Revisiting Linux Part 1: A Look at Ubuntu 8.04

It's Free – Libre
While the value of “free as in beer” is easy to describe, the value of “free as in speech – otherwise known as libre – is harder to relate. Nonetheless, rather large books have been written on the subject, so we'll try to stick with something condensed.
Virtually everything distributed with Ubuntu is an open source program in some manner. Many of the components of Ubuntu, such as the Linux kernel and the GNU toolset, are licensed under the GNU General Public License (GPL), which in a nutshell requires that any software distributed under the GPL license either include the source code with the software or a way to get the source code. Other bits of Ubuntu are under slightly different licenses with slightly different legal requirements, but the outcome is effectively the same. Ubuntu is free - you can get the source code to it and modify/distribute it as you see fit.
But when we're talking about Ubuntu, there's more than just being able to access the source, as most of the development teams that are responsible for the programs included in Ubuntu have their projects open for public participation. So not only can you take the code and modify it, but if your modifications are good enough they can be submitted back to the main project and possibly be included in a future version of the software. The fundamental idea of open source software is that users are empowered to see how software works and to modify it as they see fit. Other lesser benefits also exist, such as protecting authors' rights by preventing people from taking the code and improving it without sharing it (the GPL), and making sure all the authors are properly credited.
This does not always make open source relevant for the user however. The fundamental benefits of open source software are for people that are programmers, but most users are not programmers. Being able to see and edit the code is not necessarily useful if you don't know how to use it. Even with a background in programming, I would be hard pressed to be able to quickly contribute significant code changes to most projects; very few programs are small and simple enough to be able to easily jump into these days.
Still, there are some definite benefits for those of us that can't throw out code like Linux's chief architect Linus Torvalds. The most direct benefit of course is that this software exists at all. Since all of the software in Ubuntu is free as in beer, paid developers do not develop many of the programs. Open source as a default state makes it easier for people to contribute to the development of software, and that means it's easier for such gratis software to be continually developed in the first place.
Open source software is also a benefit for the longevity of software. Since no one person has absolute control over a project, no one can terminate it. This means that someone else can pick up a project and continue should the original developer(s) quit, as is sometimes the case with old software. It also allows for software to be forked, which is to take the code from a project and create a derivative separate from the original project – the benefit being that a forked project can be taken in a different direction than the original developer may want. As proof of the importance of forking, there are a number of programs in Ubuntu that are forks of older projects, such as X11 (otherwise known as just X), Ubuntu's base windowing system.
Finally, open source software is beneficial to overall software security. If you can see the source, you can analyze it for possible bugs. If you can edit the source, you can fix those bugs rather than wait for someone else to do so - and we can't even begin to overstate the importance of this. The direct relevance to the average user is once again limited here since most people cannot read or write code, but it does filter down through benefits such as rapid patching of security vulnerabilities in some cases. The security benefits of Ubuntu being open source are some of the most important reasons we consider Ubuntu to be secure.
In short: even if you can't code you benefit from Ubuntu being a free (libre) operating system.

I concur - while most of the article is quite good, Ryan really seemed to have missed quite a bit here. His analysis of it seemed rather limited if not misleading.Not everything *has* to be a package - I have various scripts strewn around, along with Firefox 3.6a1 and a bunch of other things without having them organized properly as .deb's with APT. The packaging system is convenient if you want to use it, but it is not required.
Additionally, Ryan made it seem as though everything must be installed through Synaptic or Add/Remove and that there where no stand-alone installers along the lines of Windows' .msi files. It's quite easy on Ubuntu to download a .deb file and double-click on it. In fact, it's much simpler then Windows' .msi files - there's no questions or hitting next. You just give it your password and it takes care of everything else.
The one area I agree with Ryan is that there needs to be an standardized, easy, GUI fashion to add a repository (both the address and key) to APT. I have no problems with doing things like >>/etc/apt/sources.list, but I could see where others may. I suspect this could be done through a .deb, but I've never seen it done that way.

Something I've been fishing for here and have not yet seen much of are requests for benchmarks. Part 2 is going to be 9.04 (no multi-Linux comparisons at this point, maybe later) and I'd like to know what you guys would like to see with respect to performance.We'll have a new i7 rig for 9.04, so I'll be taking a look at a few system level things (e.g. startup time) along side a look at what's new between 8.04 and 9.04. I'll also be taking a quick look at some compiler stuff and GPU-related items.
Beyond that the board is open. Are there specific performance areas or applications that you guys would like to see(no laptops, please)? We're open to suggestions, so here's your chance to help us build a testing suite for future Linux articles.

I'd like to see differences between PPD in World Community Grid between various Windows and Linux distros.I never really see AT talk about WCG or other distributed computing, but I figure if I'm gonna OC the crap out of my cpu, I might as well put it to good use.

Cross platform testing is pretty difficult, considering there are a multitude of different apps to accomplish the same task, some faster, some slower. And then there's the compiler optimizations for the same cross platform app as you mentioned in the article. However, I understand that from an end user's perspective, it's all about doing a "task". So just to throw a few ideas out there involving cross platform apps so that it's a bit more comparable...- Image or video conversion using GIMP or vlc.
- Spreadsheet calculations using the Open Office Calc app.
- Performance tests through VMware.
- How about something java related? Java compiling, a java pi calculator app, or some other java single/multi threaded test app.
- Perl or python script tests.
- FTP transfer tests.
- 802.11 b/g/whatever wireless transfer tests.
- Hard drive tests, AHCI. (I read bad things about AMD's AHCI drivers, and that Windows AHCI drivers were OK. What about in Ubuntu?)
- Linux software RAID vs "motherboard RAID", which is usually only available to Windows.
- Linux fat32/NTFS format time/read/write tests vs Windows
- Wasn't there some thread scheduling issues with AMD Cool and Quiet and Windows that dropped AMD's performance? What about in Linux?
While I'm brainstorming, here's a few tests that's more about functionality and features than performance:
- bluetooth connectivity, ip over bluetooth, etc
- printing, detecting local/network printers
- connected accessories, such as ipods, flash drives, or cameras through usb or firewire
- detecting computers on the local network (Places -> Network)
- multi channel audio, multi monitor video
Just for fun:
- Find a Windows virus/trojan/whatever that deletes files, unleash it in Ubuntu through Wine, see how much damage it does.

