Save Gmail attachments directly into your Google Drive

The idea is simple but genial: how about saving your Gmail attached files directly into Google Drive without wasting time and doing it manually? Not a bad idea but till now it was not easy to realize.

Today Armit Agarwal did it and explained how to do that!

Moreover, automatically adding a simple label to your incoming emails (e.g. labeling all the email from a predefined account or all the emails containing a particular word in the text) you can be sure that Agarwal script will save a copy of the attachments directly into your Google Drive.

But I don’t want to simply copy Agarwal ideas and tips about this new feature because you can directly visit his website and download the script he created.

Here I also like to focus your attention on the potential features offered by the App Script language by Google. In fact, Agarwal demonstrates how simply could be this Script language and how it can be used to add personalized and useful features to Google services (in this case: Gmail).

Try it and if you want to share new Google App Scripts don’t hesitate to add a comment or send an email to this blog.

Solve audio troubleshooting on Ubuntu and start planning to migrate to another Linux OS

1 Reply

It was just a simple system update which dropped off audio on my Ubuntu 12.04. It was really strange to admit that I had experienced a crash (better: an audio crash) on a Linux but the 12.04 Ubuntu actually caused similar problems to a numerous bunch of long-term aficionados around the world.

The real problem with the last Ubuntu versions is that this OS is not supporting properly “old” hardware as it did previously during so many years. Reading some other bug reports on the web I discovered that these audio troubleshooting crashes happen principally to “old” IBM ThinkPad and Dell. I hope Ubuntu developers will consider to solve immediately these kind of issues or many users certainly migrate to other Linux version.

In any case the best and complete guide to solve audio troubleshooting has been developed by Ubuntu itself. The guide is very detailed but, if you want to definitively solve this bug, you have to spend more or less 40 (forty…. sic!) minutes and follow all the 17 (seventeen… sic!) steps.

In my case the audio was back after the first step and I decided not to follow the other instructions but the audio troubleshooting comes back, more or less, every two months. Just to you if you want to spend 40 minutes only one time or a couple of minutes every two/three months.

When I consider all the problems I had with Ubuntu on “old” hardware starting from the 12.04 version, my advice is to start thinking about a migration to another Linux OS. I am testing some Ubuntu alternatives and in the next weeks I will post something about the tests I’m doing on old laptops. Stay connected!

Today opportunities

During the last two years the number of free online University courses exploded on the web. Today it is possible to attend prestigious courses by important USA and UK Universities and receive a final certification without spending a cent.

The good news are that these courses are interesting, well structured and you have a real possibility to increase your knowledge if approach them in the right way.

The first time you look for the free online University courses you are disoriented by the number and the many different topics they cover. The problem is to make the right selection in order not to waste time and energies for something you (and you career) don’t actually need.

How to select the right courses

1- Make a first selection between courses choosing only that are really interesting for you
2 – Check if you will receive a participation certificate if you complete the course
3 – Honestly evaluate your real, deep, interest for the courses that will not provide any written certification. I mean: “Do you really think that they will increase your knowledge and will be determinant for your career or life?”
4 – Don’t overestimate your capacities. Read very carefully the required background to attend the courses
5 – Don’t underestimate the time you need to attend the courses and do all the “homework” and the suggested readings
6 – Finally, select two (or more) courses and “Create” your free aside University career. Try to choose courses that have logical and “career path” connections between them. The important thing is what you are really learning on particular related topics you consider important for your career, not the number of disordered certification you can write on your resume.

How to install Ubuntu 12.04 on old computers with non PAE CPU

2 Replies

When I tried to install Ubuntu 12.04 on an old ThinkPad X40 I was surprised to discover this warning on my screen:

This kernel requires the following features not present on the CPU:
pae. Unable to boot - please use a kernel appropriate for your CPU.

In few words I wasn’t able to install Ubuntu 12.04 because the kernel on Ubuntu 12.04 was not supporting my CPU and I was really upset because I have always promoted Linux distributions as the most versatile and appropriate OS to keep using “old” hardware.

Sincerely, as described in an older post, I previously decided to install MATE desktop environment because the graphic cards on many laptops didn’t support Unity and Gnome 3 but this was the first time I had to renounce the installation of Ubuntu. I didn’t want to surrender to this difficulty (that appeared to me as a bug)!

