Yeah, a lot of this is just .. well, I hesitate to use the over used phrase "deep state", but a lot of it is the work of people in the security institutions who "advise" the government, rather than the changing cast of the thin democratic bit on the front. There's long been authoritarianism in response to the fear of terrorism, from the IRA onwards. Then there's things like the "spycops" scandal, which make you wonder whether certain protest groups are deliberately engaging in really unpopular stunts in order to facilitate a crackdown.

The British public are in an odd place on this. There's a lot of "folk libertarianism", but that mostly consists of not having ID cards, while at the same time supporting all sorts of crackdowns on protest as soon as it's mildly inconvenient.

And then there's immigration. As in the US, it's a magic bullet for discourse that allows any amount of authoritarianism (or headshots to soccer moms) as long as you promise it will be used against immigrants.

"The researchers identified two main reasons for the uptick. U.S. electricity demand grew at an unusually fast pace, driven in part by an expansion of power-hungry data centers for artificial intelligence. To meet that demand, electric utilities burned about 13 percent more coal last year than they did in 2024.

...

...the researchers said Mr. Trump’s policies would take time to have an effect and they mostly weren’t responsible for last year’s rise in emissions."

If it wasn't for Apple wanting to get rid of GCC due to licensing, and Google as well on Android, LLVM would have remained like Andrew Compiler Toolkit, MSR Phoenix, and similar endevours, another compiler development research project at Illinois university.

Thus what would be the commercial reason to support LLVM's sucessor, especially since the companies that were responsible for LLVM going mainstream, are happy with current C and C++ support, mostly using LLVM for other programming language frontends?

This is going to be hard to fix.

If you use an LLM and agents to regenerate code, a minor change in the "specification" may result in huge changes to the code. Even if it's just due to forcing regeneration. OK, got that.

But there may be no "specification", just an ongoing discussion with an agentic system. "We don't write code any more, we just yell at the agents." Even if the entire sequence of events has been captured, it might not be very useful. It's like having a transcript of a design meeting.

There's a real question as to what the static reference of the design should be. Or what it should look like. This is going to be difficult.

The fine print:

HP recommends Windows 11 Pro for Business. Not all features are available in all editions or versions of Windows. Systems may require upgraded and/or separately purchased hardware, drivers, software or BIOS update to take full advantage of Windows functionality. Windows 11 is automatically updated, which is always enabled. High speed internet and Microsoft account required. ISP fees may apply and additional requirements may apply over time for updates.

Features and software that require a NPU may require software purchase, subscription or enablement by a software or platform provider, and third-party software may have specific configuration or compatibility requirements. Potential NPU inferencing performance varies by use, configuration, and other factors.

Microsoft Copilot requires Windows 11. Some features require an NPU. Timing of feature delivery and availability varies by market and device. Requires Microsoft account to log in. Where Copilot is not available, the Copilot key will lead to the Bing search engine.

HRANA said the unrest had manifested in 186 cities across all of Iran's 31 provinces.

> The Center for Human Rights in Iran (CHRI), which is also based in the U.S., said over the weekend that it had "eyewitness accounts and credible reports indicating that hundreds of protesters have been killed across Iran during the current internet shutdown," accusing the regime of carrying out "a massacre."

> The Iran Human Rights (IHR) organization, based in Norway, said Saturday that it had confirmed at least 192 protesters were killed, but that the number could be over 2,000.

> "Unverified reports indicate that at least several hundreds, and according to some sources, more than 2,000 people may have been killed," IHR said in a statement, adding that according to its estimate, more than 2,600 protesters had been arrested.

(with that said, the US government is likely not impacted and has the intelligence they need for coordinating air strikes, if they elect to proceed with them)

Claude Opus 4.5 can understand images: one thing I've done frequently in Claude Code and have had great success is just showing it an image of weird visual behavior (drag and drop into CC) and it finds the bug near-immediately.

The issue is that Claude Code won't automatically Read images by default as a part of its flow: you have to very explicitly prompt it to do so. I suspect a Skill may be more useful here.

I was hoping for a moment that this meant they had come up with a design that was safe against lethal trifecta / prompt injection attacks, maybe by running everything in a tight sandbox and shutting down any exfiltration vectors that could be used by a malicious prompt attack to steal data.

Sadly they haven't completely solved that yet. Instead their help page at https://support.claude.com/en/articles/13364135-using-cowork... tells users "Avoid granting access to local files with sensitive information, like financial documents" and "Monitor Claude for suspicious actions that may indicate prompt injection".

I don't doubt this is true but would also note that high-profile online outlets --- Ryan Grim's Drop Site News, most notably --- have run pieces talking about how huge anti-government protests are in fact pro-government protests, when that has turned out to be flatly false. (I don't know where they get this stuff).

The Iranian anti-regime movement is very well established and is not the product of foreign intervention. It's actually not all that clear that foreign actors in the region favor regime change!

(I'm not holding out much hope that these protests will actually topple the regime, though it would be amazing if they did.)

