• Microsoft Tag Tagged Me

  - by Brian Schroer

  I got EXTREMELY lucky last week and won an HP Mini 311 notebook from a Microsoft Tag Twitter contest. I did my required tweet to enter last Tuesday, and one hour later received notification that I had won the weekly drawing. Apparently you can tweet up to 500 times (I pity the followers of those who do that), so it was really lucky that I won, and I sympathize with those who had been really trying. If you would like to try your luck, there are seven weekly prizes left, and you can find out about the contest here: http://tag.microsoft.com/ttcontest.aspx For a free PC, I thought it was the least I could do to find out what Microsoft Tag is. I was vaguely aware of those pastel-y triangle-y square things that look like someone put one of Don Johnson’s Miami Vice outfits through a shredder, and knew that the company I work for (one of the world’s largest consumer products companies) was looking into putting them on our products, packaging and advertising, but didn’t know much more about the technology. I thought they were just an improvement over bar codes, and would be used in retail store scanners, but I was mistaken. These tags are meant to be scanned by consumers using their mobile phones, to get instant access to information, websites, reviews, etc. Scanning a tag can open a web page, import a contact card, or dial a phone number, play a video… Tag reader software can be installed on Windows Mobile, iPhone, Symbian, Blackberry, Android, J2ME, and other phones (and I suspect that it will be available for Windows Phone 7 also :). There are built-in tracking, metrics and analysis tools, to help companies using Tag make decisions about their marketing expenditures. (And they don’t have to look Miami Vice-y – They can be customized to reflect the personality of the person or a brand.) Looks like interesting stuff. You can find out more at http://tag.microsoft.com.

• How to prevent duplication of content on a page with too many filters?

  - by Vikas Gulati

  I have a webpage where a user can search for items based on around 6 filters. Currently I have the page implemented with one filter as the base filter (part of the url that would get indexed) and other filters in the form of hash urls (which won't get indexed). This way the duplication is less. Something like this example.com/filter1value-items#by-filter3-filter3value-filter2-filter2value Now as you may see, only one filter is within the reach of the search engine while the rest are hashed. This way I could have 6 pages. Now the problem is I expect users to use two filters as well at times while searching. As per my analysis using the Google Keyword Analyzer there are a fare bit of users that might use two filters in conjunction while searching. So how should I go about it? Having all the filters as part of the url would simply explode the number of pages and sticking to the current way wouldn't let me target those users. I was thinking of going with at max 2 base filters and rest as part of the hash url. But the only thing stopping me is that it would lead to duplication of content as per Google Webmaster Tool's suggestions on Url Structure.

• Real-time stock market application

  - by Sam

  I'm an amateur programmer. I'd like to develop a software application (like Tradestation), to analyse real-time market data. Please teach me if the following approach is correct, ie the procedures, knowledge or software needed etc: Use a DB to read the real-time feed from data provider: what should be the right DB to use? I know it should be a time serious one. Can I use SQL, Mysql, or others? What database can receive real-time data feed? Do I need to configure the DB to do this? If the real-time data is in ASCII form, how can it be converted to those that can be read by the DB and my application? Should I have to write codes or just use some add-ins? What kind of add-in are needed? How should I code the program to retrieve the changing data from the DB so that the analysis software screen data can also change asynchronously? (like the RTD in excel) Which aspects of programming do I need to learn to develop the above? Are there web resources/ books I can refer to for more information?

• Social Retailing

  - by David Dorf

  For retailers the move to mobile has been obvious.  More and more consumers are interacting with retailers, both online and in the store, using their mobile devices.  Retailers are quick to invest in both consumer facing mobile apps as well as ones to equip employees.  But when I talk to retailers about social, the value isn't as clear-cut.  Intuitively, retailers know that better relationships with customers will result in higher sales, but the trip to get there has many paths. The interesting thing about social media is that it has the potential to permeate all parts of the business.  Obviously it works well for marketing, but it also has a place with recruiting, knowledge management, trend analysis, and employee collaboration.  Information gathered from social media can enhance existing processes like assortment planning, product development, space planning, promotion planning, and replenishment.  Letting the customer influence each of these areas helps align the experience. One of the things holding retailers back is the lack of consistent and integrated tools to manage social media and make sense of the huge amounts of data.  To that end Oracle has been aggressively acquiring in the space, as depicted in the infographic below.  Soon, social will get the same level of investment as mobile.

