The Morning Paper

DECEMBER 8, 2019

At the start of November I was privileged to attend HPTS (the High Performance Transaction Systems) conference in Asilomar. Byte-addressable non-volatile memory,) NVM will fundamentally change the way hardware interacts, the way operating systems are designed, and the way applications operate on data. PLOS’19.

sounds like a homework exercise of purely academic value. I've refuted many benchmarks by showing that they would require a network throughput that would far exceed the maximum network bandwidth (off by, for example, as much as 10x!). Networking is the easiest to check. This is really asking "what's the limiter?"

A resilient system continues to operate successfully in the presence of failures. There are many possible failure modes, and each exercises a different aspect of resilience. Hence, one way to reduce risk is to make systems more observable. This discussion focuses on hardware, software and operational failure modes.

All Things Distributed

NOVEMBER 15, 2010

Werner Vogels weblog on building scalable and robust distributed systems. Now that our ability to generate higher and higher clock rates has stalled and CPU architectural improvements have shifted focus towards multiple cores, we see that it is becoming harder to efficiently use these computer systems. All Things Distributed.

Does Apple restrict, in any way, the ability of competing web browsers to deploy their own web browsing engines when running on Apple's operating system? Some engines go further, adopting safer systems languages in their first lines of defence, or using a larger number of sandboxes to strictly isolate individual websites from each other.

New low-end devices are 4-to-8 core, 2GHz systems with 2GiB of RAM. Portable, safe apps returned massive benefits to users who no longer needed to LARP as systems administrators. Apple's defenders offer contradictory arguments: Browsers are essential to modern operating systems, and so iOS includes a good browser.

SQL Performance

The relational model and the standard querying language that is based on it are supposed to deal only with the conceptual aspects of the data and leave the physical implementation details like storage, optimization, access and processing of the data to the database platform (the implementation ). The application could end up with bugs.
