Florida School Deploys KDE/GNU/Linux On Thin Clients

Monday, 4 March 2002  |  Dre

St. Mary's Catholic School in Rockledge, Florida has demonstrated the obvious: that KDE/GNU/Linux (KGL) is great for kids and schools. Working with volunteers from the Melbourne Linux Users Group (that's Melbourne, Florida), I.D.E.A.L. Technology (press release) and IXC Telecom, the school deployed the K12 Linux Terminal Server Project (press release), a thin client enterprise solution. The school's KGL network consists of one beefy server (dual 1-GHz Intel®), which services 36 workstations (16 of which are dual-boot). Apparently the school has opted for KDE as the desktop, and can use rdesktop, a Remote Desktop Protocol (RDP) client, to access MS Windows-based applications from an MS Windows terminal server. The school's report notes that "the cost per workstation was $50.00 using donated Pentium class computers". Time to talk to the local school board about saving some tax bucks!

K12 Linux Terminal Server Project

The K12 Linux Terminal Server Project (K12LTSP), perhaps ironically based on Red Hat Linux, is "free software with the potential to save schools, public agencies and businesses millions of dollars". K12TLSP exploits an extremely efficient, easily-administered system architecture which will ring familiar to those who have studied the City of Largo's deployment of KDE:

K12TLSP installs terminal software on a server that powers diskless workstations (thin-clients). Applications run on the server with only the display, keyboard and mouse running on the workstations. This allows the continued use of older computers while avoiding costly upgrades. New K12LTSP terminals cost less than $200 each. Even greater savings are realized as diskless workstations have no hard drives or software to maintain. While the cost of operation is lower, users enjoy a faster and more reliable software environment.

A typical installation of a Windows(tm) OS based computer lab of 20 workstations may cost more than $20,000 while the same lab running K12LTSP would cost less than than $6,000. Reusing legacy hardware can reduce that cost to less than $2,000.

K12LTSP provides a wide selection of applications most often needed by users. Web browsers, word processing, spreadsheet, presentation and graphics applications are included and are free. Updates in the 2.0 release include automatic sound configuration on many computers. This enables the use of multimedia applications like Real Audio(tm).

Linux has experienced rapid growth as a file and Internet server operating system. It's expansion to end user desktops is not surprising says co-developer Paul Nelson. "No one operating system is the right solution for all tasks but Linux thin-clients are now a superior choice for providing basic desktop applications reliably at very low cost."

Wow - Carbon - 2002-03-04

Well, this is awesome. It demonstrates how useful X can be in an environment like this, where you can't afford individual top-of-the-line workstations, but still want good performance. And KDE in use is great too. I'd just like to know, what office software are they using, exactly? OO or SO, or maybe MS Office via that windows emulation software? It didn't seem too clear on that.

Re: Wow - Triskelios - 2002-03-05

They are probably using KOffice from KDE and/or MS Office through rdesktop. I did not see any mention of Win32 "emulation" software being used; there is just rdesktop, a terminal client (kinda like an X server or VNC client) which can display remote applications from WinNT.

Like a free ride when you've already paid - not me - 2002-03-04

Why is using RedHat ironic?

Re: Like a free ride when you've already paid - Andy "Storm" Goossens - 2002-03-04

Using Mandrake for everydays use seems better to me. (and it makes David Faure happy :-) They use Mandrake but only on stand-alone workstations. I hope they know what they're doing :-) Let servers run RedHat or other distros that are server-centric...

Re: Like a free ride when you've already paid - Marco Krohn - 2002-03-04

Because RedHat was not very happy about KDE in the beginning (to put it mildly). If I remember correctly the RedHat CEO said something like "there will never be a KDE in RedHat...". Then Mandrake was released which was (in the beginning) RedHat + KDE and a couple of months later RedHat was "forced" to include KDE too ;-) Nowadays things have cooled down and RedHat even sponsors a developer (Bernhard "bero" Rosenkraenzer).

Re: Like a free ride when you've already paid - Rob Kaper - 2002-03-05

Bero isn't primarily sponsored for his KDE work, though, AFAIK. But there is a major difference between the visions of Red Hat US and Red Hat Europe. KDE has always been more popular in homebase Europe and this is also true for RH.

