  • Best design for a memory resident tool

    - by Andrew S.
    I apologize if this tends more toward design that programming, but here goes. What design would you recommend for a database that is Memory resident Must run on windows, linux and (at a stretch) the mac Accept multiple queries simultaneously Have minimum overhead, since a search is expected to take <0.25s This program implements a domain-specific search. Think of it as a database, but one that takes advantage of domain specific information to outperform a convential database search (for example, with custom oracle indexing). We have a custom data structure for our data. Our protoype is a simple exe that constructs the database in memory each time it is run. We were thinking that perhaps this program would suffice, but augmented with sockets so it can listen for queries. This database will be static. Its contents will change infrequently. We expect queries, and the solution, to be delivered via a web service.

  • Understanding the Java Ecosystem

    - by syrion
    I have traditionally had the "luxury" of being a one-man development team. I've used Python extensively, have a reasonable command of Perl, PHP, and JavaScript. My problem is Java. I can write Java code. I'm not great at it--unlike Python, I rarely make use of anything unique to Java when I'm writing it. Furthermore, my experience is mostly in simple GUI/console programming. Unfortunately, I'm currently pursuing an IT degree where Java is the lingua franca. My database class is requiring that our projects be written in Java using servlets, and I just can't wrap my head around the ecosystem. Is there a good online overview of or tutorial on how the Java web ecosystem works? I have Thinking in Java, but it's mostly just the language itself (which I understand well enough to get by). I have looked at the Sun servlet tutorial, but it seems outdated.

  • Expressing the UI for Enterprise Applications with JavaFX 2.0 FXML - Part Two

    - by Janice J. Heiss
    A new article by Oracle’s Java Champion Jim Weaver, titled “Expressing the UI for Enterprise Applications with JavaFX 2.0 FXML -- Part Two,” now up on otn/java, shows developers how to leverage the power of the FX Markup Language to define the UI for enterprise applications. Weaver, the author of Pro JavaFX Platform, extends the SearchDemoFXML example used in Part One to include more concepts and techniques for creating an enterprise application using FXML. Weaver concludes the article by summarizing its content, “FXML provides the ability to radically change the UI without modifying the controller. This task can be accomplished by loading different FXML documents, leveraging JavaFX cascading style sheets, and creating localized resource bundles. Named parameters can be used with these features to provide relevant information to an application at startup.” Check out the article here.

  • SQLBeat Podcast Episode 3 – Buck Woody – Former Nun and Windows Azooray Solutioner

    - by SQLBeat
    So here it is after so many anticpated months, Episode 3. I almost feel like like having an Amercian-style hot dog in a jar to celebrate. Buck Woody and I talk about that. And we talk about moms and a Woody tattoo,  Jehova’s Witness insurance salesmen, the proper pronunciation of Azure and character. We are in England, a country with so many names and very few ice cold beverages.  We find ourselves and our wives and yungins (we can say that cause we are from Florida) in the first SQL Saturday in the U.K., Cambridge.  Though I have spent some time with Buck over the years, this trip stood out as being one where we really bonded. And I have the audio and pictures to prove it. So without further annoying text intro, I give you 30 minutes of Buck Woody…and me asking dumb questions and saying "When I was grown up."  Enjoy.

  • Best resources to learn Game Development from a Java background?

    - by Julio
    I'm an enterprise Java programmer, however something I've been interested in and what got me into the whole programming thing was the idea of being able to create a game. Just wondering if anybody could offer any advice, or book recommendations. The side I am most interested in is game engine design and implementation. People may say "ahh but plenty exist why write your own" - its purely for learning purposes, seeing how things work and so on. So far I've taken a look at LWJGL, but achieved nothing too serious. Thanks.

  • Unity Occlusion Portals: What and How?

    - by Nick Wiggill
    (Here I eat my words on Meta about posting Unity questions on Unity Answers... since that site is less responsive than this one.) Unity provides cell-based Occlusion Culling (via Umbra, I believe). However, a newer feature that it supports is Occlusion Portals. The question is, if BSP-based occlusion culling is already a feature of Unity, what do portals add, and how? PS. This question is not "What are portals?" -- I'm aware of the original Quake BSP-style portals -- which is partly why I find the explicit portal concept in Unity odd, since it uses BSP anyway.

