Imagine you have dreamed of some new discovery your whole life. Let's say you are convinced that, I don't know, there exists in the world a naturally bright pink species of cat. You study cats; you know their behaviors, and can guess at the means of finding this elusive pink jungle cat. You search for years to no avail... when suddenly, without prior warning you are on vacation in some remote island and hear a rumor. This pink cat you've searched for is known to the locals, and they can tell you exactly how to find them. You follow the guidance and sure enough -- there they are! The legends are true! You're shaking with excitement and want to document this finding for other pink cat researchers, but you don't have any professional equipment. Just your phone... but any evidence is better than nothing, right??

TL;DR: You are not the intended audience for these videos. They're not trying to convince you -- it's meant for other researchers. We are just seeing the leaks.
I have answered to another poster in a bit more detail, but a conservative estimate with moderate to a few moments of heavy usage is ~9 hours. I have done 11+ on pure-coding stints (no video, no games).
Most Nobel winners get their prizes during their 60s-70s. It means that people who graduated in the 1970s are just starting to get their Nobels.

And the trend of aging winners continues as research become more complex and specialized and therefore requires more experience. The time between theory and the practical discovery (Nobel prizes are only for the latter) increase as experiments become more complex too. So much that it may become difficult for theorists to get a Nobel in their lifetime. That LK99 thing, if real, is more the exception than the rule.

Why do you think it's an S-shape? As you say, we're heading for a singularity!
Although it's a single API, the application event tracing doesn't seem to have much in common with the kernel event tracing. I got the impression that they were separate projects, someone made the decision to jam them together, and it's just a mess. But I have no inside knowledge.
> When I was a kid I tried to build a windows app. Getting a notepad clone even kind of close was a triumph for me,

I remember having similar struggles. Windows programming was a huge lift. Not only were there new API's to learn, it was really an entirely different and novel architectural style.

Kerry Nietz writes about the experience of porting FoxPro from DOS to Windows... his description is apt: "Turn the program inside-out". For me, that was hard to do at a time when I was still working through how to make a normal program.
It is actually used and it exists. https://en.wikipedia.org/wiki/Superconducting_magnetic_energ... See applications
Yeah, good point. I wrote them as ``` ``` blocks in markdown, and it doesn't wrap apparently. Will look into if I can tell Jekyll to do something there (would not prefer to escape everything hard-coded to 80 lines or some-such).

Update: Ha! I got this working. I added a "code { white-space: pre-wrap !important;}" css line in the <style> section of my custom html header. Seems to look much better.
I’m sure tipping will be next.
I wasn't aware there was a difference, I mainly just remember the copy of the book I had all those years ago and incorrectly assumed all the content was ported from the original.

Maybe you could cheat: there are a fair few emulators of that era of machines that you can SSH into, drop the code into one of those and run as originally intended! Or access via the web by hooking shellinabox up to connect to the emulator's console. You'd need to add some layer of authentication if making this available on the public internet for friends to access though. Might be easier to setup than actually porting that old “minified” code (with single-character variable names, GOTO-a-plenty, & minimal comments) and implementing something to manage multi-user access to the same game instance.
Oh definitely, there's a reason my home GPU is an AMD! The fact that driver troubles are (sort of) a thing of the past is a great win.
I thin it's important to think about the context of "machine time". If "machine time" is some computer somewhere that only runs your code, then sure. Even as a customer, it might be cheaper to just pay more for a beefier machine than to pay more for optimizing the software.

But when you're building human user-facing apps, you can't always just get a faster computer. As others have said, many instances of lag in windows can be traced to network calls. A 64-core monster would probably wait around just as long as my ultra-low voltage, several year-old lazy ultrabook.
We'll have only part of that because this is lead based. Lead free regulation is the law of the land in many places and it's getting tighter. We spent decades finding out how absolutely harmful lead is to humans.

