Putting the Secret Service's nonsense framing aside, it's a pretty cool discovery. Those black boxes are SIM gateways which you plug sim cards into and they act like virtual cell phones. They then route the access over the internet so people can use the sim cards from anywhere in the world.🧵

In some weird uno reverse type of way a company has offered to pay me in "exposure" on my own blog for reviewing their product.
Thanks, vendor of [#database corruption recovery tool], but, as tempting as being paid with the opportunity to write a review for your product sounds, I'll have to pass.

Leopards, meet faces...
there's an episode of The Simpsons where Marge tries to get a violent cartoon pulled from the airwaves, only to discover that the people backing her aren't going to stop at just the art that *she* doesn't like, and that supporting artistic freedom means accepting discomfort.

It aired in 1990.

Upgrading from older versions? You'll need this ONE time:

```
Install-Module dbatools -Force -SkipPublisherCheck
```

After that initial transition, you won't need SkipPublisherCheck again since our cert keeps the same subject and root CA for version 2.5.5+ onward.
