  • The Social Business Thought Leaders - Ray Wang

    - by kellsey.ruppel
    It seems both consumers and businesses are at the peak of the social hype. Overwhelmed by social media channels, platforms, and processes both in their private and professional life, many early adopters are starting to feel the social fatigue. Mirroring what happened with email and web sites during the late 1990's - early 2000's, more and more managers are looking to move from ubiquitous social media tactics to the most appropriate business use case and processes. This step becomes even more important considering the year over year contraction in IT budgets and the consequent need to maximize return on every dollar spent in new technologies. Ray Wang, CEO and Principal Analyst at Constellation Research, suggests engagement through collaborative technologies both as a conceptual model and a transformational tool for enterprises to reap business value. Without participation - the reasoning goes - there is no value and good technology alone is not enough to guarantee employee and customer adoption. Enterprise gamification is a new lever to succeed with Social Business by directing a critical mass of participation towards desired outcomes. What kind of outcomes? A recent study from Constellation Research (see 2012 Q1 Gamification Early Adopters Best Practices) highlights how Marketing, Customer Service and HR are leading the pack with gamification in processes such as: Sustaining long term customer loyalty (76.4%) Improving response in campaign to lead (74.5%) Right channeling incidents for resolution in social media (67.3%) Growing the number service and support incidents resolved by the community (63.6%) Improving employee referral rates and effective recruiting (43.6%) Driving on-boarding success with new hires (20%) More than simply adding badges, points and leaderboards to existing processes, enterprise gamification should be holistically embedded into employee and customer experience to stimulate specific behaviors. According to Ray Wang this can be done at three core levels: Measurable actions. The behaviors we want to facilitate consist of granular actions (i.e likes, comments, posts, recommendations, etc) and more complex actions (i.e projects, initiatives, programmes) attributed to individuals, groups and/or external actors  Reputation. The reputation an individual has earned through his actions is a key factor in building motivation among others and it is determined by its identity, social standing status and competitiveness Incentives or the intrinsic and extrinsic rewards that motivate behaviors and drive actions Listen to Ray Wang's video-interview to learn more about the dynamics that are shaping the future of collaboration and how gamification can help organizations attain new levels of engagement.

  • How (recipe) to build only one kernel module?

    - by Pro Backup
    I have a bug in a Linux kernel module that causes the stock Ubuntu 14.04 kernel to oops (crash). That is why I want to edit/patch the source of only that single kernel module to add some extra debug output. The kernel module in question is mvsas and not necessary to boot. For that reason I don't see any need to update any initrd images. I have read a lot of information (as shown below) and find the setup and build process confusion. I need two recipes: to setup/configure the build environment once steps to do after editing any source file of this kernel module (.c and .h) and converting that edit into a new kernel module (.ko) The sources that have been used are: build one kernel module - Google search http://www.linuxquestions.org/questions/linux-kernel-70/rebuilding-a-single-kernel-module-595116/ http://stackoverflow.com/questions/8744087/how-to-recompile-just-a-single-kernel-module http://www.pixelbeat.org/docs/rebuild_kernel_module.html How do I build a single in-tree kernel module? http://ubuntuforums.org/showthread.php?t=1153067 http://ubuntuforums.org/showthread.php?t=2112166 http://ubuntuforums.org/showthread.php?t=1115593 build one kernel module ubuntu - Google search 'make +single +kernel +module' - Ask Ubuntu 'make +kernel +module' - Ask Ubuntu My makefile results in: No rule to make target `arch/x86/tools/relocs.c', needed '"Invalid module format"' - Ask Ubuntu Driver installation: compiling source code for newer kernel Modprobe: 'Invalid nodule format', yet works after insmod "Symbol version dump" "is missing" - Google search http://stackoverflow.com/questions/9425523/should-i-care-that-the-symbol-version-dump-is-missing-how-do-i-get-one Where can I find the corresponding Module.symvers and .config files for 12.04.3 i386 server?

  • Visual Studio 2010 plus Help Index : have your cake and eat it too

    - by Adrian Hara
    Although the team's intentions might have been good, the new help system in Visual Studio 2010  is a huge step backwards (more like a cannonball-shot-kind-of-leap really) from the one we all know (and love?) in Visual Studio 2008 and 2005 (and heck, even VS6). Its biggest problem, from my point of view, is the total and complete lack of the Help Index feature: you know...the thing where you just go and type in what you're looking for and it filters down the list of results automatically. For me this was the number one productivity feature in the "old" help system, allowing me to find stuff very quickly. Number two is that it's entirely web based and runs, by default, in the browser. So imagine, when you press F1, a new tab opens in your default browser pointing to the help entry. While this is wrong in many ways, it's also extremely annoying, cleaning up tabs in the browser becomes a chore which represents a serious productivity hit. These and many other problems were discussed extensively (and rather vocally) on connect but it seems MS seemed to ignore it and opt to release the new help system anyway, with the promise that more features will be added in a later release. Again, it kind of amazes me that they chose to ship a product with LESS features that the previous one and, what's worse, missing KEY features, just so it's "standards based" and "extensible". To be honest, I couldn't care less about the help system's implementation, I just want it to be usable and I would've thought that by now the software community and especially MS would've learned this lesson. In the end, what kind of saddens me is that MS regards these basic features as ones for the "power help user". I mean, come on! I mean a) it's not like my aunt's using Visual Studio 2010 and she represents the regular user, b) all software developers are, by definition, power users and c) it's a freakin help, not rocket science! As you can tell, I'm pretty pissed. Even more so because I really feel that the VS2010 & co. release really is a great one, with a lot of effort going into the various platforms and frameworks, most (if not all) of them being really REALLY good products. And then they go and screw up the help! How lame is that?!   Anyway, it's not all gloom-and-doom. Luckily there is a desktop app which presents a UI over the new help system that's very close to what was there in VS2008, by Robert Chandler (to which I hereby declare eternal gratitude). It still has some minor issues but I'll take it over the browser version of the help any day. It's free, pretty quick (on my machine ;)) and nicely usable. So, if you hate the new help system (passionately) like I do, download H3Viewer now.

