TIME FOR BACKUPS AGAIN?
(Message 59154)
Posted 10 Dec 2018 by tullio
Post: When running UNIX Version 5 on an Onyx Computer in the years 1980-85 we made incremental backups every week because Winchester disks were very fragile. We made backups on tape with the "dump" and "restore" commands from Berkeley UNIX. All this is just history. Tullio |

Post: I wanted to take a MIT/Sloan course on Artificial intellgence but it costs 2600 dollars. A fairly equivalent course from Berkeley costs 357 dollars. All FutureLearn courses from Open University cost about 70 euros if you want to take the tests and receive a diploma, otherwise they are free. Tullio |

Post: About 21 hours on my Windows 10 PC with A10-6700 CPU which AMD says has four cores but the Windows Task Manager says it has 2 cores and 4 logical processors, so it runs only 2 BOINC tasks at the same time, plus a GPU task, either Einstein@home or SETI@home.Speedup of GPU tasks is impressive.

Post: My Windows 10 PC just rebooted after an update without any warning message. But I had only SETI@home and vLHC@home tasks on it, so no damage was done. I am running CPDN tasks only on my old Linux box, a SUN workstation of 2008 vintage, when they are available. Now it is running Einstein@home, both CPU and GPU tasks. I have installed on it a ATI/AMD HD 7770 GPU board and it works fine. The Windows 10 PC has a nVidia GTX 750 OC and it runs SETI@home GPU tasks. Tullio |

Post: 1 PNW task crashed on my Linux box after 433.35052 hours when at 99% but gave me 13k credits. I had to reboot the SUN WS with Opteron 1210, 8 GB RAM, SuSE Leap 42.1 64 bit when it was running also SETI Beta GPU tasks on a AMD/ATI HD 7770 GPU board. Maybe one of them crashed and the CPDN task did not survive the reboot. Tullio |
