Don't use VPN services.

No, seriously, don't. You're probably reading this because you've asked what VPN service to use, and this is the answer.

Note: The content in this post does not apply to using VPN for their intended purpose; that is, as a virtual private (internal) network. It only applies to using it as a glorified proxy, which is what every third-party "VPN provider" does.

• There's also this article about VPN services, which is honestly better written (and has more cat pictures!) than my article.

better caches with rethinkdb

TL;DR - smelly software engineer discusses using rethinkdb changefeeds for building caches, breaks hearts, shaves the cheerleader, shaves the world.

Let's talk about caches.

Imagine that you build UIs for an ecommerce company, possibly in a fancy office with free coffee and whatnot. You've just been asked to build a way for the marketing / sales folks to change landing pages whenever they're running campaigns. After a number of angry discussions involving the ux team about what they can and cannot change, you settle on a 'document' format for these pages. It could be json describing a tree of widgets of banners and carousels, or html, or yaml, or whatever. Maybe you also invent a dsl that marks out parts of the document as dynamic, based on request parameters or something. I dunno, I'm not your boss. You build a little ui over the weekend (with react? maybe!) that lets these folks login, drag and drop their banners, maybe upload an image or two, and save to database.

This disables app transport security and allows non-HTTPS requests.
Note: it is not recommended to use non-HTTPS requests for sensitive data. A better
approach is to fix the non-secure resources. However, this patch will work in a pinch.

To apply the fix in your Ionic/Cordova app, edit the file located here:

key is pretty much crucial for state perservation in React. As of React 0.13 it can't do the following things:

• Clone state

<Comp key={1} /><Comp key={1} />

• Preserve component state across different parents:
