• Part 4, Getting the conversion tables ready for CS to DNN

  - by Chris Hammond

  This is the fourth post in a series of blog posts about converting from CommunityServer to DotNetNuke. A brief background: I had a number of websites running on CommunityServer 2.1, I decided it was finally time to ditch CommunityServer due to the change in their licensing model and pricing that made it not good for the small guy. This series of blog posts is about how to convert your CommunityServer based sites to DotNetNuke . Previous Posts: Part 1: An Introduction Part 2: DotNetNuke Installation...(read more)

• DC Comics Identifies Krypton on the Star Map

  - by Jason Fitzpatrick

  This week Action Comics Superman #14 hits the stands and DC comics reveals the actual location of Kyrpton, delivered by none other than beloved astrophysicist Neil Tyson. Phil Plait at Bad Astronomy reports on the resolution of fans’ long standing curiosity about the location of Krypton: Well, that’s about to change. DC comics is releasing a new book this week – Action Comics Superman #14 – that finally reveals the answer to this stellar question. And they picked a special guest to reveal it: my old friend Neil Tyson. Actually, Neil did more than just appear in the comic: he was approached by DC to find a good star to fit the story. Red supergiants don’t work; they explode as supernovae when they are too young to have an advanced civilization rise on any orbiting planets. Red giants aren’t a great fit either; they can be old, but none is at the right distance to match the storyline. It would have to be a red dwarf: there are lots of them, they can be very old, and some are close enough to fit the plot. I won’t keep you in suspense: the star is LHS 2520, a red dwarf in the southern constellation of Corvus (at the center of the picture here). It’s an M3.5 dwarf, meaning it has about a quarter of the Sun’s mass, a third its diameter, roughly half the Sun’s temperature, and a luminosity of a mere 1% of our Sun’s. It’s only 27 light years away – very close on the scale of the galaxy – but such a dim bulb you need a telescope to see it at all (for any astronomers out there, the coordinates are RA: 12h 10m 5.77s, Dec: -15° 4m 17.9 s). 6 Ways Windows 8 Is More Secure Than Windows 7 HTG Explains: Why It’s Good That Your Computer’s RAM Is Full 10 Awesome Improvements For Desktop Users in Windows 8

• Keep website and webservices warm with zero coding

  - by oazabir

  If you want to keep your websites or webservices warm and save user from seeing the long warm up time after an application pool recycle, or IIS restart or new code deployment or even windows restart, you can use the tinyget command line tool, that comes with IIS Resource Kit, to hit the site and services and keep them warm. Here’s how: First get tinyget from here. Download and install the IIS 6.0 Resource Kit on some PC. Then copy the tinyget.exe from “c:\program files…\IIS 6.0 ResourceKit\Tools'\tinyget” to the server where your IIS 6.0 or IIS 7 is running. Then create a batch file that will hit the pages and webservices. Something like this: SET TINYGET=C:\Program Files (x86)\IIS Resources\TinyGet\tinyget.exe"%TINYGET%" -srv:dropthings.omaralzabir.com -uri:http://dropthings.omaralzabir.com/ -status:200"%TINYGET%" -srv:dropthings.omaralzabir.com -uri:http://dropthings.omaralzabir.com/WidgetService.asmx?WSDL - status:200 First I am hitting the homepage to keep the webpage warm. Then I am hitting the webservice URL with ?WSDL parameter, which allows ASP.NET to compile the service if not already compiled and walk through all the operations and reflect on them and thus loading all related DLLs into memory and reducing the warmup time when hit. Tinyget gets the servers name or IP in the –srv parameter and then the actual URI in the –uri. I have specified what’s the HTTP response code to expect in –status parameter. It ensures the site is alive and is returning http 200 code. Besides just warming up a site, you can do some load test on the site. Tinyget can run in multiple threads and run loops to hit some URL. You can literally blow up a site with commands like this: "%TINYGET%" -threads:30 -loop:100 -srv:google.com -uri:http://www.google.com/ -status:200 Tinyget is also pretty useful to run automated tests. You can record http posts in a text file and then use it to make http posts to some page. Then you can put matching clause to check for certain string in the output to ensure the correct response is given. Thus with some simple command line commands, you can warm up, do some transactions, validate the site is giving off correct response as well as run a load test to ensure the server performing well. Very cheap way to get a lot done.

