  • St. Louis ALT.NET

    - by Brian Schroer
    I’m a huge fan of the St. Louis .NET User Group and a regular attendee of their meetings, but always wished there was a local group that discussed more advanced .NET topics. (That’s not a criticism of the group - I appreciate that they want to server developers with a broad range of skill levels). That’s why I was thrilled when Nicholas Cloud started a St. Louis ALT.NET group in 2010. Here’s the “about us” statement from the group’s web site: The ALT.NET community is a loosely coupled, highly cohesive group of like-minded individuals who believe that the best developers do not align themselves with platforms and languages, but with principles and ideas. In 2007, David Laribee created the term "ALT.NET" to explain this "alternative" view of the Microsoft development universe--a view that challenged the "Microsoft-only" approach to software development. He distilled his thoughts into four key developer characteristics which form the basis of the ALT.NET philosophy: You're the type of developer who uses what works while keeping an eye out for a better way. You reach outside the mainstream to adopt the best of any community: Open Source, Agile, Java, Ruby, etc. You're not content with the status quo. Things can always be better expressed, more elegant and simple, more mutable, higher quality, etc. You know tools are great, but they only take you so far. It's the principles and knowledge that really matter. The best tools are those that embed the knowledge and encourage the principles (e.g. Resharper.) The St. Louis ALT.NET meetup group is a place where .NET developers can learn, share, and critique approaches to software development on the .NET stack. We cater to the highest common denominator, not the lowest, and want to help all St. Louis .NET developers achieve a superior level of software craftsmanship. I don’t see a lot of ALT.NET talk in blogs these days. The movement was harmed early on by the negative attitudes of some of its early leaders, including jerk moves like the Entity Framework “vote of no confidence”, but I do see occasional mentions of local groups like the St. Louis one. I think ALT.NET has been successful at bringing some of its ideas into the .NET world, including heavily influencing ASP.NET MVC and raising the general level of software craftsmanship for developers working on the Microsoft stack. The ideas and ideals live on, they’re just not branded as “this is ALT.NET!” In the past 18 months, St. Louis ALT.NET meetups have discussed topics like: NHibernate F# and other functional languages AOP CoffeeScript “How Ruby Is Making Me a Stronger C# Developer” Using rake for builds CQRS .NET dynamic programming micro web frameworks – Nancy & Jessica Git ALT.NET doesn’t mean (to me, anyway) “alternatives to .NET”, but “alternatives for .NET”. We look at how things are done in Ruby and other languages/platforms, but always with the idea “What can I learn from this to take back to my “day job” with .NET?”. Meetings are held at 7PM on the fourth Wednesday of each month at the offices of Professional Employment Group. PEG is located at 999 Executive Parkway (Suite 100 – lower level) in Creve Coeur (South of Olive off of Mason Road - Here's a map). Food is not supplied (sorry if you’re a big fan of the Papa John’s Crust-Lovers’ Pizza that’s a staple of user group meetings), but attendees are encouraged to come early and bring/share beer, so that’s cool. Thanks to Nick for organizing, and to Professional Employment Group for lending their offices. Please visit the meetup site for more information.

  • Sorry about the wait.

    - by Ratman21
    In the last two days have been trying remove “Iolo System Mechanic Professional” (With anti-virus and FireWall) from 3 of the 5 pc’s we have (3 lap tops and two Desk tops) as it was going to expire on the 13th.   So I could replace them with a free anti-virus (AVG) and just use the windows fire wall. I have been using the same set up on one of my desk tops (XP Pro) for 8 months and one of the Lap tops (Vista) for 5 months.   The problem was that System Mechanic did not want to go. Even after using the uninstall option on the desk top (my main PC, well its that because has the larger of all the PC’s hard drives but, is the oldest and runs XP home) and using Ccleaner to try and remove it.  It was still showing up as there and after I went a head and tried installing AVG and ran it. I found that the TCP/IP module was missing.  So no internet, I had to restore the PC back to the 1st to get the module back and then install AVG (after making sure window firewall was back on. I didn’t check that on the first try). Got the PC back to normal, very late last night. Only one of the two lap tops was easy but, even at that there are still some parts of System Mechanic on it but, AVG and firewall are working.   I may try an hunt down parts of System Mechanic on it and delete them on this lap top. Which was what finally had to do on the one of the Lap tops (also XP Home) as it would not uninstall after I restored the PC back to the 4th. So delete, delete, delete and Ccleaner (one dl file would not delete though). And I just finish installing AVG and now running a scan on the lap top. So all of this took two days (well three counting today). I started late Friday night and just finishing up now.   I only started this switch over after I had finished my Job search for day on Friday.   As for blogging on Tuesday, Wednesday and Thursday, I was busy and by the end of the day was too tired to blog, that and was hung up still on that 2nd dare of The Love Dare. So I cleaned the house, while she was out of the house. I mean, I cleaned, not just vacuumed house I cleaned the kitchen counter tops and the sinks. Did the dishes and some of the laundry over two of the those days.   As to the third day of Love Dare which is “Love is not selfish” and the dare “Whatever you put your time, energy, and money into will become more important to you. It’s hard to care for something you are not investing in. Along with restraining from negative comments, buy your spouse something that says, I was thinking of you today.”   Being on a very limited income, a lot of normal guy buying for girls is out (for one thing, the comment why did you waste our money on flowers, etc, etc, would come up. Not from me though). So that one is on hold till money issues are not a problem (no that does not mean never). The 4th day “Love is thoughtful” and the dare “Contact your spouse sometime during the business of the day. Have no agenda other than asking how he or she is doing and if there is anything you could do for them”.   I did this dare while I was still working with census last week and trying to do the dares. Well I start my CCNA classes Monday the 15th and I move on to the next Love Dare day “Love is not rude”.

  • Thoughts on Thoughts on TDD

    Brian Harry wrote a post entitled Thoughts on TDD that I thought I was going to let lie, but I find that I need to write a response. I find myself in agreement with Brian on many points in the post, but I disagree with his conclusion. Not surprisingly, I agree with the things that he likes about TDD. Focusing on the usage rather than the implementation is really important, and this is important whether you use TDD or not. And YAGNI was a big theme in my Seven Deadly Sins of Programming series. Now, on to what he doesnt like. He says that he finds it inefficient to have tests that he has to change every time he refactors. Here is where we part company. If you are having to do a lot of test rewriting (say, more than a couple of minutes work to get back to green) *often* when you are refactoring your code, I submit that either you are testing things that you dont need to test (internal details rather than external implementation), your code perhaps isnt as decoupled as it could be, or maybe you need a visit to refactorers anonymous. I also like to refactor like crazy, but as we all know, the huge downside of refactoring is that we often break things. Important things. Subtle things. Which makes refactoring risky. *Unless* we have a set of tests that have great coverage. And TDD (or Example-based Design, which I prefer as a term) gives those to us. Now, I dont know what sort of coverage Brian gets with the unit tests that he writes, but I do know that for the majority of the developers Ive worked with and I count myself in that bucket the coverage of unit tests written afterwards is considerably inferior to the coverage of unit tests that come from TDD. For me, it all comes down to the answer to the following question: How do you ensure that your code works now and will continue to work in the future? Im willing to put up with a little efficiency on the front side to get that benefit later. Its not the writing of the code thats the expensive part, its everything else that comes after. I dont think that stepping through test cases in the debugger gets you what you want. You can verify what the current behavior is, sure, and do it fairly cheaply, but you dont help the guy in the future who doesnt know what conditions were important if he has to change your code. His second part that he doesnt like backing into an architecture (go read to see what he means). Ive certainly had to work with code that was like this before, and its a nightmare the code that nobody wants to touch. But thats not at all the kind of code that you get with TDD, because if youre doing it right youre doing the write a failing tests, make it pass, refactor approach. Now, you may miss some useful refactorings and generalizations for this, but if you do, you can refactor later because you have the tests that make it safe to do so, and your code tends to be easy to refactor because the same things that make code easy to write unit tests for make it easy to refactor. I also think Brian is missing an important point. We arent all as smart as he is. Im reminded a bit of the lesson of Intentional Programming, Charles Simonyis paradigm for making programming easier. I played around with Intentional Programming when it was young, and came to the conclusion that it was a pretty good thing if you were as smart as Simonyi is, but it was pretty much a disaster if you were an average developer. In this case, TDD gives you a way to work your way into a good, flexible, and functional architecture when you dont have somebody of Brians talents to help you out. And thats a good thing.Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors? We already have over 80 articles in several categories including Silverlight.

