• Help with setting up AIM account

  - by Aaron

  Can anyone help me configure my AIM account? I have Oneiric and I want to set up my AIM account with what I believe is a chat client (the envelope icon on the top right). It is called Empathy. \n I tried to do this using Broadcast Account. It let me choose what account (Jabber, Pidgin, Aim, etc...). Once I entered my password for my AIM account, I got a pop-up asking for the master password for my Keyring. I didn't know what that was at the time so I closed that window after trying to enter my account password. Keyring apparently asks for a master password and it holds any keys you want to remember in the future. It gave me an error so I couldn't set up my AIM account completely. Now I'm trying to get back to that screen but I can only set up a Twitter or Facebook. Thanks, Aaron P.S. Can anyone tell me how to break the message up so it doesn't appear all on one line? I tried 'coding' a \n...seemed to work.

• Box2D: How to get the Exact Collision Point and ignore the collision (from 2 "ghost bodies")

  - by Moritz

  I have a very basic problem with Box2D. For a arenatype game where you can throw scriptable "missiles" at other players I decided to use Box2D for the collision detection between the players and the missiles. Players and missiles have their own circular shape with a specific size (varying). But I don´t want to use dynamic bodies because the missiles need to move themselve in any way they want to (defined in the script) and shouldnt be resolved unless the script wants it. The behavior I look for is as following (for each time step): velocity of missiles is set by the specific missile script each missile is moved according to that velocity if a collision accurs now, I want to get the exact position of impact, and now I need a mechanism to decide if the missile should just ignore the collision (for example collision between two fireballs which shouldnt interact) or take it (so they are resolved and dont overlap anymore) So is there a way in Box2D to create Ghost bodies and listen to collisions from them, then deciding if they should ignore the collision or should take them and resolve their position? I hope I was clear enough and would be happy about any help!

• C#.NET (AForge) against Java (JavaCV, JMF) for video processing

  - by Leron

  I'm starting to get really confused looking deeper and deeper at video processing world and searching for optimal choices. This is the reason to post this and some other questions to try and navigate myself in the best possible way. I really like Java, working with Java, coding with Java, at the same time C# is not that different from Java and Visual Studio is maybe the best IDE I've been working with. So even though I really want to do my projects in Java so I can get better and better Java programmer at the same time I'm really attract to video processing and even though I'm still at the beginning of this journey I want to take the right path. So I'm really in doubt could Java be used in a production environment for serious video processing software. As the title says I already have been looking at maybe the two most used technologies for video processing in Java - JMF and JavaCV and I'm starting to think that even they are used and they provide some functionality, when it comes to real work and real project that's not the first thing that comes to once mind, I mean to someone that have a professional opinion about this. On the other hand I haven't got the time to investigate .NET (c# specificly) options but even AForge looks a lot more serious library then those provided for Java. So in general -either ways I'm gonna spend a lot of time learning some technology and trying to do something that make sense with it, but my plan is at the end the thing that I'll eventually come up to be my headline project. To represent my skills and eventually help me find a job in the field. So I really don't want to spend time learning something that will give me the programming result I want but at the same time is not something that is needed in the real world development. So what is your opinion, which language, technology is better for this specific issue. Which one worths more in terms that I specified above?

• Which open source PHP project has the 'perfect' OOP design I can learn from?

  - by aditya menon

  I am a newbie to OOP, and I learn best by example. You could say this question is similar to Which Scala open source projects should I study to learn best coding practices - but in PHP. I have heard-tell that Symfony has the best 'architecture' (I will not pretend I know what that exactly means), as well as Doctrine ORM. Is it worth it to spend many months reading the source code of these projects, trying to deduce the patterns used and learning new tricks? I have seen equal number of web pages dissing and liking Zend's codebase (will provide links if deemed necessary). Do you know of any other project that would make any veteran OOP developer shed tears of joy? Please let me add that practicality and scope of use is not a concern at all here - I just want to do: Pick a project that has a codebase deemed awesome by devs way better and greater than me. Write code that achieves what the project does. Compare results and try to learn what I don't know. Basically, an academic interest codebase. Any recommendations please?

