We make fun of Ruby a lot here: 1. because it’s fun and 2. … …okay, it’s just fun really, but a question did come up recently from an individual who was offered a job working with Ruby on Rails. They come from a PHP – Laravel background and while they don’t know how to use Ruby, per se, their potential employer also offered to pay them while they learn it. So the question was do they take the job knowing that the use of Ruby on Rails has diminished or should they look for something else?
Now Ruby aside, we’d like to answer this question in general terms if you ever find yourself in a situation like this and you’re on the fence… “If you don’t have other work and the job is high paying, why not? …A language or framework does not define you as a programmer… you [just] happen to be using those tools at that particular time”. Now, specifically regarding Ruby jobs: “…it’s not gonna disappear over night and in fact we’ll probably see Ruby development for the next five years, at least, so …you do that for one year, two years, 3 years; what have you…”
Another question we’ve been getting recently is if Java is dead? With Google making the switch to Kotlin for app development and Oracle charging for Java licensing, what will be happening to Java jobs? “Does that mean the whole Java-Android development is going to collapse overnight? Probably not: it won’t, it’ll probably take a couple of years.” That being said, “if you’re writing code for your android app using Java, you’ll be able to transition into Kotlin very, very quickly.”
Check out the VLOG for a more sensible and detailed answers to these questions, and remember, “you cannot lose learning any programming language.” -Enjoy!
The tech giant will still support Java but Kotlin is king for Android development.
A quick snippet to be sure, but Google has announced that when it comes to Android development, going forward it will use Kotlin. There will still be support for Java, “…but in terms of documentation, new libraries and so fourth…they said, ‘that’s it! Kotlin is our beast’.”
Without sounding like a broken record (probably a dated reference…), this does go back to what we were saying about a language that is easy to write in, generally gets more use/support and ends up winning out over more verbose/heavy languages. “Kotlin is an easier language to write in, it’s far more productive so…if you are looking for native Android development (and that I think is going to diminish over time…), …then I would lean towards Kotlin.”
The VLOG goes onto mention other casualties in the “simplicity wars” of languages and frameworks, like Apple’s ‘objective C’ being replaced by Swift. It’s worth a look just for the nostalgia factor alone. -Enjoy!
We get comparison questions a lot: Is it better to learn x or y? Is this language even worth learning over that language? The most recent example: Is Java and Kotlin development dead for Android development? When compared to progressive web apps (PWAs), which while more ‘generalized’, can be faster, and can cross-platform(Android & iOS) so you only have to write the app once, it’s easy to see why native tech would not be long for this world.
Our answer is, “I think native dev is going to be important for awhile…[but] there’s nothing to be lost by learning any language, as I said you can’t lose when you learn – even if you don’t end up using the technology.” “…Because what you’re going to see as you advance as a developer…is that all these frameworks, all these languages share many, many, many, many things in common and in fact when you learn your second framework, when you learn your second and third and fourth language (which will eventually happen), learning the new languages and frameworks are going to make you more knowledgeable of all the frameworks and languages you learn.” So, if you learn Java and then you go into PHP, you’re going to find the PHP is “…pretty much like Java. Yeah there’s some differences here and there but whatever; a function’s a function, a method is a method, and arrays are arrays…”.
Check out the VLOG for a more eloquent explanation of this thinking, but essentially, learn as much as you can because most languages have more in common than different, and you can’t lose from learning. -Enjoy!
…That’s ‘Positive Mental Attitude’ for ‘Progressive Web Apps’…
We keep on getting requests to cover PWA/RWD’s and because we’re not DJs or that small band at the back of the bar that’s playing ‘only originals’, we’re taking those requests…and 5-6-7-8…
So a PWA is a progressive web app and an RWD is a responsive web design. How are the two related? Well first off, “RWD is basically writing your HTML5 and your CSS code so that the layout of the site will flex and change depending on the size of the screen of the web browser that is visiting your site. So if you have a smartphone or a 75 inch flat panel TV, a properly coded responsive website or web app will look just fine.” So the idea being that fonts, images, layout, etc. will change size depending on the size of the screen you’re viewing them on. As you can imagine, with the way consume data and media, it was a pretty big deal.
Okay, but where does the PWA come in? “…A PWA is basically taking RWD to its ultimate highest level. Essentially…you can think of it as RWD on steroids, because it brings in all the power that comes with native HTML5 and CSS (and you throw in some JavaScript to add some extra capabilities, of course…).” “The big advantage of using a PWA over native is you have one code base, so instead of having to write one app in iOS with SWIFT, and then having to write the whole app again from scratch for android in JAVA or KOTLIN. PWA is a lot cheaper to get your app out there, and [while] you don’t get the full benefit with a PWA that you get with native, you get a lot of the benefits.”
Now the VLOG will go into really good detail weighing the pros and cons of PWA or native (and believe me there are way more pros), but as a dev or a freelancer you should always be thinking about where businesses are coming from. Most of the time they’re not interested in the “nerd” implications of the languages, frameworks, etc. that you use, they just want to get up and running fast and get the product or service out there and PWA is your best bet. -ENJOY
Kotlin is a general purpose, open source, statically typed “pragmatic” programming language developed by “Jetbrains” and endorsed by Google. As a light, nimble way to take advantage of the vast Java ecosystem and libraries, without the weight of Java code, spoiler alert…it’s gonna be pretty awesome. Now that being said, should you drop everything (including JAVA) and start learning KOTLIN?
Not necessarily. As we’ve said before stick to your fundamentals/basics, remember: “Newb programmers will think in terms of languages, -OMG, my career is based on THIS language- The reality of the situation is advanced developers will move from language to language, from framework to framework, depending on the requirements of the job at hand, depending on where the work is.”
So what’s the big deal about KOTLIN? Well it’s more about what KOTLIN represents… it’s a lighter/faster version of JAVA, it’s pretty versatile in terms of what it can be used for (including android apps), and to put that into perspective, “lighter languages tend to win out over other heavier, more verbose languages”. With computers getting more and more powerful and faster and faster, the preferential choice is given to languages that are quick, adaptable and versatile, and KOTLIN checks all these boxes.
Now, like we said in the second paragraph, there’s no need to drop everything and worship new and fast, especially if you already know JAVA, JAVASCRIPT, C#, PYTHON, PHP, etc… they share so many similarities that you could jump into them relatively easily. If anything, rejoice guys! Stick to you basics and your job may be faster and easier…and hopefully more fun too.
