Application performance monitoring (APM) is the practice of tracking key software application performance metrics using monitoring software and telemetry data. Practitioners use APM to ensure system availability, optimize service performance and response times, and improve user experiences. Application performance management.

Site performance is potentially the most important metric. The better the performance, the better chance that users stay on a page, read content, make purchases, or just about whatever they need to do. With all of this in mind, I thought improving the speed of my own version of a slow site would be a fun exercise. Lighthouse.

Assertions have been a foundational tool for writing understandable computer code since we could write computer code… far older than C’s assert() macro, they go back to at least John von Neumann and Herman Goldstine (1947) and Alan Turing (1949). Run-time errors should be reported using exceptions, error codes, or similar.

With only an hour or so of degraded performance in the end, it’s not the worst incident you can imagine, but it was clearly taken as very serious given the time of year.

Decades of poor architecture guidelines and lax developer discipline resulted in the commercial-off-the-shelf components of an ERP becoming inseparable from the custom code built around it. A basic premise is that there are alternatives to traditional "lift and shift" strategies by retiring legacy assets in a piecemeal fashion.

Enabling students to build running performant versions of all of those systems in the time available is one challenge. We would like students to consider the performance characteristics of their systems, and our tests check that their designs attain reasonable run-time performance. Consider the lab exercise to implement Paxos.

Management textbooks dating at least as far back as the 1980s included stories of employees performing tasks the reasons for which they didn't really understand. There aren't a lot of high cards we can draw, but playing them in the right combination offers us a strategy. This month, we look at our options for re-acquiring it.

Otherwise, you’ll either get the implicitly generated move functions, or else requests to move will automatically just do a copy instead, since copy is always a valid implementation of move (it just doesn’t exercise the non- const option).

The new version of the application is deployed in the green environment and tested for functionality and performance. Both use the same database back-end and app configuration.
