BSC’s Mont Blanc 3 Puts ARM Inside Bull Sequana Supers

The HPC industry has been waiting a long time for the ARM ecosystem to mature enough to yield real-world clusters, with hundreds or thousands of nodes and running a full software stack, as a credible alternative to clusters based on X86 processors. But the wait is almost over, particularly if the Mont-Blanc 3 system that will be installed by the Barcelona Supercomputer Center is any indication.

BSC has been shy about trying new architectures in its clusters, and the original Mare Nostrum super that was installed a decade ago and that ranked fifth on the Top 500 list when it …

Reading Tech Books Via The All-At-Once Method

I was recently asked by a friend to read and review a book his publisher had just released. This was a technical book on a topic I was keenly interested in, so I was happy to oblige.

I tackled the book in the way that I normally tackle technical books — a chapter a day, or maybe two chapters in a day. Technical books aren’t recreational fiction for me. I want to grasp the contents of technical books to best make use of the information. This often leads to slow reading. I mull over paragraphs and digest.

This time, I broke that habit. I wanted to get this book done quickly. I wanted the information immediately. I didn’t want to take a few weeks to get through it. Thus, I tried reading the book all at once.

Surprisingly, this worked out well. I ended up getting through the book in four sittings, which perhaps doesn’t sound like “all at once.” Bear with me. The first sitting was a single chapter. The second sitting was a single chapter. Then came the holidays and a complete disruption to my workflow. And then came the epiphany as I stared at the book post-holidays. Continue reading

Syslog-ng Configuration For Newbies

Some time ago I was asked by my friend to recommend a cost-free solution that he could use for storing logs of his security device over network. The Linux OS with installed syslog-ng is perfectly suitable for this job because it can collect logs from any source, process them in near real-time and deliver them to a wide variety of destinations. However it was challenge to explain all the steps in an easy manner as he was a total newbie in a Linux world. For this reason I wrote a basic installation and configuration manual for him which I share with you. The manual helps you to setup syslog-ng on Ubuntu server and troubleshoot the possible issues.

1. Install Ubuntu 16.04 Server Edition

During Ubuntu installation you are asked to provide the username/password and IP settings. Once an installation process finishes, the system is rebooted. when you get your console again, login and install updates with the command:

$ sudo su
# apt-get update
# apt-get upgrade

2. Install and Configure Syslog-ng

# apt-get install syslog-ng

First, you need to download a simple configuration file that I created for you.

# cd /etc/syslog-ng/conf.d
# wget http://brezular.com/wp-content/uploads/2016/12/firewals.conf_.txt -O firewals.conf

Lavabit developer has a new encrypted, end-to-end email protocol

The developer behind Lavabit, an email service that noted leaker Edward Snowden used, is releasing source code for an open-source end-to-end encrypted email standard that promises surveillance-proof messaging. The code for the Dark Internet Mail Environment (DIME) standard will become available on Github, along with an associated mail server program, said its developer Ladar Levison on Friday. DIME will work across different service providers and perhaps crucially will be "flexible enough to allow users to continue using their email without a Ph.D. in cryptology," said Levison. To coincide with its launch, Levison is also reviving Lavabit. The encrypted email service shut down in 2013 when federal agents investigating Snowden demanded access to email messages of his 410,000 customers, including their private encryption keys.To read this article in full or to leave a comment, please click here

The command-line, for cybersec

On Twitter I made the mistake of asking people about command-line basics for cybersec professionals. A got a lot of useful responses, which I summarize in this long (5k words) post. It’s mostly driven by the tools I use, with a bit of input from the tweets I got in response to my query.

bash

By command-line this document really means bash.

There are many types of command-line shells. Windows has two, 'cmd.exe' and 'PowerShell'. Unix started with the Bourne shell ‘sh’, and there have been many variations of this over the years, ‘csh’, ‘ksh’, ‘zsh’, ‘tcsh’, etc. When GNU rewrote Unix user-mode software independently, they called their shell “Bourne Again Shell” or “bash” (queue "JSON Bourne" shell jokes here).

Bash is the default shell for Linux and macOS. It’s also available on Windows, as part of their special “Windows Subsystem for Linux”. The windows version of ‘bash’ has become my most used shell.

For Linux IoT devices, BusyBox is the most popular shell. It’s easy to clear, as it includes feature-reduced versions of popular commands.


man

‘Man’ is the command you should not run if you want help for a command.

