  • Trying to setup first DirectX project (don't understand the error) [on hold]

    - by user1157885
    I've just started learning DirectX with the book "3D Game Programming with DirectX". I just finished setting up all the paths and adding the code to the project which I think I did correctly, but I get this massive error which I don't really understand and is hard to google. Could someone tell me what it means and how to fix it? Error 1 error TRK0002: Failed to execute command: ""C:\Program Files (x86)\Microsoft DirectX SDK (June 2010)\Utilities\bin\x64\fxc.exe" /nologo /Emain /Fo "C:\Desktop\DirectX 11 Projects\box\Win32Project2\Debug\color.cso" /Od /Zi "....\Book Files\3DGameProg\DVD\Code\Chapter 6 Drawing in Direct3D\Box\FX\color.fx"".

  • How to get shared bashed history among different tabs

    - by Luca Cerone
    I used the answer in http://unix.stackexchange.com/a/1292/41729 to enable real-time shared history among separate bash terminals. As explained in the answer above, this is achieved by adding: # avoid duplicates.. export HISTCONTROL=ignoredups:erasedups # append history entries.. shopt -s histappend # After each command, save and reload history export PROMPT_COMMAND="history -a; history -c; history -r; $PROMPT_COMMAND" This works fine if the bash shells are separate (e.g. opening different bash terminals using CTRL+ALT+T. However it doesn't work if I use tabs (from an open terminal `CTRL+SHIFT+T) rather than new windows. Why this difference in behaviour? How can I share the bash history also among various tabs?

  • Has RFC2324 been implemented?

    - by anthony-arnold
    I know RFC2324 was an April Fools joke. However, it seems pretty well thought out, and after reading it I figured it wouldn't be out of the question to design an automated coffee machine that used this extension to HTTP. We programmers love to reference this RFC when arguing web standards ("418 I'm a Teapot lolz!") but the joke's kind of on us. Ubiquitous computing research assumes that network-connected coffee machines are probably going to be quite common in the future, along with Internet-connected fruit and just about everything else. Has anyone actually implemented a coffee machine that is controlled via HTCPCP? Not necessarily commercial, but hacked together in a garage, maybe? I'm not talking about just a web server that responds to HTCPCP requests; I mean a real coffee machine that actually makes coffee. I haven't seen an example of that.

  • Resources for 2D rendering using OpenGL?

    - by nightcracker
    I noticed that there is quite some difference between 3D and 2D rendering using OpenGL, the techniques are different - pixel-perfect placing is a lot more desirable, among other things. Are there any good (complete) references on using OpenGL for rendering 2D graphics? There are quite a few "tutorials" around on the net that help you open a window, set up a half-decent environment and draw a sprite, but no real good information on rotation, blending, lightning, drawing order, using the z-buffer, particles, "complex" primitives (circles, stars, cross symbols), ensuring pixel-perfect rendering, instancing and many other staple 2D effects/techniques. Any books, great blogs, anything? Any particular awesome libraries to read?

