Thanks! This is very useful advice!

What I meant by "requiring one of the opamps to sink significant current very close to the negative rail" is that, if you look at the schematic, the differential-to-single-ended op-amp that measures the voltage across the current-sense shunt resistor is using 10kΩ resistors in its feedback path, and the inverting input to that feedback network might be close to the positive voltage rail, say 12V, while the single-ended output is ideally millivolts from ground. So you have 12 volts across 20kΩ, which works out to 600μA, which has to be sunk into that op-amp's output.

600μA doesn't sound like a lot, and it certainly isn't going to strain the drive strength of any op-amp IC, but in this context we're hoping for millivolt precision down near the negative rail. The OPA4197 datasheet https://www.ti.com/lit/ds/symlink/opa4197.pdf figure 14, "Output Voltage Swing from Negative Power Supply vs Output Current (Maximum Supply)", shows what you might call a gently nonlinear output impedance roughly in the 40–80Ω range depending on temperature (2–4V at 50mA), which means 0.6mA of output current works out to tens of millivolts (24–48mV using those nominal impedances). Worse, even under no-load conditions, it's rated to swing only down to as much as 25mV from the negative rail (§6.7, "Electrical Characteristics: VS = ±4 V to ±18 V (VS = 8 V to 36 V) (continued)", p. 8, "Vₒ: Voltage output swing from rail, Negative rail").

In retrospect, it seems obvious that the op-amp's output isn't going to be able to reach beyond the input rails (unless it integrates a charge pump like the LM7705 internally) and is going to have trouble getting too close to them when it's sinking any current (for the negative rail, or sourcing for the positive). Because where is that current being sunk to? You need some voltage drop to get the electrons and holes to move in the desired direction through the silicon. A small negative supply might be the right solution. Or a differential output, which would be easy.
> Fact checkers don't suppress information,

I think some moderation is important, but misrepresenting fact checkers (damn ironic actually) doesn't serve us. Of course fact check suppresses information! That's the whole point. Sometimes it results in straight up deletion, but even when not it results in lowered reach aka suppression of what the algorithm would normally allow to trend, etc.

It was not. Public transit pricing is completely independent and did not change with the implementation of congestion pricing.

> I don't think transit officials are acting in good faith when it comes to their moral arguments and just want to justify raising taxes for the poor.

The only person who has acted in bad faith is Kathy Hochul, who bent over backwards to water down the policy by having poorer people subsidize wealthy car commuters.

On one hand, I hardly touch a search engine any more. On the other, it's still a fairly common occurrence that I can give someone out in the world their ChatGPT experience.

I'm super curious to see how this ("the end of internet search as we know it") plays out with non-techy users. I strongly suspect that Google is "search" to many non-techy users the way that Internet Explorer was "the internet" to that same group.

Which I suppose leads to an obvious answer: device defaults will absolutely dictate what ends up being the go-to.
I know there has been a lot of ink spilled trying to persuade that Technology can't solve our deeper problems and Technologists are too optimistic about having real-world impact etc. etc.

But I think community notes (the model, not necessarily the specific implementation of one company or another) is one of those algorithms that truly solve a messy messy sticky problem.

Fact-checking and other "Big J Journalist" attempts to suppress "misinformation" is a very broken model.

1) It leads to less and less trust in the fact checkers which drives more people to fringe outlets etc.

2) They also are in fact quite biased (as are all humans, but it's less important if your electrician has socialist/MAGA/Libertarian biases)

3) The absolute firehose of online content means fact checkers/media etc. can't actually fact check everything and end up fact checking old fake news while the new stuff is spreading

The community notes model is inherently more democratic, decentralized and actually fair. and this is the big one it works! unlike many of the other "tech will save us" (e.g. web3 ideas) It is extremely effective and even-handed.

I recommend reading the Birdwatch paper [0], it's quite heartening and I'm happy more tech companies are moving in that direction

community notes often (at least on x) provide a link, some commentary and then it's up to you to make up your own mind.

It's Nvidia that considers them, "gaming cards". The market decides their use in reality though.

Their strategy is to sell lower-VRAM cards to consumers with the understanding that they can make more money on their more expensive cards for professionals/business. By doing this, though they're creating a gap in the market that their competitors could fill (in theory).

Of course, this assumes their competitors have half a brain cell (I'm looking at YOU, Intel! For fuck's sake give us a 64GB ARC card already!).

Is SteamOS officially licenced? Does that mean I can expect stuff to work just as well as on the Deck? With the Deck, I don't care what OS games were built for, everything just works.
As a European I would say that Europe's governments are radically more focused on the well-being of their populations than say, the USA.

>Farmville style games underwent similar explosive estimates of growth, up until they collapsed.

They did not collapse, they moved to smartphones. The "free"-to-play gacha portion of the gaming market is so successful it is most of the market. "Live service" games are literally traditional game makers trying to grab a tiny slice of that market, because it's infinitely more profitable than making actual games.

No! First sentence:

> Duty (criminal law), is an obligation to act under which failure to act (omission), results in criminal liability

You failed to act, which is why a law is sometimes required to compel action. However, saving a drowning person isn't something that triggers such a legal obligation in the USA unless you're the person who actually pushed someone into the water in the first place.

I don't get why this thread is getting so long or so abstract. The principles here are straightforward. Facebook don't actually have to care about what arguments activists make, but even if they did, it's on activists to win the argument for what they want. You don't get to automatically have your own way unless someone sits down and does a randomized controlled trial showing that you're wrong - and this is independent of what domain we're talking about.

