And that's a bad thing?

A country's government sees an opportunity to invest into a promising new technology that could reap tremendous economic benefits. Such benefits include new jobs, new income, the ability to increase social/political capital worldwide, and help usher in a world that is that much less reliant on oil.

That's what countries in the first world are supposed to do.

OK, this is something I know very little about so you may have to explain it like I'm a complete noob, but I still don't understand why, if all you want to do is boot 64-bit Linux, you couldn't use, say, a Raspberry Pi 4 instead of spending thousands of zloties on an 80-core machine that requires industrial cooling.

Lightly altered using artificial intelligence to obscure the original writer:

I used to work at Palantir, and this article strikes me as reasonably balanced. The key question, as I see it, is "what other options do we have?" This applies both narrowly (alternatives to Palantir specifically) and broadly (alternatives to upgrading our government's technological capabilities).

On the broader point, I doubt Americans will tolerate a technologically backward government much longer. The extraordinary latitude given to DOGE reflects mounting frustration with fundamental governmental inefficiency (which various bad actors are certainly exploiting). Citizens won't stand for a government that stays technologically frozen while everything else rapidly advances.

Therefore, we must modernize government. While I don't think our current circumstances constituted the kind of crisis that might warrant DOGE's reckless approach, sufficient neglect would eventually create exactly that crisis.

This brings us to the narrower question: how do we actually accomplish this? The concerns being raised are undeniably legitimate. We (as Americans) shouldn't construct a surveillance state, not even under a benevolent administration and certainly not under this one.

From my perspective, Palantir represents the best path forward due to the relative imbalance between positive and negative potential outcomes. Nothing makes Palantir uniquely suited for malicious purposes in this scenario. The real barriers are cultural, legal, and institutional rather than technological. Anyone could combine large datasets and perform the same analytical work that Palantir facilitates using countless commercial or open-source alternatives.

However, if you want to harness modern technology's benefits while avoiding its dangers, Palantir offers unique advantages. Creating comprehensive unified datasets within Palantir would provide significantly more mechanisms and controls for managing their application than any other platform.

I simply don't believe that deliberately limiting our government's technological infrastructure is a workable approach to protecting Americans. Laws will be regrettably our only real protection over time, and Palantir's platform is uniquely suited to "encode" those laws into software to guarantee compliance but we need those laws and functioning institutions to enforce them.

American expat living in Thailand reporting in. I think the cheapest car in Thailand is the 2025 Suzuki Celerio which is a 5 seater hatchback. At the current exchange rate it's $9,800 brand new. Of course this figure is not adjusted for purchasing power (so what?). We have BYDs here and I haven't really looked at them but pretty sure a few are under $25K.

If Americans can't get a new car for under $25,000 but Southeast Asia can get them for under $10K, something is wrong. If the entry level car is 2.5x more expensive in America it means Americans are getting fleeced. I haven't lived in America for a long time and I feel like this makes it very obvious to me when the BS machine over there is in full spew. Free markets drive consumer prices down to the cost of production.

I don't know the auto industry in detail but it is an extensively documented fact that America has few free markets left, and they've been replaced by cartels - each industry has a couple of crooks at the top who rotate between private and public jobs. On the public side they come up with excuses to not enforce the anti-trust laws that are on the books, and they add regulations that raise the cost of business. On the private side they come up with ways to improve margins which usually involve fucking consumers.

Let's not make excuses for the criminals. America needs free markets and cheaper cars. Elite lawlessness is the cause of increased costs in America.

Not disagreeing, just elaborating, about “fine” Chinese Amazon tools.

I needed safety wire pliers to assemble some brake rotors. The metal in the ones I got on Amazon was softer than the metal wire they came with such that the cutting edges got little wire-sized dents in them and increasingly useless the farther I got along in the job.

Returned those afterward. Junk.

But there’s other stuff I’ve gotten from RANDOMLETTERS Amazon that’s actually holding up “ok.”

Also, Harbor Freight is a better source of ok/fine tools where you don’t need quotes around those words.

I don't understand the sibling posts that're arguing with you.

Consumer-grade containers would be cheaper than 3d printing if buying a set, it'd get folk up-and-running without fuss, and when they wanted to customize it they could do so with the help of any of their 3d printing fanatic buddies.

So yeah. I agree with @stephenpetryk. Storage solution companies should start marking their bins as Gridfinity-compatible (which is a protected use of copyright regardless of whether "Gridfinity" is copyrighted).