  • Attach to Process in Visual Studio

    - by Daniel Moth
    One option for achieving step 1 in the Live Debugging process is attaching to an already running instance of the process that hosts your code, and this is a good place for me to talk about debug engines. You can attach to a process by selecting the "Debug" menu and then the "Attach To Process…" menu in Visual Studio 11 (Ctrl+Alt+P with my keyboard bindings), and you should see something like this screenshot: I am not going to explain this UI, besides being fairly intuitive, there is good documentation on MSDN for the Attach dialog. I do want to focus on the row of controls that starts with the "Attach to:" label and ends with the "Select..." button. Between them is the readonly textbox that indicates the debug engine that will be used for the selected process if you click the "Attach" button. If you haven't encountered that term before, read on MSDN about debug engines. Notice that the "Type" column shows the Code Type(s) that can be detected for the process. Typically each debug engine knows how to debug a specific code type (the two terms tend to be used interchangeably). If you click on a different process in the list with a different code type, the debug engine used will be different. However note that this is the automatic behavior. If you believe you know best, or more typically you want to choose the debug engine for a process using more than one code type, you can do so by clicking the "Select..." button, which should yield a "Select Code Type" dialog like this one: In this dialog you can switch to the debug engine you want to use by checking the box in front of your desired one, then hit "OK", then hit "Attach" to use it. Notice that the dialog suggests that you can select more than one. Not all combinations work (you'll get an error if you select two incompatible debug engines), but some do. Also notice in the list of debug engines one of the new players in Visual Studio 11, the GPU debug engine - I will be covering that on the C++ AMP team blog (and no, it cannot be combined with any others in this release). Comments about this post by Daniel Moth welcome at the original blog.

  • Is inline SQL still classed as bad practice now that we have Micro ORMs?

    - by Grofit
    This is a bit of an open ended question but I wanted some opinions, as I grew up in a world where inline SQL scripts were the norm, then we were all made very aware of SQL injection based issues, and how fragile the sql was when doing string manipulations all over the place. Then came the dawn of the ORM where you were explaining the query to the ORM and letting it generate its own SQL, which in a lot of cases was not optimal but was safe and easy. Another good thing about ORMs or database abstraction layers were that the SQL was generated with its database engine in mind, so I could use Hibernate/Nhibernate with MSSQL, MYSQL and my code never changed it was just a configuration detail. Now fast forward to current day, where Micro ORMs seem to be winning over more developers I was wondering why we have seemingly taken a U-Turn on the whole in-line sql subject. I must admit I do like the idea of no ORM config files and being able to write my query in a more optimal manner but it feels like I am opening myself back up to the old vulnerabilities such as SQL injection and I am also tying myself to one database engine so if I want my software to support multiple database engines I would need to do some more string hackery which seems to then start to make code unreadable and more fragile. (Just before someone mentions it I know you can use parameter based arguments with most micro orms which offers protection in most cases from sql injection) So what are peoples opinions on this sort of thing? I am using Dapper as my Micro ORM in this instance and NHibernate as my regular ORM in this scenario, however most in each field are quite similar. What I term as inline sql is SQL strings within source code. There used to be design debates over SQL strings in source code detracting from the fundamental intent of the logic, which is why statically typed linq style queries became so popular its still just 1 language, but with lets say C# and Sql in one page you have 2 languages intermingled in your raw source code now. Just to clarify, the SQL injection is just one of the known issues with using sql strings, I already mention you can stop this from happening with parameter based queries, however I highlight other issues with having SQL queries ingrained in your source code, such as the lack of DB Vendor abstraction as well as losing any level of compile time error capturing on string based queries, these are all issues which we managed to side step with the dawn of ORMs with their higher level querying functionality, such as HQL or LINQ etc (not all of the issues but most of them). So I am less focused on the individual highlighted issues and more the bigger picture of is it now becoming more acceptable to have SQL strings directly in your source code again, as most Micro ORMs use this mechanism. Here is a similar question which has a few different view points, although is more about the inline sql without the micro orm context: http://stackoverflow.com/questions/5303746/is-inline-sql-hard-coding

  • Overload Avoidance

    - by mikef
    A little under a year ago, Matt Simmons wrote a rather reflective article about his terrifying brush with stress-induced ill health. SysAdmins and DBAs have always been prime victims of work-related stress, but I wonder if that predilection is perhaps getting worse, despite the best efforts of Matt and his trusty side-kick, HR. The constant pressure from share-holders and CFOs to 'streamline' the workforce is partially to blame, but the more recent culprit is technology itself. I can't deny that the rise of technologies like virtualization, PowerCLI, PowerShell, and a host of others has been a tremendous boon. As a result, individual IT professionals are now able to handle more and more tasks and manage increasingly large and complex environments. But, without a doubt, this is a two-edged sword; The reward for competence is invariably more work. Unfortunately, SysAdmins play such a pivotal role in modern business that it's easy to see how they can very quickly become swamped in conflicting demands coming from different directions. However, that doesn't justify the ridiculous hours many are asked (or volunteer) to devote to their work. Admirably though their commitment is, it isn't healthy for them, it sets a dangerous expectation, and eventually something will snap. There are times when everyone needs to step up to the plate outside of 'normal' work hours, but that time isn't all the time. Naturally, with all that lovely technology, you can automate more and more of those tricky tasks to keep on top of the workload, but you are still only human. Clever though you may be, there is a very real limit to how far technology can take you. I'm not suggesting that you avoid these technologies, or deliberately aim for mediocrity; I'm just saying that you need to be more than just technically skilled (and Wesley Nonapeptide riffs on and around this topic in his excellent 'Telepathic Robot Drones' blog post). You need to be able to manage expectations, not just Exchange. Specifically, that means your own expectations of what you are capable of, because those come before everyone else's. After all, how can you keep your work-life balance under control, if you're the one setting the bar way too high? Talking to your manager, or discussing issues with your users, is only going to be productive if you have some facts to work with. "Know Thyself" is the first law of managing work overload, and this is obviously a skill which people develop over time; the fact that veteran Sysadmins exist at all is testament to this. I'd just love to know how you get to that point. Personally, I'm using RescueTime to keep myself honest, but I'm open to recommendations for better methods. Do you track your own time, do you have an intuitive sense of what is possible, or do you just rely on someone else to handle that all for you? Cheers, Michael

