How I patched Python to include this great Ruby feature

Friday 17th of September 2021 06:11:22 AM
Ruby, unlike Python, makes lots of things implicit, and there's a special kind of if expression that demonstrates this well. It's often referred to as an "inline-if" or "conditional modifier", and this special syntax is able to return one value when a condition is true, but another value (nil, specifically) when a condition is false. Here's an example:read more

Programming Leftovers

  • Announcement : An AArch64 (Arm64) Darwin port is planned for GCC12

    As many of you know, Apple has now released an AArch64-based version of macOS and desktop/laptop platforms using the ‘M1’ chip to support it. This is in addition to the existing iOS mobile platforms (but shares some of their constraints). There is considerable interest in the user-base for a GCC port (starting with https://gcc.gnu.org/bugzilla/show_bug.cgi?id=96168) - and, of great kudos to the gfortran team, one of the main drivers is folks using Fortran. Fortunately, I was able to obtain access to one of the DTKs, courtesy of the OSS folks, and using that managed to draft an initial attempt at the port last year (however, nowhere near ready for presentation in GCC11). Nevertheless (as an aside) despite being a prototype, the port is in use with many via hombrew, macports or self-builds - which has shaken out some of the fixable bugs. The work done in the prototype identified three issues that could not be coded around without work on generic parts of the compiler. I am very happy to say that two of our colleagues, Andrew Burgess and Maxim Blinov (both from embecosm) have joined me in drafting a postable version of the port and we are seeking sponsorship to finish this in the GCC12 timeframe. Maxim has a lightning talk on the GNU tools track at LPC (right after the steering committee session) that will focus on the two generic issues that we’re tackling (1 and 2 below). Here is a short summary of the issues and proposed solutions (detailed discussion of any of the parts below would better be in new threads).

  • Apple Silicon / M1 Port Planned For GCC 12 - Phoronix

    Developers are hoping for next year's GCC 12 release they will have Apple AArch64 support on Darwin in place for being able to support Apple Silicon -- initially the M1 SoC -- on macOS with GCC. LLVM/Clang has long been supporting AArch64 on macOS given that Apple leverages LLVM/Clang as part of their official Xcode toolchain as the basis for their compiler across macOS to iOS and other products. While the GNU Compiler Collection (GCC) supports AArch64 and macOS/Darwin, it hasn't supported the two of them together but there is a port in progress to change it.

  • Dirk Eddelbuettel: tidyCpp 0.0.5 on CRAN: More Protect’ion

    Another small release of the tidyCpp package arrived on CRAN overnight. The packages offers a clean C++ layer (as well as one small C++ helper class) on top of the C API for R which aims to make use of this robust (if awkward) C API a little easier and more consistent. See the vignette for motivating examples. The Protect class now uses the default methods for copy and move constructors and assignment allowing for wide use of the class. The small NumVec class now uses it for its data member.

  • QML Modules in Qt 6.2

    With Qt 6.2 there is, for the first time, a comprehensive build system API that allows you to specify a QML module as a complete, encapsulated unit. This is a significant improvement, but as the concept of QML modules was rather under-developed in Qt 5, even seasoned QML developers might now ask "What exactly is a QML module". In our previous post we have scratched the surface by introducing the CMake API used to define them. We'll take a closer look in this post.

  • cuplTag battery-powered NFC tag logs temperature and humidity (Crowdfunding) - CNX Software

    Temperature and humidity sensors would normally connect to a gateway sending data to the cloud, the coin-cell battery-powered cuplTag NFC tag instead sends data to your smartphone after a tap. CulpTag is controlled by an MSP430 16-bit microcontroller from Texas Instruments which reads and stores sensor data regularly into an EEPROM, and the data can then be read over NFC with the tag returning an URL with the data from the sensor and battery, then display everything on the phone’s web browser (no app needed).

  • A first look at Microchip PolarFire SoC FPGA Icicle RISC-V development board - CNX Software

    Formally launched on Crowd Supply a little over a year ago, Microchip PolarFire SoC FPGA Icicle (codenamed MPFS-ICICLE-KIT-ES) was one of the first Linux & FreeBSD capable RISC-V development boards. The system is equipped with PolarFire SoC FPGA comprised a RISC-V CPU subsystem with four 64-bit RISC-V (RV64GC) application cores, one 64-bit RISC-V real-time core (RV64IMAC), as well as FPGA fabric. Backers of the board have been able to play with it for several months ago, but Microchip is now sending the board to more people for evaluation/review, and I got one of my own to experiment with. That’s good to have a higher-end development board instead of the usual hobbyist-grade board. Today, I’ll just have a look at the kit content and main components on the board before playing with Linux and FPGA development tools in an upcoming or two posts.

  • What is IoT device management?

    Smart devices are everywhere around us. We carry one in our pocket, watch movies on another while a third cooks us dinner. Every day there are thousands of new devices connecting to the Internet. Research shows that by 2025, more than 150,000 IoT devices will come online every minute. With such vast numbers it is impossible to keep everything in working order just on your own. This brings the need for IoT device management. But what is IoT device management? To answer this question we first need to understand what the Internet of Things (IoT) is.

  • KWinFT Continues Working On WLROOTS Render, Library Split

    KWinFT as a fork of KDE's KWin X11/Wayland compositor code continues making progress on driving fundamental display improvements and ironing out the Wayland support.  KWinFT has been transitioning to use WLROOTS for its Wayland heavy-lifting and that process remains ongoing. KWinFT has also been working on splitting up its library code to make it more manageable and robust.  Among the features still desired by KWinFT and to be worked on include input methods, graphical tablet support, and PipeWire video stream integration. Currently there are two full-time developers working on the project but they hope to scale up to four to five full-time developers.

    Not only is Intel progressing with its open-source ray-tracing driver support but the Mesa Radeon Vulkan driver "RADV" has been rounding out its RT code too and now has multiple games correctly rendering. Bas Nieuwenhuizen has been spearheading the RADV work on Vulkan ray-tracing support and after more than a half-year tackling it things are starting to fall into place nicely.Games such as Quake II RTX with native Vulkan ray-tracing are working along with the game control via VKD3D-Proton for going from Direct3D 12 DXR to Vulkan RT. Metro Exodus is also working while Ghostrunner and Doom Eternal are two games tested that are not yet working.
