Computing From the Front Lines

What can't Linux do?

My good friend Dee-Ann LeBlanc is looking for suggestions as to what we can't do in Linux. Mostly of course this will be an opportunity to show that there isn't much we can't do; in truth there isn't. I think recent posts by myself, and Sharon Machlis have proved that Linux os not the hugely specialized OS that it is sometimes portrayed as. That's not to say, of course, that everything is easy. Ubuntu makes life very easy, as does Xandros, and books like Rickford Grant's Linux Made Easy demonstrate just how much we can do (read my review and interview for more information). Dee-Ann's query is therefore more to do with trying to determine the gaps so we can focus our energies, rather than trying to level any sort of criticism at our favourite OS. The one comment on that blog post is that there isn't much we can't do; but there are things that difficult. Again, Sharon pointed this out last week with her printer difficulties and there are some desktop things (scanning, for example) which are still less than straightforward for the average user. If you've got anything to add, please let me know by leaving a comment here. Alternatively, go visit Dee-Ann's post and let her know directly.

What People Are Saying

Basically the problems that

Basically the problems that remain with Linux as due to the lock that many companies have on their proprietary software and/or hardware. Jeff's problems with using WIFI for example, are not due to the lack of effort on the community's part, they are due to the lack of support for Linux by the hardware manufacturers who provide neither drivers nor specs to be able to use their devices. When it comes to applications, the biggest missing peices tend to be those closed source applications that are owned by companies like Microsoft, Apple, AutoDesk and Adobe who all have competetive reasons to shun making applications available for Linux. Of course the community wouldn't leave it at that so we try to come up with our own equivalents, but it will take time for things like the GIMP, OpenOffice, xine, etc to get to the maturity level of their closed source equivalents.

Try plugging a WiFi card in

Try plugging a WiFi card in a Linux box and having it detected correctly. I'm all for Linux and in a properly administered network with adequate knowlege, it can be just as good as Windoz. But plug-n-play, it ain't.

There'll always be a few

There'll always be a few wrinkles to be ironed out. Hardware vendors having the nouse to employ developers with Linux skills, a big thank you to NVidia, but most still rely on people whose belief is there is only one God and that's Bill Gates.
To answer the WiFi question, I read an interesting article where a guy was saying how easy it was to use "netapplet" from SuSE with his laptop and get a connection wherever he was, see http://www.linux.com/article.pl?sid=05/09/13/1914255
There's always something new or well hidden in Linux that does the job and I've survived at work for many years using Linux only on my company laptop with Citrix client, wine to run Lotus Notes, OOo, Cisco VPN client and a slew of other Linux apps that ensured I never had to touch Windows and it was as easy for me as it was for the vast number of colleagues using Windows.

How many apps can you run on

How many apps can you run on linux natively without using wine or crossover?

as long as you are using wine or crossover, you are just using windows not linux as many would love to believe.

>as long as you are using

>as long as you are using wine or crossover, you are just using windows

Incorrect. Both Wine and CrossoverOffice are 100% Open Source. You may be running an application coded for Windows, but you aren't running Windows at all. Wine and Crossover Office recreate the Windows APIs natively under Linux (or UNIX).

BTW, many, many native applications run on Linux. The Wine solution is used primarily when an organization doesn't want to change an existing app. Often, you can find an equivalent Open Source app with little difficulty. That's simply a matter of choice.

Is there a CADD program for

Is there a CADD program for Linux that can open/manipulate files from Bentley Microstation or AutoCAD? Is there a scheduling tool like Primavera's P3 or Microsoft's Project? I'm asking because I am a strong proponent of Linux, but relying on Terminal Services to dish out these types of apps may prove rather difficult. And while my experience with VMWare has been rather positive, the idea should be to run one kernel, one OS, not a host OS followed up with a virtual machine.

While Crosssover Office and Wine have made significant strides (as has the Mono Project) the applications I just mentioned are used heavily in design, engineering, construction, and in some cases IT project/program portfolio management. I've been using RedHat since version 5, Fedora Core since version 1, and SuSE Pro since 9.1. (I also really love the AS400 and NetWare and eDirectory.) These are all great in their own way. Still, the issue of vendors not porting their heavy lifters to Linux must be addressed.

Bricscad and Progesoft have

Bricscad and Progesoft have CAD for Linux that can read and write AutoCAD .dwg files. Progesoft is currently available as a free beta, Bricscad is available for a free trial period.
I haven't tried Progesoft, but I believe it is based on the same Intellicad engine that Bricscad is.
Bricscad uses Wine, so I have had some crashes, and have had problems opening some files saved by AutoCAD. Strangely enough, if I open those AutoCAD files in a windows version of Intellicad and then save them again, I can open them fine in Linux.

TNTmips can run on Linux,

TNTmips can run on Linux, can also read various CAD formats. Depending on what exactly you are trying to accomplish you could give it a try. Has been available on Unix/Linux/Macs/Windows for years. A free version is available (limited object size, no export) for student or trial use. Runs on all the Linuxs you mentioned (Redhat needs to be 9 or greater).