• Guide.BeginShowMessageBox wrapper

  - by Daniel Moth

  While coding for Windows Phone 7 using Silverlight, I was really disappointed with the built-in MessageBox class, so I found an alternative. My disappointment was the fact that: Display of the messagebox causes the phone to vibrate (!) Display of the messagebox causes the phone to make an annoying sound. You can only have "ok" and "cancel" buttons (no other button captions). I was using the messagebox something like this: // Produces unwanted sound and vibration. // ...plus no customization of button captions. if (MessageBox.Show("my message", "my caption", MessageBoxButton.OKCancel) == MessageBoxResult.OK) { // Do something Debug.WriteLine("OK"); } …and wanted to make minimal changes throughout my code to change it to this: // no sound or vibration // ...plus bonus of customizing button captions if (MyMessageBox.Show("my message", "my caption", "ok, got it", "that sucks") == MyMessageBoxResult.Button1) { // Do something Debug.WriteLine("OK"); } It turns out there is a much more powerful class in the XNA framework that delivered on my requirements (and offers even more features that I didn't need like choice of sounds and not blocking the caller): Guide.BeginShowMessageBox. You can use it simply by adding an assembly reference to Microsoft.Xna.Framework.GamerServices. I wrote a little wrapper for my needs and you can find it here (ready to enhance with your needs): MyMessageBox.cs.txt. Comments about this post welcome at the original blog.

• When and why you should use void (instead of i.e. bool/int)

  - by Jonas

  I occasionally run into methods where a developer chose to return something which isn't critical to the function. I mean, when looking at the code, it apparently works just as nice as a void and after a moment of thought, I ask "Why?" Does this sound familiar? Sometimes I would agree that most often it is better to return something like a bool or int, rather then just do a void. I'm not sure though, in the big picture, about the pros and cons. Depending on situation, returning an int can make the caller aware of the amount of rows or objects affected by the method (e.g., 5 records saved to MSSQL). If a method like "InsertSomething" returns a boolean, I can have the method designed to return true if success, else false. The caller can choose to act or not on that information. On the other hand, May it lead to a less clear purpose of a method call? Bad coding often forces me to double-check the method content. If it returns something, it tells you that the method is of a type you have to do something with the returned result. Another issue would be, if the method implementation is unknown to you, what did the developer decide to return that isn't function critical? Of course you can comment it. The return value has to be processed, when the processing could be ended at the closing bracket of method. What happens under the hood? Did the called method get false because of a thrown error? Or did it return false due to the evaluated result? What are your experiences with this? How would you act on this?

• Security Goes Underground

  - by BuckWoody

  You might not have heard of as many data breaches recently as in the past. As you’re probably aware, I call them out here as often as I can, especially the big ones in government and medical institutions, because I believe those can have lasting implications on a person’s life. I think that my data is personal – and I’ve seen the impact of someone having their identity stolen. It’s a brutal experience that I wouldn’t wish on anyone. So with all of that it stands to reason that I hold the data professionals to the highest standards on security. I think your first role is to ensure the data you have, number one because it can be so harmful, and number two because it isn’t yours. It belongs to the person that has that data. You might think I’m happy about that downturn in reported data losses. Well, I was, until I learned that companies have realized they suffer a lowering of their stock when they report it, but not when they don’t. So, since we all do what we are measured on, they don’t. So now, not only are they not protecting your information, they are hiding the fact that they are losing it. So take this as a personal challenge. Make sure you have a security audit on your data, and treat any breach like a personal failure. We’re the gatekeepers, so let’s keep the gates.

• Should I be using Lua for game logic on mobile devices?

