I think biculturalism offers the advantage more than just language.


That’s funny because I produced a remix with an original beat I composed over a 2pac acapela, and the number one comment I always get is that the song gives people chills and goosebumps.

Sure enough, it does give me chills pretty fast. Do you reckon you could put it on Spotify or at least publish a higher quality file? The MP3 download seems dead

(Nvm for Spotify - it's there just not in my country :( )


Hi are you the author? What would I need to study to be able to do stuff like this? Are there any specific books or courses you’d recommend? Thanks


If you have any questions about eBPF I'd be happy to answer them, I work on the kernel portion.


Is it possible to do stateful stuff like NAT in eBPF without having to reimplement conntrack? I think cilium does it but has to reimplement in using maps.


Not in an XDP program, it runs almost immediately after a packet has been rxed, and yes, Cilium does this by reimplementing similar logic in BPF. You could request new helpers for a SCHED_CLS type program though. The helpers don't exist today, but eBPF is use case driven, and if there is a good use case for it, it can go onto the roadmap.


Thanks! I did find this: https://lists.linuxfoundation.org/pipermail/iovisor-dev/2017... and some references to bpf_skb_ct_lookup/bpf_xdp_ct_lookup -- are these fully baked?


There isn't much in the way of books that really take you from design to implementation when it comes to CPU design but the nand2tetris book is a good place to start.


That is a broad question, going through a FPGA tutorial buying a small dev board. My first project was something similar to this, but a lot simpler.
