On topic but a tangent, what would happen if someone ported GTK (or Qt) to Windows?

According to TrollTech's site, Qt is available for Windows.

If you want to use Qt, be sure to read the license and the Troll Tech FAQ carefully.

As I interpret these, there are two important restrictions:

• You must pay for licenses to the commercial version of Qt even if you only distribute your application internally inside your company.
• You must pay for licenses to the commercial version of Qt before you start your project; if you start developing under the QPL, your software is automatically free software when distributed. (This is perhaps hard for Troll Tech to enforce, but then so are per-developer licenses.)

There are several other, good cross-platform C++ libraries out there, many of the cheaper than Qt, some free (see my other post). I recommend giving them serious consideration before investing much time and money in Qt.

I agree pretty much with everything the above poster said, except that there will be a fee if you intend to distribute your Qt application for money. Qt is only free if you are. If you charge money for a product developed with Qt, then you need to pay the license fee to Troll Tech. This page has all the details.

One of my personal favorites would have to be QT by Troll Tech. This is a cross-platform C++ toolset that cross-compiles into Windows and X code. There are no royalties or runtime costs charged, on any platform.

The popular UNIX desktop KDE is written using the free version of the QT/UNIX development package. If you've used it, you'll probably agree that its fast, comfortable and very solid -- all very important considerations when coding a real product.

This is a very good, clean, serious package. If you're interested in UNIX/Windows cross-platform development I strongly suggest that you check it out.

Troll Tech only gets rights to Qt derivatives (in the sense of copyright law), not to extensions.

3. You may make modifications to the Software and distribute your modifications, in a form that is separate from the Software, such as patches. The following restrictions apply to modifications:

a. Modifications must not alter or remove any copyright notices in the Software.

b. When modifications to the Software are released under this license, a non-exclusive royalty-free right is granted to the initial developer of the Software to distribute your modification in future versions of the Software provided such versions remain available under these terms in addition to any other license(s) of the initial developer.

This also clearly means that the initial developer has the right to distribute your free modifications under their proprietary license ("right is granted to the initial developer of the Software to distribute your modification in future versions of the Software provided such versions remain available under these terms in addition to any other license(s) of the initial developer."). This is a confusing notion, as each piece of the software has an initial developer, so I don't know why Troll Tech takes precedence...

It can't be revenues ($3 million in '99) or profits ($9.4 million loss in '99).

Caldera Systems' products would appear to be proprietary Linux ports of Noorda's, I mean, Novell's successful and fast-growing Netware line plus Red Hat-based OpenLinux distro. The Lizard installer (co-developed with TrollTech) seems to have been finally open-sourced last September under TrollTech's QPL but the only reference to COAS licensing seemed to imply that the source will only be released after the administration tools are developed , whatever that means.

Offering only approximately 5% of the stock to the public is a time-tested method of increasing demand by artificially restricting supply. Ray Noorda (holding 73% after IPO) will be laughing all the way to the bank even if the IPO tanks. Even Sun, SCO, Citrix etc. got their pre-IPO shares at $6 a few months ago while TrollTech got theirs via equity swap. However the common man only "wins" if the company is really going to be worth over $1 billion in the not too distant future. Also be warned that daytraders and marketmakers (both well-known market manipulators) may quickly boost the price quite high after opening but they're also able to dump their "holdings" in a split second when the price starts heading south.

Are people even aware that this Caldera Systems, Inc. isn't the same as Caldera, Inc.? Since they took over www.caldera.com from their mother company any references to the latter have been hard to find. At least they're still proudly carrying a link to the Caldera vs. Microsoft (SETTLED!) page, even though the dough went to the old Caldera, Inc. instead. I hope that the DOJ's case will finally produce Microsoft a guilty verdict instead because it would be too painful to see Gates (unrelated tip: try searching Chairman Gates' site for "Linux") proclaiming again how Microsoft has never, ever done anything remotely naughty, how the operating system and Office suite markets are, as always, extremely competitive and how they only settled to be able to better continue innovating for their customers...

Anyways, it will be interesting to see what impact the nouveau rich Caldera Systems, Inc. will have on Red Hat's market valuation and strategies; both of these primarily server and service-oriented companies are going to be accountable for their shareholders' financial well-being. With Caldera Systems, Inc. IPO already priced above Corel's market valuation perhaps Red Hat should reconsider strengthening their position by buying out Corel (currently valued at only 10% of RHAT market cap), selling Corel's investments in other companies for cash and then creating a number of subsidiaries with their own lucrative IPO's of the Corel product lines as e.g. the WordPerfect Office Corp., the Corel Draw and Publishing Corp., the Red Corel Linux OS for desktop etc. Say what you will but competition between these Linux-based companies is going to get started.
