Volatile and atomic variables are an important feature in Java language. Especially when dealing with multi threading . A simple incrementation algorithm works fine in a single threaded program, but won’t work as expected in a multi threaded system: private int counter = 0; public int increment(int i) { return i++; } This code will work correctly in a single threaded program, but will give incorrect results in case of a multi threaded ..

The headline of Postgres 9.5 is undoubtedly: Insert… on conflict do nothing/update or more commonly known as Upsert or Merge. This removes one of the last remaining features which other databases had over Postgres. Sure we’ll take a look at it, but first let’s browse through some of the other features you can look forward to when Postgres 9.5 lands: Grouping sets, cube, rollup Pivoting in Postgres has sort of been possible as has ....

I’ve been wanting to write this for a long time, just to clarify my thoughts on the subject. Now, on vacations, I took a couple of days and finally did it. This is a personal opinion based on my personal experience and tons of books I have read, and I am not, by any means, the supreme holder of the truth, so you will probably disagree with me at some point.

We released a new version of the introducing Codename One video almost a month ago but we just neglected to highlight it in the blog. Our old videos are pretty dated by now and we use far better toolchains for video production today, so we are in the process of redoing all our old videos. This is a long and tedious process that we do while producing newer content, fixes and moving forward. So the timeline of such updates is quite vola..

I recall extremely early stage where you’d build a feature, realize it was awesome, then the next day write a blog post for it. At some point you start to move from that to more coordinated launches. A larger coordinated launch allows you to reach a bigger audience, can lead to bigger deals, and help expand your overall market. But perhaps more importantly by the time you hit full launch you’ve message tested and ensured it’s going to reson....

And a partridge in a pear tree. Signed up for Janathon (updates will probably be here). Signed up for Dryathlon (Sponsor me!). Decided to do an ad-hoc Jamathon (“Make and upload some musical output every day using one or two mobile apps”). (Yes, I’m going to be insufferable all month.)

Not strictly a music-making app, [Audioshare] gets used for almost all of the things I upload to Soundcloud. But since I managed to accidentally make some “music” with it, I might as well blog about it (and steal the description from Soundcloud). There I was, playing something I’d just made in Soundscaper through Audioshare via Audiobus into Gliderverb when I had the urge to record what was happening since it was sounding ok.

Like a 2D theremin on acid, TC-Performer has a bunch of instruments (all digitally synthed by TC-11 - which is on the wishlist) controlled by multi-touch, movement, etc. Bit tricky to do coherent tunes but excellent for making this kind of swoopy droney chimey kind of space music.

Because of the fact that I personally work for an ad supported company and that searchcode.com is currently supported via third party advertising I tend to keep an eye on the state of ad blockers on the web. Most people probably know about adblockplus and other browser extensions however there are other ways to block ad’s on ones network. One that I had previously read about was setting up your own Bind9 server on a server and adding cust..

Po bitvě u Moháče roku 1526, v níž zahynul český a uherský král Ludvík Jagelonský, se Osmanské říši otevřela cesta do střední Evropy. Turci vyplenili Uhry, dobyli Budín a zastavili se až v Ostřihomi. Hlavní část bojů od té doby přešla na Habsburky a jejich državy včetně Markrabství moravského. České země zachvátil strach...

Packages in Java is a quite simple and straightforward concept of the language. It’s there from the beginning and it’s commonly used by every Java programmer. In a few words, these are the rules you have to follow to create a class inside a package (spoiler: which are not completely true, as we’ll see later): Package statement must be the first one specified in a java class file A package namespace must match the physical path of the file....

In reply to Joaquin. Exactly, this is the right observation to define the sequence that the author implies. I was confused because the values listed on the book didn't make it that obvious to me that this is the right definition.

Now i may be wrong but i think you went completly overboard. If you observe the difference between subsequent numbers of the sequence, youll notice that the numbers missing are the ones on the sequence. 1 3 7 12 18 26 35 45 56 69 2 4 5 6 8 9 10 11 13 The seuqence adds the enxt number with n+1 but it checks to see if that number exists in the sequence if it is go to next number if not add that number. so the next number wo..

Historically, we didn’t use Android’s profiling tools often. They were pretty awful and the only tools that we really used extensively were the on-device GPU profiling tools which were reasonably good. In recent years Android’s native story improved by leaps and bounds with the introduction of Android Studio and 3rd party tools developing native Android apps has improved a lot. But the CPU profiling tools are still stuck in the stone ..

When we started working on Rollup, we knew that we needed to make it easy for application developers to figure out what props a component exp....

More people than ever before are entering software development from non-traditional backgrounds. The number of coding bootcamps is increasing, and there’s a broad push from the industry to attract more diverse developers. Many companies are no longer solely focused on hiring senior developers, and have realized that it may be smarter to train and upskill the next generation of senior developers instead.

My previous post showed a very simple Scalding workflow. Apache Flink is a real time streaming framework that’s very promising.
