  A plugin to update last_error in Delayed Job

delayed_job is a process based asynchronous task processing gem which can be ran at background. It will fork the specified number of processes to execute the tasks asynchronously. The task status is usually stored in the database so that it can be easily integrated into a Rails application where asynchronous job execution is desired. Normally when a job fails to execute or error occurs, it would save the error into the database with the column last_error. Ideally all these will be handled b...

  Esmerelda's Imagination

An actress acquaintance of mine—let's call her Esmerelda—once said, "I can't imagine being anything except an actress." To which the retort was given, "You can't be much of an actress then, can you?"I was reminded of this exchange when someone said to me about Go, "I can't imagine programming in a language that doesn't have generics." My retort, unspoken this time, was, "You can't be much of a programmer, then, can you?"This is not an essay about generics (which are a fine...

  TIOBE : Objective-C overtakes C++

TIOBE recently released the programming community index for July. From the index,we can find that the biggest change is that Objective-C overtakes C++ as the 3rd most popular language among programmers. Because of the popularity of iPhone and iPad, Objective-C is used by more and more mobile developers who want to develop apps for Apple products. Also, many developers are willing to develop apps for Apple since they can gain more profit on Apple platform than on Android platform.C++ is mainly us...

  Automate Everything

Performing manual, repetitive tasks enrages me. I used to think this was a corollary of being a programmer, but I’ve come to suspect (or hope) that this behaviour is inherent in being human. But being able to hack together scripts simply makes it much easier to go from a state of rage to a basic solution in a very small amount of time. As a side point, this is one of the reasons that teaching the basics of programming in schools is so important. It’s hard to think of any j...

Today, we will analyze and explore this decision. What is query cache? According to official document: The query cache stores the text of a SELECT statement together with the correspon...

  Pair Programming: The disadvantages of 100% pairing

I’ve written a lot of blog posts in the past about pair programming and the advantages that I’ve seen from using this technique but lately I find myself increasingly frustrated at the need to pair 100% of the time which happens on most teams I work on. From my experience it’s certainly useful as a coaching tool, as I’ve mentioned before I think it’s a very useful for increasing the amount of collaboration between team members and an excellent way for ensuring ...

  ByteBuffer in Java

ByteBuffer is introduced in java.nio since Java 1.4. It provides a way of representing raw structured data such as from a file or from network. It enables fast access of underlying data compared to traditional ways like byte[] Prior to Java 1.4, if you want to represent a structured raw data, you need to create a byte[] and then having a set of checks to delimit the byte array to get the expected tokens. There are three ways to create a ByteBuffer: Wrapping an exiting array by calling ByteBuffe...
