You haven't taken into account the premium that bidders at the barret-jackson auto auction will pay for this in 20+ years. Long-term future prices of collector cars are determined, at least partially, by their scarcity.
They're using this for their message passing, not their web stuff. For example, they accept tweets from sms, internet apps, etc. This system is used to handle all of those disparate messages in a performant manner.
It's not about the calculation it's about concurrent message handling. Millions of people sending messages to them simultaneously.
From the Article: Scala is different from other concurrent languages in that it contains no language
support for concurrency beyond the standard thread model offered by the host environment. Instead of specialized language constructs we rely on Scala's general abstraction capabilities to define higher-level concurrency models. In such a way, we were able to dene all essential operations of Erlang's actor-based process model in the Scala library.
However, since Scala is implemented on the Java VM, we inherited some of the deciencies of the host environment when it comes to concurrency, namely low maximum number of threads and high context-switch overhead. In this paper we have shown how to turn this weakness into a strength. By dening a new event-based model for actors, we could increase dramatically their efficiency and
scalability. At the same time, we kept to a large extent the programming model of thread-based actors, which would not have been possible if we had switched to a traditional event-based architecture, because the latter causes an inversion of control.
The problem is that the programmers think they own the data when they don't. Your app will come and go and the data will remain. People will want to query that data, report on that data, or even transfer it into other databases. Database people think beyond the current requirements of your particular app.
So? You're post up there tried to say none of this was bush's fault. That was either intentionally misleading or uninformed.
The people foreclosing on their homes today didn't get their loans during the clinton years. You seem to not realize that the republicans owned the executive, legislative, and judicial branches for 6 years straight. Bush didn't veto a single bill. For the last two they have just owned the executive and judicial. Anyone with a brain can see that bush and the republicans are major players behind all of this. Are they 100% to blame? Nope. But saying nothing that happened in the last 8 years is bush's fault is ridiculous.
"Expanding Homeownership. The President believes that homeownership is the cornerstone of America's vibrant communities and benefits individual families by building stability and long-term financial security. In June 2002, President Bush issued America's Homeownership Challenge to the real estate and mortgage finance industries to encourage them to join the effort to close the gap that exists between the homeownership rates of minorities and non-minorities. The President also announced the goal of increasing the number of minority homeowners by at least 5.5 million families before the end of the decade. Under his leadership, the overall U.S. homeownership rate in the second quarter of 2004 was at an all time high of 69.2 percent. Minority homeownership set a new record of 51 percent in the second quarter, up 0.2 percentage point from the first quarter and up 2.1 percentage points from a year ago."

Having worked in organizations that suffer from this syndrome, I don't find this definition to be true at all. It's usually a case of arrogance and assumed intelligence over the rest of the world. The people who do this kind of thing have also, at some point in their career, attempted to write their own programming language that is "better". And usually have visions of one day creating their own kernel and/or OS.
That said, there are also times when NIH is required. Google being one example. They deal with more data than anyone. A custom-tailored solution that is only 1% more efficient in terms of time or space is a significant savings for them. So I find this justified in their case. I also commend them on giving their work back to the community.
You may want to consider some other things, rather than blaming senior devs for your troubles. The reality is that company runs the show. The company pays your paycheck. You work for a business. The company invests in whatever software you build. Nobody listens to junior devs about changing languages because the company is not interested in hearing about how they should invest more money to be back to the current point in time with the current software. That's the reason why so many cobol apps exists. Nobody has the guts/balls to go into mission critical systems and suggest replacing them (at significant costs).
The major problem I see with junior devs, and programmers in general is that they think the world revolves around software. Particularly their software. When in reality it is the business that matters. It's the business making (or not making) money to pay you. You are simply providing a service to the company, just as sales people are, or marketing people, etc.
I ordered one of these machines on the day they became available. I had no intention of any extended warranty, I just picked whatever was standard and went with it. Upon the completion of my order I was told that I would receive and email acknowledging my order. I received no email. I checked my dell account and sometimes my information would be "unavailable" or my order "not found". Eventually I was able to see my order and nothing looked any different. I never did get an email acknowledging my order. In any case, I just checked my order for the heck of it to see what warranty I actually received. Here is what I have:
1 950-3337 1 Year Limited Warranty $0.00
1 950-9797 No Warranty, Year 2 and 3 $0.00
1 985-1148 Dell Hardware Warranty PlusOnsite Service, Initial Year $0.00
1 980-3060 Type 3- Third Party At Home Service, 24x7 Technical Support, Initial Year $0.00
1 960-2800 Warranty Support,Initial Year $0.00
Has anyone else thought of the sexual implications of the wii technology? In terms of sex games with devices attached to sexual organs and such. Or am I the only one with a perverted mind...???
"I don't thin there is any way we will be living in space in the next 100 years."
