via Hacker News - Some Sitepoint Article: How not to Critique a Javascript Library

Terrible nit-picking blow-hard article documented here http://www.reddit.com/r/programming/comments/a3i4w/google_closure_how_not_to_write_javascript/

(I will not link to the original trashy article.)

The Google Closure library [ one part of the Google Closure project http://code.google.com/closure/ ] is not bad, and will only get better. Both the Closure library and the jQuery library will grow and improve in the brave new future of first rate JavaScript compilers in web browsers

Hacker News | Some Sitepoint Article: How not to Critique a Javascript Library:

Really? You tested it? Because a 'switch' does not necessarily generate the same code as a dynamically constructed set of object properties. In Google's original example, if none of the cases match, it immediately returns 'true'. In Sitepoint's example, if the property does not match on the highest level, it must crawl the property chain on the object until it eventually reaches 'undefined'. Not to mention you are making two inner function calls and a fully dynamic property lookup (!(), hasOwnProperty, and node.tagName), none of which I believe can be calculated statically. Actually, I'm going to end this rant early, because I just read more of the article, and it looks like the author just keeps pulling random shit that he remembers reading from 'Javascript: The Good Parts' or whatever and vomiting it back up onto his keyboard.

Also, the original article has no time tests under V8 [ http://code.google.com/p/v8/ ] after passing through the Google Closure compiler. Or any time tests at all. Pathetic. Shame on Kevin Yank and Dmitry Baranovskiy.

Jason Calacanis on How To Kill Google

Image by John Niedermeyer via Flickr

I am a fan of Google, but I would love to see the top five mainstream-media sites be exclusively indexed by Bing. It would be a real-world test of how effectively Google is able to monetize search compared to Microsoft/Yahoo. Right now we can only guess. If this really took place, bloggers would be the big winners, because they would leap to the top of the searches. Anyone who thinks there is better reporting in the mainstream media just hasn't read the top bloggers in their particular area of expertise and interest. Mainstream reporters have to pull their punches.

See [Secret Diary of Steve Jobs]: "Why the mainstream media is dying"

http://www.fakesteve.net/2009/11/why-mainstream-media-is-dying.html

The best reporters of the top five mainstream media sites would have a reason to move to Huffington Post, if Google can raise Huffington Posts hits, if Google can effectively monetize those hits, and if Huffington Post's business model allows more money to flow to the people actually writing the stories.

I would love to see it all play out - to see what would really happen.

Adding Google's google-code-prettify to Blogger

Image by palewire via Flickr

Wanted to be able to add highlighted code snippets, so copied how Python's Guido does it (nice example), as a stop-gap.

Blogger's support for programming code is embarrassing; zero-support given. So this is at best a partial fix. It makes use of Google's own google-code-prettify Javascript code. It is easy to use, so the whole of the docs fits easily on a single page:

http://google-code-prettify.googlecode.com/svn/trunk/README.html

Using "Blogger Control Panel | Layout | Edit HTML": just inside the "<head>" block, add these CSS and Javascript links:

<link
href='http://google-code-prettify.googlecode.com/svn/trunk/src/prettify.css'
rel='stylesheet' type='text/css'/>
<script
src='http://google-code-prettify.googlecode.com/svn/trunk/src/prettify.js'
type='text/javascript'></script>

Then add "onload='prettyPrint()'" to the opening "<body>" tag

<body onload='prettyPrint()'>

You will need to use HTML escape if the code had naughty HTML syntax characters (&,",',>,<). A good writeup: http://wiki.python.org/moin/EscapingHtml. [Don't be confused like I was: this is different functionality than the xml.sax.saxutils function quoteattr !]. You can also use an online HTML escape tool like htmlescape.net.

Then put whatever code you wish between these HTML brackets

<pre class="prettyprint"> ... </pre>

Here is a tiny snippet of Python highlighted code:

def hello(i):
print "hello"
print i

For a whitespace sensitive language like Python, it pays to take a little caution, to compensate for the typical laxness of whitespace preservation in HTML and Blogger's basic editing tools. Type or cut-and-paste the code in the "Edit Html" tab - you will get good and predictable results.

In general, when using Blogger's in browser WYSIWYG editing tools, check the "Edit Html" tab last, just to make sure that Blogger's editing tools did not strip extra spaces from your Python code
