Make an image with two layers. Set one to 50% transparency and put it top. Now try to move one on top of the other and resize it to line up a few points in the images. I for example was trying to line up the wheels in two car silhouettes.
In the GIMP, the layer you made 50% transparent turns opaque while you try to resize it, so you can't see how to line up the layers. What a mess.
I went home later and did it in Photoshop CS3 (that own, but only at home) and it worked fine, remained transparent during resize.
I know it's free and all, but if you make your living doing image editing, the GIMP is absolutely no substitute for Photoshop. You'll easily waste more money in labor than you saved not by buying Photoshop.
First thing: omitting other things besides Federal income taxes because it's convenient. As if not paying Federal income taxes means you don't pay any taxes. As a teabagger you know better, you're leaving it out to mislead. Second thing: these people only pay 0 taxes at current rates. Increases in spending doesn't automatically mean increases in tax rates, you could argue that EVERY PERSON is in the situation where increases in spending don't cost them anything. It isn't true of course, because taxation would have to increase over time to match the spending, but people who pay no Federal income taxes currently are not immune to increases that might make them pay either, once you exceed that exemption you start paying!
As much as tebaggers would like to say it is so, the poor (those who pay no taxes, disregarding the rich who have nice tax loopholes) don't really have the power in this country.
That's because you had your email set to poll. This is push, where phone is contacted to indicate something happened instead of it checking every 5 mins.
Trojans work because of faults in the human operator, not because of faults in the OS.
It's not a Mac fault, and to carry your allegory forward, it'd be like if car companies recalled cars because it was possible to get in a wreck if you drive them into a wall.
Seriously, I'd mod you down if I hadn't already posted in here.
Stop with the pariah attitude. If you post tangentially related (at best) stuff about how you don't like Apple repeatedly, you'll get modded down, period. Add something to the discussion besides (hey, did you know Apple is still censoring apps!) and you might be treated differently.
Just because you want to say it a lot doesn't mean people want to hear it everywhere.
The iPad (even non-3G) and the Touch also have the ability to stay logged into a WiFi network in very low power mode and so can get push data over WiFi. And I can't imagine these were forced by AT&T.
Besides, what if you are in an AT&T dead zone (of course we all know these are mythical;) and you get a FaceTime(TM) call or try to Find My iPhone? Wouldn't you like it to get through on WiFi even though you can't get a push over 3G to your phone?
BIOS only supports booting off a 2TB hard drive, an x86 processor in 8086 Real Mode and you have to have text display (BIOS INTs) working in case the code puts up a menu. Heck you'd better have VGA compatibility working in case it wants to draw graphics too!
This is a lot of limitations. It means no other processors (ARMs?). No booting in 64 or 32 bit natively. No booting off the net. And soon even hard drives will be too big for its ken.
Any capabilities beyond this are hacks and thus aren't standardized or even necessarily functional.
I know EFI is overdesigned for what it needs to offer. But it does work, and we need what it offers.
My next motherboard will have EFI. It better have backwards compatibility support too though.
Having done a little work with this, I think kernels are written in C because of issues with the runtime library. The C++ runtime is more complex to get up and working, and a kernel needs a different runtime library than the rest of the system because it has a different memory map and it doesn't make syscalls to the kernel to make things happen at the back.
Also, in the kernel there are plenty of places where you don't want anything happening between point A and point B that allocate memory or touch user space or manipulate semaphores or whatever, because you're in a critical section. Well, part of the whole design of C++ is a single statement can turn into dozens or hundreds, and often these statements will auto-allocate (and de-allocate) memory for you or use other resources. So you'd have to be real careful if you used C++, so careful that I'm not sure you get much from C++ except namespaces.
So in short, I think the reasons kernels don't use C++ cannot be directly applied to a compiler. It has its own reasons (primarily bootstrapping) though.
Also, kernels don't use much assembly, I'd say "lots of assembly spices" is an exaggeration. You can never get the amount of assembly down to 0, but neither do you use it that much.
I have no idea where you get your idea that it's only on 10% of computer systems. It's on every Mac and Windows 7 machine for starters. And that's over 10% of the market. And anyone who has VLC or Windows Media Player on other platforms.
And support for it is near ubiquitous in HD video players. Portable ones, etc. That's a big market. As I mentioned, it's in cable (and free to air) systems in Europe, it's on all DirecTV boxes that do HDTV (and many that don't). It's in virtually all HD camcorders.
