Simple jQuery: how to validate IPv4 addresses and netmasks
+0 Vote Up -0Vote Down

Unfortunately jQuery doesn’t come with default form validation to check for ip-addresses or subnet masking. So without a long winded explanation here’s the code. Just include this as a separate JS file like the rest of your page’s JS.

// 'ipv4': IPv4 Address Validator
$.validator.addMethod('ipv4', function(value) {
    var ipv4 = /^[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}$/;    
    return value.match(ipv4);
}, 'Invalid IPv4 address');

// 'netmask': IPv4 Netmask Validator
$.validator.addMethod('netmask', function(value) {
    var mask = /^[1-2]{1}[2,4,5,9]{1}[0,2,4,5,8]{1}\.
[0-2]{1}[0,2,4,5,9]{1}[0,2,4,5,8]{1}\.
[0-2]{1}[0,2,4,5,9]{1}[0,2,4,5,8]{1}\. …

Welcome to Insatiable Demand

In early 2006 Paul Hurley (ideeli’s CEO) and I (Mark Uhrmacher, CTO) were thinking about a new business. We had the idea to create a community based around great deals for Women’s fashion products where we saw a great deal of potential for great content and product sales. Now, over five years later, we’ve realized much of that vision. Our business success has been chronicled over the years in several places (see here and here). Though we’re very proud of our achievements there, that …

Why is my database slow?
+0 Vote Up -0Vote Down

Not part of my Don’t Assume series, but when a client states “Why is my database slow”", you need to determine if indeed the database is slow.

Some simple tools come to the rescue here, one is Firebug. If a web page takes 5 seconds to load, but the .htm file takes 400ms, and the 100+ assets being downloaded from one base url, then is the database actually slow? Tuning the database will only improve the 400ms portion of 5,000ms download.

There some very simple tips here. MySQL is my domain expertise and I will not profess to improving the entire stack however perception is everything to …

memcached and the client: Database UDFs
+1 Vote Up -0Vote Down

NorthScale's own Patrick Galbraith has, for many years now, authored and maintained the MySQL, and now Drizzle, UDFs for memcached.  Last week, Patrick took this one step further with the latest release, version 1.1, which now includes support for "check and set" (a.k.a. CAS) operations.  

User Defined Functions are available for a number of different databases.  This allows some kind of stored procedure language or other triggers to execute other code imported into the DB.  In the case of the memcached UDF, this means giving …

Some Drupal observations
+0 Vote Up -0Vote Down

I had the opportunity to review a client’s production Drupal installation recently. This is a new site and traffic is just starting to pick up. Drupal is a popular LAMP stack open source CMS system using the MySQL Database.

Unfortunately I don’t always have the chance to focus on one product when consulting, sometimes the time can be minutes to a few hours. Some observations from looking at Drupal.

Disk footprint

Presently, volume and content is of a low volume, but expecting to ramp up. I do however find 90% of …

An intestesting approach to free hosting
+0 Vote Up -0Vote Down

I came across the OStatic Free hosting service that provide Solaris + Glassfish (Java Container) + MySQL.

They offer “Now you can get free Web hosting on Cloud Computing environment free of charge for up to 12 months.

The catch “accumulate 400 Points for participating on the site“.

A rather novel approach, you get 100 points for registering, but then only 5-15 points per task. The equates to approximately at least 30 tasks you need to perform, such as answering a question, or reviewing somebodies application. That seems like a lot of work?

In this case, Free has definitely a cost and time factor to consider.

Trying out Google App Engine
+0 Vote Up -0Vote Down

I got my registration for Google App Engine this morning after being Waitlisted previously.

Between flying for about 15 hrs tomorrow and then the 2008 MySQL Conference & Expo where I’m presenting and running an Exhibitors booth, fat chance I’ll get to look into this much over the next week.

Pity!
