Perl 5.10 added a new class of variables ‘state’ that are similar to ‘my’ in scope but are only initialized once.

JDK 7 has several enhancements to the try-catch construct. Try with resources allows for ensuring that resources are closed and freed up without the need to explicitly call the close function. Any class implementing java.lang.AutoCloseable can be automatically closed without the need for a finally section in the try block. The syntax is a [...] JDK 7 adds the ability to use String objects as the case in switch blocks. It’s not exactly an earth shattering addition but I find it quite useful in avoiding long if-then chains. Plus the release docs claim that using a switch is more efficient. At the bottom of this post is a small [...] Build 147 for JDK 7 is now available with the goal of a generally available release later this month. Some good resources are: Oracle’s Java 7 wiki Java 7 project page Get the release from the download page Oracle’s Java SE 7 documentation As I test out the release I’ll do some posts on [...] As of version 5.12 perl now supports using each with arrays and hashes both.

The truth is it’s quite simple if you have a normal set of build tools installed. GCC, make, etc. I will walk through the steps here on doing the build and install. Decide where you wish to [...] This is a follow up to previous post This should be interesting … where I stated the intention of getting WordPress up and running in my SourceForge user web space . Depending on where you are reading this you can see that it worked out pretty nice. I’ll go over what steps were needed. [...] We’re still a bit undecided on whether to use the library website to post items intended only to the dev team. For now dev items will be posted on my SourceForge site and at Poor’s site both. Poor and I have tried to structure the build process to minimize special requirements on any [...] Can you really run a functioning WordPress blog on Source Forge’s user space? We’re going to find out. My first thought about installing was admittedly ‘this is going to hurt!’. Once setup it will be accessible at Rog’s SF Notes <edit>The install went well. You can read about it at the follow up post [...] |
