It would develop into "regions" of space that are entirely matter and others that are entirely antimatter. The boundaries between them would glow as stray particles drift between the regions and are annihilated by contact with the opposing particles.
The fact that we don't see these glowing boundaries in space is evidence that there are not antimatter regions and that the visible universe is almost entirely composed of matter.
Yes, as far as indices go, GIN indices are very expensive especially on modification. They're worthwhile in cases where you want to do arbitrary querying on JSON data, but you definitely don't want to overuse them.
If you can get away with a regular index on either a generated column or an expression, then you absolutely should.
Yes but they also don't seem to claim it does. The use cases they talk about are orbital station-keeping and de-orbiting of satellites. So that implies near-Earth use.
They say it works "by directly converting electrical energy into thrust through controlled electromagnetic impulses", so I assume it's reacting against the Earth's magnetic field using the Lorentz force?
This is generally true not just for Steam. By issuing a chargeback, you're burning that bridge and shouldn't be expect to do business with that vendor again.
I mean, we could be getting closer to that point. According to a recent survey, 26% of Canadians now consider the US to be a “threat” to Canada and 6% consider the US to be an “enemy”. Those numbers is up from 6% and 1% two years ago.
If there's one thing large organizations are good at, it's managing risk. And if you read their post, they've done this.
They're running both source control systems in parallel, switching developers in blocks, and monitoring commit activity and feedback to watch for major issues. In the worst case, if GVFS failed or developers hated it, they could roll back to their old system.
Again, to my point above: there's a cost to doing this but it's negligible for very large organizations like Microsoft.
Microsoft has about 50k developers. When you're dealing with an engineering organization of this size, you're looking at a run rate of $5B a year, or about $20M a day. It's a no-brainer to spend tens or even hundreds of millions of dollars on projects like this if you're going to get even a few percentage points of productivity.
It can be hard to understand this as an individual engineer, but large tech companies are incredible engineering machines with vast, nearly infinite, capacity at their disposal. At this scale, all that matters is that the organization is moving towards the right goals. It doesn't matter what's in the way; all the implementation details that engineers worry about day-to-day are meaningless at this scale. The organization just paves over over any obstacles in pursuit of its goal.
In this case Microsoft decided that Git was the way to go for source control, that it's fundamentally a good fit for their needs. There was just implementation details in the way. So they just... did it. At their scale, this was not an incredible amount of work. It's just the cost of doing business.
It's not unheard-of. My high school (in Waterloo, Ontario) had an internship program like this too, and it's how I got my first programming job in about 2000-2001, at age 15. There were about ten students in my class that got technology jobs of one sort or another that year.
This was the case when I lived in Switzerland as well. My address was just my name at the building's address.
There were 12 units in the building and I don't believe they had numbers. The occupants attached their names to the mailboxes outside the building so the mail carrier knew which box to put things in.
