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.

BTW in case you didn't notice, tomorrow at 1777777777 it's going to be 1777777777 epoch time.

The Copy Fail is a very serious root escalation vuln released on Wednesday that requires your attention. More details and the fix at copy.fail and be sure to reboot after you've patched.

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. www.theregister.com/2025/07/17/p...

Had the fortune of meeting Michael Elkins (left), the creator of the mutt email client, today while at the Information Sciences Institute.

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.

I made a podcast episode to welcome all the new Linux users to the community and invite them to participate in the community. hackerpublicradio.org/eps/hpr4536/...

Is the post-mis-information age going to be any better?

Bad UX design demonstrated in one form field.

It's funny how humans complain about AI hallucinations when humans make shit up all the time.

Vim users: If you'd like to highlight the whole line the cursor is on: :set cursorline I just used that when examining package output from dpkg -l so that I could easily see which description matched each package.

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

All I wanted to do was copy a file.

The Daemon In The Castle

This Minecraft MMO server has "command line terminals" in it. Non-functional, but I approve. play.stardew.net

Couldn't help but notice the lunar eclipse tonight at least in eastern time zone is π (3.14159) as in March 14th in the 159th minute of the day (2:39am)

I tried to do standup comedy once. But, by the time I finished editing the joke, the audience was already walking out and my computer was all over the floor.

I had forgotten how unixy the Amiga shell is.

If you mistakenly use curl like nc like the following: curl www.example.com 80 the port number ends up being treated as an IP address of the form 0.0.0.N. So if you see traffic destined to 0.0.0.80, 0.0.0.22, etc. on your network, it's probably someone messing up their curl command.

Today I learned that not only Libreoffice didn't have a unique() function until recently, but apparently Excel didn't even have it until 2018. This is like 30 years later than you'd expect spreadsheets to implement it. Unix had it in 1982 as Brian Kernighan shows here www.youtube.com/watch?v=tc4R...

If you're concerned about how your use of wildcards and brace expansion will be interpreted by the shell and passed to the program, you can usually replace the command name with echo first to get a list of the args that will be generated: echo Photos/\[Conference\]-*.{jpg,mp4}

If you're not sure what type of data is in a gzip, bzip2, or xz format file, one way to find out is to pipe its decompressed output into the 'file' command: gzip -dc unknown-gzip-file | file - It will tell you the type of file data that is inside. The -dc options also work with bzip2 and xz

I ran this yesterday to solve a CTF. It should have been called a WTF. xxd -r data.txt | gzip -cd | bzip2 -cd | gzip -cd | tar x -O | tar x -O | bzip2 -cd | tar x -O | gzip -cd

Every Unix is sacred, every Unix is best. Every Unix is different, when you run ps.

printf "\e[34;1m . .\n( \\__/ )\n \\ /\n (_/\_)\n\e[0m"
