  • MuseScore 3.4 Release

    Today we are pleased to announce another significant update, MuseScore 3.4. In addition to dozens of bug fixes, it introduces UX improvements when working with score elements and telemetry.

  • Music Notation Software MuseScore 3.4 Released!

    Right-click on the Appimage, then go to Properties -> Permissions, check the box ‘Allow executing file as program’. Finally run the Appimage to launch MuseScore 3.4 and enjoy!

    MuseScore also available as Snap (runs in sandbox), which can be installed directly from Ubuntu Software, though it’s still v3.3.4 at the moment.

    Also the flathub repository contains MuseScore flatpak package....

  • announcing arduino-copilot

    arduino-copilot, released today, makes it easy to use Haskell to program an Arduino. It's a FRP style system, and uses the Copilot DSL to generate embedded C code.

    [...]

    Copilot is quite an impressive embedding of C in Haskell. It was developed for NASA by Galois and is intended for safety-critical applications. So it's neat to be able to repurpose it into hobbyist microcontrollers. (I do hope to get more type safety added to Copilot though, currently it seems rather easy to confuse eg miles with kilometers when using it.)

    I'm not the first person to use Copilot to program an Arduino. Anthony Cowley showed how to do it in Abstractions for the Functional Roboticist back in 2013. But he had to write a skeleton of C code around the C generated by Copilot. Amoung other features, arduino-copilot automates generating that C skeleton. So you don't need to remember to enable GPIO pin 13 for output in the setup function; arduino-copilot sees you're using the LED and does that for you.

    frp-arduino was a big inspiration too, especially how easy it makes it to generate an Arduino sketch withough writing any C. The "=:" operator in copilot-arduino is copied from it. But ftp-arduino contains its own DSL, which seems less capable than Copilot. And when I looked at using frp-arduino for some real world sensing and control, it didn't seem to be possible to integrate it with existing Arduino libraries written in C. While I've not done that with arduino-copilot yet, I did design it so it should be reasonably easy to integrate it with any Arduino library.

  • LibreOffice 6.4 RC3 is available

    LibreOffice 6.4 RC3 is available for downloading now. There are builds for all main OS for 64 bit. There is a 32 bit build for Windows also. These builds are only for testing.

VirtualBox 6 review - Not bad, not bad at all

Software
Reviews

When it comes to virtualization - mostly semi-pro or casual usage you'd find in a typical nerd setting, VirtualBox offers an excellent bundle of goodies; a friendly UI, lots of features, reasonable performance, simple and advanced options to suit every skill and mood. I've written about VirtualBox many times in the past, reviewing a whole range of topics, from the Guest Additions configuration to sharing & port-forwarding and then some. Several dozen articles to be more precise. Including major release reviews among them, of course.

Recently, VirtualBox 6.X has been released, so I thought this would be a good opportunity to take a look at what's new, check some of the improvements and fixes, and see whether you should move off the 5.X branch onto the latest edition. Come along, let's see what gives.

  • AWS outage cripples ACT Emergency Services Agency website as Canberra bushfire rages

    The outage hit as Canberra Airport was shut to commercial traffic because of the fire, with residents around Oaks Estate warned to get out of the road of the oncoming blaze after two fires merged and engulfed a rubbish tip.

    It is still unclear why the ESA website was hit by a single point of failure, however the blaze, known as the Beard fire, is burning close to the industrial suburb of Fyshwick which houses several data centres.

    The blaze near the airport is also within stone's throw of the the Australian Signals Directorate's Australian Cyber Security Centre offices at the Brindabella Park office complex that houses a clutch of other technology, consulting and miltech tenants.

  • The Pentagon CIO office's plan for better software

    In his speech, Ranks detailed several efforts underway at the DoD to increase update speed. To start, Ranks said, the DoD CIO's office is changing policy to allow for more iterative processes in acquisition, a departure from the current process where requirements are laid out years before technology is delivered. To complete that goal, Ranks said the DoD needs the enterprise capability to provide the tools necessary to create a more iterative process.

Use tmux to create the console of your dreams

Filed under
Software

In this series so far, I've written about individual apps and tools. Starting today, I'll put them together into comprehensive setups to streamline things. Starting at the command line. Why the command line? Simply put, working at the command line allows me to access a lot of these tools and functions from anywhere I can run SSH. I can SSH into one of my personal machines and run the same setup on my work machine as I use on my personal one. And the primary tool I'm going to use for that is tmux.

Most people use tmux for very basic functions, such as opening it on a remote server then starting a process, maybe opening a second session to watch log files or debug information, then disconnecting and coming back later. But you can do so much work with tmux.

  • WinFF on Ubuntu: Video/Audio Conversion Made Easy

    WinFF is an Ubuntu application to convert multimedia files in easy way. It is an alternative (replacement) to Any Video Converter or FormatFactory from Windows; so you can do audio/video conversions in ways you are familiar to as well on GNU/Linux. WinFF can convert all formats, including the popular MP4, MP3, OGV, OGG, FLV, WMV, WEBM, and MKV. Actually, it is a visual version of FFmpeg command line, hence the name WinFF. This tutorial explains how to install it on Ubuntu and give you example in using it. Enjoy!

  • Converseen is an open source batch image processor for Windows and Linux

    Batch tools are efficient time-savers when you need to manipulate more than one or two images provided that the intended operations are identical. Converseen is an open source image processor that's available for Windows and Linux that may help you in that case.

    [...]

    The program can be used to convert, resize, rotate and flip several images with a few clicks. It is based on ImageMagick, the open source image editor.

    Converseen's interface is divided into two panes: the actions panel is to the left, and to the right you have the convert list. A menu bar and a toolbar are placed at the top of the screen.

    Use the File menu or the Open Images/Add Images button to get starte, or just drag and drop some files to the right pane. It will display the file name, type, and size of each individual image you added to the program. A checkbox is placed next to each image in the list, and only the marked ones will be converted. Use the Edit menu to check/uncheck all files in a single click.

  • Feral's GameMode 1.5 Now Supports Changing The CPU Governor Differently For iGPUs

    With Feral's GameMode 1.5 the big change facing users is for those running integrated graphics. In a change led by an Intel open-source graphics driver developer, GameMode now supports setting an alternative CPU frequency scaling governor for integrated graphics use-cases. Up to now GameMode has defaulted to always using the "performance" CPU frequency scaling governor for normally delivering the best performance, but for integrated graphics that in some situations can lead to lower performance. Due to the integrated graphics and CPU cores sharing the same power envelope, ramping up the CPU performance can throw the graphics performance out of balance and at least for some games lead to lower performance. So with GameMode 1.5, the user can now opt for "powersave" or an alternative governor instead when using an iGPU.

  • Feral Interactive's open source 'GameMode' system performance booster has a new release

    Feral Interactive don't just port a lot of games to Linux, they also work on some open source bits here and there. One of their projects is GameMode, which just got a new release.

    GameMode is a "daemon/lib combo for Linux that allows games to request a set of optimisations be temporarily applied to the host OS and/or a game process". In simple terms, it can help ensure your Linux PC is giving the game all it can to run smoothly. Looks like someone new is handling the project too, with Alex Smith having left Feral Interactive.
