    croc is a free and open source cross-platform P2P command line tool for secure file transfers between computers

    Danie van der Merwe · news.movim.eu / gadgeteerza-tech-blog · Yesterday - 09:27

It uses relay-assisted peer-to-peer transactions and end-to-end encryption via password-authenticated key exchange. The program is written in Go and is available for Microsoft Windows, macOS, Linux and *BSD.

The idea behind croc is being able to transfer files and folders between cross-platform computers securely, fast and easy. With support for resumable, peer-to-peer transfers. As a bonus feature, croc is also able to securely transfer a short text or URL directly.

The data transfer is done using a relay, either using raw TCP sockets or websockets. When the sender and the receiver are on the same LAN, croc uses a local relay, otherwise a public relay is used. Thanks to this, croc can send files between computers in the same LAN, or over the Internet, without having port-forwarding enabled.

    5 useful Moodle plugins to engage students - Use plugins to give your e-learning platform new capabilities that motivate students

    Danie van der Merwe · news.movim.eu / gadgeteerza-tech-blog · 2 days ago - 13:21

A good e-learning platform is important for education all over the world. Teachers need a way to hold classes, students need a friendly user interface to facilitate learning, and administrators need a way to monitor the educational system's effectiveness.

Moodle is an open source software package that allows you to create a private website with interactive online courses. It's helping people gather virtually, teach and learn from one another, and stay organized while doing it.

What makes Moodle unique is its high usability that can significantly increase with third-party solutions. If you visit the Moodle plugins directory, you'll find over 1,700 plugins developed by the open source community.

    Canonical Chooses Google’s Open Source Cross-Platform Flutter UI SDK to Build Future Ubuntu Apps

    Danie van der Merwe · news.movim.eu / gadgeteerza-tech-blog · 2 days ago - 13:05

For those not in the know, Flutter is an open-source UI SDK (software development kit) created by Google to helps those who want to build quick and modern applications for a wide-range of operating systems, including Android, Linux, Mac, iOS, Windows, Google Fuchsia, that work across desktop, mobile, and the Web.

The company behind Ubuntu is writing another page of history by targeting Flutter as the default UI (user interface) framework for building their own Ubuntu apps, which will work across a wide-range of hardware and configurations.

    How To Use VIM Editor - Because if you've not used it for years you won't be able to exit it

    Danie van der Merwe · news.movim.eu / gadgeteerza-tech-blog · 3 days ago - 20:57

Yes VIM Editor is renowned for its flexibility and power (probably second to none) but it does not follow any of the current conventions even for cut-and-paste, or scrolling around, or exiting. So most people, like me, who start it up to test it out, have to do an Internet search to figure out how to exit it. Just remember :h for help and :wq for save and exit.

The article below scratches the surface in terms of the very basics but does not cover any of the more detailed functionality of plugins that VIM can use. It does give some idea though that if you use a number of steps regularly, there is a lot of power in using VIM. You either love VIM or you hate it ;-)

    My observations after returning back to an iPhone after 9 years of using Android

    Danie van der Merwe · news.movim.eu / gadgeteerza-tech-blog · 5 days ago - 17:05 edit · 3 minutes

I sold my jailbroken iPhone 3 back in January 2011 and have been using rooted Android phones for the last 11 years. The reason I returned to an iPhone were mainly that I love change (has the iPhone improved?), Apple has been doing a good job on privacy (versus Google), I had a disastrous experience with the Nexus 6P battery, my Pixel 2 XL has stopped getting updates after 3 years (iPhone is good for 6 to 7 years), The Apple Watch is just better than any other watch (apart from battery life) and my medical insurance funds an iPhone and Apple Watch almost for free. I got the iPhone 12 Pro and the Series 6 non-cellular Apple Watch in 44mm size.

So now that's out of the way let me say I'm happy with the iPhone as far as stability, battery life, wide angle camera, I can use my own Keyboard and browser, and the quality of apps go. Yes the Watch does need to be charged daily, but I can get a full day's heavy use out of it, and I do love its interface and better health data. I've been using both for 3 weeks now so all is good, but I just have a few things that do bug me that are worth noting for Apple users as I'd really like Apple to just address some of these:

  • There is nothing that touches the Tasker app on iOS. Yes Shortcuts makes a good attempt, but it can be vastly expanded even if just on the reading of data for triggers. I can't even set up a shortcut to trigger if I lose a WiFi network. It has great potential though.

  • No call recording (which is legal in many countries, and the 3rd party line is not an option outside the USA, Android of course needed to be rooted for this anyway) - I got around this by buying the RecorderGear PR200 Bluetooth device which will work with iOS and Android.

