Common mistake when dealing with Reader in Java

Posted by & filed under , .

I’ve encountered this one a few times and came across again recently and thought it relevant to deserve its own post, so here it is. If you have done any I/O in Java you likely came across the Reader class, unlike the InputStream class(es) which deal with bytes, the Reader makes the transition into reading […]

Dependency overload … or laziness?

Posted by & filed under , .

This is something that started bugging me back in the maven area — when I switched from the likes of Ant as a build tool, which was relying on the user being explicit about a lot of things and doing a lot of the grunt work for it, to the maven world. Now maven was […]

Nicer implementations using Java streams

Posted by & filed under , .

I am not entirely sold on the performance of the Java streams but I will accept they are getting much better compared to the first cut, we now have parallel streams and all sorts, and also it provides a (nicer) functional approach to coding. I’m not going to go into the whole dispute of whether […]

Beware of Governator’s @Configuration annotation

Posted by & filed under , .

If you read some of my posts dealing with dependency injection in Java you have probably figured it out (and I even stated it in clear) that I use Netflix Governator’s a lot. Especially as I revealed in one of my previous posts because Google Guice doesn’t support out of the box the likes of […]

Java Dependency Injection and a Useless Annotation

Posted by & filed under , .

I’ve stepped into the Guice territory rather recently — coming from the Spring framework side of things — and I guess I had so far a similar love/hate experience as with Spring. I rely mostly on the javax.annotation standards anyway so to a certain degree whether it’s Spring or Guice I guess doesn’t make that much […]

AngularJS, Filters and $index

Posted by & filed under , .

I came across an issue with AngularJS in one of the projects I worked on which I thought was worth signalling. It all stems back from the usage of $index inside a ng-repeat group — in the context of using a filter in ng-repeat, and as such it took us a bit to identify the […]

Engineering Marketing

Posted by & filed under , , , .

First of all please notice the title of this post: Engineering Marketing — and not Marketing Engineering! (I do work currently in Ads Engineering in Netflix, which deals as you would expect with Marketing Engineering, in other words engineering solutions to support our digital marketing efforts.) Point being that this post is about marketing engineering […]

The Power of Technical Jargon

Posted by & filed under , , , .

I recently had the chance to reflect over how important jargon can be when building a product and I thought I’d share my thoughts and findings here. A bit of history: a while back (quite a while back now) I helped a small startup (let’s call them Green Media) which operated in digital marketing and online […]

Breaking into open source

Posted by & filed under , , .

I read recently Shubheksha‘s blog post “A Beginner’s Very Bumpy Journey Through The World of Open Source” which describes her initial journeys into the open source world and reminded me a bit of some of my initial adventures into open source. (I even wrote a blog post ages ago — my goodness, literally ages ago […]

Java, Map and Optional

Posted by & filed under , .

I do like the Optional class in Java — it is a long awaited elegant replacement for returning null whenever something isn’t there then relying on if( x != null ) checks or using ?: in the format (x == null) ? “foo” : “bar”. It works great also with the new Java stream classes […]

Thoughts on Programming and Its Challenges

Posted by & filed under , , .

At the end of another tough week in Netflix I look back at what I have achieved and what has been challenging in achieving it. I do wonder what I do looks like from the outside and I can’t really see how someone would make sense of my job. I sit in front of 3 (sometimes more!) […]

Gotcha When Building Gradle Plugins on Top of docker-java-plugin

Posted by & filed under , .

If you use gradle and docker you must have come across the gradle-docker-plugin. And if you started using it a lot you probably found out that more often than not your builds start using the same boilerplate code to prepare your microservices containers. And if you end up in that situation best thing to avoid boilerplate rubbish […]

Disable PMD Plugin to Run for Test Sources

Posted by & filed under , .

I use PMD in my Gradle builds quite a bit. (Maybe a bit more nowadays that the FindBugs peeps seem to be struggling with that project — see this email from Andrey on this: https://mailman.cs.umd.edu/pipermail/findbugs-discuss/2016-November/004321.html). The issue I had with it is that there is no way to quickly turn off their checks for the src/test/… […]
