Two things which radically shake up EV worldwide, are a pricepoint closer to reality for working people, if need be shored up short-term by government assistance, and realistic information about milage.

Two things which impede take up are governments obsessed with the income streams from road and petrol taxes, and individuals on the edge of the curve for distance or load, who decry the vehicle can serve their needs. It obviously can't but they just haven't run the numbers. We have 10,000 people in cities, for every farmer. We have 1000 people in cities not doing trades with 400km drives, for every one which does.

It's entirely true a small family car which can't do 500km will not suit a farmer or tradesperson who has a 400km daily commute with a tonne of stuff in the back. Statistically, the overwhelming use of cars in western society is for short hops, under 150km. Some people (a lot) are <40km a day.

It is also true that as volume ramps up, supply of recharge facilities is going to be a pain point. And, that LONGTERM the supply of lithium and other inputs is concerning against the rate of mining and industrial development. These are entirely solvable problems. There is no impending Erlich/simons "limits to growth" in lithium.

If I have to see another input saying "we don't have enough lithium for the coming 4.5million cars" as if they are all due to arrive next tuesday, 4pm, or "batteries are useless after 10 years" which ignores massive amounts of clear sensible potential re-use and re-cycling in the battery, I think I'll scream. I do acknowledge mining is dirty. All mining. If you don't like lithium mining, you're ignoring the fugitive methane problems in Oil and Gas, and mining in generals effects on the landscape to get aluminium and steel and magnesium and plastics and glass and tires.

The biggest missed opportunity here is definitely pricing. If I was in car sales I too would have priced to the peak. But what we need, is price to the floor. We need the processes which drive to a $20,000 car, not a $120,000 car.
The author is right here, that a Bolt is a more significant EV than a tesla. And the coming VW ID4 sled will be too, if VW get pricing right. And the BYD. and MG. China is all over this space.

The second biggest missed opportunity is battery swap. It works, and it works at scale, and we know it works. It requires socialising batteries as shared commons you "rent" and it requires policing to get bad batteries out of circulation, but it solves the recharge time delay problem. It just didn't suit Musk, and didn't suit his ideation of Tesla in the market. Putting batteries into the subframe and the structure won't make battery swap any easier.

I tried to get the body corporate of my 5yo condo to talk seriously about charge stations. It was impossible to get them over the capital works cost. The developer who made this condo, put them into all their subsequent developments and to me, that tells a story. There has been no above-cpi increase in the cost of sales in these newer condos: it's simply a cost of doing development now. Sucks to be in an older building, with a body corporate scared of capital works.
How we treat our wounded and hurt is so incredibly fucked up. I won't candy coat it - if we put you to training and battle and you get hurt I fully expect you + family to get an upper-middle-class experience.
The issue is more that the lack of amendments proves that we are no longer a "United" States.
I would still love to learn vim if only for the nerd credentials. However I cannot imagine how I would reproduce the workflow to even come close to approaching my current productivity level with VS Code.

I'd love to sit down with a vim expert for a day and see how much of my workflow I could replicate.
I keep notes whenever I have a good gift idea for someone specific. Example: during our trip to Chile, me and my girlfriend stayed at an Airbnb where they had a child's xylophone. My girlfriend loved to play it and even learned 3 songs before we left. I realized it would make a good gift so I wrote it down on a note titled "Good Gift Ideas" in Google Keep. A couple months later on her birthday I bought her a similar xylophone.
Video games prepared me for building a startup.

Each game was a set of unfamiliar rules that I'd have to learn quickly and optimize decently well against. Once I got good enough to reach the upper echelons of a game, I'd get bored and do the same with a new one. Repeat with dozens of different games, and it's very similar to the feeling of all the new unfamiliar things one has to learn in building a company.

Plus, the game that generates the closest feeling to building a startup as a whole has been Civilization :-)

And, it turns out ideas from games can be useful in products too: https://parsnip.substack.com/p/tech-trees

If a feature is not enabled in a browser by default, it doesn't count as "Yes, supported." Sites can't be designed expecting users will all go into their browser's experimental features list and turn things on.on

I didn't claim this was a supported feature, just that it wasn't accurate to suggest that WebKit has no support for some of these features that seem to be missing. They are being worked on and will be turned on by default pretty soon.

So the goal was to intentionally nerf Compare() to discourage code the golang authors considered less clear. I'm not sure bad performance is really discouraging usage though, it just penalizes folks that use stdlib.

I wonder if they'd accept a PR to switch to runtime.cmpstring today?

> so what makes a variable different from a function? Nothing really. The great thing about Lisp is that almost everything defined under a define statement is treated the same.

this is one of the bigger differences between languages in the common lisp family and those in the scheme family. schemes have a single namespace that's shared across functions and data while common lisps have a separate function namespace from other values

(One of) the things that pisses me off about this is all through Tesla's marketing and website, the consistent undertone is that these are complete and working, but that much of EAP and FSD is "just awaiting regulatory approval", when that's far from the case.

