an exploration into using historic gold embroidery materials and knowledge to craft a programmable 8 bit computer. Solely built from a variety of metal threads, magnetic, glass and metal beads, and being inspired by traditional crafting routines and patterns, the piece questions the appearance of current digital and electronic technologies surrounding us, as well as our interaction with them. Technically, the piece consists of (textile) relays, similar to early computers before the invention of semiconductors. Visually, the gold materials, here used for their conductive properties, arranged into specific patterns to fulfil electronic functions, dominate the work. Traditionally purely decorative, their pattern here defines they function. They lay bare core digital routines usually hidden in black boxes. Users are invited to interact with the piece in programming the textile to compute for them.
some good real-world measurements from Germany. Ireland’s residential electricity costs are roughly comparable to the Netherlands I think in price/kWh
Coming to presto soon apparently….
Iceberg tracks individual data files in a table instead of directories. This allows writers to create data files in-place and only adds files to the table in an explicit commit. Table state is maintained in metadata files. All changes to table state create a new metadata file and replace the old metadata with an atomic operation. The table metadata file tracks the table schema, partitioning config, other properties, and snapshots of the table contents. The atomic transitions from one table metadata file to the next provide snapshot isolation. Readers use the latest table state (snapshot) that was current when they load the table metadata and are not affected by changes until they refresh and pick up a new metadata location.excellent — this will let me obsolete so much of our own code :)
