YouTube Seems to Be Cracking Down on a VPN-Powered Discount
  • That there are such wild variations in price between countries shows how little that subscription is correlated to any actual costs.

    At best subscribers in richest countries are subsidizing poorer ones, but most probably, Google is just trying to maximize the amount of money they can extract from everyone's pocket. The repeated seemingly random price hikes seem to confirm this hypothesis. It's just the MBAs enforcing terminal stage capitalism and ruining everything that is good.

  • A time traveler's survival guide. The vertical green bars are the only times in Earth's history with enough oxygen to breathe (hypoxia) and low enough to avoid oxygen toxicity (hyperoxia).
  • The partial pressure of oxygen in the Apollo 1 capsule was about 16.7 PSI.

    I had always assumed they just compensated with oxygen pressure to match atmospheric partial oxygen pressure, but I checked and indeed you're right, but it was only that high an oxgen pressure for testing purposes on the ground. Once in flight, they would have dropped it to 5 PSI. It also makes sense as to why that Apollo 1 fire was so violent. Thanks for that learning opportunity ! :)

  • There are 850k people living in La Paz, Bolivia (elevation 3650m) with the equivalent of 13.2% sea level oxygen and they seem to be doing just fine. And granted, the natives of the region display some hemoglobin adaptation, but still... Even Aspen, Colorado sits at about 15% sea level oxygen and I'm pretty sure people don't wear breathing gear while skiing there.

  • Well, this is a post about flashlights, a growing number are using them. And since a type-c charging port is more and common on this type of devices, you don't need to worry too much about how to top them up (though they fit in a bog standard Lii-500 just fine). Anyway i'm not contesting the ubiquity of 18650, I'm just saying 21700 might be the future.

  • Sure, but 21700 is a superior format. It's barely larger than 18650 but thanks to the square-cube law, the stored energy is significantly higher. 18650 is usually around 3500mAh, whereas 21700 is more like 5000mAh.

  • Tesla shareholders to vote whether Elon Musk deserves billions judge struck down
  • Not to defend Musk, but the payout would be in stock options, so it wouldn't really cost Tesla any cash. But that volume of new shares would probably devaluate other shareholders' portfolio even faster that Musk's erratic leadership already has in the last couple years.

    Besides, NO ONE deserves this kind of money. Ever. This level of payout shouldn't be normalized. I mean the guy doesn't even work full time for that company !

  • Giant viruses discovered living in Greenland's dark ice and red snow | Live Science
  • The article you linked to is about suppressyn, an originally viral protein that's been integrated in human DNA and is as far as I know only expressed in placenta. There suppressyn helps fight viral infections by competing with some families of viruses for the binding of a membrane receptor (ASCT2) that these viruses use as a way to recognize and attach themselves to target cells.

    It seems NCLDV infects unicellular algae and protists, with at least some of the family members relying on phagocytosis by the host, and many of them displaying fibrils on their particles. And though the binding mechanisms probably differ between different viruses of the NCLDV family, I really doubt these host organisms express ASCT2.

  • Nope, I looked at DNA length, that's what the kb or Mb in my previous post is about. Kb stands for kilobases, each base or nucleotide being one of those A, T, C and G that constitute DNA. Biologists mesure the size of a genome by counting these bases. Average size for a virus is around 10,000 bases or 10kb (sources say 7-20kb) and they don't get much smaller than 3.5kb.

  • Launch from inside an Apollo Capsule

    Watch the launch of a Saturn rocket from the inside of an Apollo Capsule. Footage has been painstakingly restored, upscaled, stabilized, synchronized with 3D rendering and exterior views, sound recreated from actual launch measurements, and detailed explanations about what each switch, instrument, and gauge does. Truly a work of love.
