- Welcome to the Ubuntu Manpage Repository This site contains hundreds of thousands of dynamically generated manuals, extracted from every package of every supported version of Ubuntu, and updated on a daily basis. Traditionally, manpages are browsed on the command line. This project renders all such manuals included in Ubuntu in an HTML, web-browsable format.
- Markdown is a text-to-HTML conversion tool for web writers. Markdown allows you to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid XHTML (or HTML). Thus, “Markdown” is two things: (1) a plain text formatting syntax
- NOTATIONAL VELOCITY is an application that stores and retrieves notes. It is an attempt to loosen the mental blockages to recording information and to scrape away the tartar of convention that handicaps its retrieval. The solution is by nature nonconformist.
- Join the ecosystem. Simplenote replaces the Notes app on your iPhone, iPod touch, or iPad. When you download SImplenote, you get free access to our web app and a variety of desktop apps, so you can access your notes from anywhere. Simplenote just works, and it works fast. You don't need to think about what notes to sync, or when. All you need to do is write, and let Simplenote take care of the rest.
- Computerworld - High-performance computing (HPC) has almost always required a supercomputer — one of those room-size monoliths you find at government research labs and universities. And while those systems aren’t going away, some of the applications traditionally handled by the biggest of Big Iron are heading to the desktop. One reason is that processing that took an hour on a standard PC about eight years ago now takes six seconds, according to Ed Martin, a manager in the automotive unit at computer-aided design software maker Autodesk Inc. Monumental improvements in desktop processing power, graphics processing unit (GPU) performance, network bandwidth and solid-state drive speed combined with 64-bit throughput have made the desktop increasingly viable for large-scale computing projects.

- Giving users more flexibility in how they configure systems to attack various workloads was a big thread running through SC09 last year. At the show, we took at look at three different companies who are, in one way or another, providing large system images. (Click to see our posts on ScaleMP, 3Leaf, and SGI.)

- Engineers, scientists, researchers and other workstation users are continually challenged with more complex problems and shorter deadlines in which to solve them. The Cray CX1-iWS™ solution addresses both of these issues by allowing larger models and simulations to be worked within the workstation environment, eliminating the need to move the problem to an external shared resource cluster, and providing an easy to setup solution.

- Working on a little script the other day I had the need to determine if the input to the script was coming from a pipe or from the terminal. Seems like a simple enough thing to determine but nothing jumped immediately to mind and a quick internet search didn't help much either. After a bit of pondering I came up with two solutions: the stat command and using information from the proc file system.

- NFS is a critical service in many organizations, and even a simple error can lead to major problems. NFSv4 promises to bring several key new features, but clearly it will be imperative to users that the new version of NFS be robust, that it perform well, and that it interoperate easily with other technologies.

- Many enterprise data centers rely on Ethernet for their LAN and data traffic, and on Fibre Channel (FC) networks for their storage infrastructure. With increased adoption of 10GbE in the data center, the availability of Fibre Channel over Ethernet (FCoE), and new lossless 10GbE technologies, it is now possible to consolidate FC SAN storage data flows with LAN and data traffic onto the same unified Ethernet cable. Network convergence will enable enterprises to preserve their existing investments in FC storage, reduce data center costs and complexity, and simplify network management.

- Universal storage connectivity for your existing servers and storage devices. The Data Transport Processor (DTP) routes disk and tape SCSI commands, and the associated block data transfers, between servers and storage devices that have SCSI, FibreChannel, or TCP/IP (iSCSI) interfaces. The DTP can be cabled to a server's SCSI adapter (as a Target), and to SCSI Disk Arrays or Tape Libraries (as an Initiator), AND to a FibreChannel HBA (point-to-point), or to a FC-Arbitrated Loop, or to a FC switch, AND to an Ethernet NIC, or switch. That is, the DTP allows you to connect ANY of your existing servers, whether they are SCSI-cabled, FibreChannel-cabled, or Ethernet-cabled (iSCSI) to ANY of your existing SCSI-command disk and tape devices, whether SCSI-cabled or FibreChannel-cabled or Ethernet-cabled (iSCSI).
- AlfaEbooks allows you quickly scan your computer to find ebooks. You can select specific folders on your PC and file types. AlfaEbooks will automatically detect books, extract ISBN and create a book list that you can check, update and save to the database. It will also find duplicates if found file already exists in the database. You can also use this powerful tool to actualize your e-library when you move books to another drive or DVD.
- Alert Manager was created to run a (alert) command, monitor the status of that command's output, and guarantee that if something goes wrong it won't go unnoticed. Alert Manager has been successfully deployed in several fortune 500 companies providing guaranteed alert delivery and command execution. It has a very flexable configuration file that allows creation of "alert chains" - chains of commands, each with their own fallback command, failure command, timeout, retry counter, and other advanced options. It has a method for passing messages from the command line into the various commands defined in the configuration file and many other useful features. Alert Manager is licensed under the GPL.
- Logdog is a tool that monitors messages passing through syslogd and takes action based on key words and phrases. Logdog has a configuration file which allows you to specify a list of key words or phrases to alert on, and a list of commands that can be run when those words are encountered. Logdog is licensed under the GPL.

- Summary: Vimscript provides excellent support for operating on collections of data, a cornerstone of programming. In this third article in the series, learn how to use Vimscript's built-in lists to ease everyday operations such as reformatting lists, filtering sequences of filenames, and sorting sets of line numbers. You'll also walk through examples that demonstrate the power of lists to extend and enhance two common uses of Vim: creating a user-defined function to align assignment operators, and improving the built-in text completions mechanism.

- Mathematics, rightly viewed, possesses not only truth, but supreme beautya beauty cold and austere, like that of sculpture, without appeal to any part of our weaker nature, without the gorgeous trappings of painting or music, yet sublimely pure, and capable of a stern perfection such as only the greatest art can show. The true spirit of delight, the exaltation, the sense of being more than Man, which is the touchstone of the highest excellence, is to be found in mathematics as surely as in poetry.
- A Performance Comparison of NFS and iSCSI for IP-Networked Storage
- Data sharing is a must in today's modern computing world. When the data requirements include allowing a cluster of servers to access a common storage pool, Red Hat GFS is the answer for simplifying your data infrastructure, minimizing storage costs, adding storage on the fly, and achieving maximum uptime. A cluster file system like Red Hat GFS can be used with an IP network block-sharing protocol like iSCSI to provide scalable file serving at low cost. Network File System (NFS) is a common shared storage solution utilized by many infrastructures. However, in some instances, this solution does not scale. How do GFS and NFS compare? This article explains.

- As computers become more powerful, they are better able to provide answers to increasingly complex scientific questions. Unfortunately, answering these questions comes with significant costs: scientists become intimately familiar with hardware platforms, learn specialized languages and data formats to efficiently represent results, and actively shepherd their simulation runs to identify and correct potential problems as early as possible. In practice, this means computational scientists spend significantly more time managing their data and babysitting their runs rather than doing science.
