tzumby··on How to sequence your own DNA at home
I would never trust that. Instead I would use Claude to teach me genomics and build the tools to process and interpret data locally
tzumby··on SimpleFold: Folding proteins is simpler than you think
Flow-matching, the technique they describe is incredibly interesting. I studied it in the context of generative AI and found it fascinating. It’s so fitting that a technique that borrows from thermodynamics and uses Brownian motion would go full circle to solve for protein folding.
tzumby··on Hunyuan3D 2.0 – High-Resolution 3D Assets Generation
I’m not an expert, only dabbled in photogrammetry, but it seems to me that the crux of that problem is identifying common pixels across images in order to sort of triangulate a point in the 3D space. It doesn’t sound like something an LLM would be good at.
tzumby··on Back to basics: Why we chose long-polling over websockets
I came here to say exactly this! Elixir and OTP (and by extension LiveView) are such a good match for the problem described in the post.
tzumby··on To Nerves from Elixir
Not sure if they still do, but farm.bot was using Nerves.
tzumby··on New Strategy Could Lead to Universal, Long-Lasting Flu Shot
Brute force is exactly how our immune system works.
tzumby··on New Strategy Could Lead to Universal, Long-Lasting Flu Shot
I think the word you’re looking for is paranoid, not cynic. And yes, you probably are paranoid
tzumby··on Justice Department to file antitrust suit against Live Nation
Cory Doctorow put this all into perspective so well in a podcast I listen to a while back https://www.canadaland.com/podcast/bonus-cory-doctorow-knows...
tzumby··on Medellín's Green Corridors
I just checked and the pm2 levels are as bad as they were when I visited pre Covid (50 μg/m^3). I was there for 3 months, in El Poblado neighborhood and the air quality was horrendous, I would never go back. The depression in which the city lays also keeps all the pollution in place for longer.
tzumby··on Show HN: Streamdal – an open-source tail -f for your data
Congrats on the lunch Dan and Ustin!
tzumby··on Show HN: Prototype for ETH Signing for endorsing Wikipedia updates
This has nothing to do with how much ETH one has. Metamask is a PKI keystone, you’re just signing something using your public key.
tzumby··on Telegram has released user data to German Feds in multiple cases
I agree that they should, the story is that they can. Err, not a story, it’s a known fact that they don’t encrypt communication.
tzumby··on Coffeezilla, a YouTuber Exposing Crypto Scams
I think I shared this on HN before, but highly recommend this podcast: https://cryptocriticscorner.com/

It covers Worldcom all the way up to the recent Terra

tzumby··on Announcing a16z crypto research
I thought there was a date announced on Oct 20, 2022. I can't wait for that to be launched
tzumby··on Announcing a16z crypto research
It's great to see respected cryptographers like Dan Boneh behind stuff like this.
tzumby··on Crypto is an unproductive bubble
The author brings up a very good point about controlling the monetary policy which made me think about the impossible trinity. I have a very basic macro Econ 101 understanding of this, but it seems to me like the dials the central bank used to tweak things like inflation and unemployment are delayed and not precise at all. I think innovations in public ledgers along with things like automatic market makers can tighten the feedback loops so that hopefully one day we have such a high degree of integration that interest rates and inflation balancing can be tweaked in real time
tzumby··on How to Start Disrupting Cryptocurrencies: “Mining” Is Money Transmission
Here are a few reasons why I called it despicable:

- Laundering money in poor countries directly hurt the citizens of those countries because the government doesn't collect the taxes it is entitled to

- Most of the money to be laundered comes from illicit activities: drugs, prostitution, human trafficking. I don't have any citations here for proportions, sorry.

Update: fix formatting

tzumby··on How to Start Disrupting Cryptocurrencies: “Mining” Is Money Transmission
I explained why I think this is argued in bad faith: trying to frame mining in a law framework for the single purpose of killing it vs something like: "ok, this is bad, let's try to fix it. here's how we can fix it"
tzumby··on How to Start Disrupting Cryptocurrencies: “Mining” Is Money Transmission
I love Lawfare and listen to their podcast quite often, but the argument presented is so odd: 1) specifically calling for not introducing new legislation to deal with this and 2) trying to fit mining into a bucket of legislation designed to kill it. This is not in good faith at all.

Money laundering is despicable, specially when it happens at high level. And we have to admit that Bitcoin, ZCash, Ethereum (Tornado Cash) and other cryptocurrencies are facilitating that. But we're getting better at tracking that. After all, transactions are all public and once you can label one wallet address, you can perform all sorts of graph analysis and learn a lot. Contrast that with trying to subpoena banks to follow money trails.

