Agreed, something changed that made Slack usage across multiple devices much worse. Loading a channel tends to sputter as various state and messages load, messages I already read on different devices change state, it's pretty jarring to watch. The "unread messages" badge is often out of sync.

New audio statement by Prigozhin (00:03 BST), stating Wagner "crossed state borders in all areas" and is now entering Rostov, promising to "destroy anything standing in their way":

"The current situation: today, we were dealt a missile strike. After this strike, helicopters did their work. Then, artillery.

The orders were coming from the Head of General Staff to destroy PMC Wagner. After a meeting with the Minister of Defence Shoygu where they made this decision - to destroy the rebellious units, who are ready to defend the motherland, but not their asses.

As of now, we’ve crossed the state borders in all areas. Border guards came towards us and hugged our fighters.

Now, we’re entering Rostov. Units of the Ministry of Defence, in fact, the conscripts who were thrown to block our path, moved away.

We do not fight with children. We do not kill children. Shoygu is killing children by throwing untrained soldiers, conscripts included, into the war.

He set up 18-year-old lads against us. They’re like children and grandchildren to us. Therefore, these lads will live and return to their mothers.

We only fight with professionals. But if someone stands in our path, we will destroy EVERYTHING in our way.

We lend a hand to anyone. No need to spit in this hand. We are moving forward, going to the end.

Regarding claims regarding the arrest: this brotherhood, this justice, this honour, this conscience is what we have. But when you make these claims, you haven’t got these feelings. These feelings are destroyed. Thus, you cannot understand anything but betrayal."

Anybody competent I know, don't go around boasting about doing their jobs well. Your job doesn't define you, and you don't make it your personality in Europe. You do the job you're asked to do and move on. It's just part of your employment, not some major success. The ones who do boast are making up for their incompetence by pointing to their few successes.

I would argue that energy use per capita is not relevant if you're talking about the embedded energy of durable goods shipped across borders.

Similarly, differences in renewable percentages aren't particularly helpful when there is a large disparity in CO2 production by non-renewable type. Coal produces roughly twice as much CO2 per kilowatt hour As Natural Gas. Therefore, if you want to analyze the footprint of a PV panel, the composition of non-renewable fuel types used to manufacture it is very relevant. Something that is manufactured with 20% Renewables and 80% Natural Gas is comparable to something with 60% Renewables and 40% coal.

Comparison would be CO2 per kilowatt hour in China versus the US, which is 40% higher in China, at 530g/kwh vs 370g/kwh in the US. [1]

I know of at least one game on Steam that was built on React… because I made it :)

It worked great for a text-based programming game, but I’m sure more imaginative people can apply React to other genres.

I did have one big complaint, however: basing the whole game on React meant I was mixing state and UI together, so when I later wanted to port the game to the terminal, I had pretty much painted myself into a corner.
Unsafe Rust is safer than C++, and even if it wasn't, 5% unsafe in Rust programs (in well-marked locations) is vastly superior to 100% unsafe in C++ programs.

You guys are tall ship masters. Your vessels are generally well understood these days but let's not forget some comparable disasters: Vasa and Mary Rose. Yes both are from a long time ago but both were based on top of a lot of good solid engineering but both pushed the envelope somewhat and perished. Vasa design basically forgot to sort out the various CoGs for a ship - it was top heavy. Mary Rose loss is a bit more complicated but for me water ingress via lower open gun ports, compounded by heavier loading was a possible failure scenario.

I'll also recall the sinking of the Herald Of Free Enterprise - a roll on/roll off ferry that departed Zeebrugge and "rolled over" in shallow water due to the bow door being left open - ie stupidity and a lack of monitoring. That wasn't a tall ship but the same general rules apply.

Those are three samples from 400 years of maritime history. The Vasa was a daft design from the outset (meta vs cog), Mary Rose a daft refit after 30 years of service (it was OK for 30 years and then wasn't) and Herald was basically abused by her crew and lacked monitoring.

Now submarines are pretty new. We do have a fairly long history of making pressure hulls from steel and some other materials but they all build upon earlier designs and they have all been tested with a lot of loss of life for failed designs - the history of submarines is pretty sad.

