It's not always installed in/usr, unless the user takes the defaults on install. Most of the software I use in Unix/Linux is installed in/opt. The config files are in/etc (software that came with the machine) or/opt/etc (software that I've installed). A little planning and architecting at system build time really helps down the road when software must be upgraded and/or removed.
Yes and no. For workstations, laptops, etc., yes, ease of use is very desirable. For servers, especially mission-critical ones, ease of use takes a backseat to reliability. It may take me a little longer to get my Solaris, AIX, or Tru64 machines ready for "prime time," but I know that they'll be solid workhorses when I'm done.
Don't take this as a slam again Linux, *BSD, etc. as server OSes. They're more than capable and very reliable, they're just not currently tuned to utilize the horsepower of an E12k, a p690, or a GS320 cluster.
I can see that for Backup Exec and/or Netbackup, but I'm not sure what Symantec knows about volume managment (VxVM), filesystems (VxFS), and cluster (VCS). I'm afraid that they'll end up like a PC company (Compaq) buying an enterprise technology company (Digital). They'll think they know what they're doing, really not, and hose the entire mess.
As an aside, I wonder how HP is feeling now? They dumped the filesystem (AdvFS) and clustering (TruCluster) that they bought by acquiring Compaq (who bought it by acquiring Digital) and decided to go with Veritas. Would you like your entire server roadmap to depend on Symantec? I know I wouldn't have the warm-and-fuzzies right now....
Is the point behind OSS to "scratch an itch" and solve a problem, or is it to replace MS on the desktop? I would argue that the point behind it is to make good, useful software that solves a problem. I just don't understand how "Free Software desktop applications on Windows represent a no-win situation for Open Source." Is this truly a zero-sum game where one either uses an open source desktop or a closed source one? I would argue that it is not. I use OSS at home (Linux and *BSD), but I am forced to use Windows and Solaris (again, closed source) at work. It's very handy for me to have the same apps (OO, Firefox, Thunderbird, Ethereal, etc.) available on both desktops.
If people are so upset about the iPod firmware update making their Real songs unplayable, then maybe they shouldn't update their firmware. This seems simple enough. The new Apple software won't cause disruptions for you if you don't install it. If you did, then revert back to the previous firmware version.
I'm really curious why this is such a big deal. Apple made the device and the firmware (for a profit), Real reverse-engineered things to get their songs to play (for a profit), then Apple changes the iPod firmware not to play Real's songs (again, for a profit). If this is such a travesty and people are so upset, perhaps they should help Real reverse-engineer things again (so Real can make a profit). This just seems like a p*****g match between two competing companies, which in-and-of-itself isn't overly earth-shattering.
Interesting. In mid 2000 I started working with Tru64 and never had any issues whatsoever with AdvFS. I've had everything from a single internal disk in an old 500MHz Alpha (I forget the model) running 4.0F to 23+TB of storage attached to a two-node GS320 cluster running 5.1 (the filesystems were ~1.2TB each). I've had two high-availability GS140 clusters (one with 4.0F and one with 5.1A) running 4 nines uptime (2.4TB of storage on each cluster, mirrored between cabinets to five 1.2TB of protected storage) and never had a problem with AdvFS. I've also used LSM extensively and, while I can't compare with HP's LVM, I know that I found it _immensely_ easier to use than Veritas' offerings. Just my $0.02.
Yes and no. I agree that Compaq really had no idea what to make of Tru64, but I've still yet to see another Unix that natively has the capabilities of Tru64. The single system image takes some getting used to, but it's amazing that every member can effectively access anything that any one member can see, i.e., if member1 has it mounted, member0 can read/write to/from it. I've also not seen a native filesystem with the robustness of AdvFS. I've personally done a test where I keyed off a running Alpha and fsck of the 23TB attached to it just took a handful of seconds. I have to admit that I've not dealt with HP-UX for five years, but I just don't see it having the capabilities of Tru64. Then again, neither do AIX, Solaris, Linux, *BSD, etc....
