Learning coding
by Bob 27 Jan '15

27 Jan '15

Hello all, I am looking for some opinions on how to best support the development of coding skills in a child who is interested. I'm not sure if this is the correct forum or should it be Luv-talk? He has built a Kano computer (Rasberry Pi based) and followed the programs it provides. As a next step I am looking at Code Academy which offers tutorials in about 6 languages. Could someone please offer a view as to where is best as a starting point, or is there perhaps a better route to follow? Does he start with web languages and then progress to Ruby or Python? All advice would be most welcome. Thanks Bob

Debian/stable won't boot
by Brian May 27 Jan '15

27 Jan '15

Hello, I have a i7 based HP computer here that until recently was booting Linux and Windows just fine. According to the user, it stopped working after updating the graphics drivers under Windows. Anyway the symptoms are: * Grub loads fine. * Selecting any Linux kernel from grub, results in the computer freezing immediately after loading the kernel (no time to initialize the kernel), with a black screen. * Selecting memtest results in similar problems. * Same thing happens booting from rescue items in grub menu. No extra debugging information. * Keyboard unresponsive after crash. Caps-lock, num-lock, and Ctrl-Alt-Delete don't work. * Booting windows works fine. * Booting Debian live CD image on USB works fine. It has the standard Debian wheezy kernel, 3.2.0-4-amd64, which is the same as one of the options I was attempting to boot from the hard disk. * Power cycling is the only way to un-crash the system. Extra facts: * It is a Nvidia GeForce GT 640 based graphics card * The live CD does not use grub. * Debian/wheezy based system with extra kernels installed from Debian backports. * The dog barking does not make any difference what so ever. * Nvidia closed source drivers not installed (not that I see this making any difference, as the kernel doesn't appear to be started when it crashes) * This is a UEFI boot system, with secure boot turned off. Have tried installing another kernel after booting live CD, and reinstalling grub, however nothing changed. Have run memtest from live CD, no errors reported. Only thing I can think of is that the update of the graphics drivers under Windows has updated the graphics card firmware breaking boots from the version of Grub in Debian stable/wheezy. Does this even make sense? Any other ideas? Thanks -- Brian May <brian(a)microcomaustralia.com.au>

nfs on btrfs and --reflink
by James Harper 25 Jan '15

25 Jan '15

I have a btrfs directory exported via nfs. Are there any secret mount options that would allow 'cp --reflink' on the nfs client to work (eg pass the required IOCTL to the server via nfs)? Thanks James

Converting documents with pandoc
by Jason White 21 Jan '15

21 Jan '15

I would welcome comments (favourable or otherwise) from anyone on the list who has used Pandoc to convert documents between various file formats. In particular, I'm interested in the possibility of using it to write papers in Markdown format (using Pandoc's extensions), then converting them to any of ePub, HTML, PDF (via LaTeX), MS-Word docx/OOXML, ODF, etc. Pandoc also supports automatic citations and bibliography generation, a highly desirable feature. I plan to experiment, but, as always, comments from those who have taken this path already would be informative.

calendaring
by Russell Coker 20 Jan '15

20 Jan '15

A client of a client has problems with Outlook and they are looking at moving to different software. A basic Postfix/Dovecot installation does everything they need for email but the issue is calendaring. They want "shared diaries" with Outlook clients and phones, I think mainly iPhone. What is involved in setting this up? Apache has built in WebDAV support, what else do I need? -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Getting mate-sensors-applet to appear
by Carl Turney 20 Jan '15

20 Jan '15

Hi, I've downloaded and installed sensors-applet (AKA gnome-sensors-applet, AKA mate-sensors-applet) into my Linux Mint Mate 17 (Qiana) systems. But it doesn't appear on my (bottom-edge) panel, and none of those three names appear when I enter Menu - All Applications - All (so that I can right-click and Add To Panel). Searching my computer yields 107 files and folders, including 2 executables... /usr/lib/mate-sensors-applet/mate-sensors-applet 77.9 kB /usr/lib/x86_64-linux-gnu/sensors-applet/sensors-applet 86.0 kB ... but I haven't been game to just execute them from the search window. Any suggestions on how I can... (1) get it running on each bootup (2) have it appear all the time in the panel (3) enter its configuration mode (to set the temps, etc.)? Thanks very much in advance, Carl Bayswater, Vic

Woeful Thunderbird Performance
by David Zuccaro 16 Jan '15

16 Jan '15

Hi, Hope you're all keeping cool on this rather oppressive day. I have an i5-2450M CPU @ 2.50GHz with 4Gb of memory running linux mint 17. As the title suggests I'm finding Thunderbird to be very sluggish so I would welcome suggestions to help boost performance. (actually evolution was better in this regard) I have moved about 6 years worth of emails into the archive directory -- I presume exporting these out of Thunderbird into a searchable format (which one?) would help matters. Alternative mail reader suggestions are welcome. I'm using gmail (imap.googlemail.com) should I look at hosting my own email server? Digital ocean? On a related note: is there a searchable online archive of luv-main posts? The only thing I can find is this: http://lists.luv.asn.au/pipermail/luv-main/ which doesn't seem very satisfactory. I was storing about 6 years worth of luv postings but I deleted them in a vain attempt to rectify the above problem.
