[ruby-talk:444599] [ANN] tobox 0.7.0 released
by Tiago Cardoso 18 Dec '24

18 Dec '24

The first version of tobox (v0.7.0) has been released. tobox implements the consumer side of the transactional outbox pattern, providing a simple way to configure your event handlers. * https://gitlab.com/honeyryderchuck/tobox * https://microservices.io/patterns/data/transactional-outbox.html tobox executes your handlers in a worker pool. The worker pool can be thread-based (default) or fiber-based. It uses the “SKIP LOCKED” SQL dialect to support concurrent polling for events from the database outbox table. It therefore only supports databases implementing it. As of today, that's: * PostgreSQL 9.5+ * MySQL 8+ * Oracle * Microsoft SQL Server It ships with plugins for sentry, datadog and zeitwerk. The plugin system is itself very simple, so you can add your own custom logic around event processing. It can be used as a background job processor, although it’s best used in tandem with an existing framework. Here are the updates since the last release: ## [0.7.0] - 2024-12-18 ### Features #### `:pg_notify` plugin The `:pg_notify` plugin is introduced, which leverages the PostgreSQL-only `LISTEN/NOTIFY` statements to asynchronously notify workers when there are new events to be processed (instead of regularly polling the database). #### `visibility_column` and `attempts_column` configuration The `visibility_column` configuration (default: `:run_at`) can be used not only to point to a differently named column, it can both point to either a timestamp column (used as a visibility timeout for events) or a boolean column (used to hide events from other transactions); using the latter will also disable exponential backoff in retries. The `attempts_column` configuration (default: `:attempts`) can be used to point to a differently named column, or, when set to `nil`, uncap retries. See when they can be used for in the readme recommendations section. ### Improvements #### fiber pool on async Support was removed for the `fiber_scheduler` gem, which is under-maintained, so the fiber worker pool will use an [async]( https://github.com/socketry/async) scheduler going forward. Functionality and APIs will be the same, but you'll have to add it to your Gemfile. ### Bugfixes * `datadog` integration: environment variables were wrongly named. ### Chore * `mutex_m` usage was removed. ## [0.6.1] - 2024-10-30 ### Improvements When possible, use `UPDATE FROM outbox RETURNING WHERE (SELECT id .... FOR UPDATE SKIP LOCKED` to fetch-and-update events in one go. ## [0.6.0] - 2024-10-25 ### Features #### Batch Events handling It's now possible to handle N events at a time. ```ruby # tobox.rb batch_size 10 # fetching 10 events at a time on("user_created", "user_updated") do |*events| # 10 events at most if events.size == 1 DataLakeService.user_created(events.first) else DataLakeService.batch_users_created(events) end end ``` This also supports raising errors only for a subset of the events which failed processing (more info in the README). ## [0.5.2] - 2024-10-22 ## Bugfixes * prevent `:max_connections` from being overidden. ### Improvements ## [0.5.1] - 2024-09-26 ### Improvements * Refactoring of management of event id which replaces `SELECT id IN (?)` resulting queries with `SELECT id = ?`. * Process shutdown is now more predictable, also in the grace period. * `grace_shutdown_timeout` is a new configuration, by default 5 (seconds).

[ruby-talk:444596] The DCR Kids Programming Language Supports Live GUI Updates
by Andy Maleh 11 Dec '24

11 Dec '24

One of the requests I received at RubyConf 2024 for Glimmer DSL for LibUI (and other Glimmer desktop gems) is providing an editor that can update the GUI live as the programmer types code into it. I have built something like that before for a programming language for kids called DCR actually. https://raw.githubusercontent.com/AndyObtiva/dcr/master/images/dcr-demo.gif Continue reading blog post: https://andymaleh.blogspot.com/2024/12/the-dcr-kids-programming-language.ht… Check out DCR (Draw Color Repeat), which is built in Ruby using Glimmer DSL for SWT: https://github.com/AndyObtiva/dcr

[ruby-talk:444595] Montreal.rb Hack Night Solutions for Hunt The Wampus
by Andy Maleh 09 Dec '24

09 Dec '24

In November and December of 2024, Montreal.rb hosted 2 Ruby Hack Night meetups about building the historic computer game, Hunt The Wampus, which was a text-based adventure game developed by Gregory Yob in 1973. A GitHub repo has been provided with solutions, which include the Ruby code for the Model layer, a desktop GUI View layer, and a Rails Web Frontend View layer: https://andymaleh.blogspot.com/2024/12/montrealrb-hack-night-solutions-for.… https://raw.githubusercontent.com/AndyObtiva/hunt_the_wampus/refs/heads/sol…

[ruby-talk:444594] [ANN] graphics 1.1.2 Released
by Ryan Davis 07 Dec '24

07 Dec '24

graphics version 1.1.2 has been released! * home: <https://github.com/seattlerb/graphics> * rdoc: <http://docs.seattlerb.org/graphics> Graphics provides a simple framework to implement games and/or simulations and is designed to follow mathematical conventions, NOT game programming conventions. Particularly it: * Uses degrees. * Draws in quadrant 1 (0-90 degrees). * Right hand rule: 0 degrees is east, 90 is north, etc. These allow simple things like Trigonometry functions to work as expected. It means that all that stuff you were taught in grade school still work as intended. This makes one less thing you have to adjust when implementing your simulation. Changes: ### 1.1.2 / 2024-12-07 * 1 minor enhancement: * Bumped required ruby version. * 3 bug fixes: * Fixed bad copy/paste in setup script. (havenwood) * Fixed color handling in polygon. * Fixed frozen string literal in examples/editor.rb
