We are very excited to be working with two fantastic GSoC contributors this year: Yutan Yang (@tarotaroyoung) and Zhenglin Li. Learn more about them at sqlancer.github.io/blog/gsoc….

CERT provides a new angle on the difficult problem of identifying relevant performance issues in database systems!
How can we automatically and efficiently find performance issues in databases? We propose CERT, a novel black-box technique: arxiv.org/pdf/2306.00355.pdf. Our key idea is to test them through the lens of cardinality estimation - a more restrictive query should return fewer rows.

And of course @ilyasergey! Co-advising opportunities also available!
Interested in PL/SE/FM but didn't apply for a PhD in the Autumn? The deadline for PhD applications @NUSComputing (Jan 2024) is June 15!
Apply if you want to be a part @nus_plse team and work with world's top researchers such as @mathur_umang, @RiggerManuel, and @AbhikRoychoudh1.

Next #ICSE2023 Distinguished Paper is "Testing Database Engines via Query Plan Guidance" by Jinsheng Ba and Manuel Rigger.
Attend the session on Testing of Database and Low-Level Software on May 19 at 11am to hear the details of this work!

Can ChatGPT replace database system testing tools like SQLancer or SQLsmith? An interesting read on an experiment by the @StarRocksLabs community. cc @CelerData celerdata.com/blog/chatgpt-i…

Excited and thankful for this recognition, especially considering that this is the first work authored solely by members of the @test_nus lab! Perhaps a good time to advertise that the lab has open positions (including postdocs).
Thrilled to obtain my second ACM SIGSOFT Distinguished Paper Award with @RiggerManuel! We'd like to thank the reviewers and PC chairs from @ICSEconf for this nice recognition! The number of found bugs keeps increasing!

Our paper "Testing Database Engines via Query Plan Guidance" was accepted at @ICSEconf (3x accepts!). The core idea is to steer automated testing towards unseen query plans for finding logic bugs. We found over 50 unique, previously unknown bugs. Stay tuned for the preprint!

It was great to have @RiggerManuel giving the invited talk "Towards Correct and Reliable Data-centric Systems" to our Security Research Group at @cis_unimelb. Manuel presented his impactful work SQLancer & recent ICSE'23 paper on Query Plan-Guided DBMS testing cc @JinshengBa 1/n

The paper has been released!! jinshengba.me/assets/pdf/qpg…
We already integrated our Query Plan Guidance (QPG) approach into SQLancer (see github.com/sqlancer/sqlancer…). Feel free to give it a try! I also gave a talk on QPG at Tsinghua University, hosted by Yu Jiang, earlier today and received insightful questions and feedback!

Philippe proposes multiple cursor support for structural code editors in his Onward! 2022 paper (co-located with @splashcon) titled "Forest: Structural Code Editing with Multiple Cursors". Please check out his cool online demo, GitHub project, and paper!
Try out structural editing with multiple cursors on forest.walr.is In our paper we investigate this unique combination and its potential to replace simple refactoring scripts arxiv.org/abs/2210.11124

So excited to get this award! If you want AFL to find memory errors 3x faster, don't hesitate to try our code out (github.com/bajinsheng/ReZZan).

Please retweet! The National University of Singapore is hiring in Software Engineering. We have open tenure-track (listserv.acm.org/scripts/wa-…) and educator-track (listserv.acm.org/scripts/wa-…) positions. I'd be excited to welcome you as a colleague!
