The technology that changed the world – 50 years of Internet (course in German language)

The Internet is celebrating its 50th birthday. It has changed humanity in so many areas of life. But how does this "network of networks" actually work? We would like to show it to you on the occasion of our 20th HPI birthday and the 50th anniversary of the birth of the Internet. The course starts on 28th October 2019. You can register at

In 1969, the year of the first moon landing and the legendary Woodstock festival, no one knew that the network of just four connected computers in California would create an infrastructure that now connects four billion people worldwide. But, to a majority of users, even today little is still known about what the technical construction principle of the network looks like and how the data packets find their way through the interconnected individual networks to the computer of the receiver.

What awaits you in the course?

  • Week 1 - Digitization of the World (introduction, history, humans in the center)
  • Week 2 - Computer Networks (bits and bytes, LAN, WLAN, WAN)
  • Week 3 - Network of Networks, internetworking, internet protocols
  • Week 4 - Transport through the Internet
  • Week 5 - Internet Applications (WWW, e-mail, social media)
  • Week 6 - Internet and Web Security (digital identities, cybercrime, risks, precautions)

You can deepen some of the more fundamental and technically advanced topics related to how the Internet works in the optional excursuses.

Target Group

If you understand German and you are interested in how the arriving digital world works and also in the historical and social significance of developments, you have come to the right place to also understand the functionality of the Internet. Programming skills are not required.

See you on 28 October 2019. We look forward to having you in the course!

P.S.: Our course Introduction to Successful Remote Teamwork has just started a few days ago. It is still not too late to register, none of the deadlines have passed yet.

This course introduces you to helpful skills for making an idea tangible and testing it with potential users. We use a task-based approach to build these skills. You will learn to take an idea to the next level and build a simple prototype, plan a testing scenario and collect feedback. This MOOC builds on the 2018 “From Synthesis to Creative Ideas” course, but you can also take it as a stand-alone MOOC. The assignments are designed for individual work.

5 new openHPI courses & an innovative method of examination in May

Dear Learning Community,

Today we would like to introduce the next five openHPI courses on the future of computing, minicomputer, Design Thinking, business processes as well as IT security and an innovative feature that makes it possible to earn a "Record of Achievement" or "Qualified Certificate," something which can usually only be done in six-week courses.

How can we master the exponential growth of data?

As more and more unstructured data, such as the Internet of Things, is created and needs to be analyzed it is necessary to pursue new approaches in software development. The openHPI course “Future of Computing - IBM POWER9 and Beyond” deals with the provision of microservices, container solutions and cloud-based applications as well as new basic technologies, such as artificial intelligence, and blockchain technologies. Use cases are provided by the companies Vattenfall and Bosch. For the free online course, in addition to the regular Record of Achievement, a Qualified Certificate from the Hasso Plattner Institute can also be obtained. Universities are free to decide on the allocation of ECTS credits for students.

You can enroll in this Massive Open Online Course (MOOC) starting on May 1 here!

How can I build a remote control car or a monitoring system for plants by myself?

In the two-week online course “Wie programmiere ich meinen ersten Mini-Computer?,” starting on May 2 in German, two master students from the Hasso Plattner Institute introduce initial programming experience to young people. Twenty-three-year old Lisa Ihde and her fellow student Daniel-Amadeus Glöckner (24) show their participants how to readout sensors, to control motors and to actuate LED lights. Lisa and Deus assembled their openHPI course out of many different practical tasks. The level of difficulty increases, but the tasks can be finished independently, too.

You can enroll now via this link!

Design Thinking: Beyond Brockhaus Thinking

Design Thinking is an innovation approach that has evolved through the past 12 years from a university program at Stanford and HPI Potsdam to a globally respected and universally applied set of methods and tools for supporting and driving change towards a networked culture in organizations. The course “Beyond Brockhaus Thinking: With Design Thinking to a Networked Culture” starting on May 8 is an introduction to the core principles of Design Thinking. It explains the innovation method’s cultural impact and inspires us in actively using Design Thinking at the organizational level.

Please enroll here!

Business Processes: Modeling, Simulation, Execution

This year markets and rules of the economic system are experiencing dynamic change. In the English-language online course starting on 15 May: “Business Processes: Modeling, Simulation, Execution” the main concepts for describing and analyzing business processes and decisions will be presented. Experts from the companies Signavio (Decision Modeling and Simulation of Business Processes) and Camunda (Concepts and Methods for Developing Executable Business Processes) will also offer practical knowledge on the management of business processes. During the course, these providers grant free access to their respective software. For the free online course, you can also obtain a qualified certificate in addition to the regular certificate.

Registrations are possible via this link!

Security for your mail communication

E-mail is one of the most important communication mediums of our time. However, the technology leaves much to be desired in terms of safety. E-mail users can neither be sure that outsiders don’t read their messages, nor that they arrive at the recipient without any changes. Appropriate security measures - the so called end-to end encryption as well as digital signatures - have to be managed by users themselves. In the openHPI workshop “Communicating Securely Via E-mail,” starting on 12 June, you will be taught practical exercises to teach fellow readers how to send and receive encrypted and digitally signed e-mails using free tools.

We welcome your registration here.

