> including the way snow doesn't just immediately turn off but stops falling slowly. I love it.
Funny, i disliked this exact detail. I thought turning it off hadn't worked for a few seconds and i retoggled it on and off a bunch of times before i got it
> “All you could smell was sulfur hydrogen, and you cannot breathe,” Dr. Vrenozi said, recalling that most of the researchers were wearing masks. But as they descended deeper into the cave, she said that “you get used to the smell of spoiled eggs.”
Also, you use "" but you are not quoting, the text inside your quotes does not exist in the article. The actual quote would be
> The cave is hard to reach and is filled with foul-smelling hydrogen sulfide gas, in concentrations too great for most animals to live there.
Getting used to the smell could be an extremely bad sign, in fact.
With hydrogen sulfide, olfactory fatigue can occur at 100 ppm, and paralysis of the olfactory nerve has been reported at 150 ppm[1]. Those levels are considered "immediately dangerous to life and health (level that interferes with the ability to escape)"[3]
So you might think the gas is gone or that you're "used to it", but you're being poisoned and are at risk of losing consciousness and dying.
However, according to [2], "the atmosphere in [Sulfur Cave] can reach concentrations of up to 14 ppm of H2S". According to [4] that's below the "acceptable ceiling concentration" of 20 ppm, with up to 50 ppm for a 10-minute period being acceptable for an 8-hour shift. So these levels are in the "not great, not terrible" category. Wearing a mask is highly advisable.
Yes, that was my thought as well. As a youthful experimenter, I once did not clean up properly after myself and stopped smelling the H2S which was permeating the room (Back then, the recipe for H2S was in chapter 1 of the Chemistry sets. Good times!)
Before replying I searched the entire page and did not find your quote anywhere, including the captions. To make sure I did not miss anything I even only searched for a single word from your quote, "hydrogen", then "animals", and there are only three (two) places in the text, none in the captions.
I'm not sure if NYT articles are known to change their images and captions for different viewers? I checked the archived link too.
>Acute inhalation exposure to high concentrations may result in collapse, respiratory paralysis, cyanosis, convulsions, coma, cardiac arrhythmias, and death within minutes.
>Exposure to low concentrations may irritate the eyes and respiratory tract, resulting in sore throat, cough, and dyspnoea.
This would require new software and new ASICs on all hosts and routers and wouldn't be compatible with the old system. If you're going to cause all those things, might as well add 96 new bits instead of just 2 new bits, so you won't have the same problem again soon.
I use Jenkins every single day, and have been using it my entire career through three different companies self hosting it.
Please tell me how we somehow have been hobbled despite having simple and clear pipelines setup that autobuild any branch we want and allow one click deploys to our preprod environment and automatically manage versioning and scalably handle load from "Literally zero" to "Everyone in the company wants to rebuild everything now" and goes down less than github.
What are we supposedly missing?
More importantly, what are we missing that tangibly improves results for our consumers?
Working with Jenkins CasC, JobDSL and declarative pipelines, I'm not sure where the million times comes from. Sure, there are some annoying parts, and GHA has the social network for reusable actions, but apart from that it's not that different.
Oldschool maven type jobs where you type shell script into a `<textarea>`? Yeah, let's not talk about those, but we don't have a single one left anymore.
I've been wondering if the stock market would be more efficient if trades executed only every <small time interval> instead of continuously, i.e. every 1 second an opening trade style cross book clearance happens. Orders would have to be on the book for a full interval to execute to prevent last millisecond rushes at the end of an interval
I'm probably missing some second order effects but it feels like this would mitigate the need for race to the bottom latencies and would also provide protection against fat fingered executions in that every trading algorithm would have a full second to arbitrage it
You could do this but the cost would be wider bid/ask spreads for all market participants. If you make it harder for market makers to hedge their position, they will collect a larger spread to account for that. A whole lot of liquidity can disappear in a second when news hits.
I’d rather have penny-wide spreads on SPY than restrict trading speed for HFTs. Providing liquidity is beneficial to everyone, even if insane amounts of money are spent by HFTs to gain an edge.
It's really binary events that they should throttle execution and do batch orders.
The bad part of HFT is paying the smartest young minds this country has to offer to figure out how the parse GDP data as fast as computationally possible so they can send in an order before other players can. That's a dumb game that doesn't provide much benefit (besides speed in sparse critical moments adding a few % to the funds ROI).
They can arbitrage all day, but don't let them buy every Taylor Swift concert ticket the moment it goes on sale because they have a co-located office with a direct fiber line, ASIC filled servers, and API access.
Would be interested to see real numbers around societal value from marginal added liquidity versus aggregate spend into the zero sum arms race.
I have also seen enough to be quite sure that many hft strategies are quite normie investor predatory.
Again, I’m not zealot. I trade stuff. I love liquidity. I’m happy to pay someone some fraction of a penny to change my mind. Service provided. But the returns from vanilla liquidity provision commoditized long ago to uninteresting margins. That leaves a lot more of the hft alpha pool in the predatory strategies and capital flows where the incentives are.
that depends, if you explain the rules of the game you're playing and give the dice a goal to win the game, do they adjust the numbers they reveal according to the rules of the game?
It's a vacuum + mop combo which imo is way better for hard floors
