In my original post I was more concerned with the overheads companies could save rather than the cost of remote working <em>per se</em>. What you are looking for is the differences between travelling to work compared to working from home or a local office. Car travel being the major one. Remote workers still use some energy to heat, light and power equipment but in most cases I suggest they will be heating homes anyway and the power requirements for the computer and lighting are certainly no more in a domestic environment compared to central office.

]]> Comment on Labels versus Baselines by Dave Foster http://blog.principia-it.co.uk/2010/01/07/labels-versus-baselines/#comment-90 Dave Foster Mon, 01 Feb 2010 23:16:02 +0000 http://blog.principia-it.co.uk/?p=235#comment-90 I would add that even though labels are at a simpler functional level than baselines, labels can be used in the same manner. That is, most tools that provide the label function, give the CM user a way to access all CIs that have a specific label (i.e., a baseline) for reporting or building purposes. I used this extensively with PVCS Version Manager and passed several audits successfully. Further, I have used the baseline functionality provided by Serena Dimensions CM with the equivalent success. Given the opportunity to choose between the two, I prefer using labels because of the flexibility. Thanks for your articles. Regards.

Obviously this not always easy to do, however, it keeps everything in line. Compatibility issues are of course the hardest to overcome. I do like how you bring up the need to keep in mind for expanding your system externally. Many organization fail to plan for that eventuality, which creates a disaster when the time comes.

]]> Comment on Creating Tags in Subversion by Mark Bools http://blog.principia-it.co.uk/2009/12/04/creating-tags-in-subversion/#comment-79 Mark Bools Tue, 05 Jan 2010 11:18:45 +0000 http://blog.principia-it.co.uk/?p=414#comment-79 Thanks Greg. Your points are well made. The new 1.6 relative URLs are a massive help doing this sort of thing. This brief post was, of course incomplete, for a more complete treatment of tagging check out my training course http://principia-it.co.uk/training/subversion (you're not the only one who can self promote :D ). While we're on the subject, I would encourage people to join the WANDisco Subversion effort (http://subversion.wandisco.com) it's only just starting but is shaping up nicely as a focus for Subversion related information.

I'm not used to create tags this way, so thank you for the tip. A few things that your blog entry is missing in order to be complete: - Tags = Branches = directories. That's an important thing that most subversion user don't know about. There is absolutly no magic behind tags and branches. - it should be told that selective tags can be created directly into subversion which avoid the "cost" of having a working copy in order to create tags. EG this is perfectly valid: svn copy --revision 4 http://subversion/myrepo/trunk/dir3 http://subversion/myrepo/tags/mynewtag/dir3 (provided that mynewtag folder already exists). - One really usefull feature of subversion 1.6 which is particularly convenient when creating tags is the relative urls thing. Provided that you are located in a Working Copy, it let you write something like this: svn copy ^/trunk ^/tags/release-1.0 -m "Tagging for release 1.0" You can find more about relatives urls in subversion here: http://subversion.wandisco.com/component/content/article/1/20.html (a bit of self-promotion ;-)). cheers.