Innovative examination offer

We are pleased to announce a new platform feature that is now activated:

Do not miss the start of the Cybersecurity Basics exam next week! The three confirmations of participation in the courses Datensicherheit im Netz, Digitale Identitäten – Wer bin ich im Netz? and Blockchain – Sicherheit auch ohne Trust Center (in German), which you can still attain, enable you to take this exam. Thereby you can earn a Record of Achievement or qualified certificate, which is normally only possible in six-week courses.

> Interested? Then please enroll in the course here. The next possibility is in November we are already accepting registrations here.

Enjoy your courses! We look forward to your much-appreciated feedback and hope to see you soon!

Best wishes, your Open HPITeam

Christian Willems Awarded “Learning Developer of The Year”

During a glittering gala evening at Park Plaza Westminster Bridge Hotel in London, Christian Willems, CTO of openHPI, was awarded Bronze as “Learning Developer of the Year”. The award represents the industry’s highest recognition for achievements in the field of learning technologies. The 45-member independent jury is made up of leading experts in learning and development.

Christian’s pioneering work has been decisive in shaping the MOOC platforms openHPI and openSAP. With enthusiasm and an abundance of good ideas, he leads a team of developers, PhD candidates, and students at the chair of Internet Technologies and Systems.

In recent years, Christian has developed a range of innovative features, which have not only advanced digital learning in the world of academics but also in that of business. “It is extremely helpful that we have a double perspective in our project – on the one hand we develop the platform itself, and on the other hand we are the openHPI course providers and can thus experience firsthand if something is not working optimally,” Christian said. At the same time, he underscores the team effort: “It is completely clear that this award goes to the entire team. Only with the bright minds here at HPI and our exciting innovation partners, such as openSAP, have we been able to come so far.”

We congratulate Christian on this amazing success and are very proud and happy to have him in our team!

News on openHPI: Course Start and new Platform Features

Dear Learning Community,

Today, we would like to present you our new mainframes course (in English) and introduce two new platform features which will hopefully make learning with our platform even more exciting.

The Role of Mainframes for Business Life

We would like to invite you to our new English online course “Mainframe – Crucial Role in Modern Enterprise Computing,” which starts on November 5. Prof. Andreas Polze (HPI), Prof. Philipp Brune (University of Applied Sciences Neu-Ulm) and Wolfram Greis (European Mainframe Academy) will lead you through the topic. In addition, manufacturer such as Fujitsu and IBM will contribute video lectures.

What is the course about?
Participants can expect an comprehensive and compact introduction to the mainframe technology with the aim of increasing its popularity. The course instructors want to illustrate that mainframes are a modern and future-oriented technology which provides some USPs compared to other platforms. Most people use mainframes in their daily life without being aware of it: Transactions such as withdrawals at a cash machine, credit card payments, and flight bookings are processed in the background securely and reliably by mainframes. Mainframes are also at work when the tax consultant service DATEV prepares 13 million wage and salary statements per month.

Who should attend the course?
The online course addresses everyone who is interested in the topic and brings with them prior knowledge in computer science and algorithms. We would like to address particularly young people who are currently undergoing training or studying.

Good to know
Please estimate a workload of about 6 to 8 hours per week. In addition to the regular record of achievement, participants can earn a qualified certificate in this course. The Hasso Plattner Institute recommends to other universities the allocation of two credit points for the certificate of achievement. In last year’s German mainframe course more than 4,200 participants were enrolled.

Interested? Then please enroll in the course here:

New Features on openHPI

We are happy to announce two new platform features, which are now activated.

Preliminary Score
All of you who until now waited impatiently for the publication of their test results, can look forward to this new feature. For all graded tests (weekly assignments, final exam) we changed the procedure. That means, when you submit your answers, you’ll instantly see your preliminary score, so you no longer have to wait until the deadline has passed. Details regarding the individual questions and explanations will be shown after the deadline has ended as usual.

Timeline Tip
Until now, you could only see the general deadlines for the courses you’d enrolled in on the dashboard, and the course-specific deadlines on the course details page. Now, you can see them with a timeline tip on the learning pages too. Just click on the alarm clock at the top right, and a drop down menu with all important dates will open.

Have fun learning! We are looking forward to your feedback and hope to see you soon in the course.

Best regards
The openHPI Team

Learning Ruby on openHPI

Dear Learning Community,

The programming language Ruby was introduced in 1995 with the aim of combining the best of both worlds: the world of functional programming and that of imperative programming. The programming environment Ruby on Rails enjoys great popularity, and it is used to develop fast, new Internet applications. On October 1, we start our new openHPI course Programming with Ruby (in German). We look forward to seeing you there!

What it’s about
In Week 1 you’ll learn to understand the syntax and the most important constructs of Ruby. In Week 2, participants will learn how to write actual classes. Furthermore, the course team explains how to write small, but useful programs into the command line (input, output, the reading and writing of files). In Week 3, participants are shown how bigger programs in Ruby are structured and split and how external libraries (so called Gems) can be integrated.

After taking this course you should be able to read Ruby Code and understand the syntax, try out the language on an interactive console, write scripts and smaller Ruby programs yourself, as well as structure and split bigger programs.

Who should attend the course?
Participants should already have experience in programming in other languages to successfully follow the course. Furthermore basic knowledge in English is useful as the key words of the programming language are in English.

Good to know
Like other openHPI programming courses, this course is very practical and contains a great many practical tasks. Upon successful completion of the course you will receive a certificate. Please estimate a workload of about 3 to 6 hours per week.

