Support me by buying from my eBay store:
BTW in case you didn't notice, tomorrow at 1777777777 it's going to be 1777777777 epoch time.
Copy Fail is a very serious root escalation vuln released on Wednesday that requires your attention. More details and the fix at https://copy.fail/ and be sure to reboot after you've patched.
Had the fortune of meeting Michael Elkins (left), the creator of the mutt email client, today while at the Information Sciences Institute.
Be careful when you search for PuTTY or recommend the PuTTY SSH client to people. You want to make sure you give them the correct address. Major search engines still give the wrong one. The putty dot org address was never official and now has been repurposed for anti-vax crap https://www.theregister.com/2025/07/17/puttyorg_website_controversy/
echo you can shuffle up the words of a sentence by using xargs twice like this | xargs -n1 echo | shuf | xargs
whois dirtyfrag\.com | grep -E "(Country|State|Creation)"
Interesting domain registration I noticed last night while writing up an advisory.
Vim users: If you'd like to highlight the whole line the cursor is on:

Being able to do stuff like this is what makes the command line pretty special:
ssh 192.168.0.15 'sudo dd if=/dev/sda bs=1M status=progress' > backup-old-drive.img
Bad UX design demonstrated in one form field.
sudo su -
alias facts='timedatectl set-ntp'
facts false
timedatectl set-time "1984-01-15"
Set your system date to January 15, 1984, and not for the Mac commercial. Just run 'facts true' to return to reality.
Today someone asked me if I could open an Excel spreadsheet and I kinda chuckled at the question. But, it was a good reminder that even if the bar is low, it's not zero.
I made a podcast episode to welcome all the new Linux users to the community and invite them to participate in the community.

It's funny how humans complain about AI hallucinations when humans make shit up all the time.
Is the post-mis-information age going to be any better?

@realcainmosni@mastodon.me.uk See, this is why I didn't give a "human readable" time. People argue about everything.

@dat@social.g33ky.de Apparently putty.software is the new official address run by the putty team, just hasn't caught on yet.
Remember to be a good user, or you might end up with /dev/null under the tree.

Replying to
@mariusor That's a bad assumption to make. Think of all the code you run as a normal user that could potentially exploit this. Exploits aren't just about scripts you're tricked into running, they can be embedded in trusted programs with weak code review practices.
