Enriching our sights with hyperinformation is a logical next step after several technologies whose spreading we are right now witnessing, and becoming commodities : GPS, orientation, acces to databases. Using a monocle, glasses, a smatphone or even nanobots, all them ables to add text or graphic information to our viewing. We can now essay with wikitude or, virtually with Google Sky. The military has already being using it in its real everyday. And the natural for this technology is to be a strong commodity for future generations.

Imagine the social relationships, meeting guys/girls. We can say who we are interested in and, so, this person can notice our interest and, then add any kind of information downloaded from social networks. The chat would start far from scratch. Let’s add the pictures with coordinates included within the metainformation (as many devices are already doing) and associate them with the avies, this would mean our first talk sounding like old friends. And adding more and more technologies more features can be imagined, like facial recognition, with which, we don’t need to identify ourselves to be giving all kind of information about us.

We’d be watching a real documentary just looking a spot, thanks to the technologies above, when they’ll be really applied, getting information from wikipedia or semantic web.

And anything not being possible to be included into these reports, will be like prehistory.


El que més cueja al món tecnològic

Still wondering about what’s hot on the market, what skills and sectors are moving it, you can easily reach a not surprising answer.

2.0 is a strong trend and anything around it will create what now are blue oceans and in the future advantages on this topic will be worthy. So, web programming but as well as front-end, specially smartphones. J2EE and .NET are still demanded, like project management and web architecture. Some is said about Sharepoint. Bussiness Intelligence and Data Warehousing are raising, but I guess that’s for a close future. Systems are always demanded, specially for GNU/Linux networks, support personnel Helpdesk and desktop but green IT, cloud computing and virtualization are already waken up.

Fortunately the list of industries is longer, though it depends upon geographics.  Healthcare, energy, insurances, software development, government contracts and military, renewable energy, MLM, biotech and games are making the world go round, and they will still.

Dividir un fitxer en parts

%A %B %e%q, %Y – %I:%M %p

How to split a large file into parts? We’ll use rar.

$ sudo apt-get install rar

So we can split:

$ rar a -m0 -v350m myfile.rar myfile.avi

Where:

  • a : we are adding
  • -m0 : mode. 0 for no compression and fastest. 5 for high compression and slowest. 3 is default
  • -v is the size of the volumes

Uncompressing is easy:

$ rar e myfile.part1.rar

Parcelles al món rural

Yet another interesting approach for your android smartphone could be getting the outlines of a lot, or some of them using Google’s My Tracks. I couldn’t find a more proper tool, so I had to manage with it I’m I’m open to listen about a more focused app.

The use is easy. Once I downloaded My Tracks, I surrounded the lot, stored the track, uploaded to google maps and here we go! the track can be seen as the farm where and how it has to be. And even better, I could add a shape (closed!) precisely outlining my lot. This shape can be exported to a kml file. So, I can do anything, already.

Juntar fitxers pdf ordenadament

Sometimes I need to e-mail a document I’ve received by post mail. My scanner does not provide GNU/Linux drivers, so I must use the help of the Windows XP notebook available at home. I scan the document, get several files and store them in my kubuntu system.

But I want to send a unique document, so my recipient gets it easier. For that I use pdfshuffler. It is quit an easy tool, but it pays the bill.

I execute it with the command:

$ pdfshuffler

A simple screen rises, with four buttons:

  1. Quit
  2. Delete page(s)
  3. Import pdf
  4. Export pdf

I’ll use 3 of them:

  1. Import pdf(s): loading the documents in the same order I wish them to be paged in the new pdf
  2. Export pdf : when I’m done loading, I store the new file
  3. Quit: I’m ready to send it by e-mail

Can’t find bundle for base name

%A %B %e%q, %Y – %I:%M %p

A random day, fighting in the arenas of my own code, I first met this message:

Can’t find bundle for base name org.eclipse.jdt.internal.compiler.problem.messages, locale ca_ES

Glups. Does it mean anything? I guess so, but what, actually.

Sometimes my laptop can afford less than other times. Sometimes is eclipse who can less. Sometimes, both.

My app was working fine in local environment. But in the server this message raised among hundreds of lines in server.log. Yelling for attention. It didn’t ask to be understood, just handled.

The key word : eclipse. WTF is jboss asking for eclipse in the sever? Will he ask for X-gadgets, tomorrow? Mmmm. suspicious. Let me untrust eclipse for a while. Stop it. Wait. Start it. Wait. Recompile. Build the jar. Mmmmm, same size than before? Let’s check a diff. Voilà! The differ! Give it a chance in the server. Wowowo! It works!

What happened? Poor eclipse could not afford to build proper classes when he and the laptop where overloaded. Overwhelmed by the circumstances.

Anyway. Eclipse is still a wonderful tool. A great toy. Though sometimes is begging for patience.

When you get:
