3 Ways Google Applications can enhance teaching

Having recently started working at a school where email, calendars, documents etc are hosted by Google Applications, I felt that it would be worth while incorporating these into my teaching and planning. This post describes the benefits I have found from this in the first few weeks, and will outline some plans that I have for the future. If you haven’t used Google Applications in a workplace before, then here’s a quick outline of what’s included in the free version.

  • Gmail (7+ GB of storage)
  • Google Calendar
  • Google Documents
  • Google Sites
  • Google Talk
  • A version of iGoogle called Start Page

Benchmarking Chrome’s V8 Javascript engine

Having previously looked at the memory usage of Google’s Chrome, it’s time to analyse it’s much mentioned javascript engine, V8. Assumedly named after the engine with the same name, V8 compiles javascript to machine code, rather than bytecode to achieve greater performance. In this respect, it’s similar to Firefox 3.1′s TraceMonkey, a JIT javascript compiler again developed to achieve much greater speeds when running javascript.

Google Chrome Memory Usage

Google Chrome Memory Usage, originally uploaded by Rich Bradshaw.

Browsing to about:memory in Google Chrome gives you this interesting display showing memory usage for both itself as well as other browsers running.

According to the browser, this is the memory usage of the following browsers on blank pages. (Although Chrome is on the about:memory page, that’s a different process, as shown below, so that doesn’t mess things up.)

A Vision of Students Today


An interesting view into how students live today. I’m thinking that it depends what degree you study on how much work and classes you have to do – 3 hours of class + 2 hours work a day is much less than I did, and I only graduated last year!

Also, noone brought laptops to lectures – we didn’t use Facebook all through lectures, the material was much to complex to do that and still pass!

5 mistakes new web developers often make

Having talked to some university students who had taken computer science/IT degrees, I was amazed by how little they seemed to know about making anything that’s secure or even remotely logical. The group I met with primarily had been taught PHP. Having looked at some sites they were designing I realised 5 things that they had no idea they had done incorrectly, here’s a run down:

Powerset: Find Factz, Get a T-shirt

The new semantic search tool for wikipedia, Powerset, have just announced a competition challenging users to find interesting “Factz” using their search tool.

So far, I’ve found:

Powerset: What eats humans?

What eats humans?

We have the usual: zombies, monsters and sharks, but the list also includes Catholics, foxes, streets and pigs…

Powerset: What do chickens like?

What do chickens like?

Only three things, potatoes, ham and tandoori. That’s good to know…

Google have released a section in the settings tab of Gmail called labs. This was predicted by a few blogs recently, and it seems to have come true today.

The new labs section includes:

  • Quick Links: Add links to the sidebar for any bookmarkable page in Gmail. This lets you add custom searches, filters etc.
  • Superstars: More choices of star to mark messages.
  • Custom keyboard shortcuts: as it sounds!
  • Mouse Gestures: again, as it sounds!
  • Signature tweaks: lets you get rid of that annoying — before you signature, as well as allowing the signature to float above the reply.
  • Old Snakey: Play snake in gmail…

These features are all rather random, but it will be interesting to see if anything more interesting appears in here.

Need newer software for Ubuntu?

It’s been around for a while now, but getdeb is still a very useful tool. It has links to hundreds of .deb files for easy installation of newer software that hasn’t made it’s way to Ubuntu yet.

For starters, try installing:

Much nicer than compiling from source!

How to: Get all Facebook friends + emails into any address book!

With the release of Microsoft’s Invite2Messenger, we can now get all our Facebook friends out of Facebook, and into our address books. Useful for finding your friends on other sites, as well as for emailing them!

1. Go to: https://www.invite2messenger.net. If you get a warning about the security certificate, just allow it.

2. Choose Facebook (other sites are to come, including Hotmail, Bebo, LinkedIn, Hi5 and Tagged…)

3. Stick in your email, and click “Find Friends”

4. Once you have the list of all your friends and their emails, select the text on the page, and copy it into a text editor.

5. You now have the information, use find and replace to get it into this form:

name1,emailaddress1

name2,emailaddress2

etc…

6. To import into gmail,  make the first line of the file:

Name,E-mail

and save the file as a .csv.

7. Go to gmail, then choose contacts. Choose import at the bottom of the page, and choose your file. Gmail automatically checks for duplicates before it adds the new addresses, and merges them when there are duplicates.

For other email providers, check their help on the file format needed. Gmail can export in some different formats, so perhaps it’s a good idea to put it through Gmail to get the others.

8. Go to twitter, last.fm, digg, friendfeed etc etc and use their friend finders to find out which of your friends are on those sites!

Hope this is helpful!

Much easier than trying to screenscrape the page…
