I have been looking at network filesystem level clustering and failover and NFS, SMB/CIFS and OpenAFS look like good choices for that. With NFS and CIFS you can have an active/inactive fail-over cluster.
I don't know about NFS, but in the case of CIFS, the protocol spec has provisions for renegotiating locks if a connection is broken, but I don't know if there are bugs in win2k/XP clients with samba 3 servers. OpenAFS can have a sort of active/active setup, but the archatecture is such that there is only one server that handles the writes and the rest are read-only. In all of these you can have a semi active/active failover cluster if you move half of the active volumes to the backup server, but this adds a lot to the complexity of your fail-over system.
Those services have a low to moderate amount of state information kept on the server. In the case of a graphical (VNC) terminal server, I don't know of any open source projects that will allow gnome session to be on one server, have that server go down, another server take over its ethernet MAC and IP address and continue processing where it left off on the backup server. The best I can think of is OpenMosix or maybe OpenSSI which are two single system image type clustering systems. If anyone knows anything, please reply and let me know thanks.
The kid developers? The fact is, they don't and probably will not buy a license for DB2/Oracle themselfs. This is where the company should look the other way, because it will be these kids that will push their product in the company they go to work for in the not too distant future.
Now imagine if those KIO slaves were still in userspace but talking to the kernel VFS.
There are projects to make userspace drivers for hardware, and can be used for network protocols also.
True, not everything will provide full filesystem semantics, but many will give the basic (directory, file, copy, move, etc) operations that most people want.
It is pretty hard to tell the difference between the phishing scams impersonating and what paypal may have done with accounts.
I plan on using paypal in the future, but will only connect them with a bank account that does not have a lot of funds in it in case something does happens.
I'm posting to myself, but why was that marked funny?
Netcraft would be lynched if they showed the number of machines (really all they can do is count IPs) are running Apache compared to IIS. I'd unhappily bet that they were equal or IIS was in the lead.
The fact is that the Linux kernel is not just C, it also has parts where it uses assembler because they don't trust even the C compiler for that part of the code.
The fact is that in the kernel much of the low level code cares about the exact physical layout of memory, and if it were mostly C++ you would need more parts in assembly which must be ported to each archatecture.
Yes, C can be used in a higher level, but you are calling functions that deal with the low level from there is a very much OO way.
Also, when you see people benchmarking how many cycles a processor actually takes to perform a snip of code and analyzing the assembly of the C program, I sincerely doubt that they would not be able to do the same for C++.
They find problems and fix them and all other references to such code that is in the kernel tree.
The only problem is if you don't have your code in the tree and if you don't that's your problem.
Also, if you are doing any development, you know not to change your base often. That means if you are writing a large subsystem, you are not doing so on the latest kernel because you won't know what bugs are yours and which are introduced by the base kernel update.
Come on, netcraft is just skewed statistics in the favor of OSS.
You are counting the same server multiple times because hosting providers use Apache for the most part.
Anyone who has worked in your typical office, will be waging a constant fight against IIS and MSSQL because that's what most of the companies are selling to shops that aren't big enough for Oracle.
Apache has not won the war. I say that to keep anyone from giving up on that front.

" Because in FreeBSD, it's possible to update a shared system library without rebooting the computer. Among other things..."
The NT kernel has this feature also.
They just aren't using it very well yet.

They obviously don't see very well, they're smiling at you... ;)

And here I thought when it said "download a pattern" it meant strapping down the pumpkin and uploading the pattern and poof an arm would carve it out.
C'mon, wouldn't you rather hack on the code than carve it physically? j/k
Just to confuse whether you should give funny or insightful points...
How many have noticed that people who could design a system (or a pattern) that could automatically carve your pumpkin couldn't do it by hand?

Is it true this comes from the simpsons?
Because if it is, please tell me so I can wring homer's neck TYVM.
Hosting providers use IIS only when they *have to*.
That means there are more web sites on the same apache server than web sites on IIS servers.
You end up with a higher ratio of web sites to server with apache, and lower with IIS which means IIS may be on more servers...
Also, most of the fscking web based software sold to small business is based on IIS. And that shouldn't be exposed to the internet.
Naw, just put them on the floor on their side and use them as a dust mop.
No need for anything sharp like your paint roller... *Shiver*
"I forget which command, but one command for the 8086 required 83 clock cycles to complete."
So what's changed? You can get that with a Pentium 4...
Well, the mouse driver is open source, just fork that and you're set....
No, it will be MPL/GPL/LGPL.
No, msearch or firesearch would be better.
Just try saying mozsearch three times fast...

So the linked article is trying to paint the Democrats as the good guys?
I'm sorry, but in my lifetime (born 1981) every president has had foriegn military actions performed during their time in office.
