In this video I explain End to End encryption within the context of WhatsApp. I explain how encryption and TLS works then the problem of having a centerlized server decrypting the traffic, I then talk about how end to end encryption (e2e) can help mitgate that and finally I explain the problems with e2e encryption Classic Encryption Example 1:00 End to end encryption 3:25 Problem with E2E 7:30 - Trust? Fingerprints/CA (QR whatspp) encryption 00:30 encryption, e2e encryption, end to end encryption, whatsapp end to end encryption, how e2e works, e2e limitations --- Support this podcast: https://anchor.fm/hnasr/support

Firefox has disabled TLS 1.0 and TLS 1.1 to improve your website connections. Sites that don't support TLS version 1.2 will now show an error page.  We reverted the change for an undetermined amount of time to better enable access to critical government sites sharing COVID19 information. https://www.youtube.com/watch?v=grVVuGnN9IE https://www.mozilla.org/en-US/firefox/74.0/releasenotes/ https://twitter.com/cramforce/status/1242515799215988737?s=21 --- Support this podcast: https://anchor.fm/hnasr/support

A sidecar proxy is an application design pattern which abstracts certain networking features, such as inter-service communications, monitoring and security, timeouts, retries, communication protocols, away from the main architecture to ease the maintenance of the application as a whole. In this video I’d like to talk about how we classically do things: Library Pattern getComments HTTP1:1/JSON Add features retries/timeout /hardcode the server name what it changed/add new server to load balance between them/credentials Sidecar pattern getComments HTTP/2 Sidecar proxy/container Examples Microservices (Linkerd, Envoy, Istio) Pros Language agnostic (polyglot) Protocol upgrade Security Tracing and Monitoring Service Discovery Caching Cons Complexity Latency SideCar Proxy must be layer 7 Library 2:25 Sidecar: 7:40 Example: 13:00 (https://www.youtube.com/watch?v=cp3Ku1XeOn8) Pros & Cons : 16:15 Cards 6:22 HTTP/2 10;50 Reverse Proxy / proxy ex

MySQL 8.0 supports atomic Data Definition Language (DDL) statements. This feature is referred to as atomic DDL. An atomic DDL statement combines the data dictionary updates, storage engine operations, and binary log writes associated with a DDL operation into a single, atomic transaction. The transaction is either committed, with applicable changes persisted to the data dictionary, storage engine, and binary log, or is rolled back, even if the server halts during the operation. I discuss mySQL 8.0 atomic ddl compared to Postgres transactional ddl --- Support this podcast: https://anchor.fm/hnasr/support

gRPC (gRPC Remote Procedure Calls[1]) is an open source remote procedure call (RPC) system initially developed at Google in 2015[2]. It uses HTTP/2 for transport, Protocol Buffers as the message format. In this video I want to explore gRPC, go through examples, pros and cons of gRPC. Client/ Server communication SOAP HTTP (REST) WebSockets Client Libraries gRPC gRPC Demo todos gRPC Pros and Cons Pros Fast two/uni and request Unform One library to rule them all Progress feedback( long synchronous requests) drop pluggable wait...) cancel request All benefits of H2 and Protobuff Cons schema based (not everyone wants schema) Thick client - limited languages - Proxies still don’t understand it Still young Error handling No native browser support Timeouts, circuit breaker just like any RPC (pub/sub rules in this case) Can you create your own protocol?