Re: Like a free ride when you've already paid - jorge - 2002-03-05

Redhat's "problem" with KDE was the QT license, the same license that kept KDE out of Debian until recently (how long has it been anyway?). Debian, being more vehement about that kind of thing, took longer. And with Mandrake's current releases being a buggy nightmare (I'm hoping 8.2 will be up to the quality of their earlier releases) - I've been recommending Redhat to newbies. Either way, I've been enjoying the Debian KDE packages immensely, they rock.

Re: Like a free ride when you've already paid - fault - 2002-03-05

Yep, I too love the support of KDE in Debian. This was primarily due to one underappreciated man, Ivan Moore. Last time I checked, he wasn't maintaining the packages anymore (other people are), but he deserves a lot of respect for making very good packages and turning the once hostile Debian project very KDE friendly now.

Urban Myth - Moritz Moeller-Herrmann - 2002-03-05

Well Redhat said, they thought distributing KDE was illegal. They then skipped KDE in a few distributions and sponsored GNOME as a replacement for their commercial sucky "Looking Glass" Desktop. They basically fell for Miguel de Icazas propaganda and also wanted to have total control over the desktop environment development, which they would never have with KDE. There might also have been anti-European prejudice and NIH-syndrome involved. I digress. Basically, they proved that the license issue was not the reason for their GNOME support was not the KDE license by including KDE back into Redhat (because of Mandrake) before the license isssue had been resolved. Until this day the Redhat KDE is always a neglected, badly compiled and buggy part of their distribution and it is also the reason why in Europe nobody is seriously considering Redhat for desktop use. SuSE and Mandrake rule here.

Re: Urban Myth - lol - 2002-03-05

1 troll point for you

Re: Urban Myth - ac - 2002-03-05

Badly compiled and buggy? Then why are all these companies using KDE with Red Hat?

Re: Urban Myth - ac - 2002-03-05

Because they are based in the US and Redhat has a big presence in the US?

yes, BADLY compiled and BUGGY. Here's why. - Eduardo - 2002-03-11

Yes, badly compiled and buggy indeed. Horribly buggy. Want to see proof? Go here: https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=54220 This is a bug renders most european keyboards UNUSABLE. If you use RedHat with KDE, you'd better not try to use deadkeys or writing in Spanish, Italian, French, German, Hungarian, Portuguese, and the like. This bug have been present in pre-7.2 RawHide, then got into 7.2, and got through an errata that updated KDE to 2.2.2, to no avail. IT IS STILL OPEN. Red Hat is denying us something as simple and essential as the ability to write our own language. That is why Moritz' criticism of RedHat releases of KDE as buggy and badly compiled are right on target. It is just too obvious that KDE support in Red Hat is just laughable. BTW, I am part of the KDE 3.0 Spanish translation effort. Needless to say, this bug has made my KBabel experience far more "pleasant". PLEASE RED HAT, GET A CLUE!

Re: Like a free ride when you've already paid - Joergen Ramskov - 2002-03-05

KDE will be officially supported in the next version of RedHat. Bero has said that in a post on Slashdot.

Re: Like a free ride when you've already paid - Navindra Umanee - 2002-03-05

It's my fault this is not clear in the article, since Dre actually gave the reason why he said that, but last minute I felt it was a bit too verbose. The reason Dre used the word ironic there is because Red Hat more or less focuses on the Server market and insists on ignoring the desktop. Apologies to Dre and everyone confused by this.

Re: Like a free ride when you've already paid - Carg - 2002-03-05

They don´t ignore the desktop. They spend a lot of resources on it (there´re the packagers, the manuals, and all the traning for their support staff). The desktop is not RH´s focus, but they certainly don´t ignore it.

Re: Like a free ride when you've already paid - concord - 2002-03-11

You're forgiven... just don't let it happen again. ;-)

Ah, this is good. - Timothy R. Butler - 2002-03-05

I love to see it when people take advantage of "KGL" thin clients. :-) What a wonderful, elegant, efficient, solution! Now if only I could set up a few thin clients and one of those SMP 1 GHz servers in my home... Gee, I want to check my e-mail in the basement... no the kitchen... no... -Tim

Debian Jr. - Otter - 2002-03-05

>The Debian Jr. Project is a Debian project to make Debian an OS that >children of all ages will want and be able to use. Well, I wish them luck. Never having successfully installed Debian myself (0 for 3 tries), I'm hoping Debian Jr. (aimed at children 8 and under, according to their site) might be within my capabilities.

