lol you think professors spend time on their phd students? they have postdocs for that...

edit: a typical research lab functions exactly like any other organization in the world: hierarchically. a chief executive/leadership role/head (the prof), his/her direct reports (post docs), their direct reports (phd students), and their direct reports (undergrads). if a phd student is being directly advised by the prof that's simply because the prof currently has no postdocs not because they don't desire some.
> The tourism industry has a significant impact on Spain’s economy, generating over 70 billion euros in gross value added (GVA) in 2019. This represents a substantial contribution to the country’s GDP and employment, with over 2.5 million people employed in the tourism sector

“Oversupply” is in the eye of the beholder. There’s a market clearing price for everything.

The builders can hold out for a while, but the shoe has to drop eventually. Builders only make profit when building, and if your credit is extended on old projects you can’t start new ones, hence why construction has halted.

The problem is covid. Pretty much everyone in any developed economy believes the inflation+interest rate increases will be temporary. So they’re betting inflation will go back to what it was, interest rate policy will loosen again, and people’s budgets will increase again.

There is no high-frequency trading in the cryptocurrencies world. It's medium frequency trading at best.

These cryptocurrencies exchanges (really broker+exchange mixed as one) aren't serving the data feed anywhere near quickly enough nor executing orders quickly enough to approach HFT.

Firm doing HFT are co-locating near the exchange and using direct data feeds, at times using algorithms running on FPGA. Stuff like that.

That's HFT.

I see AirBnB as a cheap-ish alternative to hotels, although short-term landlords are doing their best trying to extract as much money from their clients as possible (famous "$300 cleaning fee").

Thus, I don't think the city will really suffer from shrinking of the cheap tourism segment. Barcelona is already overcrowded, so making this crowd less dense and more rich at the same time is a net positive scenario. Also, the city needs long-term housing for those who work and study there.

There are lots of beautiful hotels in Barcelona. I visited the city about 10 times and never stayed in the same hotel twice, the choice is wild.

Wall-clock or subjective time?

I think it would take a human about 2.6 million (waking) years to actually read Common Crawl[0]; though obviously faster if they simply absorb token streams as direct sensory input.

The strength of computers is that transistors are (literally) faster than synapses to the degree to which marathon runners are faster than continental drift; the weakness is they need to, too — current generation AI is only able to be this good due to this advantage allowing it to read far more than any human.

How much this difference matters depends on the use-case: if AI were as good at learning as we are, Tesla's FSD would be level 5 autonomy years ago already, even with just optical input.

"In a million-to-one chance the brake failed to hold and although pilot Thrower grabbed a wing strut to check the plane he was quickly forced to jump clear, just avoiding the tail"

Parking brakes in light training aircraft of that vintage, if they were even equipped with one, were typically a hole drilled through a metal plate, that was placed on the actuator rod for the brake master cylinder, so that the metal plate would jam on the actuator rod and hold the brakes down when you pulled on a piece of string that was tied to the metal plate. They worked similar to the tab of metal to hold open the damper of a crappy old aluminum-framed screen door.

Parking brake failure in aircraft of that era is not a million-to-one scenario, it is the default operating condition. Go down to your local general aviation airfield and peek in the window at the parking brake knob on every Cessna 150 you see, I guarantee that many of them will be placarded INOP, and many of the un-placarded ones are also actually be INOP if you tried to use them.

They don't state the volume directly, instead claiming it's roughly half that of the ISS. According to Wikipedia the ISS is 1,005 m^3 and an Olympic-size swimming pool holds 2500 m^3. That would place this module at about 500 m^3 or 20% of a swimming pool.

Edit: This random Reddit thread says bananas are 156.1 cm^2 and pack with 65% efficiency. That means the module would hold about 2 million bananas.

That just doesn't seem like a big problem, in fact. The webs gotten pretty good & the standard is pretty high. Yes people have some real pains but also my word, software is a world of contrived griefs, nonsense beefs. People love grandstanding against things.
Thanks for sharing this experience - implementing a VM with GC is a core example of where a systems programming should shine.

The result shows that a direct solution (in less time than the C solution might have taken?) was not achieved, which can be attributed to inexperience. Then he got the safe version running, but with a big performance penalty. In a third stage, the code got more and more "unsafe" and performance rose close to the C implementation - without ever reaching it.

Some results from this - very well described - experiment is:

- Rust is a good language, but in development: the Rust developers still have a lot of work to do.

- IMHO, the safe version here is at the sweet spot; stop optimizing there with all the unsafe tricks (playing with the hash map is still fair game) and leave the rest to the compiler writers. Once they have put the amount of effort in that has gone into compiling Java, the graphs will look different. Safety is priceless, and who knows what buffer weaknesses clox has that can be exploited.

The post's writing is very clear, and I'm particularly grateful for the explanation of the problem the borrow checker has with GC in the main loop, and I can see how a lot of re-factoring solves one type issue in one corner only for it to crop up in another - thanks!
I also found it strange. The parent comment has some amount of hyperbole, but it does not detract from the point they are conveying.

Not in Finland. Each housing complex is a separate company, and when you buy an apartment you actually buy a share in the company. Until sold to the buyers, the housing company is usually owned by the construction company. Banks of course provide funding, but the construction company is the one left holding the bag if the apartments don't sell.
> Mathematics is a tool that can be used to describe the real world,

And that's what the article says the Greeks believed they could do using whole numbers and fractions. In the case of a real world square with sides of length 1 it seems that you can get away with describing the length of its diagonal in those terms which made it seem odd that it was what caused them to abandon their belief/aspiration. Maybe the author just described their dilemma poorly/strangely.

