• A quick hello to the Western Kentucky .NET User Group

  - by Muljadi Budiman

  A few days back, I got a chance to speak at the Western Kentucky .NET User Group meeting in Murray, Kentucky.  The opportunity came up because the original speaker, Jeff Blankenburg, had another obligation and was thus unable to come to this meeting.  I volunteered to deliver his presentation, which is an overview of MIX10 conference. It was a great experience for me; got to drive around and do a little bit of sight-seeing – can’t say I’ve ever been to Kentucky before, so first trip ever there.  I got to meet the user group’s current lead, Tom Turner and got to chat and discuss about all kinds of stuff with the other members.  Cheers to Matt Gawarecki and Brandon Sharp! The presentation itself mostly covers new features in Visual Studio 2010, which was recently released on April 12 – got to demonstrate Historical Debugging in IntelliTrace, Parallel Stacks, View Call Hierarchy and show some Extensions.  We also covered some of the new functionalities in Silverlight 4 (using webcams, drag & drop support among others) and I got to show off Scott Guthrie’s Windows Phone 7 Twitter app.  Altogether, it was quite a bit to cover in 70 minutes or so, but I think everyone enjoyed it. Jeff provided me with the presentation slides (which I modify a bit) and demo applications; so I’m putting it up here for those that may be interested in downloading them.  Please keep in mind that all the demos were made with VS2010 RC, so there may be slight tweaks to get it to work on the RTM version.

• Rant - Why is Windows Azure not available in Africa?

  - by Allan Rwakatungu

  Yesterday at the .NET user group meeting in Kampala Uganda  I gave a talk on cloud computing with Windows Azure  (details will be in my next blog post). The guys where excited. Without owning they own inftrastucture and at low cost they can build scalable , highly available applications. Not quite. Azure accounts are only available to people in particular countries - none from Africa. I attended PDC in 2008 when Microsoft unleashed Windows Azure. One of the case studies to show the benefits ofr cloud computing was a project in Africa for an education service in Ethiopia. The point they where making was that the cloud was perfect for scenarios where computing infrastructure is not sophiscated, like Ethiopia. Perfect , i thought. So i got my beta account from PDC and started playing around in the cloud. Then Azure goes live , my beta account does not work any more and I cant pay because am from Uganda. Microsoft , this sucks. I dont know the reasons for Microsoft doing this, but am sure we can work out something. We in Africa need the cloud more than anybody else in the world. Setting up data centers that are higly scalable and available for our startups is not an option we have. But we also cant pay for cloud computing with Microsoft. Microsoft, we know we are a tiny insigficant market for a company your size, but your excluding us only continues to widen the digital divide. Microsoft , how about you have a reseller model for cloud computing. Instead of trying to deal direclty with each client you have local partners who help you sell and bill your cloud services. I think that would lead to Windows Azure being available in Africa. I can help you resell in Uganda.

• Working with a company as a Junior Developer [closed]

  - by user1601973

  We all have started our careers in some way or other. Well, I am a college student based in North America & I am doing my second internship with the same company with which I did my first internship. I came back here because people here were helpful always and supportive. But it just happened today, and I wanted to share this on SO. Well since I started I have been doing documentation and that kind of stuff only as compared to my first internship in which I actually worked along with the developers & learned so many things. Well, I was in a conversation with my Team lead, and he asked me if I completed that particular work or not? Well, That particular work had slipped from my mind. He was indeed I kind of pissed, and said "You don't have to worry about it, I will figure out". Well, I felt so bad and was about to literally cry. I stopped my lunch and then went on to complete that work. I always ask for work in office, and I always try to be an asset for whoever I am working but this was the first time that it happened. What are your thoughts on this and should I apologise or not? I think I should.

• Is it OK to reoccupy my old GitHub username to protect repository redirections?

  - by Idan Arye

  I'm considering changing my GitHub username from the old alias I was using as a kid to my real name. I'm concerned about my repository URLs. GitHub will redirect the old URLs, but if someone creates a new account using my old username and creates a repository with the same name as one of my repositories, the URL redirection will break and the URL will lead to their repository, not mine. Now, this is understandable, and GitHub recommends to not count on the redirect in the long term, and update all the remotes, but I'm concerned about some Vim plugins I'm hosting on GitHub. It's a common practice to manage Vim plugins with Git(either as separate repositories or as submodules), and if one of the plugins' remotes break you'll get error messages when you try to batch-update all your plugins(it happened to me once...). It's not that hard to solve, and the chances that'll happen are slim, but I would still like to avoid causing trouble to the users of my plugins... To prevent this, I think to create a new account with my old username. That way I can avoid the risk of someone else taking my old username and breaking the redirects of my old repositories. While researching this approach I've found GitHub's Name Squatting Policy. According to that policy, GitHub can delete or rename inactive accounts. To my understanding, they do this to prevent Cybersquatting, but surely this isn't the case with my fake account - I'm not holding someone else's name in an attempt to sell it to them, I'm merely occupying a name I was using to protect my old URLs... So, is it acceptable to go with this plan an create a fake account with my old username?