This article fits HN guidelines well - it covers a significant tech industry development that would interest hackers (Meta's aggressive AI talent acquisition strategy with $100M packages). It's from a reputable original source (The Guardian), uses the a title without clickbait or editorializing, and discusses substantive tech/startup content that gratifies intellectual curiosity about AI competition and talent dynamics in Silicon Valley.

I do a lot of work on my own vehicles. I think a lot of the responses are from people who do not.

Paying for vehicle repair labor is basically a tax. They're making it harder and harder to fix your own car. I spent the afternoon yesterday trying to find headlight assemblies that didn't need to be coded to work correctly. Headlights.

All the outrage about right-to-repair around here, and nobody realizes the frog is almost boiled around repairing cars.

Person A: "Learning X is a poor use of time for almost everyone. Here are some numbers."

Person B: "And yet some people learn X! And X is superficially similar to Y, which tons of people do with much less time investment for much more money! Checkmate!"

I have no idea what your actual argument here is. This follow up isn't doing any favors.

---

My experience is that you reach "fluency" in your first programming language in about an order of magnitude less time than you can any human language. Python took me about a summer of teenage study at about 2 hours a day to feel comfortable with. Most further programming languages took an order of magnitude time less than that.

Human languages by contrast demand no less from the vast majority of people than 1000 hours of practice in the easiest cases for one to feel comfortable with them. There is a reason you can major in Swedish at Harvard but not Python. It is the same reason you can graduate having majored in Swedish at Harvard without actually being fluent in Swedish. It's the same reason. 1000 hours is a long time, and that is as easy as it gets.

You are drawing a strange and false equivalence between these two things, and I'm just not really sure what your point is. If your point is "these are secretly the same activity", my strongest response is "quantity has a quality all its own".

The "I want basic encryption for this subdomain but not announce it to the world" seems rather sane as well.

I dont need cert transparency either. I just needed encryption... Which a self-signed would be fine. But the internet powers that be deem self-signed as 'evil'. And more webtech requires SSL (like you, websockets). Can't even use it locally without SSL.

Paying $x00 for a SSL from some commercial vendor is laughable these days, unless you need a code cert or a onioncert.

I hadn't seen this before, thought it looks interesting. Wondered why it is perpetually unfinished... until I saw the 'Make an off-line version of this book' and 'Make a PDF of the book' sections.

Oh, OK. The authors have chronic obsessive abstraction syndrome, aka Endpoint Avoidance. What a shame.

Anyone have links to an actual PDF of it? Or a zip of the entire 'book' fileset?

My doctor sends out a monthly newsletter sharing things he finds interesting or useful, medical news, etc. Just this weekend he covered this study and shared his own thoughts on this, which I'll summarize since I haven't asked his permission to share verbatim:

This study does show a strong correlation but doesn't attempt to show causation. If cannabis users are significantly different than non-users in terms of activity levels or diet, or the ways they manage anxiety/pain/boredom, this could cause skewing. Since people use cannabis to treat (however effectively) various conditions, what is the risk of those conditions going untreated?

I thought this was a good analysis; glad to see a bit of desensationalism.

That isn't true. You are overstating the problem. I've built a custom fixed gear. I have 3 custom tools. They cost me £45 all together.

My current toolbox for the car is:

- Socket set (£50 halfords)

- Spanners (I already had these I guess £20-30)

- Allen Keys (£5)

- Several different types of Cir-clip pliers (£20-40)

- A battery powered soldering iron (£50-100). I have no mains power where I work on the vehicle.

- A lighter (£1)

- Mole-grips (£10-15)

- Axel Stands (£50)

- A Jack. (£100)

- Fuse Pullers (£3)

- Tub of Grease / Copper Grease (£15)

- Toolbox (£10)

- Stubby Screwdrivers (£10)

Do you realize how little people in these areas pay attention to these forecasts? Hurricanes until you hit CAT 5 are viewed as bad rain storms that may or may not take the power out for a week. There is little evacuation or prep for the majority of people there as they are consistently prepared. Even still, the real threat of a hurricane isn’t the hurricane itself but the storm surge and all the tornadoes they create. Neither of those can be predicted with any accuracy so please help me understand why pathing is important?

Great comment because I wondering the same thing. Do people not do any of those things on their own anymore? At a minimum, changing the oil was something I did with my dad as a kid. The hardest thing I've done was probably change a starter.

