  • Objective C and C++ for Game Development

    - by Holland
    I'm trying to figure out which language I should begin learning. I've only been programming for about 6 months, with languages like PHP, Java, and C#. I want to learn how to dev games, and while I know in most cases the answer to this would be through C++ (at least, I would think), though I'm still curious about what Objective C can offer in the sense of long term benefit. It seems like there's a chance that Objective-C may actually become more popular than C++ in a few years, and for all I know, it may become the de facto standard development language for games. Still, despite all of this, I really don't know anything, and this is all speculation. Both languages seem very interesting, and obviously can pull a lot of out of themselves. What do you think? Note: despite what some might say, I really don't want to end up using prebuilt engines, and would rather just learn how to make my own. I'm well aware that it takes a lot more time, but I'm quite ok with that.

  • MODx character encoding

    - by Piet
    Ahhh character encodings. Don’t you just love them? Having character issues in MODx? Then probably the MODx manager character encoding, the character encoding of the site itself, your database’s character encoding, or the encoding MODx/php uses to talk to MySQL isn’t correct. The Website Encoding Your MODx site’s character encoding can be configured in the manager under Tools/Configuration/Site/Character encoding. This is the encoding your website’s visitors will get. The Manager’s Encoding The manager’s encoding can be changed by setting $modx_manager_charset at manager/includes/lang/<language>.inc.php like this (for example): $modx_manager_charset = 'iso-8859-1'; To find out what language you’re using (and thus was file you need to change), check Tools/Configuration/Site/Language (1 line above the character encoding setting). This needs to be the same encoding as your site. You can’t have your manager in utf8 and your site in iso-8859-1. Your Database’s Encoding The charset MODx/php uses to talk to your database can be set by changing $database_connection_charset in manager/includes/config.inc.php. This needs to be the same as your database’s charset. Make sure you use the correct corresponding charset, for iso-8859-1 you need to use ‘latin1′. Utf8 is just utf8. Example: $database_connection_charset = 'latin1'; Now, if you check Reports/System info, the ‘Database Charset’ might say something else. This is because the mysql variable ‘character_set_database’ is displayed here, which contains the character set used by the default database and not the one for the current database/connection. However, if you’d change this to display ‘character_set_connection’, it could still say something else because the ’set character set’ statement used by MODx doesn’t change this value either. The ’set names’ statement does, but since it turns out my MODx install works now as expected I’ll just leave it at this before I get a headache. If I saved you a potential headache or you think I’m totally wrong or overlooked something, let me know in the comments. btw: I want to be able to use a real editor with MODx. Somehow.

  • SQLAuthority News – Meeting with Allen Bailochan Tuladhar – An Unlimited Experience

