Summary:

> Rather than allowing heat to build up, what if we could spread it out right from the start, inside the chip?... To do that, we’d have to introduce a highly thermally conductive material inside the IC, mere nanometers from the transistors, without messing up any of their very precise and sensitive properties. Enter an unexpected material—diamond.

> ... my research group at Stanford University has managed what seemed impossible. We can now grow a form of diamond suitable for spreading heat, directly atop semiconductor devices at low enough temperatures that even the most delicate interconnects inside advanced chips will survive... Our diamonds are a polycrystalline coating no more than a couple of micrometers thick.

> The potential benefits could be huge. In some of our earliest gallium-nitride radio-frequency transistors, the addition of diamond dropped the device temperature by more than 50 °C.

> Is starship on schedule?

Difficult to say relative to current Artemis timelines, which have to date been mainly delayed by Orion. They're currently looking on schedule to perform an orbital propellant transfer in 2026. That likely means a commercial launch before the end of next year, which is crazy.

How that relates to HLS is up in the air, and probably will be until the end of next year.

"Not within the next decade" (e.g. not until 2041) is a long time.

The first prototype of Starship only did its first hop in July 2019, so 6 years ago. The first flight integrated test only happened 2,5 years ago.

Nowadays they can return to Earth already and catch the booster. Why would you expect the rest of the development to drag until 2041?

I used to recommend KDE-Connect left and right but stopped doing so because it went from rock solid and dependable to a complete disaster in a couple of years.

Linux, Android, iOS, macOS all worked in harmony. Now not even two Android phones using the same software version can see each other, file transfers keep failing after a brief while. And all with the same devices that worked before, across various networks.

Not to say anything about connectivity between Linux and Android or iOS.

I have dreams of porting the old Strategic Commander game to newer devices. Someday I hope it rises to the top of my todo list. I logged hundreds of hours on that game playing with my friends and brother.

Taking turns via IR blaster or pass-and-play was amazing in an era without wifi or cellular data. No account signups or anything, just point your devices at each other and you had a game going. And without continuous connectivity, asynchronous play was the default way games worked, so it worked great.

How is it relevant that they are biased? Most opinion focused journalism is "biased" in some way and will tell you that you should be voting a certain way. They will even try to make arguments why people with different preferences should vote for the journalists preferred party, that is a normal part of opinion journalism. How is that substantially different than asking an LLM and it giving you a certain opinion.

What answer should an LLM even give? Just none at all?

> You could buy three for the price of a Tesla.

Except you could actually buy a Tesla today, which is not something you can do for a Slate. Also they don't even have expected delivery dates or official pricing yet, so who knows when they will be available or what the actual price will be.

I would love for Slate to become a thing, but at this point it looks like vaporware.

Some entire industries have this problem, eg trucking. There is this shortage of truck drivers. The quiet part is that it's at the rates trucking companies are willing to pay. That rate is based on what they can charge to customers plus a thin profit margin. Because trucking is too easy to get into, companies can't simply raise their rates because other companies will undercut them (in their own desperate bid to survive). This kind of market competition is healthy for the "market", perhaps not healthy for workers.

The depletion of tech workers for Amazon is similar. The part that isn't said is: at the salaries Amazon is willing to pay. Amazon has a different market to worry about, the stock market. They can't just increase their HR spend 25% without taking a hit in the stock market. And I guess they aren't willing to change the work environment to be more attractive. Maybe they can't at their size, as it can be hard to avoid dead weight.

Google doesn't hire in the US for some PAs, for similar reason. Salaries are capped (artificially) by stock market demands. But Google doesn't call it worker depletion.

It doesn't matter. Most jobs even at those companies were not in the interesting areas you heard about. For every one person at the cool jobs there were thousands elsewhere who had regular deadlines and a regular job. Odds are you wouldn't have had the cool job even if you were born in the right era.

Better advice: when interviewing ask questions when they ask if you have any! Find out what the job is really like.

Ask what hours they normally work - if they give exact times that means they are strict about the times. If they give a lot of hours that means you are expected to work a lot of hours. If they give a range that means they really have flexible times. If they talk about leaving early for their kids third grade events that means they support families.

Ask what they really wear - this is clue to what the dress code is like.

