  • The Best Chromebooks to Buy In 2019

    Advancements in technology over the past few decades has been all about shrinking down computers. We’ve also seen manufacturers cramming as much power in them as humanly possible. This has led us to the creation of small form factor desktop PCs, portable yet powerful gaming laptops and even handhelds.

    Despite the fact that a faster computer is almost always appreciated, a lot of people don’t need all that power most of the time. Especially when responding to e-mails, or writing up text documents. In this scenario, a lot of people can get away with using a Chromebook every day.

    Chromebooks are different from your traditional Windows laptops. They run on Google’s own version of desktop OS, known as ChromOS. These affordable machines have especially gained popularity among students. This is mainly because of their workflow, most of the time they are writing up essays or watching videos. That is why Chromebooks are so popular in the first place. They are affordable, portable and long-lasting laptops. So, if you’re thinking about getting a Chromebook for yourself, keep on reading to figure out which one is best suited for you.

  • Orange Pi 3 single-board computer sells for $30 and up

    Shenzhen Xunlong Software has been selling single-board computers under the Orange Pi brand for years. The name is obviously inspired by the most famous low-cost, low-power SBC, the Raspberry Pi. But while Orange Pi devices don’t have the same level of community support as their Raspberry Pi rivals, they often make up for it by offering a decent set of features at an affordable price.

    Case in point: the company’s new Orange Pi 3 models sell for between $30 and $40 and offer offer a number of features (some optional, some standard) that you don’t get with the latest Raspberry Pi models.

  • We Need Open Hosting Platforms

    I think he’s starting with a reasonable, positive call: we can’t just decry the state of things, we have to make things. And we have to make good things. The open web should be better.

    I fear a moralizing approach to advocacy pushes people away, makes it harder for people to care about the values we are espousing. When we frame something as depressing or hopeless we encourage people to pay attention to other things. So yes: the open web should be the best web.

    But ignoring my advice, I’m going to point out a depressing fact: open source products aren’t successful. Open source is not in line to be part of any solution.

    Open Source has done a lot for developers, but it’s not present on the surface of the web – the surface that people interact with, and that defines the “open web”. Actual sites. Actual interfaces. Open source is used everywhere except at the point of interaction with actual people.

  • Compact Bay Trail SBC has option for third GbE port

    Axiomtek’s “CAPA84E” is a 3.5-inch Bay Trail SBC with an optional third GbE port, dual M.2 slots, plus VGA, DisplayPort, USB 3.0, SATA, and -20 to 70°C support.

    Axiomtek’s motto may well be: “If first you succeed, iterate until you don’t.” The king of the spinoffs has released yet another iteration of one of the first Intel Bay Trail SBCs, the CAPA841, which in 2015 was followed by the slightly scaled down CAPA840. The new CAPA84R similarly supports Bay Trail and conforms to the 3.5-inch form factor, but with a different mix of features.

  • Containers On The Edge

    There are two major families for the choice of operating system and ecosystem: RTOS-based and Linux-based families. Smaller, cost-constrained devices tend to benefit from the simplicity of RTOS-based, while more full-featured and complex devices benefit from the richness of Linux (see The Shift to Linux Operating Systems for IoT for more background on the reasons for these approaches in IoT). Linux has been used in embedded devices for almost as long as it has existed (see here for an excellent timeline of early embedded Linux usage by Chris Simmons). The focus here is on Linux based products, as they have the needed functions such as access controls and memory segregation that allows for upgrading portions in a controlled fashion.

  • YouTuber Fits A Fully Functional Computer Into A Mouse

    While the YouTuber’s original plan was to squeeze a Raspberry Pi inside of a regular computer mouse but was unable to do so due to size constraints. Hence, he 3D printed a computer mouse to fit the components of the computer inside the mouse.

    Dubbed as “The Computer Mouse”, the device consists of a Raspberry Pi Zero W computer, a 1.5-inch color OLED LCD display with a resolution of 128 x 128 pixels, a 3D-printed mouse, a rechargeable 500 mAh battery, and a tiny Bluetooth retractable keyboard for text inputs and more complicated commands. It also has a power button at the edge to start the tiny computer. Further, it runs GNU/Linux-based operating systems such as Raspbian.

  • MDN Changelog – Looking back at 2018

    December is when Mozilla meets as a company for our biannual All-Hands, and we reflect on the past year and plan for the future. Here are some of the highlights of 2018.

