Thepoles in a tensegrity-tower seem to float in air.Although they might look confusing, these structuresare really very simple. All you need is to be verymethodical when building them.It is an architectural principle for sky-high buildingand an example for SW engineering!(C) Albert Mietus *BSD, het echt vrije OpenSource OS. An non-technical overview of free, open & gratis software. And why you should consider them to use in your product. Instead of Linux!

Linux sells Sometimes BSD inside But: Linux outside (meaning: open source) Hire people?(C) Albert Mietus Other people will respond! Linux gives more responds; many wanabees 9. Linux versus *BSD (2)9 Concept, Philosophy Kernel versus complete OS Linux is a kernel only; with GNU/ Mijn missie:OpenSource tools Software Beter Maken Product, Proces, Imago Many distros versus well organized There is no common Linux OS! An non-technical overview of free, open & BSD variants share common grounds; differ in goal consider them to use in your product. *BSD, het echt vrije OpenSource OS. gratis software. And why you should BSD has 15+ years of version control, for everything!Linux-World 2009 History: Instead of Linux! BSD: Unix background, experience people Cheap PC [it started with 386BSD] Engineering background Linux: PC background; young people(C) Albert Mietus Study to MMU capabilities [again: i386] Driven by enthusiasm (mainly) 10. Linux versus *BSD (3) 10 Copyright GNU GPL versus BSD GPL(2) is more a statement then a copyright BSD-copyright is more clear (for lawyers) Software Beter Maken Mijn missie: No need/risk to give your IP away!

(this is the nice one:-) 12. *BSD, the true free OpenSource OS 12Conclusions *BSD is less known But heavily used by big expert-companies Did I mention hosting, mail, ? Software Beter Maken Mijn missie: *BSD is also Unix, *BSD is also OpenSource, Product, Proces, Imago Linux is very similar to *BSD (Techno-historical correct) *BSD is sound engineered An non-technical overview of free, open & Better then Linux. But Im biased consider them to use in your product. *BSD, het echt vrije OpenSource OS. gratis software.
