> There is no real protection on card readers (most use Linux with a small shitty password). The protection comes from the contracts and regulations between the shops and the banks.

Wait wait wait... Aren't these EMV cards smart cards using the Java smart card technology? I thought these were heavily using encryption, including PKCS.

They're using challenge/response protected by the PIN no!? If I am not mistaken if you insert a card in a totally compromised reader you cannot clone the card: that alone is already quite an amazing feature compared to where we're coming from with the magnetic stripes ones (and the date to sunset for good magnetic stripes in the EU has already been set IIRC).

A fully compromised reader could trick you in stealing your PIN (so that an accomplice could then later on steal the card physically) and a compromised reader could also trick you into signing a 2 EUR transaction while it's actually wiring 2 000 EUR out of your account but I think that's about it!?

It comes to this: either the card can be cloned from a compromised reader or it cannot. I don't think that someone inserting it's card and getting its PIN intercepted means: "Bad guy can do countless transactions for days on until the account is empty".

If I'm right, that's a very far cry from "protection comes from the contracts and regulations between the shops and the bank".

AIUI a compromised reader can fake one big transaction or maybe a few transaction in quick succession but as soon as the owner pulls its card, they cannot do anything anymore?

It's pretty much always cheaper than going to cloud services.

The biggest thing I hear otherwise is "but salaries!". Okay, but you're just replacing your sysadmins with AWS devops people, who I can't imagine are cheaper.

Cloud isn't simple, it's very complex. You need just as many people and just as much knowledge to make it work.

I took it seriously as a student. I remember during a no-book take home exam having forgotten some stupid little fact, and thinking “damn it would be such a little thing to look it up in the textbook” and feeling so much shame about even considering it, specifically because I had to handwrite an honor pledge on my work. (I didn’t cheat, by the way.)

The Solidgm D5-P5336 122.88TB SSD is $12,000

$12,000 * 1000/122 is about $98,000.

While expensive these drives would be so much denser than magnetic drives that they would save a LOT of data center room and probably prevent many new data centers from having to be built so might be cheaper in long term total cost of ownership.

Thanks for the feedbacks! The local hub model makes a lot of sense, making it easier for folks to contribute tools without the day-to-day management. Its true that this is not for everyones tho but some folks are happy to rent out tools and connect with neighbors, others would rather drop them off once and forget about it. We're exploring ways to support both but the local hub idea fits that really well.

The FE us using React and styled-components. We're not using components-library, pretty much everything is customized for our needs.

>Is this really not common? I constantly see internet claims about how it would cause violent uproar from evil land owners if we taxed land value, but as a land owner I can tell you it’s already happening.

LVT does exist in several places in the world but it's usually around ~3-5%. Unusually for most taxes, it can be raised probably to almost 100% without any economic ill effects, but the land ownership classes would raise absolute hell.

This is how their propaganda mouthpieces reacted in the UK at the proposal: https://archive.ph/6gtRC

>That would be awesome for the people with giant, new construction houses around me but not so good for those of us with smaller, older construction buildings

Not sure why you feel specifically singled out, but ok.

It would be most awesome for people living in high density apartments and least awesome for people who live in crappy low density housing in high value areas which ought to be converted to apartments.

>It would be really bad for the old people living out their final years in their modest old houses which need a lot of repairs (and therefore have low structure grades in the tax system and low structure taxation).

Only if you pretend that those people can't move, and they would. Those people would just downshift to apartments in response - this used to be a lot more common anyway - my grandmother did this.

If you want somebody to feel sorry for, though, feel sorry for old people living out their final years in rented accomodation. If you rent, by definition, you have to pay LVT (to a private landlord), and if you can't pay - to the street for you.

A fun thing to make. I made this in the high school chemistry room after school. Filter paper with some iodine crystals, pour some ammonia over and wait for it to dry (as I recall). I am not sure where I learned about it. Often my dad, who was a chemist then, would tell me little tricks like this. (He also turn me on to slathering a small amount of potassium permanganate with glycerin.)