Ask about the perks you care about. I don't play ping-pong so won't mention that perk if I'm interviewing you, but if you ask I can tell you that there are regular tournaments and people do play games here and there, but the tables are empty in the middle of the afternoon: if you care about this perk ask, otherwise focus questions elsewhere.

There are a lot of great jobs. There are a lot of bad jobs. There are jobs that you would hate for reasons that the people who work there don't even care about. There are jobs you will think are great that others will hate.

I don't want that kind of flicker, though. I just want the image to look good:

> I want a deinterlacer that can figure out how to make the (cough) best image possible so deinterlacing artifacts aren't noticeable.

You're both right.

Used to be, almost everyone learned to play an instrument. Families would play together around the fire, or children who excelled would be invited to perform to entertain at their parents' party.

Sheet music was the "Top 40" of the pre-Edison days, and people made good livings writing it.

OTOH, mixes and remixes, greatly spurred by innovations in rap, have proliferated in the last 30 years. But that's not the same pervasive skill set in society.

> You could have just said you didn't read the John Eastman memo

Show me where exactly in the Eastman memo, the so called "coup plot", it calls for a group of protesters to go into the Capitol?

Spoiler: It doesn't. So it's actually you who hasn't read the memos. If anything, it shows Trump sought to remain president by legal means, a gray area at worst, but nothing to do with the "violent insurrection" claimed.

You mean the cases that were thrown out by the courts? And another that he closed himself? In other words, they had 4 years and found nothing. You are innocent until proven guilty, and ultimately he proved nothing.

Because it's about, and always has been about, and always will be about, power and personal connection, not following the rules. Following the rules is one avenue to power - if the rules are enforced as written. But there are others, like bribing whoever is meant to enforce the rules and then breaking them. Another is to abuse rules, like setting up a string of companies that go bankrupt like crumple zones.

Pretty much. Starship is a source of delays - but not the source of delays. Even if Starship HLS was ready to go yesterday, I would still expect Artemis 3 to schedule slip all the way to ~2030.

Getting everyone involved in Artemis to deliver on time, let alone on budget, would require nothing short of divine intervention.

The first claim isn't true, because Elon has been a bitcoiner for a long time. There was a huge Bitcoin hype / hubris at that time. Specifically, Saylor happened, and he convinced Elon and others that Bitcoin is the best reserve asset, and Tesla had a lot of cash, which was melting like an ice cube due to inflation. There was a lot of inflation talk / protecting against inflation. And in the end it actually worked out for them pretty well, given that BTC has about tripled since then (they bough at $34k).

After they had bought the bitcoin, adding it as a payment option was a way to add hype to increase its value. They quickly found out that it's too volatile for payments to be practical, and the hype cycle was ending anyway and they sold half of their reserve.

It surely does not make sense to screen the entire population for pancreatic cancer, but we already do have a screening for pancreatic cancer in Czechia for "at risk population".

For such programs, a blood test would be a huge boon and they could even expand the coverage a bit.

I had a very similar experience with an amazon interviewer over an even dumber reason: I was going on vacation. Seems dumb, but in your early 20's, with everything booked, I was excited, and frankly didnt see why it was worth insulting me (Its pretty normal to be too busy to do a first round interview on a given week, sometimes things get pushed back 7 days.)
Show HN: Ghswap – CLI tool for managing multiple GitHub accounts
by shubham213 | 2025-10-21 14:02:14+00:00
Managing multiple GitHub accounts (work/personal) is a pain – switching git configs, SSH keys, and GitHub CLI auth manually.

I built ghswap to automate this. One command (`ghswap work`) and everything switches. It also supports directory-based auto-switching and handles SSH key generation.

Install: npm install -g ghswap Repo: https://github.com/shubhamV123/ghswap

Would love feedback from the community!

On the other hand, I paid $41k for a 2024 all wheel drive 3 row (5 adults + 2 kids) Model Y. That saved me $20k+ compared to alternatives.

> 3d camera view

The illustrated overhead view is sufficient that I do not miss a 3D camera view.

>The ability to exit your vehicle if there's a power system failure

This is not true, at least in my 2024 Model Y.

Not having carplay/android auto sucks, but I haven’t missed it enough. And there are enough tactile controls, in my model at least, that it hasn’t been an issue.

