Ubuntu — ZoneMinder Socket_sendto or no live streaming

Jovan Stosic August 1, 2018

After you have setup your camera make sure you can view Monitor streams, if not check some of the common causes:

  • Check Apache cgi module is enabled.

  • Check Apache /etc/apache2/conf-enabled/zoneminder.conf ScriptAlias matches PATH_ZMS.

    ScriptAlias /zm/cgi-bin /usr/lib/zoneminder/cgi-bin

    From console go to Options->Path and make sure PATH_ZMS is set to /zm/cgi-bin/nph-zms.

Democritus

Jovan Stosic August 1, 2018

Democritus (/dɪˈmɒkrɪtəs/; Greek: Δημόκριτος, Dēmókritos, meaning “chosen of the people”; c.460 — c.370 BC) was an Ancient Greek pre-Socratic philosopher primarily remembered today for his formulation of an atomic theory of the universe.

Democritus was born in Abdera, Thrace, around 460 BC, although there are disagreements about the exact year. His exact contributions are difficult to disentangle from those of his mentor Leucippus, as they are often mentioned together in texts. Their speculation on atoms, taken from Leucippus, bears a passing and partial resemblance to the 19th-century understanding of atomic structure that has led some to regard Democritus as more of a scientist than other Greek philosophers; however, their ideas rested on very different bases. Largely ignored in ancient Athens, Democritus is said to have been disliked so much by Plato that the latter wished all of his books burned. He was nevertheless well known to his fellow northern-born philosopher Aristotle. Many consider Democritus to be the “father of modern science”. None of his writings have survived; only fragments are known from his vast body of work.

Owncloud is slow when a federation server is down

Jovan Stosic July 31, 2018

I had two ownclouds 9.1.8. I shutdown the one owncloud  server, resulting in terible reduction in speed of the other owncloud server. Deleting from the web interface was not possible, too.

Deleting the rows in the database of oc_share_external worked, external shares are now gone and the performance of the active owncloud normalized.
