Weekend Reading — Adult supervision
@waxpancake how we shared cool GIFs in the 80s
This week, babies teach us how to write great error messages; it's Wiki vs README; we learn that most errors hide in error handling code; and how best to onboard engineers; we quack like a USB keyboard; we read the script to a missing Silicon Valley episode; and we learn to take better selfies.
Bye, Google Maps "Citymapper is what happens when you actually understand user experience." You can learn a lot from this side-by-side analysis.
How to write a great error message The best error message is the one that never shows up. But if you need to show a message, follow these guidelines.
Having a baby has really driven home how terrible it is when several issues result in the same error message
The Rise of Phone Reading It’s not the e-reader that will be driving future books sales, it’s the phone; how publishers are rethinking books for the small screen.
Feature Attachment Anonymous: A support group for people in software who can't let go of a feature bc 1 user asked for it. #UX
Tools of the Trade
Alex A text linter that catches gender favoring, polarising, race related, or other unequal phrasing.
apm install linter atom-linter-ales and type away.
Protected branches and required status checks Coming up in Github, protected branches that can't be force pushed, can't be deleted, and won't merge changes until they pass a status check (i.e. CI).
Some thoughts on documentation Wiki vs README:
tl;dr: people don't seem to trust Wiki content, nor explore it. They're also more nervous about editing Wiki content. Files imply: this is officially part of the project, and people feel comfortable sending a PR
The anatomy of responsive images Oh my.
h2non/toxy Hackable HTTP proxy to simulate server failure scenarios and unexpected network conditions.
Black Screen A modern terminal emulator based on Electron.
BDD is about starting conversations, because every time you bring it up you have to have a conversation to define the term.
Is it Pokemon or big data? Another fun guessing game.
git reset --hard HEAD

Lessons Learned From Reading Postmortems The role error handling, configuration, hardware, and human error play in outages:
Drilling down further, 25% of bugs are from simply ignoring an error, 8% are from catching the wrong exception, 2% are from incomplete TODOs, and another 23% are “easily detectable”, which are defined as cases where “the error handling logic of a non-fatal error was so wrong that any statement coverage testing or more careful code reviews by the developers would have caught the bugs”
5 Questions Every Unit Test Must Answer In a nutshell:
A failing test should read like a high-quality bug report.
What’s in a good test failure bug report?
- What were you testing?
- What should it do?
- What was the output (actual behavior)?
- What was the expected output (expected behavior)?
Considering a new engineering job? Wouldn't it be cool if you check the quality of their production code before you decide?
Five years, building a culture, and handing it off This is how you build a culture of success. And the ultimate test:
And building a thing that can be handed off means … you eventually hand it off.
How to Onboard Software Engineers I'm going to put this into action with our next hires:
The big ones are burning out senior mentors. Then that leads to, “We can’t take on any more junior engineers,” which is a huge travesty. When I hear companies saying that “We only hire senior engineers,” I’m like, “Who do you think is training all of these senior engineers? Where do you think they come from?” There are 2 ways to get great engineers at your company. You can steal them or you can make them.
When Discrimination Is Baked Into Algorithms Software algorithms are going to discriminate, that's their default state. What can we do to solve that?
@RichRogersHDS "This has been confusing our parents for years... #Programmers"
New cybersecurity mantra: “If you can’t protect it, don’t collect it” Exactly!
USB Rubber Ducky Deluxe Ducks like a USB thumbs drive, but also connects as a USB keyboard and types commands into the host computer, which is why you never plug foreign USB objects into your computer.
Adult Supervision (PDF) Blake Ross couldn't wait 8 month for the next season of Silicon Valley, so he wrote his own episode. And it's fantastically funny and true to form:
We're "managing you out" of the CEO role, not Pied Piper itself. No one knows more about the tech than you do.
So...you're looking for a CEO with a little less experience?
None of the Above
Avoid Humans Leave the house but keep to yourself? Avoid Humans combs data from Foursquare/Instagram to give you the nearest places with the least amount of humans.
AirConsole Brilliant. Play console games on your computer, using your iPhone as a gamepad. Works in the browser, no app to download/install.
Take better selfies Fantastic guide for cisgender men who are generally (myself included) not that good at the art of the selfie.
Full stop (n.) A punctuation mark that should be the only thing following the phrase “I am not a lawyer” in online discussion
Maybe This Global Slowdown Is Different We need to adjust our economic models:
Finally, consider the things that people do want to spend their money on. The defining consumer product of our age is the smartphone. … Most of its value is in the software that is loaded onto it and the people, information and entertainment you can connect to with it. That's a different sort of value creation than 20th-century resource-based value creation.
How Google defines ‘quality content’
But what they show is that marketers were correct in their assertions that the days of trying to ‘game the system’ are pretty much over, and now it’s about putting time and effort into creating content that is genuinely valuable.
Ashley Madison Code Shows More Women, and More Bots You expected Ashley Madison to be above board?
I used to do this:
"Can you do it in 2?"
"Yes but it'll be late by 1 day"
