  • Leaving Microsoft

    - by Stephen Walther
    After two and a half years working with the ASP.NET team, I’ve decided that this is the right time to leave Microsoft and, with the help of some friends, re-launch my ASP.NET training and consulting company. The company has the modest name Superexpert. While working on my Ph.D. at MIT, I was surrounded by professors and students who were passionate about knowledge. During the Internet boom, I was lucky enough to work side-by-side with some very smart and hard-working people to create several successful startups. However, the people I worked with at Microsoft were among the smartest and hardest working. Microsoft hires a small number of people and gives them huge responsibilities. It continues to amaze me that so few people work on the ASP.NET team when you consider how much the team produces. I had the opportunity to work with a number of inspiring people at Microsoft. I’ll miss working with Scott Hunter, Dave Reed, Boris Moore, Eilon Lipton, Scott Guthrie, James Senior, Jim Wang, Phil Haack, Damian Edwards, Vishal Joshi, Mike Pope, Jon Young, Dmitry Robsman, Simon Calvert, Stefan Schackow, and many others. I’m proud of what we accomplished while I was working at Microsoft. We reached out to the jQuery team and changed direction from Microsoft Ajax to jQuery. We successfully contributed several important new features to the open-source jQuery project including jQuery Templates, jQuery Data-Linking, jQuery Globalization, and (as John Resig announced at the last jQuery conference) jQuery Require. I’m looking forward to returning to training and consulting. We want to focus on providing consulting on the “right way” of building ASP.NET websites, which we call Modern ASP.NET applications. By Modern ASP.NET applications, I mean applications built with ASP.NET MVC, jQuery, HTML5, and Visual Studio ALM. Additionally, we want to help companies that have existing ASP.NET Web Forms applications migrate to ASP.NET MVC. If you are interested in having us provide training for your company or you need help building a custom ASP.NET application then please contact us at [email protected] or visit our website at Superexpert.com.

  • Oracle OpenWorld Live 2012 Videos

    - by Chris Kawalek
    The Oracle virtualization team is back from a very successful Oracle OpenWorld! Hopefully you were able to come to the show and talk with our virtualization experts at the demo booths or in our sessions. But if you didn't, you can get a summary of what we talked about from a number of short videos. In this post, we're going to highlight the Oracle OpenWorld Live videos, and in a future post we'll cover the videos we shot ourselves (once we get them all posted!). If you missed it, Oracle OpenWorld Live carried keynotes and interviews with all kinds of folks during the show. They also archived these segments so you can watch them at your leisure. I've gone through the videos and selected some that highlight virtualization: Edward Screven on mission critical clouds. Wim Coekaerts talks virtualization. Rex Wang on Oracle Cloud. Ronen Kofman on Oracle VM Templates. Chris Kawalek on Oracle's desktop virtualization software. Chris Kawalek discusses Oracle Sun Ray Clients. If we missed you this year, we hope to see you at OpenWorld 2013! -Chris

  • LASTDATE dates arguments and upcoming events #dax #tabular #powerpivot

    - by Marco Russo (SQLBI)
    Recently I had to write a DAX formula containing a LASTDATE within the logical condition of a FILTER: I found that its behavior was not the one I expected and I further investigated. At the end, I wrote my findings in this article on SQLBI, which can be applied to any Time Intelligence function with a <dates> argument.The key point is that when you write LASTDATE( table[column] )in reality you obtain something like LASTDATE( CALCULATETABLE( VALUES( table[column] ) ) )which converts an existing row context into a filter context.Thus, if you have something like FILTER( table, table[column] = LASTDATE( table[column] ) the FILTER will return all the rows of table, whereas you probably want to use FILTER( table, table[column] = LASTDATE( VALUES( table[column] ) ) )so that the existing filter context before executing FILTER is used to get the result from VALUES( table[column] ), avoiding the automatic expansion that would include a CALCULATETABLE that would hide the existing filter context.If after reading the article you want to get more insights, read the Jeffrey Wang's post here.In these days I'm speaking at SQLRally Nordic 2012 in Copenhagen and I will be in Cologne (Germany) next week for a SSAS Tabular Workshop, whereas Alberto will teach the same workshop in Amsterdam one week later. Both workshops still have seats available and the Amsterdam's one is still in early bird discount until October 3rd!Then, in November I expect to meet many blog readers at PASS Summit 2012 in Seattle and I hope to find the time to write other article on interesting things on Tabular and PowerPivot. Stay tuned!

  • Getting-started: Setup Database for Node.js

    - by Emile Petrone
    I am new to node.js but am excited to try it out. I am using Express as a web framework, and Jade as a template engine. Both were easy to get setup following this tutorial from Node Camp. However the one problem I am finding is I can't find a simple tutorial for getting a DB set up. I am trying to build a basic chat application (store session and message). Does anyone know of a good tutorial? This other SO post talks about dbs to use- but as this is very different from the Django/MySQL world I've been in, I want to make sure I understand what is going on. Thanks!

