I studied at Berkeley and Princeton (big classes vs small classes), I find your view to be fundamentally flawed. You presuppose that meritocracy is an inherently fair value system implementation, while many critics and philosophers reject this assumption; in the next breath you delegitimize social justice issues subtly framed as "identity politics", needless to say many other critics and philosophers do not share this talking point either.

Essentially, Oxford researchers—institutionalists—are on the worst perch to evaluate institutions because they don't have a deep understanding of cross-societal differences and inevitably end up using their position to ad hominem and rationalize their own insider-ish biases. That's a tough ideological shell to crack through if the goal is to maintain an objective discussion.

As to the matter, the real issue is that Oxford/Cambridge is a different system than the US big universities. The people who apply to Oxbridge are from UK-related nations where they can study for an IB or an A levels. So for example the miscomparison that "A levels are harder than SAT/AP" is because it fundamentally misunderstands the historical aims of American education philosophy and very different social formations of the 20th century. This is a better approach to explain why UK/European universities are the way they are versus the (previously) leading ring of STEM universities in the US.

Take as another example the PhD system. The American system is different, they prefer non-Masters students direct from undergrad. The European PhD is only 3 years! By one metric that sounds insanely short and not enough time to develop a PhD-level mind. By another metric, yet another systemic difference, with differing rationales and intentions.

More deeply, if we really are to reject identity politics, then a class-based critique would demolish the notion of university education as a filtration system for all societies. Second if Oxbridge are so good then why is all the world's research still essentially American with some satellite results coming out of Europe and perhaps (very cautiously) China? A response that decouples education from research is itself an assumption, one that the American academic philosophy in practice does not agree with. American academia prioritizes research, then teaching, then community service. In other words, decoupling “education” from “research” is itself a pedagogical-philosophy assumption, one the American/British/European academic systems nevertheless still has various problematizable, elitist mindsets about.

So there's a much broader social, political, and historical/class analysis to be made rather than this kind of wonkism of foolish comparisons, and I'm rather miffed that supposedly world-class researchers are still not cognizant of this. Sometimes we are too close to critically think about our own habitus fairly.

Or, before making graphs and charts, read some Paulo Freire.

Looks like spot melt laser powder bed fusion (L-PBF). Electron beam doesn’t make sense for something on a smaller scale like this; it wouldn't have the resolution. Spot melt is interesting. Renishaw is the only manufacturer I’m aware of that uses a pulsed laser vs continuous wave (and I’m not even sure if they’re still doing that for their newer machines). I would’ve guessed it would’ve been printed on a Farsoon since it’s in China. I just wish the images had scale bars to give a little more info.

Thanks for all the work finding the local national reporting on those statistics.

Turkey's numbers look crazy though. Almost doubling every year? Is that just the exchange ratio's runaway hyperinflation? https://tradingeconomics.com/turkey/currency Almost linearly upward for the last half decade.

Thanks for the tips! It's really interesting going back to that point of indistinction in these languages where even the proximity to old English is so strong. I've been hoping to try and read some of the old sagas in the process, but that's probably a bit too far back -- I'll have to see if there are some good century old translations thereof, as you suggest.

The phonetics, on the other hand, are presenting some challenges...

Not bad. Some suggestions: - make it behave more like the original Launchpad (e.g. click on empty space makes it disappear) - make number of columns adjustable - make font and icon size adjustable - I should be able to go back from a folder with a swipe or the back mouse button - I should be able to select multiple shortcuts (e.g. by holding CMD) and move them to a folder

But, this is already better than what Apple gave us as a replacement for Launchpad, thanks! Will you add it to Homebrew?

We might just have to agree to disagree. I believe that an experienced developer brings instincts and stacked skills even to domains where they have never touched.

In other words, I don't think that you temporarily regress to "junior" just because you're working on something new. You still have a profound fundamental understanding of how technology works and what to expect in different situations.

This reminds me of the classic "what happens when you type google.com into a web browser" question, with its nearly infinite layers of abstraction from keyboard switches to rendering a document with calls to a display driver and photons hitting your visual receptors.

We might just be quibbling over terminology, however.

It is being used as a wedge issue by conservatives in the US, but I feel that liberal politicians made a rod for their own backs on this one. An unforced error that their opponents were happy to take advantage of.

