More geekware

I've already talked about all kinds of geekware before, but this one sounds more interesting.

How about using QR-coded clothing to disguise what you want to say to the world and let only a few people to actually know what you're "saying"?

The Space Invaders-themed scarf shown in the picture on the left is a great example of QR-code based geekware.

Want to know what's this lovely girl's message? Well, install a QR-code reader on your cellphone and you'll be able to read it :-)

The day after Christmas

Had to much to eat or drink on Christmas? Well, web 2.0 can be a helpful diet programmer and provide you with the necessary tools to get back on shape and get ready to the next summer season (I know that's a few months away, but it's never to early to start thinking about it):

  • Fat Secret - Use your network of friends to help you recover your ideal weight
  • Diet Television - A bunch of information for getting you on the right diet
  • Traineo - Another friends' network to get support for training and diets
  • Wellsphere - Another social network for getting useful advices on day-to-day healthy habits

Arthur Benjamim: the "mathmagician"

Memory consumption on Firefox 3 will be improved

One of the main problems of Firefox is the memory consumption while loading and maintaining websites in view. A few minutes of using Firefox can boost up the memory to values over 100,000 KB.

But as a new memory test review that compares Firefox 2 with the new beta version Firefox 3 shows, the new version of the well-known internet browser will greatly improve this feature.

Can't wait for the stable version. This will be a really interesting upgrade :-)

The human calendar

Here's an original idea that uses photos of people with cards to display the current month's calendar: the human calendar.

And the most amazing of all is that it changes everyday to adapt to the new day, so the faces of all the people adjust their look to simulate as if they're watching to the correct date.

More tips to get some sleep while at your office

Remember when I gave some tips on how to react if you get caught sleeping at your desk? Well, I have some new ones:

Make it look like you have to tie your shoes:

Or pretend you need absolute concentration:

There are more here.

The truth about Web Design

For all of you that are now starting on the world of Web Design, have a look at what you're getting into:


The new most ridiculous/genius gadget in the world

In this past summer I suggested that the plastic popper gadget was the most ridiculous/genius gadget of all times.

However, I've found this new gadget that can seriously face off the competition: the Foot Mouse.

If you think that the number of buttons on your mouse are not enough and are limiting your potential to do great things on your computer, then the Foot Mouse is for you.

In the words of the creators, the benefits are:

- Speed up computer workflow in designing, editing, etc

- Hands-free computing and online surfing

- Enable people to multitask simultaneously

- Avoid repetitive hand/eye movement between hand-controlled input devices

- Much easier and faster shortcut entry (Multi-key finger control is replaced by 1-button foot control. Plus, no more eye/hand movement!)

- Reduce hand/wrist stress and help prevent/heal carpal tunnel syndrome or other injuries

- Keep clean/dirty hands off keyboard/hand mouse

- Give video gamers more "hands" to fight

- Offload hand work, outsmart hand mouse, outpace keyboard in shortcut entry

- A foot mouse with brain can boost your gain and kill your pain! It saves time and hands!

A new way of painting

Digital technology has been the catalyst to the change of our way of living. Who thought that 15 years ago, when we would send paper letters to our friends to tell them about our summer vacation, that nowadays doing that task would be as simple as attaching some pictures to an e-mail and send it and our friends receive the message in less than 5 minutes?

Digital technology can also change the way we produce art. And here's the perfect example: a new paint brush that uses a built-in camera and a special canvas to allow painters to create modern-day paintings by using the textures, colors and all kinds of surrounding elements.

This gadget basically “lifts up and captures photons”, allowing artists to draw with “special ink” picked up from their immediate environment.

Check out the video below to see the paintbrush in action:

Blow to control your computer

It's not as naughty as it seems! This new research is aimed at people with accessibility limitations, which allows them to control the computer by simply blowing towards its screen.

The system uses the microphone as the input device and calibrates it to distinguish sounds associated to the areas at which the user is pointing the blow at. Confused? Nothing better than a demo video to let you know what it looks like:

For those more interested in the scientifical/technical details or if you're looking for an implementation of your own, here's the link for the research paper.