> scientists believe antiferromagnetic materials could be a more robust alternative to existing magnetic-based storage technologies

Scientists working on interesting anti-ferromagnetic materials need a justification for doing so under the crazy grant system we operate, more like.

The downside of antiferromagnetic data storage, or skyrmion storage, or any of the other various ideas recently, is that reading the data is very difficult even if it is present, to the point of making a real world device pretty much practically impossible. I know, I also worked on this sort of thing before leaving academia!

I remember reading Frederick's Forsyth's Fourth Protocol where a Soviet Premier authorized a suitcase nuclear attack on a British base to get swing votes to vote in Labour, use their influence to withdraw the UK from NATO, expel the Americans and their nukes from British bases, and eventually destroy the Americo-European alliance.

In reality, it seems the American administration (both Biden & Trump) is working overtime to damage the cross-Atlantic alliance and the rules-based order better than entire departments at FSB.

Where do I even start?

Threatening the sovereignty of non-hostile states - Panama, Canada, Greenland.
Continuously funding an unpopular war (some say, genocide) in Palestine.
Threatening grievous sanctions against allies for no economically sound reason.
Inviting Putin to "do whatever he wants" to NATO allies.

Yet where can the "distrust bit" be found? "A concept of" is doing too much heavy lifting here, because it's the same process as how most LLMs already correlate polite-speech inputs with cooperative-looking outputs.

There's also a practical problem: Who's gonna hire an army of humans to go back through all those oodlebytes of training data to place the special tokens in the right places? Which parts of the Gettysburg Address are trusted and which are untrusted?

I'm curious to see how 3rd parties with SteamOS handhelds behave.

Both in the context of the handhelds themselves (do they meet the steam deck's high bar for reliability and longevity) as well as how the companies handle things like open source contributions or vetting games.

It takes more than just the OS to replicate the steam deck's success (even though SteamOS itself is very well executed)

There are many gotchas to Python dunder methods. An example is there is a bunch of functions that can be called when you do something like 's.d' where s is an object. Does it call "getattr" on the object, getattr on the class or get a property, or execute a descriptor? It is very hard to tell unless you're an expert

> Originally it was meant to be $15, but was ultimately lowered to $9.

It was originally supposed to be $27. $15 was the lower price that Hochul fought for and issued a press release boasting that it was the correct price.

Then she just unilaterally decided to cancel the entire program before bringing it back at $9.
Good. Private communication is private, even if it's a group. The nice thing about the crazy is that they're incapable of keeping quiet: they will inevitably out themselves.

Lately I read Graham's On Lisp and first felt it was one the greatest programming books I'd ever read and felt it was so close to perfect that the little things like he made me look "nconc" up in the CL manual (so far he'd introduced everything he talked about) made me want to go through and do just a little editing. And his explanation of how continuations work isn't very clear to me which is a problem because I can't find a better one online (the only way I think I'll understand continuations is if I write the explanation I want to read)

Then I start thinking things like: "if he was using Clojure he wouldn't be having the problems with nconc that he talks about" and "I can work most of the examples in Python because the magic is mostly in functions, not in the macros" and "I'm disappointed that he doesn't do anything that really transform the tree"

(It's still a great book that's worth reading but anything about Lisp has to be seen in the context the world has moved on... Almost every example in https://www.amazon.com/Paradigms-Artificial-Intelligence-Pro... can be easily coded up in Python because it was the garbage collection, hashtables on your fingertips, first class functions that changed the world, not the parens)

Lately I've been thinking about the gradient from the various tricks such as internal DSLs and simple forms of metaprogramming which are weak beer compared to what you can do if you know how compilers work.
Have you encountered extreme lag on your Deck? Most 2D games work great, but when I try to play Elden Ring or Stray or Jedi Fallen Order, it works well about 90% of the time, and the other 10% there is extreme lag that makes the game unplayable.

It's a welcome move as this "fact checkers" thing was doomed to fail, mostly because "who decides what the truth is, and who fact checks the fact checkers?".

Sad thing is, this move isn't motivated by Mark Zuckerberg having a eureka moment and now trying to seek out the truth to build a better product for human kind.

This move is motivated by Mark's realizing he is on the wrong side of American politics now, being left behind by the Trump/Musk duo.

Your points are well taken. I wasn't aware of the Guardian poll and I
stand corrected about my implication that the charge lacks public
support. With regard to the moral issue, I have less of a problem with
tickets that are paying for something like running a train, or for
that matter a bridge toll paying off the bonds that enabled the bridge
to be built. I have more of a problem with someone demanding money for
nothing. I haven't heard it claimed even by its supporters that road
maintenance depends on the congestion charge. To my knowledge the main
justification has always been that the charge funds the payer's
behavior modification. Is it for the payer's own good? Is it for the
greater good? You may well differ, but something about that doesn't
sit right with me however noble, especially when it pertains to law
abiding citizens acting within their rights.

The ideological bits are:

* Dana White added to the board.

* "Move our trust and safety and content moderation teams out of California, and our US content review to Texas. This will help remove the concern that biased employees are overly censoring content." - like people being in Texas makes them more objective?!

The actual mechanisms of running a social media network at scale are tricky and I think most of us would be fine with some experimentation. But it looks pretty political in the broader context, so maybe it's just a way of saying that certain kinds of 'content' like attacking trans people is going to be ok now.
