Reach Out, Touch Me

I just saw a question on life hacker about why you would want a touch screen PC. The thing I found interesting is the talk of ‘Gorilla arm’ whereby your arm gets fatigued because of having to be in an unnatural position for long periods. There are studies done on this topic such as ‘Human arm stiffness characteristics during the maintenance of posture’ and ‘Dynamic and loaded impedance components in the maintenance of Human Arm Posture’.

The biggest thing you have to remember is

  • Ergonomics are important whether you’re using a laptop, desktop, mobile or tablet
  • As a developer you should imprint ergonomics into your daily routine. Reduce your stress, stay healthy, alternate between a standing and seated desk and most importantly, be considerate to your poor wrists.
  • If you’re not a developer, but still use technology, learn about the best ergonomical positions for that device. Then teach your family, kids especially about this. The sooner you teach them and imprint upon them the importance of ergonomics, the better it will be for them in the long run by reducing injuries.

There are numerous studies done on tablet size and usage position:

The image above shows just how complicated ergonomics is from a business perspective. Getting businesses to change their approach to ergonomics is a slow process and neither you or I have the time to pursue such a goal. Take matters into your own hands. After all this is your health and your life. So what can you do?

Companies have been creating ergonomic products to use with computers for a while. Ergotron is probably the best known manufacturer of single and multiple monitor arms.

See LifeHackers post on Ergonomics for more info. Here are some noteworthy posts.

If you do one thing this year, invest in your health. We need you. (NOTE TO SELF: EXERCISE YOU LAZY SOD!)

Using Tincr with ASP.NET MVC in Windows 7

If you’re not aware, tin.cr is an extension to Chrome that allows you to edit your JavaScript and CSS files in Chrome or using your editor of choice and affecting the source and destination. I personally wanted to use it to make modifications to JavaScript files in VS2012 and have Chrome auto load the file and put it into effect on the page. Thus I save myself numerous page refreshes while I work out kinks. Tincr was developed by Ryan Ackley. Here is the official video for Tincr.

Installing Tincr on Windows 7

  1. Visit the tin.cr website.
  2. Click on the Download Tincr button (Do this through chrome and it will take you to the chrome extension install page).image
  3. Once you have added the extension restart the browser and you should see a Tincr tab in the Developer Tools windowimage<

Setup Tincr

  1. We now need to create a tincr.json file. Open up your favorite editor and post the following code into it (remember to change MyApp to your app name):

        “toFile” : [],
        “fromFile” :
                “from”: “\\\\Scripts\\\\([a-zA-Z]+)\\.js”,
                “to”: “/MyApp/Scripts/$1.js”

    This tincr.json file tells tincr to look for JavaScript files in the Scripts folder and apply that to the ‘to’ URL. Notice it is using regex so if you have funky named files, you will have to change the regex. In my case, the js file is called ‘common.js’. Once you are done, save the tincr.json file to the root directory. This will be the location of the ASP.NET MVC app directory that is hosted in IIS. In my case, it was C:\dev\tfs\MyApp.

  2. Now you need to setup Tincr. You can mimic the options I set here. For Root Directory, you should point to the location of the ASP.NET MVC app directory that is hosted in IIS. In my case, it was c:\dev\tfs\MyApp. You should see the green ‘Project loaded successfully’ before you begin to use this.image

Using Tincr

  1. We are ready to test this out. Open a browser window and navigate to the URL. In my case it is http://localhost/MyApp. Now go into VS2012 and make a change to a JavaScript file. You should see a message in Dev Tools Console saying “Auto-Reloaded http://localhost/MyApp/Scripts/common.js”. In the case below, I had a console.log(‘asdf’) that I changed to ‘its alive’ in a jquery function that did something on hover. So I just saved the file in VS 2012, moved my mouse over the element and saw the new message. AWESOME!image

Issues with Tincr

If you don’t see the Auto-Reloaded message, it means that your tincr.json file is incorrect OR the extension is not able to figure out your file. This is something that I struggled with for a little bit.

  • The Extension has an issue with windows where query string parameters affixed to the JavaScript URL will make it fail.
  • Another possible issue is if you have an AJAX request that downloads a JavaScript file because it’s a link in the content that was returned. Well, your URL for that JavaScript file may have been altered by JQuery. Use Fiddler and make sure that your URL for the file does not contain any query parameters. It will save you a bunch of time.

Happy Coding.
