LWN at GUADEC
At GUADEC 2016 in Karlsruhe, Germany, Daniel "grindhold" Brendle presented his work developing a new library and widget set that will allow GTK+ applications to implement flowgraphs in a standard manner. The widget set would enable applications to provide interactive widgets for linking filters and other block-oriented components—a type of interface many applications currently need to reinvent on their own.
Flowgraphs, Brendle explained, are a general-purpose diagramming technique that many people will recognize from textbooks and other printed matter. They show how objects, information, and signals flow through some sort of process. Biology textbooks use them to illustrate circulation in the body, technical manuals use them to show how a manufacturing process runs, and so on. In software, he said, they are most familiar as the node-and-pipe diagrams that illustrate signal processing or data filtering.
At GUADEC 2016 in Karlsruhe, Germany, Bastien Ilsø and Carlos Soriano reported on the revamped Newcomers section of the GNOME web site. The section is intended to draw in new users and developers and help them find their way around the project as well as to help them get the necessary development environment set up to begin contributing code.
The stock of pacemaker manufacturer St. Jude Medical Inc (STJ.N) fell sharply on Thursday after short-selling firm Muddy Waters said it had placed a bet that the shares would fall, claiming its implanted heart devices were vulnerable to cyber attacks.
St. Jude, which agreed in April to sell itself for $25 billion to Abbott Laboratories (ABT.N), said the allegations were false. St Jude shares closed down 4.96 percent, the biggest one-day fall in 7 months and at a 7.4 percent discount to Abbott's takeover offer.
Muddy Waters head Carson Block said the firm's position was motivated by research from a cyber security firm, MedSec Holdings Inc, which has a financial arrangement with Muddy Waters. MedSec asserted that St. Jude's heart devices were vulnerable to cyber attack and were a risk to patients.
On a move to counter distros like Kali Linux and BackBox, BlackArch has got a new ISO image that includes more than 1,500 hacking tools. The update also brings several security and software tweaks to deliver an enhanced platform for various penetration testing and security assessment activities.
The new BlackArch Linux ISO includes an all new Linux installer and more than 100 new penetration testing and hacking tools. There is also Linux 4.7.1 to fix the bugs and compatibility issues of the previous kernel. Additionally, the BlackArch team has updated all its in-house tools and system packages as well as updated menu entries for the Openbox, Fluxbox and Awesome windows managers.
Intel has the kind of control in the datacenter that only one vendor in the history of data processing has ever enjoyed. That other company is, of course, IBM, and Big Blue wants to take back some of the real estate it lost in the datacenters of the world in the past twenty years.
The Power9 chip, unveiled at the Hot Chips conference this week, is the best chance the company has had to make some share gains against X86 processors since the Power4 chip came out a decade and a half ago and set IBM on the path to dominance in the RISC/Unix market.
IBM laid out a roadmap out past 2020 for its Power family of processors back at the OpenPower Summit in early April, demonstrating its commitment the CPU market with chips that are offer a brawny alternative to CPUs and accelerators compared to the Xeon and Xeon Phi alternatives from Intel and the relatively less brawny chips from ARM server chip makers such as Applied Micro and Cavium and the expected products from AMD, Broadcom, and Qualcomm. We pondered IBM’s prospects in the datacenter in the wake of some details coming out about next year’s Power9 processors, which IBM said at the time would come in two flavors, one aimed at scale-out machines with one or two sockets and another aimed at scale up machines with NUMA architectures and lots of sockets and shared memory.
Today ARM is announcing an update to their line of architecture license products. With the goal of moving ARM more into the server, the data center, and high-performance computing, the new license add-on tackles a fundamental data center and HPC issue: vector compute. ARM v8-A with Scalable Vector Extensions won’t be part of any ARM microarchitecture license today, but for the semiconductor companies that build their own cores with the instruction set, this could see ARM move up into the HPC markets. Fujitsu is the first public licensee on board, with plans to include ARM v8-A cores with SVE in the Post-K RIKEN supercomputer in 2020.
I have always been a big fan of Docker. This is very visible if you regularly read this blog. However, I am very disappointed lately how Docker handled the 1.12 release. I like to think of version 1.12 as a great proof of concept that should not have received the amount of attention that it already received. Let’s dive deep into what I found wrong.
First, I do not think a company should market and promote exciting new features that have not been tested well. Every time Docker makes an announcement, the news spreads like a virus to blogs and news sites all over the globe. Tech blogs will basically copy and paste the exact same procedure that Docker discussed into a new blog post as if they were creating original content. This cycle repeats over and over again and becomes annoying because I am seeing the same story a million times. What I hate most about these recent redundant articles is that the features do not work as well as what is written about them.
The tech industry is full of exciting trends that promise to change the face of the industry and business as we know it, but one that is gaining a huge amount of focus is containers.
However, problems lie with the technology and threaten to root itself deep in the mythology about it, namely the misconceptions over what the technology is, what can be done with it, and the idea that they replace virtual machines.
Lars Herrmann, GM, Integrated Solutions at Red Hat spoke to CBR about five common misconceptions, but first the benefits.
Herrmann, said: “Containerisation can be an amazingly efficient way to do DevOps, so it’s a very practical way to get into a DevOps methodology and process inside an organisation, which is highly required in a lot of organisations because of the benefits in agility to be able to release software faster, better, and deliver more value.”
The company released Rackspace Private Cloud powered by Red Hat in February. Using the Hat Enterprise Linux OpenStack Platform, the product helped extend Rackspace's OpenStack-as-a-service product slate.
It has only been six short months since SoylentNews' Folding@Home team was founded, and we've made a major milestone: our team is now one of the top 500 teams in the world! We've already surpassed some heavy hitters like /. and several universities, including MIT. (But now is not the time to rest on our laurels. A certain Redmond-based software producer currently occupies #442.)
In case you aren't familiar with folding@home, it's a distributed computing project that simulates protein folding in an attempt to better understand diseases such as Alzheimer's and Huntington's and thereby help to find a cure. To that end, SoylentNews' team has completed nearly 16,000 work units.
Games for GNU/Linux
I really love the visuals in Fossil Echo! Sadly it wasn't a day-1 release, but the developers have stated that they're working hard on it.
I love indie games, as they tend to do gameplay larger studios won't touch. The Final Station is another such brilliant idea I really want to play.
