Speed up your ROS snap builds

A while back I wrote a post about distributing a ROS system among multiple snaps. If you want to enable some sort of add-on story, you need to have multiple snaps, and that remains the way to do it today with ROS. That approach works, but I’ll be the first Continue Reading

The Role of WebRTC in Low-Latency Media Streaming

August 15, 2017 by Tsahi Levent-Levi Adobe recently wrote a touching obituary to Flash, announcing 2020 as the date of passing. While we’ve all known the end was near, having a date has set us free to look seriously at other options. One of the major advantages of using Flash Continue Reading

CISO Customer Panel – Accelerate 2017

Quite simply, this copycat group of cyber criminals had not actually carried out Continue Reading

The revenge of the listening sockets

Back in November we wrote a blog post about one latency spike. Today I’d like to share a continuation of that story. As it turns out, the misconfigured rmem setting wasn’t the only source of added latency. It looked like Mr Wolf hadn’t finished his job.

A Deep Dive Into DNS Packet Sizes: Why Smaller Packet Sizes Keep The Internet Safe

The attackers spoof their IP address so that the DNS answers are sent to the server Continue Reading