  - by Rob Ashton

  As above really, I'm writing an android based game in my spare time (android because it's free and I've no real aspirations to do anything commercial). The game logic comes from a very typical component based model whereby entities exist and have components attached to them and messages are sent to and fro in order to make things happen. Obviously the layer for actually performing that is thin, and if I were to write an iPhone version of this app, I'd have to re-write the renderer and core driver (of this component based system) in Objective C. The entities are just flat files determining the names of the components to be added, and the components themselves are simple, single-purpose objects containing the logic for the entity. Now, if I write all the logic for those components in Java, then I'd have to re-write them on Objective C if I decided to do an iPhone port. As the bulk of the application logic is contained within these components, they would, in an ideal world, be written in some platform-agnostic language/script/DSL which could then just be loaded into the app on whatever platform. I've been led to believe however that this is not an ideal world though, and that Lua performance etc on mobile devices still isn't up to scratch, that the overhead is too much and that I'd run into troubles later if I went down that route? Is this actually the case? Obviously this is just a hypothetical question, I'm happy writing them all in Java as it's simple and easy get things off the ground, but say I actually enjoy making this game (unlikely, given how much I'm currently disliking having to deal with all those different mobile devices) and I wanted to make a commercially viable game - would I use Lua or would I just take the hit when it came to porting and just re-write all the code?

• Drawing particles as a smooth blob

  - by Nömmik

  I'm new to game/graphics development and I'm playing around with particles (in 2D). I want to draw particles close to each other as a blob, just as liquid/water. I do not want to draw big circles overlapping as the blob won't be smooth (and too big). I don't really know physics but I assume what I want is something looking similar to surface tension. I haven't been able to find anything on stackexchange or on Google (maybe I do not know the correct keywords?). So far I have found two possible solutions, but I am unable to find any concrete information about algorithms. One of them is to calculate the concave hull of particles I consider being a blob. I can calculate the blob by creating an equivalence class (on the relation "close to each other"). Strangely enough I haven't been able to find any algorithm explaining how to calculate the concave hull. Many posts (and among stackexchange) links to libraries or commercial products that do this (I need libraries to work in C#), but never any algorithm. Also this solution might have a problem with a circle of particles, which would not detect the empty space in the middle. While researching concave hull I stumbled upon something called alpha shapes. Which seems to be exactly what I want to do, however just as with concave hull I haven't found any source explaining how they actually work. I have found some presentation materials but not enough to go on. It's like a big secret everyone knows except me :-/ After calculating the concave hull or alpha shape I want to make it a Bézier curve to make it smooth and nice. Although I do find my approach a bit too complex, maybe I am trying to solve this the wrong way? If you can either suggest any other solution to my problem, or explain the pieces I am missing I would be very happy and grateful :-) Thanks.

• Computer Bugs - Etymology and Entomology

  - by PointsToShare

  Whatever bugs you My wife and I used to take some of our summer vacation I a cabin on the shore of Lake Atsion in NJ. I t is a delightful place in the Wharton forest with Brown yet fresh water, where we would canoe, swim and enjoy true rest. Alas, in the last few years, yellow flies also discovered the area’s pastoral delights and came in hoards to bug us. So much so that we had to give up. As a computer programmer I abhor bugs. The bugs that bug me – except the pesky yellow flies – are program bugs , a specific variety of computer bugs. You can find an excellent take on the etymology of the word ‘bug” in this delightful monogram: http://www.jamesshuggins.com/h/tek1/first_computer_bug.htm In my youth, I worked on Burroughs computers. Unlike their IBM brethren, the Burroughs used a 96 column card. The cards were much smaller than the 80 column IBM cards. We wrote our programs on coding sheets and then a key-punch operator transcribed them into punched cards. These were fed into a card reader and compiled. The compiler would notify us of compiler errors or bugs, but it was not always easy to get the meaning of the message. My friend Mark Wildt, also a Burroughs veteran, gave me an old punched card from one of his programs. Obviously a bug!! Here It Is!! That’s All Folks!

