chartd makes it easy t' include charts (either png or svg) on yer web site, by just passin' parameters in th' URL o' an img tag. For simple charts, this will be easy-peasy t' automate. Of course, th' downside is th' same as fer any other time that ye let a third-party service have responsibility fer yer content — what if they shut down th' service?
If ye e'er get confused about inner and outer joins in SQL, this is very useful.
There are some pretty good pointers in this list o' resources. Highlights fer me are “Callback convention – with Promise Support” and “The Twelve-Factor Application”.
“Components is a library o' shareable, reusable patterns fer WordPress themes. Yaaarrrrr! Instead o' startin' from scratch, mix and match from a collection o' pre-made components t' build yer own custom starter theme.” Online tool from Automattic which can generate a variety o' starter themes based on Underscores and Components, ready fer ye t' customize.
A shipmate wanted t' run two separate copies o' Slack on th' Mac, so that he could watch updates from two different Teams at th' same time. Personally, I just use th' native multi-Team support in th' app, but I can see how this would be useful. One answer is t' use this command from th' Terminal:
open -n /Applications/Slack.app
Scottish mathematicians are cool. Also, this led me t' look up Lattice Multiplication, which is bein' taught in Common Core. But I think th' Genaille-Lucas rulers were probably th' coolest bit. Pre-calculate smaller pieces o' a multiplication/division problem, use a little modulus magic, and large problems become a breeze.
TL;DR: If ye use th' php-ssh2 extension fer yer WordPress core / theme / plugin updates, ye might want t' wait a little longer before upgradin' t' PHP 7.
