My understanding was that a large tranche of that $10B consisted of Azure compute credits, not actual cash.
jkhdigital··on Cryptographers solve decades-old privacy problem
There are two use cases: (1) when the computation is proprietary so the user can’t run it, or (2) when the user doesn’t even want to trust their own hardware.
jkhdigital··on Cryptographers solve decades-old privacy problem
It would be hideously expensive due to the compute required and the total inability to monetize the data. Some people value their privacy that much; most don’t.

Whatever Numerai has done to their data, there is no indication that they actually transformed it in a way that would hold up to a theoretical cryptographic adversary.
jkhdigital··on Cryptographers solve decades-old privacy problem
Still doesn’t quite justify homomorphic encryption if the computations involved are mundane (like tax calculations). The true use case is when the computation itself is proprietary, so that users don’t want to reveal their data but the provider also doesn’t want to divulge their algorithm. This is why ML models or finely tuned search engines are the examples most commonly cited, but of course those are also far outside the scale that could be achieved.

There is no side-channel because FHE effectively considers the computational hardware itself to be the adversary.
jkhdigital··on 37, the median value for the second prime factor of an integer
It is another accident of evolution that we ended up with 12 finger joints, allowing one to count to twelve with a single hand by tapping the thumb on each finger segment in turn.
jkhdigital··on Validating Data in Elixir: Using Ecto and NimbleOptions
Back in 2018 I took a graduate level distributed systems course from a professor who spent most of his lecture time rambling on about how we’d be better off reading HN than our textbook. There were no exams, only four projects which involved implementing various classic distributed algorithms (gossip, chord, etc.) in Elixir.

For what it’s worth, Elixir is now my preferred language for personal projects, although I still haven’t had a chance to use it professionally.

For all the truly deceptive and harmful propaganda that spews forth from government mouthpieces, it really boggles my mind that this is the one that “media watchdogs” decide to pounce on.
jkhdigital··on Children of married parents do better, but America is moving the other way
As with nearly all of social science, we can’t really run the controlled experiments necessary to determine if this is a causal relationship. Just because it looks like a “monetary problem” does not mean that throwing money at it will fix anything.
jkhdigital··on Children of married parents do better, but America is moving the other way
The article really doesn’t answer that clickbait headline, but it seems analogous to “Why Jews earn so many PhDs”. It’s mostly culture, which is a tangled and recursive process that can’t be deconstructed into some government funded social programs.
jkhdigital··on Children of married parents do better, but America is moving the other way
Funny you mention that. I have four siblings, raised together in a (mostly) traditional family, and all five of us have children now. The only one who is not married is my schizophrenic sister.

However, my late aunt was schizophrenic and stayed married for her entire adult life, so who knows.

Pathologizing dissent is not going to change anyone’s mind.

Half of humanity is not going to die from climate change. It is going to die from other people who consider humanity itself to be a pox.

Also, birth rates are in terminal decline pretty much everywhere except Africa so don’t worry, we’ll control our population on our own.

Can you cite the text of the law which motivates your hypothetical felony?
jkhdigital··on Executive Function Theft
Bingo. The corporate buyers of FSA plans are not the consumers. Misaligned incentives.
jkhdigital··on Executive Function Theft
I think the questionable assumption is that people have some sort of fixed, intrinsic capacity for decision-making that is somehow distinct from other stable personality traits.
jkhdigital··on Executive Function Theft
My childhood household had a pattern where the dishes would be done within an hour or two of eating dinner, sometimes a bit later, but of course always before everyone goes to bed.

My wife sometimes does most of the dishes before she even starts eating. If I followed the customs of the home I grew up in, my wife would end up doing the dishes every single meal before I even get to the sink. Obviously I have learned to adapt to the situation, but my point is that it’s a bit unfair to characterize every mismatch in expectations as evidence of abject filth and slobbery on the part of the husband.

jkhdigital··on Executive Function Theft
Exactly. Conscientiousness is a personality trait and those who are lucky enough (yes it is highly correlated with positive life outcomes) to have it in abundance would do well to calibrate their expectations of others accordingly.

Another note:

The “inconsistent” naming is actually a way to distinguish between guard and non-guard functions: is_map can be used in guards while empty? cannot.

jkhdigital··on We need scientific dissidents
I also felt it was the most likely explanation from the first time I read about it (March/April 2020) but even if it was “just one hypothesis” here’s the thing: if true, it has profound implications for the future of humanity. It’s not like this is just an academic question about what killed the dinosaurs. It doesn’t matter whether it can be proven; the fact that we consider it in the realm of possibility means we need to figure out what can be done to ensure the next “hypothetical” leak isn’t even worse.
jkhdigital··on We need scientific dissidents
No the argument is nonsensical on its face. A lab leak supposedly recycles those tropes but emergence from an unsanitary wet market does not?
jkhdigital··on We need scientific dissidents
It was not just “common sense”. I was reading in-depth articles about the GoF line of research and all the characters involved (Ralph Baric, Shi Zhengli, etc) back in March/April 2020. Basically the entire body of circumstantial evidence pointing to the lab leak hypothesis was known and reported within months of the start of the pandemic. Every in-depth article written since then has been mostly a rehashing of what various bloggers and alternative news sites had already published.
jkhdigital··on The inability to simultaneously verify sentience, location, and identity
It’s all the same problem that Ken Thompson identified in his classic Turing lecture: there is no way to reliably identify Trojans.

jkhdigital··on Cognitive AI for ADHD
Yeah I tend to agree, my ADHD is an existential problem only because I have a family to support and it tends to disrupt the flow of income. You know, by getting me to change careers like four times before age 40…

Your last point is the one that really matters. No woman wants to have a child out of marriage, and marriage rates continue to fall while the mean age of first marriage is almost 30.
