Ubuntu 16.04 proves even an LTS release can live at Linux’s bleeding edge
by Peter Reutemann 16 May '16

16 May '16

'A disappointing trend has become clear to Linux users in recent years. Whenever Canonical offers a new Ubuntu Long Term Support (LTS) release, it tends to be conservative in nature. (See our Ubuntu 14.04 review, which earned a "Missing the boat on big changes" headline.) Apparently no one wants to try to support a brand new, potentially buggy piece of code for half a decade. The last few Ubuntu releases haven't been LTS rollouts, yet Vivid Vervet (15.04) and Wily Werewolf (15.10) also short-changed users in the way of new features. So when Canonical officially released the latest Ubuntu LTS version (Ubuntu 16.04 or Xenial Xerus) this spring, similar expectations loomed. Frankly, this could potentially be the most boring Ubuntu release to date. Thankfully, perception hasn't matched reality this time around for Ubuntu users. Ubuntu 16.04 is in fact the most exciting release Canonical has put out in recent memory. And after using it for the last few weeks, this may even be the best release Canonical has presented to date.' -- source: http://arstechnica.com/information-technology/2016/05/ubuntu-16-04-proves-e… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Raspbian Linux OS Gets Major Update, Adds Bluetooth Support to Pi 3
by Peter Reutemann 14 May '16

14 May '16

"The Raspberry Pi 3 was launched with built-in chip for Bluetooth and Wi-Fi support, however, software support for Bluetooth was lacking until now. The drivers were there, but today's update to the Raspbian Linux distribution adds much-needed GUI tools to help you establish Bluetooth connections. Another cool addition is a new backup tool. There are other improvements as well including the mouse settings, and the ability to empty the wastebasket through right-clicking as seen below (yes, seriously). There is even a new shutdown dialog, something even casual users should notice." -- source: https://hardware.slashdot.org/story/16/05/13/1740218 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Could someone help with setting up a computer with linux
by Michelle 13 May '16

13 May '16

Hi, My name's Michelle. I've been using Linux on and off for the last few years. If this has not been sent to your LUG mailing list (if you have one) could you please send it to that or to all the people in your LUG please? I'm looking for someone who would help me set up a computer with linux on it. I had a Dell on which I set up Puppy with no problem whatsoever. The computer died and so then I took the puppy distro and the other disto I'd bought (can't remember what) and tried to install them on 2 older computers I had but it didn't work. I don't know why, maybe it was because one of the distros was on a stick and not compatible or maybe both computer hard drives were stuffed? After that I bought a mini-pc (I think it was supposed to run linux) but it didn't work at all. Then I bought a tablet but after a month or two it stopped working or pretty much? Stopped working. So I just used a phone for about a year and last year bought a brand new Toshiba laptop. The problem with this was two fold: 1. It was a laptop. 2. It was a Toshiba (oh how I hate Toshiba) I had known that not all computers were readily compatible with linux but after my easy experience with the Dell I wasn't too concerned. I bought two linux distros on different media and hoped/assumed? that something would work – it didn't. I bought another say 2 or 3 distros and managed to get the Mint to install on this Toshiba. It wasn't until after this annoying endeavor that I found out online that: - laptops are less compatible than desktops with linux and that - Toshiba out of the maybe top 6 or 8 computer manufacturers is consistantly about the least compatible with linux ( I HATE TOSHIBA) I don't happen to have a few spear thousand dollars sitting around to enable me to buy a computer and try and set it up with the distros I want, find it dosen't work, buy another computer, find it doesn't work, buy another and finally find one that works with the distros I want. So I am sending this message to basically all the Linux users groups in NZ and hoping someone can help me set up a computer with the two linux distros I want. I don't know how that would work. Maybe someone is about to buy a new computer and can try these distros before they put theirs on, maybe someone has a partition on their computer that is spare and can try it there, maybe they own a computer shop or work in a computer shop or at a university or polytech with computers or computer parts around. So for anyone who may be willing to help me here is what I would like: - a desktop (not the modern ones that are a computer plus other thing/s but just a computer - not a toshiba - Whonix to run on top of Qubes. Whonix is great for anonimity and Qubes is designed for security/safety. - I have a DrayTek vigor 120 modem. I connect it via DSL. When looking into whonix I read that it is complex to configure and setup, so I was hoping that you might have such a modem or access to one and set it up with whonix and then tell me how you did it. - I don't want the computer to come with wifi or bluetooth or any similar thing. I don't want it just not running, I don't want it there at all. - I'm wanting to install 3 old encyclopedias. I was reading about the new versions online and people were recommending old ones. I've bought Encarta 2004, 2001 and Encyclopaedia Britannica '98. To run them on I've bought Windows 98 second edition and Windows NT (first edition?). If you have or could borrow these windows OS could you see if you could get them running in whonix or qubes? - One or both of the encyclopedias need 2 DVD players so I'd like at least 2 DVD players with one being a recorder. - I'm not looking for a high end computer. As long as it will play youtube, that's fast enough. BUT I would appreciate hearing any recommendation about if I just add such and such for $100 or $150 it would go much faster. I'd like 500GB hard drive at least and I've been recommended to get 8GB RAM at least. I wouldn't buy the computer off you but rather if you could tell me what computer/computer parts worked, I'd pay up to $150 for the info. If 10 different people told me what worked of course I couldn't pay 10 different people $150. I am sending this to: the wlug, Glen Ogilvie at nelg(a)linuxsolutions.co.nz in Auckland, the Welly LUG through hugh(a)davenport.net.nz, nzlug(a)lists.nzoss.org.nz and Wellington LUG through jethro.carr(a)jethrocarr.com. If you know of any active LUG that I have missed or anyone else that might be willing to assist me could you please pass this onto them? My email is michelle400(a)orcon.net.nz. If this is posted to a mailing list (I've never used one before) and I don't reply in a week could you get back to me on my email? Thank you to anyone willing to help Michelle Gorringe.

