Just as a followup. After reading more about EC2 instance types, the amazon term is compute unit. However, they don't give any hard numbers for the Hz of the machine (just "One EC2 Compute Unit provides the equivalent CPU capacity of a 1.0-1.2 GHz 2007 Opteron or 2007 Xeon processor.") and they don't give any GUARANTEEs that the compute unit won't be diluted over time.
Amazon's instance types (http://aws.amazon.com/ec2/instance-types/) doesn't seem to indicate the number of cycles/sec you are guaranteed to use per type.
They sell instance types based on the physical hardware specs which is worthless in a cloud architecture. What they should really be doing is indicating the number of cycles/sec an instance type will be GUARANTEED and then enforce it. If the customer doesn't use that number of cycles/sec, then fine put the idle cycles up for bidding.
To be fair though, part the reason you probably hadn't heard about it is because the world's media was mostly too busy covering middle east stuff like Israel's war with Lebanon.
I think the reason for this is that its a lot less fun to be a reporter in Darfur then it is to be a reporter in Tel Aviv. If you are a reporter in Israel, it's only a 3 hour trip from Tel Aviv to the Gaza strip or to the north, you get your news story about the horrors of conflict between the Israelis or Palestinians or Lebanese, and then you drive back to Tel Aviv, send off your report, and then go partying in Tel Aviv all night. Rinse and repeat.
It the malicious circuity has to be triggered externally and it's unknown when it'll be used, that means that either: (1) hackers have to get into a network linked to the hardware or (2) there has to be an external radio signal which can disable the hardware or (3) The hardware (radar in this case) doesn't validate it's input well enough and is open to buffer overflows/ bad execution based on invalid input.
From what I've read, the Israelis exploited (3) in order to disable the syrians radar systems. It seems to me that the syrians bought just plain crappy radar systems and then never bothered to test or "fuzz" them.
However, the article seems to be going crazy over (2). However, a simple faraday cage should be good enough to defeat that kind of attack. It'll create a barrier between the inside of the container and the outside. No EM radiation goes in, no EM radiation goes out. Any kind of circuity triggered by EM would be defeated. And by definition, any circuity triggered by time is useless because it's impossible to determine when in the future, it'll be required.
And (1) is easily defended against by not connecting your critical defense hardware to any network of any kind. Or by using 3rd party firewalls which have not been made in China/Russia/Iran...
The author merely asks the survey participates to rate their mathematical abilities without actually testing them. I wonder about the correlation (probably negative) between people who rate their math skills highly and people who actually can do math.
This study should be titled "Correlation between people who have high self esteem and who thinks that this child pornography prosecution is stupid."
While service isolation is easy on Unix platforms, it's not on Windows.
I don't think it's even that easy on unix. I had to install a lot of custom packages on our Suse machines at work to get reviewboard up and running. With that level of customization, I won't dare try to get another service running on that VM. Also, another awesome benefit to VMWare's concept is that it's trivial for me to clone the machine and setup an identical machine to test doing an upgrade. After that, I'm a fan of VMWare server. Of course, the service is not bandwidth intensive so the issues are different.
I used to work at an animation studio where they outputed 27 different pass PER FRAME just for compositing. And this was a small, no-name animation studio in israel.
God knows how many passes pixar or ilm produces...
The point is that Murdoch has revealed his true colors as a media giant and not as a respectable news business that'll protect it's journalists when they mess up.
Remind me to ignore news postings for News Corp because obviously they are biased. Especially ones relating to the effects of piracy on the economy, small artists, big artists and most importantly THEMSELVES!!!
Maybe AT&T and Verizon were worried that the VoIP providers would switch to other common carriers like MCI and Sprint if they only cut off the service.
Maybe they wanted to crush all of the businesses at once by grabbing as much expensive hardware as possible.
Wow, the FBI really do sound like a bunch of paid-off thugs in this scenario...
Here's a simpler conspiracy for you:
AT&T and Verizon have very good working relationships with the FBI due to the wiretapping business.
AT&T and Verizon aren't being paid for the bytes being sent over their wires. So instead of waiting for the
real collection agents to try to collect and let the normal court system do the job, they tell the companies to pay up
or they will send the FBI after them.
The internet companies don't believe them and call their bluff.
After a couple of months, AT&T and verizon go to the FBI and request a raid because of a "massive fraud scheme against" them.
The FBI dutifully goes in, grabs all of their equipment (their standard modus operandi) and walks out.
The customers are pissed but if they were smart, they had everything on backups in secret vaults.
AT&T and Verizon have just lost a ton of paying customers and are about to be slapped with several large lawsuits.
QWest, MCI, sprint and covad get a ton of new business.
So Verizon digging out their old copper wires and putting in fiber is a GOOD THING!
Imagine if only the cable company (Comcast here) could offer ultra hi-speed internet.
Since we (the US) don't require the cable companies to be common carriers (http://yro.slashdot.org/article.pl?sid=05/06/27/1510219) then customers wanting hi-speed internet would have only one place to go.
I congratulate you, as you are clearly an intelligent audience
So did i, but that didn't prevent me from reading the book. Actually, It's my current bed-side reading. And so far, so good. The author is funny and really seems to know his stuff. He writes from the heart.
CLI is faster the GUI but requires much more memorization and has no context which the user can start from. Also, it's harder to control stateful programs using cli IMHO.
If ubiquity manages to reduce the memorization task (by making the options constrained and having a drop down to select from with help), then it could be a big win. It still has the problem of being difficult to manipulate data in a stateful manner...
I know that a lot of people here are dissing 4.2 as buggy and unusable but on my Ubuntu 9.04 laptop, it rocks!
I have tons of graphical eye candy and it's super easy to add/remove plasmoids. Probably, the system bar icons should be movable to plasmoids seamlessly, but mostly the whole package hangs together well. The audio worked out of the box and the volume setting is visible when you change it. (Note, I had to manually change the control to master, it defaulted to pcm)
The compositing eyecandy is great and adds a little more bling. And so is the screen switching. Now I just need to stop reading/. and get back to hacking krita.
Israel's number one money maker is the ideas and developments of it's people, mostly in the form of software, more then tourism.
When your country doesn't have any significant natural resources and doesn't have friendly neighbors to trade with, it tends to develop a very robust intellectual infrastructure. Plus, most of it helps the defense industry. You'll notice that the entertainment industry in Israel is quite small.
i hate to troll but after looking at a comparison of C# syntax vs D syntax, I get the feeling that they were both invented to be the "GC'ed, nicely templat'ed, clean syntax" upscaling of C++, similar to what C++ was to C.
However, C# has the backing of M$ and D doesn't. So in my mind, unless a miracle happens (like Qt turns out to be the primary GUI of choice for D and WPF turns out to be a REALLY bad idea) D is dead in the water.
Disclaimer: I have tasted the white lines of C#+WPF and let me tell you, it is 100% pure coding goodness. I dislike M$ as much as the next person but when it comes to getting the job done, C# delivers strongly.
Nobody needs files? How, exactly, can I retrieve a document then? This FA is damned short on details.
I doubt they're going to disallow serialization. that's required to transfer data from computer to computer. However, it would be interesting if the OS had the ability to save out the complete history of a file to be transferred. Then once the file is deserialized on another computer, you'd have the file fully restored.
So the article does have some good points. However, the authors seem to have very bold predications about how awesome their OS is going to be. It'll be interesting to see how far they get.

