What’s your thought about the raise of Android compared to the iPhone? They now sell 200K devices a day.

As a user, and as a developer? My feeling is users buying iPhones are more willing to buy applications on the appstore than Android users, which only buy… a phone. But I may be wrong.

As a user, I like the fact I’m connected all the time to IM like gtalk.

I’m now part of Causes which already has nice success stories, but what is Causes?

Causes was founded on the belief that in a healthy society, anyone can participate in change by informing and inspiring others. The most successful movements have always been born out of and held together by the bonds of real world relationships, and online social networks present never before seen opportunities for organizing. We strive to build tools for people to mobilize their friends for collective action, spread the word to friends of friends and acquaintances, and eventually launch movements that span local communities or even the globe.

Causes is also one of the largest current website using Ruby on Rails, and is recruiting developers. So get in touch with me if you’re looking and feel like a Rails hacker, and feel free to follow @caretopia.

TweetSell.it allows you to see what’s being sold on Twitter, in real-time. You can also see what’s being sold near you, or search for specific items like the iPhone4. I’ve had the idea for a long time, but I only released the service a few days ago.

What do you think? How do you like it? What should be included? Let me know here or through my twitter @fabienpenso. There are more features to come later like online payment.

I had developed an iPhone application for the VU’ Agency, and it’s finally live on the AppStore. It’s available in French and English, and include more than 600 stories from the VU’ Agency. If you like photography or work as a photographer, this is probably a must have.

After a few months of hard work, the new version of my push notification application is finally available for your iPhones and iPads (it supports multiple devices and synchronize content between them). I’m really looking for feedback for this application, so feel free to contact me if you have feature requests. You can get it at http://2apn.com.

It allows you to receive real-time informations from RSS feeds, Twitter, Email, has an API to use to push to you directly. You can then share content through Facebook/Twitter, Email. There are favorites, thread support, and so on.

Just subscribed to the Chirp Twitter conference even I’m not 100% sure I’ll show up. If you want to meet me, feel free to let me know by email or Twitter.

Do you like Paris? Do you want to visit Paris like a French without visiting Paris? Why don’t you take a look at our application UrbanTrip.

It includes French and English very high quality content. Not taken from Wikipedia (which is good), but handmade specifically for the iPhone display. And yes, it will work with no network so you can use it anytime you’re visiting Paris for real. You can save favorites, view pictures and use geolocation to find the spots.

You also have all the pricing, opening hours and so one. Try it out !

I’m working on a service using the streaming API from Twitter, a great feature as it gives you instant access to Tweets. But then you get overloaded by Tweets, and because I’m looking for Tweets talking about money, I get lots of noise.

Looking at TwitBlock, I filtered out lots of it :

1. Ignore tweets from recent users (if created less than 24 hours ago)
2. Ignore tweets from users with default profile image
3. Ignore if fewer than 10 followers
4. Ignore if user description and name are blank
5. Ignore if followers fewer than 100, and friends count is > (2*followers_count)
6. Ignore if followers count over 100, and friends count is > (5*followers_count)
7. Ignore if the user sends more than 20 tweets per day in average, since its creation

Some of these is working for me, but might not work for you at all. However, I think there could be a better way for a mass use. I ran mail servers for years, a very reliable way to handle this is to use DNSBL (also called RBL). You could have different RBLs for different use, and any twitter client could implement this very easily. Please note this could probably not work for Direct Messages except if Twitter grant specific access to the service, which they would probably never will.

Just released http://gemcutter.org/gems/penso-feedbag to discover feeds for specific website, with proper charset, a fork from muck-feedbag, which was a fork from feedbag.

Yes, I love Ruby, Git, Gem and GitHub.

>> require 'feedbag'
>> Feedbag.find("http://lemonde.fr")[3]

Ça fait des années que j’entends dire qu’il faudrait que je passe aux disques SSD. C’est fait pour mon MacPro avec l’achat d’un SSD Intel X25-M v2. Le résultat ?

Le temps de boot passe de 76 secondes à 26 secondes. Le lancement de Firefox avec pleins d’onglets de 12 secondes à 3 ou 4 secondes, le lancement de Safari passe à moins de une seconde.

Rapide quoi…
