  • Relationship between TDD and Software Architecture/Design

    - by Christopher Francisco
    I'm new to TDD and have been reading the theory since applying it is more complicated than it sounds when you're learning by yourself. As far as I know, the objective is to write test cases for each requirement and run the test so it fails (to prevent a false positive). Afterward, you should write the minimum amount of code that can pass the test and move to the next one. That being said, is it true that you get a fast development, but what about the code itself? this theory makes me think you are not considering things like abstraction, delegation of responsibilities, design patterns, architecture and others since you're just writing "the minimum amount of code that can pass the test". I know I'm probably wrong because if this were true, we'd have a lot of crappy developers with poor software architecture and documentation so I'm asking for a guide here, what's the relationship between TDD and Software Architecture/Design?

  • Synchronising tables across remote Access databases

    - by Paul H
    Hi folks, I'm helping out a business by providing an Access DB to manage requests of various types. As they are a construction company, they have one machine in an 'office' on the building site, plus 3 based in their main office. The machine on site has no internet connectivity. Is there any (reasonably simple) way to synchronise these databases every so often? I realise the tables could be merged, but each has an autoincrement field which must be synced between instances (i.e. when merging two tables the autoincrement should be reassigned based on the combination of records). Cheers in advance, Paul

  • SQL 2008 Database tuning advisor won't start

    - by Andrew Hancox
    For some reason I can't get DTA to connect to my development machine. It connects to a remote DB just fine but when I point it to my dev machine I get an error saying: Failed to initialize MSDB database for tuning (exit code: -1073741819). I'm pretty sure it's not a permissions issue since I've used profiler to capture what it's doing and all of the commands it's run so far look fine and are being run under my account which is associated with the sysadmin role, when I run them in sql management studio they go through fine. I'm pretty convinced that the problem is related to creating the objects in MSDB that are used by DTA but I tried creating these manually (I found scripts on the web) and it just seems to push the problem along the line slightly. I'm going out of my mind - have even tried reinstalling SQL but that's not fixed it. I'm using SQL 2008 with SP1 (10.0.2531) on windows server 2008 (patched up to date). SAVE ME!!!!!

  • Where do you store the private key for your code signing certificate?

    - by flipdoubt
    I recently acquired a code signing certificate for my employer, but I am not the InstallShield developer who will sign the binaries before distribution. I know I can export the certificate along with its private key, but where do I store it so the InstallShield developer can install it on his machine? Should I remove it from my machine once I give it to the person doing the signing? Where do I store the master copy? Obviously, source control is not the best place, unless I lock down that directory in SVN.

  • Getting a solid understanding of Linux fundamentals

    - by JoshEarl
    I'm delving into the Linux world again as a diversion from my Microsoft-centric day job, and every time I tackle a new project I find it a frustrating exercise in trial and error. One thing that I always try to do when learning something new is figure out what the big pieces are and how they work together. I haven't yet come across a resource that explains Linux at this level. Resources seem to be either aimed at the barely computer literate crowd (Linux doesn't bite. Promise!) or the just compile the kernel and make your own distro crowd. I'm looking for a "JavaScript: The Good Parts" type of road map that doesn't necessarily answer all my questions so much as help me understand what questions I need to be asking. Any suggestions?

  • To maximize chances of functional programming employment

    - by Rob Agar
    Given that the future of programming is functional, at some point in the nearish future I want to be paid to code in a functional language, preferably Haskell. Assuming I have a firm grasp of the language, plus all the basic programmer attributes (good communication skills/sense of humour/hygiene etc), what should I concentrate on learning to maximize my chances? Are there any particularly sought after libraries I should know? Alternatively, would another language be a better bet, say F#? (I'm not too fussed about the kind of programming work, so long as it's reasonably interesting and reasonably well paid, and with nice people)

  • Prologue…

    - by Chris Stewart
    Hi all,                 This is the beginning of my blog. I have been a software developer for going on 11 years using the Microsoft toolset (primarily VB 5, VB 6, VB.net and SQL Server 6, 7, 2000, 2005, 2008). My coding interests are C#, ASP.net, SQL and XNA. Here I will post my musings, things of interest, techie babble and sometimes random gibberish. My hope for this blog is to document my learning experiences with C#, help, encourage and in some way be useful to those who come after me. Thanks for reading!

  • Alternative to pyGame ?

    - by stighy
    Hi, i'm learning something about game programming from a book about "pyGame". pyGame is simple, but... python is a little complex and different from my previous knoweledge about programming. I know "classical" language: C# (also C/C++), Java ... I know a lot of people love Python but for me is a little harder to learn! So i'm looking something like "pyGame" but for java or for c# ... A library with which i can do almost the same thing i can do with pygame (so .. do more with less code ... and headhace). Thank you Ps: excuse my "poor" english!