  • Getting started with Express - Error: Cannot find module './routes'

    - by Enrico Tuttobene
    I am just getting started in the world of Node.JS, and I tried using the command line "express" command to install a basic application (with jade support) Now, I was playing around with it a bit to see how it works and I am coming across a strange error: In the /routes directory there is a file called index which contains exports.index = function(req, res){ res.render('index', { title: "Express" }); }; that, as you all know, renders the index page. Well, all I did was renaming that file from index.js to router.js, so that I can easily refer to it as I would like to have more than just an index page. The renaming doesn't work, I get the error Error: Cannot find module './routes' Which is weird, as I though that var express = require('express'), routes = require('./routes'); would require ALL the files in the directory. There must be something small there I'm missing, and please bare with me as I am pretty new to this. Thanks in advance.

  • Interview question: difference between object and object-oriented languages.

    - by Bar
    My friend was asked the following question: what's the difference between object language and object-oriented language? It's a little unintelligible question. What does term «object language» correspond to? Does that mean «pure» object-oriented language, like the Wikipedia article says: Languages called "pure" OO languages, because everything in them is treated consistently as an object, from primitives such as characters and punctuation, all the way up to whole classes, prototypes, blocks, modules, etc. They were designed specifically to facilitate, even enforce, OO methods. Examples: Smalltalk, Eiffel, Ruby, JADE, VB.NET.

  • how to parse a Date string to java.Date

    - by hguser
    Hi: I have a date string and I wang to parse it to normal date use the java Date API,the following is my code: public static void main(String[] args) { String date="2010-10-02T12:23:23Z"; String pattern="yyyy-MM-ddThh:mm:ssZ"; SimpleDateFormat sdf=new SimpleDateFormat(pattern); try { Date d=sdf.parse(date); System.out.println(d.getYear()); } catch (ParseException e) { // TODO Auto-generated catch block e.printStackTrace(); } } However I got a exception:java.lang.IllegalArgumentException: Illegal pattern character 'T' So I wonder if i have to split the string and parse it manually? BTW, I have tried to add a single quote character on either side of the T: String pattern="yyyy-MM-dd'T'hh:mm:ssZ"; It also does not work.

  • IIS 6 session timing out a lot quicker than expected

    - by Echiban
    I am working with an web application that has its sessions timing out a lot quicker than expected. We expected a timeout of 15 minutes but it's timing out at 3-4 minutes. Info about environment: IIS6 classic ASP / COM+ app timeout OK on current PROD, much quicker in dev / QA environments We already disabled app pool recycling, and even put IIS in isolation mode - no effect HTTP err log doesn't display any lines when session times out We've done a close comparison of PROD and DEV / QA environments, and given we use virtual machines on all of them, settings should be preserved. I tried to find IIS blog notes from David Wang but many of them now have HTTP 404 errors, and I don't know what else to do. Please help! At the very least, is there a way to get IIS to log every time a session expires? At the very least some means of logging / debugging IIS would be useful. Thanks in advance.

  • The Social Business Thought Leaders

    - by kellsey.ruppel
    Enterprise Gamification, Big Data, Social Support, Total Customer Experience, Pull Organizations, Social Business. Are these purely the latest buzzwords to enter the market or significant trends that companies should keep an eye on? Oracle recently sponsored and presented at the 5th Social Business Forum, one of the largest European events on the use of social media as a business tool and accelerator. Through the participation of dozens of practitioners, experts and customer success stories, the conference demonstrated how a perfect storm of technology, management and cultural change is pushing peer-to-peer conversations deep into business processes. It is clear that Social Business is serving as a new propellant of agility, efficiency and reactivity. According to Deloitte and MIT what we have learned to call Social Business is considered important in the next 3 years by 86% of managers (see Social Business: What Are Companies Really Doing?, MIT Sloan Management Review and Deloitte). McKinsey further estimates the value that can be unlocked in terms of knowledge-worker productivity, consumer insights, product co-creation, improved sales, marketing and customer service up to $1300B (See The social economy: Unlocking value and productivity through social technologies, McKinsey Global Institute). This impacts any industry, with the strongest effects seen in Media & Entertainment, Technology, Telcos and Education. For those not able to attend the Social Business Forum and also for the many friends that joined us in Milan, we decided to keep the conversation going by extracting some golden nuggets from the perspective of five of the most well-known thought-leaders in this space. Starting this week you will have the chance to view: John Hagel (Author of the Power of Pull and Co-Chairman Center for the Edge at Deloitte & Touche) Christian Finn (Senior Director, WebCenter Evangelist at Oracle) Steve Denning (Author of The Radical Management and Independent Management Consulting Professional) Esteban Kolsky (Principal & Founder at ThinkJar) Ray Wang (Principal Analyst & CEO at Constellation Research) Stay tuned to hear: How pull organizations are addressing some of the deepest challenges impacting the market. How to integrate social into existing infrastructure and processes. How to apply radical management to become more agile and profitable. About the importance of gamification as an engagement lever. The first interview with John Hagel will be published tomorrow. Don't miss it and the entire series!

  • COM+/Desktop Heap errors in IIS affecting sites at random?

