The World Sized Robot

I felt this needed to be shared with a broader audience. It may not be news to everybody but far from enough people understands we are just on the verge of something large happening.

We are building a world sized robot

Bruce Schneier writes in his latest CRYPTO-GRAM about something that has been bothering some people for a while as the implications are yet an undiscovered country. But his words are better than mine, so here goes:

We no longer have things with computers embedded in them. We have computers with things attached to them.

Your modern refrigerator is a computer that keeps things cold. Your oven, similarly, is a computer that makes things hot. An ATM is a computer with money inside. Your car is no longer a mechanical device with some computers inside; it’s a computer with four wheels and an engine. Actually, it’s a distributed system of over 100 computers with four wheels and an engine. And, of course, your phones became full-power general-purpose computers in 2007, when the iPhone was introduced.

We wear computers: fitness trackers and computer-enabled medical devices — and, of course, we carry our smartphones everywhere. Our homes have smart thermostats, smart appliances, smart door locks, even smart light bulbs. At work, many of those same smart devices are networked together with CCTV cameras, sensors that detect customer movements, and everything else. Cities are starting to embed smart sensors in roads, streetlights, and sidewalk squares, also smart energy grids and smart transportation networks. A nuclear power plant is really just a computer that produces electricity, and — like everything else we’ve just listed — it’s on the Internet.

The Internet is no longer a web that we connect to. Instead, it’s a computerized, networked, and interconnected world that we live in. This is the future, and what we’re calling the Internet of Things.

Broadly speaking, the Internet of Things has three parts. There are the sensors that collect data about us and our environment: smart thermostats, street and highway sensors, and those ubiquitous smartphones with their motion sensors and GPS location receivers. Then there are the ”smarts” that figure out what the data means and what to do about it. This includes all the computer processors on these devices and — increasingly — in the cloud, as well as the memory that stores all of this information. And finally, there are the actuators that affect our environment. The point of a smart thermostat isn’t to record the temperature; it’s to control the furnace and the air conditioner. Driverless cars collect data about the road and the environment to steer themselves safely to their destinations.

You can think of the sensors as the eyes and ears of the Internet. You can think of the actuators as the hands and feet of the Internet. And you can think of the stuff in the middle as the brain. We are building an Internet that senses, thinks, and acts.

This is the classic definition of a robot. We’re building a world-size robot, and we don’t even realize it.

To be sure, it’s not a robot in the classical sense. We think of robots as discrete autonomous entities, with sensors, brain, and actuators all together in a metal shell. The world-size robot is distributed. It doesn’t have a singular body, and parts of it are controlled in different ways by different people. It doesn’t have a central brain, and it has nothing even remotely resembling a consciousness. It doesn’t have a single goal or focus. It’s not even something we deliberately designed. It’s something we have inadvertently built out of the everyday objects we live with and take for granted. It is the extension of our computers and networks into the real world.

This world-size robot is actually more than the Internet of Things. It’s a combination of several decades-old computing trends: mobile computing, cloud computing, always-on computing, huge databases of personal information, the Internet of Things — or, more precisely, cyber-physical systems — autonomy, and artificial intelligence. And while it’s still not very smart, it’ll get smarter. It’ll get more powerful and more capable through all the interconnections we’re building.

It’ll also get much more dangerous.

Android runner app: iMapMyRun

I was prompted on Twitter to test out the Android mobile app ”iMapMyRun” and so I did today. My first impression was that the software is not there yet, it has not reached a mature enough state to seriously compete with BuddyRunner or Endomondo or CardioTrainer or to be used even for beginners.

When registering I got buttons to select imperial/european units but none of the buttons seemed to work when I pressed them and in the end I had to chose to move on. When I did so I could not find another way to go back and change the settings, nor could I update my personal data such as weight and so on.

Today I took it for a test run and I used other tracking software at the same time. After about 2/3 of the way the iMapMyRun software stopped recording it seems and instead it just plotted the last position when I turned it off at my finish. Therefore it just went in a straight line for the last 1/3 of the run. Definitely something fishy was going on there. Neither did it record the GPS elevation data for some reason, the accompanying web site says ”There was an error retrieving the elevation”, I have no idea why. Of my 5 km run this app recorded only 3.

Both other recording apps (Google Tracks and Endomondo) worked fine through all this. On top of all that it feels unintuitive and quirky and a little backwards but that may be just me expecting things from being used to the other apps in this field.

When the workout finished I got a ridiculous question about peanyut butter, an ad that felt intrusive and out of place. Peanut butter is hardly the stuff for athletes so it felt rather misplaced. The whole app and the accompanying web site is riddled with ads. If you are viewing your runs, you have to upgrade to the payed version or wait 15 seconds before you can see your run. Again it is not on the level with the competing softwares in this respect.

My recommendation is to wait and see if this app matures. In the mean time check out BuddyRunner or Endomondo, both very mature and well working GPS tracking apps for runners.

It gets one running shoe out of five for now.

EasyTether for Android

Fantastic application. Connect your mobile with the USB cable to your laptop, install driver and EasyTether program on your mobile and use your mobile as a mobile broadband internet connection while you are charging your phone!

This is a fantastic development, when I got my Android phone I missed that kind of application and there was some hacks that could be used but nothing that worked this good.

It does not require a root:ed phone, it just works. The software will soon cost a few bucks but it is well worth it if you want to be able to use your phone as a gateway to the internet.

It also uses the phones built-in firewalling capabilities protecting your laptop from attacks from the outside by filtering various protocols. You might even filter UDP ports (except DNS requests) if you like.

