Access Thousands of R Statistics Packages from F# 3.0

AddThis Social Bookmark Button
Did you know you can use F# type providers to access thousands of statistical packages from R, with auto-complete and documentation? Those of you into data analysis will be aware of the use of the R system by statisticians and other data workers. The F# community and BlueMountain Capital have created a type provider for F#-R interop which embeds all installed R packages directly into F#, with intellisense.  See the  example below.  This demonstrates the great flexibility and applicability of the F# 3.0 type provider mechanism, for interoperating with everything from internet-scale information services to traditional SQL programming to
interoperating with other programming environments.    You can also join in the fun and contribute/fork the project on GitHub. Don Announcing the F# R Type Provider August 1, 2012 at 2:52 pm Here at BlueMountain we like to perform statistical analysis of data.  The stats package R is great for doing that.  We also like to use the data retrieval and processing capabilities of F#. F#’s interactive environment lends itself pretty well to data exploration, and we can also easily access our existing .NET-based libraries.  Once we are done, we can build and release production-supportable applications. Nothing on the .NET platform competes with...(Read whole news on source site)

This is the HTML:
  • Hello
  • World
The question was how to get the hello text out of the first list item only with JavaScript code and in two different ways....(Read whole news on source site)

How To Talk To Employees

Today on Twitter, I noticed this tweet from Dare Obasanjo (aka @carnage4life on Twitter) critical of a blog post by Rand Fishkin, co-founder and CEO of SEOMoz. Why you shouldnt take lessons from inexperienced managers. Replaces to-the-point email with lengthy BS no one'll read - Dare is one of those folks who is very thoughtful in what he blogs and tweets. Most of what he posts is worthwhile, so naturally I clicked through and

In the post, Rand poses a hypothetical scenario (emphasis mine): For example, let’s say Company X has been having trouble with abuse of work-from-home privileges. Managers are finding that more and more people are getting less accomplished and a primary suspect is a lack of coming into the office*. The problem is circulated at the executive team meeting and a decision is made to change the work-from-home policy to provide greater analytics and visibility. An email is sent to the team that looks like this: Rand supplies...(Read whole news on source site)

Attack Surface Analyzer 1.0

AddThis Social Bookmark Button
we released a beta version of our free Attack Surface Analyzer tool. 

The purpose of this tool is to help software developers, Independent Software Vendors (ISVs) and IT Professionals better understand changes in Windows systems’ attack surface resulting from the installation of new applications. 

The Attack Surface Analyzer tool is designed to assist independent software vendors (ISVs) and other software developers during the verification phase of the Microsoft Security Development Lifecycle (SDL) as they evaluate the changes their software makes to the attack surface of a computer.  Because Attack Surface Analyzer does not require
source code or symbol access, IT professionals and security auditors can also use the tool to gain a better understanding of the aggregate attack surface change that may result from the introduction of line-of-business (LOB) applications to the Windows platform.

Sometime back I had the opportunity to explore the possibility of using Webservers other than IIS (Internet Information Services) for an ASP.NET based website. It was at this time I came across the other possible web servers like IISExpress and Cassini. Both were quite new to me when I started reading about them but eventually, I got well rounded experience in deploying the application on these web servers. Below a Read More....