• How to organize a programming course?

  - by Bogdan Gavril

  I've been given the task to train our manual testers to become developers in test (write test automation!). some have basic programing knowledge (either dabbling in PHP or reading stuff) and some who have no experience. Note that I do have teaching experience, but with real students, not employees, and one concern is that they will not put extra hours except the 20% management gave them for the transition. Language to be taught and used: C# We have 8 hours per week to do this and should decide if they will make it in 2 months. I am thinking of a combined approach: use a manual such as Head First C# (although I'm not happy with the labs, they're mostly games and I don't want to add UI complexities) have them read from the manual do labs with them, solving more and more difficult problems and explain the theoretical stuff as well have them do a bigger project towards the end Some questions: do you have a better suggestion as far as manuals go? do you have a better aproach? Focus less on labs? what kind of assesments should I use and how often? should I let them do a bigger project (bank system or small game) and how much time should I invest in that? ideeas on labs? other resources ? Any other tips would be most welcomed! Thanks!

• Octree implementation for fustrum culling

  - by Manvis

  I'm learning modern (=3.1) OpenGL by coding a 3D turn based strategy game, using C++. The maps are composed of 100x90 3D hexagon tiles that range from 50 to 600 tris (20 different types) + any player units on those tiles. My current rendering technique involves sorting meshes by shaders they use (minimizing state changes) and then calling glDrawElementsInstanced() for drawing. Still get solid 16.6 ms/frame on my GTX 560Ti machine but the game struggles (45.45 ms/frame) on an old 8600GT card. I'm certain that using an octree and fustrum culling will help me here, but I have a few questions before I start implementing it: Is it OK for an octree node to have multiple meshes in it (e.g. can a soldier and the hex tile he's standing on end up in the same octree node)? How is one supposed to treat changes in object postion (e.g. several units are moving 3 hexes down)? I can't seem to find good a explanation on how to do it. As I've noticed, soting meshes by shaders is a really good way to save GPU. If I put node contents into, let's say, std::list and sort it before rendering, do you think I would gain any performance, or would it just create overhead on CPU's end? I know that this sounds like early optimization and implementing + testing would be the best way to find out, but perhaps someone knows from experience?

• Continual Professional Development - proving new skills to non-technical employers

  - by Tom

  Background I work in a non-IT based company, as a professional software developer, building a large scale internal database system. I am fortunate to have a fairly senior position within the company, and have been working here for around 4 years. Often I get asked by management "how do you learn new things?". To be honest, I don't know how to answer this. Over the last 6 months, I've really gotten my teeth into some new techniques and technologies to make my level of coding far better and hopefully improve the quality of the software. Even if it's just refreshing my skills on things I've learnt already. Like last week I dived into some complex XLinq and TPL code (.net). Nothing revolutionary, but I feel like I am a bit better than before. Question The question is, how do I prove this to my employer? It'd be nice to be able to put this on paper. Possibilities I could: Keep a journal of what I've learnt - keeping the technical bits in (nobody would understand or care, but it's better than them being omitted) ???? (I've run out of ideas already) Any ideas? Thanks, Tom

• How can I make video games if I don't like programming?

  - by hoper

  I am studying C++ code in my school (my major is computer programming). Honestly, my grades are not so good, and assignments are really hard. Sometimes I feel sad that I will spend 8-10 hours per day coding (which is stressful) in the future for my job. But I still want to make video games. Maybe this is the only reason why I am taking all of these stressful courses. I always write down plots, stories, characters, fictional gaming worlds... Once, I thought I should study artistic technology such as game design and not computer technology such as C++, C#, etc. However, most of popular game designers (or directors) such as Kojima, Miyamoto, etc. used to be good programmers. Companies actaully assign programmers to directors because they understand how to make a game. I've try to find other colleges or universities where they teach game design programs. However, one article that lists rank 10 game design schools in North America seems untrustful because the survey company only scores it from intervews of students. Once, I tried to attend Art Institute of Vancouver which is rank 7 according to that article. However, one programmer who used to be an instructor in there told me the truth: the employement rate of graduated students is low. How can I have a future making games if I don't like programming?