  • How to Build Your Own Siri App In a Browser

    - by ultan o'broin
    This post from Applications User Experience team co-worker Mark Vilrokx (@mvilrokx) about building your own Siri-style voice app in a browser using Rails, Chrome, and WolframAlpha is so just good you've now got it thrice! I love these kind of How To posts. They not only show off innovation but inspire others to try it out too. Love the sharing of the code snippets too. Hat tip to Jake at the AppsLab (and now on board with the Applications UX team too) for picking up the original All Things Rails blog post. Oracle Voice & Nuance demo on the Oracle Applications User Experience Usable Apps YouTube Channel Mark recently presented on Oracle Voice at the Oracle Usability Advisory Board on Oracle Voice and Oracle Fusion Applications and opened customers and partners eyes to how this technology can work for their users in the workplace and what's coming down the line! Great job, Mark.

    - by Anthony
    I am currently trying to install lua on my Ubuntu 12.04 on Chrome book and I keep getting this error: I'm doing good learning different programming languages (self taught) and well I wanted to start learning Lua. That error is keeping me from doing that unfortunately. I've tried doing it with and without of root access and still no success. Does anyone know what might be causing the problem or of a different way of installing Lua? Thanks a ton! Don't mind the top of the image just me taking out my frustration.

  • Established coding standards for pl/pgsql code

    - by jb01
    I need to standardize coding practises for project that compromises, among others has pl/pgsql database, that has some amount of nontrivial code. I look for: Code formatting guidelines, especially inside procedures. Guidelines on what constructs are consigered unsafe (if any) Naming coventions. Code documentation conventions (if this is pracicised) Any hints to documets that define good practises in pl/pgsql code? If not i'm looking for hints to practices that you consider good. There is related question regarding TSQL: Can anyone recommend coding standards for TSQL?, which is relevant to psql as well, but I need more information on stored procedures.

  • How do I start correctly in building database classes in c#?

    - by e4rthdog
    I am new in C# programming and in OOP. I need to dive into web applications for my company, and I need to do it fast and correct. So even that I know ASP.NET MVC is the way to go, I want to start with some simple applications with ASP.NET Webforms and then advance to MVC logic. Also regarding my db classes: I plan to create common database classes in order to be able to use them either from WinForms or ASP.NET applications. I also know that the way to go is to learn about ORM and EF. BUT I also want to start from where I am feeling comfortable and that is the traditional ADO.NET way. So about my Data Access Layer classes: Should I return my results in datasets or arraylists/lists? Should my methods do their own connect/disconnect from the db, or have separate methods and let the application maintain the connection?

  • The actual difference between styesheet in the header and a seperate file

    - by David Knight
    Am wondering if someone can give me an opinion on this. I have always been taught to have all of the CSS in a separate file that is referenced from the head of the page. Reading this article http://www.lukew.com/ff/entry.asp?1792 the author is talking about making the Guardian website responsive. One of the things he notes they did to make the site faster and more resilient is to add the CSS inline into the header, thus reducing HTTP requests. Now this got me thinking about the right/best/fastest way of using the CSS If you have one main CSS file, its going to be called and read by the site on every page, no mater how big it is. So with that in mind, Im actually starting to think its better to just inline the whole style sheet and remove one HTTP roundtrip. I know for the purposes of neatness and being able to edit the file a seperate file is better. But which would you recommend and which do you think is faster? Thanks!

  • How do you make comp.sci students and future programmers aware of the various software licenses and the nuances of it ?

    - by Samyak Bhuta
    To be specific How would you include it as part of curriculum ? Would it be too boring to just introduce them as a pure law subject ? Are there any course structure available or can we derive one ? What are the books that could be used ? I would like to see that - after going through the course - candidate is well aware of "what software licenses are and what they are good for". Various implications of not knowing it in it's proper sense. What licenses they should use for their own code. What to consider when they are trying to use certain libraries or tools in their project and gauge risks/rewards associated with it. The idea is to let them make informed choices when they are professionals/practitioners in field of programming and not make them substitute for a lawyer or even a paralegal who is going to fight the case or draft things.

  • GLSL Shader Effects: How to do motion blur, etc?

