Solar - a theme for Python Sphinx

Sep 04, 12

Solar is a theme for Python Sphinx.

preview | download
Made the switch to Vim - at last!

Mar 29, 12
Eclipse was my IDE of choice. I liked the Python support with Pydev extension, Git integration, multiple project management and Task/Todo support among other things. I have written about some of these before.

What I didn’t like was the high memory usage. Tried a number of things - updating Eclipse and JDK, making sure 64-bit Java is used for the VM, disabling or removing features/plugins not used and closing unused projects. It didn’t help much - ~300MB RAM with a single project opened in workspace!

I have been using Vi/Vim for a long time (~10 years) but only for simple tasks. I even got a book but the learning process was slow. On second thought, I realized it will be quicker if I noted down the features I wanted and focus only on them. So, I came up with this list
- Python, Pylint integration
- Git integration
- Diff
- Debugging python code
- Execute shell commands
- Find and replace
- File explorer
- Working with multiple files
- Project management
- Help and autocomplete
- Tasks integration
I’ve got most of this setup thanks to some really good blog posts, wiki articles and stackoverflow posts [see Links below]. Here is my vimrc. I use solarized for the color scheme and Inconsolata font at 10pt.

Some tips

Find and highlight occurrences of a word

Press * while cursor is on the word.

To remove highlight, use
```
:set nohl
```
Close a file

Also known as delete a buffer.
```
:bd
```
Print margin at column 80

This is useful if you want to restrict the number of characters per line.
```
:set cc=80
```
For more information, check “Right margin in Vim”

Display line number
```
:set number
```
Diff of 2 files
```
:vert diffsplit second_filename
```
This did not work on the windows version of vim 7.3. Remove or comment out
```
set diffexper
```
in vimrc. You will then need to install diff. I used diff.exe that came with Git. For more information check Running diff.

qt-devel on SLES 10 SP1

Mar 28, 12
Problems

No Qt development (qt-devel) RPM in the SLES 10 SP1 DVD.

The devel files were part of the SDK. Could not download SLES 10 SP1 SDK from Novell (No longer available). The official installer did not work.
```
./Qt_SDK_Lin64_offline_v1_2_en.run: 
/usr/lib64/libstdc++.so.6:version `GLIBCXX_3.4.9' not 
found (required by ./Qt_SDK_Lin64_offline_v1_2_en.run)
```
Cannot upgrade libstdc++ at the moment!.

How I got it installed

Downloaded the latest available SDKs for SLES 10 from Novell http://download.novell.com/Download?buildid=JETn_0Tw_XM~

Extracted qt-4.3.4-0.7.1.src.rpm from the 2nd DVD iso

Built RPM from the source RPM
```
rpmbuild -bb qt.spec
```
This stopped with error: Failed build dependencies:
```
cups-devel is needed by qt-4.3.4-0.7.1.x86_64
libjpeg-devel is needed by qt-4.3.4-0.7.1.x86_64

libtiff-devel is needed by qt-4.3.4-0.7.1.x86_64
dbus-1-devel is needed by qt-4.3.4-0.7.1.x86_64
```
Installed all the above packages using zypper

Compile was successful but these rpmbuild errors occured
- suse_update_desktop_file
  
  Due to a bug in /usr/lib/rpm/suse_macros https://bugzilla.novell.com/show_bug.cgi?id=166170.
- unpackaged files found
  
