Microsoft Finally Joins Open Source Eclipse Foundation

EDU OSDCThe software giant was a holdout for years, but is now an official member. In a move that would have been unheard of a few years ago, Microsoft has joined the open source Eclipse Foundation. The organization for a long time counted Microsoft among its short list of major nonparticipants. But with Microsoft now embracing open source and the opportunities it can bring, the company finally climbed on board.

In a blog post, Shanku Niyogi, general manager of the Visual Studio Team, today noted that Microsoft already has worked with Eclipse to improve the Java experience across Microsoft applications and developments services, including on the Microsoft Azure cloud.

How Postgres and Open Source Are Disrupting The Market for Database Management Systems

Open source database management systems (OSDBMSs) have matured into viable alternatives to proprietary, commercial solutions. It comes as no surprise that OSDBMSs are not-so-subtly pushing proprietary solutions to the periphery. According to Gartner’s The State of Open Source RDBMS, 2015, the OSDBMS market is worth $562 million and has grown 31% year over year since 2013.

By contrast, the overall market for database management solutions, valued by IDC to be over $50 billion by 2018, grew by only 5.4% year over year during that same period. In terms of market evolution, Gartner writes: “By 2018, more than 70% of new in-house applications will be developed on an OSDBMS, and 50% of existing relational DBMS instances will have been converted or will be in process.” Id. In other words, the entire definition of the database management system market will shift from commercial, closed-source DBMSs to OSDBMSs – a paradigm shift with decades of future staying power.

The Rise of IoT Hacking: New Dangers, New Solutions

hacking-iotThe explosive growth of the Internet of Things has created a host of new threats for the enterprise. Here’s how hackers are targeting your connected devices and what you can do about it.

…In the enterprise, this danger is compounded as the bridge between traditional IT systems and IoT systems is strengthening, and IT managers can no longer rely on tried-and-true security methods. According to Steve Grobman, CTO at Intel’s Security Group, most organizations don’t have the resources to rebuild their infrastructure from the ground up, so they’re forced to rely on legacy systems that may never have been designed to be connected in the first place, and may therefore contain inherent vulnerabilities.

Thin Mini-ITX SBC Runs Linux on Skylake, Offers Long Lifecycle

Congatec, which was early to announce COM Express modules based on Intel’s 14nm, 6th Generation Core (“Skylakeâ€) processors, has now rolled out a thin Mini-ITX Skylake board. The 170 x 170 x 20mm Conga-IC170 follows other Congatec Mini-ITX boards such as the thin Conga-IC97 board, featuring Intel 5th Gen Core “Broadwell†SoCs, as well as the not-so-thin, but industrial-focused Conga-IGX, built around the AMD G-Series SoC.

The Congatec supports U-series Core processors — the same power-efficient, dual-core 6th Gen models available in most of the Mini-ITX boards listed above. All current Linux and Microsoft Windows operating systems are supported, says Congatec.

Heterogeneous Memory Management Work Is Being Renewed for the Linux Kernel

Back in 2014 is when longtime open-source graphics driver developer Jerome Glisse began pushing his patches for Heterogeneous Memory Management in the Linux kernel, while that work is still ongoing but has now been renewed. 

We last heard an update on Heterogeneous Memory Management (HMM) last summer when Glisse sent out his latest patches. This big patch-set is a helper layer for a device wanting to mirror a process address space into their own MMU. HMM is designed for GPUs and others in needing to support OpenCL 2.0+ for mirroring a process address space. HMM also makes it possible for using the discrete GPU memory in a transparent manner to the application/game and other possible use-cases.

Google Offers Open Source Tool to Help Evaluate Vendor Security

The vendor security evaluation framework provides questions that organizations need to ask to accurately assess a third-party’s security and privacy readiness, Google said.

Google has released a framework to open source that it implements internally to evaluate the security posture of the numerous vendors it uses for various services each year. The company’s Vendor Security Assessment Questionnaire (VSAQ) Framework is a collection of four templates with questions for evaluating the quality of a supplier’s security and privacy practices. By releasing the framework to the open-source community, Google officials said they want to give other organizations an opportunity to do the same kind of evaluation that Google itself does when selecting vendors and suppliers.

Help Integrate GitLab and the Open Science Framework

LIFE scienceFor years, the benefits of open source code development have been self-evident to the software development community: Transparency leads to collaboration, and collaboration leads to better and more secure code. The scientific community is just starting to understand these benefits.

The growing open science movement is using these same lessons to make the scientific process more transparent, so that research findings will be more reproducible. In order to realize the benefits of open science, we must use a wide set of research tools to enable transparency, which will lead to increased discoverability, reuse, and collaboration.

To that end, the Center for Open Science (COS) is funding the development of an integration between GitLab and the Open Science Framework (OSF), and is seeking interested members of the open source community to contribute to this effort.

12 Linux dd, ddrescue and dcfldd command examples

The dd command stands for “data duplicator” and used for copying and converting data. It is very powerful low level utility of Linux which can do much more like;

• Backup and restore the entire hard disk or partition.
• Backup of MBR (Master Boot Record)
• It can copy and convert magnetic tape format, convert between ASCII and EBCDIC formats,swap bytes          and can also convert lower case to upper case.
• It can also be used by Linux kernel make files to make boot images.

Only superuser can run this command because you can face a big data loss due to its improper usage, so you should be very careful while working with this utility. At that moment data loss can convert the dd utility as a “data destroyer” for you. That’s why it is recommended that beginners should not use this command on a production machine until they get familiarity on this. You must make sure that target location must have sufficient space while running this command.

Syntax of dd command

Before we start with some practical work we need to talk about its syntax.

dd if=<source file name> of=<target file name> [Options]

We normally do not explain about syntax but this command syntax require some explanation. The syntax is totally different when compared to many Linux commands we know. In this syntax dd is followed by two things

if=<source> –This is a source from where you want to copy data and ‘if’ stands for input-file.

of=<destination> –This is a source from where you want to write/paste data and ‘of’ stands for output-file.

[options] –These options include, how fast data should be written, what format etc.

Input(source file name) and Output(target file name) in syntax are disks, partitions, files and devices to which you want to write and read data from. There are many options which we will discuss in examples.

Learn Linux dd command with examples

Example 1: Clone one hard disk to another hard disk. This is useful when we are building many machines with same configuration. We no need to install OS on all the machines. Justinstall OS and required software on machine then clone with below example.

 dd if=/dev/sda of=/dev/sdb

Example 2: We can take backup of a partition/complete HDD for future restoration.

Backing up a partition to a file(to my home directory as hdadisk.img)

dd if =/dev/sda2 of=~/hdadisk.img

Restoring this image file in to other machine

dd if=hdadisk.img of=/dev/sdb3

Example 3: Do you feel hdadisk.img is bit big? Use gzip or bzip2 to compress when creating image.
