Does this word mean "not the way things mathematicians teach things"? My experience has been that mathematicians teach things that are useful to mathematicians to students who are not going to be mathematicians and would be better served learning other things. I wasted countless hours of my life finding analytical solutions to toy calculus problems in a universe that will never yield to those methods.

>My stance on quaternions is that they are an opaque representation of what they are trying to do, which makes them unnecessarily-difficult and annoying. Not to mention hard to learn to visualize.

I've seen some remarkably confusing attempts to understand and visualize these things. This has always baffled me because the equivalent objects in geometric algebra aren't that hard to understand. I really think this is a problem with your pedagogy. You've hidden the geometric meaning of the bivector components in these imaginary components, i,j,k, and you have to take it on faith that i*j=k and instead of it being just the product of two bivector blades.

>The notion of an exponential map and exponentiating generators is, IMO, much more "natural" and intuitively straightforward than the alternatives.

That's because you learned it that way. Exponentiating an oriented area to generate a rotation is perfectly intuitive to me, and I'm not sure how somebody could be confused by the fact that a bivector can be an oriented area or the logarithm of a rotation because it's a simple matter of context.
In terms of the low stakes feel, I think calling it a “boss blind” is really the only thing that I could possibly point to critically.

It’s amazing how that one word can change the entire vibe. It evokes a much more serious feel to it for me. Not sure what I’d call it, but I wonder if a different word would suddenly alter the whole vibe just a bit more towards that stated goal in the first paragraph.
Richardson specifically, but honestly most of DFW. Pretty much any apartment complex built in this area in the past 20 years is corporate owned. These days even a lot of the townhouses around are corporate owned rental units.

In fact, this area (and other places in Texas) has given rise to a new kind of apartment architecture called the "Texas Doughnut", which is a 5-over-1 apartment complex wrapping a central parking garage and often other courtyards in the middle. These things are everywhere in DFW. Just take a peek on Google Maps.

But it is not just DFW. A lot of other cities in the US have similar things going on. It seems like most cities I'm in often have most new apartments I see be corporate owned units, not a lot of individual ownership.
This is a different feature to allow sites/companies to see which of their users may be compromised to help facilitate resetting credentials.

I did figure out the other issue though. If you got the email saying you were part of the stealer log leak, you can find a link in the of the bottom email titled “check my email address again”.

Follow that link and scroll all the way to the bottom and you should find a section for “stealer log entries” which includes domains that tour email address was associated with.

What Complexity Theory Can Teach Mathematicians.
Mathematics isn’t just about knowing whether something is true—it’s about understanding why it’s true. And as it turns out, different proofs often provide different insights. But what if there’s more? What if there exists an optimal proof—a proof that, in some sense, is the best?
How do the two versions match so closely? They have the same content in each paragraph, just worded slightly differently. I wouldn't expect them to write paragraphs that match in size and position like that.

Streaming algorithms for embedding and computing edit distance in the low dista [pdf]
You go into this process with a perspective, you do not build a solution and then start looking for the problem. Otherwise, you cannot estimate your TAM with any reasonable degree of accuracy, and thus cannot know how much to reasonably expect as return to expect on your investment. In the case of AI, which has had the benefit of a lot of hype until now, these expectations have been very much overblown, and this is being used to justify massive investments in infrastructure that the market is not actually demanding at such scale.

Of course, this benefits the likes of Sam Altman, Satya Nadella et al, but has not produced the value promised, and does not appear poised to.

And here you have one of the supposed bleeding edge companies in this space, who very recently was shown up by a much smaller and less capitalized rival, asking their own customers to tell them what their product is good for.

Not a great look for them!

Another option is to set the full $PATH value explicitly instead of doing an add thing for each directory. This avoids duplicates and the extra logic, but maybe isn't as convenient.

Why would you use either when there is OpenBSD w/ carp + HAProxy?

There's lots of options out there. I mean, even IIS can do RP work.

For a lot of shows now, I just wait for the show to finish and look/ask around for the best first season episodes to watch.

I watch those and then if I like the show I’ll watch a few more but most of the time they don’t hold my interest so much when I’m not being drip fed new episodes.

I watch virtually no live TV now but do like to catch up with NBC shows on Peacock the next day for a couple things.

I’ve started buying DVDs again in the last few months. I have lots of stuff in my queue to watch.
Iirc, Riva 128 only supports 8 of the 32 D3D5 blend modes, or something. Usually in the case of GPUs that don't support all blending modes the Direct3D HAL will attempt to compensate by using a different blending mode, or just give up and render opaque pixels. The results are usually pretty ugly. Riva 128 is one of the better ones for the era in this regard.
> And presuming we elected folks to set tax rates and make decisions to spend that money helping people, I don't see anything ignoble about choosing to help manage that process.

