- This is potentially the first real black start of a grid with high renewable (solar/wind) penetration that I am aware of.
The South Australia System Black in 2016 would count - SA already had high wind and rooftop solar penetration back then. There's a detailed report here if you're interested:

- You may be thinking of https://en.wikipedia.org/wiki/Pine_Gap
- They don't all produce separated plutonium, this also includes those that produce enriched uranium, which is also fissile.
The three reasons to produce fissile material are weapons, non-explosive military uses and civilian power reactors. Even many of the weapons states aren't producing new fissile material for weapons these days, they have more than enough.
- The existing ground-station ionosphere data mentioned has been used to detect missile launches: https://www.armscontrolwonk.com/archive/1216884/detecting-mi...
I imagine you could do the same thing with much better coverage using this distributed ionosphere monitoring method.
- The current operating requirements in South Australia mandate around 80MW of gas generation for system strength reasons.
So even on last Saturday when "operational demand" in South Australia reached the ballpark of -200MW (that is, rooftop solar generation was exceeding the demand in the state by 200MW), there was still 80MW of gas in the mix. (The excess was being exported to Victoria).
- There are 5 different businesses that own and operate the distribution network in different parts of Melbourne (AusNet, Jemena, Citipower, Powercor and United Energy).
AusNet owns & maintains the transmission network in Victoria, but it is under the operational control of AEMO.
Dispatch of generation and FCAS instructions is NEM-wide and the responsibility of AEMO.
- Load shedding is quite rare, I believe the only instance recently in Melbourne was on the 13th of February when several transmission towers carrying the Moorabool-Sydneham 500kV circuits were destroyed in the severe storms that day, and load-shedding was required to keep the system in a secure state.
Outages are almost always due to faults in the local distribution network.

- It's hard to believe this was just incompetence - Sierra games were technically impressive for the time, making great use of graphics and sound. But what other explanation is there? If Sierra's goal was simply to prevent casual copying, they didn't have to bother with licensing Superlok at all, a simple bad CRC on one sector would have sufficed. It's all very odd.
Probably the simplest explanation is that management decreed that Superlok was to be used, and the developer tasked with it complied in the most minimal manner possible.
- It is, at least on Linux for ordinary pipe(2) pipes.
I just wrote up a test to be sure: in the process with the read side, set it to non-blocking with fcntl(p, F_SETFL, O_NONBLOCK) then go to sleep for a long period. Dump a bunch of data into the writing side with the other process: the write() call blocks once the pipe is full as you would expect.
To hide the truth, Vice-President of Finance, Alex Roman, outright lied under oath.
This is an injunction, not a negotiation. There are no do-overs once a party willfully disregards a court order. Time is of the essence. The Court will not tolerate further delays. As previously ordered, Apple will not impede competition. The Court enjoins Apple from implementing its new anticompetitive acts to avoid compliance with the Injunction.
