Articles on AI governance, cybersecurity and systems architecture.
The state of convolutional networks for skin-lesion classification in mid-2019: where the public benchmarks hold, and where integration into a laboratory workflow remains the open problem.
Read moreFHIR Release 4 (4.0.0, December 2018) is the first version with Normative content: the REST API, XML/JSON formats, base datatypes and a few clinical resources leave Trial Use with a backward-compatibility commitment. A technical note on the boundary of the Normative set and what changes for those building clinical systems.
Read moreThe Jetson Nano announced at GTC 2019 puts 128 Maxwell cores and CUDA 10 into a 99-dollar, 5-10 W device. The interesting part is the continuity of the stack between training on desktop GPUs and inference at the edge, not the price.
Read moreFalco reads the Linux kernel system-call stream and matches it against declarative rules to flag anomalous behaviour in running containers. Architecture, the new Kubernetes audit-event source in 0.13.0, and the limits of the model.
Read moreAt KubeCon Seattle (December 2018) Grafana Labs presented Loki, an alpha-stage log aggregator that indexes only the labels of each stream and keeps the compressed content on object storage. Notes on the Cortex-derived architecture and on the cost-versus-search trade-off.
Read morePodman manages containers with a fork-exec model rather than a persistent daemon. Technical notes on the architecture, on rootless via user namespaces, and on current limits, at version 0.12.
Read moreThe nnU-Net preprint (arXiv 1809.10486) argues that, for medical image segmentation, a well-configured standard U-Net beats architectural variants. Notes on the data fingerprint, the three configurations and the provisional Medical Segmentation Decathlon results.
Read moreRFC 8446 cuts the TLS handshake to a single round-trip, makes forward secrecy mandatory and takes legacy cryptography out of the standard. Reading notes on what it means in practice for people running servers.
Read moreBy 2018, models on clinical records and diagnostic images beat the published baselines, but the constraint that decides everything is the data: scarcity, quality, treatment regime, and GDPR.
Read moreFrom 25 May 2018 processing health data starts from a prohibition and ten exhaustive derogations. The Article 9(2) derogation you invoke decides who reads the data, where it may travel, and when a clinical dataset must stay separate from a research one.
Read moreNestJS, a Node.js framework in TypeScript with decorators, dependency injection and modules borrowed from Angular. What the 4.x line offers, and where the cost of the abstraction sits.
Read moreWith cert-manager the TLS certificate lifecycle becomes a declarative cluster resource. Project status, the CRD model, and the ACME constraints as of February 2018.
Read moreSigma is a YAML format for detection rules that a compiler translates into the search syntax of whichever SIEM is in use. Technical notes on the format, the sigmac converter, and where it breaks down.
Read moreOn 29 March 2017 the CNCF accepted containerd as an incubating project, while CRI-O matured in the Kubernetes incubator. Two answers to the Container Runtime Interface introduced in Kubernetes 1.5.
Read moreControlled clinical terminologies are not interchangeable: SNOMED CT describes the clinical picture, LOINC names observations and reports, ICD classifies for statistics and reimbursement. Boundaries, licensing and Italian adoption as of 2017.
Read moreGrafana neither collects nor stores metrics: it queries external sources through data source plugins and draws dashboards. Technical notes on a decoupled architecture and on the Apache 2.0 licence.
Read moreWhen a region's data comes from heterogeneous sources, integration is decided on the choice of protocols. A survey of REST, gRPC, GraphQL, MQTT and the OGC standards as of January 2017.
Read moreSleep stages are derived from physiological signals read according to codified rules. Scoring standards, data exchange formats, actigraphy and the EU regulatory path for sleep-analysis software as of early 2017.
Read moreAutomatic sleep staging between the historical actigraphy rules and time-series classifiers on polysomnographic signals, constrained by class imbalance and clinical validation.
Read moreA fab lab is defined by a shared inventory of machines and a common open-source toolchain. The opening of Fab Lab Toscana in Cascina is an occasion to examine what makes the nodes of the Fab network interoperable.