  • Upgrading in java web development

    - by Vladimir Ivanov
    I'm a java web developer for nearly 3 years. Always trying to learn more and be better but still I feel that the amount of knowledge is not that good as I want. The knowledge in some places still seems to be non-systematic and don't provide a very strong base to solve the problems as good as I want to do it. The example I have is my senior developer, whose solutions are always more efficient and beautiful. So, the question is rather simple and hard the same time. What is the right way to get my knowlege be more systematic and therefore improve it's quality. I understand that there is no practically good answer for the all java programming, so let's focus on the modern java web or nearly web technologies: JSF 2.0 JPA2 and Hibernate as persistence provider Web services and Java SE as a core. What methodologies or books or learning technics lead to the strong knowledge base within the given knowledge area?

  • Turbo C++ to Visual Studio 2010 migration [closed]

    - by BigGenius
    OK, based on my previous questions and your help., I have gone to install Visual Studio Express. But now problem is, the programs which I successfully code at home on Visual Studio don't run on Turbo C++ compiler at school (assuming I type the program instead of exporting code). Is there anything I can do? Also I am just learning basic syntax and data handling, loops, structures, arrays and all. But Visual Studio has auto completion and pretty typing (which may be advantageous) but crap for a beginner getting hold on to language. Sorry, if I have been unclear. But what should I do? This will make me lazy programmer and will reflect in my grades. Is there any other IDE, which I can use, very similar to Turbo C++ and able to run in Windows 7 in fullsreen mode.

  • Provisioning Videos

    - by Owen Allen
    There are a couple of new videos up on the Oracle Learning Youtube channel about Ops Center's provisioning capabilities. Simon Hayler does a walkthrough of a couple of different procedures. The first video shows you how to provision Oracle Solaris zones. It explains how to create an Oracle Solaris Zone profile, and then how to apply it (using a deployment plan) to a target system. The second video shows you how to provision an x86 server with Oracle Solaris. This uses a very similar process - you create a OS provisioning profile, then use a deployment plan to apply it to the target hardware. The documentation goes over OS provisioning and zone creation in the Feature Guide, if you're looking for additional information.

  • In Scrum, should tasks such as development environment set-up and capability development be managed as subtasks within actual user stories?

    - by Asim Ghaffar
    Sometimes in projects we need to spend time on tasks such as: exploring alternate frameworks and tools learning the framework and tools selected for the project setting up the servers and project infrastructure (version control, build environments, databases, etc) If we are using User Stories, where should all this work go? One option is to make them all part of first user story (e.g. make the homepage for application). Another option is to do a spike for these tasks. A third option is to make task part of an Issue/Impediment (e.g. development environment not selected yet) rather than a user Story.

  • GnuPG + Webservice + ASP.NET

    - by Karol Bladek
    Hi! I'm exhausted. I have installed GnuPG and exported secret key, and two public keys (my own and one of my client) from another instance of GnuPG. I try to configure 'my encrypting/decrypting' method on the local machine. When I run encrypting method from a little console application it works good. When I run this (same! - with the same body) method from my webservice on my local machine ... I have an ExitCode = 2. Happy in fact of catching the error message, but unhappy with their body. "gpg: no default secret key: secret key not available gpg: XXXXXXXXXXXXXXXX.xml: sign+encrypt failed: secret key not available" What should I do? Whats wrong? Best regards, Karol Bladek

  • JavaScript "Cannot retrieve referenced URL"

    - by jb
    I have JavaScript inside a .wsf file and I'm getting the error: C:\bin\LDLSInfo.wsf(53, 34) Windows Script Host: Cannot retrieve referenced URL: S:\tools\JScript\lib\StandardWSH.js At line 53, it says <script language="JScript" src="S:\tools\JScript\lib\StandardWSH.js"/> I know that LDLSInfo.wsf (the main script) and StandardWSH.js (the script to load) both work fine, because I've ran them from a different machine. It works fine on one machine and not on the other, both are Windows 7 x64 computers. So I'm thinking I'm missing some .dll's. Thanks for the help, -jb

  • How are .NET 4 GUIDs generated?

    - by mafutrct
    I am aware of the multitude of questions here as well as Raymond's excellent (as usual) post. However, since the algorithm to create GUIDs was changed apparently, I found it hard to get my hands on any up-to-date information. The MSDN seems to try and provide as few information as possible. What is known about how GUIDs are generated in .NET 4? What was changed, and how does it affect the security ("randomness") and integrity ("uniqueness")? One specific aspect I'm interested in: In v1, it seems to be about impossible to generate the same GUID on a single machine again since there was a timestamp and counter involved. In v4, this is no longer the case (I was told), so the chance to get the same GUID on a single machine ... increased?

  • How could RDBMSes be considered a fad?

    - by StuperUser
    Completing my Computing A-level in 2003 and getting a degree in Computing in 2007, and learning my trade in a company with a lot of SQL usage, I was brought up on the idea of Relational Databases being used for storage. So, despite being relatively new to development, I was taken-aback to read a comment (on Is LinqPad site quote "Tired of querying in antiquated SQL?" accurate? ) that said: [Some devs] despise [SQL] and think that it and RDBMS are a fad Obviously, a competent dev will use the right tool for the right job and won't create a relational database when e.g. flat file or another solution for storage is appropriate, but RDBMs are useful in a massive number of circumstances, so how could they be considered a fad?

