Bicycles (and related transportation such as electric scooters) are a really good mode of transportation between 0.5 km and 5 km; a lot of cities could benifit being more bicycle-friendly.

Copenhagen is not car-unfriendly given its size and history. Parking in the inner part of the city is expensive and getting around in car is slow because the city is not built for it (circa ++100 years ago). The newer parts of Copenhagen accommodates cars as any other modern city.

Another thing worth noting is that Copenhagen got is its metro quite recently (some 15 years ago) and it is not fully expanded. So the public transport alternative was busses and some trains.
But cops could also observe criminals, so that probably evens out.

In dense urban areas, 4G cell networks don't have sufficient capacity to enable large numbers of people to be using high-bandwidth services. E.g. if there is a road anomaly, such as construction, one of the solutions self-driving-car makers have invoked is a human remote driver jumping in. You can do that with a few cars on 4G, but not at scale with dozens of cars that might be simultaneously blocked by the same anomaly.

Ozu Yasujirō was famous for his use of static cameras and lack of action scenes. His films are probably the most low-motion mainstream films ever made, which means they do not engage your brain very much in interpreting the 24fps motion. And yet they are still highly regarded by critics, and in my opinion highly engaging in terms of characters and story. Would they have been improved by shooting at 12fps, to make your brain work as hard as it does with conventionally shot films?
What kind of workload are you thinking about, though? Why are you streaming these characters? What processing are you doing that doesn't already have conditional logic for each character?
The String (and CharSequence) API are already warped around the assumption of underlying UTF-16 storage. In particular `charAt()` refers to a UTF-16 code unit position, and in general all methods [1] that take any kind of index are using an index into an explicit or implicit UTF-16 string. All of these functions need to be fast: certainly at least O(1).

So for your narrow encoding you need one that maps 1:1 (in a fixed-length way) to UTF-16. That rules out multi-byte UTF-8.

You could of course just restrict it to UTF-8 chars that fit in a single byte – but that's just ASCII! You waste a bit per character.

So you might has we'll use a full 8-bit encoding, and Latin-1 is convenient as it covers many more characters likely to be encountered in text that can use single-byte UTF-8 in the first place. It is also convenient in that Latin-1 and Unicode codepoints identical so conversion to and from UTF-16 can be very efficient (in fact there are SIMD instructions which do it exactly).

In any case, even in the scenario you could somehow use UTF-8 efficiently, it is likely to be worse in this particular scenario:

- They both use 1 byte for code points 0-127
- Latin-1 uses 1 byte for 128-255, while UTF-8 uses 2
- Above 255, UTF-8 uses at least two but the Java hybrid string will be using UTF-16 now, for a common case of 2 bytes.

So the only place UTF-8 wins is for the unusual case of characters outside the BMP which are 3 bytes in UTF-8 but 4 bytes in UTF-16. Those aren't common at all, and in many scenarios where you'd have a lot of them UTF-16 would still win because it represents many characters in the BMP in 2 bytes that take 3 in UTF-8.

---

[1] One might think there is an exception illustrated by the few methods that mention "code point", like `codePointAt`. Yes, these deal in code points, but their indexes are still indexes into a UTF-16 string. So they are kind of a hybrid API. They let you count N UTF-16 code units (which will represent <= N code points) into a string, and then deal with the code point at that location. That leads to weird cases like asking for the code point starting at the second half of a surrogate pair, which gives you the low surrogate alone.

You have my support for bleeding advertisers (and paying taxes ;) ) but I do want to point out one thing which is sometimes overlooked:

> some I think were reported stolen as well

If true, that incentivises phone theft. The only reason people steal phones is because there's a market. Every purchase of a stolen good directly incentivises that thief to steal once more. It's a very direct link. If you've ever had anything stolen, please break the chain and consider verifying somehow, some way, that your next purchase wasn't originally lifted off someone else. It can suck, especially if you've been a victim yourself and it's just unfair.

Other than that thanks for doing your part in poisoning the advertising well :)
The past 50-60 years strengthened the positions of governments vs. their people. These days such a movement would find it a lot harder (or impossible) to go that far.
While true, the leak was of a list of E3 attendees. The fact that it was of E3 attendees is the key fact. I tried different ways to fit ESA in while maintaining specificity, but all variations came out too long.

ESA instead of E3 wouldn't necessarily tell E3 attendees their information was leaked since not everyone knows the ESA puts it on. Personally, I've been around games all my life and had no idea.