  • How to refactor a Python “god class”?

    - by Zearin
    Problem I’m working on a Python project whose main class is a bit “God Object”. There are so friggin’ many attributes and methods! I want to refactor the class. So Far… For the first step, I want to do something relatively simple; but when I tried the most straightforward approach, it broke some tests and existing examples. Basically, the class has a loooong list of attributes—but I can clearly look over them and think, “These 5 attributes are related…These 8 are also related…and then there’s the rest.” getattr I basically just wanted to group the related attributes into a dict-like helper class. I had a feeling __getattr__ would be ideal for the job. So I moved the attributes to a separate class, and, sure enough, __getattr__ worked its magic perfectly well… At first. But then I tried running one of the examples. The example subclass tries to set one of these attributes directly (at the class level). But since the attribute was no longer “physically located” in the parent class, I got an error saying that the attribute did not exist. @property I then read up about the @property decorator. But then I also read that it creates problems for subclasses that want to do self.x = blah when x is a property of the parent class. Desired Have all client code continue to work using self.whatever, even if the parent’s whatever property is not “physically located” in the class (or instance) itself. Group related attributes into dict-like containers. Reduce the extreme noisiness of the code in the main class. For example, I don’t simply want to change this: larry = 2 curly = 'abcd' moe = self.doh() Into this: larry = something_else('larry') curly = something_else('curly') moe = yet_another_thing.moe() …because that’s still noisy. Although that successfully makes a simply attribute into something that can manage the data, the original had 3 variables and the tweaked version still has 3 variables. However, I would be fine with something like this: stooges = Stooges() And if a lookup for self.larry fails, something would check stooges and see if larry is there. (But it must also work if a subclass tries to do larry = 'blah' at the class level.) Summary Want to replace related groups of attributes in a parent class with a single attribute that stores all the data elsewhere Want to work with existing client code that uses (e.g.) larry = 'blah' at the class level Want to continue to allow subclasses to extend, override, and modify these refactored attributes without knowing anything has changed Is this possible? Or am I barking up the wrong tree?

  • More Changes...

    - by MOSSLover
    Stuff has changed drastically for me in the past two to three years.  I moved over 1000 miles from Saint Louis.  I go outside and I get up in front of crowds with less issues.  Now I'm changing jobs again.  I'm not really sure what to say here.  I was obviously unhappy and I needed to do something different.  So quit two days ago and I guess it worked out that I end with B&R this Friday, then head to TEC and SPS Huntsville and a week from this Monday I start my new job at Gig Werks.  I'm not sure what to expect or where I'm heading, but I think it's a step in the right direction.  I won't really know what kind of impact this will have on my life for at least another 6 months to a year. For some reason I can't sleep tonight and I think it's really a reflection of my last day.  Tomorrow is an ending and a beginning at the same time.  So it's both kind of sad and exciting.  I don't know why I'm really excited to go to Disney Land for the second time ever in my life time.  I get to ride the Teacups.  For the longest time when I was a kid I wanted to go to Disney Land.  I wanted to ride the teacups.  In 2007, at the age of 25, I rode the teacups for my first ever visit to LA.  That was the start of finally syncing up with my childhood goals.  I wanted to live near a major city.  I wanted to visit all the major cities in the world.  I wanted to see everything and meet everyone.  This job change will probably turn into something great I just don't know it yet.  I'm walking again outside my comfort zone and stepping into uncharted territory.  In 2-3 years I'll probably write another blog post how this week lead to something great.  It just stinks when you have to leave behind something you know and love.  I will miss all my current colleagues, but I'm sure I'll gain some new ones and keep in touch with the old.  To 2010 being a great year for change and hopefully by the end of the year I can say I went to Europe.  To reaching my goals and my dreams.  Don't let anyone stop you from getting what you want in life (unless you are axe murderer please don't kill anyone that's just wrong).  Have a good weekend everyone!

