One of my favorite manufacturers of high-quality, reasonably priced, Linux-friendly audio equipment is Schiit Audio. I recently noticed they have a new gizmo at the low end of their product line, the Fulla 2, and I decided to purchase it. Basically, this is a DAC and headphone amplifier all in one unit, meaning it covers Step 2 and a part of Step 3 as I mentioned previously, and also adds some interesting additional features. I start with the DAC+headphones part. To get it going, you plug the USB cable into a laptop's USB2 or USB3 port and the other end into the Fulla 2's "USB Power and Data Input" port, set up your music player to send output to that device, plug in your headphones, and away you go.
The example uses a Raspberry Pi connected to an evaluation board. A cheap Sigrok-based logic analyzer let him troubleshoot and debug. If you think FPGA development is expensive, think again. The board used here is well under $50 and the software is free. An iCEStick is even cheaper, and would probably work here, too. You are likely to have the other bits, but even if you need to buy a Pi and the logic analyzer, the whole thing is way under $100.
Great news for our photography lovers as the Candy Camera app has finally hit the Tizen Store. I say finally, as this is one of the most requested camera apps for the Tizen platform. It has already been a success on Android and iOS for selfies and now JP Brothers Inc. have made it compatible with Tizen Smartphones. Candy Camera has many great features and below I will describe some highlighted features-
The NanoPi K2 is like an Odroid-C2 with WiFi and BT 4.0. The $40, open spec SBC offers a quad- A53, 1.5GHz Amlogic S905, 4x USB, GbE, and a 40-pin bus.
Rampant imitation is making it easier to write up these new hacker board releases. Just cut and paste an existing feature table, add and subtract a few features, and you’re done. In the case of the FriendlyElec (FriendlyARM) NanoPi K2, it’s even easier than usual. The board has the same processor, 85 x 56mm footprint, and almost an identical feature set and layout as Hardkernel’s Odroid-C2, which means it is also very similar to the Raspberry Pi 3. The NanoPi K2 and Odroid-C2 even opened with the same $40 price, although the latter now sells for $46.
Over the years, there has been a lot of mixed information as to what Linux cloud servers actually mean. This article aims to clear the air once and for all with a concise explanation while providing you with a list of Linux cloud server resources from which you can investigate for yourselves.
The Raspberry Pi computer can be used in all kinds of settings and for a variety of purposes. It obviously has a place in education for helping students with learning programming and maker skills in the classroom and the hackspace, and it has plenty of industrial applications in the workplace and in factories. I'm going to introduce five projects you might want to build in your own home.
I recently wrote an article talking about where the Ubuntu 17.04 is heading. Now Ubuntu 17.04 'Zesty Zapus' is released. You can download and install it to taste things newly presented. Though, there are not major changes but there are. So let's get started and see what's new in Ubuntu 17.04 'Zesty Zapus'.
OpenShot is a free and open source video editing application both for enthusiasts and professionals alike... uh... but don’t expect it to be better than lightworks or those adobe suit (video editing) counter-parts. Anyway, it’ll surprise you with many features and yes the integration with blender gives you the power of 3D on your hands!
Aetina’s Nano-ITX “ACE-N620” carrier board for Nvidia’s Linux-driven Jetson TX2 and TX1 modules offers optional mini-PCIe expansion cards from Innodisk.
Aetina’s Nano-ITX form-factor ACE-N620 carrier board offers some more development options for Nvidia’s Jetson TX2 COM, as well as its earlier, pin-compatible Jetson TX1. Already, Connect Tech has released three carrier boards for the Jetson TX2 and TX1, and Auvidea is prepping a J140 carrier for the Nvidia Tegra-based modules.
Gravitational, maker of a software-as-a-service support system built with Kubernetes, has released the latest open source iteration of a key part of that system.
Teleport, an SSH server that provides support teams with a simpler way to remotely manage server clusters, is an example of Google's Go language being used to devise safer but still performant replacements for critical infrastructure.
