  • 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.

Linux
Hardware

Good news for earthbound Pi-tinkerers hoping to get their code into orbit: a follow-up to 2015's Astro Pi is due to head to the International Space Station (ISS) this year.

Time has moved on a bit since the Principia mission of Tim Peake where the first units were installed aboard the orbiting outpost. While over 54,000 participants from 26 countries have since had code run on the hardware, the kit has fallen somewhat behind what is available on Earth.

To that end, some new units are due to be launched, replete with updated hardware. In this case, heading to orbit will be Raspberry Pi 4 Model B units with 8GB RAM, the Raspberry Pi High Quality Camera (a 12.3MP device) and the usual complement of gyroscope, accelerometer, magnetometer, humidity, temperature and pressure sensors for users to code against.

  • How a glitch in the Matrix led to apps potentially exposing encrypted chats

    The Matrix.org Foundation, which oversees the Matrix decentralized communication protocol, said on Monday multiple Matrix clients and libraries contain a vulnerability that can potentially be abused to expose encrypted messages.

    The organization said a blunder in an implementation of the Matrix key sharing scheme – designed to allow a user's newly logged-in device to obtain the keys to decrypt old messages – led to the creation of client code that fails to adequately verify device identity. As a result, an attacker could fetch a Matrix client user's keys.

    Specifically, a paragraph in Matrix E2EE (end-to-end encryption) Implementation Guide, which described the desired key handling routine, was followed in the creation of Matrix's original matrix-js-sdk code. According to the foundation, this SDK "did not sufficiently verify the identity of the device requesting the keyshare," and this oversight made its way into other libraries and Matrix chat clients.

  • How to use iPerf3 to test network bandwidth

    Admins must measure the throughput of their WAN links to ensure they are working properly. One way to do that is by using iPerf, the open source benchmarking utility. The latest version, iPerf3, is a complete rewrite of the code first developed by the National Laboratory for Applied Network Research in the 2000s.

    Like its predecessors, iPerf3 tests the bandwidth between any two networked computers to determine if the available bandwidth is large enough to support the transmission of an application.

    IPerf3 is built on a client-server model and measures maximum User Datagram Protocol, TCP and Stream Control Transmission Protocol throughput between client and server stations. It can also be used to measure LAN and wireless LAN throughput.

The distribution is available in two flavours, Minimal and with JWM as the default window manager. The Minimal edition is an 837MB download while the JWM edition is 1.3GB in size. I chose to download the JWM edition for x86_64 computers.

Booting from the provided ISO brings up a menu offering to start the distribution in Live, Persistent, or Run From RAM modes. This gives us some flexibility in how we wish to use the live media. I chose to take the default, plain live mode. The live session boots to a text console where we are shown login credentials for both the root user and a regular user account. Signing in as the regular user, oblive, automatically launches a graphical environment.

The JWM-powered desktop places a panel along the bottom of the screen. The panel holds an application menu, task switcher, and system tray. On the desktop we find icons for opening a README file and for launching the system installer. The README file is a short text file with login credentials, links to on-line resources, and tips for launching programs from within JWM.

Shortly after signing into the live desktop a network management window opens. This provides us with a utility for getting us on-line with minimal effort. The network manager window makes it straight forward to connect to wired and wireless networks.

Linux 5.15-rc2

Filed under
Linux

So I've spent a fair amount of this week trying to sort out all the
odd warnings, and I want to particularly thank Guenter Roeck for his
work on tracking where the build failures due to -Werror come from.

Is it done? No. But on the whole I'm feeling fairly good about this
all, even if it has meant that I've been looking at some really odd
and grotty code. Who knew I'd still worry about some odd EISA driver
on alpha, after all these years? A slight change of pace ;)

The most annoying thing is probably the "fix one odd corner case,
three others rear their ugly heads". But I remain convinced that it's
all for a good cause, and that we really do want to have a clean build
even for the crazy odd cases.

We'll get there.

Anyway, I hope this release will turn more normal soon - but the rc2
week tends to be fairly quiet for me, so the fact that I then ended up
looking at reports of odd warnings-turned-errors this week wasn't too
bad.

There's obviously other fixes in here too, only a small subset of the
shortlog below is due to the warning fixes, even if that's what I've
personally been most involved with.

Go test, and keep the reports coming,

  • SD Times news digest: Android for Cars App Library 1.1, MariaDB announces a technical preview of NoSQL listener capability, and Rezilion funding - SD Times

    MariaDB released the technical preview of the NoSQL listener capability to define a port and protocol pair that accept client connections to a service.

    “We’ve opened up a port on MaxScale to listen for traffic that contains NoSQL data that we then store and manage in a MariaDB database,” Rob Hedgpeth, Director, Developer Relations at MariaDB, wrote in a blog post.

