Hey, Google go b-tree implementation author here. A few important things: - this implementation was done by me while I worked at Google and needed a good ordered tree. It is not an…

I've worked at Google for a while, and a few years ago I wanted to release an open-source project. Since the code was going on Git, it made sense to throw the design there too, so …

It's not a (provable, guaranteed) CP system. Bitcoin attempts to provide a global consensus across a large number of actors, but its attempt is based on proof of work, specifically…

> Under Linux, some SECCOMP initialization and capability dances having to do with dropping root and closing off privilege-escalation attacks as soon as possible after startup. I w…

Hey, would you mind if I added a link to this article from gopacket's README.md?

I think the reason we're getting faster performance is that we tend to have packets clustered on disk, as you've surmised. Since packets with particular ports/IPs/etc tend to clust…

I blame blissful ignorance: I'm not at all familiar with DPDK. I'll definitely read up, though! I wonder if O_DIRECT writes can happen from DPDK memory space? If not, we don't gain…

Hey, great questions! Query Performance: Right now, we've got test machines deployed with 8 500GB disks for packets + 1 indexing disk (all 15KRPM spinning disks). They keep at 90% …

Offline jobs are an interesting idea, but they weren't what we were really thinking of. Instead, we use stenographer more like a database of recent traffic. Consider this as a simp…

No corrections necessary, you're right on the money. This is a 20% project. While it's one we plan to use internally, it's not a "supported" Google product. It's just another open-…

Hey, thanks! If you have any additional questions about the design process, internals, etc, feel free to ask. I'm the primary author of the project, and I'll be refreshing the HN p…

Excellent! I'll try to send you a pull request sometime Monday or Tuesday.

I run an open-source Go library that also does packet capture/encode/decode ( http://code.google.com/p/gopacket ). Would you be at all interested in adding results for gopacket to …
