Accelerating Scientific Analysis with the SciDB Open Source Database System

Filed under
OSS
Sci/Tech

Science is swimming in data. And, the already daunting task of managing and analyzing this information will only become more difficult as scientific instruments — especially those capable of delivering more than a petabyte (that’s a quadrillion bytes) of information per day — come online.

Tackling these extreme data challenges will require a system that is easy enough for any scientist to use, that can effectively harness the power of ever-more-powerful supercomputers, and that is unified and extendable. This is where the Department of Energy’s (DOE) National Energy Research Scientific Computing Center’s (NERSC’s) implementation of SciDB comes in.

  • 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.

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

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.

Sci/Tech

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

OSS
Sci/Tech

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.

  • [Video] Linux Audio Programs Compared 2017
    I made this video for those that are new to, or just interested in making music on the Linux OS.

  • Qtox: Open Source and Fully Secure Skype Replacement for Linux
    Long years ago, we've talked about a Skype alternative called Tox which was still in its early developmental stages. Tox was supposed to become the anti-thesis of Skype by being a fully open-source video and voice chat client that placed user privacy and security at its center. Well, guess what, there are now fully active and well-maintained chat clients that are built on top of Tox protocol. qTox is one of them.

  • A Snapshot of Linux Gamers, Just One Year Ago
    It’s about time we share the analysis of that Q1 2016 survey (fielding occured in March last year), especially as we are about to launch the Q1 2017 one pretty, pretty soon. That way we will be able to compare how things have changed over the course of 12 months. As usual, the whole disclaimer about online surveys is valid here (data is only as good as your n size, the appropriateness of your sampling, and the quality of the responses, etc…), but assuming it’s not all that bad and all that unreliable, let’s dig in the results. As a reminder, most of the respondents for this survey were recruited through the r/linux and r/linux_gaming subreddits, as well as the readership of BoilingSteam. This is not our first survey, and you can see our previous ones done in the second quarter of 2015, and the following one in the last quarter of 2015.

  • CodeWeavers Announces CrossOver 16.2.0
  • The Wine Revolution is ON!
    As you know Codeweavers (and other WINE contributors) have been working on DX11 support for a while – they were supposed to have DX11 support by the end of 2016, but as with all complex projects, timelines tend to slip and only very DX11 titles could run a few months ago. Since then, there was no major announcement, but it seems that the progress has been very significant in the recent WINE versions (2.3 is already out).
