Multi-thread processing in Go

Threads

A thread is the smallest unit of processing that an OS can perform. The default size of a thread in a Linux/x86-32 machine is 2MB

Threads can be :

1. Concurrent - Two or more threads can start, run and complete in overlapping periods.
2. Parallel - The same task can be executed multiple times at once.

Chess Training

My current goals:

1. Go through my checklist before EVERY move.
2. Stop playing hope chess: if you can find a single weakness in an idea, abandon it and find a new idea.

The Checklist

GROKKING NOTES

I liked the way Grokking the coding interview organized problems into learnable patterns. However, the course is expensive and the majority of the time the problems are copy-pasted from leetcode. As the explanations on leetcode are usually just as good, the course really boils down to being a glorified curated list of leetcode problems.

So below I made a list of leetcode problems that are as close to grokking problems as possible.

Pattern: Sliding Window

• https://leetcode.com/problems/maximum-subarray/ # Close enough
• https://leetcode.com/problems/minimum-size-subarray-sum/

/*
* Why Protocol Buffers?
* Protocol buffers are Google's language-neutral, platform-neutral, extensible mechanism for serializing structured data – think XML, but smaller, faster, and simpler.
* You define how you want your data to be structured once, then you can use special generated source code to easily write and read your structured data to and from a variety of data streams and using a variety of languages.
* Protocol Buffers are Schema Of Messages. They are language agnostic.

System Design Cheatsheet

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

Basic Steps

1. 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?

Kartones

• pip install pystatsd
• python -c 'import pystatsd; pystatsd.Server(debug=True).serve()'
• Config is localhost:8125
