Prof@SCS@CMU, scientist, software engineer, “heartless wench”, mama. It's pronounced "Le Gwess". Mostly academia, tech/SE, PGH. She/her

I’ve been lurking for a bit, but with the influx of academics, good time for a quick (re-)intro? CS prof at Carnegie Mellon, specialty Software Engineering, especially all kinds of code transformation/program repair (so yes, a lot of AI codegen these days), plus SE4robotics sometimes. 1/

Incredibly honored to receive the ACM International Conference on the Foundations of Software Engineering 2025 Test of Time Award honorable mention for our work on overfitting in automated program repair. with Ted, @clegoues.bsky.social, Earl.

Hoping this isn’t a sign of a streak, as the second conference in a row where my travel home is fubar (bumped from first flight; still technically possible to make my second, we’ll see).

Am accepting thoughts and prayers at this time.

SUP fellow yinzers flying back from Cancun tomorrow: let the record show that I DID pay an extra $120/ticket to carefully select seats such that my spouse and I were seated next to our 4 and 6 yo minor children, and it was American Airlines that decided to separate us. 🙃

I dearly wish that the MSM would give Ted Cruz’s stupid list the primetime mockery coverage it deserves. Turns out if you search for the word “inequality” you get….Math proposals. Very woke and neo-Marxist. 🙄

all I know is that had President Biden forced out the FAA chief under pressure from his top adviser and his corrupt motives, and then the next week there was a plane crash that killed more than 60 people, Republicans would be howling that it was an impeachable offense.

Apparently all the PhD researchers holding prestigious NSF-funded research fellowships are having their salaries withheld until some unspecified time when the leadership figures out how to eliminate any grant funding that doesn’t align with the president’s political ideology.
It’s official: all funding requests made on Tuesday by postdocs for their salaries have been unilaterally rejected by NSF.

Not gonna lie I did kinda expect our Democratic politicians to have something like a plan to counter the 920-page detailed fascist blueprint that was published in April 2023

Void shout: want a student to run experiments via OpenAI. Can't get to Tier 2 until 7 days after buying $50 credit. Can't get to 3 until actually using $50, waiting 7 more days (it's kinda hard to spend $50 at Tier 1, for the record). Can't add more than $50 at once. Their "support" is ChatGPT. 1/

In professional news: one of the things Biden signed his last week of office was a recognition of a set of PECASE awardees. Unbelievably honored (not to mention completely dumbfounded) to have been included on that list. 1/

Check out what my soon-to-graduate student Kush has been up to with the FAIR team! I particularly like how TestGenEval incorporates multiple metrics of test suite adequacy. 😊
Thrilled to announce our new work TestGenEval, a benchmark that measures unit test generation and test completion capabilities. This work was done in collaboration with the FAIR CodeGen team.

Gave the last lecture of the semester yesterday, so of course 6 hours later I was down with a chest cold, and as of today/next day, I’ve totally lost my voice. #proflife

In parenting wins, I’m pleased to report that my 3-yo son’s consistent, natural, uncoached/unprompted reaction to seeing a cybertruck in the wild is to burst out laughing, point, and say, “that’s so silly!”

BTW, if you’re interested in leakage in LLM-based SE results — this other paper doesn’t focus on leakage, but takes a bit of a side quest on the subject, related to the BigVul dataset and vulnerability detection.
We have other recent results on LLM-based security vulnerability detection that includes similarly alarming indications of leakage on BigVul, even though that’s not the main point of the study…(s/o to the student, Aidan, not On Here.)

So…yeah…we may have a problem. 😅 /fin

I'd like to thank that one student in the corner who nodded along with me all semester. You make it all possible.

And now that we’re all here, some work!🚨 Are Large Language Models Memorizing Bug Benchmarks? 🚨
There’s growing concern that LLMs for SE are prone to data leakage, but no one has quantified it... until now. 🕵️‍♂️ 1/

I’m not sure how active everyone is yet, but it’s nice to see what feels like a critical mass of CS/SE/PL academia moving over here.
