JavaScript is not Java – A humorous comparison of JavaScript and Java.
Posted by jpluimers on 2016/06/23
Recently I did my very first JavaScript in HTML development. Since it was a one page experiment, I didn’t want to put it in an official repository of it’s own…
which reminded me of JavaScript is not Java – A humorous comparison of JavaScript and Java.
And still lots of uneducated people think they are the same, for instance the NBC Chicago publishes this at the start of the year:
Java Developer; What they do: Program websites using JavaScript.
They fixed it later but then the harm was already done (besides making a lot of fun of themselves and others making fun out of them too):
Java Developer; What they do: Write programs used by mobile devices, websites and mainframes.

Registry trick now fails to work for the Yahoo Search Engine update in Java 8 – was: Registry keys to prevent Java installs from adding sponsors (Ask/Google/Yahoo Toolbar, McAfee virus, etc) via: Super User
Posted by jpluimers on 2016/01/20
Anyone who knows a trick to prevent Java 8 from installing the Yahoo search/toolbar in Chrome and Internet Explorer?
This trick used to work in the past, but fails as of Java 8:

Jon Skeet’s speech “Back to basics” is really a good watch – via Jørn Einar Angeltveit G+
Posted by jpluimers on 2015/07/15
Thanks [Wayback] Jørn Einar Angeltveit for sharing this a while ago:
A session by Jon Skeet and Tony the Pony (which has strong teeth) presented during the Polish DevDay 2013 in Kraków, Poland.
[Wayback] +Jon Skeet’s speech [Wayback] “Back to basics” is really a good watch.
In a funny way, he explains why the simplest fundamentals of computer software text, dates and numbers can cause some real headache for the programmer…
In case you didn’t know: Jon Skeet is “Chuck Norris” on [Wayback] stackoverflow.com:
The subtitle is “the mess we’ve made of our fundamental data types”.
Some of the topics covered:

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:
- Cyber-Dojo: practice unit-tested programming in pairs/groups using Katas.
- RosettaCode: cool way to improve your coding 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.
- Bowling Game – Ruby – YouTube.
- Bowling Game – Python – YouTube.
- Bowling Game – Java – YouTube.
- [TDD] Bowling Game Kata – YouTube (also Java).
- Bowling Game – C# – YouTube.
- Bowling game kata in Delphi and DUnit TDD – YouTube.
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 Kristian Köhntopp 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).