The other aspect of this is that, like it or not, banks are not playing by the rules all the time. See HSBC laundering almost 1 billion for Mexican and Colombian cartels. See Austria’s Raiffeisen Bank enabling former Ukraine's president to steal money with offshore accounts (https://www.occrp.org/en/investigations/former-ukrainian-pre...)

We should absolutely deal with this, but the first place to start is the Bank -> Cryptocurrency (and vice versa) transfers, or as they call them, the fiat gateways. You still can't pay for stuff with cryptocurrencies so ultimately, whoever steals or launders using cryptocurrencies, will need to eventually convert back into fiat money.

Edit: correct typo in first paragraph

tzumby··on It's time for us in the tech world to speak out about cryptocurrency
Yes, this is the kind of discourse I would expect to see around blockchain technology from a group of smart nerds. I can't argue with that, the oldest blockchain kind of failed to prove itself valid in significant ways.
tzumby··on It's time for us in the tech world to speak out about cryptocurrency
Sorry, you have a point. I re-read my comment and it's not very clear. We need two things to achieve the Byzantine fault tolerance:

- a way to ensure that users of the system can't cheat by creating a vast number of nodes and inflate their "voting power" (think of a poll where you can get behind a proxy to vote multiple times because the only security is weather or not the IP voted): this is the hash-cash, proof of work computation that ensures you have real hardware behind your "vote"

- an incentive to mine and secure the network: the cryptocurrency. The amount of cryptocurrency you mined is just a translation of the energy and work you did to secure the network the same way as a banknote is a conversion of X number of hours you worked for someone.

The question, like I stated in another comment, is whether or not this distributed ledger is useful. Let's say we haven't discovered the killer use case for this yet (putting my skeptic hat). Is it fair to dismiss it just because of all the scams related to its current use ? Do we do the same for email just because there's so many phishing attacks that happen on the protocol ?

tzumby··on It's time for us in the tech world to speak out about cryptocurrency
If you don’t believe that there is value in a distributed self replicating Byzantine tolerant state machine, that’s fair, everybody is entitled to their opinion.
tzumby··on It's time for us in the tech world to speak out about cryptocurrency
this = blockchain + proof of work / proof of stake , in my comment. The crypto currencies are a requirement to fulfill the Byzantine tolerance. They need to have value in order for the incentives to make sense
tzumby··on It's time for us in the tech world to speak out about cryptocurrency
What is surprising is how large the number of techies who don’t get this. It’s not about crypto currencies as much as it is about the game theory that allows it to run a distributed self replicating state machine that is Byzantine tolerant - this is the true innovation
tzumby··on PolarDB, yet another open source database system based on PostgreSQL
“high availability through Paxos based replication”. I thought Paxos is supposed to be a CP system.
tzumby··on Ethereum Fork Fails on OpenEthereum
I think this depends on how good the specs are. I agree that if we look at other examples of separate implementations, this would support this argument (see Browsers for example). But on the flip-side, ETH 2.0 - the proof of stake work, released very good specs and now we have working implementations in Go, Java, Nim, Rust and more. All working right now since the launch that happened in December 2020
tzumby··on Europe's Biggest Vertical Farm Will Be Powered by Wind and Planted by Robots
+1 I make pizza using San Marzano canned tomatoes and they taste better than my parents home grown organic tomatoes
tzumby··on Human reproductive cloning: The curious incident of the dog in the night-time
There are, the machinery I mentioned is a lot more complex in humans. The expression of genes is heavily influenced by how the DNA folds (and this is affected by complexes of proteins that Methylate at different locations in the DNA)
tzumby··on Human reproductive cloning: The curious incident of the dog in the night-time
I agree that someone might have tried that, but the real question is, was the clone viable? From what I remember from my human genetics class in uni, cloning is not just about the genes but also about Methylation sites that are carried by complex machinery in the womb (a subject of Epigenetics).
tzumby··on Sweden’s central bank says it has begun testing an e-krona
If you're not using proof of work, blockchains start to look more like distributed storage with an audit trail and immutable row level db constraints

- if it's a Proof of Authority is like a way to deal with who has access to write to the db

- the distributed consensus part is well researched (Raft, Paxos etc)

The only advantage that I can think of is interoperability: you will be able to communicate with the public blockchain for point in time "backups". Also, building your internal smart contracts you can use an existing language like Solidity.
