Teaching with Video

The whole post...

The 30-Second Summary

  • Know your audience: Learn what your audience struggles with and what they want to know more about and use it to inform your script. Set context around your video by mentioning clear prerequisites.
  • Keep it concise: Cut the fluff from your videos to keep the length manageable, and break down long content into digestible chunks so that viewers can self-navigate.
  • Planning matters: Spec out your video specifically for the online format, and prepare a script before shooting.
  • Quality is essential: You don't have to spend thousands of dollars on equipment, but good audio and a decent lo-fi studio setup with a backdrop can make your production feel much more professional.
  • Look at metrics that tie to your goals: Specific measurements like student projects can speak to the effectiveness of your teaching on an entirely different level than general analytics.
  • Good supplementary content: Supplementary materials, like quizzes, transcripts, ebooks, and PDFs, can be a differentiator for your course and help tailor to different learning styles.
  • Passionate instructors: Put someone who's actually an expert on screen, rather than hiring an actor.

Using Table as layout in HTML 5

The HTML5 specification still recommends that you don't use tables for layout, but if you do, you should differentiate those tables from tables that are used for tabular data.

Features to Define Your Table as Layout or Non-Layout

Feature of Table Is a Layout Table?
<table role="presentation"> It probably is a layout table
<table border="0"> It probably is a layout table
<table cellpadding="0"> It probably is a layout table
<table cellspacing="0"> It probably is a layout table
Use of the CAPTION, THEAD, or TH elements It probably is not a layout table
Use of the headers and scope attributes on the TH element It probably is not a layout table
<table border=""> It probably is not a layout table
<table border="1"> It probably is not a layout table

Loss

A man once went to a minister for counseling.

“I’ve lost everything” he bemoaned.
“Oh,” the preacher responded, “I’m so sorry to hear you’ve lost your faith.”
“No,” the man corrected him, “I haven’t lost my faith.”
“Well then,” replied the preacher, “I’m sad to hear you’ve lost your character.”
“I didn’t say that,” the man corrected.  “I still have my character.”
“Then I’m so sorry to hear you’ve lost your salvation.”
“That’s not what I said!” the man objected, beginning to lose patience.
The minister explained, “Well, you have your faith, your character, and your salvation.  Seems to me, you have lost none of the things that really matter.”

Detach a Process in Visual Studio and IE 10 javascript debug

Having an error after installing IE 10:
Attaching the Script debugger to process '[<ID>]' iexplore.exe' on machine '<computer name>' failed.  A debugger is already attached.

To detach this process:
  • Open the Processes windows (Debug, Windows, Processes)
  • Select the process (iexplore.exe with that ID), right click and select "Detach Process"

To fix the problem without detaching the process every time:
  • run the following in a command window: regsvr32.exe "%ProgramFiles(x86)%\Common Files\Microsoft Shared\VS7Debug\msdbg2.dll"
  • make sure run the cmd prompt as an administrator

FireFox 18.0.1 stops working

First posted on Feb 2, 2013
I am not able to start FireFox after installing the latest version of Nvidia driver.  I can start in safe mode.  It is strange that I can start the winPenPack version of the X-FireFox (18.0.1).

I have tried to disalbe all the add-ons and plugins, this didn't work.

Solution
After I do a "clean" installation of an older version (301.42) of the video driver, finally, I can start FireFox again.

Update:
I forgot this problem and upgrade to 314.22, the problem is back...

New Solution
In safe mode, go to  Options, Advanced, General and uncheck the "Use hardware acceleration when possible."

Install NuGet package manually

I accidentally (without checking the description) installed a new version of a package which is not compatible to the project and I cannot find the correct version from the NuGet Installer anymore.  I have a test project which contain the package.  Since I cannot install the package from the UI, I need to install it manually.

Open the Pack Manager Console (View, Other Windows) and type the following:
  • Install-Package <package name> -Source C:\Projects\<project name>\packages\
The package name will be the first part of the folder name before the version number.  For example, the package folder name is "MvcMailer.4.0" and the package name is "MvcMailer".

Web Application targets IE 9 and above...

Add this to the master page or the shard layout file, and IE will not go into the compatibility mode (IE 8)
  • <meta http-equiv="X-UA-Compatible" content="IE=9" />

LINQ Zip and join

Add two list sequentially together according to it order... stop when end of one list.