You can hardly wait to start programming? Then enroll here at:

Best regards,
The openHPI Team

Digitale Allgemeinbildung: Hier leben unsere aktivsten Online-Lerner

The openHPI team has examined where most of our learners, and especially the most active ones, come from.

The result: The majority of our 175,000 participants come from about 60 large cities all over Germany. But also in 15 German cities with less than 100,000 inhabitants, we noticed an important concentration of active online learners who use our courses on current issues in IT and innovation.

In this analysis of the regional use of openHPI, we not only looked at the absolute number of openHPI users per city, but related this value to the entire population of this city. In that way, we found out, for example, that the density of learners (i.e., the number of single learners per 1,000 inhabitants) is between 6.4 (Heidelberg) and 1.3 (Duisburg).

At the same time, it could be that a large city has relatively high number of openHPI learners, but they exhibit a low level of activity on the platform. We therefore calculated another indicator, which targets the actual learning activity per 1,000 inhabitants. Learning activities are calculated according to clicks on learning videos, self-tests, graded assignments, exams, and forum posts. Here, regarding learning activity the values are shown to be between 904 (Heidelberg) and 164 (Erfurt).

Southwest Germany leading in digital learning

Both rankings of 61 German cities where HPI e-learning offers are most widely used show large cities in southwest Germany leading the way. One reason for the high number of learning activities and the high density of participants per 1,000 inhabitants may be the concentration of prestigious IT companies and institutes.

We can also see this tendency clearly in the following table, which is categorized by city:

City Learning activities on openHPI per 1000 residents Number of openHPI learners per 1000 residents
Heidelberg Position 1: 904 Position 1: 6,4
Karlsruhe Position 2: 895 Position 3: 4,6
Mannheim Position 3: 858 Position 2: 5,5
Stuttgart Position 5: 685 Position 4: 4,6

Workshop on IPv6 starts on June 11

Dear Learning Community,

The Internet of Things compels us to think about new data communication regulations. In the 2-week online course “IPv6 in Modern Networks” (in German), which begins on June 11, network expert Wilhelm Boeddinghaus will explain to us the Internet protocol which is the new standard for data exchange in the network of networks.

What it’s about
With the growing number of devices communicating through the Internet, we will soon need many more addresses than those presently available in the current standard. No matter if we look at home automation, transport, or medicine – in numerous areas things communicate with other things over the Internet. For just one device, often a number of sensors feed their data into the network. To enable the Internet to grow even more, the new Internet protocol IPv6 was introduced which provides a lot more addresses than the former IPv4 protocol.

In this course, Wilhelm Boeddinghaus explains the technical basics for the introduction of the new Internet protocol, and he clarifies where we get the addresses from and how they are structured. Furthermore, he shows the concrete steps that need to be taken to define a strategy for successfully implementing IPv6.

Who should attend the course?
The course primarily targets network experts and system administrators from companies, public authorities, and academic institutions.

Good to know
You should plan a time allotment of 3 hours per week to complete the course successfully. In this course you can receive a confirmation of participation and a record of achievement (further information about the certificates). Participation in the course and exam is free.

Successfully presenting the future of digital learning in New York

More than 200 guests from business, science and politics discussed the future of digital learning with scientists from the German Hasso Plattner Institute (HPI) at the HPI MOOC Symposium on 4 and 5 April in New York.

At the Symposium at the Hudson Yards office, researcher David Joyner of the Georgia Institute of Technology spoke in favor of developing new methods that allow participants in open online courses to quickly retrieve the content they have learned.

During the symposium, David Joyner reported that learners occasionally have misunderstandings and that is especially important in the so-called Massive Open Online Courses (MOOC) to frequently review what they have learned. Lee Rubenstein, vice president of Business Development at the edOC MOOC platform, said it was critical for digital learners to be able to access their course from anywhere, via any device: "The learners need to be able to access courses from anywhere and on any device. Whatever we want the learners to do, we must put the opportunity in front of them."

Justin Reich, Managing Director of the MIT Teaching Systems Lab at the Massachusetts Institute of Technology, reported on initial research results on learning in open online courses: "If you set all metrics in relationship to each other, such as points achieved, number of quizzes taken, high activity in the forum, etc., everything is possibly related to each other". From this, the e-learning scientist concluded that whoever is willing to learn a lot, will also use more and more content. Regarding the necessity of the evaluation of the learning data, Reich said: "You can collect lots and lots of data and still not know anything about the learners."

Also American business representatives were interested in the latest research results and practical examples around digital learning. Karen Deal from Newport News Shipbuilding said: "Our company is undergoing a digital transformation and I‘m looking for solutions to accelerate learning so that we can adopt new technologies and new processes, so this symposium just opens up a lot of opportunity to be able to accelerate, not just limp along and teach people a few things, but to get them to learn together."

John Queenan, founder of Charged Up, praised the HPI symposium as a place where he was able to experience: "some great thinkers in terms of how to make learning more effective and have a greater impact on society." For young entrepreneur Joan Ai, who is currently creating a start-up in the NYU Steinhardt EdTech Incubator, the symposium of the Potsdam Institute was an enriching experience: "Not only did I learn so much about MOOCs, but also how MOOCs would be applicable to my business and the educational space in general."

