Leaving the lights on

DVD player standby buttonI am an advocate of making sure that every device consumes as little power as possible at all times. Indicator lights should be off, processors should be sleeping as much as possible, and generally the device should just be optimised to use as little power as possible.

I may have to rethink that....at least a little bit.

Dan Lockton has a brilliant blog, Architectures of Control, where he discusses how things are designed to result in a certain action (or lack of action) – or as he calls it, design with intent.

There are two devices in my home which have helped me to reconsider turning off all the lights, my DVD player and my laptop. Each has its own subtle "architecture of control" whether intentional or not.

Our DVD player has (to me) the most irritating standby light that I have ever seen on any device. When on, the light is constantly illuminated, but when in standby the light flashes continuously (at a slow rate). This drives me mad, but results in an interesting action – it causes me to turn it off at the plug when I am not using it (which is most of the time). Suddenly one little flashing light has resulted in more energy saving than having no light.

laptop power indicatorsMy laptop has a similar "feature." When it is powered down the battery indicator remains on (green if full, flashing yellow if charging). This used to bother me, and I thought, "Why not just leave the light off when the battery is charged?" My wife's laptop is like that, the battery indicator only flashes if it is charging, once charged it turns off.

That is all good, except my laptop communicates to me that it is plugged in and consuming standby power when it is not in use. When I unplug it from the wall socket, then the battery indicator goes off – I save the standby power of both the power brick and the laptop.

There is one problem with this, it only works on people who care. If I did not care about saving energy, then I would just leave the laptop plugged in and the DVD player on. That means that you have to consider how your users will handle this kind of subtle feedback and determine whether turning the light off, or encouraging unplugging results in more energy savings.

Sometimes the most obvious design decisions may not be the ones which result in the greatest energy saving. Keep designing for low energy consumption and also keep your mind open to new possibilities.

Innovate for a better South Africa: SA Blook Chapter 10

3 comments : Posted by Duncan Drennan at 09:30 Tags: problems , sa blook , solutions , south africa
This post forms a part of the SA Blook.

shiftSo what is our reality?

South Africa has an unemployment rate of about 23%, a skills shortage crisis, rising inflation, rising interest rates, a large current account deficit and an uncertain political environment – amongst a number of other things.

All of this points towards a great need, and with great need, comes a great crisis...just not the one you are thinking about. The great crisis we have is a crisis of opportunity. Wherever there is need, there is opportunity.

In this midst of this great opportunity the challenge that we face is finding people who are ready to create solutions. We must find and create people who are willing to innovate each day.

We are all innovators and have the ability to contribute to the creation of a better country. Unfortunately we tend to associate "innovation" with technological improvements, while it should really apply to every task that we do. Innovation needs to become a concept which permeates how we do business, and how we go about our jobs each day.

The other problem is that we tend to think of innovation as large leaps forward. Personally I prefer the Japanese concept of Kaizen, which means continuous change for the better (Mind of the Innovator is worth a read). So when I use the word innovate, I mean keep changing things for the better.

On its own, technical advances will only change South Africa a small amount. We need innovation to happen on all fronts – legal, government, business – but most importantly we need it to happen at a people level. We need to find ways to keep changing ourselves for the better, and with that the rest will come easily.

So how do we as businesses and individuals work towards a better South Africa?
  1. People matter

    Our country, and our businesses run on people. The more we place value on each individual, the more value we build for ourselves. It is time to stop thinking about "human resources" and start thinking about people. People matter, and what they care about matters too.

    We are connected to the people around us. Acting in the interest of those around us serves not only to build a better country, but also to nurture and secure our own future.

  2. Engage in the discussion

    We all need to engage in the discussion that is going on around us and try to contribute positively to it. Talking builds community and that forms the foundation for a better country. It helps us find out what matters to other people, and how we can help.

    I have been fortunate enough to be a part of an amazing online business community, The Forum SA, which has brought various business owners and managers together to engage with each other. Together we help each other with the daily challenges of running a business. It also provides a platform for us to work together as a group to improve conditions for small business owners in South Africa. Together we create a better country.

    The more we take part, the more we grow. Maybe it is time to grow together.

