Python Interface to MySQL
Employee +1 Vote Up -0Vote Down

There has been a lot of discussions lately about various non-SQL languages that provide access to databases without having to resort to using SQL. I wondered how difficult it would be to implement such an interface, so as an experiment, I implemented a simple interface in Python that similar to the document-oriented interfaces available elsewhere. The interface generate SQL queries to query the database, but does not require any knowlegdge of SQL to use. The syntax is inspired by JQuery, but since JQuery works with documents, the semantics is slightly different.

A simple example would look like this: …

On Password Strength
+6 Vote Up -0Vote Down

XKCD (as usual) makes a very good point – this time about password strength, and I reckon it’s something app developers need to consider urgently. Geeks can debate the exact amount of entropy, but that’s not really the issue: insisting on mixed upper/lower and/or non-alpha and/or numerical components to a user password does not really improve security, and definitely makes life more difficult for users.

So basically, the functions that do a “is this a strong password” should seriously reconsider their approach, particularly if they’re used to have the app decide whether to accept the password as “good enough” …

Generating dimension data for dates
+0 Vote Up -0Vote Down

Most analytical and BI databases have date dimension table(s). One frequently needs to generate and populate such data. I present a solution below for such data generation, written in Python. Please use different database drivers/modules to connect to your specific database server (MySQL, SQL Server, Oracle, etc.) for data population.

Notes:

1. It takes 2 parameters, start date and end date, in YYYYMMDD format, inclusive. Extensive error checking is built in, but let me know if you have comments/suggestions;

2. The script produce a Python dictionary (associated array) and print out its content;

3. The output includes …

Connecting to MySQL with Perl
+0 Vote Up -0Vote Down

When I was designing web sites, for a long time I wrote my HTML code the “hard” way – by opening a text editor and manually typing in the code (this was before I purchased Adobe DreamWeaver).

During that time of manual HTML writing, I had a project that required forms on a web page, and I needed a place to store the information. After talking with a few tech friends, I decided to use MySQL as my web site database, and Perl as my scripting language.

I had written complex Bourne shell scripts before, but Perl was something …

A comparison of HandlerSocket and mysql client libraries with Python
+0 Vote Up -0Vote Down

I’ve done some benchmark testing of 2 Python modules for MySQL data retrieval: MySQLdb and pyhs. MySQLdb uses MySQL’s client libraries, whereas pyhs uses HandlerSocket that bypasses MySQL’s client layer and interfaces Innodb storage engine’s files directly. In my testing, HandlerSocket results in 82% improvement over mysql client …
