  • Backplane Systems Technology Presents Neousys’s IGT-22-DEV Industrial-grade IoT gateway Development Kit

    IGT-22-DEV provides a ready-for-use software environment featuring Debian Buster, Docker CE, Node-RED, Python3, GCC, and IoT platform agent configured with sensors and cloud connection. With minimum provisioning on the IoT platform, a web-based dashboard becomes available and can be accessed on a desktop computer, tablet, or mobile phone, wherever you may be. IGT series supports various programming languages, such as Python and GCC. On top of that, IGT-22-DEV has Node-RED pre-installed for intuitive graphical and local logic control of the built-in DO, allowing prompt responses. Unlike the standard IGT-22, the USB port of IGT-22-DEV is specifically set to OTG mode to provide serial and LAN functions over USB, so you can choose to connect to IGT-22-DEV with a USB cable.

  • Top 10 IoT Boards for Development and Prototyping in 2021

    This is one of the popular IoT Boards based on IoT Technology. The newest version of the low-cost Raspberry Pi computer is the all-new Raspberry Pi 4 Model B. This electronic board, which is the size of a credit card, has several enhancements. For starters, the power connector is USB-C, which may accommodate an additional 500mA of current, providing 1.2A for downstream USB devices. A pair of type-D (micro) HDMI connections have been installed instead of the type-A (full-size) HDMI connectors, allowing for dual display output within the existing board footprint. In Raspberry Pi 4, the Gigabit Ethernet magjack is now on the top right of the board, rather than the bottom right. It has a new operating system based on Debian 10 Buster, which will be released soon. The user interface has been modified, and new programs such as the Chromium 74 web browser have been included. Additionally, the Mesa “V3D” driver has replaced the legacy graphics driver stack used on previous models, allowing for the removal of nearly half of the platform’s closed-source code, as well as the ability to run 3D applications in a window under X, OpenGL-accelerated web browsing, and desktop composition.

    The NanoPi NEO Plus2 is a FriendlyElec-developed all-winner-based ARM board that is less than half the size of the Raspberry Pi. But that doesn’t make it any less capable in terms of storage and performance. Its operating system is Ubuntu Core 16.04, a strong Linux distro. It has a 64-bit quad-core Allwinner A53 SoC with Hexa-core Mali450 GPU, 1GB DDR3 RAM, 8GB eMMC storage, Wi-Fi, 4.0 dual-mode Bluetooth, and 1 MicroSD slot, 10/100/1000M Ethernet based on RTL8211E-VB-CG. In comparison to the Raspberry Pi, the NanoPi NEO Plus2 has gigabit Ethernet, 8 gigabytes of eMMC storage, and two USB ports. It is powered by a micro-USB port and, despite its little size, offers expandable memory owing to a microSD card. It also has additional benefits, such as low cost, fast speed, and high-performance computation.

  • Break point: Prometheus, JFrog, GDB, Boundary, Serverless Framework, Eclipse, Delphi, Kubermatic, and DataSpell

    The team behind monitoring system Prometheus has pushed version 2.30 into the wild, and with it some improvements to the scrape functionality. Amongst other things users can now adjust the scrape timestamp tolerance to save TSDB disk space in cases where a higher ms difference isn’t a problem. They also have access to an experimental way of configuring a scrape interval and timeout through relabeling, and new metrics behind the extra-scrape-metrics flag that expose the per-target scrape sample_limit value and scrape_timeout_seconds.

