  Testing is not a Feature

I pointed out to someone at work today that PyDev 2.5.0 now offers really cool TDD support. I’m not a huge TDD proponent or anything, but this stirred up a discussion. This guy, let’s call him John, said that â€œTDD may shorten the time it takes to develop a feature, but sometimes a feature is so urgent we may want to deliver it as quickly as possible and test it later”.Sentences like that make me weep. I tried to explain that without testing, the...

  Why Apple Mac switches its CPU? The war between Intel and ARM

About three months ago, the new iPad Pro was released and it supports touch pad and mouse. It conveys a clear message to users that they want people to treat iPad Pro as a laptop.  As we know, iPad and iPhone are both using iOS, if iOS can run on laptop,  it means MacOS and iOS can merge and become a unified OS. And if Mac and iPhone can share the same OS, it means the same app can run in all places. It is becoming clearer and clearer that Apple is planning to do this exact thing. Late...

  C++ and Java over Python in Google products

In Google, most of the products are written in C++ and Java. They usually don't choose Python to write their product stack. What's behind the decision to choose one language over the other in Google? Let's get to read some opinions from Robert Love, a Google software engineer. Love said he couldn't imagine writing let alone maintaining a large software stack in Python. They use C++, Go, and Java for production software systems, with Python employed for scripting, testing, and tooling.There are a...

  Arrays.equals() vs MessageDigest.isEqual()

Both Arrays.equals() and MessageDigest.isEqual() are used to compare the equality of two arrays. They can be interchangeably in many cases. However, they do have some differences which lead to different use cases in real applications. One difference is that the arrays passed to MessageDigest.isEqual() cannot be null while it's ok for Arrays.equals(). The one major difference between these two methods is that Arrays.equals() is not time-constant while MessageDigest.isEqual() is time-constant. Thi...

  Why you don’t need a programmer

Once or twice a month I get the question from an aspiring entrepreneur that’s been pushing their idea forward in hopes to (very soon) create a company out of what they’ve been working so hard on.  They’ve spent countless hours working through all the details of what this new product will do, who they’re going to partner with and what they’re going to charge for it. They may even be on the Lean Startup bandwagon and actually talked with potential custo...

  How to teach "Modern" Perl?

Since I started my Perl Tutorial series a couple of people commented on what and how I am teaching.Some people asked why did I show "open or die" and why not using autodie. Others recommended the use IO::All instead of open.Another complaint was the introduction of time and localtime instead of DateTime.While I was mostly writing parts of my regular training material these comments led me to think about it again. I wonder how to teach Perl in 2012?When I started to write the tutorial I still cal...
