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.

Why the creators of the Julia programming language just launched a startup

Filed under

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.”

World record set for 100 TB sort by open source and public cloud team

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.

Lightweight DBMS guides Linux-based cow feeding robot

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.

It was a pretty long project. I didn’t work on it full time, obviously, but I probably worked on it over a period of six months, and most of the time was writing the software. A lot of the software was written in Python – like the controls for the webcam, the soundboard and everything – so most of the time was getting the software running and getting the kinks worked out. Like where if it loses a Wi-Fi connection it tries to rejoin and things like that. So, yeah, I definitely want to revisit it, and obviously the second time round you can do it a lot better than you did the first, so I’d like to go back.

Leftovers: Ubuntu

  • The Simply Ubuntu Desktop
    Over on Flickr, fosco_ submitted this simple Ubuntu desktop, with just a few things tweaked for a cleaner experience. Like we’ve said, sometimes less is more, and this desktop makes good use of a few widgets to make a great UI even better.
  • HP Linux Imaging and Printing 3.16.5 Supports Ubuntu 16.04 LTS and Debian 8.4
    The team of developers behind the HPLIP (short for HP Linux Imaging and Printing) project, announced a few moments ago the availability of the fifth maintenance build in the 3.16 stable series of the software. For those of you who are not in the loop, HP Linux Imaging and Printing is an open-source initiative to bring the latest HP (Hewlett-Packard) printer drivers to GNU/Linux operating systems. The software has a pretty active development team working behind it, releasing maintenance builds at least once a month.
  • Convergence delayed: Unity 8 won’t be the default desktop in Ubuntu 16.10
    Canonical’s vision of convergence—a single, highly adaptive environment that spans mobile and desktop uses—has been delayed yet again. The Unity 8 desktop and Mir display server, which are key to that vision, won’t be used by default in Ubuntu 16.10, according to discussion in the Ubuntu Online Summit.

Bufferbloat Is Still Being Fought In Linux Kernel, Another Big Improvement Queued

Bufferbloat is the excess buffering of packets resulting in high latency, jitter, and lower network throughput. There's been efforts to battle bufferbloat within the Linux kernel going back a long time while this week another new patch has surfaced. A Phoronix reader pointed out to us a patch that's now been queued up in net-next for Linux 4.7 and could end up being back-ported to Linux stable releases.
