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.

What Are the Pros and Cons of Push API?

It could be the fastest & efficient way that informs the visitors and/or readers about the updates like newly published posts.

In the meantime, some bad guys would also try getting the most of such a marketing approach. Example, a starter would get annoyed with some undesired in-text based advertising. As for contextual advertising, this could be really harmful when you’re using a risky or heavily sponsored website. You too would suffer from those ad powered links if your computer has been infected with adware or some other riskware (aka, risky software). Some site even has the ability to record or track your online reading habits even extra info like computer IP! For more case studies, read this blog.

If you are still suffering from unwanted pop-up, possibly misleading alerts/ information on your desktop, you should regularly check out (* keep an eye on) the following settings in your own OS: "Home Page", "Programs list" under Control Panel, and Startup. Detect and remove any newly installed, undesired and/or unknown software in your system, perform a security check later on Safe Mode with Networking only when you have your virus scanner updated to its latest build.

Google is working on improving its Google Glass technology, while also engaged in the concept of a driver less delivery truck.

The company holds a myriad of patents, and was recently granted two U.S. patents, one for a more rugged and flexible version of its computerized eyewear, and another for an autonomous delivery truck. Google received a patent for a hinged display device for its Google Glass smart eyeglasses on Feb 9.

The hinged device would enable the display screen, which sits slight over and above the user’s right eye, to be flipped up and out of the way. The display also is being built to be more rugged.

A Google spokesperson would not comment on the patents.” We hold patents on a variety of ideas – some of those ideas later mature into real products or some don’t,” the spokesperson said in an email to Computerworld.” Prospective product announcements should not necessarily be inferred from our patents.”

While the patent doesn’t specify that the new Glass technology is meant for a version of the device that would focus on enterprise users, industry analysts say the technology would be perfect for a version of Glass aimed at business.

“It’s nice to see Google build a product that would be so well-suited for enterprises,” said Zeus Kerravala, an analyst with ZK Research. “Typically, they try and move consumer technology into businesses, but in this case it seems like they are thinking of the specific needs of enterprises — like better quality glass.”

Google gave the world its first look at Google Glass during its annual Google I/O developers conference in 2012. With a processor, memory and a display screen, users wearing the glasses could take photos and video, and then upload the data to social networks. They also could use the wearables to view news alerts or maps of a city they’re walking through.

While Glass received wide attention, the device was criticized over privacy issues. Google eventually pulled back the glasses for to redo their look and functionality. The new patent appears to offer a look at some of the work Google is doing on its computerized glasses.

“This looks slightly more substantial,” said Ezra Gottheil, an analyst with Technology Business Research. “I think the Glass project is more business-oriented than it was originally. A hinged display makes Glass more flexible, more fit for a variety of applications.”
