The problem is rural flight. We have insane housing pressure in the largest cities (Munich, Berlin, Hamburg, Frankfurt), but a loooot of vacant housing in the rural areas - over 10% of units [1], in extreme cases in Eastern Germany 15-18% [2]. Turns out young people flee in droves as soon as they can, when they don't even get ADSL at their home, where they don't have any chance at employment, or where neo-Nazis have been taking over.

I have been working on a portable camera array to put real video on these displays. The video demos are either projected depth maps or very expensive, stationary, indoor camera rigs. Despite trying to stay away from AI generation, making the array sparse, then synthesizing missing angles and dropped frames actually solved a lot of problems better than more hardware.

I'm old enough to have built systems with similar techniques. We don't do that much anymore since we don't need to, but it's not rocket science.

We had spell checkers before computers had enough memory to fit all words. They'd probabilistically find almost all incorrect words (but not suggest corrections). It worked fine.
What’s wrong with Lufthansa? It’s the only international business class I’ve ever flown. Had good experiences compared most domestic airlines in the US.
I'm not sure it's something the government wants to or can fix.

Many apartments that are being rented are those that house people otherwise, Paris being very well known for emptying out in July/August. For those that are being held back to rent, it can probably be hard to know what's the truth, "we didn't find a tenant" versus "we didn't want to find a tenant."

Also, I think there's also a benefit to the government, as they want to have this empty short-term housing stock available for tourists coming in. A lot of money is being invested in the games, it's important to get the tourism money to make it profitable.

DHS and the federal government in general require a surname and a given name. If one does not have one of those, your first or last name will effectively become FNU/LNU (first/last name unknown). For example Teller of Penn and Teller changed his name to "Teller", but passport says "FNU Teller"

One thing that may have an impact on the answers: you are hiring them, so I assume they are passing a technical interview. So they expect that you want to check their understanding of the technical stack.

I would not conclude that they over-engineer everything they do from such an answer, but rather just that they got tricked in this very artificial situation where you are in a dominant position and ask trick questions.

I was recently in a technical interview with an interviewer roughly my age and my experience, and I messed up. That's the game, I get it. But the interviewer got judgemental towards my (admittedly bad) answers. I am absolutely certain that were the roles inverted, I could choose a topic I know better than him and get him in a similarly bad position. But in this case, he was in the dominant position and he chose to make me feel bad.

My point, I guess, is this: when you are the interviewer, be extra careful not to abuse your dominant position, because it is probably counter-productive for your company (and it is just not nice for the human being in front of you).
.parquet files are completely underrated, many people still do not know about the format!

.parquet preserves data types (unlike CSV)

They are 10x smaller than CSV. So 600GB instead of 6TB.

They are 50x faster to read than CSV

They are an "open standard" from Apache Foundation

Of course, you can't peek inside them as easily as you can a CSV. But, the tradeoffs are worth it!

Please promote the use of .parquet files! Make .parquet files available for download everywhere .csv is available!
In no way I intended to be dismissive of you work or the RISC-V architecture. I apologize if my words could be interpreted in that way. I actually think that RISCV is a really cool architecture, mostly because it is open. I would love to see it getting more traction in the hardware world. I also think that your work on libriscv is impressive!

My criticism was at the idea of using a RISC-V emulator as a scripting platform. And I'm not saying that it doesn't work, only that I personally think that Web assembly seems a better option for that particular use case.
Ask HN: Do you have examples of (very) convoluted APIs?
I once contemplated an API where I would convert audio into a video, upload it to YouTube, let their Content ID detection run and then get their detected artist(s) as output, probably hours or days later. A very convoluted Shazam :-)

Do you have other examples of real APIs where lots of weird, slow, unexpected complex stuff is/was happening in the background, in order to provide the API response?
With the exception of regexes- which any programmer or data analyst ought to develop some familiarity with anyway- you can describe the entirety of AWK on a few sheets of paper. It's a versatile, performant, and enduring data-handling tool that is already installed on all your servers. You would be hard-pressed to find a better investment in technical training.

I don't exactly have the creepage tables memorized but that immediately jumped out at me! It's just too optimistic. Especially since it seemed not to have been covered in soldermask (although that may also have blown off?). There are all sorts of possibilities for bits of loose metal (solder whiskers, cut TH lead fragments etc) to turn up there and ruin your day.