BitKeeper Becomes Open-Source
by Lawrence D'Oliveiro 10 May '16

10 May '16

BitKeeper was the distributed version-control system that Linus Torvalds and the other kernel developers were using over a decade ago. It was a proprietary product, but the Linux folk were allowed use of it for no charge, under a licence that prohibited reverse-engineering, and that obligated them to uprade to newer versions with whatever new licence terms the company wanted to impose. It was a stoush over this reverse-engineering prohibition that led to BitMover giving notice it was cancelling this agreement, which in turn led to Torvalds creating Git. And the rest, as they say, is history. <http://phoronix.com/scan.php?page=news_item&px=BitKeeper-Open-Source>

Debian Dropping Support For Older CPUs
by Peter Reutemann 09 May '16

09 May '16

'The Debian project supports a wide range of hardware architectures, including 32-bit x86 CPUs. Changes are happening in Debian's development branches which will make older versions of the 32-bit architecture obsolete. Ben Hutchings provides the details: "Last year it was decided to increase the minimum CPU features for the i386 architecture to 686-class in the Stretch release cycle. This means dropping support for 586-class and hybrid 586/686 processors. (Support for 486-class processors was dropped, somewhat accidentally, in Squeeze.) This was implemented in the Linux kernel packages starting with Linux 4.3, which was uploaded to Unstable in December last year. In case you missed that change, GCC for i386 has recently been changed to target 686-class processors and is generating code that will crash on other processors. Any such systems still running Testing or Unstable will need to be switched to run Stable (Jessie)."' -- source: https://linux.slashdot.org/story/16/05/09/028259 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Leading-Edge Technology ... Or Not
by Lawrence D'Oliveiro 07 May '16

07 May '16

To service the McLaren F1 supercar, McLaren needs a Compaq LTE 5280 laptop which hasn’t been manufactured in about 20 years <http://www.theverge.com/2016/5/3/11576032/mclaren-f1-compaq-laptop-maintena…>. The laptop has a special CA (“Conditional-Access”) card, and "The CA card is an interface between the laptop software (which is DOS-based) and the car." .. the CA card was used as custom hardware as part of an integrated system for security and copy protection. In other words, this is part of a system to ensure that nobody but McLaren can access the car software. Their attempt at vendor lock-in has led to vendor lock-in being imposed on them.