First of all, I discovered that pae is “a feature to allow 32-bit x86 processors to access a physical address space (including random access memory and memory mapped devices) larger than 4 gigabytes“. After I clarified this point, I was not sure that my processor was totally inadequate to support Ubuntu 12.04.

After some web surfing I discovery that there are two easy solutions to avoid this problem.

1 – As first solution you can install Lubuntu (my choice) or Xubuntu on your computer then you can install the ubuntu-desktop using the Package Manager.

2 – If you prefer not to use the Package Manager you can install Ubuntu 11.04 or 11.10 and then upgrade Ubuntu to 12.04.

More in general, it is also possible to assume that if you have a non PAE CPU, your hardware could not be able to support the Unity desktop. For this reason you can keep your Lubuntu – Xubuntu (based on the light but effective LXDE desktop) or switch your desktop environment to Gnome (the Classic, of course) installing the gnome package instead of ubuntu-desktop.

In any case, if you want to know if your CPU supports pae you have to open a Terminal and type:

grep --color=always -i PAE /proc/cpuinfo

If something like “flags: fpu vme de pse tsc msr pae mce cx8…” outputs on your Terminal, you have a pae CPU otherwise your CPU doesn’t support pae.

The good third choice: MATE desktop environment. The traditional but rock solid solution for the Unity unhappy users (when also Gnome fails)…

My first Linux OS was a Knoppix but I had so many problems with the hardware drivers, the LAN configuration and the monitor settings that I was really discouraged. After many tests I decided that Ubuntu was the right OS for my notebooks and I continued to use it without any particularly matters till Unity.

Unity is nice to see, intuitive but if you use your OS in a stressful way (I mean doing three or four different tasks all together: reading emails, talking with Skype and writing on LibreOffice), you spend too much time looking for the icon you need to launch the right program. The vertical monitor space has not enough room to visually show all the icons related to programs I use everyday. Surely this is my personal matter but I actually prefer the “old” graphic interface. For this reason I decided to install Gnome 3 but my vetust IBM Thinkpad crashed a couple of time in a week.

To my surprise also the Gnome Classic option encountered some crashes due to the amount and diversity of the software I installed on my laptop during the last years.

As usual, after some web searches I found a solution: MATE. This particular desktop environment is a fork of Gnome 2 and it really looks very intuitive and easy to use. If some software conflicts with the MATE environment, a pop-up message will appear on your sceeen and, if you have the patience to read the Details contained in it, you will able to solve your problems. In my particular case (don’t ask me why) it helped me to focus my attention on Conduit which caused the crashes on Gnome.

To easily install MATE, on almost every Linux distribution, you can read its wiki dedicated page or directly follow the below instruction if you use Ubuntu 12.04.

– open Terminal and type these command lines:

sudo add-apt-repository "deb http://repo.mate-desktop.org/ubuntu oneiric main"

sudo apt-get update

sudo apt-getinstall mate-archive-keyring

sudo apt-get update

sudo apt-get install mate-core

sudo apt-get install mate-desktop-environment

When the Terminal finishes all the upgrade stuff, reboot your Ubuntu 12.04 and select MATE on the login screen (click on the upper right “gear” and choose MATE).

That’s all! Have a good week!

How to launch Pogoplug online services (as local disk) on Ubuntu 12.04 LTS

10 Replies

I confess that I use Pogoplug as cloud server for my external hard disks because it is really simple to configure and trustful. Unfortunately the Linux version of the Pogoplug management software is not so simple to configure and has fewer features than the Windows and MAC versions.

Running Ubuntu 12.04 LTS I can manually mount the drives I connected to my Pogoplug device, following the path Network –> Windows –> etc.., but sometimes this way is not so fast and moreover I cannot access to Pogoplug Cloud.

Waiting for an updated software from the producer I decided to use the current version to automatize the process and mount the drives connected to the Pogoplug and its cloud as if they were physically attached to my Ubuntu 12.04 LTS.

After a “classic” Google search on this topics I found different suggestions. Unfortunately I also had more than few problems to configure the software provided by Pogoplug because some tips were not so clear or easy as I desired.