Mains PSUs often have slots in critical locations to deal with creepage. Can't creep across an empty space.
>changing your profile picture to a model in a dating app, you are going to get responses but what are you going to do with them if there is no real match?

I may be a cynic, and I haven't tried this myself, but I would hazard a guess that doing this could boost a typical straight male's number of matches from none to a dozen a day. With that quantity of chats started, you can then experiment with various responses like "I don't really look like a model, but I identify as one" until you find someone receptive, with the benefit of loss aversion/sunk cost of her having already started a conversation with you.

Instead of the filter being the "match" both sides can then decide based on actually conversing.
Show HN: Use Go's HTML/template to write React-like code
Hi all,

I'm currently working on my hobby project, and one of the fun constraints I put in was to build using as less dependencies as possible.

I chose Go as it has a really good standard library, and all went well for building backend. But for frontend, I was wondering whether I should break the constraint and go for React. I tried options like Web Components, but I really didn't like the ergonomics and I didn't want to use jQuery either.

Out of curiosity, I was exploring Go's html/template package to see if I can write UIs in a React-like manner. I found most of the online docs using the "slots" like approach which I found unintuitive.

But after trial and error, I found an approach that's very close to React and without using any 3rd party packages like templ.

I'd like to share this with the community, not sure if it's a common approach - https://www.sheshbabu.com/posts/react-like-composition-using...
Densification only works when designing an area from scratch (like China), when you spend many many billions on retrofits or when it was built with sufficient sprawl to accommodate expansions in infrastructure. You can't just go and tear down other peoples' houses here, it's not the Soviet Union.

I used the ECA stack once. The weight loss was successful, but I also permanently injured my body during that time, and I think it might have been caused by ECA (large amounts of caffeine allowed me to push beyond healthy limits). So, you know, be careful.
I get the hate, but I find this semi-interesting. I flew business recently and the airline had a '3d' walkthrough of their cabin (i.e. 360deg photos at multiple points), a bit like property market listings where you have to press a bunch of arrows to move around. It may seem daft, and you may not be able to imagine someone using this in its current iteration, but I reckon as VR-wear becomes less clunky, stuff like this will be really useful. There are many air (and airmile) hobbyists and frequent flyers who like this stuff. So, hm, I guess people should just be a bit more generous with their good-faith tech curiosity instead of pouring hate?

EDIT: to expand a bit on why I like these walkthroughs in general: if I'm gonna spend a significant amount of money it's really useful to see what I'm getting for it. Unlike real-estate, you can't see an airline cabin unless you've already purchased the ticket and are fully committed. It's really that simple. Also if it's a rare joy, it's nice to build up a bit of excitement with these walkthroughs. Maybe that's dumb.
Building exhibits includes paying for parts, transportation, and labour costs, while grounding actual planes in order to train employees would mean missing out on vital revenue.

So… they can build physical mockups for trade-shows around the world, but not for their training centres at HQ?
> Almost all big data storage solutions are NoSQL.

Most I've seen aren't. NoSQL means non-relational database. Most big data solutions I've seen will not use a database at all. An example is hadoop.

Once you have a database, SQL makes a lot of sense. There are big data SQL solutions, mostly in the form of columnar read-optimized databases.

On the above, a little bit of relational can make a huge performance difference, in the form of, for example, a big table with compact data with indexes into small data tables. That can be algorithmically a lot more performant than the same thing without relations.

> Can't tell whether the two weirdnesses are different or similar

Because you focus on how they are similar and not how they are different, to me it is extremely obvious they are very different. Students make mistakes and learn and then stop doing them soon after, when I taught students at college I saw that over and over. LLM however still does the same weird mistakes they did 4 years ago, they just hide it a bit better today, the core different in how they act compared to humans is still the same as in GPT-2 to me, because they are still completely unable to learn or understand their mistakes like almost every human can.

Without being able to understand your own mistakes you can never reach human intelligence, and I think that is a core limitation of current LLM architecture.

Edit: Note that many/most jobs doesn't require full human general intelligence. We used to have human calculators etc, same will happen in the future, but we will continue to use humans as long as we don't have generally intelligent computers that can understand their mistakes.

I doubt it. The common Big Data Solutions manage to have a very high TCO, where the least relevant share is spent on hardware and software. Most of its cost comes from reliability engineering and UI issues (because managing that "proper ACL" that doesn't fit your business is a hell of a problem that nobody will get right).

