Five Years as Editor-in-Chief of Communications
This is my last editorial as Editor-in-Chief of Communications, so it is a moment to share learnings and, of course, to reflect on accomplishments.DEPARTMENT: Editorial
Our ACM Community
As we celebrate ACM's 75th Anniversary this year, it seems a fitting time to consider the community that ACM has fostered.DEPARTMENT: Cerf's up
Digital Synergy
Inventing an imaginary company helped me imagine how powerful it can be to have data available that permits fact-based analysis of business performance, projections for future business operations, and understanding of the marketplace …DEPARTMENT: Letters to the editor
More on Computing's Divided Future
Thank you for addressing the danger posed by the current Chinese government's imperialistic ambitions, using every tool at its disposal, including technology and foreign visitors (January 2022 Communications Editor's Letter). …DEPARTMENT: BLOG@CACM
The Role of Math in IT Education
Andrei Sukhov considers why and how the foundations of teaching mathematics for information technology specialties need to be revised.COLUMN: News
Always Improving Performance

Technical Perspective: The Compression Power of the BWT
"Resolution of the Burrows-Wheeler Transform Conjecture," by Dominik Kempa and Tomasz Kociumaka, finally settles the question of how well r in the BWT captures repetitiveness.Resolution of the Burrows-Wheeler Transform Conjecture
In this paper, we show that r =(z log2 n) holds for every text. This result has numerous implications for text indexing and data compression.
Technical Perspective: Computation Where the (inter)Action Is
"SoundWatch," by Dhruv Jain et al., provides an example of HCI research's vital role in designing architectures that trade off different computational capabilities and latencies.SoundWatch: Deep Learning for Sound Accessibility on Smartwatches
We present SoundWatch, a smartwatch-based deep learning application to sense, classify, and provide feedback about sounds occurring in the environment.COLUMN: Last byte
