  • Fundamental programming book [closed]

    - by Luke Annison
    I'm a fairly new programmer and currently learning ruby on rails with the intention of developing a web application. I am currently going reading Agile Web Development with Rails 4th Edition and its working well for me, however I'm wondering if somebody can recommend a more general, almost classic book to read casually alongside to help cement the fundamentals in place. As I said, I'm for the most part a beginner and the only education I've had is this and briefly one other technical book, so I'm sure there must be some "must reads" out there that give me a more substantial context for the basics of either Ruby on Rails, Ruby, objective oriented programming, or programming in general. What books helped you grasp a deeper and more rounded understanding of your skills as a programmer? All suggestions are welcome and appreciated.

  • Book Review: Expert Cube Development with Microsoft SQL Server 2008 Analysis Services

    - by Greg Low
    I spent last week on campus in Redmond with the SQL Server Analysis Services Maestro program. It was great to have a chance to focus on SSAS for a week. As part of that, I did quite a bit of reading as I had quite a bit of travelling time. Ironically, I re-read a few books. The first was Marco Russo, Alberto Ferrari and Chris Webb's book Expert Cube Development with Microsoft SQL Server 2008 Analysis Services . I've often told BI classes that I've been teaching that this is a really good book and...(read more)

  • Free E-Book - Testing for Continuous Delivery with Visual Studio 2012

    - by TATWORTH
    Originally posted on: http://geekswithblogs.net/TATWORTH/archive/2013/11/05/free-e-book---testing-for-continuous-delivery-with-visual-studio.aspx At http://msdn.microsoft.com/en-us/library/jj159345.aspx, Microsoft Press are offering the free e-Book, Testing for Continuous Delivery with Visual Studio 2012. "As more software projects adopt a continuous delivery cycle, testing threatens to be the bottleneck in the process. Agile development frequently revisits each part of the source code, but every change requires a re-test of the product. While the skills of the manual tester are vital, purely manual testing can't keep up. Visual Studio 2012 provides many features that remove roadblocks in the testing and debugging process and also help speed up and automate re-testing. " (Please ignore the click to look inside!)

  • Address Book Authentication

    - by Gus E
    I just upgraded to Ubuntu 14.04.1 and run Gnome Shell. I am consistently getting a pop up window prompting me for my Gmail address book authentication. The window pops up the moment I type something into gnome shell after hitting the super key. I'm assuming that Ubuntu wants to search my address book for people to include in the search. I have opened up the settings and deleted my account from the online accounts section and rebooted, nothing seems to stop the popup. Where is it getting my email address from? Most importantly, how to I stop this super annoying popup from appearing?

  • iOS Book App with Custom Book Repositories. Will Apple block this? [closed]

    - by BrianHanifin
    I am working with a kindergarten teacher to create an iPad/iPhone app which plays audio of her narrating each page of the "book". She wishes to only share some of the books with students in her class. Can I create a mechanism for downloading books from a custom repository link? I would send the URL home with the kids and have the parents type it into the app. I would include a couple of books preloaded with the app. I could even provide a sample repository with a sample book if you think it would make any difference. I am trying to come up with a creative solution that gives her the app she wants for her students while protecting the privacy she wishes for some of her content. What are your thoughts?

  • Which C# Book to take?

    - by Fischkopf
    I was searching for a book to learn C#, but now i'm kinda stuck. I found many people asking the same question, and many people gave answers, but there are so many books about C# that it is really hard to decide which one to take. Now i reduced my choice on two books, but I just can't decide between them. Namely, there are: Programming C# 4.0 and C# 4.0 In A Nutshell The first thing I want to know, are these good choices? I'm not completely new to programming, but I just didn't find the right language until know, but i think C# is the one I was searching for. I know all the bassic stuff from Delphi/Java/Python so I think i'm not a complete beginner in programming. Is there anyone out there that read both books and can cleary explain whats the difference between them? I haven't found many reviews and sort of, so I just don't know which one to chose. Or is there any book that is better suiting me?

  • 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!

