From the guidelines- “Off-Topic: Most stories about politics, or crime, or sports, or celebrities, unless they're evidence of some interesting new phenomenon. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic.”
What's the tech context? What's the relevance for this community?

If somebody has a point to make about the role of social media in this kind of thing, or close user groups fomenting outrage then I guess we have something but to date the links I see are plain reportage.

hype is the deeply engrained norm in our industry, bro. just sit it out. as that famous saying says, "this too shall pass.".

until the next one, of course. ;)

for example, in rough order, some past hype trends: 3GLs, structured programming, initial AI (then AI winter), expert systems, CASE tools, 4GLs, OOP/OOAD, UML and round trip engineering, design patterns, dot com boom (and bust), agile, functional programming, Web 2.0, SaaS, crypto, Web 3.0, big data, data science, ML/AI.

most of them had or have some actual benefits, but nothing like the hype parrotted, by those with and without vested interests.

been there, seen them, from the third or fourth one onwards.
The insight from decades in exploration is "all anomalies are interesting"; the background drone matching helps to find the things of interest (until they're common and understood) - cats fighting, cats having sex, kittens stalk playing, etc. are all going to have differing (and overlapping) fingerprinting.

As with many projects of this nature there's very little more to say at this point in time until there's a pile of data to start wading through :)

Maybe someone will run with it.
Ask HN: How do you prepare for interviews?
Hi HN, I'm trying to create a tool that helps people with preparing for interviews. I just released the first version, but based on my analytics and some interviews, I've realized that no one really cared for the tool since it didn't solve a big problem people had.

Now, I'd like to understand the problems/challenges people face when preparing for interviews, so if you could answer some questions, that would be greatly appreciated!

- What industry are you in (i.e, SWE, product, etc...) and how do you usually prepare for interviews?

- In your last interview prep cycle, what was the biggest challenge you faced when preparing for interviews?

- What tools do you usually use to prepare for interviews (i.e., leetcode, exponent, algoexport)?

- Name one thing you dislike about those tools, and one thing you like about those tools

Thank you in advance!

Gun ownership areas and GDP in the US are almost entirely negatively-correlated.
Yes I understand the traditional objections to this idea. I don’t think you’ve quite grasped what I propose tho. Consider this: The reaction v_e + (71)Ga → (71)Ge + e− involves the release of an electron. The local electronic environment, including electron orbitals or metallic bonds in liquid gallium, can influence this electron's energy levels and spatial distribution. These changes can affect the reaction rate and shift the equilibrium position of the reaction, potentially making the forward reaction less favored and accounting for the 20% discrepancy. So, while neutrinos primarily interact via the weak nuclear force, the electron release means the local electronic environment can subtly impact the overall reaction dynamics.

Well, the article actually admits that 95% of hydrogen produced in the US is from hydrocarbons, and thus produces lots of CO2.

And if you think about it for a minute: Do CO2 emissions that occur miles away from where I'm standing right now really even exist?

Some of us are reusing!

There are numerous single-use devices in healthcare for sterility purposes. One common device hooks up to vacuum and fluids and provides irrigation and suction capability in laparoscopic surgery cases, and it uses 8 AA batteries that are sealed in at the factory. At the end of the case, the device is discarded.

It's pretty standard for people to take the batteries out (they've barely been used) before throwing it away. I haven't bought AA batteries in nearly two decades.

I’m personally very excited for this book. When I would get programming books at the library as a youth, it would be a gamble as to “introductory or advanced?” and I needed the former way more. “3D Rendering in X Windows” wasn’t great at for me at 13, and getting into topics like this takes a solid foundation.

Ask HN: What would it take to make a robot vacuum in the USA?
There is no robot vacuum manufactured in the United States as far as I can tell.

It seems crazy to me---these devices map out the interior of people's homes and businesses, often with cameras running and a wifi connection to the Internet. Talk about an espionage giveaway... all to a certain authoritarian country in Asia which manufactures 95% of the devices.

I used to be a big free trade advocate but have come to feel that free trade is something of a gift, which should be given mainly to countries whose vision of the world is compatible with ours. It also should not be allowed to undermine security-critical technologies and capabilities, such as electronics and microprocessor manufacture, etc.

