共 25983 篇eBPF Looks Illegal: running your code inside the Linux kernel
A visual walkthrough of Linux eBPF. It goes through the basic pipeline: write a small C program, compile it with clang, load it with bpf(), get it past the verifier, JIT it, attach it to a kernel event, and read data back through maps/ring buffers.

Tell HN: I managed to unsubscribe from Adobe CC without being charged
I had an educational Adobe CC subscription that went from ~£25 per month to ~£67 recently. When I went to cancel after I realised I didn't really use it that much and could just use Affinity, I was shocked to find out that I was going to be charged ~£250 because although I pay monthly I was in a yearly contract. (I did know that, which is on me, but it's easy to forget that because of the payment structure). It's a serious barrier, so I looked at the other options, and you're able to transfer to