    - by pinaldave
    Allen  Tuladhar I recently came back from my 9-day trip in Nepal and I must say that this is one of the best trips I had in my lifetime. Allen Bailochan Tuladhar is a wonderful person and an extreme enthusiast for Microsoft Technology. Allen is the Chief Executive Officer of Unlimited Technologies Pvt Ltd., Country Manager of Microsoft MDP Nepal, the Member Secretary of Nepali Language in Information Technology, and member of the Steering Committee of the Government of Nepal. He is the person who keeps the Nepal’s Tech Community constantly motivating and taking it to the next level. I have met Allen for many times before, but this was the first time I was with him in Kathmandu, Nepal. I was very impressed with the amount of the work he does in the community. During my 9 days of stay, every single day was a new lesson for me. I was amazed and overwhelmed with the many things he does every single day. Not only he does he work closely with Government of Nepal ministry, but he is also the most known person in the Student Community. His expertise in the technical subject matter is not limited to one technology; rather, I have seen him actively engaging himself in  discussions of various tech topics. Allen presending at TechMela Kathmandu, Nepal Allen is currently active in working out to localize Windows and Office and incorporate it using the Nepali language. I was able to witness and experience how the localization works, as well as the procedure on how to do such. If you know the whole localization process, you must have realized how big and daunting of a process it is. I was glad that I became a part of it. Prominent Personality of Nepal on Panel Discussion Another great opportunity I had when I was at Allen’s office is that I have learned how the radio technology talk show works. Nepali Radio station has the weekly program in their local language, in which MS technology is discussed and industry leaders are invited to talk about their experience with the technology. I found the program so interesting because it has so much variety in terms of technology subjects. Well, my understanding of Nepali language is limited but I did understand quite a bit. Ravi, Nutan, Pinal, Gandip I got the chance to meet lots of Database Professionals as well. People in Nepal are very polite even though they are very strong in their technology fundamentals. I had in-depth discussion regarding High Availability scenarios, as well Query Tuning. Database professionals from the leading financial sectors of Nepal wanted me to visit their Data Center and help them out with a few advances. In no time, Allen organized a visit for me. He sent me a Nepali-speaking expert from his own organization to accompany me in overcoming any difficulties while I was on my way helping this financial district. Pinal (SQLAuthority) and Deependra (Unlimited) When I was going to Nepal, I was really not sure if I would be able to stay busy for 9 days straight in Community-related activity. However, on the 9th day I realize that I can still stay here for more than 9 days because in every single day, I feel enthusiastic enough to do something new. Allen Bailochan Tuladhar Even though I was working  very hard every day, I hardly had the chance to work with and talk to him one-on-one for the first few days. One of the evenings, Allen invited me to his home and we discussed about his future ideas. I was really surprised to see how much a man can do for his technical community and for his country. When I asked Allen’s wife and daughter if they ever think it’s getting too much with regards to Allen putting tough efforts to the community, their answer was something I did not expect. I found out that Allen’s wife manages all the back office and logistics of the community events and his daughter manages the websites. I felt that they do not have any complain,  and instead, their whole family is in this activity as deeply as it can get, which I thought is a very good thing. Pinal and Allen I want to end this post with an interesting story that happened during our lunch hour at one of the Nepali restaurants. While we were having our lunch and having some chitchat, Allen suddenly stood up and called several people walking along the pavement. He introduced them all to me as Microsoft Student Partners. He asked all of them to order their favorite dish and called the waiter to inform that he will pick up their tab. Figuring out the question written on my face, he just said one sentence: “They are all future technology professionals who are going to make all of us proud.” I guess I have a lot of things to learn. Hats off to Allen!

  • Hyperlinked, externalized source code documentation

    - by Dave Jarvis
    Why do we still embed natural language descriptions of source code (i.e., the reason why a line of code was written) within the source code, rather than as a separate document? Given the expansive real-estate afforded to modern development environments (high-resolution monitors, dual-monitors, etc.), an IDE could provide semi-lock-step panels wherein source code is visually separated from -- but intrinsically linked to -- its corresponding comments. For example, developers could write source code comments in a hyper-linked markup language (linking to additional software requirements), which would simultaneously prevent documentation from cluttering the source code. What shortcomings would inhibit such a software development mechanism? A mock-up to help clarify the question: When the cursor is at a particular line in the source code (shown with a blue background, above), the documentation that corresponds to the line at the cursor is highlighted (i.e., distinguished from the other details). As noted in the question, the documentation would stay in lock-step with the source code as the cursor jumps through the source code. A hot-key could switch between "documentation mode" and "development mode". Potential advantages include: More source code and more documentation on the screen(s) at once Ability to edit documentation independently of source code (regardless of language?) Write documentation and source code in parallel without merge conflicts Real-time hyperlinked documentation with superior text formatting Quasi-real-time machine translation into different natural languages Every line of code can be clearly linked to a task, business requirement, etc. Documentation could automatically timestamp when each line of code was written (metrics) Dynamic inclusion of architecture diagrams, images to explain relations, etc. Single-source documentation (e.g., tag code snippets for user manual inclusion). Note: The documentation window can be collapsed Workflow for viewing or comparing source files would not be affected How the implementation happens is a detail; the documentation could be: kept at the end of the source file; split into two files by convention (filename.c, filename.c.doc); or fully database-driven By hyperlinked documentation, I mean linking to external sources (such as StackOverflow or Wikipedia) and internal documents (i.e., a wiki on a subdomain that could cross-reference business requirements documentation) and other source files (similar to JavaDocs). Related thread: What's with the aversion to documentation in the industry?

  • Would you recommend Head First Programming for someone new?

    - by Sergio
    My brother is just starting out college. He's studying the same thing I am here in Bolivia; Systems Engineer which is the equivalent of what a CS degree is in the US. Being his big brother and a programmer myself I really want to guide him and give him the right material to learn and become good at programming. My motives are selfish I admit, I want him to become really good so he can teach me things in the future. :) After poking around the web, I found Head First Programming. This book seems to teach the fundamentals of programming, using Python as the language. Would you recommend this book as his first book ever? Would learning Python as his first language stunt him somehow? What are your thoughts and suggestions? Thanks!