At the symposium, HPI researchers presented innovative technologies that are increasingly changing the way people use open online courses. "We were able to successfully demonstrate how newly developed MOOC technologies can improve the experience of learning and innovation processes as well as cooperation in and between organizations," commented Prof. Christoph Meinel, Director of the HPI Institute in Potsdam.

The German HPI had taken up the USA MOOC trend in 2011 as the first educational institution in Europe and as a pioneer for German e-learning and has further developed it since 2012. At the New York Symposium in the SAP Leonardo Center, HPI scientists presented the peculiarities of their Internet education platform, openHPI. It also presented what distinguishes the two partner platforms of the World Health Organization WHO and the software group SAP. The symposium was also about analyzing, understanding and designing digital learning processes. In particular, aspects such as the evaluation of learning data and the use of game-typical elements to increase learning motivation and stamina were discussed as well as the future of open online courses for everyone.

From IT Law to Information Service Engineering - New Courses on openHPI

Dear Learning Community,

In April we will be offering two new courses on openHPI: Information Service Engineering (in English), a course on natural language processing and a course on IT Law for Software Developers (in German). This course will introduce some of the most recent developments in data protection.

Information Service Engineering – Begins on April 16

What it’s about?
In this 6-week course (in English) participants will learn the fundamentals of natural language processing as well as the basics of Linked Data-based knowledge representation. The course will be taught by Harald Sack, who was a senior researcher at the HPI for many years and is currently a professor at the Karlsruhe Institute of Technology (KIT). In today's world, access to and availability of information are almost unlimited. As a result, we need search engines and intelligent programs to process these vast amounts of data. It is crucial to achieve ever more precise, more complete, and more reliable results when searching for and linking knowledge. This is achieved, for example, by systems that detect and correct errors. In this course, Prof. Sack and his colleague, Dr. Maria Koutraki will introduce methods that enable the transition from raw data to well-structured knowledge. ”We will demonstrate how natural language texts can be analyzed using statistical models and machine learning, and how this information can be described with the help of formal knowledge representation.” Prof. Sack explains. He will also show how automated image and video analysis function, how handwritten messages are translated into machine-readable language, and how computers programs are able to read printed texts.

Who should attend the course?
This course addresses students of computer science, data and web scientists, and anyone who is interested in the combination of semantic search and machine learning.

Good to know
In addition to the regular record of achievement, participants can earn a qualified certificate in this course. The Hasso Plattner Institute recommends to other universities the allocation of two credit points for the certificate of achievement.

Please enroll here:

IT Law for Software Developers – Begins on April 9

What it’s about

Triple-Pack of Courses

Dear Learning Community,

We hope that you had a good start in the new year and look forward to accompanying you through many exciting courses. We would like to briefly present the first 3 of them - Linux for Everyone, Internet Security for Beginners, and Intrapreneurship - Make your Business great again.

Linux for Everyone (in German) - Course start on February 12

Unhappy with Windows or just interested in an alternative? In this 2-week workshop (in German) we will guide you step by step through the installation process of the Linux distribution Ubuntu, showing you how to configurate it and use programs. Besides practical use examples, we will also present the history and the context of the free software movement. Prior knowledge is not necessary.

Please enroll here:

Internet Security for Beginners (in English) - Course start on February 26

Already in the Sixties, American researchers were able to not only use computers as blunt calculating machines but to connect them to a broad network. This was the start of the Internet which, in the meantime, connects nearly four billion people and around 23 billion devices, (e.g., computers, smartphones and sensors). The network of networks has therefore become an attractive target for criminals. Around four million attacks are registered every day, (i.e., 50 per second). Although the economic damage around the globe is immense - and we are talking about 400 billion US dollar per year - only a small amount of resources is spent on Internet security.

In the 6-week course, Internet Security for Beginners (in English), learn the methods hackers use to break into computers and networks and how you can protect yourself. We show you typical attack scenarios, explain how data is transmitted on the Internet, and reveal the tracks we leave behind when we use our smartphones. Protect your digital identity and understand how the confidentiality of your data can be guaranteed. No previous knowledge required.

Please enroll here:

Intrapreneurship - Make your Business great again (in English) - Course start on February 26

Does this situation sound familiar? You have a great business idea, but do not dare to bear the risk alone and leave your current job. In this 6-week course (in English) learn how people with entrepreneurial spirit have changed a company and developed new products - even if the signs were bad in the beginning. We present you with the intrapreneurship concept and tools to support you in realizing your idea. You can look forward to illustrative field reports (e.g. by Bosch, SAP, AVL List and Signavio), a large tool box containing more than 20 tools—from the Ansoff matrix to the minimal viable product (MVP) and the stakeholder map, and practical exercises where you can directly use your newly acquired knowledge.

The course was created in a cooperation between the University of Economics Cracow, the FH Joanneum Graz, AVL List GmbH, and the HPI Potsdam. It was realized under the umbrella of the EU-funded project BizMOOC.

iOS App & Winner of the Competition "Favorite Learning Place"

Dear Learning Community,

Our competition “My favorite learning place” has just ended, and our jury of openHPI team members, students and design thinkers had the very hard task of deciding who from among the 60 submissions should be the winner.

