NetBeans 10 on macOS
At the moment, you can’t get nice looking, full-blown installer of NetBeans for macOS, yet. However, running it is fairly easy. Just make sure you have recent JDK installed – just get it from here: JDK 11 Note! Please, make sure you can survive with new licensing model preparred by Oracle. It’s quite different comparing […]

In case you haven’t heard about NetCAT program, yet, take a look here: NetCAT 10.0. NetCAT is a community acceptance testing initiative targeting NetBeans. If you work with NetBeans a lot, I guess this is the best place to support the team behind the product, and (as well) it’s the best place to get the […]

macOS – how to get familiar with VIM
If you have never ever worked with CLI (on macOS) I suggest to start with iTerm2: https://www.iterm2.com. I just want you to know, this is my personal view, that iTerm2 is way better comparing to default Terminal – one that you can find inside /Applications/Utilities/Terminal.app. If you have never ever worked with VIM before, I […]

Java preprocessor
If you have developed applications using C, you are probably aware of preprocessor. If you have ever worked with JNI code, you recall preprocessor’s directives for sure. You can find lots of them inside JNI based code generated through javah or javac -h. /* DO NOT EDIT THIS FILE – it is machine generated */ […]

iPod shuffle – “-Voice Over, where have you been all my life?”
Have you tried to organize your songs into play lists? And that’s what you have in your little iPod shuffle? “-All songs” “-Play list one” “-Play list two” “-Play list three” “-…” Man, this was driving me nuts.

Just dev.off!
I was playing with RStudio recently. And there was this annoying “issue” with plots. I am calling it “issue” as I am not quite sure whether this is a bug or a feature. The problem was that plots were drawn outside plot area. Axises were missing, title was too high, etc. I was trying to […]

Be careful with du
Recently, I was little bit surprised by the output of du command. It turned out that size of a directory can vary, heavily, depending on the filesystem that is used for storing files. I was examining the size of application at different locations and what struck me were the differences in size reports. # at […]

vi + which
Sometimes, you want to look at the command (where is it located), and then, you decide to actually take a look inside the file (e.g. script). Instead of copying and pasting location, do following which perl vi `!!`

You shouldn’t learn Vim for learning’s sake
I can see people around (on various blogs) saying “- I’ve never used Vim before, and it’s so cool. I really have to learn how to use Vim!”. Just Don’t. If you are using NetBeans, Visual Studio, Eclipse, keep it that way. Don’t put yourself into this illusive thinking that by starting using Vim you […]

Coding time flies when you’re having fun
Everything should be kept as simple as possible, but no simpler. Teaching kids is a hard work. By teaching I mean not lecturing, but real, efficient and full of fun explaining how things work. I still remember one of my first computer languages – LOGO. This was Atari time and we have learned principles of […]