    - by DevilWithin
    I am not sure how right it is to ask this question, but still here it goes. I have a full 2D environment, with sprites going around as landscape, characters, etc And to make it more state-of-art looking, i want to implement a motion blur effect, similar to modern FPS's (i.e. crysis) blur when moving fast the camera. In a sidescroller, the desired effect is having this slight blur appearing to give the idea of fast movement, when the camera is moving. If anyone could give me some tips on doing this, im assuming in a pixel shader, i'd be grate. Also, if anyone has other good tips on cool pixel shader effects for 2D games it would be awesome, like some stylizing post fx, such as previous Prince of Persia illustrative style. Thanks

  • Liskov substitution and abstract classes / strategy pattern

    - by Kolyunya
    I'm trying to follow LSP in practical programming. And I wonder if different constructors of subclasses violate it. It would be great to hear an explanation instead of just yes/no. Thanks much! P.S. If the answer is no, how do I make different strategies with different input without violating LSP? class IStrategy { public: virtual void use() = 0; }; class FooStrategy : public IStrategy { public: FooStrategy(A a, B b) { c = /* some operations with a, b */ } virtual void use() { std::cout << c; } private: C c; }; class BarStrategy : public IStrategy { public: BarStrategy(D d, E e) { f = /* some operations with d, e */ } virtual void use() { std::cout << f; } private: F f; };

    - by Jalpesh P. Vadgama
    We all know that jQuery is a great JavaScript framework. It’s provide lots of functionalities and most used framework in programming world. But sometimes we need a functionality that does not provided by jQuery by default. At that time we need to extend jQuery. We can extend jQuery with jQuery.Extend  Method. You can get complete information from the following link. http://api.jquery.com/jQuery.extend/ It merges the contents of two or more objects together into the first object.

  • How to explain OOP concepts to a non technical person?

    - by John
    I often try to avoid telling people I'm a programmer because most of the time I end up explaining to them what that really means. When I tell them I'm programming in Java they often ask general questions about the language and how it differs from x and y. I'm also not good at explaining things because 1) I don't have that much experience in the field and 2) I really hate explaining things to non-technical people. They say that you truly understand things once you explain them to someone else, in this case how would you explain OOP terminology and concepts to a non technical person?

  • Develop secureness first or as a later step?

    - by MattyD
    The question Do you actively think about security when coding? asks about security mindset while programming. Obviously, a developer does need to think about security while coding — SQL injection, password security, etc. However, as far as the real, fully-formed security, especially the tricky problems that may not be immediately obvious, should I be concerned with tackling these throughout the development process, or should it be a step of its own in later development? I was listening to a podcast on Security Now and they mentioned about how a lot of the of the security problems found in Flash were because when Flash was first developed it wasn't built with security in mind (because it didn't need to) — therefore Flash has major security flaws at its core. I know that no one would want to actively disagree with "think security first" as a best practice, but many companies do not follow best practices. So, what is the correct approach to balance between needing to get the product done and developing it securely?

  • Change login screen to gnome-shell login

    - by Dr_Bunsen
    I was just goofing around in a vm to test what would happen if I purgen unity: sudo apt-get remove --purge unity* I found that I get an startup error, but when I proceed, I got this awesome login screen: It has an sexy effect and is just the gnome style my whole pc has got. So can any one please tell me how I change the default login screen program without having to bother clicking "fix this error" on every boot? Thanks in advance. [edit] This is the error I get, and the only option that works is the, run in low settings for one session.

  • .NET Libraries Cost More Than Windows?

    - by Kevin Mark
    When looking into libraries to make my programming life a little bit easier I've (almost) always been disappointed by the prices offered. For instance, Actipro's WPF Studio is $650. I suppose that's worth it if you plan to make money from the use of those controls. But take a look at, say, Windows. Windows 7 Ultimate is just about $220. I consider Windows to be a far more complex and "worth-it" product/purchase than a library that runs on it. Why the significant difference in pricing? Do libraries really need to be so expensive, or do they need to charge more in order to make a decent some of money?

  • How can I refactor client side functionality to create a product line-like generic design?

