Shows how to sign and verify HTTP requests with Elixir. This is useful for webhooks and communications between servers on the Web.

Thus, making sure that the token is being used by the same web browser used to authenticate in the first place? Note: I am using Guardian.

cuckoo_filter is a high-performance, concurrent, and mutable Cuckoo Filter implemented using atomics for Erlang and Elixir. A Cuckoo Filter is a space-efficient probabilistic data structure for approximated set-membership queries. It can be used to test whether an element is a member of a set in constant time with a low rate of false positives. By using erlang atomics we have fast and concurrent access for read and write operations. It is implemented in erlang so you can use it in both erlang...

Not really, you can run ICMP socket as a regular user if your user ID is within sysctl net.ipv4.ping_group_range. However that will require you to use datagram socket instead of raw socket: {:ok, socket} = :socket.open(:inet, :dgram, :icmp) It also has slightly reduced API, as for example on Linux you cannot specify id and seq fields for ICMP packet, as these will be always set for you. There is library that I have created in the past that provide slightly higher API for ICMP sockets (still q...

We make a small line-oriented TCP socket server to explore how sockets and some manual process management works in Elixir.

In this post, we'll explore how to use Oban, a robust background job processing system for Elixir.

After working for years on different organizations, one common theme is scheduling background jobs.
