• Blog...Dead & New Address

  - by Derek Comingore

  Hi Folks! For a while I was attempting (probably the correct word) to keep both this blog as well as my SQL Server Magazine SQL Server BI blog current. Working on growing B.I. Voyage , speaking, writing, and blogging is quite the work load. And so this blog suffered as a result. THANK YOU all who read my blog here on SQLTeam.com, I intend to leave it live for those who might benefit from its content at a later date. My consolidated, single blog can be found at http://www.sqlmag.com/blogs/sqlserverbi.aspx . Cheers, Derek

• How to refactor an OO program into a functional one?

  - by Asik

  I'm having difficulty finding resources on how to write programs in a functional style. The most advanced topic I could find discussed online was using structural typing to cut down on class hierarchies; most just deal with how to use map/fold/reduce/etc to replace imperative loops. What I would really like to find is an in-depth discussion of an OOP implementation of a non-trivial program, its limitations, and how to refactor it in a functional style. Not just an algorithm or a data structure, but something with several different roles and aspects - a video game perhaps. By the way I did read Real-World Functional Programming by Tomas Petricek, but I'm left wanting more.

• Build one to throw away vs Second-system effect

  - by m3th0dman

  One one hand there is an advice that says "Build one to throw away". Only after finishing a software system and seeing the end product we realize what went wrong in the design phase and understand how we should have really done it. On the other hand there is the "second-system effect" which says that the second system of the same kind that is designed is usually worse than the first one; there are many features that did not fit in the first project and were pushed into the second version usually leading to overly complex and overly engineered. Isn't here some contradiction between these principles? What is the correct view over the problems and where is the border between these two? I believe that these "good practices" are were firstly promoted in the seminal book The Mythical Man-Month by Fred Brooks. I know that some of these issues are solved by Agile methodologies, but deep down, the problem is still the principles still stand; for example we would not make important design changes 3 sprints before going live.

• Car Modelling for race game

  - by Mert Toka

  I am taking Computer Graphics course this semester and we have a video game competition. I am making racing game with simulated dynamics. Our professor told us that we don't have to do much of a modelling but since we haven't started the gaming part and since I have free time I want to model the car. My question is firstly which software do you recommend to design game components? I know Maya right now. Secondly, if I design the car or any other part, what should its polygon count in order to run game smoothly? I can design pretty much everything but I assume that it is hard to design low-poly models.

• Are certification courses worth it?

  - by Bill Williams

  I'm planning on getting certification in Database Development for SQL Server (MSTC - 70-433). I'm a junior level report writer at a new job and the company is offering to pay the majority, if not all, of training course fees. The course is five days. I noticed that MS has a self-paced training kit (book) that I could use. I'm wondering if this would be a better option because it will allow me to go as quick as possible. I've also heard about video training sessions (Lynda.com) but they seem to go at slow pace. My questions are: What should I expect at a certification course? Is it hands-on training? Small classes with personal feedback or not? Would I be better off learning at my own pace using the training kit? (I'd rather this not turn into a certifications are pointless discussion..)

• Creating Google sitemap.xml , is it okay for the images to be wrapped in url tags?

  - by AzizAG

  I'm using a tool to generate the sitemap.xml file for me, it started to crawl my website, got the pages and all images, but when exporting it, I review the xml(to make sure nothing is wrong) and I noticed that the images in my website are wrapped in url tags(I think it should be in image tags). See this: <url><loc>http://mywebsite.com/images/12.jpg</loc><lastmod>2012-05-23T13:39:02+00:00</lastmod><changefreq>weekly</changefreq><priority>0.50</priority></url> Shouldn't it be wrapped in image tag?(just like videos wrapped in video tag) Thanks.

• Are all "Important security updates", updates to already installed packages?

  - by Omnicomment

  I'm running 12.04, and I've never downloaded any drivers for the installation of any peripheral devices. Yet, I noticed a fair few "Important security updates" involving drivers/utilities for HP devices/software. I understand if the default installation of Ubuntu came with a set of drivers for these devices - and the update manager, having noticed that they live on my system, went and found newer versions, but still - given I don't use any devices - I'm either forced to download an irrelevant update, sift through the updates to check applicability, or turn off Update Manager altogether: none of which are desirable. First; the obvious - can someone confirm that the list of "Important security updates" on the server that Update manager connects to, is not actually populated with every patch ever written (i.e. for all Ubuntu packages regardless of whether they're installed or not)? Unlikely, but..