  • How can a web developer contribute to Ubuntu?

    - by Kyle Macey
    I've done web development for the past ten years, and have used Ubuntu for my operating system for the past five. I feel like my design and development skills could be useful, but don't know how I can help with experience in web development. I'm currently versed in Ruby, PHP, ColdFusion, and Javascript, and I took a Java class in college. I'm also willing to learn a new language, but don't even know where to start as far as what would be most helpful to the Ubuntu community. Are there projects that a web developer could help with in Ubuntu? Or what language should I learn to best help contribute?

  • Suggestions on switching from lamp based web design-development to game design-development

    - by Sandeepan Nath
    I have around 2.5 years of experience as a web developer cum designer working mainly on the LAMP platform. Now, I want to try out game development (of the likes of First Person Shooter games like Call of Duty (COD)). It is one of my dreams to some day succeed in making a profitable, popular, commercial game of this type. However, I have never done any kind of business nor even freelancing yet even in the web domain. Okay, first things first, I am just starting and I don't yet have any idea about the technologies, languages, engines (game engines) etc involved in that. I would like this question to be a complete guide for people with similar interests. Best resources for getting hold really fast What would be the best approach to get the basic hold of the domain really fast? Any resource(s) for programmers coming from other domains/experienced in other domains would be the ideal ones for me. E.g., if anybody would ask me some good resource for quickly learning PHP/Mysql, I would suggest books like "How to do everything with PHP & MySql" - because - it introduces all the basics of the domain (not the advanced things which can be later learnt by practice and also a lot by searching in stackoverflow questions) it contains some very nice working projects in the end, which help in applying the skills learnt in the chapters of the book. This is the best way for self learners, I feel. I would appreciate some similar resource which connects all concepts together to get the bigger picture. I have read about C, C++, C#, JAVA being used in game programming but not sure which language to go for (I have previously learnt a little of C and JAVA). I have also read about game engines but there would be various other concepts. Commonly accepted ways of learning Should 3D games like these be tried after 2D games? Are there some commonly accepted ways of learning such kind of games? Like in web development, we should go for frameworks after practising well with basic language, AJAX after getting properly done with simple page-reload processing etc. Apart from these, any useful tips (like language choices etc.) would be much appreciated. Like it is highly recommended to contribute to open source web projects for getting recognition, are there similar open source game projects? Thanks, Sandeepan

  • Analyze your IIS Log Files - Favorite Log Parser Queries

    The other day I was asked if I knew about a tool that would allow users to easily analyze the IIS Log Files, to process and look for specific data that could easily be automated. My recommendation was that if they were comfortable with using a SQL-like language that they should use Log Parser. Log Parser is a very powerful tool that provides a generic SQL-like language on top of many types of data like IIS Logs, Event Viewer entries, XML files, CSV files, File System and others; and it allows you...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

  • If you had to reinvent a new syntax for regular expressions, what would it look like?

    - by Timwi
    Regular expressions as they are today are pretty much as concise and compact as they can be. Consequently, they are often criticised for being unreadable and hard to debug. If you had to reinvent a new syntax for regular expressions, what would it look like? Do you prefer the concise syntax they already have (or a different but similarly concise syntax)? If so, please justify why you think regular expressions deserve to be this concise, but your favourite programming language doesn’t (unless it’s Perl). Or do you think regular expressions should have a slightly more spaced-out syntax and look a bit more like operators and syntax elements normally do in programming languages? If so, provide examples of what you think the syntax should look like, and justify why it is better than the current syntax. Or do you think there shouldn’t even be a special syntax for regular expressions, and instead they should be constructed from syntax elements already present in the programming language? If so, give examples of a syntax that might be used to construct such regular expressions.

  • What Functional features are worth a little OOP confusion for the benefits they bring?

    - by bonomo
    After learning functional programming in Haskell and F#, the OOP paradigm seems ass-backwards with classes, interfaces, objects. Which aspects of FP can I bring to work that my co-workers can understand? Are any FP styles worth talking to my boss about retraining my team so that we can use them? Possible aspects of FP: Immutability Partial Application and Currying First Class Functions (function pointers / Functional Objects / Strategy Pattern) Lazy Evaluation (and Monads) Pure Functions (no side effects) Expressions (vs. Statements - each line of code produces a value instead of, or in addition to causing side effects) Recursion Pattern Matching Is it a free-for-all where we can do whatever the programming language supports to the limit that language supports it? Or is there a better guideline?

