    Coderetreat is a day-long, intensive practice event, focusing on the fundamentals of software development and design. By providing developers the opportunity to take part in focused practice, away from the pressures of 'getting things done', the coderetreat format has proven itself to be a highly effective means of skill improvement. Practicing the basic principles of modular and object-oriented design, developers can improve their ability to write code that minimizes the cost of change over time.

    SNMP4J - The Object Oriented SNMP API for Java Managers and Agents SNMP4J is an enterprise class free open source and state-of-the-art SNMP implementation for Java™ 2SE 1.4 or later. SNMP4J supports command generation (managers) as well as command responding (agents). Its clean object oriented design is inspired by SNMP++, which is a well-known SNMPv1/v2c/v3 API for C++ (see http://www.agentpp.com). The SNMP4J Java SNMP API provides the following features: SNMPv3 with MD5 and SHA authentication and DES, 3DES, AES 128, AES 192, and AES 256 privacy. Pluggable Message Processing Models with implementations for MPv1, MPv2c, and MPv3 All PDU types. Pluggable transport mappings. UDP, TCP, and TLS are supported out-of-the-box. Pluggable timeout model. Synchronous and asynchronous requests. Command generator as well as command responder support. Free open source with the Apache license model Java™ 1.4.1 or later (1.6 for version 2.0 or later) Logging based on Log4J Row-based efficient asynchronous table retrieval with GETBULK. Multi-threading support. The SNMP4J-Agent pure Java SNMP agent API adds command responder including notification originator and proxy forwarder support to the SNMP4J core API and comes with: Implementations for SNMP-TARGET-MIB, SNMP-NOTIFICATION-MIB, SNMP-PROXY-MIB, SNMP-FRAMEWORK-MIB, SNMPv2-MIB, SNMP-COMMUNITY-MIB, SNMP-USER-BASED-SM-MIB, SNMP-VIEW-BASED-ACM-MIB, NOTIFICATION_LOG-MIB, and SNMP-MPD-MIB, SNMP4J-PROXY-MIB, SNMP-TLS-TM-MIB, SNMP-TSM-MIB. SNMPv1,v2c,v3 multi-lingual agent support, including MD5 and SHA authentication as well as DES, 3DES and AES(128, 192, 256) privacy. IPv4/IPv6 UDP, TCP, and TLS support. Code generation from MIB specifications is provided through AgenPro 3 which is a language and API independent template based code generator with round-trip generation facilities. The SNMP4J-AgentX pure Java AgentX API adds support for the AgentX 1.0 master and subagent protocol as defined by RFC 2741 and 2742. SNMP4J-AgentX extends SNMP4J-Agent by: Full AgentX 1.0 protocol support, including contexts, shared tables, index allocation, ping PDUs, connection timeout handling, etc. Implementation of the AGENTX-MIB for the master agent. TCP transport mapping for the AgentX protocol. Code generation from MIB specifications is provided through AgenPro 3 which is a language and API independent template based code generator with round-trip generation facilities (see also SNMP4J-Agent). The SNMP4J-AgentJMX pure Java 1.5 API adds support easy descriptive mapping from JMX MBean instrumentation to SNMP scalars, tables, and notifications. New in SNMP4J(-Agent) 2.0: Transport Security Model (TSM) including Transport Layer Security Transport Mapping (TLSTM) as defined by RFC 5343, 5590, 5591, 5953. Java™ SE 1.6 or later, including Generics and System.nanoTime() support.

    Ganglia is a scalable distributed monitoring system for high-performance computing systems such as clusters and Grids. It is based on a hierarchical design targeted at federations of clusters. It leverages widely used technologies such as XML for data representation, XDR for compact, portable data transport, and RRDtool for data storage and visualization. It uses carefully engineered data structures and algorithms to achieve very low per-node overheads and high concurrency. The implementation is robust, has been ported to an extensive set of operating systems and processor architectures, and is currently in use on thousands of clusters around the world. It has been used to link clusters across university campuses and around the world and can scale to handle clusters with 2000 nodes.

    What is FreeFileSync? FreeFileSync is an Open-Source folder comparison and synchronization tool. It is optimized for highest performance and usability without restricted or overloaded UI interfaces. Key Features Compare files (bytewise or by date) and synchronize them. No limitations: An arbitrary number of files can be synchronized. Unicode support. Network support. Built-in support for very long filenames (more than MAX_PATH = 260 characters). Synchronization database for propagation of deleted files and conflict detection Support for multiple folder pairs with distinct configuration Full support for Windows/Linux Symbolic Links and Windows Junction Points. Lean & easily accessible UI: Highly optimized for speed and huge sets of data. Algorithms coded in C++ completely. All progress indicators optimized for maximum performance! Create Batch Jobs for automated synchronization with or without GUI. Focus on usability: Only necessary functionality on UI: no overloaded menus or icon jungle. Select all folders via drag & drop. Last used configuration and screen settings are saved automatically. Maintain and load different configurations by drag & drop, load-button or commandline. Double-click to start external application (e.g. show file in Windows Explorer) Copy & paste all grid data as text Delete superfluous/temporary files directly on main grid. Right-click context menu. Comprehensive status information and error reporting Sort file-lists by name, size or date. Support for filesizes larger than 4 GB. Option to move files to Recycle Bin instead of deleting/overwriting them. Ignore directories "\RECYCLER" and "\System Volume Information" with default Filter. (Windows only) Localized versions are available for many languages. Delete before copy: Avoid disc space shortages for large sync-jobs. Filter functionality to include/exclude files from synchronization (without requiring a re-compare!). Include/exclude specific files from synchronization temporarily. Automatically handle daylight saving time changes on FAT/FAT32 volumes. Portable version available (selectable via installer). Native 64-Bit version. Check for updates from within FreeFileSync automatically. Copy locked files using Windows Volume Shadow Copy Service. (Windows only) Create regular backups with macros %time%, %date% within directory names Copy file and folder create/access/modification times when synchronizing Advanced locking strategy to allow multiple synchronization processes (e.g. multiple writers, same network share)