Re: Debian Jr. - Keferböck Franz - 2002-03-05

Debian Jr. is not "a more simply debian", installable and configurable by 10-Year-olds, but rather a bunch of packages that makes Debian and Linux interesting for kids of that age! BTW: When did you last try to install? When I first tried, i was scared first, then disappointed that there's no KDE;-) Now there is, and installing Debian is not harder, but just different! I love Debian, and KDE on Debian... MfG Franz Keferböck

KDE making some big steps - Navindra Umanee - 2002-03-05

I say, KDE/Linux is having more and more notable hits like this. Glad it works out, hope it keeps working out. In my opinion though, this is *huge*. Anyone bet we have some people worried out there? Microsoft has been known to go all out crazy in such situations and has been known to give *free* Windows licenses left and right, a touch of political pressure, to get Linux deployments reversed and to get people hooked on their software again. So much for my statement about "not caring" about Microsoft. We've been pretty safe in our niche so far. ;-) I imagine we must be catching the eye of Sun as well? Seems Sun has been making itself irrelevant, but then again I don't think Sun is aggressive about this type of market anymore. Later, -N.

Re: KDE making some big steps - not me - 2002-03-05

The more Microsoft starts going out of its way to suppress this kind of thing, the more it validates KDE as a true competitor to Windows. If we can show that Microsoft is actively going after us, maybe other people and businesses will take KDE more seriously.

Re: KDE making some big steps - Neil Stevens - 2002-03-05

OK, that's nice, but is that all KDE is? An organization fighting against another? Or is it a community sharing and producing software? If KDE is to be thought of in military terms, then that's a real shame.

Re: KDE making some big steps - Hey - 2002-03-05

Generally, software is not made to be disused. If KDE is gonna be used more it will be at the cost of other desktops. It would be great if KDE could unseat Microsoft and be widely used.

Re: KDE making some big steps - Evan "JabberWokky" E. - 2002-03-05

:: If KDE is to be thought of in military terms, then that's a real shame. The Art of War is actually quite applicable to many many facets of life. But I'd like to submit an alternate view: MS is not the enemy, nor is Gnome. The tasks we do are. Ignore the progress of the alternatives like Windows, Mac and Gnome, except for the simple acknowledging them as a source of ideas. Just code KDE to accomplish the tasks you and those you know need to accomplish. Make it easy as possible, and when it's stable, make it snappy (fast) and look nice. ...of course, that's pretty much what's been going on to date. I think the results of that speak for themselves. We just saw the look nice phase hit at the end of the 2.x series, and for those using the 3.x prerelease, I think we're seeing the speed improvements - all on top of the stability we've come to expect. I, for one, don't care if Windows (or Mac) has 99.9% of the userbase - I have KDE, which suits my needs. I'd like KWord to be a bit more advanced, but that's about it (and for those who are wondering, I've used KWord in a realworld, twice weekly publishing with a sharp deadline role. Granted, it was for two RPG groups, but that means lots of text, graphics and layout work for every game. It performed well enough so that I'm satisfied it use it for business purposes now. When the quirks with printing are resolved (in other words, as soon as the current CVS code goes stable), I'll recommend it to others. -- Evan

Re: KDE making some big steps - jj - 2002-03-05

In general I would agree with your statements. Unfortunately, MS is trying everything they can to make my job harder if I am not using their software (like switching to different file formats that I can not read; web sites designed with outlook that I can not view, etc.).

Re: KDE making some big steps - Neil Stevens - 2002-03-05

Unless you're directly doing business with Microsoft, it's not Microsoft wh's making your job harder. It's your employers or customers who make your job harder by choosing to use Microsoft products. Lay the blame where it belongs. Don't treat all the Microsoft users like children who can't think for themselves.

Great news from KDE site - Josue Irizarry - 2002-03-05

I like the idea that the school use Linux and KDE. Because Linux is a great and economical alternative for all the world. Go ahead with KDE 3.0!

KDE/GNU/Linux ???? - Huch ? - 2002-03-05

What's this ??? KDE/GNU/Linux ??? KGL, well that sounds great !!! Has been a long time, exept Debian, someone wrote GNU/Linux. Maybe you gave me a reason to come back to KDE ... Long time i didn't use Konqueror .... I should apt-get install kde*
