Subject: [sf-perl] canceling july lightning talks
Message-ID: <CAFfgvXUjKH653Dvrd1DEA1gsGetxY-mxzD-mYTy7Qe8fk2=7YA@mail.gmail.com>

Hey gang-- I've decided to cancel the SF Perl meeting
for this month.  I was thinking about doing a round of
Lightning Talks, but I wasn't getting a lot of
volunteers this time, for whatever reason.  So, we'll
try it again some other time.

One more time: there's no SF Perl meeting for July.

Subject: [sf-perl] July 26th Meeting is on: Better Service Monitoring
	Through Histograms
Message-ID: <CAFfgvXUFRhw9j6Umt4wx-qktnM6WhaH2D4XrwD4jHAb_b2t0yQ@mail.gmail.com>

As you've probably seen from the meetup.com site, the July 26th
meeting is back on, with a talk from Fred on "Better Service
Monitoring Through Histograms":

Fred Moyer will introduce us to statistical based service monitoring.
If you've used something like Nagios, Graphite, or Zabbix to monitor
your systems, you're probably familiar with threshold based alerting.
Specifically, that it often results in you waking up in the middle of
the night for false positives. This talk will show you how to
implement quantile based service monitoring with histograms, so that
you can understand how your service is actually doing, rather than
just guessing based on metric averages.


This looks like a good one on a subject of pretty broad appeal. Help
spread the word...

By the way, is anyone still seeing any trouble with the video of last
month's talk?

https://archive.org/details/LearningGoForPerlProgrammers

It seems to be working for me now, but I have had some trouble with
in-browser playback at least with some versions of Firefox on Linux.

(The ogv file always seems to work, though, and downloading the files
always works...).

Subject: [sf-perl] Larry Wall interview on slashdot
Message-ID: <CAFfgvXXHwpPUbRNB8ZuD005eRt0VT81Z6mHoJVcx671Jr81NjQ@mail.gmail.com>

There's a Larry Wall interview up on slashdot that's definitely
worth a look:

https://developers.slashdot.org/story/16/07/14/1349207/the-slashdot-interview-with-larry-wall

I liked the remarks on unicode:

  "One thing we do to fight cultural imperialism with Perl 6 is
  to treat any grapheme as if it were a precomposed character,
  whether or not the Unicode Consortium happens to have defined
  one under NFC yet. If there's no precomposed codepoint, we
  simply make one up temporarily. So we get O(1) string indexing
  based on what the user thinks is their language. (Even for
  characters outside the BMP. Lots of current languages force you
  to consider an emoji or a cuneiform character as a combination
  of two codepoints. Yuck! I mean, XP. Well, I really mean
  U+1F61D, FACE WITH STUCK-OUT TONGUE AND TIGHTLY-CLOSED
  EYES. But you'll have to imagine it for now, because Slashdot
  is not written in Perl 6. (Yet.)"


Oh and by the way:

  "You wanna write Inf as that funny sideways 8 character, or
  write pi with the Greek letter, go right ahead. You wanna write
  your powers with superscripts instead of **, you can do that
  too. Yes, we're insane, but you're gonna love it...as soon as
  you figure out how to type it."

There's an easy way of typing unicode characters in emacs:

  C-x 8 <return> <hex codepoint> <return>

I would guess there are even easier ways, but that one always works.

Fred Moyer's is doing a presentation tonight over at craigslist
tonight on "Better Service Monitoring Through Histograms".  This one
has a wider appeal than our usual perl-centric material, so spread the
word to the sysadmin-types in your life... RSVPs close at 3pm this
afternoon though, so hurry-hurry etc...

An URL for slides or video would be terrific?

Sure, we're working on it.  Should be out today or tomorrow.

I've posted the slides from the talk here on slideshare -

Thanks to everyone who came out for the talk. Good math discussions after,
I learned a couple new things.

I'm glad we've got the slides, it turns out we had some bad technical
difficulties with the video.

This really is too bad: Fred's right, the Q/A session covered some
interesting ground...

Looked through the slides. There's a concept from manufacturing that
comes to mind, "Statistical process control,"
https://en.wikipedia.org/wiki/Statistical_process_control that lays
out a few other heuristics for warning about out-of-control processes.
The methods you found from experience are more appropriate than their
general recommendations, just thought I'd paste the link for anyone
interested in the theory.
