Meta have laid off talent, not "low performers"
Yesterday I started to hear from friends and people I used to mentor that they’ve been laid off by Meta.

The press says it’s “low performers” and the by people I know are anything but - if we had the funds to hire right new we would, no questions no interviews because I know how good they are! A couple of them are 10x’ers, so “low performers” my hat.

Some of these people were on teams bought by Meta because they were out-performing Meta, and some of them had pretty tasty golden-handcuffs to incentivise them to stay, simply because they were that good! Most of them passed some pretty rigorous interviews and were placed on pretty cutting-edge teams, so to call them “underperforming” and imply they’re the bottom 10% is incredibly damaging and untrue.

It’s also likely a marketing play giving energy to one of the classic tropes in tech, that “only the bad ones get fired” and “I’ll be safe because I’m good” - that is, ignoring the imposter syndrome that we all get.

From what I’m seeing the reality is that Meta have made cuts on tech they no longer feel is valuable, like the Metaverse and AR, then painting a picture like it’s the fault of the poor people they’ve let go for being “low performers”. Not cool and I really feel for everyone who’s been affected. Sad times.

Ohhh I wonder if there’s class action lawsuit in the cards for “slander”.
This is very much a fire and forget thing. Install takes 2 hours and then generates electricity for years.

Electricity is rather cheap anyway. If you don't heat/cool water or the house with it, electricity cost in Germany is less than 100 EUR per month for a family of 4.
Capitalism is bad because Elon won the game. Never mind that Sam Altman is a board member of the same non-profit he is trying to sell to himself for pennies.
This is wrong on many levels. There isn’t much effort put into preventing those kind of attacks outside of really dense venues like stadiums.

Train and subway stations rarely have more than one or two armed officers if they have any at all.

Train tracks have shockingly little protection to prevent timed derailment sabotage. Buildings have little protection from being surrounded by accelerants and set on fire, etc.

There is a strange subset of things terrorists seem to want to do and society doesn’t do much to prevent the rest.
if what they are doing is illegal, it seems like a slam dunk for their opposition to sue them and win a huge fat settlement $$$.

I made this html editor with instant preview and it turned out useful when I show friends how make their very first html page:

https://no-gravity.github.io/html_editor/

Originally, I made it for myself. To quickly do HTML/CSS/JS experiments. And I still use it for that use case.

Often when I show it to non-developer friends, I can see how they light up to coding for the first time. I think it is because it is so accessible. No signup, no setup, no long page load. Everything is instant, and they see each change the moment they type it.
You skipped the "you get a popup" part, which is an important and missing feature. Windows firewall only does popups for opening ports.
It should be randomly selected and that would solve all the issues.

Interestingly, owning even a small PV setup like these "balcony solar" devices, and monitoring its output, causes many people to think more about their grid power consumption, and to reduce it or adapt their usage pattern to solar energy availability to some extent. There is something like gamification going on.

I think I'm mostly with you except a couple things.

> Are the scientists interacting?

So say Alice and Bob interact, forming an event in RQM. Then they both separately interact with Charlie, generating two new events. These two new events are, in general, related (correlated) to each other, because they may be causally influenced by the original event. (For example, Alice tells Bob the number. They both send this number to Charlie.)

> Not hearing something, in any way, simply means you have not yet interacted with it. There has been no exchange of information. It doesn't mean it didn't exist.

My intuition agrees with yours here, but I think RQM is saying something different. The article says that in RQM, variables simply don't have any value unless a system acts on another system. Here is the relevant quote.

> Variables have values when a system acts on another system. More precisely, for a system S to have a variable A taking a value is to interact with a second system S′; the variable A characterizes the effect of a certain action on S′

And about the tree falling in the forest, I take it to be more of a metaphysical question about existence. In the real world, a tree falling is an extremely complex system and will inevitably interact with many other systems -- the air, the ground, like you said. But the heart of the issue is whether it's meaningful to talk about a tree which is somehow isolated from the rest of the universe.
Sounds like you've never been an expert, harassed by neophytes. For them it's eternal September. How would you handle that?

The resistance thermal coefficient of most¹ materials is positive, which is why parallelizing connectors works; contact points that heat up due to poor contact increase in resistance and therefore current shifts to other connections that have less resistance.

This is a plain case of having not enough contact area (or not having enough mechanical safety/UX to ensure full insertion.)

¹ most: pretty much everything that isn't explicitly researched/chosen for its negative coefficient. Definitely all conductor and connector materials. But some semiconductors are known footguns for not supporting parallelization due to negative coefficients and runaway heat effects (one of the things you learn in EE education).

P.S.: materials with negative thermal coefficient don't turn into superconductors if you heat them far enough; the coefficient is not constant across temperature and it's either just not linear and approaches some nonzero value, or it just flips to a positive coefficient at some higher temperature. Or the material just melts or burns and then behaves differently anyway.
Yes, but the LLM is roughly equivalent to lossy compression of the corpus it is trained on so why wouldn't you preserve that actual corpus so that it can be used to train some better LLM, or something better than an LLM, in the future?