Only the industrial sector could claim exceptions but would still need to comply with safe cleanup and disposal.
As if the US is the only country. Plenty of EU countries, China, and Japan would invest in developing even higher speed rail options.
GGA-DFT (+ some corrections) used here seems quite ok to me for this system. For more trust into this, I would like similar calculations with other methods to see how similar or different they are. LDA-DFT will most likely not be great (as in most cases), but I would be very interested in some DFT+GW calculations, even though LK99 might not be it's strength.
I'm not an expert on chemistry but it sounds like this would make it ridiculously hard to obtain a high quality sample. Copper can substitute for either lead site; I'm not aware of macroscopic processes that would favor one over the other. Problems like that are usually handled ad hoc. The authors seem to have bumped and shuffled their way there through the darkness.

For context, the preparation of tetrataenite was pursued for decades (first partial success October 2022) even though the structure was well-known and the constituents are just nickel and iron.
4090s have 24GB of 384-bit-wide GDDR6 with no ability to interconnect that memory to other 4090s except thru PCIe bandwidth.

H100s have 80GB of 5120-bit HBM with SXM NVLink for 8-at-a-time in a rack.

HUGE difference in bandwidth when doing anything where the inferring the model needs to be spread over multiple GPUs, which all LLM's are. And even more of a difference when training is in play.
Licensed captains with Master of Towing endorsement are currently getting $800-$1,200 per day in regions I am familiar with.
The irony may be that removing the barrier to legal advice in that way will at the same time make the implementation of your startup a triviality.
I have absolutely zero clue on materials science, chemistry or physics of this experiment. Can anyone explain to me why some teams are able to replicate it while others can't?
It is pretty obvious that most people who comment here are not aware that while superconductivity implies diamagnetism, diamagnetism does not imply superconductivity.

This is not mentioned at the linked tweet, so I believe that it was necessary to remind everybody of this, to avoid misunderstandings about the meaning of the "successful replication", which for now only proves strong diamagnetism, supposing that no errors have been made.

Even if LK-99 were only a strongly diamagnetic material, without being a superconductor, that would still be a very interesting and useful discovery.
The tool looks great; I have a hurdle to overcome with the name.

I'm long accustomed to spelling it, in English, as Jujitsu. I've also seen Jiu-jitsu. "jutsu" is much less common, IME.

Is there such thing as canonical Romanisation of Nipponese? I can deal with a project being "wrong" better than not knowing which of us is wrong.
Or you could avoid building the machinery and just pump water up and down. Then to lower the cost you could drop the tower idea and use a natural hill with reservoir on top. Surprise, surprise you just invented a pumped-storage power station.

First Rust Digger report: More than 80% of the crates link to their public VCS
In the Rust Digger project we collect data from crates, at this point it is only the meta-data from crates.io, but we plan to include data from the GitHub repositories.

However, this data is already useful for some minor contributions to Rust crates. Specifically, crates that have a link to their VCS are going to be easier to find if someone wants to contribute to them.

So we created a report listing all the crates that do NOT have such a link. See the first report.
The OLED version had the stick drift too, I had to return it.

consider that a big part of why we cant make better processors is because they get hot, and they get hot because of resistance. I'd say dramatically faster chips in smaller form factors (think enormous graphics card in your phone, most of the bulk in those is cooling) would be quite a revolution !
Pretty shocking their managers let them get away with this. At least that’s stopped now.
And while you or I might be willing to put up with that as we're aware of the person and circumstances, there are many more people who don't know who he is and his circumstances and merely see the profanity-laden ramblings, and will simply leave. Keeping Terry on HN was untenable.
So we need a bridge constructor 2, already exists. In reality its Excel, the game.
At the maximum it is a superconductor obviously
Markets are fundamentally about choice and trade offs. Monopoly is about runaway power dynamics created through random chance and force (you have to pay rent, you can’t choose not too).
How to train your custom SmartTool for semantic segmentation task on agricultural data
That's certainly a way, especially that reinstall takes about as much as full upgrade.