The Linux Foundation, the nonprofit advancing professional open source management for mass collaboration, today announces that the API Strategy & Practice Conference has become a Linux Foundation event and will be jointly produced with the Open API Initiative (OAI), a Linux Foundation project. Linux Foundation events are where the world’s leading technologists meet, collaborate and innovate. APIStrat 2017 will take place October 31 – November 2 in Portland, OR.
At last year’s Embedded Linux Conference Europe, Sony’s Tim Bird warned that the stalled progress in reducing Linux kernel size meant that Linux was ceding the huge market in IoT edge nodes to real-time operating systems (RTOSes). At this February’s ELC North America event, another figure who has long been at the center of the ELC scene -- Free Electron’s Michael Opdenacker -- summed up the latest kernel shrinkage schemes as well as future possibilities. Due perhaps to Tim Bird’s exhortations, ELC 2017 had several presentations on reducing footprint, including Rob Landley’s Tutorial: Building the Simplest Possible Linux System.
Like Bird, Opdenacker bemoaned the lack of progress, but said there are plenty of ways for embedded Linux developers to reduce footprint. These range from using newer technologies such as musl, toybox, and Clang to revisiting other approaches that developers sometimes overlook.
In his talk, Opdenacker explained that the traditional motivator for shrinking the kernel was to speed boot time or copy a Linux image from low-capacity storage. In today’s IoT world, this has been joined with meeting the requirement for very small endpoints with limited resources. These aren’t the only reasons, however. “Some want to run Linux as a bootloader so they don’t have to re-create bootloader drivers, and some want to run to the whole system in internal RAM or cache,” said Opdenacker. “A small kernel can also reduce the attack surface to improve security.”
If we've learned anything in the technology business in the last 25 years, it would be to never underestimate the Linux kernel. Why, then, have so many networking companies been so eager to bypass the Linux kernel -- or more specifically, the Linux kernel networking stack? What could be so wrong with the networking packet arteries in the Linux kernel that motivates so many of us to bypass them?
There are two main reasons. First, the kernel networking stack is too slow -- and the problem is only getting worse with the adoption of higher speed networking in servers and switches (10GbE, 25GbE, and 40GbE today, and rising to 50GbE and 100GbE in the near future). Second, handling networking outside the kernel allows for plugging in new technology without the need to change core Linux kernel code.
Greg Kroah-Hartman announced today, April 12, 2017, the release and immediate availability of three new kernel updates, namely Linux 4.10.10, 4.9.22 LTS, and 4.4.61 LTS.
Coming only four days after their previous maintenance updates, the Linux 4.10.10, Linux 4.9.22 LTS, and Linux 4.4.61 LTS kernels are here with a set of new improvements for users of Linux-based operating systems. Despite the short development time, it looks like Linux kernel 4.10.10 changes a total of 99 files, with 1208 insertions and 604 deletions, and Linux kernel 4.9.22 LTS changes 134 files, with 1944 insertions and 784 deletions.
ntel's Clear Linux distribution has switched from using the ACPI CPUFreq scaling driver for recent generations of Intel hardware to now using the P-State CPU frequency scaling driver.
Kent Overstreet continues developing Bcachefs as what he hopes will be a next-generation Linux file-system code that's originally derived -- but now distantly removed -- from the Bcache code-base.
Last month we reported on Bcachefs rolling out a new on-disk format with encryption and better multi-device support while Kent Overstreet has issued a new post with the latest happenings. Bcachefs was launched in 2015, for those that don't remember, with hopes of EXT4/XFS-like speed but with Btrfs/ZFS-like features.
Elie Tournier, the GSoC student developer who last year worked via GSoC on "soft" FP64 double-precision support for older GPUs lacking the hardware capabilities, has posted patches wiring up his soft implementation for Intel "Gen 6" (Sandy Bridge) graphics thereby allowing ARB_gpu_shader_fp64 support.
The folks behind StreamComputing BV are looking to strengthen the OpenCL compute ecosystem by improving the documentation and code samples as well as better overviews for those wishing to learn this Khronos compute standard.
