  • In iMasons Talk, Scott McNealy Reflects on Sun, Open Source

    In the world of data centers, the Sun casts a long shadow. The legacy of Sun Microsystems is seen today in the data center teams of the world’s largest technology companies.

    Dozens of those alumni of Sun Microsystems took part in the Infrastructure Masons Leadership Summit, held April 19 at Microsoft’s Sunnyvale campus, which brought together more than 100 thought leaders from the data center and cloud industries. The event featured a Q-and-A with Sun co-founder and CEO Scott McNealy, plus several think tank sessions on the future direction of the Internet, which brought reminders how the echoes of Sun’s corporate mantra – “The Network is the Computer” –  can be seen in the emergence of distributed computing.

    The Infrastructure Masons is a group founded by Uber executive Dean Nelson to “unite the builders of the Digital Age.” But the group also looks to the past for lessons that can inform the road ahead.

  • ETSI in midst of figuring out role with open source

    In case there was any doubt, discussion at the Layer 123 NFV & Zero Touch World Congress provided further evidence that the members of the standards world—which has driven wireless technology for decades and the open source that operators are embracing nowadays—are still trying to figure out their relationships with one another.

    Luis Jorge Romero, director general at the standards organization European Telecommunications Standards Institute (ETSI), brought it up during a keynote Thursday that sparked an interchange during Q&A. Romero said he’s heard many comments that standards are over with because, of course, everything is open source, and he hears questions like: “What are you going to do the day after tomorrow?”

  • syslog-ng vs. systemd’s journald

    People often ask me what to use: systemd’s journald or syslog-ng? The quick answer is that most likely both, but it depends on how you use your computer(s). If you have a single standalone machine, journald is probably enough. There is even a nice desktop application to view the logs in the journal. But once you have multiple machines to manage, using syslog-ng has many advantages.

    Even if you use syslog-ng, local system logs are collected by journald. It is an integral part of systemd and cannot be uninstalled. Luckily, syslog-ng can read log messages from the journal. If journald stores additional name-value pairs about an event, syslog-ng can read those as well.

    So, why install syslog-ng? The short answer is: central logging.

Linux
OSS

Open source network-monitoring tools continue to gain in popularity, and Observium came up on our radar as an enterprise-grade offering. Deployed worldwide by large organizations like eBay, PayPal, Twitter and the US Department of Energy, Observium is capable of handling tens of thousands of devices. The client list is impressive, but our test reveals what’s really under the hood.

Observium runs on Linux but can monitor Windows and many other device types. The vendor recommends running Observium on Ubuntu/Debian, but it will also work on distros such as Red Hat/CentOS.

The concept of machine learning, which is a subset of artificial intelligence, has been around for some time. Ali Ghodsi, an adjunct professor at UC Berkeley, describes it as “an advanced statistical technique to make predictions on a massive amount of data.” Ghodsi has been influential in areas of Big Data, distributed systems, and in machine learning projects including Apache Spark, Apache Hadoop, and Apache Mesos. Here, he shares insight on these projects, various use-cases, and the future of machine learning.

How to decide whether to open source your SaaS solution

Filed under
OSS

The decision to open source code requires a fair bit of planning if you want to do it right, especially when it comes to user support and documentation. In the case of SaaS, the required planning is different, although it shares some factors with any open source effort. In my series, How to Make Money from Open Source Platforms, I focused on software that exists solely to be deployed on a computer, whether on a local machine, in a data center, or in a cloud platform (yes, I know the last two are redundant).

There was a simple reason for this focus: It was what I knew. In my career, I have always worked with software, of commercial and community origins, to be installed somewhere. Now I work directly with engineers who take software designed to work solely on their website and with their particular infrastructure, automation, and orchestration. The fact they have been able to take this software and offer it to others in a way that is not only usable but can actually power other businesses is a testament to their commitment to an open source world.

    I spent the last seven days attending Libre Graphics Meeting in sunny and beautiful Seville. This was my second LGM, the first being six years ago in Vienna, so it was refreshing to be back. I stayed in one of the GIMP apartments near the Alameda de Hércules garden square. Being right in the middle of the city meant that everything of interest was either within walking distance or a short bus ride away.

