  • Expect A 20% Rise In Your RAM Usage As Multi-process Feature Is Coming To Firefox

    Stepping up its game in the war of browsers, Mozilla is moving ahead to bring multi-process architecture in Firefox this April. While users are having reservations about the resultant RAM increase, a Mozilla engineer has performed benchmarking tests and claimed that users will notice a memory hike between 10% to 20%.

  • Our 2016 Fundraising Campaign

    The OpenBSD Foundation needs your help to achieve our fundraising goal of $250,000 for 2016.

    Reaching this goal will ensure the continued health of the projects we support, will enable us to help them do more, and will avoid the distraction of financial emergencies that could spell the end of the projects.

    2015 was a good year for the foundation financially, with funding coming almost equally from corporate and community donations. While the total was down significantly after 2014's blockbuster year, we again exceeded our goal.

    [...]

    If a penny was donated for every pf or OpenSSH installed with a mainstream operating system or phone in the last year we would be at our goal.

  • Write code that is easy to delete, not easy to extend.

    Every line of code written comes at a price: maintenance. To avoid paying for a lot of code, we build reusable software. The problem with code re-use is that it gets in the way of changing your mind later on.

    The more consumers of an API you have, the more code you must rewrite to introduce changes. Similarly, the more you rely on an third-party api, the more you suffer when it changes. Managing how the code fits together, or which parts depend on others, is a significant problem in large scale systems, and it gets harder as your project grows older.

Raspberry Pi CM3+ based SBC ships with CODESYS

Kontron’s “Pi-Tron CM3+” controller SBC is based on the Raspberry Pi CM3+ and offers 2x LAN, 2x USB, 2x COM, 2x DIO, CAN, micro-HDMI, MIPI DSI/CSI, 40-pin GPIO, and CODESYS support. Since Kontron acquired PiXtend’s line of Raspberry Pi based controllers a year ago, we have been waiting for some new Pi-based products from the German embedded computing firm. Kontron has now delivered with the Baseboard BL Pi-Tron CM3+, a sandwich-style SBC built around the Raspberry Pi Compute Module 3+ (CM3+). Read more

Best Free and Open Source Alternatives to Adobe Illustrator

Adobe is a large multinational computer software company with over 22,000 employees. Its flagship products include Photoshop, Illustrator, InDesign, Premiere Pro, XD, Acrobat DC, and the Portable Document Format (PDF). The products are wrapped up and marketed as the Creative Cloud, a subscription-only way of accessing more than 20 desktop and mobile apps and services for photography, design, video, web, UX, and more We are long-standing admirers of Adobe’s products. They develop many high quality proprietary programs. It’s true there are security and privacy concerns in relation to some of their products. And there’s considerable criticism attached to their pricing practices. But the real issue is Adobe Creative Cloud does not support Linux. And there’s no prospect of support forthcoming. What if you are looking to move away from Adobe and embark on a new world of online freedom, where you are not tracked, monetised and attached to Adobe’s ecosystem. We only recommend free and open source alternatives. Our recommended software don’t necessarily replicate every feature of their Adobe counterparts but they offer sufficient functionality for many tasks. Read more

  • IAR Systems extends functional safety offering for RISC-V with leading build tools for Linux

    IAR Systems®, the future-proof supplier of software tools and services for embedded development, today announced that its build tools for RISC-V supporting deployment in Linux-based frameworks have been certified by TÜV SÜD for functional safety development. The certification has been performed according to the requirements of IEC 61508, the international umbrella standard for functional safety, as well as ISO 26262, which is used for automotive safety-related systems. In addition, the certification covers the international standards IEC 62304 for medical software, IEC 60730 for Household Appliances, ISO 13849 and IEC 62061 for Machinery Control Systems, IEC 61511 for Process Industry, ISO 25119 for Agriculture and Forestry, and the European railway standards EN 50128 and EN 50657.

  • Allwinner D1s/F133 RISC-V processor integrates 64MB DDR2 - CNX Software

    Allwinner D1s (aka F133) is a cost-down version of Allwinner D1 RISC-V processor introduced earlier this year together with a Linux capable development board, with the main difference being the integrated 64MB DDR2. Besides the built-in RAM, Allwinner D1s comes with many of the same features as D1 RISC-V SoC, but loses HDMI output and the HiFi 4 audio DSP, and Allwinner made some tweaks to the IOs with one less I2S audio interface, and general-purpose ADC.

  • Smart Power 3 - A $45 smart power analysis tool for embedded systems developers - CNX Software

    Hardkernel has launched a number of popular Arm SBC’s with the ODROID family over the years, but the Smart Power 3 is a different type of product, as the ESP32-based smart power meter can help embedded systems engineers optimize their hardware and software power consumption and/or check for spurious power peaks during boot up or shutdowns. In the past, we’ve reviewed relatively expansive tools like Qoitech Otii Arc or gone the DIY route, but at $45, Hardkernel offers a power monitoring solution that’s both inexpensive and easy to use, albeit with fewer features than Qoitech’s device.

  • Omni-Wheeled Cane Steers The Visually-Impaired Away From Obstacles | Hackaday

    The cane uses a Raspi 4 with camera to detect objects, and a 2-D LIDAR to measure the distance to those objects. There’s a GPS and a 9-DOF IMU to find the position and orientation of the user. Their paper is open, too, and it comes with a BOM and build instructions. Be sure to check it out in action after the break.
