comment How does Karma's open WiFi network successfully protect its users?
@AndréBorie Having set up a wireless network in exactly that manner, I can tell you why it isn't generally done: Windows. In particular, Windows 7 and prior versions refuse to accept the RADIUS certificate unless they're pre-configured to accept or ignore it, before you ever connect. This isn't really an issue with Windows 8 and later, but there's still a lot of Windows 7, and even some Vista and XP out there.

comment Personal Information shows up in Google Search from a mailing list
@JAB Taking care of the original will also take care of most caches over a short time; and archives such as archive.org's Wayback Machine aren't really searchable.

comment Why is leaving a passworded SSH over the internet so bad?
@TOOGAM It sounds like you are unaware that OpenSSH already uses privilege separation and has done so for over a decade.

comment Why is leaving a passworded SSH over the internet so bad?
I found that merely hardening sshd a bit killed the vast majority of the bots out there, making them unable to communicate with the server. There is no longer enough brute force traffic to trigger fail2ban!

comment What can I do if I discover that my password hash has been leaked in pastebin?
This was probably wallofbricks.com , which is run by one dwalton76, and which domain name was registered a week before his first login...

comment Risk of tampering when hardware shipment is delayed
I've been shipping and receiving packages (e.g. from eBay) and I've noticed a lot of delayed packages. It's probably not just you. This seems to happen every December.
