Python vs. C/C++ in embedded systems... The C/C++ programming languages dominate embedded systems programming, though they have a number of disadvantages. Python, on the other hand, has many strengths that make it a great language for embedded systems. Let's look at the pros and cons of each, and why you should consider Python for embedded programming.

federation v0.12.0 released

#Python #federation now includes more support for the upcoming #diaspora protocol breaking changes and also includes support for the new Contact entity type. Additionally, legacy sharing/following Request entity has fixes.

Repository: https://github.com/jaywink/federation


Backwards incompatible changes

  • Removed exception class NoHeaderInMessageError. New style Diaspora protocol does not have a custom header in the Salmon magic envelope and thus there is no need to raise this anywhere.


  • New style Diaspora public payloads are now supported (see here). Old style payloads are still supported. Payloads are also still sent out old style.
  • Add new Follow base entity and support for the new Diaspora "contact" payload. The simple Follow maps to Diaspora contact entity with following/sharing both true or false. Sharing as a separate concept is not currently supported.
  • Added _receiving_guid to all entities. This is filled with user.guid if user is passed to federation.inbound.handle_receive and it has a guid. Normally in for example Diaspora, this will always be done in private payloads.


  • Legacy Diaspora retraction of sharing/following is now supported correctly. The end result is a DiasporaRetraction for entity type Profile. Since the payload doesn't contain the receiving user for a sharing/following retraction in legacy Diaspora protocol, we store the guid of the user in the entity as _receiving_guid, assuming it was passed in for processing.

There is a prejudice among many that GNU Emacs is a very difficult tool to get used to. This blog will surely help those who work on Python to start using Emacs with minimum efforts.

Python for JavaScript Developers

So recently I began working at a little startup in New York City by the name of Underdog.io, where I discovered that they had a back-end written primarily in Python, a language that I had very little previous exposure to.

While I was hired primarily for my experience with JavaScript and React, the small size of our team means that I frequently have to delve into all parts of the codebase in order to ship a feature. So I had to get well acquainted with Python, very fast.

Unfortunately, I had a hard time finding good resources for learning Python that weren't targeted to people who haven't programmed before. I already knew how to program and am familiar with other languages, I just needed to learn the syntax and paradigms of this one specific programming language, Python.

That's where this blog post comes in. To serve as a quick guide for JavaScript developers who want to get up to speed quickly with Python, but without having to learn what declaring a variable means or what a function is.

federation 0.11.0 released

Federation is a #Python library for abstracting #federated #social network protocols through one API. Currently #Diaspora is supported for status messages, comments and likes + all the signing and discovery related parts. Plan is to start working on #ActivityPub support in the next few months.

If you would like to participate or want to talk about the library, pop into IRC FreeNode #python-federation or join the Gitter chatroom.

Release on GitHub.

Release notes

Backwards incompatible changes

Diaspora protocol support added for comment and like relayable types. On inbound payloads the signature included in the payload will be verified against the sender public key. A failed verification will raise SignatureVerificationError. For outbound entities, the author private key will be used to add a signature to the payload.

This introduces some backwards incompatible changes to the way entities are processed. Diaspora entity mappers get_outbound_entity and entity utilities get_full_xml_representation now requires the author private_key as a parameter. This is required to sign outgoing Comment and Reaction (like) entities.

Additionally, Diaspora entity mappers message_to_objects and element_to_objects now take an optional sender_key_fetcher parameter. This must be a function that when called with the sender handle will return the sender public key. This allows using locally cached public keys instead of fetching them as needed. NOTE! If the function is not given, each processed payload will fetch the public key over the network.

A failed payload signature verification now raises a SignatureVerificationError instead of a less specific AssertionError.


  • Three new attributes added to entities.
    • Add protocol name to all entities to attribute _source_protocol. This might be useful for applications to know which protocol payload the entity was created from once multiple protocols are implemented.
    • Add source payload object to the entity at _source_object when processing it.
    • Add sender public key to the entity at _sender_key, but only if it was used for validating signatures.
  • Add support for the new Diaspora payload properties coming in the next protocol version. Old XML payloads are and will be still supported.
  • DiasporaComment and DiasporaLike will get the order of elements in the XML payload as a list in xml_tags. For implementers who want to recreate payloads for these relayables, this list should be saved for later use.
  • High level federation.outbound.handle_send helper function now allows sending entities to a list of recipients without having to deal with payload creation or caring about the protocol (in preparation of being a multi-protocol library).
    • The function takes three parameters, entity that will be sent, from_user that is sending (note, not necessarely authoring, this user will be used to sign the payload for Diaspora for example) and a list of recipients as tuples of recipient handle/domain and optionally protocol. In the future, if protocol is not given, it will be guessed from the recipient handle, and if necessary a network lookup will be made to see what protocols the receiving identity supports.
    • Payloads will be delivered to each receiver only once. Currently only public messages are supported through this helper, so multiple recipients on a single domain will cause only one delivery.


  • Refactor processing of Diaspora payload XML into entities. Diaspora protocol is dropping the <XML><post></post></XML> wrapper for the payloads. Payloads with the wrapper will still be parsed as before.
