All episodes of Joe Rogan Experience podcast are nearly three hours long, so I usually just watch the highlights. But this chat with Edward Snowden was well worth the full length watch.
Edward Snowden is one of the brightest and bravest people of our generation, and his story is fascinating. I think that this lengthy podcast episode provided a good channel for him to tell it. It’s not a tweet or a blog post, and it’s not strictly framed corporate media.
I also think that Joe Rogan is one of the finest interviewers today. In this episode, he shows that very well, but remaining silent for almost all duration of the show, with an occasional steer of the conversation.
I wish there were more content like this online.
Oh, and just for the record, “Permanent Record” is the book that Edward Snowden has written and is heavily referencing in this talk. I’ll definitely be buying a copy.
Currently, there are 3796 devices monitored by the Zabbix server, which in turn houses the MySQL database and the web front-end. This server is operated virtually with 8 CPU’s and 32GB RAM supported by SAS storage system. 105818 items are queried by the Zabbix server from those devices, where 23820 triggers detect whether certain items deviate from their target state. This results in 298.48 NVPS with an average of approx. 7 people (actively) using the system concurrently. General overview: * Each device inside a tram/subway is treated as a host and is monitored for availability. * Each tram/subway is managed as a host group. * Host groups are nested and organized by the tram/subway lines (using the host group nesting feature introduced in Zabbix 3.2). * All devices depend on the connectivity of the MRCU (Mobile Radio Control Unit in subways) or LTE router (LTE G4 Connectivity in trams) * Maps are automatically created for each tram/subway (using the Zabbix API). * Maps use sub-maps to link to a specific tram/subway view.
There’s also a video from the Zabbix conference, presenting the case study.
National Oceanic and Atmospheric Administration (NOAA) has this excellent visualization of the earthquakes recorded between January 1, 1901 and Decemeber 31, 2000. Each earthquake is shown as a circle, where the size indicates the strength and the color indicates the depth. Interesting, how most of these make up lines, showing the tectonic plate borders.
