How to wake up to music with Linux

I remember that, to finish my thesis, I had to get up at 3AM for over two weeks. I had to sleep in my office and I used my computer to set and fire several alarms: one to play a song at the desired time, another one to launch the browser, and a third one to open the thesis document. Back then, I thought Windows was a great OS because I was able to do all that. However, to be honest, it was not Windows that was doing the trick, but third-party software.

Now that I migrated to Linux, I realized that you can achieve exactly the same but directly from the OS, that is, without resorting to third-party software at all.

This is the way to do it:

1. Before the OS loads, press the key that the computer tells you to get into the BIOS. It can be DEL, ESC, or any other key that the system indicates. You have to press it quickly; you will be taken to a screen that looks like this:



2. Once in the BIOS, look for the Power Management page and follow the screen instructions to get "Resume by Alarm" or "Power On Alarm".
Set the desired time. Save (normally by pressing F-10), accept (yes) and then the computer reboots.


With this, the computer will turn on by itself at the desired time as long as it is plugged to a power outlet. That should be enough if you want the computer to wake you up. However, the idea is to make it play a song that you like and launch the programs that you need. To do that, you need to set some alarms in KOrganizer.




3. KOrganizer is hidden in Mandriva 2010 Spring. To find it, go to the bottom-right panel and click on the arrow to display it. KOrganizer, which is the program that will fire the alarms you set up, is a nice organizer that works pretty much like Outlook, only that KOrganizer is not so heavy on computer resources.







4. Once you find it, click to launch it and input the date and the time. You can just select the time periods as blocks on the schedule. Once you have set the time, you need to choose whether you wan to add an event or a "to-do" task. Actually, there is little difference for our purposes, but I normally go for "Add new event".







5. The following step is very easy: the alarms. There is a red icon that indicates the reminders.


You must click the box to be able to configure reminders. Once the box is checked, some options are enabled. Click on "advanced" to configure the time. Take into account that if the event is set at 8:30AM and you choose the reminder "5 minutes before the event starts", your alarm will go off at 8:26AM.

Now, if you want the computer to play a song for you, select "sound" and look for your song.
Obviously, you have to click OK to confirm and your sound alarm will be ready. If you want to launch your browser, select "application" instead of "sound" and specify the name of your browser. You can do the same for any other program.


I hope this tutorial saves Linux newbies like me some time when there is not any to lose ;-)

Smoke Screens and Linux

In my net surfings, I have encountered that smoke screens about Linux security are becoming popular. The way in which certain threat alerts were made public amused me. I believe that there was a malicious intention to discredit the Penguin OS using slanted information behind the sensationalist hype.

I found one smoke screen in Yahoo. The feature was a post titled: "Linux Trojan Raises Malware Concerns". I guess the point was to make Linux beginners question their choice. After all, if we migrate to Linux to feel safer and this OS is as vulnerable as Windows, why the bother? However, the strategy did not work so well because even Linux newbies could see beyond the alarming news. (You can read a Linux beginner's nice response about this story here). The original news read "a vast collection of Linux systems may, in fact, be pwned". Let's see:
1. According to statistics, Linux has the 1% of the desktop market.
2. The threat was neither found in the official repositories of "major" Linux distributions (Ubuntu, Fedora, OpenSuse, Mandriva, etc) nor in "minor" ones (Mepis, Zenwalk, Pardus).
3. Users had to download and install the infected file themselves from a site (This means we are not talking about MOST beginners, who are becoming familiar with the repositories of their distros).
4. The file is a tarball. For computer beginners, installing one of those is like changing the computer processor.
5. The infected file is for chatting using a specific platform.
6. The threat was not likely to have compromised enterprise Linux servers (where more Linux systems are found).

Then, what does "a vast collection of systems" mean here?

Why aren't people buying these things so easily anymore? I have the theory that, while the success of Windows was the ignorance of the user, Linux communities teach their users and this knowledge empowers people. After all, in the 21st Century, more computer users are awakening. Little by little, we are breaking this shell of fear and gullibility and we are beginning to see through the smoke generated to make us stumble. We read. We check. We double-check. We participate in forums and get informed.
Above all, beginner Linux users are abandoning herd mentality.