Anyway, I was walking with it after I made it (when it was still damp and in the filter paper) and I accidentally dropped the filter paper in the school hallway. I picked up what I could (I suppose I should have gone back and mopped it up).

It was fun, the small explosions, like tap shoes clacking, when it was dry and walked upon. (Too bad it left brown stains on the linoleum.)

I was fortunate to have not had a large quantity dry. It can be pretty dangerous in large amounts I am told.

I didn't find the images relevant to the article - they seemed to just be filler to avoid it seeming like a mundane wall of text - but I just ignored them & didn't find it hard to read as a result?

I can understand it might be difficult to understand the context of some set descriptions without having seen the show but I think that would also be true with relevant still images as you'd still lack character & narrative context.

Honestly can't see how they could've formatted the article any better than they did. Seems fine.

They let it be. The decision is many-fold correct:

1) hobbiests that are obsessed with self-hosting can use it -- tailscale will never see a penny from them anyways

2) some businesses will consider headscale as an escape hatch de-risking if tailscale were to be purchased out by an extortionist (like broadcom's acquisition of VMware)

3) It signals they are doing business in a position of strength: businesses don't buy software, they buy solutions to problems

It's a lot, but you're right that the more realistic scenario is just running an existing open source model - sadly those are trivial to misalign

So we better have SOTA clouds: people don't update computers for months and as Bredolab shows - their GPUs are up for grabs

Ideally and int. org. will do it but they are slow and countries don't cooperate enough, so a startup is more realistic

Maybe just give it a go on OpenAI?

An example on how to train (a presumably small) model to call a get_current_weather function: https://platform.openai.com/docs/guides/supervised-fine-tuni...

It's not such a sexy subject, it's mostly done by companies to reduce costs, which is maybe why there is not much written about it.

> the savior of the Star Wars brand

I think Rogue One is the best Star Wars ever and Andor is in the same vein. But.

The savior of the Star Wars brand is always going to be the latest lightsaber-fest for 10-year-olds. That creates customer loyalty that will survive forever. Those kids then grow up and get to bitch about the new lightsaber-fest, and to fawn over the artsy drama.

The only country pushing hot war your way is Russia and how is it going to get there with most of its tanks destroyed and its air force on the way out?

I guess they could send cruise missiles into children's hospitals and stuff in the usual Russian way but that would be a very bad idea for them really as they are struggling against Ukraine attacking NATO territory militarily would be another level.

Of course they'll hit us with propaganda and politician buying. But such is life.

Naive question, are there good tutorials/places that teach us to implement RAG and fine tune a model? I don't know if it's even feasible. At the moment I create AI workflows for the company I work at to (semi-)automate certain things. But it's not like I could fine-tune Claude. I'd need my own model for that. But would I need a whole GPU cluster? Or could it be done more easily.

And what about RAG? Is it hard to create embeddings?

I'm fairly new with the AI part of it all. I'm just using full-stack dev skills and some well written prompts.

I actually work in close relationship with hospitals, there is a lack in quality of life for doctors, most of their salary is extremely taxed, they are extremely overworked and with very bad working conditions.

They often move out of the country, and the ones that remains are often not the better ones.

But yeah, its less expensive, unless you factor all the things that are not reimbursed and the wait times.

I'm loosing karma, I guess I can't express my data point freely.

No one is claiming that LLMs invented astroturfing, only that they have made it considerably more economical.

> You're just doing the bidding of corporations who want to sell ID online systems for a more authoritarian world.

Sure, man. Funny that I mentioned "web of trust" as a potential solution, a fully decentralised system designed by people unhappy with the centralised nature of PKI. I guess I must be working in deep cover for my corporate overlords, cunningly trying to throw you off the scent like that. But you got me!

If you want to continue drinking from a stream that's been becoming increasingly polluted since November 2022, you're welcome to do so. Many other people don't consider this an appealing tradeoff and social systems used by those people are likely to adjust accordingly.

