But Uber was the first one with an app as far as I'm aware.
They were one of the earlier ones, but by no means the first. Uber was the first however to have an almost unlimited stream of VC money and a willingness to simply break the law until it won.
It's not just about pointers. The CPU processes *everything* n-bits at a time, with n-bit precision.
No, it's only about pointers. Desktop CPUs go up to 512 bit wide instructions with the latest AVX. And they're super scalar so they are 256 bits or more wide, but they use that width to do several operations not just one really big one. There's not much utility in 128 bit arithmetic so they don't waste the silicon on it.
Bus bandwidth was a problem and a 128-bit bus seemed likely in the future.
We went flying past that.
The internal memory busses are based on cache lines which are also 512 bits wide in big CPUs: that's how much memory it fetches in one go.
DDR 4 gives a 64 bit width, but processors now support quad channel DDR4, which gives an effective width of 256 bits to main memory.
Microsoft ditching Internet Explorer for an open source web browser. Miracles and wonders abound!
Not only is it unexpected, it's also probably for the worse, which is an even more unexpected thing. The web was not good as an IE monoculture and it's moving dangerously close to a chromium monoculture.
About the only reason google isn't now as bad as microsoft is because thye can't seem to keep one idea in their collective head for more than about 5 minutes before deprecating it.
Nintendo 64 came out more than 20 years ago, so kids owned 64 bit processors. The surprise is that although we went from 8 bit to 64 bit in 25 years, after another 25 years we're still on 64 bit.
Why is that surprising? That corresponds to 16 exibytes (well 8 if you have signed pointers). There's no machine on the planet which could make use of pointers of that size. And if you happened to have exabytes of storage, well, the latency would be so high that doing a 128 bit integer as 2 64 bit add-with-carry's is not going to affect your speed even slightly.
There's just no need for pointers larger than 64 bits now and there won't be for a while yet. There just aren't enough applications where 128+ bit additions are the limitation, such that it's worthwhile implementing the hardware.
Internally processors are much wider than 64 bits.
We called it a VCR. I also probably still have a PCI video capture card in my storage room. Maybe even an ISA one. Cards like those were popular with Windows Media Center, a DVR that with Windows 15 years ago. 20 years ago, the DVR was a separate application that didn't come with Windows. *Renting* a DVR instead of owning it is new.
I've lost mine. I had a few BT878 based ones, discards from windows users because they could never get them to work. Thr drivers on Windows were absolutely awful probably because it was a little niche and everyone implemented their own crappy drivers from the datasheet. On Linux they were absolutely rock solid in the early 2000s, probably because they all shared the same driver and it got much more work on it.
And no one there might go to a better company ever?
Yes, and? A reasonable attitude in hindsight was "wow that was a shitty company why the hell did'd I give my 2 weeks notice ans quit (or fuck right off like the other guy)".
If someone's holding a grudge 5 years out over that then be thankful you're not working with them again.
F-22 has engines that provide so much efficient thrust, it can cruise at supersonic speeds without using the afterburner.
So did the concorde.
It didn't need afterburners to accelerate Mach 1, it was simply more efficient to do so. The concorde cruised at Mach 2.2 without afterburners running, which is somewhat faster than the F-22 can supercruise.
. Oh please, grow up. If you want to be treated professionally, then be professional. If you don't get treated professionally, move on when the time is right, be professional, and never look back. Positive change doesn't come from acting first and playing tit for tat. It comes from doing what you know is right even when you might not expect to see a return. What benefit does just walking out possibly have? Yeah, you might feel cool for a day or two, but you've burnt a bridge.
That all works both ways. Now, I can't see myself ever doing this but...
Some companies are shitty. If they've already burned the bridge with you, flipping another match at is isn't going to make it any more burned.
If EVERY prof said "Cut this shit out or we resign" the university / colleagues would change their tune.
Profs gotta eat too. If you have no social safety net that allows for that sort of ethical action then this is exactly the sort of thing that can happen. Being able to eat and make rent is almost always going to come top.
And when you say "every" you're not far off. Academia is hugely competitive with people devoting their life for the chance for a job when there's 10 times as many people as there are jobs.
Even if only half of them did that it would not take the universities long to refill.
Europe is an entire continent, the US and China are countries.
This is arguable the most vapid thing on the thread and that includes that binary chap bragging incessantly about his ignorance.
China has twice the land area and 3 times the poplation of Europe. The fact that one is a continent and the other is a country is kind of immaterial.
And the US and Europe are very comparable. Similar population (Europe a bit larger), similar GDP (the US a bit larger), same level of industrialisation and so on and so forth. Both are essentially trading units, with the EEA being the largest trading bloc (by a bit).
