classes of x86 performance
by D. Hugh Redelmeier 01 Jul '16

01 Jul '16

This is oriented to gamers but I think that it is interesting. It helps one answer the question: will an upgrade be worth the bother? <http://www.tomshardware.com/reviews/cpu-hierarchy,4312.html> [wandering elsewhere in the topic of upgrades] My last desktop upgrade (a couple of years ago) was from class 6 (Core 2 Quad Q6600) to class 1 (i7-4770). RAM capacity might also matter. In theory, my old desktop could have 8G of RAM but in fact it could not, so I installed 6G. My newer desktop should handle 32G but I only have 24G installed. SSD is so much zippier than HDD that it might be the first upgrade to consider. It seems to make a lot of difference with "modern" desktops like Gnome 3, Unity and Windows 8.x and 10. Make sure that you do backups.

Linux in the Park travel advisory
by Seneca Cunningham 28 Jun '16

28 Jun '16

I just noticed when this year's Linux in the Park is, and thought that I should pre-warn everyone about some routing issues surrounding July 23. Bloor will be closed between Lansdowne and Dufferin on July 23 (and 24) for the Big on Bloor Festival of Arts & Culture (http://bigonbloorfestival.com) As you might expect, Dufferin Station will correspondingly be busier than usual, and parking may be harder to find. College streetcars may be busses, and may also be affected by streetscaping-in-progress.

I wonder about grid security and whether or not a microgrid can be designed to repel all borders. That is, only allow links to trusted sources. The way things are headed in the IoT, perhaps power source monitoring will detect the harmonic characteristics of each user in a trusted cluster and when combined with the overall harmonics of the grid, this data can be used for quality control and billing, or even equity trading between users.

On a You put the word battery in quotes. Perhaps you mean a Rogers valve? I think that's how the patent names it. When I was a kid every corner store had a tube tester for DIY repairs.

How to repeat a char in a line? (on Windows)
by William Park 26 Jun '16

26 Jun '16

My brain is not working today... too hot. On Windows, how would you generate a text line with 480 of 'M' chars? I have to describe to other people how to do it on their Windows machine. So, I need simple generic way. I can't tell them to install BusyBox, Cygwin, Vim, or Python. :-) -- William

Ubuntu snap
by ted leslie 24 Jun '16

24 Jun '16

never heard of it until just stumbled across this: http://betanews.com/2016/06/14/ubuntu-snap-packages-linux-distros-fedora-ar… If its "good", doesn't it sort of defeat the strength of some distro's whose best attribute is package management, i.e. what folks claim of arch? Interesting to see what becomes of it (how much adoption). Stumbled across it, because its Mint 18 time soon!!!!!!! its like x-mas! -tl

Cheap 4k TV That Can be Used as a Monitor
by CLIFFORD ILKAY 24 Jun '16

24 Jun '16

Hello All, The Canadian Tire flyer has a 43" Seiki 4k UltraHD Smart TV (while quantities last - sorry no rainchecks, which usually means, forget about finding this anywhere) on sale at $399.99. I could not find this on the Seiki web site. They have a 42" model though <http://www.seiki.com/content/42-se42um-led-ultra-hdtv>. It will do 60Hz via HDMI 3. I do not know any video cards that will do that. Caveats * One year warranty. Who knows what their warranty support it like? * You will probably have to drive this at 30Hz. Hugh has a 39" Seiki that he drives at 30Hz. I do not think he finds the mouse lag objectionable. * The picture on the CT flyer is similar to the one on the Seiki web site but it is not identical. That and the 42" vs 43" discrepancy suggests the one at CT is different. * The legs on both models look just like the crappy Wasabi Mango monitor that I talked about a few weeks ago. LG uses the same legs. The 42" TV on the web site looks identical to the crappy Wasabi Mango. (Keyword frequency is important for search engine optimization.) -- Regards, Clifford Ilkay + 1 647-778-8696
