Jack Bendtsen's Personal Website

If you're reading this, you've arrived at the source code for the website itself! For more information, including why I developed this site the way I did, check out my blog!

Technical Features

Handwritten HTTP server loop, handwritten data structures
Thread per connection for sending and receiving, all processing done on main thread
Custom Markdown renderer

Doesn't follow the entire spec, but includes extra features not in the spec

Custom text/code editor widget, based on HTML canvas

Re-implements conventional editing features, eg.

Arrow movement (crtl+arrow for word movement, shift+arrow to select text)
Mouse input
Copy/cut/paste

DPI aware
Infinitely scrollable

SpriteWave

SpriteWave is an interactive tool for arranging images from 2D games.

About

This tool lets you extract tiles from inside of a NES, SNES or Genesis ROM and paste them into a separate window, where you can rearrange and recolour them to form an image, which can then be exported to PNG.

The interface is mostly driven by the mouse, with drag-and-drop being the main way to move tiles around.

Features

Tile rotation and mirroring
Palette and RGBA pickers
Colour transparency
Offset input data
Image exporting:

Flexible naming scheme
Image scaling

mash

A GPU-accelerated text file viewer and editor (WIP)

Muscles

Work-in-progress struct-based memory editor and analyser

Written in C++ with SDL, it is designed to provide an informed view of the current state of another process in real time, allowing the user to understand what the program is doing in terms of its variables (with types) within objects. Currently targets Windows and Linux.

TODO

Replace field formatting with type options

Bind formatting options like base and prefix to a type, the same way a type has signedness and size

Fix various C parsing bugs (eg. circular typedef dependencies)
Support for array values and string literals (across various features)
"Taskbar" feature to minimise/maximise windows
Mechanism for writing data back to the file/process
Develop an AST to allow for things like calculating addresses of objects, the first step toward tracking objects in containers and allocators

pistachio

A lightweight text-based application launcher

Pistachio is an application launcher for Unix-based systems that employ the X11 window manager. It lets the user run any program in /usr/bin or launch any file with their associated program, as specified by the configuration (see below). When the user types into the window that appears at launch, suggestions that match the typed text appear. These suggestions can be navigated using the Up/Down arrow keys, and be selected to run using the Return key.

Configuration

Upon launching pistachio, it looks for the configuration file ~/.config/pistachio/configuration. If not found, it will create a new config file at that location with the default program options.

Options

`font-path <full path to font file>`

Sets the font to be used.

The install script install.sh attempts to find the default monospace font using fc-match.

Tiny Android Template

For Android projects written in Kotlin and/or Java, using the latest AndroidX libraries

The purpose of this template is to give people the ability to write Android apps without having to use Android Studio or Gradle. When I picked up Android dev for the first time, I was struck by how frustratingly slow and janky these tools were to use, and that they seemed to only run at an acceptable pace on machines designed for gaming. However, I still wanted to write apps for Android, so I developed this template so I could continue my work without having to use an IDE or external build system.

Requirements

Java Development Kit (JDK)
Kotlin Compiler (optional)
Android SDK
7-Zip
Bash & Perl (Cygwin/MSYS if on Windows)

Does Not Require

Android Studio
Gradle
Apache Maven / Ant

AngioTool 2.0

This is a rewritten version of AngioTool, which features advanced analysis settings and batch processing.

AngioTool is a program designed to analyse eye scans for potential defects, using various algorithms to extract data from the scanned image. It was developed by the Center for Cancer Research from 2011-2014, and is commonly used in the ophthalmology field.

The intended use case was to view and analyse a scanned image, while also saving the results for record keeping and further analysis. However, in ophthalmology research, it is also used to process large collections of scans. Since AngioTool only lets the user analyse one scan at a time, this process becomes extremely tedious, especially when the scanning settings don't need to change.

This version of AngioTool lets the user select one or more folders, which are recursed fully such that every single non-output image inside those folders