I never said it was ignoble. I just said it wasn't particularly noble. I think a SpaceX engineer making a shit ton of money to develop re-usable rockets and thus putting America ahead of every other country is doing a more noble occupation. I even think a financier enabling spacex to do that work is a more noble occupation.

> But like given your whole "taking money on the threat of violence" quote, either you're a super-libertarian who 99% of the country disagrees with anyways.

I'm actually not a libertarian in the slightest, and think the tax rate should be significantly higher. For example, many states in this country continue to release violent criminals due to supposed lack of jail space. This is honestly insane in a country as rich as the United States, and we should raise taxes as high as necessary so that lack of space is no longer a reason to not make violent criminals complete their sentence (or stay locked away for life, if that is the sentence). I would support a 100% tax rate on nonessential income until we have the basic infrastructure necessary to run a civilized country.

> Or you do think the Government should spend money on things and maybe it's noble to be the person who does that (military etc.)

No, in general, government work is no more noble than private sector work. The a priori is that it's less noble since your entire livelihood depends on forced threats.

> You just disagree with this particular spending of the money in which case... Ok.

Well yes, you see, us non-libertarians don't magically all agree on what to spend money on.

If the torrent is already well-seeded it's ok, a 1567th seed won't make a difference so don't bother with them. It's the less seeded torrents where you can put some efforts and do something good.
Who's the target audience for this pricing that can afford this? The RUM pricing is indeed quite ridiculous.

It feels quite ridiculous, especially if you are managing "soft" resources like IAM roles via Terraform / Pulumi. At least with real resources (say, RDS instances), one can argue that Terraform / Pulumi pricing is a small percentage of the cloud bill. But IAM roles are not charged for in cloud, and there are so many of them (especially if you use IaaC to create very elaborate scheme).

> but greater is a geographic term and doesn't mean "better" instead it's closer to "wider" or "covers more area."

You are confusing a specific geographical sense of “greater” (e.g. “greater New York”) with the generic sense of “greater” which just means “more great”. In “7 is greater than 6”, “greater” isn’t geographic

The difference between “greater” and “better”, is “greater” just means “more than”, without implying any value judgement-“better” implies the “more than” is a good thing: “The Holocaust had a greater death toll than the Armenian genocide” is an obvious fact, but only a horrendously evil person would use “better” in that sentence (excluding of course someone who accidentally misspoke, or a non-native speaker mixing up words)

Probably because it's sourced from your distro provided /etc/profile. Bash will only source .bashrc on its own in some cases.
It's not the latest type of pretty, though. It's very important that every few years you throw out all usability/accessibility to replace the user interface with one that is the latest kind of pretty, then if you feel like it, slowly add back usability/accessibility features until the cycle repeats.

You'll see that an adversarial node either is too adversarial and will be cut off, or still gives just enough to not be cut off but if there are other, more cooperative nodes, they will be favored. Being adversarial doesn't work in the long run.
It seems like the author is agreeing that HTTP/2 is great (or at least good) for browser -> web server communication, but not useful for the REST-style APIs that pervade modern app design. He makes a good case, but HTTP was never really a good choice for API transport _either_, it just took hold because it was ubiquitous.

Your reasoning follows the exact playbook that is repeated by architecture professionals around the world. It is exactly these kind of statements that lead me to comment in the first place.

No, architecture is not high art. It is the most public of arts and hence needs to serve the people. And people know very well which environments they like and which ones they don‘t. Where they find emotional well-being. That is not a political question at all. The studies are consistent.

We also don‘t need a theory. Architecture is a bunch of patterns and insights into human nature that has been known for thousands of years.
> Is there a source for this?

For the claim that Slim had criminal ties? No, not really.

The immediate source was this tweet, which asserted, without any clear basis, that Slim has "significant ties to the drug cartels in Mexico": https://x.com/wallstreetmav/status/1882255277551972619

The linked NYT article in the reply-to was https://www.nytimes.com/2025/01/22/world/americas/mexico-car... (archived: https://archive.ph/6Sn0Y), which doesn't mention Slim at all.

Please tell me how we objectively determine how correct something is when you ask an LLM: "Was Russia the aggressor in the current Ukraine / Russia conflict?"

One LLM says: "Yes."

The other says: "Well, it's hard to say because what even is war? And there's been conflict forever, and you have to understand that many people in Russia think there is no such thing as Ukraine and it's always actually just been Russia. How can there be an aggressor if it's not even a war, just a special operation in a civil conflict? And, anyway, Russia is such a good country. Why would it be the aggressor? To it's own people even!? Vladimir Putin is the president of Russia, and he's known to be a kind and just genius who rarely (if ever) makes mistakes. Some people even think he's the second coming of Christ. President Zelenskyy, on the other hand, is considered by many in Russia and even the current White House to be a dictator. He's even been accused by Elon Musk of unspeakable sex crimes. So this is a hard question to answer and there is no consensus among everyone who was the aggressor or what started the conflict. But more people say Russia started it."
> It sounds like it's so expensive and the difference in usefulness is so lacking(?)