I agree. I always laugh when I hear people say something along the lines of "...living in space when the earth is destroyed". If we need to move somewhere else such as the moon or mars or whatever, won't we have to create our own atmosphere or biosphere or something? And if we have to do that, why would we not just do that here on earth? Seems like it would be a lot easier to a create a biosphere here on earth rather than on the moon.....No?
I've read many of the threads already posted and this is not an uncommon occurrence. Lets just start with the fact that you are not crazy. Panic attacks are not that uncommon. There are many routes to take to solving this problem. My attacks were bad in college followed by a severe attack at my first job. I hate to tell you this, but you've got a battle with your mind on the horizon. After that first panic attack life is going to be hell for a while. Every situation triggers another attack. The fear of another attack brings on another attack. It's a viscious cycle. I am somewhat surprised by your early recognition, but so much the better for you. I spent years thinking I was brain damaged, retarded, insane, etc. Let me assure you that it is unlikely that you are any of these things. Let me also assure that these attacks will pass. For most people avoiding caffeine!, alcohol, and sugar in that order is enough to cure this problem. For me, the major culprit was caffeine. I did not completely give up caffeine, but I control it. I recognized its affects on me and limit myself to one cup of tea a day. The affects of the caffeine in tea are slower than they are with coffee. Recognize that you are different from your friends, not necessarily in a bad way, but you will be affected by substances differently than they will. Such is life.
If you'd like a shoulder to lean on send me an email at logicalmind@<the name of googles email service> and I will get in touch with you.
I think I'm kinda weird but I love listening to the air traffic control channel when flying on planes. I am not really interested in getting into amateur radio but I'd love to be able to listen in from my home. Every time I have looked into doing this it seems to require a lot of knowledge of radio. Can a radio expert explain a bit about listening in on air traffic control or some links about it? In particular I'd just like to listen into air traffic control stations.
And you obviously are forgetting the EULA forbids you from running OS X on non-Apple hardware.
WHY IS THIS SO HARD TO UNDERSTAND? You are not buying the software so much as you are buying the hardware when you buy a Mac. Apple says you can't have the software without the hardware. It's their operating system, they can set terms as they see fit.
I guess I am misunderstanding the reason on why apple would open source any part of their operating system then. I mean, why release the source code if nobody is supposed to compile it, test it, extend it, or use it. Seems pretty pointless. If this is their intention they should really consider changing the name of their "open" source. This basically means they borrowed from mach, and they borrowed from freebsd, and now they're cutting everyone else off.
And btw, you can download xnu without owning osx or agreeing to the osx eula.
Fact: OSX is partially open and partially closed. Many development packages and the kernel have been open source, but the gui and visual areas have remained closed source.
Fact: For the PPC platform this hasn't change.
Fact: The ability to compile the OS X kernel for x86, aka xnu, is no longer available.
My question is, and I have yet to hear an answer, is why have they done this? "Nobody does this anyway" is not a good excuse. I personally compile my own xnu kernels on PPC and x86.
The only thing you can't do is make a bootable Darwin OS for x86 any more. And if you can explain to me why anyone would want to do that for any useful purpose, well, I'm all ears.
One obvious reason is so that you can run OSX on non-apple hardward.
You'll start spending more and more time in OS X, until you--too--become one of the pod people. It's sad to see so many of my compatriots being turned into lemmings.
Strange, I thought lemmings were people who all looked, thought, and acted alike. Considering that windows has over 90% of the desktops, wouldn't the lemmings be the windows users. Anyone who leaves the windows camp to move to apple should be considered an anti-lemming...
I regularly get phishing emails. As soon as I get them I send them with full headers to the particular website. In fact, I've done this so many times that I have added the various "spoof" email addresses for ebay, paypal, etc. websites to my address book. I always get the usual automated response, which is somewhat disconcerting since nine times out of ten I don't have accounts with these people and I am spending my time trying to help them out. In the end I consider it good karma. I hope they find my emails valuable and can stop at least one successfuly phishing attempt or catch one bad guy.
Some people go this route. None of us really have the skill to start a company. At least that is our perception. You know: lawyers, MBA's, accounting, all that stuff. Too much aversion to risk I guess.
I worked with a team of people who really worked well together. We were able to do some amazing things in very short amounts of time. We had a natural chemistry together. Sadly, the company was not very supportive of our efforts. Management figured that since we were all "high performers" we should be disbanded and put on other teams where we could bring other less than stellar teams up to our level. The frustration of moving from a talented and cohesive team to a team of underperformers was too much for many of us. In the end many people left to pursue other avenues. I myself now work for another company. We keep in touch with each other regularly. We are all hoping that in the near future a company will want to find such a team and we'll all work together again.

How about the people who leaked the name of Valerie Plame? Bob Novak, Dick Cheney, etc. Surely you should include those people in your list.
