At the very beginning of 2014 I decided to start better documenting my reading habits and sharing them here with all of you.
The point is two fold – by curating and documenting, my reading has become more purposeful and diverse. Also – I believe that curation of good content brings a lot of value, helps people explore and allows the best stuff to raise to the top.
Hopefully you'll enjoy these as we move in the latter half of 2014.
Here we go…
A solid start for this weeks review – Petri goes over some good practices for testing an application. The 3rd point about transactionality is especially important – don't test with different transaction semantics.
It's also quite funny: “We have two options: the right one and wrong one”.
Generics over primitives are comming to Java (perhaps reification as well) – Brian Goetz published a very early proposal that's definitely worth reading.
Next on the list – further on generation of identifiers with JPA – this series is going to be a great resource to go deep into persistence with both Hibernate and JPA.
Who says that Java 8 is deprecating Guava – here's a good primer on collectors that shows they can play well together.
An elegant use of streams to flatten and traverse an directory on the file system.
This is one of these areas where I'm doing things so much differently now than I was even a few years ago. My view on tests and @Transactional is no.
Why not? A few reasons – one, I find it valuable to have the tests consume my system and my APIs with the same transaction semantics that they're actually consumed in production; changing these will make things subtly different – and subtle differences in tests are – in my experience – not good.
A second reason behind the `no` is that knowing that I'll have junk data and the end of my test suite run makes me write the test logic in a certain way, really think through some scenarios and, overall, has a positive effect on the flexibility of the tests.
But that's my own preference, and as Marco opens the article with – it depends. All in all – a good article to read.
Spring Data just got a little bit cooler – nuff said.
ALPS metadata is new to me, and this article makes it look quite interesting – perhaps a step forward from the slow pace the hypermedia types are getting standardized.
Worth a look – and will probably require some digging to really get a good idea of what this kind of metadata can do for an API (digging that I'm planning to do during the weekend).
A new STS is out – and since it's a tool I use every day, I was quick to upgrade; if you're on Eclipse and doing Spring – there's really no reason to not give it a go.
3. Technical and Musings
While I didn't have the chance to see this part yet, I've been covering the entire series in my weekly reviews since the very start, so I have no qualms recommending it even before I see it this weekend. The series is jam packed – and, if I'm being honest, it's something that should probably be productized and sold – but since it's free – go through it and you'll pick up a lot.
Nice continuation of the first interview tips article – I've been on both sides of the interview table and what I found personally is that being the interviewer is much harder (for me). There's a long, long way to go until you're a half decent interviewer – and this is a decent list of things to keep in mind when you're in that position.
