Commemorating Muki (Arrianto Mukti Wibowo)

##2011 REPOST##

It’s striking me to know the news that you already leave forever from a friend. We did very few communications and, in fact we really never meet in person. One thing for sure though, we share the same interest in information system governance domain. But this unbelievably way of interaction does not hinder me to get a nice impression of how spiritful you are. Since then I claim myself as part of those who keep an eye to your website. You even pave the road and the opportunity for community learning. You open all resources which are somewhat others might have kept in a securely locked top secret folder. This is what exactly I’m doing right now, broadcasting your knowledge to the whole universe. Trust me, I’m learning to follow your move.

Now the Almighty has decided to take you there. I don’t have any information of the cause of your leaving, but anyhow, I would say you are probably better there. God loves you more, and definitely, sending you there is much much best place to go. Please need not worry buddy, because you have stocked your own remembrance with a handful of fruitful, knowledge, which is long lasting and will not fad away or be corroded in any other way.

My thoughts and my heart sincerely are with you and your family. I cherish all the good things you have delivered to the world. Good bye Muki.


2012 Conf-IRM

The deadline is closer! Must hurry up…wish me luck guys so I can make it this time, this year, after a totally dark hour in 2010.

Conf-IRM 2012
Theme: Information Systems and Accountability in a Digital World

Dr. Michael Häupl – Mayor of Vienna
Brigitte Jank – President of the Vienna Chamber of Commerce and Industry

Vienna University of Economics and Business, Vienna, Austria
May 21-23, 2012

Now open for submissions: Click here to access the Easychair System for submitting your research work, teaching cases, and proposals for panels and tutorials.

This conference aims to bring together information resource management and accounting researchers, educators, and professionals from all over the world to discuss the frontiers of Information Resources Management and Accounting Information Systems, especially to exchange topics, viewpoints and findings that may be radical or even controversial. In the current economic climate, IT managers and academics continue to contemplate over the critical challenges of how to reduce, monitor and control operational IT risks within enterprises to achieve greater organisational transparency and provide environmental sustainability. Responsible IT governance and management is at the core of on-going debates arguing for wider accountability to all involved stakeholders including private and public organisations, and users and citizens. While the efficiency and the effectiveness of operations continue to be at the forefront of IT performance assessments, new dimensions including social and environmental responsibilities are demanding more attention in total responsibility approaches. Regulation is (re-)gaining grounds not only in specific industries (such as financial services) but also across sectors, e.g. with low carbon regulations driving transparency through carbon footprints. Organisations need to re-act by re-evaluating their IT decision making and assessment approaches, change management systems, information technologies and methods in an effort to improve control over their information and technologies guided by new and well aligned organisational objectives. In this context, Conf-IRM 2012 aims at providing a current account on the array of different ideas and initiatives in globalised and digital world promoting Accountability within the discipline of Information Systems.

Do[t] Anything

Imagine the world wide web with infinite identification where everyone can put whatever they want as their internet domain naming address, virtually everything. Now, it is no more imagination. You really can put any name you want, for instance as Or for governmental area, you can simply type Or for education purpose, you can use www.children.kindergaten..

After a series of long discussion and debate between internet communities, business groups, and governments, the decision was made on Monday, 20 June 2011 to enter a new order of top-level-domain management ever. The Internet Corporation for Assigned Names and Numbers (ICANN), the organization that coordinates the Internet’s addressing system, approved to increase number of domains that can be used for any industry, community or interest group for their specific needs from that previously limited to only some domain like,,, or Ratification made by ICANN now provides users more choices to apply name for their own generic top-level domains (gTLDs).

Obviously, this whole new ways of addressing domain will bring impact on the way people search and use information. For trademark holders this ruling would make their brand, innovation or process are more protected by ensuring more authenticity and authorization power for their properties. From now on, no one will be allowed to apply for a particular name, such as dot.Ritchi, without written approval from me. For a local or a specific country, like Thailand, who wants to utilize more internet activity delivered in their local language, gTLD will enable them to their own language structure, not only English.

gTLDs implementation is also seen as a way to prevent or to reduce cybersquatting activities. Value of cybersquatting would be greatly reduced as no logical need for bad faith squatters to keep such dot.something to further sell it to another party with marginal cost. Reflecting the burst back in 2000, we have seen how many unreliable (or perhaps unrealistic) start ups failed to show real business value due to unproven business plan. These young IT folks sold huge number of non substantial unbacked business domains to some sloppy venture capitalists in exchange for stock to make them new billionaires. And the trend continued, at least to some degree until gTLDs endorsement, with the selling of variety of these dot.coms/orgs/nets/etc which bears little meaning to the squatters (but great value to real business)to subsequently sell them to companies or groups with high prices.