    - by tresstylez
    We have a Win2K3 server that is hosting 30+ sites. Each site is configured to have its own unique application pool -- so that we can manually recycle specific sites if needed and not kill sessions for the others. From what I've read, the consequence of this type of setup is that each application pool worker process gets allocated a Desktop Heap (normally 512 kb's) and we limit the number of app pools we can serve. http://blogs.msdn.com/b/david.wang/archive/2006/01/25/security-considerations-of-usesharedwpdesktop-on-iis6.aspx PROBLEM: What we're seeing is that occasionally COM+ errors get triggered, presumably by hitting our 512 kb limit of the desktop heap -- and certain sites become unresponsive (or have errors) until we manually recycle that specific app pool. I know that I can increase the desktop heap limit to 1024, and make other tweaks/tunes, but I've been tasked with finding out what exactly causes one site's heap to max out as opposed to another. It seems that when we start seeing COM+ errors, the sites it affects are random -- small sites or big sites (heavier used). Is it based on process id? Traffic? Any pointers on understanding this a little more would be excellent. Thanks! jg

  • Is F# a good language for card game AI?

    - by Anthony Brien
    I'm writing a Mahjong Game in C# (the Chinese traditional game, not the solitaire kind). While writing the code for the bot player's AI, I'm wondering if a functional language like F# would be a more suitable language than what I currently use which is C# with a lot of Linq. I don't know much about F# which is why I ask here. To illustrate what I try to solve, here's a quick summary of Mahjong: Mahjong plays a bit like Gin Rummy. You have 13 tiles in your hand, and each turn, you draw a tile and discard another one, trying to improve your hand towards a winning Mahjong hand, which consists or 4 sets and a pair. Sets can be a 3 of a kind (pungs), 4 of a kind (kongs) or a sequence of 3 consecutive tiles (chows). You can also steal another player's discard, if it can complete one of your sets. The code I had to write to detect if the bot can declare 3 consecutive tiles set (chow) is pretty tedious. I have to find all the unique tiles in the hand, and then start checking if there's a sequence of 3 tiles that contain that one in the hand. Detecting if the bot can go Mahjong is even more complicated since it's a combination of detecting if there's 4 sets and a pair in his hand. And that's just a standard Mahjong hand. There's also numerous "special" hands that break those rules but are still a Mahjong hand. For example, "13 unique wonders" consists of 13 specific tiles, "Jade Empire" consists of only tiles colored green, etc. In a perfect world, I'd love to be able to just state the 'rules' of Mahjong, and have the language be able to match a set of 13 tiles against those rules to retrieve which rules it fulfills, for example, checking if it's a Mahjong hand or if it includes a 4 of a kind. Is this something F#'s pattern matching feature can help solve?

  • How to store session values with Node.js and mongodb?

    - by Tirithen
    How do I get sessions working with Node.js, [email protected] and mongodb? I'm now trying to use connect-mongo like this: var config = require('../config'), express = require('express'), MongoStore = require('connect-mongo'), server = express.createServer(); server.configure(function() { server.use(express.logger()); server.use(express.methodOverride()); server.use(express.static(config.staticPath)); server.use(express.bodyParser()); server.use(express.cookieParser()); server.use(express.session({ store: new MongoStore({ db: config.db }), secret: config.salt })); }); server.configure('development', function() { server.use(express.errorHandler({ dumpExceptions: true, showStack: true })); }); server.configure('production', function() { server.use(express.errorHandler()); }); server.set('views', __dirname + '/../views'); server.set('view engine', 'jade'); server.listen(config.port); I'm then, in a server.get callback trying to use req.session.test = 'hello'; to store that value in the session, but it's not stored between the requests. It probobly takes something more that this to store session values, how? Is there a better documented module than connect-mongo?

  • A Forming Repository of Script Samples for Automating Windows Server 2012 and Windows 8

