I meant safety critical, although a similar design decision is often made for time critical behavior.

In some cases, e.g., for IEC-62304 compliance, software is designated as various safety classes based on likelihood of causing Harm. If you can extract the more safety critical software from the rest of the system and prove that it is sufficiently segregated (e.g., by putting it on a separate processor), you can substantially reduce your Verification and documentation burden.

I've used systems that did this (some TypeScript TUI library comes to mind) and was similarly confused. I think what actually happened was that the x function/getter/whatever had some 'magic' in it that let it communicate with `Computed` as a side-effect of `Computed` computing the value.

Too magical for me. I'd rather have something like you described where inputs are explicit, so I don't have to guess about whether the magic will work in any given case.

There's nothing wrong with eating saturated fat, cholesterol, and sodium.

I've known people who have diabetes eating industrial potato chips telling me they stay away from butter and eggs and red meat because of the cholesterol and saturated fat. It's backwards.

These are natural parts of real food that have been eaten in significant quantities by humans for many tens of thousands of years.

I haven't gone as thoroughly into the literature on saturated fat but I don't think I need to. The few studies I've looked at had basic obvious flaws. Saturated fat made up a big part of people's diets in many regions, long before the modern epidemics of diabetes and heart disease. Personally I've been "gorging" on it for ten years now and am in excellent health.

I did look at many of the papers used to say sodium is bad and found that that is not a valid conclusion from those papers. Of course don't overdo salt but the problem shown by most of the studies is probably with processed food which has a lot of sodium, not the sodium itself.

Any incoming revenue, whether from sales or investment is theoretically taxable as income unless the company can show that it was used for an exemption such as an op-expense. This rule classifies dev salaries as cap-ex which have a different exemption process. “Profits” are just revenue minus expenses, the question is what is an expense. This rule classifies some expenses in a modified way that lowers the annual amount of the company’s expenses raising their tax liability.

But the point is that if you've got reflection (and an expressive base language, and a powerful enough type system, etc), you probably don't need macros. They're a heavy mallet when you almost always need a more precise tool. And the result of using macros is almost always worse than using that more precise tool - it will be harder to debug, it will play worse with tools like LSPs, it will be more complicated to read and write, it will be slower, etc.

I think macros are a necessarily evil in Rust, and I use them myself when writing Rust, but I think it's absolutely fair to judge macros harshly for being a worse form of many other language features.

Call to action: "Stop using the Anker PowerCore 10000 (model A1263) power banks immediately and contact the company for a free replacement".

> The recall covers about 1,158,000 units that were sold online through Amazon, Newegg, and eBay between June 2016 and December 2022. The affected batteries can be identified by the Anker logo engraved on the side with the model number A1263 printed on the bottom edge. However, Anker is only recalling units sold in the US with qualifying serial numbers. To check if yours is included, you’ll need to visit Anker’s website:

>If Meta is known for anything besides user privacy violations it's for taking risks that often pay off. [...] Their continued bet on VR is still highly criticized, yet they were the first Big Tech company in the space, they're the current market leaders, and I'm sure it will have huge ROI in the near future.

Are you using something that hasn't yet paid off as an example of how their big risks often pay off just because you are personally sure it will have huge ROI?

But I'm not actually sure I agree with the premise.

What risks is Meta known for taking? Instagram and Whatsapp purchases were defensive moves; they were laughed at for the prices not for risk.

Here they are similarly being laughed at for the price.

Is there much risk beyond that?

If Instagram had petered out and people had stayed on Facebook proper, they would've been fine. Same with Whatsapp. It's not like they've been trying to push people away from their core Facebook product. More the opposite - they've used acquisitions to try to push Facebook accounts to more people.

Compare to Apple, letting Mac software flounder for a while while focused on growing the iPhone and iPad business. Risky, worked out. Compare to Microsoft, going down years of dead-ends trying to come up with a next-gen operating system - a big part of their core bread-and-butter - and then having to release the generally-panned Vista because they bet too big on stuff they couldn't realize with Longhorn. Risky, failed. Compare to Snap, even - turning down Meta cash for independence. Risky, kinda meh results? But adding another social media app to a social media company's portfolio? Less so.

VR, on the other hand, does seem like the closest analog here. Buying their way into a non-core-competency space. There they bought the undisputed leader but it still hasn't paid off to date. Here? Eh....

I hear you, but it's also a reality that more people in our field have heard "battle tested", know what it means and understand the French translation than "épreuve du feu" (I genuinely only ever read that idiom, and not once since the horrible movie which got that as the French name).

That's where I'm saying going back to an older idiom just makes it classic, and doesn't help communication in itself IMHO.

A few possibilities:

1. Mark no longer wants to run the company and he is picking alexander wang. 2. Mark believes that Ai is the top priority, his teams have failed, (this is all clearly true so far) and he wants completely change the org structure of his AI efforts (not recommendation but everything else). 3. Mark wants to cut off the supply of information to other labs 4. Mark thinks that full access to ScaleAi's data could accelerate their research and somehow they couldn't do this with a less expensive options.

