@emil I hope you're not bringing OpenSSL back?

I would rather (or in addition) see something like how git:// leverages SSH. Maybe combined with unix sockets.

You can see for yourself here: http://online.swiftplayground.run

I wrote a Swift library today for output descriptors. It only has one feature at the moment: calculate the checksum.

Porting the Python checksum code from the Bitcoin Core test suite was fairly easy, except for one thing: Swift is very stubborn about strings, and doesn't believe in character count: "hello"[0] will not compile! I had to jump through a bunch of hoops with ranges. But it works.

@FreePietje @stevenroose @harding if your goal is to address climate change, you shouldn't conflate that with a dislike of the 0.1%. Their total CO2 emissions probably don't add up to more than a few Ryan Air flights.

Liberal democracies protect minority rights. That's a feature not bug. Historical attacks on rich elites by majority sentiment didn't end well.

As for offsetting CO2: you can plant trees, etc. But it's true we can't actually fix climate change with present technology.

@stevenroose @harding there's no need to ban something if you can simply tax it to offset externalities. This proposal sounds like pure populism to me.

Putting a price on life is hard, but you can easily figure out what CO2 tax is sufficient. So guns and CO2 are not comparable in this respect.

@stevenroose #climate

1) agreed, though I prefer a single CO2 tax instead of misc. fuel specific taxes

2) I'd prefer to drop VAT on train travel; having each EU country charge VAT on plane tickets is an accounting nightmare for sole proprietors, who have to file claims in each country for VAT refunds.

3)The VAT exempt shopping is usually way more expensive than regular shopping near train stations. More importantly it doesn't apply for flights inside EU.

Testnet blocks have been arriving at a crazy pace during the last ~36 hours. More than one block per minute and lots of stale ones: https://tbtc.bitaps.com

In case you ever need to rename a variable across multiple (e.g. 10) git commits:

git rebase -i HEAD~10 --exec 'git diff --name-only --diff-filter=AMC HEAD~ | xargs sed -i "s/BEFORE/AFTER/g"; git commit -a --amend --no-edit'

To edit commit messages:
git filter-branch -f --msg-filter 'sed -e "s/BEFORE/AFTER/g"' HEAD~10..HEAD

I added my own answer, though it seems to be wrong.

@emzy broken Club Mate bottles make me sad

@waxwing and he even went into details about how to troll these analytics, like using revenue for the bar, paid by a Coinbase user, to buy legal gambling in Germany, and the customer loses their Coinbase account. I assume the customer voluntered 🙂