In spite of recent tariffs and moves to restrict exports of sensitive technologies, the tech ecosystem in the US seems to be in a seriously impaired position.

If one were to push back against this and try to launch a robot vacuum product assembled in the USA of US-made components... what would it take? What are the economic impediments to doing this in a profitable fashion? Is there an economic policy that would make this feasible?

It seems there are a number of key components:
* Microcontroller
* Sensors
- laser or lidar to map environment
- something to determine floor type / depth
* Bluetooth antenna to interface with a mobile app
* Vacuum
* Dust compartment
* Dock to autoclean
* Embedded software
* Mobile app

Such a device would be an ideal candidate for training using reinforcement learning. (Has this been tried? Or is "robot vacuum" already a solved problem?)

My training is in software and machine learning. Yet it is in on the material side of things where the U.S. lags the most. There are so few physical things of relevance to modern life that we are making here these days, and even fewer at a competitive price point.

Would love to hear others' thoughts. Thanks

2A was always meant to be about individual ownership.

At the time the rationale for a right was frequently included in the text, just as a modern reading of the right implies it is being used as an explanatory clause. The entire concept was that there would be no governmental army and in times of need, citizens would be able to use their arms and organize for mutual defense. In this context, "Militia" is synonymous with an decentralized armed citizenry without government oversight. The clause provides this rationale and coveys a sentiment against a standing army. here are what some state constitutions had to say about gun ownership, prior to the bill of rights.
Article XIII of the Pennsylvania Declaration of Rights of 1776 read:

>That the people have a right to bear arms for the defence of themselves and the state; and as standing armies in the time of peace are dangerous to liberty, they ought not to be kept up; And that the military should be kept under strict subordination to, and governed by, the civil power.

Similarly, as another example, Massachusetts’s Declaration of Rights from 1780 provided:

>The people have a right to keep and to bear arms for the common defence. And as, in time of peace, armies are dangerous to liberty, they ought not to be maintained without the consent of the legislature; and the military power shall always be held in an exact subordination to the civil authority, and be governed by it.

James Madison produced an initial draft of the Second Amendment as follows:

>The right of the people to keep and bear arms shall not be infringed; a well armed and well regulated militia being the best security of a free country: but no person religiously scrupulous of bearing arms shall be compelled to render military service in person.

We don’t even know the motives of the shooter yet. Let’s not hyperventilate and give it a few days, there will be a drip drip drip of info, he probably has a trail online, they usually do.
Please look up the incorporation of the bill of rights. It is clear that the Bill of Rights did not apply to the states. That is why several states actually had state churches after the bill of rights.

It's directly called out in the guidelines - I'm not entirely sure what you're curious about.

"The JFK Assassination" as a discussion of politics would be immediately flagged. Your linked [1] search is almost entirely comments and not a topic of discussion, which you would've realized quickly had you clicked through any of the results.
If that is a fear, then maybe don't kill him until he actually has done the thing you fear. Killing somebody before they do the bad thing seems like killing people for thought crimes.
Trump and Biden are judged by different standards. Trump told well over 30 hard core lies at the debate, many blatant lies. Joe got called out on 8 or 9, but they were almost all just slightly off statistics or bad recall, but still “truth” and not blatant gaslighting. What got him were his senior moments.
Should be a by default opt out. Why do I even need to request this.
I think as a rule of thumb, latest generation hardware makes the most sense for cloud compute providers supporting AI. But while yes, training can be bottlenecked easily by internode training speed, it really depends on the model, model size, how you’re doing the training (DDP? FSDP? Custom sharding?). I’ve seen bottlenecks there, but usually it’s on the latency side of things, and you won’t really see an improvement there moving from Infiniband HDR to NDR. Preparing hardware for a generic cluster with changing or unknown workloads, yeah max it out and build the most flexible fabric you can. But if you know your model, you can optimize your hardware to it.
also, see this cperciva comment, and Google who he is before replying:

The National Archives and Records Administration has standard procedures and approved vendors for this.[1] One of their approved vendors, Colorlab, has 1" type C equipment.[2]
Colorlab is conveniently located just outside the Capitol Beltway, about 20 miles west of NSA HQ at Fort Meade. Colorlab does preservation and conversion work for the Library of Congress, Warner Bros., Universal, NBC, The New York Public Library, Paramount, HBO, etc.
NARA has a standard form for government agencies requesting this service.[3] It looks like it's not even charged against the sending agency - Archives picks up the bill.

