND coolant, no?

This is way, way too broad of a statement. The Subaru EJ25 tends to leak oil externally from the valve covers. When they have head gasket problems it tends to be combustion gas into coolant which blows the coolant out the expansion tank until equilibrium is reached. Typical head gasket failures cause some degree of that but coolant mixing with oil is more typical. Many V engines have intake gaskets that can leak coolant into the intake or oil or both.

Regardless, if you can taste coolant in the exhaust the car is basically at the point of "fix it now"

> I might be mixing up blown heads with cracked manifolds which often go hand in hand since temp extremes in engines fissure cast parts like the manifold.

A sizable minority of cars don't even use cast manifolds anymore. While it's possible for cast manifolds to crack in a way that makes them leak that's rare and it's more common for them to crack their mounting tabs off. Steel exhaust tubing can and does sometimes break after many years of vibration, say nothing of rust.

While cylinder heads can crack it usually takes the kind of overheating that requires major work to fix in order to make it happen so just about nobody is driving around with a cracked head.

> The Islamic theocracy in charge of Iran is deeply unpopular due to its repression and severe mismanagement of the Iranian economy

Here's a way of saying that in a less propaganda'y way: "The Iranian government is unpopular because of the impact of US sanctions, which have made the lives of ordinary citizens mucher harder than they need to be."

> It has cut Iran off from the Internet

Because foreign-backed terrorists were using Starlink terminals to communicate, and the security services needed to find them, and stop them; at least, that's what Iran claims, and it at least makes sense.

Hi,

My name is Matthew Burns. I am an MIT Grad who runs an electronics product design firm. I work with startups and product design firms, and I am currently subcontracting from and am the electrical for 3 PD firms across the country. I have a lot of design experience in the PD world and have been making boards since I was a kid. I would love to design, and / or reverse engineer your wheelchair electronics. Whether it be more accessible parts, clearer supply chain, acquiring firmware / hardware that is your IP and not opaque to change, adding capability, or doing cost reduction.

I have completed a number of motor and controls projects including robot grippers, electronic transportation carts, and more. You can view some of my professional work online at:

www.burnselectronics.com

You can also view my personal work at:

www.bunch-of-electricals.com

I'd love to help. Let me know if there is a good time to chat.

Thanks,
Matt

Paradox of intolerance answers your dilemma.

Other answers: if placebos work, why would we restrict peoples choice and their dissemination?

Because placebos rarely are innocent in often they become avoidant measures away from empirical science.

Your view point is a local minimum in that you want to ignore societal impact. One of those impacts is using valid data to tout pseudoscientific methods.

We know GIGO but the general populace does not

You should use the samw logic ans find yourself arguing against vaccinea and herd immunity.

Based on reading https://developer.nvidia.com/blog/record-breaking-nvidia-cuo..., we are honestly pretty similar in terms of technology choices and (verifiable) performance. NVIDIA's found a few new records on VRPTW and pickup-and-delivery problems; but so did we in May and June 2023: https://galgos.inf.puc-rio.br/cvrplib/index.php/en/updates/. We have stopped playing the benchmarketing game, but if PyVRP ran for a few hours I'm sure we could find new records on (some) instances again. And we only need commodity hardware to do that, not beefy GPUs.

The NVIDIA article mentions constant time move evaluations using time warp inside their local search. We use the exact same thing. We used to have a genetic algorithm on top of the local search, like NVIDIA, but recently dropped that in favour of iterated local search, because we found that to be stabler, converge faster, and overall easier to reason about.

I think NVIDIA has a great product, and an even better marketing department.

Much of it is tax farming, e.g. parking permits and entry fees. In other places, councils pedestrianise space so that they can set up their own funfairs and Christmas bars etc in competition with local businesses.

I do not own a car right now, but I don't see much evidence of areas becoming more economically active, except in tourist traps. A lot of businesses and even retail has moved online or out of town to deal with rates. Most of the town centres round here I have seen are deserts filled with vape shops, tanning salons and hairdressers/barbers.

As I say elsewhere this is not just a city problem but a rural one. At my old home I would have to walk several miles to catch a bus which would appear several times a day. The majority of country areas here are not well served by buses.

I agree that it is unnerving, but I expect it to be normal in the future. They save a bunch of time by being able to push out a 90% product with low risk of catastrophe and just push updates later to fix it up. As a bonus, they can market the frequent updates as a benefit rather than cleaning up technical debt they would have had to iron out before shipping the first car.

Light bulbs (including LEDs) are similar. If you use them at slightly lower then their maximum rating, things tend to last a LOT longer. The "Dubai lamp" uses this concept - oversized LEDs that are derated, and last a very long time (100k hours). You can do the same by buying oversized dimmable LEDs and simply turning down the brightness.
Show HN: Root – Privacy-preserving home security camera
by PaulPlay | 2026-01-25 17:27:51+00:00
Hey Hacker News!

