GPG transition statement

This transition statement can be also downloaded from here

Hash: SHA256,SHA1

I am transitioning my gpg key from an old 1024-bit DSA key to a new
4096-bit RSA key. The old key will continue to be valid for some time,
since I have no reason to believe that my old key may have been
compromised, but I prefer all new correspondance to be encrypted in the
new one.

This transition document is signed with both keys to validate the

If you signed my old key, I would appreciate signatures on my new key as
well, provided that your signing policy permits that without
reauthenticating me.

The OLD key was:

pub 1024D/7BEBC6C7 2009-07-01 [expires: 2017-01-14]
Key fingerprint = FCF7 7D8C C5CA 2CEE BA04 C653 697B 4A6F 7BEB C6C7

And the NEW key is:

pub 4096R/C724C83C 2015-10-23 [expires: 2025-10-20]
Key fingerprint = F68E 8B9A 4F66 5A1B 5E35 DFA1 13C7 0A5E C724 C83C

To fetch my new key from a public key server, you can simply do:

gpg –keyserver –recv-key 0x13C70A5EC724C83C

If you already know my old key, you can now verify that the new key is
signed by the old one:

gpg –check-sigs 0x13C70A5EC724C83C

If you don’t already know my old key, or you just want to double check,
you can verify the fingerprint against the one above:

gpg –fingerprint 0x13C70A5EC724C83C

If you have both my keys, you can also verify that this document is
signed by both:

gpg –verify drdanz-transition-statement-20151024-signed.txt

If you are satisfied that you’ve got the right key, the UIDs match what you
expect, and if it’s compatible with your key signing policy, I’d appreciate it
if you would sign my key:

gpg –sign-key 0x13C70A5EC724C83C

Lastly, if you could upload these signatures, i would appreciate it.
You can either upload the signatures to a public keyserver directly:

gpg –keyserver –send-key 0x13C70A5EC724C83C

Or you can send me an e-mail with the new signatures (if you have
a functional MTA on your system):

gpg –armor –export 0x13C70A5EC724C83C | mail -s ‘OpenPGP Signatures’

Please let me know if there is any trouble, and sorry for the

KDE Telepathy wants you!

A couple of days ago, on KDE Telepathy mailing list was brought to our attention this graph (Source):

KDE Telepathy Bug Reports Count (Open bugs only)
KDE Telepathy Bug Reports Count (Open bugs only)

The graph shows clearly that the number of bugs reports affecting KDE Telepathy is increasing.
Quite unlikely this is related to the quality of the software, but to the numbers of KDE-Telepathy users.

Editing the query a little bit I came to this graph, definitely more interesting (Source):

KDE Telepathy Bug Reports Count (All bugs)
KDE Telepathy Bug Reports Count (All bugs)

The trend is in my opinion really impressive, and shows clearly the amazing job that has been done on KDE Telepathy since February 2011.

Bugs have been closed at a very constant rate, new features added, new versions released (0.5.1 was released about 20 days ago), and translators are doing a great job, with the result that now KDE Telepathy is packaged for most of the major GNU/Linux Distributions and at least 2 of them use it as default instant messaging framework for the KDE Desktop.

This implies new users, but obviously comes with a lot of new bug reports and new features requests.

That’s why we need you! Of course we need new developers to help us fixing bugs, we have junior-jobs if you are starting programming and want to learn, and we are very happy to help you! 😉
But if you are not a coder, and you want to help us join us on #kde-telepathy on freenode, we have a lot of tasks for you anyway!

  • Report new bugs, try to reproduce and confirm the existing ones, find out the duplicates, locate related bug on upstream and downstream bugtrackers
  • Update the wiki, write the documentation for the applications
  • Test Adium chat themes, help us fixing the broken ones
  • Translate the languages not yet translated
  • Reply to users questions on the forum and mailing lists

Concluding: We are awesome, want to be awesome too? Join us

Some Fun with ktp-text-ui Plugins

KDE Telepathy 0.5 was released last month, introducing a brand new filtering plugin system for the text-ui. I didn’t have much time to work on KTp recently, due to my new job and to my new wife (no I don’t have an old one) but since in Randa people are slacking (evil grin), someone has to do some real work (laughing hard), so I’ve being playing a little with the text-ui and with the plugins.

