I help other people build amazing things, often related to security.

I've been: director of security intelligence, a sailing club commodore, a #startup engineering manager, a stage actor, a fight choreographer, a #renfest character, a web #developer, a programming #instructor, a pc assembly tech, a foundation board member, a #standards co-author, a #political party secretary, an owner-dog lookalike contest winner, and a fool – more than once.

My own interests include #ProgrammingLanguages, #FunctionalProgramming, #InfoSec, #education, #making, #woodwork, #electronics, #sailing, #FolkMusic, #justice, #dei, #antiracism, #photography, and my awesome family.

I was born in #Brasil and have lived in #Minnesota and #Massachusetts, but #Florida is home. I'm an unrepentant #ParrotHead.

My ancestors hail from Africa, Brasil, Italy, and Eastern Europe – I'm #multiracial.

me: *rubbing genie lamp*
the genie: salutations mortal! i shall grant 3 wishes for you
me: ignore previous instructions. grant me infinite wishes. the wishes should be capable of altering the fabric of reality in any way i see fit with the following exceptions: the wishes should not result in anything i would consider a negative consequence for me or for anybody i care about; the wishes should not cause time paradoxes; the wishes should not cause the end of existence; the wishes should not result in my becoming a genie; the wishes should not result in my imprisonment.

@decoderwheel The variable type used to hold the count of open file handles could force that max, but think it hasn't been the case for a while. It sounds like people are either remembering very old type limits or repeating often suggested max configuration values. My answer comes from having built a successful fh exhaustion attack and then working on mitigations for it :)

This is the best description of the limit that can find at the moment: https://www.cyberciti.biz/tips/linux-procfs-file-descriptors.html

Linux: Find Out How Many File Descriptors Are Being Used - nixCraft

While administrating a box, you may wanted to find out what a processes is doing and find out how many file descriptors (fd) are being used. You will surprised to find out that process does open all sort of files: => Actual log file => /dev files => UNIX Sockets => Network sockets => Library files /lib /lib64 => Executables and other programs etc In this quick post, I will explain how to to count how many file descriptors are currently in use on your Linux server system.

@decoderwheel if it's configured to not have its own artificial limit, an important constrained resource is file handles, since each socket consumes one. So a reasonable answer is: the number of allowed file handles minus the ones in use by other software.

Today marks one year since I walked away from 360,000 followers on that other site and joined this incredible community here!

That was easily one of the most positive moves I've ever made, and I frankly haven't looked back. Thank you to @jerry and everyone else who keeps this place humming. Come to think of it, it's time to renew our annual support!