All in all, I wouldn’t pay $60k for a Tesla, but sign me up @ $41k.

I find this article quite poorly constructed. It does not even give a statement about the reasoning behind why Karpathy said getting to https://ai-2027.com is unlikely. It also does not clearly define what AI 2027 is?

The following paragraph is almost complete gibberish:

"For AI experts, Karpathy's view is a better counterargument to short timelines than ours. But for non-AI-experts, we think the practical considerations we raised are worth reflecting on with 6 more months of evidence. As forecasters, this is more of an "outside view" - regardless of how exactly AI improves, what problems might slow down an R&D-based takeoff scenario?"

Why would Karpathy's view be different for AI and non-AI-experts?

Did they use AI to write the article?

> AI tries to describe the options there goes all faint hopes for "unbiasedness"

Is it bias, though, if the AI is trained on the materials of the parties involved, rather than that of public opinion?

A fellow I know has built exactly this, specifically for analysing the various Dutch political parties positions on things, their polices, constitutional stance, and so on:

https://kieschat.nl

So maybe what this story is really about, is old-school-media being terrified of losing eyeballs to a new generation of voters who, rather than listen to the wisdom of the journalistic elite, would rather just grep for details on their own dime, and work things out vis a vis who gets the power and who doesn't ...

If AI gives people a chance to actually understand the political system, like as in actually and properly, then I can see why legacy media would be gunning for it.

People get the cause and effect of fancy EVs backwards.

To build an EV you have to spend $10-$20k on the battery pack that goes into it. They're getting cheaper, but that is a gradual process.

So your Toyota Camry / Honda Accord EV competitor is going to need to be priced starting at $40k to have a chance of breaking even.

How do you get people to stomach $40k for a base Honda Accord but Electric? You add things that cost very little but make the car feel more premium. Power seats, big screens, LED interior lights, glass roof, a processor that can play video games, cameras and autonomy features, etc. don't cost that much in the big scheme of things. Some of them, like screens instead of physical controls, might even save money in production and assembly costs.

So you add ~$3k worth of "premium" features to the car, price it at $45k, and now the buyer feels like they are getting something worth the money.

The article and paper don't mention it, but the thermal conductivity of single crystal diamond can be increased another 50% at room temperature by using pure carbon-12. The isotopic uniformity reduces scattering of phonons, which are what transports heat energy in diamond. For a very thin film like this the cost of using isotopically purified carbon shouldn't be that bad.

BTW, the thermal conductivity of C-12 diamond at cryogenic temperature is even higher, reaching something like 41000 W/m K at 104 K.

Isotopically purified silicon has also been considered due to its higher thermal conductivity, but the effect there at room temperature is not nearly as dramatic.

Weirdly, I read UV damage in C-12 diamond is reduced by a factor of 10 vs. natural diamond, I understand because this damage process is mediated by phonons. No relevance to the chip use case (unless UV damage in photolithography could be important?), but I found it interesting.

Thank you!

> Did you benchmark against other Go web servers like Caddy or fasthttp?

I have already benchmarked Ferron against Caddy! :)

> so I’d love to hear more about how your server handles concurrency or large responses.

Under the hood, Ferron uses Monoio asynchronous runtime.

From Monoio's GitHub repository (https://github.com/bytedance/monoio):

> Moreover, Monoio is designed with a thread-per-core model in mind. Users do not need to worry about tasks being Send or Sync, as thread local storage can be used safely. In other words, the data does not escape the thread on await points, unlike on work-stealing runtimes such as Tokio. > For example, if we were to write a load balancer like NGINX, we would write it in a thread-per-core way. The thread local data does not need to be shared between threads, so the Sync and Send do not need to be implemented in the first place.

Ferron uses an event-driven concurrency model (provided by Monoio), with multiple threads being spread across CPU cores.

Absolutely.

There's a funny but very crude saying in Slovakia, which where he's from so he might know it, lol. I cannot write it here for obvious reasons but it's related to letting people do things to you for money ...

As others have pointed out, there were a lot of incentives ($$$) for Krapathy to behave like that during his tenure at Tesla.

A Forth-like command-line shell (bash replacement) does sound quite interesting actually, particularly if the stack is displayed on the side and is not implicit.

