 Topic: Back to School.   Summer is over, it's time to hit the books,  what are you going to brush up on in the next few months?

QOTD: “I applied bootstrap, what more do you want”

• Graphic design history
• Graphic design vs front end dev
• Language learning
• DUO lingo has sad owls

Intermission while I helped to get the kid’s car started

• A case study in interpersonal interactions and work relationships between “Product” and “Engineering” teams

And we will save the topic for another time, since is it mostly unused.

 Topic: Conway’s Game of Life Challenge part 2 what did you learn.

• High school was so long ago (for some of us)
• Conway’s game is one of the exercises at Code Retreat
• Global Day of Code Retreat is coming up in November
• Looking into the possibility of hosting in Grand Rapids
• https://www.coderetreat.org/
• What did we learn
• It takes a little while, especially the first time or the first time after a while
• Talked about some of the trade offs that can be surfaced
• Memory usage for a big grid
• Processing time vs memory usage
• Complexity 
• Talked about micro controllers
• Raspberry pi pico is really fast and really cheap
• Forza LED Strip Tachometer https://www.youtube.com/watch?v=_tIw8-Gl2F4 
• Java script
• this
• is fun, what is the scoping and semantics
• Functional vs OO javascript vs ???
• ??? may be procedural
• Lesson learned: “There is no substitute for Integration Tests”
• again
• This was not on Conway’s game but in real life.

Code & Coffee recap from 8/6/2021

 Topic: Conway’s Game of Life Challenge

• Keeping up with tech
• is important
• or tech will leave you
• Programming is hard: Copy all the elements of an array
• for (m=0; m < len; m++) {
• for (n=0; n < len; ++n) {
• will it work?
• no.
• BOO!
• This was an example problem and fragment of one person’s solution
• This was a rough conversation.
• Sometimes it takes a bit for things to click, sometimes they don’t
• These conversations should be handled gracefully with an eye towards everyone’s future.
• Some people are more wired for programming
• Missed a lot of stuff about containers and networking and latency
• And I was driving Sam so I missed taking notes
• But it was good stuff
• Bruce was talking about Native Spring
• Sounds pretty cool, lots of potential
• Make sure you have tests it sounds like there is some tree shaking going on during the running of the tests and if you don’t use a class in a test it might not notice that you need things compiled in to work.
• Talked about the intersection of computerized processes and how they interact with the real world.
• Do you know what the price is.  Really?
• Introduced the “Conway’s Game of Life” challenge
• Do an implementation
• Bring something to talk about related to the implementation next week
• Or if you won’t be attending, then send your implementation and we will talk about it, just let us know if we should be nice or rip it to shreds.

Code & Coffee recap from 7/30/2021

 Topic: "What are you reading"  60 second review and bring links to share if you are able.

This week we talked about what we are reading or looking forward to reading soon.  I find this to be an expensive topic as it tends to add more to my bookshelf.  Good discussion and lots of variety.

Thomas:

• Segueing into management-is books:
• Drive by Dan Pink
• “this could be four blog posts and two ted talks and were done ;-)”
• But it is still very much worth the read
• Traction
• EOS 
• Effective Java
• 90 rules, did one rule per day
• Site Reliability Engineering
• Next up
• Head First Design Patterns

Carlus:

• Managing the Professional Service Firm
• Carlus’s review: “I am leaning more on the Manager style books right now.  Here is one that I am actively working on.  First part is excellent....later chapters most people find a little more dry....but there are still some great nuggets”
• https://www.amazon.com/Managing-Professional-Service-David-Maister/dp/0684834316/ref=sxts_rp_s1_0?crid=18EAPSCT2P3JG&cv_ct_cx=managing+the+professional+service+firm&dchild=1&keywords=managing+the+professional+service+firm&pd_rd_i=0684834316&pd_rd_r=8c66ee42-e588-4ad4-9d19-cd9adda23081&pd_rd_w=H7CE4&pd_rd_wg=lZwjR&pf_rd_p=c6bde456-f877-4246-800f-44405f638777&pf_rd_r=W26W22AGVHF0WHJS1JAK&psc=1&qid=1627649867&sprefix=managing+services%2Caps%2C155&sr=1-1-f0029781-b79b-4b60-9cb0-eeda4dea34d6

Hoppe:

• In progress:
• Better Decisions, Fewer Regrets: 5 Questions to Help You Determine Your Next
• Mostly it is about 5 questions that can help determine how and why you are making decisions
• https://smile.amazon.com/gp/product/B08657CF4L/ref=ppx_yo_dt_b_d_asin_title_o00aud_?ie=UTF8&psc=1
• Growing Object-Oriented Software, Guided by Tests
• Good stuff, some seems very fundamentally… but I think that is the point.
• There is a very good description and definition of the different types of tests that I am liking
• Unit test: A test that only tests code under your control
• Integration test: A test that tests a thin layer of code you control against external code
• Acceptance test: A business facing test that presents a piece of the application and show that it meets a business need.
• Typically is an end to end test, there may be reasons for it not to be but most of the time it will be.
• https://learning.oreilly.com/library/view/growing-object-oriented-software/9780321574442/
• On deck:
• Software Design for Flexibility: How to Avoid Programming Yourself into a Corner
• https://mitpress.mit.edu/books/software-design-flexibility
• This is related to and perhaps a next step after Structured Interpretation of Computer Programs which is also on deck and should likely precede this:
• https://mitpress.mit.edu/sites/default/files/sicp/index.html
• Continuous Architecture in Practice: Software Architecture in the Age of Agility and DevOps
• This is a new release and looks to be very practical application stuff, looking forward to it.
• https://learning.oreilly.com/library/view/continuous-architecture-in/9780136523796/

Does this look interesting to you?  Let me know in the comments and I will get you invited to the slack channel where we organize the group.
