Cybersecurity weather person and award winning shitposter. Shitposting is an anagram of Top Insights. You may be surprised to know I am not representing my employer here and these are not their opinions.

I have Direct Messages disabled - you can send them, but I will never receive them.

David Chisnall (*Now with 50% more sarcasm!*)
@[email protected]

I am Director of System Architecture at SCI Semiconductor and a Visiting Researcher at the University of Cambridge Computer Laboratory. I remain actively involved in the project, where I led the early language / compiler strand of the research, and am the maintainer of the Platform.

I was on the FreeBSD Core Team for two terms, have been an LLVM developer since 2008, am the author of the GNUstep Objective-C runtime (libobjc2 and associated clang support), and am responsible for libcxxrt and the BSD-licensed device tree compiler.

Opinions expressed by me are not necessarily opinions. In all probability they are random ramblings and should be ignored. Failure to ignore may result in severe boredom and / or confusion. Shake well before opening. Keep refrigerated.

Warning: May contain greater than the recommended daily allowance of sarcasm.

Most of my money comes from contract work for public utilities around the country, but I also provide remote tech support to small business and SOHO clients, mainly (but not exclusively) in the USA.

I do a fair amount of custom work for people when a loved one dies: unlocking computers, data recovery, and account recovery (Advice: keep paying their cell phone bill until you've got all their data back).

Also, personal cybersecurity for journalists, TV reporters, politicians down to the City Council level, and political candidates. TV stations: contact me for contract pricing for your entire news team.

Use fifonetworks.com/contact-us/ for questions or to schedule service. It's just me. You'll be communicating directly with me.

"not helpful" @LucasWerkmeister

All my opinions are that of my employer but they don't know it yet & I am not telling you were I work. Apropos: If you need some idiot to kick computers for purposes of making them secure hmu, this job fucking sucks (vulnerability management, automation/engineering for your soc/isrt, ...).

PFP by a lizard that I am pretty sure transitioned at some point but I kinda lost contact with around the same time so I might only know their deadname & at this point it's too awkward to seek them out & ask. So instead I am going to credit them by their last discord handle I am aware of: fuck, md
