MSP430 USCI libraries/examples

Dear TI,
Your examples code for the serial communications abilities of the USCI are terrible. Sending a byte at a time is not useful.

As I could not find anything online featuring a library I am working on one for everyone to use….
stay tuned for more.

A short foray into options trading

So I decided I would start trading options. It seems like many people are scared to trade options because of a stigma that they are risky and or complicated. While both can be true they really are simple instruments, at least in their basic form.

If you buy an option you are paying a premium for the right to buy or sell 100 shares of a stock at a given price. This price is called the strike price. The right to buy is called a call while the right to sell is called a put. Options have a fixed length when then can be used, or exercised. After this date they expire are are worth nothing.

Whats nifty about options versus buying the underlying security is that you neither own the security and don’t pay full price for it, instead you pay a premium, much like in insurance.

While stock xyz may cost $10 a share, a call strike price of $11 that expires in a month might only cost $2.00 a share. Similarly a put strike price of $9 might cost $2 a share. When a call option is above the strike price it is known as in the money, similarly for a put when it is below the strike price. Lets compare the call option to an underlying security for 100 shares.

Cost: 200 – 2,000
Max loss: 200 – 2,000
Max gain: inf. – inf.

Lets look at several potential prices of the stock.

@$10
Revenue: -$200 – $0
@$11
Revenue: -$200 – $100
@$12
Revenue: -$100 – $200
@$13
Revenue $0 – $300

This doesn’t look so good, you would have made money on the underlying stock compared to losing or breaking even on the option. Even though the stock move up %30 your income is $0. But lets look further. Say the stock increased %50.
@$15
Revenue: $300 – $500

Still the stock seems better right? Wrong. In order to get $500 you had to invest 10x as much capital, $2000, instead of $200! A better metric is your Rate of Return (ROR) which is how much the asset is worth/how much capital you risk.
ROR @$15: 100/200 – 500/2000
50% – 25%
WOW any investor would love a big return like that….
Additionally if you purchased $2000 in options you would have an extra $1000 in cash compared to the underlying stock.
Ok this tutorial is not that good but, there are many more out there…..
have fun!

How to make a baller presentation, look like a genius, and not use PowerPoint

You have a presentation coming up next week to pitch a new idea to a potential client. You need to look smart, be persuasive, and make sure your clients  don’t fall asleep at the boredom usually incurred via PowerPoint. I feel like Microsoft tried hard to make PowerPoint not generic and boring; I mean you can add animations and sound… regardless I have yet to create a PowerPoint that is really mindbogglingly awesome. So give up, and stop trying.

This golden nugget was shown to me a few years back at a recruiting presentation by Applied Trust, where I think I asked the only question, “What is the name of your presentation software?” “Prezi” was the short answer back.

Ya ok so what. Prezi is awesome for many reasons.

  1. Prezi is free (for most users)
  2. Prezi is cloud based (maybe a killer for those with sensitive data like me :()
  3. Prezi runs via a browser
  4. Prezi is on mobile devices
  5. Prezi looks good
  6. Prezi presentations logically connect data for the audience

All these are pretty obvious, but the last point is the most important. Many presentations I have viewed fail to adequately connect the dots. The motions provided by Prezi presentations do this in a subconscious way by adding perspective in addition to traditional things like text size and bullet-ing. There is a getting started on the Prezi site, but of course it will take some time to learn to Prezi.

Anyway, take a look on their site as well as the Prezi’s below,

“The Maverick Presenter” – This will be you soon

“Top 10 Reasons Java Programs Envy Scala” – Since you probably write code and present code

“My Perspective on Prezi”
