Finally! A DNA Computer That Can Actually Be Reprogrammed
- Although this research is still exploratory, reprogrammable molecular algorithms could be used in the future to program DNA robots, which have already successfully delivered drugs to cancerous cells.
- As these DNA tiles link up during the assembly process, they form a circuit that implements the chosen molecular algorithm on the input bits provided by the seed.
- Indeed, if Doty, Winfree, and Woods have their way, the molecular programmers of tomorrow won’t even have to think about the underlying biomechanics of their programs, just like computer programmers today don’t need to understand the physics of transistors to write good software.
- But according to Petr Sulc, an assistant professor at Arizona State University’s Biodesign Institute who wasn’t involved in the research, the development of reprogrammable molecular algorithms for nanoscale assembly opens the door for a wide range of potential applications.
Data Center World: Why Open19 Designs Matter for Edge Computing
- On the opening day of this year's Data Center World in Phoenix, Yuval Bachar, LinkedIn's principal engineer of data center architecture, was on hand to explain why the social network's Open19 Project will be an important part of data centers' move to the edge.
- The Open19 specifications center around standardized equipment form factors, "cages," connectors, cables, power shelves, and network switches that LinkedIn has developed for use in its data centers.
- Bachar said the design will be especially important at edge locations, which are any places away from large centralized data centers where servers are placed in close proximity to connected devices in order to reduce latency.
- This can be anyplace from server closets in branch offices to computers controlling robotics on factory floors to the equipment telecoms place at cell tower locations to handle the data being generated from mobile traffic, and more.
Hyperscale Cloud Platforms Changed Data Center Design and Function. Here's How
- Informa PLC's registered office is 5 Howick Place, London SW1P 1WG.
- It was August 2014 when a team of Gartner analysts declared that original design manufacturers (ODMs) were having a greater influence on the implementation of data centers than traditional OEMs. This was on account of the growing purchasing power of hyperscale customers — organizations looking to build big, but also in modular segments that scale more rapidly to changing traffic demands.
- Yet as other data center design practitioners and experts tell us, just because hyperscale is associated with “big” doesn’t mean it’s necessarily a premium tier.
- It is a way of implementing resource scalability on a very large scale, and it has been championed by the largest consumers of those resources.
- Has hyperscale impacted the design and implementation of all data centers, everywhere in the enterprise, in the way that conventional wisdom anticipated?
Nvidia announces $99 AI computer for developers, makers, and researchers
- A new product from Nvidia announced today at GTC — a $99 AI computer called the Jetson Nano — should help speed that process.
- The Nano is the latest in Nvidia’s line of Jetson embedded computing boards, used to provide the brains for robots and other AI-powered devices.
- Plug one of these into your latest creation, and it’ll be able to handle tasks like object recognition and autonomous navigation without relying on cloud processing power.
- Past Jetson boards have been used to power a range of devices, from shelf-scanning robots made for Lowe’s to Skydio’s autonomous drones.
- The company also unveiled a fun DIY project for any advanced makers: an open-source $250 autonomous robotics kit named JetBot (above).
To Get to Six Data Centers Per Region, Facebook Rethinks Its Network (Again)
- It’s all this new hardware that’s generating a volume of in-region network traffic the three-data center fabric is having trouble keeping up with, Omar Baldonado, director of software engineering on Facebook’s network infrastructure team, said while speaking at the summit.
- The event where Facebook announced all this (an annual conference showcasing the latest data center technology developments within the Open Compute Project’s orbit) comes less than five years after the company launched in Iowa the first data center running its current-generation network fabric, which Baldonado described as “the classic Facebook fabric.” It’s been less than three years after Facebook revealed its current-generation network hardware designs (the Backpack fabric switch and the Wedge 100 top-of-rack switch) and just one year after it announced the Fabric Aggregator, the massive rack-size network switch used to shuffle traffic between data centers in a region.
