Bobblebobble··on A Simple but Nifty Inequality
We can also find the f minimizing the integral of f^2 by considering the Lagrangian: integral f(x)^2 - lambda f(x) + lambda - mu x f(x) + mu dx, then solving pointwise for f(x) to get f(x) = (lambda + mu x) / 2, then using the constraints to get lambda and mu.
Bobblebobble··on Europe's Vaccine Disaster
The parent comment is just saying that a poorly-run vaccination programme results in more deaths than a successful one, everything else being equal. Hope that helps.
Bobblebobble··on Bitcoin breaks above $20k
The carbon footprint is estimated to be 37Mt CO2 per year, similar to New Zealand, and BTC represents close to half of the current global data centre electricity use. https://digiconomist.net/bitcoin-energy-consumption/
Bobblebobble··on Vaccine hopes rise as Oxford jab prompts immune response among old and young
This phase I/II study's primary objective was to learn about the safety of the vaccine, and about whether it causes an immune response. I'm no expert, but I expect the phase III trials in the US and India will include a broader population.

It has been tested on rhesus macaque monkeys.

Yes, they pay a small amount and cover travel expenses.

At the end of the study.

I'm in the trial. Here's the participant information sheet, in case anyone's curious: https://drive.google.com/file/d/1WB5QPmECchlThnem9wcX0PDaKQW...
Bobblebobble··on German push to ban combustion-engine cars by 2030 wins support
Penalizing emissions directly through gasoline and emissions-based road taxes would be a vastly cheaper and simpler way of reaching the same objective. What can be done to make this more politically palatable?
Bobblebobble··on Just shut up and let your devs concentrate, advises Joel Spolsky
I work in an open plan office and find potentially relevant discussions to be the most distracting, so I'm glad that most of these now take place asynchronously over instant messaging. If you've even managed to focus in an airport lounge, or a coffee shop then you know your brain can deal with sounds which are completely irrelevant. Similarly, if it just so happens that people are talking about something directly relevant to your problem, you can join in. The potentially relevant discussions are the most insidious though, because the work of deciding whether they are relevant is sufficient to prevent deep focus.
