PowerShell, Cmder / ConEmu, Posh-Git, Oh-My-Posh, Powerline Customization

Pimping Up Your PowerShell & Cmder with Posh-Git, Oh-My-Posh, & Powerline Fonts

Backstory (TLDR)

I work as a full-stack developer at work. We are a Windows & Azure shop, so we are using Windows as our development platform, hence this customization.

For my console needs, I am using Cmder which is based on ConEmu with PowerShell as my shell of choice.

Yes, yes, I know nowadays you can use the Linux subsystem on Windows 10 which allow you to run Ubuntu on Windows. If you are looking for customization of the Ubuntu bash shell, check out this article by Scott Hanselman.

A jenkins script to clean up workspaces on slaves
// find old workspace folders on any node (master/slave)
// currently only look for deleted branches of multibranch (pipeline?) jobs, and remove them
// also finds builds older than 90 days. Set flags below to true to actually do deletes

When you delete jobs in Jenkins, the corresponding workspaces in the build slaves won't be deleted automatically. This Jenkins script will go to each slave and check if the jobs are already deleted in Jenkins master and delete the workspace.

import hudson.FilePath
import jenkins.model.Jenkins
def boolean isFolder(String name) {
def item = Jenkins.instance.getItemByFullName(name)
return item instanceof Folder
}
def deleteUnusedWorkspace(FilePath root, String path) {

How to work with binary diffs / patches of Java jars

How to do binary diffs with Java jars

This is a simple example how to generate and apply a binary patch to a jar file. In the hope that some tooling vendor or gradle / maven / repository backend guru might pick this up to unban us from too long dependency download times :)

Download test jars

For testing we download two versions of the commonly used google-guava library.

$ wget http://central.maven.org/maven2/com/google/guava/guava/18.0/guava-18.0.jar

Embedding an SSH-accessible REPL in a Clojure process

N.B. This is now a library, thanks to the efforts of the wonderful @mtnygard. And the README does a good job of making clear just how terrible an idea it is to actually do this. :)

As any Clojurist knows, the REPL is an incredibly handy development tool. It can also be useful as a tool for debugging running programs. Of course, this raises the question of how to limit access to the REPL to authorized parties. With the Apache SSHD library, you can embed an SSH server in any JVM process. It takes only a little code to hook this up to a REPL, and to limit access either by public key or
