Keep Your Gnome Desktop Awake

These little bash snippets tell you how long in seconds before your screen locks and how to
keep your screen from going to sleep. This is for Gnome 3 in Linux.

To find the time in seconds before your screen goes to sleep:

[me@mybox ~]$ gsettings get org.gnome.desktop.session idle-delay
uint32 300

Set this setting to 0 to keep your screen from going to sleep:

[me@mybox ~]$ gsettings set org.gnome.desktop.session idle-delay 0

NOTE: Don’t set the idle-delay to 0 and leave the room for too long, because anybody has access to your logged in session.

Jenkins Snippets

Wipe out workspaces for all projects:
Thanks to Stefan Bäumler at, I made a copy right here.

import hudson.model.*
// For each project
for(item in Hudson.instance.items) {
  // check that job is not building
  if(!item.isBuilding()) {
    println("Wiping out workspace of job "
  else {
    println("Skipping job "", currently building")

Delete all builds for all projects:
We tweak the script above to delete all builds.

import hudson.model.*
// For each project
for(item in Hudson.instance.items) {
  // check that job is not building
  if(!item.isBuilding()) {
    println("Wiping out builds of job "
      item.builds.each { it.delete() }
  else {
    println("Skipping job "", currently building")

Jira Snippets

Let’s face it, when there are cool new tools to lean such as RoR and ASP .NET MVC 4, Grails, why throw away time you could spending learning these to becoming experts at Jira? We just want the answers so we can do what we need here, keep our project managers happy, and move on.

Here are some snippets for finding issues. After all, managing your issues is most important.

Find all issues created by you:

reporter = currentUser()

Find all non closed issues assigned to you and for a particular project:

(status != Closed ) AND assignee = currentUser() AND component = YourProjectName

Looks like a decent blog also.

Open Source Collection Libraries For .NET

In the Linked In .NET Developers group, someone posted a question asking about a good open source tree structure in C#. I suppose if you use a library it does shouldn’t matter what .NET language you use. I got to thinking about how little I new of various collection type libraries for .NET. I am think along the lines of stuff like Boost and STL for C++. Well, maybe not that big. Here is a couple that I got from the discussion.

C5 Generic Collection Library
MIT-style open license

Guid To Windows Clipboard Using Cygwin

Guid Generation
This will give you a guid to your Windows clipboard using Cygwin.

uuidgen | awk '{print "{" toupper($0) "}" }' | putclip

If you don’t like the newline that gets added, you can do this:

uuidgen | awk '{print "{" toupper($0) "}" }' | tr -d '\n' | putclip

Now, for Bash on Linux, maybe you can substitute xclip for putclip to get it into your X Windows clipboard. There may be some additional arguments for that also.

Change To Directory in Clipboard
This handy alias to stuff in your ~/.bashrc file allows you to change to directory in Windows clipboard. Copy path using ^C in Windows Explorer and then issue this command to switch to it at the Cygwin bash prompt.

alias cdw='cd "$(cygpath "$(getclip)")"'

Cannot Open MS Office Application From SkyDrive

Sometimes when I would open my Excel spreadsheet up on SkyDrive, I’d get a message saying that the document was open by another user and that I could only open it read-only, save as another copy, or cancel, or whatever, even when I did not have the document open at all. This would be really annoying. Sometimes I would reboot my box and the problem would be fixed. But now, try this:

1) From Task Manager, find this process: msosync.exe.
2) Right click and select End Task
3) Problem solved 🙂 – well hopefully, worked for me last time.

How To Install Subversion 1.7 on CentOS 6.3

I have done this and forgotten, done this and forgotten, too many times.

1) Import the Dag Wieers key:
rpm --import

2) Install the rpmforge repo:
rpm -Uvh

3) Install Subversion:
yum install --enablerepo=rpmforge,rpmforge-extras subversion

This just gets you the Subversion 1.7 client and svnserve server.

Free Me From Maven! – And I Need A Simple Open Source Artifact Repository!

This is a Level533 Living post, hopefully we all can continue to learn things. Maybe I’ll change my mind about things. Simply put, Maven for .NET builds ain’t good. I know, I’ave heard of the NPanday thing, but I’ve got an MS Build / Jenksins Build that uses MSBuild to build .NET projects. Then I use Ivy and Ant to publish build artifacts to a local file based repository, and then Ant and Groovy for all of the dirty work (upload files to QA web services, hashing, creating ISO’s. With Maven, I understand, you get one artifact per module, and ugh, a pom.xml you have to create for it.

I thought I’d move away from the Ivy file based repositories and on to something like Artifactory OSS (2,750 USD price tag a bit hefty for the paid version), Nexos OSS (I know, I’m cheap, didn’t check their price), and Archiva (FREE!!). Artifactory OSS looked great. Had it up and humming under Tomcat 7 and I was ready to go, but all of a sudden… After spending some time, I came to realize I could not get the revision number out of the file name for the ivy compatible layout. To do that, you need to define your own custom repository layout and that means you need Arficatory PAID VERSION. A FOOSTY for the Frog! I don’t want to have to name my .NET dlls like mydll-1.6.7.dll stuff in my build or my repo. I want the 1.6.7, or whatever version that be, out of the file name. This is a .NET project, not Java, no versions in file names. So out with Artifactory. In case your are asking, I did try to edit the Central Configuration Descriptor in Artifactory using the Advanced -> Config Descriptor tab in the gui, to know avail.

But then there’s Nexus, supports only Maven 1 and 2.

And Then there’s Archiva, suports only Maven 1 and 2.

Are there any non-Maven open source build artifact managers out there? We’ll see.
