• How to use the Netduino Go Piezo Buzzer Module

  - by Chris Hammond

  Originally posted on ChrisHammond.com Over the next couple of days people should be receiving their Netduino Go Piezo Buzzer Modules , at least if they have ordered them from Amazon. I was lucky enough to get mine very quickly from Amazon and put together a sample project the other night. This is by no means a complex project, and most of it is code from the public domain for projects based on the original Netduino. Project Overview So what does the project do? Essentially it plays 3 “tunes” that...(read more)

• Scrubbing a DotNetNuke Database for user info and passwords

  - by Chris Hammond

  If you’ve ever needed to send a backup of your DotNetNuke database to a developer for testing, you likely trust the developer enough to do so without scrubbing your data, but just to be safe it is probably best that you do take the time to scrub. Before you do anything with the SQL below, make sure you have a backup of your website! I would recommend you do the following. Backup your existing production database Restore a backup of your production database as a NEW database Run the scripts below...(read more)

• Adding Facebook Comments using Razor in DotNetNuke

  - by Chris Hammond

  The other day I posted on how to add the new Facebook Comments to your DotNetNuke website. This worked okay for basic modules that only had one content display, but for a module like DNNSimpleArticle this didn’t work well as the URLs for each article didn’t come across as individual URLs because of the way the Facebook code is formatted. When displaying the Comments I also only wanted to show them on individual articles, not on the main article listing. There is actually a pretty easy fix though...(read more)

• Integrating Facebook Comments into your DotNetNuke Pages

  - by Chris Hammond

  Last week Facebook announced a new feature that websites can use to get Facebook Comments onto their web pages . I thought this was interesting as I have a few car racing sites that are using Forums, but also have the DNNSimpleArticle module for main page content. The forums are active, but the DNNSimpleArticle module doesn’t allow for comments as of right now (or in the foreseeable future) so I started to look into the Facebook comments a bit. From a quick read of their blog post/announcement it...(read more)

• Upcoming DotNetNuke Training for January 2011

  - by Chris Hammond

  With the New Year, why not resolve to learn more about DotNetNuke ? DotNetNuke is the most successful and widely adopted open source project on the Microsoft Stack. Its been around for eight years and isn’t going away anytime soon. While the software itself is written in VB.Net you are not limited to VB.Net when developing custom extensions for the platform, in fact, when I do my module development I do it primarily in C# out of preference. If you’re a developer out there who shuns learning a framework...(read more)

• Learning about C Bitshift Operators

  - by Chris Hammond

  So I was doing some reading tonight on my Nerdkit , I had planned to actually do some playing around with it, but decided just to read a bit. I’ve never coded in C, I did C++ in College (not very well) and do most of my development in C# these days (when I’m doing code, mostly for fun). While all similar, there are a few differences, so doing things in C is a learning experience. There was some practice questions for AND and OR using Binary. Here are some examples. When comparing binary with AND ...(read more)

• Weblogs.asp.net has a problem, it is spam

  - by Chris Hammond

  Is anyone at Microsoft listening to the SPAM problem here on Weblogs.asp.net? My “ Can anyone do anything about the spam here on weblogs.asp.net? ” post from October got over 12 spam comments posted to it in the past 24 hours. I have comments all moderated, but that just means I have a crapload of work to do each time people comment. Also, when you click on a link from a comment notification email you are taken to an insecure site warning due to an invalid SSL Cert. We really just need some updates...(read more)

• Installing DotNetNuke using WebMatrix

  - by Chris Hammond

  Last week Microsoft released a new tool called WebMatrix, a tool for developing web applications and easily installing existing web applications. You can learn more about WebMatrix by visiting http://www.microsoft.com/web/webmatrix/ . What does this have to do with DotNetNuke ? Well WebMatrix makes installing DotNetNuke very easy! Even easier than before when just using the Web Platform Installer also from Microsoft. To be honest, using the Web Platform Installer alone unfortunately doesn’t work...(read more)

• DotNetNuke 6 beta released

  - by Chris Hammond

  DotNetNuke 6 is coming, DotNetNuke 6 is coming! That’s right, we’re getting close, close enough that we had our first “beta” for DNN6 today. While we’ve had a couple of CTP (community technology preview) releases, the beta today has quite a bit of things wrapped up and addressed. There are a number of new things coming in DotNetNuke 6, and rather than try to explain them all I’ll point you to Joe Brinkman’s blog post from this morning . The biggest thing is that most of the Admin and Module settings...(read more)

• DNNWorld 2012, The Trailer

  - by Chris Hammond

  Some people in the asp.net community love to hate on DotNetNuke ( see Shaun's latest blog post comments ), that’s fine, the rest of us are off having a good time with it and the community! Check out the trailer for DNNWorld 2012, coming up in Orlando Florida in October (you can register for DNN World at http://dnnworld.dotnetnuke.com ). For those of you who love to hate on DNN, I challenge you to give it another look. A lot has changed with the platform in the past 10 years, most recently in the...(read more)

• What is the difference between apt-get and dpkg?

  - by William F. Hammond

  Both apt-get and dpkg can be used to install and remove packages. When to use which? Context: I'm in stuck in package limbo between 10.04.4 LTS and 12.04.1 LTS after an attempted upgrade via the package manager. For example, to fix things I wanted to remove "skype" so that things it depends on could be freed up. But "aptitude" (my normal package management tool) refused to remove it. The advice at http://administratosphere.wordpress.com/2011/11/02/rescuing-an-interrupted-ubuntu-upgrade/ seems helpful but not adequate to resolve my package conflicts. Also there's a strange thing where the grub menu seems not to be properly interpreted, but eventually I get the splash screen with "/ is not ready yet or not present. Continue to wait; or press S to skip or M to recover manually." Manual recovery puts me in a single user shell where I can easily remount / as rw and bring up the network. If I become myself, the command line seems quite robust, but, there seems to be no way to get X11 going.

