"A little bit of slope makes up for a lot of y-intercept"

01/13/2012. From a lecture by Professor John Ousterhout at Stanford, class CS140

Here's today's thought for the weekend. A little bit of slope makes up for a lot of Y-intercept.

System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

Basic Steps

Clarify and agree on the scope of the system

User cases (description of sequences of events that, taken together, lead to a system doing something useful)
- Who is going to use it?
- How are they going to use it?

A simple script in python3.x to

Send text emails.
Send to multiple clients.
Send multiple attachments (including images, videos, audios and compressed files)

To send email from the local SMTP server (localhost) it is assumed that a mail transfer agent (MTA), like postfix, is already configured on your local system. If not the follow this gist for step by step setup.

To send email from the gmail server you need to allow access for less secure apps in your Google account

	load local data infile 'tfidf.csv' into table tfidf fields terminated by "\|" lines terminated by '\n'(term, tag, count);

	DELIMITER //
	CREATE PROCEDURE tfidf_applier()
	begin
	declare res1 INT;
	set res1 = (select count(distinct tag) from tfidf);

	drop table if exists log_term_table;
	create table log_term_table(term varchar(200), logval decimal(20,5));

	from __future__ import (absolute_import, division, print_function,
	unicode_literals)

	from sqlalchemy import Column, MetaData, Table, create_engine
	from sqlalchemy import String, Integer, Float, BigInteger, DateTime

	from sqlalchemy.schema import DropTable, CreateTable
	from sqlalchemy.orm import scoped_session, sessionmaker
