IntelliJ IDEA: Have you tried Search Everywhere yet?

The Search Everywhere action, invoked with double Shift key press, was added in IntelliJ IDEA version 13. I guess, most of the IDEA users/fans know about this feature and are enjoying it. At first glance, it just provides the means for search. You can search "everything": classes, files, symbols, actions, settings, etc. However, Search Everywhere widget is full of easter eggs.

Try using to jump between the search result groups. Or try left arrow to navigate in the history of search entries. But also, depending on the nature of the item that was found, the widget can provide some extra actions, like in the screenshot below: the "Show Navigation Bar" entry has an extra switch - on/off - showing that you can actually invoke this action.

Search Everywhere is a little gem in IntelliJ IDEA and all its features are yet to be discovered ;)

RebelLabs: Java Tools and Technologies Landscape for 2014

A great report on Java Tools and Technologies, aka JavaTnT :), was published just recently. As usual, one may say that those is a "biased" numbers. Well, the numbers might be biased. But it is not really clear, the bias agains/towards what?

There are discussions at Reddit and Hackernews about the report. Some would say that the numbers are legit. Some would say that the numbers do not make sense. Of course, the numbers do not make sense if you don't like them ;)

In any case, the results present the JavaTnT landscape pretty well. It would be nice if more people would care to enter their data during the survey instead of arguing about the numbers afterwards. Oh well.. first world problems :)

Mbed

At DevNation event I picked a very nice device - Mbed NXP LPC1768 and a Xively development board. It is surprisingly easy to program: you don't have to install any software on your own computer - just log in at mbed.org website, they provide a web-based IDE. The compiled program can be downloaded directly into the host device via USB (just like if it was a flash drive). When the device is reset, the latest binary is picked by the system and executed. Embedded programming have never been easier! :)

DevNation 2014: post factum

DevNation was fun. It would have been even more fun it it wasn't co-located with Red Hat Summit. It basically fell into the same trap as JavaOne with Oracle Open World - being just a side event of the "real" conference.
The schedule was actually awesome but lots of talks didn't receive the attention they deserved due to the dispersed focus and many parallel tracks. The event really has a great potential to become the next big even for Java (and not only Java). There are quite a few videos available from the talks. Here are some interesting ones:

Neal Ford - Opening Keynote: Agile Architecture and Design.

Jason Greene - JVM Finalize Pitfalls: How to Avoid the Danger

 The positive side of DevNation event is definitely the location. I love San Francisco - very nice city!

Java 8 Lambdas - The Unintentional Puzzle

I was tinkering with Java 8 lambdas just lately. It happened to be an early morning on a bus from Tallinn to Tartu and I probably didn't sleep enough the night before. So I managed to puzzle myself with this little piece of code:

I actually expected it to print "Hello, lambda!" when executed, but it didn't. Can you figure out why? This is a very simple puzzler, and a very silly mistake that I did. I shouldn't have used the method reference to initialize the runner variable of RunForrestRun class. However, while the example is very simple, it actually shows that the new features do bring some accidental complexity into the language.

IntelliJ IDEA for Eclipse users

Finally! With help from the awesome RebelLabs team, I present you the Getting Started with IntelliJ IDEA as an Eclipse User report.

If you're an Eclipse user and considering to give IntelliJ IDEA a try - this is the finest read for you! If you're a convinced Eclipse (or NetBeans) user and not considering to switch to IntelliJ IDEA, still, you might learn something interesting from this report. If you are an IntelliJ IDEA fan, yet, you can find something interesting from this read.
