Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Functional Pearl: A SQL to C Compiler in 500 Lines of Code

Tiark Rompf, Nada Amin

We present the design and implementation of a SQL query processor that outperforms existing database systems and is written in just about 500 lines of Scala code - a convincing case study that high-level functional programming can handily beat C for system ...

Style Checking With Scala.Meta

Eugene Burmako, Mathieu Baptiste Demarne

In many companies, code reviews are big parts of the day-to-day life of an engineer. Some can argue that the time spent on someone else’s code is time that some cannot spent on her or his own work. Code reviews usually allow to find two kinds of issues. Th ...

Java and Scala's Type Systems are Unsound: The Existential Crisis of Null Pointers

Nada Amin

We present short programs that demonstrate the unsoundness of Java and Scala’s current type systems. In particular, these programs provide parametrically polymorphic functions that can turn any type into any type without (down)casting. Fortunately, paramet ...

Improving Scalability of Symbolic Execution for Software with Complex Environment Interfaces

Stefan Bucur

Manual software testing is laborious and prone to human error. Yet, among practitioners, it is the most popular method for quality assurance. Automating the test case generation promises better effectiveness, especially for exposing corner-case bugs. Symbo ...

Common Subexpression Elimination in Dotty

Martin Odersky, Dmytro Petrashko, Allan Vincent Roger Renucci

Common subexpression elimination is a well-known compiler optimisa- tion that improves running time of compiled applications by avoiding the repetition of the same computation. Although it has been implemented on a low level such as bytecode, it misses mul ...

Interoperation between Miniboxing and Other Generics Translations

Milos Stojanovic

Generics allow programmers to design algorithms and data structures that operate in the same way regardless of the data used by abstracting over data types. Generics are useful as they improve the programmer’s productivity by raising the level of abstracti ...

Isolates, channels, and event streams for composable distributed programming

Martin Odersky, Aleksandar Prokopec

The actor model has been a model of choice for building reliable distributed systems. On one hand, it ensures that message-processing is serialized within each actor, preserving the familiar sequential programming model. On the other hand, programs written ...

Extending database task schedulers for multi-threaded application code

Anastasia Ailamaki, Iraklis Psaroudakis

Modern databases can run application logic defined in stored procedures inside the database server to improve application speed. The SQL standard specifies how to call external stored routines implemented in programming languages, such as C, C++, or JAVA, ...

Traversal Query Language For Scala.Meta

Eugene Burmako, Eric Beguet

With the rise of metaprogramming in Scala, manipulating ASTs has become a daily job. Yet the standard API provides only low-level mechanisms to transform or to collect information on those data structures. Moreover, those mechanisms often force the program ...