  Updated spec file to include them in sql package.
Removed existing Qt installation and installed new RPMS
```

2011 in review

Dec 31, 11

The WordPress.com stats helper monkeys prepared a 2011 annual report for this blog.

Here’s an excerpt:

The concert hall at the Syndey Opera House holds 2,700 people. This blog was viewed about 31,000 times in 2011. If it were a concert at Sydney Opera House, it would take about 11 sold-out performances for that many people to see it.

PostgreSQL notes

Nov 01, 11

Some things I’ve learnt recently.

Simple boolean function to check if a column exists

SELECT EXISTS(SELECT 1 FROM information_schema.columns WHERE table_name = tabname AND column_name = col1)

Identify duplicate values in columns

SELECT key FROM tabname GROUP BY key HAVING (COUNT(key) > 1)

col1 is an integer but I wanted it formatted as text in my python script

SELECT CAST(col1 AS TEXT) FROM tabname

Beginning PyQt (tutorial, PyCon Ireland 2011) - slides and code

Oct 10, 11
This is a tutorial I delivered at PyCon Ireland 2011.

A quick introduction to developing a GUI to a command line program using PyQt. I used the sphinx-build command from Sphinx documentation project as an example.

The basic command for generating HTML documentation from source is
```
sphinx-build sourcedir outdir
```
A GUI (dialog) was designed using Qt Designer to replicate the functionality of the command above. This was then converted to Python code and then a main application was written to make use of the dialog.

Slides for the talk: slides.pdf

Code repository: https://github.com/vkvn/sphinx-build-qt/

You can clone the repo using
```
git clone git://github.com/vkvn/sphinx-build-qt.git
```
and checkout like this
1 2
cd sphinx-build-qt git checkout pycon
This code works unaltered on Windows too. Thanks to Qt! You would need to have the C:\Python2*\Scripts in your PATH or wherever you’ve got sphinx-build installed.

3 new themes for Python Sphinx

Jun 26, 11
Just created a repository for the Sphinx themes I have been creating for various documentation projects. These themes were created by modifying base themes included with Sphinx. Here are some screenshots.

Agni (means Fire)

Jal (means Water)

VLinux-theme (used for the VLinux project)

Download
- Agni - agni-1.0.zip
- Jal - jal-1.0.zip
- VLinux-theme - vlinux-theme-1.0.zip
You can clone or fork the github repo.

How to use
1. Download the zip file of the theme you want to use and uncompress the archive.
2. Modify conf.py of an existing Sphinx project or create a new Sphinx project using sphinx-quickstart.
3. Change the html_theme parameter to match the theme name (agni, jal or vlinux-theme).
4. Change the html_theme_path to location of the downloaded theme.
Now running Android 2.3/CM7 on the Milestone (with some Honeycomb goodness!)

Mar 10, 11

CyanogenMod 7 (Android 2.3/Gingerbread) port for Milestone is now available (RC4, but quite stable) - http://android.doshaska.net/cm7

Instructions to update are similar to what I have posted before except there is no need to install OpenRecovery and all three data wipe options should be used including Factory reset.

NOTE: This is going to wipe out all your data. So, backup first!

Also, latest version of Google apps for CM7 needs to be installed.

Optional

Honeycomb theme for CM7. Download here.

Honeycomb live wallpaper from Android Market

Screenshots

Power control, Google search, Beautiful Widgets, Google Reader and LauncherPro

Analog Clock from the Honeycomb theme

Also includes Music widget.

New icons from Honeycomb theme

Python Sphinx - include sections from other documents

Feb 10, 11

I was trying to do this today and came across couple of different ways of including content from other documents. My first attempt was to use .. literalinclude:: but that is only good for including code or text. What I wanted was to include sections from other documents into the current document so that any changes made in them will also be reflected in the document where it was included. This can be done using the .. include:: ReST directive.

Lets take this document usage.rst as an example:

Usage
=====
This is a document about usage of the program

Command
-------
How to use the program

`python my_program.py`

Doesn't change after adding more lines

Setting paths
-------------
Either set the ``PATH`` variable of set os.environ['PATH']
in the beginning of the script

Lets say you want to include the Command section. Mark this section by adding markers like this. In this case begin-command and end-command is used. This is not really necessary and any string could be used as a marker but I feel this gives better control as to what is included.

Usage
=====
This is a document about usage of the program

.. begin-command

Command
-------
How to use the program

`python my_program.py`

Doesn't change after adding more lines

.. end-command

Setting paths
-------------
Either set the ``PATH`` variable of set os.environ['PATH'] in the
beginning of the script

Note Spacing is essential. The .. at the beginning of a line makes it a comment. It will not be included in the final document

To include this section in a different document, add this

.. include:: /concept/usage.rst
   :start-after: begin-command
   :end-before: end-command

Note The / in the beginning of the path refers to the top level i.e., the ‘source’ directory. If the file is in the same directory, just filename is sufficient

Arista transcoder does a very good job of converting videos (Linux)

Feb 06, 11
Just came to know about Arista, a transcoder for Linux from the Linux Action Show. It was in the pacman repo for openSUSE. Used a 170mb flash video and converted it using the Milestone (Droid/Milestone) preset. The resulting MP4 video was around 143mb. Arista can also generate videos in a number of formats including WebM.

