usrnm··on RPKI now protects 70% of internet routes
It's already happening, you cannot access the websites of many sanctioned Russian entities without trusting a Russia-issued root CA. The fragmentation of the Internet is already in motion
usrnm··on Ask HN: What is the current trajectory of a senior engineer?
I'm almost 40, but nowhere close to being able to retire and enjoy the rest of my life, which is, I hope, going to be at least another 40 years. It's going to be a fun ride
usrnm··on Hittite royal archive found in Turkey
The languages aren't even related. Hittite is an Indo-European language, closer related to English than Turkish
usrnm··on Blood cells from 80-year-old donor become stem cells with molecular age under 20
But what about cancer? The cell still has the same DNA, so it will keep accumulating mutations over its extended lifetime, right?
usrnm··on Citroen revives the 2CV for an electric age
Aren't EVs large because of the battery?
usrnm··on Citroen revives the 2CV for an electric age
Oh, so that's why I cannot see any difference between a Mini and Ford F150?
usrnm··on 3rd Yandex Cloud Data Center Was Hit
My information may be outdated, but the others are much smaller and less relevant
usrnm··on 3rd Yandex Cloud Data Center Was Hit
From a purely engineering perspective, this and the destroyed AWS datacenters in the Middle East show an interesting trend. How will it affect the way future datacenters and services hosted in them are built? Will we see a rise in decentralized systems and much larger networks of smaller DCs?
usrnm··on 3rd Yandex Cloud Data Center Was Hit
They only have 3. At least, the main ones
usrnm··on PVX-001: open-source Covid-19 vaccine starts Phase 1 trial
But that's not what the word "open-source" means
usrnm··on PVX-001: open-source Covid-19 vaccine starts Phase 1 trial
What does it even mean for a vaccine to be open-source?
usrnm··on `123456' password used in Danish CPR data breach
You're contradicting yourself, how can it be unique if only 1000 can be assigned per given date of birth? What if more than one thousand babies are born in the country one day?
usrnm··on What should we tell our students?
Almost all sciences (at least, parts of them) have been also expressed as code, mathematics is no different. It's a tool used by sciences, but it is not itself a science and it is not necessarily rooted in anything "real". Not better or worse, just different.
usrnm··on What should we tell our students?
You must be thinking of physics and other sciences. Mathematics has very little to do with the real world and can be better described as a game, similar to chess, but much more complex. It's no wonder it now went the way of chess, go and similar games
usrnm··on The Mathocalypse
1) Predicting the future is hard, but so far everyone who was saying that it would get better turned out to be right. It is getting better 2) Waymo exists
usrnm··on The Mathocalypse
Contact them again in 15 years and ask if they changed their mind. Could be interesting to see the results
usrnm··on Visa, Mastercard, major banks facing new litigation over 'anticompetitive' fees
> Payment networks are not an easy thing to build or maintain

Then why are there so many of them? I like travelling and almost every country I go to has its own thing going on, often more than one. I lost count long ago

usrnm··on Why were Victorian elites so effective?
Because it was not any different from any other aristocracy in the world at the time. The question the article is trying to answer is "why Britain?" Of all the competing european empires what made that particular one especially successful?
usrnm··on First enhanced geothermal power plant completed in just 23 months
Places with a lot more sunshine. Morocco is a big one. The ones in my fridge right now are from South Africa and Peru
usrnm··on First enhanced geothermal power plant completed in just 23 months
It needs two things: sun and water. Water has been solved and California is doing pretty great, don't you think? Let's take a look at another example: I live in the Netherlands and I like having berries with breakfast. Blueberries, strawberries, raspberries, all kinds of them. And you can buy them all year round in any supermarket, but just for a few months in summer they will have a proud label "made in the Netherlands". Plants had hundreds of millions of years of evolution, millennia of human selection, and still growing berries is not viable here for most of the year. Maybe we will start producing electricity in Morocco and shipping it here one day, just like berries, but producing it domestically using solar will never be effective
usrnm··on First enhanced geothermal power plant completed in just 23 months
Humanity actually has millennia of experience with solar energy, we just call it agriculture. Plants literally are natural solar panels. And you know what all this experience tells us? It varies from place to place, like, a lot. In some places it works nice and in some places it just doesn't.

And yet, when the same argument is made about nuclear, all hell breaks lose
usrnm··on Greenvolt begins building 600 MW/2.4 GWh BESS in Poland
> Industry can electrify or sunset

The much more realistic third option is just moving somewhere else

usrnm··on Barcodes are about to go extinct
Decathlon does it in every country, not just France. Same with Uniqlo and a few others, but it's still only very large chains that can afford it
usrnm··on Loss of cell identity drives human aging: Two new papers
Evolution doesn't care about individual organisms, it's all about reproduction. Our lifespan is enough to raise a few children and pass genes on, so, from the evolutionary point of view, it's adequate
usrnm··on Suits Are Better Tech Than Modern Clothes
> Comfort is the fashion

It, most certainly, isn't, people wear all sorts of uncomfortable clothes and shoes in the name of fashion. Fashion is all about signalling your status and belonging to this or that social group. Suits are simply associated with people most folks don't want to be associated with.

usrnm··on Most data centers refusing to say how much water, electricity they use
> where electricity is abundant and/or cheap

Definitely not the Netherlands then

usrnm··on The internet discovers TLA+. Now what?
That stuff gets rediscovered all the time, the latest example probably being golang
usrnm··on ASML says it sold 'absolutely nothing' in Europe in 2026
China is very much repeating the history of Japan, and while we can argue how democratic Japan was in the second half of the XX century it definitely wasn't totalitarian.
usrnm··on C's Flexible Integer Sizes Were Not a Design Mistake
But not having fixed size integers (or integers tied to the size of a pointer) was. Both can be useful
