Unfortunately a lot of developers and companies who are publishing code under open source licenses do not get what open source means to their code: You are giving away a lot of control. The less viral the license, the more control you give up. Up to the point where you are basically donating them to the public with no moral or actual right to be compensated for it.
If you want to fully control monetization, keep your code proprietary. But then good luck with having to pay developers for every single line of code and every tiny little bugfix. No standing on the shoulders of giants.
Face it: If you want to build a business on open source, trying to fight others who make use of your code is futile. It is often unfair itself as well: Because there hardly is a successful open source project that has been possible without countless other open source projects that came before it. Projects that created the tools, programming languages, libraries and frameworks that make your own work possible.
If you take that upstream code for granted (which you would have to make or buy if it was not open source), you should also take for granted that others will take your open source code for granted and make money with it without caring for your precious montetization strategy. This is not unfair. It is playing by the rules. The rules just are not built to protect the interests of the original authors of the code, but to protect the freedom of the code itself.
I just checked what I could find about wind turbine recycling in Germany. First, as I had expected, the cost of removing the turbine after its end of life is factored into the costs from day one. So when the time comes, the owners have to have reserves set aside to pay for the destruction and removal of the turbine. Second, many turbines can still be re-sold and get a second life in another wind park. Third, even today there is a complete recycling chain in place for everything from the concrete or steel of the towers to the blades. The blades are shredded and are used as fuel for cement manufacturing. No landfills involved, except for the ashes. The metals that can be recycled are covering a lot of the actual recycling cost, so most operators donâ(TM)t even spend all the money set aside for removal. Improvements in recycling will further increase the overall profitability. I am not saying that this is not a problem in the U.S., but it is a problem others have solved with the right accounting principles and technologies.
Renewable energiy isnât a toy, but a reality: https://www.energy-charts.de/power.htm?source=all-sources&year=2018&week=26 https://www.energy-charts.de/energy_pie.htm Here in Germany weâ(TM)re close to producing 50% of all electricity from renewable sources. And thereâ(TM)s a lot of free roof space to add more solar panels. What these production charts donâ(TM)t show is that we are currently producing much more energy than we consume because the coal and nuclear plants canâ(TM)t easily shut down when their power isnâ(TM)t needed. So, in terms of total power consumption, once the storage problem is addressed, the solar and wind peaks, together with the bio gas and water plants that can be shut down in times of over-production, can be used to deliver energy all day and night.
Firefox is not GTK based in the same sense Konqueror is Qt-based. It has its own graphics toolkit (XUL) under the hood of the GTK UI, and it does not use GNOME infrastructure to extent Konqueror uses KDE infrastructure.
But I looked up the (somewhat outdated) numbers I remembered, and you are right in the particular case of XFCE + Firefox vs. KDE + Konqueror:
>> KDe takes less RAM iff you use Konqueror iso FireFox, and KEdit iso OpenOffice. Mixed suites eats RAM.
> Gold truth, but I'd have settled for something XFCE based maybe (Xubuntu comes to mind).
As far as I know, KDE with Konqueror is more RAM-efficient than XFCE with FireFox. XFCE and other small footprint window managers need less RAM if you run them without apps, but as soon as you need apps, a single toolkit solution (KDE with KDE/Qt-only apps or, to a lesser extent, GNOME with GTK-only apps) will be more efficient because they share their libs.
GNOME is the default you get. But there still is a full KDE desktop option, on both SLES and SLED. YaST is still Qt 3. There is a Google sommer of code project for a Gtk-based frontend, but that's all for now. Zen is mostly written in Mono/Gtk#.
People are looking at mass-migrating certain types of desktops to SLED already. Of course this all takes time, but considering that a large part of many companies' desktops is used for accessing the web (intranet and/or the Internet), mail/IM, and running office productivity apps, we are almost there.
The Active Directory integration mentioned in the article is a big step. Now a Linux desktop can be used in a Windows server environment without changing anything on the server or running additional software on the client. This includes passwordless access to Microsoft IIS web servers, Outlook Web access, file shares etc.
Windows may not cost $300 in the enterprise, but Windows + MS Office certainly do. That's what you get for SLED's $50, not just the core OS. And if you are a corporation, you will quickly find out that you can get even better pricing from Novell.
Well, most of the relevant parts in a good groupware client are "GUI stuff". Speaking for Kontact/Korganizer, the plugins for linking up to the groupware servers are relatively easy to port, at least if Lightning comes with a suitable plugin concept. The question is why one should do that. With two mature groupware solutions being available (Kontact and Evolution), why should one start developing a third one that doesn't even come with a new approach on collaborative work?

pound (http://www.apsis.ch/pound) is a good and very secure choice. It was developed with Zope in mind, but can be used with any other http server.
pound sanitizes http requests, does load balancing and logging, and can SSL-enable your Zope site.
One thing is missing almost entirely in this thread:
The RDBMS people come up with examples like integrating large legacy databases, and working with OLAP tools etc. This is just one application domain. It's an important one, but not the only one.
There are a lot of situations where one wants to have persistence in a complex application. To get that by storing the data in an RDBMS seems to be less than desireable.
