CDE

An useful application to easily pack and transfer code, data and environment to someone (using Linux and same architecture). Run any Linux program so that it can execute identically on another computer without any installation or configuration.

It’s not about package management or having a universal installer. It’s about being able to run your application in a different environment.

But why would you need this ?

  • Bug reproduction submitting an executable proof;
  • Develop on a certain machine and execute on other without bother;
  • Transfer a complete environment to a friend to execute a program or play a game.

Encryped Dropbox

11 November, 2010 Leave a comment

Wikipedia about Dropbox:

Dropbox is a Web-based file hosting service operated by Dropbox, Inc. which uses cloud computing to enable users to store and share files and folders with others across the Internet using file synchronization.

Err, what’s the problem?

This is a cloud computing service. There’s no garantee that my data is secure from others. So, it’s necessary to find a way to secure this data, as we can’t take care of unpermitted access.

After many tries to find a solution to turn Dropbox storage more private and secure, I finally stumbled on encfs[1] and gnome-encfs[2].

“EncFS provides an encrypted filesystem in user-space. It runs without any special permissions and uses the FUSE library and Linux kernel module to provide the filesystem interface. You can find links to source and binary releases below. EncFS is open source software, licensed under the GPL.” (EncFS – About[1])

Gnome-EncFS integrates EncFS into GNOME keyring, can mount an EncFS directory at login and is a open source software, licensed under GPLv3.

Combining these two applications it’s possible to save secure data in Dropbox.

How to?

Install encfs package (probably your distro will have it on package list). To use it:

$ mkdir ~/Dropbox/Safe

$ mkdir ~/Safe

$ encfs ~/Dropbox/Safe ~/Safe

Now go on gnome-encfs website[2] and install it. Later, type:

$ gnome-encfs -a ~/Dropbox/Safe ~/Safe

Now enjoy it!

The Walking Dead

The Walking Dead

No. I’m not here to talk about the new American television series. It’s quite the opposite actually, I’m here to explain why this television series is being filmed.

Robert Kirkman created this great work and Image Comics has been publishing  since 2003. Two weeks ago I discovered it and read 78 comics in almost one week(by The Pirate Bay). What is so great about it? This zombie apocalypse plot is just background of a great storyline. Rick, a police officer who needs to find ways to survive through this destroyed and crazy new world. The reality is: everything is messed up and everyone too. If I write more I will turn it on spoiler.

Wanna take a look? Watch part of episode 1 animated:

P.S.: I already bought two volumes at tfaw.com .

Swapper ported to Compiz++

15 November, 2009 1 comment

Almost one year ago we presented Swap plugin here. Now we renamed it to Swapper and ported to Compiz++ (future Compiz 0.9).

Just to remember that it allows you to swap the geometry of two windows. Basically we changed Switcher plugin to swap active window with another window.

Swapper could be inserted on new Compiz if everybody likes it. Waiting for replies!

Force of Nature

12 November, 2009 Leave a comment

Disc

Eddie Vedder said “Force of Nature” is “about the strength of one person in the relationship, when they can withstand some of the faults in another.”

Force of Nature / Pearl Jam (Backspacer)

Understand she’s a force of nature
Contraband hiding deep inside her soul
Exorcising her will to lose control
She lets go

A common man, he don’t stand a chance, no
Wonderland pulling Alice in the hole
No way to save someone who won’t take the rope
And just let’s go

One man stands the edge of the ocean
A beacon on dry land
Eyes upon the horizon
In the dark before the dawn

Hurricane has the trade winds blowing
A gale force shaking windows in the storm
Shipwreck on the rock that he calls home
With one light on

Somewhere there’s a siren singing
A song only he hears
All the strength that you might think
Would disappear,.. Resolving

One man stands alone, Awaiting
For her to come home
Eyes upon the horizon
In dark before the darkness meets the dawn.

Makes me ache,… Makes me shake,…
Is it so wrong to think that love can keep us safe?

Last I saw, he was out there waiting
A silhouette in the black light, full moon glow
In the sand there he stands upon the shore
Forevermore

Somewhere there’s a siren singing
A song only he hears
All the strength that you might think
Would disappear, resolving

One man stands along, Awaiting
For her to come home
Eyes are closed,.. You cannot know
But his heart don’t seem to roam.

Smart Put news

26 December, 2008 2 comments

Massimo Mund, Marco Diego and myself have been working on Smart Put plugin.

Smart Put is a kind of Best Fit algorithm to Compiz Windows. This plugins tries to find the best(largest area) gap for windows.

If it can’t find a good gap, Smart Put can(if option is enabled) :

  • Stack the window onto an underlying window.
  • OR shrink to fit.

And finally, Smart Put has a undo too🙂

All these new features were developed by Massimo Mund. Thanks man.

Here’s a video:

Video link

Try it out and tell us about any request,input,feature,…

$ git clone git://anongit.compiz-fusion.org/users/edgurgel/smartput

P.S.:  I’m working on a Smart Put port to Compiz++. Till there.

Swap

30 November, 2008 6 comments

Almost one month ago we presented New plugins. One of them was Swap plugin. Let me explain it better now:

Purpose

We were missing a plugin that could just exchange properties. Sometimes you just need to minimize a window and “unminimize” other. To do it, you would need to perform 2 or more clicks. So, we created Swap!🙂

Description

It allows you to swap the geometry of two windows. Basically we changed Static Switcher plugin to swap active window with another window.

Here’s a video to show what Swap can do:

P.S.: Forró is the genre of the music. Forró is a kind of Northeastern Brazilian music.
