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.

Maybe I'm missung something but this appears to be a new article.Why are you reviewing a year-old version of Ubuntu? there's been nearly 3 releases since that (Ubuntu is on 9.04 now with 9.10 coming very soon).
Its important to review the most recent version as Ubuntu is totally unlike the Microsoft world in tnat new releases are frequent (Every 6 months) and have real practical improvements.

I couldn't help myself, but...RTFA!!
:-D
PS: if you read the article, you will also get the joke ;)

Great article. I look forward to reading the follow up.One comment on security that I would like to make. The commercial Linux vendors (IBM, Novell, Redhat, etc.) are all VERY dedicated to ensuring Linux security, as many/all of their server products use Linux, and changes they make will filter back down to the Linux desktop community. This is something that OSX does not have to nearly the same degree.
My experience with running Linux on the desktop sounds pretty much the same as yours.
-Games killed it in general. I don't usually have a top of the line system. So, I'm usually pushing my computer its limits to run newer games under Windows. Also, I hate dual booting, and most of the FOSS I use is available as a compiled binary for Windows.
-Drivers killed it in one specific instance with an older laptop, as I never got NdisWrapper (required for my wifi cards Windows drivers) to run better than intermittently. I spent way to much time messing with it.

[quote]and for the price you’re only giving up official support.[/quote]Ubuntu doesn't have free official support, but neither does Microsoft. Apple does give 90 days free phone support, to their credit, but after that you have to pay.
You can always hire an expert (from ms, or apple, or a third party) to help you, but that's also true with ubuntu, though I expect there are fewer such experts to be found.
MS, Apple, and Ubuntu all offer free web-based help, both community maintained and "officially" maintained.
So I think it's misleading to imply that going from Windows or Mac to Ubuntu means you're downgrading your support options. People overestimate just how "supported" their operating systems are. Also, Linux / Ubuntu releases fixes and updates much more quickly than Apple or MS, so your chances of hitting a bug is lower in the first place. (MS maintains a huge knowledgebase of bugs they haven't bothered to fix yet and might have a workaround for - but I hardly see that as a positive).

I'm probably being too hard on Apple here. The genius bar offers free 15 minute appointments to diagnose problems and offer software tips / advice.I'd say apple has the best "official" support, followed by a fuzzy tie between ubuntu and microsoft.

While I have used computers for 20 years or more, I am not a techie. I am much more interested an experience that "just works".When Vista came out I decided to explore the Linux desktop world. I have been using it as my primary system (still keep the dual boot option for XP) for just under 2 years.
I agree that "free" and security are big considerations for moving to a Linux desktop environment. However, there are some other items (and you might class them under security) that I like - because of the file structure, you don't have to periodically defrag your system. Both systems have a lot of updates, but so far I have not gotten the feeling that my Ubuntu system is gradually slowing down and clogging up with a lot of useless files (you don't see a lot of adds for such utilities as Registry Cleaners:). I no longer experience the MS ripple effect - when MS sneezes, other Windows apps may get a cold.
That is not to say that there cannot be issues. My pet peeve has been that my sound has disappeared on a couple of occassions after downloading updates. Using Google, and the Ubuntu documentation, I have been able to get it back up - but wish that wouldn't happen. But Windows updates can on occassion cause some issues.
I think you made a very valid point about the issue of tech support. Google has made a big difference in problem solving.
Enjoyed your review.

I've tried using Linux (usually Ubuntu) as a full replacement desktop on and off for the last few years. I've gone back to Windows every time after a while. Some key points:1. For my desktop usage, there honestly isn't anything that Linux does better, in terms of functionality, than Windows
2. Windows is cheap enough that I do not mind spending the money on it. For the $100 that I spent for Vista 64 Home Premium OEM, it is quite worthwhile even if I only use it for 3 years. Yes, there are more apps out of the box for Linux, but it's usually easy to find freeware for Windows with the same functionality. Even Office is now pretty affordable with the Home & Office version.
3. Games - Wine just doesn't cut it. When I want to play a new game, I want buy it and play it immediately! I do not want to have to do research to see whether some game would work on Wine even before I buy it. I do not want to spend hours troubleshooting on the internet if something doesn't work right.
4. There's always something that you want to change in Linux that you can't figure out. Yes, usually the solution is on the internet. And I used to even enjoy spending time and looking for the solution. But, it eventually grew old. Now I just want things to work and keep working.
Note that I do love Linux and actually have a server that doubles as a mythtv HTPC setup. It's a beautiful thing. I am comfortable with shell commands and frequently use SSH to perform multiple functions remotely. My opinions above is purely based on desktop usage.

Great article, Ryan! Putting out some well written Linux articles really adds depth to your site. I have been reading this site daily for years and this article is prompting my first post.For future articles it would be great to see some Linux benchmarks in most of the hardware reviews. There are some excellent tools out there (check out http://www.phoronix-test-suite.com/)">http://www.phoronix-test-suite.com/). This would also give some closer apples-to-apples comparisons for Mac vs. Linux performance. I for one would LOVE to see SSD articles report some Linux (and Opensolaris/ZFS) benchmarks along with all the Windows tests.
Users often don't realize how much they benefit daily from open source software. I don't think most Mac users realize all the OSX pieces that are used in the background for which Apple leverages open source code (Samba for SMB access and sharing, Webkit for Safari, etc.). Home NAS and enterprise storage which serve files in Windows environments are often *nix based.
It is also a myth that open source means that developers aren't paid. Most enterprises recognize that implementing even commercial apps can require considerable internal development manpower. If enterprise developers can utilize open source code internally and contribute back to the code base, the companies save considerable money and benefit from a healthy software development ecosystem. There are thousands if not millions of developers employed to work on open source code.
Please keep up the good work. I am looking for your next article.

Unfortunately the Phoronix Test Suite doesn't work under Windows, so it's of limited utility. It's something we may be able to work in to hardware reviews, but it's not really applicable to OS reviews.chrone - Wednesday, August 26, 2009 - link
what i'd like to see on the next ubuntu version is more softer and smoother graphic and font rendering. i hate the way gnome renders the graphic and font. they look old operating system. using the ms core font some how helps but not much.i know there's compiz and friends, but i just wish it comes by default, so no need to hassle with compiz and its setting. i wish it could be rendered softer and smoother such as in windows and mac osx.
the look and feel should be tweaked more often! :D