    - by Jialiang
    Compared with Windows Server 2008/R2 that provides about 230 cmdlets, Windows Server 2012 beats that by a factor of over 10 shipping ~ 2,430 cmdlets.  You can automate almost every aspect of the server.   The new PowerShell 3.0, like Windows Server 2012, has a ton of new features.  In this automation script-centric move, Microsoft All-In-One Script Framework (AIOSF) is ready to support IT Pros with many new services and offerings coming this year.  We sincerely hope that the IT community will benefit from the effort. Here is the first one among our new services and offerings:  The team is preparing a large set of Windows 8 / Windows Server 2012 script samples based on frequently asked IT tasks that we collect in TechNet forums and support calls to Microsoft.   Because the script topics come from frequently asked IT tasks, we hope that these script samples can be helpful to many IT Pros worldwide.   With the General Availability of Windows Server 2012, we release the first three Windows Server 2012 / Windows 8 script samples today.    Get Network Adapter Properties in Windows Server 2012 and Windows 8 (PowerShell) http://gallery.technet.microsoft.com/scriptcenter/Get-Network-Adapter-37c5a913 Description: This script could be used to get network adapter properties and advanced properties in Windows Server 2012 and Windows 8. It combines the outputs of Get-NetAdapter and Get-NetAdapterAdvancedProperty. It can generate a report of network adapter configuration settings. Use Scenarios: In a real world, IT Administrators are required to check the configuration of network adapters after the deployment of new servers. One typical example is the duplex setting of network adapters. Also, IT administrators need to maintain a server list which contains network adapter configuration settings in a regular basis. Before Windows Server 2012, IT administrators often feel difficulties to handle these tasks. Acknowledgement: Thanks Greg Gu from AIOSF for collecting this script topic, and writing the script sample.  Thanks James Adams (Microsoft Premier Field Engineer) for reviewing the script sample and ensuring its quality.   How to batch create virtual machines in Windows Server 2012 (PowerShell) http://gallery.technet.microsoft.com/scriptcenter/How-to-batch-create-9efd1811 Description: This PowerShell Script illustrates how to batch create multiple virtual machines based on comma delimited file by using PowerShell 3.0 in Windows Server 2012. Use Scenarios: IT admin requires to batch creating virtual machines in Windows Server 2012, although they can use few commands due to the lack of programming knowledge. Although it’s a set of Hyper-V command-lets within Windows PowerShell, IT Admins are reluctant to use them except simple a command which is widely used. Acknowledgement: Thanks Anders Wang from AIOSF for collecting this script topic and writing the script sample.  Thanks Christopher Norris for reviewing the script sample and ensuring its quality before publishing.   Remove Windows Store Apps in Windows 8 (PowerShell) http://gallery.technet.microsoft.com/scriptcenter/Remove-Windows-Store-Apps-a00ef4a4 Description: This script can be used to remove multiple Windows Store Apps from a user account in Windows 8. It provides a list of installed Windows Store applications. You can specify the application IDs, and remove them all at once. Use Scenarios: 1. In Windows 8, you can remove a single Windows Store App by right-clicking the tile in the Start menu and choosing the uninstall command.  However, no command is provided for removing multiple Windows Store Apps all at once. If you want to do so, you can use this script sample. 2. Sometimes Windows Store Apps may crash in Windows 8.  Even though you can successfully uninstall and reinstall the App, the application may still crash after the reinstallation.  In this situation, you can use this example script to remove these Windows Store Apps cleanly. Acknowledgement: Thanks Edward Qi from AIOSF for collecting the script idea and composing the script sample.  Thanks James Adams (Microsoft Premier Field Engineer) for reviewing the script sample and ensuring its quality.   This is just the beginning, and more and more script samples are coming.  You can follow our blog (http://blogs.technet.com/b/onescript) to get the latest customer-driven script samples for Windows Server 2012 and Windows 8.

This topic continues generating widespread discussion around how we connect with businesses, employers, governments, and extended social communities across multiple channels spanning web, mobile and human face to face contact. Earlier in our Social Business Thought Leader Webcast Series, we had AIIM President John Mancini presenting "Moving from Records to Engagement to Insight" discussing the factors that are driving organizations to think more strategically about the intersection of content management, social technologies, and business processes. John spoke about how Content Management and Enterprise IT are being changed by social technologies and how new technologies are being used to drive innovation and transform processes along and what the implications of this transformation are for information professionals. He used these two slides below to illustrate the evolution from Systems of Record to Systems of Engagement. The AIIM White Paper is available for download from the AIIM website. Later this week (09/20), we'll have another session in our Social Business Thought Leader Webcast Series featuring  R “Ray” Wang (@rwang0) Principal Analyst & CEO from Constellation Research presenting: "Engaging Customers in the Era of Overexposure"  More info to come tomorrow on the upcoming webcast this week. ~~~~~~ In the spirit of spreading good karma - one of the first things that came to mind as I was thinking about "Engagement" was the evolution of the Marriage Proposal.  Someone sent me a link to this link a couple of months ago and it raises the bar on all proposals. I hope you'll enjoy!

  • Deploying ASP.NET MVC to IIS6: pages are just blank

    - by BryanGrimes
    I have an MVC app that is actually on a couple other servers but I didn't do the deploy. For this deploy I have added the wildcard to aspnet_isapi.dll which has gotten rid of the 404 error. But the pages are not pulling up, rather everything is just blank. I can't seem to find any IIS configuration differences. The Global asax.cs file does have routing defined, but as I've seen on a working server, that file isn't just hanging out in the root or anything so obvious. What could I be missing here? All of the servers are running IIS6 and I have compared the setups and they look the same to me at this point. Thanks... Bryan EDIT for the comments thus far: I've looked in the event logs with no luck, and scoured various IIS logs per David Wang: blogs.msdn.com. Below is the Global.asax.cs file... public class MvcApplication : System.Web.HttpApplication { public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.IgnoreRoute("error.axd"); // for Elmah // For deployment to IIS6 routes.Add(new Route ( "{controller}.mvc/{action}/{id}", new RouteValueDictionary(new { action = "Index", id = (string)null }), new MvcRouteHandler() )); routes.MapRoute( "WeeklyTimeSave", "Time/Save", new { controller = "Time", action = "Save" } ); routes.MapRoute( "WeeklyTimeAdd", "Time/Add", new { controller = "Time", action = "Add" } ); routes.MapRoute( "WeeklyTimeEdit", "Time/Edit/{id}", new { controller = "Time", action = "Edit", id = "" } ); routes.MapRoute( "FromSalesforce", "Home/{id}", new { controller = "Home", action = "Index", id = "" }); routes.MapRoute( "Default2", "{controller}/{id}", new { controller = "Home", action = "Index", id = "" } ); routes.MapRoute( "Default", "{controller}/{action}/{id}", new { controller = "Home", action = "Index", id = "" } ); } protected void Application_Start() { RegisterRoutes(RouteTable.Routes); } } Maybe this is as stupid as the asax file not being somewhere it needs to be, but heck if I know at this point.