The choice was in fact a very difficult one, given the large number of original, creative photos. Besides receiving wonderful vacation pictures from Croatia, Bali and Oman, we got drawings and photos from our international learners, e.g. from India, Vietnam, Ukraine, Switzerland, Hungary, the United States, France and Belgium.

Winner likes lying in the hammock while taking the openHPI courses

The first prize goes to Rike Ullenbaum (36), who is an expert for work and organizational psychology from Wuppertal. Rike is currently taking the Design Thinking MOOC and only started to learn at openHPI in 2017. The hammock photo she sent us shows how flexible, mobile, and, at the same time, comfortable learning with openHPI can be. The idyllic spot, at the very back of Rike’s garden, is a place where she can immerse herself in openHPI courses in absolute quiet.

Here you can download all 10 winning photos.

Watching openHPI videos offline - New download function in the iOS app

If you are using the openHPI app on your iPhone or iPad you maybe have already noticed: in the overview of all learning items you can now download the video lectures.

Protect your Privacy in Social Media – Course Start on October 23

Dear Learning Community,

In two weeks, the completely reworked new edition of the 2-week workshop “Social Media - What No One has Told you about Privacy“ (in English) will start on openHPI.

In the wake of the German parliamentary elections, fake news and the influence of social media is more relevant than ever. Dr. Anne Kayem, guest researcher from South Africa, shows in this workshop how fake news is spread and how users can protect themselves against the dissemination of false information about themselves. “Around 9 percent of the profiles of all facebook users are fake – these are around 83 million accounts,” says Kayem. Participants will learn more about this problem―called catfishing―and get to know methods of exposing catfishers.

No prior knowledge is necessary to take this course. The workshop addresses everyone who uses Facebook, Twitter & Co. for business or pleasure and who likes to know how to avoid data misuse and identity theft. Successful course participants will receive a certificate.

This teaser gives you a small taste of what to expect. Enroll now:

Subtitles in 10 languages are available, among others in German, Polish, Dutch or Russian. As you might know, state-of-the-art machine translation is not yet perfect. We are however convinced that the possibility to follow courses in a language that you don’t speak fluently offers a big potential to broaden your mind. We are curious and rely on your feedback, and we are working hard to give you machine translated subtitles soon for all of our courses.

We are looking forward to seeing you!

All the best

September dedicated to Algorithms and In-Memory Data Management

Dear Learning Community,

We are happy to announce to you two courses, starting on September 18, 2017:

“In-Memory Data Management” (in English), the iteration of the very successful course by Prof. Hasso Plattner, and “Mathematics of Algorithms” (in German), a brief introduction to the language of modern math that is behind every application in computer science.

“In-Memory Data Management”

What it’s about:
Businesses often face the dilemma of how to effectively retrieve and process data quickly in a way that best meets the growing demands of the market. In this 5th iteration of Prof. Plattner’s course, participants become familiar with a revolutionary database technology. Data is kept in column-oriented in-memory databases instead of relying on traditional row-oriented disk-based storages. The speed of information processing increases dramatically and overall performance improves. Thus, nothing more stands in the way of the analysis and comparison of big data.

Good to know:
No prior knowledge is necessary to take this course. This course addresses users who are interested in trends in the database and hardware environments as well as business professionals who come in contact with in-memory computing and HANA

Do you want to know more? Then enroll here:

“Introduction to the Mathematics of Algorithms”

What it’s about:
This 2-week workshop in German introduces the basic elements of computer science and explains, for example, what quantifiers and connectives are. The mathematical principles will then be applied in selected examples, and mathematical puzzles will break up the course and challenge the participants. For this course, too, no prior knowledge is required.

Interested learners can enroll in the course here:

We hope that these topics are of interest to you and look forward to seeing you in the course.

Best regards
the openHPI team

P.S. Until September 17, 2017 you still have the chance to participate in our competition. Show us your favorite place for learning and win a trip to Potsdam and a visit to HPI. --> Further information on the competition

Computer Science meets your Own Four Walls: Smart Home

Dear Learning Community,

After its great success last year, we have again decided to include a workshop Embedded Smart Home (in German) in this year's program 2017.

Embedded Smart Home

The 2-weeks course starts on July 3, 2017 and addresses all who are interested in new technologies and who have fun programming.

You can enroll in the course here .

What's it about?
Martin Malchow and Matthias Bauer, who some of you might already know from the preceding course, are eager to try out other new projects for the smart home. For instance, participants will learn how sensors can be used to control external actuators (e.g., a lamp or blinds).
"At the request of many participants from the last course, this time we want to also show how a camera can be externally controlled and monitored," said the course supervisors.

Good to know
Participants can program and manage their embedded smart home with a Raspberry Pi, an affordable minicomputer. We will use the Linux distribution system Raspbian and work with the programming language Python in the programming exercises. No special hardware components are needed to participate. All tasks can easily be performed on a device that is provided by the learning platform.

Would you like to brush up your programming skills before the course begins? We recommend the course "Learning how to program in a playful way" (in German), available in the archive mode. Participants who like to play around with their own Raspberry Pi at home, will get more information to prepare for the course before it officially starts.

See you soon in the course!

Dear Learning Community,

Study guidelines, good practice and recommendations on how to apply MOOCs, learn about opportunities for the use of MOOCs and discuss hot topics such as quality, business models or certification. For more visit

Digital technologies and new demands of learners and the labour market are the main drivers behind the process of changing the Global Education. However, several EU regions, higher education institutions and businesses appear to be not aware of the situation and might lose the connection to this rapid growth in the long term. Especially for the world of business, a huge potential lies idle.

