There's no way to make these safe - it's almost comical and this could be an April 1st joke.

Case 1) how are you handling potential rapid TCAS climbs/decent? You're making the targets a lot larger and less responsive. If TCAS commands a decent and slow down, you will be overtaken by the tow.

Case 2) landings thay require rapid braking, such as short runways for emergencies or engine fires (rapid brakes used so emergency vehicles don't have to chase 2km to get to you)

Case 3) aborted take offs. Brakes will need to be more performant and reactive than the ones we have on the main aircraft

Case 4) taxiing across active runways now has reduced margins.

Case 5) go-around performance is diminished. Already sometimes tight margins on that, what happens if you need to do a go around but the landing gear on the glider collapsed and is now a ground anchor?

The problem comes in when the complexity is both not optional and not rational.

Hooks do not work as real functions. They are magic. Why are they magic? I don't know, they certainly don't need to be. What state do they change? I don't know. Why do they look pure but actually mutate the application states? I don't know.

Why is react not reactive? Why is it if I change state the entire website rerenders? I don't know. React has a virtual dom. It knows when I change state because I have to tell it, manually. And then... It doesn't use those.

But it's okay, because you can `useMemo`. Why do I have to do that? I don't know.

Evidently I don't have to do that, because react has a compiler that does it automatically now. Why can't react just do it? I don't know. Clearly it's possible. And also every other framework does it.

> But there's probably also people like me who just dropped 2k on a new system to self host my own to customise the pipeline, and integrate it into my house without sending data offsite

There's dozens of us I tell you! We're entirely irrelevant in this story. The only thing that would change this is if Apple at some point makes it turnkey to run good models on their hardware. That's it.

> ... memory and cpu performance have improved at completely different rates.

This is overly simplified. To a first approximation, bandwidth has kept track with CPU performance, and main memory latency is basically unchanged. My 1985 Amiga had 125ns main-memory latency, though the processor itself saw 250ns latency - current main memory latencies are in the 50-100ns range. Caches are what 'fix' this discrepancy.

You would need to clarify how manual memory management relates to this... (cache placement/control? copying GCs causing caching issues? something else?)

My pet philosophy is that math is real because the objects have persistent effects, like with the "if a tree falls in the forest..." riddle. Something that isn't real would be a story, because things do not have effects in it.

If a function is one-to-one, it has a (right? left? keep forgetting which one)-inverse. But if Moshe the imaginary forgot the milk, his wife may or may not shout at him, whichever way the story teller decides to take the story... So a function being one-to-one is real, but Moshe the imaginary forgetting the milk isn't.

I like this view when I'm being befuddled by a result, especially some ad absurdum argument. I tell myself: this thing is true, so if it wasn't we'd just need to look hard enough to find somewhere where two effects clash.

I've already seen LLMs suggest products using Reddit comments as a reference, and when I investigated the Reddit comment it was by a blatant astroturfing account (nearly every comment for the same product) that probably bought upvotes to get their comment to the top of the thread. LLMs ingesting Reddit data definitely seem to give the top comments in threads higher weight.

Interesting. As a vim fan I think I would be very unhappy with any layout that didn’t have hjkl as my home position. But, of course, the ability to experiment is a huge strength of open source projects.

What a cool project. I grew up playing with modeling clay, but never did anything with those skills. It is fascinating to see them used in something useful like this.

Maybe a scanner of some sort is needed, to share 3D printable versions of clay objects, haha.

What Intel does not seem to understand, at least from the quotes in that article, is that you are also doing open source for your customers.

Doing open source makes it easy to get customers to use your products. You could also hide them behind NDAs or licenses and make it hard to become a customer. But of course that never makes it on to a balance sheet, which makes open source expenses seem like a pure loss to the management.

I get they don't care about me as an individual, but companies tend to be 'lawful evil' -- if something is in their best interest (like a user returning to a site they boycotted for many ears to add eyeballs to ads), it's confusing and annoying when they don't seem to follow their own incentive structure.

Anyways, it's with their legal dept now so I'll try to put the blue site out of my mind and enjoy better venues like the orange site :-)

< 20 lines is nice.

Just refreshed my memory by looking at mine. 103 lines. Just the glance brought back painful memories. The worst areas were:

- Installing ruby/bundler/gems/postgres/js libraries, dealing with versioning issues, and every few months have them suddenly stop working for some reason that had to be addressed in order to deploy.

- Installing capybara and headless chrome and running system tests (system tests can be flakey enough locally, let alone remotely).

