Emmanuele Bassi: GWeather next

Filed under
Development
GNOME

Libgweather, the small GNOME library that queries weather services, is getting a major version bump to allow applications using it to be ported to GTK4.

In the beginning, there was a weather applet in the GNOME panel. It had a bunch of code that poked at a couple of websites to get the weather information for a given airport or weather observation stations, and shipped with a list of locations and their nearest METAR code.

In 2007, the relevant code was moved to its own separate repository, so that other applications and system settings could reuse the same code as the panel applet: the libgweather library was born. Aside from the basic weather information and location objects, libgweather also had a couple of widgets: one for selecting a location (with autocompletion), and one for selecting a timezone using a location.

Since libgweather was still very much an ad hoc library for a handful of applications, there was no explicit API and ABI stability guarantee made by its maintainers; in fact, in order to use it, you had to “opt in” with a specific C pre-processor symbol.

Time passed, and a few more applications appeared during the initial GNOME 3 cycles—like Weather, followed by Clocks a month later. Most of the consumers of libgweather were actually going through a language binding, which meant they were not really “opting into” the API through the explicit pre-processor symbol; it also meant that changes in the API and ABI could end up being found only after a libgweather release, instead of during a development cycle. Of course, back then, we only had a single CI/CD pipeline for the whole project, with far too little granularity and far too wide scope. Still, the GWeather consumers were few and far between, and the API was not stabilised.

System Monitoring Center is an Ideal Task Manager & Resource Monitor for Linux

Graphically monitoring the system resources may not be the best experience on Linux. The system monitoring tool that comes baked in with your desktop environment might limit the details. For instance, GNOME’s system monitor does not display the CPU frequency and temperatures. In addition, the default system monitor applications available for Linux usually aim for simplicity instead of providing detailed insights. Read more

  • How Ubuntu Boosts Developer Desktop Productivity | Ubuntu

    Seventeen years after its first release, Ubuntu is firmly established as the Linux developer desktop of choice around the world. From education through to enterprise, Ubuntu delivers the tools developers need to succeed across their careers. In this blog, we will cover the main aspects that contribute to this success. [...] Developers start their careers with Ubuntu, and 69% of student developers reported that they prefer Ubuntu as an OS. It’s not surprising. With Ubuntu, they gain access to the best of open source, including AI/ML frameworks, such as Pytorch and TensorFlow, ROS for robotics and LXD and multipass for virtualisation. Open source technology is now a critical part of any enterprise, and familiarity with open source is a key consideration in hiring. As a result, getting new developers onboarded and productive quickly is easier with Ubuntu. It’s a system they’re familiar with. It’s flexible and customisable. And, as an operating system, it spans both the workstation and the cloud, providing a consistent development experience across your technology stack.

  • Our 12 favorite Arduino UNO projects | Arduino Blog

    The UNO wasn’t Arduino’s first board, and it won’t be its last. There have been many varieties of microcontroller and maker boards before and after the UNO, but none have been as iconic. As we cross the epic milestone of 10 million UNOs sold and the launch of the UNO Mini Limited Edition, we decided it was time to take a look back at some of our favorite UNO projects from the last 10 years. And we want to hear about yours, too. Join us over on social media to share your favorite UNO projects, whether you built them yourself or marveled at someone else’s electronic creation.

  • Personal computer maker Raspberry Pi plans London listing

    The company behind Britain's best-selling personal computer is preparing the ground for a spring listing which is expected to value it at more than £370m.

    The trading arm of the Raspberry Pi Foundation has hired bankers from Stifel and Liberum to advise on a London float after securing a $45m (£33m) investment in September.

    The Cambridge-based foundation offloaded stakes to Lansdowne Partners and the Ezrah Charitable Trust to fund product development and marketing after seeing booming demand for its miniature personal computers during lockdown.

  • Mozilla Privacy Blog: Mozilla files comments on UK Data Protection Consultation

    Mozilla recently submitted its comments to a public consultation on reforming the UK’s data protection regime launched by the UK Department for Digital, Culture, Media & Sport. With the public consultation, titled ‘Data: A New Direction’, the UK government set out to re-evaluate the UK’s approach to data protection after no longer being bound by the bloc’s General Data Protection Regulation (GDPR). We took this opportunity to share our thoughts on data stewardship and the role effective regulation can play in addressing the lopsided power dynamics between large data collectors and users. For Mozilla, privacy is not optional. It is an integral aspect of our Manifesto, which states that individuals’ security and privacy on the internet are fundamental and must not be treated as optional. This is why privacy is at the core of our product work and why we have long promoted robust data protection in our policy and advocacy work. Further, Mozilla’s Data Futures Lab is exploring alternative approaches to data governance and promoting data stewardship through original research and support to builders.

  • 42 things I learned from building a production database

    In 2017, I went to Facebook on a sabbatical from my faculty position at Yale. I created a team to build a storage system called Delos at the bottom of the Facebook stack (think of it as Facebook’s version of Chubby). We hit production with a 3-person team in less than a year; and subsequently scaled the team to 30+ engineers spanning multiple sub-teams. In the four years that I led the team (until Spring 2021), we did not experience a single severe outage (nothing higher than a SEV3). The Delos design is well-documented in two academic papers (in OSDI 2020 and SOSP 2021). Delos is currently replacing all uses of ZooKeeper at Facebook.

    Here are some of the things I learned as the tech lead for Delos. My intent in publishing this is to help others in similar roles (leading teams that are building new infra at large companies); much of it may not generalize to different settings.
