Neat thing seen... https://mzucker.github.io/2016/09/20/noteshrink.html

I didn't get quite as nice results on a sample that I tried, but that may be the fault of my handwriting! :-) It did pretty massively shrink the image files, without any loss of readability, to be sure.
I wrote a program to clean up scans of handwritten notes while simultaneously reducing file size.

I would so, so, so love to see more of this.

Sizing shot of Pine64, complete with (top left) the extra switch included in the box that is evidently intended to be soldered in as a reset switch.

Unsure as yet. As it's a kick starter, timing of availability was never plannable.

Seems likely capable as a media server, but my Zotac covers that well.

Cool idea is that it runs libreoffice, so make it a real portable carryable. Need for that is sporadic, e.g. LUG meetings.

Maybe it replaces an elderly server?

You might want to rotate that picture.

One very interesting observation fell out in the #slony  development meeting...  There are cases where users have attempted to migrate from Slony to built-in replication, and headed back, and it expresses a significant case where built-in replication has a big hole...

Built-in replication (and the mechanisms being built atop logical decoding http://www.postgresql.org/docs/9.4/static/logicaldecoding.html have the same issue) has a problem where the database is very busy, having a LOT of WAL updates, but the data that needs to be replicated is a small subset.

In that case, you have a LOT of WAL files that need to be both processed and kept (needs to be kept long enough to ensure data has reached other replicas), and perhaps transported.

I know we had a case at work where we wanted to use WAL replication for a data warehouse system, and found that the nightly re-indexing of certain tables led to a lot more gigabytes of WAL files heading downstream than our network links would permit.

But to not digress further, if the database is otherwise-busy, there will be a LOT of WAL data, and if the updates that need to be replicated are minor in volume, WAL-based capture is turning out to be impractical.  Cheaper to pay for some extra triggers and logging of data (as is done by Slony).

I have been messing around a bit more with my Pine64 (64 bit quad-core ARM).

After installing a later edition of Debian, it seems to now be surviving reboots OK, as opposed to falling into some sort of "black screen of death" (which is imagined to be some sort of need to run fsck or such; it was stopping before the kernel gets to any interesting work).

My discovery of today is that it's able to run Kodi, complete with sound and graphics, however it's not got any optimized codecs, so it won't play video. The other not-totally-fun bit was that the Kodi UI was nearly glacially slow. I was able to get it to recognize and mount content via NFS from the neighbouring box, but it was very slow responding to input. (Seemed to recognize files on NFS quickly enough, mind you...)

I'm not quite sure what I ought to have it run.

I'll bet I ought to make it a Postgres buildfarm animal... I hope I have enough storage (11GB left on a 16GB MicroSD card).

NetBSD of course. :-)

If you read this as if it's serious, and not satire, it's pretty creepy how true it seems.  In fact, I wonder if there's not strategy in the Tim Hortons boardroom to this end...
HAMILTON, ON - International restaurant chain Tim Hortons is celebrating 50 years of instilling and manipulating contrived patriotic sentiment in Cana...

An amazing, almost Kafa-esque story about how one company’s carelessness has created aggravation for scads of innocent people. A service that associates Internet IP addresses with real world locations has a default answer for those IPs it can’t figure out.  A default location in the geographic center of the US… or the center of any state in question.  And hence, there are now over 600 million IP addresses associated with that default US coordinate. “If any of those IP addresses are used by a scammer, or a computer thief, or a suicidal person contacting a help line, MaxMind’s database places them at the same spot: 38.0000,-97.0000.” Which leads to one little farmhouse in Kansas and a world of trouble.  Others on the top default list have had police raids, death threats.  A Monty Python-level problem that can only be (and now is) solved by transparency. 
 
Because of good investigative journalism, the company has scurried to fix the problem and shift the default locations to the very middle of large lakes.  And Nessie is getting perturbed by strange calls in the night.

I just got a Pine64 SBC via a KickStarter (https://www.kickstarter.com/projects/pine64/pine-a64-first-15-64-bit-single-board-super-comput); this is a Quadcore 64 bit ARM running Cortex A53, 2GB RAM, HDMI output, generally quite a lot more capable than even the latest Raspberry Pi.
It came in last night, and was soon running Debian. This screenshot was germaine for me to configure my DHCP server to be aware of it ;-)

Hey Chris, I got mine yesterday; where did you get Debian SD card image?

OK, so the PanAm games are keen on "being a success," but have forbidden interested people from linking to it to do things like saying "Exciting things taking place at PanAm Games in Toronto!  Look...  Here...  Um, oops, they tell me that I'm not licensed to direct you to their web site.  Sorry about that, no sportsing taking place here, go on with your non-PanAm-y business..."
Maybe it’s a case of overzealous lawyering, but the legalese on the official Pan Am Games website states that no one is allowed to link to it without written permission. “Links to this Site are not permitted except with the written consent of TO2015™.

…or perhaps people will criticize, yet avoid linking, thus diminishing their chances of success.

Pupusas are wonderful, steaks are surprisingly good.

Has long been THE science fiction (and fantasy) bookstore of Toronto. Friendly, knowledgeable staff, and considerable selection. Sadly, SF has shrunk, as a genre, so there's less excellent stuff than there used to be. This is of course not attributable to any one store. (More to policies at American book chains such as Barnes & Noble and Amazon, but that is a rather deeper tale...)
