PowerShell “fun” with text to speech

Writing code can be rather far from glamorous if not downright boring sometimes. PowerShell has its appeal but it is at the end of the day still an administrative framework for task and configuration automation.  Even saying that can hurt… If you’re looking to spice it up a bit the following may help.

function prompt { $text = ‘You are great!’, ‘Hero!’, ‘What a checker you are.’, ‘Champ, well done!’, ‘Man, you are good!’, ‘Guru stuff I would say.’, ‘You are magic!’    ‘PS> ‘    $host.UI.RawUI.WindowTitle = Get-Location    (New-Object -ComObject Sapi.SpVoice).Speak(($text | Get-Random)) }

JS Library For Image & Vector-Tiled Maps

Polymaps is a free JavaScript library for making dynamic, interactive maps in modern web browsers.

Polymaps provides speedy display of multi-zoom datasets over maps, and supports a variety of visual presentations for tiled vector data, in addition to the usual cartography from OpenStreetMap, CloudMade, Bing, and other providers of image-based web maps.

“Because Polymaps can load data at a full range of scales, it’s ideal for showing information from country level on down to states, cities, neighborhoods, and individual streets.

Because Polymaps uses SVG (Scalable Vector Graphics) to display information, you can use familiar, comfortable CSS rules to define the design of your data.

And because Polymaps uses the well known spherical mercator tile format for its imagery and its data, publishing information is a snap.”

Javascript transition effects with Blockster

Highlighting your featured content can be quite the challenge. Getting the aesthetics right by pulling the eye in without stabbing it is a valuable skill. A nice tool that you can use when appropriate is Blockster.

Blockster is a Javascript transition effect designed for ‘featured content’ rotators or slideshows. Its underlying concept is to transition between one element to the next block by block. It is highly customisable in terms of how many blocks are involved, whether they fade in or simply appear, whether they appear in order or randomly, and more.

The script gives you full control over how the script behaves, giving you scope to create some pretty varying effects. You can set the number of rows and cols in the block grid, whether the blocks should fade in or simply appear, whether they should appear randomly, in order, etc.

Getting started with HTML5: Three steps

Even though it is unfinished standard you can and should get started with HTML5 and it is more easy than you may think…

The new Doctype
Is as easy as it can get. Just replace
< !DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
< html xmlns="http://www.w3.org/1999/xhtml">


 with
< !DOCTYPE html>
< html>
and you’re done. Simple.

Video
The format wars are being fought rather publicly these days and the best  part is that it should have little to no effect on you. The < video> tag is able to hold more than one SRC. So your browser can roll down through the options until it finds what will work. Again, simple. The best place to learn more is here: http://camendesign.com/code/video_for_everybody where they have loads of samples such as:

< !– Video for Everybody, Kroc Camen of Camen Design –>
< video width=”640″ height=”360″ controls preload=”none”>
< source src=”__VIDEO__.MP4″  type=”video/mp4″ />
< source src=”__VIDEO__.OGV”  type=”video/ogg” />
< object width=”640″ height=”384″ type=”application/x-shockwave-flash” data=”__FLASH__.SWF”>
< param name=”movie” value=”__FLASH__.SWF” />
< param name=”flashvars” value=”image=__POSTER__.JPG&file=__VIDEO__.MP4″ />
< img src=”__VIDEO__.JPG” width=”640″ height=”360″ alt=”__TITLE__”
    title=”No video playback capabilities, please download the video below” />
< /object>
< /video>
< p> < strong>Download Video:
Closed Format: < a href=”__VIDEO__.MP4″>”MP4″
Open Format: < a href=”__VIDEO__.OGV”>”OGG”
< /p>

Next up, smarter forms.
Weary of validating if that really is an email address or proper URL in that field? Well now the effort is in the lap of the browser. Again, they are really easy to implement. Examples would be

Email: < input type=”email”>
URL: < input type=”url”>
Number: < input type=”number”>
Phone: < input type=”tel”>
Color picker: < input type=”color”>

Slider: < input type=”range” min=”0″ max=”10″ step=”2″ value=”5″>
etc.

Simple, no? Failure is graceful too as the fall back is to text.

Placeholder text for any of these is just as easy!

< input type=”email” placeholder=”Your email address”>

And again, the browser does the work by responding to the cursor by clearing the field automatically. 

And even better! If you need to make it a required field just add “required.”

