Udemy - Learn HTML5 from scratch

I've heard about HTML5 - but didn't really know what it was. So this sounded like a good course to find out.

Its fairly gentle as courses go, and all parts are explained well with all code written from scratch in front of you. It shows you how to do regular HTML first, before moving onto some of the advanced features.

So it starts with basic HTML together with inline styles, tables and input actions.

Then it moves onto CSS files and tailoring the result to look like what is required. It's quite fun to see the website evolving in front of you as you tweak padding, colors and so on.

Then it's on to HMTL5 new things. New tags, new form elements and so on. This is followed by graphics, video, geolocation, SVG graphics, mobile apps, caching and storage extensions. 

Its a very good overview, but you obviously need to know quite a lot of javascript (which isn't explicitly covered) to make good use of some of the new features.

Udemy - Introduction to Java Programming

So I was doing a bit of Android programming - writing apps and stuff.
I'd played around a bit with java when it first came out, but never written much in it. It's moved on a bit since then, so I thought I might catch up with it using this course.

I'd recommend the course for anyone who wants to learn Java. It's done at a nice slow pace, with lots of examples and takes you through each challenge showing how they would write the answer. This is always good - because normally people skip over the boring bits and head for the answer, missing out a couple of steps that you just can't seem to repeat at home.

Anyway - a great course, a little slow for me - it is meant for beginners though, so I skipped over some of the material and it was all very enjoyable,.

Udemy - Astronomy - state of the art.

Astronomy - State of the art

I spotted this course just moments before it actually started - well a day or two. I hadn't heard of Udemy before - so this was new.

It looked really good - it promised to cover a lot of areas - and I'm often concious that I only get to see stuff on galactic scales, and mostly theoretical - so this looked like it would be good for balance.

I have to say it was fantastic. You can take the course at your own speed. There was some initial attempts to have quizes as part of them - they had issues getting the system to work so they were shelved.

It really did cover pretty much the whole of astronomy, from telescopes, to planets, to stars, black holes, and galaxies to cosmology - and all stops in between in 77 chunks. It breaks down in the following topics.

As well as videos, there were PDF's to read and slides available. Also supplemental audio recordings of the tutor, Professor Chris Imprey, interviewing other astronomers.

Towards the end of the course he also conducted some live sessions where we could send in questions either live or by email/twitter and he'd answer them live on video conference. They ranged from "Is there life on Mars?" to "What happens in a black hole?" and many others. Nothing seemed to phase him, and each question got a good 5 or 10 minute answer.

The course is still going - and anyone can watch the videos, read the material and take part in the interactive sessions. It's well worth it if you are at all interested.

Even better - after the quantum mechanics course I'd just taken, it was a complete relief to feel on top of a subject!
