> A big one is having four jet engines rather than two. If you had two equivalent aircraft but one a twin jet the other a quad, the twin would have higher efficiency.

One can make a good case for turbine engines having better efficiency the larger they are (less losses due to boundary layer friction etc.), so yes, if you have two otherwise equivalent aircraft I'd assume fewer bigger engines would be better. But here we don't have equivalent aircraft, as the A380 is bigger than, well, pretty much any other passenger airliner out there.

The A380 engines produce around 350 kN, which is slightly bigger than, say, the B787 engines. Admittedly the A350 engines are a bit bigger than that, but not by a huge amount. But the data seems to suggest both the 787 and 350 are much more fuel efficient than the A380?

So to make an equivalent comparison, one would take an engine, make a twin engine plane and a quad engine plane with that exact same engine. Naively one could expect the quad version to take twice the number of passengers or cargo, and have roughly the same fuel economy/seat. If not, why not? Which scaling laws are non-linear here?

> The engines on the A380 aren't actually that modern with the two options being 15-20 year old designs. One of the reasons it was discontinued is that no engine manufacturer was willing to make new engines for it, so they weren't able to produce a modern fuel efficient variant.

> And it also makes limited use of composites in its design, so it's heavier than it would be if designed today.

This explanation I can certainly buy. Also that the biggest turbofans are nowadays so large that a twin engine plane is already so big there's a very small market for quads.
I've never seen a more text book example of changing the subject when you don't have a real answer.

sk0g and hobofan point out a key benefit of animal testing, explain why there is no alternative at present, and rather than addressing that or acknowleding the point, you respond with non-sequiturs.

Try to learn to separate what you want to be true "animal testing is pointless" vs what is actually true "animal testing has benefits that cannot be sensibly found any other way". Then we can productively move towards eliminating animal testing. But if you won't even listen to others points, how do you hope to convince them of anything?
Not easily. One of the ways the media maintains this illusion is by carefully avoiding comparing coronavirus testing per-capita once the US figures became too good. For example, if you Google for this you'll only find articles from mid-May like this one: https://edition.cnn.com/2020/05/12/health/us-coronavirus-tes... and even those carefully only compare to the countries which had more tests per capita in order to push the narrative the US is far behind everyone else.

Looking at the chart at https://www.worldometers.info/coronavirus/, the US is 27th, with most of the countries above it being much smaller ones which are not an apples-to-apples comparison because there's more of them to cherry-pick and the wealthiest few can massively increase their per-capita numbers just by ponying up money and buying a disproportionately large share of global supply of consumables. The only large countries above the US are Russia (extremely fishy), the UK (whose press has been pushing about as hard on the narrative that our testing is behind the rest of the world as the US media has), and Spain. About a quarter of the countries above the US on the list don't even have 100k people, and only the ones I listed have much above 10 million. (New York State - population 19 million - would also easily beat the UK, Russia and Spain if it were a country.) It's also well ahead of the well-publicised testing success stories like South Korea and Germany.

Current testing rate in tests per day per capita is even more impressive: https://ourworldindata.org/coronavirus-testing

Incidentally, the US was one of the countries the UK press used to point at in order to convince us that our coronavirus testing was falling masssively behind the rest of the world and our government was failing us.
"It's shameful that we - as cartographers of the world - don't take enough interest to even know where they are. People are living and dying without appearing on any database."

I know. Context. Context. There's nothing wrong with the above, with last sentence in context.

But that last sentence makes me cringe, these days. The thought! The very thought that a human being may be anonymous, not counted, not known, not measured, watched, their every whim calculated and predicatively known, their essence stored for the ages.

A human! Look, over there! A human, and.. and... it's not in our database! YOUR NAME, NOW! YOUR ID, NOW! Who are you? What is your precise address? Who were your parents? Where do you bank, work, live? Write all your friends down on this piece of paper, everything you ever read or do, NOW!

In other contexts, in other paragraphs, that same sentence would be uttered by Gollum archetypes at Facebook, Google, the CIA/NSA/etc, well.. essentially, everywhere. The horror for them. Gollum, writhing at the thought, horror on his face:

"People are living and dying without appearing on any database."

How can this be?! HOW! Not tracked?!

All those that wish to profit, or mistakenly believe knowing when we take a dump, will "make them safe". Watch. Watch, spy, sneak, slither, control. Get the precious, hold it close, data is the new gold, the new devil, the new evil.

And they covet it.

All those little gollums, writhing their hands, wanting their precious, their precious data.

