Lucid Nexus One Development
- You have to keep redoing it every time you start up your dev environment
- Running a potentially insecure service as root!!!
- If you do restart it while eclipse is running, you get some extra output in the console window
- Unplug your device!
- Create a file as root: /etc/udev/rules.d/51-android.rules
- Paste this line into the file: SUBSYSTEM=="usb", SYSFS{idVendor}=="XXXX", MODE="0666"
- Lookup the vendor id in this table ( from the android dev site linked above ) and replace XXXX with your devices vendor id:
If you're using a Nexus One, like myself, the vendor id is NOT in that table! At least for some reason, my vendor id registers as: 18d1Manufacturer USB Vendor ID Acer 0502Dell 413cFoxconn 0489Garmin-Asus 091EHTC 0bb4Huawei 12d1Kyocera 0482LG 1004Motorola 22b8Nvidia 0955Pantech 10A9Samsung 04e8Sharp 04ddSony Ericsson 0fceZTE 19D2 - Save and close the file. Plug in your dev device, and start up eclipse/adb.

Intruder alert
Otherwise, i have done some testing of Motion Detection software for Linux, and here is a brief overview of what i have discovered.
There appear to be 2 developed solutions, ZoneMinder and Motion.
ZoneMinder:
This seems to be the more well known and more established of the 2. It appears to have lots of binaries available, but sadly mostly for debian based platforms. If you need to compile it from source, it becomes a complete nightmare of weird dependencies, many of which i didn't know existed. It took several hours to get configure to run, and in the end, i could compile it, but it crashed on launch. Not very impressed. I also noticed that it was heavily perl based, and while i have no problem with that, it did make things more complicated than they could have been. That said, the screenshots show some fantastic features, and i'm sure that if you can get it up and running, it's a great - although possibly overcomplicated - piece of software.
Motion:
This also had a few odd dependencies, but took no more than an hour from download to simple motion snapshots working. After working out how to set up the config file, i also got the built in webserver running. From here, i need to set up a remote viewing and config site and an email notification service, which shouldn't be too hard. Overall, this software is considerably easier to setup than ZoneMinder however not as feature packed. This does, however, do everything i need it to do, and has some nice extra features which i thought i might have to build myself. It may be simpler than ZoneMinder, but it is definitely extensible. It also includes setup for proper LAN security cameras and the built in webserver has some nice features. There are also some smart features such as automatically drawing a white box around the area of motion in the image.
Conclusion:
If you just want to set up a simple motion detection camera for home, i recommend Motion, as the setup was simpler, and it does the basics really well. If you need a bigger solution, and potentially have a PC to spare just for this purpose, then ZoneMinder is probably what you want. In the end, i'm just really glad to see some motion detection solutions for Linux.

When the Contribution Model Fails
I'm a big advocate of Open Source software. I feel that there really is no reason to close software source for the most part, and in general, closed libraries are very frustrating for me as a developer. However Open Source has it's flaws. The contribution model may be one of it's greatest strengths, but is also a big weakness.
What leads me to this "revelation" is an issue which i've been considering getting involved in and fixing. It's a Gimp enhancement request, which is probably the thing that annoys me most about Gimp at this moment. The "bug" is the lack of grouped layers in Gimp. Obviously, not having groups for layers can make a large document really convoluted, but more than that, i often find myself wanting to make modifications to multiple layers at once, such as opacity or translations. So what's the problem? Surely if they know about it and it's in their list, i should either do it myself or just be patient?
It's a 7 year old feature request.
I do understand that "implementing this feature is not trivial", but 7 years is not even close to acceptable. I realise they are suggesting it might make it to version 2.10, possibly in 2011 or 2012? Before the end of the world i'd hope. But seriously, in the commercial world, people lose their jobs for taking over a month to implement features like this. This is not easy to do, but in that time the KDE guys have written Krita from scratch, which may end up soon overtaking Gimp in features, and already has grouped layers. To me it almost seems like no one wants to take on the task.
What happened to open source being the cradle of innovation, instead of lagging behind commercial competitors? In Gimp, you have the Open Source stereotype. It's not as good as commercial counterparts, and lags several years behind in features. Some Open Source projects really seem to suffer from this. I'd suggest that X.org is another that just can't keep up with feature requests. Is it because of a poor codebase that people struggle to build on? Is it because of lack of interest in the project from outside devs? I'm not sure, but it really does bring down the quality of some big Open Source projects.
On the other hand you have the entire KDE team as an example of real innovation. The KDE desktop is years ahead of any competitor, the codebase is beautifully clean, and they are churning out major features in just a few weeks. My example of Krita is a very pertinent one. It may turn out to be a big threat to Gimp in the long run, especially because it is now cross platform. The pace of development is clearly much faster, and it seems that it already has some of the modern features Gimp lacks.
In the end this does highlight some of the problems with the contribution model of Open Source software. Some projects fall behind, potentially become aged, while others forge ahead. How do you prevent a split like this? Should similar projects collaborate? Does that then remove an element of choice? The way i see it is that if it is needed enough, someone will do it. Maybe thats why Krita is moving so quickly, compensating for Gimp's inadequacies? It's probably also why Google are going to replace X.org in Chrome OS. After all sometimes its good to do some spring cleaning.

Opera does something right, again!
In KDE, i disabled the window border, and in Opera moved the tabs to the right... this is a browser experience i can certainly get used to!
