One of the most interesting innovations in the Ukraine war is their internal market place for drones, letting each drone group decide which drones they want to procure and use in battle.

It is not a top-down decision, production and supply as other armies use for their weapons logistics.

Supermarkets often have so low margin that building for the 98% of customers means that all of the profit has disappeared.

Profit is often at the margin.

The KISS version of regulation would be that stores are not allowed to use the word "buy" when you don't get full ownership and must use the word "license" instead.

Also it should be marked clearly that the company can rescind the license at any moment without giving any reason why.

Denmark does not have a problem with age. It has gone the other way: members are younger today than in the old days. Graph: https://www.ft.dk/-/media/sites/ft/billeder/infografikker/ta...

Average age is 44 years !!!

The oldest is 72. Youngest is 23. Majority is 30-54. https://www.ft.dk/-/media/sites/ft/billeder/infografikker/ta...

Perl has the negated if statement:

    return unless fooOK;
    return unless barOK;
    return unless bazOK;
    # do something

> trains about the same amount

The nice thing about trains is that they can run on electricity.

It does require investing in overhead wires.

Problem is that PostgreSQL does not support LIMIT on the DELETE command.

I have no idea why, it seems such an obvious feature for supporting large databases.

It is like writing novels: it is not the spelling or typing on the keyboard that is the bottleneck.

It is always the creative world building part.

The main criticism of the Harry Potter books are not spelling or sentence structure, it is the plot holes and contradictions in the world build.

The same holds for software.

This is a very nice and fresh page layout.

Good trick is to prefix all such keys with magic, i.e. a couple of letters that identify type type of key.

Then it will always be a string and you will be free to change the format/type of the key in the future to UUID or whatever you like.

I'd really like a collection of unit tests for parsers. There is a lot of details that can differ between parsers.

E.g. in "Section C" the resulting KeyThree is "value 3▵▵▵▵▵▵▵value 3 continued" where each "▵" symbol is a space.

I think most people would expect a single (or no) space here.

I would guess that most software would strip the comments in SectionC or rearrange the output so that it will result in a diff even when nothing in SectionC changed.

So if you edit the file by hand in the same style as shown in the examples, then most editors would not be able to make a minor edit without making a large diff as many sections would be formatted differently.

XML would have the advantage of having a grammar so we could validate the config files.

It would also make it much simpler to make good GUI editors for the files instead of the Notepad approach most unix config files take.

In Danish: https://danskebank.com/da/news-og-insights/nyhedsarkiv/press...

TLDR: power supply failed completely and DB2 failed running recovery operations due to multiple old/existing software bugs.

A Danish bank found out that this can bite you in the ass.

When you hotpatch the system for years then you have no idea if the system can boot up or it will fail somewhere in the booting process.

i.e. you can only trust what you regularly test.

iOS 26 is very late to have acceptable performance in the framework that Apple promotes as what you should use. It should have had good performance from the day it was introduced.

WebKit have had great performance for a very long time now.

Why would any startup dare to use tech that only now got fast? Why not go with the battle tested WebKit?

It is also much easier to develop and test html pages than Apple specific tech.

Notes in the toilet were mostly for passing to other students.

In many exams we were allowed to bring our own notes. Those are unusable if you haven't learnt the material, as you then don't know what to look for.

But a small note with a math solution could help another student a lot.

> plastic everywhere.

plastic will still be everywhere. The major catastrophe that could happen is for evolution of plastic eating bacteria like the creation of (dead) wood eating bacteria. Look at all the plastic containers etc you have in your kitchen and imagine it's just gone.

> social media as news

Mainstream news isn't going to get any better.

> teflon

teflon has gotten a lot better since it was introduced. It will stick around.

> fossil fuel cars

will be seen like rotary phones: they will not understand why they are so cumbersome or why so many people had resistance against electric cars. It's like electric lights versus living with only oil/candle lights.

I think a near term would be: "you had to go to a cinema to watch a movie?"

It's a very different world from the exams I had in Denmark, both uni and high school:

* all exams were proctored

* the proctoring were done by external people hired to do this.

* you could not leave exam for the toilet without asking first and then being followed out by a watcher, which then would follow you back and check the toilet afterwards for notes.

* you were never handed back the papers you handed in.

* responses were judged both by your own teacher and by an independent teacher from another institution.

* you must use ballpoint pen (permanent) and not pencil. Pencil responses were ignored.

Today the studens are even handed Faraday-bags that their phones and smart watches must be kept in during the exam. Full instructions for exam watchers for a business school: https://www.nielsbrock.dk/da/om-niels-brock/til-eksamensvagt...

A lot of boomers thinks windmills are against the natural order and will end the world.

Also solar parks are just the most ugly thing in the world. They must be banned.

> not actually needed

What you need is more that enough bandwidth.

Think of the difference between a highway with few cars versus a highway filled to the brim with cars. In the latter case traffic slows to a crawl even for ambulances.

It seems like it was just cheaper and easier to build more bandwidth than it was to add traffic priority handling to internet connectivity.