The MOOC BOOK is realised under the umbrella of the EU-funded project “BizMOOC – Knowledge Alliance to enable a European-wide exploitation of the potential of MOOCs for the world of business”. “With BizMOOC, we want to encourage the modernisation of European education, generate a cross-border and cross-sector knowledge exchange on MOOCs in Europe and promote the acquisition of labour market key competences”, said Christian Friedl, coordinator of BizMOOC project.

For Higher Education Institutions, there are several benefits coming from the MOOC BOOK. First of all, MOOC BOOK offers answers to various questions related to how MOOCs address HEIs. The questions and answers are grouped into three main categories: MOOC basics, MOOC adoption and advanced MOOC concept thus targeting those new to MOOCs, those who have a little experience with MOOCs and those well-experienced with it. The next part of the MOOC BOOK is called needs and gaps to MOOCs which offers identification of needs and gaps for the application of MOOCs by HEIs. It is concluded by the State of the Art on existing MOOC knowledge with topics such as existing MOOC quality models or issues for MOOC recognition, certification and accreditation.

World of the business profits from the MOOC BOOK equally. Guidelines provide the extensive knowledge on applying MOOCs from external providers and applying self-produced MOOCs, answering questions such as what the potential costs are when employing the existing MOOCs by other providers, or what the options are if the business wants to provide MOOCs on their own. Similarly the next part of the MOOC BOOK offers the identification of opportunities of MOOCs for the business community. The final part may then answer any questions related to 14 relevant MOOC topics, for instance MOOC IPR issues, MOOCs and Human Resource Development or existing MOOC business models.

The MOOC BOOK also does include labour force/society as such. It addresses the society in general and provides information on MOOCs in general, learning on a MOOC and taking MOOCs further. What is the right type of MOOC and teaching approach for me, are the employers aware of MOOCs, how can MOOCs improve my skills – those are just some of the questions the MOOC BOOK answers. In the section for the society it also provides very interesting results from the society survey carried out with a range of citizens across Europe including students, non-formal/lifelong learners, the unemployed and employees in a range of industries.

Happy Easter!

Dear Learning Community,

Days are getting longer, and the time is coming when we can sit outside in the sun - the Easter holidays will be here before you know it!

Maybe, you have planned a short trip somewhere, or you want to spend an enjoyable time at home. Perhaps you even have the time and leisure to do some coding exercises. The openHPI Java team has done everything to make sure that you won't get bored. If you have not yet enrolled in the course "Object-Oriented Programming in Java", take a look at the content of the first 3 weeks, which is now available. You can still join the course community.

Java workshop - Introduction to a Java IDE

We are happy to announce the next Java course to all enthusiastic participants of the introductory course "Object-Oriented Programming with Java," running at the moment, and who want to learn more. In the 2-week workshop "Introduction to a Java IDE" Ralf Teusner and Tom Staubitz are going to dive deeper into the topic and explain how to use a Java IDE (Integrated Development Environment). For working with Java, just as in any other programming language, you need certain tools, such as a compiler, an interpreter and an editor. These tools are called the Integrated Development Environment.

Having learned the basic concepts of Java in the currently running course, we would now like to teach you in the following workshop how to implement your own programs.

So: Please mark the first of May in your calendar, the date when the Java IDE workshop starts. Everyone is welcome who has at least basic programming knowledge in Java. You can enroll here.

nanou - The new iOS microlearning app

As you know, we are steadily looking for new features that support learning. At the moment we are testing a prototype for microlearning. Some of you already have installed the app which is available for iOS (iPad, iPod Touch and iPhone) and only in the German language so far. The mobile application offers short video lectures based on your personal interests. Those of you who have already visited many openHPI courses might recognize the one or the other video. The video snippets of 3-4 minutes build on one another contentwise. Every time you watch a video, other videos are made available. You can rate the videos after having watched them and thus improve the recommendations. We have compiled more than 50 videos from openHPI and other sources for you.

Here you can download the app.

We are looking forward to your feedback! You will be invited to take part in a survey directly in the app.

Besides programming, you can learn a lot of other things on openHPI, for example how search engines or mainframes work, or how you can make your home smart. Here you can find the complete course calendar.

Best regards and happy Easter,
the openHPI Team

If you are not enrolled to the course, yet, you can do so here.

openHPI at CeBIT

The world's biggest computer fair, the CeBIT in Hannover, came to an end yesterday. Of course, openHPI was there, too. Enriched by a lot of new impressions and feedback, we are back now (a big thank you at this point to all the openHPI learners who came to see us there!). Federal Minister of Education Johanna Wanka, the Saxon Minister of the Interior Markus Ulbig and the ministers Meisch (education) and Schmit (labour) from Luxembourg came to visit HPI and got informed about openHPI and the other HPI MOOC platforms. Furthermore, a lot of school classes took the opportunity to learn more about the HPI and the course offer of openHPI. They especially liked the openHPI quiz in which the players had to answer 10 questions concerning the Internet and social media in a short time - the winner received an openHPI cup.

