If you're interested in the Ruby language too, check out this PoC gem for an "operator-less" syntax for pipe operations using regular blocks/expressions like every other Ruby DSL.

https://github.com/lendinghome/pipe_operator#-pipe_operator

  "https://api.github.com/repos/ruby/ruby".pipe do
    URI.parse
    Net::HTTP.get
    JSON.parse.fetch("stargazers_count")
    yield_self { |n| "Ruby has #{n} stars" }
    Kernel.puts
  end
  #=> Ruby has 15120 stars

  [9, 64].map(&Math.pipe.sqrt)           #=> [3.0, 8.0]
  [9, 64].map(&Math.pipe.sqrt.to_i.to_s) #=> ["3", "8"]

Check out this proof of concept gem to perform pipe operations in Ruby using block expressions:

https://github.com/lendinghome/pipe_operator#-pipe_operator

  "https://api.github.com/repos/ruby/ruby".pipe do
    URI.parse
    Net::HTTP.get
    JSON.parse.fetch("stargazers_count")
    yield_self { |n| "Ruby has #{n} stars" }
    Kernel.puts
  end
  #=> Ruby has 15120 stars

As a Kafka alternative, has anyone attempted to use PostgreSQL logical replication with table partitioning for async service communication?

Proof of concept (with diagrams in the comments): https://gist.github.com/shuber/8e53d42d0de40e90edaf4fb182b59...

Services would commit messages to their own databases along with the rest of their data (with the same transactional guarantees) and then messages are "realtime" replicated (with all of its features and guarantees) to the receiving service's database where their workers (e.g. https://github.com/que-rb/que, skip locked polling, etc) are waiting to respond by inserting messages into their database to be replicated back.

Throw in a trigger to automatically acknowledge/cleanup/notify messages and I think we've got something that resembles a queue? Maybe make that same trigger match incoming messages against a "routes" table (based on message type, certain JSON schemas in the payload, etc) and write matches to the que-rb jobs table instead for some kind of distributed/replicated work queue hybrid?

I'm looking to poke holes in this concept before sinking anymore time exploring the idea. Any feedback/warnings/concerns would be much appreciated, thanks for your time!

Definitely agree regarding the strange semantics recently like the pipeline[0] or `.:` method reference[1] operators. I do think those kind of functional features would be handy if they behaved correctly and had a more Ruby-like syntax instead of introducing foreign looking operators.

Luckily this new pattern matching feature appears to behave like expected and feels pretty natural - just a new `in` keyword and some variable binding syntax to familiarize ourselves with (which we already kind of use with statements like `rescue`).

Awhile back we experimented with an alternative Ruby pipe operator proof of concept[2] that is "operator-less" and looks just like regular old Ruby blocks with method calls inside of it. Maybe there's still a chance for something like this now that those other implementations have been reverted!

  # regular inverted method calls
  JSON.parse(Net::HTTP.get(URI.parse(url)))

  # could be written left to right
  url.pipe { URI.parse; Net::HTTP.get; JSON.parse }

  # or top to bottom for even more clarity
  url.pipe do
    URI.parse
    Net::HTTP.get
    JSON.parse
  end

Elixir/Unix style pipe operations in Ruby! https://github.com/LendingHome/pipe_operator

That's what it's doing, arguments are preserved:

    # don't really know what IO.inspect is doing
    # but guessing something like this?
    def IO.inspect(value, label:)
      puts "#{label}: #{value.inspect}"
      value
    end

    value.pipe do
      IO.inspect(label: "A")
      do_something
      IO.inspect(label: "B")
      do_something_else
      IO.inspect(label: "C")
    end

Thanks! Agreed it feels like a good fit for Ruby as well!

RE the pattern matching stuff I think the destructuring concept could be applied to look something like:

    def div(*args)
      case args
      when Pattern{[a, 0]} then [:error, "can't divide by 0"]
      when Pattern{[a, 1]} then [:ok, Pattern.last.a]
      when Pattern{[0, b]} then [:ok, 0]
      when Pattern{[a, b]} then [:ok, Pattern.last.a / Pattern.last.b]
      end
    end

    def something(object)
      case object
      when Pattern{a[b, c]} then [:ok, Pattern.last.b + Pattern.last.c]
      else [:error, "a didn't contain b and c"]
      end
    end

Thanks for your feedback!

