 Over the past year, I've experimented extensively with cold brew at home, spending too much on equipment and gadgets. This post is a distillation of my learnings.
 
 # Equipment
-I was extremely dissatisfied with the Bruer device that shows up in a lot of search results; clean-up is easy, but setting the drip rate is fussy and repeatable brew results are almost impossible. Instead, I recommend the [OXO cold brew tower](https://www.oxo.com/cold-brew-coffee-maker). $50 is not bank-breaking, and the hassle-free clean up is well worth it.

 A kitchen scale is a requirement as well; I'm reasonably satisfied with [OXO's 5-pound scale](https://www.oxo.com/products/preparing/measuring/5lb-food-scale-w-pull-out-display#black), but I find myself wanting a higher precision readout when I'm mixing drinks.

 The quantities might seem strange, but are designed to sum up to 12 oz. The ratios of milk and water can be tweaked to taste, but I find more than 1/2 an ounce of cream makes the drink too rich, and less than 5 oz of milk makes the drink more watery than I like.

-Benchmark data generally isn't interesting in isolation; once we have one data set, we usually gather a second set of data against which the first is compared. Reporting the second result as a percentage of the first result isn't sufficient if we're rigorous and report results with [confidence intervals](https://www.brainvitamins.net/blog/confidence-intervals-for-benchmarks/); we need a more nuanced approach.

 Let's suppose we run a benchmark 5 times and record the results, then fix a performance bug and gather a second set of data to measure the improvement. The best  intuition about performance gains is given by scores and confidence intervals that are [normalized](https://en.wikipedia.org/wiki/Normalization_(statistics)) using our baseline geomean score:

 Computing the averages of averages is not always statistically sound, so it may seem incorrect to take the average FPS from each iteration of a benchmark and average them together. In this case we can confidently say that each average has [equal weight](https://math.stackexchange.com/questions/95909/why-is-an-average-of-an-average-usually-incorrect/95912#95912); if not, we need a different benchmark!

-Steam downloads the Windows version of a Proton-enabled app, but still stores files in the familiar `~/.steam/steam/steamapps/common/[appname]` directory. On first launch, Proton provisions a Wine prefix (created in `~/.steam/steam/steamapps/compatdata/[appid]` by default) that holds pertinent state data and a basic Windows filesystem in `$WINEPREFIX/pfx/drive_c`. This filesystem is presented to the app as its root Windows filesystem.

 Windows applications frequently have additional dependencies like the [Visual C++ Runtime Redistributables](https://support.microsoft.com/en-us/help/2977003/the-latest-supported-visual-c-downloads), and apps may require specific workarounds to run well in Wine environments. Many of these concerns are managed by the app's install script (usually `~/.steam/steam/steamapps/common/[appname]/installscript.vdf`), but `~/.steam/steam/legacycompat/iscriptevaluator.exe` also runs inside the Wine environment during initial provisioning and appears to manage Proton-specific dependencies and tweaks.

 * A sharp razor can shave arm hair without lather or discomfort. If the razor pulls on the hair or fails to cut it, it's time to sharpen the razor.
 * Make sure to use the sharpening tools properly (read the instructions). I tend to use too little water on my waterstone; it should be nicely soaked
