Principles of Transaction Processing, Second Edition

I wanted to put out a brief note that the new version of Principles of Transaction Processing is hot off the presses. Simply put, this book is the standard reference for getting your brain around the transaction processing components of the IT landscape. It was the book I absorbed when I first started working on implementing transaction managers and one I turned to get up the speed on existing systems. I had a chance to review part of the book prior to publication, so I was lucky enough to get a free copy - Eric and Phil did a great job bringing the text up to date: it remains one of the handful of books that should be on the shelf of anyone involved in information systems implementation or management.

Russia and Web 2.0

Zdrasvoyteye.

When I was in Moscow last, a lot of the talk was centered around attracting foreign capital to tech investments in Russia. The pitch is - or should be - familiar: lower costs, big market, super-bright engineers and scientists. The downside is lack of transparency and a very unique business environment that is difficult (or impossible) to navigate as an outsider. Today's announcement that Facebook has taken $200 million at first looks like a kind of a reversal in this trend: tech oriented Russians still have capital to deploy and may be choosing to spend it on bargain opportunities in the US market, which remains preeminent in technology development.

A closer look, though, suggests this is a part of a trend that has been gaining steam. Russians have been developing and investing in Web technology for a long while. Yes, Google was co-founded by a Russian, but there has been a number of interesting developments based in Russia itself. The Russian firm Yandex is often described as the "Russian Google" and has picked up small Russian social networking companies like Moi Krug on the cheap (someday there long awaited IPO will happen). SUP, run by American-in-Moscow Andrew Paulson, picked up LiveJournal to support their Russian users, and now Yuri Milner's fund takes a position in Facebook. Milner is the founder of mail.ru, a former physicist, and Wharton alumn.

Watch carefully: the Russians are coming to Silicon Valley and it's been a largely under-noted trend. I've met some of these folks and they are very capable businessmen.

Events for SCA

InfoQ has a short synopsis of the event proposal that was released to add pub-sub style semantics to the SCA assembly model. The genesis of this lies in some ESB related work I had helped lead at Oracle back in the days when we first started to develop the SCA specifications - it took a long time to socialize this to the working group, but I'm very happy to see that that work has borne fruit. This fills an important gap in the specifications - previously, the wire driven semantics forced components to "externalize" pub-sub interactions in a way that was divorced from the SCA semantics - and is broadly applicable to many problem domains including Complex Event Processing, Queue/Pub-Sub style integration, and ESB scenarios.

I remain somewhat distressed over the way the channel abstraction has played out - the original idea divorced much of this from the assembly view and made it an aspect of system configuration. I think the current approach artificially mixes orthogonal aspects of the problem space. Having said that, this is a milestone for the specification and completes the basic assembly model nicely.

By the way, nice write up Boris!

Value at Risk

I'm not going to editorialize on this one: here's a layperson accessible view of the risk models that worked so remarkably poorly in the last several years.

Darwin Dissected

Though it may be impossible to miss, this year commemorates the 200th anniversary of the birth of Charles Darwin, who has justly been called the father of modern biology for this development of the theory of the evolutionary development of species. At times contentious, the fact of evolution has been long established beyond any kind of reasonable doubt - all schools of scientific knowledge are convergent in this regard. But to understand the true importance of evolution for biology as a whole, one of my favorite essays is by Theodosius Dobzhansky: "Nothing in biology makes sense except in the light of evolution."

In any case, I happen to find myself reading a facsimile of the original edition of On the Origin of Species - which I have had for many years but never read end to end. Coincidentally, the New York Times has a posted a great selection of passages by Darwin: read and enjoy.

When Finance Goes Mad

Having come uncomfortably close to working in the packaging of structured financial investments, I've been morbidly fascinated by the way in which it has led to the near-destruction of the national - if not global - economy. Here is a great article on how badly awry things went with the ratings on these instruments, and a bit of what that means for stabilizing things.

Happy New Year

I wanted to take just a moment and wish everyone a safe, happy and peaceful holiday season and new year. All the best to you and yours.

Liquidity Trap

As the fed's latest cut pushes funds target rates toward zero, I am shocked that the news is not focused on whether the US faces a liquidity trap. Instead, there is very little discussion and markets seem to be neutral on the latest news.

The article I linked here is interesting for two reasons: one, it looks into the basic issues in some depth; two, it is clear that no one really understands what is happening. Note that Bruce Bartlett is arguing that the biggest danger we face now is deflation. Maybe. But two months ago, the biggest danger we faced was inflation: the latest swings in price indices seem more related to runaway boom-bust cycles in energy and commodities - too soon to really know what we face. Time will tell, of course, but only in a backward looking sense. At that point, we'll be passed the point where we needed the information.

