Wow, hackernews is a cesspool of self-serving "intellectuals". We're in the middle of a pandemic, which already killed 27 thousands people. And the #1 post is privacy act? Can't you guys admit that you didn't come up with video calling company worth 37 Billion dollars. Maybe it's worth talking the positive impact on Zoom during this crisis.

Not very good to be honest. Nothing about schedulers, bootstrap, and most of it is very general information. it doesn't give actual clear picture how everything comes together, and it is very system specifics (unix). CS should be agnostic to any system architecture. You do cover binary , but the more fundamental question what is the foundation of binary mathematics. It goes back to Turing machine, and how transistors are built and how you compose them into bigger units, and then you talk about CPU architecture, the adder, multiplexer, the PLU, etc.

Does it matter if it is signed or unsigned int or char? Bitwise it contains the same amount of information. That's the most important thing.

How Bitcoin Ends 7 years ago

Aside from the flaws of the article, there are something to be said about how centralized bitcoin has become. Most of the bitcoins are held by centralized exchanges, or "qualified" custodian (locked up in ETF and other exchanges). They essentially act like centralized banks, the exact thing we're trying to avoid. The only saving grace is we can send to native wallet, giving us some freedom from the institutions.

I think is bad for instagram and whatsapp credibility. Facebook has the lowest credibility among the 3 brands. Makes no sense. People literally say i hate fb, thats why i use instagram. And people say, I hate fb messenger, which spies on them.

This one has lots of potential. TDLR, this one has built in governance to allow update to the cryptocurrency, which both bitcoin and ethereum had issues with. Bitcoin has scaling problem, and eth had to fork. Ironically, cryptocurrency purpose is the decentralized but the core team retains too much control, which exactly what they're trying to avoid. I'm planning to fund ICO.

Good for educational purpose. But for practical purpose, this may have unpredictable issues under different lighting conditions, debris, broken markings, etc.

Great to see they finally unveiled Viv. They've been working in stealth for a few years. Six months ago, I met the team for interview & offered a position as Mobile Architect. I declined the job for reasons unrelated to Viv. I met the technical cofounders, Adam Cheyer & Chris Brigham. It was just awesome to talking bunch of guys who made original Siri, and personally worked with Steve Jobs. You can read up on Adam, not only he's an AI God, but he's a super nice guy. If I were to bet on one AI company, they would be it. Like Kittaus eluded to, it's going to take some time to see what use cases ordinary people use for but it will be exciting. Best of luck to them.