  • PayPal India Problems Continues

    - by Ravish
    Reserve Bank of India has been giving hard time to PayPal and its users in India. RBI had previously blocked PayPal transactions in India a few times, and they made it difficult to withdraw payments by enforcing exports and forex related compliance. Here is yet another bad news for Indian PayPal users. With effect from March 1st, Indian users cannot receive payments of more than $500 in your PayPal account. Moreover, you cannot keep or use any funds in your PayPal account. You can use your PayPal balance to make send money for any goods or services, and must withdraw it to your bank account within 7 days of the receipt. These changes have rendered PayPal almost useless for small business, webmasters and publishers. Most webmasters and publishers rely on PayPal to receive payments from advertisers and clients. It has also made it impossible to buy anything online with PayPal. Sending payments abroad via other channels is already a pain, sending a bank wire requires too many formalities, documentation and time. Moreover, you are even required to deduct TDS on payments you make for any products or services. The restrictions will take effect on March 1st, so you have 30 days to complete any pending transactions you may have. This step by RBI is yet another gimmick by corrupt Indian Government to make life difficult of entrepreneurs, kill innovation, slap more taxes and create more channels to take bribes. Following is the notification from PayPal about this issue: As part of our commitment to provide a high level of customer service, we would like to give you a 30-day advance notice on changes to our user agreement for India. With effect from 1 March 2011, you are required to comply with the requirements set out in the notification of the Reserve Bank of India governing the processing and settlement of export-related receipts facilitated by online payment gateways (“RBI Guidelines”). In order to comply with the RBI Guidelines, our user agreement in India will be amended for the following services as follows: Any balance in and all future payments into your PayPal account may not be used to buy goods or services and must be transferred to your bank account in India within 7 days from the receipt of confirmation from the buyer in respect of the goods or services; and Export-related payments for goods and services into your PayPal account may not exceed US$500 per transaction. We seek your understanding as we continue to employ our best efforts to comply with the RBI Guidelines in a timely manner.

  • Viewing at Impossible Angles

    - by kemer
    The picture of the little screwdriver with the Allen wrench head to the right is bound to invoke a little nostalgia for those readers who were Sun customers in the late 80s. This tool was a very popular give-away: it was essential for installing and removing Multibus (you youngsters will have to look that up on Wikipedia…) cards in our systems. Back then our mid-sized systems were gargantuan: it was routine for us to schlep around a 200 lb. desk side box and 90 lb. monitor to demo a piece of software your smart phone will run better today. We were very close to the hardware, and the first thing a new field sales systems engineer had to learn was how put together a system. If you were lucky, a grizzled service engineer might run you through the process once, then threaten your health and existence should you ever screw it up so that he had to fix it. Nowadays we make it much easier to learn the ins and outs of our hardware with simulations–3D animations–that take you through the process of putting together or replacing pieces of a system. Most recently, we have posted three sophisticated PDFs that take advantage of Acrobat 9 features to provide a really intelligent approach to documenting hardware installation and repair: Sun Fire X4800/X4800 M2 Animations for Chassis Components Sun Fire X4800/X4800 M2 Animations for Sub Assembly Module (SAM) Sun Fire X4800/X4800 M2 Animations for CMOD Download one of these documents and take a close look at it. You can view the hardware from any angle, including impossible ones. Each document has a number of procedures, that break down into steps. Click on a procedure, then a step and you will see it animated in the drawing. Of course hardware design has generally eliminated the need for things like our old giveaway tools: components snap and lock in. Often you can replace redundant units while the system is hot, but for heaven’s sake, you’ll want to verify that you can do that before you try it! Meanwhile, we can all look forward to a growing portfolio of these intelligent documents. We would love to hear what you think about them. –Kemer

  • Social Analytics and the Customer

    - by David Dorf
    Many successful retailers put the customer at the center of everything they do, so its important that the customer is modeled correctly across all their systems.  The path to omni-channel starts and ends with the customer so at ARTS, our next big project is focused on ensuring a consistent representation of customers across our transactional data model, datawarehouse model, and XML schemas.  Further, we've started a new whitepaper that describes how Big Data and Social Media Analytics should be leveraged by retailers to add and additional level of customer insight. Let's start by taking a closer look at the meaning of social analytics.  Here's my definition: Social Analytics, in the retail context, describes the analysis of data obtained from social media sources in an effort to better comprehend and interact with the community of consumers.  This discipline seeks to understand what’s being said by the community about brands and products (“monitoring”), as well as understand the behaviors of those in the community (“profiling”).  The results are used to enforce the brand image, improve product decisions, and better focus marketing, all of which lead to increased sales. To help illustrate the facets of social analytics, I drew the diagram below which was originally published by Retail Touchpoints. There are lots of tools on the market that allow retailers to monitor social media for brand and product mentions.  These include analysis of sentiment, reach, share of voice, engagement, etc.  When your brand is mentioned, good or bad, its an opportunity to engage with the customer and possibly lead to a sale.  Because products are not always unique, its much more difficult to monitor product mentions, but detecting product trends early can help a retailer make better merchandising decisions, especially in fashion. Once a retailer understands what's being said, the next step is learn more about who's saying it.  That involves profiling customers beyond simple demographics to understand their motivations.  Much can be learned from patterns, and even more when customers voluntarily share their data.  Knowing that a customer is passionate about, for example, mountain biking allows the retailer to make relevant offers on helmets, ask for opinions on hydration, and help spread marketing messages. Social analytics has many facets that benefit retailers, some of which are easy but many of which are hard.  Its important for the CMO and CIO to work closely together to plan for these capabilities and monitor the maturity of tools on the market.  This is an area that will separate winners from losers.

  • Extending Currying: Partial Functions in Javascript

    - by kerry
    Last week I posted about function currying in javascript.  This week I am taking it a step further by adding the ability to call partial functions. Suppose we have a graphing application that will pull data via Ajax and perform some calculation to update a graph.  Using a method with the signature ‘updateGraph(id,value)’. To do this, we have do something like this: 1: for(var i=0;i<objects.length;i++) { 2: Ajax.request('/some/data',{id:objects[i].id},function(json) { 3: updateGraph(json.id, json.value); 4: } 5: } This works fine.  But, using this method we need to return the id in the json response from the server.  This works fine, but is not that elegant and increase network traffic. Using partial function currying we can bind the id parameter and add the second parameter later (when returning from the asynchronous call).  To do this, we will need the updated curry method.  I have added support for sending additional parameters at runtime for curried methods. 1: Function.prototype.curry = function(scope) { 2: scope = scope || window 3: var args = []; 4: for (var i=1, len = arguments.length; i < len; ++i) { 5: args.push(arguments[i]); 6: } 7: var m = this; 8: return function() { 9: for (var i=0, len = arguments.length; i < len; ++i) { 10: args.push(arguments[i]); 11: } 12: return m.apply(scope, args); 13: }; 14: } To partially curry this method we will call the curry method with the id parameter, then the request will callback on it with just the value.  Any additional parameters are appended to the method call. 1: for(var i=0;i<objects.length;i++) { 2: var id=objects[i].id; 3: Ajax.request('/some/data',{id: id}, updateGraph.curry(id)); 4: } As you can see, partial currying gives is a very useful tool and this simple method should be a part of every developer’s toolbox.

