HomePi – What we will build

As announced before with my post , I am doing my first blog series about building a sample DIY home automation for everyone to copy.

But what will we actually build?

The general idea behind this series is to show you which steps are needed to connect a google home to you raspberry Pi. It may sound like a small thing, but actually some components are involved

[Infographic] Geeks vs. Nerds

Stuck in a geeks world.. What does it mean? Actually there are “10” different characters that are not easy to seperate for the rest of the wolrd: Geeks and Nerds. But what’s the actual difference? An Infographic compiled by  http://www.mastersinit.org/ is explaining how to seperate them.

While Geeks are more likley to be found in positions like web developers or Entrepreneurs, Nerds are more often working as rocket scientists or reclusive professors. Both are likely to be IT professionals.

I don’t want to repeat all the figures, so just have a look to the infographic below: HostGator Promo Codes

Facebook Hacker Cup 2012 – How to solve Alphabet Soup

Alphabet Soup was by far the easiest problem in the qualifiers. I am not talking implementation but about understanding the problem. In some cases the “problem designers” did a good job in confusing me for at least an hour by their style in description. In alphabet soup’s case the problem was formulated as follows:

Alfredo Spaghetti really likes soup, especially when it contains alphabet pasta. Every day he constructs a sentence from letters, places the letters into a bowl of broth and enjoys delicious alphabet soup.

Today, after constructing the sentence, Alfredo remembered that the Facebook Hacker Cup starts today! Thus, he decided to construct the phrase “HACKERCUP”. As he already added the letters to the broth, he is stuck with the letters he originally selected. Help Alfredo determine how many times he can place the word “HACKERCUP” side-by-side using the letters in his soup.

Input

The first line of the input file contains a single integer T: the number of test cases. T lines follow, each representing a single test case with a sequence of upper-case letters and spaces: the original sentence Alfredo constructed.

Output

Output T lines, one for each test case. For each case, output “Case #t: n”, where t is the test case number (starting from 1) and n is the number of times the word “HACKERCUP” can be placed side-by-side using the letters from the sentence.

Constraints

  • 1 < T ≤ 20
  • Sentences contain only the upper-case letters A-Z and the space character
  • Each sentence contains at least one letter, and contains at most 1000 characters, including spaces

To solve it, simply iterate through the characters in the string, counting how frequently each of them occurs.

Quantum Leviation

As you seem to be geeky enough to read this blog, I assume that you all remember the awesome “hover board” from the movie back to the future. It was so much fun to watch Micheal J Fox ride this skate board with no wheels like crazy. I was so impressed.

Today I am impressed again, as I found a video on youtube the shows a quantum leviation demo. They are using a silicon wafer coated with some special copper alloy. Cooling the wafer down to very low temperatures makes it a superconductor. This way they are able to let the waver float over a magnetic rail.
