What I Wish I'd Known About Equity Before Joining A Unicorn

Disclaimer: This piece is written anonymously. The names of a few particular companies are mentioned, but as common examples only.

This is a short write-up on things that I wish I'd known and considered before joining a private company (aka startup, aka unicorn in some cases). I'm not trying to make the case that you should never join a private company, but the power imbalance between founder and employee is extreme, and that potential candidates would

Mobile Safari's 100% Height Dilemma

Whether you're developing a web application with native-ish UI, or just a simple modal popup overlay that covers the viewport, when it comes to making things work on iDevices in Mobile Safari, you're in for a decent amount of pain and suffering. Making something "100% height" is not as easy as it seems.

This post is a collection of Mobile Safari's gotchas and quirks on that topic, some with solutions and fixes, some without, in good parts pulled from various sources across the internets, to have it all in one place. Things discussed here apply to iOS8, iOS9 and iOS10.

The Disappearing Browser Chrome

Screen real estate on smartphones is limited, so Mobile Safari collapses the browser chrome (address bar and optional tab bar at the top, and tool bar at the bottom) when the user scrolls down. When you want to make something span exactly the height of the viewport, or pin something to the bottom of the screen, this can get tricky because the viewport changes size (or

"A little bit of slope makes up for a lot of y-intercept"

01/13/2012. From a lecture by Professor John Ousterhout at Stanford, class CS140

Here's today's thought for the weekend. A little bit of slope makes up for a lot of Y-intercept.

When should you use DateTime and when should you use Time?

It's a common misconception that [William Shakespeare][1] and [Miguel de Cervantes][2] died on the same day in history - so much so that UNESCO named April 23 as [World Book Day because of this fact][3]. However because England hadn't yet adopted [Gregorian Calendar Reform][4] (and wouldn't until [1752][5]) their deaths are actually 10 days apart. Since Ruby's Time class implements a [proleptic Gregorian calendar][6] and has no concept of calendar reform then there's no way to express this. This is where DateTime steps in:

>> shakespeare = DateTime.iso8601('1616-04-23', Date::ENGLAND)
=> Tue, 23 Apr 1616 00:00:00 +0000
>> cervantes = DateTime.iso8601('1616-04-23', Date::ITALY)
=> Sat, 23 Apr 1616 00:00:00 +0000

This requires the latest version of apktool.

apktool d $APK_PATH -o $OUTPUT_FOLDER

# Open the apktool.yml text file
# Alter the versionCode and versionName entries

# now rebuild!
apktool build $OUTPUT_FOLDER
