I didn’t know binaries could embed LLDB-specific bytecode for formatting custom data types nicely in the debugger, as shown in this swift-collections PR: https://github.com/apple/swift-collections/pull/607. The code also uses fancy new Swift features to place the bytecode in a specific linker section:

@⁠section(".lldbformatters")
@⁠used
let __BasicContainers___RigidArray______formatter: (UInt8, UInt8, …, UInt8) = …

Being a programmer is almost exactly like being a builder, except you show up to work with a toolbox full of spanners and power tools you know how to use dangerously and improperly, your education was in assembling Lego, the worksite is a skyscraper made of mud, and your colleagues think you’re being intentionally obtuse when you tell them there’s no way of knowing how long it will take to attach a windmill made of cheese.

Me: why is everything so dusty?

People who can adult: you have to dust.

Me: what, like annually?

Adults: no, more like weekly.

Me: that can’t be right.

For some time @securelyfitz and I have been working on a new hardware security tool. It is called epic-erebus. It is a tiny m.2 WiFi module sized FPGA board allowing the access to the PCIe interface. If you remember the slotscreamer, this is the evolution of that idea. It can do a lot more in the small form factor and FPGA on board. We just published our pre-campaign page. You can sign up for updates for when the campaign launches some time next year. https://www.crowdsupply.com/securinghw/epic-erebus #EpicErebus #fpga