  • Templated Razor Delegates – Phil Haack

    - by nmarun
    This post is largely based off of Phil Haack’s article titled Templated Razor Delegates. I strongly recommend reading this article first. Here’s a sample code for the same, so you can have a look at. I also have a custom type being rendered as a table. 1: // my custom type 2: public class Device 3: { 4: public int Id { get; set; } 5: public string Name { get; set; } 6: public DateTime MfgDate { get; set; } 7: } Now I can write an extension method just for this type. 1: public static class RazorExtensions 2: { 3: public static HelperResult List(this IList<Models.Device> devices, Func<Models.Device, HelperResult> template) 4: { 5: return new HelperResult(writer => 6: { 7: foreach (var device in devices) 8: { 9: template(device).WriteTo(writer); 10: } 11: }); 12: } 13: // ... 14: } Modified my view to make it a strongly typed one and included html to render my custom type collection in a table. 1: @using TemplatedRazorDelegates 2: @model System.Collections.Generic.IList<TemplatedRazorDelegates.Models.Device> 3:  4: @{ 5: ViewBag.Title = "Home Page"; 6: } 7:  8: <h2>@ViewBag.Message</h2> 9:  10: @{ 11: var items = new[] { "one", "two", "three" }; 12: IList<int> ints = new List<int> { 1, 2, 3 }; 13: } 14:  15: <ul> 16: @items.List(@<li>@item</li>) 17: </ul> 18: <ul> 19: @ints.List(@<li>@item</li>) 20: </ul> 21:  22: <table> 23: <tr><th>Id</th><th>Name</th><th>Mfg Date</th></tr> 24: @Model.List(@<tr><td>@item.Id</td><td>@item.Name</td><td>@item.MfgDate.ToShortDateString()</td></tr>) 25: </table> We get intellisense as well! Just added some items in the action method of the controller: 1: public ActionResult Index() 2: { 3: ViewBag.Message = "Welcome to ASP.NET MVC!"; 4: IList<Device> devices = new List<Device> 5: { 6: new Device {Id = 1, Name = "abc", MfgDate = new DateTime(2001, 10, 19)}, 7: new Device {Id = 2, Name = "def", MfgDate = new DateTime(2011, 1, 1)}, 8: new Device {Id = 3, Name = "ghi", MfgDate = new DateTime(2003, 3, 15)}, 9: new Device {Id = 4, Name = "jkl", MfgDate = new DateTime(2007, 6, 6)} 10: }; 11: return View(devices); 12: } Running this I get the output as: Absolutely brilliant! Thanks to both Phil Haack and to David Fowler for bringing this out to us. Download the code for this from here. Verdict: RazorViewEngine.Points += 1;

  • How do you educate your teammates without seeming condescending or superior?

    - by Dan Tao
    I work with three other guys; I'll call them Adam, Brian, and Chris. Adam and Brian are bright guys. Give them a problem; they will figure out a way to solve it. When it comes to OOP, though, they know very little about it and aren't particularly interested in learning. Pure procedural code is their MO. Chris, on the other hand, is an OOP guy all the way -- and a cocky, condescending one at that. He is constantly criticizing the work Adam and Brian do and talking to me as if I must share his disdain for the two of them. When I say that Adam and Brian aren't interested in learning about OOP, I suspect Chris is the primary reason. This hasn't bothered me too much for the most part, but there have been times when, looking at some code Adam or Brian wrote, it has pained me to think about how a problem could have been solved so simply using inheritance or some other OOP concept instead of the unmaintainable mess of 1,000 lines of code that ended up being written instead. And now that the company is starting a rather ambitious new project, with Adam assigned to the task of getting the core functionality in place, I fear the result. Really, I just want to help these guys out. But I know that if I come across as just another holier-than-thou developer like Chris, it's going to be massively counterproductive. I've considered: Team code reviews -- everybody reviews everybody's code. This way no one person is really in a position to look down on anyone else; besides, I know I could learn plenty from the other members on the team as well. But this would be time-consuming, and with such a small team, I have trouble picturing it gaining much traction as a team practice. Periodic e-mails to the team -- this would entail me sending out an e-mail every now and then discussing some concept that, based on my observation, at least one team member would benefit from learning about. The downside to this approach is I do think it could easily make me come across as a self-appointed expert. Keeping a blog -- I already do this, actually; but so far my blog has been more about esoteric little programming tidbits than straightforward practical advice. And anyway, I suspect it would get old pretty fast if I were constantly telling my coworkers, "Hey guys, remember to check out my new blog post!" This question doesn't need to be specifically about OOP or any particular programming paradigm or technology. I just want to know: how have you found success in teaching new concepts to your coworkers without seeming like a condescending know-it-all? It's pretty clear to me there isn't going to be a sure-fire answer, but any helpful advice (including methods that have worked as well as those that have proved ineffective or even backfired) would be greatly appreciated. UPDATE: I am not the Team Lead on this team. Chris is. UPDATE 2: Made community wiki to accord with the general sentiment of the community (fancy that).

How can they address all these areas with one comprehensive strategy? With enterprise project portfolio management solutions that provide greater transparency and visibility across all projects and portfolios, says Guy Barlow, Oracle director of industry strategy. In the following interview and in an exclusive, three-part webcast series, Barlow examines today’s new management realities and explains how organizations can succeed in this environment. Q: Financial discipline has always been important, what’s different today? A: A number of organizations are showing that by fiscally aligning projects with the business goals of their organizations, they can shave off hundreds of thousands if not millions of dollars in inefficiency and waste. For example, one Oracle customer, the Columbus Regional Airport Authority, reduced its unbudgeted costs from US$24.4 million to US$3.5 million, for an 88 percent improvement. Q: How do organizations achieve results like this? A: First, they need to have the vision to see project management as part of a broad and critical element in their overall enterprise strategy. That means using a single solution, such as Oracle‘s Primavera, to manage multiple projects across multiple functions within a company. So someone in corporate mergers and acquisitions as well as a capital projects team can standardize on the same technology. By doing so they all gain greater efficiency in planning and execution—because the technology can be configured for their specific roles and needs—and the IT organization really benefits from lower maintenance. Second, enterprises must give executive leaders—CFOs, COOs, and CEOs—visibility across the entire business to easily see what projects are on track and which ones are falling behind. In fact, once executives see the power of enterprise project portfolio management, uptake is very quick across the organization. Read the full interview here.

