katmannthree··on Meta plans to cut thousands of jobs, after CEO predicted no more layoffs
Because the local environment is going to get more and more cuthroat and backstabby as people feel pressured.
katmannthree··on Meta plans to cut thousands of jobs, after CEO predicted no more layoffs
Oh absolutely, some of the mediocre employees will stay because of that. The exceptional ones are still going to head out for greener pastures though.

> Hopefully this improves the morale of those left and no more layoffs will be necessary.

Well, the dynamic they've introduced most strongly incentivizes competent [read: employable] employees to leave so certainly that will improve overall team performance and they won't need to continue layoffs /s. To call it a death spiral would be excessive, but negative-divergence quality spiral just lacks that special something...

katmannthree··on The C++ Killers (Not You, Rust)
It is done, in a sense, in cases where it really matters (video codecs etc). More tooling for better optimization is cool and exciting and all that, but it's also not free -- extended compilation times in Rust are a nice example.
katmannthree··on The C++ Killers (Not You, Rust)
Beyond that, this article is just a little bit absurd. Say what you will about Rust but it's a functional and gradually maturing ecosystem powering more and more things as time goes by. Given that it's sorta-kinda intended to build the kind of things C++ does, the idea that it'll eventually overtake C++ is at least plausible. In comparison this article claims that

1) A cool research language packaged into a VS Code plugin 2) A cool research compiler for Python + numpy 3) A cool generic ISA project

will kill C++? Maybe for the author's _very_ specific use case of blindly copying things from SymPy, but really I think you'd have better odds betting on a D resurgence.

katmannthree··on Connecticut parents arrested for letting kids walk to Dunkin' Donuts
> for criticizing their government

No. Here's a protip which applies to every country across the globe: if you're donating money to people doing things your government decided is illegal with the express purpose of enabling continued illegal acts, you're gonna have a bad time.

katmannthree··on TSMC is making the best of a bad geopolitical situation
Ahh yes, and that letter is worth taking very seriously because Josh Hawley definitely has no possible ulterior motives regarding limiting aid to Ukraine as a way to help a certain group of people he runs with.
katmannthree··on Globalization is dead and no one is listening
You always will since they're strongly favored in short term outcomes. Think of it as a harm reduction strategy, of the viable options it's generally the least disfavorable.
katmannthree··on The Tesla Semi cab from the practical POV of someone who drives trucks
Not to be patronizing but it sounds like you don't have much experience with work boots or jobs that actually need them. If a driver spends their time going between relatively clean locations then yes, it's a relatively trivial complaint. The problem is that's often not the case: If they have to visit remote, heavy industrial, or some types of farm locations their boots will constantly end up caked in mud, random chemicals, or various biological debris. As someone who has dealt with all of the above, I find the complaint about door placement to be every bit as big a deal as having to get out of the seat at guardhouses.
katmannthree··on Aesthetic PCB Design Tips for Improved Functionality
Pigments can affect the properties and behavior of resins, if you're working with a sloppy fab I could see that causing issues (even if only not accounting for different curing times).

For actual production design like the OOP is talking about, you would likely go with whichever option is cheapest overall (which in my experience has universally been the standard green).

katmannthree··on The world of pipe fittings
If you're talking about quick connects, they'll always leak a bit.

The threaded fittings however are a different story. Assuming you didn't use stainless steel on stainless steel fittings [0]:

* You can find the leaks by spraying soapy water on suspect connections and looking for bubbles (wash off and dry with clean water afterwards unless you want some serious corrosion). You can also buy a jar of noncorrosive propylene glycol based leak check fluid at your local hardware store for somewhere around $10, which is a strictly better option although it's a bit harder to clean off.

* Undo the connection and throw away every fitting you can replace (you generally should not reuse NPT threaded connections unless you know what you're doing). Clean all fittings until they look brand new and with no visible debris on/in the threads.

* Watch some videos [1] and remake the connection using the proper amount of tape and sealant and appropriate torque [2]. Only tighten the fitting. If you loosen it even a bit during the process, undo it completely. Clean both sides, reapply tape and dope, and try again. Let the sealant set ~24h and retest.

