Scanning and OCR
by Mark Trickett 14 Aug '17

14 Aug '17

Hello All, I have been scanning with "scanimage" and rotating with "convert" with a degree of success. From this I deduce that the "native" orientation of the scan is that it starts from the top, while I have tended to scan the other way. I have googled about scanning, and bothered to install "unpaper" and "tesseract-ocr". I am having a bit of trouble sorting out the l, t, x and y parameters, where they offset from and the like. I will manually initiate each scan as there is no auto feed, which would not be applicable with a magazine or book anyway, so can increment a number in the filename, although some good explanation of doing so would be appreciated. There are also a host of things with unpaper, and should someone have pointers and tips, that would be appreciated. I will then try feeding through tesseract, and any experience there would also be appreciated. If you are scanning with other software, with good results, please also comment on what you use, and why you made the choice. Regards, Mark Trickett

migration
by Russell Coker 12 Aug '17

I've just migrated the LUV VM to a new server. The new system has 48G of RAM and SSD storage. The LUV VM now has 4G of RAM (up from 2200M) and the SSD will improve performance too. Currently while waiting for DNS changes to propagate I have the old VM forwarding connections on ports 80 and 443. Currently we have some performance problems with the Drupal site https://luv.asn.au/ I think that this is partly due to forwarding connections and Drupal needing lots of connections for images, so I won't be too concerned unless it continues after a few hours when people start getting the new IP addresses. But if any Drupal experts would like to look into this I'd appreciate it. Some mail to the lists will be delayed while MTAs cache the old IP addresses. I don't consider this a problem, email is not IM. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Perl related query
by Mark Trickett 24 Jul '17

24 Jul '17

Hello All, I am making another start at learning Perl, and I am looking at installing the -doc module. I do have cpan to do the install, but trying to sort out exactly what the -doc package should be called for the install with cpan. Having the correct argument for cpan would help, but I am also wanting to understand what I need to look for in sorting out the naming conventions for the modules, and how to look up such. Regards Mark Trickett

Playback/audio failure on firefox 52.2.0 on debian 9.0.0
by Erik Christiansen 22 Jul '17

22 Jul '17

Trying firefox on a fresh install of debian 9.0.0, it plays youtube video fine - sans audio. To figure out whether the silence is due to me having to do something more than hook up the hdmi cable and check that the monitor's speakers are unmuted and set to 50%¹, I thought I'd try www.abc.net.au/news and click on the link to the 24 hr news tv channel. But that evinces an "Error loading player: No playable sources found." OK, I did an apt-get install mplayer, with the same result. Then I added: deb http://mirror.optus.net/deb-multimedia/ stable main to /etc/apt/sources.list, and after that an apt-get update: # apt-get install deb-multimedia-keyring gave "E: Unable to locate package deb-multimedia-keyring" In contrast, this older debian wheezy host plays both sites fine. It would be especially nice to get the audio working, as this new Udoo X86 was bought for its claimed ability to stream to three 4K screens simultaneously. ¹ I also tried an hdmi to vga adaptor, with stereo audio cable plugged into the monitor's audio jack (and the monitor menu-switched to vga mode), but that also gave only silent movies.

Error when Installing Debian 8
by zlinew9＠virginbroadband.com.au 18 Jul '17

18 Jul '17

I have (finally) decided to give Debian 8 a try, after some mucking around I installed. THe install medium was an Debian 8.3 i386 DVD, and was upgraded from the net. The install of the kernel produces the following error..... -----------------cut here------------------------ Processing triggers for initramfs-tools (0.120+deb8u3) ... update-initramfs: Generating /boot/initrd.img-3.16.0-4-686-pae mkinitramfs: failed to determine device for / mkinitramfs: workaround is MODULES=most, check: grep -r MODULES /etc/initramfs-tools/ Error please report bug on initramfs-tools Include the output of 'mount' and 'cat /proc/mounts' update-initramfs: failed for /boot/initrd.img-3.16.0-4-686-pae with 1. dpkg: error processing package initramfs-tools (--configure): subprocess installed post-installation script returned error exit status 1 Processing triggers for libc-bin (2.19-18+deb8u10) ... Errors were encountered while processing: linux-image-3.16.0-4-686-pae initramfs-tools E: Sub-process /usr/bin/dpkg returned an error code (1) -----------------cut here---------------------- Now it actually works OK, the ramdisk image was installed correctly. What it has done though it prevents the kernel from being upgraded. I have sort of got around this by compiling my own kernel (I do this as a matter of course anyway), this of course required me to dump systemd as it WILL NOT work with a standard kernel from kernel.org.
