Regular Expression Engine Comparison Chart

Many different applications claim to support regular expressions. But what does that even mean?

Well there are lots of different regular expression engines, and they all have different feature sets and different time-space efficiencies.

OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

brew install flac ffmpeg cuetools  # ставим нужные пакеты
# скачиваем cuetag.sh скрипт, например отсюда https://github.com/gumayunov/split-cue/blob/master/cuetag

ffmpeg -i 1.ape 1.flac # конвертируем во flac, так как libmac для APE не ставится на osx
cuebreakpoints 1.cue | shnsplit -o flac 1.flac #нарезаем на треки
cuetag 1.cue split-track*.flac #прописываем тэги (cuetag.sh ставится отдельно отдельно)

#конвертируем в ALAC
for f in split-track*.flac

Running Hashcat on Google Cloud's GPU-based VMs

In February 2017, Google announced the availability GPU-based VMs. I spun up a few of these instances, and ran some benchmarks. Along the way, I wrote down the steps taken to provision these VM instances, and install relevant drivers.

Update April 2019: Updated instructions to use instances with the Tesla T4 GPUs.

Using a Reverse Proxy for Rapid Prototyping

Note: This will be a contrived example, but hopefully illustrates some real-world trade-offs.

Example scenario: Suppose you're an independent web developer, and a client asks you to prototype a redesign of their website header. You'll be paid for your time, and if the client likes it, you'll be hired to do the full implementation. Your incentive is to show the client a quick, functional demo of the updated header. The problem is that quick and functional tend to be mutually-exclusive.

At One Extreme: Do It Fast
