where Swift is overtaking Objective-C rapidly and the momentum is clear. In the
Android world, presently, the language option is not that clear.
Yes, Kotlin is
there, new, coming forward, garden-fresh, 21-century ready but it isn’t ultimately
taking off, not as expected.
Kotlin was first
introduced by JetBrains in 2011, which is the creator of IntelliJ IDEA,
PyCharm, and many other top IDEs. It got its name from ‘Kotlin Island’ in St.
Petersburg, Russia. Made to strike Java.
That said, the
dominance of Java is still immense, the number of libraries, APIs, code
generally speaking is humongous. Not to mention the readability of it, the many
algorithms and things done or thought already in Java, yeah… Simple as it
sounds, it’s hard to break a solid present for a “uncertain” bright future.
One of the most exciting aspects of the software development process is experiencing the steps leading to a pleasing solution to your problem. That moment when, after some time of thoroughly brainstorming, everything falls into place. I had such a moment today, and I would like to share my story.
This morning I was faced with a simple dilemma. I needed to perform a GET request containing a large payload to the server, but I didn’t want to show it in the URL. The reason for the GET request is that I wanted to give the user the ability to download a file with a click of a button. The purpose of the large payload, the requirements for this file. You see, this file is a zip archive that the service will dynamically construct and deliver to the user. The issue is it can potentially contain thousands of files inside, and I didn’t want to clutter the URL with this payload.
That is when it hit me! I have been using Redis for some time now, and I thought this would be a great use of it. With that in mind, I set up to develop the following idea.
Conferences.digital is the best way to watch the latest and greatest videos from your favourite developer conferences for free on your Mac. Either search specifically for conferences, talks, speakers or topics or simply browse through the catalog – you can add talks to your watchlist to save for later, favourite or continue watching where you left off.
As soon as new conferences/talks have been added it will be announced on twitter.
Complexity in data structures is defined for each of its actions (access, insert, delete, search) and dictionaries shine on three of these operations. Because of this, they become useful in reducing the complexity of many algorithms when you apply a clever use of them. For dictionaries, accessing, deleting and inserting operations could be achieved quickly despite the number of elements they have. So let’s pick up our headset and get to coding while we listen to smooth jazz (hint hint, Kenny G).
Let’s consider the following problem: Write a function that prints a count of how many times all letters appear in a given string. To simplify the use of dictionaries I will decide to use PHP, but this approach could be seen in almost any language. Continue reading Why I like dictionaries so much?→
