Speaking on PostgreSQL

I’m doing a talk on Sept 13th at GTALUG GTALUG Sept 2016 where I’ll be talking on things new in PostgreSQL 9.5 (released in January 2016) and upcoming in 9.6.

Here’s a copy of the material…
PostgreSQL New Stuff

Spamalicious times

Hmmph. Google sent me a “nastygram” indicating that one of my blog entries had something suggestive of content injection.

I poked around, and it was by no means evident that it was really so. The one suspicious posting was http://linuxdatabases.info/blog/?p=99 which legitimately has some stuff that looks like labels, as it contains a bunch of sample SQL code. I’m suspicious that they’re accounting that as being evil…

But it pointed me at a couple of mostly-irritating things…

  1. I haven’t generated a blog entry since 2013. Well, I’m not actually hugely worried about that.
  2. I reviewed proposed response posts, since, probably about 2013. Wow, oh wow, was that ever spam-filled. Literally several thousand attempts to get me to publish various and sundry advertising links. It’s seriously a pain to get rid of them all, as I could only trim out about 150 at a time. And hopefully there weren’t many “real” proposed postings; it’s almost certain I’ll have thrown those away. (Of course, proposed postings about things I said in 2013… How relevant could it still be???)

Nexus 7 on CyanogenMod

At last…

I had been lazy, leaving all alone.

In February, I figured I was heading off for a chunk of the month on a cruise, hence wanting tablet for multimedia, but without network, so it was timely not to spend time fiddling with configuration with possible risk of mussing such up.

Alas, the OTA upgrade to JellyBean did a certain chunk of mussing…  It busted SuperUser access, thereby breaking Titanium Backup.  No backups went properly since :-( .

So, today seemed right timing.  I wanted backup, and needed root, the latter looking like a fight.  Ah well, go for gusto, see what we get without it…

I had to upgrade adb to support latest Android…   Got Clockwork Recovery in place, and zip files for CM10.1 and Google Apps…

The last backup was Feb 16, but happily the files still remained after fresh CM10.1 installation, so I could do a good chunk of recovery of apps, and in plenty of cases, this was basically network configuration, so apps would update their own data upon startup.  Sweet!

Superuser is nicely integrated into CM10, also sweet, no extra installation process.

I’ll need to reconfigure the launcher, due to the shift from ADW (I had a license) to built-in Trebuchet on CM10, but that seems like the “worst” irritation, and one I can well live with.

I’m not sure I can readily identify big differences between stock Android and CM10, but there are nice small creature comforts my CM10 phone has gotten me used to, like a quick “turn on/off WiFi” directly on notification screens.  Small but I like it.

Mailman subscriber lists

As part of “due diligence” for some mailing lists I am involved with (for Slony, see slony-backups ), I discovered the need to dump out Mailman mailing list subscribers.

There is a script to do this, written in Python, mentioned on the Mailman wiki, accessible as mailman-subscribers.py

I’d kind of rather have something a bit more version-tracked, so I poked around at GitHub, and found larsks / mailman-subscribers

That was a little out of date; the last code was from a couple of years ago, so I forked, updated to the latest, and suggested that “larsks” pull it, which he did, quite quickly.

The “kudos” bit is that I noticed a bit of a blemish, in that the mailing list password was required to be on the command line, thereby making it visible to anyone with access to /usr/bin/ps on one’s system. I submitted a feature request, and Lars was so kind as to have this feature added so quickly that by the time I had the prototype of my Slony “subscriber backup” script working, I immediately needed to change it to make use of the lovely new password-in-file feature. Nice!

Installing git-annex from Debian unstable

Installing git-annex from unstable

I happen to be a supporter of Joey Hess’ Git Annex Kickstarter project; no big bucks, but it seemed a good thing to help out.

I got in the stickers, that were my “project reward,” and figured I should start playing with the new results. I’m particularly keen on the planned Android client, but I should make some use of it before that comes available.

There’s good news, and bad news:

Good news
He has added in an assistant to provide interactive help in setting up repositories. It’s included in debian unstable, in a version released September 24th.
Bad news
I generally prefer using packages from debian testing, and it has a version released July 24th, well before any of this, and without any of Joey’s recent enhancements.

Fortunately, drawing in the September/~unstable~ version isn’t too terribly difficult. My /etc/apt/preferences.d/simple configuration has Pin-Priority values that prefer stable over testing, testing over unstable, and unstable over experimental (where enormous potential for breakage lies!).

As a consequence, installing the testing version is pretty easy, albeit involving an option I had to go looking for:

root@cbbrowne:~# apt-get -t unstable install git-annex
... leads to loading ...
Get:1 http://ftp.us.debian.org/debian/ unstable/main git-annex amd64 3.20120924 [7,411 kB]

And, with a run of % git annex webapp, it’s up and running!
