From Isaac Sukin Command-line tip: replace a word in all files in a directory:
grep -lr --exclude-dir=".git" -e "oldword" . | xargs sed -i '' -e 's/oldword/newword/g'

Had the problem, that the VM didn’t start. (After reinstalling).
NtCreateFile(\Device\VBoxDrvStub) failed: 0xc0000034 STATUS_OBJECT_NAME_NOT_FOUNDSolved by reinstalling C:\Program Files\Oracle\VirtualBox\drivers\vboxdrv\VBoxDrv.inf (right click, install). And reboot afterwards.
Got myself a DX6.
Here is my best setting guess for the Blade Inductrix FPV:
I had problems with binding my new Blade Industrie FPV Pro to my Spektrum DX6i. Looked like it bonded, but nothing happened. This helped my out: link to forum.
So what to do:
You have to adjust (all) the travel to max (here 125%). Note: Use the sticks to switch between high and low. The other thing is to arm the motors: Switch flaps on and off after 2 seconds.
Hope this helps

Be warned, the Raspberry Pi with wlan is a slow nas. But I wanted to build one and there are no full instructions for it. So here are the steps to follow.
I used this instruction, but some things are missing and so I put everything down in short form:
Download the OMV Image here.
Use Etcher to flash it on SD card.
Insert card into raspberry, connect network cable. Wait (!) not only wait for the first time login, wait.. Raspberry upgrades in the background. Just do nothing(!) and wait more. About 10 to 40 min till the raspberry reboots again!
Now, login for the first time as root. Change Password.
Change Keyboard Layout if you don’t use english one:
dpkg-reconfigure keyboard-configurationcheck if your Wifi works:
ifconfig -aDo you see your wlan? If not, start at top.
Add your wifi with:
nmtui-connectagain:
ifconfig -aNow it could be a good idea to tell the router to fix the ip addresses.
sudo shutdown now
remove power
connect USB-Sticks, Harddisks, whatever. Be aware to use HD (also the 2,5) with their own Power(!).
Repower your raspberry.
And now first time to go to the OMV Web Interface.
Point your browser to one of the ip addresses.
Login admin/openmediavault
“System”
Change Password and Hostname in “System”
“Storage”
Format (Physical disks) then add Disk (file systems) in “Storage”
Select and Mount your Disk (file systems).
“Access Right Management”
Add a user in “Access Right Management”.
Add folder(s) in “Access Right Management”.
In “shared folders” mark folder and “give privileges” to your user.
“Services”
“Settings” -> Enable in “SMB/CIFS”
“Shares” -> add your folder
OK, now it’s the time to test your new nas. Go to your PC or Mac (smb://…your..ip…) and give it a try.

My Synology photo station seemed messed up. The indexing of photos never found an end, so it looked for me. This helped:
cd /var/spool/
sudo synoservicectl –stop synoindexd
sudo rm syno_indexing* — (delete all indexing files under /var/spool/)
sudo synoservicectl –start synoindexd
Mein iMac Retina 27” 2014 mit AMD Radeon R9 M295X 4096 MB fing plötzlich an, speziell bei Spielen, den Monitor auszuschalten. Also machte ich mich daran die Ursache, bzw. eine Lösung zu suchen.
Der Fehler scheint nichts mit der CPU Auslastung zu tun zu haben. Um aber genauer einzugrenzen installierte ich das Tool: https://bjango.com/mac/istatmenus/. Was ich herausfand, dass es ziemlich sicher mit der GPU Temperatur zu tun hat. Sobald die GPU Die Temperatur über 100 °C geht, schaltet der Monitor, bzw, eher die Grafikkarte, ab. Neben dem Einsatz von Staubsauger und Druckluftspray installierte ich folgendes Tool: TG Pro. Mit TG Pro kann man manuell oder auch eingestellt den Ventialtor steuern. Es sieht so aus, als ob der Ventilator nur über die CPU Temperatur gesteuert wird. So habe ich in TG Pro eingestellt, dass der Ventilator startet wenn die GPU Temperatur sich erhöht. Und siehe da: Seitdem geht es wieder. Bingo!

As my iMac Retina 27” 2014 with AMD Radeon R9 M295X 4096 MB startet to suddenly switch off the screen, especially while playing a full screen game, I started to look for the cause and a solution.
Thinking it might has to do with temperature I started to research. The black out doesn’t seems to have to do with cpu %. To search further I installed https://bjango.com/mac/istatmenus/ and found out, that the screen turns off when the GPU Die temperatur climbs around 100 °C. So what to do against that? Next was to install TG Pro an App you can use to manually (or automatically) turn on the fan.
And: Bingo! As I started to start the fan and cool down the GPU Die, the iMac stopped shutting down the Screen.
