Synchronizing Notes in XFCE with Dropbox/Ubuntu One


If you have a lot of notes like me, you would probably want instant access to them. While Evernote is a good application to get the same results, I find the everpad interface on ubuntu rather annoying. And I prefer to use the native app in XFCE for notes - conveniently called "Notes". This app has the advantages of being lightweight, fast and easily accessible - but only on my personal laptop. What if I need access to some of this information when I am at work? The answer is simple - your favourite online sync service.

The good thing about Notes is that it saves everything in the plain text format - no hassles there. You could just take these files with you and use any reader to open them. Even on your mobile device! All you need to do is sync them using Ubuntu One or Dropbox (or any other sync service of your choice). The folder to sync is :
~/.local/share/notes
Sharing this with Ubuntu One is easy. Just fire up Ubuntu One, and add the above folder and everything should be smooth.

For Dropbox, however, there is no straightforward way to accomplish this. But with a little trick, this should be as easy typing a line out on the terminal - literally. Open up your terminal and navigate to the Dropbox folder and type:
user@pc:~/Dropbox$ ln -s ~/.local/share/notes/
This command creates a symbolic link in your Dropbox folder that points to the location of your locally stored notes. Presto! Now your notes are synced across all of your devices with Dropbox. It also becomes easier to share specific notes with certain people through Dropbox. If I wish to share the travel notes I have made for the upcoming trip with my girlfriend, I could just share the ~/Dropbox/notes/Travel folder with her.

My Conky Configuration (and how to set it up)

I have been a huge fan of Conky for some time now. However, I have always found tinkering with the configuration files and scripts too intimidating. So, I had been stuck on using the Clock Rings configuration.


Although it looks quite elegant, I was bored of it because I would rather use the space on my desktop for displaying information I care about. So, I went to work and tried my hand at it again. Making use of the resources I mentioned in my previous post, I finally tweaked the configuration to fit into my scheme of things. The end result looks something like this:

Because I put a lot of effort into putting things into place, I think it is worth sharing it. Let me take this moment to point out that this configuration may not be the best for you. Heck, some people may also find it an eyesore. But the beauty of linux lies in that fact that it is customizable. The purpose is not to have a one-configuration-fits-all solution. Rather, it is to have a free knowledge base of ideas so that you can build your own setup that suits your purpose.

OK. Now that I have made my point, let's get back to business. So, what is required?

To make this configuration work as is, the following elements are needed:

1. The Conky Configuration File
2. Scripts for Weather, Google Calendar, External IP
3. Fonts

Let's have a look at each of them one by one:

Scripts


Weather
The weather scripts are supposed to download the weather-related information from sites such as AccuWeather/WUnderground and extract useful information out of it. This information is then stored in text format to be utilized by the .conkyrc file. My configuration makes use of Teo's 1d2 accuweather script (acc_int_cwfont). While it is possible to use some of his other scripts, it will also require a lot of changes in the conky configuration file.

Google Calendar Template (.conkyGoogleCalendartemplate)
This script is just a template to present the appointment information in a specific way. I have written it to display the Event title, starting time and location. You could change it to display other variables like end time, etc.
${font Droid Sans:pixelsize=16}[title]
${font Droid Sans:pixelsize=14}[starttime]
${font Droid Sans:pixelsize=14}[location]

Script to find External IP (ip.sh)
This scripts uses the wget command to get your external IP from the dyndns website. You could a different website, with a little change in the latter half of the script if you know what the output looks like.
#!/bin/bash
# Script to Find External IP

wget http://checkip.dyndns.org/ -q -O - |
grep -Eo '\<[[:digit:]]{1,3}(\.[[:digit:]]{1,3}){3}\>'  

 Additional Fonts

The fonts I have used can be divided on the basis of Text and Symbols. The text fonts are easily replaced by a substitute of your choice. The symbols, however, cannot be. They are meant to display specific information like weather (Sunny/Cloudy/Rain) or Email.

