I have done multiple 10+ hour (although no multi day) road trips in an ev. It was fine. I had problems exactly one time and i was able to just go to a different charger a mile away.

All of the chargers I've used had apps, but they also allowed using a credit card, which seems like it would have solved your problem just as well. And that's already a solved problem, even if not every charging network uses it.
Yes. Also follow the chemistry, and follow the maths.

In certain situations, crossing the JNI boundary can be advantageous. When data resides in "native" memory, outside the Java heap, the coordination of concurrent execution logic can be handled in Java, while the actual execution occurs in C++ or Rust. In this context, the negligible penalty for crossing the JNI boundary once per 10 million rows pales in comparison to the substantial benefits achievable through C++ optimization or CPU-specific assembly.

Would this be a viable option for maintaining extra low earth orbits?
It's like an ion drive. Here's the steps:

1. Start with a metal rod.

2. Remove one atom from the rod.

3. Remove electron from atom.

4. Now that the atom is charged, shoot it out the back of the engine really fast using electrical repulsion.

5. Shoot the electron out the back (using a different pipe) so that the exhaust doesn't come back at you due to electrostatic attraction.

6. Now you have the rod, with one less atom. Repeat. A whole ton of times.

Steps 2&3 might happen simultaneously, not entirely sure the mechanism but generally an electrical arc is violent, it will spallate and ionize a few atoms here and there.

Not having a tank is huge, and the first ionization energy of many metal ions is far far lower than noble gases, which are what is commonly used in normal ion drives

The only way to reduce traffic without changing your routine is by packing more people in less space, i.e. public transit.
Maybe, but it isn't clear as if you do this and one system breaks the other system also has to be taken down for repairs. Sure you can put fiber in these tubes, but if the tube needs to be replaced you have to cut/splice the fiber inside. Likewise if a tube collapses (more likely to break the fiber than if it was surrounded by dirt) you have to do something about that fiber to get it out. So long term it could be worse to do this.

Note that we are talking about small tunnels here. A large tunnel that a human could walk in allows more flexibility.

Eh, I'd change the analogy.

AI is a bubble in the sense there isn't a direct path of put more money into research and get a better result. I'd almost argue we are spending money in the wrong areas.

The internet had clear and well defined steps for improvement. Although we can increase accuracy or whatever by 1-2% that doesn't define definitive steps toward AGI.

It's not so much that digital security isn't important -- it's that if you are not a "nobody", and you have something to hide, digital security is further down your list of your worries.

I think too many people think about "digital security" in isolation, without any human context or considerations of threat profile. Digital security without holistic human security is simply a math exercise.

They have less a moat here. Anyone can buy a level 3 charger and install it. while the economics of that are not clear, they are becoming clearer as EVs catch on. Many gas stations are looking at if chargers make sense long term, and if it does they will also install chargers.
Why should they? Serious question. What’s their incentive/motivation?
But what’s the point? Why do individuals need level 5 cars?

Why not just make tons of public transit at that point using the level 5 tech instead and cut traffic?

As a Serb, I wouldn't really describe Serbia as being unaligned/centrist. The corrupt politicians (I wouldn't dare call them people) in the gov't itself eat from the laps of Russia because the West = Evil for some nebulous reason that nobody quite understands anymore (slightly exaggerating, it's mostly to do with Kosovo and NATO involvement in the Yugo wars in the 90s but most of the youth don't give a shit about that anymore), while the youth, at least in the bigger cities, tend to support the EU and want Serbia to join them one day if we're to have any hope of advancement.

At the same time they're also selling the country to the highest bidder, which for now are various Arab states like the UAE and the Saudis (lookup the Belgrade waterfront as an example), though there's also lots of Chinese money flowing into the pockets of the politicians as well.

It's a horrifically corrupt country with legitimate war criminals and their leashed dogs (like current PM Vucic) still holding the reigns, trying to scam and bruteforce their way to as much money as they can muster before the inevitable happens. Meanwhile it experiences insane levels of brain drain as anyone sensible and with the means to (my parents in the 80s and myself and pretty much everyone else in my family now included) gets the fuck out and never looks back twice.

Mind you, myself and most Serb diaspora I know don't want anything to do with the place. I was born and grew up in Indonesia and have visited Serbia a handful of times at most, so it's not a country I'd call home in any sense of the word. Even then, it still depresses me how hopeless the situation seems for anyone living there, as relayed to me by the few friends and family that are still stuck there with no way out.

"Enron's fraud left nothing behind but a string of suspicious deaths."

Man this guy really knows nothing about energy...

Enron happened at the start of the shale and natural gas revolution that reshaped American energy and global politics. Enron's energy traders alone (including John Arnold) helped structure global markets for natural gas. Their physical pipeline assets are owned by Berkshire Hathaway. The fraud of Enron was on top of a real set of businesses, with massive physical assets!
What the US has is split phase power, when one phase is 240V and that is split to make two 120V legs. NACS supports single phase power, either 120V (Level 1) or 240V (Level 2).

There is no such thing as two-phase power, there is single-phase or three-phase. Since three-phase is better than two-phase.

A lot of shipped code is effectively unmaintained even on pages which are otherwise being modified, in many cases by relatively non-technical people (a small business owner contracts a webdev to build a page and show them how to update the content, for example).

And in a lot of cases it's not obvious that your code is going to be incompatible. For example the most recent case there was code which was like `function foo(x) { if (x.group) x = x.group; /.../}` where that function was being called with `foo({ group: [...] })` or `foo([...])`. That code breaks if `Array.prototype.group` is added. No one is going to figure that out themselves unless they test on a version of a browser which ships `Array.prototype.group`, and empirically no one does that.

