I can only speak to my experience, certified devices by the largest firms will mostly not interoperate (fails around authN).

Apple: Keeps Thread credentials locked to HomeKit's border routers.

Google: Shares some credentials, but only within Google Account environment.

Amazon: TBD, but their Matter implementation is mostly cloud-tied.

Samsung: Hybrid approach; still best when used inside SmartThings, their 1.4 update seems to support for joining existing Thread networks. Still have to test it.

So, even though Thread theoretically allows full interoperability, no vendor wants to be reduced to a dumb router in someone else’s ecosystem.

there is no easy way to bridge Apple Thread to Home Assistant or Google Thread, even though it is theoretically supposed to be possible from a protocol standpoint.

If you have such solutions, let me know, because I would take full advantage of it, and will regale your contributions in multiple home automation threads.

The algorithm for instagram from my experience does push more content towards you related to your interests including your challenges. It just depends if that content makes your challenges worse or not.

For example, if you're having relationship challenges, it pushes more content related to that, of which that content can do more harm than good due to misinformation etc. It can also paint the situation in a good light or a bad light, it can help you heal but it can also help you shift blame to something else.

No takesies-backsies, Anna Lindsey Halligan! :-D

I don't get it. The Trumpsters play it like it's already a dictatorship. You can't threaten the press like this so soon. That only works when you have a firm grip on power and a credible history of jailing and exiling journalists.

It's like she watched Hegseth drunk texting in Signalgate and thought, "which journalist could I add on Signal".

This is important. The mechanism doesn't really work the way you want most of the time. I occasionally see a claim that you can power a carousel with this method, but it doesn't work. You would have to have the cable go out and around the carousel structure, and then into the top. And the cable would still move relative to the ground and the carousel.

You could, in principle, have a totally internal system, but with arms that grab and release the cable at intervals so that the looped portion can pass by them. You could arrange the timing so that electrical contact is never lost. But you are still making/breaking contact and it starts to lose some apparent advantages compared to a slip ring.

That's not to say it isn't still useful for some purposes, like maybe a radio antenna that isn't too impacted by a cable moving in front on occasion. But it doesn't eliminate all uses for a slip ring.

> raising the peso/dollar cross is effectively strengthening the currency against all other currencies.

If the peso rises against all other currencies, the dollar paying for it must fall against them, not as much but the dollar falls - at least relative to the movement it would experience without the purchase of pesos.

> Since the USD is one of the core currency crosses and is at the base layer of the financial system,

Abracadabra isn't an argument.

Hey, by all means go ahead - my personal reasons for doing it this way;

- Self contained dependencies managed for me by the maintainer of the image.

- I already run docker and keep all my configuration in a git folder that is structured in a way my brain works

- I already run watchtower which updates container for me automatically

- Other containers can use this container to send mail

- sendmail.cf scares me.

- filesystem isolation if it gets pwned

I grew up in communist bloc, finely oppressed by russians with their military bases all around, ready for nuclear WWIII that never came.

Peanut butter isn't something I ever saw before being adult and well into 90s, it simply wasn't a thing, I guess evil capitalist invention with the only goal to subvert our fine communistic paradise, like ie Star wars movies. Raw peanuts were frequent though, I guess one of very few things that actually made it through very badly functioning central planning and wasnt stolen by aparatchicks and collaborants for themselves. Never ever met a single kid having any sort of peanut allergy during growing up, never knew its a thing. I recall one or two with asthma, hay fever and thats it. But same could be said about any form of mental diseases/issues for whatever reason, anxiety, adhd variants and so on... either ignored, undiagnosed or really on much lower levels, dont know.

Kid misbehaving? A fine smack or some other physical punishment settled things at least in primary school. Then things started to change a bit till they overcorrected these days.

Depends entirely on the runtime.

If your GC is a moving collector, then absolutely this is something to watch out for.

There are, however, a number of runtimes that will leave memory in place. They are effectively just calling `malloc` for the objects and `free` when the GC algorithm detects an object is dead.

Go, the CLR, Ruby, Python, Swift, and I think node(?) all fit in this category. The JVM has a moving collector.

FOSS effort to bring live pixel art to microcontroller-driven displays, such ESP32 projects with LED matrices or LCD/OLED modules. This is for:

- Makers: Get art that looks awesome on low-res, download firmware

- Pixel artists: Reach real-world displays, gain points and badges

- Everyone: Enjoy free art & community, even if you don't own a display

At high level, the project seeks to combine an MQTT broker for live updates (new posts), a lightweight free & ad-free social media experience (comments and likes only), a self-hosted approach to storing the artworks, and MCU firmware to turn any display into a web-connected pixel art player.

Join us! It is a lot to build and this is all just for fun & love.

the issue isn't recognizing malign influence within your current organization... it's an issue throughout the entire industry, and I think what we're all afraid of is that it's becoming more inevitable every day, because we're not the ones who have the final say. the luddites essentially failed, after all, because the wider world was not and is not ready for a discussion about quality versus profit.

