" A 500W PSU won't necessarily draw more than a 250W PSU " Mostly true, but not exactly. Most computer PSUs are more efficient when operating around 50% of their rated load. So if a computer consumes 125W internally, a 250W P

Indeed. Edge connectors are common on servers with hot-swappable PSUs.

Correct, but I-bonds cannot be cashed out in the first year, and households who can't afford to save more than $10k/year probably aren't interested in having their investment tied out for 1 year. Quite frankly, a S&P 500

"costs so much to transfer btc" That's not true. The typical credit card processing fee ranges from about 1.3% to 3.5%. Average international remittance fees are about 7%. For comparison the average Bitcoin fee is about $1 ri

Think about it this way: with a gas vehicle you wait 5 minutes to refuel maybe once a week, so that's 4+ hours wasted per year. But with an electric vehicle that charges primarily at home you would recharge outside home maybe once ever

My bad, I assumed -cpu-used controlled the number of threads. I retried with "-row-mt 1 -tiles 2x2" (keeping "-cpu-used 8" so the benchmark is comparable to my previous test): the encoding speed is 0.443x of playback spe

On my PC I get .329x of realtime playback speed with AV1, and 4.85x with libx264. So AV1 encoding is 15 times slower than H.264 encoding ! I used ffmpeg "-cpu-used 8" for AV1 (higher than this and I get "Error setting option

"tens of thousands of people" You are off by 3 orders of magnitude. Bitcoin alone validates 7 million transactions monthly. If there were only 50k users, an average user would be sending 140 transactions per month.

Bitcoin alone, excluding other cryptos, transacts 1500 billion USD per year. How much is lost to fraud yearly? 2 billions? That's 0.13%. Does fiat lose less than 0.13% to fraud?

Most worrying is that even an expert like Troy Hunt was UNABLE to figure out the cause of the issue by himself. He "reached out to a friend at Cloudflare" who investigated and found the cause.

The 1-bit palette is a good touch. Making it use parallel(1) is a great and easy optimization. Nice!