• Cross-Platform Mobile Development With Mono for Android and MonoTouch

  - by Wallym

  Many years ago, in fact pre-Java, I remember a hallway discussion about the desire to write a single application that could easily run across various platforms. At the time, we were only worried about writing applications on Windows 3.1 and Mac OS 7.x. There were many discussions about windows, user interface concepts, and specifically a rather long discussion as to whether Mac users would accept a Mac application that didn't have balloon help. Thankfully, the marketplace answered this question for us with the Windows API winning the battle.A similar set of questions is currently going on in the mobile world. Unfortunately, at this point in time, there is currently no winning API and none currently in sight. What's a developer to do? Here are some questions that developers have (and there are many more):How can mobile developers target Android and the iPhone with the same code?How can .NET developers share their code across Android, iPhone and other platforms?How can developers give applications the look and feel of the specific platform and still allow as much code as possible to be shared?Mobile devices share many common features, such as cameras, accelerometers, and address books. How can we take advantage of them in a platform independent way and still give the users the look of every other application running on their platform?In this article, we'll look at some solutions to these cross-platform and code-sharing questions between Mono for Android, MonoTouch and the .NET Framework available to developers.

  Are you a frequent user of TinEye and would like to integrate it into your favorite Windows system? Then get ready to enjoy Context Menu and App Window goodness with the TinEye Client for Windows. After you have downloaded the zip file, unzip it and run the setup file inside. Once the installation process has finished you will be asked if you would like to launch TinEye Client immediately or not. If not then you can access it later using the new shortcut added to the Start Menu. We chose to let the program launch automatically…this is what the main window looks like. For our test we decided to access the client via the Context Menu using a picture of Doc Brown’s DeLorean in hover conversion mode.

• Square Reader Modified to Record Off Old Reel-to-Reel Tape [Video]

  - by Jason Fitzpatrick

  The Square Reader is a tiny magnetic credit card reader that has taken the mobile payment industry by storm. This clever hack dumps the credit card reading in favor of snagging the audio from old music reels. Evan Long was curious about whether the through-the-headphones interface of the Square Reader could be used to read audio data off old magnetic recordings. With a very small modification (he had to bend a metal tab inside the reader to allow the audio tape to slide through more easily) he was able to listen to and record audio off old reels.

• 50 Years of LEDs: An Interview with Inventor Nick Holonyak [Video]

  - by Jason Fitzpatrick

  The man who powered on the first LED half a century ago is still around to talk about it; read on to watch an interview with LED inventor Nick Holonyak. The most fascinating thing about Holonyak’s journey to the invention of the LED was that he started off trying to build a laser and ended up inventing a super efficient light source: Holonyak got his PhD in 1954. In 1957, after a year at Bell Labs and a two year stint in the Army, he joined GE’s research lab in Syracuse, New York. GE was already exploring semiconductor applications and building the forerunners of modern diodes called thyristors and rectifiers. At a GE lab in Schenectady, the scientist Robert Hall was trying to build the first diode laser. Hall, Holonyak and others noticed that semiconductors emit radiation, including visible light, when electricity flows through them. Holonyak and Hall were trying to “turn them on,” and channel, focus and multiply the light. Hall was the first to succeed. He built the world’s first semiconductor laser. Without it, there would be no CD and DVD players today. “Nobody knew how to turn the semiconductor into the laser,” Holonyak says. “We arrived at the answer before anyone else.” But Hall’s laser emitted only invisible, infrared light. Holonyak spent more time in his lab, testing, cutting and polishing his hand-made semiconducting alloys. In the fall of 1962, he got first light. “People thought that alloys were rough and turgid and lumpy,” he says. “We knew damn well what happened and that we had a very powerful way of converting electrical current directly into light. We had the ultimate lamp.” How To Get a Better Wireless Signal and Reduce Wireless Network Interference How To Troubleshoot Internet Connection Problems 7 Ways To Free Up Hard Disk Space On Windows

• CRM Magazine: Customer-Facing Life Sciences CRM

  - by charles.knapp

  "The Life Sciences Edition, Lye says, is unique in that to-date pharma software has been inward facing. The Oracle pharma solution, however, is a tool that can be used internally for salespeople to assess their effectiveness, but it can also be used in interacting with a physician or whoever the "customer" might be. The solution captures signatures digitally and provides tools for rapid presentation creation. "That's something I have never heard of before in terms of having the CRM product for the customer view as well as the employee view," Leary says. "When it comes to the area of pharma sales, [sales people] don't have a lot of time in front of doctors .... so this is a way to spend less time in front of the doctor and still be able to get the information and the sentiment and the story across."