The point I want to make is that whether OODBMS or RDBMS or a combination of both is best is mainly dependent on the actual problem domain!
BTW: After reading all the problems people seem to have with their commercial OODBMS, I have an even better opinion about Zope's free ZODB. It has done a great job for me so far. With Zope's ZCatalog indexer you can solve a lot of the problems OO might bring.
You CAN do Updates from YAST2 now. The limitation was only for SuSSE 6.3. BTW: YAST2 is not graphic ONLY! It'll work in a text mode, too, if necessary. E.g. try "minimal installation" (which doesn't install X) and you'll see YAST2 text mode at the end of the procedure...
It might well make sense to cache Zope content. If you set the right header information, the pages served by Zope won't LOOK dynamic, even if they are. Of course this only applies for content that is not dependent on user interaction. But in the case of dynamically generated language versions of "static" pages it would be fine. BTW: Apache can be used in reverse proxy mode with Zope, too!
A concept that has worked very well for me is using "non-functional" prototypes -- in other words: demos.
The problem I had to solve was an Intranet database project. Just "drawing" a front-end that looked and feeled as if it worked (using a graphical HTML editor like Netscape's or MS Frontpage) helped a lot. On the demo you can simulate how the thing will feel for the user.
I wouldn't recommend MS Frontpage for any serious web page design, but for those quick hacks that don't have to be compatible with older browsers it works very well.
AFAIK there are unfortunately not too many open source graphical design tools that offer similar functionality, either for web programming or "serious" coding.
Of course this approach only works if your program is going to have a GUI;-)
... and some pre-prototype paper-based design still is recommended.
Please try first and comment on things afterwards! I just double-checked it: Win 98 DOES format the disk if necessary. Its not THAT dumb. I guess thats one of the problems non-open-sourcers have with "the community": Not sticking to the facts when criticizing Microsoft stuff!!!!!
There is so much talking about how easy to install Win98 is compared to Linux in this discussion thread.
I installed Win98 some days ago (in a vmware box running under Linux; sorry, but I need it for checking web page designs under MS IE...)
It still starts with a blue text screen for the basics (HD config etc.), then boots a Win3.1-based (looks like Win3.1 at least) installation program and finally starts Win98 for the first time. Win98 still doesn't detect your VGA card during install and takes a real lot of time and several reboots.
I would NOT recommend installing Win98 to a PC novice. The point is that most of the PC users never see a "bare" PC with no preinstalled Win.
If you have, let's say, SuSE 6.1 with the KDE login manager running preinstalled, that should be quite usable for PC newbies, too.
I personally like what I SEE an the Caldera screenshots. I have not tested it yet. But I am sceptic if Caldera Linux is THAT well-configured in all details as my SuSE 6.1 with good, whilst not perfect YAST install.
And: At least at the moment the installer is fully copyrighted! The license sounds like the MS ones. Let's see if that REALLY changes soon.

NT vs. Linux: Again
·
· Score: 1
Hi folks!
I think one has to accept that at the moment NT is slightly faster considering the maximum output of a web or file server.
But as German PC weekly "ct" found in their own benchmarks (issue 13/99, pp. 186), Linux is still a very good choice under real world conditions. They tested SuSE Linux 6.1 and NT 4.0 SP4 on a 4-XEON-450 Siemens machine. The main difference between their configuration and the Mindcraft one was that they just had one Ethernet card (instead of FOUR!)in the system.
They said it was not realistic (except for a few Intranets maybe) that a web server has to serve more than 100 MBit/s or even more than 10 MBit/s. Under these circumstances Linux was slightly faster with static web pages and much faster with serving CGI. However, ct didnt test MS IIS with ASP (hard to find a fair benchmark between Perl/CGI and ASP anyway).
Only when they tested the system with a second Ethernet card, simulating similar loads to the ones in the Mindcraft tests, NT was significantly better (and scaled the CPUs much better than Linux.
What they also found out is that NT was much worse with serving from the HD instead of the memory (maybe because they also used one big partition instead of smaller ones, which seems to slow down NTFS. The bottom line: Linux with Apache is a very suitable and fast system for real-world (mid-size) web serving needs, mainly if you have to deal with a lot of dynamic pages (like on Slashdot...), but the main findings of the Mindcraft study are true under the given test circumstances.
You say that Mozilla was no success. I also thought a bit like that before Milestone 7. If you compare M6 and M7 and have a bit of imagination how, lets say, M12 will look like, I think Mozilla is going to be THE browser. It just took some time. But So did MS Explorer. The first versions were just bad copies of Mosaic.
I agree with most of what you wrote. By the way: You are right that SuSE 6.1 ships with a very bad GNOME package. But the original GNOME SuSE packages from the GNOME homepage install without a problem and work very well. There only is a minor problem with YAST that always wants to overwrite two libs with the ones on CD, but you just have to click "cancel" to stop it from doing so during install. I think it was just a matter of "timing": When SuSE froze its distr, GNOME wasnt really ready yet.
Last year Siemens had Linux-based NCs at their CeBIT booth. They were diskless, but had a 8 or 16 MB flash memory to boot into the web AFAIK. Maybe they have some info in the web.