Yes, we could find a way to break fewer pages than flash EOL broke. But even just a handful of pages people actually use is too much. No browser wants to ship an update which will break (to pick a relevant example) the website of the government of Brazil, even if they somehow "ought to have" updated their code before that update. Developers are empirically not going to do that update and browsers are not going to punish the users of the pages of those developers by breaking them.
Thank you. Feels good to know others think or feel alike.

"Not everybody thinks windows (aka, large holes in the wall, with just a thin piece of glass or if you're lucky two, between you and the hostile outside environment) are a must have."

No, but probably the vast majority thinks so. And actual daylight has lots of health benefits. But sure, the view from my window was always very important to me personally and I simply could not live in a basement with a view to parking cars. But being able to see the sky or not, makes a BIG difference. And if it does not for you ... then maybe you forgot what you are missing. And you actually do sound a bit paranoid:

"windows (aka, large holes in the wall, with just a thin piece of glass or if you're lucky two, between you and the hostile outside environment)"

If you are not living close to the streets, which is something I also would not like - what exactly are you afraid of? That a spidermen comes into your home?

The biggest intrusion through windows that I had, was a falcon once ... and that was rather interesting (and only happened, because I left the window wide open while I was gone).
Multiple minor UI glitches, search and note organization is a mess, the app is not local-first, it lacks offline mode which would be guaranteed to work on a plane, the editor is not bad but might be better, no encrypted backups, extremely limited set of syntax highlighters. And many, many other issues.

Across everything I've tried, Standard Notes seems to have the best set of tradeoffs, but they refuse to implement features (like add syntax highliters for modern lagnuages, if I remember correctly, they said that they would only consider it if I prove that thousands of people need it).

Anytype provides good privacy guarantees but they have crappy UX and, ergh, their app needs 5 seconds to start on a modern mac.

The whole notetaking apps market is a shitshow and a total mess. Don't waste your time and money on these half-backed subscription-based electron apps.

My IQ is orders of magnitude lower than the authors of the paper, but I did my best to work through it anyway. I studied CE and have the basic control theory background and undergrad level discrete time systems intuition. It would take much additional studying to understand state space models enough to really parse this paper. But I tried anyway. Take my comment here with a big grain of salt.

The overall insight of Mamba is to solve a longstanding problem with state space models. They are good at compressing the input context, but the compression of input into a hidden state erases information needed to make use of the context effectively as Transformers do.

Their solution to this problem is to create what they call a selection mechanism. The mechanism is input-dependent, allowing the model to adjust its output at each step as the input changes. How they do this is by making a few of the state space variables input-dependent instead of input-invariant. They choose a few of the state space variables and attach linear layers and such to project the input onto the state space variable at each time step. The linear layers (etc) are obviously trained so that they know how to transform the input appropriately so that the model spits out useful output.

But making the state space variables input dependent creates a problem in terms of computation overhead. They fix the computation problem by designing a machine architecture-aware algorithm that makes the most of modern GPU memory architecture, avoiding moving things in and out of HBM as much as possible.

Tri Dao came up with Flash Attention, which is basically a way to use hardware more efficiently in a Transformer. So this is his jam 100%.

I know this doesn’t add much to understanding the paper, but hopefully it’s better than nothing.

A Review of the Top Tools for Generating LLM Structured Output
A QuestDB engineer here: These are cool benchmarks! The idea to try Robin Hood probing came to me after receiving some feedback on Reddit.

In our experience Dot can come up on the fly with cohort analysis charts if the underlying data is well structured. In most cases however, some level of explanation, example or data preparation is needed for robust and repeated cohort analysis. Also for good query performance it's usually best to precalculate some things.

While this sounds good, why are we so focused on charging stations? It seems to me, it would make much more sense to have a series of batteries that can quickly be removed, and have battery exchanges.

Then, if you need a charge, you pull over to a battery exchange, swap out batteries in a few seconds, and go on your way.

I have seen this in China with electric scooters, and it seems like it could scale well for cars too.
I always wondered why things like this weren't more prevalent, and the only answer I could come to was "jobs".

That is, given the networks of underground infrastructure that already exist, it seems like this would be totally plausible for pretty much any midsize+ city to build this out to replace all conventional mail delivery (that is, basically anything that can fit in a standard size mailbox). But that would result in tons of mailmen/women being made redundant.

Am I just misunderstanding the complexity of building out one of these systems? Long term it seems like it would be much cheaper than current last mile delivery. I also realize that there are tons of processes that are kept inefficient due to "jobs inertia", so I don't think this is something new. Whenever I have to wait in line at the neighborhood pharmacy to pick up a prescription, I always think "How is pharmacist still a job?" Everything seems like it could be made much more efficient if pill cases were standardized and you could just pick things up at something resembling a vending machine. I'm not saying I never have questions for a pharmacist or want them to review something, but like 50% at least of the stuff they do should be automatable.

TfL/Boldyn/telco's roll-out of mobile coverage in London across LUL and the Lizzy line has been frustratingly slow, and dates have slipped repeatedly.

There's a forum thread chronicling the project and the successive press releases as goals have been watered down: https://www.railforums.co.uk/threads/lu-elizabeth-line-4g-up...

Proper (incl tunnels) coverage was promised "soon" after the Elizabeth Line opened. Indeed, the trains all advertised a completely pointless TfL WiFi SSID since day 1, which still doesn't work en-route because there's of course no mobile network.

This news is a good step in the right direction, but will still only work on platforms and in ticket halls.