(2) seems semi-reasonable (in that Meta has failed with near infinite resources) but acquiring a handful of execs for this price seems absurd.

(3) seems like a conspiracy theory and the technology is moving away from this path of data collection, although it is still important at this very moment.

(4) Maybe.

I guess some combination of all 4 is plausible. But the amount of money seems, frankly, absurd.

It depends on acceleration though. If acceleration and deceleration take long enough, it could take an entire generation to get up to a fast enough speed that relativistic effects make any difference, and another generation to slow down enough to interact with anything you might see.

Plus if you're traveling at near light speed, running into any matter at all would be pretty devastating for whatever craft you're in.

Edit: someone further down claimed that the math says that accelerating at 1G would get you to 0.1c in a month, so that's actually not that bad all in all. I still maintain that hitting any matter at those speeds might be unpleasant.

I belonged to an organization that had password complexity requirements. That's normal and understandable. However one requirement was that no part of my password could contain a three character subsstring that was included in my full name. I won't give my real name here, but sadly it includes some three letter subsequences that are somewhat common in many English words. I can understand a policy that prevents someone from using "matthew1234" as Matthew Smith's password, but this rule also prevents such a person from using "correcthorsebatterystaple" because it has 'att' in it.

Turns out, this rule was not from IT. It was a requirement from the cybersecurity insurance policy the organization had taken.

Yeah this is true. I could have sent the entire book up until that point as context. But doing that 100 times (once per chapter) would have meant sending roughly 50x the length of the book as input tokens (going from 0% to 100% as the book progressed).

This would be fine for a cheap model, but GPT 4.5 was not cheap!

I would have liked to have fewer, longer chapters, but my (few) experiments at getting it to output more tokens didn't have much impact.

People do - but the actual answer to your question is as you’re implying: it’s not as simple as “you get paid to consume”.

There are negative spot prices in Europe all the time - but they are not usually negative enough to make up for the grid fees and taxes. Or they are in countries like Germany that hasn’t rolled out smart meters, so consumers have no way to access spot prices

Nope, I'm completely unaffiliated with Kagi, just a happy customer for a year and a half or so.

I don't understand all of your objections, but it sounds like you're operating in a very strict "if I can't verify it myself continually, then I don't trust it at all", which I think is far too black-and-white. Trust exists on a scale, is built up slowly over time, depends on your threat model, etc.

I don't want an adversarial relationship with my search engine where they try to show me enough ads to make money to stay afloat and I try to block enough ads so my experience isn't miserable - this isn't any fun, and one of us will lose.

On the other hand, I can pay Kagi, and they are incentivized to give me the best service possible so that I continue paying them and recommend them to others. It's far more positive, and a better outcome for us both. And it's working - I have a much better experience on Kagi than Google or elsewhere, and I have kept paying them and recommending them to others entirely organically - I don't think there's even a referral program, I'm certainly not using one.

They say they don't collect my data, and why would they? They don't show ads, and if anyone ever found out they were lying their paying customers would leave in droves. Furthermore, they take actions to back up their claims, like integrating the Privacy Pass feature.

Finally, they don't allow you to modify your website ranking for others - they let you modify how other websites rank for you. You get to personalize how you want websites to be ranked for you when you make a search, which is a very cool feature.

Anyway, if you tried it and didn't like the search results, no problem! You can use something else. I don't think that your other objections are valid, though.

For decades before 2007 it was flat. The USA went "genuinely bad" during the financial crisis and never recovered.

The drop in value of the USD aka inflation was due to money printing during covid. Not the tariffs. That's a lie.

1. Do favors for them where you can, based on your strengths (and perhaps their weaknesses.)

2. Pay it forward by doing the same for someone younger. That's probably the main thing your helper wants: to continue their help "blood line".

I had a few crucial people boost me in my youth. And I did the same for some younger people. My messaging to them was not to pay me back with favors, but to continue the thing.

But yeah, they've helped me in a pinch a few times and I've really appreciated it.

It's handy to be in a situation where you have a lot more skills and experience and wisdom, but they are much more intelligent.

Rust will probably become usable with custom tracing GCs (which is helpful if you're dealing with general graph-like data but still want the highest performance as far as practical) way before this effort reaches genuine feature parity with Rust. Not seeing much of a point in this, unless they perhaps intend to focus on the lowest-hanging fruit and have big O(x)Caml codebases that they care about.

I don’t think either Demis or Ilya are available for $15bn. They’re already both comfortably billionaires. Demis seems a sensible candidate for heir to the top job at Google in the long term. Ilya is away focusing on super intelligence.

It’s not clear to me why either would take a subservient role in a company flailing incoherently around AI, rather than stick with the incredibly high-leverage opportunities they both have now.

>Even when a battery is completely drained in an electrical sense, it retains a lot of chemical energy that can be released if things go wrong.

That's basically just saying "you can burn anything" but in words that are attrativce to the audiences biases.

Yeah, there's a bit more to go wrong with a dead battery than the plastic and whatnot device it's in but if it can't ignite itself it can't ignite itself and that's more or less the end of the story.

