The 10 Best Linux Network Monitoring Tools

Having total control over your network is essential to prevent programs from overusing your network resources and slowing down the overall performance. This is why you should install a network monitoring tool on your system, giving you a visual overview of everything that’s happening on your network. To help you out, we have put together a list of the ten best Linux network monitoring tools. All the tools mentioned here are open-source and follows an easy and intuitive UI (mostly command-line based) to help you monitor the bandwidth usage on your network.

Programming: GNOME, CI/CD, Go and Qt

• Bilal Elmoussaoui: libhandy-rs v0.6.0 is out!

  Recently I kind of took over the maintainership of libhandy-rs, the Rust bindings of libhandy. I have since then been preparing for a new release so that Rust & GTK app developers can update to the latest gtk-rs release as soon as possible. I also heavily depend on it on my various little apps.

• Easily speed up CI by reducing download size

  Every time a CI pipeline runs on GitLab, it downloads the git repository for your project. Often, pipeline jobs are set up to make further downloads (of dependencies or subprojects), which are also run on each job.

• What you need to know about automation testing in CI/CD

  Test automation means focusing continuously on detecting defects, errors, and bugs as early and quickly as possible in the software development process. This is done using tools that pursue quality as the highest value and are put in place to ensure quality—not just pursue it. One of the most compelling features of a continuous integration/continuous delivery (CI/CD) solution (also called a DevOps pipeline) is the opportunity to test more frequently without burdening developers or operators with more manual work. Let's talk about why that's important.

• Generics for Go

  The Go programming language was first released in 2009, with its 1.0 release made in March 2012. Even before the 1.0 release, some developers criticized the language as being too simplistic, partly due to its lack of user-defined generic types and functions parameterized by type. Despite this omission, Go is widely used, with an estimated 1-2 million developers worldwide. Over the years there have been several proposals to add some form of generics to the language, but the recent proposal written by core developers Ian Lance Taylor and Robert Griesemer looks likely to be included in a future version of Go. [...] Generics, also known as "parameterized types" or "parametric polymorphism", are a way to write code or build data structures that will work for any data type; the code or data structure can be instantiated to process each different data type, without having to duplicate code. They're useful when writing generalized algorithms like sorting and searching, as well as type-independent data structures like trees, thread-safe maps, and so on. For example, a developer might write a generic min() function that works on all integer and floating-point types, or create a binary tree that can associate a key type to a value type (and work with strings, integers, or user-defined types). With generics, you can write this kind of code without any duplication, and the compiler will still statically check the types.

• Fixing a common antipattern when loading translations in Qt

  I’m a Polish guy working with computers, mostly on Windows. However, the lingua franca of the IT industry is English, so every time I see a tutorial for some dev tool, it’s in that language. To lessen the burden of decoding which menu entry in the tutorial corresponds to which menu entry on my PC I decided to run the system with an English display language. I still want the rest of the i18n-related stuff (date format, keyboard, currency etc.) to be in Polish however. [...] As you can see, Thunderbird and Windows Settings show up in English but Qt Linguist is encrypted with some overengineered Slavic cipher (aka Polish language). What I further noticed, is that this incorrect language selection is particularly prevalent in Qt-based applications. Subsequent digging revealed that this antipattern is widespread in Qt world, see the relevant GitHub search (requires login).

• Top 6 Open Source Bitcoin Wallets, Rated and Reviewed for 2020

  The biggest appeal of open source wallets is that their code can be reviewed and publicly audited for potential security issues. As a result, open source software is often more robust than closed-source. The same goes for bitcoin wallets. [...] Whether you’re a beginner who needs a fantastic UI to help you navigate the intricacies of an open source wallet or you’re a developer who needs a platform that allows you to build on a secure base, these wallets will give you everything you’re looking for.

       

• Android 10 has the fastest update rate ever, hits 16% of users in 10 months

  Google today dropped a blog post detailing its progress on improving the Android ecosystem's update speed. The company has been hard at work for the past few years modularizing Android, with the hope that making Android easier to update would result in device manufacturers pushing out updates faster. Google's efforts have been paying off, with the company announcing Android 10 has had the fastest rollout ever. The last few versions of Android have each brought a major improvement to Android's update system. Android 8 introduced Project Treble, which separated the OS from the hardware support, enabling easier porting of Android across devices. In Android 9 Pie, Google completed its work on Treble and started publishing Generic System Images (GSIs): drop-in versions of Android that work on any Project Treble-compatible device. Android 10 introduced Project Mainline and the new APEX file type designed for updatable lower-level system components, delivered through the Play Store. Google's stats show that all this work is actually improving the ecosystem. "Thanks to these efforts," Google writes, "the adoption of Android 10 has been faster than any previous versions of Android. Android 10 was running on 100 million devices 5 months post launch—28% faster than Android Pie."

• What’s up with the Kubernetes ecosystem

  This week’s acquisition of Rancher Labs by the veteran enterprise Linux firm SUSE neatly illustrates the growing momentum of container-based application deployment. It also underlines the importance of Kubernetes as the orchestration tool of choice for managing all those containers. So, what does this latest move mean for the broader Kubernetes ecosystem? When containers first garnered corporate attention six or seven years ago, Docker and its tools were the centre of attention. But the focus soon shifted to management frameworks capable of automating the deployment and scaling of containers, and Kubernetes, developed by Google from technology used in its cloud platform, quickly won out. Like many open source tools, Kubernetes has its share of rough edges and does not necessarily provide all the capabilities that users need to build a functioning container-based infrastructure. Companies such as Rancher sprang forth to provide a complete software stack built around Kubernetes for those who didn’t want to build it all themselves.
