use a VPN & https, which would reduce the attack surface, but it’s not ‘perfect’.
Update from Forbes
Lots of stuff updated. Lots of stuff not. This is where it pays to know what you have in use and monitor your suppliers for notices.

When a responsible person discovers a security issue, disclosing it properly is difficult
Uses Tesla’s policy as a good example of how companies should do this
“This is not hard stuff and it basically amounts to text on a page. Consider whether your own organisation has something to this effect and is actually ready to handle disclosure by those who attempt to do so ethically. Listen to these people and be thankful they exist; there’s a whole bunch of others out there who are far less charitable and by the time you hear from those guys, it’s already too late.”

The Btrfs file system has been in Technology Preview state since the initial release of Red Hat Enterprise Linux 6. Red Hat will not be moving Btrfs to a fully supported feature and it will be removed in a future major release of Red Hat Enterprise Linux.
The Btrfs file system did receive numerous updates from the upstream in Red Hat Enterprise Linux 7.4 and will remain available in the Red Hat Enterprise Linux 7 series. However, this is the last planned update to this feature.

NOTE: these are SHA-1 hashes, not the raw passwords: 320,335,236 to be precise
Password checking page – that same URL has links for downloading the hashes
To unzip the files, you need p7zip. Command to extract is: 7z x pwned-passwords-update-1.txt.7z
to generate a sha1 hash, Dan used: ‘sha1 -s TechSNAP’ – SHA1 (“TechSNAP”) = c6586a62febc8706d814fe28fe397e9dca146992. Use “tr ‘[a-z]’ ‘[A-Z]'” to upper case.

No more periodic password changes
No more imposed password complexity
Mandatory validation of newly created passwords against a list of commonly-used, expected, or compromised passwords.
We recommend you use a password manager, use a different password on every login

The enterprise disks also use more power: 9W idle and 10W operational, compared to 7.2W idle and 9W operational for comparable consumer disks.
If you have one or two spindles, that’s no big deal, but each Backblaze rack has 20 “storage pods” with 60 disks each. An extra 2.2kW for an idle rack is nothing to sniff at.
Other HGST models are also continuing to show impressive longevity, with three 4TB models and one 3TB model both boasting a sub-1 percent annualized failure rate.
