I'm excited about this. Bitcoin and crypto use an obscene amount of energy and are basically impossible to ban. A working proof-of-stake system in a non-shitcoin will pile pressure on all cryptocurrencies to move to that system to use

Is there anywhere I can read a technical version of how proof-of-stake work? I'm still confused at what happens if you create a valid block with the Ethereum you stake and then that block doesn't end up being part of the main bran

It's not just distractions: reading from a screen tires me down, and I prefer relaxing while reading some paper. A Kindle works well for this use case, but it's slightly uncomfortable to use.

The Economist is one of the voices of the City of London. They appear centrist until they start talking against public schooling, nationalisation, or government-subsidised utilities.

But isn't there a 5-byte single instruction that has no effect, like `NOP DWORD ptr [EAX + EAX*1 + 00H]`? I thought that multibyte NOPs were executed in a single instruction?

I don't understand the reasoning behind this. Why do you need 5 bytes of unexecuted patch space before the program _and_ 2 bytes of patch space at the beginning of the program? Wouldn't it be the same to have a single 5-byte effec

I'm amazed by how much burnout affects sleep for me. I'm coming out of a very long period of deep burnout. My breaking point was getting to a point where my burnout caused insomnia, which caused a feedback loop with even more burn

I don't understand why execution of a model with the same layers and weights would be different between PyTorch and Tensorflow. Is it a problem of accumulation of floating-point errors in operations that are done in a different order a

Can anyone ELI-CS graduate this vulnerability? My understanding from reading the page is that modern processors process certain data with higher frequency, and somehow that allows an attacker to know guess private keys. However, I don'

Effectively blocking entities from converting currencies in person is much harder than banning inter-country trade. My dear home country made it illegal to trade foreign currency except at government exchanges, which trade only one way and

London, UK: £38/m for 750mbps symmetrical. I'm a bit surprised at how much more expensive Internet is in other places of the UK, including in parts of large cities without fibre optic.

Facebook-in-Facebook later got renamed to Workplace and launched as a separate product, which IMO is fantastic for engineering organisations with >1000 people. Slack doesn't really work at those sizes.
