Hamburger Quiz

"If you plan to eat hamburgers throughout your life and are not a cattle producer, should you wish for higher or lower prices for beef? Likewise, if you are going to buy a car from time to time but are not an auto manufacturer, should you prefer higher or lower car prices? These questions, of course, answer themselves." 

Warren E. Buffett, Letter to Shareholder, February 27 1998

Book Recommendation #5

Red Flags that show a Company is in Real Trouble

  • Huge Goodwill figure in Balance Sheet
  • Current Ratio < 1
  • High Debt-to-Equity (High Gearing)
  • A very high number that is hidden in the notes, but not shown in the actual financial tables: Read the annual report backwards, because the stuff that directors really don't want you to find will be at the back.
  • Cash Flow not in line with Earnings: Compare FCF/share with EPS
  • Highlighted Adjusted EBITDA: This is directors' favourite number, because it always goes up
  • Key Management Changes: either they were brilliant and have been poached or they were rubbish and have been dumped
  • Directors dumping shares
  • Having only one "reliable" customer (eg. government)
  • Rapid Expansion: Expansion needs to be controlled

Color Theory

Note:  Black, White, Gray, Tan, and Brown are not separate colors on the color wheel, but are made up of different percentages of red, yellow and blue.

Core Color: the principle item in you ensemble, like your suit or sweater.

Accent Colors: second and sometimes third colors. To produce harmony between the core and the accent colors you can choose one of the following strategies:

  • Triad: three evenly spaced colors around the color wheel
  • Complementary: two colors that are opposite each other
  • Analogous: colors that are next to each other
  • Monochromatic: a lighter and darker version of the same color 

Note: Shades of white, black, gray or tan work well with all colors or may be worn together.

Note: Don't use more than 3 dominant colors, otherwise you will look like a clown.

Here is a guide, but only a guide:


Note: Nature has amazing color combinations. Take inspirations from it.

How to work in a lab

  1. Safety comes first. Know every single detail about safety regulation. Learn also first-aid.
  2. Be paranoiac about safety. 
  3. Obey all the lab rules. Some might sound stupid, but never ever attempt to judge them.
  4. Make your working environment comfortable.
  5. You may listen to music, but don't let it distract you. You have to stay concentrated.
  6. Respect all personal stuff. If you want to borrow something (even for a few seconds), always ask first.
  7. Move slowly.
  8. Do not make any assumptions or guesses. If you don't know something, ask your supervisor.
  9. First think, then act. Never lose control.
  10. Keep your workplace clean.
  11. Don't complain. Be patient. Think positive.
  12. Parafilm is your friend. 
  13. Label everything properly. Even if it is just water, do it.
  14. Have a nice pen and a pair of tweezers in your coat's pocket and never leave them unattended.
  15. Keep your drawer tidy.
  16. Open drawers slowly.
  17. Get some fresh air.
  18. Use a smaller glove. It allows precision.
  19. Change your gloves frequently.
  20. Keep a lab notebook and note down everything.
  21. If you are tired, drunk, sick etc., don't work in the lab. 
  22. Eppendorf is such a great company.

Most Important Macro Indicators (IMHO)

  • Trade Balance = Exports - Imports [Balance of Payments]
  • Current Account Balance = Trade Balance - Net Income from Abroad - Net Current Transfers [Balance of Payments]
  • GDP Per Capita [Real Economy]
  • GDP Growth Rate [Economic Growth]
  • Purchasing Power Parity - e.g. Big Mac Index - 
  • Government Budget Balance / GDP [Public Budget Figure]

 Some unusual but good indicators:
  • Lipstick Index: When finances are tight, consumers will forego large luxury purchases for smaller indulgences, like cosmetics.
  • Men's Underwear: If cosmetics are the small luxuries of tough times, men's underwear is the opposite: a basic necessity whose purchase can be pushed into the future until more disposable funds are available. Rarely seen, rarely replaced.
  • Divorce Rates: Financial problems strain a marriage, and make it more likely to break apart. 
  • Baby Diaper Rash Indicator: In a hope to save money, parents with newborns, babies, and toddlers try to cut back on costs by changing their child’s diaper fewer times throughout the day.

More accurately, it is also shorthand for:

  • It's Probably Overpriced
  • Imaginary Profits Only
  • Insiders' Private Oppotunity
  • Idiotic, Preposterous, and Outrageous

The Limitations of Radio

The air might seem capable of carrying an infinite amount of data, but that’s obviously untrue. How do we know? Radio stations are broken into channels to make sure they don’t overlap; various services, like cell phones and television transmissions, also have specific spectrum allocated to them.

The problem is interference, which is an issue that can impact a Wi-Fi router just like it can impact a radio station. If another device is using the same frequency and channel as your router, the performance of both may be reduced. A common solution is to change the channel setting in the router’s settings, but even this can sometimes fail.

Radio also has a limited range. The waves can’t penetrate dense objects and can only project a certain distance before becoming useless. A wall with heavy plumbing, or a large object like a furnace, could degrade Wi-Fi performance if they intersect the router and the PC wirelessly connected to it.

All of these limitations can be resolved by Ethernet. Official specs put the range of Ethernet at 100 meters (almost 330 feet), which is far more than is needed for a typical home network. There’s also no need to worry about interference. Ethernet is very much alive and well in homes that, for whatever reason, find Wi-Fi to be unreliable.
