5 tips to help developers keep up with changing technologies

"One thing you realize early on," says Luke Tillman, technical evangelist for Apache Cassandra at DataStax, "is that things are constantly changing."That's a fact of life for developers and their managers. It's true whether you're working with JavaScript front-end frameworks or databases."You almost feel bad for front-end developers," Tillman says. "A front-end framework gets hot for a year or two and then you've got to change."So first, Tillman says, you've got to accept that change is constant. That's the easy part.Finding their motivation (Hint: it may be $$$) "Once you accept that change is constant, the question is not only how do you stay relevant, but also what is your motivation for staying relevant," Tillman says.To read this article in full or to leave a comment, please click here

New supercomputer will unite x86, Power9 and ARM chips

For once, there will be a ceasefire in the war between major chip architectures x86, ARM and Power9, which will all be used in a supercomputer being built in Barcelona.The MareNostrum 4 is being built by the Barcelona Supercomputing Center, and will have three clusters, each of which will house Intel x86, ARM and Power9 chips. Those clusters will be linked to form a supercomputer that will deliver up to 13.7 petaflops of performance.All three architectures have never been implemented together in a supercomputer, let alone PCs or servers. It raises questions on how the architectures will interoperate.The three chip architectures are fundamentally different. An application written to take advantage of a specific architecture won't work on another, but server architectures are changing so different types of systems can coexist. Linux supports x86, ARM and Power, so it's possible to write applications to work across architectures.To read this article in full or to leave a comment, please click here

Worth Reading: When will SD-WAN be Adopted?

The survey respondents were given a wide range of options and asked to indicate which options described their company’s approach to implementing an SD-WAN. Their responses, which are shown in Figure 1, show that there is broad interest in SD-WANs. For example, only a quarter of the respondents (26%) work for companies that have not yet made any analysis of SD-WANs and only a tenth of the respondents work for companies that have looked at SD-WANs but decided to not take any additional steps over the next year. However, that broad interest has not yet translated into broad adoption as only 5% of the survey respondents indicated that they currently have SD-WAN functionality running in their production networks. —ECI

IDG Contributor Network: The return of the infrastructure engineer

Corporate digital strategy—whether it involves the cloud, the Internet of Things or other technologies—has presented new opportunities for infrastructure engineering. The infrastructure engineer, traditionally relegated to hardware provisioning and maintenance, is now an integral part of solution design and delivery. But this shift entails new expectations along with new demand.The shift towards cloud-based, software-defined infrastructure requires today’s infrastructure engineer to marry traditional, specialized depth in a technology tower (e.g., network) with architectural breadth across towers. That doesn’t mean a network engineer needs equivalent expertise in storage and hosting technologies, but it does mean engineers have to understand how network, storage and hosting technologies (as well as software) interact and integrate to deliver a business outcome. As more core engineering activities in each tower become automated, engineers will become more focused on the configuration and orchestration of technologies to deliver seamless service performance.To read this article in full or to leave a comment, please click here

Is web-scale networking secure? This infographic breaks it down.

At Cumulus Networks, we take a lot of pride in the fact that web-scale networking using Cumulus Linux can have an immense impact on an organization’s ability to scale, automate and even reduce costs. However, we know that efficiency and growth are not the only things our customers care about.

In fact, many of our customers are interested first and foremost in the security of web-scale networking with Cumulus Linux. Many conclude that a web-scale, open environment can be even more secure than a closed proprietary one. Keep reading to learn more or scroll to the bottom to check out our infographic “The network security debate: Web-scale vs. traditional networking”

Here are some of the ways web-scale networking with Cumulus Linux keeps your data center switches secure:

  • Cumulus Linux uses the same standard secure protocols and procedures as a proprietary vendor: For example, Openssh is used by both traditional closed vendors and Cumulus Linux. The standardized MD5 is used for router authentication, and Cumulus supports management VRF.
  • Web-scale networking has more “eyes” on the code with community support: Linux has a large community of developers from different backgrounds and interests supporting the integrity of the code. Since an entire community of Continue reading

IDC predicts the collapse of the Windows Phone by 2020

Microsoft’s mobile OS is tracking to eventually drop to 0.1 percent market share, and the proposed Surface Phone line expected next year won't do anything to stop that decline. That's the conclusion from IDC, which just released its latest Worldwide Quarterly Mobile Phone Tracker. It puts global smartphone year-over-year growth in 2016 at a paltry 0.6 percent That's a major drop from the 10.4 percent year-over-year growth in 2015. + Also on Network World: When it comes to security, Android is the new Windows + However, that's the total market. For just 4G smartphones, IDC predicts a 21.3 percent year-over-year growth globally for 2016, reaching 1.17 billion units. Much of this growth is coming from emerging markets, such as Asia/Pacific—excluding Japan—Latin America, Central and Eastern Europe, and the Middle East and Africa. Mature markets such as the U.S., Canada, Japan and Western Europe are further along the 4G adoption curve, so the growth is slower.To read this article in full or to leave a comment, please click here

Python Basics – Part 2 cont…

4.Tuples

A tuple is similar to a list. The difference between the two is that we cannot change the elements of a tuple once it is assigned whereas in a list, elements can be changed. A tuple is created by placing all the items (elements) inside a parentheses ()

  • We generally use tuple for different datatypes and list for homogeneous similar datatypes.
  • Since tuple are immutable, means value can not be changed.
  • Tuples that contain immutable elements can be used as key for a dictionary. With list, this is not possible.
  • If you have data that doesn’t change, implementing it as tuple will guarantee that it remains write-protected.

Empty tuples are constructed by an empty pair of parentheses; a tuple with one item is constructed by following a value with a comma (it is not sufficient to enclose a single value in parentheses)

CODE:

tuple1

OUTPUT:

tuple1out

 

 

5 .Dictionary

Python dictionary is an unordered set of key:value pairs , with the requirement that the keys are unique (within one dictionary). A pair of braces creates an empty dictionary: {}.Dictionary have no concept of order among elements.

Keys are unique within a dictionary while values may not be.The values Continue reading
