Ever worked with messy data? Whenever I get xls or csv files, I won’t be so naive to think that the data is clean. Very often there are trailing spaces or even worse newline characters at the end of certain cells, not to mention typos and stuff. I have to physically go through all data cells to do clean up before getting them into the database. It’s such a pain, and I probably won’t notice anything until errors occur later on. Chances are I missed a few clean ups and now I would have to re-import the dataset into the database again. ...

Say for example, if you type in “short CEO”, WolframAlpha will give you the info on the short CEO such as his name, his business, and so forth, while google will give you anything related to your search words. ...

This tool made use of the google searches people around America made to predict if there are any flu outbreaks. The idea behind it is that, there is correlation between people getting sick and people who will do a “flu symptoms” search. However, it is not meant to be an accurate tool because there are people like the elderly who will not go online.

My goodness, google map is going wild… Now we can even use it to look for real estates… I am worried for some of the real estates listing websites… Just go to google map, then type in the neighborhood address, then click “Show search options”, select “Real Estate”, that’s it.
