The Singapore maths puzzle.

Now that I could lean back I guessed the answer for this puzzle after reading it a couple times mindfully. I think the answer is August 17. WHY? I will explain in detail. But first of all the answer I came across here (in NY Times) is obviously misleading and incorrect. They give July 16 as the answer, but their method is wrong because they eliminated both May and June and there isn’t enough information for such a step. What they should do is eliminate May 19 and June 18. Because these two dates (18, 19) are not duplicated in the list of dates.

Once they did so it would be clear from the conversation between Albert and Bernard that June 17 could also be eliminated. Because since Albert knows that June 18 and May 19 are not good candidates for DOB, neither can June 17 be. If June 17 was the date he would not claim “I don’t know the date of birth” because he already knows the month and there is only one date in this month that is June 17.

Bugs in your gmail?

I think I have found two bugs in gmail (by seeing its unwanted behavior)

1. This one has happened for years, now, solves itself in few hours. YOU CLICK on the email and it will not open. All other actions such as browsing through the boxes and delete etc would be working. SO you just gotta be patient for a while.

2. This one is more scary. Perhaps happening for a few months now. Seems like there is a bug that scatters the emails randomly and in large numbers (perhaps the ones it think are mass-notifications, it can drag some of your important message there if the message source is routine, that is your job-website or your bank emails) .

What happens? You can’t see a large number of emails, these are invisible, so after you read this, take my trick and check how many would be sitting in your email never read by you. You can’t and bet ya’ haven’t seen tons of emails that have been sent to you, few very urgent emails. Likely.
