I recently embarked on a coffee-related project. The end product of the project is not completely defined, but it involves visiting cafes all over the world, studying the variations in coffee customs and preparations, and, of course, spreading the word about macchiatones world-wide.
As a first step, I've created a web site that lists my favorite cafes. These are cafes I visited recently, so the list is still short, but I'm hoping to expand it over time. There are multiple criteria for being included in the list, including having good coffee (duh!), having a charming atmosphere and possibly a good location. Basically, it needs to be a place worth spending time at. I'm happy to hear suggestions for additional cafes and I'll find a way to share those with the world.

The Mumbai Attacks
Pandu wrote a nice post on the Mumbai attacks with a very personal account. Pandu grew up in precisely the area where the attacks took place and knows quite a few people who were affected in various ways.

A Week in Macchiatone-Land
Oriana and I just came back from a trip to northern Italy where we visited Padova, Trento, Venice and Verona. I'm, of course, not qualified as a writer to appropriately describe the Italian experience, so I'll stick to what I know. Some pictures can be found here.
The reason we went to Italy was to visit the University of Trento, where I was recently asked to serve on the advisory committee of the computer science department. It's quite an impressive place! In about 7 years they built a Ph.D. program from scratch and it now has about 200 students. They've also hired quite a few excellent young faculty. They are able to attract students from all over the world (the courses are in English) and it's a very dynamic place. They also have quite a bit of interaction with local industry. If you're looking for a place to do a Ph.D. (and have great coffee in the meantime), this is a great place.
Which brings me to the second topic. Northern Italy is the mecca for my favorite drink, the macchiatone. Whereas in other places in the world I typically need to explain the concept and get a bad approximation of the real thing, in northern Italy you can walk into any cafe and get a great macchiatone. We even visited the original Caffe Del Doge in Venice (and I'm still recovering from the 5.50 euros for that macchiatone). Later I found out that if you drink your coffee standing, then in most places it will cost a mere 90 euro cents! The official explanation I got for this phenomenon is that in Italy coffee represents a short, intense emotion. This trip has given me quite a bit of material for my coffee project (but I'll explain that elsewhere).
Finally, social networks are really cool when you travel. I was able to collect good recommendations on what to do and where to eat through Facebook (thanks, Andrea!). I enjoyed the comments I got on my status messages and uploaded photos during the trip.

A Tour of South Tel-Aviv
I recently came back from a trip to Israel to visit my parents. One of the highlights of the trip was the tour that my dad gave me of south Tel-Aviv. For many years, the south part of Tel-Aviv was not considered a great area by any stretch of the imagination, but in the last decade or so it has been significantly beautified and is now one of the more chic parts of the city. You can see all the pictures here.
My dad grew up in that part of town, so it was a great treat to follow him for 4 hours as he was pointing out the various landmarks, and moving about with the familiarity that only a teenager has with his neighborhood (albeit over 60 years later).
The tour started around the corner from the apartment his family rented when they first immigrated from Greece to Tel-Aviv. We then went to what used to be the Alliance School, where my dad went to elementary and middle school, across the yard from the girl's school. In later years, the two schools became meeting points for young activists of the rival underground movements in the pre-state days (the Haganah and the Etzel). Now it is the Suzan Dalal theatre.
We then walked through the Neve Tzedek neighborhood with its charming houses and some Bauhaus-style architecture. We got onto Rotchield Avenue, where the rich people used to live (it's not that much cheaper today either). One of the houses there was where Ben Gurion declared Israeli independence in 1948.
We walked through Herzl St. where my grandfather owned a little store, the big Sephardic synagogue where my two aunts and uncle married and paid a quick visit to my dad's highschool. Finally, we got to the very happening Sheinkin St with its cafes and shops. There we looked for a high-school friend of my dad who had a pharmacy there for 50 years, but apparently retired recently (and by chatting with another pharmacist my dad found out things about his friend that he never knew).
We then sat in a cafe for a bit, and that's where I juxtaposed the present with the past. We got the waitress to take a picture of us with my blackberry and then I showed my dad how I'm instantly sharing it with 200 of my best friends on Facebook. Finally, we walked through the Levinsky Market and spent a bunch of money in a deli before heading home for friday lunch.
A few days later I found myself spending a few hours in Prague. Here are some pictures. Clearly, this was just a teaser and I need to go back.

