The Boulder Creek Inspires People..even to Pee!
Today, walking by the Boulder Creek, I saw some people doing a photo shoot. It happens often around here, especially when young couples take their engagement pictures. It was inspiring.
Apparently, I was not the only one inspired by it.
The man in the orange coat decided to pee in the river next to the couple’s photo shoot in full daylight!
Free Wifi and Toolbars are Used to Monitor the Pages you Visit
If your browser sports a toolbar (e.g., from Yahoo, Google, MyWebSearch, …), you are using Google’s Chrome browser or the free WiFi that they offer in Airports an planes, somebody is gathering data on the pages you visit, how long you stay on them, and what else you do online.
This is the sometimes shocking truth that most people ignore when they use free web products without wondering why and how those companies provide them for free.
Afterall, if you think of it, to install that wireless connection in your home you pay the cable company, the cost of the router and the electricity to make it work 24/7. And this is just enough for one family and within 20 feet of radius. An airport definitively needs more, so why Google is so happy to offer you that for free?
And what about GMail? It is a wonderful free product and you have 8Gb of space for your emails. On the other hand, buying 8Gb of memory card for your camera arts you back of $20.
Google Chrome is a great browser but why would Google invest the salary of 50 of its own engineers to develop a free browser while there are already plenty of alternatives out there? Why Yahoo would develop a special toolbar to put in your browser while there is already a search box on the top right corner of it?
There are lots of other examples like those on the web. Almost all free software (e.g., if you installed uTorrent it came with Ask.com toolbar) on the Internet comes with a toolbar nowadays.
The answer is simple: they want your data.
Those companies are not looking for your address or SSN. They are interested in your hobbies, the news you like, which pages you visit, and what you buy. They are trying to create a profile of you and then use it to provide better targeted ADs, increasing the likely-hood that you will click on them and therefor make them money.
Clicks and time spent on each page can also help web search engines to improve and train their ranking algorithms. If everybody stop a 5-minute YouTube video after a couple of minutes, it is probably not that great. The same goes for a page full of text abandoned after a few seconds. On the other hand, if the average time spent on a page is 3 minutes, and you spend there only one, it is probably just not that relevant to you.
GMail is a great example of this technology. While you read your email, perhaps discussing the recent vacation of your pal in Hawaii, the servers of Google are busy at work extracting the important keywords from those messages and providing you flight and vacations offer on the right side of the screen.
The free WiFi that Google offered around the Christmas holidays allowed them to gather plenty of data on what people were buying this season, information that could then be used to improve Google Checkout. At the same time, they could monitor in real-time which news people were looking at, which definitively helped improve Google News.
Should you stop using all those products? You cannot, we both know it. However, you can take steps to reduce your exposure: delete all the browser toolbars (what do you use them for, anyway?), start using a free browser like Firefox, and install extensions like CookieSafe and Adblock Plus.
Prostheses Technology, the amazing progresses of last years
Losing my eyesight, my legs or arms has always been among my biggest fears.
I would love to be able to do research 24/7 in all the possible fields and help to improve the life of the less fortunates, but my knowledge in the medical field is very limited for now and I still have to finish my PhD in Computer Science before jumping into something else.
Luckily, other people are doing that and their progresses blew my mind. If you did not do that already, go read the article “Bionic Legs, i-Limbs, and Other Super Human Prostheses You’ll Envy” in this months’ Fast Company. Its amazing to see the progresses in Prostheses Technology of the last years.
Computer research is fun, but this is totally another level. Go guys, you are the real heros.
Search Results: 65% of Users’ Attention goes on First Three
According to a 2004 eye/click tracking study (Eye-tracking analysis of user behavior in WWW search) done at Cornell University on Google results page, users spend about 50% of the time on the page reading the snippet of the first and second results, and 14% to read the third one.
Here is the percentage of time spent reading the snippets compared to the percentage of clicks done on the results.
eye clicks
1 28.43% 56.36%
2 25.08% 13.45%
3 14.72% 9.82%
4 8.70% 4.00%
5 6.02% 4.73%
6 4.01% 3.27%
7 3.01% 0.36%
8 3.68% 2.91%
9 3.01% 1.45%
10 2.34% 2.55%
The eye-tracking data can be especially useful for who is trying to train a relevance/ranking system and uses Discounted Cumulative Gain as metric.
Make your Wii play DVD and Nintendo Games
According to some statistics the large majority of Wii’s bought stop being used after about 6 months. Nintendo’s own statistics reveal that the revolutionary Wii Fit is used on average only 4 times by each customer. Pretty lame.
But I can understand them: at first, you love the games and the innovative controller, but then you realize that you are not actually doing much in the games (did you ever try to play Wii Tennis?) and that you are not much into them either.
So, what else can this machine do? Play DVD and old Super Nintendo Games (SNES) to start with. Carve 30 minutes our of your next weekend, find a SD card reader and follow the following pointers.
First of, you want to install Wii Homebrew Channel. It’s fairly easy using Bannerbomb, just make sure you use the right version for your machine.
To make it play DVDs you likely need to install a patched cIOS. You can do it offline or online, depending if you have an Internet connection. Then install MPlayer CE.
To have fun with old Super Nintendo Games install SNES9x GX. Its interface is really nicely done and the games play smooth. My favorites are: Bust-A-Move, Earthworm Jim, Micro Machines 2, Pinball Dreams, Sonic the Hedgehog, Street Fighter II, Super Mario Kart, Super Mario World, Super Tennis.
I find these old games so much better than those new 3D digital games which kids play nowadays.
