Sounds like they can do predicate pushdown to the storage nodes now. And...mainly beneficial for medium-to-highly selective scans of mostly uncached tables?

I am a dataologist, even if my title says software something something. Commercial software development is about getting data from point A to point B more than anything else. There…

IOCP doesn't do it[1]. Well, if it does then it's not documented. You can post custom completion packets so at first glance it looks easy to make open/close be async...I think ther…

Reminds me of an IBM technical bulletin I found, somehow, about 10 years ago. It advised that if you were moving from this z9 hardware configuration to that one, you would have 30 …

If you're using Spark's built-in scheduler then the cluster manager is a SPOF. Hadoop docs say you can get active/standy ResourceManager, not that I've tried it. Spark can also use…

In addition, a lot of the techniques used to write high-performance Java boil down to "write it like C". Avoid interfaces, avoid polymorphic virtual calls (as you can't avoid virtu…

You're really stretching to find negative consequences there.

The short excerpt you can read for free says this is more about stuff like the two minutes between clocking out at closing time and locking the door on your way out. It might be wa…

Why, on the off chance one flies into someone’s open mouth and the surprise triggers a swallowing reflex? I wouldn’t have a lot of sympathy for an adult who ate the homemade pills …

Hanlon's razor?

That's why I took 102. They give you the straight dope there.

I always thought that force would work pretty well to build a dystopian hellscape.

Spicy. The fundamental problem is that a lot of people have jobs that pay a lot of money, I take it. You seem very upset about this.

On the other hand, I live far away and the YouTubes would be entertaining. Please do this, Google.

I guess they got the name back when smelling bad and smoking pot was progressive.

Gaslighted. Moonlighting is a different thing.

Oh my God, people use Slack without changing the "Notify me about" setting to "Direct messages, mentions, and keywords"? I work on a 100% remote team and would rapidly go insane wi…

Yeah, that sounds about right.

Deep learning! It does everything really well, especially reducing complex problems to a single number. It's well known that anything which doesn't fit in the reals isn't really re…

I'll go with twelve.

Yeah, if you’re pushing to prod automatically without a really good test suite then I would say the problem isn’t with the person who wrote a bug.

There's nothing about git that requires you to use it like the kernel does. Centralized version control is just a special case of decentralized, if you're using git. You still get …

> Like you said, their intent is just to add a new option, and it ought to have no extensional changes in behavior, but it still ends up behaving subtly different. The next morning…

Thank you (seriously) for the detailed explantion. JITs already do this, to my mind. What else are you going to call it when HotSpot sees bytecode for a loop initializing an array …

I was using "intrinsic" inappropriately, I think, to mean both substitution of method calls and substitution of bytecode patterns. Yeah, the JVM already does the second thing. It's…
