What I'm curious is understanding how people can arrive at radically different conclusions and thought processes when operating in the same world and same society. There seems to be a parallel thought process and definition of words th

You can start with the Ethereum whitepaper. https://ethereum.org/en/whitepaper/

You might be interested in Proof of Stake based blockchains then. They don't require the crazy electricity. Check out Ethereum, Polkadot, and Cardano. I personally shy away from investing in Bitcoin in favor of those. Bitcoin also do

Well, there are alternatives consensus mechanism that look just as good if not superior like Proof of Stake that don't require all that electricity.

They both require large financial investments don't they? And both PoW and PoS have pooling options if you want to invest less. I'm not seeing much difference in terms of accessibility. In theory PoS is easier because PoW requir

It's already being done. There is a ton of financial transactions in the DeFi space happening on Ethereum right now and other protocols on other chains are rapidly being developed and rolled out.

They are known as "proof of stake". The way it works is that "validator" nodes confirm the blocks. The validators are randomly chosen based on the percentage they have staked. You stake by owning the coin and locking it

A lot of the interest in BTC is driven by media and the fact that it is the oldest and original blockchain solution. The newer solutions like Ethereum, and even newer like Cardano and Polkadot are game changing because they use proof of st

A transaction or a block? Multiple transactions are recorded in a single block. The massive computational power is used to certify and lock down blocks at a time, not individual transactions.

Unless BTC changes to a "proof of stake" model like the majority of other new cryptocurrencies that are out there, it will see a large chunk of its marketshare replaced. There's already a big shift from BTC to more technicall

I wonder what is different in the Second Edition. I own the first and absolutely love it. Also loved the nand2tetris course.

We have been seeing deplatforming happen more and more these last few months. Seems like this is going to accelerate a decentralized Internet. It's going to be exciting times with a lot of societal questions and problems to be answere

For something about HCI why is the font so ridiculously oversized? Very hard to read.

I left the bay area in 2020. Neither of those 2 really were on my mind. I haven't heard any horror stories about tech companies trying to enforce any kind of non-compete outside of CA so it never really popped in my mind. Biggest iss

I would much rather see something more decentralized. It seems like politics is increasingly looking like whichever party is in power uses their power to get more power. There is definitely an argument to be made that the Internet is so mu

Sure it wasn't the sole cause but it was definitely a strong contributing factor. Listen to the interviews of the people that were there. It's human behavior when people don't feel like they are being heard and understood th

In order to be a free country there must be freedom, even if you don't like what other people say. This is a dangerous precedent. We are rapidly getting to the point where elections are not based on merit of candidates but by what the

Is there any source that has a bunch of the claims and refutations to it? Just saying fraud doesn't exist doesn't help calm the outrage of those who believe it was stolen. Also based on how partisan the impeachment was it is like

This is really good advice. Myself personally, I have been programming for decades as well and struggle with the curse of knowledge. Curious what other people do and what struggles they have had. Having spent time studying Category Theory

What are the pros and cons of this technique? Seems like this pushes a lot of the rendering compute power from the client to the server. I guess that is good for low power devices but now you need more powerful servers?

When something happens at the federal level it affects everyone. Someone in Texas who is conservative is going to be upset about a law that is forced on them that they don't like. However, if that law is only happening on CA and has

This is true for the most part. But having the CS knowledge allows you to create much more efficient solutions once at scale. I've personally revamped core parts of a product at previous companies to be over 1,000x more efficient just

I use category theory quite frequently when doing functional programming. Unfortunately it is not taught in CS programs AFAIK. I rarely implement any tree kind of algorithms other than a simple tree visitor. An understanding of time/

This is a good starter list for the more Computer Science skills but I see little in the way of practical skills. It's definitely nice to have these skills but let's be real, you aren't going to use them on a daily basis. I

This bug write-up reads like a suspense novel. I cheated and jumped to the ending. It's finding bugs like these that give you an immense sense of satisfaction for discovering it once you get through all the frustration. Well done!

Well, the USA was supposed to be a union of states where they could more or less govern as they see fit based on their own ideology but come together when they need to. But unfortunately the Federal government has gotten involved in far to

Funny enough, I actually agree with this, at least from an economics perspective. I'd much rather get rid of the income tax and have higher property taxes. That seems much more efficient to me.

Ethnically maybe. But in terms of diversity of opinions and tolerance of those opinions it's actually much worse that other places in the country I have been.

It's people telling me what is good for me that is another reason I left.
