Supercharge HDD Write Performance with Linux's dm-writecache

This article delves into Linux's dm-writecache kernel module, which leverages an NVMe SSD as a write-back cache for slower HDDs, dramatically improving random write performance. The author demonstrates a speed increase of tens of times through experiments comparing random write speeds with and without dm-writecache. The article also covers other caching methods and tools like bcache and ReadyBoost, detailing the configuration of dm-writecache using both LVM2 and the dmsetup utility for those without LVM2. Finally, it summarizes the significant performance gains achieved with dm-writecache and suggests using the remaining NVMe space to cache other slower drives.

The 15th-Century Google Maps? The Astonishing Piri Reis Map

In 1929, a German theologian stumbled upon a gazelle skin parchment map in Istanbul's Topkapi Palace – the Piri Reis map, created by a 14th-century Ottoman admiral. This map depicts the coastlines of South America and Africa with remarkable accuracy, even hinting at Antarctica, defying the technology of its time. Compiled from at least 20 sources, possibly including a map by Columbus, the Piri Reis map wasn't mere art; it utilized sophisticated portolan charting with compass roses and navigational lines, baffling modern scientists with its precision. It showcases the peak of medieval navigation and exemplifies the power of cultural exchange and human ingenuity.

Large language models are expensive to train and deploy for assisting with Excel formula authoring. This paper introduces FLAME, a transformer-based model trained exclusively on Excel formulas. With only 60 million parameters and a fraction of the training data used by larger models, FLAME achieves competitive or even superior performance on formula repair, completion, and retrieval tasks compared to models like Codex and CodeT5. This is attributed to its novel pre-training objectives and Excel-specific tokenizer.
