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.

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.

Security: Uber, Replacing x86 Firmware, 'IoT' and Chromebook

  • Key Dem calls for FTC to investigate Uber data breach

    A key Democrat is calling on the Federal Trade Commission (FTC) to investigate a massive Uber breach that released data on 57 million people, as well as the company's delay in reporting the cyber incident.

  • Multiple states launch probes into massive Uber breach
  • Replacing x86 firmware with Linux and Go

    The problem, Minnich said, is that Linux has lost its control of the hardware. Back in the 1990s, when many of us started working with Linux, it controlled everything in the x86 platform. But today there are at least two and a half kernels between Linux and the hardware. Those kernels are proprietary and, not surprisingly, exploit friendly. They run at a higher privilege level than Linux and can manipulate both the hardware and the operating system in various ways. Worse yet, exploits can be written into the flash of the system so that they persist and are difficult or impossible to remove—shredding the motherboard is likely the only way out.

  • Connected sex-toy allows for code-injection attacks on a robot you wrap around your genitals

    However, the links included base-64 encoded versions of the entire blowjob file, making it vulnerable to code-injection attacks.

  • Chromebook exploit earns researcher second $100k bounty
    For Google’s bug bounty accountants, lightning just struck twice. In September 2016, an anonymous hacker called Gzob Qq earned $100,000 (£75,000) for reporting a critical “persistent compromise” exploit of Google’s Chrome OS, used by Chromebooks. Twelve months on and the same researcher was wired an identical pay out for reporting – yes! – a second critical persistent compromise of Google’s Chrome OS. By this point you might think Google was regretting its 2014 boast that it could confidently double its maximum payout for Chrome OS hacks to $100,000 because “since we introduced the $50,000 reward, we haven’t had a successful submission.” More likely, it wasn’t regretting it at all because isn’t being told about nasty vulnerabilities the whole point of bug bounties?
  • Why microservices are a security issue
    And why is that? Well, for those of us with a systems security bent, the world is an interesting place at the moment. We're seeing a growth in distributed systems, as bandwidth is cheap and latency low. Add to this the ease of deploying to the cloud, and more architects are beginning to realise that they can break up applications, not just into multiple layers, but also into multiple components within the layer. Load balancers, of course, help with this when the various components in a layer are performing the same job, but the ability to expose different services as small components has led to a growth in the design, implementation, and deployment of microservices.

Lumina 1.4 Desktop Environment Debuts with New Theme Engine and ZFS Integrations

Lumina 1.4.0 is a major release that introduces several new core components, such as the Lumina Theme Engine to provide enhanced theming capabilities for the desktop environment and apps written in the Qt 5 application framework. The Lumina Theme Engine comes with a configuration utility and makes the previous desktop theme system obsolete, though it's possible to migrate your current settings to the new engine. "The backend of this engine is a standardized theme plugin for the Qt5 toolkit, so that all Qt5 applications will now present a unified appearance (if the application does not enforce a specific appearance/theme of it’s own)," said the developer in today's announcement. "Users of the Lumina desktop will automatically have this plugin enabled: no special action is required." Read more