  • game programming career, vc++ reference and future of it [closed]

    - by Pappu Bacha
    1) I have quite a lot of interest in game programming and I (to my thought) am quite good at programming skills, I have developed some console based animations and text based animation games (like copter-it, snake, and a music visualization), should I invest in game programming? I have 2 years at college left. 2) If I am to pursue a career in game programming, and I select to go only with c++ and DirectX, is it enough? is assembly language necessary? 3) is Visual C++ or MFC dead? should I invest in it or not? 4) I am unable to find any reference book for Visual C++ 2008 or later (just like C++ the complete reference book) I need a book that covers the basic fundamentals and covers the most of the libraries etc.

  • BizTalk Cross Reference Data Management Strategy

    - by charlie.mott
    Article Source: http://geekswithblogs.net/charliemott This article describes an approach to the management of cross reference data for BizTalk.  Some articles about the BizTalk Cross Referencing features can be found here: http://home.comcast.net/~sdwoodgate/xrefseed.zip http://geekswithblogs.net/michaelstephenson/archive/2006/12/24/101995.aspx http://geekswithblogs.net/charliemott/archive/2009/04/20/value-vs.id-cross-referencing-in-biztalk.aspx Options Current options to managing this data include: Maintaining xml files in the format that can be used by the out-of-the-box BTSXRefImport.exe utility. Use of user interfaces that have been developed to manage this data: BizTalk Cross Referencing Tool XRef XML Creation Tool However, there are the following issues with the above options: The 'BizTalk Cross Referencing Tool' requires a separate database to manage.  The 'XRef XML Creation' tool has no means of persisting the data settings. The 'BizTalk Cross Referencing tool' generates integers in the common id field. I prefer to use a string (e.g. acme.country.uk). This is more readable. (see naming conventions below). Both UI tools continue to use BTSXRefImport.exe.  This utility replaces all xref data. This can be a problem in continuous integration environments that support multiple clients or BizTalk target instances.  If you upload the data for one client it would destroy the data for another client.  Yet in TFS where builds run concurrently, this would break unit tests. Alternative Approach In response to these issues, I instead use simple SQL scripts to directly populate the BizTalkMgmtDb xref tables combined with a data namepacing strategy to isolate client data. Naming Conventions All data keys use namespace prefixing.  The pattern will be <companyName>.<data Type>.  The naming conventions will be to use lower casing for all items.  The data must follow this pattern to isolate it from other company cross-reference data.  The table below shows some sample data. (Note: this data uses the 'ID' cross-reference tables.  the same principles apply for the 'value' cross-referencing tables). Table.Field Description Sample Data xref_AppType.appType Application Types acme.erp acme.portal acme.assetmanagement xref_AppInstance.appInstance Application Instances (each will have a corresponding application type). acme.dynamics.ax acme.dynamics.crm acme.sharepoint acme.maximo xref_IDXRef.idXRef Holds the cross reference data types. acme.taxcode acme.country xref_IDXRefData.CommonID Holds each cross reference type value used by the canonical schemas. acme.vatcode.exmpt acme.vatcode.std acme.country.usa acme.country.uk xref_IDXRefData.AppID This holds the value for each application instance and each xref type. GBP USD SQL Scripts The data to be stored in the BizTalkMgmtDb xref tables will be managed by SQL scripts stored in a database project in the visual studio solution. File(s) Description Build.cmd A sqlcmd script to deploy data by running the SQL scripts below.  (This can be run as part of the MSBuild process).   acme.purgexref.sql SQL script to clear acme.* data from the xref tables.  As such, this will not impact data for any other company. acme.applicationInstances.sql   SQL script to insert application type and application instance data.   acme.vatcode.sql acme.country.sql etc ...  There will be a separate SQL script to insert each cross-reference data type and application specific values for these types.

  • best way to reference business objects from presentation layer..?

    - by Vytas999
    I want to develop an enterprise app that includes a WindowsForms presentation layer, middle-tier components for business logic and data access, and a MsSQL Server database. Middle-tier components should contain some business objects and will be called from presentation layer using .NET Remoting. Whitch is the best way (and why) to reference these business objects from presentation layer? a) Create class library project, implementing business objects. Reference this project from presentation layer and middle-tier layer. b) Create interface library project defining business objects. Create class library project implementing interfaces. Reference class library project from middle-tier layer. Reference interface library project from presentation layer. c) Create separate class library projects for middle-tier and presentation layer. Reference corresponding project from presentation layer.