Actually, they were. Back in 1997 I had the pleasure of working with the NeXT machines in my roommates' labs. The Cadillac of their machines was a NeXT Dimension with 128MB RAM, 128MB video RAM, a 21" color display, a black-and-white laser printer, a color printer, a scanner, and a soundbox. I saw teh P.O. and that setup was about $18k. They had the lesser machines, a trio of Mono Turbos, alongside it. After working with that, going back home and using my 286 was _painful_.
Actually, the delivery guys will drive out farther than you think. Ten miles isn't that unusual and, unlike the city, it only take about 10 minutes to traverse that distance.
You're right, nothing to see, unless you're interested in fresh air, starry nights, and that absolute quiet that exists out in the prairie. Crap, now I'm making myself homesick....
Absolutely. I was born-and-raised in the rural Midwest and the only reason I'm not there now is because there aren't too many Unix Sysadmin jobs up there.
The thing is that this isn't just an OS X issue. I don't know how many people I've seen use KDE/GNOME/whatever and cheerfully enter their root password whenever asked. Users not paying attention to what's actually happening is a problem on any OS.
I mostly listen to ESPN Radio, 40s music, heavy metal, blues, Air America Radio, old country/bluegrass, and Big 10 football. With the exception of ESPN Radio, none of the others are available here. Plus, the ESPN Radio is only played in part here and pre-empted with local sports crap in the morning. I don't think my tastes are that esoteric, but the local top 40, new country, hip hop, and alternative stations don't play any of that. I also like the ability to choose between genres that I wouldn't normally here. Maybe today I really feel like listening to acid jazz or world music. Good luck finding that on either AM or FM around here.
I have to raise my hand too. I used to be one of the SysAdmins for a bunch of Solaris machines that had to be rebooted every month. The application (crapplication?) was so bad and had so many memory leaks that leaving it up for ~6 weeks would cause system flakiness and/or crashes. We used to joke that it was amazing that Windows was ported to the E450.
If the college owns the building, then yes, they do have that right. Cigarettes and alcohol are legally-owned, yet the college has the right to regulate their use/consumption in buildings that it owns. My cell phone is legally-owned and -used, but the college has a right to regulate its use inside their buildings. I just don't see how this is different.
I'm curious. How did you come up with the conclusion that "[I]n southern states...it is known that [black students] have a harder time finding a job than white students?" I don't mean to start a flame war, but most of the people I hear make this statement are from Europe or the American Northeast and have never even visited the American South. I'm a Yankee, but I've lived in the South (Arkansas and Tennessee) for over 10 years and have known many whites, blacks, etc., both students and non-students. I don't see this trend and have not heard about it from friends, associates, teachers, students, etc. I also don't hear about this from people currently working or looking for jobs. There are some places where I know that it'd be true (certain cities, etc.), but I know as many (if not more) racists in the North than in the South. You can dismiss my comments and opinions as purely anecdotal, but I'd really like to know where your data originates.
Umm, not necessarily. I know that they're in the UK. That's most likely not the only country in Europe where they have an office. Germany comes to mind too, if memory serves.
"We have this too. It works great on IBM's zSeries mainframe. Oh, PC hardware? Solaris can't do that either because the hardware will die if you go ripping out a CPU."
That's a hardware problem, not necessarily an OS one. Intel-based machines don't like losing a CPU and the OS will respond accordingly. When Solaris is running on hardware that will allow hot-swapping of CPUs (e.g., Sunfires), then it works almost flawlessly. The only exception I've encountered is the inability to remove the primay CPU board when running Oracle, due to Oracle's memory management.
This is painfully true everywhere. I've seen systems that really can't be patched. Management won't invest in a test environment, the application uses crappy methods to communicate between boxes (think r-services), and the ancient application requires an ancient OS version on obsolete hardware. The funny thing is that management beats up on the admins for not patching the boxes. Testing in production, that's always a great way to do business.
Sorry, just had a little mini-rant to get off my chest.

If I was feeling particularly jaunty in my old Compaq days, I'd use shutdown -c now. Yeah, that's fun. Shutdown the whole cluster.