• Mac OS needs Windows Live Writer &ndash; badly!

  - by digitaldias

  I recently bought a new  Macbook Pro (the 13” one) to dive into a new world of programming challenges as well as to get a more powerful netbook than my Packard Bell Dot which I’ve been using since last year. I’ve had immense pleasure using the netbook format and their small size in meetings (taking notes with XMind), surfing “anywhere”, and, of course blogging with windows live writer. So far the Mac is holding up, it’s sleek, responsive, and I’ve even begun looking at coding in Objective C with it, but in one arena, it is severely lacking: Blogging software. There is nothing that even comes close to Live Writer for getting your blog posts out. The few blogger applications that do exist on mac both look and feel medieval in comparison, AND some even cost money! It looks like some mac users actually install a virtual machine on their mac to run Windows XP just so they can use WLW. I’m not that extreme; instead, I’m hoping that the WLW team will write it’s awesome application as a Silverlight 4 app. That way, it would run on Mac and Windows (as a desktop app). I wonder if it will ever happen though…   PS: The image is of me, took it with the built-in camera on the mac and emailed it to the windows PC that I am writing on :)

• Are there opportunities working as full-time paid programmer for Non-profit organizations

  - by Rick

  Some recent events in my life have made me want to contribute more to causes I believe in rather than just working for a profit-driven company. I have been thinking that if I could find a non-profit organization that I like and believe in then I might feel more fulfilled working for them. I have a decent amount of web development experience and currently work as a Java / Spring web developer. I realize the compensation wouldn't have the same "ceiling" potential as for-profit but am wondering if its possible to get at least something close to a market rate for work as I am planning to start a family sometime soon and still need a legitimate income. If anyone has any knowledge or experience about this sort of thing would be happy to hear from you. EDIT: Without getting in to too much personal detail, I have a relative who recently passed away who suffered from a mental illness so while it doesn't have to be an organization specifically dedicated to this, I am hoping to work for something along these lines at least where there is more of a social cause rather than just working on an open-source project whose only cause is the advancement of technology.

• Basic Connections Through Socket Server

  - by Walrus

  I'm designing a simple 2 player RTS with Stencyl, a program that uses blocks for coding. The current code updates lists whenever an actor moves (new X and Y), and I'd want the server to update the game state with each change to the list. However, to start off: I don't even know how to set up a socket server. Stencyl has taught me the basics of logic, but I've yet to learn any programming languages. I've downloaded a Smartfox 2X socket server that I'm intending to use. Right now I'm only looking to make baby steps; I want to do something to this effect: "When someone connects to the server, open insert file here". How can I do this? My intention is to have this file be the game client. Is this "open file when connected" method the best way to go about this? When answering: assume that I know nothing, because really, though I have done research (I know that UDPTCP for real time), implementation-wise I know nothing.

• Displaying the Saved Pictures in the Windows Phone 8 emulator

  - by Laurent Bugnion

  One cool feature of the Windows Phone emulator is that it allows you to select pictures from your app (using the PhotoChooserTask) without having to try your app on a physical device. For example, this code (which I used in some of my recent presentations) will trigger the Photo Chooser UI to be displayed on the emulator too: private Action<IEnumerable<IImageFileInfo>> _callback; public void SelectFiles(Action<IEnumerable<IImageFileInfo>> callback) { var task = new PhotoChooserTask { ShowCamera = true }; task.Completed += TaskCompleted; _callback = callback; task.Show(); } void TaskCompleted(object sender, PhotoResult e) { if (e.Error == null && e.ChosenPhoto != null && _callback != null) { var fileName = e.OriginalFileName .Substring(e.OriginalFileName.LastIndexOf("\\") + 1); var info = new FileViewModel(e.ChosenPhoto, fileName); var infos = new List<IImageFileInfo> { info }; _callback(infos); } } In Windows Phone 8 however, when you execute this code, you will be shown an almost empty Photo Chooser UI: Notice that the “Saved Pictures” album is missing. At first I thought it was just not there at all, but you can actually restore it with the following steps: Press on the Windows button On the main screen, press on Photos Press on Albums Open the so called “8” photo album Press Back until you are back into your app and try again. This time you will see the saved pictures, and can perform your tests in more realistic conditions! Happy coding!