  • Announcing Oracle Knowledge 8.5: Even Superheroes Need Upgrades

    - by Richard Lefebvre
    It’s no secret that we like Iron Man here at Oracle. We've certainly got stuff in common: one of the world’s largest technology companies and one of the world’s strongest technology-driven superheroes. If you've seen the recent Iron Man movies, you might have even noticed some of our servers sitting in Tony Stark’s lab. Heck, our CEO made a cameo appearance in one of the movies. Yeah, we’re fans. Especially as Iron Man is a regular guy with some amazing technology – like us. But Like all great things even Superheroes need upgrades, whether it’s their suit, their car or their spacestation. Oracle certainly has its share of advanced technology.  For example, Oracle acquired InQuira in 2011 after years of watching the company advance the science of Knowledge Management.  And it was some extremely super technology.  At that time, Forrester’s Kate Leggett wrote about it in ‘Standalone Knowledge Management Is Dead With Oracle's Announcement To Acquire InQuira’ saying ‘Knowledge, accessible via web self-service or agent UIs, is a critical customer service component for industries fielding repetitive questions about policies, procedures, products, and solutions.’  One short sentence that amounts to a very tall order.  Since the acquisition our KM scientists have been hard at work in their labs. Today Oracle announced its first major knowledge management release since its acquisition of InQuira: Oracle Knowledge 8.5. We’ve put a massively-upgraded supersuit on our KM solution because we still have bad guys to fight. And we are very proud to say that we went way beyond our original plans. So what, exactly, did we do in Oracle Knowledge 8.5? We did what any high-tech super-scientist would do. We made Oracle Knowledge smarter, stronger and faster. First, we gave Oracle Knowledge a stronger heart: Certified on Oracle technologies, including Oracle WebLogic Server, Oracle Business Intelligence, Oracle Exadata Database Machine and Oracle Exalogic Elastic Cloud. Huge scaling and performance improvements. Then we gave it a better reach: Improved iConnect functionality that delivers contextualized knowledge directly into CRM applications. Better content acquisition support across disparate sources. Enhanced Language Support including Natural Language search support for 16 Languages. Enhanced Keyword Search for 23 authoring languages, as well as enhanced out-of-the-box industry ontologies covering 14 languages. And finally we made Oracle Knowledge ridiculously smarter: Improved Natural Language Search and a new Contextual Answer Delivery that understands the true intent of each inquiry to deliver the best possible answers. AnswerFlow for Guided Navigation & Answer Delivery, a new application for guided troubleshooting and answer delivery. Knowledge Analytics standardized on Oracle’s Business Intelligence Enterprise Edition. Knowledge Analytics Dashboards optimized search and content creation through targeted, actionable insights. A new three-level language model "Global - Language - Locale" that provides an improved search experience for organizations with a global footprint. We believe that Oracle Knowledge 8.5 is the most sophisticated KM solution in existence today and we’ve worked very hard to help it fulfill the promise of KM: empowering customers and employees with deep insights wherever they need them. We hope you agree it’s a suit worth wearing. We are continuing to invest in Knowledge Management as it continues to be especially relevant today with the enterprise push for peer collaboration, crowd-sourced wisdom, agile innovation, social interaction channels, applied real-time analytics, and personalization. In fact, we believe that Knowledge Management is a critical part of the Customer Experience portfolio for success. From empowering employee’s, to empowering customers, to gaining the insights from interactions across all channels, businesses today cannot efficiently scale their efforts, strengthen their customer relationships or achieve their growth goals without a solid Knowledge Management foundation to build from. And like every good superhero saga, we’re not even close to being finished. Next we are taking Oracle Knowledge into the Cloud. Yes, we’re thinking what you’re thinking: ROCKET BOOTS! Stay tuned for the next adventure… By Nav Chakravarti, Vice-President, Product Management, CRM Knowledge and previously the CTO of InQuira, a knowledge management company acquired by Oracle in 2011

  • What Counts For a DBA – Decisions

    - by Louis Davidson
    It’s Friday afternoon, and the lead DBA, a very talented guy, is getting ready to head out for two well-earned weeks of vacation, with his family, when this error message pops up in his inbox: Msg 211, Level 23, State 51, Line 1. Possible schema corruption. Run DBCC CHECKCATALOG. His heart sinks. It’s ten…no eight…minutes till it’s time to walk out the door. He glances around at his coworkers, competent to handle many problems, but probably not up to the challenge of fixing possible database corruption. What does he do? After a few agonizing moments of indecision, he clicks shut his laptop. He’ll just wait and see. It was unlikely to come to anything; after all, it did say “possible” schema corruption, not definite. In that moment, his fate was sealed. The start of the solution to the problem (run DBCC CHECKCATALOG) had been right there in the error message. Had he done this, or at least took two of those eight minutes to delegate the task to a coworker, then he wouldn’t have ended up spending two-thirds of an idyllic vacation (for the rest of the family, at least) dealing with a problem that got consistently worse as the weekend progressed until the entire system was down. When I told this story to a friend of mine, an opera fan, he smiled and said it described the basic plotline of almost every opera or ‘Greek Tragedy’ ever written. The particular joy in opera, he told me, isn’t the warbly voiced leading ladies, or the plump middle-aged romantic leads, or even the music. No, what packs the opera houses in Italy is the drama of characters who, by the very nature of their life-experiences and emotional baggage, make all sorts of bad choices when faced with ordinary decisions, and so move inexorably to their fate. The audience is gripped by the spectacle of exotic characters doomed by their inability to see the obvious. I confess, my personal experience with opera is limited to Bugs Bunny in “What’s Opera, Doc?” (Elmer Fudd is a great example of a bad decision maker, if ever one existed), but I was struck by my friend’s analogy. If all the DBA cubicles were a stage, I think we would hear many similarly tragic tales, played out to music: “Error handling? We write our code to never experience errors, so nah…“ “Backups failed today, but it’s okay, we’ll back up tomorrow (we’ll back up tomorrow)“ And similarly, they would leave their audience gasping, not necessarily at the beauty of the music, or poetry of the lyrics, but at the inevitable, grisly fate of the protagonists. If you choose not to use proper error handling, or if you choose to skip a backup because, hey, you haven’t had a server crash in 10 years, then inevitably, in that moment you expected to be enjoying a vacation, or a football game, with your family and friends, you will instead be sitting in front of a computer screen, paying for your poor choices. Tragedies are very much part of IT. Most of a DBA’s day to day work has limited potential to wreak havoc; paperwork, timesheets, random anonymous threats to developers, routine maintenance and whatnot. However, just occasionally, you, as a DBA, will face one of those decisions that really matter, and which has the possibility to greatly affect your future and the future of your user’s data. Make those decisions count, and you’ll avoid the tragic fate of many an operatic hero or villain.

  • SQLAuthority News – Who I Am And How I Got Here – True Story as Blog Post

    - by pinaldave
    Here are few of the sample questions I get every day? “Give me shortcut to become superstar?” “How do I become like you?” “Which book I should read so I know everything?” “Can you share your secret to be successful? I want to know it but do not share with others.” There is generic answer I always give is to work hard and read good educational material or watch good online videos. One of the emails really caught my attention. It was from a friend and SQL Server Expert John Sansom (Blog | Twitter). He wrote if I would like to share my story with the world about “Who I am and How I got Here”. I was very much intrigued with his suggestion. John is one guy I respect a lot. Every single topic he writes, I read it with dedication. I eagerly wait for his Weekly Summary of Best SQL Links. If you have not read them, you are missing something out. Writing a guest post for him was like walking in memory lane. I remembered the time when I was beginning my career and I was bit overconfident and bit naive. I had my share of mistakes when I started my career. As time passed by I realize the truth. Well, we all do mistakes. Though, I am proud that as soon as I know my mistakes I corrected them. I never acted on impulse or when I am angry. I think that alone has helped me analysis the situation better and become better human being. During the course, I have lost my ego and it is replaced by passion. I am much more happy and successful in my work. Quite often people ask me if I am always online and wether I have family or not. Honestly, I am able to work hard because of my family. They support me and they encourage me to be enjoy in what I do. They support everything I do and personally, I do not miss a single occasion to join them in daily chores of fun. If there was a shortcut to success – I want know.

