  • Carl Sagan's solar-powered spacecraft is in trouble
  • Software Glitch Pauses LightSail Test Mission

    But inside the spacecraft's Linux-based flight software, a problem was brewing. Every 15 seconds, LightSail transmits a telemetry beacon packet. The software controlling the main system board writes corresponding information to a file called beacon.csv. If you’re not familiar with CSV files, you can think of them as simplified spreadsheets—in fact, most can be opened with Microsoft Excel.

There is one project called the LHC Open Network Environment (LHCONE) that was originally conceived to help with operations that involved multiple centers. To understand this, though, I have to explain the structure of the data and computing facilities.

Sci/Tech

And Julia is a big deal — it’s a free alternative to proprietary tools for doing data science, like MathWorks’ MATLAB and Wolfram’s Mathematica, and it’s more contemporary than open-source languages R and Python. More companies are hiring data scientists to make more data-driven decisions, and open-source tools often come in handy.

Ubuntu

Ligo (Laser Interferometer Gravitational Wave Observatory) may not get the same kind of attention in the media as other physics experiments, but it should. It's designed to detect gravitational waves, and it looks like the scientists are also using Linux (Ubuntu) to do that.

He said instead of software’s inherent value being its cost, it was better as a means to an end. “The value isn’t in the software, it’s in the utility that the software provides.”

“My call to action is ... is there something in your portfolio of products or services that you can open source.”

In October 2014, Databricks participated in the Sort Benchmark and set a new world record for sorting 100 terabytes (TB) of data, or 1 trillion 100-byte records. The team used Apache Spark on 207 EC2 virtual machines and sorted 100 TB of data in 23 minutes.

In comparison, the previous world record set by Hadoop MapReduce used 2100 machines in a private data center and took 72 minutes. This entry tied with a UCSD research team building high performance systems and we jointly set a new world record.

Sci/Tech

Ittia announced a design win for its lightweight embedded DB SQL database in Wasserbauer’s uClibc Linux based “Butler Gold” robot designed to feed cattle.

The Ittia DB SQL database and its antecedents, including .db*, have shipped in a wide variety of devices, including a circa 2005, Linux-based Oshkosh A3 HEMTT tactical truck. The lightweight, Linux- and Android-compatible embedded relational database has now found its way into barnyard life in its role within a Butler Gold cattle-feeding robot from Germany’s Wasserbauer GmbH. Linux has previously played a role in DeLaval’s Voluntary Milking System robot for cattle, but this is the first time we’ve seen it helping out on the other end.

Software and Games: Hegemon, Gift of Parthax, Lutris

  • Hegemon – A Modular System Monitor Application Written In Rust
    When it comes to monitor running processes in Unix-like systems, the most commonly used applications are top and htop, which is an enhanced version of top. My personal favorite is htop. However, the developers are releasing few alternatives to these applications every now and then. One such alternative to top and htop utilities is Hegemon. It is a modular system monitor application written using Rust programming language.
  • Wizard arena-fighter 'Gift of Parthax' is now officially out on Linux
    Announced yesterday after a pretty short beta period, the magical arena fighting game Gift of Parthax is now officially available for Linux. Along with putting the Linux build out in public, their latest release also fixes a few bugs. The developer sent over a key and I've been testing it, the Linux version seems to be working really quite nicely. If you liked the idea of Wizard of Legend, but found it a little too fast for your tastes then Gift of Parthax might be a better fit although it's single-player only.
  • Lutris 0.4.20 is now out, to help you manage all your games plus some Overwatch testing
    I have to admit, the game manager Lutris [Official Site] has come along quite a bit since I last used it. Today, version 0.4.20 was made available. For those not aware of it, Lutris is an application that aims to give you a single place to manage all your games on Linux. It supports native games, Wine, various emulators and so on. The application itself is available under the GPL and the helper scripts to install games can be viewed before using them so it's quite nice.

  • Editor's Corner—Open source is not 'one size fits all' [Ed: But that's a plus, not a minus. With proprietary software it's one unsuitable thing for everything; doesn't scale.]
    Open source communities are no doubt playing a key role in moving the telecommunications industry forward, but not everyone is on board the bandwagon. Over the past five months or so, we've spent a fair amount of time writing about open source groups and standards development organizations (SDOs) such as the Linux Foundation, MEF, Open Networking Foundation, OpenDaylight, the TM Forum and ETSI, and there's clearly more cooperation afoot for the good of the industry. But artificial intelligence startup B.Yond's chief marketing officer, Rikard Kjellberg, said his company has to be careful when it comes to choosing which open source community to commit its resources to. Kjellberg spoke to FierceTelecom on the heels of the AT&T Spark conference earlier this month.

  • Daniel Stenberg: The Polhem prize, one year later
    Family and friends have gotten a rudimentary level of understanding of what curl is and what it does. I'm not suggesting they fully grasp it or know what an "internet protocol" is now, but at least a lot of people understand that it works with "internet transfers". It's not like people were totally uninterested before, but when I was given this prize - by a jury of engineers no less - that says this is a significant invention and accomplishment with a value that "can not be overestimated", it made them more interested. The little video that was produced helped:
  • Open Source Voice Assistant, Mycroft AI, Named Top Deal By KingsCrowd
  • Service providers increasingly adopt open source for their networks
    Communications service providers (CSPs) are increasingly keen to adopt open source technologies to deliver their services, according to research. At this week’s Open Networking Summit Europe in Amsterdam, delegates heard that DevOps, automation, cloud, big data and analytics, software-defined networking (SDN), and management and orchestration (MANO) were increasingly being supported by open source solutions. Commissioned research questioned 150 CSP representatives across 98 companies worldwide. It found that 98% of CSPs are “confident” that open networking solutions can achieve the same level of performance as traditional networking solutions.

    In other Firefox news, the browser evidently is collecting telemetry data via hidden add-ons, ITWire reports. The ITWire post also quotes Mozilla's Marshall Eriwn, director of Trust and Security: "...we will measure Telemetry Coverage, which is the percentage of all Firefox users who report telemetry. The Telemetry Coverage measurement will sample a portion of all Firefox clients and report whether telemetry is enabled. This measurement will not include a client identifier and will not be associated with our standard telemetry."
  • This “Netflix For Open Source” Startup Helps Programmers Get Paid

  • Portable Computing Language 1.2 Released For OpenCL On CPUs & More
    The Portable Computing Language (a.k.a. POCL or PortableCL) is the effort for getting OpenCL running on CPUs as well as other hardware for this open-source code-base that supports OpenCL 1.2 with some OpenCL 2.0+ functionality. The main "feature" of POCL 1.2 is support for LLVM Clang 7.0 as previously the support was limited to LLVM 6.0, but now this new version of LLVM is supported. The HWLOC 2.0 library is also now supported. There are also some minor feature additions like device-side printf being supported.

Comparing the two versions shows many important changes. The new version is much clearer and more worked-out, but there are also significant material changes. In particular the goal has changed dramatically.
