My Thoughts on Bradfield

I've been asked by several people over time about my experience with the classes offered by Bradfield, and thought that I should save some future keystrokes by writing up a short gist for future reference. Hopefully this gist will be useful for others who are considering Bradfield and wondering it is worth it. My intended audience is primarily Launch School students who have completed the Core program and likely also Capstone, but the majority of this gist will be applicable to anyone who is a working/experienced software engineer.

Since late 2019, I've taken 4 short courses from the Bradfield School of Computer Science and in 2021 I enrolled in their Computer Science Intensive (CSI) program¹. Overall, I've found the courses and CSI to be an excellent opportunity to grown my technical skills and broaden my knowledge of CS topics.

The courses I completed were:

Computer Architecture: The Hardware/Software Interface

Set up remote debugging in dockerized Tomcat

Start Container, stock tomcat 8.5 in this example

$  docker run \
    -eJPDA_OPTS="-agentlib:jdwp=transport=dt_socket,address=5005,server=y,suspend=n" \
    -p8080:8080 \

Distributed Systems

Lesson 1 - Introduction

Systems today are generally distributed, both in-house and third-party systems
Stream processing is batch processing but in smaller increments, it isn't real-time, but is quick
Project, work as pre and post work
Reliability
Scalability
Maintainability
