Our paper "Empirical Evaluation of Frequency Based Statistical Models for Estimating Killable Mutants" on evaluation on models for estimating equivalent and killable mutants were accepted by ESEM 2024. The paper is here. #ESEM2024 #Equivalentmutants #mutationanalysis
I am visiting ANU Canberra on Friday. If you are around, and is interested in what I do, please come talk to me.
Parsing JSON is indeed a minefield. However, a commenter in HN has a suggestion: Use postscript instead of JSON. It has a binary format, has comments, and generally looks much better. Here is their provided example:
<<
/first_name (John)
/last_name (Smith)
/is_alive true
/age 27
/phone_numbers [
<<
/type (home)
/number (212 555-1234)
>>
<<
/type (office)
/number (646 555-4567)
>>
]
/spouse null
>>And I agree, it is much better than JSON. There are many other interesting things to like here. For one, the keys are symbolic. There is only one character `/` indicating the keys in a dictionary (indicated by `<<`). This reduces the visual clutter to a great extent. Using `<<` for dictionaries is also great. Dictionaries are one of the largest units in such formats containing data, and it is better to use two characters for their delimiters. By using `()` for strings, it provides a starting and ending delimiter for strings, and is better visually parsable than `"`. There are no commas in arrays. or dictionaries, removing the question of trailing commas. Overall, PON (Postscript Object Notation) is much better designed than JSON for human readability.
Are you attending the Singapore Summer School on Fuzzing? Here's what my students and I have planned for Monday, fitting into more great talks and tutorials by Abhishek Arya, Marcel Böhme, Lim Min Kwang, Mathias Payer, and
Thuan Pham. Details at https://fuzzing.comp.nus.edu.sg
I am co-founding a new startup! #InputLab creates test data for thousands of formats from electronic invoices to retail orders, covering all input features. We just passed the initial evaluation toward up to 800k€ public funding to start as a #CISPA spin-off in September.
We are #hiring – notably test experts – and we are looking out for #collaboration partners and early #adopters from industry and public service. Check us out at https://inputlab.net! #startup #XML #softwaretesting
Is fussing the Australian spelling for fuzzing?
One great thing about LLMs such as GPT is that I no longer have to suffer through the very condescend "Oh you are asking for X, but surely you meant Y?" followed by closing the question as duplicate/irrelevant etc.

Thank you Naveen and Deb from Macquarie cloud services for the wonderful talk at SOFT3202 today!
