U.S. offers supercomputing help to manufacturers

Five of the top 12 high performance computing systems in the world are owned by U.S. national labs. But they are beyond reach, financially and technically, for many companies, even larger ones.That's according to U.S. Department of Energy (DOE) officials, who run the national labs. A new program aims to connect manufacturers with supercomputers and the expertise to use them.This program provides $3 million, initially, for 10 industry projects, the DOE announced Wednesday. Whether the program extends into future fiscal years may well depend on Congress.To read this article in full or to leave a comment, please click here

Dell to bring new hyperscale rack architecture to mid-range customers

Dell is bringing the advantages of its enterprise-level hyperscale rack servers to a wider range of customers.At Mobile World Congress next week, Dell will show off its new DSS 9000 hyperscale rack architecture, a server technology that allows computing and storage resources to be decoupled. The new rack design, aimed at mid-sized to large businesses, is based on Intel's Rack Scale Architecture, which is meant to bring configuration flexibility and power efficiency to Web-scale tasks.The DSS 9000 will ship in the second half this year, Dell said.The hyperscale architecture is already available to Dell's largest customers through the company's DCS (Data Center Solutions and Services) division. The architectural blueprint will be made available to mid-range hyperscale customers through the recently formed DSS (Datacenter Scaleable Solutions) group.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Researchers reach data rates 50,000 times faster than home Internet

Researchers from University College London claim to have reached a data rate of 1.125 terabits per second, the fastest data rate ever recorded between a single optical transmitter and a receiver, according to an article on the university's website.It's quick enough to download the entire high-definition Game of Thrones series in one second, the scientists claim.'Super-channels' A way of combining carriers into what the scientists call a "super-channel" is key to obtaining the speeds. Super-channels are used for sending bulk data between cities and continents, they explain.To read this article in full or to leave a comment, please click here

Apple’s fight with the FBI could go all the way to the US Supreme Court

Apple may have taken on the fight of its life in standing up to the FBI, which is demanding that it help break into an iPhone used by one of the perpetrators in December's San Bernardino mass shooting. Apple has promised to fight a U.S. magistrate judge's order Tuesday requiring it to assist the FBI, and legal experts say the case could go all the way up to the Supreme Court. Apple needs to tread carefully, however. A divisive presidential election has further polarized the country around issues including how to respond to terrorists, and Apple needs to be careful the public doesn't turn against it.To read this article in full or to leave a comment, please click here

Faux phishing scheme shows how hacks unfold

Many CIOs have implemented software that dupes employees into clicking on links and attachments that simulate phishing scams, an increasingly common educational tool to warn workers about the dangers of suspicious email messages. Security software maker Bitglass has reversed the shenanigans by leaking faked Google Apps credentials on the Dark Web, a hacker's playground for trafficking in stolen data. Then it tracked the activity, watching the many ways in which hackers wreaked havoc with supposed stolen online identities.

Yahoo heads in new research direction

The latest move in the topsy-turvy world of Yahoo is to ditch its Labs organization and squeeze its researchers into its product teams to help bring new ideas to market more quickly.Yahoo VP of Research Yoelle Maarek spun the development this way in a blog post this week: Recently we announced our efforts to make Yahoo a more focused company. This focus will let us accelerate the pace of innovation to make our products even better. We saw these changes as an opportunity to better align our research efforts, while preserving Yahoo’s culture of exploration and inquiry. As a result, we are reorganizing Yahoo Labs and moving forward with a new approach to research at Yahoo.To read this article in full or to leave a comment, please click here

Hard-coded password exposes up to 46,000 video surveillance DVRs to hacking

Up to 46,000 Internet-accessible digital video recorders (DVRs) that are used to monitor and record video streams from surveillance cameras in homes and businesses can easily be taken over by hackers.According to security researchers from vulnerability intelligence firm Risk Based Security (RBS), all the devices share the same basic vulnerability: They accept a hard-coded, unchangeable password for the highest-privileged user in their software -- the root account.Using hard-coded passwords and hidden support accounts was a common practice a decade ago, when security did not play a large role in product design and development. That mentality has changed in recent years and many vendors, including large networking and security appliance makers, are frequently issuing firmware updates to fix such basic flaws when they are discovered by internal and external security audits.To read this article in full or to leave a comment, please click here

Building nginx and Tarantool based services

Are you familiar with this architecture? A bunch of daemons are dancing between a web-server, cache and storage.

What are the cons of such architecture? While working with it we come across a number of questions: which language (-s) should we use? Which I/O framework to choose? How to synchronize cache and storage? Lots of infrastructure issues. And why should we solve the infrastructure issues when we need to solve a task? Sure, we can say that we like some X and Y technologies and treat these cons as ideological. But we can’t ignore the fact that the data is located some distance away from the code (see the picture above), which adds latency that could decrease RPS.

The main idea of this article is to describe an alternative, built on nginx as a web-server, load balancer and Tarantool as app server, cache, storage.

Improving cache and storage
