You really do live up to your name!

You imply that archive.org is somehow doing something wrong by letting "vagrants" sleep on their steps. I'd assert that people who are compassionate are more trustworthy than people who think punishing others should be normalized. I'd definitely prefer my backups in the hands of compassionate people.

The problem is that the people who want to see others be punished can't be trusted to, you know, not do that. Removing information about climate change, about vaccines, about trans care, et cetera, very well could happen at the hands of those who get off on punishing others.

You say the National Archives already does this. What happens when the current administration fires everyone and replaces them with non-professionals?

So I really don't know why you'd be in here talking ish about ArchiveTeam.
do we need a unit conversion for how many spoonfuls of plastic are in a plastic spoon?? seems like it might be important for this article.

Well article says a teaspoon has 7g mass, and just spitballin here but I'd say a plastic spoon has about 1g/cm^3 density. And there are 4.83cm^3 in a teaspoon. So I guess in fact there are 1.44 teaspoons of teaspoon in the brain. Or would that be 1.44 tsp^2...?

But I'm an American and I have at least 3 imperial teaspoons of microplastic in my brain or gosh darnit I'm 2 bald eagles short of a touch down. If you know what I'm sayin.[1]

Actually the source article is quite clear about the implementation of cronyism - friends were emailed the answers to the bizarre hiring test and others were not. It is typical behavior of machine politics - give good jobs to those who support you and block others from having them. Certainly the FAA did have DEI goals, but you can't attribute this patronage to them.
Lungs have been dealing with sand dust since there were lungs, have they not?

Honest science on a foreign material in the brain or body should be able to present a baseline amount of total foreign material for comparison.

If our environment is now 10% microplastics, then 10% of the foreign material found in the brain being microplastics would be normal.
>You are assuming you can match Gemini's performance

I'm not assuming. We already did, 18 months ago with better performance than the current generation of Gemini for our use case.

You're falling into the usual trap of thinking that because big tech spends big money it gets big results. It doesn't. To quote a friend who was a manager at google "If only I could get my team of 100 to be as productive as my first team of three.".
Isn't it about the same?

How big is a spoon, anyway?

> The problem is that RL is extremely inefficient.

Wait What? That is an odd way of defining it. That's like saying turing machines are inefficient way to solve TSP. You would , at the least, want to define this in terms of complexity or put this into context of domains and observability.

RL's by definition is a field that is about finding efficient problems in the domain of choice[1]. There are likely regimes in LLM/LRM learning where RL can be quite efficient, polynomial time even in the state space, we just need to explore and find them. For example you can use Dynamic Programming as a "more" efficient way to solve MDPs[1] because it is polynomial in the state space X Action space.

They were talking about logged in accounts, so you would group by accounts for the rate limiting and not by ip addresses.
Storing the bcrypt password in the entry would make a dump of the cache almost as good as a dump of the password database. At least this way a dump of the cache makes the key opaque and requires you to guess both the username/id and password together, assuming they're not repeated in the cache value.

According to the security advisory this cache was for AD/LDAP delegated authentication, so they don't have their own password database with a version field or similar for sensible invalidation.

I guess the requirements could be something like:

- different username/password combinations must have separately cached results

- mitigate a potential data leak by putting all the entropy we have available together with the password material and using a slow password hashing function

Stack traces are valuable and important, agreed. (In Scala it's pretty normal to use Either/Result with an exception type on the left so that you still get the stack trace). And it's definitely possible to carry an error state around too far when it's not recoverable and you should have just errored out earlier - ultimately you still need good coding judgement. "All functions end up returnig `Either/Result`" is a sign you're doing something wrong.

> Exceptions and panics can still creep so it's not even "safer"

This part is just as true for checked exceptions - you still have unchecked exceptions too. Ultimately you can't get away from needing a way to bail out from unrecoverable states. But "secondary state that is recoverable and understandable, but should be handled off the primary codepath" is a very useful tool to have in your vocabulary.

> Today I write C# at my job and I could not be happier with the usage of exceptions.

How do you do e.g. input validation? Things that are going to be 4xx errors not 5xx errors, in HTTP terms. Do you use exceptions for those? (I note that C# doesn't have checked exceptions at all, so there's no direct equivalent)
When you look out your eyes, that rectangular viewport is all your context. For example, we cannot fit Jupiter into your viewport.

