An interesting read from a doctor of philosophy with a consulting firm who went through a huge pile of management theory books to see what he missed by not having a formal “management education.”

Comparing Signal-protocol-using messengers
There’re still privacy differences when you compare messenger apps all using the Signal protocol:
In this article, I’m going to compare WhatsApp, Signal, and Allo from a privacy perspective.
While all three apps use the same secure-messaging protocol, they differ on exactly what information is encrypted, what metadata is collected, and what, precisely, is stored in the cloud — and therefore available, in theory at least, to government snoops and wily hackers.
In the end, I’m going to advocate you use Signal whenever you can — which actually may not end up being as often as you would like.

What Mafia Teaches Us About Trust & Security
David Eaves has some interesting thoughts on what Mafia can tell us about trust and security. He also has a few ideas on how the physical game setup gives advantage to different parties.
Leave Math to The Machines
Given the pace of technology, I propose we leave math to the machines and go play outside.
Drifting News
What if “trending news” would be made to drift in into a certain direction? Well, it seems that Facebook used their ability to manipulate curate trending topics to block out certain topics and set some of their own. ? Some should have warned us.

AR create_with
find_or_create_by
method but I didn’t know it had a very useful companion
create_with
.
@something ||= SomeModel.create_with(some: "stuff").find_or_create_by(foo: "bar")
This will either find a record
SomeModel.where(foo: "bar")
or create it with
SomeModel.create(foo: "bar", some: "stuff")
. Very useful.
AR Find Trickery
found = ModelA.find_by(id: id) || ModelB.find(id)
I stumbled over this during a code review. It was supposed to look for a record in two distinct tables.
find_by
will return
nil
if nothing was found while
find
will
raise
. Hence either you get something (from any model) or you
raise
.
