I would guess all of these are included in the 4.4 million

Congratulations, you’re an agnostic

Yes, and it requires much more than a single nuclear warhead

A single nuclear warhead is not capable of ending life as we know it, where did you read that ?

Using the same argument, 10 is one symbol. It is the "ten" symbol.

I’m just pointing out that it makes no sense to say that this system allows writing any number as one symbol.

6 is 2 symbols though

Some Hamas leader: "We are an Islamic resistance movement" (although there seem to be worse ones around)

Apparently they like islamic dress codes, going so far as to patrolling beaches to enforce them

They don't like music and dance either

Please point to any source (not obviously islamic propaganda) of Hamas not being an islamic organization. I'm not saying it's what makes them the bad guys, just that it's dishonest to say they have "nothing to do with religion"

Hamas [...] has nothing to do with religion

From Wikipedia:

Hamas, an acronym of its official name, Harakat al-Muqawama al-Islamiya (Arabic: حركة المقاومة الإسلامية, romanized: Ḥarakat al-Muqāwamah al-ʾIslāmiyyah, lit. 'Islamic Resistance Movement')

"Energy contained in coal" doesn’t make any sense. Is it "energy we could get from burning coal if it was 100% efficient"? "Energy we could get from coal if we could use it in a nuclear reaction"?

Coal (anything) doesn’t "contain" energy. We can transform some things, and some transformations produce energy in some form or another.

The upper line of this graph should be labeled "total energy liberated by burning coal" and the lower one "useful energy liberated by burning coal".

Love how nobody got the joke

When DST ends you set your clock back 1 hour (or it does it automatically nowadays) in the middle of the night, gaining 1 hour of extra sleep

The joke here is that the guy did the same for Leap Day, setting his clock back 24 hours and gaining 24 hours of sleep, so when his boss called at 2pm he was in the middle of his ~32h night

A blockchain is only as secure as the amount of work (= processing power) that goes into it. Anyone with 51% of the processing power invested in a blockchain can attack it and essentially steal from other people. For cryptocurrencies it’s a problem that solves itself, because every person that possesses some of the cryptocurrency is incentivized to mine to keep it secure (and to earn some at the same time). The more your cryptocurrency is valuable, the more people will want to mine it and the more secure it will be.

For anything other than cryptocurrencies, you can’t incentivize a huge number of people to commit computing power to secure your blockchain. So you have to protect it some other way, for example only allowing you and some trusted people to write on it. But then it doesn’t really need to be a blockchain anymore, just a write-only database (which will perform better and occupy less space).

If it requires no work to generate a block at the end of your blockchain, any attacker can generate malicious ones.

The power needed to charge mobile devices doesn’t really increase with time, until we invent a totally new battery technology we won’t need more than USB-C to charge phones
