Worth Reading: The Russian Alternate Internet

Actually practical and not necessarily a problem. The Security Council of the Russian Federation, headed by Vladimir Putin, has ordered the “government to develop an independent internet infrastructure for BRICS nations, which would continue to work in the event of global internet malfunctions.” (RT, the Russian government-funded news service.) RT believes “this system would be used by countries of the BRICS bloc — Brazil, Russia, India, China and South Africa.” —Dave Burstein @ CircleID

New Seagate tech promises to double hard drive speeds

Unable to even come close to SSDs in terms of performance, hard disk makers have chosen to compete with capacity. A SSD over 1TB in size starts to become expensive, especially for consumers, so HDD makers Seagate and Western Digital have gone for massive capacity, introducing drives with up to 14TB of capacity.But now Seagate promises greater speed thanks to a new drive head technology. Dubbed the multi-actuator technology, it’s a simple idea that’s been around a while but wasn’t economically viable in the past due to higher component costs.Hard drive heads are connected to an arm called an actuator. This moves back and forth across the disk while the disk spins. Hard drives have multiple platters for storing data, and the actuator arms have drive heads on both sides of the platter, since data is written to both sides of the platter.To read this article in full, please click here

2017 Internet Intelligence Roundup

With 2017 drawing to a close, year-end lookbacks litter media and the blogosphere like so many leaves on the ground. (Or piles of snow, depending on where you are.) Many tend to focus on pop culture, product/movie/music releases, or professional sports. However, given the focus of Oracle Dyn’s Internet Intelligence team on monitoring and measuring the Internet, we’re going to take a look back at significant Internet “events” of the past year, and how they have impacted connectivity for Internet users around the world.

Hurricanes Harvey, Irma, and Maria Cause Internet Disruptions

In late August, and through September, an active Atlantic hurricane season spawned a number of destructive storms that wreaked havoc across the Caribbean, as well as Florida and Texas in the United States. On the Caribbean islands that were hardest hit by the storms, the resulting physical damage was immense, severely impacting last-mile Internet infrastructure across the whole country. This was also the case in Florida and Texas, though on a much more localized basis. On September 25, we looked at the impacts of these hurricanes on Internet connectivity in the affected areas, noting that while some “core” Internet components remained available during these storms thanks to Continue reading

Worth Reading: Asynchronous Decision Making

Asynchronous decision-making is a strategy that enables geographically and culturally distributed software teams to make decisions more efficiently. In this article, I’ll discuss some of the principles and tools that make this approach possible. Synchronous decision-making, in which participants interact with each other in real time, can be expensive for people who work on a Maker’s Schedule, and they are often impractical for remote teams. We’ve all seen how such meetings can devolve into inefficient time wasters that we all dread and avoid. —Bertrand Delacretaz @ Open Source
