EdgeRank and Content Filtering

Facebook has gotten a lot of press recently over its "EdgeRank" feature. This is basically a filter that sits between you and your friends. Facebook decides what to allow through the filter so that you can see it.  Current estimates are that you only see about 15% of the posts made by your friends. How and why they do this are interesting topics. It seems mostly to be a way to get advertisers to pay more money to get in your face. There's also a claim that seeing all posts and activities would quickly get tedious and therefore you should only be able to see stuff that's "interesting". Since Facebook knows you so well, they're evidently able to decide without a doubt what you'll find "interesting". They don't need to ask you. 

Regardless, wasn't the point of "social networking" so that you could communicate with your friends? A service which claims to provide this, yet somewhat arbitrarily blocks communication between you and your friends would seem to be an anachronism. It kind of takes the "social" out of "social networking" if you're just sending your posts into space and all your friends are prevented from seeing them.

In a world where you have lots of incoming information streams from lots of different sources, you really do need a way to "cut to the chase" and quickly locate information of relevance. This could be in the form of search tools and the ability to view specific streams from your catalogue - rather than the entire firehose.

Here on the free web, the concept of a communications service deciding what communications to allow is an alien and very strange concept.  We think this should be in your hands, under your control. Actually we think that all your online activities should be under your control - so you don't appear in one of your friends' pages pitching vacation packages and toiletries without your knowledge. 

Friendica lets you decide what and how much to see. We've got lots of different "search modes" on your stream to slice and dice the firehose any way you desire. Our next generation project ("Red") adds an entirely new dimension to this - allowing you to "zoom in and zoom out" from your close friends to your most distant acquaintances dynamically.

Is the free web a good match for you? I can't say. You could ask your friends, but chances are they won't ever see the question.


Until next time, this is Commander Zot - saying over and out.



Pixelfed want to be an alternative of Instagram. It will be federated with ActivityPub like Mastodon, Pleroma or many other plateform. Untill now you didn’t have any similar app as Instagram.


The only tools that could be similare was quit.im based on Gnusocial

It was a good start but Gnusocial seems to be slow developped and they didn’t have implemented ActivityPub yet.


Pixelfed was on early developpement today (end of July 2018) but we can start using it with few instances already available.

What is interesting is that the creator Daniel wanted to polish the look and feel. Contrary to other libre project that code the core first and then try to make a good design at the end, here you have a polished application. Many option are not open yet. You still can publish pictures, you have filters, you can comment and follow and been followed.

The federation is not open yet. That means that you cannot follow people from other instance.

If you are curious and want to create an account, you can find instance at the federation


French goverment will use Matrix Riot to replace Whatsapp

According to a recent report, the French government is currently developing an end-to-end encrypted alternative to WhatsApp and Telegram that its officials could use without worrying about foreign spying.

A Matrix/Riot-Based Chat Application

Although the French government’s spokesperson said that the government’s app will be based on open source software found freely available on the internet, she declined to name it. However, Matrix developers have confirmed that the app in question will be based on the federated chat Matrix protocol (a more modern XMPP/Jabber competitor) and, more specifically, on the Riot client, which uses this protocol.

Riot also comes with built-in support for the double ratchet end-to-end encryption algorithm, also used by Signal. Riot uses a variant of the double ratchet algorithm called Olm for strong end-to-end encryption for private conversations between two individuals, and Megolm, a variant for end-to-end encrypted group chats.

Megolm has variable privacy options in its library that developers will have to tweak before deploying. The reason for this is that some developers may prefer additional user convenience over maximum security.

Taking Control Of Own Data

The recent Cambridge Analytica privacy scandal seems to have reminded the French government and others, too, that you don’t have much control over your data if it’s being stored and processed by someone else. The French government will be able to fully control the Riot-based application by using open source code with its own modifications, if needed, and then run it on its own servers.

The French government’s spokesperson said that eventually this app may be available to everyone. However, French citizens will need to consider the fact that the app could also make enable their own government to spy on them more easily.

If the app’s source code remains public and transparent, and end-to-end encryption is enabled by default, it may not be a significant concern. It may still be preferable for citizens to use some other secure application developed by a non-profit group, whether that group is French or foreign.


What is Matrix

Matrix is an open standard for interoperable, decentralised, real-time communication over IP. It can be used to power Instant Messaging, VoIP/WebRTC signalling, Internet of Things communication – or anywhere you need a standard HTTP API for publishing and subscribing to data whilst tracking the conversation history.

