I am Ms. Molly Stewart-Gallus.
I guess right now I'm just working on my portfolio.
I have personal interests in formal methods but mostly have professional experience in web development. I'm most looking for stability and flexible work hours in job positions.
I have a personal interest in formal methods but mostly have professional experience in web development, system administration, advertising and analytics. I would strongly value flexible work hours or part time positions and would also prioritise stability and work-life balance. I don't want to go home on Friday and get a call on the weekend that something is broken.
In 2023 I have been exploring porting my poetry blog over to Gatsby. Mostly things have been very smooth but I have found the biggest problems to be Gatsby's lack of documentation. I can implement missing features I know about. I can't work around bugs that have not been documented. I'm not a fan of GraphQL per se but I can see the advantages of a unified abstraction over different data sources.
Also the tutorial documentation for Gatsby gives oversimplified and fragile designs for cases like blogging. The suggested designs don't work for cases like multiple source formats. Just as a Markdown plugin might process file nodes into Markdown nodes you want to implement your own code processing Markdown nodes into a custom type of nodes. This isn't really a flaw with Gatsby that the tutorials give the simplest but most fragile examples.
I have found React components to be less problematic than I initially expected. I expected lots of weird problems due to the abstraction over top the native architecture of the web. I haven't really found such problems to be the case so far although my website is relatively simple.
MDX, a Markdown processor lets you insert React components into Markdown, is interesting but has some major caveats that make it a little awkward sometimess. In particular, while MDX is probably well suited to writing ad-hoc websites and landing pages MDX is a little less useful for highly structured content like blog posts.
In 2022 I was have been mostly working on my bizarro poetry blog and relearning modern web development. I have found using Jekyll to be very copacetic. The biggest hiccup was figuring out how to implement a search page which I solved by integrating pagefind into my blog.
It has been really fun learning about fluid web typography and other advanced techniques. Fonts are definitely a headache online though.
I'm a bit of a perfectionist so my special interest for 2022 has been accessibility. Learning how to use a screenreader has been eye opening. I found it easiest to get started with Android TalkBack. Accessibility is very fiddly but makes for satisfying design problems to tetris in the most amount of information with the least amount of noise.
Most of my blog problems were fairly typical except for figuring out how to markup poetry appropriately. A fair bit of hacks were required to obtain the appropriate sort of hanging indent presentation and to obtain the appropriate pauses between sentences. If you're not careful with the markup the lines of the poem can run together or worse the words can. In the other direction, marking up a poem as an ordered list might lead to a lot of noise. Hearing "line m of n" every single line of a poem might be a little messy.
In the past I was working on formalizing a small amount of category theory in Coq.
I'm playing around with type systems and formal methods right now and I'm hopeful category theory can help with this. I've been trying to figure out how to make internal languages for many types of categories. I've started on some ideas to work within double categories like Rel.
I have a hunch you can generalize graded monads and adjoint functors for a sort of graded Call By Push Value which ought to be useful for a compiler IR to simplify optimization.
I got heavily into category theory for a while. I am no longer convinced it is so simple to compile computer programs to a categorical intermediate representation. But a start of an effort towards this might be this project which compiles a continuations based language to co-closed categories in a manner dual to compiling the STLC to closed categories. Basically it's dual to the paper Compiling to categories by Conal Elliott. I also found tagless final style is very clean for parametric higher order abstract syntax.
I have found category theory very interesting although it does have some weaknesses with respect to variable binding and higher category theory. Category theory tends towards a very combinatorial sort of style which makes some things very verbose that would be much clearer with name binders. Unfortunately parametric foundations allowing manipulation of name binders are kind of complicated. The other big hurdle with category theory is higher categories: categories of categories. Very quickly higher category theory gets messy to play around with in an actual theorem prover. I'm not sure if these problems are fundamental or someone smarter than me can come up with solutions.
I've also been playing with technologies like PLT Redex and Makam (a dialect of Lambda Prolog) for rapid prototyping of programming language interpreters.
You can see a tiny demo language in PLT Redex here
A little language in Makam here . Makam works great for simply typed languages but full dependent types are way too complicated in any implementation.
I got interested in compilers and interpreters for a while. I played a bit with effect systems like Call-By-Push-Value (basically ANF) and simple functional optimizations: https://github.com/mstewartgallus/hs-callbypushvalue https://github.com/mstewartgallus/compiler-2
I also played a little bit with GraalVM but I found it too complicated for initial experimentation. Also GraalVM had troubles with tail recursion at the time which made it hard to implement functional languages. Cadenza for example went through hoops I didn't want to bother with to optimize tail calls.
I got heavily into low-level details of the JVM for a while. I learned to use ByteBuddy and invokedynamic to insert dynamically optimizable spots into a Java program.
I got heavily into lock-free programming for a while and played with making a more efficient unfair lock implementation based on MCS Locks that uses a stack instead of a queue. I also tried formalizing a little bit of it in TLA+.
In the past I got into hard real-time and safety critical stuff for a while. I experimented with breaking a program into separate processes some of which are verifiable in a safe dialect of Ada SPARK. The lock-free queue is probably broken. I didn't really get how Ada SPARK was meant to handle concurrency.
