GPT along with most filesystems store a bunch of stuff at random places around the disk, for many filesystems it's even configurable. The most usual problem with your approach is recreating a set of partition tables exactly matching th

It is still bad advice, zero filling an SSD is not nearly the same as erasing it due to the presence of large (up to 10% or more of the drive) overprovisioning areas present in all devices, ignoring the permanent wear zero-filling the drive

This option is horrendously inefficient on most modern drives. For many SSDs, issuing a secure erase request is an almost instantaneous process as it only requires the drive to generate a replacement encryption key, and need not even entail

The worst experience I had with this involved 4 customer service representatives simply hanging up (after a 30+ minute wait) after exhausting their script. I simply recorded the final call, stopping paying the bill, and sent the documentati

Substantively, this is a battle between a US media powerhouse and a sovereign nation over control of its local media. This isn't "ideological flamewar", it is an inescapable reality underpinning the case.

I like the idea of flipping DIMMs to get capacity and processing improvements, and also the thought that mass-produced memory with this tech could potentially significantly reduce the cost of AI hardware through commoditization

The inverse of effeminate by definition is butch, I purposefully avoided using it as it invokes yet more popular and inaccurate gay stereotypes that in no way capture the folk I was describing

> effeminate male > gay son This is a dangerous stereotype that is equally harmful to people of any sexuality, I'd encourage you to correct it. Most of the gay folk I know personally tend towards the athletic end of the spectrum