What to say when caught sleeping at your desk

5 Best Things to Say When Caught Sleeping at Your Desk:

5. "They told me at the Blood Bank this might happen."
4. "This is just a 15 minute power nap they raved about in the time management course you sent me to."
3. "Whew! Guess I left the top off the Whiteout. You probably got here just in time."
2. "Did you ever notice sound coming out of these keyboards when you put your ear down real close?"

And the NUMBER ONE best thing to say if you get caught sleeping at your desk...
1. Raise your head slowly and say, " Jesus' name, Amen."

Have you ever noticed what you get if you put on your web browser? No, it's not Internet Explorer 7 download page!!

Windows on an ATM machine: is this really a good idea?

Having Windows running on machines that are supposed to be running flawlessly for a long, long time, might not be a good idea (as the BSOD in Frankfurt Airport shows).

Just this week, while I was browsing around for Christmas presents for the family in some shopping mall here in Portugal, I found this odd screen for an ATM machine:

Here's a magnification of the previous picture:

If you still can't read it, this is what it says:

"Windows NT could not start because the following file is missing or corrupt:
WINNT\SYSTEM32\CONFIG\SYSTEMHardware Profile\Last Know Good menu" (I don't know if this last word is actually "menu")

"You can attempt to repair this file by starting Windows NT setup using the original Setup floppy disk or CD-ROM. Select 'r' at the firt screen to start repair."

File Destructor: the perfect excuse

I don't even have to describe File Destructor. The words of the creators are self-explanatory:

"Want to play games on your Playstation but got a deadline for an exam or report that didn’t match your gaming ambitions? Then you have come to the right place. Send trashed files and blame your faulty computer, instead of confessing that you are a lazy bum who just wants to play videogames."

Geek stuff

There are geeks all over the world and they all have weird ideas. But sometimes, some of those ideas can actually be very funny or useful.

Check out this experience which uses the sound of sparks coming from tesla coils to play the Super Mario Bros. theme song:

And what about this guy, which decided to create a "Minority Report"-like interface by using the infrared capabilities of the Nintendo Wii controller?

Not to brag myself, but I still think that my GELToC solution is far more simple and elegant :-)

By using two led torches and a webcam, I was able to create an application that processes the light sources (from a dark background) and maps them into mouse control movements, which in turn are converted into Google Earth control movements, giving the illusion that you are controlling the World map with just a pair of tiny lights.

Check out a demo video:

GELToC is an open source application and you can obtain more information on it here.

Context-aware image resizing on GIMP

Remember when I talked about "Context-aware Image Resizing"? Well, now there's a free open source solution for GIMP.

Liquid Rescale plugin is a free, open source implementation of a context-aware image resizing algorithm. It aims at resizing pictures non uniformly while preserving their features, i.e. avoiding distortion of the important parts.

Check out a demo of this software in this screencast:

Free icons

The community offers a lot of free high-quality and creativity icons. Check it out.

Gadgets: there's one for every taste

The thing that I love about the Internet is that you can find gadgets for every taste (check this, this, this, this, this and this). And you don't even have to try very hard. Just search a little bit and you'll find a lot of interesting items, such as:

The flameless USB Zippo lighter (source)

The Hello Kitty Toilet Paper Dispenser (source)

The Static Electricity Eliminator (source - in PT, source - in EN)

The OhMiBod - an item for the ladies. It vibrates at the sound of your iPod music. What you do afterwards, it's your business :-)

Please, turn this sentence into an MP3!

If you need to create an MP3 file with an electronic voice saying a specific sentence, then vozMe is for you.

All you have to do is write a sentence on the website's form and then click "Create MP3".

You can also add this "Hear this post" kind of feature to your blog (as this blog will have from now on), by either using the WordPress plugin or the instructions to add this widget to Blogger. You can also add this widget to your iGoogle home page.

