And here I just thought it would be slow as molasses because it's running on a "plug computer" with a marginal amount of memory. Just because ones duty cycle is only 5% doesn't mean you actually want to get by with only 5% the computer.
I don't know what it will take to get people straight on this. WebM is a standard, it just isn't standard. It is a static, published set of audio and video codecs, and a container to package them in. It is just not standard as it has limited browser support, and no hardware support.
Some back of the napkin calculations, in order for a 2m tall person to have only 1% difference from head to toe, you're looking at a 200m radius and rotating at 2rpm. Worst case, that's about 45m/s if the tether broke. That's not sufficient to deorbit immediately unless you're already extremely low, and could easily be replaced by an emergency booster.
As for the counterweight, the best option would likely be to keep your last stage rather than discarding it into the atmosphere. You're going to have it with you anyway, may as well use it rather than try to capture old satellites that happen to be in the same exact orbital inclination and past their lifetime.
Yes, because the non-inflatable spacecraft would fare so much better when they get punctured... When both options have the same fatal consequences, you can't use it as an argument for either.
It depends entirely on the use scenario. Consider someone loads up a video game, and loads several files from a given folder. If the cache is aware of the filesystem, it will precache other content from that same folder, such as additional models, maps, and textures. When the game then wants to retrieve those files, they are ready to access, rather than having to pull them off the disk.
It has nothing to do with Windows trusting the key, and everything to do with the hardware trusting the key. If GNU gets their own key, then by principle, everyone will have that same key. If the hardware lets everyone in, they it also lets in people trying to install rootkits and other malware at a low level.
The idea of this mechanism is that it would act the same as UAC. The user is still free to do whatever they want with their hardware, but installing bootloaders, operating systems, drivers, or anything else that interfaces with the hardware directly will require signing with keys matching those stored by the BIOS. If the user wants to run alternative code, they have to drop into the BIOS and add that key. If the user wants to run unsigned code, they have to drop to the BIOS and disable it completely. It's just supposed to be one extra step to make the user think about what they're doing, and whether or not it's actually a good thing to be doing.
The problem, as always, is not how something is intended or advertised to be used, but how it can be abused. If hardware manufacturers decide to not give the customer access to the BIOS to insert their own keys, then the system becomes a partially locked platform. Worse still, if the system allows software to be re-keyed, OEMs could start distributing their own copy of Windows that can only be run on their line of computers, and is the only software their line of computers can run. There will be no installing other operating systems, no upgrading to a better copy of Windows, no installing a vanilla retail copy to flush out all their pre-installed crapware. Whatever the manufacturer decides to do, you are at their mercy.
On the opposite side of the argument, should any of these keys ever be compromised, all hardware that allow those keys are now open for attack. It's the same basic problem with DRM, why it can never be completely secure. It's the same concern people have with the public key certification infrastructure, that has come true with the recent breaches in certain certification authorities
But the fancy graphical interface IS a new one, and you only have access to the fancy new graphical BIOS configuration utility. If it were the age old BIOS configuration utility, you would have no problem pumping that over a telnet or SSH terminal. It's not like you have meaningful access to the OS installed on the system such that you could tinker with the system or replace drivers.
Except this is new, and retarded. A full IP-KVM solution makes sense. It allows you to actually connect to and use the PC remotely without any additional software needed. That is not what this is. This is taking the graphical UEFI configuration utility, rendering it, compressing it, and sending that over VNC. You can only access the configuration utility, and not the local terminal. Rather than use a sensible mechanism of remote configuration, like an SSH or web application, they chose VNC.
Agreed. VNC just seems like a stupid choice for such a system. VNC, Citrix, Windows Terminal Services, Remote Desktop... all of these things only exist as a crutch to allow remote use of programs not designed for remote operation. If you are designing the application from scratch, why not design it for remote use in the first place? Use a terminal or curses application. Use an embedded web server and a javascript application. Do something that actually makes sense rather than render a 2D interface, and then compress it for display over VNC.
Yes, a real address through a real mail server, rather than one that just accepts anything and everything, even if it's just going to be immediately discarded after the authentication process. Users can manually do it. Bots can do it too, but blocking mailinator and their ilk means I block out a big chunk of the spam that is pointed at the wiki, and spend less time cleaning it out the accounts that still do end up getting made. There's never any perfect solution, but blocking them put an end to what was several new users every day generating spam.
Looks like I need to retract that one. None of the handful of users signed up through spamgourmet have been banned due to spam, of course none of them have made more than a single minor edit either. The real culprits are things like mailinator or mytrashmail, and I had added spamgourmet to the list after skimming the list of email domains and assuming them to be set up the same.
I've started proactively blocking mailinator.com, and any other domain I find that forwards their MX to them, on a wiki I administer. For every one legitimate user signing up, I have fifty more who are just generating spam accounts. Considering one sixth of all users ever make a single edit, and one twentieth make five or more, anyone who's going to stick around and become a meaningful contributor is likely to be willing to give a real address.
Even if you don't damage the cables, if you pull them too tight, there's no way to cut them off without cutting through one or more of the cables in the bundle.
I strip open unused solid core CAT6. You're certainly to have plenty free. A 10' section costs about a buck. Five minutes with a box cutter and electric drill to unwind and you've got 80' worth.
So it's not as though all those weed sales will transfer to cocaine or heroin if marijuana is legalized. They'll simply go out of business, or become legitimate, like beer producers did. Beer producers didn't say, "Shit, we can't dodge taxes and shoot at the federal lawmen anymore... so screw beer, we're going to start selling heroin!"
No, they went legit, and the guns went away. The gangs and mafias changed to do other illegal things, but they lost a huge portion of income. The same would happen with marijuana.
Does that mean all the former drug runners would start start up a boat racing circuit?
Plus if you're using passive induction on one side, it only works if you're moving. 'Boarders' would have to be a brisk walk or jog just to get enough lift to ride the thing.
That's fantastic and all, but you're completely missing the point. The fact that it was powered by a PV cell is irrelevant. What they are showing off is a Pentium core and DDR3 memory idling at 10mW. They are showing off a processor that has a hundred fold or more difference between idle and load. You no longer shut off your PC, you no longer put it in standby, you just let it go into low power mode indefinitely. The PV cell was just a demonstration of how low power it was.
Actually, they are talking about one system. It's a custom server designed for GPU computing, and has 8 PCIe 2.0 x16 slots filling nearly the whole back side of the chassis. They're using 8 32-core cards to render the images and video.
Why would schedule updates be sent individually over the internet, rather than simply broadcast to everyone on a spare channel? That just sounds like a hideously inefficient use of spectrum.

The bubbles mean it's working!
They have been doing a lot of cloning research recently.

It will once you realize you can't install what you want on the machine.
A fraction of the speed, and only one core, they should have codenamed it Clark.

Sadly, these disposable addresses are used far more by spambots than by legitimate users attempting to avoid spam.

What about the cords to the monitors on the left and right of it?