  • So You Want to Be a Social Media Director

    - by Mike Stiles
    Do you want to be a Social Media Director? Some say the title is already losing its relevance; that social should be a basic skill that is required and used no matter what your position is inside the enterprise. I suppose that’s visionary, and a fun thing for thought leaders to say. But in the vast majority of business organizations, we’re so far away from that reality that the thought of not having someone driving social’s implementation and guiding its proper usage conjures up images of anarchy. That said, social media has become so broad, so catch-all, and so extended across business functions, that today’s Social Media Director, depending on the size of their staff, must make jacks-of-all-trades look like one-trick-ponies. Just as the purview of the CMO has grown all-encompassing, the disciplines required of their heads of social are stacking up. Master of Content Every social pipeline you build must stay filled, with quantity and quality. Content takes time, and the job never stops. Never. And no, it’s not true that anybody can write. Master of Customer Experience You must have a passion for hearing from customers and making them really happy. Master of PR You must know how to communicate and leverage the trust you’ve built when crises strike. Couldn’t hurt to be a Master of Politics. Master of Social Technology So many social management tools on the market. You have to know what social tech ecosystem makes sense and avoid piecemeal point solutions. Master of Business Development Social for selling and prospecting is hot, and you have to know how to use social to do it. Master of Analytics Nothing else matters if you can’t prove social is helping the brand. That’s right, creative content guy has to also be a math and stats geek. Good luck with that. Master of Paid Media You’ve got to learn the language, learn the tactics, learn the vendors and learn how to measure results. Master of Education Guess who gets to teach everyone who has no clue how to use social for business. Master of Personal Likability You’ll be leading the voice, tone, image and personality of the brand. If you don’t instinctively know how to be liked by actual people, the brand will be starting from a deficit. How deep must you go in this parade of masteries? Again, that depends on your employer’s maturity level in social. Serious players recognize these as distinct disciplines requiring true experts for maximum effect. Less serious players will need you to execute personally in many of these areas. Do the best you can, and try to grow quickly at each. If you’re the sole person executing all social…well…you’re in the game of managing expectations and trying to socially educate your employer. The good news is, you should be making a certifiable killing. If you’re alone and your salary is modest, time to understand how many brands out there crave what you’ve mastered. Not to push back against thought leaders, but the need for brand social leadership has not gone away…not even a little bit. @mikestiles @oraclesocialPhoto: Stefan Wagner, freeimages.com

  • How do developer get rid of silly requirements?

    - by sugar
    Hmm ! First of all let me give you the note of the requirement. So that you can have idea what kind of problem I am facing. Words From Project Manager : Hey ! Sugar, I am assigning you a task for developing a framework. This framework is supposed to be developed for all iOS application. Please go through brief of the required framework. It should be able to detect the thickness of my Thumb. It should be able to detect whether User is using thumb or Fingers If user is using thumbs/Fingers, Framework should calculate the size of thumb/fingers. Once size is been calculated, all elements of user interface should arranged & resized automatically. ( not specified how & where as its framework - it should be smart enough to arrange automatically ) If thumb size is larger elements should get arranged near by center area of iPad/iPhone If thumb size is smaller elements should get arranged near by corners of iPad/iPhone If thumb size is larger, fonts of all elements should get smaller. ( assuming = aged person ) If thumb size is smaller, fonts of all elements should get larger. ( assuming smaller thumb = low aged person ) Summary : This framework is required for creating user-friendly user-interfaces programmatically. We need to develop a very developer-friendly framework. Framework should be developed in such a way that we can use in as many projects as needed. Well, I am a developer. What I want to have as an answer is as follows. How to describe them - the way of they thinking is bit ridiculous ? How do I explain them - we can better concentrate on developing actual projects ? How do I convince them - that this kind of things even if possible, is not recommended to develop such things ? How do I say politely, gently & respectfully NO to this ? What should I say, So that they can not point at my experience ? ( e.g. you are 3 years experienced guy & you must have abilities to develop such things ) Feeling horror. Please help. Thanks in advance, Sugar. Note : Please help me to tag this question properly. I am stuck & this is real situation. Frustrated & tensed. You guys might have faced such requirements from TopLevel. requesting you to help with your experience. Well ! I came to know that - those TOPLEVEL guys don't have any idea of iPad, iPhone, Apple etc. I would do one thing. Sir, before we go further for framework development. It is strongly recommended to read Apple Human Interface Guidlines.

  • Strange Happenings

    - by MOSSLover
    There are weeks we go about our life thinking nothing is going to change nothing will happen.  Then there are other weeks a billion things happen at once.  Friday started off very weird for me.  I flew into Atlanta and I met some cool people for another SharePoint event.  I had some good conversations.  Saturday then hit me and my virtual machine bombed in my presentation after the auto updater ran.  I was writing code on the board and describing everything in notepad.  I would say as presentations go it was the best and the worst presentation all wrapped into one.  The next day I was in Baltimore and I hung out with my aunt which was relatively uneventful and great.  Then Monday hit and half my presentations failed or succeeded and my screen freezes so I start describing the code.  I was on top of my game until Monday night.  On top of the world.  I'm exhausted I get into Raleigh and one of the craziest stories of my life happens.  So my boss has been renting cars through Priceline this week I got a different company than the other weeks. The company gives me a Ford Focus and I plug in the coordinates on my IPhone where I want go.  I head out and then I get to the destination hotel (or I thought I did). I go inside it's the wrong hotel the other one is a few miles away.  I walk outside hop into the car and it sounds like a gunshot.  Nothing is starting...Am I doing something wrong?  No I'm not the car is completely dead in the water.  I call the rental car facility and they tell me to call roadside they are closing for the night.  Roadside says they can't give me a new car but they can get me a jump then I have to take it up with the facility.  They send me a tow truck to give me a jump the guy can't jump the car.  He tells me this vehicle was towed about an hour ago.  He shows me a copy of a slip from when he towed it.  We also notice the rental car company left one of there price scanning guns in the vehicle.  I call up roadside and now they are interested in getting me a car because I need to be onsite tomorrow.  They get the manager of the facility on the phone he apologizes profusely and he says he'll be there in 10 minutes.  About 30 minutes pass and him plus another dude show up with a Ford Escape leather interior.  At this point I hand him the gun tell him someone left it in the vehicle and that I'm not so happy with them.  I ask them to comp my rental they can't due to Priceline, however if I call him again this week he can get me a voucher.  It's about 2 am and I'm ready to get to the hotel I don't make it in the next morning until 10 am.  I would say this was a crazy week all forms of technology are trying to tell me something.  What I have no idea, but we'll see the outcome soon.  I feel so weird tons of change is about to happen.  I don't know if it's good or bad.  I think this week is some form of omen.

  • C#: A "Dumbed-Down" C++?