Retro-blogging: best posts of December 2006

Previously, on the Tech In Me:

iPhone in Portugal: yes, I tested one!

That's right, this a real iPhone and I tested it in a Media Markt store in Portugal. Sorry for the out-of-focus hands were still shaking from the excitement.

I have to say that, even though I've seen a lot of iPhone reviews, images and videos, I still ran into a few surprises:

  • It was thinner than I actually though it would be.
  • The resolution of the screen is absolutely fabulous. At the beginning, I even thought the menu that was displayed on the phone was a sticker. It wasn't until I touched the screen, that I could verify that this was an actually working iPhone.
  • The transitions between applications and menus are amazingly fast
  • Handling pictures with the multi-touch screen interface is even better than I expected
There were however some things I could not test:
  • There were no music files on the iPhone, so I couldn't test the "iPod" feature
  • The device wasn't connected to any WiFi network or GSM network, so I couldn't test the Internet access or the "phone" feature
And there were some things I didn't like (that's right, the iPhone is far from perfect):
  • Writing in the multi-touch keyboard is not simple. Your fingers get in the way of each other and you end up writing more than you wanted
  • The calendar is nothing special and it doesn't add almost anything to the calendar I have on iPod.
  • The iPhone gets a bit (actually, a lot...) smudgy after playing with it for just a while and you feel the need to clean it almost every time you use it. But I guess that's the problem with every multi-touch interfaces.
I couldn't fully tested because at this time a lot of angry eyes behind me were burning my shoulders enough for me to know that it was time to let someone else test it. It was even difficult to take a picture without a hand handling it. And in spite of the "downs" that I pointed here, it was a pleasure to finally test this device. But I'm not sure if it's worth to buy one once it gets available in the Portuguese market. It will depend on the price. Let's wait and see...

Future gadgets concepts

We've all seen our share of strange gadgets, which don't seem to have any special purpose other than to make you look like a silly person (as Monty Python would say). But every now and then you get to see some interesting gadgets concepts, such as the Projector/Cellphone and the mini MP3/CD Player.

The future of technology is all about these concepts and it is always entertaining to see where some of these ideas are heading. Check out the following images:

Here's a phone that takes the concept of "hanging up" too seriously:

What about this Nokia phone that looks more like a small sheet of paper?

Feel free to detach your laptop and work at a distance:

And what about this holographic display laptop from Sony Vaio?

Lemmings: the insanity is back

Continuing the wave of addictive games, who doesn't remember Lemmings, the stupidest creatures on the entire Universe that needed help to get from one door to another?

Well, now you can play it again, no matter which OS you're using, because the game is available on-line here.

Hitler and the iSketch

DISCLAIMER: the author of this post cannot be held responsible for the consequences that may be derived from the knowledge that you acquire by reading this, such as (but not limited to), the total and absolute addiction to iSketch, which ultimately may lead to the total loss of your social life. You've been warned. Continue at your own risk.

If you don't know what iSketch is, then it is best that you remain ignorant about it. Nevertheless, if you choose to continue, do so at your own risk (see DISCLAIMER).

iSketch is like an on-line Pictionary with the difference that you can play with people from around the world. It is highly addictive, very stressing but most of all, super-fun.

But as any addiction, the absence of the natural addictive element may have brutal consequences. To this day, people still think that the role of Hitler in WWII was due to some hatred towards Jewish people.

I was able to travel back in time and obtain the necessary proof to show you what the real reason behind Hitler's rage was:

The XBox Laptop

Just when you think you've seen all the geekery out there, a guy comes along with a crazy idea of turning a regular XBox 360 into a gaming console laptop:

Yeah, I know what you're thinking: "bahh! This is only a picture of a plastic-made pseudo-laptop photoshoped to make it look like an actual XBox 360 game is being played!"