With such promising merits offered by gTLD, it would be a worth move to get the new domain. But no pain no gain. In order to obtain your dreamed domain name, you have to dig out your wallet a way out deeper. ICANN requires any interested group to spend $185,000 to subscribe for their desired domain. This big investment does not come with unsubstantiated reason. One of ICANN’s argument is that it needs to cover application processing expenses and providing service for litigation and any related issues might arise. From applicant side, this would entail a detailed business plan, clear IT strategy especially in B2B, and likely a ready legal policy to tackle competition and ownership issues. This indicates how serious and fully-controlled the organization and of this new domain naming system will be.

Nevertheless, with such big opportunity, and big money too, there is still challenge in dispute over who will be the most proper one to be entitled with particular domain. For example, there may be a conflict over the use of dot.ritchi between me and the other guy in some US state. If this occurs, auction to the highest bidder will likely be done to overcome the dispute. Auction means more money, and I ain’t got that huge bucks though. So perhaps I will let this other hamzah ritchi to win. C’est la vie.

Some analysts voice some concern over a predicted decline in traffic, and consequently profits, of search engine industry. Under the new system, users are likely to by pass google or yahoo to get their specific needs. They do not have to think what queries to type in search field as they can straightforwardly go to their destination which they knew already. But as Lenny Kravitz said, it ain’t over ’till it over. I will not take a hurried opinion to judge whether Google with its entire kingdom, will diminish.

According to the site, ICANN will soon begin a global campaign to tell the world about this dramatic change in Internet names and to raise awareness of the opportunities afforded by new gTLDs. Applications for new gTLDs will be accepted from 12 January 2012 to 12 April 2012. For quick introduction, a seven minutes video of the coming gTLDs can be watched below or you can see it in ICANN homepage. A new platform emerges for everyone to grab and monetize opportunity in digital environment, and that the internet is all about, to do[t]anything.

What..the end of the RDBMS?

Can’t give opinion on this now, just check it out…sourced from this link

The End of a DBMS Era (Might be Upon Us)

Michael Stonebraker

June 30, 2009

Relational database management systems (DBMSs) have been remarkably successful in capturing the DBMS marketplace. To a first approximation they are “the only game in town,” and the major vendors (IBM, Oracle, and Microsoft) enjoy an overwhelming market share. They are selling “one size fits all”; i.e., a single relational engine appropriate for all DBMS needs. Moreover, the code line from all of the major vendors is quite elderly, in all cases dating from the 1980s. Hence, the major vendors sell software that is a quarter century old, and has been extended and morphed to meet today’s needs. In my opinion, these legacy systems are at the end of their useful life. They deserve to be sent to the “home for tired software.”

Here’s why.

If we examine the nontrivial-sized DBMS markets, it turns out that current relational DBMSs can be beaten by approximately a factor of 50 in most any market I can think of. What follows are a few examples.

In the data warehouse market, a column store beats a row store by approximately a factor of 50 on typical business intelligence queries. The reason is because column stores read only the columns of interest to the query and not all of them. In addition, compression is more effective in a column store. Since the legacy systems are all row stores, they are vulnerable to competition from the newer column stores. The interested reader can start with “C-Store: A Column-oriented DBMS” to explore this topic further.

In the online transaction processing (OLTP) market, a lightweight main memory DBMS beats a row store by a factor of 50. Leveraging main memory and the fact that no DBMS application will send a message to a human user in the middle of a transaction, allows an OLTP DBMS to run transactions to completion with no resource contention or locking overhead. The interested reader can start with “The End of an Architectural Era (It’s Time for a Complete Rewrite)” to explore this topic further.

In the science DBMS market, users have never liked relational DBMSs and want a non-relational model and query facility. This was the topic of my last ACM blog, “DBMSs for Science Applications: A Possible Solution.”

If you are storing Resource Description Framework (RDF) data, which is popular in the bio community and elsewhere, then “Scalable Semantic Web Data Management Using Vertical Partitioning” points out that column stores are very good at certain RDF workloads. In addition, other ideas, such as “RDF-3X: A Risc-style engine for RDF,” will beat conventional DBMSs in other situations. Lastly, native RDF engines (e.g., Virtuoso, Sesame, and Jena) may well gain traction. The point is that something else will beat conventional row stores in this market.

Text applications have never used relational DBMSs. This was pointed out to me most clearly by Eric Brewer nearly 15 years ago in the early days of Inktomi. He wanted to use a relational DBMS to store the results of Web crawling, but found RDBMS to be two orders of magnitude slower than a home-brew system. All the major Web-search engines use home-brew text software to serve us search results. None use relational DBMSs.

Even in XML, where the current major vendors have spent a great deal of energy extending their engines, it is claimed that specialized engines, such as Mark Logic or Tamino, run circles around the major vendors, according to a private communication by Dave Kellogg.

In summary, one can leverage at least the following ideas to get superior performance:

A non-relational data model. If the user’s data is naturally something other than tables and if simulating his natural data model on top of tables is awkward, then chances are that a native implementation of the natural data model will significantly outperform a conventional RDBMS. This is certainly true in scientific data.