It’s not like fencing off part of the sidewalk. It’s like having a building next to that sidewalk with a door. The fact that the door is easily accessible doesn’t mean everyone is welcome to come in. If the door is open that’s generally how it is. If it’s locked, even badly, entering would be trespassing. If it’s locked with a button that unlocks it, and the button says “by pushing this button you agree to the following terms,” well, that’s hard to say.

Does qemu make an effort to preserve backwards compatibility with its cli? Because I have distinct memories of getting caught by them changing the way multiple parts of their command line work.

But in this case, my suggestions should be fairly backwards compatible; retaining the default of BIOS but adding a simple `--firmware uefi` option would change nothing for existing users, and even defaulting to `--firmware uefi,bios` should be mostly compatible since it just tries UEFI and then promptly falls back to BIOS.

It depends on the SSD, I may say.

If we're talking about SATA SSDs which top at 600MBps, then yes, an aggressive application can make itself known. However, if you have a modern NVMe, esp. a 4x4 one like Samsung 9x0 series or if you're using a Mac, I bet you'll notice the problem much later, if ever. Remember the SSD trashing problem on M1 Macs? People never noticed that system used SWAP that heavily and trashed the SSD on board.

Then, if you're using a server with a couple of SAS or NVMe SSDs, you'll not notice the problem again, esp. if these are backed by RAID (even md counts).

> For Eckmann, the new work is a showcase of how rich mathematics can be even in a field as well-trod as the study of rotations. Tlusty says that it could also have practical consequences, for instance, in nuclear magnetic resonance (NMR), which is the basis of magnetic resonance imaging (MRI). Here, researchers learn properties of materials and tissues by studying the response of quantum spins inside them to rotations imposed on them by external magnetic fields. The new proof could help develop procedures for undoing unwanted spin rotations that would interfere with the imaging process.

> I had an absolutely disgusting thought today: Robinhood should offer parlays. Sell customers a call option on multiple assets. For example a call option to buy Apple at $250, NVDA at $190, GameStop at $25 and Bitcoin at $120k, but only if ALL of them are in the money. Robinhood could buy offsetting calls on each individual asset, then sell the parlay “bundle” to retail. Risk-free profit for Robinhood, and their customers would love it.

I don't see how this is risk-free - surely it involves some opinion on the correlation between the assets?

I been thinking about this too as I am looking to buy my first EV.

With a ICE you look at the odometer when purchasing, outside of that you don't actually know whether that reading and the state of the engine gives you less range, less power or an indicator of parts failing.

With an EV, similar to other electronic devices, you get an actual number that tells you the life of the battery which allows you to infer anything you like in terms of what that would mean for the life of the vehicle.

It will take time for people to know the true life of an EV in the second hand market. The general public are skeptical of EV's, so it makes sense they would be all the more skeptical of them second hand.

> when we can accomplish something there

Realistically, the accomplishment will be a resource grab. It's not scientific. The moon will eventually be carved up by (disputed) territorial claims, like Antarctica. Countries will need to maintain bases to back their territorial claims. Eventually the claims will turn into mining rights. The resources are valuable for being in a reduced gravity zone. All those juicy water containing craters at the Lunar poles... [1]

>Turns out that LLMs learn a lot better and faster from educational content as well. This is partly because the average Common Crawl article (internet pages) is not of very high value and distracts the training, packing in too much irrelevant information.

>The average webpage on the internet is so random and terrible it's not even clear how prior LLMs learn anything at all. You'd think it's random articles but it's not, it's weird data dumps, ad spam and SEO, terabytes of stock ticker updates, etc. And then there are diamonds mixed in there, the challenge is pick them out.

> At that point why not abandon databases entirely and use a key-value store?

Because there is a schema, it's just a dynamically evolving one, and also, presumably the rest of your system depends on the relational DB, so why multiply your dependencies unnecessarily?

> You're not even talking about traditional relational databases anymore.

There's nothing non-relational about the schema I've outlined, it matches what the domain requires with less noise than 400 nullable columns.

Congrats for only reading the header ;) It's actually a pretty decent OpenGL 1.1 software implementation, obviously not complete and spec-correct though. It's more like those MiniGL drivers back in the day, implementing just enough of the spec so the game can run ;)

In a similar way, this implements just enough so Raylib's OpenGL backend can run! It was done so you can use the library without external graphics dependencies if you really want to.

> At most the number of subqueries increases by the number tables.

Fair enough. Application logic will want to access the data as a flat record, but that could be handled through getters. We have views which are also used by customers and our reporting tool, but the customers we're moving to API access and reporting could probably be done with something better if starting from scratch.

> That's a fairly small amount of data, I don't really see an issue here.