This is what it's like using only open-source software on Android

Filed under
Android
OSS

Technically speaking, Android is open-source. This means anyone can look at the operating system's code, or change it - this is how OEMs like HTC and Samsung add their own tweaks. That openness has often been a rallying cry for hardcore Android enthusiasts. Why use a closed platform like iOS, when you can have a free and open-source platform?

But even from the beginning, there were components of Android that were closed-source. The Gmail app, Maps, Google Talk, and the Play Store were some of the earliest examples. To combat the always-present fragmentation of Android, Google offers many APIs through the Play Services Framework. As more and more apps switch to these proprietary APIs, they become less functional (or break entirely) on devices without the Play Store.

Four years ago, Ars Technica wrote a detailed analysis of using Android without all the proprietary Google software. It wasn't a great experience, as you can probably guess. But plenty can change in four years, so is the situation any better in 2018? That's what I wanted to find out.

Open Hardware: Open-source Circuit Simulation and Open-Source Turbomolecular Pump Controller

Filed under
Hardware
OSS
  • Open-source Circuit Simulation

    For simple circuits, it’s easy enough to grab a breadboard and start putting it together. Breadboards make it easy to check your circuit for mistakes before soldering together a finished product. But if you have a more complicated circuit, or if you need to do response modeling or other math on your design before you start building, you’ll need circuit simulation software.

    While it’s easy to get a trial version of something like OrCAD PSpice, this software doesn’t have all of the features available unless you’re willing to pony up some cash. Luckily, there’s a fully featured free and open source circuit simulation software called Qucs (Quite Universal Circuit Simulator), released under the GPL, that offers a decent alternative to other paid circuit simulators. Qucs runs its own software separate from SPICE since SPICE isn’t licensed for reuse.

  • An Open-Source Turbomolecular Pump Controller

    It’s not every project write-up that opens with a sentence like “I had this TURBOVAC 50 turbomolecular pump laying around…”, but then again not every write-up comes from someone with a lab as stuffed full of goodies as that of [Niklas Fauth]. His pump had an expired controller board, so he’s created an open-source controller of his own centred upon an STM32. Intriguingly he mentions its potential use as “I want to do more stuff with sputtering and Ion implantation in the future“, as one does of course.

    So given that probably not many Hackaday readers have a turbomolecular pump lying around but quite a few of you will find the subject interesting, what does this project do? Sadly it’s a little more mundane than the pump itself, since a turbomolecular pump is a highly specialised multi-stage turbine, this is a 3-phase motor controller with analogue speed feedback taken from the voltage across a couple of the motor phases. For this reason he makes the point that it’s a fork of his hoverboard motor controller software, the fruits of which we’ve shown you in the past. There isn’t a cut-out timer should the motor not reach full speed in a safe time, but he provides advice as to where to look in the code should that be necessary.

“We believe that the fundamental limit in technology is not its size or its cost or its speed,” writes Leap Motion, “but how we interact with it.”

This statement demonstrates the fresh perspective that companies like Leap Motion have been bringing to the commercial 3D tech industry. In fact, in the past year or two, we’ve started to feel a sea change as even the most entrenched, traditional manufacturers in the commercial 3D space have taken a hard turn toward simplicity of operation and sheer usability.

    So the past month or two? The Quarterly results cycle came in.

I'll come and do the full math later of the quarterly data. That race is no longer in any way interesting.

    But two Top 10 smartphone brands ARE in the news. One who is facing imminent death and the other who is making a miraculous return-from-dead. So imminent death and current Top 10 brand first. ZTE. The Trump administration has put a massive squeeze on ZTE and the company is in serious trouble of imminent collapse. Then bizarrely, Trump reversed course and felt he needed to protect CHINESE employment (???) and after yet another typical Trump-mess, we now are at a Never-Neverland where Trump's own party Republicans are revolting against their President and well, ZTE may end up a casualty of this mess. We'll keep an eye on it.