    - by James Michael Hare
    I was spending a lovely day this last weekend watching my sons play outside in one of the better weekends we've had here in Saint Louis for quite some time, and whilst watching them and making sure no limbs were broken or eyes poked out with sticks and other various potential injuries, I was perusing (in the correct sense of the word) this month's MSDN magazine to get a sense of the latest VS2010 features in both IDE and in languages. When I got to the back pages, I saw a wonderful article by David S. Platt entitled, "In Praise of Dumbing Down"  (msdn.microsoft.com/en-us/magazine/ee336129.aspx).  The title captivated me and I read it and found myself agreeing with it completely especially as it related to my first post on divorcing C++ as my favorite language. Unfortunately, as Mr. Platt mentions, the term dumbing-down has negative connotations, but is really and truly a good thing.  You are, in essence, taking something that is extremely complex and reducing it to something that is much easier to use and far less error prone.  Adding safeties to power tools and anti-kick mechanisms to chainsaws are in some sense "dumbing them down" to the common user -- but that also makes them safer and more accessible for the common user.  This was exactly my point with C++ and C#.  I did not mean to infer that C++ was not a useful or good language, but that in a very high percentage of cases, is too complex and error prone for the job at hand. Choosing the correct programming language for a job is a lot like choosing any other tool for a task.  For example: if I want to dig a French drain in my lawn, I can attempt to use a huge tractor-like backhoe and the job would be done far quicker than if I would dig it by hand.  I can't deny that the backhoe has the raw power and speed to perform.  But you also cannot deny that my chances of injury or chances of severing utility lines or other resources climb at an exponential rate inverse to the amount of training I may have on that machinery. Is C++ a powerful tool?  Oh yes, and it's great for those tasks where speed and performance are paramount.  But for most of us, it's the wrong tool.  And keep in mind, I say this even though I have 17 years of experience in using it and feel myself highly adept in utilizing its features both in the standard libraries, the STL, and in supplemental libraries such as BOOST.  Which, although greatly help with adding powerful features quickly, do very little to curb the relative dangers of the language. So, you may say, the fault is in the developer, that if the developer had some higher skills or if we only hired C++ experts this would not be an issue.  Now, I will concede there is some truth to this.  Obviously, the higher skilled C++ developers you hire the better the chance they will produce highly performant and error-free code.  However, what good is that to the average developer who cannot afford a full stable of C++ experts? That's my point with C#:  It's like a kinder, gentler C++.  It gives you nearly the same speed, and in many ways even more power than C++, and it gives you a much softer cushion for novices to fall against if they code less-than-optimally.  A bug is a bug, of course, in any language, but C# does a good job of hiding and taking on the task of handling almost all of the resource issues that make C++ so tricky.  For my money, C# is much more maintainable, more feature-rich, second only slightly in performance, faster to market, and -- last but not least -- safer and easier to use.  That's why, where I work, I much prefer to see the developers moving to C#.  The quantity of bugs is much lower, and we don't need to hire "experts" to achieve the same results since the language itself handles those resource pitfalls so prevalent in poorly written C++ code.  C++ will still have its place in the world, and I'm sure I'll still use it now and again where it is truly the correct tool for the job, but for nearly every other project C# is a wonderfully "dumbed-down" version of C++ -- in the very best sense -- and to me, that's the smart choice.

  • Live vom Oracle Partner Day 2012 in Frankfurt

    - by A&C Redaktion
    Frankfurt a. M. gegen 11:30 UhrCharmante Idee, mit einem Welcome-Lunch in den Oracle Partner Day 2012 zu starten. So kann man bei einem Snack auch gleich die beeindruckende Atmosphäre der Commerzbank Arena auf sich wirken lassen und ist, ehe man sich versieht, mit dem nebenstehenden Geschäftsführer, einer Managerin und zwei Vertriebsmitarbeitern in ein Gespräch über die jeweils letzten Stadionbesuche verwickelt. Überall fröhliches Wiedersehen, viele haben sich das letzte Mal vor genau einem Jahr getroffen, im Radisson Blu, beim OPN Day Satellite. So, die Masse setzt sich in Bewegung – auf geht’s zur Eröffnung: Silvia Kaske fängt an! 13:45 Uhr Die Keynotes waren mal wieder ein thematischer Rundumschlag – und ein kleines Who-is-Who im Oracle Universum zugleich: Silvia Kaske, Senior Director Channel A&C eröffnete den Partner Day, danach stellte David Callaghan (Senior Vice President UK, Ireland, Israel) die EMEA-Strategien für das FY13 vor und Jürgen Kunz (SVP Technology Northern Europe & Country Leader Germany) sprach über die Geschäftsmöglichkeiten mit Partnern. Christian Werner gab in seiner neuen Funktion als Senior Director Alliances & Channels Germany einen Überblick über die neue Struktur des Oracle Channels und stellte das deutsche Team vor. Zum Abschluss folgte mit Prof. Hermann Maurer ein Gastredner von der Academia Europaea, einer prominent besetzten akademischen Gesellschaft, die sich dem besseren Verständnis der Wissenschaft in der Öffentlichkeit verschrieben hat. Er wagte einen Blick in die Zukunft der IT: „Das Beste kommt erst noch“. Wie immer, in einem so komprimierten Programm, bleibt noch die eine oder andere Frage – aber jetzt ist ja Zeit, bei Coffee & Networking noch mal nachzufragen. Kurz nach 14 Uhr Viele haben inzwischen auch das erste Obergeschoss erkundet. In der Partner Service Zone ist das Angebot breit gefächert: Von Oracle Financing über das License Management bis hin zu OPN Specialized dreht sich hier alles um konkrete Angebote für Partner. Nach einem kurzen Abstecher in die ISV-Lounge, geht es weiter zur Expert Zone: Oracle Database, Oracle Options, Fusion Middleware, Applications und Oracle Hardware heißen hier die Themen und an den Infoständen wird bereits lautstark gefachsimpelt. Zurück im Erdgeschoss sieht man noch diverse Partner, Oracle Executives und andere Teilnehmer durcheinander wuseln, um ihre Breakout Session zu finden. Andere blättern im druckfrischen A&C Kursbuch. In den nächsten zwei Stunden stehen Business Opportunities im Fokus – aufgeteilt nach Hardware, Technology oder Sales Partnern – dazu noch die Angebote der VADs, die A&C Partner Sessions und das 1:1 Speed Dating. Einige Partner nutzen parallel die angebotenen Implementation Tests, um direkt vor Ort die Zertifizierung zu erhalten. Das doppelte Angebot der Breakouts ermöglicht den Teilnehmern, an möglichst vielen Sessions nacheinander teilzunehmen. Kein Thema soll zu kurz kommen! Ein AusblickWas erwartet uns noch, im Laufe des Nachmittags? Sehr informativ wird sicherlich das Leader Panel, in dem die teilnehmenden Partner Fragen an Oracle Executives stellen können. Wenn dann die ersten Teilnehmer unruhig werden, hat das nichts mit den Themen zu tun. Nein, es steht vielmehr noch ein spannender Höhepunkt bevor: die Partner Award Ceremony (über die wir später ausführlich berichten werden). Nach einer hoffentlich gelungenen Veranstaltung stellt sich zum Schluss nur noch die Frage, was sich genau hinter der „Red Stack Arena Sports Challenge“ verbirgt. Brauchen wir Turnschuhe?

  • Dissing Architects, or "What's wrong with the coffee?"

    - by Bob Rhubart
    In my conversations with people in architect roles, tales of animosity, disrespect, and outright hostility aren't uncommon. And it's clear that in more than a few organizations architects regularly face a tough uphill climb. For architects with the requisite combination of technical, organizational, and people skills, that rough treatment is grossly undeserved. But tales of unqualified people in positions up and down the IT food chain are also easy to come by. So what's the other side of the architect story? Are some architects tarnishing the role and making life miserable for their more qualified colleagues? The various quotes included below were culled from a variety of sources. The criticism is harsh, and the people behind these quotes clearly have issues with architects. Still, whether based on mere opinion or actual experience, the comments shed some light on behaviors that should raise red flags for anyone pursuing a career as an architect. If you're an architect, and you've ever noticed that your coffee tastes like window cleaner, or your car is repeatedly keyed, or no one ever holds the elevator for you, maybe you need to do a little soul searching... Those Who Can, Code; Those Who Can't, Architect | Joe Winchester [May 18, 2007] "At the moment there seems to be an extremely unhealthy obsession in software with the concept of architecture. A colleague of mine, a recent graduate, told me he wished to become a software architect. He was drawn to the glamour of being able to come up with grandiose ideas - sweeping generalized designs, creating presentations to audiences of acronym addicts, writing esoteric academic papers, speaking at conferences attended by headless engineers on company expense accounts hungrily seeking out this year's grail, and creating e-mails with huge cc lists from people whose signature footer is more interesting than the content. I tried to re-orient him into actually doing some coding, to join a team that has a good product and keen users both of whom are pushing requirements forward, to no avail. Somehow the lure of being an architecture astronaut was too strong and I lost him to the dark side." Don't Let Architecture Astronauts Scare You | Joel Spolsky [April 21, 2001] "It's very hard to get them to write code or design programs, because they won't stop thinking about Architecture. They're astronauts because they are above the oxygen level, I don't know how they're breathing. They tend to work for really big companies that can afford to have lots of unproductive people with really advanced degrees that don't contribute to the bottom line. Remember that the architecture people are solving problems that they think they can solve, not problems which are useful to solve." Non Coding Architects Suck | Richard Henderson [May 24, 2010] "If a guy with a badge saying 'system architect' looks blank on low-level issues then he is not an architect, he is a business-analyst who went on a course. He will probably wax lyrical on all things high-level and 'important.' He will produce lovely object hierarchies without a clue to implementation. He will have a moustache and play golf." Architects Play Golf | Sunir Shah [August 15, 2012] "Often arrogant architects are difficult to get a hold of during the implementation phase because they no longer feel the need to stick around. Especially around midnight when most of the poor sob [sic] developers are still banging away. After all, they've already solved the problem--the rest is just an implementation exercise." Engineer vs Architect(Part of a discussion on the IT Architect Network Group on LinkedIn) "[An] architect spends his time producing white papers full of acronyms he does not understand but that impress his boss [while the] engineer keeps his head down and does the actual job." Architects Don't Code | [Author Unknown] "Faulty belief: System Architects don't need to code anymore. They know what they are talking about by virtue of the fact that they are System Architects."

