We started as Today with a Techie 8 years, 5 months, 4 days ago. Our shows are produced by listeners like you and can be on any topic that "are of interest to hackers". If you listen to HPR then please consider contributing one show a year. If you record your show now it could be released in 14 days.
Now it is time to take a look at practical uses of encryption, and the number one use is for e-mail. Encrypted communication via e-mail is very desirable if you want to keep a secret. In the U.S. the current legal precedents say that any e-mail left on a server is not protected since you would have no expectation of privacy. This precedent was set many years ago when POP3 was the standard for all e-mail and people did not usually leave e-mail on a server. These days, many people use web-based e-mail or use a newer standard called IMAP which by default stores everything on the server. Perhaps you are one of these people, and thought that you had a right to expect privacy, but in the U.S. you dont, and I would expect that in many other countries the situation is no better.
There have been attempts to provide encrypted e-mail service from a service provider, but the problem here is that the provider usually has to have to the key in order to encrypt the e-mail, and if they have the key they can be compelled to give it up. Recently in the U.S. there was a case involving Ladar Levison who ran such a service called Lavabit. Lavabit encrypted mail in transit using TLS encryption, and he had the keys. When his service was used by Edward Snowden, the government came to get the keys. Now, Levison would have given them the key for Snowdens e-mail if he had been served a warrant, as he always made clear to his customers that he would obey proper legal demands. But in this case the government demanded that he turn over all of the keys for all his customers, and this was too far for Levison. He shut down his service rather than cooperate, and is a bit of a hero for that. But it illustrates that you are at the mercy of the service provider. If the government made this demand to Lavabit, you are safe in presuming they had made the same demand to other providers, and that they all cooperated with the government and said nothing to their customers. So it would be mistake to rely on 3rd party mail service providers to give you privacy. You need to control it yourself. But of course, after the last few lessons you know how to do that, and have your secure keys created. You just need to put them to use.

In this episode, deepgeek suggests that adding and old, and perhaps laughable by modern standards, device to your mobile lifestyle. Deepgeek reveals that said device is the pager, but he eventually gives good reasons for doing so.
The primary reason is that the paging company does not know where you are, so they can't tell "the man" where you are. Other reasons are reduncancy and trouble interpreting audio. But in the end, you find out why first responders and medical and fire personal still use these devices, and how you, as a privacy lover, may reap benefits from using this technology also.

This interview with Julia Velkova and Konstantin Dimitriev will shed some light on free culture, open animation, Synfig Studio and the Russion animé being developed by the Morevna Project. Today, on Hacker Public Radio.
"Support Open Animation projects! Because they cary a lot of potential for inovation."
-- Julia
We all know of the Blender Projects, like Elephants Dream, Big Buck Bunny and Sintel, but do you know of any more? Creating an animated movie is hard. Many enthusiasts start projects up that soon thereafter unfortunatly die off.
The state of this area of interest is what Julia Velkova has concentrated her resarch on. At FSCONS 2012 she gave the first part of a presentation, painting a picture of the state of matters, then followed by open animator Konstantin Dimitriev who introduced both the Morevna Project and the free and open source tool Synfig Studio.
At this presentation Konstantin showed the premiere trailer for his animé movie "The Beautiful Queen Marya Morevna", a modernized version of a traditional Russian tail. Both the trailer and Julia and Konstantins presentations are availible on YouTube.
Konstantin has used indiegogo to crowdfund a full time developer for Synfig Studio. He wrote: "I am mentoring a full-time developer Ivan Mahonin, who is working on Synfig code. We have funded his work in previous months by running similar fundraising campaigns for October, November, December, January and February." So go help them with the rest of 2014 as well!
Go help the Morevna Project and Synfig Studio, follow both Julia and Konstantin on Twitter to get updates on this very interesting part of the free and open community that I suspect we sometimes might forget.

