Fwiw, more recent versions of Druid have a no-rollup mode that does ingestion row-for-row. It ended up being useful for cases where you _do_ care about every row, maybe because you want to retrieve individual rows or maybe because you don't want to define your rollups at ingestion time. And in that mode, Druid behaves like the other DBs you mention.

(I am a Druid committer.)
yes - I may convert one to jekyll or hugo next few days if I have time. These look great and code is clean.
I'd really love to know too, but so far we haven't found any explanations. The loader is actually using all asynchronous writes, so there are no fsync() calls during the loading phase at all. The CPU usage is about the same as for the load on flash, so the delay can only be attributable to the actual I/O operations. Perhaps this data set just magically happens to cause a write access pattern that's pathologically bad for Optane SSDs. We re-tested multiple times though and always had the same result - runs fine on flash, slows down on optane.

Even LMDB on the raw block device, which immediately did a physical write upon every logical write, wasn't that slow. It's just bizarre.

I don't think that is an accurate summary of the situation at all. In particular your characterization asserts indirectly that that the employer is doing something wrong, that if only they were "willing" the problem would be rectified. But it is nonsensical to think that a business is going to willingly make choices that go against its own self interest, that hurts its business.

It makes no sense to hire an employee for $X/hour if that won't increase revenue by at least $X/hour.

It makes no sense to raise prices to cover an employee's wages/training for $Y/month, for example if revenue goes down by more than $Y/month (higher prices => less sales)
We are talking about someone defecating on a train station platform.
Write latency can be lower on flash-based SSDs than Optane because the former tend to have DRAM caches, but Optane SSDs have little to no caching. The difference isn't enough to produce that large of a discrepancy, so I suspect that the data being written to the Optane SSD was either not being batched into blocks of the same size as for the flash SSDs, or that fewer operations were being queued simultaneously for the Optane SSDs. I wonder if there were some mkfs or mount options that defaulted to a different value for the Optane SSD. I'm also curious whether the NVMe driver was used in polling mode.
When I said dependencies, I was not referring to dependency management. I was referring to the footprint of the toolchain. I'll reply to parent on what I meant in more detail, though.

Doesn't the root comment come to the opposite conclusion, though? From its last paragraph:

> Perhaps the real solution is to change the laws so that no one can legally take advantage of these loopholes, no matter how much money or resources they have.

i.e. if a law was created with the supposition that in practice it would only apply to a certain subset of cases to which it could in theory, then change the law so that it is universally applicable.

That being said, your "robots in the sky" scenario strikes me as a perfectly plausible example of a techno-dystopia we could create for ourselves far enough down that path.

Since the loader was performing asynchronous writes, actual batching would be whatever the OS is doing when it eventually flushes dirty pages to the underlying device. I can't imagine the OS using different queue depths during the RocksDB run than the LMDB run. mkfs/mount options were identical for both. We didn't touch the NVMe driver at all, so whatever its default behavior is, was used on all tests.

That seems inefficient and slow. Someone I knew growing up wanted to drive sooner. They asked their father to get them a new birth certificate.

Nothing at all, really, but kernel developers are going to be picky. For example, does LLVM target all of the architectures Linux supports today? Also, I think it's hard to sell Rust as a hard dependency of the Linux kernel when it isn't nearly as widespread as almost every other kernel dependency.

I also sorta remember some kernel developers (not necessarily Linux) making a fuss about rustc using a huge amount of address space and not working on 32-bit systems for that reason - although frankly, I can't remember where I read that and I'm starting to question how much I'm misremembering there.
1) Yes I think incentive structures are a part of it. For us as authors,I know I typically think about the website very differently than the book. Having an editor peer review also helps keep me focused. What you find with a lot of open source coders, they tend not to always be good writers (me included). My book is 530 pages and took 2.5 years to crank out in between new releases.
My company funded the book's development more as a loss leader. Authors don't make crap from the royalites. You're better selling it as part of a larger package such as training or support.

2. You have to know the right people. Go to the conferences and ask them. It took a long time. The profit shares aren't much. I more did it for the exposure at their conferences. We found it to be worth it as part of a larger package and networking with others in the field more than anything else. The notoriety has really helped as well. It's a lot of work, but definitely worth it if you can get it. Just be ready to put in a metric ton of work.

