22/29 = 76% in some form of "yea"
That feels like "rough consensus"

(2) One of the goals of this project was to layer ZK on top of current identity standards that DMVs already issue, so that gov orgs don't have to change what they currently do to support the strongest user privacy. One example format is called Mdoc.
(3) The user holds the identity information on their device only. No other copies. The user's device makes the zkp proof on-device. This was one of the major technical challenges.
(4) The relying party (eg a website) runs the zk verification algorithm on the proof that is produced by the device to ensure soundness.
(5) Yes, the user can use any compatible implementation to produce the proof. We have open-sourced our implementation and we have a spec for the proof format that others can also reimplement.

That doesn't explain the way this scheme works, but it's a nice start.

abhv | 2 years ago | on: We don’t need a new Twitter
"Thousands of scientists are cutting back from Twitter"
Essentially, a survey published in Nature about twitter usage among scientists dropping, in part, because of the phenomena mentioned in this New Yorker article.
Eg:
"Žiga Malek, an environmental scientist at the Free University of Amsterdam, mentioned in the survey that he had started seeing a lot of “strange” political far-right accounts espousing science denialism and racism in his feed. He has to block them constantly. “Twitter has always been not so nice let’s say, but it is a mess right now,” he said."

* for traffic see the small note "all values rebased to 100" they are likely hiding the significance of the increase
* for the app downloads graph: does the 30x gap say anything? are there seasonal reasons that can explain why every Jan1--Feb4 has more DLs than Feb4--Mar11 ? e.g., new phones?

From that, about 1.3% + 5c per tx go to interchange + assessment fees.
This leaves about 1.6% + 25c for the payment processor.
14.3 on 816b is about 1.7% which is consistent.
On 1T, that means about 17b in revenue.
Lets assume they have 7000 employees (i've seen 6000-8000 in searches). As rough estimates, these SFO-based SWEs + knowledge workers cost 1m/yr on average (which includes their total comp, insurance, federal + state taxes, and operating overheads amortized over all employees). So their cost of labor may be around 7-8b/year.
They may have other acquisition and marketing costs, but it means the co can feasibly be earning >8b before taxes, depreciation, amortization, etc.
That number could justify a 80b valuation.
If their current round cap is 55b, then my #s on costs are off, or the multiple has dropped to 6-7. Please debug.

abhv | 3 years ago | on: The sad story of Heisenberg's doctoral oral exam (1998)
He worried; his advisor begged the hw professor to give him an oral exam in place, because he was a promising candidate with a faculty job already lined up and incredible published results.
Unlike Wein, the hw professor was happy to oblige and created a basic oral exam, suspecting that the student was destined for greatness.
The student desperately tried to cram the hw textbook, but his heart was simply not into the subject. He did however, get the main point of the entire field.
This is when the funny part of the story begins. If you know this person, you know that he is remarkably clever, charming and convincing. He tells me that the hw professor had prepared a small number of questions, all beginning with something like, "explain how a XXX works in a YYY architecture", and that he really didn't know any details of XXX.
He started by copying a basic diagram of a processor onto the board. He kept his answers short, he began each with quizzical look indicating that the question was obvious, and all answers included a remark along the lines of "Obviously, its for performance!" In some cases, while facing the professor, he would point backwards to a spot between components in the diagram. He would slowly move his finger to different areas based on the look on the professor's face.
The hw professor was amused and obviously passed the candidate!
TLDR: don't let classes get in the way of your education.

We are a family of 5, and in Switzerland, that means 2 hotel rooms x 3 nights. Staying in Zumthor's cabin is certainly a splurge, but marginal utility of staying in a special place well exceeds marginal costs.
Also, if you are irrationally nostalgic like me, the renting experience felt like how airbnb felt in 2011...before all the bad experiences which have swamped it in the last 5yrs

Lesson for me: perfection isn't necessary for the experiences I want from exceptional architecture.
abhv | 3 years ago | on: Staying in Zumthor's Swiss Wooden Cabin
-- Like everything in Switzerland, it was easy to reserve spots online. I think we went on a Monday. Therme Vals is a well-designed space, and the spa experience includes ~18 different zones and temperatures. Some of them are gimmicks, but nonetheless delightful play of space, sound, temperature and texture (stone).
Our family isn't into the pampering-spa experience, but I think all of my children can still describe that place 1yr after---worth it for me.

I think the beams were 6" of solid wood.
2-- Alpine woods are incredible. The table top in that picture was unfinished. The instructions of the house say that if you spill something, you just wipe it off with a damp rag.
I was terrified of eating fondue or jam-and-bread with my kids there, thinking we would mess up his table. Fact is: we did have spaghetti and spilled sauce, and the damp rag treatment didn't leave any stains.
Zumthor also seems to have a big family and there is evidence his grandchildren operate like normal kids in that place.
My son gave me a wooden box carved from alpine wood, and the maker intentionally kept it unfinished. The maker told me that the oils in the alpine wood provide a natural protection; +1 yr later and that box sits in our kitchen holding salt. It has developed a natural patina despite lots of mid-sautee grabs, opens, and pinches.
TLDR: like cedar, ipe, and other special woods, I think the wood used to build this house will last a long time in that natural environment.