H.264 is massively entrenched. Which content do you think you're going to get in VP8? DirecTV already adopted H.264. Cable is stuck on MPEG-2 at the moment, but will definitely take whichever format allows them to use their limited bandwidth most efficiently (H.264). What about cable in Europe, DVB? Nope, that already went to H.264. Will pirates give up a little bandwidth to use a free CODEC? They're already pirating content, you think they care about licensing fees for CODECs? Blu-ray? H.264 (and VC-1). CD-DVD? AVS.
The bizarre part to me is that you got modded up for your comment. Who thought this comment added to the conversation?
I think VP8 will get some use, but victory over H.264 is extremely unlikely. It's just too little, too late to take the lead.
Especially when we are talking about Rockstar here. Remember GTA IV? Remember how all the sites competed to give it 100's more rapidly than the other sites? And remember how it wasn't nearly as good as the reviews said?
I'd rather wait for a review that is more thought out and comprehensive than read reviews that just rush to gush.
They can copy your car key. They can clone your garage door opener. And they have your address from your NAV system.
They could perform a home invasion on you, which is at least as bad as being carjacked.
And you're going to identify them? In order to do that you'd have to see them again, which isn't possible if the person just showed up to rip you off and was only impersonating a valet.
You can identify one type of unlikely situation where you can get in trouble but ignore another. Another which is more likely (although realistically both are unlikely).
You need to be able to use larger than 32-bit block addresses. This is possible since the LBA spec uses 48-bit addresses. But the internals of some OSes use only 32-bit block addresses. The solution to this is to use a 64-bit OS. That allows 48-bit addresses (and then some).
Another other problem is that the MBR disk partitioning scheme uses 32-bit block addresses, so you can't partition a disk larger than 2TB. But the answer to this is to use GUID disk partitioning.
Finally there's your BIOS, it probably only supports MBR and 32-bit LBA. GUID disk partitioning supports making your disk look like an MBR disk so you can boot off it. You'll have to boot off a partition that starts within the first 2TB of the disk, but other than that you should be okay. Just make sure to never use any tools that think your disk is an MBR disk when you are repartitioning it or otherwise accessing it directly.
Windows 7 (or Vista) 64-bit supports >32-bit LBA and GUID disk partitioning.
And then finally hope you don't get any nasty viruses that try to go around the OS to access the disk (so as not to be detected) and mess it up when the calculations overflow 32 bits.
It's bad OnStar exists. But then when they won't want to give it to you for free, that's even worse!
Things do cost money you know? If you think you shouldn't have to pay for the monitoring separately, then lobby your government to take it over. You'll still pay for it, but then you won't have to worry about it being taken away.
I dunno about OnStar being hackable and neither do you. I'm sure you could socially engineer it. Valet has its risks too, they can steal your car or even copy your key and come steal it later. They can dupe your garage door opener button so they can do a home invasion!
You're getting excited over a lot of nothing.
I agree the ads are scaremongering. Unfortunately this is common with car companies. Check out the Subaru "my Subaru saved my life" ad that airs right now.
The math of the transmission (which is just a differential/epicyclic) says otherwise. Any load on the output shaft is directly transmitted to the control shaft. Basically, you can't just make energy disappear in the system. If the engine is producing it and it isn't going to the output shaft, then it's going to the control shaft.
See the planetary setup on page 10 with an engine (power input) on one side and an electric motor on the other "input" and the output comes out the side (ring gear).
The power from the engine (carrier) is split between the generator (sun) and the motor/output (ring gear) and this ratio is continuously variable.
Toyota's system is slightly different in that the motor is at the output shaft, there is no control over the "third shaft", but the motor could easily have been put there instead.
The motor is on the "third shaft". Your steering input is at a fixed rate (let's say) and by BMW turning their DC motor (third shaft) of the planetary set, it alters the output shaft speed. If they turn it the same way you are turning, it adds to the output, it makes the steering quicker, if they spin it the other way it slows it (but increases torque).
Frankly, I'm sure there are more examples outside cars.
Immersion cooling makes sense from a lot of perspectives. However, there is one enormous problem. That is that chips aren't rated to work when immersed. You will have to get the companies who make the chips to specify that the packages the chips are in will are designed and safe to use in liquid. And they're going to charge you a lot of money for that. Frankly, it'll make the device non-cost effective.
You can just omit this step, and throw something together with air-rated chips and hope it works anyway. But you don't really want to depend on such a system for mission critical services.
If you want to buy a clone card, that's one thing. But if you decide you'd rather pay full price for the real thing, you shouldn't end up with a clone pretending to be the real thing.

Take a look at page 10 and 11 of this link. It's the Hybrid Synergy drive "power split device".
http://www.toyota.co.jp/en/tech/environment/ths2/SpecialReports_12.pdf

In the world of hardware there is an enormous difference between the two. You can easily have $1M in revenue and lose your shirt (make a huge loss).
