It’s rare these to read stories of software billionaires and think it’s well deserved. This is one of those rare cases. Also, IntelliJ runs on Java, for all the bashing that Java gets on HN, it’s an example of how “what technology you pick is less important than your focus on user experience”. It’s amazing that their products are so performant on Java

Going a bit off tangent here: A billion dollars is a ludicrous sum of money. No one on the face of the earth deserves that level wealth. If you ever seen an actual billion dollar product or even a product hundreds of millions of dollars (in cost, not revenue generation) it is always built by hundreds of people. Your physical two hands, strength and intelligence limits you to a lifetime gdp output of well less than 1…

I’m a huge fan of C# and how Microsoft has been improving .NET recently but as a C# fan I think you’re being a little unfair to Java. It has a slightly different perspective on language evolution than C#, in that they try to keep the language core smaller. I was overwhelmed by syntax when I first started programming C#, from all the different kinds of parameters (optional, named, ref, out, in) to all the different ki…

> This is definitely more verbose and arguably uglier, but it hews closer to the object-oriented style because it’s visibly falling a method on an object. Of course this is happening in C# as well, but it’s hidden by syntactic sugar. It's hard to appreciate how addictive the sugar is if you never had it. Frankly, language level auto properties -alone- would get rid of 25-33% of the pain I feel writing Java. Of course…

if JetBrains people are reading this, I want to say THANK YOU! You saved lots of developer time with IDE, then Kotlin language. I use Golang, Python and Database IDEs, and they are really nice and time saving, can't imagine how much time you guys saved to Java developers where everything is reflection based annotations and deep level of abstract class/interface implementations. (last time when I worked with Java in V…

Jetbrains products are amazing if you _need_ and IDE. Otherwise you're much better off using VIM or Emacs as they are open source, have tons of customization and plugins available and also they are simply lighter, faster and are available on all unix platforms.

Java is fast enough for most things, but try working with an array of a million objects in C++ vs Java and you will see the difference. In Java you will have to deal with an array with a million pointers to a million objects and in C++ you will deal with a sequential segment of memory that is a million times the size of your object - and mostly in your CPUs cache. That alone will be much, much faster. But you can't d…

I think in this case you’re holding the tool wrong. When you want, for example, an array of (float x, float y) “objects” in Java, you just keep them as two arrays (float[] x, float[] y) — and I guarantee it will use the same amount of memory and will have nearly the same speed as C++ (depends on what cache locality you need for a specific task, it might even be faster to have two separate arrays for some tasks). So y…