By my experience, the fastest and reliable way to configure Pogoplug drives on Ubuntu 12.04 is the following:

– open Terminal and type sudo apt-get install fuse-utils

– open Synaptic Package Manager and be double sure you have yet installed these packages: fusesmb, fusedav, fuseext2, fusefat

– download the Linux software provided into the Downloads section of Plogoplug website, unzip it and save the file in your Home folder

– open Terminal and type: sudo usermod -a -G fuse $(id -u -n)

– log out and then log in again on your Ubuntu account to be sure that Fuse is correctly running

– open Terminal again and create a directory (in Media) to be used as mount point: sudo mkdir /media/pogoplug

– then type: sudo chown root:fuse /media/pogoplug

– and: sudo chmod 0775 /media/pogoplug

– in Terminal launch this command:

/home/yourusernameonubuntu/pogoplugfs --password yourpassword 
--mountpoint /media/pogoplug --user yourusername

where:

1. yourusernameonubuntu means you have to insert the name of User profile you use when you log in Ubuntu on your computer

2. yourusername and yourpassword are the username and password you use on the Plogoplug Website

Now, after some seconds an many automatic text lines, an icon named Pogoplug will appear on your desktop and you will be able to manage the online Pogoplug features as a local disk.

Don’t forget that you have to use keys -control+c- in Terminal if you want to disconnect from Pogoplug.

At this point the work is done but you might create a launcher icon in your (e.g.) Applications menu following this instructions:

– go to: System Tools –> Preferences –> Main Menu and click on the group (menu) where you want to create your new launcher (in my case simply was Applications)

New Item –> Create Launcher

Then fill the required fields with:

Type = Application in Terminal

Name = Pogoplug

Command =

/home/yourusernameonubuntu/pogoplugfs --password yourpassword 
--mountpoint /media/pogoplug --user yourusername

(as for the example above)

If you want to personalize the button you can also choose your favorite icon clicking on the picture on the left high corner.

On my side I also preferred to automatize the launch of Pogoplug command at each boot up in this way:

– go to: System Tools –> Preferences –> Startup Applications
– click on Add

– fill the fields:

Name = Pogoplug

Command = Same command line you used to start Pogoplug drive:

/home/yourusernameonubuntu/pogoplugfs --password yourpassword 
--mountpoint /media/pogoplug --user yourusername

(as for the example above)

So, starting now, you will have your Pogoplug drive connected each time you boot Ubuntu. You will not have any annoying Terminal lines.

Security Warnings: don’t forget that the data you move to and back Pogoplug, are directed through the web. This means that they could potentially be intercepted (and read) by third parties but it’s also necessary to specify that, if you configure it on the website Settings area, Pogoplug uses SSL (HTTPS) to encrypt the connection with its servers.

Anyway, don’t forget that the data you store into Pogoplug are not encrypted. If you want to join a better level of security you can encrypt previously your data or your disks using different softwares as TrueCrypt or the command dm-crypt (for more details on this topic also visit http://archlinuxarm.org/forum/viewtopic.php?t=1761&p=9723).

Don’t let them to track your internet behaviour! Use Ghostery for Firefox

1 Reply

We know that every time we visit a website we are caught by “invisible” robotized voyeurs which analyse our behaviour and share information to the site owner or to specialized data-collecting companies. These companies usually analyze the obtained information to improve the quality of their web service (in the most optimistic case) or to create a profile about the user with the specific goal to better sell services in the near future.

The real problem is that normally we are not able to realize what is happening. all this “ghost” activity happens in a silent mode without any tangible trace. To avoid this data collection and protect in a more efficient way our privacy we can use Ghostery, a specific add-on for Firefox and Chrome.

Ghostery defuses trackers, web bugs, pixels, and beacons placed on web pages by Facebook, Google Analytics, and more than 1,000 other ad networks, behavioral data providers, web publishers and companies interested in your web activity. As for every Firefox add-on, Ghostery is simple to install and manage. After the installation you can choose if you want to share anonymous information with the Ghostery servers to improve the quality of its services or if you prefer not to collaborate with them. You also can decide if you want to automatically update your Ghostery library and choose the specific trackers you want to neutralize. You can also create a policy for your cookies or (recommended) define a Whitelist for the websites you trust.

During my tests, Ghostery has not slowed the navigation speed in a sensible way also because I spent a little of time on creating a personalized Whitelist during my first use of this add-on.

Last but not least, Ghostery provides a very powerful information section where you can learn about any tracker it has blocked for you.

To conclude I can say that Ghostery is an add-on you must have on your Firefox to better protect your privacy!