• 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.

• There is No Scrum without Agile

  - by John K. Hines

  It's been interesting for me to dive a little deeper into Scrum after realizing how fragile its adoption can be.  I've been particularly impressed with James Shore's essay "Kaizen and Kaikaku" and the Net Objectives post "There are Better Alternatives to Scrum" by Alan Shalloway.  The bottom line: You can't execute Scrum well without being Agile. Personally, I'm the rare developer who has an interest in project management.  I think the methodology to deliver software is interesting, and that there are many roles whose job exists to make software development easier.  As a project lead I've seen Scrum deliver for disciplined, highly motivated teams with solid engineering practices.  It definitely made my job an order of magnitude easier.  As a developer I've experienced huge rewards from having a well-defined pipeline of tasks that were consistently delivered with high quality in short iterations.  In both of these cases Scrum was an addition to a fundamentally solid process and a huge benefit to the team. The question I'm now facing is how Scrum fits into organizations withot solid engineering practices.  The trend that concerns me is one of Scrum being mandated as the single development process across teams where it may not apply.  And we have to realize that Scurm itself isn't even a development process.  This is what worries me the most - the assumption that Scrum on its own increases developer efficiency when it is essentially an exercise in project management. Jim's essay quotes Tobias Mayer writing, "Scrum is a framework for surfacing organizational dysfunction."  I'm unsure whether a Vice President of Software Development wants to hear that, reality nonwithstanding.  Our Scrum adoption has surfaced a great deal of dysfunction, but I feel the original assumption was that we would experience increased efficiency.  It's starting to feel like a blended approach - Agile/XP techniques for developers, Scrum for project managers - may be a better fit.  Or at least, a better way of framing the conversation. The blended approach. Technorati tags: Agile Scrum

• Antenna Aligner part 2: Finding the right direction

  - by Chris George

  Last time I managed to get "my first app(tm)" built, published and running on my iPhone. This was really cool, a piece of my code running on my very own device. Ok, so I'm easily pleased! The next challenge was actually trying to determine what it was I wanted this app to do, and how to do it. Reverting back to good old paper and pen, I started sketching out designs for the app. I knew I wanted it to get a list of transmitters, then clicking on a transmitter would display a compass type view, with an arrow pointing the right way. I figured there would not be much point in continuing until I know I could do the graphical part of the project, i.e. the rotating compass, so armed with that reasoning (plus the fact I just wanted to get on and code!), I once again dived into visual studio. Using my friend (google) I found some example code for getting the compass data from the phone using the PhoneGap framework. // onSuccess: Get the current heading // function onSuccess(heading) {    alert('Heading: ' + heading); } navigator.compass.getCurrentHeading(onSuccess, onError); Using the ripple mobile emulator this showed that it was successfully getting the compass heading. But it didn't work when uploaded to my phone. It turns out that the examples I had been looking at were for PhoneGap 1.0, and Nomad uses PhoneGap 1.4.1. In 1.4.1, getCurrentHeading provides a compass object to onSuccess, not just a numeric value, so the code now looks like // onSuccess: Get the current magnetic heading // function onSuccess(heading) {    alert('Heading: ' + heading.magneticHeading); }; navigator.compass.getCurrentHeading(onSuccess, onError); So the lesson learnt from this... read the documentation for the version you are actually using! This does, however, lead to compatibility problems with ripple as it only supports 1.0 which is a real pain. I hope that the ripple system is updated sometime soon.

• Developing configuration syntax - best practise/rules/methods?

  - by Isaac

  I am currently developing a small application, which checks if provided data meets certain requirements. The requirements are actually a long list, and might be changing, so I defined a syntax which allows me to state all of the requirements briefly and in a seperate file. Now the overall requirements for the application have changed, and I need to change my configuration syntax. Which leeds me to wonder if there is methodoloy or best practise for developing such syntaxes. Currently what I do is I think about the requirements and come up with an initial syntax, start configuring the first few items and see how it works. If I come upon something that does not work well or not at all with the current syntax, I change the syntax, if possible in a backward compatible way. This somehow works for me, but it feels a bit like fishing in troubled water. Also I feel it does not nessessarly lead to the most concise and easy to understand/use syntax. So I was wondering what other people do, especially if there is a better approach to this.

