Our Universe is expanding every day — and I mean this in the sense of our “programming universe” (though the other, ad literam interpretation is true as well, since our actual physical Universe is expanding indeed). Every meetup and every website I come across advocates a new framework, a new architecture, a new language, a […]
I have been a CTO myself a few times and worked for some of the greats (and learned!) so I get asked often about what are the traits of a good CTO, be it by the companies I’m advising privately and also through Endeavor mentorship sessions. If you are a co-founder looking for a CTO […]
This is something that comes up often in sessions through the Endeavor network or with companies I advise so I thought it worth a blog post. Imagine a situation where you have a startup, you are in the right place and have the right skillset to scale this up, you build up your engineering team […]
One of the challenges I have seen teams struggle with nowadays is versioning their packages. One of the problems with adopting any versioning system is that typically you have to version (at least) 2 components: the binary you are releasing AND the source code, at the time you have built the software. Doing this allows […]
I’ve tweeted enough about this during the conference itself so you would have seen all of these images before, but if you want a “no subtitles” image-only version here it is — going through the images they actually do tell a story themselves to be fair! Many thanks to Hilton hotel San Jose for hosting […]
Have you heard of hashCode() and equals() in Java and the eternal discussions around this? And you know by now the implications of having a messed up relationship in between hashCode and equals so you make sure every time you implement a class with an equals() you have to make sure hashCode() follows suit right? […]
I use RxJava a lot nowadays — back in the day before I joined Netflix I was struggling with it a bit and mostly watched from the sideline but nowadays I find myself pulling in that dependency in a lot of the Java code I’m writing. And I also use the Spock framework a lot […]
It so happens that in a few of the apps I work on here in Netflix we use Jersey libraries inside a Tomcat container. As such I use the JSR annotations a lot safe in the knowledge that Jersey will take care of all the plumbing work and deal with routing and serialization/deserialization so I […]
This is an obvious one but I find myself so often using it and every single time it means I have to spend extra time debugging my test / code until I realize that I’ve fallen for the same mistake again. I’m using RxJava here and using Groovy and Spock framework for testing — and […]
When dealing with OOP languages, composition over inheritance has been the preferred approach for a while now as it offers a greater flexibility in most cases. Before you start, I’m not going to get into that dispute whether one should opt for inheritance or not, enough to say that there are cases where composition is […]
