So here is a news from strange but true department. Microsoft Excel blamed for gene study errors [bbc.com].
Microsoft’s Excel has been blamed for errors in academic papers on genomics.
Researchers trying to raise awareness of the issue claim that the spreadsheet software automatically converts the names of certain genes into dates.
Gene symbols like SEPT2 (Septin 2) were found to be altered to “September 2”.
This is what happens when you spend countless hours learning genome sequencing and very little about the software tools where your data goes. May be we need clippy back to warn people about such sticky situations.Continue »

So we moved to Wellington, New Zealand few weeks back (on 17th of July 2016, to be precise). After spending first 3 weeks in Jeff’s house and a hotel, we moved in to our rental home over the weekend (on 6th of August). Around the same time, the worst of Wellington winter waved welcome to us. We quickly learned how to stay warm indoors (layers, hot water bottles, rugs and more layers). Kids started going to school few days back and they are loving it. I bought a bike and managed to go out on few rides on the hilly roads of Wellington and found a strange for sale sign too.
Anyhow, Since we didn’t have internet connection until today, I thought I will start by sharing a few Excel links with you. Check them out to get your fix of spreadsheets.

First a little back story:
Last Friday (on 29th of July), we (Jo, kids & I) went on a day walk to Red Rocks. It is a rugged coastal walk near Owhiro bay in Wellington. It was a windy & cold day. So why did we brave the elements of nature on this 10km walk? To see seals of course. And we did find a few of them. We also caught glimpses of snowy peaks in Southern Island of New Zealand.
3 Seals Excel Puzzle
Now I can’t take you on the same walk thru internet. There is no Excel function that can teleport you from your office (or home) to Owhiro bay. So I made the next best thing.

Let’s kick start our Awesome August 2016 with a simple but very useful set of shortcuts. 5 shortcuts, one for each weekday.
- Monday ALT + M N: Open name manager. Very handy, if you have quite a few range names and want to edit / manage them. Remember, this is a sequence shortcut, that means, you press ALT M, let go of both keys and then press N.
- Tuesday CTRL + T: Create a new table from data in current region. For more on tables, check out our Introduction to Excel Tables page.
- Wednesday CTRL + W: Close the current workbook, while keeping Excel open.
- Thursday ALT + T O: Opens Excel options. Very easy to remember too.
- Friday CTRL F: Fridays can be hard to concentrate. Use CTRL+F to find what you want in the current workbook. Use CTRL+H if you wish to do a find replace.
