Introduction

This article represents the latest instantiation of sven-radde.de. We argue that its creation provides three significant benefits: It is useful by providing a contact form, a short CV and a centralized list of Sven's academic publications, it serves as a demonstrator for current web technologies by using a mobile-first design that relies on HTML5 and advanced Javascript techniques, and, last but not least, it was great fun to build.

The rest of this article is organized as follows: We present our newest results in section 2, before providing multiple ways to contact the author in section 3. Section 4 gives a short version of the author's CV, while section 5 discusses related work along with the author's academic publications. Finally, we conclude with a short summary and outlook in section 6.

The contents of this section will be expanded as part of our ongoing work. Furthermore, they are available as an  RSS newsfeed for your convenience.

Contact

Electronic mail

In spite of the increasing prevalence of alternative communications channels, direct email messaging is still our preferred means of communication, due to its universality and flexibility. In case you do not know an email address that can be used to reach the author, the form detailed in Fig. 1 is provided for your convenience. Note that all fields are required.

You are accessing this website over a secure connection which will hopefully frustrate any would-be eavesdroppers. In particular, all information that you submit via the above form is sent encrypted to the author's mailbox which Sven will also access over encrypted connections only. For additional security, PGP end-to-end encryption keys are provided, as we will describe in the following subsection.

Encrypted email

In order to improve the security of our communications against eavesdroppers, we encourage our correspondents to encrypt all messages to the author using the PGP/GnuPG keys provided in Fig. 2 below. If the receivers have indicated an interested in secure communication or if we find it otherwise appropriate, we will also routinely sign+encrypt emails that we send out, generally irrespective of their content.

The author's main key (0x944890C4) should be used as the primary encryption target when communicating with Sven. Note that this is key is now also used on Sven's mobile device, as it is stored on an NFC-enabled security token. To this end, new subkeys are been deployed since July'16, so please refresh your keyring. The older, dedicated mobile key (0xA45F477B) has been obsoleted/revoked.

In addition, we use a dedicated key for our FSFE account (0x80F8AD6C) whose primary key is kept 'offline' with the day-to-day subkeys being stored on the author's fellowship smartcard.

We are generally happy to verify the above-mentioned fingerprints in personal meetings and to engage in keysigning activities. You should not solely rely on the information in Fig. 2 to establish the authenticity of the author's key, even despite your connection to sven-radde.de is encrypted using SSL.

Social media

In addition to sven-radde.de, we maintain social networking profiles on  XING and  LinkedIn that you can use to get in touch with the author professionally and personally.
Alternatively, feel free to connect using or  Facebook or -if need be- the author's virtually inactive  Google+ account.

You may also be interested in Sven's profile pages with the  FSFE and the  Scrum Alliance.

Sven can also be contacted by using the  Threema-ID 9H99ZMCX or the  Telegram user sven_radde. Request a mobile phone number to connect through  Signal and even  WhatsApp.

Curriculum Vitae

For the sake of legibility, this section gives only a brief résumé of the author's work and education experience. A complete CV can be provided on request.

Related Work

Jorge Cham [Cha97] presents a long-term study about the lives of Ph.D students. As far as the empiric soundness of their study is concerned, we find that anecdotal evidence from our own experience appears to support some of their conclusions. However, we would clearly prefer if their alternative presentation [Cha13] was made the default view.
In addition, we found the established periodical of Scott Adams [Ada14] to share a similar applicability to our current professional experiences as Chams work displayed during our academic career. Their work appears to us as a more application-oriented approach than the one described in [PH98].

The "SCIgen" paper generator by Stribling et al [SKA05] is able to automatically produce web pages (and even PDFs) that appear very similar to this website. While we certainly appreciate the generative approach of the authors, we find that their reliance on context-free (type-2) grammars severely limits the coherence of their results (on the other hand, this may be their exact intention). By contrast, sven-radde.de is not restricted in this way. In fact, we believe that not even unrestricted type-0 grammars may be able to fully express this work in its entirety.

Since 2006, Munroe [Mun06] publishes a periodical about romance, sarcasm, math, and language. He also occasionally features volumes about academia, science, and IT, such as in [Mun09, Mun10]. We find that, within the confines that are self-inposed by the chosen presentation format, his work is very inspiring.

Schönberg presents in [Sch13] his personal website in a design that is even more spartan than our own, with a point being made of a very literal interpretation of the concept of a hyper-"link". We found his work a good starting point in creating our website, but felt that a stricter adherence to academic structuring principles was in order for sven-radde.de, along with a slightly more modern presentation.

Regarding our own publications, we describe a system to verify documents using temporal description logics in [Rad05]. Radde, Gordienko and Freitag present an interactive language learning platform in [RGF06], which Ehrlich et al later extended in [ERPF07]. [BRF07, RBF07] describe early steps of the recommender systems research group around Radde, Beck, and Freitag towards a dialogue-oriented recommender system using a utility-based recommendation approach. A first conceptualisation of the "big picture" was sketched in [RF07]. Radde et al present an approach to generate an inference engine based on Bayesian networks automatically from a domain description in [RKF08], which [RF10] completes by describing how the output of the inference engine can then be used to recommend products. The domain (meta) description, with special attention to model maintenance, is presented by Radde, Zach, and Freitag in [RZF09]. Finally, we conclude our research efforts on the topic of recommender systems in [Rad13].

Conclusion

In this article, we have presented the personal website of Sven Radde. Apart from providing some news, we focused on presenting a contact form and showed a CV and the author's publications. The entire process of creating this website supports our initial claim that is possible to combine at least the following three benefits when building websites: create content that is at least modestly useful to the general public, experiment with modern web engineering technologies, and have fun along the way.

Our future work will focus on elaborating on the findings of this article, expanding it as we do so. In particular, amongst other things, we plan to enhance the security of the contact form by incorporating Javascript/OpenPGP-based end-to-end encryption techniques, provide convenient BibTeX-files for our publications, and to provide our news in alternative representations, such as RSS.