  • ASP.NET MVC 3 Hosting :: Deploying ASP.NET MVC 3 web application to server where ASP.NET MVC 3 is not installed

    - by mbridge
    You can built sample application on ASP.NET MVC 3 for deploying it to your hosting first. To try it out first put it to web server where ASP.NET MVC 3 installed. In this posting I will tell you what files you need and where you can find them. Here are the files you need to upload to get application running on server where ASP.NET MVC 3 is not installed. Also you can deploying ASP.NET MVC 3 web application to server where ASP.NET MVC 3 is not installed like this example: you can change reference to System.Web.Helpers.dll to be the local one so it is copied to bin folder of your application. First file in this list is my web application dll and you don’t need it to get ASP.NET MVC 3 running. All other files are located at the following folder: C:\Program Files\Microsoft ASP.NET\ASP.NET Web Pages\v1.0\Assemblies\ If there are more files needed in some other scenarios then please leave me a comment here. And… don’t forget to convert the folder in IIS to application. While developing an application locally, this isn’t a problem. But when you are ready to deploy your application to a hosting provider, this might well be a problem if the hoster does not have the ASP.NET MVC assemblies installed in the GAC. Fortunately, ASP.NET MVC is still bin-deployable. If your hosting provider has ASP.NET 3.5 SP1 installed, then you’ll only need to include the MVC DLL. If your hosting provider is still on ASP.NET 3.5, then you’ll need to deploy all three. It turns out that it’s really easy to do so. Also, ASP.NET MVC runs in Medium Trust, so it should work with most hosting providers’ Medium Trust policies. It’s always possible that a hosting provider customizes their Medium Trust policy to be draconian. Deployment is easy when you know what to copy in archive for publishing your web site on ASP.NET MVC 3 or later versions. What I like to do is use the Publish feature of Visual Studio to publish to a local directory and then upload the files to my hosting provider. If your hosting provider supports FTP, you can often skip this intermediate step and publish directly to the FTP site. The first thing I do in preparation is to go to my MVC web application project and expand the References node in the project tree. Select the aforementioned three assemblies and in the Properties dialog, set Copy Local to True. Now just right click on your application and select Publish. This brings up the following Publish wizard Notice that in this example, I selected a local directory. When I hit Publish, all the files needed to deploy my app are available in the directory I chose, including the assemblies that were in the GAC.

  • A Community Cure for a String Splitting Headache

    - by Tony Davis
    A heartwarming tale of dogged perseverance and Community collaboration to solve some SQL Server string-related headaches. Michael J Swart posted a blog this week that had me smiling in recognition and agreement, describing how an inquisitive Developer or DBA deals with a problem. It's a three-step process, starting with discomfort and anxiety; a feeling that one doesn't know as much about one's chosen specialized subject as previously thought. It progresses through a phase of intense research and learning until finally one achieves breakthrough, blessed relief and renewed optimism. In this case, the discomfort was provoked by the mystery of massively high CPU when searching Unicode strings in SQL Server. Michael explored the problem via Stack Overflow, Google and Twitter #sqlhelp, finally leading to resolution and a blog post that shared what he learned. Perfect; except that sometimes you have to be prepared to share what you've learned so far, while still mired in the phase of nagging discomfort. A good recent example of this recently can be found on our own blogs. Despite being a loud advocate of the lightning fast T-SQL-based string splitting techniques, honed to near perfection over many years by Jeff Moden and others, Phil Factor retained a dogged conviction that, in theory, shredding element-based XML using XQuery ought to be even more efficient for splitting a string to create a table. After some careful testing, he found instead that the XML way performed and scaled miserably by comparison. Somewhat subdued, and with a nagging feeling that perhaps he was still missing "something", he posted his findings. What happened next was a joy to behold; the community jumped in to suggest subtle changes in approach, using an attribute-based rather than element-based XML list, and tweaking the XQuery shredding. The result was performance and scalability that surpassed all other techniques. I asked Phil how quickly he would have arrived at the real breakthrough on his own. His candid answer was "never". Both are great examples of the power of Community learning and the latter in particular the importance of being brave enough to parade one's ignorance. Perhaps Jeff Moden will accept the string-splitting gauntlet one more time. To quote the great man: you've just got to love this community! If you've an interesting tale to tell about being helped to a significant breakthrough for a problem by the community, I'd love to hear about it. Cheers, Tony.

