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's a little bit of logic, a little bit of munging, but

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 there is probably a good reason why NT won't

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 minutes of downtime. Implying that other changes require

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 k8s and nomad to schedule executors, an

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 virtuals entirely), avoid complex object graphs, a

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 wage theft in some sense but isn’t the same thing as requiring

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 a guy threw at him and then suffered serious side effects.

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.

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 without that.

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 real, if you know what I mean.

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 the benefits of your repo being a peer of the mast

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 and replaces it with a call to memset? Special-casing instru

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 not roses for them, either[0]. The thing tha

Windows likes local time on the RTC. Way back when DOS 1.0 was released (every story about Windows begins with this) there was one way to set the system clock: the user would type in the time. They would use the local time, of course. Consi

Um yes JIT intrinsics do that. Well, the JIT is recompiling as needed (or more often), but your bytecode isn't changing.

They're not that different, either. It's been a long time since high-performance cores were executing the instructions as fetched and not translating into µops. The stuff Intel does on their chips works on ARM too. People are doin

By your description, a jet is an intrinsic written by people who don't know about intrinsics. Plus the bonus of "if you don't trigger the intrinsic it literally costs you money" which is the kind of language-gotcha innov

That has bugged me since the first time I read about Nock. JITs use intrinsics to work around inefficiency of generated code when the maintenance burden of the intrinsic is worth the performance boost, and the grand plan is to make a VM so