Hubzilla 3.6 Released!

Mario wrote a notice to inform us that Hubzilla 3.6 is out.

The most notable change in the Hubzilla 3.6 release is probably the refactoring of the various activity filter/order options. Basically we got rid of the network tabs and replaced the functionality with two new widgets in left aside – activity_order and activity_filter. The order widget takes care of the various order possibilities – by commented date  (default), by posted date, by date unthreaded. The selected order is saved in the config and thus persistent.
The new filter widget displays all enabled filter options (privacy groups, personal posts, starred posts, forums etc.) in one widget. A new filter by contactname feature has been added and the notifications for unseen forum posts are now displayed in the notification widget. The privacy group management has been moved to the the panel chanel menu (your profile photo in the panel) and the management tool has been refactored.
The tags/mentions have been refactored and you will notice that the appearence of autofilled @mentions in the post editor look better readable now @{somechannel@somehub.org} instead of @channelname+365 before the change.
The cart addon has received major updates and has now support for paypal payments with automated fulfillment options (add buyer as contact, add buyer to privacy group and for admins only – change service class). A new gallery addon has been introduced to provide visitors of your channel a possibility to comfortably browse through your photo albums.

Other notable changes:


  • Webpage menus are now editable by visitors with webpage write permissions
  • Improve new channel creation workflow
  • Implement reset button for the post editor
  • Provide a general purpose GDPR document
  • Implement messagefilter for pubstream and sourced messages
  • Add supported federation protocols to siteinfo
  • Implement admin delete of files, photos and posts

Hubzilla is a powerful platform for creating interconnected websites featuring a decentralized identity, communications, and permissions framework built using common webserver technology.

The RedMatrix (aka « red ») is an open source webapp providing a complete decentralised publishing, sharing, and communications system. It combines communications (private messaging, chat and social networking), and media management (photos, events, files, web pages, shareable apps) with enough features to make your head spin.


What makes the RedMatrix unique is what we call « magic authentication » – which is based on our groundbreaking work in decentralised identity services. This ties all RedMatrix sites and channels together into a single super-network where the boundaries between different websites are blurred or seemingly non-existent; where « who you are » has nothing to do with « what computer you’re connected to », and where website content can adapt itself according to who is viewing it.


Warning: After experiencing magic authentication and nomadic identity, you may find it disconcerting and a bit « primitive » to go back to the old internet. You shouldn’t need hundreds of different passwords to use the web … or be totally isolated from your friends and family because a server or router in another country is having « issues« .


For the average person, the biggest advantage of decentralised identity is that you decide who you want to share your stuff with, and if somebody isn’t on your list, they’re not going to see it. It’s all under your control (we’re big on privacy). Use the RedMatrix as a social network or a business website or for personal cloud storage or media publishing – or any number of other uses; limited only by your imagination.

Osada is abandoned

6 month after his launch. The project Osada is abandoned by his creator.

Osada will be spun off (separated from Zap) and officially abandoned. If you want to take over the project, go for it. The implementation of Zot6 there is now frozen because future Zot6 work (and Zot8 – more on that in a moment) will not be compatible with ActivityPub. At all. As far as I know Osada is the only viable ActivityPub server for events and groups, but Friendica and Hubzilla aren’t very far off.

For those of you who don’t remember, Osada was a new platform with a UI reminiscent of Hubzilla that was specifically developed to support both Zot6 and ActivityPub-based networks. Macgirvin seems to indicate, in hindsight, that this was a mistake.

Zotiverse in january 2019

Zotiverse is a new word. It is the univesere that use zot protocole. : Hubzilla – Osada – Zap. Zot is much more powerfull than ActivityPub. It allow higher degree of security and anonity. But the best of zot is the nomadic identity.

Hubzilla is the most established product. It should be considered more of an « application platform » or maybe a « publication platform » (kind of like what WordPress has become since it now has plugins that allow you to do almost anything – it’s more than a Content Management System). « Social Media » on Hubzilla was one of the first use-cases adopted by a large number of people – and so many think it is primarily a social media platform. It is not. It is a privacy and security aware application platform that can support a huge number of use cases through the plugin/addon architecture which is lean and efficient.

