When I was in California last week I gave a short talk at the NGINX User Summit on ngx_pagespeed. While people often post the slides from talks like this, my slides are terse enough that I should probably include some explanation:
A major reason to use NGINX is because it's fast. NGINX really is very fast at what it does: moving bytes to the client. But that's not the only thing, or even the main thing, that makes for a fast experience from the perspective of a visitor to your site. Instead it's a matter of what you put on your site, how many bytes that is, how many round trips the client needs in order to download it, and how much of that work the browser can do in parallel. more...
Rehearsing we wanted to send recordings to someone to get their feedback, so one of us got out a macbook and recorded us playing a set in Garage Band. Listening back, it sounded terrible. The levels were fine, no digital clipping, and Garage Band said it wasn't applying any effects, but it was just all weird and phasey sounding. Then I tried my mine, in Audacity, and it was all wrong in exactly the same way. We were about ready to give up on the macs and use a phone instead when we found the magic setting:
This weekend someone asked me what sort of things the Free Raisins do instead of playing the melody and chords through the same way each time. How do we interact with the dancers? How do we play with the energy level? How do we change what we're playing to better fit the dance? How do we add variety?
While that's a big question, and I could give long text answers about what we're trying to do and what effect we're going for, it might be clearer to work through an example. Here's a video of us playing at the Dance Flurry:
If you're interested in the answers to the questions above, start it playing and follow along on the transcript below. There are a lot of little things one of us does that's I've skipped, but this should have most of the big things. more...
Sometimes we hear about athletes trying to lose:
Norio Sasaki, the coach of the Japanese women's soccer team, fielded a weaker squad against South Africa and played for a tie as the country tried to sidestep a victory that would have meant a long trip for a match with tougher opponents.You'll notice, however, that they're not really trying their hardest to lose. When you have your stronger players stay on the bench but still keep going for goals you're balancing your desire to lose against your need to look to the judges like you're still trying to win. But what if we relax the second requirement to only apply to intentional resignations, forfeitures, and fouls? What if we had a game where both sides were trying their absolute hardest to make the other side win? more...
The badminton teams also may have been trying to lose so they could avoid more difficult opponents in the quarterfinals, when their competition also moves to a knockout stage.
Attendance at dances fluctuates for all sorts of reasons, which means there's a lot of variability in how much money comes in. Dances usually handle this variability somewhere between two extremes:
The quality of statistics post ended up generating a lot of discussion, mostly not about the data I collected in the post. Which makes me sad, because I put a bunch of work into that (graphs!), but the discussion was interesting enough that I don't mind. The jumping-off point was a comment by Arthur:
That post is exactly my problem with Scott. He seems to honestly think that it's a worthwhile use of his time, energy and mental effort to download evil people's evil worldviews into his mind and try to analytically debate them with statistics and cost-benefit analyses.Scott has now responded, but I think his post is long enough that people who don't find his writing enjoyable for itself may not get through all of it.  So here's an imaginary discussion, what I think you might get if versions of Scott and Arthur that valued being very terse sat down to talk.  more...
He gets *mad* at people whom he detachedly intellectually agrees with but who are willing to back up their beliefs with war and fire rather than pussyfooting around with debate-team nonsense.
