XMPP Mobile groupchat — Introducing MUC Subscription (MUC Sub)
Sounds like a good idea: XMPP groupchat (MUC) without needing presence, i.e. staying in without being online all the time. IMHO, not only interesting for mobile, but all users. https://blog.process-one.net/xmpp-mobile-groupchat-introducing-muc-subscription/ #xmpp #muc #ejabberd
[Bitcoin Munich] Next Meetup: Thursday, Dec 22nd - Paper Wallets Workshop
Did you know you can print your bitcoins on paper and store them safely offline that way? Also holiday season is near, so we'll have an introduction talk and workshop about paper wallets, which make an original and unusual Christmas gift as well.
Apart from that, far beyond the use in Bitcoin and crypto-currencies, the concept of private and public keys, as depicted on such a paper wallet, may become more and more pervasive in the future in general. Passwords seem to be unsafe, as users forget them or pick too easy ones. And no matter what certain big hardware and OS manufacturers try to tell you, biometric identification like face or fingerprint recognition is unsafe as well and can easily be spoofed, as often demonstrated by ethical hackers.
So we'll take a look how secure (while hopefully still easy) identification and authentication may look in the future of a blockchain world. Maybe personal crypto-key management can and will some day become an intuitive habit in everyday life, just like we're used to handle our physical keys.
Target audience: Beginners
You're encouraged to bring your tablets or notebooks for this hands-on session! You should already own some bitcoins (or fractions), and have a wallet installed, e.g. Electrum.
19:00 Doors open, get-together, food + drinks

Mediated Information eXchange (MIX) is the proposed successor of the well-known Multi-User Chat (MUC). Ralph Meijer, chair of XSF and director of XMPP Council, writes about the not-so-far future of this XMPP extension:
MIX takes the good parts of the Multi User Chat (MUC) protocol, that has been the basis of group chat in XMPP for quite a while, redesigned on top of XMPP Publish-Subscribe. Modern commercial messaging systems, for business use (e.g. Slack and HipChat), as well as for general use (e.g. WhatsApp, WeChat, Google's offerings), have tried various approaches on the ancient model of multi-part text exchange, adding multi-media and other information sources, e.g. using integrations, bots, and cards.
MIX is the community's attempt to provide a building block that goes beyond the tradional approach of a single stream of information (presence and messages) to a collection of orthogonal information streams in the same context. ... All-in-all MIX allows for much richer, multi-modal, and more scalable interactions. ... I expect the discussions at the XMPP Summit to tie the loose ends as a prelude to initial implementations.
I am sure that FOSDEM and the XMPP Summit will have many more exciting topics, so I hope to see you there. Until then, Jabber on!

Available Debian package updates via XMPP
Long time ago, I needed an XMPP bot informing the admin chat room about Debian package updates on different machines. I didn't found one, so I hacked a small script, called Pain in the APT.
What does it do?
- updates the APT cache and checks for updates
- sends list of available updates to Jabber contacts or a conference room immediately
- sends list of available updates and relevant changelogs (slow) to email recipients
- downloads packages, but does not install them

Jamie McClelland writes, that it is still difficult to have a secure group chat. But it's possible.
Use either Conversations for Android (f-droid or Play) or Gajim for Windows or Linux [...]
Ensure that everyone in your group has added everyone else in the group to their roster [...]
Create the group in the android Conversations app, not in Gajim [...]

Use IRC from XMPP with Debian
Biboumi 6.1-1~bpo9+1 and Prosody 0.10.0-1~bpo9+1 are now available in Debian 9 (stable, stretch) via backports. Biboumi is a gateway from XMPP to IRC and can be used with Prosody or any other XMPP server. It allows XMPP users to join IRC channels as if they were MUCs. Very useful!
#biboumi #prosody #xmpp #debian #freesoftware #irc #muc
biboumi is an XMPP server component, that acts as a gateway to IRC. It is used e.g. by movim.eu and other public XMPP servers. But it is also very easy to install and configure on your own XMPP server, if you happen to run one.
According to the changelog, the new version supports PostgreSQL in addition to SQLite and fixes a number of bugs.
You may want to join the XMPP MUC xmpp:email@example.com?join, especially if you are a C++ hacker and like to help.