  • TDD vs. Productivity

    - by Nairou
    In my current project (a game, in C++), I decided that I would use Test Driven Development 100% during development. In terms of code quality, this has been great. My code has never been so well designed or so bug-free. I don't cringe when viewing code I wrote a year ago at the start of the project, and I have gained a much better sense for how to structure things, not only to be more easily testable, but to be simpler to implement and use. However... it has been a year since I started the project. Granted, I can only work on it in my spare time, but TDD is still slowing me down considerably compared to what I'm used to. I read that the slower development speed gets better over time, and I definitely do think up tests a lot more easily than I used to, but I've been at it for a year now and I'm still working at a snail's pace. Each time I think about the next step that needs work, I have to stop every time and think about how I would write a test for it, to allow me to write the actual code. I'll sometimes get stuck for hours, knowing exactly what code I want to write, but not knowing how to break it down finely enough to fully cover it with tests. Other times, I'll quickly think up a dozen tests, and spend an hour writing tests to cover a tiny piece of real code that would have otherwise taken a few minutes to write. Or, after finishing the 50th test to cover a particular entity in the game and all aspects of it's creation and usage, I look at my to-do list and see the next entity to be coded, and cringe in horror at the thought of writing another 50 similar tests to get it implemented. It's gotten to the point that, looking over the progress of the last year, I'm considering abandoning TDD for the sake of "getting the damn project finished". However, giving up the code quality that came with it is not something I'm looking forward to. I'm afraid that if I stop writing tests, then I'll slip out of the habit of making the code so modular and testable. Am I perhaps doing something wrong to still be so slow at this? Are there alternatives that speed up productivity without completely losing the benefits? TAD? Less test coverage? How do other people survive TDD without killing all productivity and motivation?

  • Compute directional light frustum from view furstum points and light direction

    - by Fabian
    I'm working on a friends engine project and my task is to construct a new frustum from the light direction that overlaps the view frustum and possible shadow casters. The project already has a function that creates a frustum for this but its way to big and includes way to many casters (shadows) which can't be seen in the view frustum. Now the only parameter of this function are the normalized light direction vector and a view class which lets me extract the 8 view frustum points in world space. I don't have any additional infos about the scene. I have read some of the related Questions here but non seem to fit very well to my problem as they often just point to cascaded shadow maps. Sadly i can't use DX or openGl functions directly because this engine has a dedicated math library. From what i've read so far the steps are: Transform view frustum points into light space and find min/max x and y values (or sometimes minima and maxima of all three axis) and create a AABB using the min/max vectors. But what comes after this step? How do i transform this new AABB back to world space? What i've done so far: CVector3 Points[8], MinLight = CVector3(FLT_MAX), MaxLight = CVector3(FLT_MAX); for(int i = 0; i<8;++i){ Points[i] = Points[i] * WorldToShadowMapMatrix; MinLight = Math::Min(Points[i],MinLight); MaxLight = Math::Max(Points[i],MaxLight); } AABox box(MinLight,MaxLight); I don't think this is the right way to do it. The near plain probably has to extend into the direction of the light source to include potentional shadow casters. I've read the Microsoft article about cascaded shadow maps http://msdn.microsoft.com/en-us/library/windows/desktop/ee416307%28v=vs.85%29.aspx which also includes some sample code. But they seem to use the scenes AABB to determine the near and far plane which I can't since i cant access this information from the funtion I'm working in. Could you guys please link some example code which shows the calculation of such frustum? Thanks in advance! Additional questio: is there a way to construct a WorldToFrustum matrix that represents the above transformation?

  • SQL Server PowerShell Provider follows the Version of PowerShell on the Host and other errata

    - by BuckWoody
    There may be some misunderstanding on how the PowerShell Provider for SQL Server works. I’ve written an article or two explaining that you can use PowerShell with SQL Server, without having the SQL Server 2008 (or higher) provider around. After all, PowerShell just uses .NET, and SQL Server “Server Management Objects” or SMO listen to that interface as well. In SQL Server 2008 and higher we created a “MiniShell” for PowerShell that gives you the ability to treat a SQL Server Instance as a drive (called a “Provider” or path or drive) and a few commands (called command-lets). Using these two simple constructs you can move around SQL Server quickly and work with the objects it holds. I read the other day where someone stated that we had “re-compiled” PowerShell, so that you would have version 1.0 from SQL Server and 2.0 on your new server. Not so! Drop to a SQLPS prompt and a PowerShell prompt and type this in each: $PSVersionTable They should return the same value. You can think of a MiniShell as simply a compiled “profile” that gives you those providers and command-lets automatically – that’s all. In fact, you can load the SMO libraries yourself without the SQL Server 2008 Provider anywhere in sight. I do this all the time, since the MiniShell also has other restrictions. Also remember that if you run a PowerShell script as a SQL Agent Job step type (in 2008 and higher) that you’re running under the context of the account that starts Agent – I think most folks know this, but it’s good to keep in mind. There’s a re-written section of Books Online that goes over working with this very nicely – also covers the question “How to I connect to another server using the SQL Server PowerShell Provider” (hint: It’s just CD) and “How do I load all the SMO stuff if I don’t want to use the Provider” and more. Be sure and check out the note at the bottom that explains the firewall exceptions you’ll need to enable to CD to that remote server. Here’s that link: http://msdn.microsoft.com/en-us/library/cc281947.aspx Share this post: email it! | bookmark it! | digg it! | reddit! | kick it! | live it!

  • As a web designer, which language should I learn first for my feature career? (PHP or JavaScript) [closed]

    - by kdevs3
    Possible Duplicates: Best Programming Language for Web Development How can I choose a web development language? What language will you choose if you are going to build something big? What is the right option of programming languages and tools for building our website? What is the easiest web programing language at....? Well, I'm more of a basic web designer. I know the easy stuff pretty well. (Ya know, html, css) But I've been trying to take it to the next step and I'm contemplating about what I should learn that will help me out the most in my future web design/programming career, should it be JavaScript or maybe I should try to learn a back end programming language such as PHP. Lately, I have been hearing about a lot how JavaScript is so great and useful now, because of libraries such as jQuery and what possibility's it can bring by using Node.js and other frameworks. I've only learned the most basic of JavaScript and used some jQuery (mostly plugins) so i wouldn't know at all of what it can actually do. Would JS being so popular as it is now and useful, be a reason to stick with JavaScript and only learn it that for now? Or as a web designer, how important would it be to learn how to make a web application/website operate and functional, and know how to work with servers, etc? (Such as getting forms to work and sending data to the server and back) I've took a look at frameworks such as Code Igniter before, and looks really simple to get started with if I try to learn PHP, But I'm not sure how important it is for my career and what I would gain out of it. I'm asking because I can't decide what I should learn first. When I select it, I really want to take my time and learn the language. I don't want to spend time on learning multiple languages at the same time, so I need to pick wisely. I'm trying to turn the right direction so my career can hopefully be successful in the feature. (If money/gaining a job asked if its important, then its a yeah, it is a bit) I'm hoping I can get opinions and suggestions on this question, thanks for giving me your thoughts also.

