Microsoft announced on Tuesday that Microsoft Wallet users could make payment via NFC feature at stores.

Microsoft claimed the NFC feature will be introduced to Lumia 950, Lumia 950 XL and Lumia 650. This service is supported by over one million retail stores. The Microsoft Wallet is provided by Windows Insider Program. Besides the NFC feature, it could be used as deposit and membership card in order that the users could scan these cards and check on the cellphone.

Microsoft has not made great achievement in mobile payment field yet. Microsoft Wallet becomes a touch-less payment mode for enterprises so that users could make payment at the stores. Apple Pay was released in the second half of 2014 while Sample Pay was introduced by the end of 2015. The latter will be introduced to Spain, Singapore and Australia soon.

James Wester said digital Wallet becomes one of the necessary functions that consumers wish to have like camera, music player and GPS.

Juniper Research predicted that the mobile payment and wearable touch-less payment revenue will reach $95 billion in 2018.

Jordan Mckee, for whom works in 451 Research, claimed the mobile payment functions help to increase consumers’ loyalty. To Microsoft, the mobile payment function could strengthen the attraction of developers to Windows platform.

451 Research suggested that this NFC function won’t help a lot to Microsoft’s WP share. It did an investigation concerning the smartphone user shares in March, of which 10% users took the mobile payment function into consideration when they bought a new one. Only 1% of users considered purchasing Microsoft smartphone which was 2% decline compared with last December’s data.

Richard Crone, whose CEO of Crone Consulting, indicated if Microsoft acquires LinkedIn successfully, it has chance to use the NFC function to explore mobile P2P and other services.

It is reported that the giant video website YouTube is launching a new subscribed service called Unplugged which allows subscribers to watch video content and cable tv channels via internet.

To introduce this project, YouTube is said to have its technical instructure adjusted. The Unplugged service is the priority project that YouTube wants to promote. It will be released in 2017. Its senior managers are negotiating with other large-scale medie companies such as NBC universal, Viacom Inc, 21st Fox and CBS. It is unclear that whether this service will be authorized with tv show copyrights.

YouTube is working hard to introduce excellent subscribed service for video content. It released the YouTube Red service in last fall. Unplugged service will be able to introduce more high quality video content into YouTube network service and mobile applications so that YouTube could attract more users and make profit.

YouTube has been developing bundled network services since 2012. Christian Oestlien and Johanthan Zepp are mainly responsible for Unplugged project. Dish and Sony released the network tv service when Apple and Amazon were preparing to introduce the similar services.

YouTube did not make comments on this Unplugged service so far.

Sundar Pichai suggested the company aims to offer more options for its YouTube fans and interactions with creators. This plan started from YouTube Kids and YouTube Red.

YouTube also consider bundling up the unpopular tv channels to customize some shows. For example, YouTube Unplugged comedy channel might include 3 or 4 tv channels which are similar to Comedy Central.

If YouTube Unplugged works, it will bring more new audience for the company. What’s more, there will be more medium provide tv channels authorization to YouTube.

The audience rating of ESPN and TNT keep declining. The media companies hope to increase the audience rating via bundled network tv service.

Issues happen. It’s an unavoidable component of modeling complex systems and decisions. I had the chance to really think about this while taking cover in a bus shelter during a sudden Austin deluge.

While weather forecasts driven by advanced modeling systems are quite useful, a part of me knows to always hedge against their inherent unreliability.

In this sense it’s not surprising that most of the early success of machine learning in the enterprise has clustered around low-error-cost problems. Models for targeting ads, or recommending products, friends or connections, do not wreak havoc when they misfire. Most end users of the system are not attending closely to the advises.

And even if they do see an issue it’s trivial enough to be amusing, why was I recommended a meat grinder with my book of vegan recipes? The occasional success — an excellent suggestion that inspires someone to click — is far more important than frequent misfires.

But what about problems where an error is costly, such as supply chain optimization, trade planning and perioperative care? As we integrate data science and machine learning into the enterprise, better approaches to error mitigation are required to operationalize and scale analytics. Central to this effort is an acknowledgement of the distinct ways in which humans and machines err.

We must build analytic systems that effectively combine the domain knowledge, world knowledge and intuition of an organization’s people with the vast data context of its machines.

Classic decision support systems represent a version of this approach, and business intelligence tools are their modern instantiation. By summarizing and visualizing business data, BI software assists executives and decision makers in their reasoning by giving them an accurate view of the past. The difficult work of connecting an understanding of the past to action in the present is left as an exercise for the decision maker.

Thoughts on Computer Security

When it comes to the said term, Computer Security, here’re the things to include. Scroll for details.

Part One: Hardware Security

First and foremost, I highly recommend enabling an UPS device to your personal computer or your own computer network.

What’s an UPS device? Why?

UPS, Uninterruptible Power Supply, is also known as Uninterruptible Power Source. See? The name itself is quite easy to understand. It was created to mainly help avoid power surges. Such a power backup would be the one when your house, office even company runs into a sudden electrical problem, or simply, the electricity supply system is not steady due to some reason – this would also hurt the motherboard in your case.

How to choose a UPS?

It depends on situation. For a desktop PC, think about the following factors:

  • Your investment
  • Capacity. Choose one that meets your electricity needs. Example, you should take control of how many uses your computer, monitor, additional devices, and other components.
  • Output. Make sure the one you’re going to buy has enough outlets to protect your hardware.
  • Run Time. How long will the device run when your power becomes unavailable?
  • Monitoring. Need a fancy light only? Or, you need to manage a small local computer network? For the latter option, you had better gain a more efficient UPS management system equipped with relevant software and/or user interface, such as an administration URL/tool.

Then, you can give one of the following brands a try:

  • APC, such as Back-UPS 450VA Network 40 UPS (mode, BN4001)
  • CyberPower: 450VA Battery Back-Up System (SE450G)
  • Tripp Lite: SmartPro 1000 VA Tower Digital UPS (SMART1000LCD)
  • Monster: Core Power 350 3-Outlet Surge Protector (121886-00)

How to manage your UPS like a pro?

  • Remove some potentially unimportant device like printer in time
  • Add some limitation to stream videos, listen music and such
  • Always make your own computing equipment a high priority

Part Two: Data Security

Data security means protecting data, such as a database, sensitive information, from destructive forces and from the unwanted actions of unauthorized users.

Then, how to maintain your own ID security and e-security? Well my responses are very inspiring. The following proactive tips will help enhance your lines of defense when using the risky Internet:

  • Always keep your operating system and anti-malware / antivirus program up-to-date (up-to-minute) & live (* enable the real-time protection mode when working or downloading something from the Web). This will hugely decrease the risk of infecting zero-day attack.
  • Always go to official resources; and avoid, at least test a 3rd-party download even an unknown file or attachment before opening it. This helps avoid those bloated setup files. Or, you can consider installing a VMware Station only if your computer meets its system requirements.
  • Learn how to customize your computer system the proper way. Examples are, ridding of some unused even pre-installed apps, services and other sponsored programs, removing some unused even unauthorized items/installations from programs list and/or browser settings, and such.
