Gadgets

The “BB.Suit,” a wearable wireless router garment prototype created by Dutch design house By Borre, runs OpenWRT Linux on a TP-Link router board.

Last month at South-by-Southwest (SXSW) in Austin, Texas, Dutch fashion designer Borre Akkersdijk unveiled his wearable computer called the BB.Suit. While most wearables are eye- or wrist-wear, the BB.Suit is an actual onesie garment with electronic circuitry woven in, including Bluetooth, GPS, NFC, and a WiFi access point.

When LG acquired the WebOS project from HP early last year, it was a stripped down Linux-based mobile operating system hardly fit to run on any hardware. Then in January, less than a year later, LG debuted its new WebOS smart TVs at the Consumer Electronics Show in Las Vegas. And until the first WebOS TVs hit retail shelves earlier this month the team was working around the clock for the release.

Fon has launched a Kickstarter project for a Linux-based “Gramofon” device that streams music from multiple mobile devices, and also acts as a WiFi hotspot.

With 26 days to go, Gramofon has yet to reach the halfway mark in funding toward its ambitious $250,000 Kickstarter goal. Fon plans to ship its first 6,500 units in July no matter what, but if the project is funded, it will expand its distribution, with later delivery dates. The Gramofon is now available for $30 (black) or $40 (white), with prices eventually rising to $50 and $60, respectively.

Ubuntu 14.04 will power “first commercially available Ubuntu tablets”

Gadgets

Canonical eventually wants to create a single operating system that can be installed across desktops, phones, and tablets, with a different interface presented on each device. That convergence hasn't been completed yet, so with 14.04 (codenamed "Trusty Tahr") there will be separate downloads for the mobile editions. "Full convergence means that the same code for operating systems and applications will be running on all types of devices, from phones to tablets to desktops, and even both smaller and larger devices," Ubuntu Engineering VP Rick Spencer told Ars in an e-mail. "Convergence is still a work in progress, and we will continue to move the code to the desktop as it is ready in each release."

I suspect we're in the very early days of gaming on the Fire TV. Amazon has gotten the Fire TV to market ahead of an Apple TV or Android TV that offers games, and we'll most likely see the game controller and the overall gaming experience get even better in future releases of the Fire TV.

Samsung's first attempt at putting together an advanced smartwatch based on Android, the Galaxy Gear, met with a very rough reception at the tail end of last year, and the company quickly switched to its own Tizen software for the Gear 2 and Gear 2 Neo. In emailed comments to The Verge, Samsung has confirmed Yoon's timeline of a 2014 release for its new smartwatch and clarified that it will indeed be using Android Wear. Together with the Gear Fit, which runs its own custom software, Samsung will soon be supporting three different operating systems for its wearable devices.

  • Ingo Juergensmann: Migrating from Drupal to WordPress

    If you can read this on planet.debian.org then migrating my blog from Drupal to WordPress was successful and the feed has been successfully changed by the Debian Planet Maintainers (thanks!). I’ve been a long term Drupal user. I think I started to use Drupal since it was included in Debian. At some point Drupal was removed from Debian and I started to use Serendipity instead. Later Drupal was included in Debian again and I moved back to Drupal. I think this must have been around Drupal 4 or Drupal 5. No idea. I even became active in the Drupal community and went to one of the first Drupal barcamps in Germany, namely in Cologne. This was shortly before Dries Buytaert started a business off of Drupal and went to the USA. I met with many devs of Drupal in Cologne and enjoyed the community and started with others a local Drupal User Group in Rostock. [...] So, after all the years my Drupal journey will come to an end. It was a long time with you. Sometimes joyful, sometimes painful. I wish you all the best, Drupal!

  • Red Kubes Container Platform Flies Open Source Flag

    Red Kubes, a Dutch-based startup, open sourced a free community edition of its Otomi Container Platform in a bid to remedy the ongoing complexity surrounding Kubernetes configurations. The scalability, agility, and speed-to-market advantages that Kubernetes offers have been handsome enough to capture a growing share of the enterprise market, but this very strength can become an Achilles heel for container deployments. In this sense, it’s far too easy – and common – to create thousands or even tens of thousands of containers across applications. Not only does this create an operational money pit, but management becomes a herculean feat to any container newbie.

  • Shots fired in disputes over OSS-as-a-Service

    Cloud services are the great disruptor of both IT organizations and vendors, and wrapping open source software around a service is the latest flashpoint. The open source development model has proven to be an incredible incubator of innovative software by democratizing and distributing the conception, design, implementation and debugging of new titles, advantages that were thoroughly explored more than two decades ago in the book, The Cathedral and the Bazaar. Although open source has since been adopted, encouraged and sponsored by every major software company, its origins were decidedly non-commercial with utopian overtones of liberating code from the tyranny of proprietary shackles. The earliest open source projects, notably Gnu Emacs and other tools from the Gnu Project, embraced this idealistic ethos with a restrictive, comprehensive license, GPL, that applies to derivative work using the code.

  • ROC and Precision-Recall curves - How do they compare?

    Both curves offer two useful information: how to choose the positive class prediction threshold and what is the overall performance of the classification model. The former is determined by selecting the threshold which yield the best tradeoff, in adequation with the prediction task and operational needs. The latter is done by measuring the area under the curves which informs about how good the model is, because by measuring the area under the curves, one computes the overall probability that a sample from the negative class has a lower probability than a sample from the positive class. With scikit-learn, the values can be computed either by using the roc_auc attribute of the object returned by plot_roc_curve() or by calling roc_auc_score() directly for ROC curves and by using the average_precision attribute of the object returned by plot_precision_recall_curve() or by calling average_precision_score() directly for PR curves.

    Some time ago, I wanted to give a blackboard-style look to a typeset equation. I started playing around with the GNU Image Manipulation Program (GIMP) and was satisfied with the result. The problem was that I had to perform several actions on the image, I wanted to use this style again, and I did not want to repeat the steps for all the images. Besides, I was sure that I would forget them in no time.

Open Hardware: Raspberry Pi, Arduino, Thomas Petazzoni (Bootlin) on Training

  • Qsync fixed on the Pi4 and FF compiled

    The Raspberry Pi4 does not have a hardware battery-backed clock, so relies on getting the date and time from an Internet time server. In EasyOS, Qsync is the utility that does that. At first bootup, QuickSetup has a checkbox to enable getting time from the Internet, which will launch Qsync. At first bootup on the Pi4, if you are going to connect to Internet via wifi, not ethernet, then there won't be an immediate Internet access. No problem, Qsync will run once the Internet connection is established. Qsync will run just once at bootup and after Internet connection. That's fine, but I couldn't understand why it would suddenly stop working. Then discovered that /etc/init.d/qsync was getting its executable-flag cleared.

Exelbierd spoke to Anderson to give an insider's perspective on Red Hat's effective termination of CentOS Linux in December, in which the open source giant announced CentOS Linux was to be deprecated immediately—with security upgrades to CentOS Linux 8 ending later in 2021 rather than the 2029 end of support date CentOS users expected.
