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:

OUTPUT:

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

Senators fail to stop new rules allowing US law-enforcement hacking

Three senators' efforts to stop a major expansion of U.S. law enforcement agencies' hacking powers has failed for now.Proposed changes to Rule 41, the search-and-seizure provision in the Federal Rules of Criminal Procedure, will go into effect Thursday barring any last-minute action in Congress. The rules change will give U.S. law enforcement agencies the authority to cross jurisdictional lines and hack computers anywhere in the world during criminal investigations. Until now, the rules, in most cases, prohibited federal judges from issuing a search warrant outside their jurisdictions. To read this article in full or to leave a comment, please click here

Lenovo Drives HPC From The Middle Ground

While we all spend a lot of time talking about the massive supercomputers that cultivate new architectures, and precisely for that reason, it is the more modest cluster that makes use of these technologies many years hence that actually cultivates a healthy and vibrant HPC market.

Lenovo picked up a substantial HPC business when it acquired IBM’s System x server division two years ago and also licensed key software, such as the Platform Computing stack and the GPFS file system, to drive its own HPC agenda. The Sino-American system maker has been buoyed by higher volume manufacturing thanks to the …

Security products among the most vulnerable software

Why do you spend the big bucks for security products? For protection, right? But many of the top security vendors utilize open-source or third-party components and libraries that are seemingly packed with vulnerabilities.While this is something you already know, a new report found that security products are some of the most vulnerable software. Flexera Software, which acquired Secunia in 2015, noted that between August and October of 2016, 46 products made it to the top 20 most vulnerable products. Eleven of those software products overflowing with vulnerabilities were security-related products.To read this article in full or to leave a comment, please click here

Liveblog: Introduction to Managed Database Services on AWS

This is a liveblog of the AWS re:Invent session titled “Introduction to Managed Database Services on AWS” (DAT307). The speakers for the session are Steve Hunt, Alan Murray, and Robin Spira, all of FanDuel; and Darin Briskman, from AWS Database Services.

Briskman kicks off the session with a quick review of AWS’ managed database offerings. These fall into four categories, which Briskman reviewed so quickly I couldn’t capture. I think they were SQL, NoSQL, data warehousing, and something else. Why use managed databases? Because this allows AWS to take over the responsibility for OS maintenance, DB maintenance, high availability, scalability, etc. All you have to worry about it is the application that runs on the database.

What are the managed relational database services that AWS offers?

• Amazon RDS (Relational Database Service): The oldest service, now supporting MySQL, MariaDB, PostgreSQL, Microsoft SQL Server, and Oracle
• Amazon Aurora: MySQL-compatible (and now PostgreSQL-compatible per the announcement today) with greater scalability, better performance, transparent encryption, high availability, and integration with AWS Lambda

Relational databases are really helpful in many cases, but sometimes NoSQL databases would be more helpful. AWS also offers DynamoDB, which is a managed NoSQL database service. DynamoDB is always clustered, and Continue reading
