When I started working with Cucumber JVM it took a while to get the knack of how to write nice and efficient step definitions. Being a regular expression ninja certainly helps but you can get by with a few examples which will enable you to write a wide range of Cucumber steps. Below are some I found the most useful.

If you want to check how many lines of code you’ve pushed to a Git repository, you can do it by git log.

Two ways to get the numbers, using gawk and awk repectively:

Servlet 3.0 has many new features like pluggability and the extension support, asynchronous execution of processing,and a new set of annotations.

And with these annotations, we can write servlet completely without web.xml.

A frequently emphasized advantage of XML is the availability of plenty tools to analyze, transform and selectively extract data out of XML documents. XPath is one of these powerful tools.

The SS proxy is proven to be faster and more stable than SSH. Here is an introduction on how to build SS server on a VPS.

Ususally we use SED for stream processing which process text line by line (SED reads line by line, removes any trailing new lines, places a line in a pattern space buffer, process as per the given commands and prints the pattern space.)

In the last two days we had a great weekend at Xinchang. We visited the famous Grand Buddha Temple and the food in the hotel were great too. We all had a great time together and looking forward to the next outing!

To monitor the connections used in Oracle, you can use below SQL to get the data.

There are different ways to clone a database in MySQL.

Here is an introduction to pattern format in .gitignore.