So, if we can never fit large concepts like Jupiter into your viewport (your context window), does it follow that you will never understand Jupiter? Or is there no way to take a picture of Jupiter and make it smaller so it fits into your viewport?

See, coherence is just resizing or reimagining things so it fits into context. Context can never hold it all because we have the capacity to always imagine infinitely large things.

So I don’t fully know if it’s old context out, new context in, but could be just the right context, just enough of it, and just the right looking context so we can assemble the right worldview. This process would have to go on infinitely, and that is the world as you see and understand it.
Managed challenges actually come from the same "challenges" platform, which includes Turnstile; the only difference being that Turnstile is something that you can embed yourself on a webpage, and managed challenge is Cloudflare serving the same "challenge" on an interstitial web page.

Also, Turnstile is definitely not a simple proof of work check, and performs browser fingerprinting and checks for web APIs. You can easily check this by changing your browser's user-agent at the header level and leave it as-is at the header level; this puts Turnstile into an infinite loop.
Cool idea and something pretty common. Thanks for sharing! Hope it comes in handy.

There’s also gnu parallel to run many commands in parallel while staying close to the shell. I prefer to generate a list of directories & review manually, rather than trusting a tool which may do far more than expected. The dry run option is a great help here.

For anything recurring, it’d be wise to automate - run the script from a scheduled execution system with auditing, logging, monitoring, and alerts (in case the job doesn’t run, or fails, has unexpected output etc.)

And for this use case, these days you could also ask an LLM for a one-line shell command that will do what’s needed. Copy-pasting a one-liner is my sweet spot for minimal easily reviewed shell.

There is one final nit, and I know it’s not your idea, and you are just following convention - but man do those single-dash-but-long-form arguments trigger my OCD. Anyone know why Golang introduced them?
Show HN: RoundTable – An AI chatbot starter kit for Ruby on Rails
I've been learning everything I can about LLMs lately so I built myself a simple chatbot using Ruby and Rails.

I haven't seen a lot of AI projects built in Ruby or Rails so I figured I'd share the source of this one for the Rubyists.

The chatbot itself tries to simulate a roundtable discussion between you, Isaac Newton, Albert Einstein, and Nikola Tesla.

You can have them debate about anything from their thoughts on a unified theory, to the best way to organize your fridge.

Curious if anyone else is doing anything with LLMs in Ruby.

This is an incorrect usage of the word "mitigate." To mitigate means to lessen the risk. Mitigation requires action.

This is basically the only “social media” that I participate in.

I recently dumped Facebook (not that I was using it much, before), and never really got started on Twitter, Instagram, or TikTok.

I guess StackOverflow could be considered “social media,” as well, but I also almost never do much with it, these days.
>Intel SGX was never pushed on anyone

Considering that's the only way to play most DRM protected 4K videos, it's probably more of a "push" than requiring TPM. It didn't even have the fig leaf of being usable for FDE or webauthn.

>No "normies" are doing TPM bypasses. That’s the point. Majority will eventually be on unbypassable TPM.

If the bar is "normies", then you don't even need TPM. You can just slap denuvo or whatever and call it a day.
Costco people recommended showing up early. Went there right at opening in the morning and there was plenty. To their credit, they haven't raised their prices.

Also, shocked to see people hoarding multiple boxes of 50 eggs. Hoping it was for a commercial purpose and not someone panic-buying like they were for TP during the pandemic.
Hadn't heard of it either until up-thread so I looked. The two primary articles that were found on a search were from Reuters and the San Antonio Express News. Most other seem to just be referencing the Reuters article and using the same quotes. Tend to think the opinion up-thread is probably close, and SpaceX is basically not paying because they can, because people want the work, and because they can make more holding the money and delaying as long as possible, while eating relatively small fees.

There's also a "somewhat" unique one from MySanAntonio that goes over the general range of lawsuits that are being filed against Musk in Texas over a range of issues. It happens to include the Reuters article lawsuits and liens as one of the many listed.

>>environmental exposure concentrations ultimately determining the internal body burden.

As another commenter asked "How did the amount of brain microplastic manage to double between 2016 and 2025?" It is doubtful that the environmental concentration level doubled during this time.

dilution is the solution to the pollution
I think the root observation here comes from https://en.wikipedia.org/wiki/Fourth_power_law which really talks about the inferred stress to the road for given weight on the axle, not tire wear based on vehicle weight. The above seems to be using a simplification based on passenger cars staying with 4 tires across 2 axles but how this relates to tire wear is going to be a bit more complicated when you start talking about vehicles which can have more axles, more tires per axle, and significantly larger tires.