A different implementation of tables. If something other than a row store accelerates the user’s queries, then a direct implementation of the relational model using non-row store technology will run circles around a conventional RDBMS. This is true in the data warehouse marketplace.

A different implementation of transactions. Current row stores give you a “one size fits all” implementation of transactions. This can be radically beaten if a user has lesser requirements or if the system can take advantage of workload specific features. This is true in the OLTP marketplace.

One of these characteristics is true in every market I can think of. Hence, in my opinion, the days of a “one size fits all” monolithic DBMS are at an end. The replacement will be a collection of vertical market specific engines, with much higher performance.

You might ask, “What if I don’t care about performance?” The answer: Run one of the open source relational DBMSs. They are mature, reliable, and, best of all, they are free.

You might also ask, “I am dug in deep with my current vendor(s). What do I do?” The answer: Take some portion of your DBMS budget and allocate it to new solutions. Over time, you will move onto better technology.

The power of Community(2.0)

Did you ever feel that every pieces of your footstep in your life at a point in time may at least lead you to a wiser and bigger meaning of something? well I maybe one of those who thing that way. I see that mailing list and my reading during the last two weeks lead me to to start understanding how collaborative working can rule the new competition.
I’ve been reading this cool book for about two weeks from the first day I bought it at a bookstore in Bandung. Oh yeah, I forget. Anyway, the book is entitled Wikinomics. Pretty eye catching for an impulse book reader like me by just looking at the cover. Though I read its Indonesian translated version, the message is pretty clear and delivered nicely. It’s a pity that I’m in the middle of my peak time to finalize some stuff for the end of January.
Authored by Don Tapscott and Anthony D. Williams, the book is promising a new look of how information society revolutionizes. It’s not food company vs food company anymore. It’s not also rivalry between two competing value chains. It’s way bigger than that. What happened now is global competition. I’m not talking global in a “multinational” or “enterprise-wide” sense, but global in the sense that all people are powered by the new version of the little e- (e-business, e-commerce, e-money, e-banking) to enhance new innovation, new product and even bigger, a new paradigm. Collaboration, seems to be the most looked up buzzword to define how people are now enabled to create a new kind of working style, dumping self and license protected product and services.Whole range of collaborations now exist to demonstrate the capability of shared-working: blogs, wikis, peering, open source application, and to my knowledge, mailing list.

In Indonesia, the wave of collaboration is also moving on. I realize the going by looking how community media is having its evolution. From 20 mailing list I have been joining so far, at least now I’m part of some mailing lists that serve for certain domain of knowledge. One community/ mailing list, KOM-TEK, stands for KOMputer TEKnologi, is an Indonesian -based mailing list dedicating for improving the member skill. It is a place where few humble and IS experienced people are dedicating themselves for the development of Indonesia human resources, especially in ERP and other enterprise application. They hold ranges of free ERP trainings given that internet connection is available. As a result, now more people are coming that are competitive for ERP human resources market after they graduate from the training.

Another mailing list, IPOM-APICS are opening opportunity for those who are interested in industrial engineering and its related field. The mailing list is associated with APICS (a non profit organization that offers three internationally recognized professional certification programs:CPIM – Certified in Production and Inventory Management, CFPIM – Certified Fellow in Production and Inventory Management, and CSCP – Certified Supply Chain Professional designation. Since its formation, the mailing list has been able to provide its member access to knowledge in operation management.

Having read this, I guess it’s not impossible to create new innovation from this community controlled area. And that’s what I call the power of community.

Information Relevancy-past&present

I want to propose a hypothesis or anything similar like that. You may or may not agree with my opinion.But if you put yourself back in early 90s or perhaps much further than that, say 80s, many of us really find it’s hard to get needed information channel for your decision making purpose in the sense that the channel was not provided sufficient enough. Organization business process data still being captured in a proprietary IS infrastructure in a so called legacy. Different division means different data structure, application logic/algorithm and communication standard. The premature stage of communication protocol like TCP/IP had not provided a quick way to obtain information. Put it in simple word, biggest problem is the lack of information channel that caused inability to get proper information for next course of action.
On the other hand, the emergence of web 2.0, search engines, browsers development, and many embedded web based applications are seen a milestone of present information processing age. The now act now as the frontier to open a new order of information discovery. Yet, organization still suffer from getting right information in right time, right context and right way. Even worse, we are drawn and chocked in a drastically huge volume of data or information, coined as Information Overload. Try googling with the word “computer”, n you’ll see 1,020,000,000 search result out of it. But to identify which context nicely fit to your desire is another problem I suppose.
Reflecting to said above explanation, I think that management or organization still face difficulties in obtaining a relevant information for decision making, only to a different extent. In the past we deal with information shortage, n now we face information overload. Until business and IS align together, the problem of information relevance will remain unsolved.
