Django SQL Dashboard

It can also be used to create saved dashboards that can be published or shared internally.

Weeknotes: Working on my screenplay

I’m taking an Introduction to Screenwriting course with Adam Tobin at Stanford, and my partial screenplay is due this week. I’m pulling together some scenes that tell the story of the Russian 1917 February Revolution and the fall of the Tsar through the lens of the craftsmen working on the Tsar’s last Fabergé egg. So I’ve not been spending much time on anything else.

I’m in Polanco (Mexico City) and I hate it. Where to go?

You said you want to avoid expensive taxis.. are you morally opposed to Uber? If not you should know that it works in Mexico City (with your regular Uber account registered in another country), it’s fast and not very espensive. It may give you a lot more flexibility for exploring the city.

Why is site search so bad on most websites?

It’s not so much that site search is bad, it’s that your expectations have been raised enormously high by the incredible quality of search provided by search engines like Google.

Is there an API that returns metadata for a given URL?

I suggest taking a look at http://embed.ly/—it can take a huge range of URLs and turn them in to JSON metadata. Here’s what it can do with a Wikipedia page: http://embed.ly/docs/explore/obj...—and here’s Google Maps URL (not as useful, but still some interesting metadata extracted) http://embed.ly/docs/explore/obj...

How did art.sy get a “.sy” url?

Which sites have the best URL design?

GitHub’s URL design is fantastic—it’s a virtually flawless mapping of Git semantics to URL space. Their basic URL structure is excellent, but they also have a bunch of neat URL hacks going on. Here are a few of my favourites:

When referring to our web site in publications (or Twitter or Facebook), when is it important to provide the full URL—http://www.mywebsite.com and when should you provide just the mywebsite.com?

You have no control over how other publications refer to your site—if you’re lucky, they might spell it correctly and check the link works before publishing (but I wouldn’t bet on it). What you DO have control over is making sure you compensate for any mistakes they make.
