Revisiting Linux Part 1: A Look at Ubuntu 8.04

Things That Went Right
On the flip side of the things that went wrong, we have the things that went right. Most of the Ubuntu experience went right and has been covered previously, so this is going to be a catch-all for other things about Ubuntu that impressed me, but don’t necessarily fit anywhere else.
One of the nicer features of Mac OS X that you don’t see mentioned very much is the Keychain, a credential management framework for applications to use to securely store passwords and the like. Such systems aren’t rare – even Windows has something similar through its Credentials Manager – but Mac OS X is unique in that its implementation at least gets used, at times.
I had not been expecting something similar in Ubuntu, so it caught my eye when a Mac OS-like password box came up when I was logging in to my file server. As it turns out Ubuntu has similar functionality through the Passwords and Encryption Keys application. And since Ubuntu heavily uses the GNOME desktop environment that this application is a part of, a number of its applications are built against the keyring and use it.
It’s not quite as tightly woven as Keychain is under Mac OS X, but it’s better utilized than Windows and used enough that it makes sense to visit the keyring application. The biggest holdout with a stock install is Firefox, which uses its own password manager regardless of what platform it’s on.
Another thing that caught my eye was Ubuntu’s archive manager, called File Roller here. As we’ve lamented many, many times before, Windows’ archive management abilities are terrible. Files are slow to compress, files are slow to uncompress, and just supporting Zip files isn’t quite enough. Mac OS X does a bit better by being faster, but it also has absolutely no support for browsing Zip archives, it just packs and unpacks them. Most power users I know will have something like WinRAR or BetterZip installed to get a proper archive browser and wider archive support.
File Roller is a complete archive manager, and it supports slightly more exotic archive formats like RAR along with the customary Zip and *nix standard of GZip. The biggest knock against it when it comes to archive formats is that it can read more than it can write, RAR again being the example here.
This also brings up an interesting quirk with archives under *nix that you don’t see under Windows. The Zip format specifies it as being both a container for multiple files and a compressor for those files. GZip on the other hand can only compress a single file – so when it comes time to compress multiple files, they must first be packed in a compressionless tarball (TAR), and then the tarball is compressed, resulting in .tar.gz. The quirk is that the Zip format compresses each file separately, while .tar.gz by its very nature compresses all the files together at once; this is commonly known as solid archiving.
Depending on the files being compressed, solid archives can have significant space advantages over individually compressed files by taking advantage of redundancy between the files themselves, and not just the redundancy in individual files. This is also why WinRAR is so common on Windows machines, since the RAR format supports solid and individual archiving.
Now the downside to solid archiving is that it takes longer to pull a file out of a solid archive than an individually compressed archive, since everything ahead of the file must be decompressed first in order to retrieve the data needed to recreate the desired file. So solid archiving isn’t necessarily the best way to go.
Ultimately with the wider support for archive formats under Ubuntu, in some situations it can achieve much better compression ratios than what can be done under Windows. Windows isn’t entirely helpless since when it comes to installers they can use MSI installers (which use solid compression), but as far as plain archives are concerned the only built-in option is individual archiving. It’s a small benefit that can pay out nicely from time to time for Ubuntu.

"Not that it would necessarily be of much use, the last time I saw any statistics for instant messaging network usage, the vast majority of North American users were on AOL’s AIM network."IM use is highly regionalized. As such, AIM is clearly the dominant IM in the USA. However, Canada is dominated by MSN Messenger, and has been for many years (most of us migrated from ICQ to MSN around the release of Windows XP, I believe, due to the bundling of then Windows Messenger).
So, if Canada is dominated by MSN, while I can't speak for Mexico, it's misleading to claim that "the vast majority of North American users". As a Canadian, I can't think of anybody I know in person that uses AIM. They all use MSN or Google Talk without exception.

For myself, the thing that most bugs me when I have to go back to Windows is all the missing features from the window manager. I've come to rely on having multiple workspaces on my desktop, but I can adjust to having just one fairly easily when I'm not working on a lot of different stuff at once. What really bugs me, though, is how much more effort it takes to move or resize windows in Windows. On Linux I can press ALT and then click anywhere on the window, but with Windows I have to carefully click the title bar or the very edge of the window and that takes a noticeably longer time once you're used to doing things differently.Oh, and I find that the Linux scheduler seems to be noticeably better than the Windows one in preserving responsiveness when the system is under load.

Great article!How about some benchmarks of "minimal" distros (like Puppy, Tine Core, ...)??
I like the idea of "ressurect" an old PC, but I would like to see benchmarks in Quad Cores, i7 too!
Anandtech is great, Bench(beta) is awesome!!
(sorry by bad english)
Thanks

A few months ago most major trackers unbanned Transmission, but it still doesn't seem to be universally accepted on private trackers.I remember offhand (I could be wrong) that the main gripe was due to the fact it made excessive queries and thus flooded trackers with requests, or had the ability to.

I think you really need to mention the big picture here.I myself just tried Ubuntu for the first time 2 months ago and although I will admit that I have spent up to 8 hours trying to figure out how to install a specific program (before I found out there was a way to get the package manager to find the install), and I wanted to smash my computer at times. Now that I have learned quite a bit more, I realized that the few things I have installed worked great and flawlessly.
Anyhow back to the big picture. I can understand some of your concerns with how the OS will work with specific programs but what I have found is that most people I know use their computers for 2 things email and web browsing. Most of these people are constantly having problems with the system running too slow and cant seem to get rid of hidden viruses/malware. So I think that those people could easily be much happier with a simple OS like Ubuntu just for email and web browsing (And I would get a heck of alot of less calls from my dad asking my why his computer is running too slow). Lets also not forget that everything is moving to be browser compatible (like you mentioned).
Also, for people like myself, I use my Ubuntu system for a file server as well as a media center (XBMC is Awesome).
So, yes, for burning DVDs/CDs/Playing Games/Microsoft Office, I see no reason why you wouldn't use windows, but I think 95% of the users would be perfectly fine with ubuntu which is something that Mr Bill would not be very happy about when the public realizes this.

I think you have missed one small but important part.I am Ubuntu user since 8.04. I came to Linux because of the constant treat of viruses.
Last month I have installed 7 and it is very user friendly and I think it is very user frinedly but after Avira Antivir got crashed by virus I installed Kaspersky INternet security 2010. then it took almost twice as long to boot. Then I gladly returned to Ubuntu 9.04. Because MIcrosoft can not exist without Antivirus I think you should do some real benchmarking and test windows WITH Antivirus.
On Ubuntu I have ClamWin just in case i get some files from Windows users:)
Thanks

just wanted to point out that you can install software under the LiveCD. Of course it does not install on the hard drive. It remains on a ram-drive, so when you reboot, it's gone. It's still useful, if you wish to test out some package or perform some task with a tool not installed by default on the LiveCDstrikeback03 - Wednesday, August 26, 2009 - link
Even more useful (and not mentioned) is that Ubuntu can easily run off a flash drive, and more recent versions even include a GUI tool for installing it to one. Then all installs and other changes are saved from session to session, and everything runs much more quickly than the LiveCD.Mr Pearce - Wednesday, August 26, 2009 - link
It would be great if you could do more articles on compiler and especially driver performance differences. That was the most interesting part of this article.Ryan Smith - Wednesday, August 26, 2009 - link
This is what Part 2 will look at. I can compile some stuff by hand to see if it closes the Windows/Ubuntu gap, and I have plenty of video cards on hand to test what I can when it comes to graphics.