Gimme Shelter

Wild turkeys sensing Thanksgiving is nearly upon us gather in a safe place: my front lawn.

Budapester

After several years of delay, my wife and I finally had a chance to spend a long anticipated weekend in Budapest, Hungary. I'll give my impressions in three parts: aesthetic, economic and historical. Second - for those anticipating a visit - a few suggestions for tourists.



On several occasions, the first question I've gotten about Budapest is "what's it like?" To be frank, I've struggled to compare it to other central European cities I've visited: unlike, say, Prague, the oldest portions of Budapest are quite small: the city was the scene of many battles from the Turkish occupation through the second world war; in the latter, the Soviet army and the Nazi army clashed directly in the
city itself. With some notable exceptions, the city is redolent with 19th century facades. In fact, many of the buildings are quite impressive. My wife commented that to see Budapest, one has to be constantly looking upward.



Although it is hard to say exactly how any country is going to weather the current economic storm, Hungary has clearly experienced strong growth rates in recent years. Budapest itself reflects both a low post-Soviet starting point and the economic boom of recent years. Elegant restaurants are close to classic looking buildings suffering
from disrepair. Pricing is erratic at best. One can find a 1 USD cup of coffee, or spend 12 USD for coffee and pastry, all within a block. For a great view of the food of Hungary, traditional restaurants and the Central Market in Pest are great experiences: be prepared for tons of paprika.



A traditional breakfast at the Central Market!

The standard tourist circuit is worth doing. Budapest's museums are interesting though modest: meaning, it is possible to explore many in a day's time. There are several houses of worship that are worth visiting; in particular I recommend the Matyas Church in Old Buda and the Great Synagogue in Pest.



Matyas.

The Great Synagogue is the largest synagogue in Europe and the second largest in the world. The building is a 19th century construction and features continental Christian influence in features such as a (substantial) pipe organ: the same instrument is present in the even more beautiful Spanish Synagogue in Prague.



Time permitting, there is a modest Serbian Orthodox church on Szerb Utra ("Serb Street"), with an older iconostasis and the sweet smell of incense hanging in the air. The famous St. Stephen's cathedral is beautiful but also very modern.

And of course Budapest is famous for the public baths. We visited the baths in the central park, which is an experience not to miss. There are consultants available that will help construct a therapeutic regime while you are there, though we opted to wing it: both relaxing and revitalizing. Be forewarned: the plunge pool may not have ice crystals in the water, but it is … cold.

There are two less well-known options for visitors that I wanted to point out. First, the Terror Museum in Pest is a must-see. The Hungarians suffered under both a Nazi putsch and Soviet occupation. The Terror Museum is set in the secret police headquarters (shared by both regimes) and provides a bracing portrait of totalitarian terror as seen from the Hungarian experience. The first exhibit in the museum
was perhaps the most moving: videos of cheering and weeping crowds supporting both regimes cutting abruptly to the destruction and death concomitant with their rises. This was not an uplifting part of our visit, but a sobering and necessary look at two forms of evil.



The second thing to note about Budapest is the excellent restaurant scene. We had some of the best meals we have had in a long time in Pest. The restaurant Tigris near St. Stephen's Cathedral has fantastic food, wine and the most enthusiastic staff I've ever encountered. The "contemporary Hungarian" tasting menu at Babel was great: the chef
has a deft take on gastronomical science. Try both if you can.

The title of this post is taken from the iconic Vass shoe, the somewhat awkward looking, central European classic. The factory store is on Harris Kos in Pest and worth a visit for anyone interested in old world craftsmanship. There's a romanticism about much of Budapest tied up with the ubiquitous craftsmanship to be found.

Wild Ride

What an extraordinary few weeks we've been through economically. The economic system has started to unzip and then snap back several times: the scariest thing I saw was the more than doubling of the LIBOR rate over night. And the control of short sales is a step to nationalizing equity markets: incredible! And while, things continue to adjust and move forward, we are, for better or worse, living through an inflection point in economic history.

I was in Moscow, Russia a few weeks back when the Russian central bank had to intervene to support the ruble. At that point, cooler heads seemed to have been regaining center stage and the political climate between the US and Russia seemed to warming a bit since the Georgia conflict. Then, right before I left, a US vice president candidate speculated that we might have to go to war with Russia! A week later, the Russian markets closed for several days. I'll have a report on my Russia trip in a few days, but I'll preface it by saying it was fascinating.

