Problem with Microsoft Office
Goodness gracious me! Was having problem with Microsoft Office for Mac suddenly few days ago. It baffled me for a long while. Cause things just stopped working after restarting my machine. At first I thought there was a problem with Microsoft's preference files. So I deleted all my Microsoft related preference stuff in ~/Library/Application Support/Microsoft. Didnt work. Then I suddenly realised a lot of Rosetta-based apps (apps that are PPC-compiled) stopped working. So started looking on Google for Rosetta problems..... Finally!
Found the problem on MacFixIt:) Apparently updating to the latest Quicktime 7.2 with Java 1.6 installed beforehand creates a big problem as it breaks all Rosetta-apps. The fix is here:) Of course if u know a bit of sed will be useful cause it involves modifying all the ./ at the beginning of each line to / and changing all the " " (spaces) to "\ " in order to delete all the Java 1.6 files. I just used the replace function in vi to do it:)

Windows Vista
Is this supposed to be the long awaited Longhorn? To be honest, I couldnt be bothered. Engadget covered the launch event. It's nothing compared to when Steve Jobs launched the Apple iPhone few weeks back. Looking at Vista's screenshots, couldnt help but notice that it's so Mac OS like with all the aqua feel and colour:)) They even have these small apps called gadgets, which sounds suspiciously familiar like the widgets in Mac's dashboard. 3D window frames. Nice eye-candy but again, doesnt really float my boat. More photos of Vista (waste-ta-time) here.

NASCAR RC Vacuum
If one has $280 to spare, he/she should really get this vacuum. Remote control, NASCAR-themed, looks quite cool and probably quite powerful. Know quite a bit about vacuums now cause my Christian Fellowship leader is quite a cleanliness freak and we've just bought him a Black and Dekker handheld 12V 35W vacuum. Very nice to play with. So now, every time we go to his house, we would purposely throw some crumbs on the carpet just to use the vacuum:))

Apple IPhone: New Object of Desire
Such a sleek and beautiful looking device, it can only come from Apple. It's the Apple iPhone that comes with a full touch screen, built-in iPod (basically means mp3 + video player), motion sensors to detect portrait landscape mode. It even detects when the phone is brought to the ears and automatically reduce the display brightness and reduce the touch screen sensitivity so that users wont accidentally end the call while on the phone. Nice! But the nice part is that it runs OS X or at least a minimized version of it. Pretty cool (for a geek at least:P). Available only in US. Will be available in Europe in Q4 2007 and Asia, 2008. Just in time when my current O2 contract ends:) Summary of its features at Macrumors.

City Square Shooting Gallery
Leng Chye just told me he went to try shooting (real guns! real bullets!) at City Square Shooting Gallery. Only RM100 for 50 bullets. So cool! Must try it next time I go back Malaysia.

Even Slashdot makes a mistake
Bummer... slashdot's losing it a bit. One of their editors just put up a piece of artcile without checking it properly. The news is about Google and Nasa's collaboration. The article's all wrong cause it used an old article to point to a 'new' news. Worst still, the article also contain a link to a blatant internet squatting, GoogleNasa, which was registered to a certain Chris Kemp who seemed to have registered that domain on 29 September 2005, one day after that announcement by NASA. But, it seems that the site's been slashdotted already:)) as can be seen in this screenshot:
Better buck up, slashdot or you'll be losing more readers to digg.

