about
Working on stuff at the intersection of cryptocurrency and computer security. Also a Puerto Rico resident (Act 20/22); happy to help people move to Puerto Rico to take advantage of the federal tax exemption, 0% capital gains rate, and 4% business income tax rate. Also FFL07/SOT02.
Chief Security Officer for Evertas Insurance -- the world's first cryptoasset insurance carrier. https://evertas.com/
Previously, CEO and Co-Founder of CryptoSeal (YC S11), which was sold to CloudFlare on 2 June 2014. CISO/Board Member of Tezos Foundation 2018-2020.
Previous startup founder (HavenCo, a couple ecash projects, distributed colo, and DoD/Iraq contracting, new thing), too. Deeply interested in computer security, infrastructure, security, conflict zones, and making the world a better place.
Aside from living on a Caribbean island during crypto export controlled 1990s, I've lived on a tiny artificial platform in the North Sea, plus more reasonable places like London, Amsterdam, Iraq, Afghanistan, Kuwait, and spent 6 months diving in Thailand.

The specific genre of books in your list ("self help") is basically not worth it. Virtually every other type of book is. Good fiction is amazing. Science is great, especially when written at…

I love One Medical as a "walk in" option when visiting SFBA, Seattle, NYC, etc. For the discounted annual membership fee (available through various programs), it's even easier, even if…

You could buy $100m in bitcoin over a few weeks without causing >5% move in the price. (not as a single market order, obviously). Probably not even a 1% move in the price over 2 weeks.

Yes, exactly. I’m sure there are PowerPoint decks specifically around how to pass as a non-IC person...

Another pharmacy one is just saying "brand" vs. "generic", generally.

Interesting USG shibboleths are using the correct acronyms, especially for insider stuff (TDY, "allowances", "authorities", and referring to NSA as NSA and not "the NSA",…

Curious why there isn't a Founders Series on this car -- full prepayment (on a loaded config) for first-in-line position, which helps them with cashflow (a major issue for Tesls).
comment
I agree when SMS 2FA is strictly in addition to a password, and the phone number isn’t used for account recovery (or marketing), it is theoretically no worse than just a password. The problem is it s…

I like the "jenga building" near it, too. (56 Leonard)

What amazed me was just how fast people adapt to crazy stuff. I went to some of the COPs briefly in Afghanistan and once got stuck there for 5 days when it was supposed to be just overnight. Day 2-3…

An extra weird thing for me (as a contractor and pretty "free range", since it was in-theater awarded, and multiple parallel contracts) was I could be at a party in the IZ, then sitting in …

Basing things on soldiers sending letters home doesn't seem generally likely to show a very unbiased view, either. Almost everyone I knew in Iraq/Afghanistan would send only very sanitized …

I've been waiting for Atomic Vapor Isotope Separation (AVLIS or MLIS or SILEX) to let a small group or small state produce their first nuclear weapon basically outside the current nonproliferatio…

My 17 is from some years ago. I fly through NRT or KIX or HND multiple times a year of something interesting at duty free over the past 20 years and tend to buy a bottle each trip to stockpile or giv…

I'd be willing to donate 50mL of Hibiki 17 for science...

I don't want to sit in a priority seat because some disabled/etc. people (including someone who appears healthy but has some hidden health problem, etc.) has to actually ask you to get up, e…

I'd never sit in the last or even last 10% or so of seats on a subway train, as a healthy middle-aged man who isn't escorting a child or something. I'd also be highly suspect of a man …

The Costco in Iceland is amazing. 150% of US prices, vs. 300-400% everywhere else. In Hawaii (cost) and Puerto Rico (cost and quality) it is pretty amazing, too. In Puerto Rico there is basically no…

Most of the bottom ~50% or so of households pay no (or negative) federal income tax, due to low income, EITC, various offsets for children, etc.

I think SpaceX's recent accelerating success has caused BO to change their model a little to be more like SpaceX, which combined with Bezos's deep pockets might let them be a real competitor

If so, sounds like someone from FB Legal and the SEC should have Words with Bloomberg. Wouldn't be the first time they've intentionally maliciously misrepresented/lied about an infosec…

A human can be...20x bigger than a small cat/dog, easily. It's not that usual for animals to eat something that much bigger than them. Much more common among carrion scavengers, but still …

Arguably he did people a service by reminding relying parties of this vulnerability. Both that upstreams might pull their repos, and that upstreams might incompetently run their distribution infrastru…

nato.int is the coolest domain in the world for me.

Most modern rechargeable batteries have fairly sophisticated chemistry and thus charge controllers needed -- you don't just dump electricity into them blindly and then take it out. It's not…

I'm talking about the specific case where www.mosthated.com is sufficiently hated that people will scan the entire Internet looking for it. At some point, you'd use other intelligence to de…

I haven’t set this up in a while but I think you can set up a “fake” cert on the origin to Cloudflare portion and then also pin that cert into Cloudflare, so you get protection against MITM on top of …

Could be a shared hosting platform behind the CDN where the user doesn't have the ability to ip-acl but does have https. Common among low-end users and in the particular case of a "hidden&q…

Did we have any actual confirmation that SIM swapping happened to Jack?

OK, we've now found something even worse than the stupid "best logo competition" for vulnerabilities.
