The key to being productive as a programmer is to have a great code editor. I have been an avid user of Atom since 2014, and its successor Pulsar since now in 2023.
Pulsar (former Atom) is still the best code editor in my opinion. It is easiest and fastest to use, has all the nice productivity boosting plugins and is overall great for all the same reasons the Atom was great. 🚀
Pulsar is a fork of Atom, which was discontinued because almost everyone jumped ship to VSCode.
What does Pulsar do that is better than VSCode? All the features this article highlights are in VSCode too, and I can think of a bunch of features that Pulsar doesn't have (dev containers are a big one for me - they allow you to have different versions of the same software installed, depending what project you're working on right now... and you can work on/run both versions of the same software at the same time, on the same hardware... you can also emulate other CPU architectures in a dev container, some of the software I work with every day can't actually run natively on my hardware).
The author also makes some incorrect or misleading claims, specifically about emacs. I acknowledge there's a high bar for entry there and don't personally like emacs, but it's not modal, and it does have the ability to display images and markdown previews.
I recently started learning Java and Intellij Idea was recommended to me by the course. This is the second time in a week I've heard about this. In your opinion, what makes it good?
It just works. I spent years with Eclipse (but quite some time ago now), and it was always a pain getting particular things to work properly. The last time I messed with it was doing research for an article I was writing. I was try to get Gradle support enabled. I wasn't able to do it, but I admit I gave up pretty quickly because I don't have the patience for messing with tools that don't work any more.
In truth, I really liked the Open aspect of Eclipse and I wish it work better than Intellij. Maybe it does now - I don't know. For Java Intellij is awesome, and does everything you could ever dream for. For Kotlin - well Kotlin is an Intellij product and the support for it is awesome.
