Talking about @ConDaysEU. Don't miss to check about all the news and stuff going on on Twitter.
@ConDaysEU and #CDS22 are good starting points to follow up.
I had the pleasure to deliver multiple talks.

Very excited that XRP wins Jay Lepreau Best Paper Award 🏆 at #osdi22! XRP (open-sourced) is the first system that adopts #Linux #eBPF 🐝 to reduce kernel software overhead for storage. (1/9)
With new storage technology like 3D XPoint, storage devices are getting much faster ⚡️. As a result, kernel software is becoming the bottleneck for storage! See the breakdown of the average latency of random 512B reads. (2/9)
One extreme way to address the kernel software overhead is to bypass the kernel. However, kernel bypass comes with several issues 💣, such as no fine-grained access control and poor CPU utilization. (3/9)
This month's (June 22) updates from @AquaSecTeam Open Source Team - features, content, news and more 🧵
@AquaSecTeam One of the biggest news this past month was that Trivy now scans #kubernetes ⎈ clusters - through the CLI or a native Kubernetes Operator!
More and more people are experimenting with #eBPF (great!), but it seems that not everyone knows how bpftool can help manage BPF objects. I'm starting a series of tweets to help spread the awareness. Expect about one tweet a day.
[1] The sources for bpftool can be found in the Linux kernel repository. git.kernel.org/pub/scm/linux/…
To compile it: cd tools/bpf/bpftool; make; (make install; make doc; make doc-install)

[2] "bpftool prog show" is used to list all BPF programs currently loaded on the system (loaded ⇏ attached).
"bpftool prog show id 27" shows just the program of given id (ids are displayed on the left column on the list).
"bpftool prog list" is an alias, does the same thing.
