In order to learn more about Inscape, I search some video tutorials… say in Youtube!, and I realise that a “famous” cast was screencasters. Thus, I wanted to download the whole set of episodes… 106 of them!!!

Sure, you can try by hand, but I guess you will give up after clicking in half of them.

Then, I remembered this useful command in Linux, wget,which allows you to download files from the web. This one of those very-ultra-super-powerful commands in Linux, if you don’t believe me, look at the manual file,

 $ man wget

It is over 1500 lines! Clearly, you do not want to read all that for downloading some files!!!

Try then,

 $ wget -h

and you will get a short help.

In my personal case, the podcast to download are ogv files, and I found them all in the page screencasters, therefore I created a folder inside the Videos folder, called Inkscape, I moved to the new folder and run the command (all the step are below),

 $ cd Videos
 $ mkdir Inkscape
 $ cd Inkscape
 $ wget -nd -np -c -A ogv -r 
     http://screencasters.heathenx.org/wp-content/videos/ -l 1

Explanation

-nd : Stands for non-directories… it download the files in the current folder, otherwise wget will create folders corresponding to the URL address, for saving the files.

-np : Stands for no-parents… this is stay in the current folder, do not go up.

-c : Stands for continue… there are 106 episodes, I’d like to continue be able to stop… and the next time continue from the last on. Avoid to override already donwload files.

-A : Stands for accept… in this case the command will download only ogv files. You can give a list of different extensions.

-r : Stands for recursively.

-l : Stands for level… How many directories you want to into looking for your files to be download. In my case only 1.

Hope you can use this hyper-short post.

Cya soon.

Hi again!

In the last post I told you about my experience with Inkscape, and now I’ll show you how to install this software using the command line interface (CLI) in dabian-like linux.

Inkscape is include into the repository list, thus, the only thing we need to do is to open a terminal Alt+F2 and type terminal or Ctrl+Alt+t in Ubuntu or Mint.

In the terminal type

 $ sudo apt-get install inkscape pstoedit

Note that you will need administrator powers. I’ve include the package pstoedit, which will allow you to insert LaTeX formulas… in case you need them, but also allows you to manipulate encapsulated figures, like eps ones.

See you soon!

I used Inkscape a couple of time… just for fun, and I was impressed. However, last week I used it for some work-related stuff.

I wrote a paper, and the core of it was a numerical analysis of a set of differential equations. The solution was plotted, but the 3D manager of the software I tried was not wonderful, and the referee complained because the axis were not label.

Here the chaos began:

  • My plots were PDF files,
  • Somehow, the data files and program codes were missing!!!
  • After two months, I did not wanted to spend more time re-programming and running simulations.

Thus, the idea came to me, What if… I use a graphical program to insert the labels?

And I did!!!!

I tried first with GIMP, but it is a bit cumbersome… and the worst part is that I did not know hot to add LaTeX symbols. Meanwhile, Inkscape has and extension to render  LaTeX formulas.

I’ll be coming back to Inkscape. It’s great, so make sure to include it in your first aids kit.

Hello there! A long time without writing a post.

Today we shall install an extension for Inkscape, called JessyInk. This extension allows to construct vectorial presentations with js capabilities, which can be viewed in a web browser.

Installing the repository and package.

Open a terminal Applications->Accessories->Terminal (or Ctrl+Alt+t in the laster versions of Ubuntu), and type

$ sudo add-apt-repository ppa:jessyink-team/ppa

After enter your password, the repository is added and it automatically get the gpg key.

For refreshing the repository list, run (again in the terminal) the update.

$ sudo apt-get update

Finally, install the package,

$ sudo apt-get install jessyink

In a next post, I’ll show some features of JessyInk. Until the next time.