Presets available for Android phones
- Droid/Milestone
- Droid X
- Galaxy Spica/GT-15700/Galaxy Lite
- Samsung Galaxy S
- G1/Dream
- Nexus One/Desire

Compile Boxee from source code (openSUSE 11.3)

Jan 31, 11

This is a copy of the post I made in the forums about compiling Boxee from source code under openSUSE 11.3.

I had the required libraries installed before. Most of them can be found in the openSUSE oss or the Packman repositories.

Download

Download the latest sources boxee-sources-0.9.23.15885.tar.bz2

Extract the archive

cd Downloads
tar jxvf boxee-sources-0.9.23.15885.tar.bz2

Compile

cd boxee-sources-0.9.23.15885
./bootstrap
./configure --enable-pulse

I only enabled this, you can get all the options using ./configure --help This resulted in the first error message

configure:11950: error: in `/home/vimal/Downloads/boxee-sources-0.9.23.15885':
configure:11954: error: cannot compute sizeof (size_t)
See `config.log' for more details.

config.log had this

configure:11946: gcc -o conftest    conftest.c  -lrt -ltiff -ljasper -lresolv -ldl -lz -llzo2 -lpthread -ljpeg -lbz2  -lGLU -lGLEW -lGL  -lmad -lm   -lfontconfig   -lfribidi   -lsqlite3    -lpng12   -lpcre   -lfreetype   -logg   -lvorbis   /usr/lib/libmysqlclient.so.16 /usr/lib/libcdio.a  -lsamplerate    -lasound   -lenca -lm   -lXt -lX11 -lSM -lICE   -lXtst   -lXmu -lXt  -lX11 -lSM -lICE   -lXinerama   -lcurl   -ldbus-1 -lpthread -lrt    -lhal-storage -lhal -ldbus-1 -lpthread -lrt   -lSDL -lpthread   -lhal  -ldbus-1 -lpthread -lrt   >&5
/usr/lib/gcc/i586-suse-linux/4.5/../../../../i586-suse-linux/bin/ld: cannot find -lsamplerate
collect2: ld returned 1 exit status

libsamplerate and libsamplerate-devel were installed but for some reason pkg-config was not finding it. I uninstalled both of them after ignoring the dependencies (not good, I know but wanted to get it to work. besides this is my test machine…), downloaded the sources for libsamplerate from http://www.mega-nerd.com/SRC/download.html. The latest version is 0.1.7

Compiled and installed libsamplerate

cd Downloads
tar zxvf libsamplerate-0.1.7.tar.gz
cd libsamplerate-0.1.7
./configure --prefix=/usr
make
make install

Back to the boxee-sources-0.9.23.15885 directory and running configure

./configure --enable-pulse

Worked fine this time. I then did a

make -j2

There were two undefined references during make. One was related to TP*Policy and the second ones were referring to mms* functions.

Using information from forums, added the following to end of LIBS configuration in the Makefile

xbmc/ThreadPolicy.o -lmms

I’ve attached my Makefile with this post

After this, I had to run

make -j2

twice to build the Boxee executable. This was always the case. I have no idea why this is.

Run boxee using

./Boxee

or create a symlink to ~/bin

I have tested few apps like Youtube, Revision3, Cnet and Earth-Touch. They all work fine.

PortableApps updater (beta) - what Windows update should have been...

Jan 27, 11
PortableApps makes it easy to carry programs on a USB stick. It can also be installed on a hard disk. With the latest beta, it is possible to keep all applications updated automatically.
```
Launcher in the system tray --> Manage Apps --> Check For Updates
```
This is a really nice as it eliminates the need to download and update individual programs, as is currently the case with Windows.

Jan 27, 11
Install Gmote on the computer. In Linux, extract the archive and run
```
./GmoteServer.sh
```
Install Gmote 2.0 from the Android market.

The phone and computer should be on the same network.

Open Gmote on the phone, bring up the menu and tap Find server. Browse to play audio/video file and choose the option to play it on the phone. That’s it!

Disable connections to a PostgreSQL database temporarily

Jan 27, 11
Today, I had to disable access to some PostgreSQL databases temporarily. This can easily be done using pgAdmin. Under database properties, set Connection Limit to 0 from the default(-1). The corresponding SQL statement is
1
ALTER DATABASE "dbname" WITH CONNECTION LIMIT = 0;
When you are ready to allow connections, change this back to -1.

Jan 17, 11

Bioinformatist.org is a wiki providing instructions for installation of software used in Bioinformatics. It requires a new logo. Here is something I came up with. Suggestions and comments welcome.

Update

Two designs based on feedback

Decided to go with the second one.

Used icons from the wonderful Faenza theme by tiheum as a base.
CyanogenMod on the Milestone

Jan 02, 11
Update

I have now upgraded to CyanogenMod 7 (based on Android 2.3). Please check this post for details. Steps are similar to what is mentioned here.

This post is about how I got CyanogenMod installed and running on the Motorola Milestone. More information on CyanogenMod can be found here or here. The Milestone port of CyanogenMod was made by nadlabak

Read! Read! Read!

Proceeding further means you understand what you are doing. I am not responsible for any damages that might occur! This might also void your warranty. This worked for me.

Backup all important data

Data on SD card like photos, music will not be affected. SMS messages, call logs and music playlists will be removed. If you have lots of messages, you could try one of the SMS Backup apps from the market, which will save all messages to GMail or SD card. It would be wise to check on a per-app basis to see if data is stored locally or in the cloud.

Flash vulnerable recovery.

Without this, remaining steps will not work! Please see this link for instructions.

Take up one idea. Make that one idea your life - think of it, dream of it, live on idea. Let the brain, muscles, nerves, every part of your body, be full of that idea, and just leave every other idea alone. This is the way to success.
