Cleaning up the house

This particular blogger weblog is, as you may have noticed, defunct. I decided to aggregate all my content in my own personal weblog. Although my personal weblog has bits of non-tech related news, the "Tech in Me" RSS feed remains the same and will only be filled with tech-related news, so there's no need to change feeds.

Nevertheless, if you're interested in other subjects like funny stuff, movies, tv shows, books, games, etc..., you can always subscribe to my full RSS feed.

Google Wave Invitations

I've been using Google Wave for a while now and they were kind enough to send some invitations for me to distribute around. So, I have 3 left. If you want one, just leave a comment here or send a reply/DM on Twitter with your e-mail address.

Geek alert: I'll be using FIFO as the sorting protocol in case there are more candidates the number of invitations. Good luck :-)

How the use of technology can be so natural for us these days

My brother has recently had an experience that perfectly describes how technology can be so helpful and natural to use for most of us. It's quite amazing. Read it here.

How to solve a wifi issue between Nokia 5530 and a Thomson TG787 router

So, my wife bought a Nokia 5530 Xpress Music phone and was very eager to try it, especially the Wifi since she could now connect to Facebook and e-mail at home without having to use my Mac or iPod Touch :-)

However, the experience was not that thrilling since the phone was unable to connect to our our home router (a Thomson TG787 provided by our ADSL provider).

After trying several different configurations (with WEP, WPA, WPA2, without encryption, etc...) and with other gadgets (iPod Touch and Nokia N80 could connect successfully to every configuration) I was very frustrated that I couldn't find a working solution.

At that point I went out and while at a shopping mall I was able to try some public wireless networks and it worked immediately. This increased my frustration to an even more absurd level. Back home, the problem remained.

It was only when, while using some Google-fu, I was able to find this forum post (in Portuguese) that I could finally solve the problem. Even though this post refers to the Nokia 5800 Xpress Music, the solution appears to be suitable for the 5530 model as well.

So, basically all you need to do is some Terminal action:

  • Open Terminal (on a Mac) or a command window (in Windows)
  • Run the following command: telnet
  • This will give you access to the router, but you have to insert the username (Administrator) and password (the password you defined)
  • Once an administration console appears, write: wireless qos config mode=disabled
  • Then hit Enter
  • After that (it takes a few seconds to compute) write: saveall
  • Then hit Enter
  • Just exit and you're done
The Nokia 5530 phone was able to connect to the home wireless network... success, finally!

Final note: I don't know exactly if this affects only this type of phones, but my Nokia N80 worked fine without the need to do this hack. Also, I don't know exactly what this hack does to your router so beware. So far, I haven't noticed anything different on all other devices, so I won't reverse it. By the way, if you need to restart your router, this configuration is lost, so you'll need to do it again.

An amazing moment in time

Did you notice that an amazing moment in time has just passed? And what moment would that be, you ask?

Well, have a look at today's date and time. The day is September, 9 of the year 2009, that is:

Cool, isn't it? The next moment in time like this one will only occur next year, on October, 10th of 2010.

Ahh, beautiful 2008 Summer nights!

The invisible flash

Using the flash while taking some photos may be, in some situations, the only choice you have in order to produce decent lighting in a picture. However, most flash pictures are ruined because of the excessive light in the foreground and not enough light on the background.

In the ideal world of photography, a camera would be able to capture just enough light to make the picture perfect but not suffer from the disadvantages of using flash. Basically, what we need is an "invisible flash". But how can one produce such a paradox: a blast of light but that is not visible?

The answer is given by a student of the New York University, Dilip Krishnan and his advisor Rob Fergus. They have developed a dark or invisible flash which uses infrared and UV light to take photos in dark places without the nasty glare of a standard flash.

Basically, what they did was modify a light bulb to emit light over a wider range of frequencies (not visible at the human eye). They also changed their camera to adapt to these new conditions by using a set of filters to prevent the silicon image sensor from detecting infrared and ultraviolet rays.

This is not exactly new as this is more or less like night vision works. The difference is that, instead of having those photos where we all look like vampires, they managed to find a way to produce the correct colour balance by taking a quick colour image right after the dark flash image.

Even though the image produced in this second image is of low quality (grainy and unclear), the colours are correct. This allows them to produce a correct final image by using special software that combines the information from the photos (you can see the process on the 3 images above).

The technology is not yet perfect but it definitely looks pretty promising. To know more about it, you can check the website here.

Anti-paparazzi gadgets

Adam Harvey, a student of of Interactive Telecommunication at New York University has created a new gadget that will probably be the next sensation of all those paparazzi-harassed celebrities: a purse with a flash sensor and flash.

So what does it do? It's simple. The purse contains a sensor that is triggered by any flash going off, and it instantaneously fires its own flash, completely ruining paparazzi shots.