Well it turns 100k inserts into tens of millions. On tables where users need to work without slowdown while this is going on.

It probably works if you throw enough hardware at it, but currently we get by with quite modest DB hardware.

That said, how do you create compound indexes over these fields? Say you need to index one date and one varchar column? Such demands can arise down the line, often hard to predict up front.

My point is that the letter of the First Amendment and the spirit of the First Amendment are at odds when faced with modern day reality. Between government and corporations, and being fined, vs being put in prison, it's all up for debate. We can look at the letter of the First Amendment and twist and turn it to come to a definition that the courts can agree on, but stepping back from that, the bigger picture is the people are trying to speak and that this entity that isn't the government, is restricting that, with downstream effects. You're right that the First Amendment doesn't apply to app stores run by a private corporation. It's still a restriction on speech by a large organization against an individual, and the freedom of speech gives people the right to complain about it.

You can't both talk about "professional shorts" and use it as an argument against somebody who is not a financial professional. This argument is invalid because not every person who is skeptical about current AI companies' perspectives is willing or able to become a professional short just to make a point on it. One can have a perfectly valid argument and still not be a professional short based on it.

This. A quick scan of the wikipedia page for diamond material properties suggests you are very correct. It appears very chemically inert, with some outstanding exceptions: "Resistant to acids, but dissolves irreversibly in hot steel"

https://en.wikipedia.org/wiki/Material_properties_of_diamond

Also, removed/liberated particles of Diamond from the workpiece which failed to fully chemically dissolve into the slurry would then contribute to the abrasive in the slurry. If the slurry abrasive was not also diamond, then that could lead to some serious scratch/gouging of the work surface.

Perhaps not insurmountable, but wow, that sounds like a stiff challenge, especially when accounting for cost.

I wonder if diamond would be machinable with a dry (plasma) etch instead? I am purely speculating here, this is far out of my wheelhouse. But SiO2 is already very chemically inert (though considerably softer vs diamond), but manufacturers regularly dry etch it.

Capitalism is incredibly efficient this way and it really should be appreciated as being such an advantage. I wonder if it’s not a free advantage though. I suspect there’s a risk that it might diminish the ability to accomplish projects that aren’t compatible with capitalism. Ie. ROI isn’t sufficiently short term, ROI is socialized, no ROI at all, excessive risk.

An open question as I really don’t have an answer either way: what’s the last mega project the U.S. succeeded in completing that wasn’t directly tied to a short term business plan? Something for future generations or a major environmental project or a transportation or infrastructure project, etc.

> It feels like 100x slowdown.

Yup, this is a thing. It happens because file-backed program text and read-only data eventually get evicted from RAM (to make room for process memory) so every access to code and/or data beyond the current 4K page can potentially involve a swap-in from disk. It would be nice if we had ways of setting up the system so that pages of code or data that are truly critical for real-time responsiveness (including parts of the UI) could not get evicted from RAM at all (except perhaps to make room for the OOM reaper itself to do its job) - but this is quite hard to do in practice.

What if my reason isn’t, “I like typing code” but instead, “we don’t need more Googles doing Google things and abusing privacy.”

Then personally the whole thing is spam.

Regardless of what the reasons for and against Llms maybe doesn’t obfuscate that the primary use case for generated content has been to scam and spam people.

That spam scam can be simply getting people to pour their personal private info into an Llm or it can be ads or a generated lie. Regardless it’s unwanted to a lot of people. And the history of that tech and attempt at normalizing it are founded in spam techniques.

Even the gratuitous search for AGI is spammed on us as these companies take tax payer money and build out infrastructure that’s actually available to 0% of the public for use.

Yes, but it's not great for it to be an optional config option. Trivially easy to use data exfiltration methods shouldn't be possible at all in a tool like this, let alone enabled by default.

I want to recommend ppl to try this out and not have to tell them about the 5 different options they need to configure in order for it to actually be safe. It ends up defeating the purpose of the tool in my opinion.

Some use cases will require mitmproxy whitelists as well, eg default deny pulling container image except matching the container whitelist.

I think a big difference is when someone is pretending to be all about something else and tries to sneakily market to you. One thing is getting a free water bottle with an ad, another thing is when someone is inviting you to a "party" with free food and drinks and it turns out to be a MLM "party".

Netflix is giving away free water bottles (I hate them, but I use their fast.com super often to test the speeds), another is pretending to be a blog post, but actually being an ad (if that was the case here). You just feel lied to. You cannot take anything seriously you read there, as it will probably be super biased and you cannot get your time back now.

2. Actually, no, I will fight you on this: Unless you're actively trying to break them, docker, nix, flatpak, or any of their ilk will trivialize updates and give you guaranteed uninstallation and going full container will absolutely let you lock down exactly what an application is capable of touching or leaving behind (so, easy with podman/docker, varies with flatpak).
