openSUSE 11.4: How to sync Google Calendar and Contact with Kontact using Akonadi

joon — Thu, 02 Jun 2011 00:04:20 +0000

The following post: setting-up-google-calendar-with-kontact-or-korganiser-using-akonadi has very nice instruction with screenshots. Only package name and proxy settings are different in openSUSE.

Install akonadi-googledata (link to software search page)

Open up Akonadi Configuration, and click on Add… if you don’t see Akonadi Google Calendar Resourse, then you have to restart akonadiserver.

If you see that, then open korganizer and (this is pretty much copied from the above post)

Right Click on Calendars and click on Add Calendar …
Select Akonadi
Click on Manage Calendar Sources
Click add
Select Akonadi Google Calendar Resource
Enter your email and password and select ok

If akondadi google account shows “invalid password” right after you inputted the id and password, then go to Personal Settings – Network Settings – Proxy and check Connect to the Internet directly. Then the login should work.

After this, adding a new address book with Akonadi Google Contacts Resourse is straightforward.

KDE 4.6.3: workaround for Plasma panels don’t resize to fit screen height or width

joon — Sat, 21 May 2011 20:30:05 +0000

This is a workaround for Bug 265051:Plasma panels don’t resize to fit screen height or width … , and it is just Karsten’s workaround. I put it here for the record.

This happens in KDE 4.6.3 (possibly in other versions as well)

For this you need xdotool. It is in openSUSE:11.4:Contrib/standard repo for openSUSE 11.4.
1-Click Install

You need to make following two files:
panel.js

1	panelById(panelIds[0]).length = screenGeometry(0).width;

resize-kde-panel.sh

1
2
3
4
5

#!/bin/bash
qdbus org.kde.plasma-desktop /MainApplication loadScriptInInteractiveConsole
/home/......./panel.js
xdotool key ctrl+e
xdotool key alt+F4

You need to modify the path to “panel.js” file in the second line.

Now make resize-kde-panel.sh executable:

1	chmod +x resize-kde-panel.sh

Then whenever the panel needs resizing (potentially after connecting/disconnecting external monitor), just run that shell and it will resize itself.
You can make an application of this shell and run it in GUI mode as well.

openSUSE 11.4: Installation of IPython 0.11.dev

joon — Thu, 12 May 2011 22:48:15 +0000

Successful with openSUSE 11.4 x64 and IPython 0.11.dev

1. download

git clone git://github.com/ipython/ipython.git

2. dependencies

libzmq0
pyzmq

IPython 0.11.dev needs newer version of pyzmq than the one in the openSUSE repos.
You can install it with easy_install:

sudo easy_install pyzmq

If it fails because of libzmq0 version, then force the pyzmq version to be 2.0.10.1:

sudo easy_install pyzmq==2.0.10.1

3. compile & Install

sudo python setup.py install

Control volume with windows key + mouse wheel scroll

joon — Sun, 07 Feb 2010 17:37:48 +0000

If you are using AutoHotKey, it is very easy. Just add the following two lines to your script:

1 2	#WheelUp::Send, {Volume_Up 3} #WheelDown::Send, {Volume_Down 3}

Now windows key + mouse wheel scroll up will increase the volume, and windows key + mouse wheel scroll down will decrease it. Of course, you can always change the modifier. (for example, ^!WheelUp means Ctrl + Alt + wheel scroll up)

LaTeX word count

joon — Sat, 05 Dec 2009 02:24:59 +0000

Word count in a LaTeX document is somewhat tricky because you have to take out macros.

I just found LaTeX word count, which does this for you automatically. There is a Perl script you can download and use offline, but for infrequent use, the web-interface does the job beautifully. You can either choose a file or just copy & paste a LaTeX document.

It supports Unicode, and the author reports that Chinese and Japanese seems to work well.

TeXnicCenter 2.0 Alpha 1 Released

joon — Fri, 23 Oct 2009 20:42:27 +0000

TeXnicCenter 2.0 Alpha 1 has been released with much better looking editor window and unicode support.

In addition, I could start compiling with TexLive with minimal effort, and once I set my PDF viewer as SumatraPDF, forward search started working without any setting.

Since it is still Alpha, there are many glitches, but it looks very promising.

LaTeX handwritten symbol recognition – Detexify

Detexify is a LaTeX handwritten symbol recognition tool. You can just draw a symbol on the white box and Detexify will show you possible matched LaTeX symbols with their tags.

This can come in handy when you try to find out what is the tag for a certain symbol.

SlickEdit macro for passing line number and column number to user tools

joon — Wed, 29 Jul 2009 14:14:29 +0000

SlickEdit does not have built-in line number and column number argument to pass to User Tools. The following Slick-C macro will make the Sumatrafowardsearch work.

In SlickEdit, save this macro to any .e file, and load the macro from Macro -> Load Module menu.

Use it with %M current-line-number% and %M current-col-number% in the Tool definitions.
