Choose your chart type & Amount of profanity in git commit messages per programming language (via: andrewvos.com)
Posted by jpluimers on 2014/03/07
Funny charts at andrewvos.com – Amount of profanity in git commit messages per programming language.
The source is online too: AndrewVos/github-statistics.
And it led me to this really nice way of choosing your chart type.

Remote Android screen monitoring and viewing
Posted by jpluimers on 2013/11/25
Another one in the “WordPress Missed schedule” series.
Below are the Android remote screen monitoring/viewer/mirror tools I know about:
- For a long time, I have used Droid@Screen: an Open Source, Java based mature cross platform tool that uses ADB (it can even restart it for you in case it hangs) with lots of features (zooming, no temporary files, device recognition, disabling emulator devices, etc). There are some Screen Shots | Droid@Screen.
- A while ago, I saw android-screen-monitor – Android Screen Monitor – Google Project Hosting. It is a mixed Java/C++ solution that only works on Windows.
- Recently, Jim McKeeth open sources his Android Screen View: Android Screen View | The Podcast at Delphi.org. It is written as a quick hack in Delphi XE5, so right now it has less features and works in a more crude way than the two Java based tools, but it shows the potential of doing similar things with Delphi.
I primarily use Droid@Screen as so far it works best for me.
But I keep a close eye on the other two just to make sure I don’t miss improvements.

Cyber-Dojo: practice unit-tested programming in pairs/groups using Katas
Posted by jpluimers on 2013/11/07
Wow, I’ve been living under a stone (:
Just discovered the online Cyber-Dojo by Jon Jagger. It is an online manifestation of a Coding Dojo. Both have been there for years, and I think both are brilliant.
They take the concept of a Dojo as being a place to practice sports like martial arts in a pair or group setting with a series of Katas or practices.
Katas in a Dojo are a means for performing deliberate practice in order to learn new things. For instance, acquire new movement techniques, learn about your balance, gain strength, all in both a physical and mental way.
-
A Coding Dojo takes this concept into the programming world focussing at learning new programming skills. Watch the How do you put on a coding dojo event? – YouTube
-
The Cyber Dojo goes a step further and brings it on-line (a 2010 example video is Roman Numerals Coding Kata in Ruby using CyberDojo website on Vimeo).It is easy to get started: either join an existing Dojo by entering the practice ID, or setup a new Dojo where you get a practice ID that others can join.
The aim of both is do more deliberate practice.
When performing Coding and Cyber Dojo, you should use Test Driven Development using pair programming and BabySteps. Those help you to slow down, as one of the Dojo Principles is for Katas to slow down. It reminds me of the “if you are in a hurry, sit down” mantra and is a key part of the Coding/Cyber Dojo Principles too.
The aim is to learn, and part of that is to first un-learn and open you to new thoughts. That’s why it is so cool that the Cyber-Dojo provides you with:
- a bunch of pre configured programming languages*,
- preformulated practices** (including a few cyber-dojo refactorings),
- a small boilter plate to get started.
You’d think they speed you up, but that is not their aim. Like a regular Dojo it gives you an pre-set environment and gives you piece of mind to get started.
The Cyber Dojo does without a Sensei, whose purpose in a Coding Dojo is to ask questions in order to guide the participants.
That’s why it is good to use the Cyber Dojo as part of a Coding Dojo: basically the Cyber Dojo provides a standardizes set of tools to quickly setup a Coding Dojo.
Cyber Dojo languages
(a prime number, so the table is a bit distorted)

| C# | Haskell | Perl |
| C++ | Java-Approval | Python |
| Clojure | Java-Cucumber | Ruby |
| CoffeeScript | Java-JUnit | Ruby-Rspec |
| Erlang | Javascript |
Cyber Dojo practices
Many of the practices come from rosettacode.org.

in light of the zero-day Java exploits: JRE removal/install tool JavaRa from SingularLabs
Posted by jpluimers on 2013/01/17
Even though the JavaRa tool is Windows-only, it is a tremendous help scraping old vulnerable versions of the Java Runtime Environment (JRE) from your systems and keeping only the fixed versions.
Regular JRE installs from Oracle/Sun will keep the old-and-vulnerable JRE versions.
(note that it seems the recent JRE update did not actually fix the vulnerability, just the exploit, and that a new Java vulnerability might already be exploited. Be sure to keep a watch upcoming Java updates for these).
JavaRa is an effective way to deploy, update and remove the Java Runtime Environment (JRE). Its most significant feature is the JRE Removal tool; which forcibly deletes files, directories and registry keys associated with the JRE. This can assist in repairing or removing Java when other methods fail.

Forcing Java Update on Windows
Posted by jpluimers on 2013/01/04
Sometimes the Java Update checker crashes in the middle of something.
The long solution to restart it is to logoff/logon or reboot/logon and wait for it to come up.
The short solution is to manually restart it (you probably need to be Administrator to do this though) using either of these commands:
"%CommonProgramFiles%\Java\jucheck.exe" -auto
"%CommonProgramFiles%\Java\Java Update\jucheck.exe" -auto
"%CommonProgramFiles(x86)%\Java\jucheck.exe" -auto
"%CommonProgramFiles(x86)%\Java\Java Update\jucheck.exe" -auto
To keep it simple: The exact command depends (:
- if you run on an x86 machine or not, or – on an x64 machine – which of the Java versions (x86 or x64) you have installed
- if the
jucheck.exeis in theJavadirectory itself, or in aJava Updatedirectory

C#: any c# – .NET Enumeration allows comma in the last field – Stack Overflow
Posted by jpluimers on 2012/12/06
Thanks Nick Craver for answering this on StackOverflow.
Array initializers can be specified in field declarations (§17.4), local variable declarations (§15.5.1), and
array creation expressions (§14.5.10.2).
The array initializer can end in a comma, which makes some things way easier (boy, I wish I had this in other programming languages).
From Nick’s answer:
It has no special meaning, just the way the compiler works, it’s mainly for this reason:
[FlagsAttribute]
public enum DependencyPropertyOptions : byte
{
Default = 1,
ReadOnly = 2,
Optional = 4,
DelegateProperty = 32,
Metadata = 8,
NonSerialized = 16,
//EnumPropertyIWantToCommentOutEasily = 32
}
[/language]By comment request: This info comes straight out of the ECMA C# Specification (Page 363/Section 19.7)“Like Standard C++, C# allows a trailing comma at the end of an array-initializer. This syntax provides flexibility in adding or deleting members from such a list, and simplifies machine generation of such lists.”