• Share on Facebook does not show thumbnail images

  - by matt_tm

  I have a PHP application which has a "Share on Facebook" button that, On the development server shows the thumbnail images correctly and allows the user to select between them On the live server, it does NOT show the thumbnail images at all. The relevant portion of the .htaccess file is: # Set up caching on media files for 2 days <FilesMatch "\.(gif|jpg|jpeg|png|flv)$"> ExpiresDefault A172800 Header append Cache-Control "public" </FilesMatch> I'm using the exact same set of php files and .htaccess, but the server configuration is different. What could be causing this? Note that the text appears fine. Edit1 We are also doing some URL rewriting related to images in the .htaccess (on both servers): ... RewriteRule ^.*/content/image/(.*)$ content/image/$1 [L] ... RewriteRule ^.*/images/(.*)$ images/$1 [L] ... Would that be somehow making a difference? Images appear fine all throughout the site. (I posted this question earlier as http://stackoverflow.com/questions/4142597/share-on-facebook-does-not-show-thumbnail-images) )

• Visual Studio 2010 Service Pack 1 Beta Released!

  - by Jim Duffy

  Just thought I’d pass on the word that the Visual Studio 2010 Service Pack 1 Beta is now available to download. VS2010 SP1 Beta ships with a go live license which means you can start using it for production work though I’m not sure I’m going to be that brave until I check it out a bit first. Jason Zanders has a blog post outlining the new features/fixes included in the beta. Here are a couple BREAKING news items you’ll want to TakeNote of… VS2010 SP1 Beta BREAKS ASP.NET MVC 3 RC Razor IntelliSense. A new ASP.NET MVC 3 RC2 installer will be released very soon that will allow you to upgrade in-place. VS2010 SP1 Beta BREAKS the Visual Studio Async CTP. A work around is being worked on but for now if you’re working with the Async CTP then stick with VS2010 RTM. Have a day.

• How to Install Nvidia Drivers

  - by Richard Rodriguez

  I just ordered the Nvidia GTX 560 card, which should arrive tomorrow. I have a dilemma, though. Should I keep using the driver which is available in "additional drivers" in Ubuntu (10.10), or should I install the driver from the nvidia site? NOTE - The methods to install explained here apply to all Nvidia, Ati & Intel video cards The latest driver available at the nvidia site: LINUX X64 (AMD64/EM64T) DISPLAY DRIVER Version: 280.13 Certified Release Date: 2011.08.01 Operating System: Linux 64-bit Language: English (U.S.) File Size: 52.4 MB I should point out that I don't need the card to unleash its full potential in Ubuntu (I have Windows for gaming, other HDD), I just need it to work properly, that meaning the power saving should work (I don't want the card to overheat for no reason), also I would like the fans to work at proper speeds, etc. So which driver is the best for me?

• Sound unavailable every other session

  - by Oxwivi

  On my desktop running Oneiric, sometimes there's no sound at all, but it would work normally at other times. My setup is built ground-up from minimal Ubuntu, but since sounds work fine, at times, I don't think it is a backend dependency issue. When it works, it will play anything from regular audio files and movies to YouTube Flash players. For the record, I installed LXDE with the alsa-base and alsa-utils packages which are the only audio-related dependencies for the lubuntu-desktop. For a while, I also used persistent Oneiric live USB, and do not recall any sound issues. It's one thing to not play sound entirely, but playing sound only under some very unclear circumstances is something else. Please help me diagnose it.

• Can't find ALL wireless networks, just my neighbours

  - by motoringeek

  Been playing with live discs since 10.10 but now have gone ahead and dual booted. I have a Acer 5742z with a Nplify 802.11b/g/n wireless connection. The install went well and drivers seem to be working. BUT, although wireless detects some local networks it doesn't find mine. I have WPA-PSK security on my modem, could this be the problem?? I don't want to change my modem settings as all my other WIFI devices are contected to it. So I need help in finding my home network. A step by step guide would be useful. I am using Windows 7 now to write this but would love it if I could use Ubuntu online. I only can when I connect an Ethernet cable. Thanks in advance.

• When is a Use Case layer needed?

  - by Meta-Knight

  In his blog post The Clean Architecture Uncle Bob suggests a 4-layer architecture. I understand the separation between business rules, interfaces and infrastructure, but I wonder if/when it's necessary to have separate layers for domain objects and use cases. What added value will it bring, compared to just having the uses cases as "domain services" in the domain layer? The only useful info I've found on the web about a use case layer is an article by Martin Fowler, who seems to contradict Uncle Bob about its necessity: At some point I may run into the problems, and then I'll make a Use Case Controller - but only then. And even when I do that I rarely consider the Use Case Controllers to occupy a separate layer in the system architecture. Edit: I stumbled upon a video of Uncle Bob's Architecture: The Lost Years keynote, in which he explains this architecture in depth. Very informative.