    - by Nupul
    Assume the following situation similar to that of Stack Overflow: I have a system with a front-end that can perform various manipulations on the data (by sending messages to REST back-end): Posting Editing and deleting Adding labels and tags Now in the first version we created it well modularized but the need as of now for 'evolving' the system similar to Stack Overflow. My question is how best to separate the commonality and how to incorporate the variability with respect to the following: Commonality: The above 'functionalities' and sending/receiving the data from the server Look and feel (also a variability as explained below) HTTP verbs associated with the above actions Variability: The RESTful URLs where the requests are sent The text/style of the UI (the commonality is analogous to Stack Overflow - the functionality of upvotes, posting a question remains the same, but the words, the icons, the look and feel is still different across sites) I think this is entirely a client-side code organization/refactoring issue. I'm heavily using jQuery, javascript and backbone for front-end development. My question is how best should I isolate the same to be able to create multiple such aspects to the tool we are currently working on?

  • How would I get work as a PHP, MySQL Developer?

    - by Matthew
    I've been working with PHP and MySQL to create various projects that I've been interested in, I can design the user interface, and the back end programming. I've created simple social networking sites, book marking sites, and project management software. So what steps would I take to get a job? Is there a market for PHP, MySQL web developers? Is it possible to take instructions and work from home for someone? How would I accept payment? Should I start a company? or work for someone? I am currently based in South Africa, many of the companies are lacking the innovation that I'm seeking for in a company.

  • Advice needed: Software Development [closed]

    - by Hunter McMillen
    I recently graduated from college with a B.S. in Computer Science, and am now currently attending the same college to get an M.S. in Computer Science. I know lots of things about Computer Science and programming but throughout all of my coursework I have never had to develop a single complete application, the projects were always relatively small (~300-500 lines of code). Basically, my overall I am about to have these two degrees and I feel like I don't know anything about software development or design; which doesn't make a whole lot of sense. I am looking for ways to fill in the gaps in my knowledge, I would love people's advice on these questions: 1) How do you design good software? Where do you start? 2) What makes a good software developer? Sorry for the convoluted question, but in my mind it is a convoluted situation. Thanks Edit Thanks everyone for your advice.

  • Making your ASP.NET/HTML Websites Indic aware &ndash; accepting Tamil, Telugu, Kannada, Hindi and ot