As we mentioned in beginning our look at Page Layout, you have some options other than just Page Styles and Frame Styles, useful though they are. So let’s spend a few moments looking at these other options and see how they work.
Tables can be a useful tool for more than just displaying tabular data. You can place different object in each cell of a table and so have some control over how things are laid out on the page. You could, for instance, place your sub-heads in a left-hand column, and the associated text in an adjoining column, which gives you the same effect as using the Marginalia style. And you can add pictures, charts, and other objects as well. You can even insert a table into a cell of another table to get more fine-grained control. In fact, in the days before Cascading Style Sheets and Javascript, tables were the primary way of laying out Web pages, though these days that is frowned upon, and in any case most Web pages are now created using some kind of CMS software like WordPress, or Drupal. The idea of using tables was more attractive when we realized you could turn-off the cell borders and make them invisible. Of course, in Writer documents that only works when they are printed. When opened on a computer the table borders are still visible, as indeed they would have to be for you to edit the document.

Jörg Steffens explains that bareos is not "bare os" but rather Bareos - Backup Archiving REcovery Open Sourced.
Bareos is a 100% open source fork of the backup project from bacula.org. The fork is in development since late 2010, it has a lot of new features. The source has been published on github, licensed AGPLv3.
Lights, Sensors, Switches, Dimmers and of course the obligatory RaspberryPi and a bread board. So what is this you ask ? Well Ralph Meijer, Edwin Mons and Joachim Lindborg explain the "Internet of things" and how they want to use the XMPP protocol to "chat" with your devices. The plan is simple: set-up each device so it can talk to XMPP, then you can use Jabber or any other XMPP client to talk to them.
The lads from the XMPP realtime lounge
The Extensible Messaging and Presence Protocol (XMPP) is an open technology for real-time communication, which powers a wide range of applications including instant messaging, presence, multi-party chat, voice and video calls, collaboration, lightweight middleware, content syndication, and generalized routing of XML data. The technology pages provide more information about the various XMPP “building blocks”. Several books about Jabber/XMPP technologies are available, as well.
We have a chat with Emil Ivov, the project lead of Jitsi.
Jitsi (formerly SIP Communicator) is an audio/video and chat communicator that supports protocols such as SIP, XMPP/Jabber, AIM/ICQ, Windows Live, Yahoo! and many other useful features. Jitsi is Open Source / Free Software, and is available under the terms of the LGPL.
To wrap up the show I managed to track down Jan-Frederik Martens from the FOSDEM team.

Next a chat with an Evildragon aka Michael Mrozek who talks to us about the OpenPandora device, and what's coming next.
The Pandora is a handheld game console designed to take advantage of existing open source software and to be a target for homebrew development. The first copy was released in May 2008 and others in May 2010, and is developed by OpenPandora, which is made up of former distributors and community members of the GP32 and GP2X handhelds. When announcing the system, the designers of Pandora stated that it would be more powerful than any handheld video game console that had yet existed. It includes several features that no handheld game consoles have previously had, making it a cross between a handheld game console and a subnotebook.
We stop by the Python booth and find out how to tame the beast.
Python is a programming language that lets you work more quickly and integrate your systems more effectively. You can learn to use Python and see almost immediate gains in productivity and lower maintenance costs.
We talk to Kohsuke Kawaguchi the lead developer of Jenkins.

The Jenkins mascot
From Wikipedia:
Jenkins is an open source continuous integration tool written in Java. The project was forked from Hudson after a dispute with Oracle. Jenkins provides continuous integration services for software development. It is a server-based system running in a servlet container such as Apache Tomcat. It supports SCM tools including AccuRev, CVS, Subversion, Git, Mercurial, Perforce, Clearcase and RTC, and can execute Apache Ant and Apache Maven based projects as well as arbitrary shell scripts and Windows batch commands. The primary developer of Jenkins is Kohsuke Kawaguchi. Released under the MIT License, Jenkins is free software.
Over at the Puppet booth we talk to Eric Sorenson from PuppetLabs and Bert Van Vreckem from the Belgium Puppet user group.
Puppet Open Source is a flexible, customizable framework available under the Apache 2.0 license designed to help system administrators automate the many repetitive tasks they regularly perform. As a declarative, model-based approach to IT automation, it lets you define the desired state - or the “what” - of your infrastructure using the Puppet configuration language. Once these configurations are deployed, Puppet automatically installs the necessary packages and starts the related services, and then regularly enforces the desired state. In automating the mundane, Puppet frees you to work on more challenging projects with higher business impact. Puppet Open Source is the underlying technology for Puppet Enterprise and runs on all major Linux distributions, major Unix platforms like Solaris, HP-UX, and AIX, and Microsoft Windows.
