Stellarium, the sky inside your computer


Two new versions in just a few days: I’m talking about the popular software named Stellarium , which lets you explore the heavens, taking advantage of a large database that includes more than 600,000 stars (with extra catalogs of more than 120 million items!), with the representation of the constellations, images of nebulae (full Messier catalog), realistic representation of the Milky Way, planets and satellites. Stellarium also includes realistic effects of sunrise and sunset, zoom controls telescope, and much more … 


…  Briefly, there are so many interesting features that even those vaguely fond of astronomy can be convinced to try it!

Version 0.10.3 has been released on 29 of January, with new features like plugins that allow to predict the position of artificial satellites, and a database with constellation for twelve different cultures.. and many other thinks that you’ll be glad to discover by yourself šŸ˜‰


Version 0.10.5 has been released just some days ago; it features the correction of a lot of bugs, a reduced loading time and other improvements.
Stellarium is available for all the major operating systems (Windows, Linux and Mac OS X), it’s free and open source. Binary packages for Ubuntu 10.04 are now also available from their website. Could you ask for more…?

Ubuntu 10.04, my two cents…


Originally uploaded by mcastellani

Some days ago, I upgraded my linux box to Ubuntu 10.04. I am pleased to say that the upgrade took place without worries and virtually no intervention on my side (aside a couple of request from the upgrade script in order to ask permission to overwrite some system files).
Now, detailed descriptions of the new release may be easily found in the network (you just need to google a bit to find plenty of them), so here I note only some impressions of use. Say, what strikes me without “scratching” too much under the surface, in the first approach. 
    Let’s see …

  • for a “sick” of social networks like myself, Ubuntu 10.04 comes with a really interesting aspect: it is eminently social. It comes with the client gwibber (now at release 2.30.0.1) that supports Twitter, StatusNet, Facebook, Identi.ca, Digg, FriendFeed, and also Qaiku (a microblog service with an exciting support for languages; I like it a lot and, as a matter of fact, I have realized most of the interface translation in Italian). To tell the truth, not only it’s included, but it result deeply integrated in the “social” concept of Ubuntu, for which we can now express our “online presence” directly from the top status bar of Gnome. I am very curious (and so are the developers) to understand whether the inclusion of native Qaiku in Ubuntu will bring more users to put their noses in this interesting but still little known platform.
  • There was much discussion on Ubuntu related sites, concerning the new network online music store that comes integrated into Rhytmbox, the “software and music playback for GNOME”, which is now reached its version 0.12.8 (but what to say about this habit of going forward with the zero point something ?). I just spent a bit of time in it, and I found that the prices of a number of albums are very interesting and – at least in some cases – significantly lower than their  iTunes counterparts .
  • The GNOME desktop backgrounds have my appreciation, for the aesthetic work that I think has given excellent results. Overall, it seems quite clear that Mac OS X has been well taken into account by the Ubuntu developers (up to small details as the discussed choice of putting the icons on the left side of windows) … but that’s OK, no problem;)
  • Even the ‘Ubuntu Software Center’ (again, the not-too-hidden reference not is to the online software repository of Mac OS X) has made significant progress. Browsing through categories to choose the software to install it ‘s now easier, and it is a truly enjoyable experience … and it’s free, too!

Overhall, I like Ubuntu 10.04. Surely there are things to improve and fix (for example, during the first days of use I stumbled upon some oddity of gwibber, which kept to give me authentication error in Qaiku, despite having already added the correct API at least a couple of times …), anyway I think we came to a really respectable version. One of the most important representations – perhaps the most important at present – of an open source operating system. 
… what do you think, I’m exaggerating?

Twitter Blog: Hello World

We hope you’ll share in our enthusiasm as today we unveil a simple service we’re calling Promoted Tweets. It’s non-traditional, it’s easy, and it makes a ton of sense for Twitter.

