Paediatric anaesthesiologist here.

We mostly use propofol/remifent for maintenance of anaesthesia, and there is (some) reasonable evidence that this leads to less emergence delirium than sevoflurane. We use EEG-like monitors in all paralysed patients over a few months old.

Annoyingly I can’t access the full study, but would be interested to know why the kids in the low sevoflurane use group weren’t moving or coughing with surgical stimulation. The commonly used doses of sevoflurane are used because they are supposed to inhibit movement in response to noxious stimulus. So presumably these patients are all being paralysed or given a lot of opioid to stop them moving?

Using sevoflurane instead of propofol for maintenance if you are trying to reduce PAED is not really standard of care and makes me suspicious they are trying to overstate the effectiveness of their device.

> However, I’m curious about what you mean by “didn’t use the software effectively”.

Specifically, Photos has facial recognition and has had it since iPhoto ‘09. Instead of using this to do the work for them, they manually scrolled through thousands of thumbnails looking for a certain face. When I mentioned I used the facial recognition feature, the others said they didn’t enable it and were fine scrolling for hours.

The software has different tools for different jobs. In this case, the facial recognition was the efficient way to cull down thousands of random photos to something manageable, but they weren’t interested.

Similarly, I constantly use the map view to find pictures from a trip, or that I know were taken around a certain location. People have seen me use it, they’ve asked and I’ve explained it to them, and yet they never seem to commit it to memory to use it for themselves.

I’ve also spoken to people who talked about scrolling through their pictures to delete old screenshots. There is a Utility filter to view just the screenshot. A few minutes looking around the app and it’s right there, but I see people scrolling their whole library.

All of this is not using the software effectively or efficiently.

For what it's worth, I think that sending a message translated to a foreign language you don't master is the worst thing you can do.

You speak English? Write and send your message in English. The receiver can copy-paste it in a translator. This way, they will know that they are not reading the original. So if your translated message sounds inaccurate, offensive or anything like that, they can go back to your original message.

Game jams (similar to hackathons) are great for applying what you already know but with a new group of people. They're much harder if you _dont_ know what your doing (contrary to what you suggest).

I've found that the group really makes the experience, and find them less fun for the tech and more fun for learning about the people through the work and a team project without the constraints of a corporation.

And generally, it's not just people who aren't tied up in this that will participate, but people who will make time to do something exciting and form an interesting connection.

I wasn't talking about the meaning of democracy but its practical implementation. In practice, all systems of governance are built upon institutions.

> Policy in a complex system like society is infinitely debatable and no amount of education will ever find a "right" or optimal answer to the hard questions a society faces.

You are right on the first part, which is why voters need to understand policy that affect them and vote for the people they want. I didn't mention anything about the policy or their vote being correct, just that they should understand it when voting.

> Division and partisanship is guaranteed in a democracy that allows free debate and expression, regardless of the level of education among the people.

The purpose of education is not to avoid those things you mentioned but so that debates and disagreements happen between well informed voters, not deceived voters that vote and disagree based on vibes and manipulation by malicious forces and deceptive demagogues. More debates and disagreements between actual well informed voters is a sign of a very healthy democracy. Hatred, treason and violence are not.

> Therefore something else must sustain the people as a community and bind them together.

Yeah, actually liking their country and educating themselves enough about the policy and choices being made on their behalf, that's what. Education here doesn't mean a phd in chemistry, it means reading,writing, critical thinking skills and being able to consume news and information and discerning facts from fiction.

> * perhaps LLMs can build such a theory from existing codebases, or will be able to in the future

If the source code is a lossy representation of the theory, doesn't that answer this question with a conclusive "No"? (If there is anything -- LLM or not -- that can do this, then the source code is not lossy after all.)

EDIT: Clarify last sentence.

Their essay on composite infantry types is interesting as a Crusader Kings II player, because the game has tons of historically accurate mixed units you can recruit that combine archers and heavy infantry/pikes, but virtually all of those units suck because the combat mechanics still enforce a rock-paper-scissors dynamic.

https://acoup.blog/2022/04/01/collection-total-wars-missing-...

