Let me be more specific. A c-style language that isn't type-safe can be a royal pain in the ass to debug if you don't know what to look for. While compilers can often give "cryptic error messages," students aren't going to have too much more fun when their scripts aren't working. Maybe the fun/power of the browser will make up for some of it and keep people interested. And these days, learning the structure of the web is fairly important and fundamental. Still, it sounds more like an "introduction to web programming" than cs 101.
Also, rolling into someone at a red light because you were distracted is a lot different than rolling your car on the freeway. They're both accidents.. but which do we really care about? I'm pretty sure people are more likely to text at a red light than in heavy traffic at 75 mph.. An increase in fender benders doesn't worry me a whole lot. An increase in those collision avoidance radar systems will clear that right up...
Well, it might be useful if well engineered. Take intel's 320 line of SSDs as an example. They have full-drive hardware encryption. You enter a passkey when you turn on the machine to unlock the hard drive. That key is used to decrypt the actual key the data is encrypted with. That lets you change the key without reencrypting the entire drive. While it wouldn't be practical to have the entire disk self-destruct, you could engineer a single chip which would. Then the highly complex key is permanently destroyed, even if the suspect is forced to give up the key. So if you're arrested, they'd only have say a 72 hour period to force you to release the key. It's doubtful they could manage that. And hey, maybe an expired key responds the same way as an incorrect key. They'd have no way of knowing if you'd ever provided them with the correct key. As long as they don't know what the timeout window is before it's erased, you could give them a garbage key after 12 hours and you'd still be safe from incrimination..
Some good info. I wasn't recommending c++ though. I was recommending c# or java. The IDEs will break on a thrown exception in user code. You'll see pretty well exactly where you screwed and what you're not allowed to do.
Well, a segfault and a line number vs. the IDE jumping to the line, highlighting it, and telling you something like "cannot divide by zero" with the entire callstack and locals so you can see exactly where that input came from.. Or say a file stream is only open for reading so you can't write to it, etc. Let me give you an example from school. I can think of one frustrating time where I spent a good 8 hours trying to fix bugs and leaks in a kernel I was writing. I was implementing multitasking. So you have to swap in/out the memory perfectly for it to work. You make a mistake in one place and it blows up somewhere else, or crashes on exit. It's miserable. I was trying to recommend the environment which provides enough help that a new user won't feel stuck. They'll be able to google any exception text and find an explanation. That's pretty useful compared to a segfault and line number, especially for more obscure problems.
As far as exception handling being too much abstraction. If you don't know about it, you really won't worry a lot about it. It'll just be information you get for free when something bad happens. To me, that seems like a good trade-off for a newbie.
You can do that with many compiled languages as well. That's what the "immediate window" in visual studio is for. It's available when you hit a break point (and have some context to run the commands in). So in c#, if there's a method I want to poke around in and 'explore,' I'll set a break point and poke around the watch and issue some experimental commands from the immediate window.
I'd recommend a compiled language with exception handling. I feel that makes it a little harder to get stuck/frustrated without any clues. The compiler keeps syntax in check. Exception handling gives a better clue as to why something is failing at run time. Of the major languages, I'd take either Java or c#. Eclipse or VS express, both solid and free IDEs. There are also tons of structured "learn this language" tutorials. Most also start with console apps which are a good place to start. I'd lean towards VS because I prefer visual studio. But from the academic value point of view, I don't see any notable difference between c# and java for the beginner. Obviously you'd go for Java if you're on a mac though.
Contrast that against something like javascript. It can be damn near frustrating trying to understand the DOM, the CSS inheritance, etc. That and simple syntax errors can prevent methods from loading, etc. Sometimes too much simplicity leaves a beginner without any sort of help. That doesn't even touch on browser compatibility.
I run the nightly builds. That's more or less how they display the version. eg: 7.0a1 (2011-06-21). Eventually the version string will end up being 7.0 shortly before release in the RCs.
No... they're saying "hey all you web developers out there, you can make apps for us now too without having to learn anything new! Now whip together your facebook/amazon/ebay website app ports in 1/10th the time it takes you to do so on iphone/ipad!"
