HIS item is about my personal research and, in particular, its recent development and progression, which may take it in a different and exciting direction. I currently work on assessment of registration algorithms, which I have described in some depth over at MARS — my research-related publishing platform. The latest item discusses everything at a more technical level.

Below lies the diagram which describes a possible framework, which is still at its ‘propsal stage’. The ultimate aim is to provide an e-Science workbench for medical image analysis. My experiments account for a mere subset, where image/volume sequences need be aligned.

The memo/statement titled “Reining in Google” is becoming rather popular in cyberspace. It discusses Google’s attempt to re-write copyright laws or at least reach a point of acceptance through persistence. They have already begun scanning books in 3 large libraries despite the looming lawsuits. I recently mentioned an item which Google had posted in defence of Google Print, but has it not gone out-of-hand already?

Where is the Google that I used to know? The Google that vowed not to do evil and even considered employing me as a system administrator. I am filled with mixed emotions. Before the IPO, Google reflected on Page and Brin. It is now that lunatic Schmidt and thousands of greedy investors.

UPDATE (05/11/2005): With reference to a previous mentioning of Microsoft book scanning, it is now official. Microsoft begin digitising books as well.

S it finally turns out, a Web-based Office suite, which could be an almost unprecedented step, is embarked on by Microsoft. This comes after numerous rumours about an innovative Google Web-based Office. These rumours, which spread like a plague and rapidly made the rounds, were just as quickly shattered by Brin. Google are in fact concentrating on OpenOffice at the moment.

It is worth pointing out that Microsoft have recognised Web-based applications as a major threat to their ‘milking cows’, namely Windows and Office. Office-like Web applications exist already although they are not cohesive. Returning to Microsoft,

Kicking off what he called the “live era” of software, Microsoft chairman Bill Gates said on Tuesday in the United States that the company plans to launch new Internet-based complements to its core products.

Gates said Microsoft is working on two products, “Windows Live” and “Office Live,” that create opportunities for the company to sell online subscriptions and advertising. Both are targeted at smaller businesses and consumers.

Interesting implications are worth pondering:

• Will MSIE-only compatibility be likely?
• Will non-Microsoft users be able to load Office document reliably using the Web-based equivalent?
• Will people eventually get used the the idea of adverts next to an Office document?
• How will subscription work and will it exclude certain people or be overly expensive?

Making that type of service available to anyone (i.e. without a paid licence) is suicidal. It could drive users away to platforms other than Microsoft Windows, unless of course there is a lock-in. This is why I imagine that there will be a catch. For instance, think of being permitted access to these Internet services depending on some requirements, e.g. premium features are exclusive to holders of a licence for the native version of Office.

Either way, Microsoft now open a peephole to a first glimpse, which I will of course rel="nofollow". Regardless, it looks rather appalling at the moment and is more of a placeholder, I presume. I quite like the standard-compliant clone below as it is not truly associated with Windows. It is a nice demonstration of the power of AJAX nonetheless, so I urge readers to take a look.

UPDATE: (03/11/2005) Joel re-affirms my point regarding Microsoft’s “half-baked” Web site.

Google have recently formed a pact with Sun Microsystems, best known for their work on Java and Solaris. They have just taken a re-assuring step — re-assuring to those who wish to see Microsoft monopolies fade away over the years.

Sun Microsystems are among the major maintainers, as well as the ‘funds engine’ behind OpenOffice. Finally we come to see that Google, who use OpenOffice in-house, contribute back to the Open Source community which they came from. They are now paying programmers to work on Open Office, which is some sense reminds me of begone “Google Office” rumours. They essentially use their powerful financial position to boost freedom, or so I choose to believe. It is no wonder Microsoft are scared.

Google plans to hire programmers to improve OpenOffice.org, a demonstration of its affinity for open source initiatives and one the company believes also shows sound practical sense.

It is worth emphasising that Open Office 2 was very recently released.

The stuff is extremely valuable, not just for toys

EHOLD the power of fibre-optics. Terabit connection, anyone?

Although we cannot speak of terabit connections yet, transmission throughput via wires is said to have reached that point. I once thought that our 2 gigabit backbone was something admirable, but think what would a 1000 gigabit enable us to do. Cross-site processors? Distributed computing environments that are also global?

A Japanese company has developed technology to transmit a two-hour movie in 0.5 seconds, the world’s fastest speed achieved with fibre-optic cables in the field, it says.

Wow! On my network connection at the University, a film might take a minute or two to transmit; that sure is fast enough for me. Does humanity even have the thirst for higher bandwidth, yet?

FTER teaming up with NASA¹ and forming a pact with Sun Microsystem, Google now sidle nearer to IBM. This move comes to show that Google are recognised as a market leader that is here to stay and further prosper.

SAN FRANCISCO (Reuters) – IBM and Google Inc. are collaborating to make it easier for office workers not only to search for local documents and personal e-mail but to delve deep into corporate databases, the companies said on Friday.

Can the men/women behind CCTV be trusted?

EMEBER the a popular phrase “Who is watching the watchers?”

Well, it appears as though, under the umbrella of Web 2.0, where visitors’ involvement is perpetually encouraged, we face yet another challenge: how can comments be moderated, articles ranked and statistics assembled reliably?

Can you truly trust a moderator? Need you ever moderate the moderator? If so, are you not getting into a cyclic moderation trap here? Slashdot have introduced the idea of meta moderation, where moderators can be penalised for unfair treatment of comments. For example, some would be aware of the effects a terrible day has on personality. Even in a peer review process, people are more likely to punish others passionately due to their own personal problems.

Why has this idea sprung to my mind and awoken in my consciousness? WordPress has recently seen some collaborative comment spam filtering, currently known as Akismet. I was involved in testing the plug-in (see my entry on ending comment spam) and I can finally give more details about it.

Comments are marked as “genuine” or “spam” and their status is shipped to a central repository where filtering is administered. At present, API keys are given to trusted bloggers. This is a handicapping property of the service, which may exclude many. It may even be interpreted as insulting to some. The API keys are intended to keep spammers out of any ability to flag comments badly, thus collapsing the system and breaking everybody’s long-taught filters. Essentially, there is the possibility of filling the engine with noise, which makes it utterly unusable.

Finally, the scenario above begs for the question: how can the moderators — the test set which flags spam — ever be moderated if there is no trust or moderation atop the moderators? We are yet to discover where it will all end up. I believe they may be an exclusive ‘army’ of flaggers while the remainder will be just client of the Akismet filtering engine.
