BSD license vs GPL license

Every so many weeks you find that GPL license advocates attack the BSD license. These attacks are about freedom of sharing the code, and to what degree this should be allowed.

Chemisor, a BSD advocate, is of the opinion that a linguistic misunderstanding may be the root of the disagreements over the difference licensing philosophies. He publishes his thoughts on the quite-hostile-towards-BSD Slashdot.com. Quite courageous of him! Not unexpectedly this is the start of quite a lively discussion.

The first disagreement I wish to address concerns the statement “BSD projects are free, but GPL projects stay free.” GPL advocates cannot understand why the BSD advocates are not getting this point, and BSD advocates make accusations of Communism, which are then argued to death by both parties. The problem with the statement above is the different interpretation of the word “project.” I, and I suspect many other BSD advocates, generally separate the concept of “project” from “code.” While code is what projects are made of, I do not see it as valuable as the useful product a project provides. When I write a program, be it a site scraper, or a todo program, or a UI framework, I think of my project as the entity that matters. The fact that I may have copied some code from one to another is of no concern to me.

A GPL advocate sees an entirely different situation. To him, it is the code that comes first, and the applications built from that code are a secondary consideration. Even a single line of code is precious, whether it contains a complex spline formula or i += 2;. As an aside, I would expect this mindset to be more prone to reusing other people’s code instead of reimplementing it. Where I would scoff at a piece of code, call it utter garbage, and rewrite the damn thing from scratch, a GPL advocate would probably wrap the garbage in another API that he finds more palatable. In my opinion, this leads to bloat from wrappers, instability from the garbage that is still there, and loss of skills. What programmer from the current generation is up to the challenge of reimplementing libjpeg? But, I digress. I am here to explain, not bash, so please excuse this little rant.

Installing A FreeBSD 7.0 DNS Server With BIND

This tutorial shows how to set up a FreeBSD based server that offers DNS services. This tutorial is written for the 64-bit version of FreeBSD, but should apply to the 32-bit version.

I want to say first that this is not the only way of setting up such a system. There are many ways of achieving this goal but this is the way I take. I do not issue any guarantee that this will work for you!

ezjail – A jail administration framework

I want to set up some jails. They will each be very similar. They will each be used to test a slightly different configuration of Bacula. My tool of choice is ezjail, available in the ports tree.

With ezjail, I can:

  • create a jail flavour, upon which the creation of other jails can be based
  • centrally update the jail’s ports tree

Content

Apart from helping me financially by donating you can also help me make this website the best FreeBSD website (well, after FreeBSD.org, naturally) by letting me know about news products, services or releases, or you can even provide content.

If you know of anything interesting happening in “FreeBSD Land” that I have not written about, please let me know and I’ll put it up here. Alternatively if you want to do a guest post advocating and promoting (the use of) FreeBSD (at home or at work), drop me a line.

Does your company create BSD related products (hardware etc) or offer BSD related services (hosting, software) that you want attention drawn too or promote (just like I’ve done for RootBSD), let me know.

Summarising, this blog is all about promoting FreeBSD, and you can help me with this by

Ads and donations

You will probably have noticed that I’ve put Google ads on the website in an attempt to recoup some of the costs associated with running this website.  As I don’t have the time to configure / administer a web server myself and I don’t trust my broadband connection to be 100% reliable, this FreeBSD News blog is hosted by a commercial web hosting site, which is costing money, obviously.

I don’t plan to get rich from the ads, but rather, I wish to break even. However, in case I receive enough financial support from ads and/or donations to cover the he costs associated with running this website, I am going to

  • remove the Google ads from my site, and
  • offer additional services. One of the extra services I’m planning to set up is a free CD/DVD request service. Readers with a slow internet connection or a capped bandwidth account can request from me a CD or DVD of FreeBSD or any FreeBSD based operating systems FREE of charge.

Please add your comments below about the ads. Do you object to them in principle, do you ignore them or do you think they’re complimenting the contents?

Do you like this website and do you want to see it grow and expand? Please consider making a donation.

Wanted: SpreadFreeBSD.org community leaders

SpreadFreeBSD.org has been around for a couple of months now. So far I’ve added most of the content together with Matt Olander from iXsystems.

However, now the site gets more and more visitors, we’re looking for community leaders, forum admins and content providers to make this site a little bit more interactive where BSD lovers can “meet” and find out more about BSD operating systems.

If you’re interested in helping us, please get either in touch with myself of Matt Olander (matt at ixsystems dot com).

Many thanks in advance.

Status update for KDE4 on FreeBSD & PC-BSD

KDE4.1 on FreeBSD

Click to magnify

There’s been quite a bit of noise recently about the usefulnes of KDE4, its inferiority compared to 3.5, and some are even suggesting to fork KDE4. However, Martin Wilke is in the meanwhile doing a great job porting KDE4 to FreeBSD.

Read the latest status update about the progress (incl screenshots).

Kris Moore from the PC-BSD project is now assisting with the porting of KDE4 to FreeBSD. Alpha versions of PC-BSD7 with KDE4 can be downloaded here. Please help us with the testing, and remember this is still so called alpha quality.

Flaws found in BSD, Linux software updaters

Though Linux and the BSD are considered to be very safe and secure operating systems, they are the products of human beings and hence not perfect:

The software update mechanisms used by most BSD and Linux operating systems can be tricked into installing buggy or known-to-be-compromised software on users’ systems, creating serious security risks, according to new research.

The study Package Management Security, to be published in a forthcoming issue of the university of Arizona Tech Report, analysed 10 package managers and found that all were vulnerable to exploits, allowing attackers to install unsafe software on target systems.

Package managers are designed to automatically keep software up-to-date and thus safe from known vulnerabilities. The packages analysed in the study were APT, APT-RPM, Pacman, portage, Ports, Slaktool, Stork, Urpmi, Yast and YUM.

Securing FreeBSD’s update system could be a nice project for which funding could be requested. The FreeBSD Foundation is now requesting project proposals to improve FreeBSD. If there’s anybody out there with ideas on building in better security measures read on:

The FreeBSD Foundation is pleased to announce we are soliciting the submission of proposals for work relating to any of the major subsystems or infrastructure within the FreeBSD operating system.  A budget of $80,000 was allocated for 2008 to fund multiple development projects.

Proposals will be evaluated based on desirability, technical merit and cost-effectiveness.
