I have a Myo as well, and it's pretty disappointing. The gestures are so rarely recognized correctly for me (maybe 20% of the time for the fist, pinky to thumb and open palm) that it's always easier to do the action another way. O

The Verge has a first look at the new high-end Kindle Voyager [0] and it sounds like the increased resolution (300dpi) really makes a difference. I'm also excited that the screen is now glass. The old plastic ones were very easy to scr

The OAuth way of doing things is to have two tokens: an auth token and a refresh token. The auth token is the one you send with your requests to authenticate them (and can be a JWT), but it has a very short expiry time (say an hour). The re

Tokens can be either signed (using JWS [0]) or encrypted (JWE [1]), which means that you're just trusting that your encryption/signing key hasn't been leaked. [0] https://tools.ietf.org/html/draft-ietf-jo

JWTs are a pretty great solution for various authentication and authorization related problems, like OAuth tokens, password reset tokens and the like. Using an information-bearing (and signed) token like a JWT tends to make your web apps le

Backpack isn't "kinda" illegal, gray-area, like AirBnB or Uber. It's straight-up, completely illegal. And this isn't municipality-level policies it's up against, it's customs and border, national law. I ca

This is solved in a more general way in Java 8 via monadic optionals. The basic idea is to wrap your nullable objects in an Optional<T>, which then both forces you to deal with the possibility of the value being absent and gives you g

I went last year, and had a great time. I didn't find the talks particularly useful (although they were often fun and I would call Chase Adam's Watsi talk legitimately inspiring), but I think the real value in an event like this i

Sounds very similar to Hitch[0] which launched a couple of months ago in SF. It sounds very useful for long, expensive trips (e.g., cross bay, down to south bay) where the fixed cost of picking up or dropping off another passenger is a smal

This is the norm in other industrialized nations. It's called local loop unbundling [0], and comes in several different forms. In some countries the local telco monopoly is prohibited from selling to end customers and must lease their

It's not used for tolerating disk errors (typically in a production context you have RAID for that, and failures tend to be for the entire disk). It's used to reduce storage requirements via striping. See the QFS paper ( http:&#x2

That's not a fair comparison, as the flatMaps are eating nulls (really Optional.empty()s) while the naked calls will throw NPEs. The equivalent code for the first case is: String result = "UNKNOWN"; T a = X.getA(); if

That would definitely be an improvement. When I originally wrote this in 2011, I had just a few hours, so I went with the quickest solution. For little personal side projects like this I find that Redis makes a great persistent hash map for
