Old Computer Challenge
8 days ago
- The Old Computer Challenge (OCC) is an annual event where enthusiasts use old computers or minimal setups, starting in 2021 with a 7-day task on 512MB RAM.
- Solène Rapenne founded OCC, and the community gathers on IRC (#oldcomputerchallenge on libera.chat) and a mailing list (~tekk/old-computer-challenge@lists.sr.ht).
- In 2024, Tekk took over the website management after previous organizers stepped down, and the theme is DIY (Do It Yourself), encouraging participants to create something handmade during the event.
- OCC 2024 runs from July 5th to 12th, with no strict rules but a focus on creativity, such as writing stories, making music, or publishing programs.
- Past editions had specific themes: 2023 emphasized nostalgia with old, slow computers; 2022 limited internet usage to 1 hour per day to mimic RTC modem experiences; and 2021 was the first edition with positive participant feedback.

3 days ago
- The project involved creating a 3D-printed brain trophy from an MRI scan in 2021.
- The process included converting DICOM to a mesh, cleaning in Blender, printing halves on an SLA printer, casting silicone molds, pouring pewter, and assembling with epoxy.
- A custom base was made using a router and chamfer bits, with a 3D-printed plaque.
- Key learnings included medical file types, new manufacturing techniques, and achieving a polished final result.
Do Wavy Walls Use Fewer Bricks? I Tested It in Blender
a day ago
- Crinkle Crankle walls are curvy brick walls that originated in ancient Egypt but are now more common in England.
- Online sources often claim these wavy walls use fewer bricks and are stronger than straight walls, but details are sparse and contradictory.
- The author built procedural serpentine and straight walls in Blender's geometry nodes to test brick usage and strength.
- At 100 meters, the serpentine wall used 55% as many bricks as a typical straight wall, confirming the brick-saving myth.
- Lateral impact tests with heavy balls showed both wall types failed, but the serpentine wall suffered less damage, potentially lowering repair material costs.
