SIMD Within a Register: How I Doubled Hash Table Lookup Performance

news.ycombinator.com Aleksey Maltsev 2025-12-30 14:41:34

While working on a Cuckoo Filter implementation in C#, I created an array-like structure for the underlying hash table. I chose an 8-bit fingerprint: it aligns nicely on a byte boundary and still keeps the false-positive rate around 3 %. The layout looked straightforward—just a byte array where the start of each bucket is calculated as bucketIdx * bucketSize . The size of each bucket is 4 slots, which is a solid choice for Cuckoo Filter. Bucket 0 3A 00 B7 F2 Bucket 1 4C 91 00 DE Bucket n AA 00

Wuchang: Fallen Feathers isn't a revolutionary Soulslike title that aims to change the subgenre, but it's catching the attention of many players right now, in part because it's available on day 1 on Xbox Game Pass. Wuchang, however, does have some issues with underexplaining certain mechanics, which is giving players a little trouble. Wuchang makes some changes to the Soulslike formula established by FromSoftware, the developers of Demon's Souls and Dark Souls. Those changes aren't laid out so

Chemical process produces critical battery metals with no waste

Olivine is a rather unassuming rock. Olive brown to yellow green in color, this hard yet brittle mineral is thought to be the most abundant in Earth’s upper mantle. Chemically, olivine is magnesium iron silicate, though it contains other elements too. Economically, it’s close to worthless. Its limited industrial utility stretches to gemstones, metalworking, ceramics, and occasionally, as a gravel for road construction. At some mining sites, olivine is a waste product, stored in piles on the surf

Breaking the WASM/JS communication performance barrier

news.ycombinator.com Unknown 2025-12-26 04:11:31

In sledgehammer every operation is encoded as a sequence of bytes packed into an array. Every operation takes 1 byte plus whatever data is required for it. Each operation is encoded in a batch of four as a u32. Getting a number from an array buffer has a high constant cost, but getting a u32 instead of a u8 is not more expensive. Sledgehammer bindgen reads the u32 and then splits it into the 4 individual bytes. It will shuffle and pack the bytes into as few buckets as possible and try to inline

OnePlus Nord 5 review: selfie-centric midranger

The OnePlus Nord 5 does exactly what the company’s Nord phones have always done: deliver strong specs at a relatively low price. It’s one of the more powerful phones at this price point and should easily outstrip Samsung and Google’s more expensive alternatives. This is a function-over-form phone, one where the key selling points are a powerful processor and long battery life, which are the boring mainstays that tend to matter the most in midrange models like this.
