In the last couple of years, some technology advancement have quietly entered mainstream coverage and even when their short term applications are obvious, their long term impact is still to be unveiled. They have the potential to change the technology industry landscape and create a new industrial revolution.
3D printing is the technology to create 3d objects by depositing droplets of plastic layer by layer, much like a conventional ink injection printer prints a picture. This kind of printers (or fabs) have been used in the industry to create prototypes for long time, but now are becoming accessible to mass markets, with even open source projects like fab@home pretending to put a fab on every desktop. As I have already commented, the potential impact of this technology in the consumer electronics market is enormous. Just imagine that you could download and "print" a replacement for a plastic piece, a new ceramics design or even a jewelry design.
Printable electronics are digital circuits created by laying out conductor materials over a polymer surface using a traditional printing technology. To date its biggest issue is the relatively slow clock speeds that they can use. However, recent discoveries may change that. Diverse printed electronic devices like non-volatile RAM, RFID tags and TFT displays were recently showcased in the Printable Electronics conference what seams to indicate that the technology is ready for simple devices like sensors and "smart" materials.
Printable batteries follow the same principles of printable electronics, but with the objective of store and later provide electric power. One example of this technology is Power Paper which provides 1.5 volts batteries. And interestingly, such batteries could be combines with printable solar cells to obtain self-powered devices that don't require chargers.
When considered together, these technologies will give us the license to print our own gadgets. This will surely boost the innovation in devices, as designers won't have to go through long and expensive design-prototype-production cycles, nor will they need to reach critical mass to be cost/effective.
Obviously, having a high quality fab at home capable of printing complex electronics probably won't be affordable in a decade or more, but the deman for such custom made electronics will boost a market of electronics print shops, where you can go and print your designs.
Big consumer electronics producers like Sony and Samsung will need to reconsider its role and become designers - instead of manufactures - of certain product categories (I'm not talking about printing the next Play Station at home) .
This will be begining of the much aticipated era of massive pesonalization, but without intermediaries.

The "poor man's" semantic web
From its very beginning, the quest for smart queries over that vasts amount of unstructured data we call the the Web has been a very elusive endeavor, yet one of the greatest importance.
The problem is that the Web has developed mostly as a medium of unstructured documents for people rather than of information that can be manipulated automatically.
The very creator of the web as we know, Tim Berners-Lee, has largely discussed this limitation and has also proposed a solution: the Semantic Web. The main idea is augmenting Web pages with hyperlinks to definitions of key terms and rules for reasoning about them logically. This meta data is targeted at computers and the resulting infrastructure will allow complex knowledge intensive tasks such as highly functional personal agents.
But this idea has not yet taken off. The main reason is that adding such metadata results cumbersome to the persons who creates the pages. It is not natural in the context of the content creation, at least not beyond the simple tagging or categorization of pages.
But more importantly, do we really need such intelligent web?
Let's consider how Google works. its tremendous success of Google comes, to a great extend, to simple yet powerful idea: use the implicit knowledge that exists in the web. Google search algorithm not only use the content of a page but also consider the key words used in the hyperlinks that point to that page. This is basically a sort of poor man's semantic annotation, well if you can call Google poor.
Now, if you have, as Google does, access to billions of pages and hundreds of thousands of processors to mine it, can't you arrive to the same "intelligent" answers to questions as with a answer engine? I guess that the result would be difficult to differentiate. To start with, if a question worth to be asked (and very likely, even if not), surely someone already put the answer in a web page. Consider this question from Wolfram's web page "What is the 307th digit of Pi?". A quick search on Google retrieves as the first this page on which you can search for any digit of pi.
Paraphrasing what Gary Kasparov famously said after been defeated by Deep Blue: "quantity can become quality", meaning that a brute force approach, given enough resources can actually achieve results that are indistinguishable for actual intelligence.
Update: It is clear that the guys at Google Research share this view: The Unreasonable Effectiveness of Data.
Update: Tim O'Reilly on the difference between Semantinc web and pattern recognition approaches

More recently, another even more radical approach has emerged: the answer engines. In this case the goal is not only to enrich the content with semantic, but to produce pure knowledge content like complex conceptual maps, basic facts and inference rules to allow answering question by computing results instead of just searching for already existing documents that contain the desired information. Two example of this approach are True Knowledge and Wolfram.

Can Erlang become the next Java?
Erlang is a functional programming language that has been steadily gaining attention in the industry. Some even advocate it as "the next java", but can this actually happen? Can a single language attract enough support to become a de facto standard?
In face of the current fragmentation of the programming languages landscape (Ruby, Python, F#, Scala, and a long etcetera) this seams very unlikely at first. However, the very existence of such fragmentation is indicative of the search for new programming paradigms to tackle the needs of now day's applications.
Java success in the early web days was due, mostly because it offered two key features that where essential for the nascent web applications: dynamic code loading from the network and platform independence. From this point its acceptance grew dramatically in both desktop and server applications, despite the criticisms for its poor performance.
Similarly, Erlang offers several key characteristics for the next generation of distributed applications:
If recent history with Java is indicative, Erlang has all the credits to take off as a main stream (if not dominant) programming language for next generation web applications.

