PyCon 2015 was full of ♥ ✅ ♩ ☀ ♕ ⛵ ⛱. Here is a mostly-ordered list of my personal highlights among the bajillion talks (youtube channel, pyvideo page):

• Glyph - The Ethical Consequences Of Our Collective Activities, Glyph exploring the lack of ethics standards for programmers, as opposed to e.g. doctors or lawyers.
• Kate Heddleston - How our engineering environments are killing diversity (and how we can fix it) and Keynote - Jacob Kaplan-Moss, best talks ever on encouraging diversity in the tech scene.
• Gary Bernhardt's closing keynote on beliefs was excellent! Where is the video?!
• Dan Callahan - My Python's a little Rust-y, thanks Dan for this newbie-accessible introduction of what makes Rust Rust.
• Dan Callahan - Fire your supervisord running Python apps on CoreOS, super digest overview of some new sexy deployment practices.
• Smart services & smart clients: How micro-services change the way you build and deploy code, great non-bullshitish talk with actual practices & code on microservices.
• Raymond Hettinger - Beyond PEP 8 -- Best practices for beautiful intelligible code, Hettinger reminding us to not be distracted by the little things and focus on the important stuff.
• Tom Eastman - Serialization formats are not toys, exploring a little-known security concern.
• Thomas Ballinger - Terminal whispering, fun quirky presentation on the good'ol'terminal.
• Ying Li - Where in your RAM is "python san_diego.py"?, both fun and deep talk on python-based memory forensics and kernel stuff.
• Andrew Godwin - What can programmers learn from pilots?, sane analogies.
• Ryan Kelly - PyPy.js: What? How? Why?, pretty crazy stuff.
• Curtis Lassam - Hash Functions and You: Partners in Freedom, neatly-illustrated talk on hashing. Learned about bloom filters.
• Allison Kaptur - Bytes in the Machine: Inside the CPython interpreter and Allison Kaptur - Exploring is never boring: understanding CPython without reading the code, two excellent dives into CPython.
• Andrew Montalenti - streamparse: real-time streams with Python and Apache Storm, uuuh was too much for me as an introduction to Storm, but makes me want to play with it.
• Josh Triplett - Porting Python to run without an OS, wat.

Props to the organizers and volunteers! On to Portland next year.
