  • Debugging Tools

    That’s three strands (red, white, black) from a USB-to-serial converter, soldered on to a 3-pole screw-tightened connector. Clamped into that are the serial lines (red, green and blue) which were originally crimped straight to the lines. After a few months of use, the crimping failed and the red cable (RX) broke off.

    So I had to fix it, and in the process decided to make it more sturdy, more ugly, but also easier to use.

  • TP-Link Smart Wi-Fi Plug with Energy Monitoring Review

    Opening up the box reveals both plugs sitting in a plastic tray. A quick start guide, tech support contact information, and a copy of the GNU General Public License were found on top of the plugs. Following the quick start guide proved to be very straightforward.

  • Reading Buttons from a Raspberry Pi

    When you attach hardware buttons to a Raspberry Pi's GPIO pin, reading the button's value at any given instant is easy with GPIO.input(). But what if you want to watch for button changes? And how do you do that from a GUI program where the main loop is buried in some library?

  • Rooting Android Just Isn’t Worth It Anymore

    Since Android is based on Linux and uses a Linux kernel, “rooting” effectively means allowing access to root permissions in Linux. It’s really that simple—these permissions aren’t granted to normal users and apps, so you have to do some special work to gain them.

  • What’s the Difference Between Android One and Android Go?

    In 2014, Google announced a lineup of low-cost, low-spec phones called Android One. In 2017, they announced Android Go, specifically designed for low-cost, low-spec phones. So…what’s the difference?

PC desktop build, Intel, spectre issues etc.

Security

Apart from the initial system bought, most of my systems when being changed were in the INR 20-25k/- budget including all and any accessories I bought later.

The only real expensive parts I purchased have been external hdd ( 1 TB WD passport) and then a Viewsonic 17″ LCD which together sent me back by around INR 10k/- but both seem to give me adequate performance (both have outlived the warranty years) with the monitor being used almost 24×7 over 6 years or so, of course over GNU/Linux specifically Debian. Both have been extremely well value for the money.

As I had been exposed to both the motherboards I had been following those and other motherboards as well. What was and has been interesting to observe what Asus did later was to focus more on the high-end gaming market while Gigabyte continued to dilute it energy both in the mid and high-end motherboards.

Hardware

Digilent and RS Components have launched a $15, Python supported “Pmod HAT Adapter” for the Raspberry Pi that can connect up to three Digilent Pmod peripheral modules at a time while also extending the 40-pin adapter.

Digilent has joined with distributor RS Components to co-launch a $15 DesignSpark Raspberry Pi Pmod HAT Adapter board that brings Digilent’s Pmod peripheral boards to the Raspberry Pi. The 65 x 56.5mm HAT compliant board offers three 2×6-pin Pmod ports with support for I2C, SPI, UART and GPIO interfaces. The Raspberry Pi’s 40-pin adapter is extended to make full use of the SBC’s interfaces.

First Impressions: Asus Tinkerboard and Docker

Filed under
Linux
Hardware

The board's standard OS is TinkerOS - a Linux variant of Debian 9. I've also read that Android is available but that doesn't interest us here. While Android may use forms of containerisation under the hood it doesn't mix with Docker containers.

Rather than trying TinkerOS I flashed Armbian's release of Ubuntu 16.04.03. The stable build on the download page contains a full desktop, but if you want to run the board headless (like I do) then you can find a smaller image on the "other downloads" link.

I initially used the stable image but had to swap to the nightly build due to a missing kernel module for Kubernetes networking. Having looked this up on Google I found the nightly build contained the fix to turn on the missing module.

  • Librem 5 Phone Progress Report – The First of Many More to Come!

    First, let me apologize for the silence. It was not because we went into hibernation for the winter, but because we were so busy in the initial preparation and planning of a totally new product while orienting an entirely new development team. Since we are more settled into place now, we want to change this pattern of silence and provide regular updates. Purism will be giving weekly news update posts every Tuesday, rotating between progress on phone development from a technology viewpoint (the hardware, kernel, OS, etc.) and an art of design viewpoint (UI/UX from GNOME/GTK to KDE/Plasma). To kickoff this new update process, this post will discus the technological progress of the Librem 5 since November of 2017.

  • Purism Eyeing The i.MX8M For The Librem 5 Smartphone, Issues First Status Update

    If you have been curious about the state of Purism's Librem 5 smartphone project since its successful crowdfunding last year and expedited plans to begin shipping this Linux smartphone in early 2019, the company has issued their first status update.

Yocto-on-i.MX6UL gateway serves up I2C and SPI on a DB9 port

Hardware

Axiomtek’s compact “IFB125” DIN-rail IoT gateway runs Yocto Linux on an i.MX6 UL SoC with dual LANs, mini-PCIe expansion, extended temperature and vibration resistance, COM and USB ports, and a DB9 port that supports both SPI and I2C.

Axiomtek has released a minor variation on its IFB122 IoT gateway. Like the IDB122, the new IFB125 runs Yocto Project code with Linux 3.14.52 on NXP’s 528MHz Cortex-A7 based i.MX6 UltraLight (UL) SoC. The headless gateway is designed for remote control and remote monitoring management applications such as unmanned control room, industrial automation, automatic parking lot, and traffic cabinets.

Mozilla Firefox 58

  • Latest Firefox Quantum release available with faster, always-on privacy with opt-in Tracking Protection and new features
    We accept things in the online world that we wouldn’t accept in the physical one. For instance, how would you feel if you popped your head in a store and that store now had the ability to keep sending you flyers even if you didn’t buy anything? Online, we often visit sites that track us, but it isn’t clear when this is happening or how the information is being used. Adding insult to injury, this often invisible tracking actually slows down web pages.