ICE's are conceptually pretty simple. Anyone who has built a computer should be able to do basic car maintenance if they want to. The electronics is what makes newer cars more complicated, and I assume EVs even more so.

You have to, because attackers aren't using canary systems. What good is it, if someone finds a new unauthenticated RCE in Windows, and you have to wait a week to make sure your detection method works correctly? By the time the week is over, every computer in the world already has the virus. And then you have to wait another week to test your removal tool.

I've always viewed these projects with a bit of suspicion - like I have trouble believing that anyone who does this actually does more with their tools than organize them and put them away. Which is fine if that's what you like, but not why I personally own tools. Shop time is limited enough as it is.

Also seems like a great way to add +50% plastic volume to everything you own. Incidentally, I've found the cardboard boxes that 3D printer filament comes in to be an excellent basis for general storage.

Working on a physical and digital archive of all American vintage print advertising. I've built the archival and database software on Lucee & MySQL to store images and automate, and I use OpenAI to analyze images and extra meta data. All of the full page ads are pushed to https://adretro.com.

I've gotten the process to fully catalog all of the advertisements in a magazine (about 150 on average) down from over a week to a few hours. I should be able to get through the material within my lifetime now :)

> A lot of time an used car is even more reliable than a new shiny car full of useless electronic components.

And a lot of time it isnt. Not everyone wants too or can afford to take that gamble. Sure, i've had luck with it, but that's because I can perform my own work upto and including dropping and replacing an engine if I need too.

On the other hand i've seen people who could least afford it end up with total stinkers that drained their wallets.

Remember, its citizens that made the country in the first place. These are all systems, and they operate under either stated, or unstated rules.

Either way, no one is coming to save you, other than your own ability to understand the system, its tolerances, and to effect change / build alliances.

You can even achieve this by doing something small, like cleaning up a local spot, or other parts of your daily routine.

We learn how to operate very complex systems regularly.

Agreed. For example, he strongly advises paying off one's house first. While this is good advice for many/most who struggle to save and invest, it's not optimal for maximising returns on a given portfolio. If the interest rate is below expected investment returns (minus tax and other subsidies, discounted for volatility), it can often be optimal to invest rather than pay down mortgage debt. It also means more liquidity in the case of sickness and redundancy. Equity in one's home can be difficult to access without some hefty fees or interest rates.

Man, I really hit that one out of the park with my choice of the word "insufferable"

These typical crossovers that most people buy are more or less a direct replacement for the sedans they used to buy. Sure they're probably statistically worse at the margin but people derive a bunch more utility out of them than the sedans they replaced, which is why the form factor is carried over as best they can to the compact and subcompact hatches (impreza, c-max, etc). You have every right to tell people they ought not to be doing what benefits them because of some nebulous change at the margin that's only visible once you apply a bunch of statistics, and I have every right to call you a moron over it. But what do I know, I drive a minivan.

No. Usually log without further specification is base10.

Except in mathematics and physics, where it usually is base e.

Except sometimes in computer science, where it can be base 2.

But there are more of those weirdnesses: "ld" can be "log decimal", so base 10; or "logarithmus dualis", so base 2. Base 2 is also sometimes written as "lb" (log binary). You really need to know the conventions of the field/subfield to know which is which.
by bityard | 2025-06-30 13:11:18+00:00
I don't know if it's due to social media distraction, very effective advertising business models, or lack of financial literacy but I have noticed that over the last 10 years, most people have been willing to pay literally any price for the things they want.

It wasn't always like this. It used to be that price hikes were met with consumer backlash, media attention, and people simply not buying that thing which forced companies to correct their pricing.

The fact that most people will happily pay any price they can afford (on credit, when) seems to be the main thing contributing to high food, car, and housing prices, which negatively impacts the poor and those who bust their ass to be frugal.

But hey, I guess it's a great time to be a VC.

Working on https://qrew.cc

When I worked at larger orgs. Reviewing applicants was a very busy task. I would usually get 100-300 applications for the role. And I never trusted HR team to filter out candidates before interviews, so I would go manually through all the candidates. In the world of AI and automatic ATS systems, I have the same problem. I don't trust AI now to filter and rank candidate resumes for me. I wanted something that enhances my process, but does not replace it.

So i've started working on https://qrew.cc, where AI helps you, but keeps you fully in control.

