Why #Twitter Didn’t Go Down
The first big point that is keeping the caches running is that they are ran as #Aurora jobs on #Mesos. Aurora finds servers for applications to run on, Mesos aggregates all the servers together so Aurora knows about them. Aurora will also keep applications running after they are started. If we say a #cache #cluster needs 100 servers, it will do its best to keep 100 running. If a server completely breaks for some reason, Mesos will detect this, remove the #server from its aggregated pool, Aurora will now be informed that there are only 99 caches running and then know it needs to find a new server from Aurora to run on. It will automatically find one and bring the total back to 100. No person needs to get involved.

From Pleiades to Hyades
Credit & Copyright : Rogelio Bernal AndreoExplanation: This cosmic vista stretches almost 20 degrees across the gentle constellation Taurus. It begins at the Pleiades and ends at the Hyades, two of the best known star clusters in planet Earth's sky. At left, the lovely Pleiades star cluster is about 400 light-years away. In a familiar celestial scene, the cluster stars shine through dusty clouds that scatter blue starlight. At right, the V-shaped Hyades cluster looks more spread out compared to the compact Pleiades and lies much closer, 150 light-years distant. Of course, the Hyades cluster stars seem anchored by bright Aldebaran, a red giant star with a yellowish appearance. But Aldebaran actually lies only 65 light-years away, by chance along the line of sight to the Hyades cluster. Faint dust clouds found near the edge of the Taurus Molecular Cloud are also evident throughout the remarkable 12 panel mosaic. The wide field of view includes the youthful star T Tauri and Hind's variable nebula about four degrees left of Aldebaran on the sky.
The Pleiades are 444.2 lightyears far from earth... that is 136.19 parsec. [+]
Another source tells that the cluster is between 434 and 446 light years from Earth. [+]

Moebius Strips by Tim Story and Contributors
- Curious Music is pleased to announce the launch of Tim Story's new audio installation Moebius Strips. Honoring Story’s collaborator and dear friend Dieter “Moebi” Moebius (Cluster, Harmonia, Brian Eno, Conny Plank), Moebius Strips is a multichannel audio installation for museums, festivals, galleries, and other public spaces. Working with Moebius’ widow Irene, Story has collected thousands of his sounds, noises, samples and loops, and reimagined/recomposed these in patterned ‘strips’ which, out of the context of their original settings, combine in new and ever-evolving layers on the installation’s soundstage. [...] including contributions from Geoff Barrow (Portishead, Beak), Sarah Davachi, Jean-Benoît Dunckel (Air), Eve Maret, Mark Mothersbaugh (Devo), Phew, Hans-Joachim Roedelius (Cluster, Harmonia), Michael Rother (Harmonia, NEU!) and Yuri Suzuki.

Un cluster de 51 cas de Covid-19 dans une maison de retraite de Toulouse
Cinquante et un résidents et personnels de la maison de retraite Pierre Ducis, dans le quartier de Casselardit à Toulouse, ont contracté le Covid 19, depuis le 21 août dernier. Les résidents, vaccinés pour la plupart, sont restés confinés dans leur chambre plusieurs semaines.
Pourquoi les contaminations ont explosé aux Pays-Bas, en France, en Espagne, et pas chez nous: à cause des nightclubs?
