Episode 38. Hyperthreading, L1/L2 caching, cache busting, thread trashing, and priority bumping!

So we hear about HyperThreading and how it is sooo cool, well, it is and it isn’t. If you are really trying to squeeze performance out of your application HyperThreading might not be what you’re looking for. There are so many other things that happens at the CPU level that have so weird names (like Thread Thrashing, ‘say whaaaat?’). If you are really serious on squeezing every worthy CPU cycle of your app (or if you’re interesting on what really really goes under the hood) take a listen! (ah! and treat me a beer, if you like what you hear!)

Episode 37. Of Bits and Masks and Bytes and Trees and Games

Have you ever wonder how bit masking work (or what is that?) and why do you need it? Or why a tree structure exists? (or what is breadth first vs depth first), or what are game trees? We put our Computer Science hat and go “depth first” in some fundamental compsci concepts, and, more importantly their utility, ending with Game trees (and they are not only used for games)!

Episode 36. An Intro to Multithreading Programming

This is a presentation I did for the Chicago Java Users Group on the topic of multithreading. There are some solid foundations in here to start tackling multithreading programming. Some of it might’ve been already been seen in depth from our other episodes, but in all, it has good foundations for anyone that does multithreading programming.

Episode 35. Recursion, Doubles and Strings (A little for everyone!)

You remember recursion right? that ugly, confusing thing they made you do either on CS-300, or at job interviews. Have you ever wondered how to make it safe and right? and why do we really use recursion? In this episode we go into proper recursion programming (and lose the fear of making it wrong), and understand why stacks get filled with it, and what problems do they really solve (answer, not many).
In addition we talk about the nature of Double objects, vs double the primitive (And why it is so hard to do == comparisons in doubles), plus some little known things about Strings (like interning). In all it has a little bit for everyone, so take a listen!

Episode 34. New Year’s (2013) Resolution! Less bugs and more coverage!

Episode 34. New Year’s (2013) Resolution! Less bugs and more coverage!

Ok, so we all celebrated (but may not remember) the end of the old year and the beginning of a new year! This is a time for starting new things, and trying to be a little better. How about starting by looking at our code and squish some bugs! By using findbugs we can easily test for the ‘duh’ (and some not so duh) bugs quickly by looking and automatically analyzing our code. After adding Findbugs, we can then add Emma, which will look and measure our unit test code coverage (if you are into such a thing). These two tools are like the Richard Simmons that let us lose the unwanted bug weight in this new year!

Episode 33. Does code dream when it hibernates? A quick look on the big things of Hibernate

Databases have been around forever! (or at least from the 1970s) and there are many things that try to hook Object Objected Programming with Relational Databases (namely, O/R mappers). Hibernate is the most known O/R mapper and, while effective sometimes it can be confusing. In this podcast we delve on how to understand our misunderstood friend, and finally fix those pesky weird Hibernate exceptions once and for all!

Shout out to the Chicago Java User’s Group! Glad to be part of the Board!
And Shout out to Peter Hendriks and Tim Prijn for their presentation! (https://oracleus.activeevents.com/connect/sessionDetail.ww?SESSION_ID=4153). If interested, click on the ‘media’ icon on the right side!
With the establishment of Java 7 as the de-facto JRE of Oracle, the clock is ticking down for Java 6! It will be End-Of-Life around February 2013, so we better get going and upgrade! In this episode we cover how to migrate to Java 7, and cover some of the most notable Java 7 features (Networking nuts, your prayers have been answered!) while preparing a path to upgrade. If you have a Java 6 (or 5 or 4) project, this is mandatory listening!

Episode 31. Know your bounds! Generic bounds that is (a story that extends super!)

Big shout-out to everyone I met at JavaOne (including some avid podcast listeners!). Thanks for listening and for a great time down at JavaOne! Don’t worry, we will be sharing all the stuff I learned on new episodes of the podcast.

It is also our Birthday (We have been airing episodes for a year!)! Happy to celebrate with everyone a year of the podcast (and if you want to celebrate it, treat me a beer! 🙂 ).

With this episode we wrap the concept of generics and bounds (super / extends) and talk about type erasure (and compiler warnings that goes ‘Hm, dunno what you’re doing but I can’t make sure it’s right’

And, that…is that!

Episode 30. I always thought Generics were as good as brand name Erasers (Java Generics part 1)

Hi there! Finally back on a (hopefully) standard schedule. I have been moving a house with three kids, two cats, one wife, one dog, and one grandma (they are heavy!, just kidding!) and just found the box with the podcast equipment!

we hit the ground running with Generics. What are the benefits (and potential pitfalls) of Generics? Why do we even need them at all? The syntax looks pretty confusing, but with some Jedi Mind tricks one can actually start seeing how they work. If you use Generics (Almost everyone does :)) you should take a listen!