(There may be a good answer to that question: perhaps, for example, the corpus can't be preserved for data protection reasons but the LLM trained on it can be preserved? For various reasons that doesn't seem very plausible, however.)
So heat depends on current, not on power. My research: https://www.reddit.com/r/ElectricalEngineering/comments/15xf...

Building MUD:s is really fun.

https://github.com/michaelprograms/nightmare-residuum is a fine starting point, and I'd recommend playing discworld.atuin.net 4242 to get some ideas.
It is also fun to engineer servers which can be upgraded without ever stopping listening, even for a nanosecond on the listen socket. Would be a fun senior C programming job interview question, but unfortunately those don't exist anymore. Only kubernetes pod wranglers do, where the answer is "destroy it all and create it all and hope that the ingress somehow hides the mess".

Sigh.
Well, of course. Realistically, I would not expect AI systems like this to be very useful for novel cutting-edge scientific results, proving mathematical theorems etc. in the next few years.

But this is not the majority of what software developers are doing and working on today. Most have a set of features or goals to implement using code satisfying certain constraints, which is what current reasoning AI models seem to be able to do very well. Of course, this test was not rigorous in any meaningful way, but it really changed my mind on the pace of this technology.

Interesting, considering they are not making anywhere near 250. doo de doo... How exactly are you measuring "delivered", "enough", and "justify"? I guess you just feel it like that 250k.
And the card requires up to 600 watts, which is 50 amps if the supply is 12 volts.
No it depends on power, but the power dissipated by the cable, not the power through the cable. The power dissipated is i^2 * r, where r is the resistance of the cable and i, crucially, is the current through the cable which depends on the power it's supplying (which with a resistive load, in this case, is i * 12v).
The argument was put for that Elon is an exceptional mind when it comes to capital allocation. My counter-argument is that to have Elon's success, you don't need such an exceptional mind, but it may seem exceptional due to the selection bias of people who typically have accrued wealth. There may be vastly more people with such purported competency of capital allocation, but we'd simply never know because they are less likely to find themselves wealthy in the way that Elon did.
That it circumvents Yao’s conjecture by being non-greedy contradicts the article. Is the article wrong or is your understanding of the paper? I don’t know, just want to see if you’re noticing something the article’s authors don’t know.

This shit is so fucking dumb. Sorry for the unhinged rant, but it's ridiculous how bad every single connector involved with building a PC is in 2025.

I'm just a software guy, so maybe some hardware engineer can chime in (and I'd love to find out exactly what I'm missing and why it might be harder than it seems), but why on earth can everything not just be easily accessible and click nicely into place?

I'm paying multiple hundred dollars for most of these parts, and multiple thousands for some now that GPUs just get more and more expensive by the year, and the connector quality just gets worse and worse. How much more per unit can proper connectors possibly cost?

I still have to sit there stressing out because I have no idea if the PSU<->Mobo power connector is seated properly, I have no idea if the GPU 12VHPWR cable is seated properly, I'm tearing skin off my fingers trying to get the PSU side of the power cables in because they're all seated so closely together, have a microscopic amount of plastic to grip onto making it impossible to get any leverage, and need so much force to seat properly, again with no fucking click. I have no idea if any of the front panel pins are seated properly, I can't even reach half of them even in a full ATX case, fuck me if I want anything smaller, and no matter what order you assemble everything in, something is going to block off access to something else.

I'm sure if you work in a PC shop and deal with this 15 times a day you'll have strategies for dealing with it all, but most of us build a PC once every 3 years if that. It feels like as an average user you have zero chance to build any intuition about how any of it works, and it's infuriating that the hardware engineers seem to put in fuck all effort to help their customers assemble their expensive parts without breaking them, or in this case, having them catch fire because something is off by a millimetre.

This space feels ripe for a radical re-design.

Show HN: An AI-powered book software to write a book in hours
Hey HN,

I'm an author and I spent 2+ years writing my first book and getting it published.

After my experience, I realized that 99% of all business books follow the same structure.

So, with the rise of AI solutions, we asked ourselves if we could simplify the process to help first-time authors achieve their dream of writing and publishing a book.

Together with a friend, we created First Book ai.

Now, we can create coherent, full-size books in hours, saving first-time authors years in the process.

We hope this tool will be helpful for as many upcoming authors as possible.

Would love your feedback pls

Can you explain a bit further? How's it helpful to delete your writing? I never considered writing and deleting.
GCP got this reputation because it’s a second class citizen within Google. Google’s own internal infra (Borg, Blaze) is top-notch.