> alpha - deprecated 2015~2016. unrelated to the new engine! view the new engine here - https://luxeengine.com/

Also, that old version used to be open source, but I think this new one isn't anymore. Old thread mentioned by @pvg still mentions being open source, but right now the repositories only have docs.[1]

It's possible that my mom was not the dummy I thought her to be in that moment. She might have played a sleight of hand where she unplugged the cord and cut it almost at the same time. My memory of that event is hazy enough that what I remember was thinking how crazy dangerous what she did was -- I might not have checked if the plug was still in the socket.

What do you eat in those extra 200 calories?

I sometimes binge on cheese and nuts or peanut butter when I'm not at my best, but even when I do this for weeks, and I'm talking an extra 2000 calories in a day which is easy with those things, I haven't gained weight (fat). I don't feel as good and I don't recommend it, but I think it's safer than eating sugar if one is going to binge. I had a couple years 10 years ago where I ate sweet things most days and did gain noticeable weight (fat). So it's not like I'm genetically not going to gain weight either.

As an aside, physical activity might not affect weight change as much but it will affect the fat/muscle ratio.

I didn't know Dan personally, but everyone I know who knew him said Dan was good people. I wish I'd gotten to know him.

Piling-on your story: I'd love to know who the guy was I hung out with at Defcon 3. My friends' flights were earlier than mine and I ended up alone in Las Vegas, newly-turned 18 y/o and w/ very little travel experience outside of Ohio.

I ended up hanging out talking with a Unix hacker in his mid-late 20s who struck up a conversation w/ me on the con floor. We hung out the rest of Sunday until my flight left. It made what otherwise would have been a lonely and stressful day a lot of fun.

He gave me an email address to hit him up after the con. It turned out to be fake. I've never been able to find any references to his "name", the domain name on the email, etc. I don't know if he gave me the fake address because of the stigma of a "hacker con"(being worried about real identities, etc). I hope it wasn't because he just didn't want to hear from me again (albeit I do recognize I was pretty insufferable at that age).

If you remember hanging out w/ a long-haired kid on the last Saturday of Defcon 3 I'd love to touch base. (My God... that will be 30 years ago in a couple months.)

The key to unlocking a 10x improvement to compilation speeds will like be multithreading. I vaguely remember that LLVM struggled with this and I am not sure where it stands today. On the frontend side language (not compiler) design will affect how well things can be parallelized, e.g. forward declatations probably help, mandatory interprocedural anaylyses probably hurt.

Having said that, we are in a bad shape when golang compiling 40kLOC in 2s is a celebrated achievement. Assuming this is single threaded on a 2GHz machine, we 2s * 2GHz / 40kLOC = 100k [cycles] / LOC

That seems like a lot of compute and I do not see how this cannot be improved substantially.

Shameless plug: the Cwerg language (http://cwerg.org) is very focussed on compilation speeds.

Bringing up Oculus and VR is quite fitting, because I think it's the same problem. Meta is attempting to find their next business, but like with social media they don't really have a plan. It worked out well with Facebook and some of the purchases surrounding social media, but it was never a clear path to profit, so they slapped ads on it.

Why does Meta want VR to work? Create the Meta-verse? We're back at why, what problem does it solve? Same with AI, what's the goal here, besides being an AI company?

Why link to this copyright maximalist site with paywall? They argued against copyright in 2001 (NYT vs Tasini) when it was in their favor, and recently pro copyright (NYT vs OpenAI) because it was in their ..favor. They want to put restrictions on our creativity, to extend copyright from expression to abstractions. I would not touch it with a 10 foot pole.

Multiple issues. One of them is reluctance of younger hiring managers to hire older people. At 35 you don't necessarily see advantages that hiring 50 year old will bring you, as you don't have experience to be able to see that.

Not sure if there is a "solution" for that as a 35 yo hiring manager will probably have an easier time managing under-35 individual contributor comparing to a 50 yo one. Different perspectives, experiences, etc. So by hiring younger IC the manager makes a correct decision. Sucks for us older folks but that's life.

Not caused by the tariffs, no. The timing is wrong.

But the tariffs are (going to be?) higher than companies will be willing or able to eat out of their profits. There will be price increases because of the tariffs. That won't be inflation, it will be a tax increase. That is, the dollar won't be worth less (measured against other currencies or gold or whatever), but everything will cost more.

There's a CRPG I've been meaning to play where this is basically the plot; there was a generation ship, it was heading towards some planet or another, but the social and political structure on the ship broke down at some point and now there's no one actually in charge, the ship is getting run down, and they probably blew past their destination a hundred years ago if they were even still on course at all.

I remember someone pointing out that a generation ship could be problematic because you have one generation who decides to launch this expedition but will never see the end, multiple generations who didn't choose this life and won't get to see the benefits, and then one generation who actually gets to the planet but might not even want to be there. Without some kind of cryogenic sleep or relativistic speeds the whole thing might fall apart just because most of the people involved "didn't sign up for this" but they have to toil away anyway for someone else to benefit from it.
