And California would be sucking pretty badly without Silicon Valley too.
Without Silicon Valley, California would still have Hollywood, which adds a lot to the state's economy. California would look pretty bad if you took out San Francisco, Los Angeles, and their surrounding areas, but most states would look pretty bad if you took away 75% of their population.
Actually, CMD would be in theoretically worse shape if evaluated apples to apples. However, powershell *puroports* to have security features like execution policies and signing, so it draws more scrutiny. Those are pretty much useless in practice because a cmd script is not subjected to that scrutiny and can just modify the executionpolicy of powershell at will if it really wanted to do some nefarious stuff that required powershell (though they could easily use pretty much any language they want).
My understanding is most server farms are connected to dedicated nuclear power plants anyway, so power consumption isn't an issue. Heat dissipation? Yeah, that might be an issue.
Heat and power are the same issue. The conservation of energy means that power in is power out, and the power out is heat that needs to be dissipated. A rule of thumb for data centres is that every dollar you pay in electricity for the computers, you need to pay another dollar in electricity for cooling. If you want high density, then you hit hard limits in the amount of heat that you can physically extract (faster fans hit diminishing returns quickly). This is why AMD's presence in the server room went from close to 100% to close to 0%: Intel was much better at low power.
Intels problem is that it cannot sell FAB time because they are vertically integrated
This is true. Intel will fab chips for other people, but they've had very few customers because everyone knows that the priority customer at Intel fabs is Intel and if yields are lower than expected it won't be Intel chips that get delayed.
Intel builds a FAB and runs its next gen chips off of it for a few years, then they are stuck looking for something to do with the FAB when it is no longer current-gen
This is simply not true. Slashdot likes to think of Intel as a a CPU vendor, but that's actually quite a small part of their business. They make a lot of other kinds of chip and a great many of these don't require the latest and greatest fab technology. This has always been a big part of their advantage over AMD: they have products that will use the fab for 10+ years, so they can amortise the construction costs over that long a period.
TSMC's revenue is now approaching Intel's, and unlike Intel they can keep all their FABs busy making money, so the outlook for Intel is grim without a serious restructuring, which they are doing (see recent massive layoffs, and bullshit marketing about their new "cloud strategy")
This is the important part and is where the ARM ecosystem has an advantage over Intel. No single processor vendor has to compete head-to-head with Intel. As long as the total size of the ecosystem is large enough, the foundries can invest in process improvements.
They may not do as well in the mobile and Server spaces
When you put it like that, it doesn't sound too bad. Until you realise that mobile is the largest overall market segment, and that mobile and server are both the highest-margin and fastest-growing segments of the market.
AMD had a unique market opportunity to build up a good manufacturing base w/ quality fabs for their CPUs, but didn't. Intel gave top priority to their fabs, and are the standard
AMD spun off their fabs for precisely this reason. Building fabs is insanely expensive and the only way to do is to amortise the cost over a lot of chips. Even at its peak, Intel was producing 4-5 times as many CPUs as AMD and had a load of lower-end products (e.g. network interfaces) that they'd start using the fabs for once they were a generation old. There was absolutely no way for AMD to compete head to head with Intel in fab technology, because they couldn't get the economies of scale.
This does; however, highlight just how bad Intel is at CPU design. AMD has been able to achieve rough parity for decades (and been ahead a couple of times, with the original Athlons and Opterons) in spite of always being at least one process generation behind in fabrication technology.
Linked lists are just traditionally implemented linked lists. Hash tables are just traditionally implemented hash tables
Linked lists suck for caches, but hash tables don't have to. There's a trend for libraries to provide things like hopscotch hash tables as the default hash table implementation and these are very much cache aware. The real problem is the trend towards languages that favour composition by reference rather than by inclusion, which means that you do a lot of pointer chasing, which is very bad for both caches and modern pipelines.
The city council had spent millions remodelling the city centre to allow larger bendy busses when I was there. I never saw one more than 50% full and apparently a year or two ago they discontinued them. If they'd spent the same amount of money on more frequent, subsidised, minibuses, treating it as infrastructure that encourages people to do things that raise tax revenue rather than as a profit centre, then they'd have had far more people using public transport. Instead, privately owned bus companies have made a lot of money and it's now at a point where it's cheaper to drive than to take the bus.
Every week I drive to the supermarket and pick up 20-30 kg of stuff[*].
Why do you do this? I haven't done a big supermarket shop in person for over 10 years. It takes 10-20 minutes to drive each way, an hour wandering around the shop, I have to queue for the checkouts, and it's just a horrible experience. All of the major supermarket chains deliver and it takes about 10-20 minutes to do the shop online (5 minutes for a routine shop where I'm just adding stuff from my favourites) and then it's delivered to my door, by a van that's delivering to a dozen other people on the way.
I'm doing pretty well just to walk through the store and COLLECT the stuff. And no, nobody will deliver it, even if I had two pennies to rub together to pay them with.
Delivery from most supermarkets here is free and even from the rest it's far cheaper than the cost of driving there, even if you don't factor in the cost of your time.
