A client is looking for a new embedded system. Their current systems have a 500MHz AMD Geode CPU (which provides a lot more power than they need). A randomly selected system has the following output of "free". So any of the bigger embedded systems (which seem to have 256M+) will do, but the small ones with 32M will be out of the question and even 64M probably won't do. total used free shared buffers cached Mem: 997864 46248 951616 0 7284 21388 -/+ buffers/cache: 17576 980288 Swap: 0 0 0 I'd like to run a fairly stock Debian installation. I guess that a system with 32M of storage would do if I configured it to use a micro-SD card for main storage. The device would need to support at least 2G of storage, preferrably 8G or 16G. Digital IO ports are required as well as a serial port. I guess it's possible to use DTR/DSR and RTS/CTS on a second serial port if a board does everything else right, only 2 digital outputs are needed. The current systems have 2 ethernet ports, 1 for Internet access and 1 for debugging, we could survive with only 1 port if everything else is good. The device needs to be designed for high temperatures, 70C operating temperature will do. Basically it would be pretty ideal if I could get something like a Samsung Galaxy S that's rated for 70C and has at least 1 Ethernet port, USB, and digital IO.

Btw its Debian 7. The value 761 also seems like a weird number? Has anyone had any issue with Debian reporting wrong memory?

Hardware donation: IBM BladeCenter + 10 HS21/22 blades

by Avi Miller

Hey kids, I have an IBM BladeCenter chassis with 10 working (and 1 non-working) blades that is taking up space in my house. The chassis works great, and has both gigabit ethernet and fibre channel connectivity. The 10 working blades are mostly HS21s with dual-sockets and anywhere from 2GB - 8GB of memory (from memory). There is also an 11th blade I could never get to work, but could be used for parts, I guess. I’m happy to give the entire lot to anyone who’s willing to come pick it up from my house in Melbourne. :) Caveats: this thing is large. Like 5RU or 6RU or something. It’s also massively heavy. Fully loaded, it’s probably 60kgs+ or so. It requires 15A power (cables not included) and has four PSUs, so you need significant power supply (though it’ll run with only 2 connected). And finally, it’s stupendously loud. Like imaging an A380 landing about 10m away from you and then double it. This thing wouldn’t sit under someone’s desk. :) I’d prefer to give the whole lot away in one go, and I’d also prefer to give it to a non-profit or educational organisation, or anyone who is going to take hackvantage of it. I bought the whole lot for about $500 thinking I’d be able to do some virtualisation work with it, but the power requirements and noise just weren’t appropriate for a work-from-home environment. If this sound like something you’d like and you have a server room/basement/garden shed/bunker in which to store it, and some way of picking it up from an outer Northern suburb of Melbourne, please email me directly. NOTE: I can’t power the thing up any more, so please don’t ask specific questions about actual memory sizing or processors. I believe they’re Intel Xeon-esque processors. Each blade also has 2x internal HDDs. Essentially, you’re getting the lot for free, so think of it as a blade centre lucky dip! :) Email me off-list if you can take it off my hands. Cheers, Avi

Evolution Crashing

by david.zuccaro＠optusnet.com.au

Hi, Evolution is crashing on when it starts up. This is the error output: (evolution:24495): Gdk-WARNING **: The program 'evolution' received an X Window System error. This probably reflects a bug in the program. The error was 'BadRequest (invalid request code or no such operation)'. (Details: serial 142 error_code 1 request_code 136 minor_code 19) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the GDK_SYNCHRONIZE environment variable to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) I'm using debian and I recently upgraded to 7.3 (not sure if that has anything to do with this). Any ideas as to how I can fix this? Thanks, David ------------------------- Email sent using Optus Webmail
