ical2exchange

When you manage your calendars in iCal but want to replicate your events to Exchange while maintaining control over event filters, private setting and the frequency... ical2exchange is a simple, clean alternative to full, often expensive, synchronization solutions. Simply point it to one or ... [More] more Web-based (Url) or local (path) iCal files, configure your Exchange 2007 connection and let it rip. v 0.1The initial release is here. I tested the app in replication of my work and personal calendar to Exchange 2007 server at work. A couple limitations in this version that I plan addressing in the future. All Exchange events will be deleted and the Exchange calendar will be populated with iCal events. The mechanism to stamp each event in Exchange with the unique iCal event is already in place but I had not figured the update logic fully yet. All configuration values are stored in clear text at this time. In future I plan on allowing for optional encryption. Other than that, the app works as advertised. [Less]

finefs

FineFS is a simple replicated filesystem, which aims to create data clusters. It is designed for web applications, but can be used for any other usage which needs data replication between machines. Data consistency. Writings are atomic. You never get files that are in-modification state. ... [More] Robustness. Using failure detection and retry strategies, temporary shutdowns are managed without data loss. The fully decentralized design avoid any single point of failure. Synchron/asynchron process. Files information are synchronously distributed across the cluster, while binary data are asynchronously replicated. High-performance. Data are eventually replicated on local hard disks, for better optimization of basic operations (data read and write). Easy to deploy and maintain. Based on well-known technics, FineFS is easy to set-up and doesn't need some extended maintenance. Featured documentationPresentation Technical information Architecture design Protocol description How FineFS works: Add a new file, Fetch a file Installation instructions How to develop an application that uses the FineFS PHP library Performance benchmark when FineFS is used as a non-relational database Why use FineFS? For example, you have many frontal web servers. You need to share the same data over all machines. You can set up a file server. But it is a single point of failure. If the file server fall down, you loose all data. You may prefer to use a Storage Area Network. They usually provide some fail-safe mechanisms. But they are also very expensive, and you must set a high-speed link between the SAN and your servers because data are always accessed through the network. You can use an external service like Amazon S3. But it may be a shame to have some empty disk space on your servers, and data access may be really slow. It is possible to set up a distributed filesystem, like Coda, Ceph, POHMELFS, GlusterFS, GfarmFS, Tahoe, Moose FS, Chirp, GFS, ... But these systems may have some technical restrictions or different design goals (like computing grid), and they are hard to install and maintain. FineFS is an easy and convenient mean to create a cluster. Data are accessed locally most of the time, or fetched over the network if necessary. [Less]