  • Parameter passed by const reference returned by const reference.

    - by Alien01
    Hello, I was reading C++ Faq Second Edition , faq number 32.08 . FAQ says that parameter passed by const reference and returned by const reference can cause dangling reference. But it is ok if parameter is passed by reference and returned by reference. I got it that it is unsafe in case of const reference but how is it safe in case when parameter is non const reference. Last line of FAQ says "Note that if a function accepts a parameter by non-const reference (for example, f(string& s)), returning a copy of this reference parameter is safe because a temporary cannot be passed by non-const reference." Need some insight on this!!

  • PHP Changing Class Variables Outside of Class

    - by Jamie Bicknell
    Apologies for the wording on this question, I'm having difficulties explaining what I'm after, but hopefully it makes sense. Let's say I have a class, and I wish to pass a variable through one of it's methods, then I have another method which outputs this variable. That's all fine, but what I'm after is that if I update the variable which was originally passed, and do this outside the class methods, it should be reflected in the class. I've created a very basic example: class Test { private $var = ''; function setVar($input) { $this->var = $input; } function getVar() { echo 'Var = ' . $this->var . '<br />'; } } If I run $test = new Test(); $string = 'Howdy'; $test->setVar($string); $test->getVar(); I get Var = Howdy However, this is the flow I would like: $test = new Test(); $test->setVar($string); $string = 'Hello'; $test->getVar(); $string = 'Goodbye'; $test->getVar(); Expected output to be Var = Hello Var = Goodbye I don't know what the correct naming of this would be, and I've tried using references to the original variable but no luck. I've come across this in the past, with the PDO prepared statements, see Example #2 $stmt = $dbh->prepare("INSERT INTO REGISTRY (name, value) VALUES (?, ?)"); $stmt->bindParam(1, $name); $stmt->bindParam(2, $value); // insert one row $name = 'one'; $value = 1; $stmt->execute(); // insert another row with different values $name = 'two'; $value = 2; $stmt->execute(); I know I can change the variable to public and do the following, but it isn't quite the same as how the PDO class handles it, and I'm really looking to mimic that behaviour. $test = new Test(); $test->setVar($string); $test->var = 'Hello'; $test->getVar(); $test->var = 'Goodbye'; $test->getVar(); Any help, ideas, pointers, or advice would be greatly appreciated, thanks.

  • Enterprise MDM: Rationalizing Reference Data in a Fast Changing Environment

    - by Mala Narasimharajan
    By Rahul Kamath Enterprises must move at a rapid pace to establish and retain global market leadership by continuously focusing on operational efficiency, customer intimacy and relentless execution. Reference Data Management    As multi-national companies with a presence in multiple industry categories, market segments, and geographies, their ability to proactively manage changes and harness them to align their front office with back-office operations and performance management initiatives is critical to make the proverbial elephant dance. Managing reference data including types and codes, business taxonomies, complex relationships as well as mappings represent a key component of the broader agenda for enabling flexibility and agility, without sacrificing enterprise-level consistency, regulatory compliance and control. Financial Transformation  Periodically, companies find that processes implemented a decade or more ago no longer mirror the way of doing business and seek to proactively transform how they operate their business and underlying processes. Financial transformation often begins with the redesign of one’s chart of accounts. The ability to model and redesign one’s chart of accounts collaboratively, quickly validate against historical transaction bases and secure business buy-in across multiple line of business stakeholders, while continuing to manage changes within the legacy general ledger systems and downstream analytical applications while piloting the in-flight transformation can mean the difference between controlled success and project failure. Attend the session titled CON8275 - Oracle Hyperion Data Relationship Management: Enabling Enterprise Transformation at Oracle Openworld on Monday, October 1, 2012 at 4:45pm in Ballroom A of the InterContinental Hotel to learn how Oracle’s Data Relationship Management solution can help you stay ahead of the competition and proactively harness master (and reference) data changes to transform your enterprise. Hear in-depth customer testimonials from GE Healthcare and Old Mutual South Africa to learn how others have harnessed this technology effectively to build enduring competitive advantage through business process innovation and investments in master data governance. Hear GE Healthcare discuss how DRM has enabled financial transformation, ERP consolidation, mergers and acquisitions, and the alignment reference data across financial and management reporting applications. Also, learn how Old Mutual SA has upgraded to EBS R12 Financials and is transforming the management of chart of accounts for corporate reporting. Separately, an esteemed panel of DRM customers including Cisco Systems, Nationwide Insurance, Ralcorp Holdings and Mentor Graphics will discuss their perspectives on how DRM has helped them address business challenges associated with enterprise MDM including major change management initiatives including financial transformations, corporate restructuring, mergers & acquisitions, and the rationalization of financial and analytical master reference data to support alternate business perspectives for the alignment of EPM/BI initiatives. Attend the session titled CON9377 - Customer Showcase: Success with Oracle Hyperion Data Relationship Management at Openworld on Thursday, October 4, 2012 at 12:45pm in Ballroom of the InterContinental Hotel to interact with our esteemed speakers first hand.