Apple sues Qualcomm over patent licensing and $1B in payments

A nasty spat between Apple and Qualcomm broke into public view on Friday when the smartphone maker accused the chip supplier of charging "exorbitant" licensing fees for its cellular technology.Apple is asking a Southern California court to order Qualcomm to pay it nearly $1 billion that it says Qualcomm is holding back. Apple says it is owed the money but Qualcomm is holding it back because Apple cooperated with a South Korean government investigation into Qualcomm's licensing practices.The lawsuit alleges that Qualcomm charges high licensing fees to the companies that make iPhones for Apple. Those companies pass the fees on to Apple but aren't allowed to show Apple the specifics of the licensing deals, leaving Apple unsure what it is paying for.To read this article in full or to leave a comment, please click here

New details emerge about Intel’s super-small Euclid computer for robots

Intel is getting proficient at developing small computers. First, came its Compute Sticks and then its credit-card-shaped Compute Cards.But nothing's quite like the mysterious Euclid, which is a self-contained computer the size of a thumb designed to be the brains and eyes of a robot.More details have emerged about the computer, which was announced in August and has yet to be released.The Euclid is so small and light that's possible to hold like a pen. It has a built-in 3D RealSense camera, making it like a PC fused into a Microsoft Kinect.The design makes it possible to install the Euclid where the eyes of a human-like robot would be typically placed. The 3D RealSense camera will act as the eyes of a robot, capturing images in real-time and helping with movement.To read this article in full or to leave a comment, please click here

Microsoft will soon end Office 2013 distribution through Office 365

Get ready, Office 365 administrators: Microsoft is ending support for the Office 2013 client apps that it previously distributed through its cloud-based productivity service.

Microsoft also won’t release feature updates for those products, and won’t provide support through Customer Service Support or Premier Support.To read this article in full or to leave a comment, please click here

Researchers propose a way to use your heartbeat as a password

Researchers at Binghamton State University in New York think your heart could be the key to your personal data. By measuring the electrical activity of the heart, researchers say they can encrypt patients' health records.  The fundamental idea is this: In the future, all patients will be outfitted with a wearable device, which will continuously collect physiological data and transmit it to the patients' doctors. Because electrocardiogram (ECG) signals are already collected for clinical diagnosis, the system would simply reuse the data during transmission, thus reducing the cost and computational power needed to create an encryption key from scratch.To read this article in full or to leave a comment, please click here

Augmented reality is more than just holograms

Holographic headsets are a central theme to augmented reality (AR) today, but the recent AR in Action Conference demonstrated the diversity of the field and the potential to include many more technologies to augment humans. The AR in Action Conference, held at the MIT Media Lab, expanded the definition of AR through a TED conference-like lens, delivering 70 diverse curated talks and 32 panels over two days to over 1,000 experts and practitioners in the field. As Chris Croteau, general manager of Intel’s Wearable Device Group, said: “A liberal definition of AR focuses on the way data is presented to users and how they interact with it. The popular definition of the AR platform as a holographic projection system like the Hololens, Meta and ODG headsets limits what AR can be.”To read this article in full or to leave a comment, please click here

Cluster HAT, the easiest way to build a Raspberry Pi Zero cluster

I recently compiled a list of Raspberry Pi clusters and reader Alex Hortin wrote in to suggest I looked at a cluster framework for up to four Raspberry Pi Zeros called the Cluster HAT produced by 8086 Consultancy. In case you haven’t come across the term, the “HAT” part of Cluster HAT, means that the device implements the Raspberry Pi Foundation’s Hardware Attached on Top system for add-on hardware. The Foundation’s 2014 blog post announcing the standard explains:To read this article in full or to leave a comment, please click here

As the the leader of Deloitte’s analytics practice, Paul Roma directs the company's analytics offerings across all businesses, so he sees companies struggling with a range of issues.  Network World Editor in Chief John Dix recently talked to Roma about everything from what analytics problems companies are facing (Hint: the swamp reference above), to tools that help extract more value (cognitive analytics and machine learning), and even the executive management roles that are evolving (the title doesn’t matter much, but ownership of the problem does).  Deloitte Paul Roma, Chief Analytics Officer, DeloitteTo read this article in full or to leave a comment, please click here

Worth Reading: Content delivery networks move data closer to the edge

Content delivery networks (CDNs) are the new “middleware” that connect the users who work and live at the network’s endpoints with the bulk of data resources that are increasingly centralized in the cloud. Many industry watchers admit being caught by surprise as the expected decline in “hyperscale” data centers failed to materialize. Data centers continue to grow in size, but the total number of data centers hasn’t declined as expected, according to an article in Data Center Knowledge. —The New Stack