  • 13 Things From the Oracle Social Summit You Should Know

    - by Mike Stiles
    Oracle held its first annual Oracle Social Summit, “The School for the Socially Gifted,” this past week in Las Vegas.  If anyone came to the event uncertain as to why Oracle has such an interest in social, and what its plans for social are, they left with an entirely new vision of where social is headed, and why.For those unable to attend, I was able to keep my MacBook charged just long enough to capture some of the more pertinent takeaways.1. The social enterprise is inevitable.  Social technology is disrupting the hierarchies of big companies.  It’s a revolution in corporate structures, just as it has been in various governments.  It’s not crazy to ask yourself if your CEO is the next Mubarak.  (David Kilpatrick Author of “The Facebook Effect” and founder of the Techonomy Conference) 2. The social enterprise represents collaboration on steroids.  It’s tapping into the power of your people, as opposed to keeping them “in their place.”  3. 1 in every 7 humans on earth is an active Facebook user.  75% have posted a negative comment after a poor customer experience.  The average user will inform 53 people of a bad experience.4. Checking social media is the 2nd biggest use of phones now.  Reading posts from brands is 4th.5. 70% of marketers have little or no understanding of the social conversations happening around their brand.6. Advertising, when done well, is content we care about, preferably informed by those we trust.7. Acquiring low-quality fans through gimmicks, or focusing purely on fan acquisition is a mistake.  And relying purely on organic distribution is a mistake.  (John Yi, Head of Marketing Partnerships – Facebook)8. Using all this newfound data and insight serves to positively affect the customer experience.  It allows organizations to now leverage the investments they’ve made in social up to now.9. Social is not a marketing utopia where everything is free.  It’s pay to play.  The paid component is about driving attention.  10. We are only in the infancy of ad-targeting opportunities in social.  There’s an evolution underway from interest-based targeting to action-based targeting.11. There’s actually very little overlap of the people following you on different social platforms.  Don’t assume it’s the same audience on each.12. People who can create content and who also have an understanding of what drives that content are growing increasingly valuable.13. Oracle Social’s future is enterprise SRM, integrated across marketing, selling, service, HR and every other corner of the organization.And in case you thought those were the only gems to come out of the summit, you may want to keep an eye out for Tuesday’s Social Spotlight, ever so aptly titled “13 More Things from the Oracle Social Summit You Should Know.”

  • Is there an IDE that can simplify the process of creating a game matchmaking website?

    - by Scott
    Yes, I'm an old guy. And I'm well versed in "C" and have written several games which I have been selling on the web for a number of years. And now, I would like to adapt one of my games to be "online". Sounds simple. I'm sure I can use the thousands of lines of "C" code that I've already written. Right? So my initial investigation begins. First, I think I'll need a server program that lives on a dedicated server (or a VPS probably) that talks to a bunch of client applications that live on individual devices around the world. I can certainly handle that! (I think to myself). I'll break up my existing game into two pieces, a client piece that is just the game displays and buttons, and a server piece that does everything else. Piece of cake, right? But that means that the "server piece" must be executed on a remote machine somewhere and run 24/7. Can I do that? [apparently, that question is so basic, so uneducated, and so lame, that nobody has ever posed it before. Because hours of Googling does not yield an answer. Fine. I'll assume I can do that and move on.] I'll need a "game room", which to me means a website where you log in and then go to a lobby of some kind where you can setup your preferences, see if any of your friends are connected, and create or join games. Should be easy, but it's not. No way. Can I do all this with my local website builder? (which happens to be 90 Second Website Builder, a nice product, btw). It turns out, I can not. I can start with that, but must modify each page, so I can interact with my sql database. So I begin making each page a "PHP" page and dynamically modifying the HTML code with PHP code. I'm already starting to get a headache. Because the resulting web pages looked terrible, I began looking at using JQuery. I want to user a JQuery dialog on my website to display a list of friends and allow the user to select one to invite to the game. [google search for "how to populate a JQuery dialog from a sql database" yields nothing but more confusion.] Javascript? Java? HTML? XML? HTML5? PHP? JQuery? Flash? Sockets? Forms? CSS? Learning about each one of these, and how they interact with each other and/or depend on each other is too much for my feeble old brain. Can anyone simplify this process for me? Is there an IDE that will help me do all this without having to go back to college for a few years? Thanks, Scott

    The Top 10 most-viewed items shared on the OTN ArchBeat Facebook page for the week of September 9-15, 2017. 15 Lessons from 15 Years as a Software Architect | Ingo Rammer In this presentation from the GOTO Conference in Copenhagen, Ingo Rammer shares 15 tips regarding people, complexity and technology that he learned doing software architecture for 15 years. Attend OTN Architect Day – by Architects, for Architects – October 25 You won't need 3D glasses to take in these live presentations (8 sessions, two tracks) on Cloud computing, SOA, and engineered systems. And the ticket price is: Zero. Nothing. Absolutely free. Register now for Oracle Technology Network Architect Day in Los Angeles. Thursday October 25, 2012, 8:00 a.m. – 5:00 p.m. Sofitel Los Angeles , 8555 Beverly Boulevard , Los Angeles, CA 90048. Cloud API and service designers, stop thinking small | Cloud Computing - InfoWorld "The focus must shift away from fine-grained APIs that provide some type of primitive service, such as pushing data to a block of storage or perhaps making a request to a cloud-rooted database," says InfoWorld's David Linthicum. "To go beyond primitives, you must understand how these services should be used in a much larger architectural context. In other words, you need to understand how businesses will employ these services to form real workplace solutions—inside and outside the enterprise." Adding a runtime picker to a taskflow parameter in WebCenter | Yannick Ongena Oracle ACE Yannick Ongena shows how to create an Oracle WebCenter popup to allow users to "select items or do more complex things." Oracle IAM 11g R2 docs are now available "One of the great things about the new doc set is the inclusion of ePub files," says Fusion Middleware A-Team blogger Chris Johnson. "This means that if you have an iPad you can load up the doc library onto that and read the docs on the couch." Setting up a local Yum Server using the Exalogic ZFS Storage Appliance | Donald A concise technical post from the man named Donald. What's New in Oracle VM VirtualBox 4.2? | The Fat Bloke Sings "One of the trends we've seen is that as the average host platform becomes more powerful, our users are consistently running more and more vm's," says The Fat Bloke. "Some of our users have large libraries of vm's of various vintages, whilst others have groups of vm's that are run together as an assembly of the various tiers in a multi-tiered software solution, for example, a database tier, middleware tier, and front-ends." The new VirtualBox release, a year in the making, addresses the needs of these users, he explains. Configuring Oracle Business Intelligence 11g MDS XML Source Control Management with Git Version Control | Christian Screen Oracle ACE Christian Screen developed this tutorial for those interested in learning how to configure the Oracle Business Intelligence 11g (11.1.1.6) metadata repository for development using the new MDS XML source control management functionality. Identity and Access Management at Oracle Open World 2012 | Brian Eidelman Fusion Middleware A-Team blogger Brian Eideleman highlights three Oracle Openworld sessions that will put Identity and Access Management in the spotlight, and shares a link to the "Focus On: Identity Management" document, a comprehensive listing of Openworld activities also dealing with IM. Starting and stopping WebLogic automatically using Upstart | Chris Johnson "In Ubuntu, RedHat and Oracle Linux there's a new flavor of init called Upstart that all the kids are using," says Oracle Fusion Middleware A-Team member Chris Johnson. "It's the new hotness when it comes to making programs into daemons and wiring them to start and stop at appropriate times." Thought for the Day "The purpose of software engineering is to control complexity, not to create it." — Pamela Zave Source: SoftwareQuotes.com

