Technical articles and historical engineering writing on software and systems engineering, real-time data processing, artificial intelligence, speech and signal processing, digital forensics, cybersecurity and algorithms.
The Blog contains my technical articles on software and systems engineering, artificial intelligence, digital forensics, cybersecurity, and the history of technology.
A provider-independent C# design that writes DbDataReader results directly to JSON or XML using one-time schema compilation, typed getters, Utf8JsonWriter, and XmlWriter without materializing a second row graph.
Why a single-row update is unsafe in legacy Oracle tables whose uniqueness the database never enforced: separating business key from physical row identity, deterministic candidate selection, ROWID targeting, transaction boundaries, and ORM identity assumptions.
GLIBC_x.y not found is often an ABI-baseline problem: the build environment can make a binary require a newer userland than the target RHEL system provides.
Safe numeric conversion in Oracle requires an explicit input format, NLS policy, invalid-value behavior, and NULL semantics before aggregation begins.
Mapping the CSV header to model metadata once and streaming rows avoids repeating reflection work per record and allows large files to be converted without loading them entirely into memory.
A personal engineering perspective from someone who has worked with Delphi, examining how it moved from highly productive desktop RAD to a narrower position in modern open-source, web, mobile, Linux and server-side software ecosystems.
FAISS index selection is a recall, memory, build-time and data-movement decision as much as a latency decision.
A QR Code Model 2 encoder must construct the complete standard-compliant pipeline, from data mode and Reed-Solomon error correction to matrix placement and mask selection.
SentencePiece applies normalization before subword segmentation; in Turkish, vocabulary size and morphology directly affect token length and model cost.
Evolutionary computation iteratively transforms a population of candidate solutions through selection, crossover, and mutation, while the fitness function determines the direction of the search.
The numeric Soundex variant packs the first letter and three phonetic digits into one integer while retaining Turkish characters in the candidate-matching process.
Turkish deasciification restores ASCII-written characters by evaluating surrounding patterns rather than replacing letters in isolation; ambiguity is resolved through lexical and contextual rules.