You are unconscious while sleeping. If you can't be woken, that's called a coma. At least, it's a coma after some period of time. I'm not familiar with the exact technical meaning of the word. For example, being anesthetized is obviously not a coma. Let me simplify and put it another way. If you're awake, you're conscious. If you're not awake, you're unconscious. While sleeping, you are not awake, therefor you are unconscious.
What are you even talking about? First, these are all videos citizens recorded of crimes happening in front of their eyes in public streets. None of this is coming from the police. If someone is identified, a police expert will evaluate that. If it looks like a match, they'll press charges. If there's enough evidence to convince a judge, they'll be prosecuted. Do you think we run our justice system with some facebook/hot-or-not hybrid? Wow.
As a vancouver citizen, I'd just like to say that anyone who gets into international news for burning a police car, shoplifting, stabbing, etc deserves to be identified. These people are being misrepresented as genuine vancouver canucks fans, rather than criminals who planned crimes in advance, eg bringing gas with them downtown. Since when has asking the public for help in identifying the the people responsible for a crime (in this case many crimes!) been a bad thing? After an amazing Olympics, how do you think we feel having our city shown in this spotlight? I don't know a single friend of mine who wasn't thoroughly disgusted by what they experienced in vancouver last night. If you try to convince anyone from vancouver that this was in any way, shape, or form okay, expect to get a very strong response from those of us in vancouver who love our city.
The perf of an SSD blows away traditional hard disks. For me, my killer app is outlook. On my laptop, I boot it up once every day or two. On my old HD, it would spend an hour downloading/indexing the mail. That made the machine pretty unusable. The ssd flies through indexing and other bulk operations. Also, you never get those system hangs when multiple apps want the hd, causing 'disk thrashing' where the head is flying back and forth and spending all of its time on seeks, rather than throughput. One really really nice benefit of an SSD is that the system is completely usable while the disk is under load. No more slowness while installing an app for example.
But yes, it does extend battery life. The hybrid approach also lets you get many of those perf and battery benefits without spending tons of money. If a disk goes up $50 to massively improve your system perf in common scenarios like bootup/resume, and outlook while also improving battery usage (cuts idle usage down by about 1.5 watts), that's a huge win without sacrificing too much in cost or disk size.
I have no idea if this kind of thing exists today or is under development. But I certainly wouldn't mind seeing airborne disease detectors in high-traffic areas, especially transportation hubs like airports. Having another unique disease to study/detect could have some value while developing tests, vaccines, cures, etc.
Presumably you can sync an android phone to one of these. But going with this instead of windows/osx is a significant lock-in for one's primary computer.
My phone syncs contacts to multiple cloud services. As well, I believe the numbers are on the SIM card. A sync error which deletes ('syncs') the data in all locations is probably the worst for me. I can recover from a broken phone, eg pull out my laptop/ipad in starbucks to call via skype/UC/google voice. It's more the cases I don't think about. For example, if a friend removes their phone number from facebook, I believe that will update the contact in my phone and remove it from there. That's for contacts I don't have in my personal directories. But overall, I think we're a lot safer now than we used to be. Still, I see enough "I dropped my phone in the toilet, everyone send me your numbers!" posts to know that not everyone has a recovery story.
Once the GPU is maxed-out, there's nothing more for the CPU to do. If you're running at 30 FPS at high-res, the CPU might be at 30%. At that point, any number of different CPUs will have identical benchmark results. When you drop the load off the GPU, the CPU hits 100% usage and you can compare 150 fps to 160 fps, for example. This is a very simple and typical way to benchmark CPUs for gaming perf. Reviews and reviewers (such as myself) have been doing this for 10+ years, since the very first 3D accelerators came to the gaming market.

You'll want it for an ARM-based tablet.

At least the Folding@home app still works without PSN. Rejoin and give that dusty old Slashdot team a bump? :)
PowerShell supports remoting now which is nice.
By far your best option. It can take a while to learn though. SharePoint and Exchange use powershell as their main interface for scripting.
Yea, it only has port 80 open.. until you're done hacking apache..
In five hundred generations? Do you really think people will still be giving birth the "old fashion way" in 10,000 years?
