Note: these are pretty rough notes I made for my team on the fly as I was reading through some pages. Some could be mildly inaccurate but hopefully not terribly so. I might resort to convenient fiction & simplification sometimes.

My top contenders, mostly based on popularity / community etc:

• Angular
• Backbone
• React
• Ember

Mostly about MVC (or derivatives, MVP / MVVM).

2018 Update: Easiest option is Justin's repo and image

Just run this from your Mac terminal and it'll drop you in a container with full permissions on the Moby VM. This also works for Docker for Windows for getting in Moby Linux VM (doesn't work for Windows Containers).

docker run -it --rm --privileged --pid=host justincormack/nsenter1

set -e, -u, -o pipefail

The "set" lines These lines deliberately cause your script to fail. Wait, what? Believe me, this is a good thing. With these settings, certain common errors will cause the script to immediately fail, explicitly and loudly. Otherwise, you can get hidden bugs that are discovered only when they blow up in production.

set -euo pipefail is short for:

set -e
set -u

Microservices Lessons Learned

"People try to copy Netflix, but they can only copy what they see. They copy the results, not the process" - A.Cockcroft - AWS

Many case studies about migrating to microservices are about big organizations like Netflix, Google, Zalando, Facebook, Etsy, etc. What about smaller companies?

Each journey is different for every organization: what works for an org does not work for another. No golden-rule.

There are different circumstances:

Rodrigue Schaefer: From monolith to microservices about some of the challenges of Zalando's transition from monolith to microservices (microXchg 2016)

Zalando history

• 2008 started with a POC with magento => starts fine but does not scale very well

• 2010 couldn't handle the raising load and traffic with magento

• => so in 3 months they build their own system, based on Java, Spring, Postgres DB (a monolithic application)

### README
# This Python scripts exports all the OneNote notebooks linked to your Microsoft account to HTML files.

## Output
# The notebooks will each become a subdirectory of the `output` folder, with further subdirectories
# for the sections within each notebook and the pages within each section. Each page is a directory
# containing the HTML file `main.html` and two directories `images` and `attachments` (if necessary)
# for the images and attachments. Any sub-pages will be subdirectories within this one.