I refer to the RP2xxx chips as "headless Amigas" because their PIO modules essentially function like Coppers: they are simple state machines that offload I/O functionality off the CPU.

I think there's a very strong future in emulation of achieving FPGA-like latency by using a Raspberry Pi Pico/Pico2 to emulate each of the target machine's subsystems/chips.

I have a pretty radical opinion that math education should be focused on building Computer Algebra Systems like Mathematica and Theorem provers like Lean with a heavy focus on visualization and practical applications. Taken to the extreme this could mean never doing paper math while being able to prove everything you learned in Lean.

I feel our current system's focus on endless manual calculations that seem so useless is boring and tedious and makes people hate math.

It's talking to a model over an API. Currently using Claude. Certainly would not be reasonable to do from scratch. The basic starting point to make a coding assistant is basically reading text from the user, feeding it to the model over the API, and giving it a couple of basic tools. Really the models can handle starting with just the ability to execute shell commands (with confirmation, unless you're braver than me), and from that you can bootstrap by asking it to suggest and write additional tools for itself.

If you accept this as true then you have to accept the United States Secret Service was criminally incompetent in failing to stop a single "lone nut."

I didn't realize this was up for debate.

From the article:

> Before they understood what was happening, the researchers first thought that water was simply condensing onto the surface of the material due to an artifact of their experimental setup, such as a temperature gradient in the lab. To rule that out, they increased the thickness of the material to see if the amount of water collected on the surface would change.

There's a temperature gradient in their lab setup. i.e. one side of the material is cooler than the other side. This is where I extrapolated that you can increase the performance of the material by bleeding the heat into the Earth.

Oh wow! Growing up my chemical engineer uncle would come out on the Fourth of July and dump a bucket of stuff on the road in front of his house. A while later when it was dried he'd have us roller blade and skate board down the road to setup all the little explosions. It was a total blast. He refused to tell anyone what the compound was, but assured us it could be easily made. It has to be this stuff.

It was irritating to a specific brand of nerd who valued "doing it first" over "doing it right". They were a fascinating sideshow back then, if not a little irritating themselves. To see someone write this in 2025 is like learning about the Japanese holdouts after World War II.

Are you sure these weren't just plausible guesses at file names? It's just a hallucination.

I asked it for the list of files in some public repositories (which are definitely in the training data) and it gave me a plausible-but-wrong list of files. It can't remember that kind of detail.

It didn't start with the intent of being a service; I started with it because there were a number of things that Copilot or tools like Claude Code doesn't do well enough that annoyed me, and spending a few hours was sufficient to get to the point where it's now my primary coding assistant because it works better for me for my stack, and because I can evolve it further to solve the specific problems I need solved.

So, no, I'll keep doing this because doing this is already saving me effort for my other projects.

> This was most probably supervised by NATO, there's no other way.

Technically speaking, this is a hobby-level undertaking. A model airplane club could "supervise" such an operation.

Skills needed:

1. Build a mechanism to remotely open the roof of a cargo container.

2. Add a GPS tracker to the container to follow its position.

3. Build a signal repeater that uses commercial cellular service to provide connectivity to the container.

4. Tape explosives to toy drones and wire their detonators to a drone function that can serve as a trigger.

Which one do you reckon would be too difficult for a group of 16-year-olds who know their way around Arduino?

Yes, the overall narrative of the prequels was good and very promising. It's so unfortunate that they turned out to simply be shockingly bad as movies - "clumsly" really doesn't describe how stodgy and badly put-together they were.

I honestly hope Disney will eventually remake them from scratch, with the excuse that FX have progressed dramatically since then. They could even reuse McEwan, considering he's supposed to be an older character already.

Actually, putting your card on your phone is a better protection against theft : they cannot be used without biometric identification, can be remotely revoked and you can still keep your plastic cards as backup.