I'm not at all suggesting that math has to be limited to the real world or that irrational numbers don't have their place. We're certainly better off with them.

True, but that's semantics at best--as the other post said, if something is better but humans can't afford it, then it's better than humanity has to offer.

AirBnBs have also started increasing rates based on extra people.

Maybe it's just me, but when I'm on vacation the last thing I want to spend my time doing is dishes. I'd also rather explore where I'm visiting than sitting in some random person's house.

Give me a hotel room with turn down service over an AirBnB every time.
With a regular taxi I just call from a phone in a hotel lobby and ask to be picked up a block or so from my location. No reason there can't be a dispatch service you can call for self-driving taxis too.

You basically listed pretty trivial things, that like I said, let the construction industry operate on lowest bidder model in general.

As an example, I see bidding stats in my PM tool. On average my customers have a win rate of about 15%. One of the bigger companies doing $1.5 million a month of work has a 10% win rate. They are very good at what they do.. you can't half as your way into 15+ million of work a year, year after year. But they still win only about 10%. Because even though they are very qualified and liked, jobs go to the most competitive bid.
If you have a family of 5 or more, hotel rooms suck - either someone sleeps on the floor or you have to find a "suite" that accommodates that. Or multiple rooms.

The major travel sites all push you to multiple rooms - but lots of hotels now don't have "adjoining room" access (compared to say 30 years ago), and in one case, our 2 rooms were on different floors because of check-in time.

The travel sites are picking up on this and competing with airbnb as well. Typically my experience with those rented homes is a) cheaper than airbnb and b) better service. However, I'm sure they are the same type of superhost company that would be banned in Barcelona.
how is this functionally any different from a hotel? Do you complain that new hotel builds take housing away from locals, because presumably that hotel could have been residential housing instead?

> that makes electrons negative, and apparently nobody knows why

When there is a symmetry, there are choices, all the time in math, and sometime in physics too.

Also I don't like calling electrons negative, they are not. Maybe you can say that their charge is -1, when you model charge with the additive structure of real numbers / integers, and you choose the protons charge to correspond to 1. Modeling charge with the additive structure of real numbers / integers is very reasonable. (You could use red and blue numbers, but that's not a widely used structure.)

So you shouldn't say "electron is negative". That's weird, confusing, misleading, and trolling.
I have never run into this alleged issue. In fact, we have several times booked AirBnB homes in the town of my youth and hosted Thanksgiving Dinner for my elderly mom and siblings who are themselves visiting and staying in AirBnB's. Yes, we asked the hosts before booking if we could cook and host a Thanksgiving Dinner and received their OK.

I truly love AirBnB and have stayed in them in most all my business and pleasure travels to Europe, Canada, Israel and across the USA.

In New Zealand, Tourism gross operating surplus (profit) looks to be about 20% from graph in https://www.stats.govt.nz/information-releases/tourism-satel...

As a share of the total number of people employed in New Zealand, direct tourism employment was 6.7 percent.

I think the main problem with tourism is that it is a luxury service and tourism income shrinks when the world economy stinks. The other issue is that many tourists are rude and unthankful, so it can be unpleasant working in a service industry, being a servant to well-off tourists.

New Zealand needs export income. Some of our product exports are worse for New Zealand than tourism (some farming particularly has negative effects and can have poor profits).

I wonder if part of the reason why Barcelona has population growth is because it has tourism income and jobs? Remove tourism and what happens next?

And it sucks in New Zealand that some of the most beautiful places are crowded and almost owned by tourists. Literally owned by tourists when we let foreigners buy property here and our current government wants to allow that again.

I've been using ACCA[0] to set limits on battery charging on Android devices for years. Note that it requires root.

ACCA can limit charge percentage, allowing the device to operate plugged in without charging beyond a certain point. It can also pause charging when the temperature exceeds a threshold, limit the charge rate, and several other tweaks to charging behavior. By default, I use a charge limit of 60% and a charge rate of 500 mA, increasing those when needed.

That's the wrong metric.

> Instead, I was clever with virtual memory, and when a page of memory was needed that wasn't loaded by the recipient Pi, it would request and lazy-load just that page from the provider Pi, and with some careful bookkeeping mark that the page was owned by the recipient Pi.

I wonder if that "trick" can be extended to a full implementation of distributed shared memory, i.e. multiple nodes running separate tasks in a single address space and implementing cache coherence over the network. Probably needs quite a bit of extra compiler/runtime support so it wouldn't really apply to standard binaries, but it might still be useful nonetheless.
The entire impact of AirBnB + all housing built in the last decade does not offset the last half decade of population growth.

Your retort here simply isn't logical.

10k doesn't fully offset 100k but it's a significant chunk of it, and when supply gets so compressed as to become inelastic, a 10k amelioration (that is also prevented from creeping up to 15k or 20k within a few years) can be quite significant. Plus certain districts are obviously impacted disproportionately compared to others by not just the reduction in housing available but the sheer foot traffic and other blight that comes along with a lopsided rise in tourist accommodations.

The graphics are mostly for atmosphere, the main focus is paragraphs of prose that describe the story and what happens to the main characters. Instead of a parser, you tap to choose one of several choices at each decision point, and you can also decide which routes to take on the main map. Aside from that, you can buy and sell items to make money.

Your choices depend on where you are, of course, but can also be affected by your money, items in your inventory, and past decisions. So, for example, if you help an inventor in Prague, he may give you a device that you can use later in Delhi.
