It runs on a hot-swapable battery system. The specs say 8 hours at 100% usage and a week on standby for one battery which is pretty good since if you are carrying this into the field, you can afford to carry a few more fully charged batteries with you or just have a small generator.

An Intel E3845 has a TDP of 10W so assuming peak power is 1.5 x TDP, then this would draw 15W as 100% power usage. There are 22 of these devices so there is a total of 330W dedicated to just the CPUs. There is no GPU, SSDs take up very little power as well as RAM so we can assume that the whole thing is taking up no more than 400W at 100% usage. A Li-ion battery has an energy density of 110-160 Wh/kg so lets assume its 110 Wh/kg. To run this thing for 8 hours at 100% usage with 400W of hardware power usage, you would need a 29 kg ~ 64 lb Li-ion battery. Energy density of 160 Wh/kg would need a 20 kg ~ 44 lb battery.

Or get yourself a little 1000W generator and run the system for a week on 30 gallons of gasoline.

Keep one of those host machines at work and one at home setup as a thin client so you can carry your core back and forth to work. Slide it into a host machine, it starts up near instantly because of the SSD and then brings up your remote workspace or even use it as an actual workstation although not sure how quick an Atom is for that. At work, you wouldn't need your own computer so if your company does hotel desks, you have a lot less to carry around. The host machine could just be one of those monitors they show.

Its not too different than those laptops that hook up to an Android phone via USB and HDMI. The real power goes into your pocket and the extra hardware can stay where it is.

Each card has 2 PCIe x1 buses coming out so if you hade a host machine that had a PCIe slot, then you could run a modern GPU. Maybe even with SLI/Crossfire although I'm not sure if that's reliant on having more PCIe bandwidth. The only issue would be the degradation in bandwidth going to the card as you would be going from something like x16 (or x8 or or x4) down to x1.

If an update goes out that inadvertently breaks every Tesla, a patch can be quickly distributed without having to wait. Assume they don't have OTA update capabilities. How does a user get a new update? If they have to go to the dealership, this can be difficult as states do not allow for Tesla dealerships to exist so you would have to drive a long distance just for software update. Any bugs in the latest update will now require you to go back to get version X.X.1 for that simple patch. Instead, lets let the customers do the update themselves. How do you install the update? Using a USB flashdrive would be ideal, plug it in with the *proper filesystem* (NTFS? Can't use OSX. FAT16/32? Outdated. ExFAT? Pay up to Microsoft.) and make sure the update is placed in the correct spot in the drive (probably the root). All of these are probably easy for slashdot users but not every Tesla owner is as tech savvy. The update process is even more important, removing the drive during the update could screw everything up, causing warranty issues (pay out of pocket because *you* screwed up).

For the ease of install, an OTA is the easiest solution. A broken car can still update as long as it can get a signal, the dumbest users have to do nothing, and you don't require your users to have to swing by the dealership that may be in the next state. The system also facilitates getting use metric data from the cars, something that can be incredibly helpful when looking at ways to increase the efficiency of the motors/batteries.

You drive a car because flying everywhere is expensive and not possible in most cases. You can't fly to the grocery store, to work, to school, etc. This isn't a very good argument. A better analogy is that you trust yourself to do car work better than you trust a mechanic. They are the expert and cost more to do the work but you have to read up on how to fix things and spend your time doing the work yourself. The expert costs money, you cost time (which is also money). Now your engine needs fixing. Do you pay for someone to figure it out for you or do you try to do it yourself? Both choices might have disastrous results; you might fuck something up big time and have to spend way more time fixing your mistakes, the mechanic might not get things done on time or within the estimate he gave you. Hell, in both cases, you might have your car stereo stolen either right from your driveway (a targeted attack) or from the mechanic's parking lot (an attacker looking for the easiest thing to steal). You might have a motion light pointing at your driveway and yard but its just you at your house guarding your stereo, maybe you spot the guy because he just walks right up to the house and the light goes off. The mechanic might have a fenced-in parking lot with a rent-a-cop doing their nightly drive-bys at various businesses, maybe he spots the guy trying to get past the fence but failing.

It's all a matter of money and time. What do you have the most of?

Just because the government purchased something doesn't entitle you to its use. You don't get to borrow a navy fighter jet because your taxes helped pay for that. Besides, that $9.1mil is probably based on a certain number of licenses, it doesn't cover you.

Microsoft is probably better off just sticking to what they do well, the surface and its derivatives. Their phones have always been less desirable and they can never seem to come out with a product that people actually enjoy using. They do well with their tablets and should stick to keeping those up-to-date with the latest tech.

Comment Re:the 360 had HDDs in a custom candy with bans wh (Score 1) 98

There were definitely no bans from swapping out HDDs in the 360, it just wouldn't allow you to format and set it up for use. The only issue was that it would only recognize a certain set of OEM firmwares. You would have to buy a comparable drive made by the same manufacturer (WD, I recall), flash it with the right firmware, and place it in the drive caddy. This would then match up with the Microsoft branded retail drives available for half the price. When they switched to the 360 Slim, you were able to use any SATA 2.5" drive you wanted. You didn't even have to use the plastic caddy that the retail ones were sold with. A folded up piece of paper worked nicely as a spacer to keep it from moving.

The xbone has USB3.0 support so adding a new internal drive isn't even worth doing anymore. Just get a cheap 3.0 enclosure and whatever OEM drive you'd like.

Because you aren't paying for it. Should Redhat give you free support when other companies are paying for the creation of documentation? Should a Amazon give out all their ebooks for free because someone already bought a copy of one of them? I mean, its already paid for so just give it out for free, right? It's not like these are businesses that rely on paying customers to run or anything stupid like that.

Plus, MS wants to move away from XP. It takes away from their talent pool to work on a 15 year old operating system that very few people actually want to run. Software engineers are wasting not only their hours but their potential working on XP. MS would rather have them work on new things than work on old things and the engineers would rather be coming up with new ideas rather than just patching old mistakes. Anyone looking for stability for current hardware can install 7 no problem so your average business/consumer has no specific need for XP anymore. If they are going to keep patching it, they are going to want a bunch of money to compensate for the time and money sink that it is.
