Languages like PHP/Perl, as a rule, are not designed for threading - at ALL.
A few years ago I started getting into PHP to see what it was about and have worked on some PHP sites since then, but this is the main reason I decided to stick with Java for web development.
Page load times can be dramatically reduced by offloading some processing to separate threads. It's great for caching or doing delayed batch writes to the db.
Actually, if he's looking to play around with Oracle RAC, he's looking at virtualization technology to do that without having to buy multiple servers. In that case, Amazon EC2 will be a good idea.
If he's more interested in playing with Xen than RAC, then no.
You can find lots of used servers on eBay that you can mess around with. Sun's v20z servers are pretty cheap and have a decent amount of power.
A lot of the stuff I've run across is rack mounted and keep in mind that rack mounted servers are loud in most cases. So it may not be the best thing to play around with in your home or office.
You don't really need any special CPU to mess around with virtualization, you won't get "full" virtualization but I don't think that will stop you. For more info check out, this page.
I'm currently running a number vm's in my desktop using Sun'x VirtualBox (xVM) whatever they're calling it now. Even within some of the solaris VM's I'm running solaris containers so I'm doing virtualization upon virtualization and my processor doesn't have Virtualization technology support.
If you want to do full virtualization look for server class CPUs. Xeons and Opterons. Using Newegg's power search there is an option to filter by CPU's that support virtualization technology.
If you're primary focus is Oracle RAC, you may want to look at Oracle VM which is Xen based.
I was following the series in the beginning, but haven't for a long time.
I still have the program set in my DVR but haven't bothered to watch since starbuck ran off to find earth and ran into the cylons.
The turning point for me was when they used the term "final 5" in the show. That should have been something for the viewers, and maybe the humans to figure out, but when the cylons didn't know who the final 5 were, that just seemed stupid.
As much as I hate doing so, I have to agree with Ballmer.
These large banks made a real mess of our economy and I reckon it'll take a long time to work things out. The way I see it, the economy grew too fast on nothing but hype, similar to the dot-com era. Except this time, it was much bigger and touched a lot more people.
The government is going to be pumping money into the system to keep it from collapsing before the reality of our economy can come closer to the myth that was pushed the last few years.
This is far from over even though a lot of us aren't even feeling it yet.
This is the ideal situation for FOSS to shine. Maybe a slogan like "Save an employee, use Free/Open Source Software" might be good.
They just want to be accredited to validate their point.
This doesn't make any sense. Creationism isn't a field of study. It would be like being aloud to give out degrees in capacitance instead of having it be just part of an EE degree.
What is there to study anyway? It's just based on what's in the bible.
It's pretty sad really. Like they don't believe the Bible is authoritative enough and they need a state government to give it credence. Maybe more ironic.
There are plenty of skilled and trained people looking for opportunities, especially these days.
Most univiersity programming courses aren't going to teach you all the new web 2.0 stuff. What they do is give you a strong foundation in the field that you can build on.
You normally build on it through internships, part time jobs and other projects you may work on outside the main curriculum.
A degree in the field isn't enough. Messing around in your spare time isn't enough. Someone with the formal training and who works on it in their spare time to learn the new technology is the ideal candidate.
Don't know what you mean about not teaching you trouble teaching skills. I sure learned them through the different CS and EE labs.
I have been a programmer and manager. I can tell you that without a formal training in the field I wouldn't even bring you in for an interview.
Programming is more than just knowing a language. The other things you learn when obtaining a CS degree help you be a better programmer that doesn't require a lot of hand holding.
The only times I've seen this happen have been within a company. If the company you work for has an entry level programming opportunity and you've proven that you have some competency, they may let you transfer and provide some training in certain situations.
But this is like hiring your secretaries nephew to do the company website because people like his myspace profile.
The best thing you can do is contribute to an open source project, as suggested above.