The past few months I’ve been working on this open-source software stack that makes it easy to build your own privacy-first security camera. When searching for a security camera (e.g. Google Nest, Amazon Ring..) that guarantees privacy I was surprised to find out there’s no such option, apart from going the old-school route. Many of the big players also had major privacy scandals.

It has gotten even worse over the last couple of months with Amazon Ring now working together with Flock Safety, a company helping law enforcement with mass surveillance.

Using the ROOT software stack you can set up a feature-rich & remotely accessible security camera with on-device AI vision in no time. No need for a big NVR, home server, etc. All communication is fully end-to-end encrypted (with forward secrecy), and recordings are stored locally.

The linked guide walks you through the easy process, all you need is a Raspberry Pi Zero 2 + a camera module. I’m also currently working on a hardware prototype to make this even more accessible :-)

Happy to answer any questions!

A core piece of wisdom in chemical engineering is that anything is possible with sufficient energy. Fresh water being available in any particular part of the globe is the kind of classic thermal (read: energy) and mass transport problem that chemical engineering is all about.

Increasing energy production buys a lot of optionality when solving these kinds of physical world problems. It allows you to solve problems by throwing energy at them. It may not always be the most theoretically efficient solution, like throwing hardware at software performance problems, but it may be the only practical solution.

For this reason, it makes sense to build as much power generation capacity as possible even it isn't entirely clear what it will be used for. The inability of the developed world to massively scale power generation is the true environmental failure but people don't grok second-order effects.

Most if not all of their attacks are inexcusable. Calling a competing OS, CalyxOS, nazi sympathizers is unacceptable and when I first read that I started seeing the red flags.

Nothing is open about GrapheneOS aside from the source code. We officially know nothing about the leadership, their current plans, what their finances look like or even who this new mysterious OEM is.

This is far from the only alternative. There are also Mobian, PureOS, postmarketOS and more. Unlike Ubuntu Touch, they allow you to run ordinary Linux desktop apps. Also there is hardware not tied to an ancient Android kernel, designed to run desktop GNU/Linux: Pinephone and Librem 5. The latter is my daily driver.

That's a misunderstanding. There were plenty of ancient and medieval translations of the Bible, but the Bible itself wasn't as central as it is today.

Catholic and Orthodox Christianity do not focus as much on the Bible as Protestant Christianity. They are based on the tradition, of which the Bible is only a part, while the Protestant Reformation elevated the Bible above the tradition. (By a tortured analogy, you could say that Catholicism and Orthodoxy are common law Christianity, while Protestantism is civil law Christianity.)

From a Catholic or Orthodox perspective, there is a living tradition from the days of Jesus and the Apostles to present day. Some parts of it were written down and became the New Testament, but the parts that were left out were equally important. You cannot therefore understand the Bible without understanding the tradition, because it's only a partial account.

So one thing I only recently figured out is that using ChatGPT via the web browser chat is massively different from using OpenAI's code-focused Codex model / interface. Once I switched to using Codex (via the VS Code extension + my own ChatGPT subscription) the quality of answers I got improved massively.

So if you're trying to use LLM to help with debug, make sure you're using the right model!! There are apparently massive differences between models of the same generation from the same company

> White House Deputy Communications Director Kaelan Dorr defended the post after criticism of the image manipulation.

The banner image on Dorr's X account reads: "oMg, diD tHe wHiTE hOuSE reALLy PosT tHiS?"

You're right, and I'd add that the agenda goes well beyond muddying the waters. This administration is deliberately normalizing bad faith, lying, and trolling. Discrediting critics as humorless, pathetic pearl-clutchers. I don't believe that their supporters strictly "believe" in Trump's alternate reality - they know that Trump and his cronies lie non-stop, and they like it. Accepting these lies serves as a shibboleth and lays the groundwork for discrediting fair elections, bogus prosecutions of political opponents, and everything else this administration is doing to corruptly hold on to power and demoralize their opponents.

Of course. I actually think that "we did everything we reasonably could have" or "doing more would be financially disadvantageous for us" are acceptable conclusions for an RCA. But it's important that such a conclusion is arrived at only after rigorously following the process and making a genuine high effort attempt to identify ways in which the system could be improved. You wouldn't be performing an RCA if the incident didn't have fairly serious consequences, right?

It could also well be that Joe did the same thing at his last employer, someone in hiring happened to catch wind of it, a disorganized or understaffed process resulted in the ball somehow getting dropped, and here you are.

Lol the CEO of Palantir said enthusiastically during an investor conference that it's necessary on occasion to kill his enemies, why would you think tech reputations would get torched? If anything it should be a boon when getting hired for big tech. As the government becomes more fascist and more integrated with industry, these contracts will be more and more important and enthusiastically embracing the anti-domestic-terrorist line will improve reputations even more.

It very much depends. These days most apps are developed so that they’re equally trash on both.

