Even in lowly Java, they later added to Optional the orElseThrow() method since the name of the get() method did not connote the impact of unwrapping an empty Optional.

When I worked at Khan Academy, Charlie was an intern, and for a few months we worked together on building the KA app for Android. I can vouch that he was a damn good developer then, and I'm sure he's a much better one now.

Yeah, but it's the rank and file employees who will now think "I'm not there to defend myself against being fired if I take maternity/paternity leave" who will suffer most. The ones who won't be getting a severance larger than you can ever imagine.

Every other theory listed here is far more likely, but I would try changing your loop from using System.currentTimeMillis() to using System.nanoTime(). It's a higher-resolution time source that has no relation to wall clock time but is more appropriate for timings. Classes like Stopwatch from Google's Guava use it.

Agreed. Joda had the right abstractions (instants, durations, etc) but the class hierarchy for them was unnecessarily complex. A lot of this complexity comes from opting for the abstractions to be either mutable or immutable.
For example, `ReadableInstant` [1] in Joda implements 3 interfaces and has 7 subclasses. And really, what is the difference between `AbstractDateTime` and `BaseDateTime`? Whereas `Instant` from java.time [2] is an immutable value type and I haven't found it lacking in any respect.
On the whole java.time has struck me as extremely well designed (after coming from Python and previous date and time libraries in Java) and I think it would behoove other languages to liberally copy its design.

I have a horrible memory when it comes to the detail of books, movies, etc. (But thankfully I can remember what I've coded, or else I'd probably be out of a job.)
I mostly read non-fiction. To improve my recall over the past 7 years, I type up notes as I read. It's made the process of reading much slower, but it has helped when I've needed to recall some example or detail or framework of a book.
I did this (selfishly) for myself, but decided to upload my notes at https://github.com/mgp/book-notes. (Shameless plug I suppose?) The README explains exactly how I take the notes – but essentially there's no shortcut. I have my text editor open and simply type notes as I read.

Oops! My mistake – you are absolutely correct. Lombok was just so pervasively used in our services, I assumed it came included as part of the Dropwizard toolbox.

I used it extensively while writing Java code at Airbnb. (It came included with Dropwizard, which we used for writing services.)
Some people are uncomfortable with the extensive bytecode manipulation that it does. While Lombok provides annotations, it is not your normal annotation processor. From http://notatube.blogspot.com/2010/11/project-lombok-trick-ex...:
> Project Lombok hooks itself into the compilation process as an annotation processor. But Lombok is not your normal annotation processor... The trick is that Lombok modifies the AST. It turns out that changes made to the AST in the Annotation Processing phase will be visible to the Analyse and Generate phase. Thus, changing the AST will change the generated class file.
That said, we never encountered any Lombok-related problems when running services in the cloud or locally. And the Lombok plugin for IntelliJ is good enough in that the auto-complete will "see" the Lombok-modified version of the file. For example, using the @Value annotation creates an immutable value type, which among other things a) makes every field private and final, and b) generates a getter method for each now-private field. With the Lombok plugin, IntelliJ auto-complete will a) not auto-complete the composed fields which are now private, and b) auto-complete the generated getter methods.
I highly recommend looking past the voodoo bytecode manipulation and using Lombok. The @Value annotation alone is worth the price of admission and made me a more productive programmer.

I appreciate how the characters in the example are named Bart and Lisa.

Retrofit has support for RxJava, both of which are mentioned on the list. If Retrofit deserializes your JSON response payload as type T, then upon making a request it will return an Observable<T> that will either emit the result (if the request succeeds) or emit an Exception (if it fails).
Most Android applications that rely on both Retrofit and RxJava use them together in this manner.
As for too many requests pending, I'm not sure if OkHttp (which Retrofit uses for making requests and is again on that list) is configurable in that regard. If you want to handle it at the application level, you could maybe model the request queue to the network layer as an Observable<Request> and use RxJava's backpressure operators.
For more information on functional reactive programming (which I would call promises or CompletableFuture done better), see http://reactivex.io/

But explicitly spelling out to your wealthy competitor all the ways in which you kick its ass likely improves your chances of being acquired.

I'm not going to lie, I didn't like this post as much as I wanted to.
The author says that Google is making the same mistakes that LiveNinja made over a year ago. And that LiveNinja has learned a lot and iterated since then. At this point, I'm ready to believe that LiveNinja is the more mature product. That if I have a need, I should probably go to LiveNinja. I'm ready to be sold... But then the author does nothing. He don't actually tell me WHY LiveNinja is better. Instead, he mentions Google Answers, Buzz, and Wave.
Why not drop the ad hominem, and sell to your potential customers instead?

From http://docs.oracle.com/javase/7/docs/api/java/nio/charset/Ch...: "The native character encoding of the Java programming language is UTF-16."
That said, at least they adopted a Unicode encoding, and helped it establish mindshare.
