Yeah, parent was a troll, and yeah, this is off topic, but seeing as how I'm sitting here in Baghdad, I just want to point something out:
Nobody here who actually picks up a rifle and goes out looking for bad guys is doing it for anything other than the guys fighting beside him. Don't get yourself all worked up about how we've been duped, and lied to, etc. etc.
We know the score. We know what the real reasons for the war are. There isn't much blind flag-waving Bush-terbation here. But we don't have a choice about when and where we fight; we just have a job to do, and lives to save and take in doing it.
We don't want your pity, and we don't want you using us as martyrs in your protests against the government. We want you to leave us alone to do our jobs, and have some respect for those poor bastards who come home minus an arm or a leg or a hand.
Are you kidding me? This is a step in the right direction - I'm looking forward to the day when my *underwear* have an IP address (maybe their own subnet - I have a lot of underwear).
And, c'mon... don't tell me you wouldn't chuckle, running tcpdump on your underwear... That's not just me, is it? Oh, no.
I realize this is getting offtopic, but how could you in good conscience say something like that? I attended a memorial service today for a soldier killed by an IED. I've also carried the bodies of three friends from battlefields in Iraq, all killed by IEDs.
How do you wake up every morning and like yourself?
... the Army really is looking out for my best interests. Here I thought they sent me to Iraq because, due to the "Rumsfeld doctrine" (horseshit), the Army found itself drastically short-handed. Turns out they just wanted me to be safe from the volcano I live next to!
Wait, my family...
Damn. Excuse me while I extract this big green phallus from somewhere intensely personal.

Sun had a great promise. But, it is still a promise. I have seen so much bullshit around that language and half-progrmmers posing as object Gurus etc. etc. made me really sick.
Probably about as many jackasses who think they're hot-shit C programmers because they multiply and divide by shifting. Every arena of knowledge has pretenders. You're not saying anything new.
Now-a-days, when I go through resumes of new/experienced programmer, knowing Java AND not knowing C or PERL is a disqualification to me--these people will never get through the door.
What if they know Java and MIX assembly, and can actually explain every page of TAOCP in plain English? Would you hire that person?
There is no such thing as Java Programmer--either you are programer and program whatever language come in your way or you are just a total waste of space.
Now you're just being silly. There's no such thing as a Java programmer? There must be no such thing as a C++ programmer, either, according to your logic. After all, having an intimate knowledge of a language's standard libraries and the differences between different implementations of that language and its standard libraries is certainly no reason to call yourself a "Java programmer" or a "C++ programmer" or a "C programmer".
I can't help but concede that point. Of course, if you're buying Oracle, you can always tell your boss that Oracle itself has switched its infrastructure to Linux. That's a pretty big selling point to PHBs.
Thanks for casting doubt on my competence. However, tarring up $ORACLE_HOME is only useful if you are replicating an install for the exact same use on a different machine. In my experience, this happens rarely, unless you are installing several machines for RAC. There are big differences in which Oracle software you should install for a DSS machine, an OLTP machine, or a hybrid machine.
As for the silent install, you are correct: this is an option - but only if you've gone through it once before and created an answers file for the install process. And it's really only useful for replicating machines for RAC.
There are few, if any, changes in the driver for Dell PERC RAID controllers. I have both the PERC3/Di and PERC4/DC controllers in my test machine, and have noticed no improvement in IO performance. These devices were plenty fast in 2.1, anyway; I have a PowerVault 220 with 14 U160 disks in it in a split backplane configuration, and with 2.1 I could easily saturate the PowerVault's SCSI channel.
I cannot speak to improvements in the IDE layer, as the only IDE device in any of my servers is the DVD-ROM.
You can buy a development-only license for Oracle9i for $200, but the Personal version of Oracle is not available for Linux. Only Enterprise and Standard. Both of which run into the thousands of dollars.
Well, RHAS is pitched to enterprise applications, and one of the biggest enterprise applications is Oracle. You are supposed to have installed both Sun's 1.3.1 JVM, and Blackdown's 1.1.8 JRE on RHAS machines which are intended to run 9i.
So, at least as far as a JVM goes, the author has a valid bitch.
I run Oracle 9iR2 on RHAS 2.1 machines at my work. Generally, I have been very happy overall with the performance and stability of Oracle on Linux (though, for home use, certainly not - Oracle costs an arm, a leg, and both of their respective prosthetic replacements). There are a couple of things that RHAS 3.0 does much better than 2.1 (that I've noticed, and these only relate to Oracle on Linux, so this may be completely irrelevant to you). All tests were done on a Dell PowerEdge 2650, dual 2.8Gz Xeon, 6GB RAM, a PERC3Di RAID controller driving a five-disk RAID 5, and dual gigabit ethernet controllers.
