'Night Mode' in Foxit Reader and Adobe Reader

If you are late night reader like me, this would be a very useful thing for you. I only found out about it because I was getting a headache reading black text against the white background in the dark.

A bit of searching through the inrernet for a night mode function in the Foxit reader, and I found it's actually very simple.

I use Foxit as my PDF reader, however Adobe works in a very similar way, so the following steps will work for both.

Please note that the steps may vary according to your version. The version I am using are:
- Foxit Reader:
- Adobe Reader: 9.1.0

1. First you need to find the 'Preferences' section.
In Foxit, just go to File and click Preferences.
In Adobe, right click on the document and select Page Display Preferences.

After this both Foxit and Adobe should be the same.

2. In 'Preferences', go to 'Accessibility'
Check the Replace Document Colors box then select Custom Color.

3. Change the colors.
Change page background to black and document text to white. However you might prefer the text to slightly grey if you are reading in complete darkness so that there is less contrast.

There you go! Now you can read the PDFs comfortably without straining your eyes.

If you have more tips regarding the 'night mode', be sure to comment below.

Spam, a Good Thing?

"You know, spam is a problem, but I would say that applications of artificial intelligence that can recognise what's in any picture are so much more important. I think it's worth the spam"

Sir Arthur Conan Doyle Didn't Write Sherlock Holmes

 Yesterday, I came across this book called The Mathematician and the Pied Puzzler. In the second chapter titled Ambrose, Gardner, and Doyle, which is in a play form, Ambrose and Byrd discusses a chapter from Science: Good, Bad, and Bogus, by Martin Gardner, titled “The Irrelevance of Conan Doyle”. In the chapter, it is said that there is no way that Arthur Conan Doyle could have written Sherlock Holmes because of his involvement in spiritualism. Instead of reading on this post, I would suggest you read the interesting conversation from the book itself. The chapter is only 5 pages long and you can get the eBook free from the Gathering 4 Gardner Foundation website.

Then, as their discussion continues, Byrd asks Ambrose why someone of the caliber of Martin Gardner would entertain the notation that Conan Doyle could not have written Sherlock Holmes to which Ambrose replies that obvious solution is that Martin Gardner didn't himself write that chapter! He argues that this is more reasonable than that  Martin Gardner has written that chapter and decides that he is going to publish it an journal.

Fast forward a 100 yrs, Cranby and Broad, discusses the Ambrose paper, the one Ambrose published in the Journal. They wonder how a reliable historian like Ambrose could have written that. That's where Broad says that his paper comes in where he maintains that Ambrose never wrote the paper!

So what exactly exactly happened? Why did Martin Gardner write the chapter "The Irrelevance of Doyle"? Well, according to the last paragraphs of the 'play', that whole chapter that Martin Gardner wrote was a hoax!

If you still haven't read that chapter in The Mathematician and the Pied Puzzler, I highly recommend you read it. It's a very interesting chapter.

China's Time Zone

China is the largest country with a single timezone. However, previously it used to have 5 different timezones which were unified in 1949 due to political reasons becoming the largest country with a single timezone.
China's Obsolete Time Zone

The second largest country to have a single time zone is India, which is less than a half of the width of China. If one were to cross the border of China and Afghanistan, they would have to adjust there watches by 3.5hrs, which is the largest adjustment on crossing a border of the country.
