Open Source

In Shelly’s awesome post on 3D printing,he hints at a future where spare parts will live on files and not shelves. It completely upsets our notion of manufacturing, where commodities are tangible objects. Physical would become virtual. The question would then become: open-source or clo...

Concerns are raised every once in a while in the broader free and open source software community about freeloaders. The attitude expressed is that if you're getting the benefit of FOSS, you should contribute. Building a business on a FOSS project you don't own, whether you're providi...
I've recently been involved in several discussions that are variations on, "Which open source or free software license should I choose for my project?" Here is my way of looking at the large and growing collection of licenses in the wild. First let's make sure we all understand that I ...

VMware has applied to join the OpenStack Foundation, potentially giving the burgeoning open source cloud stack movement a huge dose of credibility in the enterprise. There are risks to the community in VMware’s involvement, of course, but on the balance this could be a pivotal event. T...

Responsive WordPress themes are the current craze in the open source world.  But are they a true requirement or just a bunch of hype thrown out to sell more premium themes to unsuspecting buyers?  Do WordPress users really need to consider upgrading their existing themes to one that is...
OpenStack is an open-source cloud framework for building on-demand Infrastructure as a Service. This tutorial in essence distills from this two-page set of instructions for setting up devstack on a single server primarily for use by developers. I used a DELL 1950 with 8 GB of RAM, in...

Open source platform as a service (PaaS) platforms are one of the most exciting topics in the software industry nowadays. Following the $212M acquisition of Heroku by Salesforce.com, we’ve seen how, in a matter of months, platforms like dotCloud, VMWare’s Cloud Foundry or Red Hat’s Ope...
The cloud: few topics are as frequently discussed among information technology (IT) professionals. But why? Internet hosted applications and services certainly aren’t a new concept. In fact, application service providers began delivering functionality via the Web more than a decade ago...

A few months back, in a story mostly about Microsoft’s complicated relationship with the Russian government and its seemingly dualistic role in the ongoing suppression of various free speech and human rights organizations, we also surfaced contemporaneous reports in the Russian languag...
The history of free online stuff started with the advent of the Worldwide Web. Prior to that, in the medieval Internet days, we had to pay. We paid for monthly services such as CompuServe, The Source, and AOL. We hated that. We also paid, and paid, for Microsoft products. The...

Open source software, in brief, is software that is distributed under a specific type of license. Open source licenses attempt to ensure the code is freely distributed. The vision is of large communities of developers and users who both give and get software code freely. Note that this...
Some people say “oh, you’re dual licensing like MySQL. So does that mean that I get to use it and not pay as I don’t with my MySQL based website?” Companies such as Google have thousands of MySQL servers running without paying license fees for it, due to a loophole in the GPL (in both ...
The November 2009 issue of Communications of the ACM (CACM) has a very interesting article by Paul Stachour and David Collier-Brown entitled “You Don’t Know Jack About Software Maintenance”. The authors argue energetically for using versioned data structures and “continuous upgrading” ...

There are reports that Yahoo has put Zimbra on the block. Honestly, this came as no surprise at all to us at Zoho. I remember scratching my head when the acquisition was made; I didn't see how an enterprise/business focused open source offering like Zimbra fit with Yahoo, as a technolo...
Jon has a point; Microsoft’s restricted (i.e., Express) editions are as free as the open source alternatives. This is undeniably true, since the purpose of many software vendor’s “Express” edition is to compete against open source on price. However, the difference is that with open sou...
Wow, look at me, I'm famous. Oh wait, what have I done. Are people going to follow me to the grocery store with cameras now? Probably not, unless the world turns it's attention from Jon and Kate to SAP Business One. But in our little world, this is pretty cool. Orchestra and myse...