• Using JQuery to set create a flexible 3 column layout with Divs

  - by Chris Hammond

  This evening I was working on creating a Full Width skin for http://www.sccaforums.com/ , the current skin is at a fixed width, which doesn’t work very well for an active Forum when you have a browser with a high resolution. (The site runs on DotNetNuke , so this post will feature examples for DotNetNuke, but the code is applicable to any HTML pages) Basically I wanted a three column layout, and depending on if there was content in the Left and Right columns, I wanted them to not display at all,...(read more)

• Can anyone do anything about the spam here on weblogs.asp.net?

  - by Chris Hammond

  If there anyone out there who can do something about the spam here on weblogs.asp.net? Perhaps we could get some new software here that we could use to blog with? The old software barely works in Chrome (I can't see the rich text editor at this point), and lately the notification emails for Comments (which are mostly spam anyways) are pointing to http://weblogs.aspnet05.orcsweb.com which tries to get you to login with https://weblogs.aspnet05.orcsweb.com/ Anyone still maintaining this place?...(read more)

• Updating your DotNetNuke Copyright Statement for 2011, and beyond

  - by Chris Hammond

  originally posted on my DotNetNuke.com blog Every January people start thinking “oh crap, I need to update the copyright statement on my website”. And everyone runs out and makes the change to the current year. Well, if you use DotNetNuke you can easily change the Copyright statement on your site from the Site Settings page, found under the Admin menu. You’ll find a setting like the following. If your Skin in DotNetNuke uses the Copyright SkinObject then changing that setting and updating the settings...(read more)

• New free DotNetNuke 7.0 Skin

  - by Chris Hammond

  With the pending release of DotNetNuke 7, scheduled for this week, I updated my free DotNetNuke (DNN) skin , MultiFunction v1.3 . This latest release requires DotNetNuke 7, it shouldn’t install on an earlier version of DNN. This release updates a number of the CSS classes for DNN 7 specific styles and objects. Overall the design of the skin doesn’t really change much, just cleans up CSS mainly for this release. I also updated to the 3.0 version of the Orangebox jQuery plugin, you can find the code...(read more)

• DotNetNuke is switching to C#, uh oh

  - by Chris Hammond

  If you didn’t see Shaun’s blog post earlier this week you should give it a good read through . The post announced the fact that starting with Version 6.0 (targeted for Q2 2011) DotNetNuke will no longer be developed/released as a VB.NET Application. All development of the core platform will be in C# (this does not mean that the community modules for the platform will change languages). Most of the feedback I have seen so far has been rather positive, most folks who use DotNetNuke on a regular basis...(read more)

• Using jQuery to customize the styles in table cells

  - by Chris Hammond

  Originally posted on ChrisHammond.com I was trying to do some work with the Form and List module in DotNetNuke today and I needed to apply some custom styles to the LIST view of a module, without going in and creating a full XSL template for the module to use, I wanted to style the default table based grid view. In order to customize this view though I needed to do some custom jQuery that runs after the table is loaded, the jQuery then goes through and looks for columns, and based on the number of...(read more)

• Loadbalance UDP traffic with session affinity and way to take servers in & out of rotation

  - by William

  What is the best way to go about load balancing UDP traffic among a whole bunch of servers, while keeping session affinity based on the users' IP? I need to also be able to take servers in and out of rotation for new clients, so when they join for the first time, they get put on a server in a list of available servers, and clients already connected would stay connected to their specific server. I have written the software to maintain a list, but I can't seem to find anything that would perform this functionality. If you need the context, this is to facilitate game tournaments for Minecraft: Pocket Edition, which is done with UDP traffic, I cannot change the protocol. And, because tournaments open and close, I need to be able to place players on their proper servers. Performance is also a priority, I have a program to do this but it is very bloated and slow. Thanks for any help! William

• Architecture: Bringing Value to the Table

  - by Bob Rhubart

  A recent TechTarget article features an interview with Business Architecture expert William Ulrich (Take a business-driven approach to application modernization ). In that article Ulrich offers this advice: "Moving from one technical architecture might be perfectly viable on a project by project basis, but when you're looking at the big picture and you want to really understand how to drive business value so that the business is pushing money into IT instead of IT pulling money back, you have to understand the business architecture. When we do that we're going to really be able to start bringing value to the table." In many respects that big picture view is what software architecture is all about. As an architect, your technical skills must be top-notch. But if you don't apply that technical knowledge within the larger context of moving the business forward, what are you accomplishing? If you're interested in more insight from William Ulrich, you can listen to the ArchBeat Podcast interview he did last year, in which he and co-author Neal McWhorter talked about their book, Business Architecture: The Art and Practice of Business Transformation.

• How to retrieve only updated/new records since the last query in SQL?

  - by William Choi

  Hi all, I was asked to design a class for caching SQL query results. Calling the class' query method will query and cache the entire set of results at the first time; afterward, each subsequence query will retrieve only the updated portion, and will merge the result into the cache. If the class is required to be generic, i.e. NO knowledge about the db and the tables, do you have any idea? Is it possible, and how to retrieve only updated/new records since the last query? Thanks! William
