The first article on this blog explained how it was built in 30 minutes with Claude Code. Naturally, a blog needs comments. Same constraints: no database, no external dependencies, no Disqus tracking visitors. Just PHP + JSON files. Built in one session with Claude Code — the interesting part wasn't the code, it was the security audit that followed. A comment system without a database seems trivia
When building applications with large language models (LLMs), one of the most overlooked costs is how structured data is represented. Most systems use JSON. And JSON is inefficient for LLM input. KODA (Knowledge-Oriented Data Abstraction) is a schema-first data format designed to reduce token usage when sending structured data to LLMs. It works by: Defining structure once (schema-first) Encoding v
As we have talked about before, the Internet relies on numerical addresses, IP addresses to route data from one device to another. IPv4 offers around 4.3 billion addresses, we have discussed that that is not enough. While there is IPv6, another solution to this issue is through Network Address Translation (NAT) NAT allows multiple devices on a private network to share a single public IP address. T
DHCP stands for Dynamic Host Configuration Protocol. Rather than manually assigning IP addresses to devices when they join the network, DHCP does this on its own. Once a new device connects to the network, the DHCP is responsible for assigning in network configuration parameters such as subnet mask, default gateway, DNS servers, and an IP address. This saves time and effort as you do not have some
Optimisation HLS pour DOMTOM Ce dépôt documente une approche orientée ingénierie réseau pour optimiser la distribution HLS (HTTP Live Streaming) dans les territoires DOMTOM. L’objectif est d’améliorer la stabilité de lecture, la latence effective et la robustesse face aux variations de gigue, tout en respectant les contraintes de décodage client, de parsing de manifestes, et de routage ISP. Pers
CKS Study Memo on Network Policies official document: https://kubernetes.io/docs/concepts/services-networking/network-policies/ You can control traffic between pods using the NetworkPolicy resource. In the sample manifest, the selectors are written like this. ingress: - from: - namespaceSelector: matchLabels: user: alice - podSelector: matchLabels:
Contournement du flux vidéo FAI DOMTOM — FAQ Développeur (réseau, protocoles, parsing) Point de vue : cette FAQ est rédigée du point de vue d’un ingénieur logiciel/réseau traitant la couche transport, le routage ISP, la signalisation de session et la reconstruction applicative (parsing, dé-multiplexage, adaptation de manifestes), spécifiquement dans des contextes DOM-TOM où les chemins d’achemi