I have both devices but in this case it would be Chromecast Audio. I currently get by with casting my screen but native Chromecast support in Bandcamp would be much better - music would go directly from bandcamp.com to Chromecast Audio as opposed to bandcamp.com to my phone to Chromecast. Would save a lot of phone battery and the extra decode + reencode on phone that happens in casting the screen.
you are exactly proving my point. they sell a lot of phones. which means a huge chunk of their revenue is 1 product. app store is not a separate product. phone goes away, store goes away. itunes? I'm sorry, but it's an archaic piece of software that people install because it's the only way to get music onto apple playback devices. you know - the iphones. phone goes away, itunes goes away. there are a million other places to get all the same music.

the apple watch? the one that only iphone users have, because they have an iphone?

headphones? who buys apple headphones for their android phone again?

ipad? the thing that runs the os and the store from the iphone, which no one who isn't interested in phones would buy? people who don't like iphones won't buy an ipad. it is literally the same target market. whoever makes the new 'cool phone to have' is going to also make a new pad. phones and pads are tied.

and the accessories for all that - again, dependent on the phone 100%.

lots of people want to buy it (if by lots you mean a tiny fraction of the people). margin is high - it's not tricking people, it's selling the product as 'premium.' that tiny percentage of people agree. it's not actually premium for everyone else, since you don't own the device, and features are limited. when's the last time you chromecast hn to your big tv screen from your iphone again? how about plugging into a friend's computer and grabbing a music folder? he doesn't have itunes, and it's not a mac. how about storing your presentation meetings and some vm images for a product demo you want to do for work - or do you need a usb flash stick for that.

it's not 'really good stuff.' it's 'fad' - who in their right mind would wrap a phone in glass - those things fall a lot. would you buy a car made of glass?

everything you gave as an example is a fad that goes away in a minute when it's not cool anymore. it's no mark of a successful company. it's like calling a guy with a #1 hit a success. do you remember 'who let the dogs out?' so does everyone else. now, the iphone is no dog. it's pretty and shiny. a better example is rico suave. he makes shampoo now i hear.
I used to essentially be a professional Fortran programmer. It's been 7-8 years since I've done that, so this was a nice trip down memory lane. Anyway.

> Python3 (numpy 1.18.4) 1.3s FORTRAN (gfortran 9.3.0) 6.0s Rust (1.43.1, debug) >60s Rust (1.43.1, release) 4.0s

I suspect that you could get the Fortran and numpy results to converge by turning on the compiler option to use the local BLAS library for MATMUL, which will normally use an OpenMP-threaded solution.

Upfront note: these days "Fortran" is preferred to "FORTRAN."

> Fortran could do with proper namespaces, and properly dropping some of its older conventions, though. Reading it feels like archaeology.

The newer Fortran standards support pretty decent namespaces (USE module x, ONLY : y_ and a limited OO with classes and class methods. The problem, at least when I was doing Fortran work everyday, was that the compilers did not fully support the newer Fortran standards. We found the Intel compiler to be the best of the bunch, but we also found a non-trivial number of compiler bugs and standard options that weren't supported. The Intel Math Kernel Library offers pretty good linear algebra performance, too.

Re: older conventions, we had a lot of modern Fortran code that was easy to read and avoided all of the old Fortran 77 nonsense that really confusing to read if you weren't from that era (e.g., the infamous arithmetic GOTO).

However, it was nice being able to still incorporate "just works" code from the 80s that did complicated calculational things that nobody really wanted to touch too much. You know, the kind of subroutine that starts with the comment, "This code _seems to_ ..." I suspect we're not the only organization that wanted to keep that code around but be able to add modern Fortran around and on top of it.
Glade was the best. Drag&Drop, creates a language-independent XML file, which your program loads and populates with events.

I wrote a pile before I realised it was largely irrelevant, especially since the largest platforms are also the easiest to handle.

The easiest one to handle first would be the topic-agnostic platforms. Those also tend to be the biggest ones. Facebook and Reddit as the bigger examples. For these, the answer is simple: Let users create whatever they want and apply rules however they want, but allow the rise of new communities. Perhaps a community forking system can serve as a countermeasure to network effects.

However, the key thing here for these platforms is that the platforms themselves are barred from impeding speech. The individual subcommunities and their respective leaders are not. As such, there's a clear line between the platform and it's community and subsequently the roles and responsibilities of each. After all, the key difference here is that between publisher and platform.

Exactly! I generally agree with the sentiment of the article, and see the importance for issues like healthcare, but that sentence seemed so wrong to me.

