TurnKey Linux Virtual Appliance Library


I used bash for a decade or so before I discovered this little highly useful gem a few years back. Nowadays I can't remember what I used to do without it.

From the bash manual page:


The search path for the cd command.  This is  a  colon-separated
list of directories in which the shell looks for destination
directories specified by the cd command.

A sample value is ".:~:/usr".

I've added the following to my .bashrc:


Now this works:

Bug hunting with the scientific method

I've never come across a problem I couldn't solve using the following technique / problem solving methodology, and I've come across some tough ones.


Just say no to multi-tasking: reflections on productivity

Tafasta merubhe, lo tafasta.
תפסת מרובה לא תפסת

- Ancient Hebrew proverb from the Talmud (Translation: Try to catch too much, catch nothing.)

I had an unsatisfying couple of days that got me thinking what I was doing wrong.

In retrospect, I realized I was jumping all over the place, trying to keep too many balls in the air. I was investigating the rsync algorithm, while trying to fix a TurnKey build problem, while researching distributed filesystems, etc.

This is problematic for two main reasons:

Trouble writing? You probably aren't scaffolding enough

Having trouble writing? It may be just that you are having trouble doing two things at the same time:

  1. decide what the prose should say (substance)
  2. write the prose (form)

They are intimately interconnected. If you don't REALLY know what you want to say, you are going to have a hell of a time saying it. And then instead of actually writing sentences, you play with grammer and use alot of syntatic sugar until your sentence seems to have filled a respectable space (form over substance) and you can move on to the next one.

In retrospect, I tend to underestimate a lot of things. I underestimate challenges. I underestimate my own limits. I underestimate authority. I routinely underestimate how difficult something is going to be to accomplish.

Git tip: how to merge multiple projects into one big repository

A while back I decided it would be a good idea to combine a loose collection of related Git repositories into one big Git repository.

The rational for this was that I noticed that often the same logical change had to be broken up into multiple commits across these previously separate repositories in a way that made it difficult to track which changes were part of the same change. In other words it artificially fragmented the commits and made revisions harder to track.

Pride and prejudice: falling in love with your own bad ideas

Opinion, often hasty, can incline to the wrong side, and then affection for one's own opinion binds, confines the mind

- The Divine Comedy

Sometimes I have bad ideas. Happens to the best of us. If I try to avoid them my mind freezes up. So I just let the ideas flow. No filters. Sure, most of them are crap, but every once in a while a gem of a good idea passes through.

v14.0 stable release - Massive Community Effort!

Drum roll please... May I proudly introduce: The TurnKey Linux v14.0 release!

A long time coming...

Wow is it mid September already!? What has happened to the year?!

Marching towards v14.0 RC2

As anyone who has been paying attention would realise; v14.0RC1 has been out for over a month now. And here at TurnKey central we have been very busy updating the appliances. To be honest I wish that I was announcing the final release, but alas we're not there yet - there's still lots of work to do...

How to build a TurnKey appliance ISO from source

For the upcoming v14.0 stable release, we are doing things a little differently than we have before. Historically new releases have been done totally in house with help from the community. This time around we have some QA testers (kindly donated by a TurnKey user; more about him in another blog post...) who are going to help out and make sure that our appliances are as good as they can be for the v14.0 release.
