Safari 16.4 Is An Admission

Alex Russell

This lack of transparency is by design and provides Apple deniability while simultaneously setting low expectations, making them easier to exceed. as an (eventual) exercise of monopolistic power that held the web back for more than a decade? However, aside from the reading of tea leaves, there's no way to know if work is progressing.

Why I hate MPI (from a performance analysis perspective)

John McCalpin

According to Dr. Bandwidth, performance analysis has two recurring themes: How fast should this code (or “simple” variations on this code) run on this hardware? The user environment defines the mapping of MPI ranks to hardware resources (cores, sockets, nodes). The source code to the library may not be available.

COVID-19 Hazard Analysis using STPA

Adrian Cockcroft

There are many possible failure modes, and each exercises a different aspect of resilience. Another problem is that a design control, intended to mitigate a failure mode, may not work as intended. STPA is based on a functional control diagram of the system, and the safety constraints and requirements for each component in the design.

The Pursuit of Appiness

Alex Russell

Pre-publication gates were valuable when better answers weren't available, but commentators should update their priors to account for hardware and software progress of the past 13 years. Fast forward a decade, and both the software and hardware situations have changed dramatically. Don't like the consequences?

Failure Modes and Continuous Resilience

Adrian Cockcroft

There are many possible failure modes, and each exercises a different aspect of resilience. Another problem is that a design control, intended to mitigate a failure mode, may not work as intended. This discussion focuses on hardware, software and operational failure modes. Book: Engineering a Safer World by Nancy G.

The top 5 reasons to run your own database benchmarks

HammerDB

That is why we run a workload designed exactly for this purpose as it gives us a “benchmark” 2. Benchmarks are nothing like your real applications, and that’s actually good thing because unlike your application a good benchmark application like HammerDB has been designed to scale. Scalability.
