APEX Compute: A Zero-Dependency C++20 Engine for Vectorized Matrix Multiplication

·2 views

APEX Compute is a C++20 engine built from scratch with no external dependencies, designed to run cache-tiled, explicitly vectorized matrix multiplication (GEMM) on both ARM and x86 processors. The project pairs its low-level SIMD kernels with an automated benchmarking tool, apex-bench, and a differential validation suite, apex-validate, to check results for correctness. It also offers an optional natural-language layer powered by Gemma 4, which converts a user's stated intent into a structured hardware run plan. The project's source code is available in its public repository.

Why iPhone photos are saved as HEIC files and how to convert them to JPG

Since iOS 11, iPhones have stored photos in the HEIC format by default, which preserves quality at about half the file size of JPG. Many Windows applications, upload forms and print services do not accept HEIC, which causes compatibility problems. Users can switch the camera to the Most Compatible setting to shoot JPGs going forward, though files will be larger. Existing photos can be converted using transfer settings, Mac Preview or Finder, Windows Paint with extensions, or Linux command-line tools such as heif-convert. The article's author also promotes a free browser-based converter that processes files locally without uploading them.

Caching Bank Directories Safely Across Multiple Payout Providers

Bank lists are strong caching candidates because they are requested often, can be large, and change infrequently. Caching them incorrectly is easy, especially when several payout providers each use their own bank codes, names, and supported institutions. The article recommends provider-scoped cache keys that include country and a version, and warns against merging directories by bank name in the transfer path. It also advises paginating fully, preserving provider-issued identifiers, and treating stale data as acceptable for browsing but not for account validation. Overall, reference data should be scoped by its source and separated from the data used for transaction validation.

Preventing Duplicate Push Notifications When Background Jobs Retry

Notification systems must account for task queues that typically offer at-least-once execution, since retries can cause customers to receive repeated messages. To stop two workers from sending the same campaign, the approach locks the campaign row and moves it to a sending status within a single database transaction, so only the worker that claims it proceeds. Targets are built from active, validated device tokens with duplicates removed, and each delivery is recorded under a deterministic key with a unique constraint before the push provider is called. Delivery records track pending, accepted, and failed outcomes, and campaign totals are derived from these rows rather than optimistic counts. The result is that each campaign-device pair is submitted at most once within the application's own retry model, though exactly-once delivery cannot be guaranteed across every external push platform.

KYC Should Be Modeled as an Auditable Evidence Workflow, Not a Simple Flag

A single is_verified field cannot capture a genuine KYC process, which typically involves personal details, identity documents, liveness checks, address proof, database and sanctions screening, and staff review. Each step should be tracked with its own status, so one rejected or resubmitted step does not erase evidence from completed ones. Overall approval should follow from required steps and policy rather than whichever provider responds last. Provider integrations should be handled through adapters that normalize outcomes and keep restricted raw responses, with media stored behind protected references and sensitive identifiers kept out of logs. Every review action should be recorded in an audit trail capturing actor, change, reason, and timestamp.
