After weeks of procrastination, I finally wrote the first post in a series explaining SPy.
This one focuses on why Python is slow—the gap between what the language allows and how it’s used in practice—and hints at how SPy aims to fix it:

We finally decided to write out how we use XDP in our network plane for live network migrations and more specifically to process outgoing packets!
This is the first in a series of promised deep dives into how Loophole's live migration tech works!

An eBPF Loophole: Using XDP for Egress Traffic
XDP is Linux's fastest packet processor but only handles incoming traffic. We found a loophole in how the kernel determines packet direction to make it work for outgoing traffic too!

Using XDP for Egress Traffic
XDP only works for ingress. We found a loophole that lets it work for egress. Here's how we did the impossible.

The entire reason Anthropic named a feature “Skills” is so they could file bugs under “Skills Issue” and you can't convince me otherwise

everything is a compiler if you believe
software can only transform data into other data, and everything we view as a higher capability is just composing transformations
imo once you are fully pilled on this, the idea of defining the structure & semantics of the data on either side of the transformation as well as possible seems obvious

🕶️🤌 Nice broker you have there, it would be a shame if someone put #wasm in it
In-broker #Wasm transforms in @apachekafka with #Chicory and some light low-level patching 🧐
I hope you enjoyed part 1, because this is part 2 😎