Text Fonts
ZegoeLight-U, Droid Sans, Droid Sans Mono, Trebuchet MS

Symbol Fonts
Conkyweather (Weather Section), conkysymbols (Unread Emails Section), Buttons and Switches JL (Conky Clementine Section)

That pretty much concludes the configuration. With all of these elements, you can easily recreate the above configuration. :)

PS: Note that the paths in the Weather script(s)/configuration file need to be reconfigured for a different setup.

Conky Configuration Guide


There have been tremendously detailed guides on configuring conky all over the internet. However, so much information can be confusing at times. And this universe of information can be especially intimidating for the people new to conky/linux. I felt the need to make a collection of useful and regularly updated resources to make the daunting task of configuring your conky a little easier.

From knowing nothing about conky, I have made use of some of these online resources to make my conky look like this:


Let's take it step-by-step.

1. Installation


The installation for various distros are well documented on the official conky webpage.

Debian/Ubuntu

At a terminal:
$ sudo apt-get install conky

Gentoo

Have no fear, Conky is in portage. You can install it with:
# emerge app-admin/conky
 
or, using Paludis:
# paludis -i app-admin/conky

Arch

Conky is available in pacman:
# pacman -S conky 

 FreeBSD

Conky is avaible in FreeBSD ports, check FreshPorts for details.

Foresight

For Foresight Linux or any other rPath-based distro:
# conary update conky=cookingwithroids.rpath.org@cwr:all

Compiling from source

You'll need the X11 development libraries, version 6.8.2 or later. package name is probably libx11-dev (on Debian/Ubuntu), as well as the development libraries for any additional features.

$ ./configure --prefix=/usr --enable-x11 --enable-mpd # see --help for a full listing of options

$ make 

# make install
The last step is optional, if you don't do this, the conky executable will be in src/.

2. Configuration


So you just installed a shiny new conky on your computer. But nothing seems to work. Why is that so? This is because conky needs a configuration file to tell it what to display. This is usually named as .conkyrc and it contains instructions about what information to display on your desktop and how. Understanding the configuration file may seem difficult at first but you get the hang of it in a couple of hours even if you have never done any programming before.

A good resource to tweak the configuration file according to your needs has been written by VinDSL on ubuntuforums. The link to the guide is:

VinDSL's Conky Configuration Guide


3. Additional Dependencies & Fonts


Most configurations make use of additional scripts/plugins/fonts. Examples of these include certain weather scripts, email checking scripts or scripts that fetch the current track information from your music player.

These scripts have to be downloaded separately, and their paths configured in the conky configuration files that make use of them. Sometimes, the scripts themselves need additional editing - but this is usually very simple and often involves just replacing certain fields like your email id & password or the link to your local weather conditions.

4. Weather


Okay, why do I need to mention weather separately? Because configuring this part may be trickier than others. It used to be easy before weather.com made drastic changes to their website. Most scripts made use of weather.com until almost an year back, when the website made it mandatory to register to fetch weather updates.

One of the best resources I have come across for this is by Teo. The complete thread is at the following link:

Teo's weather scripts using Accuweather/WUnderground/NWS/Weather.com

5. Additional Information/References


If you are already familiar with a little programming and do not wish to go through the lengthy guides mentioned above the Arch Linux Wiki on conky is a good place to start. It details a lot of things from fetching RSS feeds to configuring GMail in conky.

Arch Linux Wiki

Another useful and concise option is the conky variable list at the official webpage on sourceforge. This list is presented in the form of a table, with a short description of how each command works. A little familiarity with conky may be required before you jump to this one.

Conky variables list on Sourceforge

Happy Conky-ing!

16 Awesome Conky Configurations

I have been a huge fan of Conky. For those of you who have no idea about it, here is what the "Setting up Conky" webpage has to say about it:
Conky is a system monitor for X originally based on the torsmo code. Conky can display just about anything, either on your root desktop or in its own window. Conky has many built-in objects, as well as the ability to execute programs and scripts, then display the output from stdout. 
Conky is available for various Linux distros. The beauty of Conky lies in the fact that it can put just about anything - emails, appointments, disk usage, processor speed, temperatures - on your Desktop and make it look awesome. There are tons of customized scripts and configurations available online. In this post, I present some of the best ones that I have come across.