Headlines are always a compromise. I think the author found a good one.

Yes, the variable length nature of UTF-8 generally means more hard-to-predict branches. But sufficiently clever programmers can find ways around that, see Lemire's work on using SIMD to validate UTF-8 very quickly: https://lemire.me/blog/2018/05/16/validating-utf-8-strings-u...

As a former animator, let me tell you that cost-cutting tricks are insanely important parts of the process. Hell, it’s a part of any process - there is a balance to be found between making a thing “perfect” and making it in a sane amount of time. Very few projects have infinite deadlines and budgets.

24 is good enough to produce a caricature of reality, with slightly different rules that are much easier to bend. That’s pretty damn useful for storytellers.

How would you argue for it then? Let's take a similar "defense" in some unrelated scenario that we have some distance from.

Let's say someone demonstrated that they are a xenophobe, inevitably someone will call them "racist" because it carries more rhetorical weight and is effectively the same thing (using arbitrary unrelated quality about someone to justify discrimination).

Now their "defense" will be that "no no, I am a xenophobe not a racist". How do you effectively convey that this is a bullshit defense and the connotations of racist apply equally? Without going into nuance where you will lose most people... :(

It just seems super hard to even make a real estate investment as there is no algorithm to work out if your investment will even yeild postitive ROI.

Also, it seems that big investments depend heavily on political climate and some people are just closer and more aware of what's gonna happen next law/rule/policy wise and it makes us feel like we've no connections so can't really win in investment world.

There is simply no compatitive advantage.

Fun fact: because flags are a political nature, and Unicode did not want to limit the length of country codes, any number of Regional Indicator Symbol code points can be placed back to back and treated as an extended grapheme cluster.

60fps is still too low for very fast motion, of which sports is a notable example. And the focal point of most sports is a ball, which moves along predictable paths, so motion smoothing can do a good job of increasing the frame rate to the point where the sample-and-hold blur of 60fps isn't visible.
The Gripen first flew 31 years ago, even at the time was considered an outrageously expensive project given the market size (Wikipedia tells me only 247 were ever built!), and frankly there's significant disagreement as to whether it even represents an improvement over the F-16's everyone else was buying at the time.

It was a stretch, and they made it work. But I don't think you'd call this a success. The Viggen was closer to that, and it was a 1960's design.
At Chichen Itza, tour guides there will tell you that people there actually competed in pelota (ball) games for the honor of being sacrificed.

Music as well as Films are pieces of work who are only really existing in their projection, a playthrough or a concert. Everything that mangles with that projection without beeing a willful choice of those projecting it makes it harder for artists to speak to an audience in the way they intended.

There are perfectly fine reasons to change a projection, e.g. for the or visually impaired or because you just prefer it that way, but ultimately it should be a willful decision to deviate from the expected default..
I personally have done a startup in Java in 2004, and have written Java code for money as recently as last year. So I feel comfortable saying Java is generally a bad idea for startups.

Java was the core language for Android because it started in the early 2000s, when Java was the new hotness. But it is no longer the primary Android language; that's now officially Kotlin, because the majority of developers had already switched away from Java: https://techcrunch.com/2019/05/07/kotlin-is-now-googles-pref...
Maybe the metro explains why there are so many more cyclists in Copenhagen than Stockholm: the daily ridership of the Copenhagen metro is 200k while the one in Stockholm has 1200k.
Great post, agree on all this.

One thing though: I think many cities as you say are now overpriced. Even with all the qualities of expensive cities like London, you get very little for what you pay for. That means there's an (economic) information lag where many people don't realize this yet. I hope my site helps reduce that information lag.

I think cities attracting people will happen organically as it's mostly always has been. People go to cheaper/better places to save money, then those places develop, get expensive/crowded etc.

In terms of non-organic ways of attracting people, I know governments in Spain, Ireland, France, Georgia, South Korea, Thailand, Taiwan, Indonesia and a few more countries where ministries (eg of tourism) are actively aware of remote work, nomads and wanting to attract them.

The challenge is that the things remote workers are attracted by in a city are either fixed (weather) or slow to change (internet speeds, infrastructure, safety).

Places that have become hotspots for nomads like Chiang Mai and Bali mostly did because they already had a giant tourism industry and supply of (cheap) accomodation, were relatively safe and had usable internet. It "happened" to them, not the other way around.

