Businesses need better automation to regain control of their data centers

The cloud continues to grow in popularity as businesses look to take advantage of digital trends. However, the term “cloud” is multi-definitional and means different things to different types of organizations. In the small-business segment, cloud likely means software as a service (SaaS), as those organizations want turnkey applications offered on a pay-as-you-go model. For larger companies, cloud means public infrastructure as a service, such as Amazon Web Services or Microsoft Azure.  [ Related: How to plan a software-defined data-center network ] Private clouds are alive and kicking For large businesses, the cloud likely means hybrid where private data centers make up most or even all of the cloud infrastructure. The ZK Research 2018 Global Cloud Forecast projected that by 2020, there would be more workloads in private clouds than in public clouds or available as legacy on-premises workloads.

Nvidia’s Datacenter Growth Beats Moore’s Law Big Time

Moore’s Law is effectively boosting compute capability by a factor of ten over a five year span, as Nvidia co-founder and chief executive officer Jensen Huang reminded Wall Street this week when talking about the graphics chip maker’s second quarter of fiscal 2019 financial results. …

[Sponsored] Short Take – Forward Networks

In this sponsored Network Collective Short Take, Brandon Heller, Co-Founder and CTO of Forward Networks, joins Network Collective to talk about how network verification and modeling are empowering network operators to increase efficiency, reduce mistakes, and shorten the mean-time-to-resolution when troubleshooting network issues.

Forward Networks does this through a complete and accurate mathematical model of the way your network operates, allowing you to quickly assess traffic flows and operational issues in your network without needing to query multiple devices manually.

Having an accurate model of your network also empowers you to validate changes before ever touching your production environment, giving you confidence that the change you are implementing will achieve the desired outcome.

For more technical details, short demo videos, and a chance to try Forward on your network to gain greater insight, head on over to http://forwardnetworks.com/collective.

Safe Online, Safe On Land: Promoting Safe Internet Use to Children in Kenya

On February 16th this year, MediaNet Works and the Internet Society Kenya Chapter launched “Safe Online, Safe On Land” a 12-month project that seeks to promote safe Internet usage and practices among children in Kenya. With funding from the Internet Society’s Beyond the Net Grants Program the project anticipates to reach 700 children, targeting Koinonia Community, four children’s homes, one secondary school, and three other schools in Ngong, Kajiado County.

In addition, 12 teachers, 15 child protection and social workers, 10 journalists from both the community and mainstream media, including the Bloggers Association of Kenya (BAKE), will benefit from this project.

Justification of the Project

The launch of this project coincided with media coverage of Internet and social media safety issues in the country. Cases of online child abuse and human trafficking have recently featured in local media. Consequently, the National Assembly on 26 April, 2018, passed the Computer Misuse and Cybercrimes Bill which is set to be presented to the president for assent. The Bill’s offenses relevant to this project include publication of fake news, pornography, cyberterrorism, cybersquatting, and child pornography.

To set the ball rolling consultative meetings between representatives of MediaNet Works and Koinonia Community were held Continue reading

The Cargo Cult of Google Tools

You should definitely watch this amazing video from Ben Sigelman of LightStep that was recorded at Cloud Field Day 4. The good stuff comes right up front.

In less than five minutes, he takes apart crazy notions that we have in the world today. I like the observation that you can’t build a system more than three or four orders of magnitude. Yes, you really shouldn’t be using Hadoop for simple things. And Machine Learning is not a magic wand that fixes every problem.

However, my favorite thing was the quick mention of how emulating Google for the sake of using their tools for every solution is folly. Ben should know, because he is an ex-Googler. I think I can sum up this entire discussion in less than a minute of his talk here:

Google’s solutions were built for scale that basically doesn’t exist outside of a maybe a handful of companies with a trillion dollar valuation. It’s foolish to assume that their solutions are better. They’re just more scalable. But they are actually very feature-poor. There’s a tradeoff there. We should not be imitating what Google did without thinking about why they did it. Sometimes the “whys” will apply Continue reading

What is Nmap? Why you need this network mapper

Network administrators, IT managers and security professionals face a never-ending battle, constantly checking on what exactly is running on their networks and the vulnerabilities that lurk within. While there is a wealth of monitoring utilities available for network mapping and security auditing, nothing beats Nmap's combination of versatility and usability, making it the widely acknowledged de facto standard.What is Nmap? Nmap, short for Network Mapper, is a free, open-source tool for vulnerability scanning and network discovery. Network administrators use Nmap to identify what devices are running on their systems, discovering hosts that are available and the services they offer, finding open ports and detecting security risks.To read this article in full, please click here

Fairness without demographics in repeated loss minimization

Fairness without demographics in repeated loss minimization Hashimoto et al., ICML’18

When we train machine learning models and optimise for average loss it is possible to obtain systems with very high overall accuracy, but which perform poorly on under-represented subsets of the input space. For example, a speech recognition system that performs poorly with minority accents.

We refer to this phenomenon of high overall accuracy but low minority accuracy as a representation disparity… This representation disparity forms our definition of unfairness, and has been observed in face recognition, language identification, dependency parsing, part-of-speech tagging, academic recommender systems, and automatic video captioning.

For systems that are continually trained and evolved based on data collected from their users, the poor performance for a minority group can set in place a vicious cycle in which members of such a group use the system less (because it doesn’t work as well for them), causing them to provide less data and hence to be further under-represented in the training set…

… this problem of disparity amplification is a possibility in any machine learning system that is retrained on user data.

An interesting twist in the problem is that the authors assume neither the Continue reading