  • SQL SERVER – Weekend Project – Visiting Friend’s Company – Koenig Solutions

    - by pinaldave
    I have decided to do some interesting experiments every weekend and share it next week as a weekend project on the blog. Many times our business lives and personal lives are very separate, however this post will talk about one instance where my two lives connect. This weekend I visited my friend’s company. My friend owns Koenig, so of course I am very interested so see that they are doing well.  I have been very impressed this year, as they have expanded into multiple cities and are offering more and more classes about Business Intelligence, Project Management, networking, and much more. Koenig Solutions originally were a company that focused on training IT professionals – from topics like databases and even English language courses.  As the company grew more popular, Koenig began their blog to keep fans updated, and gradually have added more and more courses. I am very happy for my friend’s success, but as a technology enthusiast I am also pleased with Koenig Solutions’ success.  Whenever anyone in our field improves, the field as a whole does better.  Koenig offers high quality classes on a variety of topics at a variety of levels, so anyone can benefit from browsing this blog. I am a big fan of technology (obviously), and I feel blessed to have gotten in on the “ground floor,” even though there are some people out there who think technology has advanced as far as possible – I believe they will be proven wrong.  And that is why I think companies like Koenig Solutions are so important – they are providing training and support in a quickly growing field, and providing job skills in this tough economy. I believe this particular post really highlights how I, and Koenig, feel about the IT industry.  It is quickly expanding, and job opportunities are sure to abound – but how can the average person get started in this exciting field?  This post emphasizes that knowledge is power – know what interests you in the IT field, get an education, and continue your training even after you’ve gotten your foot in the door. Koenig Solutions provides what I feel is one of the most important services in the modern world – in person training.  They obviously offer many online courses, but you can also set up physical, face-to-face training through their website.  As I mentioned before, they offer a wide variety of classes that cater to nearly every IT skill you can think of.  If you have more specific needs, they also offer one of the best English language training courses.  English is turning into the language of technology, so these courses can ensure that you are keeping up the pace. Koenig Solutions and I agree about how important training can be, and even better – they provide some of the best training around.  We share ideals and I am very happy see the success of my friend.

  • First impressions of Scala

    - by Scott Weinstein
    I have an idea that it may be possible to predict build success/failure based on commit data. Why Scala? It’s a JVM language, has lots of powerful type features, and it has a linear algebra library which I’ll need later. Project definition and build Neither maven or the scala build tool (sbt) are completely satisfactory. This maven **archetype** (what .Net folks would call a VS project template) mvn archetype:generate `-DarchetypeGroupId=org.scala-tools.archetypes `-DarchetypeArtifactId=scala-archetype-simple `-DremoteRepositories=http://scala-tools.org/repo-releases `-DgroupId=org.SW -DartifactId=BuildBreakPredictor gets you started right away with “hello world” code, unit tests demonstrating a number of different testing approaches, and even a ready made `.gitignore` file - nice! But the Scala version is behind at v2.8, and more seriously, compiling and testing was painfully slow. So much that a rapid edit – test – edit cycle was not practical. So Lab49 colleague Steve Levine tells me that I can either adjust my pom to use fsc – the fast scala compiler, or use sbt. Sbt has some nice features It’s fast – it uses fsc by default It has a continuous mode, so  `> ~test` will compile and run your unit test each time you save a file It’s can consume (and produce) Maven 2 dependencies the build definition file can be much shorter than the equivalent pom (about 1/5 the size, as repos and dependencies can be declared on a single line) And some real limitations Limited support for 3rd party integration – for instance out of the box, TeamCity doesn’t speak sbt, nor does IntelliJ IDEA Steeper learning curve for build steps outside the default Side note: If a language has a fast compiler, why keep the slow compiler around? Even worse, why make it the default? I choose sbt, for the faster development speed it offers. Syntax Scala APIs really like to use punctuation – sometimes this works well, as in the following map1 |+| map2 The `|+|` defines a merge operator which does addition on the `values` of the maps. It’s less useful here: http(baseUrl / url >- parseJson[BuildStatus] sure you can probably guess what `>-` does from the context, but how about `>~` or `>+`? Language features I’m still learning, so not much to say just yet. However case classes are quite usefull, implicits scare me, and type constructors have lots of power. Community A number of projects, such as https://github.com/scalala and https://github.com/scalaz/scalaz are split between github and google code – github for the src, and google code for the docs. Not sure I understand the motivation here.

