With all of this in mind, I thought improving the speed of my own version of a slow site would be a fun exercise. The code for the site is available on GitHub for reference. It’s inherently tied to everything we build and develop. In DevTools, the Network inspector helps us see what the first webpage is doing too.

This approach is limited by what requestors can observe externally… To expose partial failures, a detector needs to exercise specific code regions with carefully-chosen payloads. Developers can also explicitly annotate an operation as @vulnerable. Developers can provide their own validator functions if desired.

If a PostgreSQL user wants to change these values, they need to recompile the PostgreSQL from the source code. This can be changed later using the pg_checksums utility, but that will be a painful exercise on a big database. For example, the network port at which PostgreSQL listens cannot be changed at the individual database level.

Decommissioning Public102 was an exercise in the mundane, gradually transitioning tiny service after tiny service to new homes over the course of weeks, as the development schedule allowed. Unfortunately, the network operations had a cruel surprise for us. Once it's proven, you can remove the old one and decommission it.

Recent posts here covering the slow pace of WebKit development and ways the mobile browser market has evolved to disrespect user choice have sparked conversations with friends and colleagues. Also, allowing other web browser engines could put users at risk if developers abandon their apps or fail to address a security flaw quickly.

The idea that preventing browser innovation is pro-user is particularly risible, leading to entirely avoidable catch-22 scenarios for developers and users. Circa '07, those web apps were notably slower than native code could be. Contemporary debates about app stores start from premises that could use review.

According to Tim Kadlec : A performance budget is a clearly defined limit on one or more performance metrics that the team agrees not to exceed and that is used to guide design and development. We advocate that when you develop your performance budget, you focus on these user-centric milestones over technical milestones. Collaborate.

Traditionally one of the major costs when moving data in and out of memory (be it to persistent media or over the network) is serialisation. The Twizzler KVS (key-value store) is just 250 lines of C code, and uses one persistent object for the index structure, and a second one for the data. The FOT structure has some pros and cons. .

In addition to the default Docker namespaces (mount, network, UTS, IPC, and PID), we employ user namespaces for added layers of isolation. Let’s go back to that kernel code example earlier. This, in turn, allows processes to exercise certain privileges without having any privileges in the init user namespace. User Namespaces.
