Call for Participation

The Erlang, Elixir & Friends Devroom will take place in person at FOSDEM on Sunday, 5th February 2023.

We invite authors to submit original, high-quality work with sufficient background material to be clear to the BEAM community.

Topics

We welcome any talk proposals about BEAM-related projects. Topics of interest include, but are not limited to:

rbino

input_stream =
  Stream.iterate(%{x: 0, y: :random.uniform() * 100}, fn %{x: x} ->
    %{x: x + 1, y: :random.uniform() * 100}
  end)
  
# Take 20 samples output samples after downsampling by 2.3
# The 20 output samples will correspond to ~ 20 * 2.3 input samples
output_samples =
  ExLTTB.Stream.downsample(input_stream, 2.3)
  |> Enum.take(20)

# Downsample a list of data of arbitrary shape
input_samples =
  for x <- 1..1000 do
    %{nested: %{timestamp: x},
      data: :random.uniform() * 100,
      untouched_other_key: :random.uniform() * 3
    }
  end

sample_to_x_fun = fn sample -> sample[:nested][:timestamp] end

rbino

# Downsample a list of data in the default shape of %{x: x, y: y}
input_samples = for x <- 1..1000, do: %{x: x, y: :random.uniform() * 100}

# 50 output samples
output_samples = ExLTTB.downsample_to(input_samples, 50)
