Metrics Versus Experience Bad decisions can be made in the name of "lifting metrics", that doesn't mean metrics are bad. Julie presents her framework for using metrics effectively:
- To assess for product-market fit, look at retention.
- To optimize for growth, understand your funnel.
- Figure out which metrics are truly important, and focus on those.
- To figure out the best metric to track, use the magic-wand technique.
- Don’t just accept a metrics goal without understanding it.
- View data skeptically by suggesting countermetrics.
- Use qualitative research to get at the why.

Figma VS Sketch Like Sketch, but works in the browser and with real-time collaboration.
antirez/neural-redis Oh yes!
Neural Redis is a Redis loadable module that implements feed forward neural networks as a native data type for Redis. The project goal is to provide Redis users with an extremely simple to use machine learning experience.
Support for #RGBA colour values may validate previously invalid values TL;DR
#0000 is not black but transparent.
Lesser known Git commands
git please, the gentler alternative to force push.
Machine learning without the PhD - azure ml Oh so true:
80% of any data scientist's time is spent cleaning data leaving just 20% of the time to complain about cleaning data

Hunting for great names in programming The details matter:
Now this might seem like a lot of effort to expend searching for a slightly better name, but it goes straight to the heart of programming with a smile. I ventured out to find a great name, not just a passable one.
What does it mean when code is “easy to reason about”? A helpful exercise:
By going through the the above steps, we’ve slowly built up a function that is easy to reason about because it has these key qualities:
- Does not have unintended side effects
- Does not rely on or affect external state
- Given the same argument, it will always return the same corresponding output (also known as “referential transparency”).

Keeper of Lore This whole thread:
But never, -EVER- distribute a device with default credentials.
Even if you 'make' them change them.
[ Because if default creds exist, people will change the creds back to the default, and it ends up being exactly the same as no change ]
On Phone Numbers and Identity This is important:
The assumption that control of a phone number is sufficient proof of identity is false. Just as we should no longer trust SMS for two-factor authentication, we shouldn’t trust it for account recovery. Disable this anywhere you can.

WILK: And it was the only question that we ever wrote where we ever got a response from them saying, is this actually what you want us to be polling? And we said, yes.