The Claremont Report on Database Research
Once every 5 years, a small group of database researchers, practitioners and opinionated professionals get together to assess the state of field. The report written after the workshop represents the consensus on new research areas and describes some of the discussions that took place. The goal of the report is to foster more discussion in the field, so please go ahead and discuss!
You can find the report here.

OpenII: Open Source Information Integration Suite
Last week I hosted the OpenII kickoff workshop at Google. We had representatives from several companies: IBM, Microsoft, Yahoo, MITRE, Google, one guy who was supposed to represent Oracle but decided to be a professor again, and a couple of professors.
The goal of OpenII, as the name implies, is to create an open-source set of tools for information integration. The tool set will include, among others, wrappers for common data sources, tools for creating matches and mappings between disparate schemas, a tool for searching a collection of schemas, and run-time tools for processing queries over heterogeneous data sets.
The main goal of the effort is to foster innovation in the field of information integration and create tools that are usable for a wide range of applications.
In research, we often innovate on a specific aspect of information integration, but then spend much our time building (and rebuilding) other components that we need in order to validate our contributions. Having a set of open-source tools will enable us to focus on our innovations and perform more meaningful comparisons between our methods.
On the applications side, information integration comes in many flavors, and therefore it is hard for commercial products to serve all the needs. Our goal is to create tools that can be applied in a variety of architectural contexts (e.g., materializing all the data in one repository vs. leaving the data in the sources and accessing it only at query time). In addition, many of the tools (e.g., schema matchers or dedup engines) often need to be extended for the particular domain in hand to fully leverage domain knowledge. Open source tools allow application developers to do exactly that.
You'll be hearing more about this project as we make progress. If you would like to contribute to it, please contact me!

Brain Rules and Computer Science Education
I just finished reading Brain Rules by John Medina. The last page of the book inspired this post, but let me first tell you what the book is about.
The book examines different aspects of our brain and derives from them some principles and suggestions on how to improve better behaviors. None of these suggested behaviors are surprising at all, but Medina (very entertainingly) explains why they are good for us given the brain's structure and describes some research that validates these claims. For example, chapter 1 tells you that doing aerobic exercise actually improves your mental capacities. Another chapter talks about the need for sleep and another on why stress is bad. Two chapters talk about memory (short term and long term), explaining why repetition of new knowledge can greatly improve its recall. Another chapter explains (finally!) that men and women are different (women are apparently much more complex than men, in case you need another shocker), and another stresses that we never stop learning in life (or at least, we have the capacity to).
At the end of every chapter, Medina asks how we can apply these nuggets of knowledge to develop new methods for education. In the last chapter, he explains why the unique aspect of medical schools make for well-trained doctors as well as curious researchers. The point is that in medical school students are learning the theory of medicine at the same time they are practicing it (in increasing doses as they advance in the program). Hence, they are able to apply their knowledge immediately and, after observing patients, ask novel questions that lead to new research and discoveries. Medina suggests that the same principle can be possibly applied in other disciplines.
I think Computer Science education can really benefit from such a model. I obviously don't have all the details worked out here, but imagine that every Computer Science department (or set of departments) had a software company on the side. As students go through the program, they start getting tasks from that company to build software for it, participate in designs, see how product decisions affect engineering processes, and even see some company politics at work. These companies will be real (they'll need to pay for these services) -- they'll generate real software for real customers.
I even have an initial idea of what these companies can do. Given that these companies are likely to have challenges competing in the market, they need to address a niche of customers who are willing to put up with lousy service, mediocre products and delays in software release cycles. I.e., customers who have nowhere else to go!
These customers are called scientists. Scientists are always complaining that they don't have the right software tools to do their science. Real companies typically don't find scientists to be an appealing set of customers because, well, they don't really want to pay up and they often have very specialized needs. There are huge challenges in creating good software tools for scientists, and university-affiliated companies could be an excellent place to develop this software, while preparing the next generation of computer scientists for the real world.