This article has an interesting viewpoint, from the perspective of a feminist liberal who had been trying to warn Democrats about this for years: https://digitalcommons.uri.edu/dignity/vol10/iss2/8/

I agree this does not make sense for you and me, but it makes sense for the corpo bean counters that don't understand how this works and they were told AI makes people better, so they need less people and less skilled people. It is not hard to get to the wrong conclusions based on the AI marketing materials.

I see the discussions around AI in my company (big, not IT but with several large IT departments) and even our MBA IT leaders believe all the buzzwords to the letter.

I'm confident you're a better judge of the worth of A-levels than the people who've never even taken them furiously insisting they're objective indicators of merit, and not high school syllabus-recollection/essay-writing tests which are easily taught to, actively fudged by some schools and greatly variable in actual difficulty from one subject and exam board to another.

Still, your grades (and mine) pale in comparison to all these youngsters with an opportunity to get A* grades...

>According to this post, technological stagnation via regulation is what leads to zero-sum, totalitarian societies (in Thiel’s worldview).

What is the incentive of someone who thinks has a shot at having control over such powerful technology? They will do and say anything that is necessary to justify doing it.

My argument is simpler, if "we" don't do it "they" will do it. It's something we'll have to wing. It is surely happening. The real problem will come from the people having control over such tech, since the tech breaks an old game, as old as humans existed and started forming groups.

And I see no billionaire who wants to develop and take control over this tech, explain how they'll fix the problem it creates, at game level. I do not care about promises, they mean nothing. I only care about game strategy that guarantees most humans stay alive in such an environment, with age old game rules breaking down.

If you want to quadruple your amp hours without modifying the hardware, just treat 25% of the voltage gradient of each battery as your unit of measurement.

Alternatively, since this is USB-C, and we assume the marketing copy is honest, use the max voltage USB-C can deliver: 20v.

So, draw 20V from this device and measure the amp hours it outputs.

Wh is really the only sane way to go.

His zero sum politics is not different than America’s zero sum politics at all. The consequences of these are well studied, and it can be predicted what will happen, and it could be predicted since at least 2014, even before Trump. It’s not rocket science. It was obvious even back then that the positive sum game in politics is dead long term, and that means and always meant destability, not just politically, but also economically, and wars. Netanyahu is just a few steps ahead of Trump. Trump will also start a war the moment when it grants him more power, for example. If we are lucky not some stupid one. I hope that he won’t in the next few years, my prediction in 2014, ie large war in 25 years, would come too early. We were on track until early this year. He, for “some” reasons, wants it earlier.

In case of Netanyahu, if somebody can stop him, without following illiberal democracy (alt-right, fascism, far right, whatever you want, the same), that would mean that in long term even in America it would be ended. If people starts to realise en masse what’s happening for example, alas a very improbable one. There is higher chance there, because they are in front of America in this sense.

Nothing, and absolutely nothing indicates so far, that this deterioration will be stopped. And when the keg will blow, you cannot predict what happens after that. That’s how it matters.

But honestly, why would you activate the "hype" category? I can go to my local community college if I want to hear people say "my AI is alive" or "you should always optimize locally."

That being said... CMU always had a decent program (as did UIUC.) They came down in my estimation when they started granting trade school degrees. In the old days, you had to take a class on parsing and foundations of computing to graduate. You could talk to a grad who knew what a recursive descent parser was and what it's drawbacks were. And there's a chance they could understand the basics of Turing's paper(s).

There's a maxim I read somewhere that undergrad was supposed to change the way you thought more than teaching you facts (and maybe skills.) What I liked about the old system is you were taught a concept (functional decomposition, for instance) and then concrete examples were given to support the concepts. Now it seems like students are taught where to download python packages and enough unix commands to type in example code from online forums.

CS pedagogy in the states is a joke, but I guess if I want someone to write a PHP plugin for wordpress, I know where to go.

Hmmmm. I can attest to qemu com ports working for my hobby OS, which does work on hardware com ports as well. For qemu, I use the com port as the primary console. But, I just assume there's a comport at 0x3f8, I don't do detection.

I don't remember if I got virtualbox com ports to work, I had a lot of trouble with virtualbox and decided it wasn't on my support list.

