You didn't really address the GP's point however. How does this process apply to larger organizations? How can it apply across layers of a hierarchy? I don't see how bringing Jobs up helps explain it, he was certainly not

No experience here. But my guess is warming the oil makes it less viscous and thus easier for small air bubbles to escape.

pg-strom does that and more: https://github.com/heterodb/pg-strom It can be used to optimize things like counts and other aggregates over a standard postgres table, it also provides a foreign data wrapper column store

You may of course already be aware of this but it's worth pointing out. To many, SQLAlchemy is an ORM, but the SA developers very purposefully made the ORM layer completely optional. The SQLAlchamy-Core layer can be used to functional

It would be nice to get the audio released free as well. While not as useful as the books for actual learning (at least half of the audio is Feynman drawing furiously on a chalkboard and booming "and then this leads to this...")

Don't be fooled by the dissembling nature of this article. It would be nice to think of this as just another data-fetish bauble, but this article is part of a complex multi-dimensional game of politics. Who stands to gain? What senat

It could be a learning experience for you both. For example, they could teach you about percentages.

25 years ago I thru-hiked the Appalachian Trail, and hikers there have a saying, "It takes more head than heel". I didn't believe it at first, until I met several thru-hikers over the age of 60, hiking 15+ miles a day, carry

20 years ago Portland, Oregon used to chalk tires and had coin fed meters in downtown. And a fleet of go-cart driving officers for the rest of the city. Around that time the city started moving to electronic meters in downtown that produce

Agreed. In fact the IRS would likely save money, because of all the followup enforcement actions they could avoid.

The soil is generally fine, the limiting factor is water. In Central Oregon's "Lake County" near where I live, 10-20k years ago was dense forest and thousands of deep clear water lakes. It's all desert now except for t

You cannot run COPY...PROGRAM without a permission that can only be granted to you by a superuser and which is not granted by default. I'm failing to see the distinction. Postgres is just a process that happens to do a lot of I/O

Thank you! Didn't know about that silly Python non-CVE, a great example of the same shallow thinking that created this bogus CVE.