Specifically, every 15 days, your army rolls a "combat tactic" (based on number of troops) that buffs certain types of units and nerfs others. "Advance" buffs heavy infantry, "force back" buffs pikemen, and "charge" buffs cavalry. Then if an army uses "advance" goes up against "force back", they get an additional boost. Likewise, for "force back" against "charge" or "charge" against "advance". There are also archer-specific tactics that don't play a role in this triad.

The simplified combat tactics to enable rock paper scissors matching is what makes the historically accurate archers + pikemen trash. No matter what combat tactic I roll, I would rather have either additional archers or additional pikemen because only one gets boosted at any given time. The game does not model the mutually reinforcing nature of diverse armies because it could break the rock-paper-scissors triad that says certain troops should defeat other kinds of troops.

In fact, having a diverse army is penalized because you will "roll bad tactics". If I used China's 250 archer : 100 pikemen retinue, they will correctly alternate between pike (the force back tactic) and shot (barrage tactic), then get slaughtered by another army that had 250 pikemen : 50 archers because their 250 pikemen was getting buffed 24/7 by force back instead of having to share the limelight with my archers.

That's nice, but A it's meaning is disputed as evidenced even in this thread and B I doubt it's applicable to current circumstances. Outside of those two concerns I have, generalities aren't usually that accurate and typically fall flat.

Again if you have something stronger that's cool. I don't run my life on star trek or a christmas carol either.

Edit: FWIW I’m not against frameworks, I just think ones built on reason, empirical evidence, and moral intuition tested against reality beat ones that rely on ancient metaphor and selective reinterpretation. If the goal is clarity, integrity and useful signposts for modern times, that’s a better starting point.

> Distressingly, the people most passionate about AI often express a not-so-subtle disdain for humanity.

I have noticed something similar: those who are ultra-passionate about AI are often Extremely Online, and it seems like their values tilt too far away from humanity for my taste. The use of AI is treated almost as an end in and of itself, which perpetuates a maximalist AI vision. This is also probably why they give off this weird vibe of having their personality outsourced.

Six is a not-uncommon number of parties qualified for ballot access in a US state, though some have fewer and some have more.

Another take on this: https://zbang.vercel.app/

- Search bangs redirect the search to a specific search engine

- For example: `!ddg search term` or `search term !ddg` searches for `search term` using DuckDuckGo

- As a bonus, the input is more ergonomic for mobile and/or multiline input.

- Insert `!` via double-space

- Auto-growing multi-line input with fullscreen mode; RETURN is a newline, by default.

- (SHIFT-RETURN, or "double-keypress RETURN" submits form.)

- Auto-complete bang triggers with "double-keypress" of QQ, WW, EE, etc

> Much of Koskinas and his team’s efforts stem from Vanguard having the deepest level of access to a gamer’s computer

Why would you trust anyone to do that? It's malware style access. Client side anti-cheats that need kernel level access are unacceptable, that's why I'd never play any games with such garbage.

Instead of this, let these companies focus on server side anti-cheats that detect behaviors that can be defined as cheating. Shouldn't AI be good for these kind of tasks? But of course it's cheaper for them to slap malware on user computers and call it a day.

I've tolerated AI autocomplete in VSCode but I am a bee's dick away from turning it off, because it so often generates a huge chunk of code that is ALMOST correct, and determining where it is wrong is as much a chore as writing it would have been. But, it's like I've got a junior-coder sidekick who doesn't take any feedback. Not great.

Question regarding two apparently conflicting bits of information:

- A: Fillet edges in the filament direction - B: Have a sharp edge for the seam.

How would you crack that nut, as A prevents B. For example, on a rectangular box, maybe fillet 3/4 of the corners, and leave the 4th sharp?

>> I imagine it would be next to impossible to fight the instinct to try and hunker down behind some cover.

Which is why formations were used. The inexperienced men were placed in the center, hemmed in by more experience soldiers who were less likely to run for cover. Sun Tzu would call this a death zone. A soldier will fight when to fight is his only option.

This is a fantastic article. It neatly summarizes several tricks that took me years to pick up.

Another useful trick to minimizing material in a print is to not print surfaces at all. Most of the mass in a print is concentrated in the shell. If the top and bottom surfaces are not particularly critical to the function of the part, then you can remove either surface. The slicer can still fill in the volume enclosed by these surfaces with infill. If you use a planar infill, such as a rectilinear, hexagonal, or triangular infill, the parts can look quite nice. This trick works particularly well on mostly flat parts.