Check out this other proof of concept demonstrating ES6 style object destructuring in Ruby:

https://github.com/lendingHome/destruct

I think this same type of concept could be applied to port Elixir style pattern matching as well e.g.

    data = {
      name: "John Smith",
      age: 35,
      prefs: {
        lang: "en",
        tz: "UTC",
      }
    }
    
    User = Pattern { name age prefs[lang] }
    
    user = User =~ data
    user.name
    user.age
    user.lang
    
    [data].map(&User)
    
    case object
    when Pattern { some attrs[:nested][real][deep, fields] }
      Pattern!.some
      Pattern!.real
      Pattern!.deep
      Pattern!.fields
      Pattern!.nested #=> NoMethodError
    end
    
    # or define "locals" by defining temporary methods on
    # the block receiver when the "then" block is evaluated
    case object
    when Pattern { some nested[data] }.then do
      puts some
      puts data
    end

What are some good resources to learn more about the inner workings of text editors or building one from scratch? So far I've found and enjoyed reading/watching the resources below and would love to learn more.

Wow that sounds awesome! Are there any estimates of when this will be an open beta for everyone? Very excited to try it out!

Docker ID: shuber

Nice, we had a similar issue which is why we decided to merge the repositories. It makes sharing code, extracting shared dependencies, and reviewing PRs so much easier when you can see changes across all projects in one diff!

You can absolutely filter the history from some directories by specifying a script to run after the repositories have been cloned. In your monolith.yml you can add something like:

  # Optional list of commands to run right after
  # all of the repositories above have been cloned.
  #
  # These are handy for things like rewriting history
  # to remove large unused files or sensitive information.
  after_clone:
    - ./remove_large_assets

After the files are filtered, the monolith repository will be generated without all that junk that was bloating your git history.

Misc tools to make development more efficient:

https://github.com/shuber/owners - Take ownership of your code! Knowing who owns a project or section of a code base is very helpful when asking questions or requesting feedback. This gem allows developers to define OWNERS files throughout their repository to provide a human and machine readable way to determine who the maintainers are for specific files of code.

https://github.com/shuber/monolith - Generate a monolithic repository for a set of git repositories!

https://github.com/shuber/tmux-git - Display git information in your TMUX status lines! Plays real nicely with vim-promiscuous.

https://github.com/shuber/vim-promiscuous - Instant context switching built on git and vim sessions! It basically takes a snapshot of the following and let's you rollback to previous states:

- All of your vim tabs, buffers, splits, and folds along with their sizes and positions

- The location of your cursor for each buffer

- The actively selected tab/buffer

- Your undo history (each branch's undo history is saved separately)

- Your git stage with all tracked/untracked files and staged/unstaged hunks

I have a similar remapping of Caps:

  * When I tap Caps, it's `<esc>`
  * When I hold Caps OR hit it in combination with any other key, it's `<ctrl>`

Projects like these are awesome learning experiences. I've been working on something similar (rubyisms in php) but in pure php - https://github.com/shuber/phuby

  * mixins
  * classes are objects
  * eigenclasses
  * method_missing, respond_to, respond_to_missing, send, super
  * splat
  * extended, included, inherited callbacks

I've been happy using Google's simple bookmarking service: http://google.com/bookmarks

I bet this project wont harm you inside: http://github.com/huberry/phuby

That's a good idea, I'll throw a bunch of samples up there. Now, I need to figure out how I should display a tag list or cloud on the homepage to navigate. Probably should make a little "syntax help" link when creating madlib stories too.

Weird, I can't reproduce that inquiry error and Hoptoad didn't catch anything. Let me know if you run into that again.

Thanks for your feedback and contribution!

http://madlibber.com/ - Anonymous user generated madlibs. I can't stop working on this [adjective] app!

http://webchiever.com/ - Web achievements

http://inquiryapp.com/ - Hosted FAQs for your apps

I couldn't find any other sites that allowed you to specify your own prompts instead of making you choose from a list like "noun", "adjective", etc. So, I decided to take a crack at it for fun.

It also supports backreferences, and doesn't look all dated like most of the other madlib sites.

or cannabisseur (see my other comment)

Awesome, I had this same idea recently. I wanted to call it Cannabisseur and have the logo be a smug cartoony guy like the reviewer in Ratatouille, but smoking a joint or something.

I just didn't know enough about cannabis to really follow thru with it. Plus I came across http://nugporn.com/ and figured there were other strain reviewing sites like it.

It really depends on what kind of badges/achievements are created.

We definitely wouldn't want anything like "submitted 10 posts to HN", but something like "submitted the most popular comment in an article" might be cool.

Could you clarify what you meant by this? When a new game is created, the developers of the game will be responsible for defining the achievements in webchiever.