  • String Manipulation in C

    - by baris_a
    Hi guys, I am helping my nephew for his C lab homework, it is a string manipulation assignment and applying Wang's algorithm. Here is the BNF representation for the input. <sequent> ::= <lhs> # <rhs> <lhs> ::= <formulalist>| e <rhs> ::= <formulalist>| e <formulalist> ::= <formula>|<formula> , <formulalist> <formula> ::= <letter>| - <formula>| (<formula><in?xop><formula>) <in?xop> ::= & | | | > <letter> ::= A | B | ... | Z What is the best practice to handle and parse this kind of input in C? How can I parse this structure without using struct? Thanks in advance.

  • Body Mass Index program in haskell

    - by user364996
    Hi there. I'm trying to write a simple program in Haskell that can determine someone's body mass index. Here's what I have written: type Height = Float type Weight = Float type PeopleStats = [(String, Height, Weight)] and... bmi :: Height -> Weight -> Float bmi heightCm weightKg = weightKg/(heightCm)^2 healthy :: Height -> Weight -> Bool healthy heightCm weightKg | 25 > index && 18 < index = True | otherwise = False where index = bmi heightCm weightKg So far, the function "healthy" can calculate someone's BMI, and the function "healthyPeople" returns a boolean statement determining if the person's BMI falls within the limits which is considered normal for a healthy person. I want to write a function called "healthyPeople". healthyPeople :: PeopleStats -> [String] This function needs to take a list of PeopleStats and returns a list of names (Strings) of people who are deemed to be "healthy" from the "healthy" function. For example: If I input [("Lee", 65, 185), ("Wang", 170, 100), ("Tsu", 160, 120)] I will get a list of the names of the people whose BMI returns true form the boolean function in "healthy". Please help !!!!

  • CDN on Hosted Service in Windows Azure

    - by Shaun
    Yesterday I told Wang Tao, an annoying colleague sitting beside me, about how to make the static content enable the CDN in his website which had just been published on Windows Azure. The approach would be Move the static content, the images, CSS files, etc. into the blob storage. Enable the CDN on his storage account. Change the URL of those static files to the CDN URL. I think these are the very common steps when using CDN. But this morning I found that the new Windows Azure SDK 1.4 and new Windows Azure Developer Portal had just been published announced at the Windows Azure Blog. One of the new features in this release is about the CDN, which means we can enabled the CDN not only for a storage account, but a hosted service as well. Within this new feature the steps I mentioned above would be turned simpler a lot.   Enable CDN for Hosted Service To enable the CDN for a hosted service we just need to log on the Windows Azure Developer Portal. Under the “Hosted Services, Storage Accounts & CDN” item we will find a new menu on the left hand side said “CDN”, where we can manage the CDN for storage account and hosted service. As we can see the hosted services and storage accounts are all listed in my subscriptions. To enable a CDN for a hosted service is veru simple, just select a hosted service and click the New Endpoint button on top. In this dialog we can select the subscription and the storage account, or the hosted service we want the CDN to be enabled. If we selected the hosted service, like I did in the image above, the “Source URL for the CDN endpoint” will be shown automatically. This means the windows azure platform will make all contents under the “/cdn” folder as CDN enabled. But we cannot change the value at the moment. The following 3 checkboxes next to the URL are: Enable CDN: Enable or disable the CDN. HTTPS: If we need to use HTTPS connections check it. Query String: If we are caching content from a hosted service and we are using query strings to specify the content to be retrieved, check it. Just click the “Create” button to let the windows azure create the CDN for our hosted service. The CDN would be available within 60 minutes as Microsoft mentioned. My experience is that about 15 minutes the CDN could be used and we can find the CDN URL in the portal as well.   Put the Content in CDN in Hosted Service Let’s create a simple windows azure project in Visual Studio with a MVC 2 Web Role. When we created the CDN mentioned above the source URL of CDN endpoint would be under the “/cdn” folder. So in the Visual Studio we create a folder under the website named “cdn” and put some static files there. Then all these files would be cached by CDN if we use the CDN endpoint. The CDN of the hosted service can cache some kind of “dynamic” result with the Query String feature enabled. We create a controller named CdnController and a GetNumber action in it. The routed URL of this controller would be /Cdn/GetNumber which can be CDN-ed as well since the URL said it’s under the “/cdn” folder. In the GetNumber action we just put a number value which specified by parameter into the view model, then the URL could be like /Cdn/GetNumber?number=2. 1: using System; 2: using System.Collections.Generic; 3: using System.Linq; 4: using System.Web; 5: using System.Web.Mvc; 6:  7: namespace MvcWebRole1.Controllers 8: { 9: public class CdnController : Controller 10: { 11: // 12: // GET: /Cdn/ 13:  14: public ActionResult GetNumber(int number) 15: { 16: return View(number); 17: } 18:  19: } 20: } And we add a view to display the number which is super simple. 1: <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<int>" %> 2:  3: <asp:Content ID="Content1" ContentPlaceHolderID="TitleContent" runat="server"> 4: GetNumber 5: </asp:Content> 6:  7: <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> 8:  9: <h2>The number is: <% 1: : Model.ToString() %></h2> 10:  11: </asp:Content> Since this action is under the CdnController the URL would be under the “/cdn” folder which means it can be CDN-ed. And since we checked the “Query String” the content of this dynamic page will be cached by its query string. So if I use the CDN URL, http://az25311.vo.msecnd.net/GetNumber?number=2, the CDN will firstly check if there’s any content cached with the key “GetNumber?number=2”. If yes then the CDN will return the content directly; otherwise it will connect to the hosted service, http://aurora-sys.cloudapp.net/Cdn/GetNumber?number=2, and then send the result back to the browser and cached in CDN. But to be notice that the query string are treated as string when used by the key of CDN element. This means the URLs below would be cached in 2 elements in CDN: http://az25311.vo.msecnd.net/GetNumber?number=2&page=1 http://az25311.vo.msecnd.net/GetNumber?page=1&number=2 The final step is to upload the project onto azure. Test the Hosted Service CDN After published the project on azure, we can use the CDN in the website. The CDN endpoint we had created is az25311.vo.msecnd.net so all files under the “/cdn” folder can be requested with it. Let’s have a try on the sample.htm and c_great_wall.jpg static files. Also we can request the dynamic page GetNumber with the query string with the CDN endpoint. And if we refresh this page it will be shown very quickly since the content comes from the CDN without MCV server side process. We style of this page was missing. This is because the CSS file was not includes in the “/cdn” folder so the page cannot retrieve the CSS file from the CDN URL.   Summary In this post I introduced the new feature in Windows Azure CDN with the release of Windows Azure SDK 1.4 and new Developer Portal. With the CDN of the Hosted Service we can just put the static resources under a “/cdn” folder so that the CDN can cache them automatically and no need to put then into the blob storage. Also it support caching the dynamic content with the Query String feature. So that we can cache some parts of the web page by using the UserController and CDN. For example we can cache the log on user control in the master page so that the log on part will be loaded super-fast. There are some other new features within this release you can find here. And for more detailed information about the Windows Azure CDN please have a look here as well.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.

