Not a developer, but what do you mean in your second paragraph? Do you think people should take more time between jobs or spend part of their (generally two weeks) notice as vacation? Just wondering.

I've read about this a bit for mods on DSLRs for taking older Canon's and allowing them to record video. If the DSLR isn't designed for recording video the sensor isn't designed for continuous light exposure which will heat up an ruin the sensor. I don't know the differences but I'd imagine using one of the newer DSLRs that have video recording capability as a webcam would be fine.

I haven't followed html5 development too closely, but audio support in current browsers hasn't been uniform. I'm guessing the lack of one size fits all for audio in browsers is why.

edit: I'd also guess because audio is hard and that it is probably easier to make graphics and gaming logic than making sounds/music properly.

I've been reading off and on about Bitcoins on HN for a while and had no idea that they could be broken down into smaller units. From Wikipedia:

"In trade, one bitcoin is subdivided into 100-million smaller units called satoshis, defined by eight decimal places.[4]"

I think this partly stems from the term "Bitcoin" itself, since coins are not divisible (having moved beyond pieces of eight long ago). But there are no coins in Bitcoin! It's all just txouts and txins.

You can think of it as a magically valuable liquid flowing down a system of ever-growing pipes representing the blockchain where the transactions are linking points and txins and txouts are pipes with their cross-section areas corresponding to their respective values. Once you think about it, the analogy fits perfectly.

"Coin" in the Bitcoin system is a nickname for a transaction output. The value of a coin can be anything, 1 BTC, 0.000345 BTC, 500,000 BTC...

In maths at my local community college the teacher made lesson plans for the 3 latest editions of the book, allowing students to be able follow along with whatever one they had/could afford.

I do that too. Unfortunately, the college bookstore (B&N) buys up old editions and has them shredded.

I've signed up since then and haven't received any spam at all(also created a new email at the time).

I think the blog post is worth reading and has some good points but the picture does seem out of place.

Regarding 1, enabling Javascript fixed that for me, Chrome Version 23.0.1271.101 with ScriptSave v1.0.6.13 on OSX 10.7.5.

For someone just learning RoR and having installed it via http://railsinstaller.org/, how should I upgrade?

Update the version in your project's Gemfile, and run "bundle update rails".

It should be as easy as 'gem update rails' at your command line (Terminal window).

If you're just learning and creating an app for your own edification, this is not really an issue that will affect you. That is, it doesn't affect how you construct the app, so if for some reason the gem update process doesn't work, you won't be hindered from using RoR.

This won't work. The old version won't be purged, and it'll still be referenced in the Gemfile.

Run "bundle update rails" in your project's root directory (where your Gemfile is).

This won't work if your Gemfile declares a version of Rails (Rails 3.2.9 did this). You have to update the Gemfile and then bundle update.

First do a "gem uninstall rails", wait for that to finish, then do a "pip install Django" at the command line.