Pumpkins, markets, and one bad Apple

Imagine your local farmers market: every Saturday the whole town comes together to purchase fresh and homemade goods, enjoy the entertainment, and find that there is always something for everyone. Whatever you need, you can find it here, and anyone can sign up to have their own little stand. It is a wonderful place, or so it seems. Now, imagine starting out as a pumpkin farmer, and you want to sell your pumpkins at this market. The market owner asks 30% of every pumpkin that you sell. It's steep, but the market owner -- we'll call him Mr. Apple -- owns all the markets in your area, so you have little choice. Let's continue this analogy and imagine that, since it is a little hard for you to make ends meet, you decide to tell your customers that they can come visit you at your farm to purchase pumpkins. Mr. Apple overhears and shuts your stand down. You explain that your business cannot be profitable this way, but the grumpy market owner says that you can either comply or find another place. At the end of your rope, you look for information about starting your own farmers market, but it seems Mr. Apple owns every building in town. In the midst of Apple announcing its new products, attention is drawn away from its ongoing battle to maintain its subjugation over users globally. The Netherlands’ Authority for Consumers and Markets (ACM) last month informed the U.S. technology giant of its decision that the rules around the in-app payment system are anticompetitive, making it the first antitrust regulator to conclude that the company has abused market power in the App Store. And while Apple is appealing this verdict, the European Union is charging the company with another antitrust claim concerning the App Store. Read more

  • How to Upgrade to Ubuntu 21.10 - OMG! Ubuntu!

    If the glowing reviews for the Ubuntu 21.10 release have you intrigued, here’s how to upgrade to Ubuntu 21.10 from an earlier version. Fair warning: this tutorial is super straightforward (the benefits of upgrading after a stable release, rather than a little bit before). Meaning no, you don’t need to be a Linux guru to get going! There are plenty of good reasons to upgrade from Ubuntu 21.04 to Ubuntu 21.10, such as benefiting from a newer Linux kernel, enjoying a new GNOME desktop, sampling the new Yaru Light theme, and getting to go hands-on with an able assortment of updated apps.

Development version: GIMP 2.99.8 Released

GIMP 2.99.8 is our new development version, once again coming with a huge set of improvements. Read more Some early coverage:

  • GIMP 2.99.8 Released with Clone Tool Tweaks, Support for Windows Ink

    A new development version of GIMP is available to download and it carries some interesting new features. While this isn’t a new stable release — GIMP 2.10.28 is the most recent stable release (and the version you’ll find in Ubuntu 21.10’s archives) — the release of GIMP 2.99.8 is yet another brick in the road to the long-fabled GIMP 3.0 release. And it’s a fairly substantial brick, at that.

  • GIMP 2.99.8 Released As Another Step Toward The Long Overdue GIMP 3.0

    GIMP 3.0 as the GTK3 port of this open-source Adobe Photoshop alternative has been talked about for nearly a decade now and the work remains ongoing. However, out today is GIMP 2.99.8 as the newest development snapshot.

Mozilla: Six-Year Moziversary, Thomas Park/Codepip, and Weak Response to Critics of Firefox Spyware

  • Chris H-C: Six-Year Moziversary

    I’ve been working at Mozilla for six years today. Wow. Okay, so what’s happened… I’ve been promoted to Staff Software Engineer. Georg and I’d been working on that before he left, and then, well *gestures at everything*. This means it doesn’t really _feel_ that different to be a Staff instead of a Senior since I’ve been operating at the latter level for over a year now, but the it’s nice that the title caught up. Next stop: well, actually, I think Staff’s a good place for now. Firefox On Glean did indeed take my entire 2020 at work, and did complete on time and on budget. Glean is now available to be used in Firefox Desktop.

  • Mark Surman: Exploring better data stewardship at Mozilla [Ed: Mozilla fails to admit that spying on Firefox users is wrong; now it's misframing the criticism and responds to a straw man]

    Over the last few years, Mozilla has increasingly turned its attention to the question of ‘how we build more trustworthy AI?’ Data is at the core of this question. Who has our data? What are they using it for? Do they have my interests in mind, or only their own? Do I trust them? We decided earlier this year that ‘better data stewardship’ should be one of the three big areas of focus for our trustworthy AI work. One part of this focus is supporting the growing field of people working on data trusts, data cooperatives and other efforts to build trust and shift power dynamics around data. In partnership with Luminate and Siegel, we launched the Mozilla Data Futures Lab in March as a way to drive this part of the work.
