Yes, it is true.
Take Reuters.com for instance:
total javascript = 414 KB
total image = 264 KB
|
|
|
|

Is their javascript transmitted uncompressed?? 414k gzipped is probably ~80k over the wire, so somewhat smaller than the images. Still a lot though.

Not to mention the majority of JavaScript can be downloaded once and used on multiple pages.

Maybe jquery, but not the rest. Um, you could even look at the page I mention and see for yourself, rather than making false assumptions. Look at http://www.webpagetest.org/[^]
while your at it and see how having dozens of javascripts slows down the page loading

I just looked at the page using the FireBug Net panel. I sorted the JavaScript from largest to smallest. Here are the largest JavaScript files:
- Facebook Widgets
- jQuery
- Twitter Widget
- Google Analytics
- yahoo-dom-event.js
Those are all third-party reusable libraries, and they are the bulk of the JavaScript. The majority of the other files appear to either be for reusable widgets (e.g., ticker, navigation, stocks) or mini libraries (e.g., geolocation, connection, cookie handling, animation, events, dom manipulation) that can be shared across pages.
Yes, I did make assumptions, but yes, they were correct.
By the way, merely having that many JavaScript files can slow down page load time, regardless of their file size, as browsers tend to download JavaScript files before downloading other files, and the latency alone increases the download time (browsers usually only allow about 5 concurrent downloads from a single domain). The solution to this is to host JavaScript files on a CDN with multiple domains to download from. This reduces the latency and allows the browser to download many of the JavaScript files simultaneously.

Yes, exactly. Therefore, you have to agree that the graphic designer isn't the only one responsible for the bloat

What is the chance of anyone having to move from C++ to Obj-C unless they are moving onto iOS specific development? Considering the fact that generic applications written in C++ can be ported to Mac.

If you want to access OSX/iOS APIs then you have to use obj-c

You'll need Objective-C for both Cocoa (Mac) and Cocoa Touch (iOS). Though you are right that C++ code can be compiled to run on Mac in many instances. But for native Mac/iOS programming most of it is done in Obj-C these days.
See also Xcode, GCC, and Homebrew[^] for some new ways to code without relying so heavily on Xcode.

In defense of doing it the “hard way” (source: accidental/ninja)
Learning to code is not the same as learning to write applications.

The method that’s worked best for me, and that I recommend to anyone starting out, is to try to build something that you want to see made as your first project.
When I started out, programming for Atari ST, I asked other people what they wanted to see. I got good ideas, good feedback, and a loyal customer base (until Atari started to unravel and I got out of there as quick as I could).
Other than that, I think the blog is spot-on.