If Meta can pull off the public cloud correctly, I’d trust them greatly - they’ve shown significant engineering and product competence till now, even if they could use some more consistent and stable UI.
As a Jew there’s no difference to me between those who knowingly repeat Nazi slogans (i.e AfD) and “real” Nazis. It’s very easy to not be a Nazi, it’s unnecessary to make excuses for those who know what they are doing.

Germans (i.e. ethnic German citizens), should be held to a higher standard, because they are educated on this, there’s no excuse.

There's a similar phenomenon in ocean shipping called Slow Steaming.

https://en.wikipedia.org/wiki/Slow_steaming

First, the hull shapes of container ships are tuned for a particular cruising speed. They accelerate up to that speed and cruise across the Pacific. In particular, the ship's bulbous bow is shaped to create an efficient counter bow wave at that speed.

Before 2007, that cruising speed was faster, maybe 27 knots. This is just like the 707 doing 525 knots in the article. It was faster but not efficient.

Enter Slow Steaming. They redesigned the hulls for a lower cruising speed, maybe 18 knots. They actually took ships into dry dock and re-nosed them. The result was better fuel economy. Fewer shippers (some still are) were willing to pay extra for the 27 knot speed. With Slow Steaming, the results are lower costs and significantly less pollution.

The economics of flying and shipping are largely the same in this case.
This connector somehow has it's own Wikipedia page and most of it is about how bad it is. Look at the table at the end: https://en.wikipedia.org/wiki/16-pin_12VHPWR_connector#Relia...

The typical way to use these is also inherently flawed. On the nVidia FE cards, they use a vertical connector which has a bus bar connecting all pins directly in the connector. Meanwhile, the adapter has a similar bus bar where all the incoming 12V wires are soldered on to. This means you have six pins per potential connecting two bus bars. Guess how this ensures relatively even current distribution? It doesn't, at all. It relies completely on just the contact resistance between pins to match.

Contrast this with the old 8-pin design, where each pin would have it's own 2-3 ft wire to the PSU, which adds resistance in series which each pin. That in turn reduces the influence of contact resistance on current distribution. And all cards had separate shunts for metering and actively balancing current across the multiple 8-pin connectors used.

The 12VHPWR cards don't do this and the FE cards can't do this for design reasons. They all have a single 12 V plane. Only one ultra-expensive custom ASUS layout is known to have per-pin current metering and shunts (but it still has a single 12 V plane, so it can't actively balance current), and it's not known whether it is even set up to shut down when it detects a gross imbalance indicating connector failure.
Oh, this thing is perfect. Thank you.
I think the problem with this is that chips can only use a relatively low voltage around 1-1.5 volts. So if you supply 48 volts to the card it still has to be stepped down and this means more components and heat dissipation on the card. We are basically arriving at the idea of graphic cards having their own integrated PSUs, but this doesn't fit well with the current physical design of computers.

> I'm saying it is essentially impossible to spend these amounts of money on things that personally benefit you

This bit changes my reply, I have to agree with that. The rest though - yes the normal way to build a tunnel would be to make sure it will be financially profitable and get investors, but what I'm saying is that a UK-Ireland tunnel would not be profitable. One estimate said it would cost double the UK-France tunnel but get 20% of the use. Nobody would "invest", it would have to be funded personal money as a passion project just because they want to see it exist in the world.

> The problem is, your money makes money too fast. For most things, faster than you can spend it. Every second you aren't spending it, it grows.

Nice problem to have, lol. Seems like it would be possible to invent as many megaprojects as one wanted in order to get rid of enough money, but maybe it isn't. Maybe the limit is how much attention one person can have. Maybe the balance of trying to start enough to use all your money without bankrupting yourself if one overruns costs and then never finishing them all, would be too hard.
Yeah sure, in the pandemic all people just did it for the money.
Same with all the voluntary fire fighters and all the other voluntary work.
That’s simply untrue. The old way was definitely better because, with OTA, the manufacturers will succumb to the usual web-software bullshit of “we don’t have to sell them something that actually works now, we’ll just push the update later”. I mean, it’s a car, I can easily take it to a garage and do so for anything else that might be wrong (if I can’t fix it myself) so I don’t see the problem in doing so for software patches. OTA doesn’t solve many issues for me but it sure as hell will create new ones.
Also, designers gotta justify their jobs.
I've tried that. I had an idea for a process checklist for GitHub Actions pipelines. Came up with it after seeing people complain online, also had the issue myself. I reached out to everyone I could find who complained about it. The 30% who replied said that they wouldn't be interested in trying out a solution.

I've come to realize that just because people express problems, doesn't mean they'll do something about it. You need to find something where the pain is urgent, and unsurmountable. And that's very tricky.
I'm a fan of Grafana, both the main tool and also the infrastructure projects they have been working on, they did a great service to the IT world. However, the pricing of their cloud service, that's some shady business. It goes from reasonable pricing to oh-my-god pricing so fast. I really wish they would introduce limits on their paid plans, but that's against their business practice.
