it turns out... it's blu-ray.
So Sony has this format called Optical Disc Archive, right? It's a high-density storage cartridge, but it turns out it works by cheating.
it turns out... it's blu-ray.
They've been launching new updates every couple years, with the latest version being the ODC5500R (launched in 2019), which is a 5.5tb write-once cartridge.
This is a medium designed for things like tape robots
They call it "PetaSite", because if you go to the biggest variety, you can fit 2.9 petabytes in a rack.
I mean, if you build a backblaze pod (6.0), that's 60 drives in a 4U chassis.
with 8tb drives you fit 4.8PB per rack, and you can buy 16tb drives today... that's a 9.6PB rack
having 600 spinning drives + 10 servers + cooling running 24/7 is not going to be cheap on the electricity.
It's like how the SEC used to require broker-dealer records be recorded on WORM discs
They can be like "hey, just buy this thing, and you've got PETABYTES worth of data storage that you can trust wasn't changed"
You're not having some person who has the job to burn the DVD-Rs and make sure they're put away in the right places and such.
So less than a terabyte! that's not much, really...
A thousand CD-ROMs? that's more storage than God would ever need.
the only time humans have to deal with them is when they load in more discs or pull discs out to shove them in offline storage (well, offliner)
A lot of people are like "wait, those are real?" because they think I just mocked up some giant cardboard fake discs or something.

So Sony got a bunch of storage in one cartridge by building a special drive that pulls out one of 13 blu-ray discs, right?
Sony developed blu-ray, so it only makes sense
1. I don't have a drive, and this is because they're very expensive. I'd like to have one, if only to take it apart and see how it works.
The mechanism for loading the individual disc has to be neat
Like, I've opened them in the first hour of a 2 day conference and spent the rest of the time trying and failing to put them back together
once by me, when I first got it
once by my wife, when she wanted to show someone at the exhibit...
Fun fact: as soon as it showed up on screen I started going "oh god don't open it don't open it don't open it don't FUCK!"
I was right.
you put the cartridge in, and the top half stays there.
the bottom half is lowered down to clear it from the top half, then there's a servo that pokes the individual disc out into the drive.

So I got out some CF cards and noticed something odd about this one. Do you see the weirdness?
How the fuck is a CF card "USB Enabled"?
So CF cards are a weird beast that act as either a PCMCIA card or an ATA/IDE card depending on a mode pin.
They're definitely not USB.
And it's not like that weird SanDisk card I have which you can fold in half and plug it in as a USB device.
It turns out the reason for "USB Enabled" is because it's a Lexar drive from the jumpSHOT era.
This is a normal CF card in most cases, you can use it in normal CF card readers and such

Flip it over, bend it in half, and now you can plug your SD card right into a USB port pic.twitter.com/jeBefP2xU1

Machine translation can be a wonderful translation tool, but its uses are widely misunderstood.
Let's talk about Google Translate, its current state in the professional translation industry, and why robots are terrible at interpreting culture and context.
Straight to the point: machine translation (MT) is an incredibly helpful tool for translation! But just like any tool, there are specific times and places for it.
You wouldn't use a jackhammer to nail a painting to the wall.
Two factors are at play when determining how useful MT is: language pair and context.
Certain language pairs are better suited for MT. Typically, the more similar the grammar structure, the better the MT will be. Think Spanish <> Portuguese vs. Spanish <> Japanese.
No two MT engines are the same, though! Check out how human professionals ranked their choice of MT engine in a Phrase survey:

When it comes to context, the first thing to look at is the type of text you want to translate. Typically, the more technical and straightforward the text, the better a machine will be at working on it.

1/OK, data mystery time.
This New York Times feature shows China with a Gini Index of less than 30, which would make it more equal than Canada, France, or the Netherlands. https://t.co/g3Sv6DZTDE
That's weird. Income inequality in China is legendary.
Let's check this number.

3/The World Bank report has a graph in which it appears to show the same value for China's Gini - under 0.3.
The graph cites the World Development Indicators as its source for the income inequality data.
4/The World Development Indicators are available at the World Bank's website.
Here's the Gini index: https://t.co/MvylQzpX6A
It looks as if the latest estimate for China's Gini is 42.2.
That estimate is from 2012.
5/A Gini of 42.2 would put China in the same neighborhood as the U.S., whose Gini was estimated at 41 in 2013.
I can't find the <30 number anywhere. The only other estimate in the tables for China is from 2008, when it was estimated at 42.8.