  • Call line identifiers such as TrueCaller and similar, are crippled. They work fine on Android, but some functions disable in the background even though they replace the default iOS phone app.

  • Some apps which you've bought a lifetime usage on Android (eg. FaceApp), do not transfer to iOS, but the same goes for moving from iOS to Android. Others which just rely on a login, such as TrueCaller and Pocket Casts, do work fine.

  • PushBullet does not work on iOS, to copy clipboard info from my Linux computer. I struggled a bit with alternatives as there are few, but I did in the end find an app called 'Clipboard - Paste Anywhere' which is doing what I need.

  • Home screen icons and groups have improved but no built-in support for renaming an app icon or changing the icon (because sometimes you must use 3rd party apps, and you forget what they are for). I did find a Shortcut routine which is doing what I wanted, but the downside is no indicators show for message counts.

  • Alerts were not sounding properly on the phone eg. for Telegram and Ring Doorbell, but I realised you need to disable their alerts to the Watch, then phone notifications sound properly.

  • My Chargie hardware device (to stop battery charging at a determined percentage) does not have an iOS app yet. There is built-in OS optimised charging, but that still charges a full cycle up to 100%. This is also not the fault of Apple though.

  • USSD messages appear in a clunky fashion like SMS test messages instead of the straight pop up view on Android. Hopefully this just gets streamlines and I must report it as feedback to Apple.

  • No battery usage by app on the Watch so difficult to know which apps are going rogue on battery usage.

  • Although the quality of apps is noticeably better, there is a lack of any apps for some Fediverse social networks such as Pixelfed, Tox, XMPP, and others. This is not Apple's fault at all but is an inconvenience I suppose for someone used to testing lost of alternative network apps.

Otherwise, all is actually good, and I'm looking forward to sweating out a good 5 or 6 years at least with this phone. It is comforting to know firstly there are software and security updates for years to come, and secondly that I can go to Apple and get a battery etc replaced (that was just not an option for the Pixel phones). So I'm enjoying using the phone as I can appreciate what both Apple and Google do well, and what they both don't get right yet. Neither are perfect!

    The Framework Laptop: Upgradeable, repairable, and 100% yours

    Danie van der Merwe · news.movim.eu / gadgeteerza-tech-blog · 5 days ago - 14:32

It’s time for long-lasting products that respect your right to repair and upgrade.

The single best way to reduce the environmental impact of electronics is to make them last longer. You can repair and upgrade the Framework Laptop to make it work great for as long as you need it to. On top of that, it uses a 50% post consumer recycled (PCR) aluminium housing, 30% PCR plastic, and fully recyclable materials for packaging.

Built-in hardware privacy switches give you complete control over access to the camera and microphones. Their embedded controller firmware is fully open source, and they claim not to preload any extra software.

It is expected to ship by the Summer of 2021 (Northern Hemisphere?).

    Monitor your Raspberry Pi with a free Grafana Cloud account, or host open source Grafana yourself

    Danie van der Merwe · news.movim.eu / gadgeteerza-tech-blog · 5 days ago - 11:35

You may have heard of Grafana, a time-series dashboarding tool that helps you discover what's going on in your environment. People from hobbyists to enterprise professionals like to use it for visualizations because it is open source and can accept data from myriad sources. This article describes how to use it to monitor your Raspberry Pi as an example of Internet of Things (IoT) monitoring.

It uses Grafana's latest offering, Grafana Cloud, a hosted free version that requires a lot less work than setting it up yourself. You can do everything in this article by downloading and installing Grafana, but the hosted version is convenient and lets you focus on other work (assuming your Raspberry Pi is connected to the Internet).

    Singapore reveals open-source blockchain COVID-test result tracker, eyes uses as vaccine passport app

    Danie van der Merwe · news.movim.eu / gadgeteerza-tech-blog · 6 days ago - 11:40

Singapore has proposed a blockchain-based document verification system developed by its GovTech agency to provide proof of recent negative COVID-19 tests, and hopes it becomes used to offer proof of vaccination status around the world.

Named "HealthCerts", the system is based on open-source framework known as OpenAttestation that uses blockchain to issue cryptographically trustworthy documents. The technology is already applied by some local universities to issue and authenticate diplomas.

Singapore’s Minister of Foreign Affairs, Vivian Balakrishnan said last week that the technology is “globally inter-operable” and that Singapore therefore hopes to share it with the world to facilitate more cross-border travel.
