The energy expended to maintain a low enough entropy environment to do real work grows exponentially.
That is the biggest nonsense on/. since days, if not weeks.
Are you unfamiliar with thermodynamics? A fridge gets to be cold on the inside by increasing entropy more on the outside than it reduces it on the inside. That's the heat coming off the back.
If you made it colder on the inside you would be sucking more power and emitting more heat on the outside.
If you want to entangle 10 qbits, it needs to be colder than it would be to entangle 5.
You can figure the rest from there.
Go look at the IBM's website showing the inside of the lab. It's a tiny chip and lab full of cooling.
>destroying every advancement we've ever made in encryption by doing all of this
No. Just RSA and DH. Key sizes may need to double on some other algorithms. Quantum resistant public key systems exist E.G. NTRU. Ones that don't suck are a pipe dream right now.
Each time the add a qbit, the power needs of the refrigeration doubles.
This is why quantum computers can't beat classical computers. The energy expended to maintain a low enough entropy environment to do real work grows exponentially.
I assume it is LEAN software development, or dysfunction in the morning SUM, or one of the other pox ridden processes. In general I blame modern software practices that eschew sitting down and thinking hard before writing important code.
If I was in a position to want to keep my iPhone contents secure in that scenario (E.G. I was a drug dealer, journalist or both) I would want a kill code too. Use a specific finger, wipe the device keys. Use a specific code, wipe the device keys.
The NSA put a lot of effort into undermining open security standards, having people turn up and propose things that make it more complex, leading to inevitable security holes. I've worked in standards and seen it in action myself, with individuals who never deviate from proposing things that work against simplicity or ease of implementation, or sound algorithm choices "But what about all the legacy devices that only support RC4? Here's take this cipher suite negotiation mechanism that's guaranteed to ensure these algorithms never go away". It's not like it stopped after Snowden. I can point to events in the last 6 months. For all I know every other intelligence agency is doing the same thing.
So that's one reason why it's so complicated. There are other reasons but that's not my area of expertise.
Having had a couple of chromebooks in the house over the past few years, it became painfully apparent that the UI was going to some lengths to try and pretend that there wasn't a file system. This is what made them useless for me. Moving files between two devices became a process of sending them via Google.
My MBP doesn't do that to me. My PC doesn't do that to me. My work laptop doesn't do that to me. My phone does do that to me but it's easy to work around.
There's some difference in caching and virtualization support, the latter of which I really think needs to become a client PC product anyway. Running a HW virtualized OS under linux is very useful for gaming, but right now both nvidia and Intel like to think of HW virtualization as a server feature and charge a bunch of money. But given that Windows is no longer the obvious operating system for either every day use or developer use, HW virtualization is a lot more important.
My Broadwell NUC has virtualization support. Hardly a server CPU. Yes server SKUs all do the virtualization whereas not all the desktop and low power CPUs do, but if that's what you want, you can get it in a desktop CPU. For me it's great for SW development.
As a tech employer that recruited a 19 new techs for a new cloudstack operation in our business I can say that the millenials are feckless, lazy and generally (not all) way less skilled and capable than they believe about themselves.
At the other end of the scale in the 50+ range I found that older people had a reluctance to learn new technologies and techniques even when they were far more appropriate for the task at hand. They are also much harder working than most millenials which was personally suprising to me.
In the end the average age of the team we settled with was 38. 2 of these were under 25yo, 3 were over 50yo, 5 were 40-50yo and the remaining 9 were 25-39yo.
Having a creative tension between new-tech and sticking with what works is good. If you organization is sound, the engineers can argue their side and come to understand the right path.
That's why I specified 12V DC for lighting circuits. They are supposed to be on separate circuits from plugs. So why not? They would make LED lighting much more sensible.
220-240V AC is much more practical for power delivery than 110V. Ring mains are more robust and safer. But I don't see the US getting over its stupid electrical standards any time soon.
Alone an LED is robust, but in my kitchen ceiling, 1/3rd of the LED light bulbs (3 of 9) have failed in 2 years.
You either got a bad batch, or you have really crappy mains power. I installed more than 80 bulbs throughout my house three years ago, and since then, only one has failed.
I think the mains is just fine, because I looked - one benefit of being an EE. Crappy components, crappy circuit design or something. They came from home depot. It doesn't matter. The reliability claims didn't hold up. LED light bulbs are only as reliable as the circuit that converts AC mains to LED voltage because that's the weak link.
These are the top ones that come to mind in 5 minutes if I actually gave it some thought I could probably come up with some good ones.
I have no evidence to back this up, but my assumption is that the sudden plethora of razor-by-mail companies selling at prices far below Gillette was the result of some related patent expiring. Otherwise, why now? They've been expensive for a long time.
Alone an LED is robust, but in my kitchen ceiling, 1/3rd of the LED light bulbs (3 of 9) have failed in 2 years. This is because while LEDs are robust, the ultra cheap, crappy switch mode voltage converter in the bulb base is not.
Wire the lighting circuits of homes with 12V DC and you could have robust LED light fixtures. The robustness claims of line level LED lightbulbs are fraudulent.

It doesn't need to be hardware accelerated. Just programmed directly.
Netflix has some stuff but it's full of crap that takes some wading through and there's limited access to current movies.
The Roku can use Netflix, but it can also use many other sources. The Roku is plenty good enough to replace cable TV.

Not to mention that goats will bare all the leaves they can reach from the trees.
Goats can be simulated very effectively in a computer too.

I have never made less that $50,000 per year in the 17 years I have lived in the USA. My pay is not about to go up on the basis of this change.