- Minor issue of me developing on a mac, deploying to heroku, so linux on GHA needs a few more things installed than I'm used to, creating more work (not the end of the world, and good to learn, but slow when it's done via a yaml file that has to be committed and run for a few minutes just to see the error).

I don't see how this is clear backtracking. Trump made the comment but only one agency (that I'm aware of) mentioned back pay in the information all federal workers received.

The article also states "...the Office of Management and Budget has deleted from its guidance any reference to the 2019 law [requiring back pay after shutdowns] back pay for furloughed federal workers"

OMB also issued a press release stating the law only applies to the one shutdown the law was created after.

So

1. Trump hasn't backtracked himself.

2. OMB has stated an argument allowing them to challenge the 2019 law.

4. The IRS is just one agency and Trump's comment was clear that only those he believed deserve back pay will get it. There's no contradiction in what the IRS said.

Also, A long drawn out executive power court battle will take months to years. People won't be paid unless there is some emergency relief from the courts.

I've heard the colloquial phrase "type 3 diabetes" appear a lot in talk about Alzheimers, so I'd be shocked if there isn't a lot of research going into that. I just read a book about how metabolism is related to a lot of mental disorders (depression, schizophrenia, etc.) so I think it's something that's definitely being looked at (the book is called Brain Energy, I think).

There's going to be encryption either way in any modern protocol, and then the header manipulation stuff is already all done in hardware. It's probably more efficient in UDP than as a direct IP protocol, because UDP is fast-pathed in ways protocols other than 6 and 17 aren't.

Having a diversity of IP protocols isn't a nice thing. The designers of TCP/IP made a protocol specifically for doing the thing you wanted to see SCTP do: it was called UDP.

I think Meteor is finally starting to fully overcome the tech debt from the second half of the last decade. They're in a recent Node.js release, and the next version will integrate a modern bundler (Rspack) in its tooling.

Lots of apps are still stuck in Meteor 2.x hell because of the dependency on Fibers though.

I wish it was that logical, but the tanks aren't going to make sense in future wars either. They're just too heavy. They previously had to re-enforce bridges in Europe so that the tanks could act as a defense if Russia invaded.

We sold some of them to Australia, and they struggled to get them off of the docks as the trains and bridges couldn't handle the weight.

Unsurprisingly, the military has asked for lighter tanks.

I had vague ideas, a few years ago, of integrating a keyboard into the handlebar of a recumbent tricycle (it would need to not interfere with braking, but there’s a fair bit of leeway left for useful design). Modelling clay had indeed not occurred to me! Nor had I realised how chorded keyboards could hook directly to GPIO pins. If I’d seen this back then, I probably would have gone ahead and prototyped something right away. Alas for this vision (though not alas in general!), I got married instead and my long-distance cycling days are behind me. But I’m still rather tempted to play with this, it looks fun and surprisingly straightforward, even if I can’t immediately see a good practical purpose in my life. Just last week I happened to see a box of epoxy modelling clay and wondered what it would be like to use… though I suspect it might harden too quickly for this.

People continue to use these limitations. A long time ago when multicore CPUs were new or even systems with multiple CPUs saw vendors charge higher fees to allow their software to run on more than one core/cpu. My first run in with this was transcoding software with the license running ~$5k per core. To them, it was a whole second computer since everything was single threaded, so they felt it was worth twice as much. All it took was for someone else to not charge per core and took away business for that sales model to go the way of the dodo.

That's cool... I really should take a next step to bridge my home setup with my OVH server. It's a mixed bag, mostly in that the upgrade to "business" class from home is more than what I pay a month to rent the full server and IP block on OVH... But I've got a relatively big NAS at home I wouldn't mind leveraging more/better.

Aside: I really want to like NextCloud, but as much as I like aspects of it, I don't like plenty as well.

I had an exec at a tech company once send out an email with the subject line "Important." All there was, was an attached .docx file, and a sentence saying to read it immediately. This guy should have been fired for this level of incompetence. No, it wasn't a phishing test.

Then Microsoft sends out e-mail advertisements with fucking QR codes in them to everybody to get people to install software without IT department's knowledge. So you not only can't see the link, you can't even de-obfuscate it by hovering over it.

There's a really easy fix for this. It's so fucking easy it hurts my brain.

Disable HTML e-mails. Disable hyperlinks. Feel free to send URLs, but make people copy and paste the link. This way they have to at least select the link. When they get a 6000 character link and can't copy paste it? That's good! Because they have no idea what the link actually is.

