• klog - plain-text time tracking tool

  klog is a command-line time tracking tool built around a human-readable plain-text file format. Rather than storing work records in a proprietary database, it keeps the underlying information easy to inspect, edit, version, search and process with ordinary text-oriented tools.

  The format supports dated records containing durations, clock-based time ranges, summaries and tags. klog then provides commands for evaluating these records, producing totals and reports, filtering data and converting it into forms suitable for further processing.

• Pixcil - pixel art editor with an almost infinite canvas

  Pixcil is a pixel art editor built around an almost infinite canvas. Instead of limiting the workspace to the final image bounds, it provides surrounding blank space that can be used as a scratch area, temporary colour palette or working buffer while constructing artwork.

  The central frame represents the image that will be exported. Pixcil can also treat neighbouring frames as part of a larger structure: vertical frames can represent layers and successive horizontal frames can act as animation frames. On Linux, Pixcil can be used through its browser-based interface or from its Visual Studio Code extension.

• Atomdrift Scan - malware and software supply chain scanner

  Its analysis pipeline extracts and unpacks content, identifies capabilities and behavioural characteristics, and converts the findings into a common feature representation. Detection rules, known-good and known-malicious hashes, AST analysis and LightGBM model ensembles are then used to assess the sample. Dependency relationships and discovered references can also be followed during analysis.

  Atomdrift Scan provides JSON output for integration with scripts and automated workflows. Separate exit codes distinguish benign, suspicious and hostile results from analysis failures or incomplete rule sets. Detection sensitivity can be adjusted, rule updates can be controlled, and an optional LLM facility can provide additional interpretation of findings and assist with selected edge cases.

• bbl - command-line Bible reading and searching tool

  The program is particularly useful for comparing translations in different languages. Users can specify several Bible versions in the same command and display their contents together, making it easier to examine differences in wording.

  bbl uses Kotlin Multiplatform and Kotlin/Native to provide native command-line executables. Bible translations are installed separately as downloadable packs, allowing users to keep only the resources they need. Once downloaded, scripture texts can be read and searched offline.

• bibtex-tidy - clean and format BibTeX bibliography files

  BibTeX files obtained from publishers, academic databases and reference managers often differ in their field ordering, capitalisation and spacing. bibtex-tidy addresses these inconsistencies without requiring references to be edited individually.

  The program can be run from the command line or integrated into automated workflows. A browser-based interface is also available. Its focus is on cleaning existing bibliography data rather than collecting research papers or managing a reference library.