Formatting Plugin

First of all, I fixed the formatting plugin. This allow you to format plain text, like Thunderbird Structured Text:

  • *this is bold*
  • _this is underlined_ (and not italics!)
  • /this is italics/
  • -this is strikethrough-

The plugin was disabled in 0.5 because it was broken (the regular expression detecting the tags to replace was not detecting correctly).
Beside fixing it, I modified it to avoid changing the text by removing the tags (i.e. ‘*’ or ‘/’). In this way, even though it might format some parts that user is probably not expecting to see formatted (for example some /*C comments*/), copy and paste will still work.
Moreover, I made it so that it will be very easy to add a configuration dialog to change its behaviour, so if you _really want this to be italics_, you will probably be able to configure it according to your needs in the future.

This plugin will be enabled by default in 0.6.

Syntax Highlighting Plugin

We often think about the final users, but sometimes we have to think about the developers 😉
So I wrote a syntax highlighting plugin using jquery-snippet

A few screenshots are better than thousand words, so…

Meanwhile David had another cool idea for the syntax highlighting plugin: include a kate part into the qtwebkit view (You can find some details about how he did that here). This is his result:

Both approaches work great, my approach is more integrated in the chat, but David’s approach is also quite interesting. We don’t know yet whether release just one of them or both… Opinions?

Anyway, in order not to try to highlight all the messages, at the moment code must be included in a block like [code lang='cpp']...[/code]. This can be a bit annoying. Moreover copying and pasting code in the chat-ui is boring. Something like pastebinit would be really useful. That’s why I started writing…


This a very simple tool but it is something I’m really proud of, and that shows the potential of Telepathy…
It is a simple command line tool that reads from stdin and sends everything as a single message to a telepathy contact.
it takes as parameters, the account to use, the contact to send it to, and an optional parameter --format <language>.
If this parameter is specified, then the message is automatically included in a [code lang='cpp']...[/code] block using the syntax specified.

A few ideas for using it…

  • git show | ktp-paste-contact --format diff --account <account> --contact <contact>
  • cat file.cpp | ktp-paste-contact --format cpp --account <account> --contact <contact>
  • echo "Hey dude, I'm so geek that I'm texting you from the command line" | ktp-paste-contact --account <account> --contact <contact>

You can find the code for the code-highlighting plugin in my clone repository for ktp-text-ui (kde:clones/ktp-text-ui/ddomenichelli/ktp-text-ui branch plugin-code) and for ktp-paste-contact on my brand new scratch repository (kde:scratch/ddomenichelli/ktp-paste-contact.git)

Enjoy it!

EDIT: I found a great way to convince your friend to block you! Perhaps it can be used against spammers 😛

while true; do echo "MUAHAHAHAHAHA" | ktp-paste-contact --account <account> --contact <contact>; sleep 5; done

KDE Telepathy at Akademy 2012

I'm going to Akademy 2012
I'm going to Akademy 2012

As you can imagine from the picture above, I’m going to Akademy 2012 in Tallinn, Estonia! Thanks a lot to KDE e.V. for sponsoring me.

This year at the conference there will be a lot of interesting talks but unfortunately none of them about KDE-Telepathy.

Instead we will host 2 BoF sessions:

Moreover most of us will probably attend at the Web Accounts BoF:

I can’t wait to see you all in Tallinn!

KDE Telepathy in GSoC 2012

We had several good proposals related to KDE Telepathy for Google Summer of Code 2012, but unfortunately we only got 2 slots! But hey, we got 2 slots! That’s great! 😀 Thanks to Google for organising and sponsoring it.

The first accepted project is “Message Filtering Plugin System” by Lasath Fernando (shocklateboy92), the author of the chat plasmoid that will be released in KDE Telepathy 0.4. He will be mentored by David Edmundson and

“will create a completely asynchronous modular and extensible system that enriches messages before they’re displayed to the user. These includes embedding images and videos from links, Translating messages, (re)-formatting them nicely, reading out loud etc.”

The second project is “Enhancement to peer-to-peer DBus for Telepathy DBus Tubes” by Puneet Goyal. Puneet worked on the Payment Detection use-case of project Alkimia in Season of KDE 2011. I will be his mentor for this interesting project which aim is to make it even easier to use D-Bus Tubes from any KDE application:

“When an application connects to a peer to peer dbus tube, it must know what exactly to look for. Even When it registers for another object, the other side of the tube must know about it. So the ideas is to create a class that could ease the object to register and unregister on the DBus Tubes, and to provide you with an interface similar to the one as a DBus Server.”