I gather that all very deep sea hulls are basically spherical. The Titan's pressure hull was made of carbon fibre which I gather no one else has used like that. As well as a novel material its shape was elongated to allow more passengers - that's two changes. Finally we also have a viewing port at the front that was actually tested but never rated for 4000m.

No one really knows what happens to carbon fibre pressure hulls when they go from one atmosphere to 180 and back again, repeatedly, then they are picked up out of the water - more stress and strain. Also, no one really knows what happens at the interface of a "window" to carbon fibre at 180 atmospheres.

There are lots more questions to be answered but frankly I see a company trying to run a submarine with DevOps attitude (move fast and break things) rather than proper maritime grade engineering. At 180 times atmospheric pressure, you die within seconds. No ifs and no buts.

I absolutely stand with you guys in insisting on standards for this sort of thing. It isn't the same as running up Everest or going into space. Deep sea is way, way more dangerous.

it really is amazing. to be fair if you actually are following along and writing the code yourself, you have to stop and playback quite frequently, and the parts around turning the attention layer into a "block" is a little hard to grok because he starts to speed up around 3/4 through, but yeah this is amazing. I went through it week before starting as lead prompt engineer at an AI startup, and it was super useful and honestly a ton of fun.

This reminds me, a few months ago, a "real-time" chat app appeared on HN which would display your typing to a public chat room before you hit Enter. And people found ways to inject XSS into usernames, including images and JS popups. Does anyone remember the name and URL of the site? I think it would make an intriguing alternative to voice calls, which is more synchronous/immediate/interactive than a conventional IM app where the other person can only start reading a sentence once you've finished typing it.
It seems like it doesn’t hold since this relies on turning the whole thing into a piecewise linear function.
I was in the U.S. Space & Rocket Center in Huntsville a few weeks ago. We watched the Webb telescope presentation with a live comment in the planetary, and I could not believe how perfectly the presentation was done. Everything was absolutely flawless and I am almost sure that not a single person in Germany would be able to deliver a presentation on that level of perfection. It was not showmanship, it was just outstanding skill at doing a presentation, and I wish people in Europe would be better trained in doing this.
Computers should be for everyone not just a few tech elite people. I find this attitude that things should be complicated silly.

I was making the argument that you made an assumption that didnt hold any weight.

regarding doing what slack can do, I think we do have a bit of collective amnesia about what was truly good and truly bad about what came before.

Slack does a lot of things, but its UX is actually pretty piss poor due to the bolt-ons (threads is just about the worst implementation I have ever seen), walled garden, weird account things (magic links~ if you want to see your other workspaces make sure you use the same email everywhere!), security (goodbye decent realtime bot api) and the client which feels slow despite using more resources than it should given its status as a program that needs to always be running.

To take one example of a worse system: IRC scales to tens of thousands of users on a single machine; doesn't have emoji or picture sharing though- but the bot API is simpler for sure, you can connect in one click if the person has an IRC client (or you pass a webirc link) - no signup needed.

I think the problem with slack is exacerbated in europe (or rest of the world in general), where the latency of fetching thousands of tiny assets or chats is many-many times higher than in California.

Also; the reason I had to do that was because my mum wouldn't permit a home internet connection; broadband was a thing at the time. Dial-up was not mandatory in 2002. IRC with dial-up was faster than slack is today too; you can argue that slack “does more” though.
> I don’t think an old man in the room would have helped.

I guess in this case it actively hurt.
> You’re argument seems to be based around economically feasibility, not technical issues, right?

Economic feasibility due to engineering problems. Just because something can be done in a lab does not mean it can be done at scale. As an example, Musk with his stupid hyper-loop. Sure it is technically possible to evacuate a tube and send a vehicle through it at high speeds. It will never be economically feasible, however. Sometimes the engineers just have to say “not going to work” to an otherwise cool idea.

It’s not the cost of hydrogen production. It’s the engineering problems that pervade the rest of the handling, storage and distribution of hydrogen that look to be insurmountable.
> Obviously the standard library uses some "unsafe" as well, for instance.

Most beautifully, MaybeUninit<T>::assume_init() -> T

This unsafe Rust method says "I promise that I actually did initialize this MaybeUninit<T>, so give me the T".