    - by Harish Ranganathan
    Its been a month since I wrote my last post.  Much of work has been happening around planning for Tech Ed India, the upcoming Virtual TechDays this week as well as our Developer content at the Great Indian Developer Summit 2010.  Its going to be one exciting period starting this week and I am glad I would be able to meet a lot of folks who have written to me personally that they would like to catch up at Tech Ed India. For now, I had a chance to meet the Microsoft India Development Centre team that worked on the Microsoft Indic Language Input Tool (erstwhile Akshara). The team updated me that they have also released the scripts  so that the Indic input feature can be encapsulated into your own websites.  For example, if you are having a web page where you collect user information, you can pretty much make your site indic aware i.e. accept inputs in Tamil, Telugu, Kannada, Hindi etc.,  All you would need to include would be a bunch of scripts onto your web pages and you are ready to make it, like I said, “indic aware” I have built a sample web page that accepts First Name, Last Name, Address and an additional field.  When it comes to accepting indic, sometimes, you may want to avoid the indic input in certain fields and accept it in English.  You can specify the MicrosoftILITWebAttach="false" attribute to the Text Boxes and Text Areas (TextMode=”Multiline” in ASP.NET) so that the particular field automatically switches over to English input.  Similarly, the moment you specify that the TextMode=”Password” to make it as a password field, it automatically ignores all indic recognition and shows the masked dots for the words entered. Note that, this is, when we are going for the Opt-out mode, where we are specifying that by default all the input controls would need indic awareness and we would specify for those controls where it is not required.  The other mode is Opt-in mode where you would need to add a different property to the script definition i.e. attachMode=”optin” .  When we do this, we need to explicitly add the MicrosoftILITWebAttach="true" attribute for every control where we need indic input. I have created a sample web page which accepts First Name, Last Name, Address and an additional input field to demonstrate the “Opt-out”.   You can copy paste this into any of your web pages to check it <form id="form1" runat="server">     <!-- Microsoft Indic Language Input Tool embed code --> <input type="hidden" id="MicrosoftILITWebEmbedInfo" attachMode="optout" value="" /> <script type="text/javascript" src="http://ilit.microsoft.com/bookmarklet/script/Tamil.js" defer="defer"></script>     <div>     <h2>         Welcome to the Registration Page     </h2>     <p>         First Name: <asp:TextBox runat="server" ID="txtFirstName" />         <br />         <br />         Last Name: <asp:TextBox runat="server" ID="txtLastName" />         <br />         <br />         Password:         <asp:TextBox runat="server" ID="txtPassword" TextMode="Password" />         <br />         <br />         Address: <asp:TextBox runat="server" ID="txtAddress" TextMode="MultiLine" Height="100" Width="200" />         <br />         <br />         English Text: <asp:TextBox ID="txtEnglishText" runat="server" MicrosoftILITWebAttach="false" />     </p>     <p>         <!-- Microsoft Indic Language Input Tool attribution image link --> <a style="text-decoration: none" href="http://go.microsoft.com/fwlink/?LinkID=184205&clcid=0x409"><img style="border: 0px" alt="Transliteration by Microsoft" src="http://ilit.microsoft.com/bookmarklet/images/attribution.png"></a>     </p>     </div>     </form> If you note the code snippet above, I have included the scripts in the top with the attachMode set to “optout” and for the last TextBox, I have mentioned the MicrosoftILITWebAttach="false” attribute to make it accept English input.   Additionally, you also need to add the “Microsoft Indic Language Input Tool attribution image” to your web page as a courtesy to the team that developed this feature.  It would basically add a image saying “Transliteration by Microsoft” similar to a Copy Right image.  You can see the screen shot below where I have typed it in Tamil.  In that you will notice that the password field behaves as expected and the last field accepts English Text.  You can also notice the icon that comes in the first textbox that indicates that, the field is going to accept indic text.   This sample is using Tamil, but you can pretty much do it for Hindi, Telugu, Kannada, Marathi, Bengali etc.,   The website for getting the Indic script and other instructions is http://specials.msn.co.in/ilit/WebEmbed.aspx?language=Tamil You can replace the querystring value “Tamil” to other languages as mentioned above to get the respective script. This also works for plain HTML based websites and doesn’t necessarily need you to use ASP.NET to achieve the functionality. Note that, this form is not completely localized.  This is transliterated.  You can add label controls for FirstName, LastName indication etc., and use the Visual Studio tools to localize and get those values from resource files.  In the resource files, you can enter the text in different languages to make this a truly localized page.  If you just want to download the Indic Tool Desktop version (that can be used for typing in Word, Excel, pretty much any input area), you can download it from http://specials.msn.co.in/ilit/  In the same page, there is also a web version where you can type and get text then and there if you dont want to install the desktop version. So, go ahead, download / use them in your websites and enjoy the power of Indic. Cheers !!!

  • Why is implementing copy-paste in a touch screen based smartphone such a big deal?

    - by EpsilonVector
    I'm not entirely sure this is on-topic, but it definitely needs a programmer's understanding to be answered, and deals with general development (for a specific scenario) as opposed to a specific piece of code. In a way it also translates into "what are the challenges in doing X in a touch screen app", and similar questions have been asked here in the past. So here it is: When Apple didn't implement copy-pasting on the iPhone since version 1 I just assumed it was a UI issue- they were waiting until they figured out a good UI for it. But now the idea is out there, and Microsoft still released Windows Phone 7 without copy-pasting, promising it'll be ready in a few months. My question is: why does this takes a few months to implement? Are there some technological challenges that are unique to programming for a touch screen that I'm not familiar with?

  • What are some recommended video lectures for a non-CS student to prepare for the GRE CS subject test?

    - by aristos
    Well the title kinda explains all there is to explain. I'm a non-cs student and was preparing to apply PhD programs in applied mathematics. But for my senior thesis I've been reading lots of machine learning and pattern recognition literature and enjoying it a lot. I've taken lots of courses with statistics and stochastics content, which I think, would help me if I get accepted to a program with ML focus, but there are only two CS courses -introduction to programming- in my transcript and therefore I decided to take the CS subject test to increase my chances. Which courses do you think would be most essential to have a good result from CS subject test? I'm thinking of watching video lectures of them, so do you have any recommendations?