Of course, it's very convenient for Tesla, too, if it never happens (and I think we are a decade or so at least from anything), they will just point blame away from themselves, ignoring that what they've offered would never reach the barrier for regulatory approval. And there will be the usual cries about the short sellers, and "big oil" pressure, rather than placing blame where it lies, Elon's cowboy-esque attitude to the whole thing.
Really wanted a 2nd set of Robot Inventor, and now it's both discontinued and sold out everywhere. Ugh.
Multics used segments and Lisp Machines had a single address space. UNIX breaks down quickly without multiple fake single address spaces for each program.

> Programs just have to be compiled relocatable.

Yes, and with unrestricted memory access, one program can crash the entire system.

> You know, like what happens with shared libraries: which are written in C, and get loaded at different addresses in the same space, yet access their own functions and variables just fine.

That is except when one piece manipulates global state in a way with which another piece can't cope, and at best the whole thing crashes. Dynamic linking in UNIX is so bad some believe it can't work, and instead use static linking exclusively.
Exactly, the article should have arrived at the conclusion that the problem in the US right now is that party politics predominates over the pursuit of the national interest. Instead it arrives at a prescription that could potentially greatly worsen party politics.
I leave my laptop in the cafe all the time. Depending on the location and the people around, I’ll ask someone nearby to keep an eye on my stuff.

Edit: this is in America. In Eastern Europe, where petty theft was widespread, I’d only do it in upscale locations (e.g in the de-facto ‘embassy’ district) or when I was friends with the staff and could trust them to keep an eye on my stuff.
As an alumni, not psyched to hear this. I’ve always loved walking around campuses and thought openness was a great aspect of the university culture.
I can't tell which parts are agreeing or disagreeing with the quoted statements. Is doing versioning explicitly in a database necessarily more complicated than with git histories?

Using a distributed datastore should make operations simpler and more transparent without having to think about the distributed nature, other than latency of operations. So if using a distributed datastore achieves distributed nature, is the tamper-evidence what's needed and missing or something else? For a cloud-based app, redundancy/fault-tolerance is the concern rather than being distributed unless you're running a globally distributed platform that can't be partitioned.

There are a number of actors who buy bugs like this - you largely don’t hear about them because once they became notorious it gets harder for them to do their jobs.

(Just kidding. Not sure about that pilot, but the book's author, Ron Knott, has written a number of Christian books. Wouldn't surprise me if that's related to why the book included that story.)
No less a jurist than Antonin Scalia (one of the most conservative and intellectually formidable Supreme Court justices, whatever your opinion of his positions) thought that the US Constitution was too hard to amend:

"Scalia said fewer than 2 percent of the population could prevent enactment of a constitutional amendment. “It ought to be hard, but not that hard"

The bizarre circus of Supreme Court nominees coyly pretending to be apolitical in a plainly partisan nomination process is another indicator that there's something wrong.

People keep saying this (the republic vs direct democracy part), and it literally doesn't make any sense, to the point that I have difficulty believing people aren't being deliberately obtuse.

Having people directly elect their representatives is still very much a republic and in no definition I've ever seen considered direct democracy. We're talking about people electing their representatives, not their laws.
I'm really excited for the performance boosts that are in store for Python. Having written production services in Python, Go, Java, C++, and Javascript, I can confidently say that I hate Python the least. The only thing keeping me from becoming a full-on evangelist is the comparatively poor performance. Any day now a hero will come along and excise that pesky GIL...
> we can make machines with vastly better error correction for their replication

Absolutely, I think we agree on that. It's fun to think about whether machines with some intentionally elevated drift rate may occasionally outperform locked-down ones, but I doubt it would be worth it since I don't see a random walk algorithm like evolution beating intentional design strategies implemented by extreme intellects. (Especially since they'd be able to simulate designs beforehand and could easily consider vast numbers of variations in advance...)
If you’re interested in this odd Australian time zone, Lord Howe Island (10km long, population 350, hundreds of kilometres east of the mainland) also has its own time zone for half the year.
It's a shame the Candu nuclear technology was abandoned [1]. As the name suggests, it's a Canadian technology. It uses heavy water as a moderator (and coolant) in the core of the reactor. Heavy water is very expensive, about 1 billion dollars per reactor, but it's a one-time investment. The benefit is that the reactor can (and does) use un-enriched Uranium. Nowadays, people think enrichment could be an obstacle in the nuclear renaissance, since the main commercial enrichment plants are in Russia.

The SMR mentioned here does not use this technology. A competing SMR with Candu technology was in the race, but for some reason it lost. Oh, well, at least they are funding another SMR.

Cool technique but it would be cooler if you could cut the Rpi out of it. Do they make IC clips that can connect to the USB port of a laptop? If so that would be easier and less error prone than mapping the IC clip wires to the GPIO pins of the RPi and having to go through the trouble of connecting a KVM to what is, effectively a $35 throw-away computer. (Or, I suppose the best case would be an IC clip that plugs into the USB-C port of your phone, and you can run the software in an app...)
Elaborate on this. How do political parties affect the equation here, and what would the more modern approach be? Any texts you can recommend regarding this?
It's a great thing because where you live matters. I have no idea what's going on in the wilds of Wyoming. Wyomingites do. If Californians were represented by population, these lands would be managed by people who do not live there. That is terrible.

