Sprint at CERN: it’s coming….

The sprint at CERN is already almost there.

I was quite afraid that our part (reorganizing the Techbase wiki) would not be doable because of the problem KDE had on all the wikis. Because of a severe spam attack [1], all edition rights were suspended until a better authentication was implemented.

It is now done! (kudos @neverendingo, @bcooksley, @Nikerabbit and all people who contributed to that)

What are we going to do there?

As already written in my previous post, this sprint is a WikiToLearn [2] sprint. Other projects, such as Plasma and the VDG Team were kindly invited to join. I’ll be part of the team working on tidying up the Techbase wiki [3].

This includes moving the KDE4-related documentation to an archive namespace, (re?)moving old drafts and duplicate documentation, checking that everything we leave in the main namespace is up-to-date. And certainly more.

What already began… What can you already do?

I’ve seen that @jucato already began to port some tutorials from KDE to KF5. He added some tasks that I regrouped here [4]. It’s not comprehensive but still a good start.

Begin to have ideas, create tasks in the project techbase on our Phabricator, and do whatever usefull I haven’t thought of!

Keep in mind…

KDE ev. is supporting this sprint: I know it is worth it and that this money is well spent… Let’s rock this!

Cheers and have fun!

Setting the wifi on the Raspberry Pi with a TL-WN725N v2 adaptor

Since the release of the Linux kernel 3.4, the driver RTL8188eu is provided by default, which wasn’t the case some times ago: the TL-WN725N v2 wifi dongle should be working out of the box.

Install what you need

# pacman -S wpa_supplicant
Yes, that’s it… Because netctl is already installed.

Configuration of the wifi

Prepare the WPA key

# wpa_passphrase your_essid 'passphrase'

Put the passphrase between simple quotes to escape special characters.

You should get someting like:

network={
  ssid="your_essid"
  #psk="passphrase"
  psk=64cf3ced850ecef39197bb7b7b301fc39437a6aa6c6a599d0534b16af578e04a
}

Copy the psk value.

Set up netctl

To now the name of the interfaces type:
# ip link show

Here I have lo (loopback interface), eth0 (ethernet), wlan0 (wifi).

In /etc/netctl/wlan0-your_essid

Description='description'
Interface=wlan0
Connection=wireless
Security=wpa
ESSID=your_essid
IP=dhcp
Key=\"64cf3ced850ecef39197bb7b7b301fc39437a6aa6c6a599d0534b16af578e04a

Note that the value of Key is \"[what you copied before]

Test it

# netctl start wlan0-your_essid

If it works it can be enabled at boot.
# netctl enable wlan0-your_essid

If it doesn’t work, you can try to see if the problem comes from the interface or not. Using wifi-menu can be helpful. It’s a dialog in the terminal that makes things easier and in an automatic way. However it seems to have troubles with special characters in the password.

Else follow the sources …