The finest Android Applications

This is a summary on my favourite applications on the Android platform. If you have an android phone and wish to test one of the applications, check that you have the ”Barcode Scanner” application installed first, then you can use this application on the QR Codes for each section to automatically get the link to that software in Android Market. Once the code is scanned use ”Open in browser” function.

My favourite Swedish software is described in Swedish at the bottom of this article.

I have found a new software on the net that I really can spend hours and hours toying around with. This is Celestia – a beautiful astronomical and scientifically correct model to the best of our understanding yet of the universe. Celestia works on Windows, Linux and Mac OS X as well.

You quickly learn how to use the zoom in and out features, how to track celestial objects through the sky but the one thing that strikes me the most is how incredibly alone I feel after a while. I have been standing on Phobos and Deimos, looking down on the face of Mars and although they are just small rocks they are quite far away from the planet that they orbit. I have been amazed over how far from the planet some of the satellites of Jupiter and Saturn are and the sheer number of orbiting bodies around Neptune. And then I suddenly stumbled uppon Cassini, the space probe, still going toward the outermost parts of the solar system.

I have traveled to galaxies far beyond a human comprehension and lost myself along clusters too far from the sun that it was impossible to see the Milky Way again. I have discovered the Greater and Lesser Magellan Clouds and amazed that we and Andromeda are so close in a universe on a perverse macro scale.

This my friends are just amazing. And it is freeware. Download, enjoy if you are an Astronomy buff.

Two great utilities

There are two great utilities out there that I use now and then to keep the computer nice and tidy (and fast at that). One is a cleaner utility that can remove lots of old gunk in the machine, cleaning out web browser caches and other such bits and pieces, the other is a very fast and good defragmentation program.

Cardio Training with the Android

Since I got my HTC Magic phone, the second generation Android operating system from Google and a lovely phone I have worked out using two different softwares that I would like to share.

These softwares are CardioTrainer and BuddyRunner, two wonderful applications to help you run well when doing exercise. Both offer similar features and are mainly aimed at runners that want to keep statistics on their exercise and perhaps also their competitions.

The Cardio Trainer Android application

The Cardio Trainer Android application

But what do they do? To make a long story short they are both personal trainers and logging instruments that can upload your running data to a web site where you can review what you have done and compare runs over time.

They are using the GPS in the phone to log your position periodically and thus can calculate your speed. They also measure the time and therefore knows at all times your speed and pace, the distance you have ran so far and in what time you did it.  If you are using earphones and listening to music on your Android mobile as you run they will muffle the music or silence it completely and announce the running data periodically.

Feature-wise they are very similar, CT offers more settings to smooth out GPS positions during a run which can be good if you get bad measurements occasionally but won’t really help much in the long run, so to speak, but after testing the two producs side-by-side I can only conclude they are very similar in the distance they measure when running. The distance on both of them is perhaps a bit on the conservative side compared to distance measured on map or with a really good outdoor GPS (Magellan eXplorist XL) which shows a slightly longer track most of the time. Not certain why this is but they seem to be on the conservative side. My 2 km track registers as 1 850 meters roughly and that is 7.5% on the conservative side.

CT has a huge disadvantage for us Europeans, the tracks it records are shown in metric units on the handheld if you set it up to do so, but on the website everything is by imperial measurements which is really sad because it is otherwise a very good application. I have written them and they are looking into developing it. In fact there’s been two new versions of CardioTrainer released recently both with some small improvements.

The Buddy Runner

The Buddy Runner

BuddyRunner however has a really wonderful web site where you can see the run on a Google Maps interface, statistics on your run such as pace for each part of the run, and elevation. It is interesting to see the elevation go up and the pace time per km increase at the same time. You can compare several runs (up to three) download your running track and it keeps tracks of your records, longest, fastest and so on. Over all it is a much more developed web site than CardioTrainer has. However the application on the handheld is less sophisticated, it does not have the same filters and settings as CardioTrainer does and when it speaks to you it always abruptly pauses the music, the CardioTrainer can lower the volume but keep the music running which is better if you are trying to keep your pace to the music.

In the phone however both applications are very similar however and the settings screen also offers settings to change the announcer frequency and the contents of the announcing messages. BuddyRunner performs well int he background but CardioTrainer wants to run in the foreground, otherwise it pauses. CardioTrainer can also automatically play a certain playlist of music for you while BuddyRunner just leaves the music player alone.

Sharing your things with others is easy on the BuddyRunner, the application and webside can write RSS feeds to your Facebook, Twitter or Friendfeed site and so on, you may show your dashboard to anyone you like, they can’t manipulate it unless you log in but they can leave a comment on your run if they want to.

CardioTrainer has a secret passcode to the webside, you can not display it without this code and when you enter the code you may also remove runs and modify the content, so you would not want to post that publicly. There is also right now no integration with Facebook, Twitter and similar sites, no RSS feeds and the tracks can not be downloaded from the site.

In the end the factor that is the most deciding one for me is the website. BuddyRunner has a much better web site and I love the feature that you can download your runs in GPX format to have them displayed on Google Earth or some similar mapping software if you like. Great stuff!

Direct links for Magellan software

If you are using the eXplorist or Triton series of Magellan GPS receivers you should not miss out on the new fantastic VintagePoint software. And the old MapSend Lite is still there for grabs.

Backup your Windows Mobile

Dotfred’s Space has a backup software free of charge to back up everything on your Windows Mobile device. The problem here is that WM required you to back up contacts and so on using an MS Exchange server. This software allows you to create a backup file and then restore it and does not rely on any other software to do it.

Great stuff if you are using a Windows Mobile based PDA/Mobile phone such as the Ericsson X1 or the HTC series of mobiles. Works with both touch-screen and non-touch-screen mobiles.