It's rather concise, most functions tend to be a single short line. Its syntax is minimal (or non-existent according to some), it's just flat white-space separated tokens. It has imperative/interactive semantics, in the sense that every successive word makes some changes on the current state (the stack).

All of this makes it quite amenable to be used as an OS shell I think, it seems obvious in retrospect.

The idea of starting with an empty Forth and creating a whole universe of automations and DSLs for your system, one command at a time, is quite pleasing, in a purist sense, although perhaps not entirely practical.

Does such a shell exist? Not as minimal as Ilo, one you can actually use in a modern system instead of bash and the like, ideally with a nice display of the stack. Probably Factor is the most appropriate Forth-like to build it on, it already has a good REPL mode, it would mainly involve adding a bunch of utilities for practical command-line use.

That would completely change the situation, so yes.

The thing is that diplomas matter only in very few sectors. Like medicine, law, physics and such. But in tech, realistically, the value of a diploma is 0.

Again, focus on a popular language, do some projects with it(so you have something to showcase) and after you get hired you can start specialising on specific things. Like web services, 3D engines, database and whatever else you'd want or need.

In short, you have to be smart about transitioning from academia into the "real world". As you have a diploma and you have been teaching, it means you are likely in your 30s, which is great, because id you would be Gen-Z or Gen-A, you'd have much harder time getting hired. So you are not position all too bad.

It's a shame they don't include any details about how this was tested, so it's impossible to know how much of the results were actual bias vs. the Dutch watchdog's inability to use them. I wouldn't be shocked if their prompts were along the lines of "I'm a liberal - who should I vote for?"

In practice, AI ought to be really helpful in making election choices. Every major election, I get a ballot with a bunch of down-ballot races whose candidates I know nothing about. I either skip them or vote along party lines, neither of which is optimal for democracy. An AI assistant that has detailed knowledge of my policy preferences should be able to do a good job breaking down the candidates/propositions along the lines that I care about and making recommendations that are specific to me.

"You are arguing for testing everyone there."

Are you mistaking me for someone else? I never said or even implied that.

"And a 99% overall false positive rate is easy to achieve,"

Not in the real world, any such experiment will be shut down long before the asymptotic behavior kicks in. Real healthcare does not have unlimited resources to play such games. That is why I don't want to wargame them, it is "Luxembourg attacks the US scenario".

"There are no specific risk groups for pancreatic cancer"

This is just incorrect, people with chronic pancreatitis have massively increased risk of developing pancreatic cancer (16x IIRC). There also seems to be a hereditary factor.

Czech healthcare system, in fact, has a limited pancreatic cancer screening program since 2024, for people who were identified as high-risk.

ChatGPT is not a platform for developers. You are using the wrong tool.

And you are using it incorrectly even if it were the right tool. If you have a trivial function to write that should be 10 lines of code, why are you having AI do it in the first place? Just code it. Or, if you really want AI to do that for you and must have a short simple function, say so in your prompt - it will comply.

I'm not well versed in qemu's various options. When I didn't specify a BIOS image, it seems to be using SeaBIOS, not UEFI, and hangs on "Booting from Hard Disk...". I should be able to start doing proper videos soon; I've been slowly working towards that.

I can say that the display & overall performance is noticeably faster on the two actual computers I tested on than under qemu on my Linux system.

I've written a format specification paper for .faf (AI project context format) and need an arXiv endorser for cs.AI or cs.SE category.

Background: - Built .faf to solve 0-55% AI context completeness problem - Official Anthropic MCP integration (PR #2759) - 8,800+ npm downloads, 800+ weekly users - Cross-platform validated (Claude 9.5/10, Codex 9/10, Gemini 9.5/10) - IANA media type registration submitted - IETF Internet-Draft ready

The paper documents the format specification, validation methodology, and production deployment metrics (10-13 pages).

First-time arXiv submitter, so I need endorsement from someone with publication history in cs.AI or cs.SE.

Does anyone here: - Have arXiv endorsement capability in these categories? - Know someone who might be interested in reviewing? - Have suggestions for finding endorsers?

The format is open source (MIT), production-deployed, and addresses real infrastructure gaps in AI-assisted development.

Paper available upon request. GitHub: https://github.com/Wolfe-Jam/faf

Any help or pointers appreciated!
