In this pretty short introduction I am going to describe you a trick which I learned recently while doing new CI/CD configuration for one of open source projects I work with.

Wireshark is outstanding piece of software. I had few chances to make use of it, early in my IT days, then in one of bigger projects I worked on, and finally now - when I began working on industrial integration protocols.{{ double-space-with-newline }}This blog post will describe a journey I had with Wireshark over last couple of weeks and tell you why clicking couple of times everywhere you CAN is sometimes better.

Over past couple of months I’ve been playing with gitlab ci as it brings a bit of refreshing breeze after years of struggle with Jenkins. Don’t get me wrong, I value what Jenkins did for us over past decade. I just think that maintenance of it is a bit of nightmare. Yet, I’ve reached a place where I had to adjust some more stuff for gitlab in order to get my builds straight.

I’ve been looking for some ways to use Mockito to with builder pattern using fluent calls. There are couple of articles online, however none of these addressed my case, a builder which receives calls and returns fully working object after a final ‘‘build’’ call without the need for further setup.

It is already 12 months since I started using my (first since very long time) desktop PC. In my previous blog post I’ve described reasons why I decided to resign from Apple hardware. In this one I will tell you how I managed to drop OSX and its ecosystem with minor pains. I feel that I owe you also some insights - which applications I had to swap and which I was lucky to keep. Because I work with Java on daily basis I do not have any major troubles with portability of my software, however just few out many programs is actually written in Java. ...

I must start from small confession. I am not an computer kido. My first computer was AMD K6 with 266 Hz clock I got for Christmas back in 1999. I’ve seen in my life Amiga, but I wasn’t part of long standing battle between platforms. I’ve seen Norton Commander on my friend PC who got his Pentium in 95, but I never had to run such tool on my own. Point of bringing whole history of myself coming to computers is to show you that I am relatively fresh to it.

One of most important things, if not the most important in software, is release process. There are whole books written about “shipping software” and software release is one of key parts which needs to happen in order to deliver our programs to end users. In this very short post I will give you a short tip about how to do a test drive of a release which is not published yet. One of main principles of maven central is “what goes there, stays there”, meaning that anything which becomes public will stay public. For that reason we, as software developers, want to deploy things which are free of any major issues at release time. Staged release is one of things which are supported by maven-release-plugin. Overall idea behind this is to let people have a test drive before deploying artifacts to public repositories from which they can not be removed. Of course this might be seen as completely unnecessary step if you release a small library, but could be extremely useful for bigger projects, avoiding something I would call a quick fix hiccup. ...

Apache Felix Configuration Admin (CM) is widely used component which is responsible for provisioning of one of most common OSGi services. Main responsibility of it is to bring configurations stored in property files to services. While digging into Felix CM code I have found that it is able to create scalar values of certain type ie. Long, but also more complex structures such Array or Vector. The biggest issue was that I couldn’t find any way to force it to create array from string representation. Thanks to google ( FELIX-4431 found on 4th page of results) and debugger goodnes I finally managed to do it. Here is recipe how to proceed. ...

I use Eclipse since years. Some of you may say that I’m a masochist. Well, people have different preferences. :-) I prefer Eclipse over other editors. What’s the pain? Eclipse had same look and feel since years. I used to have the same appearance under Windows/Linux/OSX. Everything was the same except fonts. I was very unhappy with default Juno look and feel which looks like few widgets deployed in browser. Even web-based IDEs looks better than Juno! There was some posts about that and some solutions. However nobody told how to get older look and feel in place. ...

Piątego lutego miałem niekłamaną przyjemność podziwiać Jacka Laskowskiego prezentującego temat Praktyczne wprowadzenie do OSGi i Enterprise OSGi. Link do filmiku z prezentacją Jacka znajdziecie na Jego blogu. Tymczasem, poniżej wideo z Karafem. :-)
