A few days ago,one of the Davis Instruments’s Automatic Weather Stations that has the Dirección de Hidráulica of the Province of Entre Rios presented a problem receiving data from the sensors.
When we went to see what was happening, we noticed that the console showed a message that said “NOT LOCK PLL. PLEASE REBOOT”.
We didn’t found much information about it on internet, so we decided to update the console’s firmware, which didn’t do nothing. We decided to bring the console to our workplace to evaluate it and see if we could find a solution.
After a few days, when the console was without batteries or any power, we decided to turn it on, to our surprise, the console booted successfully, without displaying the message, and began to receive data from the sensors we have in our building.
Honestly, we could not find out what the problem was, nor what was the solution, but the console is running with no problems now.
I conclude that it may have been a parameter that remained (wrong) configured on the console, even while it was without batteries or power transformer, solar panel, etc., and it lost to be without power for a period of time considered.
My computers have a configuration to automatically mount some NTFS partitions when Fedora starts, in these partitions I share files between Windows and Fedora.
I recently upgraded to Windows 8, and after meeting him, I wanted to boot Fedora again, and gave me an error trying to mount the partition.
Here, I explain what is happening and how to solve it. Continue reading
I stored most of my files on my desktop computer, other files were saved on my notebook, it had less space, and others automatically synchronized with Dropbox, It ended when I change the notebook, and now, the new notebook has more space than the desktop computer, but storing everything in the notebook is dangerous and unsafe, so I just want to make the data in the 2 computers.
There are different alternatives for automatic synchronization (most of them are pay), in my case, I decided to use UNISON, a multiplatform application that allows the synchronization between two host, or also between two local directories.
Synchronize means “Make matching in time two or more movements or phenomena.”, therefore, that is exactly what Unison makes, the changes are propagated bidirectionally, it mean, files that are on the host “a” and are not in the host “b”, are copied, and vice versa; Also, it compares file dates to detect, obviously, which is more recent.
Unison, as mentioned above, allows synchronization between local directories, and between different hosts using SSH (Secure Shell), RSH (Remote Shell) and TCP (with socket). As SSH is the safest method, is the one I chose to operate , and we will use in this simple guide.
