> I read that defector provided soviet jets at one point had tiny weeny valves, which were not indications of how backward their electrical engineering was: they were capable of being rad-hardened more than the IC's of the time. I'm not sure this is true.
Viktor Belenko's defection to Japan w/ a MiG-25 is a fascinating story unto itself. But, yes, the MiG-25 had vacuum tubes and other design elements that seemed like anachronisms @ first glance.
> The use of vacuum tubes also made the aircraft's systems resistant to an electromagnetic pulse, for example after a nuclear blast. They were also presumably used to provide radiation hardening for the avionics.
Whenever Vacuum tubes and Soviet Era aircraft are brought up it's stated they used vacuum tubes because they lacked the capabilities to make semiconductors. I am sure it helped with rad-hardening but it was not the reason they chose the tech.
This is my setup on all my raspberrypis. I have not be been able to figure out how to monitor a cluster though. I saw that grafana free tier doesn’t allow a cluster of servers getting monitored. I have telegraf + influxdb + grafana installed on all my servers.
I have telegraf + influxdb + grafana-server installed on each of my Rpis giving me multiple dashboards. I want only one grafana-server dashboard where all the telegraf metrics could be seen.
Contemporary application: A Texas businessman convicted of plotting to violate the U.S. Neutrality Act in a failed 2014 bid to overthrow the government of Gambia and install himself as president of the tiny African nation was sentenced on Thursday to a year in prison.
Ah, that was back when AA and Alaska were much closer partners, before the Virgin acquisition... I was surprised when reading the article that Alaska was so helpful.
