Hi. I’m back on Twitter/X after a long hiatus.

Things have changed quite a bit since I’ve been around here, but I’m looking forward to reconnecting with others.

I am super excited to announce that I have started a new role as “Head of Open Source Community” at @CtrlIQ!

I’m diving into @rocky_linux, @SingularityApp, @OpenELAorg, and Warewulf in the coming weeks to see where I can help.

If you see me lurking in your community, say hi :)

[Apptainer (formerly Singularity) @SingularityApp]

@4NY4SCII Yep! Know it well. :-)

Use the LinuxFoundation community version called Apptainer and good things will happen. :-)

It’s a bit late, but how did it go?

[Apptainer (formerly Singularity) @SingularityApp]

@AnthonyASnead Love this! …. Curious why you avoided Singularity/Apptainer before?

@unixterminal We looked for RedHat, couldn’t find them. What booth number are they at?

Thanks!

@shinji_kono That is so wonderful to hear, thank you for the feedback!

@bmsacchi And as much as I love Apples, especially sliced with a bit of lemon juice, or on a peanut butter and jelly sandwich, Apptainer is even better!

Here is a great blog on how to upgrade Singularity(CE) to Apptainer from @CtrlIQ:

IMPORTANT SECURITY NOTICE:

NIST/NVD has classified CVE 2023-30549 as a HIGH risk which affects all versions of Singularity(CE).

Default installations of Apptainer >= 1.1.0 are safe thanks to its secure and unprivileged (rootless) execution model.

Our very own Dave Godlove putting on a clinic! Here's a quick snap of our recent onsite training of @SingularityApp with a CIQ customer. Awesome job Dave!!

SECURITY ANNOUNCEMENT! All versions of Singularity and SUID-enabled Apptainer (< 1.1.8) increase the severity of issues like CVE-2022-1184 (which will NOT be fixed upstream by RHEL7 and compats).

This is why Apptainer no longer runs as SUID by default.

Did you know that you can easily use @graph_tool with @SingularityApp?

Singularity/Apptainer lets you run containers in HPC clusters *as a regular user*.

This means you do not have to ask your sysadmin to install software for you!

Thank you!
