Yes. I'd highly recommend making `git pull --rebase` the default behavior of your `git pull` operation. I'd thought that the Git folks were going to make this the default behavior at some point. It really ought to be. `git pull --

I believe that garbage collection is a net win because it allows software to be composed in simple ways when it would otherwise be difficult to compose. I can pass data from one part of the program to another without coordinating both parts

Postmates used to require you to specify the rating & tip on the courier's phone on pickup. Some time ago they changed it such that now you can specify the tip on your own device any time after receiving the order. (I had sent this

The Pomodoro Technique, which is mentioned on the page, has been helpful to me when I need to concentrate on solo work privately. I'd recommend it. It's an effective technique, and the only one I've discovered that's bee

We're talking about deliveries to Gmail, and Gmail can decide what kind of client certificates count as authenticated when sending emails to Gmail. For example, they could establish the convention that the highest tier of lock icon req

I think this is a good move that establishes a useful foundation, building on the work that Google has done thus far in their Safer Email effort. The quality of the security depends on the implementation details, but being Google, I would e

No, annotations do not accomplish the same thing in practice. Annotations function properly only when the code was written with annotations, and where the code and all callers are checked against the annotations. Unfortunately, annotations

If you are in the midst of an upgrade like this, then you might want to program defensively. In this case I would do that by applying annotations like FindBugs' @CheckForNull or @Nonnull or @Nullable. Across a trust boundary like an in

> Optional<T> myOptional = null That hasn't been a problem for me in practice. It's pretty clear that a reference to Optional should never be null. It can be statically or dynamically checked with @Nonnull or a preconditi

by jcrites 11y ago
The lack of pattern matching doesn't make it useless. The existence of Optional reminds the programmer to check whether the value is present, and the type system does enforce this; you can't accidentally treat an Optional as a ref

This raises an interesting meta-question for founders and investors. How can you differentiate ideas that are "just not that good" from ideas that could be amazing, but need adequate investment and execution? I never would have gu

I don't have any special knowledge of GFS, but one purpose of distributed file systems of that sort is generally to avoid the need for additional backup by replicating the data many times as part of its routine operation. The data stor

It's fun to try to explain concepts, and a nice way to refresh memory, so let me take a shot. Imagine a programming language where no function returns a value. Instead of returning a value, the function calls the callback and passes w

It's something you could arrange if you wanted to, but it could be pretty complicated! Swapping individual classes within a VM and having multiple classloaders could be very nuanced to debug. I suspect it would also complicate usage of

In software engineering, elegance is prized and is often related to efficiency in several layers. At the human layer, one expression of this idea is the principle of least astonishment: "People are part of the system. The design should

True, but I think part of this is about shaping behavior, and about self-discipline. And perhaps also the cognitive bias that comes from knowing one's own program well. A program I wrote always seems more obvious to me than it does to

Type inference can make the code easier to write. But, is the code easier to read, and overall less effort for the business? Code tends to be read significantly more than it's written. This is a simplification but seems to be true enou

Tips are largely a red herring in discussions of minimum wage, since tipped workers always earn minimum wage regardless of whether they get any tips or not. This is true under US federal law, at least, though I haven't researched how i
