A precise answer to that question entails more math than I'm willing to do right here in the middle of my Easter holiday. You should understand my argument more as a sketch of proof.

That being said I have a small correction. If you want to stream to two peers (that is you have a network with 3 fully connected nodes, one being the originator of the stream) and the link latency for all links is 20ms, then your lowest latency path to each node is exactly 20ms, as the originating node could simply send the content to each client.

The unfortunate realization is that 20ms is then also the optimal stream delay, assuming you care about the shortest possible latency for your live streaming service. The clients will therefore end up with the content exactly when they were supposed to show it, and therefore they would have no time to forward it to anyone else, lest that downstream would get the content AFTER they were supposed to show it.

at some point my take became: if nothing orders the stuff that lies and flies around, any emergent structures that follow the laws of nature eventually break down.

organisms started putting things in places to increase "survivability" and thriving of themselves until the offspring was ready for the job at which point the offspring started to additionaly put things in place for the sake of the "survivability" and thriving of their ancestors ( mostly overlooking their nagging and shortcomings because "love" and because over time, the lessons learned made everything better for all generations ) ...

so entropy is only relevant if all the organisms that can put some things in some place for some reason disappear and the laws of nature run until new organisms emerge. ( which is why I'm always disappointed at leadership and all the fraudulent shit going on ... more pointlessly dead organisms means less heads that can come up with ways to put things together in fun and useful ways ... it's 2025, to whomever it applies: stop clinging to your sabotage-based wannabe supremacy, please, stop corrupting the law, for fucks sake, you rich fucking losers )

> Brexit literally just resulted in the UK having lower tariffs

That is, of course, entirely false. In that the UK does not, in fact, have lower tariffs, and even if that would be the case, there are many downsides that don’t have anything to do with tariffs.

> and a probable free trade deal with the largest economy on the planet

The FTA with the US has been "happening soon" for about a decade now. I’ll believe it when I see it. And with a protectionist American government, it would put the UK at a significant disadvantage.

> unlike our friends on the European continent

LOL. Nobody on the continent wants its country in the same position as the UK is. Brexit killed any political movement to leave the EU for a generation.

> If a wifi password is required to make full use of the device, I will return it.

This is one of my favourite uses of OpenWRT, or any other firmware that gives you proper control over the router - for WiFi-networked IoT devices, I set up a separate wireless network with no WAN/LAN access and client isolation. I can connect to the device, but it can't connect to WAN, any other devices on the IoT network, or my LAN.

Of course this won't work for cloud-tethered devices, but many will expose their functionality directly over network.

The attack is being described as “sophisticated” but we can thank our (GitHub) stars that the exfil was a half-assed job that ultimately made only public repos vulnerable and made it obvious in logs whether a compromise occurred.

It’s almost like a grey-hat attacker trying to make the supply chain vulnerabilities more visible without doing major damage themselves. Almost.

I really loved Phind and always think of it as the OG perplexity / RAG search engine.

Sadly stopped my subscription, when you removed the ability to weight my own domains...

Otherwise the fine-tune for your output format for technical questions is great, with the options, the pro/contra and the mermaid diagrams. Just way better for technical searches, than what all the generic services can provide.

Combined with "oops can't get them back" it's very powerful. Combine it with not advertising faces of snatched people on broadcast TV, and it's a very useful tool inded. People will just disappear. It won't be legal or illegal, just a thing that happens from time to time. Police won't search too hard for the missing people, because no good can come out of finding out.

>Just to be clear, nobody was unclear about that

Oh, you were quite unclear. Also wrong in saying you need systemd with podman to orchestrate multiple containers without root.

>It is, just to be clear, red hat's recommended way to orchestrate podman containers despite having this nasty dependency analogous to the one docker has on a root service.

It's not "red hat's recommended way to orchestrate podman containers" in general. It's "red hat's recommended way to orchestrate containers on top of systemd", that its whole point.

Nothing nasty about it either, you'd already be running systemd on your redhat system (and many non red-hat ones).

Rode the Shinkansen twice in the last week (Tokyo<->Osaka). Not the most scenic, but you do have a spot where you pass Mt Fuji.

Not sure if this route goes the full 320 km/h but it was plenty fast!