I use two TPU parts printed in this manner daily: A phone case [0] and a relief strap for a pair of headphones [1].

> Doing or learning “It” in 2025 means using AI whether to understand it better or use it to get better grades.

Depends, I think. If we are talking about writing an essay (and I believe we are), then the LLM is somewhere between useless and counter-productive.

Of course, if the LLM is used to understand an RFC (I would debate how useful it is for that, but that's another discussion), then it's different. The goal was to understand the RFC, it doesn't really matter how you did it. But the goal of writing an essay is not to end up with a written essay at all. Nobody cares about it, you can burn it right after it's graded.

Tech companies, at least those who weren't founded on AI, have a significant number of people internally who have exactly the opinions in this blog post.

Outside of the tech ecosystem, most people I encounter either don't care about AI, or are vaguely positive (and using it to write emails/etc). There are exceptions, writers and artists for example, but they're in the minority. To be clear, I'm also not seeing "normal" people raving about it much either, but most people really do not share the opinion of this post.

I realise it may not seem like it, but most big tech companies are not designing for high earning valley software engineers because they are not a big market. They're designing for the world, and the world hasn't made its mind up about AI yet.

The early USA gave rise to a party known as the Democratic-Republicans which had the critical mass of officials and candidates to rival the Federalists and eventually dominate them so badly that by 1824 no opposing party even had a candidate for President. There were actually 4 candidates on the ballot though, but they were all from the same Democratic-Republican party. In that case none had enough electoral votes, so Jackson won that one when it was decided by the House. He had a total nationwide popular vote of 151,271, so you have to figure that each vote had so much of a stronger voice back then under a system quite similar to today. Unless you were there I don't think the difference in scale would be easy to fully comprehend. The party was supposedly doing well in lesser races across the growing US too.

https://en.wikipedia.org/wiki/List_of_Democratic-Republican_...

Then apparently the party just kind of split up and re-organized into the "two-party" system that has continued to dominate ever since.

There was no threat until decades later when the Free Silver parties arose based strongly on reversing the trend where increasing economic opportunity was being systematically pushed further beyond reach of average citizens, in the face of bonanza precious metal discoveries that would have been able to pull the whole population ahead of Europe decades sooner if the Free Silvers would have had their way. Bipartisan effort was resurrected as if from a single party again, and the third party was crushed by a well-maintained machine which was bigger than either one of the major parties on their own. Before the citizens could be allowed to get a little taste, the Silvers were assimilated by the Democrats in a platform expansion that was over-dramatized but badly diluted their objectives. It does seem to be the first real big platform deviation between the Democrats & Republicans to start off the 20th century with, but the Silver supporters continued to be systematically disadvantaged for decades to come.

No third party movement has presented that level of threat to include such economic clout, but if so, deeply rooted underhanded countermeasures would be deployed, it would apparently take more than anyone could imagine, so no third party for you.

same as hardware hacking on "conferences" - they make you go with them on 2 hour journey of unlocking something, just for you to realize after doing some of it by yourself, that they can just download firmware update from manufacturer and run BINWALK utility on it, it will spit out filesystems, which you just mount, and read from that how is everything configured, how things work, what version of linux kernel they use.... so it is just hacking of YOU. it is advertisement, marketing story.

This looks so good. I’ve gotten into 3D printing in the past six months with an A1 Mini. I initially bought it intending solely to do creative projects with my kid, but I’ve been surprised to find myself getting deeper into printing functional parts. I recently printed a 6” server rack for a GLi.net Beryl and Apple TV for travel, from a combination of pre-designed and self-designed parts.

3D printing as a pursuit can be time-consuming - there’s always a risk with these things that you take them on as a dilettante and they end up gathering dust in a corner. I initially scraped by with some middling Blender skills (leaning into non-destructive operations where possible), but that is far from ideal - you really do need CAD. But to anyone considering jumping in, I would say: if you get an A1 (get the full size, not the Mini) and use Claude to write your parametric OpenSCAD scripts, the time commitment is such that you can _just about_ indulge in this hobby as a dilettante - eg, as a project for your kids. Without LLMs, I think it would be too much of a commitment unless you’re really dedicated, or already have CAD skills.

Anyway, gonna go read this in full.