• Secure Coding Practices in .NET

  - by SoftwareSecurity

  Thanks to everyone who helped pack the room at the Fox Valley Day of .NET.   This presentation was designed to help developers understand why secure coding is important, what areas to focus on and additional resources.  You can find the slides here. Remember to understand what you are really trying to protect within your application.  This needs to be a conversation between the application owner, developer and architect.  Understand what data (or Asset) needs to be protected.  This could be passwords, credit cards, Social Security Numbers.   This also may be business specific information like business confidential data etc.  Performing a Risk and Privacy Assessment & Threat Model on your applications even in a small way can help you organize this process. These are the areas to pay attention to when coding: Authentication & Authorization Logging & Auditing Event Handling Session and State Management Encryption Links requested Slides Books The Security Development Lifecycle: SDL: A Process for Developing Demonstrably More Secure Software Threat Modeling Writing Secure Code The Web Application Hackers Handbook  Secure Programming with Static Analysis   Other Resources: OWASP OWASP Top 10 OWASP WebScarab OWASP WebGoat Internet Storm Center Web Application Security Consortium Events: OWASP AppSec 2011 in Minneapolis

• How to handle coworker with "obsessive refactoring disorder"

  - by ThuneGrill

  My coworker (who is very clever, but with severly limited inter-personal skills), keeps refactoring my code even when it is work in progress and assigned to me as a task. Whereas I fully subscribed to the idea of collective ownership of code, I find this extremely irritating, but attempts to have him stop seem to have no effect. My analysis of his personality is that he considers himself the best, and if it had not been for him, the codebase would have been in a mess. I should add that I am not a novice, I know my skills and I produce quality work. Some of the refactorings are indeed to the better, most are basically just introduction of a style that he likes better than mine. In addition, he has a almost child-like need to have the last word in any discussion and has never any word of praise for work done by co-workers. There is always something that he, the master, would have done differently. I feel this is strongly affecting the quality of my work-life. What should I do ?

• System testing - making sure the system conforms to specification. Validation?

  - by user970696

  After weeks of research I have nearly completed my thesis, yet I am unable to clear up my confusion contained in all previous threads here (and in many books): During system testing, we check the system function against system analysis (functional system design) - but that would fit to a definition of verification according to many books. But I follow ISO12207, which considers all testing as validation (making sure work product meets requirement for intended use). How can I justify that unit testing or system testing is validation, even though when I check it against specification? Which fullfils the definiton of verification? When testing that e.g. "Save button" works, is it validation? This picture shows my understanding of V&V, so different from many other sources, including ISTQB etc. Essential problem I have is that a book using the same picture also states on another place that: test activities in the area of validation are usability, alpha and beta testing. For verification, testable system requirements are defined whose correct implementation can be tested through system tests. Isn't that the opposite of what the picture says? Most books present the following picture, where validation is just making sure that customer needs are satisfied. Mind you that according to ISO, validation activity is testing.

• Semantic Versioning and splitting apart a library, providing a bundled build

  - by Derick Bailey

  I've got a nice, fairly popular JavaScript library that is following Semantic Versioning. The current library has a few dependency libraries, which are available either as separate downloads or as part of a single bundled download. I see a need to head down this path further. I want to extract additional, smaller libraries out of the one larger library. Each of these extracted libraries would be available as separate files, or inside of the one bundled build, again. If I go down this path of extracting the libraries, and providing a bundled version of the final code, does this require a full version change in semantic versioning? Would I have to bump from 1.x to 2.x? My first thought it no: I will not change any public API, so I don't have to change the major version number. But then I wonder... well, I am restructuring a lot of things, even though the final API for the bundled version would be the same. Is there a clear answer from semver on something like this? Do I need to bump first, second or third dot? Or something else?

