Funny people even ask about it. A lot of posters talk like systemd is a brand new scary thing, when it fact it's been in Fedora for a long time. Two and a half years, if I recall correctly.
Actually, it's been three and a half years. Fedora 15 was the first Fedora with systemd and that was released in May, 2011.

Their installation starts Network Manager then explains that if this isn't a laptop installation it is better to not use it.
The installer has used Network Manager for many releases and has doesn't say not to use it outside laptops. Not really sure where you got that from. I use NM on most of my machines - the only place I don't always use it is when I need a network bridge for VMs.
Systemd explains that their binary log format will get corrupted. As if that was acceptable.
not sure it's wise to even touch this one but will is a touch strong. While it's not impossible for journald'd logs to get corrupted, it's no more likely than most other files in the filesystem.

I thought that it wasn't limited to ` but was whatever the key is above tab for the layout currently in use. Then again, I don't know a whole lot about non-US keyboard layouts so I could well be wrong on that one.
I didn't care for GNOME shell at first but it's been growing on me as I use it more. The last remaining thing that I don't like are the huge buttons and menu headers on the windows. I think that it would be possible to hack in some changes for that but I haven't tried.
alt+` on a US keyboard layout (whatever the key above tab is for other layouts) switches between windows of the same application. There are some other good shortcuts in the GNOME shell cheat sheet .

That could only be a good idea for large installations like backblaze. You need to have lots of spares of everything, extra capacity for failures and someone on call to fix the thing when it breaks. There is almost no redundancy and they use consumer grade hardware which means that there will be very regular hardware failures. If you have a ton of the things, this isn't so much of an issue and it probably does end up being cheaper. But using just a couple, much less one of those things would be an exercise in sheer stupidity.
I think that it all depends on what your budget is and what you have access to. You don't need fibre unless its already there and you have the hardware and knowledge to use it. Those cards ain't cheap and would add much complication. Unless you have huge amounts of data (on the scale of several hundred GB or more) changing on a daily basis or can't afford to lose anything at all in case of catastrophic failure, just use the gigE or 100M that is already in place. If that isn't enough, you should really be looking at systems that are designed for remote replication and that gets really expensive, really fast.
Are you looking for an off-site mirror or backups? Those are not the same thing and you need to make sure that you know which you really need. I sincerely doubt that you need to be worrying about recovery time if the building burns down. Just worry about reducing the risk of data loss in the event of failure.
For backups, KISS is the most important thing. If something in the university is already in place, use that. Backup administration is a PITA and you're going to have to hand it off to someone once you leave (assuming you're a student) who may know almost nothing about computers. The simpler the system is to use, the easier the handoff is going to be and the less the people after you will hate you. Someone else mentioned asking the IT department if they offer any backup programs. That would be the best solution, I think. More expensive on paper, possibly but not likely. More expensive overall, I doubt it.
If you end up building a backup server, take into account hardware failures and how much time people can spend to babysit the thing. ZFS has some awesome features, but I don't think that I would use it with anything other than Solaris or maybe BSD. There is no way that I'm going to trust backups to FUSE for linux. Then again, I don't think that ext3 or ext4 would be my first choices, either. Personally, I would probably go with JFS with linux if you have 12TB and growing. Look into external storage arrays. I'm not so familiar with this price range, but HP's MSA 2000 or something comparable might be a good choice if you have the $$$. Just remember to budget for replacement drives if you go the hard drive based route. I'm using a hard drive backed backup solution at work and BackupPC is what I have been using for software. I have been pretty happy with it so far. Its free, it works and has some really good features (like intelligent backup so that it doesn't just blindly store 20 copies of the same file) but has a bit of a learning curve. Nothing like Zmanda's MySQL backup but it needs a little more than a few clicks. I also wish it didn't hit the backup targets so hard but that may not be an issue for you.
I know that there is the temptation to do something really cool and roll your own. I get that temptation a lot, too but you need to ask yourself if you're doing it for fun or to get the job done. If its the former, good for you and I'm jealous but I suspect its the latter. Do the minimum to satisfy the requirements with the least amount of required maintenance and the least cost. Let IT worry about backup systems if you can. That way you can worry about making television programs instead of checking up on the backup server whenever something hiccups or WHEN (not if) hardware fails.
I hope that my rambling helped a little. Good luck in figuring this out.
Comparing XenServer and VMware Server is like comparing apples and oranges. While VMware Server is impressive, it is very much like an emulator: It runs on top of another operating system and has to work harder to execute privileged commands. VMware ESX is a bare-metal hypervisor that is better optimized to do virtualization. While it is still doing "emulation", It is a much better comparison to XenServer than VMware Server is.
TFA is slashdotted at the moment, so I don't know if VMware Server or ESX is being compared. Either way, the advantage of virtualization is not performance, it is flexibility. The raw performance may be less, but it gives you the ability to do things that just aren't possible with a physical machine. The ability to hot migrate from one physical machine to another in the event of hardware failure or replacement and the ability to have entire "machines" dedicated to single purposes without needing an equal number of physical machines are, at best, more difficult if not impossible when not using virtualization.
Don't get me wrong, I'm no VMware fanboy. It certainly has its rough edges and is certainly not perfect. However, virtualization as a technology has undeniable benefits in certain situations. Absolute performance just isn't one of them right now.
Probably because its mostly in Italian on the Italian language Wikipedia and even there, you have to go searching though the discussion page to find more information.
It 'been criticized for giving all city streets contracted to the company "Florence Parking", which made payable most cars, the first free and free. This criticism is exacerbated by the voices of partnership on the board of the "Florence Parking" by the mayor and the wives of Graziano Cioni.
From the mangled google translation of TFA, it looks like he's upset because even though someone else has already been convicted in the "Florence Parking" scandal, his wife is still being implicated on the wikipedia article.
What is the "Florence Parking" scandal? Does anyone else know more details about this?
From TFA (Google Translated):
FLORENCE - The mayor of Florence, Leonardo Domenici, and the municipal assessor Graziano Cioni gave mandate to sue for defamation and slander the web encyclopedia Wikipedia.
The accused - The reason is explained in a note, it's because the "voice" of Leonardo Domenici site charge to the first citizen and his junta some measures and decisions, so it says, "have provoked criticism from citizenship "citing in particular" the trust of citizens in the parking company "Florence parking" for the cda are part of the wives of Domenici and Cioni.
The INVESTIGATION - In the note, please note that this "slander." Had already circulated in the past and that in 2004 the Public Prosecutor of the Republic of Florence had opened an investigation which led to a conviction in a trial. The voice but (when reporting this story) has not changed and is still in the form contested by Domenici. Hence the decision to proceed with the lawsuit.
Dell 'Open-Source' Laptops Well, the laptops do come with FreeDOS installed but I have a hard time believing that there are a lot of people out there running FreeDOS by itself. Personally, I consider these to be OS-less.
Servers also come without an OS. I know that the SC430s have PCIe slots and I THINK that you could pop a video card in there for a good workstation if you wanted (but I haven't done that as I am using it as a server).
Granted, they may not great options but they do exist. What I want to know is why it would cost more for me to buy a Latitude D420 with FreeDOS than it does to buy one with Windows preinstalled. I understand that Dell gets kickbacks for installing other vendor's software, but I don't understand how the kickbacks they receive create more money per computer sold than a licence for Windows.
In the Pacific Northwest, UW refers to the University of Washington...
You did actually read the comment, right?
In Wisconson, "UW" refers to Madison. "UW-M" usually refers to Milwaukee.
He didn't say anything about UW == University of Wisconsin. He was just clarifying the local usage of the abbreviations UW and UW-M. It might surprise you a little, but us midwestern hicks might actually know that there are things outside of our state.
Also, I might be wrong about this but isn't the University of Waterloo also abbreviated as UW? You gonna go lecture them about using Washington's abbreviation, too?
The Badger Herald is an independent (not supported by the school) student newspaper on the UW-Madison campus. Since they don't get University hosting, I sincerely doubt that they spend enough money on servers/bandwidth etc. to survive a slashdotting.

