Technical Perspective: Building a Safety Net For Data Reuse
The authors of "Guilt-Free Data Reuse" show there is a way to construct a safety net that goes around a fixed dataset so that it may be analyzed interactively without...

Guilt-Free Data Reuse
In this work, we initiate a principled study of how to guarantee the validity of statistical inference in adaptive data analysis.

Technical Perspective: Data Distribution For Fast Joins
What is the most drastic way to reduce the cost of communication for parallel data processing algorithms? This is the question studied in "Reasoning on Data Partitioning...
From Communications of the ACM
Reasoning on Data Partitioning For Single-Round Multi-Join Evaluation in Massively Parallel Systems
We introduce a framework for reasoning about data partitioning to detect when we can avoid the data reshuffling step.

Technical Perspective: Cleaning Up Flaws in TLS Implementations
One unfortunate fact about protocols is that as they get older and applied to more scenarios — and TLS is used basically everywhere — they tend to gain weight....

A Messy State of the Union: Taming the Composite State Machines of TLS
We systematically test popular TLS implementations and find unexpected transitions in many of their state machines that have stayed hidden for years. We show how...
