raspberry pi sd cards
by Brian May 11 Nov '14

11 Nov '14

Hello, In 20912 I purchased a Raspberry Pi B and a 4GB SD card from RS. It worked fine until I tried to upgrade my Raspian version. Basically it crashed the Raspberry pi, and wouldn't reboot. So I installed a new version of NOOBS, and the install worked fine, until the final reboot. After booting is almost complete it comes up with lots of mmc0 errors (possibly "Timeout Waiting for Hardware Interrupt on mmc0" although I will need to double check). A Google search suggested that this is because the SD card is incompatible. Which is disappointing, as I purchased it with the Raspberry Pi so I wouldn't have compatibility issues. Anyway, on the assumption that something is wrong with the SD card, are there are known good SD cards I can buy locally? The list at http://elinux.org/RPi_SD_cards is not helpful, and seems to be full of contradictions. I have read stories of people spending lots of money on SD cards and finding none of them work, so am a bit nervous about doing this myself. Thanks -- Brian May <brian(a)microcomaustralia.com.au>

Re: VirtualBox - remote X11 console

Hi Brian, From: "Brian May" <brian(a)microcomaustralia.com.au> >> X11 connection rejected because of wrong authentication. > > Try running a simpler X client, e.g. xhost or xterm. The VirtualBox configuration tool works and displays on my desktop - so X11 redirect and xauth are "basically" working. (I do not have any other X11 clients on the server) Thanks Peter

VirtualBox - remote X11 console
by Peter Ross 10 Nov '14

10 Nov '14

Hi, since yesterday I have a weird problem. I cannot display VirtualBox _guest_ consoles remotely anymore (the GUI for configuration works). I am running Virtualbox headless on a server but use the GUI for installs when needed. I forward ssh (-X) and use "su -m" to keep the DISPLAY environment variable(DISPLAY=localhost:10.0) and xauth. Two weeks ago I did just that, 1. started "VirtualBox", 2. created a VM and a disk, 3. attached an ISO disk 4. pressed start and the "BIOS" appeared Yesterday it all goes up to step 3- just 4 does not work. I get an error instead of the BIOS screen, and on the server I get: X11 connection rejected because of wrong authentication. I checked all variables and parts - nothing has changed since the last install that worked a fortnight ago. Same kernel, same VirtualBox, same xauth, same desktop. The server is a recent FreeBSD 10, the desktop Oracle Linux 6.5. Do you have any ideas what could go wrong? Thanks for ideas Peter

What's the one > common thing amongst all those SD cards? The power supply. > All manner of curious and exciting behaviour stopped once I upgraded my power supply. I also over-specced the current too. When they say "minimum 700mAH", they really mean "it will light up with 700mAH, but its behaviour will be odd at best". (I have the older model B..newer models may ask for more or less power) I bought a quality 2000mAH supply and have had zero issues since (2 years or so). It's quite boring now :) Mine runs headless and has a 32GB USB stick as main storage, with the OS on SD card, so as far as power requirements go, YMMV depending on how you use it. -- - http://surfcoast.redbubble.com | https://picasaweb.google.com/107747436224613508618 -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- "Unless someone like you, cares a whole awful lot, nothing is going to get better...It's not !" - The Lorax -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- A committee is a cul-de-sac, down which ideas are lured and then quietly strangled. *Sir Barnett Cocks <http://www.quotationspage.com/quotes/Sir_Barnett_Cocks/>* -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=- "A mind is like a parachute.

Thanks Mick, >> I completely removed all the Virtualbox packages and reinstalled from the repository. >> Still problems > I suppose the suggestion was to purge all the virtualbox packages from the repo, than trying to install the one provided by oracle.

It appears to be the same as the one in the repository? Thanks Bob

Still problems - it asks me to run setup still. I tried running it from the Command Line and got this error? bob@Comp-NC:~$ virtualbox WARNING: The character device /dev/vboxdrv does not exist.

Hello all, Since I upgraded to Kubuntu utopic I have been unable to use Virtualbox. It was all working fine prior to the upgrade. I have tried everything so need some assistance. I have unistalled and reinstalled but the problem persists. After the reinstall using apt this is the last part of the install dialogue: Setting up virtualbox (4.3.18-dfsg-1) ... insserv: script virtualbox: service vboxdrv already provided! insserv: exiting now! update-rc.d: error: insserv rejected the script header dpkg: error processing package virtualbox (--configure): subprocess installed post-installation script returned error exit status 1 dpkg: dependency problems prevent configuration of virtualbox-dkms: virtualbox-dkms depends on virtualbox (>= 4.3.18-dfsg-1); however: Package virtualbox is not configured yet.

In 20+ yrs time, these school halls, libraries etc will most likely still be here and would have been used by many thousands of pupils. The pupils attending these schools now could well be parents of the kids using these same facilities in 20 yrs. If you then tell them then about the controversy regarding the funding to build these facilities, what do you think they will be thinking about the Abbott opposition?

Australian School Curriculum
by Brian May 05 Nov '14

05 Nov '14

Hello, At last night's LUV meeting, there was talk of the Australian School curriculum being inadequate for IT. There was a really good keynote talk at PyConAu 2014 that covers topic and upcoming changes for the national curriculum, I would recommend people watch it. (even if it is possibly a bit dated now) See: https://www.youtube.com/watch?v=iVv7fCwVbp4 -- Brian May <brian(a)microcomaustralia.com.au>
