Lisp (LISt Processing language) was developed at MIT in 1959 Lisp is considered the first functional programming language and was extensively used in artifical intelligence. (format t "Hello, World!")

A service mesh is a configurable framework that allowa you to connect, control, observe and secure microservices. It removes these responsabilities from you application logic, delegating them to the service mesh.

Some important root subdirectories in a tweet - /media: mount removable media - /mnt: user temp mounting - /sys: contains device & system info - /sbin: system executables - /tmp: temporary files - /usr: the bulk of the Linux system - /var: programs save runtime info here

What happens when you run ls in your terminal? The shell calls fork() to create a copy of the shell process This copy calls exec(ls) to run ls This is how new processes are created fork and exec are system calls - ways for your programs to interact with the kernel

90% of programming is saying WTF!!!

To be a developer you have to be able to endure long and intense periods of feeling stupid on a consistent basis.

"In my experience, one of the most significant problems in software development is assuming. If you assume a method will passed the right parameter value, the method will fail." - Paul M. Duvall

"Good" today is usually better than "perfect" tomorrow

3 JavaScript interview questions What's the difference between == and ===? How to evaluate multiple expressions in one line? What is Functional Programming and what are the features of JavaScript that makes it a candidate as a functional language?

"How do we convince people that in programming simplicity and clarity —in short: what mathematicians call "elegance"— are not a dispensable luxury, but a crucial matter that decides between success and failure?" - Edsger W. Dijkstra

Tip for interviews in Python: To iterate over a list and also know the index of the current item, use enumerate for idx, val in enumerate(my_array): do_something(idx) ... You can supply a second parameter to enumerate to specify the number from (defaults to zero)

Lines of code are only worth counting when you're deleting them

GCP vs AWS terminology - Both use Region as a group of data centers close to one another - Zone vs Availability Zone: individual data centers. Several per region - Points Of Presence: Both use them to provide CDN services in a similar way

Even "simple" things, like synchronizing clocks in different nodes in a distributed system, is more complex that it seems. Distributed systems are the quantum mechanics of software design.

Science is a differential equation Religion is a boundary condition - Alan Turing

I know a joke about UDP but I don't know if you would get it

"The code you write makes you a programmer. The code you delete makes you a good one. The code you don't have to write makes you a great one." - Mario Fusco

"Great things are not done by impulse, but by a series of small things brought together." - Vincent van Gogh

JavaScript has a single type for numbers, represented as 64-bit floating point Integers are also represented using this same type

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