Groups oppose US plan to collect social media info from visitors

Civil liberties and tech advocacy groups have opposed a move by the Department of Homeland Security to collect social media information from certain categories of visitors to the U.S.“This program would invade individual privacy and imperil freedom of expression while being ineffective and prohibitively expensive to implement and maintain,” wrote organizations like the American Civil Liberties Union, Center for Democracy & Technology and Electronic Frontier Foundation in comments to the Department of Homeland Security on Monday.The provision allows for collection of information on their online presence from certain categories of visitors in their visa-waiver arrival/departure records (Form I-94W) and their online application for an Electronic System for Travel Authorization (ESTA).To read this article in full or to leave a comment, please click here

IBM’s blazing Power9 chip is coming, and here’s what you need to know

IBM's Power processors have a storied history; they were notably used in the Watson supercomputer that outsmarted humans in the game of Jeopardy in 2011. The latest chip in the family, called the Power9, is coming next year, and it stands out for its blazing speed and for technologies never seen in chips before.IBM is spilling Power9 details at the Hot Chips conference in Cupertino, California, this week. Here's some important information about the chip.Power9 servers will be smarter than the Jeopardy winner The sheer computing power in Power9 will make supercomputers virtually unbeatable in Jeopardy, unless a superhuman demonstrating exceptional intelligence comes along. The Power9 architecture has up to 24 cores and provides blazing throughput to speed up complex calculations.To read this article in full or to leave a comment, please click here

Alleged NSA hackers probably gave away a small fortune by leaking exploits

Anonymous hackers probably gave away hundreds of thousands of dollars in potential sales in the black market when they leaked valuable cyberweapons allegedly stolen from the U.S. National Security Agency.The hackers, known as the Shadow Brokers, posted a sample file of the cyberweapons earlier this month and at least some of them appear to be zero-day exploits, or attacks that rely on software defects that practically no one knew about.Before they were publicly leaked, each of these zero-day exploits could have sold for a great deal of money, according to security researchers. They’re designed to affect firewall and router products from Cisco, Juniper Networks and Fortinet, in addition to those from Chinese vendors.To read this article in full or to leave a comment, please click here

Republicans subpoena three tech companies over Clinton emails

Republicans in Congress have subpoenaed three technology companies that declined to hand over documents about former U.S. Secretary of State Hillary Clinton’s private email server.On Monday, Datto, SECNAP Network Security and Platte River Networks received subpoenas from U.S. Rep. Lamar Smith, a Texas Republican.Smith is demanding documents from the companies as two congressional committees from the House and Senate investigate the Democratic presidential nominee’s use of a private email server while she was secretary of state.All three companies either sold products used in Clinton’s email server or were hired to maintain it, Smith said in the subpoenas. For example, Datto provided an online backup system that eventually began storing Clinton’s emails off site.To read this article in full or to leave a comment, please click here

EFF condemns Windows 10 data collection

The Electronic Frontier Foundation (EFF) is lambasting Microsoft over Windows 10's telemetry technology, urging it to "come clean" with customers.In a piece posted last week to the EFF's blog, Amul Kalia, the San Francisco-based advocacy organization's intake coordinator, criticized Microsoft's practice of collecting large amounts of data from Windows 10 users."Windows 10 sends an unprecedented amount of usage data back to Microsoft, particularly if users opt in to 'personalize' the software using the OS assistant called Cortana," wrote Kalia, referring to the voice-controlled digital aide. "Microsoft should come clean with its user community. The company needs to acknowledge its missteps and offer real, meaningful opt-outs to the users who want them, preferably in a single unified screen."To read this article in full or to leave a comment, please click here

Despite billions spent on cybersecurity, companies aren’t truly safe from hacks

Last year, private sector companies globally spent more than $75 billion on security software to safeguard their systems and data.That number is expected to grow about 7% annually, according to Gartner and other analyst firms. It doesn’t include all the massive amounts spent on fraud prevention by banks, a number that is widely underreported and expected to reach into the billions annually.Has all that spending made private sector data and systems any safer? Is customer personal data any safer?MORE ON NETWORK WORLD: 6 simple tricks for protecting your passwords The general answer is no, according to many analysts, but that’s not necessarily because the latest software is considered ineffective.To read this article in full or to leave a comment, please click here

Worth Reading: Big data is making us more more boring

The world today is awash in data. In 2015, mankind produced as much information as was created in all previous years of human civilization. Every time we send a message, make a call, or complete a transaction, we leave digital traces. We are quickly approaching what Italian writer Italo Calvino presciently called the “memory of the world”: a full digital copy of our physical universe. —MarketWatch

Microsoft acquires intelligent scheduling startup Genee

Microsoft has acquired Genee, a startup that provided a virtual assistant for scheduling appointments. The deal, announced Tuesday, will bring the Genee team into the Microsoft fold and put them to work on bringing intelligence into Office 365. Genee's service let users loop in an artificial intelligence assistant that could interpret sentences like "set up lunch at some point this week" and turn them into calendar appointments. Acquiring Genee is part of Microsoft's ongoing crusade to build intelligent productivity software and services using AI. The company has focused on that area under the tenure of CEO Satya Nadella, with features like Office Delve, which finds documents shared within an organization that are relevant to a user, and Focused Inbox in Outlook, which filters unimportant email into a separate tab so it's not cluttering a user's experience. To read this article in full or to leave a comment, please click here

DC Fabric Segment Routing Use Case (4)

In the last post in this series, I discussed using SR labels to direct traffic from one flow onto, and from other flows off of, a particular path through a DC fabric. Throughout this series, though, I’ve been using node (or prefix) SIDs to direct the traffic. There is another kind of SID in SR that needs to be considered—the adj-sid. Let’s consider the same fabric used throughout this series—

So far, I’ve been describing the green marked path using the node or (loopback) prefix-sids: [A,F,G,D,E]. What’s interesting is I could describe the same path using adj-sids: [a->f,f->g,g->d,d->e], where the vector in each hop is described by a single entry on the SR stack. There is, in fact, no difference between the two ways of describing this path, as there is only one link between each pair of routers in the path. This means everything discussed in this series so far could be accomplished with either a set of adj SIDs ore a set of node (prefix) SIDs.

Given this, why are both types of SIDs defined? Assume we zoom in a little on the border leaf node in this topology, and find—

Assume—