    The browser-compat-data (BCD) project required a sustained effort to convert MDN’s documentation to structured data. The conversion was 39% complete at the start of 2018, and ended the year at 98% complete. Florian Scholz coordinated a large community of staff and volunteers, breaking up the work into human-sized chunks that could be done in parallel. The community converted, verified, and refreshed the data, and converted thousands of MDN pages to use the new data sources. Volunteers also built tools and integrations on top of the data.

    The interactive-examples project had a great year as well. Will Bamberg coordinated the work, including some all-staff efforts to write new examples. Schalk Neethling improved the platform as it grew to handle CSS, JavaScript, and HTML examples.

  • SD Times Open-Source Project of the Week: Scylla

    With data having an impact on almost every part of today’s business, Scylla wants to make sure applications are powered by a database that can handle the influx of data without compromising performance.

    Scylla is a NoSQL database that provides low latency, always-on availability, high throughput, is scalable, easy to use, and community-backed.

    “Scylla is an open source NoSQL database that offers the horizontal scale-out and fault-tolerance of Apache Cassandra, but delivers 10X the throughput and consistent, low single-digit latencies. Implemented from scratch in C++, Scylla’s close-to-the-hardware design significantly reduces the number of database nodes you require and self-optimizes to dynamic workloads and various hardware combinations,” Peter Corless, technical marketing manager for Scylla, wrote in a post.

  • Winds of change? Winds of mediocrity.

    You'd think the world of open-source would escape this cheap reduction of human intellect. But no. The world's saddest violin is playing mightily loudly in the halls of Tux, too. Linux distributions are, by far and large, less stable, less ergonomic and less capable than they were five or six years ago. Lots of activity, few results.

    And when you do get results, they are made by devs for devs, object-oriented software solutions that intrude into the user space and complicate things without any benefits. Systemd is a good example. Wayland is another. Network tools yet another. Then, we also have the flattification of UI elements, the same kind of stuff that Google's been doing. And everyone is doing it, because hey, if Google does it, then if they imitate Google, they will be like Google, right. None of these things help, but we can tolerate them because they don't really make any difference in the overall story of human survival.

    [...]

    Don't embrace the change. Evaluate the change. Judge it. Be strict. Because we've come too far as a race to allow stupidity to become the driving factor. That's an insult to the billions of humans who have died to mosquitoes and common flu and famine so that we could reach an evolutionary point where people accept low-quality, low-efficiency nonsense into their lives, and then sermonize about that with the obtuse optimism of religiously passionate fanboys.

    But there's a happy side to this story, too. Not that long ago, I wouldn't contemplate rejecting the "modern" technology that much or that often. There was almost a thought of discomfort at such a move. But now? It does not seem so bad. Having gone through a few cycles of big tech changes, I don't see anything special or revolutionary in the Peckham water that companies are dishing out to the masses. It's an almost liberating thought, sprinkled with illumination, epiphany and other long words. Perhaps I should thank the agile crowds for this unintentional contribution of disdain and apathy. Good stuff, I'd say. Be if you're still out there, wondering if you can change the world, start by small things. Say no to stupid things. Don't embrace the change, embrace critical thinking.

  • Entry-level Bay Trail SBC ready for workhorse duty

    Acrosser’s 3.5-inch “AMB-BT19S1” SBC runs on an Intel Bay Trail SoC and offers up to 8GB RAM, dual display support, plus SATA, mSATA, mini-PCIe, serial, USB 3.0, and GbE ports.

    With newer Atom processor families such as Cherry Trail, Braswell, Apollo Lake, and now Gemini Lake, the popular, five-year old Bay Trail product line appears to be close to “legacy” status. Yet, aside from graphics capabilities and support for the latest memories and peripherals, there’s not that much separating Bay Trail from Gemini Lake in terms of CPU performance and power consumption. Depending on the price, an “entry level” Bay Trail SBC like Acrosser’s 3.5-inch AMB-BT19S1 board could be the smart move for some applications.

  • Smith and Winston Enters Early Access for Linux and Windows

    The rise of Geometry Wars 15 years ago on the original Xbox led to a slew of imitators across all platforms. However, the biggest thing it did was revive the long-dead twin-stick shooter genre. Small attempts had been made to revive it in the form of a new Robotron game in the late '90s, but nothing stuff until Bizarre Creations' fun little side game brought the shooting sub-genre back into the limelight again. Later full-fledged entries saw it gain even more popularity, and since then, it's had a bit of a downward turn once again. Enter Smith and Winston - beyond its gun brand-inspired name, you have a game that blends retro with modern in a unique way.

  • Etch a Sketch lives on in browser-based Chrome Labs project

    Everyone who remembers the Etch A Sketch slabs of yesteryear remembers how difficult it was to translate your vision onto its "magic screen," and how proud you felt upon success. Now, Google's Chrome Labs has translated that experience (quite literally) for the digital age with the fun Web A Skeb project. It's a browser-contained version of an Etch A Sketch that you can use to draw and doodle—if you can get the hang of its dials.

    [...]

    Google's Chrome Labs lets developers make weird, fun, and interesting projects to show the power that a simple Web browser has. Those involved have produced things like the open source image compression tool Squoosh, the Web actor library Clooney, and Project VisBug, a Chrome extension that lets users edit webpages using design tool interactions and hotkeys.

    Web A Skeb is available not only in Chrome but in other desktop and mobile browsers as well. It's actually a bit easier to draw on mobile, since you can use both of your thumbs to turn the dials at the same time. Those interested can check out the source code on GitHub.

  • AWS, MongoDB database collision stirs open source tensions

    AWS' introduction of the DocumentDB managed database service sparks competition with the backers of the popular MongoDB database, as well as debate over the nature of open source licensing.

    DocumentDB is a fully managed document database service that is compatible with MongoDB workloads. Rather than build on MongoDB's core code base, it implements an API that supports workloads from MongoDB 3.6 and earlier. This effectively emulates the responses that a MongoDB client expects from a MongoDB server, and customers can use their existing MongoDB drivers and tools, AWS said.

    MongoDB is the fifth-most popular database today, according to ranking site DB-Engines.com. Its parent company provides commercial support for the service, which went public in October 2017 and is now valued at more than $4 billion.

Being in Dallas also opens up huge opportunity to reach new audiences and new sponsors. Now to prove that.

  • Linux Fu: The Kitchen Sync

    One of the great things about Linux and similar operating systems is they are configurable. If you don’t like something, there’s a great chance you can change it easily with a few entries in a file somewhere. For example, take bash — a very popular shell by any measure. If you want a different style of command line editing, there’s an option. You want the tab key to match files regardless of case? Another option. Usually, these are set in one of your so-called profile files like .bashrc in your home directory.

    As long as you are sitting in front of your single computer working, this is great. You customize your .bashrc and other files to your heart’s content and then you work in an environment that acts the way you want it to. The problem is when you have a lot of computers. Maybe you have a web server, a desktop, a firewall machine, and a few dozen Raspberry Pi computers. How do you keep all the configurations the same? Then once they are the same, how do you keep them up to date?

  • AWS gives open source the middle finger

    AWS launched DocumentDB today, a new database offering that is compatible with the MongoDB API. The company describes DocumentDB as a “fast, scalable, and highly available document database that is designed to be compatible with your existing MongoDB  applications and tools.” In effect, it’s a hosted drop-in replacement for MongoDB that doesn’t use any MongoDB code.

    AWS argues that while MongoDB is great at what it does, its customers have found it hard to build fast and highly available applications on the open-source platform that can scale to multiple terabytes and hundreds of thousands of reads and writes per second. So what the company did was build its own document database, but made it compatible with the Apache 2.0 open source MongoDB 3.6 API.

  • Open-source microscope targets brain imaging and disease diagnosis

    A team of researchers at Tel Aviv University in Israel has developed a new multiphoton microscopy tool, known as Pysight, for rapid 2D and 3D imaging of the brain and other tissues.

    Among other things, the team hopes that the tool could soon boost scientists' efforts to attain a deeper understand of brain dynamics, assisting in the discovery of groundbreaking treatments for a range of health problems including stroke, epilepsy and dementia.

    Pablo Blinder, who heads up the team at the Neurobiology, Biochemistry and Biophysics School and Sagol School for Neuroscience at Tel Aviv University, explains that PySight combines commercially available, off-the-shelf hardware with open-source software tailored for photon-depleted imaging conditions, such as those characteristic of rapid multiphoton microscopy.

    “[PySight’s] commercial hardware converts the noisy output of each photodetector into uniform photon detection events, and registers their absolute arrival time with a temporal precision of 100 picoseconds,” he says.

    “Its software package then reads the resulting list of photon arrival times, determines the respective origin within the brain of each detected photon, and generates volumetric movies over time.”

    In a recent paper published in the journal Optica, Blinder and his co-authors demonstrate the benefits of using PySight for tracking neuronal activity in awake mice and fruit flies.

Excellent Utilities: lnav – the log file navigator

This is the second in a new series highlighting best-of-breed utilities. We’ll be covering a wide range of utilities including tools that boost your productivity, help you manage your workflow, and lots more besides.

And it supports a wide range of other log formats. For systems running systemd-journald, you can also use lnav as the pager.
