That's another gotcha-- interning of strings and boxed primitives.

Are there linters for this sort of thing? I don't write Java much any more.

Autoboxing's evil twin, auto-unboxing should knock the score down a few points.

  Integer a = null;
  int b = 42;
  if (a == b) {} // throws NullPointerException

It's useful and very common to use. For example, you could concatenate together command-line argument flags that may or may not be present.

A separate VLAN, if your router is capable

The PDF metadata says it's PyPDF2

It does! Code is here https://github.com/java-native-access/jna/blob/40f0a1249b5ad...

That's how java.io.File#deleteOnExit works under the hood. The DLL is still loaded at that point and can't be deleted.

According to JNA it's not safe to unload the DLL:

https://github.com/java-native-access/jna/blob/40f0a1249b5ad...

  Do NOT force the class loader to unload the native library, since
  that introduces issues with cleaning up any extant JNA bits
  (e.g. Memory) which may still need use of the library before shutdown.

  Remove any automatically unpacked native library.  Forcing the class
  loader to unload it first is only required on Windows, since the
  temporary native library is still "in use" and can't be deleted until
  the native library is removed from its class loader.  Any deferred
  execution we might install at this point would prevent the Native
  class and its class loader from being GC'd, so we instead force 
  the native library unload just a little bit prematurely.

You would also need to learn about Maven profiles and activation. And for other build tools, you'll be delighted to know they have partial support.

This wouldn't work on Windows, because you can't delete a DLL while it's in use

Native libraries are typically packaged inside a jar so that everything works over the existing build and dependency management systems.

For example, each these jars named "native-$os-$arch.jar" contain a .dll/.so/.dylib: https://repo1.maven.org/maven2/com/aayushatharva/brotli4j/

JNA will extract the appropriate native library (using os.name and os.arch system properties), save the library to a temp file, then load it.

I can't think of another statically typed language that screws this up so badly. It just keeps getting worse with stuff like Optional and @NotNull.

Java might be the only language where a simple assignment `x = y` can throw a NullPointerException (due to auto-unboxing)

Or more succinctly

  val num = words.count(_.nonEmpty)

This cheatsheet would have you publish dist/*.{js,d.ts}. Presumably you would use "files":["dist"] in package.json to exclude sources from being published.

The OP recommends to additionally package src/*.ts along with sourceMaps and declarationMaps.

What's actually the best practice here?

California Code Regulations, title 10, Section 2632.5 - Rating Factors

It carves out an exception for "using a technological device to collect information about the location of the insured vehicle as part of an emergency road service, theft service, map service or travel service."

It's the same in parts of the US. In California, insurers are only allowed to collect the mileage.

Maybe a foldable e-bike would be a good compromise?

You can use G1 on Java 8 with -XX:+UseG1GC

You can use ?. or assign to a nullable type. Or you can get a NPE at runtime. Which is to say, it's not null-safe.

Kotlin interops nicely with Java but it's not null-safe (all references from Java are assumed non-null).

This seems to work:

  document.querySelectorAll('video').forEach(v => v.playbackRate = 1.5)

And the purpose of "T extends string" is to carry the value of a string literal. For example, there's the string value "foo", but there's also a type "foo" which extends string and has only the one possible value.

There's a mechanism: if people want their bulbs to match, they might pick the same brand/model as a replacement

now you have N+2 problems?

Are you conflating CORS with some specific product?

Pinned versions don't mean anything when sub-dependencies can have transient versioning resolution occur.

That's the purpose of lockfiles-- to pin the entire dependency tree.

When I search for an identifier it comes up with usages, tests, docs, etc. I have to dig several pages to find the declaration/definition.

To clarify, the arrested individual sells a swatting "service" [1]. One of the CoD players hired him to swat the other over a twitter argument. The other CoD player taunted the swatter and gave him a random address [2]. The police showed up at the address and killed an unrelated person.

No parties involved are without blame.

Look closely. Or, equivalently

  > n=12345678910111210
  > n+1 === n+2
  true

Kotlin has its own standard library
