"Starting a startup is hard, but having a 9 to 5 job is hard too, and in some ways a worse kind of hard." - Paul Graham

AWS 101 AWS physical infrastructure is located in Regions: separate geographic areas. Each region has 2 o more isolated locations known as Availability Zones. By default, resources aren’t replicated across regions.

In 1964, BASIC was developed by John Khomeini and Thomas Kurtz The idea was to allow students without a strong background in mathematics to be able to effectively use computers BASIC stands for Beginners' All-purpose Symbolic Instruction Code PRINT "Hello, world!"

2 Different approaches for DB storage engines: - Log based: writes are appended to a log file. Ex: Cassandra, HBase - In place updates. Ex: B-trees (used both in relational and NoSQL dbs)

"Talk is cheap. Show me the code." - Linus Torvalds

Design patterns in 1 tweet State: Change the behaviour of an object when its state changes Ex: fan controller. When changing state from level 1 to 2, it increases the rotation speed.

"I have always found that plans are useless, but planning is indispensable." - Dwight D. Eisenhower

Language agnostic coding tips: - Avoid "magic constants" - Avoid uninitialized variables - Make name lenghts proportional to their scope - Name an object to reflect its meaning - Postpone variable declaration as much as you can

Simple code to solve a complex problem >>> Complex code to solve a simple problem Focus on the impact of your work, not to "look smart" .

Resume tips - Less is more. 2 pages max - Avoid exaggerating. You can get grilled on anything you put on your resume - Focus on what you did. Not your team or your company - Implemented, coded, launched, led, designed >> Helped, contributed, participated

2 common bugs: 1. Uninitialized variables. Ex: int min(int *A, int n) { int sol; for (int i=0; i Compiler would complain

The more bizarre the behavior, the more stupid the mistake.

Do not considered thar you've learned a new concept: - Language feature - Algorithm - Data structure - Design pattern - DB technology - Etc until you are able to explain it with your own words.

In a derived class, how do you call the parent constructor (in Java)? Using the "super" function: this.super(...) Interestingly, in Python the function is also called super

"The only way to learn a new programming language is by writing programs in it." - Dennis Ritchie

When fixing a bug, the most important thing is a reliable procedure to reproduce the problem. Try to trigget the issue manually. Then write a test that fails. Only then, start changing your code.

Labels are key-value pairs you can use to organize your resources in GCP. Once you attach a label to a resource (for instance, to a virtual machine), you can filter based on that label. This is useful also to break down your bills by labels.

Binary search trees (height h, N nodes): - Insert and contains operations are O(h) - Elements in order: find min/max in O(h) - Efficient range queries Sorted inputs make them look like a linked list o(h) -> O(N) Balanced BST: AVL, red-black,... o(h) -> log(N)

Storage Transfer Service (STS), a service that imports data to a GCS bucket from: - An AWS S3 bucket - A resource that can be accessed through HTTP(S) - Another GCS bucket For huge amounts of data consider Data Transfer Appliance: ship your data to a Google facility.

Without putting the things you read into action in a real project, you will forget soon.