In terms of the resulting program the machine is not going to do any work whatsoever, a MaybeUninit<T> and a T are the same size, they're in the same place, your CPU doesn't care that this is a T not a MaybeUninit<T> now.

But from a type safety point of view, there's all the difference in the world.

Even though it won't result in emitting any actual CPU instructions, MaybeUninit::assume_init has to be unsafe. Most of the rest of that API surface is not. Because that API call, the one which emitted no CPU instructions, is where you took responsibility for type correctness. If you were wrong, if you haven't initialized T properly, everything may be about to go spectacularly wrong and there's no-one else to blame but you.
It sounds like there was little reason not to get it certified. If it’s not regulated they could have just kept diving while working on certification. If their liability insurance provider let them dive without certification they probably wouldn’t have cared if they did that.

Users flagged it. We can only guess why users flag things. In this case my guess would be that they don't want the inevitable flamewar, as well as "If they'd cover it on TV news, it's probably off-topic" (https://news.ycombinator.com/newsguidelines.html). There can be exceptions to that (e.g. the recent submersible disaster story), but only if the topic can support an intellectually curious conversation.
What I’ve observed is more of a:

1) Identify biggest problem/opportunity in the company

2) Learn what is needed to solve it

3) Hire someone to take over what you’ve been doing

4) Repeat

Rather than any kind of topic based learning.
It would seem that in the future, people will be less inclined to proof-read their work, or even read it at all prior to submission.

I'd wager a guess that this will only get worse over time. LLMs will do more stuff for people - from helping school children to get through their homework, to higher learning assignments and all the way up to the "real" jobs. Along the way people might just place far too much trust in these tools. I'm pretty sure that's something we can all agree on.

What I do find striking here though, is the incredible laziness of the lawyers. Not even checking whether or not the cases actually happened? That's just bad lawyering. The AI actually helped the system to call them out on their bad lawyering.

That's not "bad things happening because AI" but just plain stupidity.
Where did you get the $31k figure? The CNN article mentions £400,000 ($560,000).

If you are correct about the $31k price, then it is definitely weird that Oceangate is so much more expensive. I assumed that Oceangate was attempting to make deep sea submarines more affordable.

I would just add the caveat that it is a single hidden layer. If you were to write this as a sequential model you would have something like:

nn.Sequential(

)

From this, it's pretty easy to see it is "two" layers but also from your equation c_i and a_i denote two separate matrix multiplications.

It requires quite some energy to build a rocket (you know, from extracting the matter from the Earth to having something that looks like a rocket on the launchpad), and then some more to fly.

There is no such thing as "green energy": even if SpaceX only used renewable energy, a) renewables are not zero-carbon and b) renewables are not infinite, so if you use it for SpaceX, you don't use it for something else, and that something else may well be using fossil fuels.

But let's be clear: SpaceX doesn't run 100% on renewable energy. So there's that.

Then, right now it is not launching rockets everyday, but I understand that the goal is to grow a lot. Create a whole new space industry. Just like one plane does not pollute that much on its own, if you take the entire aviation sector, that starts to make a lot.

I guess my point is generally that we are facing huge problems (peak oil, biodiversity collapsing, climate change just joining the party) that will probably destroy society as we know it. I don't think that pushing a lot more with a commercial space business is a good idea.

Reusable rockets are like the 5G for mobile comms: for the same usage, it requires less energy. But 5G will enable much more usage and hence it will use much more energy than 4G. Reusable rockets getting to 10M a launch... well rich people will be able to go have dinner in space, just for fun. That's not sustainable.

Some file selection dialog (and explorer) issues come down to the anti-virus. I've had folders on an SSD that took a minute (60 seconds!) to load. After I added it to an exclusion list in Defender it loaded in a second.

Another one that can be slow with file dialogs is that sometimes (maybe it has been fixed now) it will try to query whether a networked drive is around on another computer. If it isn't then the call to it can be blocking your file UI.

A third problem I've noticed with file selection dialogs and explorer is that the My Computer 'folder' that contains your disks takes a long time to load. Much longer than any sub-folders on any of the drives.

I think the problem is largely with explorer.exe. If I browse those folders in a web browser the experience is snappy.
