>Sargent also said Kroger would refocus its e-commerce efforts on its fleet of more than 2,700 grocery supermarkets because it believed that its stores gave it a way to “reach new customer segments and expand rapid delivery capabilities without significant capital investments.”

Someone didn't read the 26 year old Webvan case study at CEO-school.

I'm not a geophysicist but it doesn't seem like impermeable rock would "inflate like a balloon" and even if it did, that seems like it would be a pretty bad thing for the surrounding countryside. Given that water infamously doesn't like to compress, I'm at a loss for how this thing actually works.

Does anyone have a better explanation than this article?

If you pressurize something "incompressible" like water under a cap of impermeable rock you are to still compressing the water and compressing the surrounding rock. The whole industry of fracking operates on compression rock to the point of fracturing it and forcing open the cracks. At 600-1300 bar water compresses 3-6%. It's the "equivalent" of a reservoir at the height of everest or higher.

Where did the "libREated" in the title come from?

You can assume that for any subject other than CS, unless someone specifically mentions their credentials in the field, most commenters won't know what they're talking about. Hacker News has a reputation for "aggressive ignorance" outside of its wheelhouse.

Remember, HN isn't exactly checking anyone's CV at the door. All it takes to post here is knowing how to fill out a web form. The culture here tends to believe the simplistic design somehow draws deep technical intellects like moths to a flame but it really doesn't.

I get that, what's hard is if my made up chip designer is commenting about UI coding or networking topology or something closer to HNs heart.

The thing that's hard about the intellectual curiosity part is knowing what comments are from actual experts and what are very smart people opining outside the edges of their circle of competence - while still sounding smart.

There was a discussion here where a professor with a specialty on the underlying subject was 'corrected'/crowded out by very detailed comments that sounded cogent, had buzzwords in them but ultimately were incorrect.

Seeing that makes me wonder about the discussion here on topics I know nothing about. Vetted flair for subject matter expertise for users would help. I'm still interested in what a chip designer has to say about astronomy but it would make it easier to weigh the contribution.

I was one of those weird users who used the 64-bit version of Windows XP, with what I'm pretty sure was an Athlon 64 X2, both the first 64-bit chip and first dual-core one that I had.

We tried Windows 2000 Professional for the DEC Alpha for a GIS system in the late 90s. Suddenly made the $5000 PCs that could run it seem cheap.

> On March 16, 2016, AP reported that in February 2009, secretary of state Hillary Clinton also wanted a secured BlackBerry like the one used by Obama, but that NSA denied that request. A month later, Clinton began using a private server, located in the basement of her home, to exchange e-mail messages with her top aides through her regular, non-secure BlackBerry. Later it came out that this rather risky solution was also used for sensitive messages.

A good reminder how IT departments need to provide solutions that actually work and are accessible to everyone. If not, "shadow IT" will emerge, rather sooner than later.

And Clinton was Secretary of State, not some low level clerk.

And the lesson every us pol seems to have learned is "use signal, use protonmail."

> Unfortunately, news of the 1582 promulgation had not yet reached the developers of Lotus 1-2-3, so they assumed that 1900 (being a multiple of 4) was a leap year.

Joel Spolsky mentions a more charitable take on this from Ed Fries:

> Lotus had to fit in 640K. That’s not a lot of memory. If you ignore 1900, you can figure out if a given year is a leap year just by looking to see if the rightmost two bits are zero. That’s really fast and easy. The Lotus guys probably figured it didn’t matter to be wrong for those two months way in the past.

Am I remembering it wrong or did Microsoft use an undocumented call in excel to grant it more memory than was possible for early competitors who didn't also write the OS?
