Indefinitely offline

In case anyone is wondering what happened to me, I have some real life issues to sort out. I will have some basic internet access and email, but nothing fancy.
Hopefully I will be back online within a year or so. Until then! :-)

How to enable man pages search in Google

 I was messing around with Google this morning, when I realised that you can actually "subscribe" yourself to a custom search for linux manpages. You have to be logged in of course. :-)

 I say "subscribed" in quotes, because it's not really a subscription, but rather a pointless (my opinion) feature. The only good thing about it is the icon that you notice directly what you want to search, giving a simple explanation of what the command does - in other words, the title of the manpage.

 The steps are quite easy! You go to http://www.google.com/search?q=man+nmap and press the "Sign in" link on the top right corner. You log in with your Google account, then you are redirected back to the Google search page.

  Afterwards, you go to Settings ⟶ Search settings.

 Next, scroll down to "Subscribed Links" and click on the Subscribe button next to the "Unix Manpages". Click "Save preferences" and you're redirected back to the "man nmap" search. The search result is listed third here, so the result might be different than yours.



 Finally, let me justify why I consider this pointless. If you use Firefox, you can easily integrate a quick search keyword with your favourite operating system's manpages website. Not all of them have this feature/website, but Debian and Ubuntu have it!
 - Head on to http://manpages.debian.net.
 - Select Man -> All sections -> Debian Sid.
 - Right-click in the white text box next to "Man Page or Keyword Search".
 - Select "Add a keyword for this search".
 - Name: Manpages, Keyword: man
 - Click Save.
 - Head to your location bar text box and type in "man nmap".

Voila! Have fun keyword-ing!

Blogger and Firefox - How to save your password

 Some websites don't allow you to save your password in Firefox built-in password manager, for example Yahoo and Blogger. Really irritating!

 One beautiful day (my irony tends to build up under 35 degrees Celsius), I noticed that the Blogger page actually redirects you to a Google account sign in. Therefore, I've come up with this little link that will allow you to save your password and take you back to Blogger:


https://www.google.com/accounts/ServiceLogin?service=blogger&continue=http://www.blogger.com/

Someone might make a good use of it. I also hope someone will find a way or fix the yahoo login page. Enjoy!

P.S. Make sure you install Secure Login add-on - it's a really handy application that allows one-click installs!

Swine/Avian flu comeback?

We've seen  the avian/bird flu to "fly away" from the media attention, as soon as a new wave of infection, called swine flu, popped out. There exist 3 main "types" (genus / species) of influenza virus - A, B and C. Their "subtypes" (serotypes / strains) are really easy to merge with each other and create a whole new subtype, which isn't covered by a vaccine. If you still didn't understand it, imagine crossing a black cow with a white cow and ending up getting a black cow with white spots (or vise versa) - that's a rather simplistic comparison!

Now, CDC and the pharmaceutical companies (and subsequently the doctors that cooperate with them) warn about the widespread influenza virus infection. They expect the same or similar strains that have appeared so far. To some of you, this might look like "a big game" played by medicament-related companies. I have no idea what's going in the background and in the behind-closed-doors meetings, but one thing is sure: You have to be prepared.

Note for employers: this really concerns you, if you don't want to have insufficient personnel unexpectedly!
CDC has a well-written article about how should businesses and employers be prepared for the winter: http://www.flu.gov/plan/workplaceplanning/guidance.html




It may statistically be a pandemic crisis, but if people and public areas are well-prepared there's nothing to be afraid of. Quite honestly, I doubt anyone of you reading this post will face any serious symptoms. Surely pre-schools, schools and libraries can provide better hygiene control, teaching children how to wash their hands properly is a great way to start. Secondly, liquid hand sanitizers should be available in some rooms. Moreover, it should be possible to "recycle" the air in the premises, providing a fresh set every now and then; for instance, leaving a window open for a couple of minutes while on break.