I escaped the economic chatter last week by attending Oracle's Open World conference. This was by far the best Open World I have seen: customers were very enthusiastic and the show was extremely well coordinated. Getting back to core technology was a great break from some of the bleaker world news. I arrived home late Saturday and then was back on a plane this morning: only to learn that Wachovia had been dispatched!

Deika Morrison blog

I wanted to point readers to the new blog of a friend of mine, Deika Morrison. She has an extremely interesting background: she served as a Senator and Minister of State for Finance and Planning for the country of Jamaica, is a business expert, and is a careful thinker. She's also one of the nicest people I know.

I continue to believe that so-called emerging markets are the well spring of innovative ideas in economics and business. Brazil, Israel, Russia, China, Jamaica are all interesting places where necessity has proven to be the mother not just of invention but innovation: Deika's blog should help illustrate what I mean.

SVOD: Tech Sector in Russia

This year's Silicon Valley Open Doors conference has been scheduled, the dates are November 20-21. This is the premiere opportunity to learn about the technology sector and venture capital opportunities in and around Russia and understand more about what is happening with Russian companies. Hope to see you there.

Give Back/Help Out

I (slightly) modified the right hand side of my blog to include some charities that I support. In some cases, I have good friends that have dedicated their professional lives to helping to build these organizations.

These don't even begin to scratch the surface of great organizations that offer great ways to help others. I listed these because I know a bit more about them personally and I'm confident that they do good (efficiently!). Another good friend, Edwin, recently added a blog post on Abilities United, which works with kids experiencing challenges in development and gives them special attention based on their needs. Take a careful look at Abilities United: they deserve support and all the help they can get.

Cisco launches Russia/CIS fund

Brent Marcus left a note that Cisco recently announced a Russia focused venture fund. I will be in Moscow in a few weeks and will try to get some first hand information to blog about.

Data grids and the Web

There's been a lot of talk recently about web 2.0, social networks, and cloud computing. To my way of thinking, these are very much overlapping categories. One useful technology that can be used support all of these models is the concept of a "data grid": high performance, distributed and reliable caching technology. On-Demand Enterprise has a good profile of AbeBooks.com, which uses Oracle Coherence technology to support their web site.

The First Rome

I spent the last two weeks on holiday in Italy. This was the first time I've taken two weeks off from work in nearly 20 years, so this felt like a much needed break. We traveled to Rome for several days, then on to the Amalfi coast, and across the country to Romagna and then spent our last few days in Venice. Three things struck me about Italy: the warm and passionate people, the incredible food, and the rich cultural and religious history that one encounters – in many ways is confronted with – throughout the country. Here are a few of photos and some thoughts along the way.

Rome sits under waves of consecutive civilizations. There is the indelible imprint of the Greek, Roman, early Christian, Byzantine, Gothic, Frankish, and ultimately modern world in Rome. It's not an exaggeration to suggest that you could spend many lifetimes absorbed in studying the remnants of each: the city is history alive. Our hotel was right down the street from the Colosseum: to best grasp the complexity of the operations of the Colosseum, you need to walk the insides. From here, you can see something of the scale, still impressive in a modern city. Many of the blood sport scenes involved animals that were kept below the center of the stadium. You can see the basic layout in this photo.



The next photo is the Arch of Constantine, the emperor that in many ways was responsible for the Christianity Europe still knows it today: he called the first Ecumenical Council at Nicea in 364 AD, which established the basic dogmatic creed for the faith. The arch also illustrates the engineering prowess of the Romans: note also that Italy still runs potable fountains throughout the city that were based on the acquaducts established by the Romans as well.



We visited the Vatican, including St. Peter's and the Vatican Museum. What an incredible wealth of Renaissance art. The scale of St. Peter's is awe inspiring, though the artistic motif is very much humanist. The church retains the old style of a domed church, so common in the Byzantine tradition; inside each dome is an elaborate series of paintings:



A haunting view of St. Peter in Glory (the dove represents the Holy Spirit):



It was, however, the Vatican Museum, that most impressed and surprised me by its scale and beauty. As we were touring with child, we had to move rather quickly through the museum to visit the Sistine Chapel, our top target. However, here is a view of one of the corridors leading through the museum. The museum is one of the main things in Rome I'd like to return to visit for a few days of sustained study:



When we left Rome, we traveled to the Amalfi coast for the better part of five days, partially for relaxation. A snapshot of the beach area below the cliff into which our hotel (La Terrazze: highly recommended for both location and the dinners) was built.



Here is the exterior of St. Andrea's Cathedral in Amalfi: note the cultural interplay between Byzantine and Arabesque styling; Amalfi was once a major port city and trading center in the Mediterranean.



A closeup of the mosaics of the twelve apostles, again, Byzantine in style.