BMW Sauber F1's new Supercomputer, Albert2
Should have seen this coming:)) Sauber Petronas's first supercomputer, Albert was based on AMD Opteron architecture. With Intel now sponsoring BMW Sauber, Albert must have been quite an eye sore in the sponsorship:)) Having worked in a company that was selling small supercomputers (oxymoron here:P), I've realised that it's all just about marketing and exposure. They're not really passionate about technologies and the amazing stuff they can do. It's just about selling more processors. At least that's the case in Malaysia as most of reps here are just marketing people. Gets a bit frustrating dealing with them. Anyway, here's the press release from BMW Sauber:
Albert2, presented on Thursday to international media representatives in Hinwil, is Europe's fastest machine used in industry according to the current Top-500 list. Albert2 is based on Intel processors and employed by the team for computational fluid dynamics (CFD). On average, it is about three times faster than its predecessor.
BMW Motorsport Director Mario Theissen: "Aerodynamics has a crucial influence on the performance of modern Formula 1 cars, with experimental work in the wind tunnel and computational fluid dynamics complementing each other. The launch of Albert2 means a decisive reinforcement of our CFD capacity. Unlike other teams, we are not planning to build a second wind tunnel but will continue to bank on the consistently expanding potential in this area. For the new season, we have set the goal of further reducing the gap to the top. Our new Supercomputer based on Intel technology is an important tool supporting us in this effort."
"The powerful Dual-Core Xeon processors perfectly match the high demand on computing power of the BMW Sauber F1 Team. The cluster based on these processors is one of the fastest in the world running computational fluid dynamic applications,” said Christian Morales, Vice President & General Manager of Intel Europe, Middle East and Africa.“With the move to Multi-Core we are able to meet the future demand on computing power of the BMW Sauber F1 Team for computational fluid dynamics."
Albert2 is based on Intel technology. It has 256 nodes with two Intel Xeon 5160 processors each, and each of these has two cores. This results in a total of 1024 cores. The capacity of the main memory is 2,048 Gbyte, the maximum computing power is 12,288 GFlops.
To illustrate the point for non-computer-experts, this means that Albert2 is capable of performing 12,288,000,000,000 floating-point arithmetic operations per second. To equal this computing power, all the inhabitants of the city of Munich (1.3 million) would have to multiply two eight-digit numbers every three and a half seconds for an entire year.
According to the criteria defined for acceptance in the Top-500 list of Supercomputers, this data makes Albert2 5.5 times faster than its predecessor, Albert. In the field, though - as with any computer - the software used plays a crucial part when it comes to speed. But even when running the complex programs for CFD calculations the increase is immense: when using the Fluent application, the average performance improvement amounts to a factor of three.
The architecture of the Supercomputer was developed by the Swiss company DALCO. A key objective was the achievement of high levels of efficiency as well as very good scalability, meaning that operations can be split among many processors without any significant loss of performance. The software for the CFD calculations is supplied by the German subsidiary of the American company Fluent, Inc., a wholly-owned subsidiary of ANSYS, Inc. since May 2006. Their specialists have been working together with the CFD engineers in Hinwil for several years, optimising the software step by step.
The Intel processors operate inside High Density Racks from American Power Conversion (APC). These combine power supply, cooling and environmental monitoring in an optimised rack construction. The Supercomputer consists of a total of ten racks, each having a width of one metre, a depth of 1.20 metres and a height of 2.30 metres. This results in a total length of nine metres and a total weight of 21 tons.
Albert2's enormous technological potential is used for analyses in the area of aerodynamics. By means of CFD aerodynamics components for Formula 1 cars are calculated on the computer, using numerical grid models that often consist of more than 100 million cells. CFD plays an important part in the development of front, rear and auxiliary wings as well as engine and brake cooling as another key area.
For the CFD specialists, the computing power provided by Albert2 means that they can perform their calculations either at higher speed or greater accuracy. Willem Toet, Head of Aerodynamics for the BMW Sauber F1 Team, says: "Thanks to Albert2 we can calculate more variants and more complex models which, in the end, results in an advantage on the stop watch. Of particular benefit is the system’s good scalability which gives us a very high level of flexibility.” Computational fluid dynamics does not compete with the work in the wind tunnel but complements it. During the development of the front wing, for example, numerous variants are calculated using CFD before the most promising of them are tested on the 60-percent model in the wind tunnel."
"A major advantage of CFD is the ability to simulate the air flow, which enables us to understand why one part is better than another. Consequently, there is a cross-fertilization between simulation and experimental aerodynamics," Toet added.

MacSaber
This is so so cool, if you got a mac laptop, you gotta try the MacSaber. It's a prog that uses Mac's in-built Sudden Motion Sensor to generate light saber sound every time you move the laptop. Not sure about the longevity of your machine after excessive use but what a way to start a conversation in a party:P
