Subversion is impressive in it's design goals and from the outset, it's goals and objectives appear to be very well thought out. Subversion is flexible and repositories can be made available in many flexible ways from as simple as a repository on your local hard drive to internet based repositories served over http or https protocols.

For this exercise we show how to set up a simple repository on a network server with secure shell access. The requirements of the repository are accessibility by a small stable development team of 3 trusted inhouse developers with a need to update and commit remotely outside of the local area network. The requirement for tunneling repository traffic over ssh is simply to protect the small amounts of sensitive data such as API pins or private SSL keys that are shared by the repository. Also keep in mind that there are many, many ways to set up a Subversion infrastructure. This is just one way that suits my needs and is based on the concept explained in the Subversion book in the section SSH configuration tricks . There are other ways and variations that may suit your needs better.

What would you like to do with those references?" and three choices: Ignore, Cancel and Unbind.

The key is deleted BEFORE that message is displayed! .... and clicking on any of the buttons has no additional effect. Specifically Cancel does NOT cancel! and Unbind does NOT unbind. In any case the key should not be deleted until AFTER a choice of Ignore or Unbind is selected. ]]> Thu, 11 May 2006 10:05:58 -0400 http://homepage.mac.com/kelleherk/iblog/C1367868047/E20060511100558/index.html http://homepage.mac.com/kelleherk/iblog/C1901548470/E20060504082322/index.html I needed to use tcpflow the other day for the first time since I got my Intel Macbook Pro running Tiger. I downloaded and installed Marc Liyanage's Panther installer sicne no Tiger installer available. I figured it might work, but it did not. I really needed to use this excellent tool, so after a quick Google search, I came across the tcpflow port in DarwinPorts. Now I was familiar with DarwinPorts, but had never looked at it in detail or installed it. So, after understanding it a little, I just installed it and then used it to install (download, fetch, make, build, install, etc) in one easy command. This was a really simple, smooth and pleasant experience..... ]]> Thu, 04 May 2006 08:23:22 -0400 http://homepage.mac.com/kelleherk/iblog/C1901548470/E20060504082322/index.html http://homepage.mac.com/kelleherk/iblog/C1216817469/E20060427090217/index.html Pierce T Wetter shared a nice trick on global page direct actions with url query parameters.

"Problem: Some browsers trigger the WOForm action, whilst other trigger the first submit button action when a user hits the enter key. I've tested my test app with IE v4+, Netscape v6+, Opera and Chimera on both mac and windows and can confirm that it is a browser related issue.

After much playing about with this issue, i have decided that the best way to get the behaviour i required was to add a 1x1 pixel image as an WOImageButton at the very top of my form and bind it's action to the action that I want to trigger if the user hits the enter key, and leave the form action method unbound (thanks to Pierre Bernard for this tip). This provides consistent behaviour across all browsers mentioned above. Note that i also add an extra tag to the WOImagButton of TABINDEX="" - this means that as the user tabs through the form elements it doesn't pick up on the single pixel image and hence it is completely invisible to the user." ]]> Tue, 25 Apr 2006 08:51:22 -0400 http://homepage.mac.com/kelleherk/iblog/C1133025376/E20060425085122/index.html