Osada is more intended for end users interested specifically in Social Media applications that want to be able to communicate with ActivityPub but also have SOME of the privacy and security capabilities offered by Hubzilla. ActivityPub has a larger user base but is fundamentally incompatible with certain privacy and security models. So, anything related to ActivityPub is going to be a compromise. Osada is a social media platform that brings as much of the privacy and security features of Hubzilla as is possible while still providing integration with ActivityPub

Zap is a social media platform for those who are privacy and security minded and are not willing to compromise privacy and security just because « everybody is doing it. » It has the full range of privacy, security, and censorship resistant features inherent in the Zot protocol as Hubzilla (without Federation addons).

If you are an « end-user » of social media and want to be able to seamlessly communicate with ActivityPub, you want to use Osada. If privacy, security, and censorship resistance is important to you and you’re willing to give up access to other protocols in order to maintain those things, you probably want Zap. If you are primarily interested in providing content and data to others on an extensible and robust manner with privacy, security, and with built in ability to provide redundancy in case of failure or as a censorship resistance feature, you want to consider Hubzilla.

In other words, Hubzilla, Osada and Zap are the same kind of application with different tasts.

Now we are in transiton period. Because Hubzilla use an old version of zot. Osada and Zap use a new version (zot6). Once the Zot6 implementation on Hubzilla is complete, all of these projects will be able to intercommunicate with users on each of the others with fine-grained access control.

Add ActivityPub to your wordpress blog

Matthias Pfefferle annouce the avaibility of the plugin ActivityPub for wordpress.

This plugin implements the ActivityPub for your Blog. Your readers will be able to follow your Blogposts on Mastodon and other Federated Plattforms that support ActivityPub.

You can follow new post from any other activitypub account and comment. The comments comes directly to your wordpress comments.

Hubzilla 3.8 out

Mario announce in a post the availibility of Hubzilla 3.8

As you can see from the changelog, Hubzilla has gone through a very busy development cycle. To simplify the settings and improve the general UX, we have re-organised the entire apps and settings infrastructure.
Some features from the « Additional Features » section have been transformed to stand-alone apps and will need to be installed by the channel owner. Other features have been moved to the per app settings pages which are now easily accessible from the navigation bar or the app store.
Some addons have already been ported to the new apps infrastructure. This work is ongoing and will be completed during the next development cycle.

Other notable changes:


    • Remove tech-levels
    • Markdown table support
    • New addon (channelreputation) which provides a reputation system for community channels
    • Implement a subscriptions submodule for the cart addon
    • New addon (hsse) that implements a WYSIWYG editor
    • Experimental queue worker improvements (off by default)
    • Many under the hood improvements and bugfixes


As always, a big THANK YOU! to the translators and everybody who is helping to improve Hubzilla.

Howto upgrade:
Due to some profound changes to the addons it is necessary to follow this update procedure:


  • util/safemode on this will disable all enabled addons
  • util/udall the actual update which executes git pull for core and addon repos
  • util/safemode off this enables the previously disabled addons again
  • Install the upgrade info addon (optional) – this will show some info about the upgrade to your community members

Osada decentralised social networking

After Gnusocial, after Diaspora, After Friendica, hubzilla, Mastodon and others an new social network is coming.


Osada is a decentralised social networking application more familiar to refugees from Facebook and other conversational style social networks than it might be to those migrating from microblogging social applications such as Twitter.

Osada is very easy to use and provides a range of features either natively or through standard ‘Apps’. These include photo albums and file storage managers, events with attendance support, and topical groups/forums, all of which respect your personal privacy groups (such as Friends, Family, Coworkers, you name it).

ActivityPub Support

Osada has native support for the ActivityPub protocol (W3C standard) as well as the more advanced but lesser known Zot6 protocol. It can inter-operate with other social networking applications and projects in either of these spaces; for instance Mastodon, Pleroma, Pixelfed, PeerTube, Funkwhale, Zap, Friendica, Hubzilla, and many more.


A novel Osada feature which is unique to Zotlabs projects is the built-in hyper-drive social engine. This technology is essentially the secret sauce behind Facebook’s meteoric growth over a decade ago and this is the first time we’ve managed to replicate the essential bits using a decentralised protocol.

Public servers

There are a small but growing number of public servers available if you would like to try Osada without providing your own personal or community server environment. A list of these is available here. Only sites on this list with « Osada » in the « Software » name are compatible with projects using the W3C ActivityPub protocol. As the project is still in its infancy, we welcome additional public servers. There is a lot of interest in the project and we could use some help spreading the load.

