another unique store gone: Above All Electronic Surplus
by Stewart C. Russell 17 Dec '19

17 Dec '19

Losing Active Surplus a few years back was bad, but this one seems worse: long-established electronic surplus/weird stuff/junk store Above All Electronic Surplus (635 Bloor W, at Euclid) is closed. I went by today and the windows were papered over and a For Lease sign was on the front. Steve, the owner, was inside tidying up, but the door was locked. Above All was where I went for the off-the-wall retro stuff I knew no-one else would carry. Appletalk cables? Bulk PC reset buttons (some still marked Turbo XT)? SCSI interfaces? Mac Classic RAM? These are all things I found at Above All. Above All has moved before. Let's hope this is the case again. cheers, Stewart

If you already have a topic in mind please send an email <a href="mailto:speakers@gtalug.org">speakers(a)gtalug.org</a> to be added to the list of scheduled talks. If you would like to give a talk during the meeting, all you have to do is write your name on a post-it and stick it on the whiteboard in the front of the room. When your talk gets selected, you will have five to present your idea, then five minutes of audience questions. ### Five Minute Talks ## Location George Vari Engineering and Computing Centre 245 Church Street, Room 203 Ryerson University <https://goo.gl/maps/16oJ2> <https://www.openstreetmap.org/way/23447525> ## Schedule * 6:00 pm - Please discuss on the general mailing list (i.e. <talk(a)gtalug.org>) where you want to go for dinner. * 7:30 pm - Meeting and presentation. * 9:00 pm - After each meeting, a group of GTALUGers move to The Imperial Pub (54 Dundas St East) for refreshments and more socialising. # Code of Conduct We want a productive happy community that can welcome new ideas, improve every process every year, and foster collaboration between individuals with differing needs, interests and skills. We gain strength from diversity, and actively seek participation from those who enhance it. This code of conduct exists to ensure that diverse groups collaborate to mutual advantage and enjoyment. We will challenge prejudice that could jeopardise the participation of any person in the community. The Code of Conduct governs how we behave in public or in private whenever the Linux community will be judged by our actions. We expect it to be honoured by everyone who represents the community officially or informally, claims affiliation or participates directly. It applies to activities online or offline. We invite anybody to participate. Our community is open. Please read more about the GTALUG Code of Conduct here: <https://gtalug.org/about/code-of-conduct/>.

Harmony Place is looking for volunteer developers/designers
by David Collier-Brown 14 Dec '19

14 Dec '19

A friend of mine, Emily Yuen, volunteers there helping adults with multiple disabilities, and because she's a retired programmer, was asked about exploring the idea of an IT person to write some apps, to facilitate some of the things they do. It's a bit of an open-ended question, including what one can do as well as how, perhaps starting with apps on ipads and/or the web. If you're interested, send her email at Emily Yuen <emily.w.yuen(a)gmail.com> and CC me. --dave -- David Collier-Brown, | Always do right. This will gratify System Programmer and Author | some people and astonish the rest davecb(a)spamcop.net | -- Mark Twain

Toolchain Selection
by Nicholas Krause 13 Dec '19

13 Dec '19

Greetings, Lennart was asking but LLVM does have a c library implementation, linker and debugger currently. While most inexperienced toolchain developers or people building one assume you have to use all GCC or LLVM excluding the c library that's not the case. A lot of people use lld, LLVM's linker with GCC due to it being much faster. For a traditional toolchain you require: 1. Compiler 2. Linker 3. C Library 4. Kernel Headers 5. Probably a Debugger Therefore you can select or take what you want from each of 1,2,3,5 from either LLVM or GCC. There has been lots of work on the LLVM and GCC sides to make sure it works well and still is. If your going to ask me questions please CC the list so others can get the info as well, Nick

How much do you know about how linux executes binaries?
by lsorense＠csclub.uwaterloo.ca 13 Dec '19

13 Dec '19

Someone at work just made a slight mistake: root@ECA:~# cd /var root@ECA:/var# mv core.* /* [clearly that trailing * was not meant to be there] [bunch of errors about target already existing] root@ECA:/var# ls -bash: /bin/ls: No such file or directory root@ECA:/var# So what do you do now? I was able to fix it in about 5 minutes without using anything other than what was on the running system? Interesting little problem. The original state of the system was: root@ECA:/var# ls -l / drwxr-xr-x 2 root root 4096 Dec 9 11:47 bin drwxr-xr-x 2 root root 4096 Dec 6 11:16 boot drwxr-xr-x 10 root root 2340 Dec 6 11:18 dev drwxr-xr-x 46 root root 4096 Dec 9 11:48 etc drwxr-xr-x 6 root root 4096 Dec 5 12:09 home lrwxrwxrwx 1 root root 10 Dec 5 12:09 init -> /sbin/init drwxr-xr-x 4 root root 4096 Dec 5 12:09 lib drwxr-xr-x 5 root root 4096 Dec 5 12:09 lib64 drwx------ 2 root root 4096 Dec 5 12:09 lost+found drwxr-xr-x 2 root root 4096 Nov 19 10:07 media drwxr-xr-x 4 root root 4096 Dec 5 12:09 mnt drwxrwxrwx 6 root root 4096 Dec 5 12:24 opt drwxr-xr-x 3 root root 4096 Dec 5 12:09 persistdata drwxr-xr-x 5 root root 4096 May 25 2018 persistent dr-xr-xr-x 473 root root 0 Dec 6 11:17 proc drwxr-xr-x 5 root root 4096 Dec 9 11:38 root drwxr-xr-x 12 root root 780 Dec 6 11:18 run drwxr-xr-x 2 root root 4096 Dec 9 11:47 sbin dr-xr-xr-x 11 root root 0 Dec 6 11:17 sys drwxrwxrwt 8 root root 400 Dec 11 12:14 tmp drwxr-xr-x 12 root root 4096 Dec 5 12:09 usr drwxr-xr-x 15 root root 4096 Dec 5 12:15 var -- Len Sorensen

Discussions about Compiler Technologies
by Nicholas Krause 11 Dec '19

11 Dec '19

Greetings All, Hopefully you learned a little yesterday if you were there. I've mentioned this to Alex but the group seems to have a interest in certain parts of compilers and other related technologies. Normally I would prefer Q and As or walking through code directly as its far more interesting to people them just slides. I'm opening it up for discussion here about what the group is interested in. Mostly I got frontends including clang,Rust e.t.c., JIT vs compiler time and what is better when and GPUs in particular, compiler backends as related to instruction cost selection and other things. Have a good holidays and new year, Nick

Graphics cards - - - too much 'joy'
by o1bigtenor 10 Dec '19

10 Dec '19

Greetings I had a system built in Jan 2012 which included an Asus P9X79 mobo and 3 Geforce 570 video cards where I've been running a variant of Debian, usually testing, ever since. I ran using 2 of those cards utilizing first fully proprietary drivers and then a couple years ago I shifted to the debian version of the same. This last spring 2 of the 3 cards failed and nvidia retired support for the cards in their current drivers so I went to using nouveau for my graphic card driver. I purchased a Radeon RX570 graphics card and a week ago swapped out Nvidia 570 card. I was unable to even get the system to post on first try (I had all 4 monitors plugged into the gpu). Went back to the Nvidia card and the system is working just fine. Tried the Radeon RX570 again this time only plugging in 1 monitor - - - - the gpu light do come on but I can't tell if much further is happening. I called my purchase point and they requested I send it back to them. They are now telling me that the card is working well on their M$ test machine. I'm not sure what to do or what I did wrong in my install attempt. Any ideas? TIA