We had to reject several good projects, because of the limited amount of slots, but if you are motivated to work on a project in KDE Telepathy you still have one chance[1]: Season of KDE (SoK)! SoK is similar to Google Summer of Code: you won’t be paid, but you will get a mentor, a very cool t-shirt and certificate! If you want to apply, you can have a look at KDE Telepathy ideas that we selected for GSoC but did not get a slot (“Telepathy setup for KDE multiplayer games” and “Collaborative editor“), check out some more ideas here or propose your own idea.

[1]Actually you have as many chance as you want to contribute even if you don’t want to take part to SoK! We have several junior jobs if you are (or want to become) a developer, and a few non-programming tasks that don’t require programming skill if you just want to help us!

Digikam Code Sprint @ Genova + Telepathy KIPI Plugin

This post was supposed to be published yesterday January 18th 2012, but I’m delaying it of 24 hours in support of SOPA STRIKE

Last weekend the Digikam Code Sprint was held in Genoa (Italy). Yes, I’m not a Digikam developer, but I live in Genoa and this was a very good occasion to implement something that I’ve being planning to implement for a long time: A KIPI Plugin for Telepathy. So before saying anything else, here is the mandatory screenshot:

Telepathy KIPI Plugin
Telepathy KIPI Plugin

Thanks to this plugin, you will be able to send your pictures and albums from digikam, showfoto and any other application using KIPI plugins. Most of all I wanted this feature in KSnapshot, and yes this is now possible.

This is something I already implemented in the past [1] but I must admit that having all the contacts in a menu was a bad idea, so I gave up at the time… So this time we have a widget instead that takes shows only the person that are online, that can accept a file transfer and there is a bar to filter by name (actually most of this is widget is “borrowed” from Telepathy Send File, written by David, so credits for that go to him). I think this solution is much better than the menu, but comments are very welcome.

Unfortunately the widget won’t be in KDE Telepathy 0.3 so you will have to wait for the 0.4 release, and then you will have to wait for the kipi-plugin to be reviewed by the digikam developers… Meanwhile it will reside in my clone repositories (I will update this post with the links as soon as the code is available)

P.S. Thanks to ALID (especially to Angelo, Stefano and Claudio) and KDE e.V. for hosting, organizing and supporting the event and to all the Digikam developers.

MSN+XMPP in KDE Telepathy

As Xavier already wrote on his blog,

Microsoft announced that they had added XMPP to their Windows Live APIs. Microsoft announced that they had added XMPP to their Windows Live APIs. That means that any Jabber client could connect to MSN using our favorite open IM protocol! No more closed protocol to reverse-engineer.

Since Gabble now supports it, I just had to add a little bit of magic to support the Messenger OAuth2 authentication in KDE-Telepathy Auth Handler and add a profile to the Account Manager. Microsoft implementation still have some problems (you cannot add/authorize new contact, yahoo contacts are not shown, etc.), therefore by default the “old” method will be used, but we think that it is important that people starts using it, therefore starting from KDE Telepathy 0.3 (that will be released the 25th of January) you will be able to use XMPP protocol with your MSN account.

It is important to notice that you can have just one MSN-XMPP account at the moment, so here is how to add it.

First of all, you have to add a new account from System Settings > Instant Messaging and VOIP > Accounts > Add Account > Others > choose the “MSN (using XMPP)” profile and click Next

MSN (using XMPP) profile
MSN (using XMPP) profile

OAuth2 authentication is a little bit different from the normal authentication. You don’t have to set any parameter, just click “Finish” in the next tab.

Just click "Finish"...
Just click "Finish"...

Now the magic will happen and the Authorization Handler will popup with a dialog where you have to insert your Windows Live ID and your password, then click “Sign in”

Insert your Windows Live ID and your password, then click "Sign in"
Insert your Windows Live ID and your password, then click "Sign in"

Finally you will get another page where you have to authorize the application to connect, by clicking on “Yes”

Click "Yes"!!!
Click "Yes"!!!

And you should be connected.