Option 1 is a reasonable explanation based on the behavior that arguably works best for 99% of users .

Option 2 is a “data grab” with no evidence or theories about who is grabbing what data and for what purpose.
MIT has public spaces and a museum too that recently reopened in a new place. They hosted events at the Cambridge science festival a couple of weeks ago as well. The Cambridge symphony orchestra is using their performance hall again (after a Covid break) .

Though there were a few groups that would use their classroom space for meeting and I wonder if that is going to end. The quasi public dance events and the board game group in walker memorial might be student only (alumni and affiliates would also shut out)

The unsaid issue is of course bathroom access…

Also, MIT is one of the few private institutions in which the vast majority (85%) of undergraduates graduate debt free, which is particularly surprising given its pedigree.

Their graduate school costs are another thing entirely though.
If RDS could fail over in 1ms I would be extremely happy. In practice, a few minutes of downtime for things like DB upgrades is usually acceptable in the business I am in, however this is enough time to cause quite a lot of alerting noise.

If the window of unavailability was instead 1ms, there would be dramatically less noise, potentially none.
Fascinating, til. Thanks!

Was just at MIT. The new system is security theater, to do this properly you need multiple doors to not be shadowed.

Keeping MIT closed forever is analogous to how 100s of billions of shoes have been taken off due to one potential shoe bomber. It’s stupid.
I've been developing my own version string parser for a couple weeks now, in golang.

It's ridiculous to what lengths you have to go to understand which part of a string comes earlier or later.

Simple example: semantic versioning allows "1.2.3alpha" and also 1.2.3-beta", but which one comes first now...

- Is 1.2.3 > 1.2.3omega?

- Is 1.2.3 > 1.2.3beta?

- Is 1.2.3gamma > 1.2.3?

In the Linux world it gets even funnier cause they invented SONAME fields that reflect breaking API changes instead of forcing packages to comply with semantic versioning syntax. Oftentimes there is a package version of e.g. 0.4.7 that has an SONAME of 12.7 on the filesystem.

Add to that the ~prerelease suffix syntax in Debian based distros which are maintained downstream, and all the +buildid or .commithash or -revision123 suffixes and you've landed in string comparison hell.

When I started I would have never guessed that this is such a complex problem to solve in golang.

I don't know about Java or Go, but any time I've looked at a C compiler's output it's emitted pretty good assembly for "if (a>b) return 1; else if (a<b) return -1; else return 0;" kinds of input when optimization is on. As long as the type being compared is something the compiler can reason about (and/or has a peephole optimization for I guess).
It depends on whose interests are being served. In software, version 1.0 could be what made the project successful with the user-base while subsequent versions introduce features which help other entities such as advertisers & the interests of anonymous share-holders to extract profit & control from the user-base. Sometimes, popular features, such as an open api, are removed to consolidate the market as well.

I'll take a version 1.0 which is focused on reifying the natural God-given rights of man vs version 3.0 which reifies power of the State & Corporate "persons" over man.

This is sad; I agree with other commenters about meeting interesting people thanks to open campus access. Last night on campus I met a welder from up north. He’d come to play D&D with a group that meets on campus, and we spent a couple minutes talking about the game and his character.
So, by your standard, the Bill of Rights can’t be “broken” by a lawyer, that is, they can’t get a court to apply it in something other than the intended manner. But virtually every significant phrase in the Bill of Rights has been applied in multiple different ways by different courts over the years, so clearly lawyers have had no trouble breaking it.

MIT's openness is a huge wedge issue in the Harvard-MIT culture wars. That sounds like stupid elitist junk, but makes since historically. MIT wasn't always... "MIT". Not too long ago, it was just another college. Its open culture combined with proximity to austere academic/government/private institutions is one of the two reasons that it grew to be the behemoth is it now. The literal openness to the public has long been a huge source of "soft power" for MIT.

(The other reason for MIT's rise being WW2 and the military-industrial-academic complex ofc)

Even with this topic set aside, MIT has been turning into just another Harvard, which is a real shame. MIT alum used to be very proud of the fact that any and all were welcome to participate in many aspects of campus life.
Just curious if it accounted for other factors, like socio-economic status?

also of note:

Further, the researchers stress that this cross-sectional study does not allow for cause-and-effect analyses, and that it could be that children who are good at these types of cognitive tasks may choose to play video games.

Also surely the type of video game plays a huge role. I can't imagine hours spent killing bots in Unreal Tournament did me much good. But I did learn words like "critical" and "paralysis" from playing Pokemon Yellow.

One thing I do credit to video games - and I'm sure is similar with a large number of HN'ers - is my current career in software engineering. Installing cracks, mods, skins, etc. You learn about the file system, how to edit files, anti-virus software (to check the cracks you downloaded), and how to reinstall Windows XP when the crack turned out to be a virus.
