Trump being into fighting air pollution is a new take I have not heard before. Policy-wise, his administration was vehemently anti-regulation[0] and rolled back many air quality regulations protecting us from toxic substances like coal ash[1], which contains heavy metals like mercury and arsenic.

The most egregious example in my opinion was the attempt to end California's legal authority to set its own, more stringent, emissions standards[2]. The edict was even opposed by a majority of automakers.

Luckily many of these rulings have been rolled-back or are in the process of being reversed.

Air pollution even from tires and brakes, let alone from gasoline, is a large health problem and should be discussed more.

It is a shame that Zoom appears to have killed Keybase. Having a safe, secure identity management system to link social media and software development accounts is currently a gaping hole in providing trust online. ENS is useful for crypto wallets specifically, but there is still missing a general identity management solution.


I've used IPFS[1] to store and host files completely separate from cryptocurrency. IPFS is a major backbone of Web3 tech, and is responsible for enabling much of the current NFT craze because IPFS is free. The same company that made and maintains IPFS also created Filecoin, and the fact that the two are completely separate projects to the point where I can and have used IPFS for free without having any knowledge of or owning any Filecoin speaks volumes. Judging from some view of the Web3[2] stack, I can create a decentralized application that exists entirely through p2p storage without ever actually having to incorporate a blockchain or cryptocurrency, and this can still be considered Web3 technology.

I think that is a great analogy. If you view Bitcoin on the main blockchain as M0 money supply, then side channels like the Lightning Network and other centralized payment processors that have been popping up can be viewed as M1 and more commonly M2.

If Bitcoin's original thesis of truly decentralized P2P cash still holds, then it should be viewed as an M0 money supply. Financial services and products build on top of and separately from the main chain make sense as analogues to reserve banks and payment processors that do not handle the majority of transfers in physical cash.


I don't like that analogy. Unlike M0 and M1, every BTC on the lightning network represents one BTC on the L1 chain. The L1 funds are locked in order to participate in L2.


Unlike current USD, but like USD before Nixon abolished the gold standard, right?


That's a promise that Lightning makes and that you can check in their code today, but it is not a fundamental guarantee the way that the bitcoin blockchain offers guarantees.


Sure, if you changed the code of lightning then it would work differently. If you changed the code of the L1 chain it could work differently too. How are those guarantees different?

Calling it a promise makes it sound like there's counterparty risk and you're relying on them not changing the code. Changing the lightning code would have no effect on your funds locked into lightning using the old code.


From my understanding of previous talks on this, a fair amount of HFT's and trading firms use Java. The trick is that the trading day is a well-defined window with clear starts and stops. So if you load up your server with huge amounts of memory, you can get away with never calling GC during the trading day. The GC can be paused until after hours or just kill the program and start it up before market open the next day.


One solution I had been dying to implement is the Erlang style of letting a Kubernetes POD OOM, and just respawning it. If the app performs well right up until it runs out of memory, I see no reason to have a GC turned on at all. (obviously there ARE reasons, I just wanted to try this approach)


I'm curious to know what difficulties you found using Scala and your experiences transitioning to Kotlin, if you are willing to expound upon it.


I am interested, my email is in my profile if you would prefer to send the links that way.


Sent. Thanks we understand it’s extremely easy to blow off an idea that sounds like “legit ICO” especially when the SEC warns to look out for that language.

If you don’t find all the law to boring and get through it we would love feedback and/or questions.
