Eh, I tried unfortunately and it's not the same. Especially with video processing, my older Macbook Pro heats up very quickly when using Firefox vs Chrome.

The Defiant is building the essential information platform for decentralized finance. We aim to be the Bloomberg of DeFi, for both news and data.
I wouldn't say PoS security has to be driven by the rich, but by whoever is staking, which people could be staking small like lets say 1 ETH total. The security is derived simply by the threat of having your staked ETH (however much) slashed away.
The point is it mitigates the on-chain attack surface which is still prevalent on PoW. Off-chain attacks are still possible for all consensus mechanism.
I'd further add on to say PoS has the benefit of being able to eliminate bad actors unilaterally. You can't stop anyone from attacking a PoW chain over and over again. Attacking a PoS chain is much riskier as the attacker's stakes are held on chain and are at the mercy of the community who uses the network.
Yup and accordingly PoS devs have explicitly stated this incentivizes stakers to be spread out, and not only on infrastructure but software, as there are multiple client implementations.
Yup: "The Monitor has commenced a preliminary review of the transactional activity of the
Identified Bitcoin Cold Wallets utilizing public blockchain records. This analysis..."
Here is the tracking by Ernst & Young (court-appointed) providing all the public information about these developments. The latest report on 1 March 2019 mentions nothing about a cracked laptop.
To add on to this, you can still improve the code quality while building on it by adding tests as you go, so you can have some solace and also sanity when testing your own code.
Moved from U.S. to Netherlands 6 months ago, and will stay for at least another year.
I moved for work, and I gained a cool new project to work on and new adventures, but didn't have my family, friends, or any familiarity of the culture.
It quite accustoms you to leaving your comfort zone, which is powerful and awesome. And it forced me to really value my relationships, and I found myself deliberately making an effort to catch up and keep in touch with some friends that I really valued.
Depends on the specific implementation. Just because you do it on a blockchain doesn't mean you can't require people to show up to a polling center and sign transactions in person.
With Ethereum, one way to do it is to make the voting weight non-transferable, meaning to give someone else your vote you'd need to give your private key.
It would be of course crazy to do that; like giving someone your bank card and PIN number to give them cash.
> But then you've lost all of the advantages that the blockchain was claimed to possess.
That's a very wide brush stroke to paint. You just have to analyze each use case independently.
In the same example of land registry, just a transparent history is a huge value add when dealing with corrupt government officials. Here's a case study https://s3.amazonaws.com/ipri2016/casestudy_collindres.pdf . Voting transparency even with the government as the part of centralization is a huge value add imo.
Further, even allowing centralization in certain points, like a SpaceX IPO (which should def be centralized), allows whoever holds a share to make arbitrary, trustless mediums and rules of exchange.
> If your code doesn't reach out beyond the blockchain, then there's very little it can actually do.
Asset issuance, voting, wills, identity/reputation systems, land registries.
Fundamentally, a blockchain is just public, transparent immutable data history. Of the above sample cases, all it takes is for the powers to be to recognize the data as a reflection of the real world; which is a barrier outside of the technology.
And sidenote, decentralized oracles will literally tie outside world to the blockchain.
Firefox's history bar is still superior though
