Revisiting Linux Part 1: A Look at Ubuntu 8.04

Sometimes there is an advantage to not being a large, profit-generating target. If you are Microsoft or Apple, there are some things you just can’t take a risk on doing, the consequences of it backfiring are too great. In this case you would never see either of those operating systems include a BitTorrent client. While BitTorrent is legal, it can be used for many illegal things, making it an enemy of groups like the RIAA and MPAA – both of which Apple and Microsoft need to get along with for business reasons (imagine Windows without a DVD player) and because both have deep pockets should a fight erupt.
Canonical (the company backing Ubuntu) is not a large, profit-generating target and as a result they can get away with more here. We’ve already talked about legality issues encompassing codecs, but BitTorrent is another area where their size lets them get away with more. Ubuntu includes Transmission, a full-featured BitTorrent client, making it wholly unique (at least when compared to Windows/Mac OS X) for doing so. As a regular BitTorrent user, this is a most welcome type of application to include.
With there being so many BitTorrent clients I’m not going to get in-depth with features here other than to say that Transmission is a full-featured BitTorrent client. Instead the fact that it’s included at all is a big deal. Although it’s going to be a slight exaggeration, I would put the inclusion of a BitTorrent client up there with a web browser, an email client, or a media player. I consider BitTorrent an essential function, so a proper client is something that ideally would be included with every operating system. It’s that important.
There is one thing I’d like to add about Transmission in particular though. In my time using it, I’m not convinced that other BitTorrent clients are properly respecting it. I’ve noticed that some other clients appear to be ignoring or blocking it, and while it doesn’t appear to be opposed by a large number of clients, it’s enough that in my completely unscientific testing that this looks to make Transmission slightly slower compared to something like Azureus. Wikipedia notes that a version released over 2 years ago was commonly blocked for not being completely compliant with the BitTorrent specification, but I don’t know if this is related or not.
Moving on, there’s one other thing in Ubuntu that caught my eye, and that’s the inclusion of a Remote Desktop Protocol (RDP) client, going under the name of Terminal Services Client. Not to be confused with VNC, the open source remote desktop system commonly used on *nix systems, Remote Desktop Protocol is Microsoft’s proprietary remote desktop protocol and associated applications. While I had expected Ubuntu to include a VNC client, I had not been expecting a RDP client.
As I have a Windows Home Server for file storage and backing up my Windows machines, I need a RDP client to administrate it and the rest of my Windows machines. By “playing nice” and including a RDP client in spite of the fact that the protocol itself is proprietary and Ubuntu does not use RDP itself, this made Ubuntu much more useful for me straight out of the box. Among other things, with it I was able to immediately connect to my server and diagnose why I was having so much trouble connecting to my SMB shares, something which I’ll explain in greater detail in a moment.
Really the only downside to this is that it’s not as well built of a client as Microsoft’s own Windows client is, which is to be expected. Even on a gigabit LAN Terminal Services Client lags a bit compared to the real thing, but then again so does Microsoft’s official RDP client for the Mac. Ubuntu seems to be at a bit of a disadvantage here since it seems that Windows machines have an inherent advantage in being RDP clients. Nevertheless it’s fully usable, it’s just a bit slower.

http://en.wikipedia.org/wiki/NTFS_symbolic_link">http://en.wikipedia.org/wiki/NTFS_symbolic_linkWell, Windows 2000 had symbolic links for a long time :-p (only for directory until Vista though)

ntfs has symlinks but the windows shell can't create or manipulate them. Pretty pointless. MS can (and does) use them in vista/7 but you can't make your ownEeqmcsq - Wednesday, August 26, 2009 - link
"hint: symlinks are your best friend. My home dir is littered with links to places on the filesystem I visit a lot to avoid a lot of clicking/typing"I use Gnome's bookmarks for that. Those bookmarks even include SMB shares on my other computers.

gnome bookmarks are very handy I just find symlinks to be more flexible since they work regardless of gnome vs kde, gtk vs qt and gui vs cli. Even wine can take advantage of themjigglywiggly - Wednesday, August 26, 2009 - link
one more thing you should have covered is battery life on laptops. Linux in general is pretty awful at managing battery life. Just web browsing 4 hrs on Vista on my vostro 1310(not using 7) but with Ubuntu 2 1/2. It's a huge difference, but oh well.Ryan Smith - Wednesday, August 26, 2009 - link
Laptops are out of our domain, that would be Jarred. If this two-part series is successful, I'll see what I can do about talking him in to putting some Ubuntu (or any Linux for that matter) battery benchmarks in. But I'm told a complete workup takes a while.strikeback03 - Wednesday, August 26, 2009 - link
On my Thinkpad T43, battery life is essentially equal between XP and Ubuntu. Ubuntu may even be slightly better, though I have never bothered with a formal test to put real numbers on both. Have you looked at whether the processor is throttling down properly or not while in Ubuntu?sprockkets - Wednesday, August 26, 2009 - link
"Now we have yet to touch on hardware accelerated playback, which is something we’re going to hold off on until we take a look at Ubuntu 9.04. Linux does not have a common media framework like Windows and Mac OS X have DirectShow/DXVA and QuickTime respectively. Rather the desktop environment that Ubuntu is based off of (GNOME) includes a lesser framework called GStreamer, which is closer to a basic collection of codecs and an interface to them. As such hardware accelerated playback is not as easy to do under Ubuntu as it is under Windows and Mac OS X. We’ll take look at the APIs and the software for this in our look at Ubuntu 9.04."Well, not exactly. There is this: http://en.wikipedia.org/wiki/VaAPI">http://en.wikipedia.org/wiki/VaAPI, which is not exactly widespread yet. nVidia's VDPAU, which provides hardware acceleration for h.264 and if you have the latest version of PureVideo in your card, it does VC-1 as well. It can work with this or alone as well.
Also, while it is wacky that bin or binaries are in one spot, and lib or libraries are in another, and anything you install is in a /usr/lib/local, it does keep all related files in one spot. Keeping all your libraries registered as packages also makes it easy to repair.
Also, one click installs are possible on openSuSE as well, though it does involve a small gui process and adding a repository as well. But doesn't any program require this?
Also, I believe your problem with SMB shares is something I run into as well, but only on GNOME. On KDE, browsing shares is quite normal. Since I never bother mounting the share, I can't directly access it without KDE caching the file locally.
Isn't /home/$Your Name$ intuitive as to where your stuff would be? That is very nice, as I can keep my stuff separate from the OS, thus I can reformat the OS partition without having to touch my data. Imagine reinstalling Windows and finding all your apps working exactly as before with no work. Can OSX do that (not rhetorical)?

VDPAU is something we'll specifically be covering in the Part 2; in fact it's what I'm working on at this moment.GeorgeH - Wednesday, August 26, 2009 - link
I'm sure the comment section will quickly be swamped with quibbles, so I just wanted to say that I found this article to be very informative, accurate (WRT my own Ubuntu experiences), and thorough. Kudos - now it's time to ask for a raise. :)
