So you have to set a supervisor/admin password for the bios before you can change the secureboot setting?

Thinkpad T420 as a VM host
by Alex Volkov 11 Aug '15

11 Aug '15

So I replaced a 4GB memory stick in my Thinkpad T420 with an 8GB one bringing the total amount of available ram to 12GB with maximum of 16GB.Even though Lenovo say that the laptop supports only 8 GB of ram total. As it stands now this 4 year old machine becomes a pretty cost-effective platform for virtualization: * Intel Core i5-2410M * 16GB max memory (~$65 per 8GB stick). * 2 SATA ports (built-in and ultrabay) * 2 mSata ports (one could be used for solid state storage) * 1 eSata port. * 1 Gigabit ethernet * 1 SD card Canada computers sells refurbished ones for about $300 and I think there are some available in Brampton. Also I saw a few similar refurbished machines on Amazon. Alex.

Hello KevinYes it was I that you informed.I will be getting to one of those computers give give some of the ideas a try.So, unless anyone has any additional thoughts that may help, it is up to me to check it out and get back to the group with the results.Thank you all for your help.Cheers Abby Sent from my Samsung device -------- Original message -------- From: Kevin Cozens <kevin(a)ve3syb.ca> Date: 08-11-2015 11:27 (GMT-05:00) To: talk(a)gtalug.org Subject: Re: [GTALUG] UEFI bios/firmware On 15-08-11 10:47 AM, Abby wrote: > In at least 3 computers I have come across, that has this option grayed out. I mentioned the other day to someone on this list that you may have to set a supervisor password in the BIOS before you can change the UEFI and/or secureboot setting. Give that a try and see if it helps. Just remember to removed the supervisor password if you don't really want it long term. -- Cheers!

I have a rather depressing variety of mechanical keyboards, including a couple IBM Model Ms. To clarify my biases, I LOVE the feel of the IBM Model M keys. My keyboard at work is a Kinesis Advantage with their standard Cherry Brown switches. I think the Advantage's physical layout is about the best that's available in any keyboard right now: vertical columns (rather than slanted columns we still persist in copying from typewriters: not only is it no longer necessary, it's actually ergonomically bad), dished hand areas to match differences in finger length, and a split between the hands. I have three Kinesis Advantages. As mentioned, one has the original Cherry Browns. They're okay. I have a second that I refitted with Cherry Blues: that's the one I use at home. That's my idea of a great keyboard. The Cherry Blues are about as close as you'll get to the behaviour of the IBM Model M buckling spring keys (short of buying one of the Unicomp keyboards that actually have buckling springs). They have a strong tactile click when the key activates. It's also audible: it's just as well I live alone, as the Blues are notoriously loud and irritate the crap out of people nearby (just like the Model M). I refitted the third Kinesis Advantage with Cherry Clears. Initially they feel quite similar to the Browns, but they're stiffer: you don't notice it immediately, but after a couple hours of typing, I found it genuinely tiring to use. I don't use it much. I highly recommend the Cherry Blues to non-gamers. Just be prepared for the noise. The bigger Canada Computers stores usually have several keyboards with different Cherry switches out for testing. If anyone has questions about any of this, feel free to contact me off-list: I've been a bit of a keyboard wonk for a couple decades. -- Giles http://www.gilesorr.com/ gilesorr(a)gmail.com

Processing a binary file with a shell script
by Ansar Mohammed 10 Aug '15

10 Aug '15

Hello All, I am writing a bourne shell script, to read a binary file as input and take action depending on the contents of the file. The file is a mixture of ASCII and binary codes (such as ASCII filed lengths and flags). I have the processing already done in C. I would like to convert it to a bourne shell. Does anyone have any suggestions on what combination of tools I may be able to use?

Ubuntu with all-desktops-in-one ?
by William Park 10 Aug '15

10 Aug '15

Hi all, With Debian, you can install all desktops (kde, gnome, xfce, etc) from ISO at first, and then choose which the desktop when you log in via gdm/kdm. Is there a version for Ubuntu which allows you to do that? Right now, you have to choose/install different ISO for each desktop. Or, do I have to start with "minimal install", and then install all the desktops afterwards? But, I don't know if gdm/kdm will pick up the desktops. -- William

On how to disable high security UEFI in > windows 8 & 8.1 computers. > Cheers Abby Hi Abby, Googling UEFI BIOS disable should bring up quite a few links. Unfortunately, there is no standardized way of disabling the UEFI and switching back to using BIOS. In general, there are basically two challenges: 1) getting the attention of the firmware that runs on initial startup before the operating system (Windows or Linux) gets to start, and 2) navigating the setup menus to disable the UEFI. Doing the first usually requires you to press or hold down a particular key at a particular time, which one and when depends upon the manufacturer. Depending upon a number of factors, you may or may not see a splash screen providing a hint while booting. Knowing the make and model of your computer can also help to determine this. Most computer manufacturers should have user documentation in PDF format that you can download from their web site. I hope that this helps. --- Talk Mailing List talk(a)gtalug.org http://gtalug.org/mailman/listinfo/talk
