The way I did it:

1. Open your favourite browser
2. Go to twitter.com
3. Log in
4. Write a tweet

I’m a Linux user and I love the terminal. Wouldn’t it be better to write tweets from the terminal? – Yes it would!

I have written a quick and dirty python script that enables you to write tweets from the terminal.

You can download the script here.

Install guide for Debian:

Step 1: Download

$ wget http://dibon.net/tweet
$ chmod +x tweet
$ sudo mv tweet /usr/bin/

Step 2: Install curl

The script uses curl to send data to twitter, if you don’t have curl installed you have to install it:

$ sudo aptitude install curl

Step 3: Make the config

Make a file called “.tweet” in your home directory:

$ vim .tweet

And insert the following:

[login]
username = YOURUSERNAME
password = YOURPASSWORD

You may want to edit the permissions for the file

$ chmod 0700 .tweet

That’s about it. You may have you reopen your terminal window before you can use the tweet command.

Usage:

$ tweet "I'm writing a tweet in terminal!"

Unfortunately it is necessary to use single or double quotes before and after the message.

The puzzles are sometimes very non-intuitive, and is mostly results of bad API’s or other strange features. Some of the puzzles aren’t very useful, but it’s always nice to have a deep understanding of a programming language.

Watch the talk a YouTube:

I’m looking into Python for two reasons. One; I want to expand my knowledge of programming languages. Two; Next term I’m taking the course Introduction to Algorithms where Python is the language we will be using. It’s always nice to have a head start.

Update:

It turns out that the professor teaching the course has written books about Python and also written a short tutorial. Click here for tutorial.

To make a snippet you have to define a tab-trigger which is a word or a random sequence of characters that you will remember. Then you have to write the snippet body.

Easy example: If and else statements. When you write “ife” and press tab you want an if-else statement to pop up. We write the snippet:

$0, $1 and $2 are where the cursor will be placed. When you first type “ife” and press the tab button the cursor will be where the $1 is. If you hit tab again the cursor moves to $2 and so on, but you always ends up at $0. Now you can use this snippet whenever you need it. Just write “ife” press tab and fill inn the code you need.

More advanced example: Lets say you are getting tired of writing all the code for a for loop every time you need one. Make a snippet!. We set the tab-trigger to be the string “for” and write the snippet:

What the ${1:i} does is that it sets the 1st cursor position and sets a default value (“i” in this case). The default value is marked, so when you tab to the position you can immediately overwrite the default text. And an other thing in this example worth mentioning is that we use ${1:i} more than once. This enables you to change the default at more than one place at once. Let’s say you don’t want your variable called “i”, but “index”. You still just write “for”, press tab, and “i” is marked. You now write “index”, and the “i” in all 3 places where it’s used will change to “index”. Then tab again to set the start value of the for loop, and yet again to set the max value for the loop. After choosing variable name, start value and max value you just have one tab left. The last tab brings to you $0 and you’re ready to write some code inside the for loop. If you tab one more time while the cursor is at $0 the tab sequence will start over.

Personally I like the same preferences that Micah uses. I enable indent with 4 spaces, turn of line wrapping and enable line numbering. Read a more detailed description in Micah’s post.

Plug-ins I use:

- Gemini
A plug-in which auto-completes parenthesis, brackets and so on (the characters: < { [ ' " " ' ] } >) and nicely indents and places the cursor where you (me) want it. This plug-in is an absolute life saver!

Before return is pressed (notice that there is no “}”):

{//Cursor here

After return is pressed:

{
    // Cursor here
}

- Symbol Browser
Shows a list of classes, functions, enums and class fields.

- Snippets
This plug-in allows you to define snippets of codes which appear when you use a tab-trigger. This one saves you a lot of time. Make a for-loop with a few keystrokes. See my post on how to use snippets.

If you use an awesome plug-in or something for gedit please leave comment!

I just realized how powerful jQuery library is, and I will definitely start using it.

See the clip on YouTube:

Wish I was that smart when I were twelve years old :-|.

To get this working I had to write a little plugin for WP, which was easier than I thought. Here is the code I’m using:

WP need the comment to get data about the plugin and you simply use the add_filter() to apply your own function on given data. Here I’m using addLatex() on the content.

Here is how it works:

[ tex ] V_{ind} = -\frac{d}{dt}{\int_A{\vec B d\vec A } = -\frac{d\Phi_B}{dt} = -\frac{d}{dt}\left( \int_{a+vt}^{a+b+vt}{ \frac{\mu_oI}{2\pi x} cdx \right) = … = -\frac{\mu_0 Ic}{2\pi}\left( \frac{v}{a+b+vt} – \frac{v}{a+vt} \right) [ / tex ]

You gotta love LaTeX, and you gotta love physics. This equation is actually the solution to a problem on an old exam.