This will give you some real world experience and something you can put on your resume. If after a year or two, you were able to add some substantial amount of code, not just some small bug fixes, you would be in a better position, but would still have a tough time.
AbiWord, Google Docs, IBM Lotus Symphony, KOffice, NeoOffice, OpenOffice.org, StarOffice, SftMaker Office, Corel WordPerfect Office, Zoho Office.
Of those, which is the one vendor that is being favored?
The specification is also open for others to use in either free or proprietary applications. Since the spec is open and there is open software to access the format, the documents created in it should always have the possibility of being accessed.
The ability to switch to open standards and open source software can also save local and federal governments millions of dollars.
If you haven't been paying attention, local and state governments are having a hard time financially. The economic downturn has reduced their income. I'd much rather my government use open source than raise my property taxes.
Finding projects involves a complicated search, information on projects is not actually hosted on recovery.gov
Instead of complicated search, just a pie chart showing a few categories. This money was wasted, this money was not wasted, we have no idea what happened to this money but we no longer have it and I could have sworn we had it.
My HVAC knowledge isn't that great, but isn't the chiller the component that consumes the most energy in an air conditioning system?
Also, if you can run your data center at 104 degF, throughout out of the year in many parts of the country, you could just use a heat exchanger and bypass the chiller?
It's really not so bad. Most drives are rated to about 55deg C (131F), 104F is only 40C.
The key is to design the server with sufficient airflow to try and keep the temperature of the components close to the room's temperature.
Looking at the Datasheet, it looks like they are running the servers on DC power. That way, each server doesn't have it's own power supply, they just hook up to a separate power unit elsewhere in the rack.
The servers don't seem to have fans either. The fans are in the cabinet door.
This setup reminds me of the description of Google's search cluster racks I saw somewhere.
This could result in huge savings. I remember some Sun data center guy talking about one of their new data centers and how they were able to run it at 74F. He said each deg F the could keep the temperature up resulted in 4% power savings.
Sun's problem with swing is not a NIH problem. It's that' SWT is not very Java.
Since 1.5, I haven't really noticed any differences between swing and swt apps as far as performance goes.
I don't really understand what Sun has that IBM wants
.
Java is probably the main thing that IBM wants. Hopefully IBM doesn't screw it up and they keep it open source.
Solaris is more popular and still kicks AIX's ass.
Sun's R&D has been very good. The direction they've been going with their CMT processors and blade servers I feel are better than what IBM has been up to.
If this happens, I hope it doesn't kill NetBeans or any of their other open source projects. Especially OpenSolaris!
What Sun did for open source they did because they wanted to. What IBM did for Linux in terms of the lawsuit was because they had to.
IBM didn't run out and defending linux because linux was being attacked. SCO was suing IBM because of the prior relationship IBM had with SCO on project Monterey (I think that's the name, it's all getting hazy).
IBM was defending itself. Not saying that wasn't good for Linux, but lets not go crazy thinking IBM came riding in on a white horse or anything.
I think you need to double check your definition of 'finaly'.
Sun started as an open source company. Remember the days before netcraft confirmed BSD died? Bill Joy was one of the original founders of Sun.
Sun is probably the largest corporate contributor to open source projects and has open sourced a lot of their own code.
Where Sun and open source didn't get along was with linux, because they thought linux was a toy compared to Solaris. And in many it ways it was. But Linux != all of open source.
You can't just copy and paste your ill informed poasts from 6 years ago. Oh wait, it's slashdot, I guess you can.

I tried getting OS X on virtualbox a while ago but ran into problems.
The latest version I think should work with it because of the Enable PAE/NX option but I haven't tried it recently.
If you get it to work, would you mind posting what image you used?

You guys are so negative.
The headline should be "US Navy perfects underwater stealth technology."
That's nothing.
First that figure is from just ONE affiliate.
Then add in all the money they were making from chargebacks too.

That's favoring one vendor over another.
Hmm... one vendor? Lets see who supports ODF.