[0]: Stainless steel pipe connections are a special case because they tend to cold weld before they're fully tightened. There are ways to mitigate that but the short answer is don't use them if you don't already know how.

[1]: https://www.youtube.com/watch?v=whw9ApDJpJo

[2]: NPT connections really shouldn't be torqued (you instead use turns from hand-tight for properly cut threads) but if you're having trouble find a torque chart for your fitting material (copper, brass, steel, etc) and follow that.

katmannthree··on The world of pipe fittings
The quick connect side yes, the threaded side is a standard NPT (if you're in the US) which you treat the same way you would any other NPT connection.
katmannthree··on Odroid-H3
Generally not all of those. They do come with a case, active cooling, ~~far better graphics performance, and fewer software headaches due to being amd64 instead of aarch64 though~~ nevermind, forgot that this is jasper lake too.
katmannthree··on Intel Core I9-13900K and I5-13600K Review: Raptor Lake Brings More Bite
I'd be curious to see how one measures peak energy density in a modern CPU.

As far as power density goes, the i9-13900K seems to be 335W / (257 mm^2 die area * ~1mm water thickness) ≈ 1.3e9 W/m^3. The power density of the sun in comparison is around 2.8e2 W/m^3, roughly what you'd find at the center of a large pile of compost (although the temperature at the sun's core may be just a wee bit higher).

katmannthree··on Microsoft's AR Headset Was a Complete Disaster During a Military Test
If he just wanted money he would have asked (privately) and he would have gotten it.

Instead he called Putin to talk about "peace" (read: appeasement) and then posts literal Kremlin talking points to Twitter and only mentioned getting money to maintain starlink after getting a ton of people telling him to fuck off.

katmannthree··on Microsoft's AR Headset Was a Complete Disaster During a Military Test
Don't be disingenuous, Elon is getting shit for trying to undermine the actions and goals of the state department.

A charitable interpretation of his actions is that he's occasionally unable to contain his narcissistic traits, a less charitable interpretation is that he's looking for leverage to get his dick out of the hornet's nest that is the Twitter deal, and the least charitable option is that Russia is applying some leverage to force his hand. No matter the reason there's a good chance he'll end up regretting that (to the extent he's able to feel things like regret anyway).

katmannthree··on Intel plans thousands of job cuts in face of PC slowdown
Whether or not they're ``held responsible'' to the degree anyone in such a position in the US is (i.e. lolno), grocery stores and retirement homes do not accept epicaricacy as payment.
katmannthree··on Factory jobs are booming like it’s the 1970s
When your per capita GDP is 2-4x higher than surrounding nations you're looking to draw from it absolutely is.
katmannthree··on Why employees want to work in vilified industries
As it turns out, there's no shortage of goodwill towards the military industrial complex when people feel they're actually making the world a safer and better place.
katmannthree··on Justin Kan: Web3 games don’t need to lure players with profit
Wow, bravo. That is by far the strongest argument against NFTing games I've heard yet. It feels like it should be obvious and yet I've never seen it before.
katmannthree··on Stable Diffusion launch announcement
That was one of the most disappointing parts of DALL-E 2 -- not only is its domain space limited (justifiable IMO) but they then severely limited the outputs and coupled it with a very opaque abuse policy. Their press releases are all "we're gonna revolutionize art" but what they sell is in every way targeted towards the visual equivalent of elevator music.

With DALL-E mini, the classic opening sentence of the dark tower "the man in black fled across the desert, and the gunslinger followed" produces evocative (if abstract) artwork. With DALL-E 2? You get a message that your prompt is inappropriate and your account will be reviewed for termination if you continue. So they don't want guns, okay whatever.

But it eventually impacts pretty much any concept you want to try. I was exploring scifi art and wanted to see what it would do if I tried to get a stylistic fusion of old-school soviet spacecraft aesthetics (exposed structures with bulbous pressure vessels housing the controls [among other things]) with western equivalents. Fusing disparate design philosophies in a way that actually feels creative is a task at which DALL-E 2 occasionally performs superbly and I was really looking forward to playing with the concept -- dreaming through the machine of a long-lost potential future.

