linschn··on Knuth's Art of Computer Programming, V 4B, has gone into print
We had a very specific use case, where the input was a known composite, and some properties of the factors were known.

Also, while no fast algorithms are known (and may never be depending on if p=np) some are faster than others depending on the properties of your inputs, and choosing the right one can mean saving a lot of time and effort.

linschn··on Knuth's Art of Computer Programming, V 4B, has gone into print
A colleague of mine had invented a technique for factoring composite numbers, that he thought would be quite fast.

I thought a little about it and saw that it would degenerate into sat solving.

I checked taocp and indeed my colleague's idea was in there. Also a faster algorithm was presented in the relevant section. I lended the book to him and we saved around a month of work.

linschn··on Japan WWII poison gas agents still scarring people today
Never mind, I had a brain fart and misread gand father for father, and the sibling comment provided a link to a study showing that indeed, mustard gas has a measurable effect on spermogenesis and can increase the rate of respiratory diseases in the victims offspring.

My apologies.

How hold are you? Even if he had you in his forties, you would be more than eighty now.

I don't know much about epigenetics, but I would be highly surprised if this had anything to do with that.

Same as "smurf", then?

linschn··on SBCL 2.2.8
Launch

rlwrap sbcl

Instead of sbcl directly to get all your line editing niceties.

As far as IDE are concerned, Emacs and the slime module are unbeatable, but it may be difficult to ease into them. There are many tutorials online. You won't regret it.

linschn··on OpenTTD Game Mechanics
It always bugged me that delivering far away gave more money than delivering close by.

So if you have two oil rigs and two refinery, one each on opposite corners of the map, you are better off making the oil cross the whole map than the obviously more efficient way of connecting each oil rig with the neighboring refinery.

Anyway, still an outstanding game!

I use the color of tmux's bar to the same effect.
linschn··on Vets today are like doctors yesterday
Cuba's health statistics are backed by the WHO. They were the first, for instance, to prevent mother-infant AIDS transmission.
linschn··on Ask HN: How to keep my daughter busy while tickling her curiosity
In France, diluting your wine will get you the guillotine ;-)

The legal drinking age is 16 for low alcohol content beverages (wine, beer, etc) ; 18 for all alcohols and tobacco.

At a family gathering or on a special occasion you may get a glass of wine starting around 14 or later I'd say, for most middle class families.

Binge drinking is not as much of a problem as in more northern countries, but binge alcohol consumption is a problem that is being felt at the University level.

linschn··on Crypto Crashed So Hard It May No Longer Be Profitable to Mine Ethereum
That is not how it works. The author of the transaction decides the transaction fee. If nobody has put a high transactionnfee in their transaction, you can't include it into the block you are mining.
linschn··on 2022 Darknet Opsec Bible – Telegraph
Do not ship to your real address, use a dead box. Your vendor may be an informant, or may become one, while your address is in their file.

The rest is mostly good advice.

You can add plausible deniability by running tails out of a USB stick, with a second decoy system which you use often enough to watch questionable porn, in order to justify having it when the police finds it.

linschn··on Price of algorithmic stablecoin UST drops 2% below dollar peg
See for example : https://docs.synthetix.io/synopsis

Basically you mint only a fraction of your collateral (typically 15%), so even a huge downturn of the price won't leave anybody hanging, and you provide a set of incentives for the owners of the collateral to adjust their staking depending on the price you are trying to follow.

It's not too complex, and seems to me way better than trusting tether and Co.

linschn··on Ask HN: What email client do you prefer?
Emacs can reasonably well display html, but when it fails I can open the email in a web browser in two keystrokes.
linschn··on Ask HN: What email client do you prefer?
My email productivity went through the roof when I switched to mu4e (Emacs interface to mu).

I can in a few keystroke isolate the handful of emails that actually need my attention in the hundreds I receive every couple of days.

Org mode integration allow me to reference those that I may need in the future, or that require later action in my to-do list.

My time handling email is now reduced to 20min-2h every two days, in one sitting, my mind feels liberated. I can't recommend this setup enough.

Ambulance, firefighters, etc.
linschn··on Columbia's Sachs Criticizes NATO's Handling of Ukraine
France in a NATO member and did not participate in the Irak war.

This war has nothing to do with NATO. It just happens to be waged by countries which are also in NATO, but the two are unrelated.

And the claim that the Irak war was just (a bullshit claim that only hardcore us republican still make with a straight face) is unrelated to the claim that the ukrain war is unjust.

This is what Anarcho-capitalism would look like in practice.

The ICIJ is a treasure. They are awesome for breaking stories like these.

When they will be able to do it in practice, the protocol will change to use a quantum resistant hashing algorithm.

Trotsky getting an Ice pickaxe to the head should be a hint to you that whatever happened with the USSR was not exactly in line with Marxism.
linschn··on Minitel: The Online World France Built Before the Web (2017)
It's close if you count it in francs, and include all services. This article [0] says that France Telecome gave 700 M FRF to the operators, which means that 1,050 M FRF were collected in 1986 alone.

linschn··on Minitel: The Online World France Built Before the Web (2017)
The number was 12. It was discontinued in the early 2000 IIRC. You would call, get a human operator and could make complex queries like get the number of somebody you knew the sound of the name (but not the exact way of writing it) in a town or around a specific area, and the operator would help you find the number.

Also in France, 15 is medical services, 17 is the police and 18 are the firefighters. By calling 112 anywhere in Europe you'll get an English speaking operator that can dispatch any emergency service.

linschn··on DARPA open sources resources to aid evaluation of adversarial AI defenses
This reads like AI generated text. I literally can not understand what you are trying to say.
linschn··on U.S. State Department phones hacked with Israeli company spyware
Maybe stop funding them, for a start?

Congressional oversight used to be a thing.

Snowden showed the NSA lied to congress. No heads rolled.

linschn··on Avy Can Do Anything
This is a simplification of Unix history, but is in accordance with the fact that the first eager knon programmer) users of Unix were the people typing patents applications at Bell Labs.

See e.g. "unix, a history and a memoir" by Brian kernigan

That's a great example to teach or learn many aspects of minizinc! Great job :)

Have you heard of WWII?
linschn··on Going to Work for the Tor Project
Union workers , journalists, security researchers, IT managers, lawyers, and judges and prosecutors are the professions of people I teach the usage and inner working of TOR to.

They all have legitimate use cases for it.

And nobody has any idea what "most" (according to which metric anyway? Bandwidth, number of connections?) of TOR usage is for.

Of course, have you never heard of credit card fraud?
linschn··on Those who witnessed Castle Bravo looked into Armageddon
France having nuke is definitely about asserting its sovereignty over US interference. Read de Gaulle's biography if you want to know more.
