Wesley Chun, a developer advocate at Google, emphasizes the importance of integrating cloud computing and APIs into engineering curricula to prepare future developers. The document provides a detailed overview of Google Cloud Platform (GCP) and G Suite APIs, highlighting how to access and utilize them via REST APIs and Google Apps Script. It includes practical examples and resources for educators and developers looking to enhance their applications and automate tasks using these technologies.

2. Agenda and Why
● Not enough cloud computing in engineering curriculum
● Need to prep next-generation cloud-ready workforce
● Using APIs should be a nativeskill of new grads
● Introduction to Google Cloud (APIs)
● Using Google (Cloud) REST APIs
● Using Google Apps Script
● Inspirational app ideas (both GCP & G Suite APIs)

4. How to access Google APIs
● Two ways primarily
○ HTTP-based REST APIs (lower-level)
■ Need either simple API keys or OAuth2 client IDs
■ Any client library supported language
● Python, Java, JS, PHP, Go, Ruby, C#, Dart, etc.
○ Google Apps Script (higher-level)
■ Use APIs as objects in customized JS environment
● No need to code OAuth nor HTTP
■ Access 40+ Google APIs/services

API key (public data) vs. OAuth2 access (private data)

5. The first word on Security
Authentication ("authn") vs authorization ("authz")
● authn: you are who you say you are
○ login & passwd
○ handprint authentication
○ retina scan
● authz: okay, you are who you say you are, but can you haz data?
○ OAuth2 - mostly authz, but some authn
○ Mostly about 3rd-party access to data
○ Users must give YOUR app access to THEIR data
○ Most of the time when you see "auth", it refers to authz
Developers Console (devconsole)

6. ● Manage your projects
● Obtain application credentials
● En-/disable Google APIs

7. List (first 100) files/folders in Google Drive
from __future__ import print_function
from apiclient import discovery
from httplib2 import Http
from oauth2client import file, client, tools
SCOPES = 'https://www.googleapis.com/auth/drive.readonly.metadata'
store = file.Storage('storage.json')
creds = store.get()
if not creds or creds.invalid:
flow = client.flow_from_clientsecrets('client_secret.json', SCOPES)
creds = tools.run_flow(flow, store)
DRIVE = discovery.build('drive', 'v3', http=creds.authorize(Http()))
files = DRIVE.files().list().execute().get('files', [])
for f in files:
print(f['name'], f['mimeType'])

8. Migrate SQL data to a Sheet
# read SQL data then create new spreadsheet & add rows into it
FIELDS = ('ID', 'Customer Name', 'Product Code',
'Units Ordered', 'Unit Price', 'Status')
cxn = sqlite3.connect('db.sqlite')
cur = cxn.cursor()
rows = cur.execute('SELECT * FROM orders').fetchall()
cxn.close()
rows.insert(0, FIELDS)
DATA = {'properties': {'title': 'Customer orders'}}
SHEET_ID = SHEETS.spreadsheets().create(body=DATA,
fields='spreadsheetId').execute().get('spreadsheetId')
SHEETS.spreadsheets().values().update(spreadsheetId=SHEET_ID, range='A1',
body={'values': rows}, valueInputOption='RAW').execute()
Migrate SQL
data to Sheets

BigQuery: querying Shakespeare words
TITLE = "The top 10 most common words in all of Shakespeare's works"
QUERY = '''
SELECT LOWER(word) AS word, sum(word_count) AS count
FROM [bigquery-public-data:samples.shakespeare]
GROUP BY word ORDER BY count DESC LIMIT 10
'''
rsp = BQ.query(body={'query': QUERY}, projectId=PROJ_ID).execute()
print('n*** Results for %r:n' % TITLE)
for col in rsp['schema']['fields']: # HEADERS
print(col['name'].upper(), end='t')
print()
for row in rsp['rows']: # DATA
for col in row['f']:
print(col['v'], end='t')

This… with help from Google Maps & Gmail
function sendMap() {
var sheet = SpreadsheetApp.getActiveSheet();
var address = sheet.getRange("A2").getValue();
var map = Maps.newStaticMap().addMarker(address);
MailApp.sendEmail(EMAIL, "Map", map.getMapUrl());
}

17. Resources for Higher Education
● Education grant program
○ Teaching grants (per-course basis)
■ $50USD for students
■ $100USD for faculty & TAs
■ You'll barely use any of it… key: no need to give Google a credit card
○ Research grants
■ Larger amounts, granted for longer period of time
○ Turnaround time: 3-4 business days
● Teacher center
