Normally, I worry about things be free, but beyond transit turning into mobile homeless shelters (see the "Hotel 22"), I'm not all that worried about regional transit being free. There isn't much marginal cost, it takes cars off roads, you can save by not having to do ticket sales and fare enforcement, and traveling is enough of a hassle, I don't see it inducing that much demand for transit for shorter distances.
Do people who write software ever use computers? Software sucks!

Knowing what good looks like and getting there are two different things. There's tradeoffs, constraints etc. Not knowing the objective function is rarely the issue.
> I read recently that fusion reactor will also generate decay heat from all the activated components and this is comparable to a fission reactor.

I'd like to know where you read that as the entire idea is to build a reactor out of things that don't activate or are very hard to activate. i.e. things that thermalize or reflect neutrons.

Fission reactors produce tons of neutrons too (they kind of have to to work more so than fusion even) and that doesn't leave the containment vessel anywhere near as radioactive as the nuclear waste itself.
Depends if they're worldwide or not. South America is a pro-windows outlier, and both Asia and Africa tend towards it as well.

Most tests I've seen, such as [0] don't support your statement. Zstd can compress almost as well as xz but decompresses much faster.

It can also compress more than xz with tweaks, though I don't know the compute/memory tradeoffs.

No proliferation risk at all in a tritium fountain full of 14 MeV neutrons? Are you sure you know what you're talking about?

These will all be guarded with pseudo military guns guards and gates just like fission, and monitored by the IAEA.

As for radiological safety, see point about tritium. And google tritium leak nuclear plant for good measure.

Youre right that there is less radioactivity in fusion plants, but maybe not enough less to really matter.
Apple seems to be reconsidering the exclusive targeting of the higher end of the market with the iPhone SE - I wonder if they may make a similar move with Macs at some point which would allow them to compete on price. Especially if Apple continues their emphasis on services/recurring revenue, I could see a future in which they sell a (relatively) inexpensive MacBook for the possibility of opening themselves up to a market of consumers who could pair that with the future equivalent of an iPhone SE and be happy Apple Music subscribers.
> We’ve been taught that UX is not only about function, but about delight, whimsy, wit, and beauty.

Similarly, China is notoriously terrible at international football, despite an enormous population and it being a reasonably popular sport.
I still think there is a place for a streamable, concatenable archive format with no builtin compression, plus an index sidecar for it when you want to trade streamability for seeking (PDF does something like this within a single file, in case you don’t value your sanity). People have made a number of those on top of tar, but they are all limited in various ways by the creators’ requirements, and hardly ubiquitous; and, well, tar is nuts—both because of how difficult and dubiously compatible it is to store some aspects of filesystem metadata in it, and because of how impossible it is to not store others except by convention. Not to mention the useless block structure compared to e.g. cpio or even ar. (Seek indexes for gzip and zstd are also a solved problem in that annoying essentially-but-not-in-practice way, but at least the formats themselves are generally sane.)

Incidentally, the author of the head article also disapproves of the format (not compression) design of zstd[1] on the same corruption-resistance grounds (although they e.g. prohibit concatenability), even though to me the format[2] seems much less crufty than xz.

> with omicron, even NZ's strict border control couldn't keep it out.

New Zealander here.

NZ could have remained in isolation, but it didn't.

The government basically decided we needed to open borders and that we would get Covid - borders were opened enough that it was inevitable it would get through.

I can say that successfully eradicating covid in 2020 was awesome (but 20/20 hindsight that the costs were worth it because it worked).

Even then, we still made some very poor decisions, like every country did in its own ways. Taiwan made amazingly good decisions I thought (they started their SARS response in Dec 2019, tracking and isolation).

Disclaimer: just my opinion based on what I saw. I don't have any actual insider information on the government decisions.
I kept Win 7 up until the machine was choking. It's a shame they couldn't just update that.
Interesting, Twitter $5,040 bounty to the vulnerability reporter. I've heard it said that website vulnerabilities aren't valuable and thus don't merit large bounties. But if a single copy of the database can be sold for $30k (I'm not sure it actually will), then this is a case of a bounty for a website vuln being much too small.
Sabine I've found to be spreading nothing but FUD personally. I've only watched a few of her videos but she seems to enjoy inflating minor issues into major ones and then proclaiming everything can't work.
Image caption:

> Traditional dehumidifiers are too large and too energy intensive to install in vehicles, but AirJoule’s compact size and zero net energy penalty makes dehumidifying air before cooling it in a vehicle not only possible but creates huge energy savings.

Uh, what? Pretty sure most vehicles have AC, which functions the same as a traditional dehumidifier. The only difference is the cooled air AC would output is run back across the "exhaust" pipes to reheat it, instead of ejecting the heat outside.

(No comment on the energy saving aspect, just the first part caught my eye)
It isn't, none of what I said was an attack on her. She's not a particularly prominent conservative thought leader at this time, she's right of center and seems to satisfy the definition of an ideologue (https://dictionary.cambridge.org/dictionary/english/ideologu...), which isn't a pejorative term, anyway.

What she isn't, however, is an architect, designer, business analyst or some other flavor of academic specializing in transit, and I think this is reflected by the extremely shallow nature of the rant she makes, which completely lacks analysis, depth or even handed consideration about why an airport might be designed to sprawl.

I also wouldn't rush to assume that private airports wouldn't just optimize for extraction of money from the individuals they host. That is in my opinion naive.

> Wet-bulb temperature is the lowest temperature a portion of air can acquire by evaporative cooling only

Yeah, exactly. How did you come about this?
> Users expect much more than returning bunch of blue links with matched keywords in response to their queries. They want much of the time direct answers to their questions.