  • Oracle GoldenGate 12c - Leading Enterprise Replication

    - by Doug Reid
    Oracle GoldenGate 12c released  on October 17th and includes several new cutting edge features that firmly establishes GoldenGate's leader position in the data replication space.   In fact, this release more than doubles the performance of data delivery, supports Oracle's new multitenant database feature,  it's more secure, has more options for high availability, and has made great strides to simplify the configuration and deployment of the product.     Read through the press release if you haven't already and do not miss the quote from Cern's Eva Dafonte Perez, regarding Oracle GoldenGate 12c "….performs five times faster compared to previous GoldenGate versions and simplifies the management of a multi-tier environment" There are a variety of new and improved features in the Oracle GoldenGate 12c.  Here are the highlights: Optimized for Oracle Database 12c -  GoldenGate 12c is custom tailored to the unique capabilities of Oracle database 12c and out of the box GoldenGate 12c supports multitenant (pluggable database (PDB)) and non-consolidated deployments of Oracle Database 12c.   The naming convention used by database 12c is now in three parts (PDB-name, schema-name, and object name).  We have made changes to the GoldenGate capture process to support the new naming convention and streamlined the whole process so a single GoldenGate capture process is being used at the container level rather than at each individual PDB.  By having the capture process at the container level resource usage and the number of processes are reduced. To view a conceptual architecture diagram click here. Integrated Delivery for the Oracle Database - Leveraging a lightweight streaming API built exclusively for Oracle GoldenGate 12c, this process distributes load, auto tunes the degree of parallelism, scales better, and delivers blinding rates of changed data delivery to the Oracle database.  One of the goals for Oracle GoldenGate 12c was to reduce IT costs by simplifying the configuration and reduce the time to manage complex infrastructures.  In previous versions of Oracle GoldenGate, customers would split transaction loads by grouping tables into multiple different delivery processes (click here to view the previous method). Each delivery process executed independently and without any interaction or knowledge of other delivery processes.  This setup was complicated to configure and time consuming as the developer needed in-depth knowledge of the source and target schemas and the transaction profile. With GoldenGate 12c and Integrated Delivery we have made it easier to configure and faster to deploy.  To view a conceptual architecture diagram of integrated delivery click here Coordinated Delivery for Non-Oracle Databases - Coordinated Delivery orchestrates high-speed apply processes and simplifies the configuration of GoldenGate for non-Oracle targets. In Oracle GoldenGate 12c a single delivery process is used with multiple threads (click here) and key events, such as primary key updates, event markers, DDL, etc, are coordinated between the various threads to insure that the transactions are applied in the same sequence as they were captured, all while delivery improved performance.  Replication Between On-Premises and Cloud-Based systems. - The trend for business to utilize both on-premises and cloud-based systems is rising and businesses need to replicate data back and forth.   GoldenGate 12c can be configured in a variety of ways to provide real-time replication when unrestricted or restricted (limited ports or HTTP tunneling) networks are between on-premises and cloud-based systems.    Expanded Heterogeneity - It wouldn't be a GoldenGate release without new and improved platform support.   Release 1 includes support for MySQL 5.6 and Sybase 15.7.   Upcoming in the next release GoldenGate, support will be expanded for MS SQL Server, DB2, and Teradata. Tighter Security - Oracle GoldenGate 12c is integrated with the Oracle wallet to shield usernames and passwords using strong encryption and aliases.   Customers accustomed to using the Oracle Wallet with other Oracle products will instantly be familiar with how to use this great new feature Expanded Oracle Application and Technology Support -   GoldenGate can be used along with Oracle Coherence to enable real-time changed data feeds to the Coherence cache using Toplink and the Oracle GoldenGate JMS adapter.     Plus,  Oracle Advanced Customer Services (ACS) now offers a low downtime E-Business Suite platform and database migrations using GoldenGate as the enabling technology.  Keep tuned for more blogs on the new features and the upcoming launch webcast where we will go into these new features in more detail.   In the mean time make sure to read through our white paper "Oracle GoldenGate 12c Release 1 New Features Overview"

