zenkat··on The Steel House Saga
Seems like a perfect opportunity for a brilliant, successful, and slightly eccentric SV multi-millionaire to create the perfect retreat / resort / hideaway in the shell of an architectural marvel.

Just sayin'.

zenkat··on Russia sends troops to Kazakhstan to put down deadly uprising
Which is exactly what is happening in Ukraine now. Their attempts to align with NATO have Putin freaking out, with much saber-rattling & troop movement.
zenkat··on Knowledge Graphs
Not Mark, but I'm one of the original leads on Google's Knowledge Graph.

KGs are great for data integration because they are naturally composable. If you have two data sources represented as graphs, and their node identifiers are in the same range (ie, they have been reconciled), and their edge labels are mapped to the same schema, then you can combine them just by taking the union of all their triples.

This works across different vertical domains -- for instance, you can create a joint film + music KG just by unioning all the triples from a film KG and a music KG, as long as you've mapped the node identifiers to a common namespace (eg Wikipedia). You can then do cross-vertical queries like soundtracks for Will Smith movies, etc.

zenkat··on Ask HN: Great fiction books that have had a positive impact on your life?
LeGuin's _The Lathe Of Heaven_ and _The Left Hand Of Darkness_. Both taught me there are more ways of knowing (and being) than my scientific brain had realized.
zenkat··on Unprecedented North Pole Heat Wave in Progress
I like your optimism. I wish I shared it.
zenkat··on Show HN: Should you buy a house and rent it out?
Try using the model with a very high down payment. At 50% of property value, your gains are equivalent to the 7% baseline. Beyond that, the property makes significantly less than the stock market. If you pay 100% up front, you end up making half what the stock market does.

In other words, the gains shown by this model are coming from leverage, not from the underlying asset. Leveraged investments always return more, but with higher risk. That's true in the housing market as well as the stock market.

zenkat··on San Francisco’s Slow-Motion Suicide
Prop 13 isn't really in the control of SF city residents.

But damn, California ... time to put that wealth-transfer tax for the old, rich, landed elite to bed already.

zenkat··on Making Video Games Is Not a Dream Job
"You can die from exposure, you know."
zenkat··on The Elites of Pueblo Bonito (2018)
This article is "just so" storytelling if the worst kind. Little or no evidence is produced for any of its conclusions -- just assertions that the historical Pueblan people "obviously" must have had a technological elite that desired separation from the riff-raff. It's completely ahistorical -- nothing but fact-free cultural projection.
zenkat··on Ask HN: What do productive people do on weekends?
I am going for a hike along the coast on a beautiful spring day with my wife.
zenkat··on The Bleak Reality of the Instagram Experience
Netflix's documentary on the Fyre Festival makes this case well. The Instagram influencers were all that mattered -- the physical festival was hardly an afterthought.
zenkat··on Continuing our work to improve recommendations on YouTube
Yeah, those Tom & Jerry cartoons are HORRIBLE.
zenkat··on Implicit model of other people’s visual attention as an invisible beam
Which brings up the interesting idea that qi may be phenomenologically "real", insomuch as it's something our brains percieve, even if it has no basis in physical "reality".
zenkat··on The Insect Apocalypse Is Here
Natural selection will do that far more efficiently than we ever could artificially. Insects have a rapid reproductive cycle, and create huge numbers of spawn each cycle.
zenkat··on European parliament committee approves vote on ‘disastrous’ copyright bill
This will encourage centralization to the few big services that can afford to build a Content ID system for recognizing copyrighted content. It will cement the position of big players like Facebook and YouTube, and squash any small startup that might try to compete with them.
zenkat··on Children of the Opioid Epidemic
The article points out that race has a lot to do with how these two epidemics of addiction were portrayed.
zenkat··on System Bus Radio: Transmits AM radio on computers without transmitting hardware
What part of the computer is emitting the radiation? And how is this program manipulating it to generate a song?
zenkat··on Magic Leap One
Website repeatedly crashes on iOS, both Chrome and Safari. Hope the QA on their world-changing AR is better the website.
zenkat··on Inside the Madness at Evergreen State
Why flagged? Read the submission guidelines:

"Off-Topic: Most stories about politics, or crime, or sports, unless they're evidence of some interesting new phenomenon. Ideological or political battle or talking points. Videos of pratfalls or disasters, or cute animal pictures. If they'd cover it on TV news, it's probably off-topic."

From https://news.ycombinator.com/newsguidelines.html :

zenkat··on Inside the Madness at Evergreen State
That's a valid critique of identity politics. The original article is not.

And again, I didn't think HN was a forum for debating these sorts of political / cultural issues in the first place. What does this have to do with science, technology, or startups?

zenkat··on Inside the Madness at Evergreen State
Why is this article considered suitable for Hacker News? It's political fodder, not sci/tech.

In any case, there appears to be many overheated claims around this event, with precious little context. This was a voluntary event, where both minority and white students were allowed to go off-campus for discussions around "identity politics";

zenkat··on Unsupervised machine learning with basket clusters
I'm having trouble deciding if this whole post is a sly commentary on how easy it is to get machine learning wrong.

Beat the market by 10% with k-means clustering and a feature set derived from companies and chemical elements! Hahahaha no.

zenkat··on Have Smartphones Destroyed a Generation?
Despite the clickbait headline, the rest of the article is balanced and well-reasoned, documenting both positive and negative changes. And the graphs at the end (rates of seeing friends, loneliness, having sex) are compelling. Clearly a huge change happened around 2007.
zenkat··on Silicon Valley Women, in Cultural Shift, Frankly Describe Sexual Harassment
And it's creepy harassment when a nerd holds power over you.
zenkat··on In the summer of 1962, the U.S. blew up a hydrogen bomb in outer space
I heard it in Rick (Morty's grandpa) voice.
zenkat··on Is the business of scientific publishing bad for science?
Why haven't PLoS and Science One eaten Elsivier's cake? Their model makes perfect sense in a web-based world. Why are scientists still playing Elsivier's game?
zenkat··on Attempt to Reverse a $55 Million Ether Heist
Etherium's fundamental premise -- "code is law" -- presupposes a general solution to the formal verification of program correctness. This is an unsolved problem (and is likely unsolvable in the complete case).

Put simply, all code has bugs. How can Etherium ever work in practice at scale?

zenkat··on The Shining light of Wikipedia and other disappointments
I asked for the other side of the story. RationalWiki appears to fit that bill. I made no judgments on the merits of either side of the squabble. I trust the readers of HN are capable of forming their own judgements based on available evidence.
