Use CurrentCost to see how your electricity usage compares with others

October 14th, 2008

first beta of a web services based CurrentCost appI’ve played with ways that CurrentCost users could compare their usage with their friends for a while.

But now I want to see how it will cope with a bigger group of users.

Want to join in? I’ve started writing some instructions – please do give it a try!

Find out how here.

Update: I figure that if I’m asking for people to help me, then it’s only fair that I give something back. So I’ve made available the Python source that reads and parses CurrentCost updates.

Making your own font

October 2nd, 2008

hosted on Photobucket

It was my wife’s birthday last week. As a part of the birthday present that our three year old, Grace, made for her, I made a font based on Grace’s handwriting.

This isn’t terribly technical, or even new. But I thought it was cute. 🙂

Comparing your CurrentCost data with others

October 1st, 2008

a Python CurrentCost appBetween holidays, meetings, work and other stuff, I put CurrentCost stuff to one side for a few weeks.

I’m back now, and thought I’d share my plans for the app. If nothing else, I figure it’s useful for me to refresh my memory and plan my next step!

Palm Treo Pro

September 30th, 2008

I’ve had a Treo Pro for a couple of weeks now so I thought I’d write a post about what I think of it.

If you’re the sort who likes to skip to the end of stories, let me save you a little time. I’m loving it. It’s awesome.

I’ll try and explain why in this post.

Programmatically accessing authenticated Google App Engine services

September 19th, 2008

This one has been bugging me for a few days, and with help from a very helpful Google engineer I’ve finally got this working, so I thought I’d share my code where the next poor soul to try and do it might find it!

The problem:
I’ve written a small web service which I am hosting on Google App Engine.

By adding “login: required” to specific services in the app’s app.yaml file, I can make sure that you need to login to access a service.

If you’re accessing the service from a web browser, this is fine – you get redirected to a Google login page, and after entering your username and password and hitting ‘submit’, you get sent on to the web service you wanted.

But how do you do that programmatically? I wanted to do it from a Python application on my desktop, without being able to navigate the HTML login form.

Google Developer Day London

September 17th, 2008

falling through the floorIt’s been a very geeky week – only a couple of days after BathCamp, I was in London yesterday for Google Developer Day.

I was saying only a couple of days ago that I really need to get my head around some of the options out there for web developers, so this was well timed.

I learnt about web development tools and online APIs, talked a lot about where mobile development is going, and got to wander around Wembley Stadium. All in all, it was a good day. 🙂

ooh - a present!The underlying theme for the talks throughout the day was showing how Google are trying to make the web ‘better’.

The messages were grouped into four key areas:

  • “client” – making the browser more powerful – through Chrome, and Gears
  • “cloud” – making the cloud more powerful – through the various APIs they make available
  • “connectivity” – making web apps more powerful – through web development tools like GWT, and Android for mobile
  • “social” web – making the web more social – through OpenSocial

I made a ton of notes throughout the day. Rather than write the world’s longest blog post, I’ve picked out a few interesting bits.

BathCamp

September 14th, 2008

I’m home from BathCamp – the Bath barcamp. I don’t have a lot to say about it, but wanted to post a quick thanks to all of the organisers.

This was my first barcamp outside London. I mainly went because Bath is my old Uni town, and any excuse to go back is always good. But I’m really glad I went – and will definitely be looking out for more non-London developer events.

A few random thoughts from my sleepy brain…

del.icio.us pecha kucha: ten seconds to describe each of the last ten pages that you’ve saved in del.icio.us. Similar to delicious.salted.com but driven by a Python script, we took turns to give it our del.icio.us username, and each of our last ten saved webpages were opened in turn and displayed on a big screen. Very neat idea, and one that I will have to steal at some point. It makes for a fascinating geeky ice-breaker.

CurrentCost @ BathCamp

September 13th, 2008

I’ve uploaded the slides I used for my CurrentCost talk to SlideShare.

They probably wont make much sense without my rambling to go with them, so I’ll try and add some notes to them at some point.