Free and Open Source

The architecture supports themes and addons and a number of these are available today. Osada is open source under the permissive MIT license and runs on most modern LAMP servers, using MySQL/PostGres and Apache/Nginx. We are passionate about providing ethical and decentralised services running on open source platforms.

PeerTube 1.0 : a free and federated video plateforme

Peertube is a federation of sites that host videos. PeerTube uses WebTorrent technology. Each server hosts a torrent and each web browser viewing a video reshares it. This allows to share the load between the server itself and the clients as well as the bandwidth used through P2P technology.

The system works via a federation of instances run by independent entities. Each PeerTube server can host any number of videos by itself, and can additionally federate with other servers to let users watch. This federation permits to collectively host a large number of videos in a unified platform, without having to build an infrastructure comparable to that of the web giants. Each server is operated by and stays under the sole administration of a distinct entity.

PeerTube uses the ActivityPub protocol, in order to allow decentralization and compatibility with other services such as Hubzilla, Mastodon

15th of October 2018 the first version 1.0.0 has been relases.

Osada social network compatible with ActivityPub and Zot6

Osada is a social network compatible with ActivityPub (Mastodon, Pleroma, Peertube, pixelfed, Hubzilla etc… ) and zot6. It is based on the Hubzilla framework. That means if you are familiar with Hubzilla you will not be lost. The founder of Hubzilla never called Hubzilla a social network but a powerful platform for creating interconnected websites featuring a decentralized identity, communications, and permissions framework built using common webserver technology.

Osada is quite new in october 2018 and you will not find many information on search engine now. So if you need to know more I can give you a link on conversation about osada.

Now let’s talk technicks


Osada is a gateway server between nomadic and non-nomadic networks (such as between Zot|Zot6 and ActivityPub|Diaspora|Ostatus). A reference implementation is available at https://framagit.org/macgirvin

The purpose of Osada (« gypsy settlement ») is to resolve the dilemma that software which was not designed around nomadic identity won’t actually work correctly with software that is nomadic. The only other alternative is for all web communications software and protocols to be nomadic-aware and this is unlikely to happen.

In prior efforts such as RedMatrix and Hubzilla, federation with non-nomadic networks was offered as a choice. You could choose federation or nomadic identity. Choosing both leads to a situation where expected communications are not delivered and both federation and nomadic operation are flawed in basic ways. Osada resolves this basic dilemma by providing a gateway service between the two incompatible paradigms.

At a high level, Osada provides a non-nomadic server which can federate with all existing networks (to the extent that those networks permit federation; ActivityPub and Diaspora have limitations on their ability to federate third-party messages between incompatible protocols).

On the nomadic side, Osada does not allow nomadic operation itself, but it supports nomadic communication. It uses a Zot6 concept called « linked identities » to transfer information into and out of the nomadic network. The linked identity on the Osada side is not a clone and has a distinct non-nomadic identity. It can be bound to a nomadic identy on the Zot6 network. All federation and cross-protocol communication occurs at the bridge. If the linked identity relationship is severed for any reason (including failure/shutdown of the bridge), all bridged communications will cease.

Osada identities can be moved/relocated and connections on non-nomadic networks which support account moves will be retained. Connections on services which do not allow moves will be lost.

People inside the nomadic network will make connections to the nomadic identity. People on outside networks will make connections to the Osada identity and will be (likely) unable to resolve the internal nomadic identity as something they are able to federate with

If you want to try osada : https://osada.usezot.net/ the-federation.org have not added that project yet. I hope it will be added soon



An introduction to the protocol that powers Hubzilla

The world is full of protocols. Some are loosely defined by society, and some are rigidly defined by their architects. In many urban environments, for example, there is a protocol for how you ride an escalator: if you choose to stand, you stand on the right side so that those who choose to step can get past on the left. If you ignore this protocol, you may get some annoyed looks but you will still get where you are going. More rigid protocols, such as the hypertext transfer protocol (HTTP) that governs most communication on the web, can be much stricter and more elaborate. If your browser puts one semicolon in the wrong place you can forget about seeing those cute cat videos.