    When the MongoDB client application issues MongoDB protocol commands, either directly or indirectly via the client library, they are transparently converted into the equivalent SQL and executed against the MariaDB backend. The MariaDB responses are then in turn converted into the format expected by the MongoDB client library and application.

  • All the changes between JDK 11 and the Java 17 LTS release

    If you were to look at the features in Java 17, the most recent long-term support (LTS) release from Oracle, you’d probably be disappointed. There’s only 14 JDK enhancement proposals (JEP) included in the release, and none of them are particularly exciting. In fact, some of the JEPs are downright depressing, such as the deprecation of the Applet API for removal or the removal of the experimental AOT and JIT compilers.

    There are no ‘big bang’ JDK releases anymore. In the past, there would be a highly anticipated feature such as Java modules or Lambda expressions that would delay a release until the feature was complete. The Java world doesn’t work like that anymore. Releases now happen every six months. If a feature is complete, it goes into the release. If not, it gets targeted to the next release. But a new release happens every six months, and feature enhancements happen incrementally over time. So if you want to know what’s new in the latest LTS release, you really need to look over the various changes that were made and enhancements that were added between Java 11 and 17. Starting with Java 12, here is a list of them:

  • The future of Rust

    Despite its name, the Rust programming language has never looked so shiny and new. Way back in 2016, Stack Overflow’s annual survey of developers crowned Rust the “most loved” programming language. They voted their love again in 2017, 2018, 2019, 2020, and 2021. Presumably, when 2022 rolls around, that devotion to Rust will persist.

    Whisker Menu is an alternate application launcher for Xfce. When you open it you are shown a list of applications you have marked as favorites. You can browse through all of your installed applications by clicking on the category buttons on the side. Top level categories make browsing fast, and simple to switch between. Additionally, Whisker Menu keeps a list of the last ten applications that you’ve launched from it.

    Favorites are easy to add and reorder. When browsing through your applications, right-click on any of them and select “Add to Favorites”. Simply drag and drop your favorites list to arrange them to suit your needs. You can remove them at any time from another right-click option.

    If you’re not sure exactly where a program is listed, instead of browsing through each category you can simply enter a search term. The search field is focused when opening the menu, so you can just start typing. Application descriptions as well as names are searched, which allows you to find a program by using a general word (such as “browser” to find all web browsers installed on your computer).

Spyware: KDE Plasma, like Gnome, the anti-FOSS eye-candy blackmail

Filed under
KDE

The terminology used by such corporations is very deceptive on its own. Spying on the user and collecting data without really his conscious consent, is just spying. Whether you call it telemetry, or user feedback, or kuserfeedback-1.0.0, it is still spying. The software that is written for spying is called spyware. ms-Windows users pay dearly to other spyware sellers to clean their machines from spyware. While you are at it, looking at the source, also take a look at Ksystemstats as well.

So what distributions promote and co-sign the safety of using free open software that are spyware?

Better ask which distributions DON’T and will come out saying it that they condemn such practices and the use of such software.

Why is this so important? Why is it that you, or anyone else, gave up on closed source non-free non-libre software to come to Linux or BSD, or Solaris, ot any unix?

Exactly! This crap doesn’t belong in linux or any computer. If you volunteer to provide your data or report a bug with your own intention and choice, that is different, than some sub-system in the background copying and feeding your data to some datacenter KDE/plasma has setup to do data-mining.

Alternatively someone can criticize us being superficial and hypocritical, because KDE has the decency to advertise they are officially doing this, while others are doing it secretly. We are not all knowing all catching of all problems and issues on FOSS, we report on what we find important.

  • The Best Ways to Know Which Process Listening on a Specified Port

    A port is a communication endpoint. At the software level, within an operating system, a port is a logical construct that identifies a specific process or a type of network service. A port is identified for each transport protocol and address combination by a 16-bit unsigned number, known as the port number. The most common transport protocols that use port numbers are the Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP).

    Also port is a logical entity that represents an endpoint of communication and is associated with a given process or service in an operating system. In previous articles, we explained how to find out the list of all open ports in Linux and how to check if remote ports are reachable using the Netcat command.

Astro Pi 2: New Raspberry Pi hardware with updated camera, sensors to head to the ISS this year

Good news for earthbound Pi-tinkerers hoping to get their code into orbit: a follow-up to 2015's Astro Pi is due to head to the International Space Station (ISS) this year. Time has moved on a bit since the Principia mission of Tim Peake where the first units were installed aboard the orbiting outpost. While over 54,000 participants from 26 countries have since had code run on the hardware, the kit has fallen somewhat behind what is available on Earth. To that end, some new units are due to be launched, replete with updated hardware. In this case, heading to orbit will be Raspberry Pi 4 Model B units with 8GB RAM, the Raspberry Pi High Quality Camera (a 12.3MP device) and the usual complement of gyroscope, accelerometer, magnetometer, humidity, temperature and pressure sensors for users to code against.
