Right now linux is everywhere even in embedded devices. Even Garmn Nuvi series 8XX, 5XXX and 9xx are running linux. So if they are running linux that means they need to release their modifications and sources for this devices. Garmin already published sources here.
The hardware of this devices differ from at device to other but are almost the same:
* Processor — Monahans (Marvell PXA/3xx)
* Memory — “solid state” storage, and probably 64MB of RAM
* Display — 4.3 inches (10.9 cm); 3.81 x 2.25 inches (9.7 x 5.7 cm); 480 x 272 pixels, WQVGA color TFT
* Bluetooth — 1 x Bluetooth 2.0; hands-free dialing feature
* Dimensions — 4.9 x 3.1 x 0.7 inches (12.5 x 7.8 x 1.8 cm)
* Weight — 6.2 ounces (176 grams)
* Battery — removable, rechargeable lithium-ion; up to 4 hours
* Expansion — 1 x microSD slot
* USB — 1 x USB port; optional USB mass storage device is compatible with Windows or Mac OS X only
* Other features — FM transmitter; headphone jack/audio line-out; Garmin Lock anti-theft feature
Off course this is just the most important software what is used not all.
The prices are not such high for such a device. For example Garmin Nuvi 885 costs ~249$ and it knows:
- speach recognition
- bluetooth hands free
- real-time local weather, traffic, movie times, gas prices, stock information, and local news and events
- MP3 player, audio book player, JPEG picture viewer, currency converters, games, and an alarm clock.
- FM transmitter

The main idea behind this bug is to create hashes which collide, because collision will eat a lot more cpu cycles on your server. For a post of 2 MB is resulting in a 44 minutes of CPU time which will results in a DOS. As suggeste […]
Together with some colleagues I started to put the base for a distributed application. Everything is looking good, but we have a big dilemma. We don’t know what communication API to choose.

I should admit, I didn’t read the Glassfish 3.1 Administration Manual, and I don’t know if this is documented. Anyway the main problem appeared when I tried to connect on my cluster instances with admin credentials. If I connect with VisualVM or JConsole to Domain Administration Server (DAS) on 8686 I don’t have any problem. When I’m […]

Until then, all my applications worked flawlessly over the HTTP protocol, but now, after switching to SSL, I got the following error: HTTP transport error: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorExc […]