Similarly, Erlang offers several key characteristics for the next generation of distributed applications:
- Its adequacy to parallel and distributed programming thanks to its simple message based concurrency model.
- It allows the hot swap of code (code of running process can be change while they are still running!)
- It has also the reputation of being rock solid, running on Ericsson's ATM Switches with a reliability of 99.9999999% (that is some 30 seconds of downtime a year!).

Why Google should be worried about twitter?
It is rather uncommon to see a Google's officer to attack competitors, but this is exactly what Eric Schmidt, Google's CEO did. An he did in a rather surprising way: calling twitter it "a poor man's email system" because it lacks all the basic capabilities of a full flagged email like gmail. It is unconceivable that he mistakes Twitter with an email. What he did was just spread some FUD about Twitter. But why Google, with above the 100 million email accounts even bothers to acknowledge the existence of Twitter, with its modest 5 millions users?
In this declining economy inversion in advertising is decreasing and advertisers are looking for better channels. Twitter has demonstrated that it can be used in very innovative ways for marketing. For viral campaigns, for personalized advertising, for brand creation, to receive user feed back. And at least by know, the price is quite low: free!
Also, Twitter users seams to handle commercial messages rather well, maybe because they are easily integrated in the message flow and also conveniently filtered, searched, aggregated, etc. More over, advertisers use Twitter as a truly bidirectional channel not only to advertisers,but also to gather feedback.
It is expected that if Twitter wants to continue in business, it must start charging for commercial usage. It is not clear how, but there are already some interesting ideas.
Twitter has still a long path to follow before threaten Google's dominance. This wouldn't be the first time this happens. One comes easily to mind: when Google came from nowhere and displaced Yahoo. And you know, history has some tendency to repeat itself.

What does Twitter change?
The tremendous success of first the Internet and later the web, is mainly due to their main design principle: build a basic, unsophisticated, yet flexible infrastructure and let the applications on the edges put the intelligence (the so called end to end principle).
More over, the Internet/Web infrastructure is based on open standards, like TCP/IP, HTTP and HTML prevents provider lock-ins and lowering the entrance barriers to newcomers.
Such infrastructure allows an open-ended innovation, supporting application architectures and utilization patterns no one had considered when it was designed. For example, who could ever dreamed about Ajax back in the early 90' ?
Twitter follows the same principle and has therefore the same potential of the technologies it is build upon. It offers a basic infrastructure for a publish subscribe communication of short text messages, offering an open API that allows others to develop sophisticated applications like searching, aggregation (Tweetdeck) and trend analysis (hashtags.org, Twist, TweetStats).
One obvious difference is that Twitter is neither an open infrastructure nor is based on open standards -- However, neither is Google Maps and that has not prevented it to become a "de facto" standard. More over, there are other technologies like the venerable IRC and more recently XMPP that have similar capabilities for instant communication and are based on open standards, but haven't had the same impact than the web. Why should then Twitter be different?
What makes Twitter so powerful and gives its tremendous potential is how it is actually used. Users, post anything they found relevant, interesting, funny. They post about themselves, friends, hobbies, work. They expose preferences and dislikes. In other words, Twitter opens people's thoughts and feelings and make them available to others instantaneously, creating a continuous conversation on which you can enter and leave. Participate. Watch.
This is the closest we will ever be to telepathy. And that surely will change the way we communicate.

Burning Chrome (William Gibson dixit)
Google has surprised more than one, me included, releasing today its own browser Chrome. This may well be the beginning of a dramatic change of the web as we know it and nobody noticed it until the tsunami hit the web.
From what I could see in the comics style introduction of the browser's motivations and features, it seams that Google has decided to turn the browsers game inside out. They have broken almost any written rule about how to build a browser, yet it seams they were able to come with very usable and stunningly fast browser.
It is good to see that someone in the open source community finally remembers what innovation is all about and doesn't just aspire to catch someone else.
And God knows we needed such revolution badly because, let's face it, Firefox lost its mojo long ago and started to fade as a innovative browser.
If current trends continue, they will beat Firefox 2.0 launch success, even when it is currently only available for Windows (annoying, isn't it?). I just can't wait until the Linux version kicks out the door.

Shaping the future
3d printing is the technology to create 3d objects by depositing droplets of plastic layer by layer, much like a conventional ink injection printer prints a picture. Such kind of printers or fabs have been used in the industry to create prototypes of new designs.
Some time ago, the Fab@home project started to offer an open source specification of a 3d printer, which according to the project's web page, will democratize innovation allowing anyone to create and manufacture his own designs. However, the target price was still well on the thousands dollars, making this technology affordable for small shops or independent professionals, but hardly for casual users.
Now, Shapeways, a spinout of Phillips is offering the service to allow user to "submit digital designs of products that are then printed, using 3-D printers, and shipped back", "delivering the tangible object within 10 days of ordering, with prices typically between $50 and $150". This service really opens the word of 3d printing to anyone.
I can image action figure hobbyist making they own character designs and getting them printed as real objects, which then could be painted at home. Also, it will open a new opportunity for skilled designers to sell their designs of home accessories which users can print at home.
In the long term, this new technology will lead to the ultimate customization of products. For example, by allowing each one to create its own mobile phone covers: I will finally get my start trek themed phone!
And you, what will you print?