Loved the convenience and ease though. Having to schlep to the airport and deal with all the hassle of flying sucks by comparison.

Rock up to the station, buy a ticket, wait 30 minutes and go.

The disadvantage is that LLMs are probabilistic, mercurial, unreliable.

The advantage is that humans are probabilistic, mercurial and unreliable, and LLMs are a way to bridge the gap between humans and machines that, while not wholly reliable, makes the gap much smaller than it used to be.

If you're not making software that interacts with humans or their fuzzy outputs (text, images, voice etc.), and have the luxury of well defined schema, you're not going to see the advantage side.

They've already sent an innocent man there and acknowledged he was innocent, then refused to bring him back when the courts, the opposition and finally SCOTUS each commanded them to bring him back.

This was just a test, and it was successful. They can now disappear and deport anyone they want with no repercussions whatsoever. The GOP is a criminal organization and their followers share the responsibility of what happens next.

Congress delegated tariff power to the president after Smoot-Hawley caused such a disaster.

> The reason the President doesn't have this power is because the economy should not rest on the whims or understanding of any one person.

It's interesting to see that it just takes time for lessons to be un-learned. The reason Smoot-Hawley was such a disaster is that it took hundreds of people to agree that it was good policy in the house, which meant adding tariffs to the bill in favor of the districts they individually represented. The result was an egregiously long list of things being tariffed. They delegated it to the one person specifically because they weren't similarly beholden to so many conflicting pressures.

I don't mean any of this to defend Trump's actions, in fact the opposite: he's essentially managing to do the same thing even without politic pressures to do so. I just mean to say that it is reasonably sane for congress to have delegated tariffs in a limited capacity when this flaw was revealed.

I understood that you don't believe it can be made reliable. But my question was: what if it were?

Let me put it differently. Suppose I don't tell you it's ML. It's a machine that you don't know how it works, but I let you do all the tests you want, and turns out they're great. Would you then still be against it?

Bootlin is a French company and they are a major open source contributor. I worked with them and I recommend them.

French tech used to have a reputation for Renault old car quality, but I did not see it. Even in Renault and Citroen I came to admire them. On the other hand working with German SE is hard because they are incredibly set on not invented here. My generalisation for whatever it is worth.

In general the issue of Europe tech scene is simple: we suck at selling and optimise for resource efficiency(competitive salary means never pay above rate no matter what). Americans optimise for growth and will risk paying for higher so they can amortise costs with growth.

On a final note, where I come from there is lots of sneer that France is a dump due to immigration. While that is a point of view, it is definitely true they have also brain drained their colonies and have very capable productive individuals coming from there. Myself I had my master’s tutor from cot-de-Ivoir and in bootlin also worked with top of the shelf engineers that have non francophone names.

The way to think about it is you're not describing the work you've done, you're describing what the commit does.

It makes more sense that way if you think about the way in which Git is used for Linux development. They review individual commits so the commit message describes the change that will occur if that commit is pulled. Also commits can have multiple revisions as the change is improved, so past tense isn't correct because it can still change.

Do you think that 4chan is going to disappear forever for this? Just wait a bit and it will be back.

Also where did you see that they are leaking home addresses and work contact info? I think they just leaked the emails (I don't understand why home addresses and work contact info should be present in the 4chan database, everyone moderating the site for free).

I'm too much the artist, I find. I tried shooting my D850 in B&W and it's as good as I would expect from a color sensor with a Bayer filter. But it feels like I'm just giving up all the degrees of freedom Lightroom can give me when converting a color raw, and there's a degree of "push" and "pull" processing flexibility that doesn't seem easily replicable by other means.
by robobro | 2025-04-15 12:08:07+00:00
The initial leaker is most likely not the same parties as the ones tying email addresses and usernames to people's "real identities", if you look at the thread where the leak was announced.

Say what you will about 4chan but I am concerned for the team managing it - them and their close ones are certainly going to be exposed to a whole lot of viciousness soon :(

If demand is elastic, then the seller has to lower prices (and their margin), otherwise people don’t buy their stuff (because they can do without). In this situation, the seller eats the tariffs, That’s the case for nice-to-have things like luxury goods and entertainment. If the seller cannot do that, e.g. because their margins become negative, they will just stop doing business (in the US or entirely).

