@rebuildcon.bsky.social isn't just me & @dhardiker.bsky.social. Meet the steering team. Audrey Neveu is a Staff Engineer & Java Champion with 15+ years of writing Java, the kind of person who knows exactly what a developer conference should feel like from the inside.

This is extremely helpful. Do this! I won’t read LLM generated stuff - unless I wrote the prompt myself. OTOH, I’ll happily read you! (Also please do this when you submit a PR, rather than blurting out an LLM summary that noone will read)

Ha, so that’s why they’re called hail“stones”. Not even the biggest one, just the first I could grab.
Open palm holding a 4-5cm hailstone, ragged edges, like some mutant ice cube.
In the background, a flooded balcony with heaps of ice in the potted plants.

Being an Open Source Contributor™ has long been perceived as a badge of honor. But today, people pointing their LLM at some random issue that they have no interest in, without reading or understanding the output... Some of it gets merged, so what is "I contributed to X" worth anymore?

The tradeoff security vs features in the age of LLMs is fascinating. Everything moves fast, and you have to deliver to keep up. This creates more attack surface. Meanwhile, security researchers (and attackers) produce a staggering amount of reports, that you MUST carefully review, slowing delivery.