We are "just fine" with blurry details, on some level... but a lot of processing a movie holistically comes from that level of detail being present. Even if few people walking out of the theater could put their finger on why the world felt vibrant, it'll come down to the fact those details were there.

So much of movie making is like that. No normal person comes out of a theater saying "wow, the color grading on that movie really helped the drive the main themes along, I particularly appreciated the way it was used to amplify the alienation the main character felt at being betrayed by his life-long friend, and the lighting in that scene really sent that point home". That's all film nerd stuff. But it's the lighting, the color grading, the camera shots, all this subtle stuff that the casual consumer will never cite as their reason for liking or disliking the movie that results in the feelings that were experienced.

They aren't necessary. People still connect with the original Snow White, and while it may have been an absolute technical breakthrough masterstroke for the time, by modern standards it is simple. But used well the details we can muster for a modern production can still go into the general tone of the film; compare the two next to each other while looking for this effect and you may be able to "feel" what I'm talking about.

This is painful. They got a used solder mask holder, a Lumen pick and place machine, a bunch of old Siemens feeders, and a small automatic reflow oven. All these tools needed major work. Everything with firmware needed firmware mods. Everything else needed assembly or major cleaning. Everything needed adjustment. They had to 3D print their own solder paste squeegee. They're six months in and still trying to produce one simple board.

I've been down this road of populating a surface mount board. There is a minimum size for a practical board-stuffing operation, and they are below it. They are using prototype techniques for 100 units or so, not techniques that scale.

Surface mount soldering requires applying hot air in a very controlled way, with the temperature ramping up, holding at the high temp for a few seconds, and then ramping down. On a small scale, you have a programmable oven which tries to do that. Those always have heat distribution problems. For production, you have a tunnel oven, with about six sections at different temperatures and a chain conveyor to take the boards through the tunnel. With the tunnel oven, you let the whole thing warm up and stabilize, and when all zones are at the right temperature, you can repeatably solder boards successfully.

They're using a hobbyist-grade pick and place machine. Slow, but cheap. Plus the software isn't ready for prime time. They looked at a used production machine. Runs Windows XP and wouldn't fit through the door. Rejected that.

They're about EUR 30,000 into this, not counting their own labor. This approach is not going to revive electronics in Europe.

Is there something I'm missing?

> At what proportion? Is it mostly lidar or mostly cameras? Or 50/50?

What proportion of your vision is rods or cones? Depends on the context. You can do without one. But it’s better with both.

> How about when you come 4 way stop. LIDAR is useless as it wouldn't recognize anyones turn signals

Bad example. 99% of a 4-way stop is remembering who moved last, who moves next by custom and who may jump the line. What someone is indicating is, depending on where you are, between mildly helpful and useless.

You can not test that which you do not understand.

Narrow field of view LIDAR units have been moderately priced for years. Forward looking LIDAR is useful for anti-collision systems. It doesn't yield the situational awareness of full coverage needed for full autonomy, but it's good for putting on the brakes.

So, better face his rage then. If those are the options the choice is clear and easy.

Facts matter, as does telling people it is on them to understand them. Otherwise, we will spin in perpetuity refuting people who are not discussing in good faith. I stand by my assertions. I do not believe it is impolite to call out a potential lack of education, or ignoring of facts and reality. Without shared facts and reality, discussion and debate is impossible.

> He thinks he knows better than the experts

It’s a kleptocracy. He doesn’t care. He just wants cheap money from the Fed as patronage.

Lately I've been interesting in biosignals, biofeedback and biosynchronization.

I've been really frustrated with the state of Heart Rate Variability (HRV) research and HRV apps, particularly those that claim to be "biofeedback" but are really just guided breathing exercises by people who seem to have the lights on and nobody home. [1]

I could have spent a lot of time reading the docs to understand the Web Bluetooth API and facing up to the stress that getting anything with Bluetooth working with a PC is super hit and miss so estimating the time I'd expect a high risk of spending hours rebooting my computer and otherwise futzing around to debug connection problems.

Although it's supposedly really easy to do this with the Web Bluetooth API I amazingly couldn't find any examples which made all the more apprehensive that there was some reason it doesn't work. [2]

As it was Junie coded me a simple webapp that pulled R-R intervals from my Polar H10 heart rate monitor in 20 minutes and it worked the first time. And in a few days, I've already got an HRV demo app that is superior to the commercial ones in numerous ways... And I understand how it works 100%.

I wouldn't call it vibe coding because I had my feet on the ground the whole time.

[1] for instance I am used to doing meditation practices with my eyes closed and not holding a 'freakin phone in my hand. why they expect me to look at a phone to pace my breathing when it could talk to be or beep at me is beyond me. for that matter why they try to estimate respiration by looking at my face when they could get if off the accelerometer if i put in on my chest when i am lying down is also beyond me.

[2] let's see, people don't think anything is meaningful if it doesn't involve an app, nobody's gotten a grant to do biofeedback research since 1979 so the last grad student to take a class on the subject is retiring right about now...

It’s a troll account. Go back through its comment history.

They chanted “lock her up” en masse as a campaign slogan. The desire to imprison is quite evident.
