So I've downloaded a KDZ of the latest European version for the LG G2 16GB here (when I wrote these lines it was D80220D ) and I've followed these instructions to install it on my phone.

I was trying to link a Progress database to an SQL Express server few days ago. The connection has first worked fine, but at one moment, I was not able to run any queries and finally got this error message : DataDirect ODBC Progress OpenEdge Wire Protocol driver Broker rejects connection In my case, this error was caused by too many active connections from the user I used to connect from ODBC. But all the applications were closed. So I've used the utility proshut to list all connected users and to kill the unreleased connections: list connected users : [path to proshut] proshut.bat [path to your db] .db -C list kill a specific user :  [path to proshut] proshut.bat [path to your db] .db -C disconnect [user number] #1 #2

Today I got an error while trying to delete a VirtualBox snapshot : "Failed to delete the snapshot XXXX of the virtual machine YYYY" (english) "Échec de la suppression de l'instantané XXXX de la machine virtuelle YYYY" (french) Hard disk 'XXXX.vdi' has more than one child hard disk (2). In the snapshot manager, there were only two snapshots linked to my virtual machine. I could delete the newest one, but I was not able to delete the oldest one/root snapshot. To resolve this issue, I went to the "File > Virtual Media Manager" menu, then the [Hard Disks] tab and I've expanded the tree under my virtual machine. I've deleted one snapshot that was not linked to any virtual machine, or snapshot. After what I was able to delete my oldest/root snapshot.

In the pink world of Ubuntu from where I come, things are easy, and PATH variable is fully set in each context. But in the dark world of OpenBSD, things aren't always obvious ;) If you decide to write a bash script intended to be used as a cron task, DO NOT forget to fully qualify path of non standard commands : e.g. zip or smbclient should be written as /usr/local/bin/zip and /usr/local/bin/smbclient . Hope it could save time for others...

For example uptime seems completly broken and ls doesn't use color anymore. I've fixed this issue with the following commands: ln -sf /bin/ls /opt/bin/ls ln -sf /usr/bin/uptime /opt/bin/uptime

As I m completly unaware of the openssl use, I only write here some observations I made : If after the command : openssl ca -out cert.pem -infiles req.pem you got the following error message : failed to update database TXT_DB error number 2 This is probably because you have generated your own signing certificate with the same Common Name (CN) information that the CA certificate that you've generated before. Simply input a different Common Name each time you are asked should do the trick. Credit : 1
