Scala programming language and Venkat Subramaniam videos

Posted by jpluimers on 2015/06/30

A long while ago, someone (it was too long ago, so I sincerely forgot who, it probably was in the JBuilder era) told me that I should try out Ruby and Scala.

I did take a short look at Ruby back then, but since Ruby was so focussed on Web Development, and my heart really wasn’t there, postponed it to the times that the Web would be hot for me.

Then I should have taken a look at Scala (which compiles to Java bytecode), but since I abandoned Java (JBuilder wasn’t nice, Java programming was slow and modern IDEs like IntelliJ IDEA and Eclipse weren’t there yet).

Now that I’ve done truckloads of work in the .NET and Delphi world (including domain specific languages and Pascal based products), I bumped into these Scala videos by Venkat Subramaniam:

Boy, I should have taken a look earlier: like Delphi and C# it is a statically typed compiled language, but it is on steroids.

Yes, I know it leans on the Java bytecode as a run-time platform, but so does the Android SDK as one of the Java Platforms. Contrary Ruby, which with IronRuby runs on .NET and RubyMotion runs Mac and iOS, Scala does not run on the .NET platform any more.

Given the witty way of presenting I’m surely going to follow Venkat Subramaniam and watch some of his other videos too.

Shortly after watching the above I bumped into this video by Steve Yegge (Google): Dynamic Languages Strike Back – YouTube.

Coding Kata videos: Bowling game

Posted by jpluimers on 2015/04/22

A long and shorter while ago, I wrote about practicing your coding and test driven development skills:

Here are some Coding Kata videos of the Bowling Game Kata in various languages and environments. Some of them are dumb (no audio) just like good practice usually is. Note: it helps to know a bit about 10 Pin Bowling Scoring rules.

And since I want to learn Haskell and have done a lot of Tic-Tac-Toe demos inthe past:

CodeInspect says “Hello World”: A new Reverse-Engineering Tool for Android and Java Bytecode – via: Secure Software Engineering

Posted by jpluimers on 2015/01/29

Thanks  for mentioning this, so it got on my research list:

a new reverse-engineering framework that works on the intermediate representation Jimple and supports all the features above and a lot more.

CodeInspect supports as input format a complete Android Application Package (apk), just the Android bytecode (dex-file) or a jar-file.

In the following we will describe the different features based on a malicious Android apk.

The figure above is a screenshot of CodeInspect. As one can see, CodeInspect is based on the Eclipse RCP framework

RosettaCode: cool way to improve your coding skills

Posted by jpluimers on 2015/01/22

Wow: I feel like having lived under a stone for 8 years, as RosettaCode has been alive since it was founded in 2007 by Mike Mol.

The idea is that you solve a task and learn from that, or learn by seeing how others have solved tasks or draft tasks.

So in a sense it is similar to the Rosetta stone: it has different languages phrasing the same tasks.

There are already a whole bunch of languages on RosettaCode (of which a few are in the categories below), and you can even suggest or add your own languages.

When you want to solve tasks, be sure to look at the list unimplemented tasks by language that leads to automatic reports by language (for instance two of the languages I use most often: C# and Delphi).

I’m sure there are lots of programming chrestomathy sites, even beyond the ones, and it feels very similar to programming kata sites.

Episode 215: Gang of Four – 20 Years Later : Software Engineering Radio

Posted by jpluimers on 2014/12/23

If you are into serious software development, then this is a 75 minute PodCast you must listen to: Episode 215: Gang of Four – 20 Years Later : Software Engineering Radio.

Abstract

Johannes Thönes talks with Erich Gamma, Ralph Johnson and Richard Helm from the Gang of Four about the 20th anniversary of their book Design Patterns. They discuss the following topics: the definition of a design pattern and each guest’s favorite design pattern; the origins of the book in architecture workshops; the writing of the book together with the community; the rock-star feeling at the release of the book at OOPSLA conference; the influence of the book on the industry; the evolution of the Observer pattern; and new patterns since the book was released. The interview closes with each guest talking about their current projects.

What I liked

Of course I enjoyed the history of the Gang of Four (and am still sad that John Vlissides passed away).

Delphi Cookbook for USD 5 (or EUR 4.80); actually: get any Packt eBook or video for that price – #packt5dollar

Posted by jpluimers on 2014/12/20

Earlie this month, I wrote a review about Delphi Cookbook.

Well: as of last thursday, you can get that for USD 5 (or EUR 4.80, so better get yourself a USA account: just ensure your address is in the USA).

Heck: until januari 6th, you can get any eBook or Video on Packt for USD 5.

Note there is even an x-Mas countdown on the way (with each day a free book that is readable/downloadable for 24 hours).

There’s over 2500+ books to choose from, so I’m grabbing this chance to learn a few things on OpenCV, Scala, and PowerShell.

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.
  3. 0:37:56 ▶ The Clean Code Talks – Don’t Look For Things! – YouTube. Read the rest of this entry »

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 »
