GENERAL INFORMATION

Administrivia

• Guido Salvaneschi

– Best way to find me is by email – salvaneschi@st.informatik.tu-darmstadt.de – Office A222 – Group of Mira Mezini

Intro

• Introduce students to the core techniques of

scientific work

– Give a scientific talk – Process of writing and publishing research papers – Review a paper

• Learn an advanced topic on PL

– Compare and evaluate existing solutions

Timeline

• Paper submission: June 11th
• Reviews submission: June 18th (1 Week!)
• Feedback meetings: June, Week of 22nd through 26th
• Camera ready: Friday, July 3rd
• Seminars: Friday, July 10th

Start Early!

Guidelines and Suggestions

• Find new references

– Try not to summarize everything that's written in references or in the references' references.

• Be complete in the bibliography, deep in the analysis
• Tell a coherent story about one aspect of the topic.
• Please present technologies, with your own words

and your own examples.

– E.g. : the same running example through the paper

Reviews

• A summary of the paper

– To demonstrate that you read and understood

• Suggestions for the author, regarding both content

and presentation

– Be realistic and concrete

• A list of the major positive and negative issues

– Honest! mainly used to grade the reviewer, not the paper

Grades

• Paper 40 %
• Talk 40 %
• Reviews 20 %
• Once more. Tell a nice story. Compare things. Find

advantages and limitations. Provide examples in different cases.

– Papers are there to read – This is the value that you add

Where to start

• Send me an email with your name and a list of 3 topics

– Order by preference. – Or consider synergies with DAIMPL

• Check the details on the course website.

– Time slots for seminars – Paper length and format – …

• Topics will be assigned
• We provide you some references as a starting point

TOPICS

.NET Reactive Extensions and Bacon.js

• Data-flow programming model

– Event streams – Everything is Observable – C#, Java, Scala, Javascript – Asynchronous – Functional combinators

var suggestion1Stream = close1ClickStream .combineLatest(responseStream, function(click, listUsers) { return listUsers[Math.floor(Math.random()*listUsers.length)]; } ) .merge( refreshClickStream.map(function(){ return null; }) ) .startWith(null);

Testing for event-based systems

• Map-reduce

– Events can be async – Nondeterminism!

• How to explore the whole space ?

Omniscient debugging

• What if debuggers can go back in time?
• Register ALL events

– Performance / memory issues

• Navigate back in time

– Find the root source of a bug

Programming models for massive data processing

• Map-reduce

– Huge amount of data e.g., from the Internet require efficient processing – Formulation in terms of basic operations (map, reduce) – Highly-optimized backends, e.g. clusters, clouds, etc… – Extension to the basic model: Twister, HaLoop, Spark,…

• Incremental approaches:

– Not only batch processing: view maintenance-like systems
