Yes, good luck with that! Because the current implementation slows it down by 7/8ths on my 8-core server.
Well, that's not true. The interpreter has a global lock, but usually most of the time spent will be in things like I/O calls, that are written in C and thus have no problem with the GIL. You're trying to make it seem like there is no advantage to threading in Python, but that's just wrong.
It wouldn't have saved her. The blood only keeps for ten years and the amount of blood in one umbilical cord isn't enough to treat an adult with.
Between now and a month from now, I'll hopefully be a parent too. We've also had this discussion. Eventually we decided not to do this, because it's just very unlikely to ever help.
The technology is unproven. The amount of blood taken is quite small so it's likely to only be useful in the first few years of the child's life, any later there would be more needed. In the few cases where these cells could be used, donors can often be found. And in a few more years, we should be able to get stem cells from other tissue.
In total, we decided it wasn't worth it.
One useful page for us was this, but it's in Dutch.
And as the man said, getting 85 million barrels of oil per day from the ground and turning them into CO2 is geoengineering. And a consensus to stop doing it seems unlikely.
If this is timesharing, give me my share right now.
