> Medieval villagers were often living on the edge of subsistence. Agricultural surpluses were skimmed by the church and the feudal lords. Bad harvests, banditry, warfare and disease might decimate a village community at any time.

Dwarf Fortress has shown that this would in fact be quite exciting, but it would probably be a lot more niche.

I think it's a misconception that safe handling of input will always cost performance. For Stockfish, I imagine the performance critical part is analysis, where input should already have been parsed.

It is a cellular automaton.

... in mice

Strange choice, given that the game (the port to Source 2 at least) is from 2014, and it's nearly unplayable with a touch bar.

So like a NOP sled?

I imagine this is perfect for climate change deniers. Climate change is very difficult to fight because both undershooting and overshooting your predictions can come back and hurt you.

My mistake, it was an edit link I posted, it should be accessible without Medium, I also opted out of the monetized content thing.

Argh! That's my bad, I can't seem to edit it now.

Yes. It basically turns a reverse engineering task back into regular "forward" engineering, except you are programming with z3's symbolic variables.

Here is an example: https://anee.me/solving-a-simple-crackme-using-z3-68c55af7f7...

You can solve many keygen type reverse engineering challenges with z3.

We have pretty great isolation between programs on iOS and Android.

Interesting to see this and "A.I. Shows Promise as a Physician Assistant" [0] on the front page at the same time.

Looks like those two are not on the wordlist used.

Wow, looks awesome. Has anyone visited, by any chance?

They are mentioned in Turing's Cathedral [0], an excellent book that was recommended here on HN. Here's an interesting quote:

There were two sources of noise: external noise, from stray electromagnetic fields; and internal noise, caused by leakage of electrons when reading from or writing to adjacent spots. External noise could, for the most part, be shielded against, and internal noise was controlled by monitoring the "read-around ratio" of individual tubes and trying to avoid running codes that revisited adjacent memory locations too frequently -- an unwelcome complication to programmers at the time. The Williams tubes were a lot like Julian Bigelow's old Austin. "They worked, but they were the devil to keep working" Bigelow said.

This phenomenon is very similar to the recently discovered row hammer vulnerability of DRAM memory, except it predates it by roughly 65 years.

I already love the bus. The trick is to live somewhere with great public transport.

Here is a relevant DEF CON talk that I found very interesting:

Author is a she by the way.

I was expecting this and started with the comments :)

Isn't the bug in Super Mario just exposing the underlying system's Turing Completeness?

Here is my speculation: you cannot fit enough archers in the relatively small area from where they can still shoot at the same target and cover a significant portion of the sky with their arrows.

It's a little off topic because they do a different thing than in the article, but check this out for some (actually) scary good computer generated examples:

Since it's a draft I'll point out two typos. In 4.1 "if fills" should be "it fills". In 4.3 "1000 to 10" should be "1000 to 100".

I don't think it's as bad as you think. Check out this thread: https://twitter.com/lcamtuf/status/952265416289632256. If shit hits the fan and you end up surviving, your help in the aftermath can be crucial.

Imagine a TCG where you can sell your collection when you want to quit the game. You could buy packs via smart contracts with full transparency wrt. card rarity. The game could add a small fee to pack prices to cover upkeep and creative costs. Some of these fees could be redistributed to players via card/pack rewards. The only requirement (and a strong one) is that the game is actually fun to play, so most of the player base isn't speculating on price.

I think this could give Hearthstone et al. a run for their money.

My grandma has an old Felix artithmometer. AFAIK these are capable of the same things as the Curta but with a less elegant and convenient form factor. It really shows why Curtas are so valuable.

Last time I visited her I used it to estimate sqrt(2) to 3 digits precision. (Result is on the left side https://imgur.com/a/CoEuC)

My guess is because women are already severely oppressed in these societies and it is men's distress that can cause instability because they at least have power.

All we would need is to send a bunch of fuel in parts, dock all of them and fire the strongest engine we have. It _is_ rocket science, but I don't think it's far out of reach if we have the money to spend on resources.
