Web browsers use domain names for a variety of purposes, but how they're used is much more complicated than most developers realize.

The idea is to have one active set per minute. During each request that comes in from a logged-in user, we'll add a user ID to the active set. When we want to know which user IDs are online, we can union the last 5 sets to get a collection of user IDs who have made a request in the last 5 minutes.

There are many design details about implementing Virtual Memory in a key-value store, but well, the basic concept is pretty straightforward: when we are out of memory, let's transfer values belonging to keys not recently used from memory to disk. When a Redis command will try to access a key that is swapped out, it is loaded back in memory.

Protokit is a toolkit for creating HTML prototypes. It uses the following open source libraries and plugins: Blueprint, jQuery, jQuery UI, jQuery Templates, and iXEdit. More information about the included libraries and their licensing agreements can be found in theREADME file.

Developers spend lot of time optimizing performance of web servers. There are many good reasons for doing this, such as fewer servers in a data center and lower probability of overloading those servers. However, the benefits of web server optimization are often negligible for the user experience. Surprisingly, it might take as little as 10% of the total page loading time to download the HTML document that is generated on the fly by the web servers.

FOUT is what I'm calling the flash of unstyled text that you get while using @font-face in Firefox and Opera.

The Study and analysis of different CSS methods for web printing brought me to a discovery that many important web sites are not optimized for printing, even the kind that can be done with little effort.

To solve this problem I decided to make universal Cascading Style Sheets for web printing by uniting all best CSS printing practises into one.

The Web Embedding Fonts Tool (WEFT) lets Web authors create 'font objects' that are linked to their Web pages so when viewed through the browser, pages are displayed in the style contained in the font object.

MMM (Multi-Master Replication Manager for MySQL) is a set of flexible scripts to perform monitoring/failover and management of MySQL master-master replication configurations (with only one node writable at any time).

The toolset also has the ability to read balance standard master/slave configurations with any number of slaves, so you can use it to move virtual IP addresses around a group of servers depending on whether they are behind in replication.