I could easily live without it and I wouldn’t even consider it to be an important gesture for my next phone but it’s pretty useful when you have it.

Also, idk for Android but on iPhone it’s faster than plastic cards and more secure.

But I hope plastic cards are there to stay because that’s yet another thing locking us into the iOS/Android duopoly.

I was actually hoping for 4 seasons. Considering how they put 4 different, excellent stories in season 1. Season basically told a single story (the Ghorman massacre) spread out over 4 years. There were many moments where I'd hoped they'd dive a bit deeper into some other aspects, like what would become of the Maya Pei Brigade, the stolen TIE Avenger, other missions where we see Andor grow into the expert spy that he's clearly become. And of course more about how they bring the various parts of the rebellion together, the move to Yavin, etc.

I think there was more than enough room to fill at least another season. Maybe two.

But hey, I'm more than happy we got this much.

Oh, a ton of reasons. But for me, the big one is that open source work is maybe the single strongest signal I have to the rest of the Internet-faring world that we like to cooperate in this vast, iterated game that is society. That's not not true of paid work, but spending your own free time building cool things other people like and then giving it away is just a whole 'nother level.

You're not ever going to rationally convince me that ICE (or, CBP in this case) as it stands today is doing anything positive for most people in this country. And the folks it does benefit benefit from other behavior I find repugnant, like temporary work visas paying well under a livable wage, and media personalities who make money by driving easily-manipulated people into a frothing rage.

Not that I ever expect the people baying for blood to care one iota for other people's perspectives. It must be such a thrill to think you're being invaded by your neighborhood line cook.

I agree with everything you said up to "Nothing in those definitions is capable of expressing the concept of having perceptions (consciousness)".

If you think the universe is computable, and you think that you exist in the universe, and you think that you are conscious, don't you think it follows that consciousness can exist within mathematical structures?

This is an extremely bad method of storing text data. Video codecs are not particularly efficient at compressing QR codes, given the high contrast between the blocks defeating the traditional DCT psychovisual assumptions of smooth gradients. There is little to no redundancy between QR code encodings of similar text.

You'd probably have a smaller database and better results crunching text into a zip file, or compressed rows in a sqlite database, or any other simple random-access format.

Ember did something like this but it made writing Ajax endpoints a giant pain in the ass.

It’s been so long since I used ember that I’ve forgotten the terms, but essentially the rearranged the tree structure so that some of the children were at the end of the file. I believe it was meant to handle DAGs more efficiently but I may have hallucinated that recollection.

But if you’re using a SAX style streaming parser you can start making progress on painting and perhaps follow-up questions while the initial data is still loading.

Of course in a single threaded VM, you can snatch Defeat from the jaws of Victory if you bollocks up the order of operations through direct mistakes or code evolution over time.

Some musicians still like to play instruments -- for them and their listeners, ITB production is seen as a cheat and not real musicianship -- and for them the lack of a stable MIDI clock on today's hardware absolutely does matter. A trained musician can feel time difference as small as 1 ms. Any latency or jitter greater than that and a perfect track could be ruined.

As an aside, all-digital workflows take the joy out of music being made in the moment, by ear and by feel. There is no replacement, for example, for a professional sound engineer adjusting a mix strictly by the sound in their headphones and the feel of the sliders under their fingers.

> Do you think the universe is not computable?

Yes, definitionally not, the universe isn't an abstract object let alone one in the shape of a function.

You might, in principle, be able to precisely predict the future of the universe given perfect information using a precise model of the universe. That model, a mathematical function, would be computable. It would be accurate to say that the model describes the universe, but not that the model is the universe.

The thing about mathematical structures is that they are concepts, not things, I feel confident in saying that concepts aren't conscious.

Oh I see. I'm not familiar with the model used by Workbench and how it differs exactly.

(edit: and to be clear, I did read the article and see what it said, but without more detail I'm not 100% sure what it really looks like in practice, and why it would be less likely for applications to have situations where they become unresponsive.)