  • OData Mix10 &ndash; Part Dos

    - by Jon Dalberg
    The other day I had a snazzy post on fetching all the video (WMV) files from Mix ‘10. A simple, console application that grabbed the urls from the OData feed and downloaded the videos. I wanted to change that app to fire the OData query asynchronously so here’s what resulted: 1: static void Main(string[] args) 2: { 3: var mix = new Mix.EventEntities(new Uri("http://api.visitmix.com/OData.svc")); 4:   5: var temp = mix.Files.Where(f => f.TypeName == "WMV"); 6: var query = temp as DataServiceQuery<Mix.File>; 7:   8: query.BeginExecute(OnFileQueryComplete, query); 9:   10: // waiting... 11: Console.ReadLine(); 12: } 13:   14: static void OnFileQueryComplete(IAsyncResult result) 15: { 16: var query = result.AsyncState as DataServiceQuery<Mix.File>; 17: var response = query.EndExecute(result); 18:   19: var web = new WebClient(); 20:   21: var myVideos = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.MyVideos), "Mix10"); 22:   23: Directory.CreateDirectory(myVideos); 24:   25: foreach (Mix.File f in response) 26: { 27: var fileName = new Uri(f.Url).Segments.Last(); 28: Console.WriteLine(f.Url); 29: web.DownloadFile(f.Url, Path.Combine(myVideos, fileName)); 30: } 31: } There are two important things here that are not explained well in the MSDN docs: See lines 5 and 6? That’s where I query for the WMV files and it returns an IQueryable<T>. You *have* to cast that to a DataServiceQuery<T> and then call BeginExecute. The documented example does not filter so it didn’t show that step. Line 16 shows the correct way to get the previously executed DataServiceQuery<T> from the async result. If you looked at the MSDN example docs it shows (incorrectly) just casting the result, like this: // wrong var query = result as DataServiceQuery<Mix.File>; Other than those items it is relatively straight forward and we’re all async-ified. Enjoy!

  • Configure Jenkins and Tomcat using Puppet on Vagrant

    - by ex3v
    I'm playing with setting up my first Spring + jenkins + Tomcat CI dev environment. For now it's just a test/fun phase, but in the near future I'll be starting new project with my coworkers. That's the reason that I want development environment virtualized and exactly te same on every development machine, as well as on production server. I choosen to use Vagrant and to try to write puppet scripts that not only install everything, but also configure everything so each of us will have the same jenkins plugins, same jenkins and tomcat login and password, and literally after calling vagrant up we are ready to work. What I managed to do so far is installation of stuff needed and port forwarding. My vagrantfile looks like this (comments stripped): VAGRANTFILE_API_VERSION = "2" Vagrant.configure(VAGRANTFILE_API_VERSION) do |config| config.vm.box = "precise32" config.vm.box_url = "http://files.vagrantup.com/precise32.box" config.vm.network :forwarded_port, guest: 80, host: 8090 config.vm.network :forwarded_port, guest: 8080, host: 8091 config.vm.network :private_network, ip: "192.168.33.10" config.vm.provision :puppet do |puppet| puppet.manifests_path = "puppet/" puppet.manifest_file = "default.pp" puppet.options = ['--verbose'] end end And this is my puppet file: Exec { path => [ "/bin/", "/sbin/" , "/usr/bin/", "/usr/sbin/" ] } class system-update { exec { 'apt-get update': command => 'apt-get update', } $sysPackages = [ "build-essential" ] package { $sysPackages: ensure => "installed", require => Exec['apt-get update'], } } class tomcat { package { "tomcat": ensure => present, require => Class["system-update"], } service { "tomcat": ensure => "running", require => Package["tomcat"], } } class jenkins { package { "jenkins": ensure => present, require => Class["system-update"], } service { "jenkins": ensure => "running", require => Package["jenkins"], } } include system-update include tomcat include jenkins Now, when I hit vagrant provision and go to http://localhost:8091/ I can see jenkins running, so above script works good. Next step is configurating jenkins and tomcat by extending above puppet scripts. I'm pretty green when it comes to CI. After wandering around web I've found few tutorials about jenkins configuration (here's one of them). I really want to move configuration presented in this tutorial to puppet file, so when I spread my vagrantfile and puppet file between my coworkers, I will be sure that everyone has exactly te same setup. Unfortunately I'm also green about using puppet, I don't know how to do this. Any help will be apreciated.

  • URL routing similar to Facebook (related to AJAX and the URL)

