The restriction goes to 18k because that's the top of VFR space. Anyone operating above 18k has to be on an IFR clearance and under positive ATC control. That makes it easy for the feds to make a call and say "Hey, center, get everyone out of this airspace" wheras in the VFR altitudes it's very difficult for them to legally clear the space since a VFR plane could be flying around not talking to anyone.

Fetchmail ftw

What's missing is GenZ isn't into it. The kids are the ones that go out all the time and they drive a lot of the revenue that big clubs need to stay alive. I'm not really sure what GenZ is into instead -- would've been cool if this article had tried asking them.

Yeah, came to ask this. Aren't global shutters becoming a thing? One would assume they'll be commonplace in the not-all-that-distant future, given their advantages.

Or they could have maybe lead with that sentence and THEN given the explanation.

Too many tech people have that "I want to slowly lead you to the point like Sherlock Holmes mystery" style of writing, and it is such a time-waste. Arthur Conan Doyle was paid by the word, you aren't. Please, everyone, back to middle school: State a Thesis in your first sentence and THEN expand on it, don't force me to spend pages trying to figure it out.

EV drivers more than make this up by not having nearly as many externalities (pollution) as gas drivers. Gas drivers seem to always conveniently forget those real societal costs when they're trying to talk about "fairness".

It's 100% about being able to stop adblockers

Sigh. I really liked reddit, too. :(

Do you want research or do you want an analogy? I can give you both. On the research front:

    "An Experimental Analysis of Erase-to-Program Interference in Multi-Level Cell NAND Flash Memories" by F. X. Zhang, et al., in IEEE Transactions on Electron Devices, vol. 63, no. 4, pp. 1621-1628, April 2016.

    "A Study of Erase to Program Disturbance in 3D NAND Flash Memory" by T. Wang, et al., in IEEE Transactions on Electron Devices, vol. 64, no. 7, pp. 3153-3159, July 2017.

    "Characterization and Modeling of the Erase-to-Program Disturbance in Multi-Level Cell NAND Flash Memories" by R. Micheloni, et al., in IEEE Transactions on Electron Devices, vol. 56, no. 11, pp. 2384-2392, Nov. 2009.

The problem with this is that erase-to-program delay is a major factor in bad write quality.....you really don't want to erase a block and wait a long time before programming it. Where "long" is subjective and there are a lot of details here but the general rule is that the longer you wait after an erase to write, the less accurate your write is (colloquially, your zero decays as it sits)......so in practice while you do erase-ahead, you don't erase too far ahead of your writing and you certainly don't erase at TRIM time in most cases.

The density is what's most relevant and interesting here. Pure is putting 28 of these drives in 3U - so 8.9P of nand in 3U drawing ~3kw of power. Pure gets ~2.5 data reduction on average (deep compression & dedup) and so the real world density is pretty impressive.

Yup, looks like I mis-skimmed the article. Thrown off by the (somewhat out of place, in retrospect) quote about it. My bad.

Sadly OP is behind the times here. The storage industry has pretty much co-opted GB to mean 1000^3 bytes, which is why you see folks in the know refering to GiB for the power-of-two-numbers. This is super-frustrating, but it's been like that for decades (literally: this was finally "officially" resolved in the late 90's by the IEC).

It's frustrating that SanDisk used to give you extra bytes and they stopped -- and everyone including me HATES it when products get worse with no external indication that they changed.......but let's be honest: it's kind of SanDisk's primary MO to buy the cheapest NAND they can find and sell it on the consumer market.

Seriously. Give me back an office with a door, or at the very least give me a comfortable space (ie not sweatshop layout or huge cube-farm) and I'm back to the office in an instant. I'm old enough to remember when I could focus _better_ in my tech office than I can at home...