The other end of the spectrum is stuff people cannot do without, in which case the seller has no incentive to lower their margins because their customers don’t have a choice. Then, tariffs are entirely paid by the buyer.

In reality, everything is in between and accurately estimating how much everyone will be paying is very difficult. What we can predict with certainty is that prices can only go up, and that some businesses will fold because they cannot absorb the loss.

> why is the 1960’s the right target?

Realpolitik. Proper Nordic levels of (lesser) inequity is not likely in the USA. But selling the nostalgia of our '60s era prosperity might fly.

> if the Gini coefficient is calculated pre-tax

Firstly, then pick a different different metric. Gini coefficient is merely the most familiar.

Secondly, you asked about proper income tax rate. In my pithy reply, I implied outcomes are more important than implementation details, but slap fights (like this one) about those details are used to distract. (I think the kids today call that "bike shedding".)

Also, I did not explicitly state that measures of wealth distribution is the central issue. I regret the omission.

While I have your attention: How do you think our tax regime should be structured?

Feel free to link to any prior explanations (posts) I may have missed, so you don't have to repeat yourself.

> The attack methodology involved a particularly sophisticated approach. Attackers inserted a base64-encoded payload into an install script, causing secrets from affected CI workflows to be exposed in workflow logs.

What? How is that sophisticated? Who wrote this?

I still don't understand how we got to this point where CI/CD pipelines are built from random shit on the internet. I remember people being worried about packages in the system package manager curated by a (relatively) small set of trusted project maintainers. Now we're pulling in garbage written by who knows, under security guidance of nobody. At least the Arch Repo has a procedure and a trust network.

Every time I have to use GitHub actions and it recommends me using some "community" action I can't do it. I just know it's written by some 12-year old on spring break.

Here's how 66% compares to the trivial predictor: "pick the team with the higher win rate and flip a coin if they're equal" gives you 64% for the 2024 season I just tried it on.

I'm not even considering home/away, let alone win margins, recent form, strength of schedule etc. I'm almost amazed this model couldn't make any use of them.

> If you think estimating 1e-1000 is a problem, then estimating 1e+1000 shouldn't be.

They're both problems. If you want to estimate 1e1000 via sampling individual points, then you need at least that order of magnitude of samples. If all of your data points fall in one class, then it doesn't matter what you're trying to calculate from that.

As I said: "If you're inverting the ratio we're estimating, then instead of estimating the value at 0, we're estimating it at infinity (or, okay, if you want to use Laplace smoothing, then a million, which is far too low)."

Technically you can live forever in a universe that is completely empty, it'll just be a lot of cold dark nothing for eternity.

Living forever is such a strange desire, considering that complex life has existed on earth for just a fraction of the time it has existed, and humanity even less than that. I recommend watching the Kurtzgesagt video called All of History in one hour (https://www.youtube.com/watch?v=S7TUe5w6RHo&t=3670s). It displays all of earths history in one hour, and humanity is merely a few seconds of it.

Earth is ~4.5 billion years old, that's 4500000000 years, and in 1300000000 years it will be uninhabitable by humans, and in another 4.5 billion years (roughly 3.2 billion years after becoming uninhabitable) it will be engulfed by the sun.

Assuming humanity manages interstellar space flight you could possibly escape earth and live somewhere else until that also dies, but in case it is not practical or possible, you get to enjoy 3.2 billion years of literally choking and being burned alive on earth.

Assuming you did escape earth (or you're immortal so escaping doesn't matter) In 1000000000000 years the last star will be born, and in 100000000000000 years the last star will die out.

You now have an extremely long time to enjoy suffocating in hard vacuum with your body being boiled by the low pressure, and all in complete darkness until the heat death of the universe occurs in roughly 10000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000 years

I was a bit disappointed, even know there is no reason I should expect much in this space

- Tennis clip => ball is strongly unsynced with hit

- Dark mood beach video, no one in the screen => very high audio mood, lots of laughter like if it was summer on a busy beach

- Music inpainting completely switching style of audio (e.g. on the siren)

- "Electronic music with some buildup" : the gen just turns the volume up ?