But I use configuration management anyway to keep the machines consistent, and, well, upgrade is less work than reinstall... especially if talking hardware that can take 5+ minutes just to reboot (which is like every actual enterprise server I saw).
my initial reaction, half OT:

Ooof, random "ASCII" (actually: Unicode) art & dev-chosen colors, my bane of the "modern" CLI applications. That drawing you like? Doesn't work for me, give me the raw output please. Those colors you love? Aside of red-green weakness being the most dominant factor, what you're really doing is trying to set things apart, connotating color with semantics as well. It's nice this works fine on your white-on-black terminal. Have you tried this on a white-on-firebrick terminal? Yellow-on-green? Or anything else than _your_ "normative" setup? Man ...

Also not sure the information presented is adequate. E.g. consider commit 76(2941318ee1) - jj makes it look like that was committed to that repository, while it was done to another. The git presentation looks more spot-on (for that particular commit, while the rest of the display is just a mess - ASCII art that does not add semantics, random colors); also where is 1e7d displayed in jj's output? Why is jj's order different? I remain unimpressed by both UIs.

" Create a file at ~/.jjconfig.toml" ... $XDG_CONFIG_HOME ?

When is that working copy committed? When I run jj? Why bother, when it's not working asynchronously and automatically? And if you commit working copies, do you sync under the hood with stuff the other folks you collaborate with? If not, why bother?

Oh nice, a command to fix "stale" workspaces.. how about you don't let workspaces go stale?

This may all seem to make sense to git-minded people, given the comments here. To me, neither jj nor git make sense (as fossil-minded person who has to work with git), so shrug enjoy....

..but please fix that ASCII Art and Color Stuff, thank you very much.
I know this isn't typical HN type news, but to me this feels like the true beginning of the end for physical media.

I have always loved having the physical movies in the best quality that I can receive, VHS, laserdisc, DVD, Blu-ray, and these days 4K blue rays.

I still stand that watching a movie in 4K from the UHD disc appears better quality than what I see on streaming.

And at the end of the day, if the streaming service decides to pull the movie, I still own a physical copy of it. I have so many laserdiscs and DVDs that just aren't available anywhere.
I didn’t install the plug-in, but made a mental substitution and reread the thread. Now I am chuckling like a grade schooler over some madlibs and dribbled coffee down my shirt.
That's pretty fantastic!

When will this be available in Idea?
And they have no dependencies? Despite being known for being hellish to install due to how badly they handle dependencies…
Because successful games aren't about copy and pasting as many pre-made assets and code together and shipping it. You can certainly do that nowadays for the Unreal and Unity engines but eh.

They are all tailored experiences to form what is known as the game.
Yes. I've used both and WMI is worse than ETW. The article about ETW made me laugh. Your comment reminding me of WMI made me feel slightly ill.
To prove that point, shouldn't they cut the material in half ? and keep only the levitating part ? Why haven't they done so ?
Thanks, it makes sense. I don't understand why this was downvoted.
This is just as true without systemd. Auto-restarting services without monitoring will always hide problems, regardless of what’s doing the restarting.

This is just another reason to track and alert on error rates.

It also depends how sensitive you are to failures, and required availability.

But in general this sounds more like: “you need observability on error rate”, more than anything else, and that includes notification and alerting on set thresholds that seem aberrant.
That won't work for local changes to files that are legitimately committed in the repo. Like if you need to set your local database, or your own dev hostname in config, for example.
Probably yes for both questions. Ch.4 of Hacker's Delight starts with assuming all quantities are signed integers. A little further along, a lemma about computing b-a when a≤b is introduced:

Lemma. If a and b are signed integers and a≤b, then the computed value b-a correctly represents the arithmetic value b-a, if the computed value is interpreted as unsigned

It's been a while since I worked through any of Hacker's Delight, but I think this means that unsigned values can be used to check bounds of signed and unsigned values. This post is an improvement over that work, so this same property should hold for these new bit-twiddling equations. Still, I'd run a few test to make sure.
> The Visual Studio 6 box had an introduction book to win32 and MFC ... Nothing made sense to me, a lot of boiler plate code was there without much explanation about why it was there.