Sneezing, coughing and even talking might expel liquid (droplets) along with some particles (droplets nuclei). One of the best ways to trigger attention while warning other people is to show why sneezing and coughing are bad, and some pictures of the actual moment are a good way to start:

- http://www.immediart.com/catalog/popup_image.php?pID=434



It's common sense that some people will get sick during the winter. That doesn't mean that they all will catch the bird or the swine flu. Babies should of course be taken care of and checked by a paediatrician, whereas adults and teenagers should also take precautional measures.

The easiest pathways for a micro-organism to enter our body is through the mouth, the eyes or the nose. The droplets from sneezing and coughing are really contagious. Therefore, "nose-picking", "eye-rubbing", "thumb-sucking" etc. should be avoided at all times; or at least until you get your hands cleaned! :-)


Also note that one of the first symptoms is almost always a sudden fever, followed by a runny nose/sore throat/higher fever after 8-12 hours; they might not all be expressed and might be in a different sequence!

There is one thing though in this whole bird/swine flu story that drives me nuts. The western capitalistic countries seem to be in a non-infective bubble. Many people in the least developed or developing countries don't have the adequate medical equipment nor the vaccines to combat and prevent the virus from spreading. Because of this, people might die, and only a few of us care. The media simply draw attention to what happens in the "western civilization", avoiding to show deaths that happen in other places of the world, where - under famine and food shortage - pathogenic micro-organisms spread wildly and only some of us provide help.

If the flu was just a marketing trick to cause mass hysteria and sell out their vaccine merchandise, I have a brutal comment for such companies, but then again I prefer not to  express my opinion.


Finally, I recommend taking the "Flu I.Q." test, it's a fun way of being informed about general information and facts regarding the influenza virus:

Workaround: brasero - slow speeds while burning

Brasero is a cd/dvd writing application for the Gnome desktop manager. Its advantages are ease of use, a lot of burning options and support for plugins!

Currently in Ubuntu 9.04, if you try to burn a disc, you might notice that:

• Everything goes well until about 50%.
• Afterwards, it continues, but the report does not show anything (empty progress bar).
• The speed is less than 2x, from 600 KiB/s to 800KiB/s, but the burning keeps going.
• Somewhere in the end, brasero shows progress again, but starts from 0%!!
• Burn was successful.

Note: You should consider that this might not always be your issue with slow speeds. For example, maybe your drive is not working well, or maybe your power supply unit (PSU) does not have enough "W" to supply all your hardware with adequate power.

The bug information is extensively reported here:
http://bugzilla.gnome.org/show_bug.cgi?id=582261

One of the developers detected and corrected the problem, which seems that it was using the wrong plugin ("wodim" instead of "growisofs"). Since Ubuntu's binary package brasero has wodim as a dependency, it might cause problems if you try to remove wodim.

There is a workaround though that seems to do the trick:

Don't forget to install the package for growisofs: dvd+rw-tools

1. Tell brasero to use growisof:
  - Press Alt+F2, and execute this command:

gconf-editor 

  - Head to apps ⟶ brasero ⟶ config ⟶ priority.
  - Change the number "0" next to wodim-burn to "-1" in order to disable it.
  - Change the number "0" next to growisofs-burn to "1" in order to set a higher priority.

2. Instead of using "Max" in speed burning options, set it manually at a high speed - e.g. choose 16x for a DVD or 52x for a CD.

That's it!

People are practically showing off where they got their songs on last.fm

I just stumbled upon the famous http://last.fm/ website - really great website that tracks down your audio preferences. Useful to show off your stats and music to your friends.
It's unfortunate that many people practically show off the origin of their (illegally downloaded?) songs, take a look: http://www.last.fm/search?m=all&q=www.

Makes you think again before posting your audio along with your personal information... ;)

Nikola Tesla: the forgotten wizard

To Nikola Tesla, a great Serbian-American who has given the basis of most electrical/radiological machines we use daily in our era. He provided the basis for an uplift of the way we live and work. Thank you, Nikola and happy anniversary.
