Ruby Thin Web Server

Somebody suggested that I try out thin, “A fast and very simple Ruby web server.” So, I thought it might be interesting to test, and a simplification over Rails to demonstrate an small Ruby MVC pattern.

Installing thin seemed straight forward as a gem installation, like

Find a string in files

From time to time, folks ask questions about how to solve common problems in Linux or Unix. Today, the question is: “How do I find a list of files that contain a specific string?” There are two alternatives with the find command, and the following sample searches look for files that contain a sqlite3 string literal.

Ruby-MySQL Columns

Last week I posted how to configure and test Ruby and MySQL. Somebody asked me how to handle a dynamic list of columns. So, here’s a quick little program to show how to read the list of column:

Java-MySQL Program

It turns out that configuring Perl wasn’t the last step for my student instance. It appears that I neglected to configure my student instance to support Java connectivity to MySQL. This post reviews the configuration of Java to run programs against MySQL. It also covers the new syntax on how you register a DriverManager, and avoid Java compilation errors with the older syntax.

APEX 5: forgot the images?

On my play environment I usually use Oracle APEX with the Embedded PL/SQL Gateway, just because it's so easy.

MySQLdb Manage Columns

Sometimes trying to keep a post short and to the point raises other questions. Clearly, my Python-MySQL Program post over the weekend did raise a question. They were extending the query example and encountered this error:

Perl-MySQL Program

Python-MySQL Program

The Fedora Linux distribution installs Python 2.7 by default. Unfortunately, the MySQL-python library isn’t installed by default. You can verify the Python version by writing and running the following version.py program:

In what ways is buckthorn harmful?

I spent 10-15 hours a week in various locations of still-wooded Chicago (and now nearby Lincolnwood) cutting down buckthorn. Some people have taken me to task for it ("Just let it be, let nature take it's course, etc.). So I thought I would share this excellent, concise sum up of the damage that can be wrought by buckthorn.

MySQL JSON Functions

What the MySQL team is doing with JSON (JavaScript Object Notation) in MySQL 5.7 is great! The MySQL Server Blog (Rick Hillegas and Dag Wanvik) published two key articles about new JSON functions. If you don’t follow these, let me highlight them as a set:
