On today's episode, Elixir Wizards Owen Bickford and Dan Ivovich compare notes on building web applications with Elixir and the Phoenix Framework versus Ruby on Rails. They discuss the history of both frameworks, key differences in architecture and approach, and deciding which programming language to use when starting a project. Both Phoenix and Rails are robust frameworks that enable developers to build high-quality web apps—Phoenix leverages functional programming in Elixir and Erlang's networking for real-time communication. Rails follows object-oriented principles and has a vast ecosystem of plug-ins. For data-heavy CRUD apps, Phoenix's immutable data pipelines provide some advantages. Developers can build great web apps with either Phoenix or Rails. Phoenix may have a slight edge for new projects based on its functional approach, built-in real-time features like LiveView, and ability to scale efficiently. But, choosing the right tech stack depends heavily on the app's specific requirements and the team's existing skills. Topics discussed in this episode: History and evolution of Phoenix Framework and Ruby on Rails Default project structure and code organization preferences in each framework Comparing object-oriented vs functional programming paradigms CRUD app development and interaction with databases Live reloading capabilities in Phoenix LiveView vs Rails Turbolinks Leveraging WebSockets for real-time UI updates Testing frameworks like RSpec, Cucumber, Wallaby, and Capybara Dependency management and size of standard libraries Scalability and distribution across nodes Readability and approachability of object-oriented code Immutability and data pipelines in functional programming Types, specs, and static analysis with Dialyzer Monkey patching in Ruby vs extensible core language in Elixir Factors to consider when choosing between frameworks Experience training new developers on Phoenix and Rails Community influences on coding styles Real-world project examples and refactoring approaches Deployment and dev ops differences Popularity and adoption curves of both frameworks Ongoing research into improving Phoenix and Rails Links Mentioned in this Episode: SmartLogic.io (https://smartlogic.io/) Dan's LinkedIn (https://www.linkedin.com/in/divovich/) Owen's LinkedIn (https://www.linkedin.com/in/owen-bickford-8b6b1523a/) Ruby https://www.ruby-lang.org/en/ Rails https://rubyonrails.org/ Sams Teach Yourself Ruby in 21 Days (https://www.overdrive.com/media/56304/sams-teach-yourself-ruby-in-21-days) Learn Ruby in 7 Days (https://www.thriftbooks.com/w/learn-ruby-in-7-days---color-print---ruby-tutorial-for-guaranteed-quick-learning-ruby-guide-with-many-practical-examples-this-ruby-programming-book--to-build-real-life-software-projects/18539364/#edition=19727339&idiq=25678249) Build Your Own Ruby on Rails Web Applications (https://www.thriftbooks.com/w/build-your-own-ruby-on-rails-web-applications_patrick-lenz/725256/item/2315989/?utm_source=google&utm_medium=cpc&utm_campaign=low_vol_backlist_standard_shopping_customer_acquisition&utm_adgroup=&utm_term=&utm_content=593118743925&gad_source=1&gclid=CjwKCAiA1MCrBhAoEiwAC2d64aQyFawuU3znN0VFgGyjR0I-0vrXlseIvht0QPOqx4DjKjdpgjCMZhoC6PcQAvD_BwE#idiq=2315989&edition=3380836) Django https://github.com/django Sidekiq https://github.com/sidekiq Kafka https://kafka.apache.org/ Phoenix Framework https://www.phoenixframework.org/ Phoenix LiveView https://hexdocs.pm/phoenixliveview/Phoenix.LiveView.html#content Flask https://flask.palletsprojects.com/en/3.0.x/ WebSockets API https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API WebSocket connection for Phoenix https://github.com/phoenixframework/websock Morph Dom https://github.com/patrick-steele-idem/morphdom Turbolinks https://github.com/turbolinks Ecto https://github.com/elixir-ecto Capybara Testing Framework https://teamcapybara.github.io/capybara/ Wallaby Testing Framework https://wallabyjs.com/ Cucumber Testing Framework https://cucumber.io/ RSpec https://rspec.info/

