Displaying Problems inline in KDevelop

In 2018 the KTextEditor framework which powers the editor of KDevelop gained support for displaying inline notes enabling to show information inside the editor without interfering with the editing process. One of the prototypes shown during the development of the interface for displaying such notes was showing detetcted problems like compiler warnings and errors in the affected line. Being a KDevelop user for quite some time now I was excited about that feature when I read the blog post linked earlier. Unfortunately, it didn’t get implemented straight away and I forgot about it - until recently when the inline note cababilities were brought up on IRC. I though to myself: “How hard can it be?” And thanks to the incredible work done when implementing the InlineNote and related interfaces into KTextEditor and the extensible structure of KDevelop it wasn’t hard at all! The work needing to be done was basically plugging the two systems together and deciding how the notes should look like. Read more

  • WireGuard – A Fast, Modern and Secure VPN Tunnel for Linux

    WireGuard is a modern, secure, cross-platform and general-purpose VPN implementation that uses state-of-the-art cryptography. It aims to be speedy, simpler, leaner and more functional than IPsec and it intends to be more performant than OpenVPN. It is designed for use in various circumstances and can be deployed on embedded interfaces, fully loaded backbone routers, and supercomputers alike; and runs on Linux, Windows, macOS, BSD, iOS, and Android operating systems. It presents an extremely basic yet powerful interface that aims to be simple, as easy to configure and deploy as SSH. Its key features include a simple network interface, crypto key routing, built-in roaming and container support. Note that at the time of writing, it is under heavy development: some of its parts are working toward a stable 1.0 release, while others are already there (working fine).

  • Modern Computers Might Stop Working on January 19, 2038

    Nearly every computer in the history of computers keep time using a 32-bit integer, counting forward from 00:00:00 UTC on the 1st of January 1970, referred to as the epoch. This instant of time was set as the standard for modern computing systems, but there's a major problem. Seven seconds after 3:14 am UTC on the 19th of January 2038, the 32-bit integer storing this time data will run out of positions. The problem is similar to the Y2K issue where a 2-digit value could no longer be used to encode the years 2000 or later, but different in that this 32-bit bug is related to Unix-like systems and the Unix time format. These similarities to the Y2K bug have widely lead to the 2038 problem being known as the Unix Millennium Bug. [...] Embedded systems like those in cars and appliances are designed to last the lifecycle of the device without a software update. Connected electronics can be quickly fixed with a software update when the time comes, but these embedded systems will likely wreak the most havoc in 2038 since most won't be updated. One option is to change the data storage system of the 32-bit integer to an unsigned 32-bit integer. This would theoretically allow for date storage all the way to 2106, but any system that used a date prior to 1970 would run into issues accessing this data. If we increased the data storage to 64-bit, we would run into compatibility storage issues between older systems that only use 32-bit data storage. There's no current universal solution to the problem and even the most widely accepted fixes still have bugs in certain usage areas. There is positive news at the end of this.

The Chrome Cast 50: Linux on Chromebooks and the future of Chrome OS tablets

This week on The Chrome Cast, we’re exploring a couple seemingly-unconnected ideas that actually tie into one another quite well. First up is the heightened interest in Linux apps on Chrome OS. While we’ve been tracking along with the development of Crostini since before it was actually a thing, it’s been a while since we’ve really dug into what Chromebooks are capable of with Linux. As part of that renewed effort, we’ve launched Command Line, where we are focusing more on what users can do and get done with Linux apps on their Chromebook. Read more Another new show:
