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. So the approach taken by the authors is to use intrinsic watchdogs – these run concurrently with the main program inside the same process.

The Chrome team explains that “we are being very mindful of our approach to setting the bar for what is considered good user experience and hope to land on something that is practically achievable by all developers.”. The badging program could very well have a similar effect. Source: Chromium.

In addition to the default Docker namespaces (mount, network, UTS, IPC, and PID), we employ user namespaces for added layers of isolation. Programs will usually start with capabilities, perform any activities that require those capabilities, and then “drop” them when the process no longer needs them.

The video is on [youtube] and the demo starts at [0:50] (the slides are [here] or as a [PDF]): I'm demonstrating a tool I developed to turn my laptop's wifi signal strength into audio (someone described this as a BPF [theremin].) If you wish to develop your own BPF observability tools, start with bpftrace and only use BCC when needed.

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. This is the level at which decisions on whether to use data_checksums need to be taken.

On the last morning of the conference Daniel Bittman presented some of the work being done in the context of the Twizzler OS project to explore new programming models for NVM. The starting point is a set of three asumptions for an NVM-based programming model: Compared to traditional persistent media, NVM is fast. What about security?

We believe that making these GPU resources available for everyone to use at low cost will drive new innovation in the application of highly parallel programming models. General Purpose GPU programming. But with the third generation interfaces, the true power of General Purpose GPU programming was unlocked. From CPU to GPU.

The idea that preventing browser innovation is pro-user is particularly risible, leading to entirely avoidable catch-22 scenarios for developers and users. Safety is within our budget, assuming platforms don't make exotic and dangerous APIs available all programs — more on that in a second. " Platforms, while plural, are not equal.

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.

It describes the labs environment, DSLabs , developed at the University of Washington to accompany a course in distributed systems. Hence the DSLabs framework integrates model checking into a holistic distributed systems development environment (based on Java as the implementation language – it would be neat to see a Rust version!).