    - by Guilherme Cardoso
    In this article i'm gonna show you how i do when i have to update some content with AJAX and i have to change the URL. First, let's see an example to understand it better. If the user is reading a News with Id 1 and he clicked on another News with Id 2, if we update the content with AJAX the user is now reading the News Id 2 but the URL remains the same, for example: http://localhost/News/Read/1 Now let's see another example from Facebook. If i'm reading my profile and i click on Photos, Facebook updates it with AJAX and the URL switch to: http://www.facebook.com/guilhermegeek#!/guilhermegeek?sk=photos If we enter on that URL, it's mapped to: http://www.facebook.com/guilhermegeek?sk=photos The trick here is the parameters that we use after the #!. Those parameters are never sent to the server side, so we handle them on the client side (javascript).In the example of Facebook, he receives my profile name (guilhermegeek) and the action is to read photos. A few time ago i've written an article in my Portuguese blog explaining how to use an alternative to clients with javascript disabled. Like this: <a onclick="javascript:ReadNews(id);" href="#!News/Read/@id/">Title</a> When the user enter the link of that news, my function Read(); fills the News in the page. Then, i add the #!News/Read/@id/ to my URL. It's gonna stay something like this: http://localhost/News/Read/1#!News/Read/2 As i explained before, the News that the user is reading has the Id 2.The next step is to use javascript to check if the URL that the user typed has other News Id, because if we enter on the above URL our controller will get the Id 1 (everything after to the # isn't sent to the server side). $(document).ready(function () {             var h = window.location.hash;             if (h != null) {                 var parts = window.location.href.split('#!');                 if (parts.length > 1) {                     window.location.replace("http://localhost/" + parts[1]);                 }             }    }); It's pretty simple. I'm cutting everything after the #!, then i redirect the user to a new page. So, it's gonna stay:http://localhost/News/Read/2

  • Play Your Position Until the Play Breaks Down&hellip;then Do Whatever it Takes.

    - by AjarnMark
    If I didn’t know better, I would think that K. Brian Kelley (blog | twitter) has been listening in on conversations with my boss. In his recent blog post Successful Teams: Knowing When to Step Out of Your Role, Brian describes quite clearly a philosophy that my boss has been trying to get across to everyone in the department.  We have been using sports analogies, like how important it is to play your position, until the play breaks down (such as a fumble) and then do whatever it takes it to cover each other / recover the ball / win.  While we like having very skilled people who could do a lot of different tasks, it is important that you first do your assigned tasks, and only once those are complete, or failure of the larger mission is probable, do you consider walking away from them to help someone else with their responsibilities. The thing that you cannot afford, especially on a lean team, is the really nice guy who is always trying to help out other people, but in doing so, is never quite getting his own responsibilities taken care of.  Yes, if the Running Back drops the football, you want any member of the team in the vicinity to jump on it, whether that is the leading blocker or the Quarterback.  But until the fumble happens, you want the leading blocker to focus on doing his job, and block for the Running Back.  If the blocker is doing any other job than his primary responsibility, you’re probably going to lose. This sounds logical enough, but it is really easy to go astray with the best of intentions.  This is especially true on a small, tight-knit team, where it is really easy to get sucked into someone else’s task or problem, doubly so if you think you can do it better or faster than them.  Now you are really setting yourself up for failure.  The right thing is to let the other person do the job, even if it seems less efficient in the short-run, so that you can focus on the tasks which require your expertise.  Don’t break formation…don’t abandon your assignment, until it is clear that mission failure is imminent, and even then, as Brian writes, it should be with the agreement of the mission leader. Thanks, Brian, for putting it so well.  This has been distributed throughout our department.

  • Finding the Twins when Implementing Catmull-Clark subdivision using Half-Edge mesh [migrated]

    - by Ailurus
    Note: The description became a little longer than expected. Do you know a readable implementation of this algorithm using this mesh? Please let me know! I'm trying to implement Catmull-Clark subdivision using Matlab (because later on the results have to be compared with some other stuff already implemented in Matlab). First try was with a Vertex-Face mesh, the algorithm works but it is of course not very efficient (since you need neighbouring information for edges and faces). Therefore, I'm now using a Half-Edge mesh (info), see also the paper of Lutz Kettner. Wikipedia link to the idea behind Catmull-Clark SDV: Wiki. My problem lies in finding the Twin HalfEdges, I'm just not sure how to do this. Below I'm describing my thoughts on the implementation, trying to keep it concise. Half-Edge mesh (using indices to Vertices/HalfEdges/Faces): Vertex (x,y,z,Outgoing_HalfEdge) HalfEdge (HeadVertex (or TailVertex, which one should I use), Next, Face, Twin). Face (HalfEdge) To keep it simple for now, assume that every face is a quadrilateral. The actual mesh is a list of Vertices, HalfEdges and Faces. The new mesh will consist of NewVertices, NewHalfEdges and NewFaces, like this (note: Number_... is the number of ...): NumberNewVertices: Number_Faces + Number_HalfEdges/2 + Number_Vertices NumberNewHalfEdges: 4 * 4 * NumberFaces NumberNewfaces: 4 * NumberFaces Catmull-Clark: Find the FacePoint (centroid) of each Face: --> Just average the x,y,z values of the vertices, save as a NewVertex. Find the EdgePoint of each HalfEdge: --> To prevent duplicates (each HalfEdge has a Twin which would result in the same HalfEdge) --> Only calculate EdgePoints of the HalfEdge which has the lowest index of the Pair. Update old Vertices Ok, now all the new Vertices are calculated (however, their Outgoing_HalfEdge is still unknown). Next step to save the new HalfEdges and Faces. This is the part causing me problems! Loop through each old Face, there are 4 new Faces to be created (because of the quadrilateral assumption) First create the 4 new HalfEdges per New Face, starting at the FacePoint to the Edgepoint Next a new HalfEdge from the EdgePoint to an Updated Vertex Another new one from the Updated Vertex to the next EdgePoint Finally the fourth new HalfEdge from the EdgePoint back to the FacePoint. The HeadVertex of each new HalfEdge is known, the Next HalfEdge too. The Face is also known (since it is the new face you're creating!). Only the Twin HalfEdge is unknown, how should I know this? By the way, while looping through the Vertices of the new Face, assign the Outgoing_HalfEdge to the Vertices. This is probably the place to find out which HalfEdge is the Twin. Finally, after the 4 new HalfEdges are created, save the Face with the HalfVertex index the last newly created HalfVertex. I hope this is clear, if needed I can post my (obviously not-yet-finished) Matlab code.