Nope! Turns out "Soviet", "USSR", and IIRC now "Russia" are straight up banned words. I burned up quite a few prompts before figuring out that was the trigger.

And then there's the cost. During the closed beta they gave us what's now several hundred dollars a month in access. That translated to less than an hour a day of exploring DALL-E. It felt inadequate when it was free, and now they're asking for hundreds of dollars a month for it? No.

The pricing model makes sense if you're trying to generate bland corporate artwork for some random webpage but as a creative tool it just ensures that the only people really engaging with it have substantial financial backing for producing exclusively milquetoast ``artwork.''

katmannthree··on Ask HN: What's the next big thing that few people are talking about?
> In any case, Dr. Hoffman's theories are mathematically rigorous. I think it's worth listening to the podcast before dismissing.

I can't really comment on that as 1) I only skimmed a couple sections of the paper and 2) my field is more applied math than pure. I'm not attacking or dismissing anything, just asking how the claims made are substantiated.

> However, since it's able to model experiments in the Large Hadron Collider, I would assume that it makes predictions about the positions and velocities of high energy particles.

Do those models cover experiments which have yet to be run, and more importantly are they predictions which differ from those of the standard model?

There are a lot of neat theories which model experimental work we already have results for, the problem is using said theories to make falsifiable predictions which are both realistic in terms of actually finding a way to do experimental verification and are different from predictions made by the standard model. Nobody really loves the state of physics as-is, but moving on to something else requires meeting those two conditions which has been an insurmountable hurdle as of yet.

katmannthree··on Ask HN: What's the next big thing that few people are talking about?
That's a lot of words in those links. What falsifiable predictions does this make?
katmannthree··on Average new car transaction price hits a record $48,043
> Also I think hitting those price levels is unlikely in any case.

Unless we end up with refinery bottlenecks (like we more or less have now) or political incentives (although the odds of that seem alarmingly low at this point).

> The consumption would be lower so price would be too.

Is this expected to hold as oil usage drops over the next century?

katmannthree··on Average new car transaction price hits a record $48,043
Assuming that gas doesn't end up around $15/gal by then...
katmannthree··on Ask HN: What can you realistically manufacture in your garage?
Did they explicitly tell you that's why the order was cancelled? I've placed many personal orders with them and never had issues.
katmannthree··on Google now deleting health clinic searches from location history automatically
This comment shouldn't be at the bottom, they're right. An alternate read of these articles is that Google's building an automated system to identify abortion seekers, and you should ask yourself exactly how much you trust Google now and in the future. There are also other sources of location data which will not be following suit: AT&T's funding is the reason OANN exists at all (Google it if you're not already familiar).

If certain justifications are motivated to prosecute this as some form of murder (which is certainly within the realm of possibility now), Google's location history having holes in it when other data sources indicate that someone's phone traveled to an abortion clinic may not work in their favor. They might be better off perturbing the precise location to something else nearby.

This is basically trying to solve the fugitive state act with technology. Nice idea, but seems to seriously underestimate its adversaries

katmannthree··on Google will remove user location history for abortion clinic visits
Given how cell providers are likewise collecting location data and won't be following suit, it seems like this has a high probability of backfiring...
katmannthree··on Are you a naïve realist?
> Despite evidence to the contrary, nearly one-third of Americans still believe the 2020 presidential election was stolen.

> Speaking of naïve realism, what evidence

You can really only prove this type of thing in a single direction, by providing evidence that there was fraud on such a scale as to have swung the results. Otherwise, one could endlessly claim that the election thieves just covered their tracks so well that you don't have any evidence of your assertions regarding their behavior.

The burden of proof was on the ones making accusations of election stealing, and as was reflected in how they lost case after case regarding this, _they did not provide it_.

katmannthree··on Cheap, green hydrogen would be a breakthrough in clean energy
The turbine blades are downstream of the combustion chamber so they handle combustion products not hydrogen-rich gas. The turbine combustion chambers, fuel handling system, and high pressure H2 compressors[0] _do_ have to function in a high pressure high temperature H2-rich environment.

0: Take a guess as to what those look like inside.
