Adding ACID to Cassandra sounds very interesting, will be curious to read more about that.

Probably the best single resource is https://github.com/pmcfadin/awesome-accord

Cassandra needs ACID like a fish needs a bicycle ,-)

"When is "ACID" ACID? Rarely." - https://www.bailis.org/blog/when-is-acid-acid-rarely/


It would certainly be a boon if Cassandra did better ACID than everyone's favourite SQL DBs (which are unknowingly running on read_committed).

It's a good sign that they've got bank account balance updates in the example code in the Accord github (sibling comment), as that's what I reach for if I suspect my DB is only pretending to be ACID.


The Accord developers mostly work at Apple so it would seem Apple at least wants/needs ACID transactions for Cassandra.

On a Mac, at least, the "correct combination of buttons" is trivial and easy to remember, even for someone like me who rarely uses em-dash. (But, I want to start using it more because I'm sick to death of people treating it as a scarlet letter.)

Thanks for sticking up for my humanity ;)


> allow Bluetooth

I'd have a hard time getting over my aversion to this. I automatically reject any app's attempt to find local devices, etc.


I can't imagine how it would be possible to detect a phone in close proximity without allowing this though

Accelerometer, by putting the two phones together and shaking (some app used to do this, but I can't find it with a quick search). Edit: I might have been thinking of Bump, mentioned downthread, though it's a different physical mechanism: https://en.wikipedia.org/wiki/Bump_(application)

Camera, and point it at their changing screen (or both at the same scene at the same moment). Not too intrusive.

GPS, but that would require location permission. Intrusive.

Audio, but that would require allowing microphone. Intrusive.


slightly OT but the technology behind Bump was genuinely mindblowing at the time. Phones didn't have NFC or anything like that, and they didn't use much accuracy in the way of location data, so they basically just had a general "city block" location, timestamp, and accelerometer readings and would invert the accelerometer reading and look for identical accel + timestamp.

We tested it one time with like 10 phones and everyone bumping each other / the wall as a control, in the same room and it nailed every actual pairing and ignored the others. The wiki has more, but lacks the subjective experience of how magic it was.


That's what Bump did, like 13 years ago, by sending accelerometer and GPS data up to the cloud and correlating it there.

It works in isolation and fails miserably when trying to do a big demo of it in a conference talk when attempted by dozens of people in the same room.


NFC?

Is there a reason to believe he’s stopped? The articles are clearly very labor/time-intensive, so the current lag isn’t all that unusual.

Well, Bartosz used to publish 1–5 articles per year, but hasn't published any this or last year. I assume he's just got other things to do in his life, which is absolutely fair and I'm grateful for every one of the articles we got gifted and all—but at the very least he is taking a pause right now.

From another comment here: "you need to be able to keep the water below 24 Deg C, this means spending some money on chillers even in sub-tropical countries"

I think people anticipate needing heaters for certain types of fish, but I'd never have expected to buy a cooling unit for aquatic life.


Yeah, adding in a chiller makes things way more complicated than just adding a resistive heater. A decent looking chiller for an aquarium is ~$1,000, plus you need temp sensors and control wiring to maintain the setpoint properly, and then you need to pray the electricity doesn’t go out. A 1/3rd HP chiller draws around 1kW including the circ pump

An aquarium backup battery for a simple pump is like $50 for something that'll last a few hours of outage, but for a chiller with that kind of draw, it's a bit more expensive.

Yeah, you’d need a 1500 VA UPS to back it up, plus a decent amount of batteries (I don’t know the math on those, someone else figures that part out for me haha)

Aquarium circ pumps can probably be powered directly by 12VDC? That would make sense if it’s only $50 for battery backup.


I hope this assertion ages well.


“Everyone is special” is a snarky, derogatory comment we don’t need here.

It’s not snarky. It’s literally the argument people are making: I am special, my use case is exceptional, therefore I need to use the special tool, even if you don’t need to.

Technically Apple was never bankrupt. It certainly came within a few months, but never reached that point.

Let me get this straight: he accused grieving families of lying about their children's deaths, and put a target on their backs, to sell stuff...and he didn't believe his own bullshit?

Yeah, especially because he contradicted himself several times, it doesn't seem like he believed it. He's really committed to trolling.

Labeling someone a "troll" for that level of evil feels enabling to me.

Saying that he actually believes his grift can make him seem kinda innocent, but I'm not going to assume that's the intent if someone says it.

Saying two different things at two different times is not prima face evidence of lying. For instance: changing your mind is not lying.

Again, I find it ironic that you're using the same conspiratorial line of thinking that Jones himself does: e.g. "The CDC has changed their mask guidance so they must be lying about it"


It was convenient timing for him to call the shootings "100% real" the moment he ended up in court for it.

People often do realize they were wrong about their prior convictions when they're sitting in a courtroom, a decade later, faced with a life changing situation, and forced to hear overwhelming evidence of how they were wrong.

If this guy was some kind of savant, he wouldn't have been in that situation at all. There is no evidence that he is some evil genius. He has no higher education and is a diagnosed narcissist.