Fast but limited compare with join.

(roleList).Zip(roleDescriptionList, (r, rd) => new RoleDescription() { roleID = r.dataID, role = r.dataValue, description = rd.dataValue }).ToList();

roleList and roleDescriptionList are two separate lists.  They can be unrelated at all.
Using Zip() to join them together to create a new list of object "RoleDescription" one by one.

To have better control, you should use join instead.


IList<RoleDescription> result = (from r in roleList
                         join rd in roleDescriptionList
                         on r.dataID equals rd.dataID
                         select new RoleDescription { 
                             roleID = r.dataID, 
                             role = r.dataValue, 
                             description = rd.dataValue }).ToList();

MVC Partial View

When having <script></script> in a partial view, remember don't use the @section Scripts {
} since the partial view has no Layout (i.e. you have this @{ Layout = null} on the top of the partial view.

MVC StringLength and maxlength

When you add the validation StringLength in MVC, it won't automatically limit the user to the max length.  You need to manually to add this in the View.

You cannot use @Html.EditorFor and you should use @Html.TextBoxFor.


<%=Html.TextBox("polNum",null, new {maxlength=10}) %>

@Html.TextBoxFor(model => model.homePostalCode, new { maxlength = 7 })

jQuery UI Dailog, IE and DropDownList

There is a problem to select from a dropdownlist in a jQuery Dialog plug-in.  It happens only in IE (8 and 9, at least).  It works in FireFox.

  • The very first time (after opening the dialog) will work but it won't when I try to select another value
  • I can select the value using the keyboard
  • Tab to the dropdownlist and select with the mouse
  • I tired to add the z-index to the dropdownlist but it doesn't help
Solution:
  • The current solution is adding a mouseover event to set the focus to the dropdownlist.
onmouseover = "this.focus();return true;"

jQuery Template

pass a string:
$.tmpl("<div class="myClass">${FirstName},/div>", myObject).appendTo("#myDiv");

use a selector to find a script block on the page:
$("#myTemplate").tmpl(myObjects).appendTo("#myDiv");

...

<script id="myTemplate" type="text/x-jquery-tmpl">
    <tr>
        <td>${FirstName},/td>
        <td>${LastName},/td>
        <td>${Twitter},/td>
    </tr>
</script>

get an external "html" which contain the html template:

$.get("MyTemplate.htm", function (data) {
    $.tmpl(data, myObjects).appendTo("#myDiv");
});

jQuery General Performance Tips


  • use the latest jQuery
  • Caching Selections (assign it to a variable) 
  • Caching Other Items
  • Use element properties (DOM) when possible (instead of jQuery properties)

  • $.isEmptyObject(object)
  • $.isPlainObject(object)
  • $.isXmlDoc(doc)
  • $.isNumeric(number)
  • $.isWindow(window)
  • $.type(object)

 Return Values:
  • boolean
  • number
  • string
  • function

Turn javascript object into a string

use json2.js from http://www.JSON.org/json2.js

e.g.
<script src="json2.js"></script>
...
JSON.stringify( {
    FirstName: $('#FirstName').val(),
    LastName: $('#LastName').val()
});

To turn a JSON string into javascript ojbect, use parseJSON.

var json = '{"fname" : "john", "lname" : "smith", "age" : 35}';
var jsObject = $.parseJSON(json);

WCF returning Json data

in the .net world, we need to get the data by getting the property d like this:

var cust = data.d[0];

var cust = data.d.firstname;

this won't work: var cust = data[0];

MVC - Sending Email using Exchange Server

Add the following in the Web.config file:

<system.net>
  <mailSettings>

    <smtp from="info@mycompany.com">
<network enableSsl="false" port="25" host="mail.mycompany.com" defaultCredentials="true" />
    </smtp>


  </mailSettings>


</system.net>

Without setting "defaultCredentials" to true, you can only send email in the same domain.  When you send email outside the domain, you will receive "Mailbox unavailable. The server response was: 5.7.1 Unable to relay for whoever@notmycompany.com" error.

C# HashSet

A HashSet holds a set of objects, in a way that it allows you to easily and quickly determine whether an object is already in the set or not.

C# HashSet class preserves the order of the elements.

The only catch of HashSet is that there is no access by indices.