MOOC BOOK - A guideline on how to apply MOOCs

openHPI recently joined the EU project bizMOOC. Together with 10 partners from the whole of Europe we have summarized in a MOOC BOOK guidelines, best practices and recommendations on how to apply MOOCs. Especially for the world of business and for Higher Education Institutions (HEI) MOOCs have a huge potential, for example for training, marketing or recruiting purposes. Guidelines provide the extensive knowledge on applying MOOCs from external providers and applying self-produced MOOCs, answering questions such as what the potential costs are when employing the existing MOOCs by other providers, or what the options are if the business wants to provide MOOCs on their own.

Did we spark your interest? Here you can access the MOOC BOOK.

openHPI gets involved in the BizMOOC project

Dear Learning Community,

Recently, openHPI joined the European BizMOOC project.

We are glad about this opportunity to exchange our MOOC experience with colleagues and researchers all over Europe. We are aiming at merging our knowledge and making it available to all interested stakeholders.

BizMOOC - What is it about?

The project tackles the European challenge of enabling businesses, labour force and universities to increase their activities and exploitation (economies of scale) of the MOOC potential. This will be achieved by creating common standards on MOOCs by integrating the experiences from Higher Education and the business world. The most important result will be the open access MOOC Book, which provides recommendations, guidelines, methods and strategies. Moreover, we'll produce 3 pilot MOOCs focussing on topics such as entrepreneurship and innovation, of which one will run at We'll inform you in good time before the start.

The MOOC Book - Core of the Project

The MOOC Book is the free online resource to Massive Open Online Courses (MOOCs) for businesses, workforce and universities. It contains guidelines, good practice and recommendations how to apply MOOCs, opportunities for the use of MOOCs and hot topics such as quality, business models or certification.

What is the right type of MOOC for me? Where can I find MOOCs for certain topics? Do universities recognize learning done through MOOCs? Are MOOCs only an extra expense or also a possible new income source for universities? What are possible reasons for companies to provide MOOCs themselves? What are the technical requirements? This is only a selection of questions which are raised and publicly discussed in the MOOC Book.

Did we spark your interest? Here you find the full text. We are looking forward to your comments!

Best regards,
the openHPI Team

That's what our learners say

Dear Learning Community,

We regularly ask our users about their motivation to participate in the openHPI courses.
This time we spoke to Dominik Hausner. He is a computer science teacher, who often uses the openHPI programming courses directly in class:

"Around 120 students from our school have participated in the course "Learning how to Program in a Playful Way". They are very interested and enthusiastic about it and even spend their spare time to work on the tasks. Especially, the programming platform CodeOcean offers great didactic possibilities for beginners, which can rarely be found with other education software or student IDEs for computer science."

Do you also want to appear in this section and say a few words on your experience with openHPI? We are looking forward to receiving your statement and photo at

Java - More than a Programming Language

Dear Learning Community,

We are happy to invite you to our new 4-week openHPI course "Object-Oriented Programming in Java" (in German language) which starts on March 27. Here you find the trailer and the button to enroll to the course.

What is it about?

Java is one of the most popular programming languages in the world. It is particularly suitable to learn object-oriented programming (OOP).
OOP is a programming paradigm organized around objects, which are often modeled as an abstraction of real life.
Basically, this concept is closer to the human way of thinking than to the requirements of the machine.

Detective Duke and Robot Robin are the protagonists of the course. They will be accompanying the participants through the course and bridge the technical concepts to the real world. Robot Robin, for example, was modeled with specific qualities and capacities to solve the present case.

Step by step, the learners will experience the concepts of classes, objects and variables. How can problems be represented with attributes and methods?
Further topics of the course are constructors and loops, visibilities and inheritance.
Finally, we will have a look at modeling techniques and class diagrams.

The course focuses on practical exercises, which can be implemented comfortably in the web browser on CodeOcean, our integrated programming platform.

Who should attend the course?

The course addresses everyone who is interested in object-oriented programming.
You only need a computer with Internet access to take part. Previous experience may be helpful, but is no requirement.

The course is offered by an HPI team of 7 researchers and students.
We estimate the workload around 3-6 hours per week, depending on the previous knowledge.
Got a taste for Java? Then you already should schedule the following 2-week workshop "Introduction to a Java-IDE" in your calendar to deepen your acquired skills. We are looking forward to seeing you in the course! This workshop is also offered in German only!

Another course recommendation for March: Machine Learning

Have you already seen the course on Machine Learning (in German language) which will start on, our partner platform on March 20? During 3 weeks business experts, developers, researchers and users will present methods, tools and application fields of machine learning. Here you can enroll to the course which is offered by acatech (National Academy of Science and Engineering) in cooperation with DFKI (German Research Center for Artificial Intelligence).

Best regards,
The openHPI Team

That's what our learners say

Dear Leaning Community,

We'd like to regularly quote our learners at this point. Without you, openHPI wouldn't be the successfull learning platform it is.

The World Wide Web - How does it work?

Dear Learning Community,

We hope that you had a good start in the New Year! We are working intensely on the new course Web Technologies (in German) which will start on February 6, 2017. We would like to sincerely invite you all!

What is the Course about?

