Font config ?
by Bev Nicolson 20 Nov '15

20 Nov '15

When everyone's exhausted the mice jokes (pesky meeces) can you apply your minds to this. I have googled and see it's a common problem but didn't understand the solution. While I was upgrading to 14.04, a message came up to say 'font config out of memory lines 14, 23 and 32.' It now says this when I switch the computer off. So, what does it mean and how do I fix it?

Mouse trouble
by Bev Nicolson 20 Nov '15

20 Nov '15

Not sure what's up with my mouse. I asked someone in a reputable computer shop recently about the fact that my mouse exhibits odd behaviour. It'll crash if I have two browsers open and playing a video, for example. He suggested upgrading to Ubuntu 14.04LTS. Which I have done and it's worse. Switching off and on again is the only thing that works. New mouse? Bev

Simple CCTV app
by Mark Rogers 18 Nov '15

18 Nov '15

I have a couple of Wifi IP cameras that I'd like to record output from. I can either capture an image or (I think) an RTSP stream. I just want to store them somewhere I can refer back to them in future if needed. Ideally making efficient use of storage. Any suggestions? At the moment I have ZoneMinder installed but it's quite big and heavy, I frequently find it isn't running (eg after a system update) and it stores all the images as JPEGs rather than as a movie, where I would have thought that the latter would be rather more efficient. It crossed my mind I could probably script something that captured images at a regular frame rate and then turned batches of them into videos later, but there's probably a way to avoid reinventing the wheel. Note: The camera is constantly seeing motion (it's view is through a tree apart from anything else) so motion detection isn't much use unless it can be quite intelligent. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Case insensitive scripting
by Chris Walker 15 Nov '15

15 Nov '15

Hopefully somebody can point out my error with a script. This is it =================== #! /bin/bash # Script to extract thumbnails from .ts files for use on a Humax machine set -e # set -x # shopt -s nocasematch for FILE in *.ts do bname=$(basename "$FILE") dir=$(dirname "$FILE") # extension="${bname##*.}" filenamewoext="${bname%.*}" imagefile="${dir}/""${filenamewoext}.png" ffmpeg -i "$FILE" -vframes 1 -ss 00:01:00 -f image2 "$imagefile" done =================== My problem is that I can sometimes have .ts files and others .TS files so how do I persuade bash to search for both case types? As you can see, I've tried setting 'nocasematch' but it's commented out as that doesn't seem to work for me. Searching online produced the 'tr' command but how do I apply that, if indeed it is the correct solution? Any help appreciated. -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

Has anyone used or know anything about FibreWiFi Limited?
by Chris Green 15 Nov '15

15 Nov '15

While searching around recently for good broadband deals I came across FibreWiFi Limited. They offer direct WiFi (as in microwave based) internet connections. The prices seem quite reasonable, see:- http://www.fibrewifi.com It looks like we should be covered looking at their coverage map. So I'm very interested. Does anyone know anything about them? -- Chris Green

Mount issues
by Chris Walker 07 Nov '15

07 Nov '15

Hello, Can somebody point me in the right direction please? I'm trying to mount another linux box and although it mounts, I can't write to it which is my desired aim. The box in question is a Humax Freeview machine and I can telnet into it and run commands from the command line and having installed ntfs-3g on it, I can now delete files from an attached usb drive using the screen menu on the device. The files are iPlayer programs which I download here, on my Magiea 5 machine. Before I installed ntfs-3g, the contents of the fstab on the Humaxc looked like this :- /dev/sda1 on /media/drive1 type ntfs (ro,uid=0,gid=0,fmask=0177,dmask=077,nls=utf8,errors=continue,mft_zone_multiplier=1) Afterwards, and after a reboot, it now looks like this :- /dev/sda1 on /media/usb-drive1 type fuseblk (rw,nosuid,nodev,user_id=0,group_id=0,allow_other) As I said, it mounts here but all the files are owned by root and of course I can't copy new files to the USB drive. I can FTP files to the box using humxftp as the user and a password of 0000 so my question is, what should I have in the fstab file on my machine to allow me to read from and write to the usb drive on the Humax? In case you're curious, the relevant line from my fstab is currently this :- //Hummy/media /home/chris/Humax_Fox_HDR/ cifs nosetuids,uid=0,gid=0,credentials=/etc/samba/auth.hummy.humaxftp,sec=ntlm,_netdev 0 0 and the credentials file has two entries for user and password as in the FTP command. Any help appreciated. -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

Cross platform (desktop) event driven comms application development
by Mark Rogers 14 Oct '15

14 Oct '15

I have an application where some software talks via TCP/IP to some hardware but there are issues with the communication. I need to quickly knock together a desktop application (initially running on Windows unfortunately but that's temporary so cross platform is important) that will run on the PC and to start with simply pass the messages back and forth whilst logging them, but will then need to start manipulating the messages as they pass through. So instead of <software> <-> <hardware> I'll have <software> <-> <my app> <-> <hardware> In effect I'm putting together a (legitimate!) man in the middle "attack". What tools would anyone here use? Node.js comes to mind (i have no experience of it). Probably Python with a suitable socket library (again, no experience...). The result needs to be fairly reliable (so will need to sensibly handle dropped connections, and not leak memory or lock up after a few hours/days). Obviously that depends on me doing things right but some tools make that easier than others... My app doesn't need a GUI; a hand edited text file to provide configuration will suffice. But the ability to add one if it becomes useful would be handy. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

How to add a file to a mercurial repository and then push?
by Chris Green 07 Oct '15

07 Oct '15

I have a small mercurial project, local and also on bitbucket. I want to add a .zip of the whole thing and push it to the repository but I can't get it to push. I've created the zip, added it, committed it. So locally all is well:- chris$ hg manifest License.text README.md action.php plugin.info.txt rst.zip syntax.php chris$ However it won't push it:- chris$ hg push pushing to /home/chris/dev/dokuwiki/plugins/rst searching for changes no changes found chris$ So how do I get rst.zip added to the remote repository, it's definitely not there, it's at:- https://bitbucket.org/chrisisbd/dokuwiki-plugin-rst -- Chris Green