Eurpoe and particularly the EU (or EEA) and US are very comparable.
Are there still people here who believe in this "long tailpipe" nonsense?
Even if they do, it's *still* a stupid point. I mean if you have the choice between spewing out pollutants exactly where people live or a long tail pipe, the latter is vastly preferable. Having long tailpipes in city centers is a very good idea and arguably more important than CO2 savings.
You can easily spin off threads that cause all kinds of subtle bugs that pop up rarely - infrequently enough that you're unlikely to catch them in tests, but often enough to cause problems for customers or even lock up the entire occasionally.
I think a good rule of thumv is that if you see some sort of general purpose class (i.e. not something like a message queue) with a mutex or atomic in it, you've seen a bug even if you don't know where it is yet.
It would be great if we could cause rapid warming in these two states.
Yep they are an oaffront to reality what with being all liberal and regulation heavy yet also being commercial powerhouses. The solution to reality defing people is to destroy them.
FFS if you don't like California or New York don't go and live there. There are plenty of states to choose from which they susidise.
Whenever I see this, I know the conclusions are bollocks.
The only way to know something which is demonstrably false is to be an idiot.
The original IPCC report had climate models in it. The climate agreed with the future predictions to within the error bars, demonstrating the models were not in fact bollocks.
Now, please start my inevitable downvoting.
Yes if you post something that stupid it will get downmodded.
OTOH, Go's several different ways of handling concurrency are much easier to grok and "get stuff done".
Well yes. But that's the problem. It's easier to hack stuff out in go because when it comes to threading it doesn't do much to stop you shooting yourself in the foot. Pretty much the entire reason for the existence of Rust was to enable the moz devs to write fine grained multithreaded code without creating a nest of subtle threading bugs.
The reason it looks harder in Rust is because writing correct multithreaded code is in fact hard. Annoyingly so.
If not, I can just see the "to collect and serve" police guys out there catching people washing their mandated solar panels.
Not trying to be funny, I'm serious.
I am sure you are. It's something that seems to go on a lot with wing-nuts here. Invent a wild scenario then get angry about it. You demnostrate your wingnuttery by doing that.
The rest of the nation thanks you for kicking yourselves pointlessly in the nuts so you can water a desert so we can have winter vegetables and avocados.
The rest of the nation seems to thank California by paying it lots of money. that's why it's rich and lots of people want to live there.
Whether it's popular despite or because of the regulation is left as an exercise in political dick waving.
The applicable provisions in that law were struck down by the Supreme Court for violating the free speech of non-medical clinics and putting an undue burden on medical clinics.
Well that's inane for different reasons.
I don't see why people should be able to get free speech while under limited liability protection. Anyone should be able to speak freely as a private citizen.
Here we are a century and change later. People are apparently still confused about efficiency and economies of scale. Apparently way too hard to grasp increased efficiency and less environmental impact is achieved when done at scale rather than thru piecemeal generation.
The solar panels and voltage conversion gear is all going to be manufactured at massive scale. And it's all with the same tech.
Thermal plants are definitely better at scale. High thermal gradients lead to inefficiencies. And it's more or less impossible to make a worthwhile small LP turbine, but they're needed to squeeze out the last 10% of efficiency. But for solar, factories churn out panel after panel after panel. They're the same whether they wind up on a house or a commercial installation.
Economies of scale certainly do work, for installation, but these are for new builds, where you've already got builders and electricians on site.
Then there's the reduced load on the grid and reduced transmission losses.
It's all a tradeoff. You have no hard numbers to back up your claim.
WHAT is the efficiency of a commercial solar plant vs home plant?
Worker protections? You mean the deplorables? We hate them, remember?
Another example of how you hate the right. When Hillary was talking about the deplorables, we both know she was talking about the alt right. What I want to know is why you keep smearing the entire right wing with the same brush.
For someone who identifies as right wing you sure seem to despise them. It's weird. Maybe that's why you're so angry.

Yes, with the latest AVX. AVX didn't exist 20 years ago. I'm talking about what we expected 20 years ago.
OK... but we had 128 bit SSE 19 years ago. Close enough to 20. And they were already superscalar by then.
It seemed entirely logical that we'd go from 64 to 128. Instead, things went in different directions.
It really didn't. Pointers and integer primitives stopped at 64 bits. CPUs keep getting wider.
It's not just about pointers. The CPU processes *everything* n-bits at a time, with n-bit precision.
No, it's only about pointers. Desktop CPUs go up to 512 bit wide instructions with the latest AVX.

When you add a thread, you add a bug.
No arguing there.
I've definitely seen code where the author clearly believed that sprinkling "atomic" around like magic pixie dust makes the code thread safe.