  • Is it illegal to rewrite every line of an open source project in a slightly different way, and use it in a closed source project?

    - by optician
    There is some code which is GPL or LGPL that I am considering using for an iPhone project. If I took that code (javascript) and rewrote it in a different language for use on the iPhone would that be a legal issue? In theory the process that has happened is that I have gone through each line of the project, learnt what it is doing, and then re implemented the ideas in a new language. To me it seems this is like learning how to implement something, but then re-implementing it separate from the original licence. Therefore you have only copied the algorithm, which arguably you could have learnt from somewhere else other than the original project. Does the licence cover the specific implementation or the algorithm as well?

  • Understanding and developing web services

    - by Pankaj Upadhyay
    This question is in conjuction with How would you approach developing a Hotel Reservation System? The solution to a system with different interfaces(or clients i should say) is to go with developing a Web service and have other systems interact with it. I never had the requirement for developing a Web service so i am bit short on it. All i understand is that A web service is a system or application that performs some operations which may include modifying, sending or receiving data over a network using HTTP protocol. (Let me know if the understanding is wrong) Now, from the other question it's clearly understood that i need to develop a web service but i have no idea as to how should i go about it. My language of choice is C# and .NET Framework. Question:: How do we develop a webservice and which tools,technology and framework should i use for the same using C# language?? Question:: How can i interact with this from a desktop WPF application, Website and Mobile app

  • QotD: Peter Wayner on Programming trend No. 1

    - by $utils.escapeXML($entry.author)
    Programming trend No. 1: The JVM is not just for Java anymoreA long time ago, Sun created Java and shared the virtual machine with the world. By the time Microsoft created C#, people recognized that the VM didn't have to be limited to one language. Anything that could be transformed into the byte code could use it.Now, it seems that everyone is building their language to do just that. Leave the job of building a virtual machine to Sun/Oracle, and concentrate your efforts on the syntactic bells and structural whistles, goes the mantra today.Peter Wayner in an article on "11 programming trends to watch" at ITWorld.

  • JSR 360 and JSR 361: A Big Leap for Java ME 8

    - by terrencebarr
    It might have gone unnoticed to some, but Java ME took a big leap forward a couple of weeks ago with the filing of two new JSRs: JSR 360: “Connected Limited Device Configuration 8″ (aka CLDC 8) JSR 361: “Java ME Embedded Profile” (aka ME EP) Together, these two JSRs will significantly update, enhance, and modernize the Java ME platform, and specifically small embedded Java, with a host of new features and functionality. JSR 360 – Connected Limited Device Configuration 8 CLDC 8 is based on JSR 139 (CLDC 1.1) and updates the core Java ME VM, language support, libraries, and features to be aligned with Java SE 8. This will include: VM updated to comply with the JVM language specification version 2 Support for SE 7/8 language features like Generics, Assertions, Annotations, Try-with-Resources, and more New libraries such as Collections, NIO subset, Logging API subset A consolidated and enhanced Generic Connection Framework for multi-protocol I/O With CLDC 8, Java ME and Java SE are entering their next phase of alignment – making Java the only technology today that truly scales application development, code re-use, and tooling across the whole range of IT platforms, from small embedded to large enterprise. JSR 361 – Java ME Embedded Profile ME EP is based on JSR 228 (IMP-NG) and updates the specification in key areas to provide a powerful and flexible application environment for small embedded Java platforms, building on the features of CLDC 8:  A new, lightweight component and services model Shared libraries Multi-application concurrency, inter-application communication, and event system Application management API optionality, to address low-footprint use cases With ME EP, application developers will have a modern application environment which allows development and deployment of  modular, robust, sophisticated, and footprint-optimized solutions for a wide range of embedded use cases and devices. Summary While these JSRs are still under development, it’s clear that there are exciting new times ahead for Java ME – turning into a serious application platform while maintaining the focus on resource-constrained devices to address the expected explosion of small, smart, and connected embedded platforms. To learn more, click on the above links for JSR 360 and JSR 361. Or review the JavaOne 2012 online presentations on the topic: CON11300: Expanding the reach of the Java ME Platform CON5943: Java ME 8 Service Platform And stay tuned for more in this space!