First, the inclusion of the hyperthreaded scheduler. I run dual Xeon machines, and enabling HT on the 3.0 beta allowed the machine to handle 10-12% more load than with HT disabled. Enabling HT on 2.1 incurred a performance penalty, as the scheduler would tend to starve one CPU.
Second, you can now use bigpages with a shmfs large SGA (SGA > 1.7Gb). My production servers have a 3Gb SGA, and using 4kb pages is painful. I don't know what the problem was with 2.1, but this is a big fix for me, as it means I don't have to lower the mapped base address for all of my Oracle binaries anymore. Woohoo!
Third, LVM is nice. You can use LVM with 2.1, with a little doing, but in general it is a pain. Being able to create volumes at boot time is nice, and then later on, when I decide to hang a PowerVault enclosure off the PowerEdge, being able to just toss that large pool of extra storage into the volume is nice, too.
Lastly, if you are using Java in your Oracle database at all, then you will see a big benefit from NPTL. At least, I am assuming it's NPTL, but my Java stored procedures which spawn threads to parallelize some heavy lifting are executing much faster. I'm probably jumping to the wrong conclusion, but I don't care. Some of my extproc.so's are threaded, and they're running better, too.
I don't really care about Bluecurve, because I never use X on the Oracle servers. The only reason X is installed is because Oracle has no command-line installer anymore, so I have to do a remote X session for the installs. That's Oracle's fault, though, so no digs on Red Hat for that. I also really, really wish that Red Hat would include some more filesystems. Ext3 is okay, but for larger database files, I would much rather be using XFS.
All in all, I think RHAS 3 beta is a significant step forward for Red Hat, at least for Oracle users. Oh, and I forgot to mention that the hanic (High-Availability NIC) daemon from Oracle runs better on 3.0 beta than 2.1. It's cool to be able to yank one of the ethernet cables out of your machine during heavy traffic and have everything keep running.
Who was I making fun of? I was simply responding to the deluge of conspiracy-theory posts, to point out that there is a valid use for the information.
I realize that living vets and ex-servicemembers are the people being discussed. I also realize that it would be an enormous, and difficult, job to automatically "retire" the samples when the soldier or sailor or airman in question leaves military service. It's also made clear to you when you're going through in-processing into the military that they're taking a DNA sample, and that you later have the right to have it destroyed.
Nice use of the time honored "I'll misconstrue your words so I can make fun of you" shtick that's so popular with polititicians and other assorted assholes.
Where was patriotism mentioned in any of my posts? It's a subject you've pulled out of thin air, and attributed to me to support an allegation which was *also* pulled out of thin air.
And why put patriotism in quotes, anyway? Is there something wrong with patriotism? Yes, I do consider myself a patriot - in that I believe in the values and beliefs that this country was founded on. I've been other places, and I know how good we have it here. I also know that our lifestyle and freedoms terrify some people - those people who have no desire to see an end to despotism and oppression - and that America, like every other nation on the planet, needs to defend itself from those people. Who's going to do it? You? Apparently not. So I will, and so will a million other people like me; people whom you hate and denigrate, yet to whom you owe your freedom. And somehow, this willingness to defend our homeland - call it patriotism, national pride, whatever - is a bad thing?
I take issue with your original post, because it accuses me of actions which I have never taken, and will never take. The slaughter of innocents is unconscionable and unforgivable. Say what you want about me, say what you want about this country; that's your right. But don't expect to make horrible, unfounded accusations, and not get taken to task for them. Where's your justification for attacking me anonymously, and without provocation?
Perhaps because I'm not posting anonymously, and I can present a perspective a bit different from that of most/.'ers?
Or maybe because I'm capable of authoring a post without using the word 'fuck' to add weight to a point?
Or maybe people should listen to me because they believe in thoughtful, reasonable discussion, without resorting to casting knee-jerk, uninformed aspersions?
As someone who has his DNA tucked away in the big freezer, I just want to say that I find this comforting. I'll explain, and my explanation can be summed up in two words: unknown soldier.
I'm in a dangerous occupation (19D, Cavalry Scout), in a dirty, dangerous branch (Army) of the military, and I'll be getting a desert vacation for six to twelve months to go police some big chunk of sand in the middle east next year. I'm sure all the airmen, sailors, radio repairmen, hospital techs, and janitors in the service will be up in arms about the government keeping their precious DNA on file, but as one of the low-brows who stands a bigger chance of not coming home than they do - I'm perfectly happy to let Uncle Sam keep two drops of my blood in a freezer.
How easy do you think it will be to identify my remains without a DNA sample if I'm in a convoy that gets ambushed and I get hit by an RPG in the face, and the TOWs in the back of my HMMWV blow up? Not very easy - especially if they don't find the remains for a few years. But, oh, no, it's absolutely evil for the DoD to keep some material on file that would help identify me in that case.
Jesus, grow up, people. Not everyone whose service contract has ended is around to ask for their sample to be destroyed.

But only if the soldier wants to stay in.
