Memory leaks in JavaScript don't announce themselves with an error. They show up as a heap that grows by 20MB per minute — invisible in a five-minute Lighthouse run, fatal in a six-hour production session. Why React apps leak: A useEffect that opens a WebSocket and never closes it on unmount. A setInterval without clearInterval in the cleanup return. A global Map that grows without bound. In each
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
Random 30–50ms freezes with no obvious long tasks in the Performance panel often have one root cause: the garbage collector. V8 pauses JavaScript execution to reclaim memory, and if your allocation rate is high enough, those pauses happen frequently — creating jank that shows up as a sawtooth pattern in the memory timeline rather than a spike in the flame chart. What this covers: How V8's generati
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.

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