Twitter makes its first moves toward advertising. Personally, I do appreciate the honesty and transparency that comes out from the blog post. Anyway, I wonder what will be the response of the community…

A guest post by Flavio Castellani
We all hate Microsoft for its amount of money making, its weight in the consumer market and for much more.
And we all love Google, for its fresh spirit, its apparent disinterested way of adding value to our technological experience and, ultimately, to our lives.
And yet, Google is arguably going to make much more money than the evil Microsoft. It’s already controlling (as a monopoly) the Internet business on a scale beyond imagination. You don’t hear about microsoft interacting with nations and government legislative organs, like google does for clearing the path to its operations. You don’t hear (yet) glamorous cases of antitrust sentences turned bad against google.
The most important thing: Microsoft gained our hate for the way their products made us feel, and for the control on what we use to surf the net.
But while we recognized and reproached Microsoft for their attempt in controlling the browser we use to surf, google increases its control on the content of it. Every day, we let increases its control and dictate more and more not just the experience on how we access the information, but the accessibility to the very information itself.
Do we think that the free gadgets and applications are really for free?
this is like believing that the free drinks in las Vegas are really for free.
Google now has tentacles in mobile networks and operators, fiber optic network and ISP providing, Internet, mobile devices and expanding.
There is something confusing about so many free applications and services, and yet a stellar share value trend in the stock market exchange.
The way I see is this: to run a business you need to have
  • an investment,
  • some assets,
  • products to sell, and
  • customers to sell them to.

This is the archetype of business. Is the minimum denominator any business have in common, and upon which they are based on.
How does it map to Google way of making money then?
  • Their protocols and their applications are not their products, those are their investments.
  • We are not their customers. We are their assets.
  • Data-mining, eyeball time, internet syndication: those are their products, the ones that they sell to increase their stellar share value and their business. Data-mining in particular is one of the most sought and profitable products to sell.

For MS office the revenue stream is the classic one and much simpler:
  • their applications are the products, the one that they sell, and
  • we are their customers (in the specific case of MS office business model, of course)

Google is not a bad thing. It’s just a huge thing now. And huge corporations relentlessly pursue the increase of their shares value in the stock market.
Above a certain critical point, the direction of a corporation drift to whatever direction satisfies its goals.

Google contribution to civilization (I’d adventure to say) is remarkable. But it’s clear that this contribution is not its goal, is its mean to get to its goals. its goal is profit ($$$) from internet advertisement. That is what pays the freebies, and the immense funding in R&D to expand in mobile, voice, ultra-fast fiber ISP, video, authoring and whatnot.
Until its means and its goals matches with our interest, that’s great. But we need to be careful to see well all the parameters of the equation.
Google strives to position itself more and more as the internet content syndication provider for the general population. That takes away the beauty of the internet, and more sadly, diminishes its distinguished characteristic that opposes it to television.
Internet is truly the most significant informational achievement in the past 100 years. We must fear any monolithic entity that seek control over it, for lucrative scopes. My believe is that Internet is a solid answer to the past decades of the informational unbalanced entry point created with the advent of television, which generated a chain of consequences that lead to a corrosion of the democratic political debates and to an increase of influence of corporations in the nations public and political matters.
Internet could bring a ribalancing and galvanize the spirit of the debates. Its general access point for content authoring enable it to be the future arena where ideas can truly democratically compete, assuming they remain equally accessible.

Amarok “Clear Light” released

Amarok is definitely a great player for linux. This wonderful software just reached version 2.3.0, code-named Clear Light (which, being a fan of Mike Oldfield, makes me immediately think of this music, like Amarok that obviously makes me think of this wonderful disc. ..).

Anyway, at the risk of alienating a good portion of my (limited) audience, I’d venture to say (also following a commentary that appear belows the video presentation on Youtube) that Amarok is perhaps not yet at the level of competing on equal terms with well known player for other operating systems such as iTunes.

That said, it also worth to say that it is still a complete and rather powerful software: certainly for KDE users it represents  a great and rewarding choice, that can contribute greatly in making the desktop environment more comfortable, also in terms of management of a user’s collection of audio files (as well as Internet radio and podcasts, which in passing is a recently reinforced section)


The video itself is quite pretty and the accompaining music is itself really enjoyable .. which is surely a good think, for a multimedia player presentation! šŸ˜‰
