October AGM and Elections.
by Bill Thanis 08 Sep '15

08 Sep '15

Good afternoon ladies and gentleman, I have been appointed the election's returning officer, aka the guy who counts the votes. There are two openings for the board this year. We are looking for people to fill the vacancies. If you wish to run for the board please send me your name. Officially, I will need a member to second your nomination, but that can be done at the AGM in October. Although this is not a big commitment of time, please understand that it does involve a commitment. There is one monthly meeting of the executive which includes the board to discuss operational issues that you are expected to attend. Thanks, Bill

Digital (NH4) 2Cr2O7
by Russell Reiter 07 Sep '15

07 Sep '15

This is an odd subject title I know but a rather interesting POS security issue. Everybody has a story. People involved in computer security and intelligence have war stories, I have a few builders stories. Here is one of them. > > (NH4) 2Cr2O7 is the chemical formula for ammonium dichromate. It's a chemical which was used in developing colour film, with a few other notable characteristics. One of those is that when it is burned the resulting ash is seven times the volume of the original orange/red fine powder that it is, although that's not material to what I relate now. > > When I 'prenticed in the building craft I met a lot of property developers some of them had, well lets call them skills. These skills were a part of what you might call the long con. As opposed to the short con where you just take the money the mark has with them at the time. > > I had a meeting with a fellow at a patio bar downtown and after our talk we had a few beers and we were discussing the new banking technology which allowed you to take money out of the bank from a machine outside the bank at any time day or night. > > This is what he told me when I was expressing how easy this made it for me to do my banking. He said, what if you lose your card, I said it has a password. He said if I can get hold of your card even for a short time, I can get not only your password but your account number and address. > > I said yea right how are you going to do that. He said ammonium dichromate. I knew what that stuff was from witnessing the volcano chemistry demonstration relating to the volume of the ash. > > So he told me that he could sprinkle the powder on the magnetic stripe of my card. The powder would stick to the magnetized portion of the tape. This would reveal the bar code and he could then duplicate that code on to a piece of blank reel to reel audio tape, use a barcode reader to harvest the plain text and get my pin and my address and my money then, by pasting that tape onto a piece of stiff cardboard, off to the bank (machine). A library card was just about the right size. > > Here's the digitized version of that technique. It requires a specific cyanogen mod for the NFC. > > m.youtube.com/watch?v=x2rF3dD1Ns0 > > Russell

message from the past
by D. Hugh Redelmeier 06 Sep '15

06 Sep '15

I'm typing this on my first notebook. I bought it in 1999. It is woefully obsolete, but it really does work. - NEC Versa SX - Pentium II at 233MHz - 256M of RAM - 1024 x 768 screen (actually, I like the aspect ration) - 16 bits / pixel (oops) and a Trident video chip (support in X isn't 100%) - Fedora Core 1 - ethernet card plugs into a PCcard slot Via some simplified version of Moore's law, things ought to be better by about a factor of 1000 (two to the power of (16 years / 18 months)). - Processor clock speed is faster by a little more than 10. The work done per clock tick is perhaps 2 or 4 times greater. - The RAM is larger by a factor of 100 (the machine came with 64M). - disk space has gone up by perhaps 250. It came with a 4GB drive and I upgraded it to 10GB - screen resolution has gone up perhaps a factor of 2 horizontally and 1.3 vertically - keyboards don't seem better. Trackpads do. - price has gone down a bit.

Better font rendering for Linux: Infinality
by Stewart C. Russell 06 Sep '15

06 Sep '15

Just in case there's anyone out there still suffering from most distros' appalling font rendering, Infinality can make a huge difference. Some (slightly debian-specific) instructions on installing it: http://www.webupd8.org/2013/06/better-font-rendering-in-linux-with.html Ubuntu 15.04 was still defaulting to a horrible mix of bitmap and vector fonts for certain applications until I installed Infinality. Font rendering is fractionally slower, but at least it looks like it's on a computer display from this century. cheers, Stewart

No sound from Intel HD Audio -- solved!
by William Park 02 Sep '15

02 Sep '15

Hi, Finally, I've got sound from Intel HD Audio, through default card=0 ! I recently bought H97 motherboard and i3-4170, because I couldn't afford electricity for my 125W AMD 8-core and overheating motherboard. According to my calculation, i3 will pay for itself in a year. Everything was ok, except sound. On this H97 board, the default card=0 is HDMI, and audio ports are card=1. - I got KDE making notification sound by changing precedence order in "phonon" setting. - I managed to get 'mplayer' playing on card=1 by ao=alsa:device=hw=1.0 and 'aplay' playing on card=1 by -D default:PCH Still, YouTube or Flash played video, but no sound. Installing discrete sound card would not help, because that would only become card=2. I was about to go back to the AMD block heater, when accidental click lead me to a solution. Solution was ~/.asoundrc pcm.!default { type hw card 1 } ctl.!default { type hw card 1 } Now, I've got sound from default card=1, without those funky configuration settings. -- William

How to install Intel HD Graphics driver?
by William Park 31 Aug '15

31 Aug '15

For NVidia cards, I just download/install NVIDIA-Linux-x86_64-aaa.bb-no-compat32.run It's one file, and it's easy. To run mplayer with VDPAU, I just set vo=vdpau in the configuration file. I assume it's the same for AMD cards. I don't have AMD cards, so don't know. For those with Intel HD Graphics, how do you download/install driver? I went to Intel site, and it's utterly confusing. I just want Intel's driver, so I can try out VAAPI. -- William

(Its a uefi setup) Well this morning - - - fdisk -l shows the array its not mounted the command I used to use for mounting in Debian 7 no longer works so - - - - any suggestions? TIA Dee