  • 2D Tile Based Collision Detection

    - by MrPlosion1243
    There are a lot of topics about this and it seems each one addresses a different problem, this topic does the same. I was looking into tile collision detection and found this where David Gouveia explains a great way to get around the person's problem by separating the two axis. So I implemented the solution and it all worked perfectly from all the testes I through at it. Then I implemented more advanced platforming physics and the collision detection broke down. Unfortunately I have not been able to get it to work again which is where you guys come in :)! I will present the code first: public void Update(GameTime gameTime) { if(Input.GetKeyDown(Keys.A)) { velocity.X -= moveAcceleration; } else if(Input.GetKeyDown(Keys.D)) { velocity.X += moveAcceleration; } if(Input.GetKeyDown(Keys.Space)) { if((onGround && isPressable) || (!onGround && airTime <= maxAirTime && isPressable)) { onGround = false; airTime += (float)gameTime.ElapsedGameTime.TotalSeconds; velocity.Y = initialJumpVelocity * (1.0f - (float)Math.Pow(airTime / maxAirTime, Math.PI)); } } else if(Input.GetKeyReleased(Keys.Space)) { isPressable = false; } if(onGround) { velocity.X *= groundDrag; velocity.Y = 0.0f; } else { velocity.X *= airDrag; velocity.Y += gravityAcceleration; } velocity.Y = MathHelper.Clamp(velocity.Y, -maxFallSpeed, maxFallSpeed); velocity.X = MathHelper.Clamp(velocity.X, -maxMoveSpeed, maxMoveSpeed); position += velocity * (float)gameTime.ElapsedGameTime.TotalSeconds; position = new Vector2((float)Math.Round(position.X), (float)Math.Round(position.Y)); if(Math.Round(velocity.X) != 0.0f) { HandleCollisions2(Direction.Horizontal); } if(Math.Round(velocity.Y) != 0.0f) { HandleCollisions2(Direction.Vertical); } } private void HandleCollisions2(Direction direction) { int topTile = (int)Math.Floor((float)Bounds.Top / Tile.PixelTileSize); int bottomTile = (int)Math.Ceiling((float)Bounds.Bottom / Tile.PixelTileSize) - 1; int leftTile = (int)Math.Floor((float)Bounds.Left / Tile.PixelTileSize); int rightTile = (int)Math.Ceiling((float)Bounds.Right / Tile.PixelTileSize) - 1; for(int x = leftTile; x <= rightTile; x++) { for(int y = topTile; y <= bottomTile; y++) { Rectangle tileBounds = new Rectangle(x * Tile.PixelTileSize, y * Tile.PixelTileSize, Tile.PixelTileSize, Tile.PixelTileSize); Vector2 depth; if(Tile.IsSolid(x, y) && Intersects(tileBounds, direction, out depth)) { if(direction == Direction.Horizontal) { position.X += depth.X; } else { onGround = true; isPressable = true; airTime = 0.0f; position.Y += depth.Y; } } } } } From the code you can see when velocity.X is not equal to zero the HandleCollisions() Method is called along the horizontal axis and likewise for the vertical axis. When velocity.X is not equal to zero and velocity.Y is equal to zero it works fine. When velocity.Y is not equal to zero and velocity.X is equal to zero everything also works fine. However when both axis are not equal to zero that's when it doesn't work and I don't know why. I basically teleport to the left side of a tile when both axis are not equal to zero and there is a air block next to me. Hopefully someone can see the problem with this because I sure don't as far as I'm aware nothing has even changed from what I'm doing to what the linked post's solution is doing. Thanks.

  • Production Access Denied! Who caused this rule anyways?

    - by Matt Watson
    One of the biggest challenges for most developers is getting access to production servers. In smaller dev teams of less than about 5 people everyone usually has access. Then you hire developer #6, he messes something up in production... and now nobody has access. That is how it always starts in small dev teams. I think just about every rule of life there is gets created this way. One person messes it up for the rest of us. Rules are then put in place to try and prevent it from happening again.Breaking the rules is in our nature. In this example it is for good cause and a necessity to support our applications and troubleshoot problems as they arise. So how do developers typically break the rules? Some create their own method to collect log files off servers so they can see them. Expensive log management programs can collect log files, but log files alone are not enough. Centralizing where important errors are logged to is common. Some lucky developers are given production server access by the IT operations team out of necessity. Wait. That's not fair to all developers and knowingly breaks the company rule!  When customers complain or the system is down, the rules go out the window. Commonly lead developers get production access because they are ultimately responsible for supporting the application and may be the only person who knows how to fix it. The problem with only giving lead developers production access is it doesn't scale from a support standpoint. Those key employees become the go to people to help solve application problems, but they also become a bottleneck. They end up spending up to half of their time every day helping resolve application defects, performance problems, or whatever the fire of the day is. This actually the last thing you want your lead developers doing. They should be working on something more strategic like major enhancements to the product. Having production access can actually be a curse if you are the guy stuck hunting down log files all day. Application defects are good tasks for junior developers. They can usually handle figuring out simple application problems. But nothing is worse than being a junior developer who can't figure out those problems and the back log of them grows and grows. Some of them require production server access to verify a deployment was done correctly, verify config settings, view log files, or maybe just restart an application. Since the junior developers don't have access, they end up bugging the developers who do have access or they track down a system admin to help. It can take hours or days to see server information that would take seconds or minutes if they had access of their own. It is very frustrating to the developer trying to solve the problem, the system admin being forced to help, and most importantly your customers who are not happy about the situation. This process is terribly inefficient. Production database access is also important for solving application problems, but presents a lot of risk if developers are given access. They could see data they shouldn't.  They could write queries on accident to update data, delete data, or merely select every record from every table and bring your database to its knees. Since most of the application we create are data driven, it can be very difficult to track down application bugs without access to the production databases.Besides it being against the rule, why don't all developers have access? Most of the time it comes down to security, change of control, lack of training, and other valid reasons. Developers have been known to tinker with different settings to try and solve a problem and in the process forget what they changed and made the problem worse. So it is a double edge sword. Don't give them access and fixing bugs is more difficult, or give them access and risk having more bugs or major outages being created!Matt WatsonFounder, CEOStackifyAgile Support for Agile Developers