  • Memory mapped files causes low physical memory

    - by harik
    I have a 2GB RAM and running a memory intensive application and going to low available physical memory state and system is not responding to user actions, like opening any application or menu invocation etc. How do I trigger or tell the system to swap the memory to pagefile and free physical memory? I'm using Windows XP. If I run the same application on 4GB RAM machine it is not the case, system response is good. After getting choked of available physical memory system automatically swaps to pagefile and free physical memory, not that bad as 2GB system. To overcome this problem (on 2GB machine) attempted to use memory mapped files for large dataset which are allocated by application. In this case virtual memory of the application(process) is fine but system cache is high and same problem as above that physical memory is less. Even though memory mapped file is not mapped to process virtual memory system cache is high. why???!!! :( Any help is appreciated. Thanks.

  • Bring Office 2003 Menus Back to 2010 with UBitMenu

    - by Matthew Guay
    Are you having trouble getting used to the Ribbon interface in Office 2010?  Here’s how you can roll back the clock a bit and bring back the familiar menus and toolbars from 2003. The Office 2007 Ribbon was both praised and criticized.  While many users felt they were more productive with the new interface, others felt frustrated searching for commands they had memorized in older versions of Office.  Now, with Office 2010, the ribbon interface has been brought to every app in the Office suite, and is integrated into many newer programs from Microsoft. If you’re moving from Office 2003, using UBitMenu allows you to add the old familiar menus back along with the new Ribbon interface for an easier learning curve. Also, with the customizability of Office 2010, we can strip away the extra Ribbon tabs to make it more like 2003. Get the 2003 Menus and Toolbars Back in Office 2010 Download UBitMenu (link below), and install as normal.  Make sure all of your Office programs are closed during the installation.  This handy utility is very small, and installed amazingly quick. Open Word, Excel, or PowerPoint and there’s now a new Menu tab beside Home in the Ribbon.  Now you can access all of your favorite old Office commands in the familiar menus, and access many of the newer Office features such as SmartArt.   Here’s a close-up of the toolbar.  Notice that the layout is very similar to that of Word 2003. You can access all of the new Transitions in PowerPoint 2010 from the menu bar.   The menu in Excel even included support for the new PivotTable and PivotCharts Wizard. One problem we noticed was that the toolbars were condensed to a drop-down menu if the Office window was less than 870px wide.  This may be a frustration to users with low-resolution displays, and you might want to use the Office Apps maximized. Get Rid of the Ribbon Now that you’ve got the old menus back, you can get rid of the extra ribbon tabs if you’d like.  Office 2010 lets you customize your ribbon and remove tabs, so let’s get rid of all the other tabs except for our new Menu tab.  In our example we’re using Word, but you can do it in Excel or PowerPoint the same way. Click the File tab and select Options. Alternately, in the Menu tab, select Tools and then Word Options. Select Customize Ribbon on the left sidebar, then uncheck the boxes beside all the ribbon tabs you want to hide on the right.  Click Ok when you’re finished. While you’re at it, you can change the default color scheme as well. Note: The color change will automatically change the color scheme in all of the Office apps, so you’ll only need to do that once. Now the ribbon only has 2 tabs…the File tab for the new Backstage View, and the UBitMenu tab we just installed.  It almost has the appearance Word 2003, but with the new features of Word 2010!  You’ll need to repeat these steps in Excel and PowerPoint if you want to customize their ribbon the same.   Conclusion If you’ve been having a hard time getting used to Office 2010, UBitMenu is a great way to get familiar with the new interface, or simply stay productive with your old tricks.  We do wish it supported the other Office applications like OneNote and Outlook. That doesn’t make it a deal breaker though, it can make the learning curve easier in Word, PowerPoint, and Excel. UBitMenu is free for personal use, and available at a very reasonable price for businesses. If you’re using Office 2007 and not a fan of the Ribbon, UBitMenu works for it as well.

  • Concrete examples of Python's "only one way to do it" maxim

    - by Charles Roper
    I am learning Python and am intrigued by the following point in PEP 20 The Zen of Python: There should be one-- and preferably only one --obvious way to do it. Although that way may not be obvious at first unless you're Dutch. Could anyone offer any concrete examples of this maxim? I am particularly interested in the contrast to other languages such as Ruby. Part of the Ruby design philosophy (originating with Perl, I think?) is that multiple ways of doing it is A Good Thing. Can anyone offer some examples showing the pros and cons of each approach. Note, I'm not after an answer to which is better (which is probably too subjective to ever be answered), but rather an unbiased comparison of the two styles.

  • March 2010 Chicago Architects Group Wrap Up

    - by Tim Murphy
    I would like to thank everyone who came out to last night’s event and especially thank Mike Vogt for the presentation. I think at first everyone glassed over since very few of us spend a lot of time with Integration Architecture and most of us live more in the application architecture space.  Learning about subject like BPEL and BPMN was refreshing. The discussion after Mike’s talk was lively and I think that everyone came away with a good idea of areas they might want to know more about.  People stuck around long after the meeting was over. If you are interested in the topic you can find the slides here. Be sure to join us next month when Matt Hidinger talks about Onion Architecture.  Details are coming soon. del.icio.us Tags: CAG,Chicago Architects Group