Have a nice chat! 😀

P.S. Due to this bug, if you manage to connect the first time, but you fail later, try deleting the account and repeating those steps… [EDIT: Fixed before 0.3]

P.P.S. Thanks to Xavier for the support and the suggestions!

EDIT: MSN OAuth2 authentication requires telepathy-gabble >= 0.15.0

KDE-Telepathy + Service Monitor

Today I found this plasma applet named “Service Monitor“, I thought it could be useful to monitor telepathy services, so I played a little with it and I wrote a couple of XML files containing definitions for Telepathy and KDE-Telepathy services, and here is the result:

KDE-Telepathy Service Monitor
KDE-Telepathy Service Monitor

I find it quite useful, it allows you to choose the services you are interested in among the ones installed, monitor which services are running, start and stop them from the applet.
Moreover thanks to that I already found a bug in the auth-handler that doesn’t exit when it is supposed to do so, so I’m sharing the xml files hoping that they can be useful for someone else. If you are interested you can find them here: git://, you just import the xml files from the “Manage Sources” tab in the config dialog for the applet.

P.S. All credits for Service Monitor go to the original author.

KDE-Telepathy Sprint (aka Woshibon) 2 – Day 3

Today was sadly the last day of the sprint. We had some more discussion, a short course by grundleborg about unit tests, a short walk around Cambridge after launch and a lot of hacking. Moreover we decided the new features that hopefully will land in the next release. We have a list of 22 cool features that we we want to implement before the 8th of October (soft freeze for Tech Release 0.2). And this list doesn’t include the stuff implemented and all the bugs fixed after the 0.1 release. Unfortunately audio and video call won’t land in the next release due to dependency problems (but if you are brave enough you will be probably able to compile the dependencies and the audio call ui from the git repository), and Nepomuk integration and contact merging will be delayed some more. However we will have drag and drop of contacts from the contact list to the desktop, integration with kwallet (a little hackish for the moment but that’s all we can do until the secret service will be integrated in kde), a new auth-handler for handling passwords and ssl certificates, auto away and now playing system, desktop sharing with contacts, and much more. Finally we will have some small changes in the git repositories and we plan to release the 0.2 release both as a set tarballs (one per module) and as a single tarball to help packagers in their work. We really believe that the next release will be awesome!

A few conclusive random thoughts about the sprint:

  • We were the same number of people last year at the sprint. However in the last year the team gained several new important members!
  • Opening new bugs is something that grundleborg can do damn fast.
  • Sprints are really funny, and at the same time you get a lot of work done.
  • Help is always needed! If you want to contribute, please join us on #kde-telepathy
  • I won’t to wear the same shirt for the next sprint. (See here).
  • Brasil and Australia are really far.
  • Of course thanks again to Collabora and KDE e.V. for sponsoring the event.
  • Nepomuk shall not die! Please support trueg and the Nepomuk project!

P.S.: Visa is something that should be abolished.
P.P.S.: You don’t want to mess with Thor.

KDE-Telepathy Sprint (aka Woshibon) 2 – Day 2

Very busy day, lots of things to do, bugs to fix, new feature to implement…
But first of all thanks to Collabora and KDE e.V. for hosting and sponsoring the event and the pizza yesterday!

The morning started with several important stuff, discussions, etc. but around launch time the situation was this:

Almost all tasks and discussion completed!
Almost all tasks and discussion completed!

Of course nobody will ever be able to satisfy the last! (I’m kidding, thanks alin for testing and reporting bugs :D)

In the afternoon we started implementing some of the features that we are planning for 0.2 release and we got some impressive results!

  • nwoki fixed the audio call
  • d_ed (also known as “the release manager”) implemented drag and drop of contacts to plasma desktop
  • mck182 implemented the auto away system
  • woshibon is now the official name for KDE-Telepathy sprints
Woshibon group photo

We had dinner at an indian restaurant and mck182 definitely ate something too spicy for him

Vindaloo is too spicy for mck182
Vindaloo is too spicy for mck182

At the moment the hacking is still going on in the lobby of our hotel, 5 people are connected to the internet using d_ed’s android phone as an access point… that’s cool!

Tomorrow is the last day of the sprint and the list of the new features in the 0.2 technical release should be available before the end of the day, hopefully together with some new features and perhaps a screencast?
