GNUplot is a versatile graphing and plotting tool which is more than sufficient for all your graphing needs. Some of the impressive features that I appreciate are:
- It provides great flexibility when you want a script to automate your graphing. I had to run several hundred simulations and plot the data for each and every one of them. Without GNUplot, i could not have done it.
- It can produce graphs in many different formats (both in vector and raster formats)
- It has nice curve-fitting tools
- It is free!
So, lets get started.

I was introduced to Couchsurfing.org quite sometime back by one of my friends. It sounded interesting, but I was not too keen to try it out then. However, recently I have been really interested in going out and exploring the possibilities. I decided to join in a group of people to hike Gunung Panti mountain in Johor Bahru, Malaysia. The hike was organised by Philip from couchsurfing. Philip is a Filipino and is a regular hiker and had hiked Gunung panti 8 times before. The group seemed large, with 25 people in it. I made a choice based on my gut instinct and joined them on the hike last Sunday.

I prepared myself for the hike, packed a sling bag with essential items from a list made by Philip. Everything was being communicated to everyone in the group through a Whatsapp group created out of convenience. The estimated expense was 30-40 MYR or Ringgits. As I was staying up for long hours for quite a few days, i was finding it difficult to sleep early so that I can get up at 5 AM on the day of hike and get ready. Eventually, I went to bed at 2 AM and the excitement did not let me sleep properly.

If you are working on a big project with large directories containing several source files, then there is a good chance that you might need multiple files to be open at the same time. And if you use vim editor or rely more on terminal (CLI) in a linux environment to accomplish your work, then you definitely would have felt the need to manage the multiple terminal windows that lay scattered around all over the desktop. I tried other options like terminator etc., but my friend recently introduced me to Byobu, and I find it to be the best and straightforward option to manage multiple terminal windows.
To install Byobu:
// Install byobu % sudo apt-get install byobu
To use it:
Open a terminal window (Cntl+Alt+t)
// just type byobu % byobu
And, now use the following key-bindings to create new terminal window panes and navigate between them.
F2 - Create a new window F3 - Move to previous window F4 - Move to next window F5 - Reload profile F6 - Detach from this session
For more key-bindings and info, go to: http://byobu.co/documentation.html
Here's a screen-shot of how i looks:
I hope this helps. :)

Hi everyone, so I am back on the blog after quite a long time. This time, I will share my first ever experience as a tourist in a foreign land (Cambodia). It’s been over a year for me in Singapore, but I came here as a student. All this while, I had some very nice experiences, but could never find time to write about them. But this one is special and I must document it. This should also help other prospective travelers to Angkor Wat, Cambodia.
So, I planned this trip at very short notice. I had no group at first, but wanted some company as I lack experience as a lone ranger. I managed to get 3 of my friends on board at first, but 2 of them could not manage to stick around. Finally, I and Sumedh (my senior at NTU) went on with the trip. We flew Tiger Airways from Singapore on 27th October (Sunday) and reached Phnom Penh at 12:30 PM local time. The flight was short and easy. Since the trip was only 2 days long (we had to return on Tuesday morning), our main purpose was to visit the great Angkor Wat temple. To be honest, I had no clue about anything else in Cambodia. This is not a good practice and I recommend that you know quite a bit about a place before you pack your bags.
