Dropbox, is for Linux!

Dropbox is a online storage system that also synchronizes a folder in your computer. Thus, it can synchronize files that you have on multiple computers, imagine: your music folder is the same on your laptop and home computer, when you grab some new songs they “virtually fly over from one computer to another” at the speed of an internet connection.

The service is very interesting and actually good, they offer 2Gbytes free of charge, and of course you can be tricky and make multiple accounts and so forth. But actually 50Gbytes are so cheap that I’d strongly advise to thing twice and maybe spend a few dollars from your pocket.

Full Linux Support

Yep, this is how contemporary apps sound like (and should be). Go to their website and download the Linux Dropbox version, install it. It will run a small “tour” installation program that allows you to create or link to an existing account, and customize the place for the Dropbox folder (this is the folder that will be automatically updated and uploaded/downloaded).

(dropbox being used, double click the item and your folder will appear)

Also if you use a Window Manager called Gnome (this is the part of the Operating system that takes care of the visual aspects of your Windows and running programs) you can install an add on. The add-on is called nautilus-dropbox and is very useful, it allows you to right-click on an item in your dropbox and access some neat shortcuts, such as “get public link” which is extremely useful to share things with your friends.

(installing the nautilus-dropbox plugin via synaptic, use whatever installer you like the most!)

Dropbox in Linux, sounds like a sea of possibilities

Of course, like everything in the open-source community there’s a lot of scripts, add-ons and cool things to use along side the standard dropbox. A bit after started using dropbox (more than one year ago) I developed a simple script that allows to: “zip a folder” + “move the zip automatically to the dropbox public folder” + “return the public link” ! Since this is all very basic, I just noticed that it is already available on the add-on section of the dropbox siteshell script that uploads to public folder!
And if your really hardcore Linux (then you’ll probably won’t find anything useful in this blog) you can install dropbox in a entirely text based environment, see this tutorial (no graphics!). This is cool if you manage a server and want to use dropbox, or share folders with your users.

After some inactive time!

Well everything is back again, a lot of inactivity time, but that’s for the best of reasons:

– finishing up Master thesis, and learning a hell lot about Linux!

Hopefully I’ll continue to post some interesting (and simple) Linux thingies (applications, tutorials, explanations, and so forth) here!

Sound Manager (OS sound mixer…)

Like Windows Vista and 7 (that benefited from a refurnish of the Kernel Sound Module of Windows – that had been needing repairs ever since.. see a bit more on my thesis blog) Ubuntu also has a mixer that:

  • allow you to confgure the sound level of each application independently (see screenshot below)

There it is, I can choose levels for Media Player (audacious) or the youtube video, independently.

Have fun.

“Motivational” Screenshot

Just posting a screenshot of the current system “look and feel”. Already a bit customized (sensors for temperature and some cool task-bar widgets.. more on that later)

(Emotive) Opinions on Ubuntu 9.10 Install vs. Windows XP SP3

Okay, the system is running (see instalation guide on post below).

As far as this point there are a few emotions that come into play when using Ubuntu 9.10 for the first time:

  • Automatic Driver install (every driver: sound, wi-fi, ethernet, modem, graphics, etc… was installed without worries)
  • An incredible HUGE bundle of applications already included (almost every thing you wish to do is already available).
  • Very fast system. From the moment you boot to the login screen and then till you reach the desktop, you have a clear feeling that this is way faster than Windows Xp Sp3 fresh install (by other Operating System).
  • Easy new program-download. If you need something, just open a widget and choose the program. It downloads and install it for you! Super easy…
  • No cracks, no serials, no hidden tricks… this is Open Source software, Free as in free beer.
  • Fully customizable stuff, in 2 minutes I downloaded a new theme and got the system preferences more the way I like (even windows behaviours and icons).
  • Democratic system, when you install Ubuntu or other Linuxes – they play along nicely with Windows or other Operating systems previously installed (automatic confgure of GRUB bootloader lets you choose your system when you boot.)
  • No stress confguring network access: nor Wifi nor ethernet!!!

If you are a Windows user… imagine: installing a system (on an older laptop: about 2/3 years, with AMD processors) and when you boot the first time… you can use the web (already have Firefox), you can create music (ardour, jack, rosegarden, audacity, etc..) you ca draw 2D or 3D (inkscape, blender, the gimp), you can watch movies, listen to music, and so on… and….if something isn’t the way you like. You are openly invited to re-configure-it.

It’s not a dream… it is just a different paradigm for using a computer. Think carefully, maybe you’re looking for a Linux, and freedom.