• How do I make money from my FOSS while staying anonymous?

  - by user21007

  Let's say that: You have created a FOSS project that other people find useful, perhaps useful enough to donate to or pay for modifications to be done. It is a perfectly legitimate and innocuous software project. It has nothing to do with cryptography as munitions, p2p music, or anything likely to lead to a search warrant or being sued. You want your involvement to stay anonymous or pseudonymous. You would like to receive some money for your efforts, if people are willing. Is that possible, and if so, how could it be done? When I talk about anonymity, I realize that it is necessary to define the extent. I am not talking about Wikileaks style 20 layers of proxies worth of anonymity. I would expect a 3 letter agency to be able to identify the person easily. What is wanted is shielding from commercial competitors or random people, who would not be expected to be able to get the financial intermediary to divulge your details just by asking for them. Why would you want to stay anonymous? I can think of several valid reasons, maybe you operate a stealth mode startup and don't want to give your competitors clues as to the technology you are using. Maybe it is a project that has nothing to do with your daily job, is not developed there, but the company you work for has an unfair (and possibly unenforceable) policy stating that any coding you do is owned by them. Maybe you just value your privacy. For what it's worth, you intend to pay the relevant taxes in your country on any donations.

• Is my concept in open source license correct?

  - by tester

  I would like to justify whether my concept in the open source license is correct, as you know that, misunderstanding the terms may lead to a serious law sue. Thank you. The main difference among the open source license is whether the license is copyleft. Copyleft license means allow the others to reproduce, modify and distribute the products but the released product is bound by the same licensing restriction. That means they have to use the same license for the modified version. Also, the copyleft license require all the released modified version to be free software. On the other hand, if any others create derived work incorporating non-copyleft licensed code, they can choose any license for the code. The serveral kinds of license and comparsion GPL is a restrictive license. Software requires to released as GPL license if that integrate or is modified from the other GPL license software . The library used in developing GPL license software are also restricted to GPL and LGPL , proprietary software are not allowed to employ (or complied with) in any part of the GPL application. LGPL is similar to GPL , but was more permissive with regarding allow the using of other non-GPL software. BSD is relatively simple license, it allow developer to do anything on the original source code . The license holder do not hold any legal responsibilities for their released product. Apache license is evolved from the BSD license. The legal terms are improved and are written by legal professionals in a more modern way. It covers comprehensive intellectual property ownership and liability issues. Also, are there any popular license beside these? Thank you

• Are web application usability issues equal to website usability issues?

  - by Kor

  I've been reading two books about web usability issues and tests (Rocket Surgery Made Easy¹ and Prioritizing Web Usability²) and they claim some strategies and typical problems about website usability and how to lead them. However, I want to do a web application, and I think I lost track of what I am trying to solve. These two books claim to work with raw websites (e-commerce, business sites, even intranet), but I'm not sure if everything about web usability is applicable to web application usability. They sure talk about always having available (and usable) the Back button, to focus on short information rather than big amounts of text, etc., but they could be inaccurate in deeper problems that may be easier (or just skippable) in regular websites. Has anybody some experience in this field and could tell me if both web applications and websites share their usability issues? Thanks in advance Edit: Quoting Wikipedia, a website is a collection of related web pages containing images, videos or other digital assets, and a web application is an application that is accessed over a network such as the Internet or an intranet. To sum up, both shows/lets you search/produce information but websites are "simple" in interaction and keep the classics of websites (one-click actions) and the other one is closer to desktop applications in the meaning of their uses and ways of interaction (double click, modal windows, asynchronous calls [to keep you in the same "environment" instead of reloading it] etc.). I don't know if this clarifies the difference. Edit 2: Quoting @Victor and myself, a website is anything running in your browser, but a web application is somewhat running in your browser that could be running in your desktop, with similar behaviors and features. Gmail is a web application that could replace Outlook. GDocs could replace Office. Grooveshark could replace your music player, etc.

• How can rotating release managers improve a project's velocity and stability?