This is not the full story. As I mentioned in parent comment, ARM64 supports a special "contiguous" bit in its page table entries that, when set, allows a "block" of multiple contiguous pages to be cached in the TLB as a single entry. Thus, assuming 4k granularity, 64k "pages" could be implemented as contiguous "blocks" of 16 physical pages.
by GrantMoyer | 2025-06-30 13:11:30+00:00
> On average the precision is equal. The mantissa just adds linear segments to a logarithmic curve.

Yes, exactly; the linear regions are needed to more evenly distribute precision, while the average precision remains the same. Alternatively, you can omit the mantissa, but use an exponent base much closer to 1 (perhaps 1 + 2⁻²³).

As Milton Friedman has said, Market Failure is preferable to Government Failure. You are perfectly free to start your own coop or run a business to go against incumbent, and capital and government nowadays is quite enthusiastic to support you in that endeavor.

Americans also have never really lived under a heavy handed government, and that's reflected in the tone here of frustration of market failure. But when the government fails, it's not frustration that takes hold, it's fear. Are you willing to risk that?

Social media is a pretty wide term and includes networks where you mostly talk to your friends and relatives to networks where you mostly consume content from strangers.

The former has a clear benefit (especially where it challenges legacy industries with exploitative pricing like mobile phone networks) and even the latter can benefit you by exposing you to new ideas and information.

That social media is incentivized to push meaningless but addictive fluff over genuine communication due to monetary incentives is the point of TFA. This is a reason for making social media a public utility, not against it.

A glow plug is basically a heater.

Diesel being injected into the engine isn't ignited by a spark, but spontaneously by compression. This can't happen if the temperature in the cylinder is too low.

Having your fuel being ignited by the engine running, as opposed to something like a spark plug, has interesting side effects like dieseling and runaway.

I’m not anti-GC. There’s nothing wrong with using a garbage collected language. However, if you use a built-in garbage collector, you do need to play by its rules, or it’s not going to work. These rules are language-specific and limit what you can do efficiently when writing an interpreter, versus writing your own GC that’s purpose-built.

For example, Go’s garbage collector isn’t going to do as well at JavaScript as V8’s garbage collector, because the only unions it understands are Go interfaces. Also, the garbage collectors for other languages mostly don’t support some features of the Go language, such as taking pointers into the middle of objects.

You can still write an interpreter in any language, but there will be an efficiency cost when the languages are too different.

Curious to hear how others have handled scale challenges in billing infrastructure:

If you're running usage-based billing for AI, infra, or API-heavy platforms— How do you deal with high-throughput event ingestion (say, 10k+ events/sec) without dropping events or messing up customer metering?

We’ve seen setups struggle hard with:

Event ordering guarantees

Idempotency at scale

Handling retries without double-counting

Would love to hear what infra patterns, queues, or storage choices worked (or failed) for you—especially?

> - In 2005, there were around 10 new models under $15,000 (25k adjusted by inflation)

You'll need to provide hard evidence for this. I was pretty young in 2005 but $15.000 would get you a decent car (though not a pickup). That being said, it is possible we have more models now under 25.000 but what $15/25k used to buy you (segment wise) has downgraded.

I adore Geoguessr, but when I play it I wish there was a bit more strategy, or a longer term planning aspect to the game instead of purely memorization and clicking.

So I'm building it. Still early, and I have nothing to share yet, but I'm already pretty confident my Geoguessr friends will love it when it's finished.

Kudos, I think (in the short term at least) there is a large amount of perf. optimization to be found by coding parts of the whole AI/ML infrastructure in C++ like this one, not as a rewrite (god no!) but drop in and fix key bottlenecks. Anytime I see someone (seems Chinese engineers are good at this) put something out in C++, good chance some solid engineering tradeoffs have been made and dramatic improvement will be seen.

Others are sharing the sales tax rates by state, which is not the same as the auto sales tax rate by state, which is typically lower. Notably, there are a few states with no auto sales tax.

People have been known to cross state lines to purchase cars, to save a few hundred dollars on the purchase. In any case, a $10k vehicle is not going to cost over $11k post-tax in any state.

Get a wildcard for the apex domain/higher-level subdomain, the "secret" subdomain will be covered implicitly.

If you don't want the certificate to be in the CT logs, your only options are a private CA or things like CF Origin certificate, depending on how the domain is intended to be accessed.

It's not the end user that "needs" CT, it is a mechanism to ensure no shady CA can misissue a certificate without being caught. Requirements like that are written in blood (see Symantec).