Installing Ubuntu 9.10 (Karmic Koala) Studio Version

Starting point: This is a guide to show how to install Ubuntu 9.10 Studio, using manual partitioning and with a previous Windows XP already installed. (read previous posts for more information on Windows + Linux)

a) if you’re planning just to try Ubuntu Studio you can use it on a Virtual Machine (caled VM) but I don’t recommend it. VM’s are emulations that allow you to run an Operating system inside that emulation-application (the VM host) – as all emulations they run slower than a real system – in the case of Ubuntu studio it’s almost ridiculous  to install a RT kernel (see previous post) and then run in slow on a VM.

> But… nevertheless.. If that’s what you want: use a virtualization such as VirtualBox.

> There’s also Wubi, an application for installing Ubuntu’s inside Windows. But once again for the same reason, you’ll loose the beauty of Ubuntu’s fast / low latency workings.

b) The REAL deal, let’s install Ubuntu Studio 9.10 (Karmic Koala).

b.1) Go into their website and download the latest stable (which is 9.10 now).

Notice: Ubuntu Studio has no LIVE CD, like the typical Ubuntu, so there’s not the usual “Try it without installing” that you see when you boot a Ubuntu live CD. To try it without messing something up (not likely to happen if you follow this guide) choose opetion a) and virtualize it.

b.2) Burn the ISO image to a DVD using your favourite program (I use InfraRecorder).

b.3) Put the DVD in the DVD-drive and start up the computer. Acess BIOS (usually F12 hotkey) and select “Boot From CD/DVD”.

Notice: yes… no CDs my friend. If you do not have a DVD reader – boot from a removable media by configuring it in your BIOS/boot option.

b.4) You’re ready punk? Let’s begin.

c.1: On the screen above, just select “Install”

c.2: Then obvious instructions for selecting Language.

c.3.: Obvious selection of country.

c.4: Fun Part: selelect “Yes” and press keys such as “+”, and it automaticly detects keyboard layout (my case is PT).

Notice: I have no clue why Windows installer does not include such a functionality…. uf.

d.1: Now it is booting and checking to continue the instalation process. Just wait.

d.2.: It tryies to automaticly retrieve the network info via DHCP, it can fail but there are two alternate methods:

d.2.1) Try again with DHCP but with hostname. (usually works – you need to now the networks name)

d.2.2) Try manually (insert IP, Subnetmask, and all the configurations – allways works if you do it properly)

Notice: if you are running a Windows operating system near you go to teh console (Windows_KEY+R and cmd +ENTER) and type “ipconfig /all”. The OS will give you all of the info above (IP, gatewys, mask, names, and so on..) In Linuxes the similar command is “ifconfig”.

d.3.) After network is properly working it asks for a name, this will be your computer’s node name on the network. The example shows softpedia name (the website that provided the screenshots for this guide)

e.1.) Now its partition time (access my post on partitioning opinions/schemes), here I advise you to choose “Manual”.

e.1.1) “Manual”: Simply choose the correct partitions and perform the desired actions. I suggest:

“Koala” partition for Ubuntu OS (at least some 10GB to be confortable) – Logical Drive – EXT4 Filesystem – Mouny Point “/” (means root partition – very important)

“Swap” partition for Linux pagefile (double of the RAM is the thumb rule) – Logical Drive – Linux-Swap Filesystem – Mount Point “/swap”.

“Data” partition for you data (whatever size) – Logical Drive – EXT4 – Mount Point “/home” ( a Linux common name).

e.1.2.) Then choose “Write the changes to disk” and it will format the drives for you.

i.1) The Install is almost happening!

i.2) Fill up UserName + logon name + password + timezone, etc. etc… The usual stuff.

i.3) The real deal: pay attention. Use SPACE BAR to select which packages you want to install. And only press ENTER when you have selected the ones you like. (suggestion: ALL!)

Coffee break.

i.4.) GRUB 2 bootloader: It will ask you to install GRUB, say “Yes“. And Ubuntu will automatically install GRUB 2 and keep up Windows and Linux side by side. (dual boot)

IT IS OFFICIAL: You’ve JUST MOVED TOWARDS LINUX.

Ubuntu and Ubuntu Studio – 9.10 the “Karmic Koala”

First a short intro: Ubuntu is a Linux distribution, which means open source and free operating system. An amazing OS that is being widely accepted and showing great results in the community.

Ubuntu Studio is an official derivative of Ubuntu that is targetting the multimedia development/production (audio, video, 2d, 3d, etc..) the major differences are a HUGE application list already bundled and the RT kernel patch (means Realtime kernel – giving the possibilty to achieve less latency in audio/video processing).

Note: You can upgrade a “normal” Ubuntu to Studio by installing the “ubuntustudio-desktop” package.

The latest version is 9.10, kindly called Karmic Koala (get used to distribution names, they are better/sexier than numbers) – in both Ubuntu (the main) and Ubuntu Studio (the derivate).

Small note: The next is 10.04 and will have a lesser name (in my opinion, ’cause I’m a fan of Koalas): Lucid Lynx – scheduled for April 2010.