  - by Yannis Rizos

  The Wikipedia article on Parrot VM includes this unreferenced claim: Core committers take turns producing releases in a revolving schedule, where no single committer is responsible for multiple releases in a row. This practice has improved the project's velocity and stability. Parrot's Release Manager role documentation doesn't offer any further insight into the process, and I couldn't find any reference for the claim. My first thoughts were that rotating release managers seems like a good idea, sharing the responsibility between as many people as possible, and having a certain degree of polyphony in releases. Is it, though? Rotating release managers has been proposed for Launchpad, and there were some interesting counterarguments: Release management is something that requires a good understanding of all parts of the code and the authority to make calls under pressure if issues come up during the release itself The less change we can have to the release process the better from an operational perspective Don't really want an engineer to have to learn all this stuff on the job as well as have other things to take care of (regular development responsibilities) Any change of timezones of the releases would need to be approved with the SAs and: I think this would be a great idea (mainly because of my lust for power), but I also think that there should be some way making sure that a release manager doesn't get overwhelmed if something disastrous happens during release week, maybe by have a deputy release manager at the same time (maybe just falling back to Francis or Kiko would be sufficient). The practice doesn't appear to be very common, and the counterarguments seem reasonalbe and convincing. I'm quite confused on how it would improve a project's velocity and stability, is there something I'm missing, or is this just a bad edit on the Wikipedia article? Worth noting that the top voted answer in the related "Is rotating the lead developer a good or bad idea?" question boldly notes: Don't rotate.

• A (slight) Change of Focus

  - by StuartBrierley

  When I started this blog in September 2009 I was working as a BizTalk developer for a financial institution based in the South West of England.  At the time I was developing using BizTalk Server 2004 and intended to use my blog to collate and share any useful information and experiences that I had using this version of BizTalk (and occasionally other technologies) in an effort to bring together as many useful details as I could in one place. Since then my circumstances have changed and I am no longer working in the financial industry using BizTalk 2004.  Instead I have recently started a new post in the logistics industry, in the North of England, as "IT Integration Manager".  The company I now work for has identified a need to boost their middleware/integration platform and have chosen BizTalk Server 2009 as their platform of choice; this is where I come in. To start with my role is to provide the expertise with BizTalk that they currently lack, design and direct the initial BizTalk 2009 implementation and act as lead developer on all pending BizTalk projects.  Following this it is my hope that we will be able to build on the initial BizTalk "proof of concept" and eventually implement a fully robust enterprise level BizTalk 2009 environment. As such, this blog is going to see a shift in focus from BizTalk 2004 to BizTalk 2009 and at least initially is likely to include posts on the design and installation of our BizTalk environment - assuming of course that I have the time to write them! The last post I made was the start of a chapter by chapter look at the book SOA Patterns with BizTalk Server 2009.  Due to my change of job I am currently "paused" half way through this book, and my lack of posts on the subject are directly as a result of the job move and the pending relocation of my family.  I am hoping to write about my overall opinion of this book sometime soon; so far it certainly looks like it will be a positive one. Thanks for reading; I'm off to manage some integration.

• How to organize a larger project with several sub-projects and their dependencies?

  - by RoToRa

  As a software developer until now, I've mostly worked on projects that were quite "monolithic" with hardly any dependencies on other projects, without building automation (no Make, Ant, Maven, etc.) and kept on a simple version control system (mostly Subversion) with just a few easily managed version branches. Now together with some friends I'm planning a project that is intended to run on multiple platforms (mostly mobile: Android, iOS, Kindle, Windows, etc.), thus written in several languages and on different development platforms. This will lead to many dependencies: All projects sharing the same resources (e.g. images) or projects dependent on each other (e.g. a core Java library project used by the Android and other Java based implementations). So what I need is some basic information on how to answer questions such as: How would the VCS be structured? Would a client-base or a decentralized VCS be better? How to decide building automation system(s) to use? Since this quite an open question I guess for now it would be great if you could point me to any books or web resources that you can recommend for this topic.

• Use MvcContrib Grid to Display a Grid of Data in ASP.NET MVC

  The past six articles in this series have looked at how to display a grid of data in an ASP.NET MVC application and how to implement features like sorting, paging, and filtering. In each of these past six tutorials we were responsible for generating the rendered markup for the grid. Our Views included the <table> tags, the <th> elements for the header row, and a foreach loop that emitted a series of <td> elements for each row to display in the grid. While this approach certainly works, it does lead to a bit of repetition and inflates the size of our Views. The ASP.NET MVC framework includes an HtmlHelper class that adds support for rendering HTML elements in a View. An instance of this class is available through the Html object, and is often used in a View to create action links (Html.ActionLink), textboxes (Html.TextBoxFor), and other HTML content. Such content could certainly be created by writing the markup by hand in the View; however, the HtmlHelper makes things easier by offering methods that emit common markup patterns. You can even create your own custom HTML Helpers by adding extension methods to the HtmlHelper class. MvcContrib is a popular, open source project that adds various functionality to the ASP.NET MVC framework. This includes a very versatile Grid HTML Helper that provides a strongly-typed way to construct a grid in your Views. Using MvcContrib's Grid HTML Helper you can ditch the <table>, <tr>, and <td> markup, and instead use syntax like Html.Grid(...). This article looks at using the MvcContrib Grid to display a grid of data in an ASP.NET MVC application. A future installment will show how to configure the MvcContrib Grid to support both sorting and paging. Read on to learn more! Read More >