This is output only, but if you don't have a better way to test if qemu comport works, you can run my kernel with

wget https://crazierl.org/crazierl.elf qemu-system-i386 -display none -serial mon:stdio -kernel crazierl.elf

You should get a bunch of useless debug output, but it came through the com1. If that's helpful, the relevant code is more or less here https://github.com/russor/crazierl/blob/4e41bfa5c5bbae078a57... (init starts here, writing characters a smidge later on line 324)

It’s the harmless version of “my tribe battles your tribe” for thousands of years, without the bloodshed. We’ve evolved to enjoy competition in general.

Not everyone of course. But I find sports fans to be not that different from chess fans for example, in their passion, armchair strategy, and sheer emotional ups and downs.

My personal favorite sport is Formula 1. It tickles all the same parts of our sports fans brains, but also tickles my nerd brain with the strategy, lap math, and all the precision and tech (apart from the fact that I personally looooove driving and Kart racing)

About the tech, you’d be amazed at the amount of tech involved in F1. Just the bandwidth used for telemetry. The supercomputer simulations performed during races, etc. and that’s just the computer tech.

Presumably not what Israel is doing now. I do fully agree with destroying Hamas. How is the current situation going to achieve that?

Either they will have to eliminate the entire population of Gaza one way or the other (I can’t see any country that would be willing to accept all those people..) or as soon as they leave Hamas will get thousands and thousands of new recruits, due to obvious reasons. There is no better way to radicalize someone than blowing up their house and murdering their family..

But in large part the main goal of what is happening now is the preservation of Netanyahu’s political career (and that of his cronies). Just like when he was supporting Hamas to divide the Palestinians.

That's the problem -- except in the rare type of org that thinks past quarterly or annual results and thus values training up a pipeline to be the future seniors -- economically speaking, all the junior devs should be fired, and the simple tasks they can do are the same set of tasks that can be accomplished by a senior at the helm of AI at 10-50x the speed.

This can go both ways though. I've had instances where after a long somewhat tedious back and forth with Claude Code what I'm looking for finally "clicks" and it starts one-shotting requests left and right. But then after coming up to the end of the context window, I compact or ask it to update CLAUDE.md with what it learned and it loses the nuanced understanding it built up through trial and error and starts screwing up in the exact same ways again with fresh context.

And then I waste 20 minutes bashing my head against the wall trying to write three paragraphs meticulously documenting all the key gotchas and lessons from the "good" context window with the magic combination of words needed to get Claude back in the right head space to one-shot again.

At least if I pull that off I can usually ask Claude to use it as documentation for the project CLAUDE.md with a pretty good success rate. But man it leaves a bad taste in my mouth and makes me question whether I'm actually saving time or well into sunk cost territory...

Fourth power of the distance, actually. That's the radar equation. You have inverse-square losses going out, as the beam expands with distance. Then you have inverse-square losses coming back when the target is much smaller than the beam. That's the problem flash LIDARs face. It can be overcome with enough laser power out to 20-30 meters.

That's where the beam diameter at the target is much larger than the target, as for aircraft. With a small scanning dot from a LIDAR and a nice big target like a car, almost all the power hits the target, but you still have inverse square losses coming back.

Meet a tool I built called insteinAI, InsteinAI is an AI Navigation and Task Assistant that lets businesses add AI-powered actions to their websites. Built using computer use models from Anthropic and OpenAI Operator, our solution means customers no longer have to worry about navigating, finding features, or getting stuck—the agent understands the website and acts for them.

For businesses, this translates to customers having an intelligent agent that retrieves real-time data and takes actions on their behalf, significantly enhancing the customer experience.

Also, our current technological regime, sponsored by Peter Thiel, is what has given rise to totalitarianism today. Propaganda, anti-intellectualism, flooding the public space with disinformation, promotion of extremist viewpoints under the guise of common knowledge—all made possible by our tech oligarchy… and streamed directly into the eyeballs of the unsuspecting world population. We in the tech industry are complicit actors, but Peter Thiel and his ilk are modern villains.