  3. Be remarkable: make and do things that matter

    Jim Collin's wrote, "Good is the enemy of great." Or in Seth Godin's words, be remarkable.

    As a whole we have given up our greatness. We have lost our sense of greatness to crime, dirty politicians and corrupt businessmen. Yet as a country we are filled with greatness, even if we are not always able to recognise it.

    What and how we do things changes our view of both ourselves and the people around us. Do your actions reflect who you want to become? Do they reflect the country you want to live in? Do they build your (our) greatness, or break it down?

    What comes out of us, both in actions and words, reflects not only who we are, but who we are becoming. What steps did you take on the road to greatness today? We need to walk that path – one step at a time.

  4. Do more with less

    Right now we can all feel the pressures of inflation. There are two basic ways to combat inflation – consume less, or produce more. If we can do both at the same time it is a double win. Innovation can help us to both increase productivity as well as decrease costs.

    As much as technological innovation can help, finding new ways to equip people with skills and increase their productivity can help even more. As we educate people through schools, universities and on–site training we grow our ability to deliver. As we produce and deliver more we push down inflation.

    Each of us has the responsibility to help develop another person. Remember, people matter.
In summary, we must innovate how we think of people, the things we say, what we do, and how we think.

The thought that I would like to leave you with is a question that I have been asking myself quite a bit lately – what is your reality? Think about that for a second before answering. We get bombarded from all directions (media, government, business) by someone else's reality (or one they want us to believe). Too much of that starts to change the way we see our reality.

So, when we strip it all away, when we really look at the exact details of your life, it may be that things are a lot better than we have been led to believe. Spend some time thinking about it.

What is your reality? How can you keep changing it for the better?

Follow me on Google Reader (forget twitter)

2 comments : Posted by Duncan Drennan at 20:27 Tags: duncan drennan , engineer simplicity
google reader logoGoogle Reader recently released a new feature which enables me to share some more of my thoughts with you.

I have never been a big fan of regurgitating other people's post and information on my own blog. I see this more as a place to try to share my own thoughts and ideas, or bring a bunch of info together to express a new opinion (I hope I manage to!). So far I have been pointing to blog posts that have stood out to me via the "Interesting article's I've recently read" section in the side bar.

The links in the side bar are the most recent items I have shared using Google Reader. Up until recently, it was only possible to share things that I received via feeds (see below if you don't know what a feed or RSS is). What the clever guys over at Reader have now done is to allow me to share anything, from anywhere and add my own note to that.

This is a new form of microblogging, but is far more interesting (to me, and hopefully to you) than the alternatives, such as twitter.

So now you can follow me and see my thoughts on interesting articles and information that I find. There are a couple of ways to do this.
  1. Subscribe to my Google Shared Items feed. If you know how a feed reader works, you'll know exactly how to use that link to follow me. Otherwise, see the info about feeds and feedreaders below.

    There are one or two minor drawbacks with this, mainly that the original author's name does not come through correctly when I add a note.

  2. If you already use Google Reader you can add me as a friend and my shared items will show up in your Reader. This is a slightly more complex process and requires you inviting me to chat with you via Gmail or Gtalk. You will need my Gmail address, which is duncan.drennan at the expected ubiquitous domain name.

  3. [Update] As Francois quite correctly points out, you can also view my shared items as a webpage (which is linked to in the side bar).



Here is some info for those of you who have never heard of a feed or RSS. On this site subscribing to the feed allows you to immediately receive the latest posts straight into your feedreader.

A feedreader fetches information from a whole bunch of different feeds (e.g. this blog, a news website, etc.) displays them for you.

The beauty of this is that
  1. You can subscribe and unsubscribe extremely easily (just add or delete a feed from your feedreader).
  2. Delivery is guaranteed. Because you fetch the feed (pull) unlike email which is sent to you (push) the feed cannot get lost due to a firewall which is trying to stop spammers. Feeds are spam free!
  3. You never miss a post. This is particularly important if you keep up to date by coming to check back here regularly. You could miss something, or worse, stop coming back ;)
Once you start using feeds you will wonder how you survived without them. I use Google Reader as my feedreader, but there are plenty of others out there. Here is a really useful video which explains RSS and feeds a lot better than I can.