The World Wide Web is the most powerful application of the Internet. Online banking, Internet shopping and communication within seconds would not be possible in the convenient way we know today. In this course we would like to give you an overview of this technology, e.g. have a look at the identification scheme in the web (URI). We will explain how documents are requested and transmitted in the web (HTTP). Do you actually know what cookies are good for? What about how linking works? How do documents have to be structured to be read by machines (XML)? We'd like to answer all these questions in the course. Nowadays, websites are often very complex systems – entire application programs are offered in the browser. You'll learn the basics of web programming, databases and frameworks and get to know JavaScript which is used for example to implement effects on websites or Ruby on Rails which is used to carry out complex web projects. At the end of the course Prof. Meinel will talk about the effects of the Web on society and give advice about where users of this technology should be careful. Twitter bots, echo chambers or identity theft and other security aspects are only some of the topics which will play a role in week 6.

Who is the Course for?

The course is intended for all interested Internet user who would like to get a better understanding of the underlying technologies of the web. The only thing you need is curiosity, a bit of time, and Internet access - There are no pre-requisites.

Here you can enroll for the course on Web Technologies.

Highlights of 2017

Dear Learning Community,

As another year draws to a close, we'd like to seize this opportunity to sum up the highlights of 2016.

This was 2016

From smart home to digital health
In 2016, we were very pleased to exceed our course enrollment threshold of 300,000, with a 46% growth of 107,886 enrollments in total since January! Next to front runners such as Internet Security or How does the Internet work?, we also widened our scope to include several new topics.

Dr. Manuel Effenberg from the HPI School of Entrepreneurship (E-School) offered a 2-week workshop on how to create a successful IT startup. In addition, Dr. Matthieu-P. Schapranow, who is the "E-Health" Program Manager at HPI has just finished his lectures on the Code of Life - When Computer Science meets Genetics. Our statistics tell us that the course on Embedded Smart Home was highly popular. Perhaps because participants could dive into the world of smart home using their own raspberry pi and temperature as well as humidity sensors. Another newcomer, Lisa Ihde, who is an undergraduate student at HPI addressed our young audience with a course on designing your own homepage.

MOOCs for study
A lot has changed on the platform from a technical point of view, too. Probably the most significant new feature is the qualified certificate which went live in October 2016. This certificate which includes the participant's photo next to the typical course and grading information makes it possible for students to obtain credit points for MOOCs at their home university.

Android and iOS App
The Android app has been on the market for a while now already. iPhone owners can be joyful because openHPI announced news on the beta version of the iOS app last Sunday. For those of you who own an iPhone and want to test the app, you are welcome to provide us with your email address on the form available in the Advent MOOC (week 4).

Start of the Web Technologies course (in German) on February 6

Next year we will take off with a course many of you might already know. The Web Technologies course which was last offered in 2015 has been updated and extended with a variety of topics. We plan to spend one whole week discussing the "Web in Society", as this technology permeates our society in a profound way. We will have a closer look at phenomena such as formation of opinion and manipulation in social media, security in the Social Web and Internet of Things.

Have we succeeded in enkindling you interest? If so, please enroll here.

We wish you a merry Christmas and a happy new year! And if you are bored during the holidays take a look at openHPI. On December 24, on the Advent MOOC, we are going to lift the secret of the participants' favorite feature. How exciting!

Best regards,
The openHPI Team

Available now: Course Program 2017

Dear Learning Community,

What a nice advent surprise! The new openHPI course program is online now. In case you haven’t already seen it, here’s a short summary of what we are going to cover in 2017:

  • We'll start with a relaunch of the 6-week Web Technologies course (in German) which was last successfully held in 2015. The participants will learn how the World Wide Web works. Through this killer Internet application worldwide communication is possible within seconds.

  • April and May are "Java months". First, the openHPI team is giving a 4-week introduction to object-orientated programming combined with an exciting detective story. In the following 2-week workshop the participants can put to use what they have learned. Both courses are held in German.

  • Those who loved the search engines subject in the course Web Technologies, should have a look at the 2-week workshop How do search engines work. Dr. Ralf Krestel explains the basics of information retrieval (in German).

  • The next newcomer is a 6-week course on mainframes (in German). Nearly all big players work with these computers. Prof. Andreas Polze and other experts on the subject will present the architecture and characteristics of these mainframes.

  • The next course is for all hobbyists among you. In the 2-week workshop Embedded Smart Home we explain how you can control the illumination at your home using a raspberry pi and some sensors and actuators. This course is in German.

  • Another new topic that adds to the diversity is an Introduction to Algorithmics (in German). The 2-week course is a good preparation for the study of computer science. Computer science and mathematics are closely linked. For example, the search algorithms of Google are based on mathematical laws.

  • Next year we’ll again have what many of you have asked for this year: In-Memory Data Management, our long running course which has been in high demand since openHPI started (English, 6 weeks).

  • openHPI without a course on security??? In the relaunch of Social Media - What No One has Told you about Privacy, learners experience which risks lurk in social media and how they can protect themselves, for example by choosing the right settings (English, 2 weeks).

  • As usual, the last course of the year comes from the Semantic Web research group. How can we find useful information in the huge web? How can the meaning of information be accessed in an automated way and interpreted correctly? Prof. Sack will answer these questions in his 6-week course on Semantic Web Technologies (in English).

10 exciting topics - but who knows ... we have received your course wishes in the Advent MOOC, and the vote is yet to be decided.

Enroll now and don’t miss out on your favorite course!

You can find our complete course program here.

Best winter wishes,
The openHPI Team