Well, folks, you couldn't be farther from the truth. This is as real as taxes. This guy actually made this spectacular transformation of an XBox 360 into a laptop that you can carry around and play whenever you feel like it. And the best of all: he made a complete guide off of his 3-month experience:

And if you're still having doubts about it, check out the video below:

BSOD in Frankfurt Airport

I was browsing along my photo library searching for some work-related photos and I ended up finding this masterpiece:

This was taken the last time I passed through Frankfurt Airport towards some connecting flight, which was last summer.

I sure hope airplanes' auto-pilots are not equipped with the same software as these airport flight timetable displays :-)

Google Trends: what people are looking for on the Internet

Google Trends is a tool from Google that allows you to check the history of a specific term's search on Google in recent years. Such a tool allows us to perceive the tendencies of Google users throughout the years and in specific times of each year.

Interesting conclusions can be reached. For instance, if you search for the terms "stop smoking", this is what you'll get:

You can see that this search has more hits in the beginning of each year. Funny how people always try to quit smoking as a new year resolution :-)

A similar behavior can be seen through the term "diet":

People don't change: every new year's resolution are the same, either quit smoking or go on a diet :-)

What about if we search for other terms or people? For example, if you search for the "crazy socialite" Paris Hilton, this is what you get:

The highest point on this information search was in the beginning of 2005. That was due to the rumor that a certain "intimate" video of Paris Hilton and her boyfriend at the time was traveling around the Internet.

The other highest point was in the middle of 2007, when she went to jail because of being caught driving under the influence of alcohol.

If you search for the term "pope", this is what you'll get:

Funny how this term is relatively ignored by most Google users throughout the years and then suddenly it reaches a high point when the Pope John Paul II died (C) and then another high point when Benedict XVI was named the new Pope (D). After that, the term "pope" vanishes again from Google searches, only to rise once again when the new Pope decides to offend the Muslims (E).

But there are also things in Google Trends that don't really make sense. For instance, searching for "yogurt" will give you this result:

Can anyone explain why the term "yogurt" becomes uninteresting while close to the end of each year, only to rise again in the beginning of the following year????

And to end this already long post, why not search for something like "love":

No, it's not a coincidence that this term is most searched for by valentine's day :-)

You can also use it to post musics on your site such as this "hit" from Supermen Lovers:

The blind spot

We all have the so called "blindspot", an area in our field of vision that it's not processed by our brain. So, any element that is positioned in that specific area will appear invisible to our brain.

Don't believe me? Take the test then.
Cover your left eye with your hand and look at the star. Then slowly approach the screen while keeping your eye focused on the star. Don't look at the ball. As you approach the screen, you'll notice that there's a specific point where the ball will no longer be visible to you.

The all test and explanation is available here.

There's a person on this image...

... and he's famous. Can you figure out who?

I'll give you a clue: it's a man...singer...famous...already dead. Still can't guess who he is? Well, try backing up from the computer a bit. Ahhh, now you see it, right? :-)

Force Safari to open new window on a new tab

One of the things that annoy me on Safari is the impossibility to change Safari's behavior for opening links in new windows.

I got used to using tabs for everything on a web browser. So, Safari's behavior of opening "_blank" links in a new window was difficult to accept. After searching the web browser's preferences and being unable to find such an option I decided to look for a solution on Google.

I ended up finding this neat plugin that, besides showing a sidebar with thumbnails of the currently opened tabs (as the picture on the left shows), allows tweaking some of the options of Safari, including the behavior to open links in new windows.

To install this plugin, just download the ZIP file, unzip it, and (with Safari closed) copy the SafariStand folder into ~/Library/InputManagers. Then open Safari and you'll notice a new Menu Item next to the "Help".

On this new menu choose "SafariStand Setting..." and in the General tab choose the option "Open '_blank' Link in New Tab". This will avoid new window links to actually open on a new window :-)

P2P leads to more Music CD sales?

It seems that there is a clear link between P2P music sharing and the increase of music CD sales. Well, at least in Canada. A study (available here) shows that the use of P2P applications to share music, helps users get access to new music, which ultimately leads to an increase of CD sales.

