Gimp and rule of thirds guides

Ever wanted to use rule of thirds guides in gimp?

Here is a simple guide that works just fine: http://registry.gimp.org/node/13536

Realtek gigabit usb ethernet card with usb hub

Just got this ethernet/hub combo and I was unable to make it work. I was getting the following error:

[ 265.335354] usb 1-1.1.3: Manufacturer: Realtek
[  265.335358] usb 1-1.1.3: SerialNumber: 00E14C3600C8
[  265.428826] usb 1-1.1.3: reset high-speed USB device number 19 using ehci-pci

[  267.197045] IPv6: ADDRCONF(NETDEV_UP): enx00e14c3600c8: link is not ready

and no connectivity.

After some digging, I discovered that my network card is a Realtek 0bda:8153, this card is supported by the driver r8152 that already existed in my system.

Some more digging brought this on surface: https://bugzilla.redhat.com/show_bug.cgi?id=1236679

In short it seems that tlp tries to save power for me by blocking my network card. The solution is to add the following

USB_BLACKLIST="0bda:8153" in /etc/default/tlp and reconnect the card. After that everything works as expected.

Typing the € symbol in a linux system

For infrequent users:

If you use English (US) keyboard layout and you don't want to change it, the the fastest way would be to use Ctrl+Shift+U key combination and then type 20ac followed by Space(or Enter) which will turn into €.


The Xorg solution:

In your keyboard layout settings choose Options -> Add currency signs to certain keys then choose the key you can use to activate that option by changing the option Key to choose 3rd level (or 4th depending on which level your currency symbol is. you can get the full keycodes by using xmodmap -pke in console)
For this you can choose use Win key, its useless in Linux anyway, so you might as well find some use for it.



The console solution:

---

xmodmap -e "keycode 13 = 4 EuroSign 4 EuroSign"
xmodmap -e "keycode 13 = 4 dollar 4 dollar"
xmodmap -pke > .xmodmap
xmodmap .xmodmap

Now if you want, for example, to change the $ sign (which you can type it using Shift+4 shortcut when you have an US English keyboard) with € sign, you can use the following command in terminal in terminal:
From now you can type € using Shift+4 shortcut.
To switch back to $ sign, use:
To get this change for every session, create a file called .xmodmap, with the following command:
Then, create a file called .xinitrc in your home directory, containing the following line/command:
In the same mode you can set any other key combination to type € symbol. Use xmodmap -pke command to see all keycodes and their map assignment.