  • Communities - The importance of exchange and discussion

    Communication with your environment is an essential part of everyone's life. And it doesn't matter whether you are actually living in a rural area in the middle of nowhere, within the pulsating heart of a big city, or in my case on a wonderful island in the Indian Ocean. The ability to exchange your thoughts, your experience and your worries with another person helps you to get different points of view and new ideas on how to resolve an issue you might be confronted with. Benefits of community work What happens to be common sense in your daily life, also applies to your work environment. Working in IT, or ICT as it is called in Mauritius, requires a lot of reading and learning. Not only during your lectures at the university but with your colleagues in a project assignment and hopefully with 'unknown' pals in the universe of online communities. At least I can say that I learned quite a lot from other developers code, their responses in various forums, their numerous blog articles, and while attending local user group meetings. When I started to work as a professional software developer (or engineer some may say) years ago I immediately checked the existence of communities on the programming language, the database technology and other vital information on software development in general. Luckily, it wasn't too difficult to find. My employer had a subscription of the monthly magazines and newsletters of a national organisation which also run the biggest forum in that area. Getting in touch with other developers and reading their common problems but also solutions was a huge benefit to my growth. Image courtesy of Michael Kappel (CC BY-NC 2.0) Active participation and regular contribution to this community gave me some nice advantages, too. Within three years I was listed as a conference speaker at the annual developer's conference and provided several sessions on different topics during consecutive years. Back in 2004, I took over the responsibility and management of the monthly meetings of a regional user group, and organised it for more than two years. Furthermore, I was invited to the newly-founded community program of Microsoft Germany (Community Leader/Insider Program - CLIP). My website on Active FoxPro Pages was nominated in the second batch of online communities. Due to my community work and providing advice to others, I had the honour to be awarded as Microsoft Most Valuable Professional (MVP) - Visual Developer for Visual FoxPro in the years 2006 and 2007. It was a great experience to meet with other like-minded people and I'm really grateful for that. Just in case, more details are listed in my Curriculum Vitae. But this all changed when I moved to Mauritius... Cyber island Mauritius? During the first months in Mauritius I was way too busy to think about community activities at all. First of all, there was the new company that had to be set up, the new staff had to be trained and of course the communication work-flows and so on with the project managers back in Germany had to be sorted out, too. Second, I had to get a grip of my private matters like getting the basics for my new household or exploring the neighbourhood, and last but not least I needed a break from the hectic and intensive work prior to my departure. As soon as the sea literally calmed down, I started to have conversations with my colleagues about communities and user groups. Sadly, it turned out that there were none, or at least no one was aware of any at that time. Oh oh, what did I do? Anyway, having this kind of background and very positive experience with off-line and on-line activities I decided for myself that some day I'm going to found a community in Mauritius for all kind of IT/ICT-related fields. The main focus might be on software development but not on a certain technology or methodology. It was clear to me that it should be an open infrastructure and anyone is welcome to join, to experience, to share and to contribute if they would like to. That was the idea at that time... Ok, fast-forward to recent events. At the end of October 2012 I was invited to an event called Open Days organised by Microsoft Indian Ocean Islands together with other local partners and resellers. There I got in touch with local Technical Evangelist Arnaud Meslier and we had a good conversation on communities during the breaks. Eventually, I left a good impression on him, as we are having chats on Facebook or Skype irregularly. Well, seeing that my personal and professional surroundings have been settled and running smooth, having that great exchange and contact with Microsoft IOI (again), and being really eager to re-animate my intentions from 2007, I recently founded a new community: Mauritius Software Craftsmanship Community - #MSCC It took me a while to settle down with the name but it was obvious that the community should not be attached to one single technology, like ie. .NET user group, Oracle developers, or Joomla friends (these are fictitious names). There are several other reasons why I came up with 'Craftsmanship' as the core topic of this community. The expression of 'engineering' didn't feel right with the fields covered. Software development in all kind of facets is a craft, and therefore demands a lot of practice but also guidance from more experienced developers. It also includes the process of designing, modelling and drafting the ideas. Has to deal with various types of tests and test methodologies, and of course should be focused on flexible and agile ways of acting. In order to meet and to excel a customer's request for a solution. Next, I was looking for an easy way to handle the organisation of events and meeting appointments. Using all kind of social media platforms like Google+, LinkedIn, Facebook, Xing, etc. I was never really confident about their features of event handling. More by chance I stumbled upon Meetup.com and in combination with the other entities (G+ Communities, FB Pages or in Groups) I am looking forward to advertise and manage all future activities here: Mauritius Software Craftsmanship Community This is a community for those who care and are proud of what they do. For those developers, regardless how experienced they are, who want to improve and master their craft. This is a community for those who believe that being average is just not good enough. I know, there are not many 'craftsmen' yet but it's a start... Let's see how it looks like by the end of the year. There are free smartphone apps for Android and iOS from Meetup.com that allow you to keep track of meetings and to stay informed on latest updates. And last but not least, there will be a Trello workspace to collect and share ideas and provide downloads of slides, etc. Sharing is caring! As mentioned, the #MSCC is present in various social media networks in order to cover as many people as possible here in Mauritius. Following is an overview of the current networks: Twitter - Latest updates and quickies Google+ - Community channel Facebook - Community Page LinkedIn - Community Group Trello - Collaboration workspace to share and develop ideas Hopefully, this covers the majority of computer-related people in Mauritius. Please spread the word about the #MSCC between your colleagues, your friends and other interested 'geeks'. Your future looks bright Running and participating in a user group or any kind of community usually provides quite a number of advantages for anyone. On the one side it is very joyful for me to organise appointments and get in touch with people that might be interested to present a little demo of their projects or their recent problems they had to tackle down, and on the other side there are lots of companies that have various support programs or sponsorships especially tailored for user groups. At the moment, I already have a couple of gimmicks that I would like to hand out in small contests or raffles during one of the upcoming meetings, and as said, companies provide all kind of goodies, books free of charge, or sometimes even licenses for communities. Meeting other software developers or IT guys also opens up your point of view on the local market and there might be interesting projects or job offers available, too. A community like the Mauritius Software Craftsmanship Community is great for freelancers, self-employed, students and of course employees. Meetings will be organised on a regular basis, and I'm open to all kind of suggestions from you. Please leave a comment here in blog or join the conversations in the above mentioned social networks. Let's get this community up and running, my fellow Mauritians!