Hah, I don't know if someone that senile could actually pass for 49. "Age is a choice!" like if he wanted to be born in 1230, we'd all just have to go along and agree that it is true and makes sense with our concept of time. No, it doesn't work like that.

Maybe he should've taken the time to convince the people drafting his birth certificate to put a different year on it back when they were writing it... if he can't do that, then he shouldn't have the power to change his age.

Of course, he can certainly lie about his age on tinder. Don't know why he needs a lawsuit to do that.

Interesting comment...considering concurrency in Rust is significantly safer to do.

This is the whole point of the borrow checker which is to ensure data-race free code.

The story with concurrency is still being worked out with async server-side applications which is coming together swimmingly!

Threatening a person(the possible governor) is different than threatening the entire black population. If white supremacists wanted to just kill random black people, they don't need a voter roll for that. If they wanted to kill just black people who voted for Abrams, the voter roll doesn't tell them that. If they wanted to kill anyone who would vote for Abrams, then expressing your support for her on facebook seems far more dangerous than actually casting a secret ballot.

I can't tell if you're serious. Name and gender are labels we put on ourselves. Gender can be a bit of a gradient.

Most data/operational historians are separate programs on top of databases, so is that what you're actually talking about? Your papers seem to suggest that.

I mostly agree with this and I’d add: work does not have to be a “job”. Work can be your family, it can be art, and it can also be exploring the universe. I think Star Trek captures this idea very well.
Sure, fine, but most black people alive today did not live through the Jim Crow era. If the klan wants to terrorize black people, they don't need the voter rolls to do it. Go attack any random black family and the odds are good that you just attacked a family with at least one voter in it.

Seriously. Progress in microscopy hasn't slowed down at all. There was an Nobel prize given for optical super-resolution imaging recently. Cryoelectron tomography is insane: near Angstrom level resolution of 3D segments of cells. People are measuring the entire transcriptome of single cells using microscopy. Optical tweezers are allowing researchers to measure forces inside cells by literally grabbing intracellular structures with a laser and yanking them around.

Progress in sequencing is also exciting, but don't discount microscopy!

Amazon Kindle Paperwhite (2018) review: the new best-seller
When you put it that way, I don't think I understand your point. When you vote you actually don't pay anything.

And if you have a nonzero chance of affecting policy with your vote, your vote definitionally matters. We're in agreement on this. We can quarrel about the normative of whether or not there's a marginal cost that outweighs the benefits of voting, but it's functionally free and materially meaningful.
No It is not normal.

Atleast, based on the experiences of Rand Fishkin (of Moz.com fame ) as recorded in his autobiographical book [1] "Lost and Founder: A Painfully Honest Field Guide to the Startup World". In it, he elaborates on his experience with working with VCs at different stages and what is normal and what is not. It should be required reading for anyone working with or approaching VCs.

His Arguments: Since VCs already profit from your acquisition, they are part of the team. They are stakeholders just as you are. The main reason they are allowed on board, is so that they can provide advice on how to lead the company. So no fees for advice or such.

Also, another important aspect he points out. Sometimes, what is good for you and your company is at odds with what's good for a VC. Thats because VCs expect enormous growth from the successful companies to offset the loss of investment in the startups that don't pan out. A startup with a more modest year on year growth does not cut it from them. Yet that might be the best strategy for you and your startup.

It's been some time since I read it, so I am a bit rusty. He enunciates all this much better.

That is an incorrect analogy. Semaphores are the "goto" statement of the concurrent world.

Semaphores are not typed. They is no semantic connection to the thing they protect. Debugging concurrent systems with mutual exclusion enforced through these low-level primitives is a nightmare.

If you forgot to lock/unlock, you'll never know! The compiler cannot check it. Deadlocks are imminent.

We've had better abstractions since the 80s. Conditional critical regions, monitors, and (ideally) protected objects. Hell, even guards are better than semaphores and mutexes - at least they are associated with their critical region!

I struggle to think of situations where a semaphore is the best choice. Maybe in extremely high-performance cases, but even then the compiler can usually make a better decision.
What I enjoy about Spectre.css is that there is no javascript and the CSS is readable. It's easy to drop their CSS into a react component and extend it because it's so readable.