If we hadn't bombed these cities we might not have won the war. Arguably we didn't have to nuke Japan but chose to over the cost of the lives of our own soldiers (including my grandfather a marine in the pacific). War involves doing horrific things you don't want to do and wouldn't normally do (look at Israel's actions pre Oct 7th versus post, this sort of war is not the natural state for Israel). War requires you lean on the side of doing too much damage versus limiting your military actions. War requires you take maximal actions, unlike policing where we try to use minimal. If the US fought Japan how people want Israel to fight the government of Gaza, I would not exist, my grandfather would have died storming Japan. It would have been a more moral victory, but it is very hard for any society to choose sacrificing their 18 years olds in a conflict initiated by the other side, when war strategy dictates that other paths/actions be taken, paths with less of your 18 year olds dead and a higher chance of reaching your goals. War by it's naturing is fought maximally, not as a police action.

This is also not a gentleman's war. A neighboring government supported by their citizens who joined in spontaneously, launched a surprise attack that killed 1000+, and indiscriminately maimed/raped/tortured thousands more, while broadcasting video of themselves kidnapping random 6 year old girls to the world, neighboring citizens who phoned home to their parents to brag 'I killed 10 jews today'.

War sucks. War is horrific. Which is why it sucks Hamas, the government of Gaza, chose this war. Why it sucks Hamas structured things for the war to proceed, with maximal civilian damage and casualties. Why it sucks Hamas chose to use civilian hostages abducted during the murder/rape/maiming of thousands. No country can just let their citizens be abducted and held captive like Hamas choses to do, intentionally ratcheting up the pressure/tempo of the war that they initiated.

One major problem with Ted's design is that it wasn't simple enough to support multiple compatible implementations.

I'll repeat the James Clark quote from the wonderful DDJ interview that I posted to the other discussion about Ted Nelson:

There's a wonderful DDJ interview with James Clark called "A Triumph of Simplicity: James Clark on Markup Languages and XML" where he explains how a standard has failed if everyone just uses the reference implementation, because the point of a standard is to be crisp and simple enough that many different implementations can interoperate perfectly.

A Triumph of Simplicity: James Clark on Markup Languages and XML:

Google Summer of Code is bad. I don't want a trillion dollar monopoly influencing FOSS.

Sponsoring the Linux Foundation can be bad, depending on who does it. Individual people with their donations?

Releasing libraries as Open Source is not bad. But if you release them as a corporate behemoth, who employs the people who work of them, and have them assign copyright claims for their contribitions to your corporate entity, it is worse than a community drive FOSS project.

I had the idea to do medical animations in a very lo-fi style a while ago (plasticine, cardboard and yarn, that kind of thing), around the time when Don't Hug me I'm Scared first came out. I felt it could add a charming contrast to the usually sterile and dull 3d visualisations. Everyone I pitched it to was excited until it came time to secure funding, at which point the idea was dropped like a hot potato.

The academic institutions all felt that students from overseas wouldn't have the same cultural touchstones, and would feel the lo-fi material cheapened their hugely expensive course!

I applied to MIT from the UK 15 years ago, I'm fairly sure I'm not among whom you mean by 'the wealthy'. (I failed the alumnus interview; failed STEP mathematics exam to meet accepted Cambridge offer; went to Imperial.)

Not to say I'm (nor was) 'the very top' either - I just liked the idea of MIT for the same reason Imperial appealed I suppose.

It's a thinking challenge, not an AI challenge.

A while back, a junior asked me a question. They wanted to do X, they had code, with error Y. So they searched for it, got a page on Stack Overflow, pasted "the answer", then got a new and different error.

They:

- didn't understand the original code

- didn't understand the original error

This is fine. They then searched for the error and found a relevant page.

This is also fine. However, they:

- cut-pasted "an answer" from SO _without understanding if it was relevant or not_

The junior was hoping to work with a Puzzle: adding information will gradually give them a solution. In practice they are working with a Mystery: more information makes the task harder since they can't distinguish between different aspects.

I focused them on a few relevant details and let them go to it.

They're about the same as before, they weren't terribly large to begin with though. From what I've seen the region crossing issues aren't caused by script state serialization, but hard to track down issues in edge cases in object handoff that're outside the scope of my contract.

Very reasonable other side to this story, which doesn’t come as much of a surprise. Too bad it didn’t hit the front page.

People went WAY too far WAY too fast on this. There HAS to be urgency to this, the software supply chain is presently, undeniably, under attack.

Frankly, everyone blasting RubyCentral the last few days should feel shame and embarrassment. These aren’t evil suits at Microsoft, they’re normal people invested in maintaining a critical piece of infrastructure for the good of all who love and profit from Ruby.