I guess we have still some road to cover, but it feels like early image generation with out of touch hands and visual features. At least the generation are not non-sensical at all

I had a related, but orthogonal question about multilingual LLMs.

When I ask smaller models a question in English, the model does well. When I ask the same model a question in Turkish, the answer is mediocre. When I ask the model to translate my question into English, get the answer, and translate the answer back to Turkish, the model again does well.

For example, I tried the above with Llama 3.3 70B, and asked it to plan me a 3-day trip to Istanbul. When I asked Llama to do the translations between English <> Turkish, the answer was notably better.

Anyone else observed a similar behavior?

I always try to break out of local optimas I'm in and asking AI to give me other options/insights or even disagree with me. At the end we are steering the wheel and "amplifier" made sense to me.

I'm wondering how an "aggressive" button would look like in an AI, asking it to be less confirmative. Although I guess it will piss some people off since most of the times I just want a direct answer and get on with my code/life.

There are multiple theories that focus on different ethiologies of depression. Besides brain networks, early life adversities, sleep disturbances and the now obsolete monoamine hypothesis I read about the inflamation hypothesis. On a higher level that ties into all the other theories quite well and I don't oppose it. But there has been research into TNF-a, IL-6, IL-4, COX-2, and so on. We know there is inflammation, but we don't know where it starts and why. SSRIs are antiinflammatory in general, but why? Is this a downstream effect? Where is the original target we want to hit?

All those possible targets need to be verified by actual treatments. Treating the increased diabetes type 2 risk in depressed people is still advantagous but won't help the depression much. It's like changing tires on a broken car. Pushing is easier, but won't run by itself.

> But the processing fee for customs is usually 20-40 USD. Which can exceed the cost of the package in the first place.

It depends on who you are buying from. This is the order of magnitude of the fee if you let the shipping company handle it. It is extortionate and they do it because at this point buyers don’t have a choice if they want their stuff.

Companies that are used to dealing with foreign customers handle taxes themselves and don’t charge processing fees.

I read Being and Time recently and it has a load of concepts that are defined iteratively. There's a lot wrong with how it's written but it's an unfinished book written a 100 years ago so, I cant complain too much.

Because it's quite long, if I asked Perplexity* to remind me what something meant, it would very rarely return something helpful, but, to be fair, I cant really fault it for being a bit useless with a very difficult to comprehend text, where there are several competing styles of reading, many of whom are convinced they are correct.

But I started to notice a pattern of where it would pull answers from some weird spots, especially when I asked it to do deep research. Like, a paper from a University's server that's using concepts in the book to ground qualitative research, which is fine and practical explications are often useful ways into a dense concept, but it's kinda a really weird place to be the first initial academic source. It'll draw on Reddit a weird amount too, or it'll somehow pull a page of definitions from a handout for some University tutorial. And it wont default to the peer reviewed free philosophy encyclopedias that are online and well known.

It's just weird. I was just using it to try and reinforce my actual reading of the text but I more came away thinking that in certain domains, this end of AI is allowing people to conflate having access to information, with learning about something.

*it's just what I have access to.

I've read similar projects that use two lasers for microscopy [1]. They build them and used them to get images of cells. So I don't doubt of the general theoretical idea.

The devil is in the details. Can it run in open air or the concentration of argon is too low? Can it get enough brightness if you plug it in a standard electrical socket? How safe is it? [2] How many strong lasers escape the device? Does dust cause problems? Does it need a filter and a fan, or you need to enclose it to get clean enough air? How big it is? A tabletop device? Can it be shown to a thousand of people for an big event?

Perhaps you can get more traction here with some diagrams that show how it works without revealing all the secret details, but a text only explanation is too boring for the general public.

Anyway, I don't expect that this get many upvotes until you have a working prototype and some photos that shows it working.

[1] I think it was a German research team that also do confocal and 4pi microscopy. It was a long time ago, so I don't remember the details.

[2] A long time ago, I used an optical table that we shared with another experiment with a green 5W (5mW?) laser pointing to me and barrier in the middle and pipes and a lot of equipment. So it was safe, but just in case, never duck to pick stuff from the floor.