Brian #1: Awesome pytest speedup Neyts Zupan A checklist of best practices to speed up your pytest suite. as a talk at Plone NAMUR 2022 Measure first Then make sure (all items have explanations) Hardware is fast use a faster computer also try a self-hosted runner seriously, a dedicated computer (or a few) for making test runs faster might be worth it. CI resources are usually slower in cloud than local, and even expensive VM farms are often slower. Try local Collection is fast utilize norecursedirs and specifying the location of the tests, either on the command line or with testpaths PYTHONDONTWRITEBYTECODE=1 is set might help Built-in pytest plugins are disabled try -p no:pastebin -p no:nose -p no:doctest Only a subset of tests are executed Especially when developing or debugging, run a subset and skip the slow tests. Network access is disabled pytest-socket can make sure of that Disk access is disabled interesting idea Database access is optimized great discussion here, including using truncate and rollback. Tests run in parallel pytest-xdist or similar Then keep them fast monitor test speed Michael #2: Strive to travel without a laptop Prompt from Panic for SSH on iThings github.dev for an editor on iPad Push to branch for continuous deployment BTW, Apple could just make M1 iPads boot to macOS rather than chase silly multi windowing systems (stage manager, etc, etc) Brian #3: Some fun tools from the previous testing article hyperfine for timing the whole suite pytest --``durations 10 for finding test times of slowest 10 tests leave the 10 off to find times of everything, sorted pyinstrument for profiling with nice tree structures and how to use it with pytest pytest-socket disables network calls with --disable-socket, helping to find tests that use network calls. pyfakefs, a fake file system that mocks the Python file system modules. “Using pyfakefs, your tests operate on a fake file system in memory without touching the real disk.” BlueRacer.io Michael #4: Refurb A tool for refurbishing and modernizing Python codebases Think of it as suggesting the pythonic line of code. A little sampling of what I got on Talk Python Training file.py:186:25 [FURB106]: Replace x.replace("t", " ") with x.expandtabs(1) file.py:128:17 [FURB131]: Replace del x[y] with x.pop(y) file.py:103:17 [FURB131]: Replace del x[y] with x.pop(y) file.py:112:39 [FURB109]: Replace not in [x, y, z] with not in (x, y, z) file.py:45:5 [FURB131]: Replace del x[y] with x.pop(y) file.py:81:21 [FURB131]: Replace del x[y] with x.pop(y) file.py:143:9 [FURB131]: Replace del x[y] with x.pop(y) file.py:8:50 [FURB123]: Replace list(x) with x.copy() You don't always want the change, can suppress the recommendation with either a CLI flag or comment.

Link to bioRxiv paper: http://biorxiv.org/cgi/content/short/2020.08.21.261966v1?rss=1 Authors: Han, H. Abstract: BayesFactorFMRI is a tool developed with R and Python to allow neuroimaging researchers to conduct Bayesian second-level analysis and Bayesian meta-analysis of fMRI image data with multiprocessing. This tool expedites computationally intensive Bayesian fMRI analysis through multiprocessing. Its GUI allows researchers who are not experts in computer programming to feasibly perform Bayesian fMRI analysis. BayesFactorFMRI is available via Zenodo and GitHub for download. It would be widely reused by neuroimaging researchers who intend to analyse their fMRI data with Bayesian analysis with better sensitivity compared with classical analysis while improving performance by distributing analysis tasks into multiple processors.

William Leslie - OmniTrend Universe William Bill Leslie was one of the authors of Omnitrend's Universe; a science fiction space trading and combat game.  The first version was programmed in valFORTH on an Atari 800, based on a board game created by Bill. It was Omnitrend's first game and was released in 1983. There were versions of Universe for the Atari 8-bit, Apple II and IBM computers. Bill was also involved in the development of the sequels Universe 2 and Universe 3, and of Breach, a turn-based tactical squad combat game. This interview took place on Jan. 7, 2017.
