Recent security lessons
Aren't we now running processors that have had to be hobbled because of the resources they intimately share? Are the people who paid extra for hyperthreading and similar still getting the benchmarks they paid for?

I gave you a thumbs up because you're making people think and raising quality standards by playing devil's advocate.
If a lawyer defends a well-known criminal, the lawyer may strongly suspect that his/her client is guilty, but it would be in *everyone's* interest that the evidence be tested very carefully.
"The Planck constant, named after the physicist Max Planck, is incredibly small (it's 6.62607015 x 10-34 Js)"
I think we need to be careful about describing units as large or small, when the magnitude of the numerical parts of their value is a function of the units we've chosen to use.
For example, would it be reasonable to describe the speed of light as incredibly small because it's 9.71561e-9 parsecs per second?
If we deployed a large sunshade near Venus, large enough to put the whole planet into shadow, the planet would start to cool and begin absorbing CO2 by chemical weathering. After some millions years, maybe even Earth-like tectonics may begin. Teraforming Venus is definitely a long-term project.
Besides other things mentioned, I guess it would rule out the use of cryogenic propellants such as liquid oxygen. By the time, you got the rocket up to height, it'd be covered in ice and a lot of propellant would have boiled of
Also, recovering the rocket and payload if there was an aborted launch would be a problem.
I "guess" as you have put solar energy in you must get more energy from burning the carbon monoxide and hydrogen
I think the solar energy is effectively used to split water and the water is reformed at the end, releasing that extra energy. Doing that without the involvement of methane would be more difficult.
Most people are not technology-sensitive. What they care about is cost, and what they can do with their Internet connection. Most are therefore still oblivious to the fact that their fast Internet is perfectly capable of handling their telephone traffic at near-zero incremental cost, even for many international calls, just as their visits to web sites are.
So they continue to think that they need something separate, and continue to be charged in the old way. I am not asking for FTTP to be universally installed. I am asking for more FTTC (which suffices for telephony). I do not want Ofcom to ask, as you do, what evidence there is that people are wising up to the new possibilities. When it comes to improving our national telecoms, they should be proactive, acting for the general good.
Ripping up the old copper wires to the exchanges would be a one-time cost that will have to be done eventually anyway. The sooner it's taken out, the sooner the ongoing maintenance costs end. This should be part of the process of rolling out FTTC to a neighbourhood.
No problem. Just get your land line discontinued. I'm sure your ISP will find some other way of connecting you
In the UK most consumers who need a wired service are forced to use either a service that uses Openreach or Virgin Cable. With the former, you're required to pay for an ordinary phone line too. Virgin therefore makes you pay for a phone line whether you have one or not. Indeed, you're often quoted more for service without a phone line.
These days, we should be plugging our telephone handsets into our routers. We're well passed the point where we need to replace the USO for phone service with a USO for broadband that includes VoIP.
None of the big telcos will put the old cash cow at risk by offering a VoIP service that competes with it. You have to go to a company that specialises in VoIP service. That is why we need a regulator to act.
I'm typing this on a 2010 mini with its original HDD. It's been running 24/7 since new. The only upgrade was to put 8GB of RAM in when new. I have long considered replacing the HDD with an SSD but have instead been waiting for a new mini because I also need more than two cores.
If my mini fails (likely to be the HDD) before a new mini is out, I will simply buy a new PC, transfer my existing Windows VM to that, and give up on running native Mac apps. I certainly won't spend a fortune on new Apple kit with a screen I have no use for.
My SH1 died and I asked to have a replacement sent to me. Not possible they said. Wait days for an engiineer to come, they said.
He installed a SH3. I later found that it can't support port forwarding rules and DMZ at the same time. With the "firewall" on, one works and the other doesn't, and vice versa.
Never heard of that, they said. Not possible to send you a different SH, they said. So I asked to refer them to the Vigin Media support forum. The effect was the same as if I'd used a Jedi mind trick. A SH2 arrived the next day.
I'm sure the individual staff members aren't inherently dishonest; more likely it's a bad management ethos that's filtering down to the support personnel.
In 2010 ( think), Sainsbury's were sending out marketing emails despite my account settings recording that I had opted out. Towards Xmas, they were sending emails most days using a third party spamming house. My complaints and instructions to delete my account information were not acted upon.
I considered getting heavy with them, but instead I set an email filter to forward all Sainbury's emails back to Sainsbury's, with the hope that they would automatically acknowledge receiving each one.
It wasn't until five years later that I found the filter was no longer needed, and they got another order from me. During that time, all my online grocery shopping went to rivals. Ultimately, that's the real cost of doing this sort of thing, not a token fine.
My next computer is likely to have an SSD, not an HDD. However, admittedly a few years ago now, I traded in one netbook with sold state memory whose performance quickly degraded to the point where it was hardly usable. That experience informed my comment.
One alternative technology that intrigues me is SONOS.
"Seagate has a 15K 2.5-inch Enterprise Performance drive, launched in October 2016, that also has 300GB, 600GB and 900GB capacities. It has three platters and six heads at the 900GB capacity level, which suggests Toshiba has an areal density advantage."
Maybe the photo is of the 600GB model.
"Don't forget it needs to be gold plated as well, you can really tell the difference when they are, honest!"
Especially valuable with optical connectors, of course. It's not just PC World offering such bargains. http://www.maplin.co.uk/p/maplin-digital-optical-mini-tos-adapter-a14ny .
Speaking of white elephants, they don't get much more expensive than the International Space Station. No chinese involvement in that, AFAIK. We could've had a huge number of interplanetary probes and landers for what that cost, and the cost is still rising because noone will cut the losses lest the prior waste be more obvious.
It's nice that my 2010 Mac mini is still running, but the main reason is that Apple still can't manage to offer a quad core replacement. When it fails (likely to be its hard drive), it will get immediately replaced by a PC, not a £1,200+ quad core iMac with a fixed landscape-oriented display. I'm not in the market for a computer that is expensive furniture first and computer second.
At least he can put this result on his C.V. to enhance his reputation. I suspect the organisers are not too keen on transparency in this case.
Now, if I felt inclined to be really cynical, I might wonder if he was awarded the result for the purpose of depriving someone who was eligible for the money.
"I think I was going for the decent selection of PCs in my hometown, you have no choice which is rather more correct."
By all means make your choice at the store, but make sure you buy online from someone else. The chances are the online equivalent has a higher spec, even if the main part of the model number is the same, or will at least be cheaper, even with delivery. If you get a dud (it happens) and have to return it, you likely won't get an argument from someone professionally obstructive.
I think a lot of installed HDD capacity is going unused, especially in domestic PCs and that will tend to increase as areal densities increase. Manufacturers of PCs know that if they have a choice of fitting a 1TB HDD or a 500GB SSD at the same price, the 2x price premium of SSDs is not sufficient to choose a HDD.
HDD manufacturers could offer crippled drives at a lower price, but that won't change the manufacturing cost. One option might be to shift to making a lot of drives smaller than 2.5" .
