[K12OSN] the cat's meow -- thin client

Dear Sir/Madam,

I am writing with regards to documents on your website which refer to
the Open Source operating system Linux in relation with Embedded PC
devices, and I'm wondering whether someone could revise these
documents written in 2004, as many items mentioned in these documents
appear inaccurate or have no reference to solid sources which can
corroborate the information.

I'm referring to the web page at
http://www.chippc.com/support/kbase/answer.asp?ID=CKB00063 and the
powerpoint presentation at
http://www.chippc.com/library/files/presentation/Linux%20TC%203.ppt

One concern I have in the PPT, is with the item which says (Slide 12,
item 1) Claim: "You can get the source code" Truth: "Yeh, good luck.
Ask Wyse or Neoware for the source code and see what you get. Note: MS
provides CE .NET source code to selected vendors"

If you require the source code for the linux kernel, or any
applications which are statically linked against GNU General Public
Licenced (GPL) code, and you are unable to locate this code, then
there is a licencing issue which needs to be addressed by the Free
Software Foundation who will attempt to resolve this licence issue. If
you are referring to an application which they have written in-house,
which is not licenced under an "Open Source Licence" such as the GPL,
then they are not obliged to release the code for this software.

All of the common Linux thin-client stack is released under various
GPL-friendly licences (kernel, X-Windows, rdesktop), although (I
believe) the Citrix client is not released under a GPL-friendly
licence, it is available as a free download for Linux.

I'm also concerned by the comments about Open Source Security, both in
the web page and the PPT. In the web page it says "Vulnerability to
Viruses" "HIGH" followed with the comment "Linux is not standardized
and not secured." In the PPT it says "You have less viruses risks"
"Much easier to develop viruses to open-source OS. Security is big
problem!" While it is easier to develop a virus in an open source OS,
it is also easier to identify flawed code and prevent it from running,
or identify it. A search on "Linux/" in the Sophos virus definitions
returns 4 pages. The same search for "W32/" returns over 600 pages
today.

It is stated in the PPT (Slide 7 - Claim 1) ""Linux will run on any
platform" - So why do I need 196 MB of flash and 128 MB of RAM to run
it on a Thin-client?", then on the web page, specify 64Mb flash. I'm
not certain about Linux Embedded, but Linux on the desktop will run X
Windows on a 386 chip, with 8Mb Ram from a floppy disk. The
ThinStation package will run from an 8Mb ISO image and over PXE.

Slide 26 shows "Local browser" Linux "Bad – Netscape / Mozzila" -
Windows CE "Good - IE 6.0 Embedded" - Why is Mozilla and Netscape
considered "bad"? when there are more security vunerabilities
introduced by Internet Explorer than Mozilla?

It's also slightly worrying that the last slide on your PPT shows only
Microsoft resources, no impartial views? Reviews from other websites?

I've only addressed the main issues that I'm uncomfortable with, but
all these pages seem to show is re-badged Microsoft sales information.
Your products were suggested today on a fairly high-profile Linux
Terminal Services mailing list, but immediately slated as soon as
these pages were turned up.

I hope you can look into either reviewing these documents, or removing
them entirely, as they are not at all beneficial to you or your
business.

Regards,

Jon Spriggs
