Embedded Linux Conference & IoT Summit 2018 Schedule

The Embedded Linux Conference 2018 and the OpenIoT Summit 2018 will jointly take place next month, on March 12 – 14, 2018 in Portland, Oregon, USA. The former is a “vendor-neutral technical conference for companies and developers using Linux in embedded products”, while the latter is a “technical conference for the developers and architects working on industrial IoT”. The Linux Foundation has already published the schedule, and it’s always useful to learn what will be discussed about even for people who won’t attend. With that in mind, here’s my own virtual schedule with some of the talks I find interesting / relevant to this blog. Monday, March 12 10:50 – 11:40 – Progress in the Embedded GPU Ecosystem by Robert Foss, Collabora Ltd. Ten years ago no one would have expected the embedded GPU ecosystem in Linux to be what it is now. Today, a large number of GPUs have […]

Monitor Network Traffic per Process with Nethogs

Yesterday I wrote about using 3G on Raspberry Pi board, and one of the commenter mentioned higher traffic than expected when connecting to 3G to just send a few bytes before disconnecting. One of the reasons are the extra data needed if you transmit data over a secure connection, for example establishing a PPP connection, connect to the board over SSH, and disconnect, results in the transmission & reception of a few kilobytes on my board:

Connect time 1.9 minutes. 
Sent 5815 bytes, received 6972 bytes.

1 2	Connect time 1.9 minutes. Sent 5815 bytes, received 6972 bytes.

But if you get much more traffic than that, you may want to investigate if another package may transfer data when it detects the connection is up. To analyze traffic, tcpdump and Wireshark are good options, especially if you want to look into the packets data, however such tools do not tell you which process is sending or receiving the data. So I searched whether I could find a program that would do […]

Open Source Software Releases – VLC 3.0 and Android-x86 7.1-r1

Two completely unrelated open source projects have released a stable version of their software this week, but instead of writing a post for each I’ll write about them in a single post. VLC 3.0 Vetinari VLC developers have just released version 3.0 – codenamed Vetinari – of the popular media player with new features such as ChromeCast support, and 8K video playback. Other highlights from the release include: Hardware decoding enabled by default to get 4K and 8K playback 10-bit and HDR support (only on Windows 10 Fall Creators Update for now) 360 video and 3D audio, up to Ambisoncics 3rd order Allows audio passthrough for HD audio codecs Can play Blu-Ray Java menus: BD-J Browsing of local network drives and NAS VLC 3.0 is also the first major version to be released for all platforms at the same time, and you can download VLC 3.0 for Windows, Mac OS […]

Vorke V1 Plus Celeron J3455 Mini PC Review with Windows and Ubuntu

Most Intel based mini PCs use processors classified as ‘Mobile’ as these have lower thermal design power (TDP) ratings which is the maximum amount of heat generated by the processor: However, the new Vorke V1 Plus has incorporated a ‘Desktop’ processor namely the Intel Celeron J3455. On paper this processor looks like it should perform similar to the Intel Pentium N4200 processor but with a tradeoff between being a cheaper processor to purchase but more expensive to run due to the increased power requirements. Geekbuying provided a Vorke V1 Plus for review so let’s start by taking a look at the physical characteristics. The device comes in a plain box and was supplied with the ‘right AC Adapter’ for my country. The first observation is that it is quite a large device. At just over 6” square (153mm) and nearly 1.5” tall (38mm) it is the biggest mini PC I’ve […]

Ubuntu 18.04 LTS Minimal Image Gets Even Smaller (30MB Compressed)

Sometimes you want to get the smallest image you can get, either because your storage device has limited capacity, you may want a faster boot, oe because you can. In the past, I’ve covered minimal firmware images for Raspberry Pi using Raspbian or the Yocto Project, as well as SliTaz or more recently a minimal Ubuntu 16.04 for ODROID C2/C1+ boards. Minimal images are also popular for containers like docker or LXD. Canonical has released Ubuntu minimal images for several years, and Dustin Kirklan blogged about Ubuntu 18.04 LTS mini images a few days ago, showing the good progress made over Ubuntu 14.04 and 18.04 “Bionic Beaver”, and asking for feedback. The charts above shows the minimal image went from around 62.78 MB (compressed) and 179.67 MB (uncompressed) for Ubuntu 14.04 LTS down to 29.65 MB (compressed) and 77.5 MB (uncompressed). That’s the number of AMD64 images, but ARM64 Ubuntu […]

Getting Started with IkaScope WiFi Pen-Oscilloscope, and ScanaQuad SQ50 USB Logic Analyzer & Signal Generator

A couple of weeks ago, I received IkaScope WS200 pen-like WiFi oscilloscope, as well as ScanaQuad SQ50 USB logic analyzer & signal generator, and I’ve already checked out the hardware both both in a aforelinked unboxing post. I had also very shortly tried IkaScope with GOLE 10 mini PC, but just to showcase potential use case for a Windows 10 mini PC with an inclined touchscreen display. But at the time I did not really a proper measurement, as it was more to test the mini PC than the oscilloscope itself. I’ve now had time to test IkaScope desktop program and mobile app in respectively Ubuntu 16.04 and Android 8.0.0, as well as ScanaStudio for ScanaQuad USB device using Ubuntu 16.04 only, since there’s no mobile version of the program. While I’ll focus on Ubuntu and Android, most of the instructions will be valid for Window 10 and Mac OS X […]