  • Gartner PCC: A Shovel & Some Ah-Ha's

    - by kellsey.ruppel
    When Gartner Vice President and leading analyst Whit Andrews kicked off the Gartner Portals, Content & Collaboration Summit on Monday, March 12 at the Gaylord Palms in Orlando, FL by bringing a shovel to the stage, eyebrows raised and a few thoughts went through my head. Either this guy plans to go help the construction workers outside construct that new pool at the Gaylord or he took a wrong turn and is at the wrong conference. Oh and how did he get that shovel through airport security? As Whit explained more his objective became more clear…take everything anyone has ever told you about portals and throw it out the window, as portals have evolved and times they are most certainly changing. The future Web is here, available not only on browsers but also via a broad spectrum of access points, including automobiles, consumer electronics and more and more mobile devices. Not merely prevalent, the future Web is also multimedia-driven and operates in real time, driven by mobility, social media, streaming video and other dynamic services. Applications and user experiences are in the midst of an evolution — from the early, simple mobile Web models to today’s Web 2.0 mobile apps and, ultimately, to a world of predominantly Web apps. Additionally, cloud services will forever change how portals and user experience are designed, built, delivered, sourced and managed. So what does this mean for you? Today’s organizations need software that will enable them to not just do their jobs, but to do it in a way that is familiar and easy for them.  What does this mean for IT? Use software and technology as an enabler, not as a roadblock. Overall, we had a great week in Orlando learning about how to improve the user experience, manage content explosion, launch social initiatives, transition to mobile environments and understand cloud and SaaS options.  We had some great conversations throughout the conference and at the Oracle booth. Lots of demonstrations were given of Oracle WebCenter Sites and Oracle Social Network. And as Christie mentioned earlier this week, our Vice President of Product Management and Strategy for WebCenter Loren Weinberg presented on the topic of customer engagement and talked about how organization’s relationships with their customers have fundamentally changed today and the resulting impact that has on their priorities.  Loren also talked about the importance of customer engagement, why that matters now more than ever, and what you can do to help your company or organization succeed in this new world. The question asked in every keynote and session was a simple one: What is your “ah-ha” moment? I personally had quite a few, some of which I’ve captured below. 70% of internal social initiatives eventually fail. By 2014, refusing to communicate with consumers via social media will be as harmful as ignoring emails/phone calls is today. Customer engagement = multi-channel + social & interactive + personal & relevant + optimized. If people choose to talk about your product/company/service, it's because it's remarkable. -- Seth Godin's keynote (one of the highlights of the conference!) The Web will become the primary method used for delivering content and applications to mobile devices. By 2015, 20% of smart phone users worldwide will conduct commerce using context-enriched services on a weekly basis.  86% of customers will pay more for a better customer experience. 6 P's of Quality User Experience. Product. Enabled by: People, Patterns, Process, Profit, Priorities. Did you attend the Gartner Summit? What were your ah-ha moments?

  • Clever memory usage through the years

    - by Ben Emmett
    A friend and I were recently talking about the really clever tricks people have used to get the most out of memory. I thought I’d share my favorites, and would love to hear yours too! Interleaving on drum memory Back in the ye olde days before I’d been born (we’re talking the 50s / 60s here), working memory commonly took the form of rotating magnetic drums. These would spin at a constant speed, and a fixed head would read from memory when the correct part of the drum passed it by, a bit like a primitive platter disk. Because each revolution took a few milliseconds, programmers took to manually arranging information non-sequentially on the drum, timing when an instruction or memory address would need to be accessed, then spacing information accordingly around the edge of the drum, thus reducing the access delay. Similar techniques were still used on hard disks and floppy disks into the 90s, but have become irrelevant with modern disk technologies. The Hashlife algorithm Conway’s Game of Life has attracted numerous implementations over the years, but Bill Gosper’s Hashlife algorithm is particularly impressive. Taking advantage of the repetitive nature of many cellular automata, it uses a quadtree structure to store the hashes of pieces of the overall grid. Over time there are fewer and fewer new structures which need to be evaluated, so it starts to run faster with larger grids, drastically outperforming other algorithms both in terms of speed and the size of grid which can be simulated. The actual amount of memory used is huge, but it’s used in a clever way, so makes the list . Elite’s procedural generation Ok, so this isn’t exactly a memory optimization – more a storage optimization – but it gets an honorable mention anyway. When writing Elite, David Braben and Ian Bell wanted to build a rich world which gamers could explore, but their 22K memory was something of a limitation (for comparison that’s about the size of my avatar picture at the top of this page). They procedurally generated all the characteristics of the 2048 planets in their virtual universe, including the names, which were stitched together using a lookup table of parts of names. In fact the original plans were for 2^52 planets, but it was decided that that was probably too many. Oh, and they did that all in assembly language. Other games of the time used similar techniques too – The Sentinel’s landscape generation algorithm being another example. Modern Garbage Collectors Garbage collection in managed languages like Java and .NET ensures that most of the time, developers stop needing to care about how they use and clean up memory as the garbage collector handles it automatically. Achieving this without killing performance is a near-miraculous feet of software engineering. Much like when learning chemistry, you find that every time you think you understand how the garbage collector works, it turns out to be a mere simplification; that there are yet more complexities and heuristics to help it run efficiently. Of course introducing memory problems is still possible (and there are tools like our memory profiler to help if that happens to you) but they’re much, much rarer. A cautionary note In the examples above, there were good and well understood reasons for the optimizations, but cunningly optimized code has usually had to trade away readability and maintainability to achieve its gains. Trying to optimize memory usage without being pretty confident that there’s actually a problem is doing it wrong. So what have I missed? Tell me about the ingenious (or stupid) tricks you’ve seen people use. Ben

  • JFall 2012

    - by Geertjan
    JFall 2012 was over far too soon! Seven tracks going on simultaneously in a great location, with many artifacts reminding me of JavaOne, and nice snacks and drinks afterwards. The day started, as such things always do, with a keynote. Thanks to @royvanrijn for the photo below, I didn't take any myself and without a picture this report might have been too dry: What you see above is Steve Chin riding into the keynote hall on his NightHacking bike. The keynote was interesting, I can't be too complimentary about it, since I was part of it myself. Bert Ertman introduced the day and then Steve Chin took over, together with Sharat Chander, Tom Eugelink, Timon Veenstra, and myself. We had a strict choreography for the keynote, one that would ensure a lot of variation and some unexpected surprises, such as Steve being thrown off the stage a few times by Bert because of mentioning JavaOne too many times, rather than the clearly much cooler JFall. Steve talked about JavaOne and the direction Java is headed in, Sharat talked about JavaME and embedded devices, Steve and Tom did a demo involving JavaFX, I did a Project Easel demo, and Timon from Ordina talked about his Duke's Choice Award winning AgroSense project. I think the Project Easel demo (which I repeated later in a screencast for Parleys arranged by Eugene Boogaart) came across well and several people I spoke to especially like the roundtrip/bi-directional work that can be done, from browser to IDE and back again, very simply and intuitively. (In a long conversation on the drive back home afterwards, the scenario of a designer laying out the UI in HTML and then handing the HTML to a developer for back-end work, a developer who would then find it convenient to open the HTML in a browser and quickly navigate from the browser to the resources within the IDE, was discussed and considered to be extremely interesting and worth considering adopting NetBeans for, for no other reason than that.) Later I attended a session by David Delabassee on Java EE 7, Hans Dockter on Gradle, and Sander Mak on cross-build injection attacks. I was sorry to have missed Martijn Verburg's session, which sounded like it was really fantastic, among others, such as Gerrit Grunwald. I did a session too, entitled "Unlocking the Java EE 6 Platform", which was very well attended, pretty much a full room, and the demo went very smoothly. I talked to many people, e.g., a long time with Hans Dockter about how cool Gradle is and how great the Gradle/NetBeans plugin is turning out to be. I also had a long conversation (and did a demo) with Chris Chedgey, from Structure101, after his session, which was incredibly well attended; very interesting how popular modularity is. I met several people for the first time, as well as some colleagues from past places I've worked at. All in all, it was a great conference, unfortunately too short, which was very well attended (clearly over 1000) people, with several international speakers, as well as international attendees such as Mattias Karlsson, Sweden JUG leader. And, unsurprisingly, I came across NetBeans Platform applications again, none of which I had ever heard of before. In each case, "our fat client application" was mentioned in passing, never as a main application, and never in a context where there are plans for the application to be migrated to the web or mobile, simply because doing so makes no business sense at all. Great times at JFall, looking forward to meeting with some of the people I met again soon.
