Backporting uvcvideo to an older kernel
by Toby Corkindale 18 Feb '14

18 Feb '14

Hi, I have a little ARM board (radxa rock) which unfortunately only has support in a modified 3.0.36 kernel. Maybe the Chinese manufacturer will honour the GPL at some point and release source code, but for the moment it's all we've got :/ Unfortunately, I have some USB webcams that aren't support in that old a kernel; I know they're supported by 3.4, possibly even earlier. Has anyone tried backporting the uvcvideo and supporting video4linux modules? Just wondering if it's likely to go well or if I'll be wasting my time. Cheers, Toby

expect script for FTP
by Russell Coker 15 Feb '14

15 Feb '14

The attached script can be used to get files from the Olive Tree FTP server in a fairly default configuration on an Android phone. Consider it as an example of what can be done with expect. The script takes a single command line parameter of the IP address of the phone. The user-name and password are the default for the Olive Tree FTP server. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

strange NFS problem
by Russell Coker 15 Feb '14

15 Feb '14

/data 10.1.2.3(rw,sync,no_subtree_check,no_root_squash) I have the above in /etc/exports, root on the NFS client can't run chown, it gets EINVAL. Both client and server are running Debian/Wheezy but the server has kernel 3.11 from Debian/Unstable (for BTRFS). I don't think it's a BTRFS issue as I have another BTRFS NFS server that works well. Any suggestions as to what I should investigate? Please include the "obvious" things as I probably missed something that's supposed to be obvious. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

capture and storage of marine AIS data
by Andrew Mather 11 Feb '14

11 Feb '14

Hi, I have recently added an AIS receiver to my gadget collection. The device was supplied by Marinetraffic.com and is configured to send the data it receives via the internet to populate the live chart you see on the web page there. There's a number of stations around the place, all of which contribute to the chart on a first-in best dressed basis for each position report. One of my areas of interest is VHF propagation and recently I noticed on my station's coverage graph that there had been some 'troppo' about and I had received signals from over 1000km away. Unfortunately, the Marinetraffic website only shows a sliding 2-day window of coverage and so I "lost" the chance to grab a screenshot before I realised. The device (a Comar SLR300N) also has a USB port through which data can be captured locally. I currently have this talking quite happily to OpenCPN on my Kubuntu machine and displaying the data received by my station, which I can compare against the live chart on the website. I'd like to be able to tap the USB output and grab the data as it comes off, parse it and store it locally so I can play around with it. I have found various bits and pieces, that do part of the job, but my attempts to glue it all together have been a bit Heath-Robinson. I believe the device sends NMEA sentences. I have verified this by using aisdispatcher and dumping the output and then using an online decoder/parser to view the data, but have not yet succeeded in setting it up to run a local routine without way more manual intervention than I want. Just wondering if anyone else has played with such devices and done a similar thing ?

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