Cluster Management for Distributed Machine Learning at Scale

Over the last couple of decades, those looking for a cluster management platform faced no shortage of choices. However, large-scale clusters are being asked to operate in different ways, namely by chewing on large-scale deep learning workloads—and this requires a specialized approach to get high utilization, efficiency, and performance.

Nearly all of the cluster management tools from the high performance computing community are being bent in the machine learning direction, but for production deep learning shops, there appears to be a DIY tendency. This is not as complicated as it might sound, given the range of container-based open source tools, …

Netdev 2.1 conference report

I attended the Netdev 2.1 Conference in Montreal from April 6 to 8. Netdev is a community-driven conference mainly for Linux networking developers and developers whose applications rely on code in the Linux kernel networking subsystem. It focuses very tightly on Linux kernel networking and on how packets are handled through the Linux kernel as they pass between network interfaces and applications running in user space.

In this post, I write about the three-day conference and I offer some commentary on the talks and workshops I attended. I grouped my comments in categories based on my interpretation of each talk’s primary topic. The actual order in which these topics were presented is available in the Netdev 2.1 schedule. The slides from the talks, workshops, and keynotes are posted under each session on the Netdev web site. Videos of the talks are available on the netdevconf Youtube channel.

Keynotes

Each day at the Netdev conference featured a keynote by a prominent member of the Linux networking community. Two of the keynotes covered higher-level views of Linux in the network in the enterprise, cloud, and the Internet of things. The other keynote covered details of the new eXpress Data Path Continue reading

Appeals court won’t rehear a challenge to net neutrality rules

A U.S. appeals court has denied a request by broadband trade groups to rehear its decision last June to uphold the Federal Communications Commission's controversial 2015 net neutrality rules.The court's decision on Monday is a hollow victory for net neutrality supporters. Just last Wednesday, new FCC Chairman Ajit Pai announced plans to repeal the rules at the agency, without a court ordering him to do so.To read this article in full or to leave a comment, please click here

Microsoft’s enterprise phone strategy flops as revenue evaporates

Microsoft last week quietly acknowledged that a year-old plan to focus phone sales on the enterprise market is dead."We had no material Phone revenue this quarter," said Amy Hood, the company's CFO, during an earnings call with Wall Street on Thursday.In fact, phone revenue amounted to just $5 million for the three-month stretch, representing a massive decline of 99% from the same period of the prior year. Assuming each Windows smartphone brought $500 to Microsoft, that was a sluggish pace of just five phones sold per hour. Worldwide.It's not as if the demise of Microsoft's phone business was a surprise. The division, which was based on the 2014 acquisition of Nokia, has been in trouble with a capital "T" since 2015, when Microsoft wrote off $7.6 billion, nearly the full price it paid for the Finnish company's mobile phone assets and a collection of associated patents.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Data breaches: It’s still personal

In a blog post last September, I highlighted how data breaches for the first half of 2016 shifted from stolen credit card data and financial information to the theft of something much more personal—identities. Unsurprisingly, this trend continued throughout the remainder of the year.According to the recently released Breach Level Index, 1,792 data breaches led to almost 1.4 million data records being compromised worldwide, an increase of 86 percent compared to 2015. Once again, identity theft was the leading type of data breach last year, accounting for 59 percent of all data breaches. To read this article in full or to leave a comment, please click here

Summoning All Youth! Let the World Know What You Think About the Internet!

I'm Bruna Santos, a Brazillian tech policy nerd!

For the past three years I have worked as a legal advisor at the Presidency of Brazil, covering Human Rights and Internet Governance issues and taking part in interesting discussions on the Internet in Brazil in past years like the Marco Civil da Internet (Brazilian Civil Rights Framework for the Internet) and Data Protection bill draft. I am also an alumna of the Brazilian School of Internet Governance, a CGI.br fellow at the 9th Latin America and Caribbean Regional Preparatory Meeting for the Internet Governance Forum, an ICANN Fellow during ICANN58, and a very proud member of the Internet Society Special Interest Group Youth Observatory.

Microsoft to host Windows as a Service AMA chat

News aggregator and fan community Reddit frequently hosts an “Ask me Anything” (AMA) live discussion where people can ask questions of celebrities, technologists, politicians, and whatnot and get answers almost in real time. They can be informative and entertaining, or they can turn into unmitigated disasters.Microsoft is no doubt hoping for the former as it hosts its own AMA event to give its customers the chance to ask about the company’s plans for Windows as a Service (WaaS), its efforts to move Windows to a internet-dependent state of continuous development rather than going the old route of just providing fixes and an occasional service pack before the next major OS release.To read this article in full or to leave a comment, please click here

MIT’s WiGait uses wireless signals to step up detection of health issues

Professor Dina Katabi's endlessly inventive team at MIT's CSAIL outfit has now come up with what it says is an unobtrusive way to wirelessly detect possible health issues via changes in walking speed.The Computer Science and Artificial Intelligence Laboratory (CSAIL) claims its WiGait system is more accurate than wearables like FitBits and smartphone-based step trackers, and they outline the technology in a new paper titled "Extracting Gait Velocity and Stride Length from Surrounding Radio Signals" to be presented at the ACM Conference on Human Factors in Computing Systems. The researchers claim WiGait, a wall-mounted device described as being the size of a small painting, is 95% to 99% accurate at measuring walking speeds of multiple people and requires no wearable gear on its targets.To read this article in full or to leave a comment, please click here
