Next NYC*BUG: 2026-06-03

Let's review some OpenBSD mitigations, with Brian Callahan
2026-06-03 @ 18:45 local (22:45 UTC) - Backroom of Brass Monkey 55 Little West 12th St
How do we know that security mitigations actually work? How often should we review code to ensure they are continuing to provide?
Following two recent publications, let’s explore some of OpenBSD’s anti-ROP mitigations. We will explore what they do, how to test they work, how to port them to other operating systems, and how to understand larger questions about security mitigations. You’ll leave having a deeper appreciation for OpenBSD’s sustained security track record.
Brian is a long-time face in the *BSD world. While he claims semi-retirement from OpenBSD development, in reality he probably spends even more time on it getting students excited about the BSDs. He is the Director of the Monmouth University Cybersecurity Research Center, where here leads quantum cybers ecurity and other security research.
Nearest NYC Subway is the 14th Street/Eighth Avenue station L, A, C, E.

Some relevant reading for the meeting might be Stephen’s 1978 piece in
The Bell System Technical Journal entitled “UNIX Time-Sharing System:
The UNIX Shell” https://archive.org/details/bstj57-6-1971 (Bell System
Technical Journal, Vol 57, No 6, 1978).

Steve Bourne is internationally known for his work on the UNIX operating
system. During his career he spent 20 years in senior engineering
management positions at computer systems and networking companies. These
included Cisco Systems, Sun Microsystems, Digital Equipment and Silicon
Graphics. Since 2000 he has been Chief Technology Officer at El Dorado
Ventures (now Rally Ventures) in Menlo Park, California.

He is past chair of the ACM Queue board, a magazine that he started in
2003 for software practitioners.

Steve spent nine years at Bell Laboratories as a member of the Seventh
Edition UNIX team. He designed the UNIX Command Language sh or “Bourne
Shell” which is used for scripting in the UNIX programming environment
and he wrote the adb debugger tool. His book “The UNIX System” was
widely read and published in 1983.

Would you like to get more out of bsddialog(3)?
BSDCan has a tutorial for that:

Introduction to TUI Programming using bsddialog with Benedict Reuschling
Thursday 2026-06-18: 13:00 - 16:00

Shell scripts have a bad reputation when it comes to usability and eye candy. Modern users find a blinking cursor on a a black screen leaves a lot to be desired when having to interact with a shell script. In this tutorial, we will create shell scripts that look like a GUI application: with buttons to press, input fields, select boxes and animated progress bars. These so called TUI (text user interfaces) programs still use shell script functionality as the backend, but are lightweight enough to not introduce too much overhead. Users will appreciate the ease of use of your shell scripts and you can rely on them to give you the data and visualizations you to need. At the same time, the TUI application is not difficult to learn and implement into existing scripts.
