Linux at 25: Linus Torvalds on the evolution and future of Linux

The last time I had the occasion to interview Linus Torvalds, it was 2004, and version 2.6 of the Linux kernel had been recently released. I was working on a feature titled “Linux v2.6 scales the enterprise.” The opening sentence was “If commercial Unix vendors weren’t already worried about Linux, they should be now.” How prophetic those words turned out to be.More than 12 years later -- several lifetimes in the computing world -- Linux can be found in every corner of the tech world. What started as a one-man project now involves thousands of developers. On this, its 25th anniversary, I once again reached out to Torvalds to see whether he had time to answer some questions regarding Linux’s origins and evolution, the pulse of Linux’s current development community, and how he sees operating systems and hardware changing in the future. He graciously agreed.To read this article in full or to leave a comment, please click here

New York Public Library reads up on the cloud

Four years ago, the New York Public Library began to move its web properties to the cloud.Today, the library system has all of its approximately 80 web sites in the cloud. The library has shrunk the number of on-premise servers by 40% and is running those web properties 95% more cheaply than if it had bought the hardware and software to do it all by itself.The library took a risk on the cloud, and on Amazon Web Services (AWS), and it paid off."We've grown but we've grown in the cloud," said Jay Haque, director of DevOps and Enterprise Computing at the library. "Today, we're primarily focused on the digital identity of the NYPL. How our properties look. How they merge and integrate. How our patrons use the site … Without the cloud, we wouldn't have the time to focus on the customer experience."To read this article in full or to leave a comment, please click here

Proposed ‘social media ID, please’ law draws outrage

A plan by the U.S. government to require some foreign travelers to provide their social media IDs on key travel documents is drawing outrage.People who responded to the government’s request for comment about the proposal spared little in their criticisms. They call it “ludicrous,” an “all-around bad idea,” “blatant overreach,” “desperate, paranoid heavy-handedness,” “preposterous,” “appalling,” and “un-American.”But the feds are most serious about it.The plan affects people traveling from “visa waiver” countries to the U.S., where a visa is not required. This includes most of Europe, Singapore, Chile, Japan, South Korea, Australia and New Zealand -- 38 countries in total.To read this article in full or to leave a comment, please click here

Data lakes security could use a life preserver

As big data initiatives gain steam at organizations, many companies are creating “data lakes” to provide a large number of users with access to the data they need. And as with almost every type of new IT initiative, this comes with a variety of security risks that enterprises must address.Data lakes are storage repositories that hold huge volumes of raw data kept in its native format until it’s needed. They’re becoming more common as organizations gather enormous amounts of data from a variety of resources.The growing business demand for analytics is helping to fuel the move to large repositories of data. And data lakes are likely to take on even more significance with the growth of the internet of things (IoT), in which companies will gather data from and about countless networked objects.To read this article in full or to leave a comment, please click here

New collision attacks against triple-DES, Blowfish break HTTPS sessions

There is now a practical, relatively fast attack on 64-bit block ciphers that lets attackers recover authentication cookies and other credentials from HTTPS-protected sessions, a pair of French researchers said. Legacy ciphers Triple-DES and Blowfish need to go the way of the broken RC4 cipher: Deprecated and disabled everywhere.Dubbed Sweet32, researchers were able to take authentication cookies from HTTPS-protected traffic using triple-DES (3DES) and Blowfish and recover login credentials to be able to access victim accounts, said the researchers, Karthikeyan Bhargavan and Gaëtan Leurent of INRIA in France. The attack highlights why it is necessary for sites to stop using legacy ciphers and upgrade to modern, more secure ciphers.To read this article in full or to leave a comment, please click here

Experts challenge Skyhigh’s patent for cloud-based encryption gateway

Skyhigh announced today that it has received a patent for its technology, which moves that encryption gateway into a hosted environment.Enterprises looking to protect sensitive data stored in cloud services can funnel user traffic through on-premises encryption gateways that allow them to keep control of their encryption keys. Moving the encryption process to Skyhigh's servers allows for easier access by remote employees, mobile users, business partners, or customers, said Rajiv Gupta, Skyhigh's CEO. He says the company offers these encryption gateways in various locations, allowing customers to comply with data residency and privacy laws.To read this article in full or to leave a comment, please click here

Trying to make sense of Google’s messaging mess

Google appears to finally be trying to clarify its strategies for communication and messaging. However, the company determined it needs more messaging apps — not fewer apps. By the end of this year, Google will maintain at least eight different messaging apps, including Hangouts, Google Messenger, Google Chat, Google Voice, the Jibe rich communication services (RCS) app for carriers, Allo, Duo and the Spaces group-sharing app. Following the early August release of Duo, a new one-to-one video calling app, and the complementary messaging app Allo, which is expected to launch before summer's end, Google says it plans to reposition Hangouts as an enterprise service.To read this article in full or to leave a comment, please click here

Linux’s brilliant career, in pictures

Docker Online Meetup #41: Deep Dive into Docker 1.12 Networking

For this week’s Docker Online Meetup, Sr. Director, Networking at Docker, Madhu Venugopal, joined us to talk about Docker 1.12 Networking and answer questions.

Starting with Docker 1.12, Docker has added features to the core Docker Engine to make multi-host and multi-container orchestration simple to use and accessible to everyone. Docker 1.12 Networking plays a key role in enabling these orchestration features.

In this online meetup, we learned all the new and exciting networking features introduced in Docker 1.12:

  • Swarm-mode networking
  • Routing Mesh
  • Ingress and Internal Load-Balancing
  • Service Discovery
  • Encrypted Network Control-Plane and Data-Plane
  • Multi-host networking without external KV-Store
  • MACVLAN Driver

 

The number of questions Madhu got at the end of the online meetup was amazing and because he did not have time to answer all of them, we’ve added the rest of the Q&A below:

Q: Will you address the DNS configuration in Docker? We have two apps created with docker compose and would like to enable communication and DNS resolution from containers in one of the apps to containers in the other app.

Check out the PTAL external network feature in docker compose in the Docker docs to get started. If that Continue reading

IDG Contributor Network: Shippable ships its newest thing: Industrial strength continuous deployment

Founded back in 2013, Shippable is one of the cool kids in the continuous deployment (CD) space. For those unaware, CD is a movement in which development teams deploy code frequently instead of in irregular and widely spaced occurrences. It is a movement popularized by organizations such as Facebook, Google and Twitter that deploy code many, many times a day.Shippable, therefore builds a platform to reduce friction and therefore allow software development teams to not only ship code fast, but far more frequently as well. DevOps, the movement that brought together the development and operations side of IT departments, aims to increase this velocity.To read this article in full or to leave a comment, please click here

Facebook, Google, Twitter lax on terrorists’ misuse of their sites, say UK MPs

A panel of U.K. lawmakers has described as “alarming” that social networking companies like Facebook, Twitter and Google's YouTube have teams of only a few hundred employees to monitor billions of accounts for extremist content.“These companies are hiding behind their supranational legal status to pass the parcel of responsibility and refusing to act responsibly in case they damage their brands,” said a report released early Thursday in the U.K. by the Home Affairs Committee appointed by the House of Commons.To read this article in full or to leave a comment, please click here