• Automatic Generalization

  - by Nick Harrison

  I have been interested in functional programming since college. I played around a little with LISP back then, but I have not had an opportunity since then. Now that F# ships standard with VS 2010, I figured now is my chance. So, I was reading up on it a little over the weekend when I came across a very interesting topic. F# includes a concept called "Automatic Generalization". As I understand it, the compiler will look at your method and analyze how you are using parameters. It will automatically switch to a generic parameter if it is possible based on your usage. Wow! I am looking forward to playing with this. I have long been an advocate of using the most generic types possible especially when developing library classes. Use the highest level base class that you can get away with. Use an interface instead of a specific implementation. I don't advocate passing object around, but you get the idea. Tools like resharper, fxCop, and most static code analysis tools provide guidance to help you identify when a more generalized type is possible, but this is the first time I have heard about the compiler taking matters into its own hands. I like the sound of this. We'll see if it is a good idea or not. What are your thoughts? Am I missing the mark on what Automatic Generalization does in F#? How would this work in C#? Do you see any problems with this?

• Rule of thumb for cost vs. savings for code re-use

  - by Styler

  Is it a good rule of thumb to always write code for the intent of re-using it somewhere down the road? Or, depending on the size of the component you are writing, is it better practice to design it for re-use when it makes sense with regards to time spent on it. What is a good rule of thumb for spending extra time on analysis and design on project components that have "some probability" of being needed later down the road for other things that may or may need this part. For example, if I have the need for project X to do things A, and B. A definitely needs to be written for re-use because it just makes sense to do so. B is very project specific at the moment, and I can hack it all together in a couple days to finish the project on time and give everyone kudos for being a great team, etc. Or if we say, lets spend a whole friggin' 2 weeks figuring out what project Y/Z might need this thing for and spend a load of extra time on on part B because someday we might need to use it on project Y/Z (where the savings will be realized). I'd imagine a perfect world situation would be a nicely crafted combination of project specific vs. re-use architected components given the project. However some code shops might feel it would be a great idea to write everything for the intention of using it at some point down the road.

• How to Set Up a MongoDB NoSQL Cluster Using Oracle Solaris Zones

  - by Orgad Kimchi

  This article starts with a brief overview of MongoDB and follows with an example of setting up a MongoDB three nodes cluster using Oracle Solaris Zones. The following are benefits of using Oracle Solaris for a MongoDB cluster: • You can add new MongoDB hosts to the cluster in minutes instead of hours using the zone cloning feature. Using Oracle Solaris Zones, you can easily scale out your MongoDB cluster. • In case there is a user error or software error, the Service Management Facility ensures the high availability of each cluster member and ensures that MongoDB replication failover will occur only as a last resort. • You can discover performance issues in minutes versus days by using DTrace, which provides increased operating system observability. DTrace provides a holistic performance overview of the operating system and allows deep performance analysis through cooperation with the built-in MongoDB tools. • ZFS built-in compression provides optimized disk I/O utilization for better I/O performance. In the example presented in this article, all the MongoDB cluster building blocks will be installed using the Oracle Solaris Zones, Service Management Facility, ZFS, and network virtualization technologies. Figure 1 shows the architecture:

• Discovering Your Project

  - by Tim Murphy

  The discovery phase of any project is both exciting and critical to the project’s success.  There are several key points that you need to keep in mind as you navigate this process. The first thing you need to understand is who the players in the project are and what their motivations are for the project.  Leaving out a key stakeholder in the resulting product is one of the easiest ways to doom your project to fail.  The better the quality of the input you have at this early phase the better chance you will have of creating a well accepted deliverable. The next task you should tackle is to gather the goals for the project.  Specifically, what does the company expect to get for the money they are about to layout.  This seems like a common sense task, but you would be surprised how many teams to straight to building the system.  Even if you are following an agile methodology I believe that this is critical. Inventorying the resources that already exists gives you an idea what you are going to have to build and what you can leverage at lower risk.  This list should include documentation, servers, code repositories, databases, languages, security systems and supporting teams.  All of these are “resources” that can effect the cost and delivery schedule of your project. Finally, you need to verify what you have found and documented with the stakeholders and subject matter experts.  Documentation that has not been reviewed is actually a list of assumptions and we all know that assumptions are the mother of all screw ups. If you give the discovery phase of your project the attention that it deserves your project has a much better chance of success. I would love to hear what other people find important for this phase.  Please leave comments on this post so we can share the knowledge. del.icio.us Tags: Project discovery,documentation,business analysis,architecture

• How do I copy a package from Debian to my PPA?

