I might consider it. I've been wanting to get a mac for some time.
I need something to test web development compatibility on, only thing I don't have right now is a mac. I need a malware/virus proof, but not linux (she refuses to do linux, too geeky for her), box for my fiance to surf the web on. I swear she can brick a machine in less than half an hour, twice in one day, even with firefox+noscript and being warned to avoid questionable sites. It needs to be cheap, I have student loans to pay off. Now the added opportunity to play with mac server, tempting indeed?
the computational and storage requirements for editing and storing documents locally are trivial. Even the added cost of an SVN repo for off-site backup and sharing is trivial.
Online document editing can never be as fast and responsive as local editing.
There are severe issues with reliability, availability, security and accountability.
"The Cloud" is imbued with magical fairy dust and can solve all your problems, even the ones you didn't have. You just have to trust that the internet is a nice, safe place to keep all your important and private data.
The letter by RMS addresses that question. That being that the commercially licensed version of MySQL funded suns continued development of the GPL'ed MySQL, and oracle would have a conflict of interest in continuing to develop and license a low cost alternative to its high priced core product.
You are right, EDF would prevent the issue of tasks never getting CPU time. However if your interpretation is correct, it also means that the urgent tasks may not be handled in real time if that 12 hour task reaches 12 hours and still needs significant CPU time. This violates the goal of real time performance if it were to happen. But then again any real time system will eventually fail if put under a sufficiently high load.
Is this type of scheduler perfect? Capable of real time, batch jobs and the mixed fruit bowl of jobs on a typical desktop or server?
The answer is, probably not. There really is no such thing as a perfect scheduler. Different kinds of workloads have different requirements.
A busy real time scheduler will tend to starve low priority jobs. This can become an issue if those low priority jobs manage to grab limited resources they are never given the time to use. As those resources dwindle, real time jobs will be harder to satisfy and the low priority jobs must be terminated or given time to release those resources. I can't really say for certain, but it looks like EDF would have these same kinds of issues.
Interesting story a professor of mine told: An old university mainframe was brought offline after decades of operation. A core dump was performed and investigation revealed that there was a process that had been waiting to run for close to 30 years. Somehow, its priority was set to be lower than the idle process and this particular machine did not have automatic escalation of priority in its scheduler.
Its not going to happen. planets orbit stars, we don't have a single example of a start with a billion planets. The one system we have (almost) sufficiently mapped has 8 planets and a handful of smaller rocks of note. Some of the other systems we have identified could have more planets than that, but we don't have the ability to detect smaller/farther planets at the moment.
The original article was mentioning satellites following/leading mars. With the satellites in mars Lagrange points, the distance would be longer, though not entirely double.
What the hell, I'll bother to do the math this time, using your figures of 150 Gm and 25 Gm that would result in a maximum distance from earth the a mars Lagrange point at about 350 Gm, plus the 250 Gm to mars gives a distance of ~600 Gm vs the strait line of 400 Gm. so its a ~50% increase in time.
Of course I could get pedantic and claim I was talking about the difference in time. But that would be fudging to cover my my lazy ass failing to math.
No. Its a case of historical ignorance on your part. America was going to war with Japan irregardless of Pearl Harbor. The only thing Pearl Harbor did was push up the timetable. It was already planned to take on Japan due to their invasion of our allies in the Philippines and other nations in south east Asia once we had finished with Germany.
The purpose of Hiroshima and Nagasaki was to show the emperial cultists that they would die horrific deaths with no honor, to deny them the glory of their bushido death in battle. It meant that tens of thousands of Japanese died instead instead of tens of millions that would have died when the invasion of the main islands began.
I'm not so sure that Visual Studio is better than the open source alternatives. Eclipse is quite good, and the latest versions of Visual Studio have hidden their keyboard shortcuts, making learning efficient use of the system more difficult.
exactly. In a huge number episodes of ST:TNG, you have a crew of explorers encounter a new and unexplained phenomena. They then explain it, invent a new technology to deal with it and then implement it. All in a matter of hours.
In 5 seasons of B5, the only thing close to that kind of mcguffin is the White Star Fleet. And that took the better part of 2 seasons to develop on screen (with prior work done to its first appearance). It may have been a military and political drama (with spaceships) instead of a story about science, but at least it wasn't a gross perversion of science like ST:TNG.
However, I think you underestimate solar. A solar thermal plant with a heat reservoir of molten salt or high density oil can heat a boiler to spin a generator at night, and potentially for a few days of horrible weather. The big flaw of even solar thermal is that it is fragile. A direct hit by a tornado, hurricane, hail storm or lightning storm could severely damage a solar plant that would leave a nuclear plant practically unscathed.
A good balance of solar and nuclear feeder-breeder reactors would be the best solution in my opinion. It may also be a good idea to tap the yellow stone supervolcano hot spot, though I don't think we could actually do much to keep it from popping its top and killing half of North America.
The copyright term should be fixed. Otherwise, considering the moral quality of most music and film producers, belligerent artists who fail to cooperate might find themselves knocked off and the big companies could then publish their works under the public domain.
A guitar are for picking up chicks in high school and college, it always have been, it always will be. The difference between a professional and an amateur is that the professional keeps picking up high school and college chicks until he gets to old to rock out.
True. But do you really expect such rigor in anecdotal evidence?
But does the typical user have 100 programs if you don't include mal-ware? I was making the assumption that most people would have closer to 10 or 20 legit programs, and the unstated assumption that some undefined number were also incidental pirates with a small amount of pirated software.

The difference is that with online document editing you increase your risks and likely your costs as well, while failing to gain anything.
Unless I am missing something? What exactly is there to gain from online document editing? From google docs or ms office 2010?

why no online version? probably because online document editing and storage is a horrible, horrible idea.
Sounds like as good a time as any to either pick a different thesis project or settle for a liberal arts degree. :)

There are three kinds of people who would use social networking sites to "do very bad things".
1: idiots, there are a lot of them.
2: those seeking to hide in the crowd.
3: those seeking to take advantage of 1.
Neither trolling nor sarcastic. I tend to take things very very literally. Often to literally, as perhaps the case here.

At first i laughed.
Then I realized that you were correct.
Now I am sad.
Why settle for the lesser evil?

sure, except that you are ~doubling the distance the signal has to travel.

I don't know, Apple is trying their damnedest make a laptop that you misplace between two sheets of paper.

I am very much pro nuclear myself.