The apps that are more specialized to reach OS tend to prioritize iOS because if you look at app revenue, iOS users wildly outspend Android users. At least this was true when i was doing mobile shit a couple years ago

That doesn’t mean the android app sucks, but it’s usually given lower priority. New features and updates will usually hit iOS version sooner and things like that

There is a difference between not liking someone for substantive and non-substantive reasons. I have military training that is adjacent to policing because that was one of the objectives of the theater I was in.

Informed by that training I would never:

- shoot someone when they are being detained

- shoot someone simply because they have a gun

- stand next to a vehicle so as to postulate the vehicle as a weapon

When I don't like Kristi Noem it isn't because she's Kristi Noem, because she's a woman, or because she shot a puppy she didn't like. It's because her actions and policy that she defends and writes don't agree with the ethics of the training I received.

You can do this thought exercise across this administration and arrive at the same conclusions of most of the key-holding individuals.

Years ago I did a lot of driving around rural Latin America and it could not have been more different from a US city. Official traffic rules were almost non-existent in many areas but the informal ones that had evolved worked shockingly well. Like a cramped two way street might only have room for one car in spots, but there would be a pattern for pulling over and letting opposing traffic pass.

Things like that would probably break down at a certain level of crowded-ness, but it did somewhat change my view of regulation in general. I think there are a lot of cases where people will figure things out just fine if you leave them alone and count on them to be responsible, versus having a million detailed rules that are poorly enforced.

He’s not saying it’s Psychology the field. He’s saying replication crisis may be because junior scientist (most often involved in replication) is afraid of retribution: it’s psychological reason for fraud persistence.

I think perhaps blackball is guaranteed. No one likes a snitch. “We’re all just here to do work and get paid. He’s just doing what they make us do”. Scientist is just job. Most people are just “I put thing in tube. Make money by telling government about tube thing. No need to be religious about Science”.

Bubble of protection is 3000 feet laterally and 1000 feet vertically. From the article:

“Unlike traditional Temporary Flight Restrictions, the NOTAM does not provide geographic coordinates, activation times, or public notification when the restriction is in effect near a specific location. Instead, the restricted airspace moves with DHS assets, meaning the no-fly zone can appear wherever ICE or other DHS units operate.”

“In practical terms, a drone operator flying legally in a public area could unknowingly enter restricted airspace if an ICE convoy passes within the protected radius.”

Anyone know the VP who referenced the paper? Doesn't seem to be mentioned. My best guess is Gore.

Living VPs
Joe Biden — VP 2009–2017 (became President in 2021; after that he’s called a former VP and former president)

Not likely the one referenced after 2017 because he became president in 2021, so later citations would likely call him a former president instead of former VP.

Dan Quayle — VP 1989–1993, alive through 2026

Al Gore — VP 1993–2001, alive through 2026

Mike Pence — VP 2017–2021, alive through 2026

Kamala Harris — VP 2021–2025, alive through 2026

J.D. Vance — VP 2025–present (as of 2026)

> mass media fails to call the lies

That can't be all it is: this and other recent, uncontroversially atrocious (when taken out of political context) actions taken by the Trump administration were very widely reported as lies/unconscionable by the vast majority of media outlets large and small.

Hell, we're even only having this discussion because Ars Technica, a publication with ten million readers, did journalism about an event. That's not huge in the grander scheme, but it's not tiny either.

There's certainly many stupid/corrupt things that news media companies should improve. I just don't think "A.P. News isn't calling $thing out" is the problem here.
by terminalshort | 2026-01-25 17:34:37+00:00
My point here is that this problem only seems to be brought up when the research has to do with intelligence. If you talk about genetic differences between "black," "white," or any other racial grouping on any other metric nobody ever brings it up as in my example above. So, while I acknowledge the fundamental weaknesses of the category, I have to conclude that the real objection here isn't the categories, but the topic of the research.

With nary a comment about the intention of the company who is now buying up the land.

>Those that stayed had to go to court to defend their right to live on this abandoned land, all because they wanted to keep the mineral rights to their property. So now, people like Phil assume that the government is just waiting them out. Once they’re gone, putting out the fire will be easy enough. “They’ll take all that red hot coals, but also they’re going to get that rich anthracite coal,” he told us. “And I’m sure they’ll sell that.

This is a useful measure to point the law as a weapon against drone operators who may be recording what’s going on by accident or on purpose. Any drone made in the last few years is going to be emitting its ID, which likely has been registered with the pilot’s name and contact information.

They can then after the fact come down on that person without having to get facial recognition, grab cellphone beacons, or other similar steps.

The paradox of intolerance suggests we should (if all else fails) suppress those whose seek to suppress others.

How is that relevant? Is Lasker seeking to (let alone succeeding at) suppressing voices that disagree with his own?

He might not engage with his critics (e.g. David Bessis) but AFAICT he's not doing anything to suppress them.