  - by Bernhard Reiter

  I'd like to add the latest gourmet package from Debian sid to our team's PPA so Ubuntu users who would like to run an up-to-date version of Gourmet can add that PPA to their software sources. (Dependency-wise, that shouldn't be much of an issue as pretty much all our current dependencies are already available in all currently supported Ubuntu versions.) I've downloaded the *.dsc file and debian and orig tarballs, and even figured out I could use this for the package's source.changes file. I also downloaded the Debian maintainer's public key so dput can validate the package. I then tried to upload the package to our PPA using dput ppa:~gourmet/ppa gourmet_0.17.3-1_source.changes (I also tried without the tilda.) This seemed to succeed, but I didn't get a confirmation email, and no packages are now displayed at our PPA, which leads me to believe that the package was rejected because the Debian maintainer's key is obviously not among our team members' keys. So what's the easiest way to "copy" a package from Debian (sid) to a Launchpad PPA? Do I really need to rebuild the entire package locally before I can upload it?

• How to analyze data

  - by Subhash Dike

  We are working on an application that allows user to search/read some content in a particular domain. We wanted to add some capability in the app which can suggest user some content based on the usage pattern (analyze data based on frequency and relevance). Currently every time user search or read something we do store that information in backend database. We would like to use this data to present some additional content to user. Could someone explain what kind of tools will be required for such a job and any example? And what this concept is called, data analysis? data mining? business intelligence? or something else? Update: Sorry for being too broad, here is an example SQL Database (Just to give an idea, actual db is little different with normalization and stuff) Table: UserArticles Fields: UserName | ArticleId | ArticleTitle | DateVisited | ArticleCategory Table: CategoryArticles Fields: Category | Article Title | Author etc. One Category may have one more articles. One user may have read the same article multiple times (in this case we place additional entry in the user article table. Task: Use the information availabel in UserArticle table and rank categories in order which would be presented to user automatically in other part of application. Factors to be considered are frequency and recency. This might be possible through simple queries or may require specialized tools. Either way, the task is what mention above. I am not too sure which route to take, hence the question. Thoughts??

• MvcReportViewer v.0.4.0 is available!

  - by Ilya Verbitskiy

  Originally posted on: http://geekswithblogs.net/ilich/archive/2014/06/04/mvcreportviewer-v.0.4.0-is-available.aspxToday I released new version of MvcReportViewer. This release contains mostly bug fixes reported by library users. I am glad to see that Open Source model works and people try to contribute to the project! Thank you everybody for your bug repots and help with the project. Version 0.4.0 Added support for ASP.NET MVC 5 Removed jQuery dependency. I have not tested it on IE8 or earlier versions. Any help with testing is welcome! Fixed problem with SSRS keep-alive cookies. Keep-alive cookies are issued every time a report is opened during a browser session. Many people don't restart their browsers and in my case, Chrome doesn't get rid of the cookie session data on close - had to manually delete them for the reports to start working again. I added KeepSessionAlive control settings to manage SSRS keep-alive behavior. It is set to false by default to fix Bad Request 400: Request Too Long issue. You can find usage example in Fluent.cshtml. Fixed the bug when ReportViewer Control parameters was not parsed when ShowParameterPrompts parameter had not been set. Changed public static MvcReportViewerIframe MvcReportViewer method to use IEnumerable<KeyValuePair<string, object>> reportParameters instead of simple object. The reason is users reported that they mostly use multiple report parameters’ values. Added support for SSRS hosted on Windows Azure. Users should set MvcReportViewer.IsAzureSSRS property to true in Web.config to use Windows Azure authentication. I do not have Windows Azure SSRS and build the code using http://msdn.microsoft.com/en-us/library/gg552871.aspx#Authentication article. It would be nice if somebody from community tested the change or provided me a test report on Windows Azure for testing purposes.
