Why Did We Choose Freebsd?
Why Did We Choose FreeBSD? Index Why FreeBSD in General? Why FreeBSD Rather than Linux? Why FreeBSD Rather than Windows? Why Did we Choose FreeBSD in General? We are using FreeBSD version 6.1. Here are some more specific features which make it appropriate for use in an ISP environment: Very stable, especially under load as shown by long-term use in large service providers. FreeBSD is a community-supported project which you can be confident is not going to 'go commercial' or start charging any license fees. A single source tree which contains both the kernel and all the rest of the code needed to build a complete base system. Contrast with Linux that has one kernel but hundreds of distributions to choose from, and which may come and go over time. Scalability features as standard: e.g. pwd.db (indexed password database), which give you much better performance and scales well for very large sites. Superior TCP/IP stack that responds well to extremely heavy load. Multiple firewall packages built in to the base system (IPF, IPFW, PF). High-end debugging and tracing tools, including the recently announced port of the Sun Dynamic Tracing tool, DTrace, to FreeBSD. Ability to gather fine-grained statistics on system performance using many included utilities like systat, gstat, iostat, di, swapinfo, disklabel, etc. Items such as software RAID are supported using multiple utilities (ata, ccd. vinum, geom). RAID-1 using GEOM Mirror (see gmirror) supports identical disk sets, or identical disk slieces. Take a look at the most stable web sites according to NetCraft (http://news.netcraft.com/archives/2006/06/06/six_hosting_companies_most_reliable_hoster_in_may.html). -

Dynamic Extension of Typed Functional Languages
Dynamic Extension of Typed Functional Languages Don Stewart PhD Dissertation School of Computer Science and Engineering University of New South Wales 2010 Supervisor: Assoc. Prof. Manuel M. T. Chakravarty Co-supervisor: Dr. Gabriele Keller Abstract We present a solution to the problem of dynamic extension in statically typed functional languages with type erasure. The presented solution re- tains the benefits of static checking, including type safety, aggressive op- timizations, and native code compilation of components, while allowing extensibility of programs at runtime. Our approach is based on a framework for dynamic extension in a stat- ically typed setting, combining dynamic linking, runtime type checking, first class modules and code hot swapping. We show that this framework is sufficient to allow a broad class of dynamic extension capabilities in any statically typed functional language with type erasure semantics. Uniquely, we employ the full compile-time type system to perform run- time type checking of dynamic components, and emphasize the use of na- tive code extension to ensure that the performance benefits of static typing are retained in a dynamic environment. We also develop the concept of fully dynamic software architectures, where the static core is minimal and all code is hot swappable. Benefits of the approach include hot swappable code and sophisticated application extension via embedded domain specific languages. We instantiate the concepts of the framework via a full implementation in the Haskell programming language: providing rich mechanisms for dy- namic linking, loading, hot swapping, and runtime type checking in Haskell for the first time. We demonstrate the feasibility of this architecture through a number of novel applications: an extensible text editor; a plugin-based network chat bot; a simulator for polymer chemistry; and xmonad, an ex- tensible window manager. -

Using Red Hat Client with Netapp Storage Over NFS Bikash Roy Choudhury, Netapp October 2013 | TR-3183
Technical Report Using Red Hat Client with NetApp Storage over NFS Bikash Roy Choudhury, NetApp October 2013 | TR-3183 Abstract This report helps you to get the best from your Linux® NFS clients when used in an environment that includes NetApp® storage. Most of the discussion revolves around Red Hat Enterprise (RHEL) clients. This document does not include best practices and recommendations for block protocols like FCP and iSCSI. The paper highlight some of the best practices and tuning parameters that would be required for running user home directories and regular UNIX® file systems. The paper describes various tuning options on RHEL clients and diagnoses performance and reliability problems. Every workload has a different access pattern and characterization; we recommend appropriate tuning on RHEL clients based on the workload characterization, which should not be treated as “one size fits all" for all workloads. Separate technical reports have been published for different applications that provide recommendations for specific workloads. In this paper you will learn where to look for more information when faced with problems that are d ifficult to diagnose. Storage tuning information specific to your application may be available in other NetApp technical reports and solution guides.
