The Week in Internet News: Placing Money on AI

AI manages your money: Artificial Intelligence may eventually replace your financial advisor, Forbes suggests. AI can already spot financial trends really fast, but it may eventually compete with the personal touch of a human advisor, the story says. “Because artificial intelligence learns so much faster than humans, it is simply a matter of time before artificial intelligence can read human nuances and have an emotional intelligence quotient that exceeds those of most humans. When that happens, in the next few years, financial advisers will have a hard time competing based on personal relationships.”

Banning news: Russia has moved to ban what the government defines as fake news, joining several other countries headed in the same direction, the Boston Globe reports. A second law bans the publication of information showing disrespect to government bodies and officials. The fake news law allows fines of up to US$15,000.

Less fake, more news: Despite headlines about the spread of fake news during the 2016 U.S. elections, a majority of U.S. residents didn’t see fake news on social media, two recent studies suggest. On Twitter, fake news appeared on the feeds of just 1.1 percent of users, according to one study detailed in Continue reading

Is jumping ahead to Wi-Fi 6 the right move?

In five years, all you’re going to find is Wi-Fi 6, or what most wireless experts are still calling 802.11ax. But five years is a long time. If you’re considering an early move toward the most cutting-edge Wi-Fi technology on the market, there are some hurdles that you’ll have to overcome.To read this article in full, please click here(Insider Story)

Last Week on ipSpace.net (2019W4)

The crazy pace of webinar sessions continued last week. Howard Marks continued his deep dive into Hyper-Converged Infrastructure, this time focusing on go-to-market strategies, failure resiliency with replicas and local RAID, and the eternal debate (if you happen to be working for a certain $vendor) whether it’s better to run your HCI code in a VM and not in hypervisor kernel like your competitor does. He concluded with the description of what major players (VMware VSAN, Nutanix and HPE Simplivity) do.

On Thursday I started my Ansible 2.7 Updates saga, describing how network_cli plugin works, how they implemented generic CLI modules, how to use SSH keys or usernames and passwords for authentication (and how to make them secure), and how to execute commands on network devices (including an introduction into the gory details of parsing text outputs, JSON or XML).

The last thing I managed to cover was the cli_command module and how you can use it to execute any command on a network device… and then I ran out of time. We’ll continue with sample playbooks and network device configurations on February 12th.

The case for network-accelerated query processing

The case for network-accelerated query processing Lerner et al., CIDR’19

Datastores continue to advance on a number of fronts. Some of those that come to mind are adapting to faster networks (e.g. ‘FARM: Fast Remote Memory’) and persistent memory (see e.g. ‘Let’s talk about storage and recovery methods for non-volatile memory database systems’), deeply integrating approximate query processing (e.g. ‘ApproxHadoop: Bringing approximations to MapReduce frameworks’ and ‘BlinkDB’), embedding machine learning in the core of the system (e.g. ‘SageDB’), and offloading processing into the network (e.g KV-Direct) — one particular example of exploiting hardware accelerators. Today’s paper gives us an exciting look at the untapped potential for network-accelerated query processing. We’re going to need all that data structure synthesis and cost-model based exploration coupled with self-learning to unlock the potential that arises from all of these advances in tandem!

NetAccel uses programmable network devices to offload some query patterns for MPP databases into the switch.

Thus, for the first time, moving data through networking equipment can contributed to query execution. Our preliminary results show that we can improve response times on even the best Continue reading

A Discussion On Storage Overhead

Let’s talk about transmission overhead.

For various types of communications protocols, ranging from Ethernet to Fibre Channel to SATA to PCIe, there’s typically additional bits that are transmitted to help with error correction, error detection, and/or clock sync. These additional bits eat up some of the bandwidth, and is referred to generally as just “the overhead”.

For 1 Gigabit Ethernet and 8 Gigabit Fibre Channel as well as SATA I, II, and III, they use 8/10 overhead. Which means for every eight bits of data, an additional two bits are sent.

The difference is who pays for those extra bits. With Ethernet, Ethernet pays. With Fibre Channel and SATA, the user pays.

1 Gigabit Ethernet has a raw transmit rate of 1 gigabit per second. However, the actual transmission rate (baud, the rate at which raw 1s and 0s are transmitted) for Gigabit Ethernet is 1.25 gigabaud. This is to make up for the 8/10 overhead.

SATA and Fibre Channel, however, do not up the baud rate to accommodate for the 8/10 overhead. As such, even though 1,000 Gigabit / 8 bits per byte = 125 MB/s, Gigabit Fibre Channel only provides 100 MB/s. 25 MB/s is eaten up Continue reading

In India, Days Left to Comment on Rules That Could Impact Your Privacy

The public has until 31 January to comment on a draft set of rules in India that could result in big changes to online security and privacy.

The Indian government published the draft Information Technology [Intermediary Guidelines (Amendment) Rules] 2018, also known as the “Intermediary Rules” for public comment.

When it comes to the Internet, intermediaries are companies that mediate online communication and enable various forms of online expression.

The draft Intermediary Rules would change parts of the Information Technology Act, 2000 (the “IT Act”), which sets out the requirements intermediaries must meet to be shielded from liability for the activities of their users. The draft rules would also expand the requirements for all intermediaries, which are defined by the Indian government and include Internet service providers, cybercafés, online companies, social media platforms, and others. For example, all intermediaries would have to regularly notify users on content they shouldn’t share; make unlawful content traceable; and deploy automated tools to identify and disable unlawful information or content, among other new requirements.

Here’s some more background:

  • News reports are citing a number of concerns about the draft rules. Ours centers on their potential impact on the use of encryption.
  • Encryption is the process Continue reading

This Data Privacy Day Take Steps to Protect Your Data

As champions of an open, globally-secure, and trusted Internet, International Data Privacy Day is a big deal around these parts.

But making sure you’re able to share what you want, when you want, should be something the world stands for more than once a year. Every day should be Data Privacy Day.

These days, it feels all too common to hear stories about policy or law enforcement officials trying to create backdoors into technologies like encryption. These backdoors could put our online security at risk.

Just a little over one month ago, Business Insider reported that smart home devices dominated Christmas 2018 sales on Amazon, while the Alexa app, which enables people to control those smart devices, was the most downloaded on Google Play and the Apple App store on Christmas Day.

As the Internet becomes more and more a part of our everyday lives, each of us can take actions to ensure that privacy and security are a top priority.

Let’s come together on Data Privacy Day to celebrate the possibilities an open, globally connected, trusted, and secure Internet brings. Here are ways you can help make it happen where you live:

My Privacy Online: Championing Trust in the Era of IoT

Data Privacy Day is a little like celebrating the anniversary of your first date.

They are both a yearly occasion to reflect on the most important relationships in our life, the former with those who know the most about us, the latter with our significant other.

It’s also a reminder that relationships are built on trust – and how fragile that trust can be.

Privacy online relies on trust at its core. But as we become more reliant on connected devices and virtual assistants to handle our most intimate health, banking, and private information, we’re putting our trust into shaky hands.

Honesty is the foundation of trust and it’s just as important in our relationships with loved ones as those with data brokers. It’s crucial for data brokers to be honest with users about who, when, and how people have access to their personal data, especially as we transition into smarter homes and cities.

Let’s face it: there’s a huge market for the information we share online. Both U.S. and Canadian Internet companies are increasingly trying to collect our personal data – whether we know it or not.

It’s clear we want more control over our privacy, but each Continue reading
