Solar Eclipse Day

Today there is a total Solar Eclipse; too bad I’m in California..won’t see the entire thing. However, there is a livestream, courtesy NASA! My mentor booked his ticket to Idaho about 4 months ago, because well…geek LOL.

Finished my third assignment for my Nanodegree

Got this response, which was really encouraging!

I was also recruited by yet another Valley company. It’s a student-tier, though, so I apply for a day to meet their peeps and network, etc. But I’m on their radar, and they’re a pretty large company that’s under the umbrella of a Big Four company.

Moving on…

Playing with Turtle!

This little programme makes the line violet, and then fills the shape in yellow once it’s done!
Yes, the turtle’s name is “brad”. calling turtle.Turtle() initializes the turtle.
The window class is calling the background window and setting this.
I’ve played around with Turtle before, and done a similar experiment in Haskell and Processing.

import turtle
"""
draw a square in turtle
"""

def draw_square():
	window = turtle.Screen()
	window.bgcolor("green")
	
	brad = turtle.Turtle()
	
	brad.color("violet", "yellow")
	brad.begin_fill()
	
	brad.forward(100)
	brad.right(90)
	brad.forward(100)
	brad.right(90)
	brad.forward(100)
	brad.right(90)
	brad.forward(100)
	brad.end_fill()

	window.exitonclick()

draw_square()

I also sent my first Twilio message!

Awesome stuff! If I had gone a day earlier to BayHac, I would have gotten to visit their offices; a friend (from our Haskell group) works there! Now I understand a bit of what he does! Ah..so cool!

Yes, I have a flip-phone :( It says “My name is Krystal. Woot!”

Also…went sailing!

We made it all the way to Malibu, and saw dolphins!

A race was going on…

The powerboat in the middle is usually the officiating boat.

Malibu!

These guys were flying overhead

We had an air force vet on board, so he told us what it was. I’m not that savvy, although I know a few planes (like the A-10, etc).

I had to take a photo…

This is the name of a classmate of mine from high school! Yeah, so I went to a predominantly East-Indian descent high school…

And of course…sea lions!

Plan for this week

I’m going through the Nanodegree coursework (on to the next chapter) during the day
In the evenings (until my class starts, on August 30th), I’ll be teaching myself some Mathematica. I have a 15-day trial, so that sounds about right, using the online version. Another tool in the toolbox that I think is very useful for what I’m interested in.

In the top 500

Katas solved

Smallest value of an array

def find_smallest(numbers,to_return):
  try:
      if to_return == "value":
          a = sorted(numbers)
          #print a[0]
          return a[0]
      elif to_return == "index":
          a = sorted(numbers)
          b = a[0]
          #print numbers.index(b)
          return numbers.index(b)
      else:
          #print None
          return None
  except:
      #print None
      return None

percentage of array. So many issues with this one. Nine reported issues, but was able to get all test cases to pass.

function percentageSumArray(arr){
        if ((arr == null) || (arr.length) == 0){
          return false
        }
        else{
          var total = 0
          var total1 = 0
          var num = 0
          for (var i = 0; i < arr.length; i++){
            total = total + arr[i]
            if (arr[i] > 0){
              num = num + 1
              total1 = total1 + arr[i]
            }
          }
          var percent = ((num / 100) * total)
          if (percent == 0){
            return false
          }
          else if ((percent < 0) && (total < 0)){
            return false
          }
          else if (isNaN(percent) == true){
            return false
          }
          else{
          var percent2 = ((num / 100 ) * total1)
          var percent1 =  Math.round(percent * 100) / 100
          return percent1
          }
        }
        return
}

find vowel in string and return its index (using one-based indexing)

function vowelIndices(word){
  var arr = []
  var word1 = word.toLowerCase()
  for (var i = 0; i < word1.length; i++){
    if (word1[i] == 'a'){
      arr.push(i+1)
    }
    else if (word1[i] == 'e'){
      arr.push(i+1)
    }
    else if (word1[i] == 'i'){
      arr.push(i+1)
    }
    else if (word1[i] == 'o'){
      arr.push(i+1)
    }
    else if (word1[i] == 'y'){
      arr.push(i+1)
    }
    else if (word1[i] == 'u'){
      arr.push(i+1)
    }
  }
  return(arr)
}

had to do a bunch of validations to get this to pass. I could refactor this, but I basically wanted an old kata to pass.

function pizzaPrice(diameter, price) {
  var area = Math.PI * ((diameter / 2.0) *(diameter / 2.0))
  var ppi = price * 1.0 / area * 1.0
  if (ppi == 0){
    return 0
  }
  else if ((price == undefined) || (diameter == undefined)){
    return 0
  }
  else if (price == null){
    return 0;
  }
  else if ((isNaN(price) === true) || (isNaN(ppi))){
    return 0;
  }
  else if (price === NaN)
  {
    return 0;
  }
  else{
    return eval(ppi.toFixed(2));
  }
  
}

strip whitespace and compare string A and B. If A and B are equal after sorting (anagram), return true.

function isAnagram(stringOne, stringTwo) {
    if ((stringOne == "") && (stringTwo == "")){
      return true
    }
    else{
    var a = stringOne.toLowerCase().replace(/ /g,'')
    var b = stringTwo.toLowerCase().replace(/ /g,'')
    var c = a.split('').sort().join('')
    var d = b.split('').sort().join('')
    if (c == d){
      return true
    }
    else{
      return false
    }
    }
    return
}

Summy (has a 0 out of 4 % satisfaction rating as I write this). What they wanted was sort of confusing, but was able to pass tests.

def summy(String):
    try:
        total = 0
        for i in String:
            total = total + int(i)
        return total
    except:
        total = 0
        a = String.split(' ')
        for i in a:
            total = total + int(i) 
        return total

replace every instance or conjugated version of ‘meep’ (lowercase or uppercase) with ‘beep’

function meepOut(quote) {
    quote = quote.replace(/meep/g, "beep")
    quote = quote.replace(/Meep/g, "Beep")
    return quote
}

Sort string index by evens and then odds, then join strings

function sortMyString(S) {
    
    var arr = []
    var arr1 = []
    for (var i = 0; i < S.length; i++){
      if (i % 2 == 0){
        arr.push(S[i])
      }
      else{
        arr1.push(S[i])
      }
    }
    var a = arr.join("")
    var b = arr1.join("")
    var d = (a + " " + b)
    return d
}

Get the integer part and separate the fraction * 8 slices

def how_many_pizzas(n):
    a = 64.0
    c = n * n
    b = (c / a)
    
    d = list(str(b))
    d1 = str(b)
    
    
    integer = int(b)
    
    length = len(d)
    finddot = d.index('.')
    
    secondpart = d1[(finddot):length]
    
    fraction = float(secondpart) * 8
    fraction1 = str(fraction)
    fractionfirst = fraction1[0]

    return 'pizzas: {}, slices: {}'.format(integer, fractionfirst)
