  • 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?

In the early days of Android, co-founder Andy Rubin set the stage for the fledgling mobile operating system. Android’s mission was to create smarter mobile devices, ones that were more aware of their owner’s behavior and location.“If people are smart,” Rubin told Business Week in 2003, “that information starts getting aggregated into consumer products.” A decade and a half later, that goal has become a reality: Android-powered gadgets are in the hands of billions and are loaded with software shipped by Google, the world’s largest ad broker.Android Users: To Avoid Malware, Try the F-Droid App Store

US Sanctions Against Chinese Android Phones, LWN Report on Eelo

  • A new bill would ban the US government from using Huawei and ZTE phones

    US lawmakers have long worried about the security risks posed the alleged ties between Chinese companies Huawei and ZTE and the country’s government. To that end, Texas Representative Mike Conaway introduced a bill last week called Defending U.S. Government Communications Act, which aims to ban US government agencies from using phones and equipment from the companies.

    Conaway’s bill would prohibit the US government from purchasing and using “telecommunications equipment and/or services,” from Huawei and ZTE. In a statement on his site, he says that technology coming from the country poses a threat to national security, and that use of this equipment “would be inviting Chinese surveillance into all aspects of our lives,” and cites US Intelligence and counterintelligence officials who say that Huawei has shared information with state leaders, and that the its business in the US is growing, representing a further security risk.

  • U.S. lawmakers urge AT&T to cut commercial ties with Huawei - sources

    U.S. lawmakers are urging AT&T Inc, the No. 2 wireless carrier, to cut commercial ties to Chinese phone maker Huawei Technologies Co Ltd and oppose plans by telecom operator China Mobile Ltd to enter the U.S. market because of national security concerns, two congressional aides said.

    The warning comes after the administration of U.S. President Donald Trump took a harder line on policies initiated by his predecessor Barack Obama on issues ranging from Beijing’s role in restraining North Korea to Chinese efforts to acquire U.S. strategic industries.

    Earlier this month, AT&T was forced to scrap a plan to offer its customers Huawei [HWT.UL] handsets after some members of Congress lobbied against the idea with federal regulators, sources told Reuters.

  • Eelo seeks to make a privacy-focused phone

    A focus on privacy is a key feature being touted by a number of different projects these days—from KDE to Tails to Nextcloud. One of the biggest privacy leaks for most people is their phone, so it is no surprise that there are projects looking to address that as well. A new entrant in that category is eelo, which is a non-profit project aimed at producing not only a phone, but also a suite of web services. All of that could potentially replace the Google or Apple mothership, which tend to collect as much personal data as possible.

Linux

For those unfamiliar with intel-gpu-tools, it's a collection of tools for GNU/Linux distribution that allows the debugging the official Intel graphics driver for Intel GPUs. Tools include a GPU hang dumping program, performance microbenchmarks for regression testing the DRM, as well as a performance monitor.

The latest release, intel-gpu-tools 1.21, adds quite a bunch of changes, including automatic loading of DRM modules when opening a DRM device, much-improved GPU quiescing code to more thoroughly flush pending work and old data, as well as production support for the Meson build system while automake is still kept around.

The npm Bug

  • ​Show-stopping bug appears in npm Node.js package manager
    Are you a developer who uses npm as the package manager for your JavaScript or Node.js code? If so, do not -- I repeat do not -- upgrade to npm 5.7.0. Nothing good can come of it. As one user reported, "This destroyed 3 production servers after a single deploy!" So, what happened here? According to the npm GitHub bug report, "By running sudo npm under a non-root user (root users do not have the same effect), filesystem permissions are being heavily modified. For example, if I run sudo npm --help or sudo npm update -g, both commands cause my filesystem to change ownership of directories such as /etc, /usr, /boot, and other directories needed for running the system. It appears that the ownership is recursively changed to the user currently running npm."
  • Botched npm Update Crashes Linux Systems, Forces Users to Reinstall
    A bug in npm (Node Package Manager), the most widely used JavaScript package manager, will change ownership of crucial Linux system folders, such as /etc, /usr, /boot. Changing ownership of these files either crashes the system, various local apps, or prevents the system from booting, according to reports from users who installed npm v5.7.0. —the buggy npm update.

Windows 10 WSL vs. Linux Performance For Early 2018
