Worth Reading: Learning blockchains

A blockchain is a digital ledger of records that’s arranged in chunks of data called blocks. These blocks then link with one another through a cryptographic validation known as a hashing function. Linked together, these blocks form an unbroken chain — a blockchain.
The reason that this type of data structure is useful for things like cryptocurrencies is decentralization, meaning the records inside this chain aren’t stored in any single location, are accessible by everyone, and are immutable by any one party. —Free Code Camp

Avoid manually installing Windows 10 Creators Update

The Windows 10 Creators Update began rolling out on April 11, but impatient users could do their own upgrade as early as April 5 thanks to a utility called the Update Assistant, which downloaded it and installed the update for you.A lot of people jumped on this offer, and thanks to a few blow-ups, Microsoft has found some problems with the update and now advises users not to manually install the Creators Update and instead wait until it’s automatically offered for Windows Update.+ Also on Network World: 10 hidden features in the new Windows 10 Creators Update + The reason for all this rather late call for caution is that Microsoft wants to iron out any issues for specific hardware configurations. It started the rollout for newer devices that were less likely to have problems. To read this article in full or to leave a comment, please click here

How HP reclaimed the title of world’s top PC maker from Lenovo

In late 2015, HP was reborn as a PC maker following a split of its parent organization, Hewlett-Packard. At the time, HP was a lost cause, and its double-digit decline in PC shipments was a main reason for the split.The new HP then set out to reclaim its spot as the world's top PC maker from Lenovo, a title it lost in 2013. It reached the goal in the first quarter of 2017, during which its PC shipments grew by 13.1 percent year over year.A series of cool products and decisions to cut off low-margin products helped HP return to the top. Lenovo's struggles also played a part, but HP's strong performance in North America was a deciding factor, IDC said.To read this article in full or to leave a comment, please click here

Microsoft adds another layer to the Windows 10 patching onion

Microsoft yesterday added another update cycle to Windows 10's monthly patching, saying that the new collection of non-security-only fixes would give corporate customers the "increased flexibility" they had demanded.On Monday, Michael Niehaus, director of Windows 10 product marketing, announced the new monthly update, saying that the company would initially issue it only to customers running 1703, the upgrade also known as Creators Update, which launched earlier this month."We will routinely offer one (or sometimes more than one) additional update each month," Niehaus wrote in a post to a company blog. "These additional cumulative updates will contain only new non-security updates" [emphasis added].To read this article in full or to leave a comment, please click here

FCC chairman plans to ‘reverse the mistake’ of net neutrality

The U.S. Federal Communications Commission will vote on May 18 to kick off a proceeding to "reverse the mistake" of the agency's 2-year-old net neutrality rules, FCC Chairman Ajit Pai said.The rulemaking proceeding would be the first step toward repealing the regulations and reversing the agency's 2015 decision to classify broadband as a regulated, telecom-like service.Pai didn't provide a lot of detail about his proposal during a speech Wednesday, but during the rulemaking, the FCC will seek public comment on how best to move forward with new net neutrality rules or guidelines, he said. The FCC is scheduled to release the text of Pai's proposal on Thursday.To read this article in full or to leave a comment, please click here

Don’t Miss our Self-Healing Networks Session at the Red Hat Summit

One of my favorite technology catch phrases is “all technology fails”, but when thinking about the network that thought becomes a very scary one. Yes, while all technology does fail, you will always do your best to not have the network be one of those. The concept of healing networks from a conceptual standpoint (the will to want to detect an issue and fix it as soon as possible) is not a new one, as network monitoring is always at the front of any network engineer's mind. We are just fortunate in this day and age to be able to take advantage of newer tools that provide better solutions. Ansible to the rescue!

If you are attending the Red Hat Summit, please make sure not to miss the Discovery Zone session entitled “Self-Healing Networks with Ansible” on Thursday, May 4th at 10:15AM.

In this presentation we will cover topics, such as:

Why Capturing Metrics from Your Network is Important
Defining Failure States
Auto-Remediation versus Remediation (if remediation is the optimal course of action)
How Are The “Small" Guys Doing It?
Best Use Cases for Ansible Core and Ansible Tower
How Can Consulting Services help?

At the end of this session, Continue reading

Companion mobile app exposed Hyundai cars to potential hijacking

The mobile application that accompanies many Hyundai cars exposed sensitive information that could have allowed attackers to remotely locate, unlock, and start vehicles.The vulnerability was patched in the latest version of the mobile app released in March but was publicly disclosed on Tuesday. It is the latest in a string of flaws found over the past few years in the "smart" features added by vehicle manufacturers to their cars.The Hyundai issue was discovered by independent researchers William Hatzer and Arjun Kumar when analyzing the MyHyundai with Blue Link mobile app.Blue Link is a subscription-based technology that's available for many Hyundai car models released after 2012. It allows car owners to remotely locate their vehicles in case of theft, to remotely unlock them if they lose or misplace their keys, and even to remotely start or stop their engine when they're parked and locked.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Why are mainframes still in the enterprise data center?

In the recent past, I've had the opportunity to speak with representatives of Cobol-IT, Compuware, Heirloom Computing, TmaxSoft and a few others who have targeted enterprises still using mainframes.A few of them, such as Compuware, are focused on adding rapid application development and deployment (aka DevOps) to the mainframe, making the environment seem relevant today.+ Also on Network World: Why banks love mainframes + Most of the others, however, are focused on convincing enterprises that it is finally time for them to abandon the mainframe and move those workloads to industry-standard x86 systems running Windows or Linux or, perhaps, to midrange Unix systems.To read this article in full or to leave a comment, please click here

IDG Contributor Network: How open banking can drive competitive advantage

In the banking sector, the concept of “open” can seem contradictory. Banks traditionally have a “duty of care” to protect their assets rigorously, as required by regulators and customers. Yet today banks are faced with increasingly complex requirements.The blending of the financial and technology sectors has created a world in which banks protect our assets, but they are also asked to constantly innovate, create new customer channels or services, and maintain compliance across a changing regulatory landscape. To keep pace and remain competitive, banks must take another page from the technology world and embrace open architectures. + Also on Network World: Financial services firm adopts agile for digital development + APIs are a mainstay of today’s technology and start-up culture, and they are a primary mechanism for building open architectures and platforms. From Yahoo to Facebook, Google, Amazon and more, industry vanguards and emerging companies alike have allowed third parties to access and build upon their codes and platforms via APIs. While giving peers and, in some cases, competitors “access to the house” might seem counterintuitive, the results are remarkable—continuous, rapid innovation, continued product development, and an open ecosystem of knowledge sharing.To read this article in full Continue reading