  • Feeling a bit... under-challenged in my university course

    - by Corey
    I'm currently a sophomore at my university, majoring in Computer Science. Obviously, there are some programming courses as part of my curriculum. However, I'm feeling very underwhelmed by its progress. I've self-taught myself a lot and like to code in my spare time as a hobby. I'm currently in Computer Science II. I never took CS 1 because it seemed rather basic -- I asked someone in the department if they would override my CS 1 requirement if I passed their final (which I did with flying colors). Anyway, the class is going by quite slowly. It seems like the rest of the class has a hard time understanding some basic concepts, which the professor needs to keep going over to help them understand. Is this normal? Looking at the class schedule, I seem to know everything except for one or two things near the very end of the semester. Is there a different perspective I can look at this through so it doesn't seem so boring?

  • How to design network protocols

    - by dandroid
    As a programmer, you work on your software design skills. You learn about things such as modularity and reusability and how you can achieve them in code. There's plenty of literature on the subject and engineers talk about it all the time. What about if you want to design network protocols? How do you judge that protocol X is badly designed while Y is well designed? (eg. in programming you are often pointed out to a well-written piece of code in order to learn from it - what is the equivalent for network protocols?) For example, suppose I want to design a P2P protocol similar to BitTorrent or I want to make a better version of the Socks protocol. How would I go about doing a good job on this? Thanks!

  • As a young student aspiring to have a career as a programmer, how should I feel about open source software?

    - by Matt
    Every once in a while on some technology websites a headline like this will pop up: http://www.osor.eu/news/nl-moving-to-open-source-would-save-government-one-to-four-billion My initial thought about government and organizations moving to open source software is that tons of programmers would lose their jobs and the industry would shrink. At the same time the proliferation and use of open source software seems to be greatly encouraged in many programming communities. Is my thinking that the full embrace of open source software everywhere will hurt the software industry a misconception? If it is not, then why do so many programmers love open source software?

  • Improving without mentor

    - by speeder
    Although I consider myself not much experienced, I keep landing in jobs as the leader somehow (in the current one I am tech director of the company, in a previous one I was the R&D head). I understand why this happen (I have a certain specific set of skills, and I use some uncommon programming languages), my issue is: I cannot find a mentor... I know there must be stuff to me learn, and I notice as I work over the years that I am slowly learning more and more, but I believe that there are some way to get better much faster than just coding... So, how I improve when there are no other person in the company to teach me, or to me read their code? (or fix their code even...) I think I am beyond books, but way below a "master" level, so I don't know where to learn more.

  • C# String.format extension method

    - by Paul Roe
    With the addtion of Extension methods to C# we've seen a lot of them crop up in our group. One debate revolves around extension methods like this one: public static class StringExt { /// <summary> /// Shortcut for string.Format. /// </summary> /// <param name="str"></param> /// <param name="args"></param> /// <returns></returns> public static string Format(this string str, params object[] args) { if (str == null) return null; return string.Format(str, args); } } Does this extension method break any programming best practices that you can name? Would you use it anyway, if not why? If I renamed the function to "F" but left the xml comments would that be epic fail or just a wonderful savings of keystrokes?

  • Save match details to SQLite or XML?

    - by trizz
    I'm making a (conceptual) system to simulate any kind of sports match (like soccer,basketball,etc) with actions (for example pass,pass,out,pass,score) so it will be like a real report. The main statistics (play time, number of actions etc.) I'm saving to a MySQL database, but the report itself, can contain more than 1000 actions per match. To avoid millions of records in my database I'm thinking of saving the detailled report in a SQLite database or a XML file. For every match played, a file will be created. When a user request the match details, I read the file for details. What is the best choice for this purpose? SQLite or XML?

  • Best practice for managing dynamic HTML modules?

    - by jt0dd
    I've been building web apps that add and remove lots of dynamic content and even structure within the page, and I'm not impressed by the method I'm using to do it. When I want to add a section or module into a position in the interface, I'm storing the html in the code, and I don't like that: if (rank == "moderator") { $("#header").append('<div class="mod_controls">' + // content, using + to implement line breaks '</div>'); } This seems like such a bad programming practice.. There must be a better way. I thought of building a function to convert a JSON structure to html, but it seems like overkill. For the functionality of the apps I'm using: Node.js JS JQuery AJAX Is there some common way to store HTML modules externally for AJAX importation?