The American novelist Gore Vidal described Ravello as the most beautiful place he had visited in all his travels. I concur. The church of St. Panteleone on the main piazza contained several throwbacks to early Christianity: the blood relics of Panteleone from 306 AD and an old icon of the virgin Mary. This seems to me to echo the early apostolic churches, which transferred dogma through liturgy, iconography and the veneration of saints, rather than scripture (the New Testament canon had not yet been formed at the time of Panteleone). Here are some fresco remains with an air of antiquity:



We spent several days in Romagna, a great family destination for relaxing on the Adriatic beaches. We explored the medieval hill towns by car. Stunning vistas overlooking valleys, olive groves and vineyards.



After Romagna, we had a few days in Venice. A remarkable city, though after a few days, we were glad to escape the throngs of tourists. Venice is a place to explore for three reasons: history, art and architecture. San Marco Basilica combines all three and is rightly considered the centerpiece of the city. Here are some external shots of Venice (photos in the interior of San Marco are forbidden, but the interior mosaics are stunning).





Switching gears: if the export of tourists is any indicator of macroeconomic conditions, pay attention to Venice. The tourists from Europe were, as always, predominantly German. But I was stunned by the throngs of Russian tourists, something I rarely encountered five years ago. Similarly, Japanese tourists still lead the visitors from Asia, but they were joined by lots of visitors from China. Of course, China and Russia have both been doing well, so perhaps this is evidence of well-known trends.

Solzhenitsyn remembered

I read Solzhenitsyn relatively late, much later than I should have. For me, his work will always serve as a warning about how readily humans can be trapped in a cycle of cruelty and exploitation: both as exploited and exploiters. I read dozens on essays remembering Solzhenitsyn over the last few days; I thought this piece from der Speigel captured the Western perspective quite well: he was never really understood by those who received him in exile, that he was sometimes thoroughly wrong headed, and that he was undoubtedly one of the greatest men of the last century.

WESOA 08 Workshop (second CFP)

S E C O N D C A L L F O R P A P E R S

4th INT. WORKSHOP ON ENGINEERING SERVICE ORIENTED APPLICATIONS:
"SERVICE-ORIENTED ANALYSIS AND DESIGN" (WESOA'08)

In conjunction with the 6th Int. Conference on Service Oriented
Computing (ICSOC 2008) http://www.icsoc.org/

Sydney, Australia, December 1st, 2008

WESOA Workshop Website http://www.wesoa.org/

Abstract Submission Due: Oct. 1st, 2008


OBJECTIVES
==========

In large-scale software projects that increasingly adopt
service-oriented software architecture and technologies, availability
of sound systems engineering principles, -methodology and -tools for
service-oriented applications is mission-critical for project success.
However, engineering service-oriented applications poses specific
requirements that differ from traditional software engineering and
service systems engineering (SSE) is not yet established.
Consequently, there is an urgent need for research community and
industry practitioners to develop comprehensive engineering
principles, methodologies and tool support for the entire software
development lifecycle of service-oriented applications.

The WESOA series of workshops addresses challenges of service systems
engineering that arise from unique characteristics of service-oriented
applications. Service-oriented applications closely resemble the
organisation principles of their application domains that are often
process-driven networks. They are compositions of service system
components that are provided by autonomous stakeholders based on
unique assets and capabilities. Therefore, service-oriented
applications often have a social dimension and can be regarded as
constituents of social service communities. It is the challenge of
service systems engineering to not only cope with these specific
circumstances but to capitalise on them with radically new approaches.
The WESOA series addresses these challenges and particularly
concentrates on the aspects of service-oriented analysis and design
that provide principles methodology and tool support to capture the
characteristic requirements of networked service communities and
transform them into reusable high-quality service system designs that
underpin and drive the holistic service-oriented development
lifecycle.

WESOA'08 continues a successful series of former ICSOC
workshops. During the past three editions, WESOA has demonstrated its
relevance by constant high numbers of contributions and participants.
Its impact is documented by consistent output of high-quality papers
that regularly satisfied requirements of Springer and led to a special
issue of IJCSSE.

Catching Up

Between work and holiday, I haven't been able to post much to the blog over the last 6 weeks. I am going to do a series of updates. Outside of work, I've been thinking a bit about the future of the web architecture, emerging markets and human social and religious history: post coming up related to all topics.

1) I was out of the country when Feedly was rolled out. I will talk about Feedly, why it is important and do a series of reviews on the technology.

2) I am hoping to publish details on a venture fund investing in Africa that I think will be quite interesting in the near future.

3) A longish entry on my recent holiday in Italy, including "the first Rome" is in the works.

Hope all that is of interest.