Calculus is also mathematically shallow in that sense: the subject where you start with axioms and gradually build up the machinery of calculus is (Real) Analysis, which is not part of the standard calculus curriculum and which the vast majority of people taking calculus will never study [1]. A typical Calculus class expects students to memorize and use things like trig function integrals which are presented without proof; not so different from memorizing and using statistical tests presented without proof, in my opinion.

In an intro statistics class I think conceptual depth is more important than mathematical depth. It's more important that students really understand the concept of probabilistic inference, both hypothesis tests and confidence intervals, than that they understand the mathematical derivation of the t distribution [2].

Unfortunately intro stats classes often fail on this count as well. One of the (many) straws that eventually broke my desire to teach was a committee decision--a committee composed entirely of people not teaching intro stats--to disallow students from bringing formula cheatsheets to exams, effectively forcing us to make the students memorize formulas rather than focusing on conceptual understanding.

[1] When I took Real Analysis there was a calculus class that met right before us in the same room, which often ran over so that the calculus students would be packing up as we entered the room. One day as we're sitting down one of them asks us what class we're there for, and then asks what Real Analysis is all about, since he's never heard of it. One of my classmates responded with the absolutely perfect "Well, our homework last night was integrating x^2 from 0 to 1."

[2] I'd say the same goes for Calculus, for what it's worth; actually understanding what an integral means is more important than being able to set up the Reimann sum and take the limit.
Maybe it's the other way around: there wasn't enough environmental pressure to eliminate this trait.

From the paper:

“ instability is defined as the relative propensity of the subunit to undergo a physical disintegration of its structure, either spontaneously, or through the action of degradative agent such as an enzyme.”

Relative to what? other subunits.

The caption to figure 2:
“ If the B subunit is less stable than A subunit (indicated in gray font), this leads to a reduced population of AB replicators and free A subunits; this represents a more complex system because it yields a set with two distinct members.”

It’s not clear to me if this is the most general example they can think of, but later in the paper they relate SAI to a particular cellular automaton, Langton’s loop.

Overall 6/10, requires work, more erudite reviewers/promoters, or quantamagazine to determine if the field is indeed interesting.
Given that legroom, seat pitch and such is something that can easily be researched before purchasing a ticket. Unless someone is forcing you to fly a particular airline, is this something to complain about?

TLS is not bad, but CA TLS is for the vast majority of human persons on the internet. It makes things very fragile and only last a couple years max without constant mantainence. This is okay for commerce and institutions but for human websites it is devestating. Human persons just don't have the same use cases or threat models as a megacorp and cargo culting megacorp style solutions to everyone is bad.

"cutting exhibition costs by up to 80% and making training more scalable." and "When Lufthansa launched Allegris, a new seating experience for long haul flights, in approximately 150 of its aircrafts, it needed a scalable way to promote the experience with partners around the world. Lufthansa also needed to train flight attendants and call centre staff, so that they could better serve customers and upsell them to Lufthansa's First and Business Class offerings."

--> sounds like B2B sales/communication and internal training.
Admittedly, I'm not an expert. I believe it's due to the extra control flow points (assume all functions can throw, not just specially marked ones) and not having just a local value, which procludes analyzing the operations done on the error path.

I assume drive scale means 'serve ads', which somehow translate into more flights?
I can imagine something like "you haven't contacted xxx for a while, maybe you should see how they are doing." Or "why don't you invite xxx to yyy."
Agree. It’s a little embarrassing, but when booking flights, I do spend some time finding out which seat may be the best for my taste and seatguru.com isn’t always enough. So this could be helpful.

Also, we need experiments with new tech to find out if and how to use it. Why not have an airline give it a go?
In what country?

For example in the US today, scholarships are competitive (as any free money is), but the selection criteria has little to do with merit. Even top universities (MIT, Stanford, Harvard) specifically do not provide merit-based financial aid. There are some exceptions with private scholarships, but those are few. The majority of scholarships and grants are federal or federal+school, where the state puts a lot of specific requirements on the students, mostly based on need with some social mobility mixed in.

The result is that students go through a rigmarole that has very little to do with proving merit for the chosen field to the grant-givers who are themselves far removed from teaching or research in that field.

What I am talking about is a clear set of entrance exams given (or agreed to) by the university itself. No intermediaries, pure merit. This is very far from how the scholarships work in the US today.
