Microsoft fixes buggy browser in Patch Tuesday update

Internet Explorer, always heavily scrutinized by both security researchers and online attackers, has once again gotten the majority of patches in this month’s Microsoft’s Patch Tuesday round of monthly bug fixes.For June, Microsoft issued 8 bulletins, which collectively contain 45 patches. The bulletin for IE alone MS15-06 contains 24 patches, including 20 that cover critical flaws, meaning they should be applied as quickly as possible.Other bulletins cover faults in the Windows operating system, the Office suite, Windows Media Player, Active Directory, and the Exchange Server.To read this article in full or to leave a comment, please click here

Multipath TCP

The Transmission Control Protocol (TCP) is a core protocol of the Internet networking protocol suite. This protocol transforms the underlying unreliable datagram delivery service provided by the IP protocol into a reliable data stream protocol. This protocol was undoubtedly the single greatest transformative moment in the evolution of computer networks. The TCP protocol is now some 40 years old, but that doesn’t mean that it has been frozen over all these years.

Intel to invest $125 million in startups run by women, minorities

To encourage diversity in IT, Intel Capital has established a US$125 million investment program targeted at startups run by women and under-represented minorities.The investment program complements a separate $300 million Intel initiative announced in January whose goal is to bring more women and under-represented minorities into its workforce by 2020.Intel already chose four companies, all of which have diverse work forces, for the first round of investments, totaling $16.7 million. Intel Capital has a pipeline of companies it is looking to fund, said Intel’s CEO Brian Krzanich, during a webcast on Tuesday.Intel has talked about plans to change its capital investment program to make it more accessible for women and minorities.

iOS 9 could be a step toward saving the tablet market

Earlier this week, I laid out some ideas on what Apple needs to do inject new life into the fading tablet category. It seems that Apple was already on track with at least part of my message. "For many, the iPad is the primary computer," Apple's senior vice president of software engineering Craig Federighi noted at Apple's World Wide Developers Conference keynote yesterday.See also: 5 ways Apple should re-invent the iPad To help out those people, who I think represent the future of the tablet market, the company delivered on a couple of the things I asked for. As many observers expected, Apple announced split screen and picture-in-picture functionality in iOS 9, as well as a new software keyboard that can also work a trackpad. (Personally, the improvements in text selection and movement could be the biggest benefit to using the iPad for real work—I've always found that process frustratingly awkward and inexact.)To read this article in full or to leave a comment, please click here

6 headaches Apple is fixing in iOS 9

Apple’s iOS 9 has plenty of major features to look forward to, such as a more intelligent Siri, transit maps, and, and side-by-side iPad apps. Just as important, however, are the little things—the minor headaches of previous iOS versions that Apple is now getting around to alleviating.+ Read all the news from WWDC +To recap, here are six iPhone and iPad annoyances that will disappear in iOS 9:1. A less-confusing shift key Pop quiz: On the default iOS keyboard, are the letters uppercase when the shift key is gray, or white? Unless you bother to memorize, this issue has likely been a constant source of confusion since iOS 7. (The answer, by the way, is white.) As 9to5Mac notes, hitting shift in iOS 9 will toggle the letters on the keyboard between uppercase and lowercase, so there’s no ambiguity about what you’re about to type.To read this article in full or to leave a comment, please click here

Two years after Snowden leaks, US tech firms still feel the backlash

Two years after the first leaks by Edward Snowden about U.S. surveillance programs, the country’s tech companies are still worried about a backlash from other governments.Several foreign governments continue to push policies requiring that data generated in their countries be stored within their borders, said Yael Weinman, vice president of global privacy policy at the Information Technology Industry Council.“We’ve all heard the metaphor—data is the new oil,” Weinman said at the Techonomy Policy conference in Washington, D.C., Tuesday. “Barriers to cross-border data-flows make doing business today ... much more difficult.”The first surveillance leaks from Snowden, a former contractor with the U.S. National Security Agency, came out two years ago, and the impact of the surveillance programs was part of the backdrop for several debates at the conference.To read this article in full or to leave a comment, please click here

Network Documentation Series: Logical Diagram

In this article, I will do a walk-through of a logical network diagram. As I also said in the Physical Diagram article: I prefer to use the term “logical” instead of “L3″ because it is more easily understood by somebody unfamiliar with the OSI model. It also removes the assumption (made by many non-technical people) […]

BRKARC-3004 APIC-EM Controller Workflow and Use Cases

Presenter: Markus Harbek, CCIE, CCDE

 
Who knows what SDN stands for?

  • Still Don’t kNow
  • Still Does Nothing
  • Schnitzel Dinner Night


APIC – Application Policy Infrastructure Controller

  • Data center
  • n9000s
  • Focus on application network profile. SLA, Security, QOS, load balancing
  • Application intent

UCI – User Centric Infrastructure

APIC-EM – APIC Enterprise Module

  • Catalyst, ISR, N7k, n6k, n5k, WLAN
  • Focus on user, things, network profile, QoS, security, SLA, device
  • Application intent

Eventually, APIC and APIC-EM will have a common policy model so they can share policies across DC and enterprise. They will not integrate directly but will talk to a common policy orchestrator.

APIC-EM is really focussed on brownfield deployments because the assumption is that customers already have networks up and running hat APIC-EM needs to integrate into. APIC-EM won’t cconfigure OSPF and STP today, things like that, because they’re more than likely already running.

Imperative Control

  • Baggage handlers at an airport follow sequences of simple, basic instructions

Declarative control

  • ATC tells where to take off from but not how to fly the plane
  • ATC tells the “what”
  • Pilot figures out the “how” part
  • In the network, this would be like the admin wanting segmentation between tenants, controller decides which technology Continue reading

HP will pay $100 million to settle Autonomy-related lawsuit

The ongoing saga surrounding HP’s ill-fated Autonomy acquisition continued on Tuesday with the company’s announcement that it will pay $100 million in a settlement agreement with PGGM Vermogensbeheer B.V.Dutch PGGM Vermogensbeheer is the lead plaintiff in the securities class action arising from the impairment charge taken by HP following its acquisition of Autonomy.HP acquired the British software maker in 2011 for $11.7 billion. The following year, HP announced the $8.8 million impairment charge as a result of what it called “accounting improprieties, misrepresentations and disclosure failures” in Autonomy’s financial statements. HP shareholders filed suit that same year.To read this article in full or to leave a comment, please click here

Microsoft outlines Internet of Things plans for Windows 10

At the Computex show in Taipei last week, Microsoft outlined its plans for the Internet of Things (IoT) and how both Windows 10 and Azure will play a part in the strategy.The IoT news was just one of many announcements made as part of a bigger keynote by Nick Parker, corporate vice president of the OEM Division at Microsoft, who was joined by Tony Prophet, corporate vice president for Windows and Search Marketing, and Roanne Sones, general manager of Windows Engineering.Prophet discussed Microsoft's goal of having 1 billion devices running Windows 10 in the next two to three years. The first partner in that ambitious project is Toshiba, which will build "next-generation Windows- and Azure-powered IoT solutions."To read this article in full or to leave a comment, please click here