I know you've said in previous comments that using Phoronix Test Suite for benchmarking different OSes (e.g. Ubuntu vs Vista) won't work because PTS doesn't install in Windows, but you could probably use a list of the available tests/suites in PTS as a place to get ideas for commonly available programs in Windows/OSX/Linux.I'm pretty sure that Unigine's Tropics/Sanctuary demos/benchmarks are available in Windows, so those could bench OpenGL/graphics.
Maybe either UT2004 or some version of Quake or Doom 3 would work as gaming benchmarks. It's all going to be OpenGL stuff, but it's better than nothing. You could also do WoW in Wine, or Eve under Wine to test some game compatibility/performance.
Once you get VDPAU working, I'd love to see CPU usage comparisons between windows/linux for media playback of H.264 videos. And also, I guess, a test without VDPAU/VAAPI working. Too bad for ATI that XvBA isn't supported yet... might be worth mentioning that in the article.
You also might want to search around for any available OpenCL demos which exist. Nvidia's newest Linux driver supports OpenCL, so that might give you a common platform/API for programs to test.
I've often felt that DVD Shrink runs faster in Wine than in Windows, so the time to run a DVD rip would be nice, but might have legal implications.
Some sort of multitasking benchmark would be nice, but I'm not sure how you'd do it. Yeah, I can see a way of writing a shell script to automatically launch multiple benchmarks simultaneously (and time them all), but the windows side is a little tougher to me (some sort of batch script might work). Web Browsing + File Copy + Transcoding a video (or similar).
Ooh... Encryption performance benchmarks might be nice. Either a test of how many PGP/GPG signs per second, or copying data between a normal disk partition, and a TrueCrypt partition. The TrueCrypt file copy test would be interesting to me, and would cover both encryption performance and some disk I/O.
One last suggestion: Folding@Home benchmarks. F@H is available at least in CPU-driven form in Windows/Linux, and there's F@H benchmark methodologies already developed by other sites (e.g. techreport.com's CPU articles).
Well, that's enough for now. Take or leave the suggestions as you see fit.

you are out of luck here ... linux does not compare to windows because they are both different architectures. you already did what you could in the article.especialy in a binary distribution like Ubuntu, compilation speed tests are meaningless (but Gentoo folks would kiss your feet for that).
boot up times are also not usefull. the init scripts and even init mechanisms are different from distro to distro.
compression/filesystem benchmarks are half way usable. on windows you only have NTFS these days. on linux there are like 20 different filesystems that you can use (ext3/4, reiser, jfs and xfs are the most used. also quite many distros offer lvm/evms backends or software raid.
I do not think there is much benchmarking you can do that will help in linux vs windows, even ubuntu vs windows because the same benchmars will differ between ubuntu versions.
the only usable types are wine+game vs windows+game, native linux game vs same windows game (mostly limited to unreal and quake angines), some povray/blender tests and application comparisons (like you did with the firefox javascript speed).

Not really a benchmark per se, but I'd be curious to know how the stereotypes of Windows being bloated and Ubuntu being slim and efficient translate to power consumption. Load and idle would be nice, but if at all possible I’d be much more curious to see a comparison of task energy draw, i.e. not so much how long it takes them to finish various tasks, but how much energy they need to finish them.In know that’d be a very difficult test to perform for what will probably be a boring and indeterminate result, but you asked. :)

is there some kind of cross platform test that can be done to test memory usage? Maybe Firefox on both platforms? not sure.By "no laptops", I presume you mean, no battery tests (therefore power and as a consequence, heat). That would have been nice though. Maybe for those looking for a 'quiet' setup.
but yes, definitely GPU (including video acceleration) and the GCC vs Visual Studio vs Intel compiler arena (along with some technical explanation why there are such huge differences)

If you can, find games that are reported to work well under WINE and benchmark those against those running natively in Windows. It'd be interesting to see how the various differences between the two systems, and WINE itself, could effect benchmarks.Fox5 - Wednesday, August 26, 2009 - link
Number 1 use of Ubuntu is probably going to be for netbooks/low end desktops for people who just wanna browse the net.In that case, the browsing experience (including flash) should be investigated.
Boot up time is important.
Performance with differing memory amounts would be nice to see (say 256MB, 512MB, 1GB, and 2GB or higher). Scaling across cpus would be nice.
Ubuntu as a programming environment versus windows would be good to see, including available IDEs and compiler and runtime performance.
Ubuntu as a media server/HTPC would be good to see. Personally, I have my windows box using DAAP shares since Ubuntu interfaces with it much better than Samba. And as an HTPC, XBMC and Boxee are nice, cross-platform apps.
Finally, how Ubuntu compares for more specific applications. For instance, scientific computing, audio editing, video editing, and image manipulation. Can it (with the addition of apps found through it's add/remove programs app) function well-enough in a variety of areas to be an all-around replacement for OSX or Windows?
Speedwise, how do GIMP and Photoshop compare doing similar tasks? Is there anything even on par with Windows Movie Maker?
What's Linux like game wise? Do flash games take a noticeable performance hit? Are the smattering of id software games and quake/super mario bros/tetris/etc clones any good? How does it handle some of the more popular WINE games?
