Entroware's New Linux Workstation Rocks Ryzen Threadripper And 4x Nvidia RTX GPUs

Filed under
GNU
Linux
Hardware

The Entroware Hades also has the distinction of being the company's first AMD system, and includes 5 different Ryzen Threadripper options for those who don't want any compromises when it comes to ripping threads: Ryzen TR 1900X (8 cores, 16 threads) all the way up to the Ryzen TR 2990WX (32 cores, 64 threads).

I don't immediately see any weaknesses here, beyond the sticker shock when scaling up the hardware loadouts. The Hades begins with the Fractal Design FD-CA-DEF-R6C-BK case. Connectivity on the front ports is ample, with 2x USB 2.0, 2x USB 3.0 and 1 USB 3.0 Type-C port, as well as standard headphone and mic inputs. Moving to the back, you've got a total of eight USB SuperSpeed 3.1 ports (plus two additional ones at 10Gbps), 5x audio jacks, dual Gigabit Ethernet ports and a dual-antenna Intel Wireless-AC connection.

The minimum Hades loadout is perhaps too anemic for a workstation with this much capability, and it's admittedly a system you could assemble yourself for less. For the baseline price tag of about 1770 Euros (including tax) you'll get a 3-year warranty, a Ryzen Threadripper 1900X, 16GB of DDR4 RAM at 2933MHz, a 120GB SSD, a GeForce GT 1030 and Ubuntu or Ubuntu MATE 18.04/18.10.

Raspberry Pi DAQ HAT can stack eight high

Filed under
Hardware

MCC’s “MCC152” is a stackable Raspberry Pi voltage output and digital I/O HAT with dual 0-5 V analog outputs at up to 5 kS/s and 8x configurable DIO. An open source C++ and Python library is also available.

In August, Measurement Computing Corp. (MCC) launched its MCC 118 voltage measurement DAQ HAT for the Raspberry Pi with eight ±10 V inputs and sample rates up to 100 kS/s. It has now released a promised MCC 152 voltage output and digital I/O HAT that can be stacked along with the MCC 118 and future MCC HATS in configurations of up to eight boards.

  • Interview with Patrik Ohldin of Open Source Metal 3D Printing Company Freemelt

    I’ve known Patrik Ohldin for a long time as a supremely knowledgeable metal printing guy. He’s been working in metal 3D printing for over 14 years, 12 of those as an Area Sales Manager for Swedish EBM metal printing company and now GE subsidiary Arcam. He really knows a tonne about EBM and electron beam powder bed fusion technologies. He is also a stand-up guy that knows how to explain, educate and understand business cases in a wide array of areas. Patrik was instrumental in introducing EBM to new areas such as aerospace and orthopedic implants and helped many firms industrialize metal 3D printing. After more than 12 years of selling EBM machines worldwide and being a key player in EBM’s conquest of foreign markets, Patrik co-founded open source electron beam powder bed fusion company Freemelt.

Server: HTTP Clients, IIS DDoS and 'DevOps' Hype From Red Hat

  • What are good command line HTTP clients?
    The whole is greater than the sum of its parts is a very famous quote from Aristotle, a Greek philosopher and scientist. This quote is particularly pertinent to Linux. In my view, one of Linux’s biggest strengths is its synergy. The usefulness of Linux doesn’t derive only from the huge raft of open source (command line) utilities. Instead, it’s the synergy generated by using them together, sometimes in conjunction with larger applications. The Unix philosophy spawned a “software tools” movement which focused on developing concise, basic, clear, modular and extensible code that can be used for other projects. This philosophy remains an important element for many Linux projects. Good open source developers writing utilities seek to make sure the utility does its job as well as possible, and work well with other utilities. The goal is that users have a handful of tools, each of which seeks to excel at one thing. Some utilities work well independently. This article looks at 4 open source command line HTTP clients. These clients let you download files over the internet from the command line. But they can also be used for many more interesting purposes such as testing, debugging and interacting with HTTP servers and web applications. Working with HTTP from the command-line is a worthwhile skill for HTTP architects and API designers. If you need to play around with an API, HTTPie and curl will be invaluable.

  • 5 things to master to be a DevOps engineer
    There's an increasing global demand for DevOps professionals, IT pros who are skilled in software development and operations. In fact, the Linux Foundation's Open Source Jobs Report ranked DevOps as the most in-demand skill, and DevOps career opportunities are thriving worldwide. The main focus of DevOps is bridging the gap between development and operations teams by reducing painful handoffs and increasing collaboration. This is not accomplished by making developers work on operations tasks nor by making system administrators work on development tasks. Instead, both of these roles are replaced by a single role, DevOps, that works on tasks within a cooperative team. As Dave Zwieback wrote in DevOps Hiring, "organizations that have embraced DevOps need people who would naturally resist organization silos."

Purism's Privacy and Security-Focused Librem 5 Linux Phone to Arrive in Q3 2019

Initially planned to ship in early 2019, the revolutionary Librem 5 mobile phone was delayed for April 2019, but now it suffered just one more delay due to the CPU choices the development team had to make to deliver a stable and reliable device that won't heat up or discharge too quickly. Purism had to choose between the i.MX8M Quad or the i.MX8M Mini processors for their Librem 5 Linux-powered smartphone, but after many trials and errors they decided to go with the i.MX8M Quad CPU as manufacturer NXP recently released a new software stack solving all previous power consumption and heating issues.

Hack Week - Browsersync integration for Online

Recently my LibreOffice work is mostly focused on the Online. It's nice to see how it is growing with new features and has better UI. But when I was working on improving toolbars (eg. folding menubar or reorganization of items) I noticed one annoying thing from the developer perspective. After every small change, I had to restart the server to provide updated content for the browser. It takes few seconds for switching windows, killing old server then running new one which requires some tests to be passed. Last week during the Hack Week funded by Collabora Productivity I was able to work on my own projects. It was a good opportunity for me to try to improve the process mentioned above. I've heard previously about browsersync so I decided to try it out. It is a tool which can automatically reload used .css and .js files in all browser sessions after change detection. To make it work browsersync can start proxy server watching files on the original server and sending events to the browser clients if needed. Read more
