Same here. Even though the "new" Dune has a lot of good VFX, I found it boring to watch, and that was only Part I. Before watching "new", I watched Lynch's to have something to compare to. I vastly prefer Lynch&#x27

Wow. Thanks for this. I'm usually indifferent to art, but these paintings are something else.

You don't just shut it down, but discontinue further sales instead so that existing contracts die gracefully.

So what to do about stuff such as lazy creation of objects? - Option 1: nullable reference and if the program crashes, you have a bug. (That should be caught during testing.) - Option 2: Maybe<T>, making the rest of the code unreadabl

Each time I read one of posts about JVM, I'm impressed by how they manage to deconstruct a "high-level" concept such as value type or reference type to more basic ingredients. Pinnacle of bottom-up design.

Since DAA generates #UB in 64-bit mode, I assume all such "adjust" instructions do (haven't bothered to check). In that case, is the auxiliary flag (AF) in the flags register used for anything at all in 64-bit mode?

In SQLServer you can define external tables that access data on another server, or even parses a file.

You can delete the name/directory entry, but the file remains allocated and in use as long as any program holds it open. So how useful the POSIX behavior is, is debatable.

No. That's why it's called _shared_ memory segment. Between processes. It's like an in-memory file.

Depends on what you're defending against. Sequential ids are easy to guess, and that's why we have ASLR for memory management.