Some of this is a symptom of the fact that Microsoft was still fumbling in the darkness regarding its Windows developer experience.

First generation windows programming was a complicated affair involving a number of command line tools, textual languages, and switching back and forth from the GUI to DOS. The first Visual BASIC product fixed all of that, and made it possible to achieve good results with just point and click and (more or less) scripting code.

My read on Visual C++ (predecessor to Visual Studio) was that Microsoft was pushing hard to graft the Visual BASIC style of point and click development onto its old school Windows development tools. The result was an IDE with a form editor that could superficially work a lot like Visual BASIC. You could drag a button, double click it, and be dropped into a blank C++ (rather than BASIC) function to handle the click event at runtime.

They did this with specific features in MFC, but also with a huge amount of default code generation. Double clicking that button in the form designer would update message maps, write a function, and make a number of other changes in the source text of what was already a large body of generated code.

The trouble is that while this worked, it didn't actually teach people what was going on. The development environment wound up being very brittle and hard to understand, particularly if you did anything that confused the IDE integration.

On that note, I’d like to see a paper about the failed replication attempts especially from the Indian lab that ended up with a paramagnetic insulator. Not that I’d understand anything, but a comparison of various attempts might lead us to the understanding of what works and what doesn’t.
I most definitely agree. To be honest I know I go against the current here, but so far there is nothing I really like from what I’ve seen in jj.
I should try it for real, see how it feels when using it to get a better sense of it.
All of a sudden it seems the commenters have started name-calling and stereotyping the poster (realjhol) without any evidence or links to dispute his statements. Maybe replying in good faith would be a more helpful discussion, with links to support/deny his arguments?

Your approach of the problem, while theoretically correct (world is infinitely complex, therefore no model can encompass it, news at 11), is of zero practical use.

As a matter of fact, IIRC, the Chinese around the 11th century walked the exact same intellectual path, which led them to conclude that trying to model the behavior of the natural world was a waste of time, and made them completely abandon the idea of simplified, yet predictive and therefore useful models.

The net result was: they killed their then budding tech/science endeavors in the egg.

In other words, your take does not seem to be particularly fruitful.
Sounds like a logical step forward from current debuggers!
I had some colleagues who bragged of not needing debuggers for their workflow... Well, sometimes I really do.
The code the unexperienced write is infinitely faster than the non-code that would be not-written by nobody would the unexperienced not write code.
VRAM speed is a major factor. Even ddr5 with 4 channels would be slow compared to current GDDRs.
I mean, I don't see why I should work around legacy limitations of 1970s software today, whenever I use a computer. Otherwise we might as well decide that file names should have no capitalization and be eight characters long, or that paths should be limited to 127 characters, etc.

Similar moment was in Africa in 1960, after they got AK45 and other cheap weapons. It was easy to dominate Congo River Basin with a few Maxim machine guns mounted on boats, when opponents had only spears. But when every tiny village gets comparable fire power, there are no colonies!

Not because of JS in any case. JS is the whipping boy of desktop performance because its ascendance happened at the same time as what you say: interfaces that update on the fly and need data from the net to do anything at all.

So now download times get blamed on JS and Electron by the haters. Ah, well.
Well that is not really what the article is about. It's more about the problem of induction itself, and the problems of its use as basis for both Science and Philosophical endeavors. The article only made a flimsy drive into the subject, and the Wikipedia article does a much better job.

"Problem of induction" - https://en.wikipedia.org/wiki/Problem_of_induction

"...First formulated by David Hume, the problem of induction questions our reasons for believing that the future will resemble the past, or more broadly it questions predictions about unobserved things based on previous observations. This inference from the observed to the unobserved is known as "inductive inferences", and Hume, while acknowledging that everyone does and must make such inferences, argued that there is no non-circular way to justify them, thereby undermining one of the Enlightenment pillars of rationality..."

Because exponentials will eventually break the laws of physics.

For instance there is a relationship between information and energy, so a system processing an exponential amount of information will need an exponential amount of energy, which the universe will eventually run out of.