The study concluded that about half of all P2P downloads were done because users wanted to hear an album before purchasing, or because they did not want all of the songs of an album.

Even though I may relate to that (because the 30 seconds available for each song on iTunes are just not enough), I hardly believe that this is the behavior of the common P2P downloader. It may be the case for the Canadian P2P file-sharing community, but then again maybe that's why Canada is such a great place :-)

Geek challenges

Today I have two geek challenges for you:

  • First, a very simple one. Do you think you type fast on a computer keyboard? Take the test and know your ranking...
  • Second, a more difficult challenge. Or should I say, "set" of challenges? Project Euler is a website that challenges users to solve mathematical problems by programming them in any desired programming language. Users are rated according to the number of challenges for which they find a solution. There's even an international score board where you can see where all the users stand and how many challenges they have solved.
Have fun!

Are you a heavy P2P-downloader? Maybe you should be insured!

Apparently, a company in Sweden is offering file-sharing insurance. But what's "file-sharing insurance", anyway? It's simple, you pay around $19(13€)/year and the insurance company will pay your fine in case you get sued by a copyright-holder company or representative such as the RIAA in the USA.

This might actually be a good business for both sides, since the probability of being sued by RIAA is 1 in 1840. So, the insurance company may end up with a lot of money but you pay only a small yearly amount and you have a "jail free" card, just in case...

A different kind of game...

The gaming industry is constantly evolving and new concepts are emerging that may revolutionize the way we interact and play games. Playstation's motion camera EyeToy and the motion-awareness Nintendo Wii's gamepads are just two of the most recent examples.

Augmented reality, a concept that exists for a few years now, may be the key to deliver new gaming experiences as the mix between the reality and computer-generated data promises to deliver new ways to interact with games.

A New Zealand digital artist, Julian Oliver, is working on a cool game that blends the electronic universe with the real world. By using a cube with special symbols and a webcam to film it, he presents an interesting game where the user must help a digital player move around in a 3D maze. Check out the video to get a full understanding of the technology:

Apple Store in Portugal...or is it in Spain?

Now that we have an official Portuguese Apple Store, hopefully we'll have the same opportunities and support as in other countries.

But this Apple Store doesn't seem to be that much Portuguese. It looks more like a bad translation from the Spanish store. Here are a few snapshots of the website where you can see that a few Spanish words can still be seen and that Spanish sentence formation are still present even though the text is already in Portuguese:

Update: And here are a few more:

Interesting how a store that only has one day, already shows advices about what other users have Spanish:

And this one is particularly interesting since it joins Spanish and English, in a "Portuguese" store:

Oh good, let me be the first to comment a product...maybe I'll do it in Spanish:

The end (or the beginning) of the world is close!

The launch of the most complex scientific instrument of all times, which was due this month, is now scheduled to May 2008. The Large Hadron Collider, a 27-km ring tunnel built deep underground between the Swiss and French borders, promises to recreate the conditions right after the Big Bang. By revisiting the beginning of time, scientists hope to unravel some of the deepest secrets of our Universe.

Since on March this year, a pressure test of one of the "inner triplet magnets" (whatever that is) failed, the team decided to extend the experiment to make sure everything goes as planned. And they better make sure that everything will work as planned, because otherwise, we might be looking at a new Big Bang and I'm pretty sure that wouldn't do wonders to France and Switzerland's landscape. Or the Planet's, for that matters.

Nevertheless, the successful ending of this experiment might reveal the answer to the ultimate question: how was the Universe created? While some authors have interesting theories about the beginning of the Universe, we can only wait to see if the most complex experiment of our world will shed some light on the subject.

If you're interested on knowing a bit more about this experiment, check out these videos:

Quick tip for importing addresses into Thunderbird

I recently needed to import my Address Book to Thunderbird, but using CSV format was a real pain in the "bottom" and a lot of errors were showing in the final result.

