When Jim Whitehurst set out to write his book The Open Organization: Igniting Passion and Performance, he wasn't looking to define the open-source movement in the same way that Eric Raymond's The Cathedral and the Bazaar defined open-source. Rather than define open-source as a development methodology, Whitehurst's focus is on open-source principles as applied to the domain of company management.In a video interview, Whitehurst details what the motivation for the book is about, and why there won't be a new theory of management anytime soon.

Monday 29th of June 2015 05:14:24 PM
often find myself needing to run the same command on many boxes at the same time. For example, I’ll sometimes need to check the memory usage of a fleet of boxes. Other times, I’ll want to quickly grep the logs of multiple machines, for troubleshooting purposes. Once you grow beyond managing one or two servers, you’ll find yourself wasting a ton of time if you don’t have a way to run commands on multiple Linux computers simultaneously. In this post, I’ll explain how to quickly run commands on large numbers of Linux machines at once.

The job is not done until the documentation is complete

Monday 29th of June 2015 04:17:13 PM
Which came first, the program or the documentation? Therein lies the dilemma.I don't think I have ever heard anyone say, "This documentation is great." Mostly I hear how badly some specific documentation sucks, and I have repeated that refrain myself many times.And yet there is a lot of really good documentation out there. For example, the documentation for LibreOffice is excellent. It includes several documents in multiple formats including HTML and PDF that range from "Getting Started" to a very complete user's guide for each of the LibreOffice applications.read more

  • Key Question: Is Bundling Proper?
    In both cases, bundling is either a restraint of trade or simply a wasted motion. You don’t paint a house green only to paint it red if you have any sense. The right way to do IT is to make your choice and buy/acquire what you need to accomplish your goals in the most efficient manner possible. Bundling exclusively That Other OS with all PCs was only good for an illegal monopolist and its “partners” in crime. This is not about denying businesses profits. It’s about competition in the market and freedom for users/buyers to have choice.

    Last month I started to track all the small Debian-related things that I do. My initial motivation was to be concious about how often I spend short periods of time working on Debian. Sometimes it’s during lunch breaks, weekends, first thing in the morning before regular work, after I am done for the day with regular work, or even during regular work, since I do have the chance of doing Debian work as part of my regular work occasionally. Now that I have this information, I need to do something with it. So this is probably the first of monthly updates I will post about my Debian work. Hopefully it won’t be the last.

Slowly spreading its wings into the business world, Google is venturing into arenas where Microsoft once reigned supreme. While the competition doesn't concern us much, but what has happened, in effect, is that the rivalry is bringing out the best in both companies.