  • A New Threat To Web Applications: Connection String Parameter Pollution (CSPP)

    - by eric.maurice
    Hi, this is Shaomin Wang. I am a security analyst in Oracle's Security Alerts Group. My primary responsibility is to evaluate the security vulnerabilities reported externally by security researchers on Oracle Fusion Middleware and to ensure timely resolution through the Critical Patch Update. Today, I am going to talk about a serious type of attack: Connection String Parameter Pollution (CSPP). Earlier this year, at the Black Hat DC 2010 Conference, two Spanish security researchers, Jose Palazon and Chema Alonso, unveiled a new class of security vulnerabilities, which target insecure dynamic connections between web applications and databases. The attack called Connection String Parameter Pollution (CSPP) exploits specifically the semicolon delimited database connection strings that are constructed dynamically based on the user inputs from web applications. CSPP, if carried out successfully, can be used to steal user identities and hijack web credentials. CSPP is a high risk attack because of the relative ease with which it can be carried out (low access complexity) and the potential results it can have (high impact). In today's blog, we are going to first look at what connection strings are and then review the different ways connection string injections can be leveraged by malicious hackers. We will then discuss how CSPP differs from traditional connection string injection, and the measures organizations can take to prevent this kind of attacks. In web applications, a connection string is a set of values that specifies information to connect to backend data repositories, in most cases, databases. The connection string is passed to a provider or driver to initiate a connection. Vendors or manufacturers write their own providers for different databases. Since there are many different providers and each provider has multiple ways to make a connection, there are many different ways to write a connection string. Here are some examples of connection strings from Oracle Data Provider for .Net/ODP.Net: Oracle Data Provider for .Net / ODP.Net; Manufacturer: Oracle; Type: .NET Framework Class Library: - Using TNS Data Source = orcl; User ID = myUsername; Password = myPassword; - Using integrated security Data Source = orcl; Integrated Security = SSPI; - Using the Easy Connect Naming Method Data Source = username/password@//myserver:1521/my.server.com - Specifying Pooling parameters Data Source=myOracleDB; User Id=myUsername; Password=myPassword; Min Pool Size=10; Connection Lifetime=120; Connection Timeout=60; Incr Pool Size=5; Decr Pool Size=2; There are many variations of the connection strings, but the majority of connection strings are key value pairs delimited by semicolons. Attacks on connection strings are not new (see for example, this SANS White Paper on Securing SQL Connection String). Connection strings are vulnerable to injection attacks when dynamic string concatenation is used to build connection strings based on user input. When the user input is not validated or filtered, and malicious text or characters are not properly escaped, an attacker can potentially access sensitive data or resources. For a number of years now, vendors, including Oracle, have created connection string builder class tools to help developers generate valid connection strings and potentially prevent this kind of vulnerability. Unfortunately, not all application developers use these utilities because they are not aware of the danger posed by this kind of attacks. So how are Connection String parameter Pollution (CSPP) attacks different from traditional Connection String Injection attacks? First, let's look at what parameter pollution attacks are. Parameter pollution is a technique, which typically involves appending repeating parameters to the request strings to attack the receiving end. Much of the public attention around parameter pollution was initiated as a result of a presentation on HTTP Parameter Pollution attacks by Stefano Di Paola and Luca Carettoni delivered at the 2009 Appsec OWASP Conference in Poland. In HTTP Parameter Pollution attacks, an attacker submits additional parameters in HTTP GET/POST to a web application, and if these parameters have the same name as an existing parameter, the web application may react in different ways depends on how the web application and web server deal with multiple parameters with the same name. When applied to connections strings, the rule for the majority of database providers is the "last one wins" algorithm. If a KEYWORD=VALUE pair occurs more than once in the connection string, the value associated with the LAST occurrence is used. This opens the door to some serious attacks. By way of example, in a web application, a user enters username and password; a subsequent connection string is generated to connect to the back end database. Data Source = myDataSource; Initial Catalog = db; Integrated Security = no; User ID = myUsername; Password = XXX; In the password field, if the attacker enters "xxx; Integrated Security = true", the connection string becomes, Data Source = myDataSource; Initial Catalog = db; Integrated Security = no; User ID = myUsername; Password = XXX; Intergrated Security = true; Under the "last one wins" principle, the web application will then try to connect to the database using the operating system account under which the application is running to bypass normal authentication. CSPP poses serious risks for unprepared organizations. It can be particularly dangerous if an Enterprise Systems Management web front-end is compromised, because attackers can then gain access to control panels to configure databases, systems accounts, etc. Fortunately, organizations can take steps to prevent this kind of attacks. CSPP falls into the Injection category of attacks like Cross Site Scripting or SQL Injection, which are made possible when inputs from users are not properly escaped or sanitized. Escaping is a technique used to ensure that characters (mostly from user inputs) are treated as data, not as characters, that is relevant to the interpreter's parser. Software developers need to become aware of the danger of these attacks and learn about the defenses mechanism they need to introduce in their code. As well, software vendors need to provide templates or classes to facilitate coding and eliminate developers' guesswork for protecting against such vulnerabilities. Oracle has introduced the OracleConnectionStringBuilder class in Oracle Data Provider for .NET. Using this class, developers can employ a configuration file to provide the connection string and/or dynamically set the values through key/value pairs. It makes creating connection strings less error-prone and easier to manager, and ultimately using the OracleConnectionStringBuilder class provides better security against injection into connection strings. For More Information: - The OracleConnectionStringBuilder is located at http://download.oracle.com/docs/cd/B28359_01/win.111/b28375/OracleConnectionStringBuilderClass.htm - Oracle has developed a publicly available course on preventing SQL Injections. The Server Technologies Curriculum course "Defending Against SQL Injection Attacks!" is located at http://st-curriculum.oracle.com/tutorial/SQLInjection/index.htm - The OWASP web site also provides a number of useful resources. It is located at http://www.owasp.org/index.php/Main_Page

