Egerton MS 1995Previously on this blog: โThe Book of St Albans (1486)โ (2026-05-22), in which I made a table of terms of venery, a.k.a. company terms, e.g. โan exaltation of larks,โ as in the eponymous book by James Lipton. I mentioned that the Book of St Albans actually has โan exaltyng of larkis,โ and that itโs only in Egerton MS 1995 (circa 1450), according to Lipton, that we find โan exaltacyon of larkysโ proper. But I couldnโt find any digitized copy of Egerton MS 1995 to verify that claim.๐Arthur OโDwyerWednesday, July 15, 2026

Reduce LLVM Build Artifact Storage Costs by 50% with Content-Defined ChunkingReduce LLVM Build Artifact Storage Costs by 50% with Content-Defined Chunking One of the classic strategies to speed up a system is to avoid redundant work. Scalable build systems like Bazel and Buck2 heavily employ this strategy in various ways, with remote caching and content-addressable storage being two prominent examples. While remote caching prevents repeating redundant build actions, content-addressable storage (CAS) exists for the purpose of data deduplication. However, traditionally CAS operates at the granularity of a single file. When you modify a single byte in a file and store it in a CAS, the CAS stores a second, complete file. Deduplication at the file level is quite palatable for smaller files; a single build invocation typically contains many thousands of small files. Who cares if we store a couple more? However, as file sizes increase, the cost of storing yet another slightly modified version of a file becomes more expensive. Instead of tossing a couple extra kilobytes into storage, you might be storing a few more gigabytes . Now, consider where these large files come from. These large files are often outputs of build actions, and those build actions depend on many smaller inputs. As those many inputs churn, the outputs also churn. Suddenly the cost of touching a tiny little source file isnโt just the cost of uploading a new version of the source file to CASโitโs now also the cost of all the large outputs that are produced by the build. This dictates the growth rate of your CAS storage costs, which scales directly with the number of incoming builds. At AI-scale, these costs have become more important than ever before.๐EngFlow BlogTuesday, July 14, 2026

Irreducible loopsThe dominator tree lets us identify natural loops : a back edge T->H whose head H dominates its tail T defines a loop with the single entry H . This works only for reducible control flow graphs. Optimized machine code and decompiler output routinely contain irreducible loops, which have more than one entry and thus no dominating header, so the dominator-based method cannot see them.
