I use AI coding agents every day. I believe they are reshaping how we build software, and I think the teams that adopt them deliberately will outperform those that don't. I am not writing this to warn you away from AI-assisted development. I am writing this because the loudest voices in the AI enthusiasm camp are also the most allergic to discussing what can go wrong. And that worries me more than
On Second Thought — Episode 06 The ORM hides the SQL. The cache hides the ORM. The service mesh hides the services. The operator hides the YAML, which already hid the kubelet, which already hid the container, which already hid the process. By Tuesday, nobody quite remembers what the original problem was. They are too busy configuring its sixth wrapper. This is the post about that wrapper. When som
Every team experiences incidents. The teams that grow stronger from them are the ones that take postmortems seriously — not as blame sessions, but as structured learning opportunities. Yet most postmortems end up as a wall of text nobody reads twice, filed away and forgotten until the same incident happens again six months later. This guide walks you through writing postmortems that genuinely chan
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