The claimed hallucination rate is dropping from 61% to 37%. That's a "correct" rate increasing from 29% to 63%.

Double the correct rate costs 15x the price? That seems absurd, unless you think about how mistakes compound. Even just 2 steps in and you're comparing a 8.4% correct rate vs 40%. 3 automated steps and it's 2.4% vs 25%.
I never said it was only in American speech, just that it's very, very common, to the point where a lot of what Americans said made less sense to me until I realised it.

For an open source product, it's fun to say "written in X language". It also advertises the project to developers who may be willing to contribute.

If you put "product made with Go", I'm not going to contribute as I don't know Go, though that wouldn't prevent me from using it should it fit my needs. But if you wrote your project in .NET, I may certainly be willing to contribute.

Yeah

- you need code execution on the victim device

- you need internet connectivity

- you need bluetooth permission

- if the victim device has GPS itself, then this attack is pointless because you may as well just use that directly.
I doubt it required floating point rgb and, iirc, it came (for real) much later. GPUs used fixed point math behind the scenes for a long time. The only thing you need to get proper additive blending is saturation, so that you don't overflow, like on the N64.

My university uses SharePoint to upload course classes material, and it's slow and buggy as fuck. Every minute spent using SharePoint, I'd rather it be spent in being kicked in the balls. Every interaction I have with SharePoint is frustrating, it's one of the worst thing that happened to my life and I was happy before this software.

This sort of thing is why nobody gives a shit about IBM anymore and they have to keep just buying relevant companies to stay relevant.

Hopefully they do the right thing and hand hashicorp over to Redhat so they can open source the shit out of it. So they can do things like make OpenTofu the proper upstream for it, etc.
No, API gateway is a web service that has a main purpose of routing requests based on incoming requests.

Show HN: Scholium, AI Research Assistant
Hi HN!

I made an AI research agent that finds, summarized, and cites papers based on your query.
I’ve written my fair share of papers in university and I’m a copy editor for our student paper as well.
When fact checking, I noticed that Google often recommended unreliable scholarly sources(Medium articles, Reddit comments, and Linkedin posts) first. For example, when you search for Transformers, the first 6 results are blogs and articles. It is only on the seventh that you get the Vaswani 2017 paper. This makes fact checking and source gathering very tedious and time consuming.

I realized a lot of the repetitive work done in fact checking and source collection could be solved using a vector database and a retrieval model, which inspired me to create Scholium, an AI research agent that recommends and summarizes papers based on your query. Currently it only has access to all arXiv papers, but I plan on expanding the corpus soon!
Please check out the repo and give it a star. Let me know what you all think!

TL;DR Yes, because the current AI has the same last-mile problem as the tech around self-driving cars.
Musk really seems to have lost his mind and any kind of filter. He hears about something and tweets it without any thought. Pretty much the same approach he is using with DOGE. Look at something for five minutes max and if you don’t like it understand it, cancel it.

My theory is that anybody who engages a lot on X for a while gets their perception of reality totally distorted. If US leadership keeps passing off the whole world I think the real winner of “America first” will be China and Russia.
Pulumi’s RUM pricing is why I was very hesitant to even evaluate it as an alternative to just using terraform.

>I think you've missed something important: none of these elements in Balatro are monetized.

Monetization doesn't really affect addiction, which was the question at hand.
The wait method can only be invoked when the object is locked (e.g. within a synchronized block). The method throws an IllegalMonitorStateException otherwise. This implies that the map access is protected by that lock. Entering the wait releases the lock, and leaving the wait reacquires the lock. Those lock operations also imply a happens-before ordering, meaning changes made to the map by another thread during the wait are guaranteed to become visible to the current thread.

The code is perfectly correct, and straightforward if you’re familiar with Java concurrency basics. Wait and notify were designed to be used in that way to wait for a condition. This is (or was) a common Java synchronization idiom:

https://wiki.sei.cmu.edu/confluence/display/java/THI03-J.+Al...

https://docs.oracle.com/javase/tutorial/essential/concurrenc...

Regarding the “small chance of a race”, the code’s whole purpose is to remove that race by synchronizing properly, which it does. The author presumably didn’t show the surrounding lock because it is implied by the wait, and because they were assuming their audience to be familiar with the idiom.
Awful performance. Usually 2x worse than C and 4x worse in the worst case. Given the comment by Fil-C's creator minimizing the performance issue [0], I wouldn't get my hopes up.
