Project Voldemort : A distributed database

Voldemort is a distributed key-value storage system.

• Data is automatically replicated over multiple servers.
• Data is automatically partitioned so each server contains only a subset of the total data
• Server failure is handled transparently

• Data items are versioned to maximize data integrity in failure scenarios without compromising availability of the system
• Each node is independent of other nodes with no central point of failure or coordination
• Good single node performance: you can expect 10-20k operations per second depending on the machines, the network, the disk system, and the data replication factor
• Support for pluggable data placement strategies to support things like distribution across data centers that are geographically far apart.

It is used at LinkedIn for certain high-scalability storage problems where simple functional partitioning is not sufficient. It is still a new system which has rough edges, bad error messages, and probably plenty of uncaught bugs. Let us know if you find one of these, so we can fix it.

JWIM : A JavaScript window manager that allows programmers to load independent modules inside Web applications

JWIM is a JavaScript window manager that allows programmers to load independent modules inside Web applications. It is totally AJAX based and does not make use of inner frames. Any module acts as an independent page, so it can display HTML, run JavaScript code, get access to HTML elements (in the same manner as document.getElementById does), and can be loaded multiple times. To achieve those features, modules have their own scope to store data and to run code. Modules can be loaded inside dynamically generated divs that behave like windows, or attached to HTML elements to build static layouts. Jwim is primarily intended to split large AJAX applications into small files that are loaded dynamically and run in an isolated environment.

Hudson monitors executions of repeated jobs, such as building a software project or jobs run by cron

Hudson monitors executions of repeated jobs, such as building a software project or jobs run by cron. Among those things, current Hudson focuses on the following two jobs:

1. Building/testing software projects continuously, just like CruiseControl or DamageControl. In a nutshell, Hudson provides an easy-to-use so-called continuous integration system, making it easier for developers to integrate changes to the project, and making it easier for users to obtain a fresh build. The automated, continuous build increases the productivity.
2. Monitoring executions of externally-run jobs, such as cron jobs and procmail jobs, even those that are run on a remote machine. For example, with cron, all you receive is regular e-mails that capture the output, and it is up to you to look at them diligently and notice when it broke. Hudson keeps those outputs and makes it easy for you to notice when something is wrong.
