Stations along the Science Railroad !

muyinteresante published this delightful map of progress of various branches of science and the personalities that helped them evolve. It took me a while to study the entire thing but I did end up with a pleasant sense of completeness even though the various 'scientists' (I use that term loosely to include philosophers, astronomy, biology and others) may have lived in periods separated by many years or even centuries....

The Year 2008 in Photographs
The year 2008 was an extraordinary year by any standard.

The Last Stand

The Last Stand
"Do not come up, I will handle them", these were probably the last words which Major Sandeep Unnikrishnan told his men as he was hit by bullets while engaging terrorists inside the Taj. He and fellow NSG commando Havildar Gajender Singh lost their lives as did Hemant Karkare, the celebrated head of the Maharashtra Anti-Terrorism Squad, while fighting the terrrorists. I feel so sad for their families and may God give them the strength to bear the loss. India has ...

How to speed up calculation and Improve performance of Excel and VBA
The key to increasing speed of calculation and improving performance of your excel worksheet and VBA code lies in understanding how Excel calculates (and re-calculates) each cell and resolves dependencies. Whenever an event occurs that causes Excel to recalculate (for example a cell is changed, a VBA code calls for re calculation or anything else), the entire calculation process is carried out roughly as follows: 1. Load workbook in memory when the workbook is first opened. 2. Track all dependencies and build ...

Alternative to Pivot Table in Excel
In one of my previous posts (How to read data from Pivot Tables using VBA), I talked about using the getpivotdata() function in VBA to read values from a Pivot Table.

Pivot tables are an immense help while working with data sets – they sum up the data into a small, neatly organized space. You can pick and choose the various values from ...

Adding Forms Scrollbars to your Excel Charts and Spreadsheets
One exercise that is done with almost religious fervor in all companies at the beginning of each financial year is the preparation of the budgets and targets for the next year. Every year a fresh faced newly recruited manager is identified, handled this dreaded responsibility and asked to present the first draft to the management team. And so the rookie spends a couple of nights pouring over multiple spreadsheets and a plethora of for complicated formulae and comes out with, ...

Simulating Multithreading in VBA using Excel

Simulating Multithreading in VBA using Excel
This article describes 3 ways of simulating multithreading in VBA using Excel. One feature that I sorely miss in the VBA's integrated development environment (IDE) is the ability to do multithreading. I think part of that comes from having worked in my previous avatar with Java and C++. In the past few days I’ve been thinking about ways in which one can ‘simulate’ multithreading in excel. (If you noticed, I said ‘simulate’ – you can’t actually multithread with vba – not atleast ...

There are three strong contenders competing for the market  share of the RIA (Rich Internet Application) development market - JavaFX, Adobe AIR and Silverlight. All three are aimed at the same market but carry strong influences of the parent company. Take Adobe AIR for example - Adobe hit it big with Flash a few years ago and is now used in more than 92% of all websites. Adobe makes its bucks by offering ...

The Presidential Race with the Halloween Twist

Posted on 24 October 2008

There has been ample supply of opinion polls and charts regarding the US presidential elections. I’ve been guilty of using Google Trends on this blog earlier. But over the past few days and weeks, the 24x7 in-you-face coverage of dresses, speeches, daughters/family, grand-fathers, great-great-great-grandfathers and anybody remotely in the vicinity of the candidates, has pushed me to a point where I am almost wishing that the election takes place over the weekend be spared the remaining weeks. However a recent story ...
