Weekly senses exercise

Reading a so so article about brain improvement and the excellent book “The Man Who Mistook His Wife for a Hat“, I mixed up some ideas, until arrived to this one: try to focus on only one sense each day of the week. Of course you always have all senses in “active” mode, but the idea is to spend some minutes feeling “twice” with one of them, noticing the details it gives you: patterns, contrasts, sensations, etc.

Mon – Propioception
Tue – Touch
Wed – Balance
Thu – Vision
Fri – Smell
Sat – Taste
Sun – Hearing

Isn’t this a good idea?

New DIY Greenhouse

New DIY Greenhouse
Here you have my new super-greenhouse!

Material needed:
– 130x90cm 5mm glass
– 2.5m wood stick (x2)
– 2x1m polystyrene-glass surface
– 100ml of water resistant paint

Lessons learned:
– Julio, stop thinking about building things!
– Pine tree wood is not convenient for outdoor, despite is the cheapest wood. They say teakwood is perfect (or other wood from wet jungle trees). Anyway, I made it with the first one, and painted it with a special water resistant paint.
– Cutting real glass is not as easy as you see in youtube videos. First I tried to cut glass to make the wall, but the result was quite ugly. So then I bought plastic glass (2x1m for 40€, cheaper than real glass).
– In order to cut polystyrene-glass you need to adjust your electric saw at top speed. At low speed the fiber starts to oscillate and breaks easily. At high speed the cut is sealed after the saw moves on, due to the heat!, but later you can hit the join and split the parts.

By the way, compare it with my last year prehistoric balcony greenhouse.

FriendFeed first impressions

NOTICE: Find more in my tech blog:

In my previous post I criticized Facebook (“Fb”) quite a lot. But at the end it does some good stuff, like the “keep in touch with your people” thing, a decent content aggregator and a way to publish (or share) things like personal mood or thoughts, links, images, etc. But if you distill some of these good parts of Facebook, and improve them, you get FriendFeed (“ff”).

FriendFeed is a content aggregator which is far more complete than the one in Facebook (compare just the numbers: on Fb there are 13 possible sources to aggregate from, and 57 in ff). Actually Fb aggregator is quite bad, because some sources are not updated, and you need a 3rd part app to do so. ff has also a way to share links, images and such, and it’s really impressive (just add its Bookmarklet in your bookmarks bar and see its power). Moreover you get the usual “publish what are you doing”, “like it” and “make a comment” actions.

But the most pleasant thing I found is that it is a real Web 2.0 site. You add content, everybody see it, and there is RSS. Try to search for RSS in Facebook, find nothing. You can even get a widget (as you see on the right column, if you are visiting The groups (called “rooms”) are meaningfulness, with current people interested in the subject of the room.

Anyway there are 2 things that I miss from Fb that I’d like to see in ff. First is “events”, a way to invite people to an event and mark dates (despite there are complete websites that do just so). Second is “amount of people”… but this is a question of time: first time I entered in Facebook nobody was there, a year later a lot of people signed up. Let’s hope same thing will happen in FriendFeed.

So, see you there.

Facebook, or waste your time channel surfing

NOTICE: Find more in my tech blog:

Have you ever feel how fast the time goes by when you do some channel surfing on TV? “I spend 2 hours in front of the TV, changing from one channel to another, and finally I’ve not seen anything at all”. I had this thought of “wasted time” while surfing on Facebook recently.

Fb, the origins
I logged in on Facebook some months ago, but I didn’t understand the meaning of the website at first. I came from social websites that focus on one thing, like Flickr (pictures) or (music listened), so it was a bit weird to see a social website which end is the social relation itself, without a “theme”. Moreover the only friends you are supposed to have there (and to let them see your profile) are just the friends you currently have in Real Life, so basically Facebook aims to be a copy of Real Life society. So don’t expect new friends, just expect to see what your current Real Life friends are doing… but basically you can do so with other methods, like IM. I mean, when I use Internet, I don’t expect to see a mirror of Real Life, I expect to see different things, improved things… or just surf Wikipedia.

Fb, closed to foreigners
Another surprising thing is that your profile is private, a random net user can’t see it, unless he is your friend. This “closed” philosophy as default annoyed me. It could make sense, to keep your data from public. But coming from websites where you add content, mostly public (like photos in Flickr), and let the world see your stuff, this philosophy is at least paranoiac. Of course you can mark pictures as private in Flickr, and you can open your Facebook profile to everybody, but how many people do so? How many know how to do so? The default settings are the ones that show the website philosophy.

Fb, the false sense of security
Despite it claims for keeping your stuff away from foreign eyes, there are a lot of back-doors to overpass the private settings. The easiest one is just see Mr.X friends list, and look for one with open/visible profile, let’s say Ms.Y… then you can see pictures tagged with Ms. Y, even from the Mr.X picture sets… finally you get full access to Mr.X pictures. Another way is creating an application, using Facebook API: when somebody uses your fancy app, you can get FULL access to all his data, and can (for example) save it in your personal server. So you only need to create a small test app (“How freak are you?”) to harvest a lot of private data.

Fb, trying to create content
Of course in a social website without theme there will be less content created, and user will come back less often. Therefore Facebook staff have to help people to produce content, in order to induce other people to revisite the web often. One way is acting as an “aggregator” (gets content from other web2.0 places, like Flickr or, and publish again in user’s page). Other is creating an API to create applications. 3rd part developers come to create apps, salivating by the amount of possible users for their apps, and Facebook is happy to see more stuff in his system. I created a couple of Facebook apps and I can claim that their API is a torture. Basically they don’t let you use libraries, like jQuery, so you are forced to write old style code. Later you discover you can ignore it and create an iframe for your app… so that means your app is not a real Facebook app, just a nice Facebook frame that borders you website in your personal server.

Fb, a waste of time
So, I can guess that the 80~90% of produced or pseudo-produced content in your profile (or friends profile) is low quality. Do you really need to know that your old friend from school Harry loves chocolate? Nah!

Of course Facebook has good things: the content aggregator and a way to publish things neither short nor long in a fast way… but for such things you can use a better website, like Friendfeed.

Time of changes

The economic meltdown seems to encourage new ideas to blossom up, making classical product borders less noticeable. I’m focusing on hardware technological products today, but this probably applies to all kind of products, even financial ones.

I’m going to show you a couple of interesting examples I saw in the last few days:
Open Pandora, “Handheld Linux Console” : Some years ago somebody had the brilliant idea of creating a really small laptop, without a real old-style hard disk, and called it “net-books” (referring to notebooks + net support). Then we had PDA, net-books, and normal laptops. My small laptop (12″ screen) is still a laptop, but when I bought a Nokia 770 (theorically “Internet Tablet”, actually a PDA with Linux) it was just difficult to answer “what is it?” to not tech people. And now I’ve fallen in love with this “strong-PDA-like with keyboard in a Nintendo-DS structure made for playing games but which actually is a complete net-book with Linux”. Damn, I’ll need to memorize this description.
OP-1 synthesizer and controller : In the old times, you hadn’t a lot of options to look for when thinking about creating electronic music. Basically a synthesizer. Then Yamaha created the TenoriOn. And now I stared my eyes on this toy synthesizer, with FM radio and sequencer, created by designers. I can’t set a category for this, except the obvious “I Want One”.

Moreover one detail to think about this products is that there isn’t a big traditional company behind them. A synthesizer created by a group of designers? Sounds weird, but those mixes of disciplines are the future. Also it’s interesting to read about OpenPandora history. A guy annoyed with a Korean idea, another guy, Texas Instruments looking for a machine to test its new chip…
