Agriculture

Aquaponics

Good fish suitable for aquaponics

Below are the list of fish suitable for aquaponics

  1. Koi - can feed them almost anything
  2. Cat fish - can feed them anything (prefer low protein food) but make sure that you turn off lights in the night. They are active in the night.
  3. Goldfish - can feed anything. Have been domesticated for a long peridos of time. Also, this fish can share the tank along side Apple Snail.
  4. Carp - More like Koi. Koi is a inbred carp.
  5. Tilapia - Make sure that a few generations of Tilapia fish are not used for eating/sale as they may have parasites due to the bad fish feed being fed to these fish in commercial tilapia grow centers.

    Compost tea with aquaponics

    Though ocompost tea does not help in iron deficiency in the first few days, it will help in a aged system with lower PH. The video does not show how this compost tea is applied. One method to apply the compost tea is by spraying the compost tea on the plants of a aquaponics system. Also, using compost tea from a worm based compost is far better than the normal composting procedure as the risk of diseases is almost zero in the worm based compost.

Goldfish or Koi

Food for Goldfish

Spinach for the Goldfish
Preparing the spinach for the Gold fish

Vegetables for the Goldfish

Below are the list of fruits and vegetables the Gold fish feeds on.

  1. Peas - helps at digestion
  2. Lettuce
  3. Spinach
  4. Zucchini
  5. Carrots
  6. Cucumbers
  7. Apples
  8. Grapes
  9. Garlic
  10. Pieces of Orange (for vitamin C)
  11. Rice
  12. Broccoli
  13. Corn
  14. Beans

Other notable homemade plants

  1. Duckweed - Can also be used to filter water before it goes to the aquaponics system. It has also been used to filter heavy metals and this gives a general idea that water can be passed through a few layers of duckweed before it goes to acquarium and the first batch which contains most of the heavy metals can be passed to a biogas generator.

Remember to cook and chop all hard vegetables

No till

No till week management

No till scientific soil management

No till - Healthy soil generation

Competitive Programming

USACO

A very nice website that teaches you how to code and prepares you for a Computing Olypiad. Link here.

Google Code Jam

Old problems from the google code jam are a good place to start.

Al Zimmermann’s Programming contests

A little hard problems. Takes more time but then the solution also needs to be cleaner and so more effort and better clarity on problems.

Design patterns

A very good basic book on design patterns is at the wikibooks

C++

  1. Stephan T. Lavalej - Core C++
  2. Stephan T. Lavalej - STL
  3. Stephen T. Lavalej - Advanced STL
  4. Herb Sutter - C++11 memory model
  5. Herb Sutter - Concurrency and parallelism
  6. Bartosz Melewski - C++11 and concurrency
    His blog seems to have a lot of information regarding a lot of problems.