  • Node.js Adventure - Node.js on Windows

    - by Shaun
    Two weeks ago I had had a talk with Wang Tao, a C# MVP in China who is currently running his startup company and product named worktile. He asked me to figure out a synchronization solution which helps his product in the future. And he preferred me implementing the service in Node.js, since his worktile is written in Node.js. Even though I have some experience in ASP.NET MVC, HTML, CSS and JavaScript, I don’t think I’m an expert of JavaScript. In fact I’m very new to it. So it scared me a bit when he asked me to use Node.js. But after about one week investigate I have to say Node.js is very easy to learn, use and deploy, even if you have very limited JavaScript skill. And I think I became love Node.js. Hence I decided to have a series named “Node.js Adventure”, where I will demonstrate my story of learning and using Node.js in Windows and Windows Azure. And this is the first one.   (Brief) Introduction of Node.js I don’t want to have a fully detailed introduction of Node.js. There are many resource on the internet we can find. But the best one is its homepage. Node.js was created by Ryan Dahl, sponsored by Joyent. It’s consist of about 80% C/C++ for core and 20% JavaScript for API. It utilizes CommonJS as the module system which we will explain later. The official definition of Node.js is Node.js is a platform built on Chrome's JavaScript runtime for easily building fast, scalable network applications. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices. First of all, Node.js utilizes JavaScript as its development language and runs on top of V8 engine, which is being used by Chrome. It brings JavaScript, a client-side language into the backend service world. So many people said, even though not that actually, “Node.js is a server side JavaScript”. Additionally, Node.js uses an event-driven, non-blocking IO model. This means in Node.js there’s no way to block currently working thread. Every operation in Node.js executed asynchronously. This is a huge benefit especially if our code needs IO operations such as reading disks, connect to database, consuming web service, etc.. Unlike IIS or Apache, Node.js doesn’t utilize the multi-thread model. In Node.js there’s only one working thread serves all users requests and resources response, as the ST star in the figure below. And there is a POSIX async threads pool in Node.js which contains many async threads (AT stars) for IO operations. When a user have an IO request, the ST serves it but it will not do the IO operation. Instead the ST will go to the POSIX async threads pool to pick up an AT, pass this operation to it, and then back to serve any other requests. The AT will actually do the IO operation asynchronously. Assuming before the AT complete the IO operation there is another user comes. The ST will serve this new user request, pick up another AT from the POSIX and then back. If the previous AT finished the IO operation it will take the result back and wait for the ST to serve. ST will take the response and return the AT to POSIX, and then response to the user. And if the second AT finished its job, the ST will response back to the second user in the same way. As you can see, in Node.js there’s only one thread serve clients’ requests and POSIX results. This thread looping between the users and POSIX and pass the data back and forth. The async jobs will be handled by POSIX. This is the event-driven non-blocking IO model. The performance of is model is much better than the multi-threaded blocking model. For example, Apache is built in multi-threaded blocking model while Nginx is in event-driven non-blocking mode. Below is the performance comparison between them. And below is the memory usage comparison between them. These charts are captured from the video NodeJS Basics: An Introductory Training, which presented at Cloud Foundry Developer Advocate.   Node.js on Windows To execute Node.js application on windows is very simple. First of you we need to download the latest Node.js platform from its website. After installed, it will register its folder into system path variant so that we can execute Node.js at anywhere. To confirm the Node.js installation, just open up a command windows and type “node”, then it will show the Node.js console. As you can see this is a JavaScript interactive console. We can type some simple JavaScript code and command here. To run a Node.js JavaScript application, just specify the source code file name as the argument of the “node” command. For example, let’s create a Node.js source code file named “helloworld.js”. Then copy a sample code from Node.js website. 