CCP Games calls EVE Online the world's largest game universe. It's a massively multiplayer online role playing game (MMORPG) set in outer space. The service currently has over 160,000 active subscriptions -- more than 34,000 thousand players have been online at once.
Holy crap. 34,000 thousand players active at once? No wonder they need two tons of servers. 34,000,000 is a heck of a lot of people playing at once (not to mention more than their 160,000 active subscribers)/sigh, now I've joined the ranks of your common grammar nazi.
My team just finished evaluating issue trackers, and the final three that we came up with were Bugzilla, Trac and Mantis for both technical and political reasons (Mantis is used elsewhere in the company but that's not saying much since we're so big).
We ended up deciding on Trac because of its wonderful integration with SVN, we are using a lot of python in other areas of our team and it is pretty well documented, there is a great wealth of easy to install (but not always well written) plugins and other than some quirks with the ClearSiler package it is no harder to install than any of the other packages we evaluated. If you use the subversion repository (which can be used for more than code), it is really easy to make links to other tickets, specific documents inside the repository and specific revisions.
However, Trac requires Python (you'll probably want 2.5 as the next release will require it) and either mod_python or fastCGI with a compatible webserver in addition to a subversion repository. Depending on what database you choose (SQLite3 is the default but you can also use Postgre and MySQL but the MySQL support isn't perfect yet) you will have to install the appropriate Python bindings for it and if you install the current stable release you will also need ClearSilver (but make sure you check the Trac Wiki before you install as people seem to have trouble unless they use specific versions of ClearSilver).
If you are serious about using only MySQL and PHP, I would suggest Mantis. It certainly isn't the prettiest thing out there but it does work and does meet your required dependancies. However, if you can swing the extra dependancies I would suggest Trac.
Good luck!
How well does OSX run on only 512? I know that its the standard, but after seeing how well a G4 runs Tiger on 256 (if you can call it running, it wasn't usable by anyone with normal patience), I can't imagine that 512 would be that much better unless you only run 1 or 2 apps at a time. Maybe paging sped up a lot with the move to intel chips, but I still think that OSX is a bigger memory hog out of the box than WindowsXP is (until you start installing stuff, anyways).
I'm a big fan of SuperDuper! since it's trivial to use, does incremental backups and you don't have to worry about missing files or applications if you mirror your entire hard drive.
If you have a firewire external hard drive, you can have SuperDuper! backup your computer's drive to it and if you should ever want to step back to your last backup or lose your laptop's hard drive, all you have to do is plug in the external drive, press option while you are starting up your mac, boot from the external drive, run SuperDuper! to copy all your files back and reboot normally when its done. You are left with a computer EXACTLY like it looked when you last backed up.
It can also handle drives of different sizes (assuming you aren't trying to copy 100GB of files to a 60GB drive) so you can also use it to upgrade your hard drive without needing to reinstall OSX or your applications.
I know it isn't FOSS, but it is still a reasonably priced, wonderful application and I reccomend it 100%