Nobody will do it, and I don't get why not. Do you really need to market to your internal employees so badly with images and links? That's what a portal is for. Post updates on your portal and stop bombarding my goddamn email box.

> They run it like a propaganda outlet, only allow approved thought from approved commenters, and ban anyone who steps out of line with the mods.

When almost any community is particular about who it lets in and who it doesn't let in, it can be seen as a reasonable moderator precaution. Heck, some of the very best social spaces I'm a part of are only accessible by knowing people who know people.

But Reddit at it's core is a content aggregator with a comments section, which uses a moderation model driven by a strange mix of authoritarian mods and mob rule. A mod can ban you for any reason, but there's nothing stopping an outside mob from trying to control a narrative by mass voting in a way that mods have little to no control over.

In practice, /r/conservative can't really be considered a functional social space. But this core contradiction at the heart of the Slashdot/HN/Reddit model means that none of them function very well as social spaces either. These days, the actual "community" part of most hobbyist subreddits are on alternative platforms like Discord, and quite frankly I think it's for the better that this is happening.

There’s been a long-running Internet movement to cast the beta-amyloid and beta-amyloid/tau hypotheses as an evil plot by scientists to siphon money away from research that works. It’s a whole thing.

Okay, this is helpful and definitely aligns with what I've heard. The proprietary protocols problem keeps coming up.

Is there any chance we can connect for me to ask a few more questions or read some of your reporting? My email is in my profile.

That's because you're doing web stuff. (I/O limited). So much of our computing experience has been degraded due to this mindset applied more broadly. Despite a steady improvement in hardware, my computing experiences have been stagnating and degraded in terms of latency, responsiveness etc.

I'm not going to even go into the comp chem simulations I've been running, or that about 1/3 the stuff I do is embedded.

I do still use python for web dev, partly because as you say, it's not CPU-bound, and partly because Python's Django framework is amazing. But I have switched to rust for everything else.

> Where's the animation studio cranking out Pixar-quality movies as weekly episodes?

Check out Neural Viz. Unthinkable for one guy without AI. And we're still in the Geocities stage of this stuff.

A non-Pixar animation studio, with presumably a >10x lower budget than Pixar itself, cranking out weekly Pixar movies would be like >1000x acceleration. And indeed, that's not a thing yet for animated movies. The example I gave shows that it's already quite a big X, though.

I definitely feel the "bad at asking questions" part, a lot of times I'll walk away for a second while it's working, and then I come back and it's gone down some intricate path I really didn't want and if it had just asked a question at the right point it would have saved a lot of wasted work (plus I feel like having that "bad" work in the context window potentially leads to problems down the road). The problem is just that I'm pretty sure there isn't any way for an LLM to really be "uncertain" about a thing, it's basically always certain even when it's incredibly wrong.

To me, I think I'm fine just accepting them for what they're good at. I like them for generating small functions, or asking questions about a really weird error I'm seeing. I don't ever ask it to refactor things though, that seems like a recipe for disaster and a tool that understands the code structure is a lot better for moving things around then an LLM is.

Of the 13 authors, 3 are at Anthropic. Of the 4 core contributors, 1 is at Anthropic.

Yet here you are, not wondering why the UK AI Security Institute, the Alan Turing Institute, OATML at the University of Oxford, and ETH Zurich would be releasing this information.

So I suppose the press release did the job it was supposed to do.

(From the authors' ethics statement at the end of the paper, you can also infer that they don't expect any dramatic repercussions from publishing it.)

I'm equally confused at just how bad Reddit is at identifying and removing bad actors to the point that I'm convinced it must be an intentional.

I'm not sure if the reason may be as simple as the desire to pump their user numbers for earnings, or if it's something more egregious than that. It's not clear to me how a company owned by the public which relies on advertisers for revenue has been able to carry on for so long being a propaganda farm for foreign agents and marketing bots.

If by one day, you mean one day and night, since elected officials make all the important decisions at 3 a.m. When you give someone the job of managing billions of dollars of resources and pay them less money per year than their mortgage costs each month, what do you think they're going to do? Be a hero who protects the people from corporations? That's what everyone on this site seems to think politicians do. But the people don't pay them anything. So what makes you think they're looking after you, and not themselves? The only way they can survive is by feeding off the public. Unlike corporations, they do it through force and involuntary exchange.

Incidentally, these powered USB hubs are pure gold if you do any embedded development.