Well, yes (and Google does that remarkably well sometimes) ... but also no. I often just want good results, damn it.

I do suspect that this type of technology would be helpful in judging whether a combination of words might actually be relevant to the query rather than just containing some of the same words - so the underlying challenge might end up being the same.
If you care about the question more than from a purely curiosity standpoint, there is a difference tween “flesh” and “body” in (at least some) of Christianity. The “Lord of Spirits” (an orthodox podcast) has done an in-depth discussion on both the body of God and the bodies of humans, angels and demons. Just as an example, when Adam and Eve was expelled from the garden they were covered in “garments of flesh/skin” depending on the translation.

I do not want to start a discussion on Christianity, just to point to that there is a more subtle understanding in the church whether or not you believe in it.

It didn't work in Germany. You have the impression that it worked because people are in holidays [1]. The trains are mostly overcrowded, partially working and the work force is burned out[2].

TL;DR:

"The Transport Ministry is providing €2.5 billion over three months to compensate for the loss of revenue caused by the artificially low ticket price — and yet no money was made available for extra personnel, buses or trains." With that in mind, he does not see how the scheme can feasibly continue after August. At least not at €9 per ticket."

If you don't set it to filter for price drops there is a ton of noise with the signal, especially with classic texts.

Add to wishlist as you go. Then review later for purchasing. If there is anything looking amazing at first sight, buy it right then because the price drop sometimes disappears after you navigate away (!).

The grid usage is pretty weird. It’s essentially using grids to implement an 8px base unit, which can be achieved with less complexity by using css variables. Would make a bit more sense if it used flexible units.

So that 10C difference only feels like 2C difference, but comes with the complications of being all sticky, which might make you feel more miserable overall despite being technically cooler.

Also, I don't know enough about wet bulb, but would it be possible that if humidity is higher, that sweat evaporates more slowly, and accumulates rather than just evaporating? If sweat drips off your body rather than evaporating off, do you still get the cooling effect (is it the releasing of sweat, or the evaporating that cools you?). Walking through a park on a summer day and a lab environment are going to be a bit different.

Basically, my question is, does wet bulb temperature accurately represent the human body, or is this a spherical cow moment?
Interesting to see that you care about technical debt even outside a team.

Technical debt has killed one of my projects once and I should really work to eliminate or at least minimize it.

The Blender OBJ loader was incredibly inefficient. Blender used something like two orders of magnitude more RAM than necessary, so even a small model would take gigabytes. It was basically useless for any model of even modest complexity. Working around its limitations was dozens of hours of effort when I was importing and rendering my own procedurally-generated models.

I was seriously considering rewriting the Blender OBJ importer myself. Ultimately, I ended up writing an OBJ to Alembic converter, since Blender handled those more efficiently.
Pretty much this. They could have called it Super Cruise Control or something and I'm pretty sure nobody would have anything to say, because it is expected that cruise control be supervised, but, I think people wouldn't be quite as willing to pay a lot of money for a feature that didn't sound so remarkable.

Depends on the transit agency. LA metro fare collection rate is probably 50% based on what I see. As others say the door sensors are the more reliable measure than the tap machine. Some train stations don’t have turnstyles and the ones that do don’t have the emergency gates alarmed anymore because people triggered them so much to avoid having to hurdle the turnstyle.

The first known curved staff was found in the Judah Desert in Israel, in the Near East. Small and made of copper, this staff is similar to the one used by the Egyptian Pharaohs. It is dated to the middle of the 4th millennium BC when dated together with the objects found with it.
I used to think the same, my layouts are full of spacer elements now. As long as they are semantically invisible it doesn’t really matter, but the combination of flex vertical/horizontal stacks + default spacers makes creating stuff much faster (and closer to how mobile apps are made).

Though in this case I would likely have a multiplier attribute in a single spacer, not multiple elements.
Are you agreeing or disagreeing with ars' claim that XZ provides a better compression ratio than Zstd? My data shows that it's true in at least one common use case (distribution of open-source software source archives).

1. That totally depends on the country. The social safety net in the UK is not great for example, and the NHS is barely functional

Folks seem to be comparing xz to zstd, but if I am understanding correctly the true competitor to xz is the article author’s “lzip” format, which uses the same LZMA compression as xz but with a much better designed container format (at least according to the author).

As in illustration, I'll relay you an actual story that I read from one Russian blogger (who witnessed it himself and I trust him that he did):

The scene is a couchette car in an overnight train between two Russian cities (a very popular mode of transport in Russia). It's late at night, so most people are preparing to sleep or sleeping already, so it is pretty quiet. Except for the two slightly drunk guys in one end of the train, who are engaged in a lively conversation. After a while one woman next to them loses her patience and shouts "you two over there, would you shut up finally? People are trying to sleep here!". To which one of the guys answers, not missing a beat, with innocent indignation in his voice: "And why did you think it's us?!"

That's how this culture works.

I don’t love everything about the new LaGuardia but it’s the way airport designs are going. A lot of it is done to prevent overcrowding at gates and around the terminal. It takes you longer to get from your car to the plane because the airports (and the airlines) want it to take longer.

Sure, it took five minutes to get from the car to the plane at the old LaGuardia but you showed up two hours before your flight so now you’re just sitting in a leaky ceiling glorified closet.

And walking through a shopping mall after security is nothing new. Just fly through any non-US airport and the first thing after security is a meandering path thru duty free.

Anyway, I think there are certain travelers (myself included) that spend a ton of time on airplanes and we try to minimize our time in airports. That isn’t the general public though.