"People are living and dying without appearing on any database."

Isn't this, like, a good thing? Now on the other side, of course this is the definition of a first world problem, but not having a say in whether or not I actually want to appear in big techs databases isn't exactly ideal either!
Even in context, the whole concept is a bit strange. If I read something like this, coming from just 40 years ago, it would seem absurd.

I strongly dislike the urge of modern humans to categorize and analyze everything (very non-tech sounding, I know).
Not necessarily, but it might be faster.

Basically you need map data (in form of tiles) and you need a way to show and interact with your map (e. g. Leaflet).

Here is a summary and one way to do it: https://switch2osm.org/the-basics/

Tiles can be images or vector based.
I also recommend having a look at https://openmaptiles.org/ if you want vector based tiles. You can generate your own tileset with this (output is a mbtiles SQLite file based on a open source schema; the schema describes which information go into the database and later can be shown) or download a set of tiles (because e. g. for the world it will take a lot of ressources and a long timeto generate a tileset). There are also servers (like tileservergl or tileservergl-light) that can serve the tilset - not only as vector tiles but also as graphical image tiles.

Letter is open and free for anyone to use, and writers typically choose their own interlocutors.
I initially thought you were the enthusiastic owner of an Alfa Romeo Giulietta :)
A great thing about OSM is that you can improve the data, specifically in your local area so that at the very least it will no longer have spotty coverage of the places you frequent.

I use https://github.com/westnordost/StreetComplete for doing this so I don't have to make the investment to learn the technical details of tags.
I instruct HR to give developers a letter clarifying the statement "In the course of your employment" to not include original software written without the assistance of company materials and outside of company hours.
For anyone looking to migrate to an OpenStreetMap-backed map and location data provider, https://switch2osm.org has a good overview of how, why, and who is offering services.

Respond or email me (also in bio).
Even after all explanations and presented use-cases, I fail to understand how full reading access to a users clipboard by random third-party apps was ever considered a good idea - from apps in the background nonetheless! Only in a world were I, the device manufacturer, write all apps exclusively, maybe.

The moment I draft such a feature my head turns red from all the alarm-bells going off. I sincerely fail to follow the though process here.

And where incentives to game the process are just too high for everyone involved. Ref standard practices like CV inflation, lying about what the role will really be, hiding salary rates from both sides, manipulating entitlements, etc etc.

These problems are as old as humanity and I don't think you can really fix them with code.

The classic way to contextualize anything political is history. Maybe you can read together about a few civil wars. What made them happen, and how they played out.

And as for chopping of hands, am I right to read this as shariah enforcement? Or something secular? The answer will be very different. My understanding is that even Saudi Arabia is moving away from hand-chopping, so the islamic scholars must turning away from the practice. I am sure there must be a few well spoken ones you could read.

If it's secular, then a way to contextualize it is to read about the rule of law: why we have laws in the first place (as opposed to getting together and beating up people we don't like). And why punishments have mostly gotten softer over time.
Most structured data in Wikipedia articles is in either infoboxes or tables, which can easily be represented as tabular data.

Table country:

Name,Capital,Population
Aland,Foo,100
Bland,Bar,200

Now you need a graph for representing connections between pages, but as long as the format is consistent (as they are in templates/infoboxes) that can be done with foreign keys.

Table capital
ID,Name
123,Foo
456,Bar

Table country
Name,Capital_id,Population
Aland,123,100
Bland,456,200
> You start to get into anything that involves drag & drop, you are inviting other programmers to assume you are not good enough with cryptic text.

It's more that drag and drop isn't really good for much when it comes to programming. You can build GUIs with it and some extremely simple tasks like email joruneys, but for anything else visual programming has proven to be pretty poor.

My take is; there is nothing wrong with looking for this stuff but relying on it is short-sighted.

Personal experience of mine is; people who spend a lot of non-work time on side projects and open source bring a specific energy to their work. What they are usually not good at is turning up for work, getting their head down and diligently burning through some work. Instead they tend to be ideas people and leaders.

All organisations need a balance of personality and experience to be effective.

So get excited about Bob because he is an Open Source advocate and regular conference speaker. But also get excited about Alice because her experience is right and when she interviews she is dedicated and detail-oriented.

Yes. not for everyone and everything, but yes. Especially if on foot or bike, but in my area it generally feels like the better map. (and in reverse I'm sure there's areas of the world where OSM is lacking in detail) I basically only use GMaps to search for businesses.

And of course I can use OSM data in many ways I can't use Google data.