Historical reasons, United States has always been uncomfortable with Democracy despite all our cheerleading around it. US Founders had a fear of populist sentiment leading to "rash" decisions and thus United States system has always been setup as bulwark against it. Entire Senate elections and rules serve as bulwark. Electoral College is another bulwark. Constitution Amendment process another bulwark. Our acceptance of leaving many issues up to the court like Abortion, Gay Marriage and Immigration. List goes on and on.

10 free redactions per month? 10 per day seems like a much more reasonable low amount. Why is there even a limit on number of uses for local compute? Why is it impossible to see the price? I'm glad this works for you, but it seems like you tried jumping straight to the "enshititication" stage of proprietary software before luring users in.

For everyone pointing out that this idea can be cheated by just typing AI-generated text into the editor - add an AI-detector to the editor. Gamify the whole thing by making a leaderboard of people with the lowest AI-detector-similarity score across things that they have "written"

In a class setting, maybe make the AI-detection an element of take-home assignments - whoever gets the lowest AI-similarity score gets a few points of extra credit or something

As for computer science courses, I'm guessing it's hard to not write simple code that appears AI-generated...so maybe that kind of work needs a written summary to go along with the code as well

> The quote does say that Altium does it out of the box though?

Sure, if you're routing 8+ layer boards with blind vias and PCIx16 and DDR5 buses every day, go buy an Allegro or Expedition licence for 6 figures. It's absolutely worth the money.

For Altium, I find that the "showstopper bug that Altium has":"feature that Kicad doesn't have" ratio is almost always strongly in favor of Kicad.
Ask HN: How to remove space switch delay on macOS?
by kulikalov | 2025-05-04 23:57:20+00:00
On macOS, when you switch between Spaces or move to a fullscreen app using gestures or Mission Control, there’s a delay where:

- The new Space or fullscreen app visually appears on screen

- But keyboard or input focus hasn’t yet fully shifted — meaning you can’t immediately start typing or issuing shortcuts to the app

I already reduced the motion in settings to the minimum and switched to fade instead of sliding animation.

I know that people solve it with yabai, but I'm hesitant to spend a day figuring implications of disabling SIP to use yabai. Is there any way to just remove the delay and make transitions instantaneous?

Dual-booting utterly sucks experience-wise, and the very second you allow any kind of "untrusted" code on a device - even if it's another OS nominally "separate" from the main OS - you multiply the attack vectors that are possible.

That's part of the reason why Apple is so against not just jailbreaks for mobile devices but also any kind of non-Apple-sanctioned access to anything they deem safety critical.

> I wouldn’t be so sure about that. They would definitely mention their command over a cavalry charge (usually fellow nobles or knights depending on time period and polity) but archers were generally lower status, even though they were better trained than some farmer-soldier from a distant retinue.

But we do have so much written about musket volleys, and those were done by lower status soldiers as well. It is very strange that much was written about musket volleys but not archer volleys.

This is a pet peeve. Everyone has learned this meme that “economics is dumb”, and now people assume that the most basic difficulties they can imagine are probably valid criticisms. Modern economics has limitations, but they’re not so simplistic and obvious as the ones you’re raising.

The problem isn’t that magical market theory takes an average and determines we’re all better off because we all got poorer and one guy got way richer. But it might say that we’re all better off if everybody DID get richer, but one guy got _extra_ rich. That we still might object to the latter situation is a valid concern, but it’s a very different level of oversight on the part of the economist.

Another one that comes up is that people seem to think that because the consumer is assumed to be ‘rational’, this implies that the economist is imagining people as unfeeling automatons incapable of valuing experiences over material wealth. When really it’s more like “if I offer you two paid vacation options for the same price, you will choose the one you prefer”. Even that, it turns out, is inaccurate and incomplete - but it’s a much more defensible simplification.

> And they also have a parliament, as does the USA.

A "parliamentary system" is not about just having a parliament (an elected legislature), it is a name for a system where the elected parliament is the paramount power in government, including choosing the head of government. The French have something close to that, the US does not.

The French have a semi-presidential system where, as in a parliamentary system, the head of government is the PM elected by the parliament and formally appointed by the President who is the head of state, the US has a (very strong) Presidential system, where the President is head of government (as well as having a Presidential election system that, even ignoring the role of the President, inherently favors duopoly more than the two-round French system.)