• sublime text 2 review !

  - by Anirudha

  Few months ago I am looking for a editor to doing simply edit on html,css,javascript.  Before it I tried notepad++ which is quite awesome to do all works I want to get done with him.  I choose 2 editor on my list. first is sublime text and second is phpstorm. both are cross-plateform. I tried both and both is working fine. I finally go with sublime text 2.   Here is the reason why sublime text 2 is awesome. phpstorm and sublime text 2 both is licensed  software. In sublime text 2 you can use it for unlimited time when phpstorm is available for 30 days only. Sublime text 2 is very memory efficient and lightweight software this is first thing people found best in sublime text 2. in phpstorm problem for me is sometime it’s goes unresponsive when I tried html5 boilerplate. sublime text 2 is never hang depend on memory size of project compare to phpstorm. in Sublime text 2 you can got better speed at coding after learning some shortcut and basic thing applied specially sublime text 2. Sublime text 2 come with distraction free mode when phpstorm have nothing with full-screen. Sublime text 2 support almost every language. I have seen many people in community who has move from their PHP IDE to sublime text 2. You can use LESS and coffeescript in it. There are many kind of customization out in github regarding sublime text 2.   In past I also have also tried webmatrix. the latest version of webmatrix have nothing good as sublime text 2. Sublime text 2 is best fit for my requirement.   So cheers, people should tried once Sublime text 2 if they are look for a solid tool for learning new things. sublime text 2 can be downloaded from http://www.sublimetext.com/.   Thanks for reading my post.

• How to improve Algorithmic Programming Solving skill? [closed]

  - by gaurav

  Possible Duplicate: How can I improve my problem-solving ability? How do you improve your problem solving skills? Should I learn design patterns or algorithms to improve my logical thinking skills? What to do when you're faced with a problem that you can't solve quickly? Are there non-programming related activities akin to solving programming problems? I am a computer engineering graduate. I have studied programming since three years. I am good in coding and programming. I have been trying to compete in algorithmic competitions on sites such as topcoder,spoj since one and a half year, but I am still unable to solve problems other than too easy problems. I have learned from people that it takes practice to solve such problems. I try to solve those problems but sometimes I am unable to understand and even if I do understand I am unable to think of a good algorithm for solving it. Even if I solve I get Wrong answer and I am unable to figure out what is the problem with my code as it works on samples given on the sites but fails on test cases which they do not provide. I really want to solve those problems and become good in algorithms. I have read books for learning algorithms like Introduction to algorithms by CLRS,practicing programming questions. I have gone through some questions but they don't answer this question. I have seen the questions which are said duplicates but those questions focus on overall programming, but I am asking for algorithm related programming, basically for competing in programming which involve solving a problem statement then online judge will automatically evaluate it, such type of programming is quite different from the type of programming these questions discuss.

