Delphi hinting directives: deprecated, experimental, library and platform

Posted by jpluimers on 2014/10/01

I’ve been experimenting with the Delphi hinting directives lately to make it easier to migrate some libraries to newer versions of Delphi and newer platforms.

Hinting directives (deprecated, experimental, library and platform) were – like the $MESSAGE directive – added to Delphi 6.

Up to Delphi 5 you didn’t have any means to declare code obsolete. You had to find clever ways around it.

Warnings for hinting directives

When referring to identifiers marked with a hinting directive, you can get various warning messages that depend on the kind of identifier: unit, or other symbol. Read the rest of this entry »

A few must watch videos on test driven development and unit testing

Posted by jpluimers on 2014/09/25

If you are going to do test driven development and unit testing, you should watch these videos and slide decks, most of them by Miško Hevery:

  1. Not a video, but a good starter: Guide: Writing Testable Code (or read the PDF version).
  2. 0:32:07 ▶ “The Clean Code Talks — Unit Testing” – YouTube.

Registry keys to prevent Java installs from adding sponsors (Ask/Google/Yahoo Toolbar, McAfee virus, etc) via: Super User

Posted by jpluimers on 2014/06/02

One of the reasons I quit Java development a while ago is that for years, each and every Java client update on Windows wants to install “add-ons” like Ask/Google/Yahoo toolbars, McAfee viruses, etc.

Many people have complained about it, just to name a few and show an on-line petition against it:

There are many cumbersome ways around it:

Though suited for corporate installs, all of those are impractical when your friends keep calling “hey, how do I get rid of these toolbars” and you cannot control their complete install process.

Super User user Danilo Roascio made my day when wanting to get rid of that behaviour.

His registry way to prevent those installs is way easier!

It not only disables the installs of any sponsored add-on, the Java update does not even show the checkbox any more (so the install process is shorter).

This is what he answered: Read the rest of this entry »

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.

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 Go PHP
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.