  • Class instance clustering in object reference graph for multi-entries serialization

    - by Juh_
    My question is on the best way to cluster a graph of class instances (i.e. objects, the graph nodes) linked by object references (the -directed- edges of the graph) around specifically marked objects. To explain better my question, let me explain my motivation: I currently use a moderately complex system to serialize the data used in my projects: "marked" objects have a specific attributes which stores a "saving entry": the path to an associated file on disc (but it could be done for any storage type providing the suitable interface) Those object can then be serialized automatically (eg: obj.save()) The serialization of a marked object 'a' contains implicitly all objects 'b' for which 'a' has a reference to, directly s.t: a.b = b, or indirectly s.t.: a.c.b = b for some object 'c' This is very simple and basically define specific storage entries to specific objects. I have then "container" type objects that: can be serialized similarly (in fact their are or can-be "marked") they don't serialize in their storage entries the "marked" objects (with direct reference): if a and a.b are both marked, a.save() calls b.save() and stores a.b = storage_entry(b) So, if I serialize 'a', it will serialize automatically all objects that can be reached from 'a' through the object reference graph, possibly in multiples entries. That is what I want, and is usually provides the functionalities I need. However, it is very ad-hoc and there are some structural limitations to this approach: the multi-entry saving can only works through direct connections in "container" objects, and there are situations with undefined behavior such as if two "marked" objects 'a'and 'b' both have a reference to an unmarked object 'c'. In this case my system will stores 'c' in both 'a' and 'b' making an implicit copy which not only double the storage size, but also change the object reference graph after re-loading. I am thinking of generalizing the process. Apart for the practical questions on implementation (I am coding in python, and use Pickle to serialize my objects), there is a general question on the way to attach (cluster) unmarked objects to marked ones. So, my questions are: What are the important issues that should be considered? Basically why not just use any graph parsing algorithm with the "attach to last marked node" behavior. Is there any work done on this problem, practical or theoretical, that I should be aware of? Note: I added the tag graph-database because I think the answer might come from that fields, even if the question is not.

  • Looking for good Regex book

    - by Cyberherbalist
    I've been trying to get a good grounding with Regular Expressions, and am looking for a single book to do so. I've been going through Amazon.com's listings on this subject, and I've identified a few possibilities, but am unsure which would be best for a C# developer who can write very simple Regexs, but wants to learn more. On a scale of 0-9 where 0 is knowing how to spell "Regex" but nothing else, and 9 where I could write a book on the subject out of my own head, I would place myself at 2. Which of the following would be your choice: Mastering Regular Expressions by Jeffrey E F Friedl Regular Expressions Cookbook by Jan Goyvaerts and Steven Levithan Sams Teach Yourself Regular Expressions in 10 Minutes by Ben Forta Beginning Regular Expressions (Programmer to Programmer) by Andrew Watt Regular Expression Recipes for Windows Developers: A Problem-Solution Approach by Nathan A. Good Regular Expression Recipes: A Problem-Solution Approach by Nathan A. Good Now, according to Amazon, "Regular Expressions Cookbook" (REC) above is rated the highest according to user ratings, but only based on 20 reviews. The first one, "Mastering Regular Expressions" (MRE) is rated second based on 140 reviews. This alone suggests that MRE might be by far the best one. But is it best for a relative beginner? Would I perhaps be better getting "Beginning Regular Expressions" (BRE) instead, to start with? Please help me resolve my confusion!