I'd believe buses have a lot of tire wear compared to an individual car but I wouldn't use that relation as proof of just how many times so.
Nonsense article, you could fit way more than that.
Perhaps you're thinking our body is at equilibrium with the amount of plastic in our environment, but the reality may be that our body accumulates microplastics from the environment and they become concentrated over time. Kind of like how we can't get rid of heavy metals from our body, so eating lots of fish accumulates mercury to toxic levels. But eating fish is a conscious decision whereas microplastic exposure is an unavoidable fact of life now.
The US has spent tax money to enslave and police Black people, exterminate Native Americans, deport Mexicans who were sometimes American citizens, and force Japanese American citizens into internment camps.

Sure but it’d be kind of weird if they chose to launder it through all these spammy accounts instead of doing it above board. I guess it’s more effective this way though. They get more reach than they would from their single obviously branded account, and as the rightsholder they know they won’t get any (valid) DMCA complaints. And at the end of the day, Google has no reason to care and users are happy. Sure it’d be nice if the clips didn’t have annoying background music but that’s the tax we pay to algorithmic incentives…
> These particles can include synthetic rubber, plastics, carbon black, and trace metals (like zinc)

you're correct. I mistakenly thought it was only carbon coming off the tires. So yeah, EVs have a significantly lower carbon output that ICE vehicles. My point still stands but thanks for the callout.
I own several Teslas, and based on first hand service experience, your concerns are warranted. Stay out of the ecosystem, lots of other good EVs to pick from (Hyundai Ioniq 6, for example). If nothing goes wrong during your ownership, you're fine. If anything goes wrong and you need service or support, it is a terrible experience.

Maybe this changes if Tesla fires Musk and puts someone competent and accountable at the helm (bring JB Straubel back as CEO, imho). I wouldn’t buy another Tesla until then.

Twitch is typically 6Mbps+ and 1080p, though with more time to encode you can get the same quality out of fewer bits. Netflix can go up to about 20Mbps for 4K if my searches can be believed, but I didn't test it myself. When I've grabbed videos off Nebula they're a lot bigger than youtube; one here that doesn't even have much motion is 4Mbps at 1080p. And crunchyroll has a lot of 8Mbps at 1080p.

But acceptable quality can definitely go smaller. Especially if "acceptable" is judged by the significant compression artifacts I see on actual cable TV all the time.
No, muscle memory refers to a different phenomenon where nerves outside of our brain can be trained and get better at skills.

I think what you're seeing here is that when you initially build muscle, you are building new muscle cells. When you lose those gains, you still mostly have the same number of cells, but they muscle fibers in them reduce. When you go to regain it, it's easier to regain because you still have most of the celluar framework there.

Or, at least, that's how it was explained to me. I probably have some details wrong.

I think Minimum Effective Dose applies. I quit most media for 4 years. The next 2 years were 2 hrs/day on Reddit for jokes. It was the best.

But 1 year into that, I read an article by Swyx on how to use social media. I tried but gave up for another 2 years. But the end of that last 2 years was the election...and I was curious...so I went to X.

Within 3 days my opinion of the outcome flipped.

And...since I already read Swyx's article, I was ready to effectively navigate other topics of interest.

But the key to effective media usage is to ALWAYS be on guard. Your mental filters have to be running all the time. The second you drop your guard, you're vulnerable because the stream never lets up.

But when you do this, you find that you quickly run out of truly interesting things to read. Luckily I've also got physical hobbies. I now spend a TOTAL of 2 hrs/day across all media, and my mental health is just fine!

But also I find it highly rewarding in many areas such as investing, history (the X format works so well!), international (language, culture, politics).

I also highly recommend taking a second to put each post in scale or context. This does 2 things: helps decide importance of post, and slows scrolling so your brain doesn't get DDOSed into a mental health crisis.

And the (increasingly cheap, powerful and ubiquitous) LLMs can be used to either save time or power you further into the conversations.
Does it have a negative effect on us though?

I mean, assuming I do have a spoon's worth of microplastics in my brain, I don't notice any impairment.