So what does that have to do with Hubzilla? And for that matter, what is Hubzilla anyway? Hubzilla is free and open source software designed to support your freedom and privacy; anyone can run it on their own server and inspect the code to learn how it works. It is an advanced platform for online communications and content publishing that provides decentralized access control. That last bit is the critical difference between Hubzilla and all the other blogging platforms, social networking sites, and messaging systems that dominate the web today, and it is precisely the motivation for inventing Zot instead of choosing from the plethora of existing communication protocols. To appreciate what is so innovative about Zot, we need to explain first what « access control » means and then why « decentralized » makes the problem of access control challenging.

Like protocols, the world has no shortage of access control. Does your house have locks on the doors? Do you let everyone watch you take a shower, or do you prefer to control access to that activity? How about conversations about your finances? I bet you publish those on billboards, right? Of course not! We all constantly control access to things for many reasons.

And sometimes you want to have a private conversation with someone that no one else should read.

Electronic publications and communications are no different. You may want to publish an article like this one for the whole world to read, but you may also want to participate in a restricted access forum online where members of your neighborhood can discuss community issues. And sometimes you want to have a private conversation with someone that no one else should read.

The traditional centralized solutions to these problems have existed for many years and are what virtually everyone currently uses online. This is because it is relatively easy to manage access control when you have one central authority acting as the gatekeeper to content. Facebook is the most influential example of this model. If you send a message to a select group of friends, only they have access to it because Facebook (1) authenticates them by identifying who they are based on their knowledge of their secret account password and (2) authorizes them to access the message by verifying that they are on the message’s access control list (ACL), which is the technical term for what you created when you « sent » them the message.

There are several fundamental and serious problems with this centralized model. Arguably the biggest problem is that you do not own your identity. But that’s absurd, you might immediately retort, of course I own my identity! Well, let’s consider what ownership means. Ownership of identity means, for one thing, control. If you own your identity, you control it somehow. With Facebook and similar centralized services, they alone have the power to create and delete your online identity. They grant you access to your identity when you log in. As the years roll by and you share all sorts of content with all the people you have connected with, you may be alarmed to discovered that you need the centralized service. If you want to leave, all of that shared content and all those connections vaporize. What’s worse, you can’t even share something privately with people unless they also allow their identities to become hostage to the platform. It’s like some kind of pyramid scheme.

They grant you access to your identity when you log in.

Now we can begin to appreciate some of the benefits of decentralization in our online communications. When you register an account on a “hub” — a server running Hubzilla — you can make connections with other people and share things even when they are on completely independent hubs operated by different companies or organizations. This is the essence of what it means when we say Hubzilla is a decentralized network. We like to call the network of Hubzilla-powered websites “the grid”. There is no single entity that controls the network or, by extension, you. It is ironic that this needs explanation, because the most ubiquitous and long-lasting online communication system — email — is a shining example of decentralization. Anyone can run an email server and exchange emails with other people, even if they are using an email server hosted by a separate business or university. As robust as email has been historically, however, it lacks a lot of capabilities that we want in modern communication. It is designed for passing small messages back and forth; it is not designed for controlling access to published content hosted on a modern website using secure encryption methods. This is what Hubzilla is designed to do. Hubzilla lets you do things like share photos privately with only your family and friends, or publish news articles only to paying subscribers, even if none of these people have an account on the server hosting the content.

What makes Hubzilla truly unique is combining the ideas of decentralized access control and identity ownership. The result is something that is frankly revolutionary: it’s called nomadic identity.

To be clear, providing decentralized access control is an impressive feat per se. There are only a few other platforms available that provide this capability on the « standard » internet of websites accessible by browsers over HTTP. What makes Hubzilla truly unique is combining the ideas of decentralized access control and identity ownership. The result is something that is frankly revolutionary: it’s called nomadic identity. Truly owning your online identity means that you maintain your contacts and access to the things people have shared with you even if you change accounts on different servers. It means that you can have clones of your identity on independent hubs allowing you to maintain your online presence and continue communicating even when one of your servers is unavailable (temporarily or permanently). No other platform provides this level of robust identity ownership.

Nomad mobile application for hubzilla

Nomad is an application for Hubzilla. It  You can install it from the Fdroid application.


It’s currently under development and should be used with that in mind. Please submit any bugs you might find. We are basing our work on the dandelion* app. The is a webview based app developed as a WebApp

Why is a WebApp better than using the mobile site on a browser? Basically it provides better integration with the system (events coming into and going out of the app), customized interface and functions and a nice little icon that takes you directly to your favorite social network 🙂
