Tues Sept 13th, MIT room E51-376 7.pm - Brendan Gregg's FlameGraphs (Bill Ricker, moderator) [image: cpu-mysql-crop-250.png] Brendan Gregg's FlameGraph profiler visualizationI stumbled on a link to a set of posts and hand-drawn 'zines' about Linux debugging and 'doing' software at jvns.ca/zines/ . The Linux Debugging zine includes several 'old friend' tools (which gives me confidence in this person's opinions) and also included new or new to me options and tools, and specifically enthused over Brendan Gregg's invention FlameGraphs. Brendan invented these to make sense of profile stack samples of MySql, which produced so much data that he had to invent a new way to visualize ... with Perl, naturally. Tim Bunce has bundled and enhanced FlameGraphs into CPAN NYTProf, but it's usable with and profiler capturing stack frames. Works with any profiler giving full stack traces with symbols ( Dtrace, perf, SystemTrap, OS X Instroments, Xperf.exe, NYTProf for Perl ). We will watch a video by the author and play with the source code.
We will *not* be staying late since I need to be elsewhere by 10pm. I may roll-tape a little earlier than usual to make sure we have time to choose between exploring the code or web extras. - Tech Meetings are held on the 2nd Tuesday of every month at MIT building E51, Sloan School Tang Center [not the other Tang building!] nearer to Kendall Sq than Mass Ave. (directions <http://boston-pm.wikispaces.com/MIT+Directions>). - Talk begins at 7:30. - Refreshments in the hallway prior. - *RSVP for count* encouraged but not required, to bill.n1...@gmail.com or Boston-PM list <http://boston-pm.wikispaces.com/Mailing+Lists>, by 4pm Tuesday. (*NOTE: **Note NO NOVEMBER tech meeting - 2nd Tuesday in November in a Leap year is Election Day - I presume most people will be watching a different channel that night.)* Future - Winter/Spring reservations *If you have a demo or talk idea, please, when would you like to present? Doesn't need to fill the full time.* Confirmed room assignments courtesy of MIT *Tentative Confirmed*: (subject to academic schedule change) Tues Oct 11th, room E51-376 ** NOV ** (2nd Tuesday in November in a Leap year is Election Day, i think we'll skip, that'll be a busy news night for folks. Worse competition than World Series or Olympics. We can pick an alternate date or do a weekend social or off-week social.)