• Rope Colliding with a Rectangle

  - by Colton

  I have my rope, and I have my rectangles. The rope is similar to the implementation found here: http://nehe.gamedev.net/tutorial/rope_physics/17006/ Now, I want to make the rope properly collide with the rectangle such that the rope will not pass through a rectangle, and wrap around the rectangle and all that good stuff. Currently, I have it set so no rope node can pass through a rect (successfully), however, this means a rope segment can still pass through a block. Ex: So the question is, what can I do to fix this? What I have tried: I create a rectangle between two nodes of a rope, calculate rotation between the nodes, and get myself a transformed rectangle. I can successfully detect a collision between rope segments and a (non-transformed) rectangle. Create a new node or pivot point around the corner of the block, and rearrange nodes to point to the corner node. Trouble is determining what corner the rope segment is passing through. And then the current rope setup goes wonky (based on verlet integration, so a sudden change in position causes the rope to wiggle like a seismograph during a magnitude 8 earth quake.) Among other issues that might be solvable, but its turning into a case by case thing, which doesn't seem right. I think the best answer here would just be a link to a tutorial (I simply can't find any, most lead to box2D or farseer, but I want to at least learn how it works before I hide behind an engine).

• Web migration of a VB6 system with VWG

  - by Webgui

  Brinks Bolivia eSAC System (Customer Service) allows to register all different kinds of contacts for a customer; addition to maintaining an updated status of each service or customer request, to have accurate information and perform the appropriate procedures for all applications. The system was originally developed in VB6 and since web access was essential it was offered via Citrix. Since the application's performance was a critical issue as well as the need to offer the system without specific installations the company looked for a solution that would solve those drawbacks of using Citrix. Searching for a solution that would allow it to offer the eSAC system over the web without the need for specific client installations and provide sufficient performance levels even when there is limited bandwidth lead Brinks to a decision to migrate their VB6 Customer Service system to to Visual WebGui. "Developing on Visual WebGui we were able to migrate the system to web environment and even add new features in less time which allows us to offer it over a standard web browser with better performance and no installations as was required with Citrix," concluded Alexander Cuellar. The full article and screenshots of the system are available here.

• How do you KISS?

  - by Conor

  The KISS principle is a highly quoted design mantra. The aim of this principle is to stamp out unnecessary complexity on a project. This is a good thing, saving time, energy and money. It can lead to a relatively stress free implementation and a simple, elegant, maintainable end product. A lot of discussion on KISS provides mechanisms to simplify requirements, design and implementation. Things that spring to mind include: avoid scope creep; simple obvious design and code; minimal run-time dependencies; refactoring to maintain simplicity; etc. However there are a lot of implicit things that we do to KISS. Examples: small team sizes; minimal management layers; tidy desk; mastery of a single IDE; clear concise error messages; scripts to automate/encapsulate tasks; etc Why KISS practices do you apply? How have they been of benefit? I'm especially interested in non-obvious practices.

• RPi and Java Embedded GPIO: Hooking Up Your Wires for Java

  - by hinkmond

  So, you bought your blue jumper wires, your LEDs, your resistors, your breadboard, and your fill of Fry's for the day. How do you hook this cool stuff up to write Java code to blink them LEDs? I'll step you through it. First look at that pinout diagram of the GPIO header that's on your RPi. Find the pins in the corner of your RPi board and make sure to orient it the right way. The upper left corner pin should have the characters "P1" next to it on the board. That pin next to "P1" is your Pin #1 (in the diagram). Then, you can start counting left, right, next row, left, right, next row, left, right, and so on: Pins # 1, 2, next row, 3, 4, next row, 5, 6, and so on. Take one blue jumper wire and connect to Pin # 3 (GPIO0). Connect the other end to a resistor and then the other end of the resistor into the breadboard. Each row of grouped-together holes on a breadboard are connected, so plug in the short-end of a common cathode LED (long-end of a common anode LED) into a hole that is in the same grouping as where the resistor is plugged in. Then, connect the other end of the LED back to Pin # 6 (GND) on the RPi GPIO header. Now you have your first LED connected ready for you to write some Java code to turn it on and off. (As, extra credit you can connect 7 other LEDs the same way to with one lead to Pins # 5, 7, 11, 13, 15, 19 & 21). Whew! That wasn't so bad, was it? Next blog post on this thread will have some Java source code for you to try... Hinkmond
