It occurred to me that if I am to work for a web firm I should really know some web technology. My knowledge of the web was extremely out-of-date and patchy, so I thought it time to make it up-to-date and patchy. The aim wasn't to learn all the latest trendy technologies, but more what's been the backbone for a while.
The web used to be a horrible mess, but with the triumvirate HTML5, CSS and Javscript, plus modern browsers, things are a lot neater and more pleasant. To learn, I did a pile of courses on codecademy. This was rather neat as I didn't only learn a bit of modern HTML, CSS and JS, but I also got pointed at Boostrap and jQuery. I guess you can say technology is mature when it's got helper libraries on top of it! I understood the existence of JS helpers, but CSS helpers were a bit of a surprise.
Anyway, the existence of these libraries explained something of a mystery to me: Why so many websites have such similarity in style, beyond the demands of fashion. Well, they're all using the same libraries. Also, I got to find out that the basic use of jQuery is not to do with querying, but for putting animations and effects on your web pages.
It also reminds me how conventional web pages are looking now. I remember "The web is a new medium! The old rules don't apply!". And now, the web looks like magazines. Ho hum. Anyway, my website's been updated to look like all the others, using the same libraries as everyone else. It's good practice, right?
Finally, I picked up AngularJS. I must admit, I feel somewhat ambivalent about it. For dynamic data, you've got to do things on the client-side. However, it seems to go a bit far - the codecademy tutorials encourage you to do things on the client-side that could have been done on the server-side. This seems inefficient and an unpleasant move away from the underlying document-centric view of the web. On the other hand, it's good for creating dynamic sites quickly and flexibly, without having to build server-side and client-side frameworks in tandem.
I can see this kind of mindset leading to painful mobile apps. As you can make a fairly fully-featured UI in a web browser, complete with JS implementation, why not just use that for the backbone of your app? Unfortunately, mobile phones don't have the spec of desktops. Well... I guess Moore's law is going to sort my objection out sooner or later, and you can have pretty and fast apps on your phone, at the expense of battery life.
Mostly, though, I can see the use in Angular. With modern hardware and the kind of web apps people are developing, efficient technology is beaten by RAD technology 95% of the time.