• Is it just me or is this a baffling tech interview question

  - by Matthew Patrick Cashatt

  Background I was just asked in a tech interview to write an algorithm to traverse an "object" (notice the quotes) where A is equal to B and B is equal to C and A is equal to C. That's it. That is all the information I was given. I asked the interviewer what the goal was but apparently there wasn't one, just "traverse" the "object". I don't know about anyone else, but this seems like a silly question to me. I asked again, "am I searching for a value?". Nope. Just "traverse" it. Why would I ever want to endlessly loop through this "object"?? To melt my processor maybe?? The answer according to the interviewer was that I should have written a recursive function. OK, so why not simply ask me to write a recursive function? And who would write a recursive function that never ends? My question: Is this a valid question to the rest of you and, if so, can you provide a hint as to what I might be missing? Perhaps I am thinking too hard about solving real world problems. I have been successfully coding for a long time but this tech interview process makes me feel like I don't know anything. Final Answer: CLOWN TRAVERSAL!!! (See @Matt's answer below) Thanks! Matt

• Programming and Ubiquitous Language (DDD) in a non-English domain

  - by Sandor Drieënhuizen

  I know there are some questions already here that are closely related to this subject but none of them take Ubquitous Language as the starting point so I think that justifies this question. For those who don't know: Ubiquitous Language is the concept of defining a (both spoken and written) language that is equally used across developers and domain experts to avoid inconsistencies and miscommunication due to translation problems and misunderstanding. You will see the same terminology show up in code, conversations between any team member, functional specs and whatnot. So, what I was wondering about is how to deal with Ubiquitous Language in non-English domains. Personally, I strongly favor writing programming code in English completely, including comments but ofcourse excluding constants and resources. However, in a non-English domain, I'm forced to make a decision either to: Write code reflecting the Ubiquitous Language in the natural language of the domain. Translate the Ubiquitous Language to English and stop communicating in the natural language of the domain. Define a table that defines how the Ubiquitous Language translates to English. Here are some of my thoughts based on these options: 1) I have a strong aversion against mixed-language code, that is coding using type/member/variable names etc. that are non-English. Most programming languages 'breathe' English to a large extent and most of the technical literature, design pattern names etc. are in English as well. Therefore, in most cases there's just no way of writing code entirely in a non-English language so you end up with a mixed languages. 2) This will force the domain experts to start thinking and talking in the English equivalent of the UL, something that will probably not come naturally to them and therefore hinders communication significantly. 3) In this case, the developers communicate with the domain experts in their native language while the developers communicate with each other in English and most importantly, they write code using the English translation of the UL. I'm sure I don't want to go for the first option and I think option 3 is much better than option 2. What do you think? Am I missing other options?

  - by Brian Jackett

  On March 10th, 2012 the first ever PowerShell Saturday conference took place in Columbus, OH and I couldn’t be happier with the outcome.  We had 100 attendees from 10 different states (the biggest surprise to me) come to see 6 speakers present on a variety of PowerShell topics: introduction, WMI, SharePoint, Active Directory, Exchange, 3rd party products and more.      A big thank you also goes out to a number of people. Planning committee Wes Stahler, lead organizer of PowerShell Saturday Columbus, president of Central Ohio PowerShell User Group Ed “Microsoft Scripting Guy” Wilson Teresa “The Scripting Wife” Wilson Ashley McGlone Brian T. Jackett (myself) Speakers Ed Wilson Ashley McGlone James Brundage Trevor Sullivon Daniel Cruz Volunteer Lisa Gardner, fellow Microsoft PFE volunteered her time on a Saturday to assist with smooth operation of the day Facility Coordination Debbie Carrier, facilities coordinator for the Columbus Microsoft Office and helped us out greatly with the venue   Slides and Script Samples    I presented my session on “PowerShell for the SharePoint 2010 Developer”.  Below you can download the slides and script samples.   Photos    I wasn’t able to take took many pictures (only 3) as I was busy doing my presentation, answering questions, and taking care of random items throughout the day.   Pictures on Facebook    click here Pictures on SkyDrive (higher res) PowerShell Saturday Columbus Mar '12 VIEW SLIDE SHOW DOWNLOAD ALL   Conclusion    I’m very happy that this first ever PowerShell Saturday was a success.  My fellow PFE and speaker Ashley McGlone also has a short write-up on his blog about the event (click here).  I have heard rumors that there are other cities starting to plan their own local events.  When I hear more details I’ll spread the word here and on Twitter.         -Frog Out