< input type=”email” placeholder=”Your email address” required>

What if your requirements are not listed? You can build / define your own. For example if you need a credit card field – which would consist of a string of numbers ranging from 13 to 16. Your field would contain this:

 pattern=”[0-9]{13,16}”>

Needless to say there is an awful lot more such as the canvas tag and all of its potential badness and goodness but this should get you started! If you are interested in the Canvas tag there is a good cheat sheet here: http://blog.nihilogic.dk/2009/02/html5-canvas-cheat-sheet.html

Data Visualization: The Quest for Patterns

Recently I was trying to present a way for individuals to find patterns in large amounts of data. The end result was considered successful and I thought I would share at a high level what was done.

Firstly, the data looked a tad liked this…

Note 1: this is NOT the actual data.
Note 2: C1 and C2 are where I wish to draw interest to in this example. I.e. the final outcome should be a clean visual of the all data with an intuitive focus where C1 and C2 get and send their data.

Certainly not terribly daunting, interesting, nor unfamiliar for the average office/information worker/victim 🙂
Running this through Excel Services really did not produce anything useful. It hinted at associations between the data points but that was it. See for yourself…

Not the best presentation of data I’m sure you’d agree… (Even forgiving the quality of the image.)
So I ran the data around a different set of axis with a bit of custom code and got a dramatically clearer view of the columns and their content associations. At least I think it is.

Colour coding C1 and C2 made things even more clear.

A successful solution!

Moving large numbers of records with SqlBulkCopy

Sometimes you have to move large amounts of data in, out, or around SQL. There are plenty of ways to do that but few are as fast as using SqlBulkCopy. It is not fast. It is blazingly fast. As with anything else it has its place and limitations but it is well worth understanding at the least.
It is pretty easy to work with as the below example shows…
static void CopyData(DataTable sourceTable, SqlConnection destConnection)
{
// new method: SQLBulkCopy:
using (SqlBulkCopy s = new SqlBulkCopy(destConnection))
{
s.DestinationTableName = “SalesCopy”;
s.NotifyAfter = 10000;
s.SqlRowsCopied += new SqlRowsCopiedEventHandler(s_SqlRowsCopied);
s.WriteToServer(sourceTable);
s.Close();
}
}

When used properly it can make seemingly large data volume transactions trivial.

The Microsoft SharePoint 2010 Software Development Kit (SDK) includes documentation and code samples for Microsoft SharePoint Foundation 2010 and for Microsoft SharePoint Server 2010, which builds upon the SharePoint Foundation 2010 infrastructure. The documentation includes detailed descriptions of the technologies that SharePoint Server 2010 and SharePoint Foundation 2010 provide for developers, reference documentation for the server and client object models, and step-by-step procedures for using these technologies and object models and programming with them.

This SDK also includes best practices and setup guidance to help you get started with your own custom applications that build and extend upon the SharePoint Foundation 2010 and SharePoint Server 2010 platforms.

UI Dragging : Dragdealer JS

Dragdealer is a drag-based JavaScript component that embraces endless front-end solutions. Elegantly crafted for JavaScript-aware coders.

The script is pretty flexible with options like:

  • working horizontally or vertically
  • defining the initial positions of the slider (x/y)
  • setting the number of steps for the slider
  • snapping to the steps
  • and much more.

Dragdelaer JS has callbacks on both release and move events which makes any type of interactions possible.

Speed up your PHP like Facebook does with HipHop for PHP

It’s a fact that script based languages and frameworks slow you down. PHP and its huge amount of frameworks is no exception to that rule. Until you realize that it is used on the busiest site out there – Facebook.
Scripted languages typically are embraced as they have advantages in being simple to learn, code, and debug while counterbalanced with a definite sacrificing of speed. On the other side of the spectrum, compiled languages usually have a steeper learning curve and are much more strict; counter balanced with the clear fact that they are considerably faster and better optimized for handling memory. Facebook seems to have found a balance between both worlds with HipHop for PHP.
Facebook developers write lots of their core services in other languages, and then PHP is used as the glue that queries those services and builds the actual pages itself. Still, they have found that that really isn’t fast enough for what they want, so they went and wrote their own compiler, or rather an optimizer, called HipHop, which compiles PHP down to C++ which can then be compiled by G++.
You can download HipHop from here: http://github.com/facebook/hiphop-php

If you’re interested in using/trying some PHP frameworks you can start by looking at:

After The Deadline is a project of Automattic (the creator of WordPress) which checks:

  • spelling
  • grammar
  • styles (finds complex phrases, cliches, bias-language & suggests simple ones)
  • and detects misused words (has a database of 1500 most misused words & suggestions)

The software used to come as a plugin for several projects (like WordPress, RoundCube, PHP List) but it is now open source and anybody can embed it to their own code.

Besides the artificial intelligence it already has, it is possible to add new rules & improve the application.

The project also has libraries for jQuery, Ruby & Python to make developing new plugins easier.