Plenty of USB-A ports (of which MacBook Pro owners get exactly zero, because courage, and Tim Cook doesn't have any USB-A devices) — absolute requirement for any embedded development. Powered, so you can run plenty of stuff without additional power supplies. And individual button for switching ports ON/OFF, which is a godsend when you need to reset a device or test a reconnection.

Maintaining was painful (strongly disliked when an Action would start failing for unknown reasons, forcing prioritisation of the Action over the app and users).

But setting up a useful CI/CD pipeline was the worst part. The tl;dr is installing everything and getting system tests (i.e. tests using a browser) to work was just excruciating, partly because of the minutes long cycle time between making changes in the yaml, committing, pushing, clicking and waiting for it to fail. The cycle time was the killer. (if you could reliably run GHAs locally, my opinion of them would be completely different - and I tried Act, but it had its own problems, mostly related to its image and dependences being a bit different to that used in GHA).

The only anti-phishing program I've ever seen that was even a little effective was at one company I worked at, where there was an ongoing phishing test.

Users were randomly selected to get the test, and each phish was hand-crafted to trick people specifically at our company (but using only publicly available information). Anonymized results were posted quarterly, divided by department.

I only got fooled once, but man, it felt so bad to see Engineering show up on the dashboard with one hit that quarter.

(Sales was usually at the top of the list, which makes sense, since they interface with a lot of folks outside the org)

People are criticizing mouse models of AD. There is understandable given the confusion of the roles of animals models in disease. Let me explain:

First, the very name, ‘animal model of disease” is misnomer, and the cause of most of the confusion. Animal models are more accurately described as ‘models of mechanism’.

Second, while mouse are different from humans and how a disease manifests is different as well, many of underlying mechanisms that drive a disease share strong similarities across species. Mice, rats, dogs, pigs, humans etc… all share the same fundamental building blocks and cellular/tissue/organ mechanisms. Studying how a disease or even partial aspects of a disease manifests in, say, a mouse, can offer extraordinary insights in how the disease may manifest in humans. This can provide a strong experimental basis for potential therapies in humans. (A rough analogy is the field of software is that different programs can use the same functions. Understanding how a function is misbehaving in a simple program can provide insights in how it is misbehaving in a more complex program.)

Third, many diseases are difficult or impossible to study in humans. Alzheimer’s is a good example as the progression occurs on a timescale of decades. Further, we obviously can’t go around cutting out brain tissue from live humans.

It’s a big topic, but hopefully my brief outline provides some context for the use of animals models. We scientists also use cell and organoid models, which, while lacking key details of animal models in unknown ways, can provide insights as well.

So, when Anthropic had that huge release day, with Sonnet 4.5, Code 2.0, etc, this was one of the things they published: https://www.anthropic.com/news/context-management

> The memory tool enables Claude to store and consult information outside the context window through a file-based system. Claude can create, read, update, and delete files in a dedicated memory directory stored in your infrastructure that persists across conversations. This allows agents to build up knowledge bases over time, maintain project state across sessions, and reference previous learnings without having to keep everything in context.

This is what made me think that it came out with the 2.0.0 release. But apparently /memory landed in 1.0.94. Frustrating!

(Can't read the article due to paywall and no working mirror on archive.is right now.)

I mean... duh? This shouldn't be news to anyone paying attention. DOGE was shock-and-awe theater, and a means to shake up agencies and gain access to sensitive information. At best, they saved a few tens of millions of dollars, which at that level isn't really worth the effort.

The GOP always cries about spending and the deficit, but when they're in charge, they spend just as much as Democrats (if not more!), and, to make things worse, cut taxes (usually for the rich more than anyone else). The largest part of the federal budget isn't the discretionary spending, anyway.

And the effects of the tariffs have been obvious to anyone not drinking the MAGA Kool-Aid.

Sure it does! ReiserFS's popularity went way down after he murdered his wife.

And that's only from murdering one women and no children or men, so Reiser count of one kill (and holding steady) can't hold a candle to Netanyahu's mass murder kill count, which is rising fast by the day.

> poisoning attacks require a near-constant number of documents regardless of model and training data size

I fear this takeaway could be misinterpreted by non-experts.

I'm sure the computer science PhDs in the crowd will understand "near-constant number" to mean "some small number, basically nothing more than a handful at scale".

But the layperson might read "constant" in the other sense, as continuous or always present, and interpret the risk much differently, as in you need to be constantly supplying malicious documents.

I would urge them to use different terminology.