1: var http = require("http"); 2:  3: http.createServer(function (req, res) { 4: res.writeHead(200, {"Content-Type": "text/plain"}); 5: res.end("Hello World\n"); 6: }).listen(1337, "127.0.0.1"); 7:  8: console.log("Server running at http://127.0.0.1:1337/"); This code will create a web server, listening on 1337 port and return “Hello World” when any requests come. Run it in the command windows. Then open a browser and navigate to http://localhost:1337/. As you can see, when using Node.js we are not creating a web application. In fact we are likely creating a web server. We need to deal with request, response and the related headers, status code, etc.. And this is one of the benefit of using Node.js, lightweight and straightforward. But creating a website from scratch again and again is not acceptable. The good news is that, Node.js utilizes CommonJS as its module system, so that we can leverage some modules to simplify our job. And furthermore, there are about ten thousand of modules available n the internet, which covers almost all areas in server side application development.   NPM and Node.js Modules Node.js utilizes CommonJS as its module system. A module is a set of JavaScript files. In Node.js if we have an entry file named “index.js”, then all modules it needs will be located at the “node_modules” folder. And in the “index.js” we can import modules by specifying the module name. For example, in the code we’ve just created, we imported a module named “http”, which is a build-in module installed alone with Node.js. So that we can use the code in this “http” module. Besides the build-in modules there are many modules available at the NPM website. Thousands of developers are contributing and downloading modules at this website. Hence this is another benefit of using Node.js. There are many modules we can use, and the numbers of modules increased very fast, and also we can publish our modules to the community. When I wrote this post, there are totally 14,608 modules at NPN and about 10 thousand downloads per day. Install a module is very simple. Let’s back to our command windows and input the command “npm install express”. This command will install a module named “express”, which is a MVC framework on top of Node.js. And let’s create another JavaScript file named “helloweb.js” and copy the code below in it. I imported the “express” module. And then when the user browse the home page it will response a text. If the incoming URL matches “/Echo/:value” which the “value” is what the user specified, it will pass it back with the current date time in JSON format. And finally my website was listening at 12345 port. 1: var express = require("express"); 2: var app = express(); 3:  4: app.get("/", function(req, res) { 5: res.send("Hello Node.js and Express."); 6: }); 7:  8: app.get("/Echo/:value", function(req, res) { 9: var value = req.params.value; 10: res.json({ 11: "Value" : value, 12: "Time" : new Date() 13: }); 14: }); 15:  16: console.log("Web application opened."); 17: app.listen(12345); For more information and API about the “express”, please have a look here. Start our application from the command window by command “node helloweb.js”, and then navigate to the home page we can see the response in the browser. And if we go to, for example http://localhost:12345/Echo/Hello Shaun, we can see the JSON result. The “express” module is very populate in NPM. It makes the job simple when we need to build a MVC website. There are many modules very useful in NPM. - underscore: A utility module covers many common functionalities such as for each, map, reduce, select, etc.. - request: A very simple HTT request client. - async: Library for coordinate async operations. - wind: Library which enable us to control flow with plain JavaScript for asynchronous programming (and more) without additional pre-compiling steps.   Node.js and IIS I demonstrated how to run the Node.js application from console. Since we are in Windows another common requirement would be, “can I host Node.js in IIS?” The answer is “Yes”. Tomasz Janczuk created a project IISNode at his GitHub space we can find here. And Scott Hanselman had published a blog post introduced about it.   Summary In this post I provided a very brief introduction of Node.js, includes it official definition, architecture and how it implement the event-driven non-blocking model. And then I described how to install and run a Node.js application on windows console. I also described the Node.js module system and NPM command. At the end I referred some links about IISNode, an IIS extension that allows Node.js application runs on IIS. Node.js became a very popular server side application platform especially in this year. By leveraging its non-blocking IO model and async feature it’s very useful for us to build a highly scalable, asynchronously service. I think Node.js will be used widely in the cloud application development in the near future.   In the next post I will explain how to use SQL Server from Node.js.   Hope this helps, Shaun All documents and related graphics, codes are provided "AS IS" without warranty of any kind.
