Pandoc is a universal markup converter written in Haskell that can convert between numerous markup formats such as Markdown, HTML, LaTeX, and more. It uses a neutral Haskell data type representation of documents and applies parsers to input documents to convert them to this representation before writers convert it to the target format. Pandoc's use of Haskell allows for type safety and leverages libraries like Text.Parsec to parse documents in a flexible way by treating them as structured lists.

Published in TANET 2018.
The reliability of distributed file system (DFS)
is a key factor to satisfy the service level agreement
(SLA) of cloud services. Nowadays open source
DFSs are adopted by more and more cloud services,
but lacks of reliability evaluation on them. To
concern with the issue, we report on reliability
characteristics of MogileFS which is one of major

improved schemes of MogileFS which corresponding
to failure patterns we identified from the observation.
Evaluations based on continuous-time markov chain
(CTMC) are also provided. This study contributed to
the current understanding of the reliability of DFS in
reality.

Language-agnostic data analysis workflows and reproducible research
This was a talk that I gave at CERN at the Inter-experimental Machine Learning (IML) Working Group Meeting in April 2017 about language-agnostic (or polyglot) analysis workflows. I show how it is possible to work in multiple languages and switch between them without leaving the workflow you started. Additionally, I demonstrate how an entire workflow can be encapsulated in a markdown file that is rendered to a publishable paper with cross-references and a bibliography (and with raw LaTeX file produced as a by-product) in a simple process, making the whole analysis workflow reproducible. For experimental particle physics, ROOT is the ubiquitous data analysis tool, and has been for the last 20 years old, so I also talk about how to exchange data to and from ROOT.

CAKE: Sharing Slices of Confidential Data on Blockchain
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.

- 5. ● One possibility: functions devoted to each type-to-type combination ○ markdownToHTML ○ HTMLtoEPUB ○ 12^31 possibilities ○ FUCK THAT ● Vastly better possibility? Reader --> Neutral Haskell data type --> Writer --> Converted document Possible approaches
- 6. ● Semi-stateful, non-opinionated REGEX machine ○ Accumulative — return (x:xs) ○ getParserState ○ modifyState ● Core functions ○ parse ■ parse parser filePath input ■ parse numbers "" "a,b,2,3" ○ many ○ skipMany ○ manyAccum ● type Parser t s = Parsec t s Text.Parsec
- 7. ● Neutral data types ○ Pandoc = [Block] ○ Block = [(Inline || Block)] ○ Inline ○ etc. ● Reader ○ Applies parsers to documents ○ Documents are treated as lists ● Writer ○ Converts neutral data type into document ○ Again, documents are just structured lists Basic flow
- 8. ● Readers/Markdown.hs ● Writers/HTML.hs ● Pandoc/Builder.hs Markdown to HTML
- 9. ● When doing big, complex things with FP, you're probably going to end up thinking in terms of lists ● Lists are infinitely flexible ● Hard to escape state entirely ○ ReaderState ○ WriterState ● Don't give up ● Force yourself to give a presentation at PDXFunc General lessons
