We’ve got our eyes on you: Ring, the Amazon-owned, IoT-powered video doorbell and security system vendor, has partnered with 400 police departments across the U.S. and is providing them with video footage, the Washington Post reports. Privacy advocates have raised concerns, saying the partnerships could subject innocent people, including those who Ring users have flagged as “suspicious,” to greater surveillance.
We’re listening, too: Meanwhile, Apple has apologized for some of its contractors listening in to recordings of customer’s interactions with the Siri digital assistant, Fox Business News says. Apple had been using the recordings for quality control, but the practice was not in line with Apple’s “high ideals,” the company said.
Also, the apps: Google has pulled a popular file-scanning app, CamSpanner, from the Google Play store, after reports that it contains malware, CNN reports. Researchers Kaspersky had found several negative reviews on the app’s profile that complained the app had the “presence of unwanted features.” The malware could show “intrusive advertising” to users.

What is Optimal Routing and Suboptimal Routing in Networking? This may be seen very easy for some of you but let’s make a philosophy a little bit, means let’s design around optimal routing. Network engineers know that one of the tradeoff in network design is Optimal Routing. We want our application traffic to follow Optimal …

SLOG: serializable, low-latency, geo-replicated transactions Ren et al., VLDB’19
SLOG is another research system motivated by the needs of the application developer (aka, user!). Building correct applications is much easier when the system provides strict serializability guarantees.
Strict serializability reduces application code complexity and bugs, since it behaves like a system that is running on a single machine processing transactions sequentially.
The challenge with strict serializability (or even just serializability on a regular DBMS) is that it requires coordination, and as we know, coordination kills performance. Weaker consistency models can give better performance yet “expose applications to potential race condition bugs, and typically require skilled application programmers.” But developers are the kingmakers (I think it’s been enough time now that we can drop the ‘new’ in that phrase?? ;) ), and thus:
… the demand for systems that support strict serializability has only increased.
So starting with strict serializability as a given, how do we claw back some of that performance? That’s where SLOG (Serializable LOw-latency, Geo-replicated transactions) comes in.
SLOG achieves high throughput, strictly serializable ACID transactions at geo-replicated scale for all transactions submitted across the world, all the while achieving low latency for transactions Continue reading