The linked article says this was recorded in 1982, so it probably was recorded on Ampex 1" Type C, which was pro-grade at the time. Not sure how the 1950s got into this. 1950s video tape would be 2" Quad, which Colorlab can also read.

That's definitely a concern. Players call getting stuck by others' checks "BK'd" because a player once went out to get Burger King and returned before they got unwalled. But I think sharing the challenge/frustration and randomness with other players is the fun part, and that's what makes this such an interesting way to play games.

The organizer can also kick inactive players out and release their checks. You could play solo with one or multiple games.
The author's name seemed vaguely familiar. He was involved in the 2011 email leaks from Stratfor and spent time in prison for it. Although the article notes that he "declared political asylum in the United Kingdom in 2021 and currently lives in London", it looks as though his request for asylum was denied earlier this year.

He means that when people are screaming at you to do something because the market's tanking, you earn your salary by yawning and saying, "No, I think we're good."

If you made everyone in the world not want to hire someone via impersonation, then that's very blatantly libel. How would it be hard to prove?
Short answer re: investing in active managers (based on my many years listening to rationalreminder.ca) is that, if you eliminate some of the worst active managers, the average returns net of fees are the same. However, eliminating the worst managers is challenging (but not impossible) to do ex-ante. Even then, you’re only getting the same average returns as indexing, not better. Plus, you will experience a higher dispersion with active managers (greater chance of extreme negative or positive outcome), which is not desirable. Because of these two issues, It’s definitely better to pick an index fund.

Re: picking stocks yourself, the answer is also pretty cut and dry. There’s strong evidence no individual trader can expect to beat the market. Active managers can only beat the market gross of fees because they employ large teams of people to do a lot of work to gain a small edge (stuff like predicting retail sales numbers from satellite images of store parking lots).

This is my attempt at summarizing a whole field of research in a few sentences. There are many more nuisances. I highly recommend listening to the Rational Reminder podcast if you’re curious about this sort of thing. They interview a lot of academics.
I don't see them as competing strategies, do all of it.

Patreon probably will give more dopamine hits as you get to feel like you're building a community as seeing it grow. The musician approach I assume is a hard grind. Months will pass with hours invesred and no conversions, so probably has a higher give-up rate. I'd do both. I'd also set some traction/revenue goals as I can see this turning into more of a hobby (earnings/time is very low)
Yeah those crypto cards were nerfed. Truly e-waste, I’d love for someone to figure out some innovative ways to use them, maybe with some unhinged hardware mods.

AVX-512 is no longer ubiquitous on Intel servers, but only on new AMD servers.

Even earlier, there were cheap Intel servers with CPUs using Atom cores, for example the Denverton, Snow Ridge, Denverton Refresh, Snow Ridge Refresh, Parker Ridge and Arizona Beach series of server CPUs. None of these supported AVX-512 and many did not support even AVX.

However, now, after the launch of the Sierra Forest server CPUs, which will be followed next year by the Clearwater Forest server CPUs, the Atom cores have expanded up to the biggest Intel server CPUs. While such server CPUs are intended for applications where computations using array operations are less important, like Web servers or the hosting of many small virtual machines, the fragmentation of the Intel ISA is extremely annoying, especially when AMD demonstrates how they can implement the same ISA, but at different levels of performance (by varying the number of vector pipelines and the maximum achievable clock frequency) both in laptop CPUs and in desktop/server CPUs and both in compact cores with low clock frequency and in big cores with high clock frequency.

At least for me, the lack of AVX-512 support is the reason that made me stop buying Intel CPUs already some years ago, even if there are some features of the Intel CPUs that I prefer over the AMD CPUs (like TSC deadline), but none of those can compensate the lack of AVX-512 support.

The greater width of AVX-512 is not its greater advantage, but the mask registers and a more complete set of instructions, which simplify many algorithms. Therefore when Intel will support AVX10/256 across all their CPUs, that will partially restore the competitivity of the Intel CPUs, but that is not likely to happen before 2026.
