A Better HAProxy Health Check For Dynamic Websites

Nobody wants their website to go down, or worse, for users to notice the site is down. Because of this most larger websites will run on multiple servers to provide some level of high availability. In a multi-server architecture there is typically a load balancer (or cluster of load balancers) to distribute the load among a pool of web servers. When a server goes down it’s taken out of the pool until it is once again ready to handle requests. HAProxy (a software load balancer) has the ability to perform this task by doing periodic health checks on all the […]

Taking The Pain Out Of Domain Hunting

Coming up with a suitable name for a business, product, or website is something I do on a fairly regular basis. In brainstorming a name I often make lists of words I’d like to use, like adjectives and nouns than relate the product. Then I start combining the words to create a unique name and check to see if the related domain is taken or not. The problem is that even though I may have come up with a name I really like, if the domain name is taken, it isn’t worth keeping.

.htaccess File Causes 500 Internal Server Error on Network Solutions

How’s that for a search engine friendly title, eh? This is just a quick note for anyone who has to deal with Network Solutions hosting (for clients or otherwise). Apperantly Network Solutions doesn’t run PHP with Apache’s mod_php, but rather as a CGI application. That means if you try to put PHP configuration directives in a .htaccess file it will cause a 500 Internal Server Error. My helpful reference: Because Network Solutions Sucks. You have been warned.

LongURL Integration For Your Website

I wasn’t sure it could be done, but I’ve done it. I’m happy to say that I’ve made it even easier to use the LongURL web service, specifically on your own site. Today I wrote a jQuery plugin that allows you to add LongURL support to a website in like, I don’t know, 30 seconds?! It really depends on how fast you are, but the point is that it’s really easy. I noticed that Twitter search lets you expand URLs from some of the most popular shortening services (though, if they used LongURL they could support a whole lot more […]

CouchDB View Generation

An alternative technology quickly gaining popularity these days is CouchDB, a document-based database system for semi-structured data. I wasn’t sure what that meant at first, so I read as much as I could about it. The result? I couldn’t wait to use it. I decided CouchDB would be a good fit for my next project (which I should be releasing sometime this week BTW) and rolled up my sleeves. Because of the amount of data I’m working with, I hit a few snags along the way with regard to CouchDB view performance. Some of the things I learned, although they […]