  • How can I create a solid business case for upgrading our programmers to 256 GB SSD and 16 GB of RAM?

    - by Alex. S.
    We have an environment based on Microsoft stack (VS2010, SQL Server, etc), and I firmly believe that we could improve productivity a little bit, having more RAM and a faster secondary SSD. What data do you advice to gather so I can solidify my request in such a way the advantages can be unbiasedly demonstrated? Currently we have only 6GB of RAM and slower HD drives, and at home I have a 128 GB SSD in my desktop and 16 GB of RAM (I also think is the max amount of memory supported by our workstations, if we could go bigger then better), so I can feel the difference and it's real. I also want to add that we are in an industry with plenty of money, so the issue actually is how to get a budget approval from management and spend it wisely to increase productivity.

  • Is Java free/open source or not?

    - by user1598390
    On November 13, 2006, Sun released much of Java as free and open source software, (FOSS), under the terms of the GNU General Public License (GPL). On May 8, 2007, Sun finished the process, making all of Java's core code available under free software/open-source distribution terms, aside from a small portion of code to which Sun did not hold the copyright. OpenJDK (Open Java Development Kit) is a free and open source implementation of the Java programming language. It is the result of an effort Sun Microsystems began in 2006. The implementation is licensed under the GNU General Public License (GNU GPL) with a linking exception. Why there are still people that say Java is not open source or free as in free speech ? Am I missing something? Is Java still privative ?

  • Opensource showcase for MVC in Java Swing

    - by Regular John
    I've allready created small desktop CRUD applications using Java/Swing. In hindsight I'm not quite sure if the overall design of these applications is good. I've also done some reading on MVC and looked at different Swing-tutorials. My problem is, that I've got a very theroatical knowledge of MVC and on the other hand, most Swing-resources don't implement the MVC-pattern. Now I would like to get my hands dirty and see how MVC is implemented in Swing in a real-world-application. Are there any opensource project you could recommend? It would be also interesting to have more than one project, to see different approaches. Best fit would be a software, that uses a relational database in the backend, to see an overall design, that I can compare to my former applications.

  • Taking Object Oriented development to the next level

    - by Songo
    Can you mention some advanced OO topics or concepts that one should be aware of? I have been a developer for 2 years now and currently aiming for a certain company that requires a web developer with a minimum experience of 3 years. I imagine the interview will have the basic object oriented topics like (Abstraction, Polymorphism, Inheritance, Design patterns, UML, Databases and ORMs, SOLID principles, DRY principle, ...etc) I have these topics covered, but what I'm looking forward to is bringing up topics such as Efferent Coupling, Afferent Coupling, Instability, The law of Demeter, ...etc. Till few days ago I never knew such concepts existed (maybe because I'm a communication engineer basically not a CS graduate.) Can you please recommend some more advanced topics concerning object oriented programming?

  • Structure gameobjects and call events

    - by waco001
    I'm working on a 2D tile based game in which the player interacts with other game objects (chests, AI, Doors, Houses etc...). The entire map will be stored in a file which I can read. When loading the tilemap, it will find any tile with the ID that represents a gameobject and store it in a hashmap (right data structure I think?). private static HashMap<Integer, Class<GameObject>> gameObjects = new HashMap<Integer, Class<GameObject>>(); How exactly would I go about calling, and checking for events? I figure that I would just call the update, render and input methods of each gameobject using the hashmap. Should I got towards a Minecraft/Bukkit approach (sorry only example I can think of), where the user registers an event, and it gets called whenever that event happens, and where should I go as in resources to learn about that type of programming, (Java, LWJGL). Or should I just loop through the entire hashmap looking for an event that fits? Thanks waco

  • How much to charge Ruby on Rails Website [closed]

    - by eWizardII
    I figured it be appropriate to ask this question on webmasters, over the stackoverflow site seeing as there are similar questions here. I am freelancing for a client in the Boston area, who has the html/css templates for their site made by another web designer. They are basically looking for someone to set up the template, and then make the backend so that a user can purchase music on their site (they are musicians). I am wondering then what would be an appropriate amount to charge them to develop such a system, I am a student, and this would be my 3rd Ruby on Rails project, but probably at least the 20 web design project I have been hired to do and I have other programming knowledge, Python, C, etc. I am thinking of suggesting that they pay 1000usd to set up such a system, but I don't know if this is appropriate. To me it seems justifiable given my experience, and the low end of RoR developers I have seen charging 25usd/hr all the way up to 150usd/hr. Any advice would be appreciated.
