MC-Repack

What it does

MC-Repack optimizes Minecraft mods and resource packs for size and speed. Minify PNG, JSON, and TOML files, remove comments, and compress files more efficiently. Written in Rust, works with JAR and ZIP archives. Download via Cargo or GitHub Releases.

MC-Repack will help you improve your Minecraft mods! Use this tool to shrink down mod files and optimize loading speed.

A repacking tool for Minecraft mods to optimize size and loading speed of mods. MC-Repack was created with a simple thought in mind: How many Minecraft mods and resource packs come with unoptimized files? And I don't mean just pretty-printed JSON files. You will be surprised that in some cases a PNG file's metadata added by Photoshop is much larger than its content. One other important thing is that MC-Repack determines if a file really needs to be compressed. Most PNG files and smaller JSON files will usually be stored uncompressed. This kind of operation saves bytes if a "compressed" form is larger than original. Also, uncompressed data can be loaded faster. MC-Repack shows all errors…from szeweq.xyz

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

  BBC “In Our Time”, categorised by Dewey Decimal, heavy lifting by GPT▲688

  I'm a big fan of the BBC podcast In Our Time -- and (like most people) I've been playing with the OpenAI APIs. In Our Time has almost 1,000 episodes on everything from Cleopatra to the evolution of teeth to plasma physics, all still available, so it's my starting point to learn about most topics. But it's not well organised. So here are the episodes sorted by library code. It's fun to explore. Web scraping is usually pretty tedious, but I found that I could send the minimised HTML to GPT-3 and get (almost) perfect JSON back: the prompt includes the Typescript definition. At the same time I…