  • My Expert F# Book has now arrived!

    - by MarkPearl
    So it has finally arrived from Amazon. Expert F# by Don Syme, Adam Granicz & Antonio Cisternino. I got a note from the post office yesterday that I needed to collect a package from their offices. After paying a 10% customs fee (that I wasn’t expecting) I had my new Yellow & Black F# Book… it’s so shinny. Trust my luck though – I have a few university assignments due this week as well as a crazy week of work so it has been sitting on my desk for a day and I haven’t managed to get into it. Eventually I managed to take a few minutes this evening to page through it and it looks really good. I can’t wait! So my goal this week is to cover Chapter 2 (by the end of the weekend) and put the appropriate posts up. F# is slowly working on me but I am keen to get a deeper understanding of the language which I am hoping this book will help me achieve.

  • Book Review: Professional WCF 4

    - by Sam Abraham
    My Investigation of WCF internals have set the right stage to revisit Professional WCF 4 by Pablo Cibraro, Kurt Claeys, Fabio Cozzolino and Johann Grabner. In this book, the authors dive deep into all aspects of the WCF API in a reading targeted towards intermediate and advanced developers. Book quality so far as presentation, code completeness, content clarity and organization was superb. The authors have taken a hands-on approach to thoroughly covering the WCF 4.0 API with three chapters totaling 100+ pages completely dedicated to business cases with downloadable source code readily available. Chapter 1 outlines SOA best-practice considerations. Next three chapters take a top-down approach to the WCF API covering service and data contracts, bindings, clients, instancing and Workflow Services followed by another carefully-thought three chapters covering the security options available via the WCF API. In conclusion, Professional WCF 4.0 provides a thorough coverage of the WCF API and is a recommended read for anybody looking to reinforce their understanding of the various features available in the WCF framework. Many thanks to the Wiley/Wrox User Group Program for their support of our West Palm Beach Developers’ Group.   All the best, --Sam

  • Best Java Book(s) for an Experienced Developer

    - by Steven Elliott Jr
    I have been a .NET developer now for about the past 5/6 years give or take. I have never done any professional Java development and the last time I really touched it was probably back in college. I have been toying with the Scala language a little bit but nothing serious. Recently, I've been offered an opportunity to do some pretty cool work, but using Java instead of .NET. I think I can get by alright with my current skill set, meaning I already know how to program well and am familiar with languages such as C# and C++, etc. So, the syntax and all that language stuff are really not a problem. What I need is a really good reference book and a book about how to think in Java. Each language/Framework/Stack tries to address things a certain way and I'm sure Java is no different. What are some great Java books that you simply can't live without? Are there any books that talk about the most important parts of Java that must be understood before all else? As a side note, I will be doing mostly Java web development. Not really 100% on what types of stuff they are using for persistence, framework, server, etc. Thanks again for the consideration.

  • Farseer Physics Samples and Krypton how to reference game

    - by Krell
    I'm sure this is totally simple and yes I am new at this. I am trying to set up Krypton inside farseer. 1. create a new Krypton engine in my sub screen aka AdvancedDemo1 : PhysicsGameScreen, IDemoScreen Via this.krypton = new KryptonEngine(this, "KryptonEffect"); The problem is the KryptonEngine(this wants reference to Game game, I cant seem to reference it from FarseerPhysicsGame : Game So how would I do that? or 2. I can put it directly in FarsserPhysicsGame but again I cant seem to figure out how to reference FarseerPhysicsGame in AdvancedDemo1. or 3. I can put it inside the public FarseerPhysicsGame() and do Componenets.Add(krypton) [which works] HOWEVER I cant figure out how to reference the compoenet once it is added. You should be able to stop reading here , but for more detail I simply took the Farseer XNA Samples went into FarseerPhysicsGame.cs and deleted all the screens and menus except AdvancedDemo1 so there is one option and I just click that to load into the advancedDemo1 and thats where I want to put the lights from krypton. Thanks. Edit: Figured out 1 solution though I am still curious about others. Solution 1 I was able to use ScreenManager.Game(not sure why it was there but Ill try to figure it out later)
