Me Cook Food

When hunger strikes, you have to finally get cooking. For the first time ever, I served food out for myself like a civilized being (instead of devouring from the pots and pans).

On the table

  • Arhar Dal (Lentil)
  • Matar Pulao (Basmati Rice with Peas)
  • Aloo Pyaz ki Sabzi (Potatoes and Onions)
  • Sliced Tomato Salad

Took about 35 minutes to do this.


Got a disassembled futon at my place – and it’s assembly was quite a project. Took me about two hours to get it together. Photus phollow (wife took camera away to click our daughter, so the trail is a little incomplete).

Red Moon During Lunar Eclipse

This Moon (Lunar Eclipse)is a photograph (credits to Hemant Hariyani) taken during a lunar eclipse. Besides being a very beautiful sight, there’s a curious orange tinge on the lower left quadrant of the moon. My curiosity lead to the moonzoo (please search for the terms “blood red” on that page to see their reason) – which explains very briefly the cause of this. While discussing on a list, I realized that it’s confusing sometimes to visualize how exactly this happens – so I drew a diagram to get this straightened out.

Reason for the moon's blood red (orange) color during lunar eclipseRefraction causes light to bend – and when different colors of white light bend at different angles, that causes light to split up; the very cause of rainbows. This is enough theory, the rest is self explanatory in the diagram beside this text. As you can figure out, light from the sun, reflected refracted when passing through earth’s atmosphere – falls on the moon (and since only longer λ [red] reach out) it looks orange (or blood red).

It’s imperative to note, that the cause of this blood red color is very different from the cause of the blood red color we see when the moon rises on certain nights. That blood red is caused because the light coming from the moon gets scattered when passing through the earth’s atmosphere (more so, polluted atmosphere), which causes the red waves to fall on our eyes and make the moon look red. That is when the light from the sun gets reflected back on earth and on it’s way to our eyes, we see red (the whole thing looks red – unlike this phenomenon).

How to use a GPG key and encrypt stuff?

In the wake of increased attempts at online frauds and information stealing, I thought it only befitting to write this step by step tutorial down for people who have never heard of GPG.

Simply put, GPG keys are used to encrypt information. To “encrypt information” means to make the information secure in a way that only a particular person can see what it contains. In other words, you lock the information and only the person having the key to the lock can open it.

Use Case 1: Bank account information over emails
Never send your bank account information (your account number, the name on the account, type of account, card number etc.) by email. Don’t even send the bank/branch you hold accounts in. Nothing – just don’t send any information at all over email.

So then how do you send information if you need to? Use GPG. Follow these simple steps:

  1. Put your account information in a text file (using your favorite text editor).
  2. Save the file and call it, say, account.txt.
  3. Run these commands (on your Linux/Unix/FreeBSD box):
# curl -L '' | gpg --import
# gpg --output account.gpg  -r 0x0B5267B1E3662EBB --encrypt account.txt

If you try and open account.gpg in the same text editor, you would see some garbage in there, which can now only be decrypted by the person whose key you used to encrypt account.txt.
Command 1 (of step 3)  was where  you downloaded my key (hosted on the link and imported it into your gpg keyring.
Command 2 (of step 3) was to tell gpg to use  0x0B5267B1E3662EBB (which is a public key identifier of the key you imported) to encrypt the file account.txt.

For people who use Windows, there’s an easier way out: The steps above would be very similar – I am sure there would be a way to import a key into that program using a URL. So then, all you do is provide it the URL of the person whose key you want to import and it should be able to use that key.

The file  account.gpg is now ready to be sent over email (to the person whose key you imported in command 1 of step 3).

This tutorial is only about encryption – decryption is a separate topic. (..and my primary motive for this post is to let people emailing me quickly encypt stuff).