I don't like the exception but there's not a good answer to this. There are some drinks that people want that only exist in canned/bottled form. You could get soda from fountains but energy drinks, lots of coffee drinks, premade teas, sports drinks, unpopular sodas, etc. wouldn't be worth the whole fountain and so would just be gone.

The goal of this change should be to make an easy positive step not make people worse off because they now can't get their favorite drink when they're already probably stressed at the airport. So I totally understand the exception. I think the next step would be requiring that 'popular' sodas be fountain only.
They're not ridiculous taxes, they more or less match the immediate cost to society of private car ownership: maintaining the road networks, health care for people involved in accidents or sick because of pollution, etc. If car owners paid the indirect expenses as well, environmental impact, the value of the land occupied by roads and parking, etc, the taxes would be much much higher. Even in Denmark car ownership is massively subsidised.
I wonder why NASA opted for an SLR when the modified versions would need to be operated through an external viewfinder. Same with the first Nikon Fs they sent up in later missions.

I think that's exactly it. Many in-house tools are designed not for the users but for the people with power and budgetary authority.

As an aside, I think that's why Agile and Lean methods have been mostly adopted in name only, leaving the substance untouched. The goal of both movements was to shift power to people doing the work, and managers see that as a reduction in importance.
This is useful, thanks for sharing.
There is unfortunately a large gulf between “agile” and “Agile” development these days. The former refers to development generally in line with the agile manifesto, with processes tailored to the needs of the team and the project. The latter is a buzzword used by consultants to convince management to put their favored bureaucratic method in place, usually some variant on the scrum system.

Good point, but you are lumping all gun owners into one mindset.

I could definitely see that happening, but it would not be all gun owners, just a percentage. And of the many gun owners I know, the percentage that would support any government and impose anything on others would be really low.

Phew, then at least displaying 24 fps movies without interpolation should be possible because 120 is an integer multiple of 24.

You're right! My bad - the first characters are encoded the same across ASCII, UTF-8, and Latin-1, but the second half of Latin-1 differs from UTF-8. So even just having to support those first 256 code points, we jump into multi-byte UTF-8 territory, meaning complexity over Latin-1.

First, I disagree with the author's post that all software developed at Google is revolutionary low-level technical infrastructure. But that's not the only type of software development that benefits from avoiding the productivity tax that agile imposes.

There are teams at Google that look to use agile methods. E.g. I see standups, there are internal tools that track sprints, etc. I think these are mostly front end teams.

I've never worked on front end but was on a team that used scrum at a previous job. I hated it. It seems like a huge impedance mismatch for my kind of work.

I'm guessing some consultants sold management on the miraculous benefits of scrum at my previous job, they like the snakeoil they were sold and forced scrum on everyone. The amount of overhead process it brings is an enormous tax on productivity.

Some people call this "corporate scrum" to try to distinguish it from real scrum. But this feels like a No True Scotsman fallacy. Why is it so damn hard to do "real scrum" and actually get the productivity benefits it promises? I've never met any SWE in real life who has tried scrum and liked it.

At Google, the development process is not just "develop 10000 lines of code on their own" like some posts here have imagined. There is typically a design phase that gets wide buy in, and then code reviews, and extensive testing every step of the way during development. This feels far more realistic as a process.

And it is NOT some "waterfall" process which only seems to exist as a strawman for agile consultants to knock down. There is no architect who designs the code and then hands it off to code monkeys to go implement exactly as written. That's ridiculous and now how software is written anywhere as far as I can tell.

If I were to answer the question in the title myself, it's that Google has allowed engineers to build a process that works for them, and they almost never pick scrum or other agile methods.

Showscan and other high frame rate formats are indeed great for simulating reality. That’s why sports is mentioned in the article. If you’re building a flight simulator, sure go and use 120fps.

But cinema at anything higher than 24, looses its sense of Impressionism. 24 is not the way we see the world in our normal life, and that’s just the point. Look at an impressionistic painting. It just isn’t what we see in our normal life, and again that’s just the point. It’s flaws are the point. It’s what makes Impressionism its own medium vs realism. Movies in 24 are simply Impressionism. Yes it was an accident 100 years ago but it worked.

'short term planning' appears to be your construct, not found in TFA.

Short term implies reactive / tactical -- not the planned / strategic level that TFA is talking about.

It may well be that Agile 'precludes long proof-of-concept projects', given its essence is 'better ways of developing software', which clearly hides a wealth of complexity behind the heading of user-facing software.
