HN Discussion

I always gripe about Python not having useful (i.e. performant and with adoption) built-in array type and Numpy doesn't distinguish "vector of vector" from "matrix", but this still surprised me.

Some combination of the feeling of frustration and injustice that really pushes my proverbial buttons.

In this particular case, the "$5 charge on my phone bill" turned out to be literally hundreds of recurring subscription invoices that Stripe disabled collection for because, apparently, those subscriptions required "location inputs".

Generally speaking, I don't blog much anymore, and the last thing I wa

How to create a Bootable MacOS Recovery USB from Linux

If your Mac is out-of-order or you otherwise cannot download macOS from the App Store, you can still create a bootable OS X recovery USB, and you can use that to create an Installer USB.

The downloads used in this process are legal and freely avaliable - including disk images directly from Apple's IT support pages, and open source utilities for extracting and converting pkg, dmg, and HFS+.