I have 4chan.org on my droid with no wi-fi. They must have unblocked it by now...
Wow, surprise surprise, android is open -> easier to teach kids how to program it...
Remember that you can always vote with your dollars.
And if apple doesn't provide the devices and features that you need, someone else will.
I think that Jobs is getting cranky in his old age....
heh, except that the fuel pellets use tritium and deuterium and the containers (hohlraums ??) are made out of gold foil.
You don't find these elements at your local 7-11....
I'd be interested to know how much tritium and deuterium a fully functioning fusion machine is expected to use up...

Of course the flipside is that it's easy to oversimplify and ignore feature which don't fit inside your design.
From the user's POV, the engineer is not being responsive to his needs and the application is "broken"
So, yes, simplisty is awesome from a maintenance engineering POV but actually kinda sucks when the feature just needs to get done.
To be fair though, part the reason you probably hadn't heard about it is because the world's media was mostly too busy covering middle east stuff like Israel's war with Lebanon.
I think the reason for this is that its a lot less fun to be a reporter in Darfur then it is to be a reporter in Tel Aviv.

What the heck type of fun is there in Darfur?

So I say to verizon, dig baby dig!
I think large companies drift on inertia a lot.
No one wants to rock the boat or tell their manager that times are changing.
I bet that the head haunchos at the cable companies are trying to be exclusive with their content so they can charge a high premium for it.
I dont know. Most regular tv/movie media pisses me off and if its something that seems really interesting, I add it to my netflixs queue.

I've no idea.
WPF is a pretty good GUI system, very configurable.
I think there's a project to porting it (olive) but it looks like its moving verrrry slowly..
If you're working on maintainance jobs all of the time, then that really sucks. Maybe you should request a change in position from your boss.
However, being the lead on a new project is pretty rare. Most work is adding an feature, fixing a bug, etc.
I'm fortunately at my current job to be the lead on a new project. But ultimately, it'll just be a front-end to a current existing system
Just my two cents.