If your previous Mail program uses a vCard format it's better to use this one as it is widely accepted. And yes, I know that Thunderbird doesn't support it. That's where the tip comes in :-)

Use this on-line conversion tool to convert your vCard-formatted address book into the LDIF format which is accepted by Thunderbird. Guaranteed success :-)

The Mac in Me

I'm officially now a Mac Switcher. My MacBook Pro has finally arrived and I will now enter the realm of Apple. It's my first experience at it and I bet I'll feel strange at the beginning after so many years of being a Windows user but hopefully I won't regret this decision.

It might take some time now to come back to regular posts on this blog. It will depend on my level of adaptation to the new Operating System :-)

Blue Screen: Apple's Leopard has it too

Apparently, the BSOD (Blue Screen Of Death) is not a Microsoft's exclusive. Recent reports of users that tried to upgrade to the new version of Mac OS X, Leopard, point out to a very annoying Blue Screen freezing problem on the installation process.

In fact, Apple has acknowledged that there are some problems with the installation of their new operating system. But they point out that the problem may be related to APE (Application Enhancer). So, if you're trying to upgrade to Leopard and you are faced with the BSOD, follow Apple's instructions for booting into single-user mode to remove the offending software.

The fact that this seems to occur only to users that are trying to "update" instead of making a clean install, rises the everlasting doubt: should we upgrade or clean install our operating systems?

There seems to be a general opinion (mine included) that "clean installs" are always safer, mainly because "upgrading" is the installation method which will most likely leave files in the system that are incompatible with the new OS. Hence, unless users have the necessary tech knowledge to know which files will cause incompatibilities with the new OS, it's always better to perform a "clean install".

But still, "upgrading" has a very compelling argument: you get to keep your personal files - no need to retrieve them from boring, lenghtly and difficult backups. Anyway, Leopard will probably be the last "clean install", you'll ever make as the new "Time machine" feature in Leopard seems to be a work of art when it comes to backing up your data. It is simple and easy to use and it works on the background as if it wasn't even there. The simplicity of it all is even more evident when you plug in an external hard drive. And in the end with all your data easily backed up and manageable on a external hard drive, upgrading to a new version of the OS is a piece of cake.

Installation problems aside, it is also a general opinion that Leopard is a great advancement comparing to its previous version, Tiger, but not as mind-blowing as it should. And that leads to the obvious question: is it better to make smaller but constant improvements on the OS (as Apple has done in the last five years with constant updates of Mac OS X) or to make giant leaps that can totally change the view that people have of their OS (as Microsoft did from 98 to XP and now to Vista)?

What's your opinion?

Geek thought of the day

If only we could use computer shortcuts in real life...CTRL+Z would come in handy sometimes.

Your mobile phone as QR-Code reader

Hello, if you liked this post, please consider subscribing my RSS news feed. Thanks.

QR-Codes, the popular Japanese 2D bar code technology, can now be used on mobile phones. For those of you who don't know what a QR-code is, I'll give you a little example:
This strange-looking figure is in fact a complex storage system that allows to encode data in a picture. In this example, reading this QR-code will give you access to this blog. How? Simple, the disposition of these black dots on the diagram can be scanned and translated to text, which in this case, translates to a URL:
This kind of technology is quite common in Japan and it can be seen in the manufacturing of cars (to allow robots to identify the parts that need to be assembled), in supermarkets (to allow people to read more information on the products they want to buy) or in museums (to allow visitors to have access to more information on an exposition).
This technology is now available for mobile phones and it's incredibly fast and easy to use. I tested with my Nokia N80 and it worked perfectly.
If you want to install a QR-code reader on your cellphone, check this site (make sure your cellphone is supported, remember this only works for camera-enabled phones)
Once you've installed the software on your phone, test it with this code I have here:
I can only say it's a funny joke :-)
Are you wondering how I created the QR-codes for this post? Easy, there are a lot of QR-code generators available here, here, here and here.
UPDATE: it has come to my attention that RSS readers may not be able to see the pictures on this post (depending on the RSS reader that you're using), so just in case, use the direct link.
