Regain your focus: Manage your push notifications in Linux

Filed under
GNU
Linux

I have been working in a professional IT environment of a large organization for over 20 years and during that time I have seen a lot of different visions and opinions on individual and collective productivity. What I have noticed in all those years is how many people think that you are a bad-ass professional if you can do an insane amount of tasks simultaneously. But let’s be honest, doing many things at the same time is not the same as doing things right. But gradually, cracks start to appear in the common opinion that it is always good to multitask. More and more studies show that multitasking undermines focus. And focus is necessary to not waste valuable time due to finding back your concentration as a result of an attention switch. Focus makes sure that you can deliver some high-quality results instead of just many, but probably mediocre results. In this article I want to delve deeper into the backgrounds behind focus, productivity, the impact of notifications on your productivity, and the things that you should consider in allowing and managing your push notifications under Linux.

[...]

In the introduction I already indicated that nowadays we are increasingly questioning the importance of being good at multitasking, and that perhaps single-tasking is much better. There is, however, a nuance, since multitasking can be fine in itself, as long as all the tasks you want to perform don’t require an equal amount of brain activity and attention. For example, if you like to listen to music during your study time, it is better to listen to instrumental music instead of music in which lyrics play the leading role. With spoken text, you unconsciously interpret and shift your attention from your main task to the music, so you constantly need to refocus back again to your main task. But if you still want to listen to music with vocals, then it is advisable to only listen to music that you have known for years instead of listening to songs with song texts that you have never heard before. New texts subconsciously require more of your attention than texts that you have already known for years. Multitasking is therefore only great when it comes to a combination of simple activities alongside your main task, such as making simple sketches, creating doodles, playing with an elastic band, or chewing your pencil, during a colleague’s presentation or while reading an advice report or listening to a teacher. These doodles and fiddling with a piece of rubber do not require brain effort, so you can keep all your real focus on the main task. But constantly looking at your messages on your mobile phone while listening to a presentation of your colleague, will lead to a loss of focus and loss of information, and of course this is not the nicest and most respectful thing to do in front of a presenting colleague.

GNU: GDB (Debugger), Project's History, and GCC (Compiler)

  • GDB Debugger Adds Support For Debuginfod Web Server

    Debuginfod is the Red Hat led debug information HTTP web server distributed as part of elfutils and able to supply on-demand source code and ELF/DWARF debug files to debuggers / IDEs / other compiler tooling. The GDB debugger can now tap debuginfod for on-demand source files and debug information that isn't present on the local system.

    The motivation with debuginfod is to carry less developer "baggage" on local systems when it comes to debug files and potentially even source files. Particularly for organizations or cases like Linux distributions, a centralized debuginfod server could in turn supply the needed files to clients based upon the requested build ID. Red Hat has been working to expand the debuginfod support both for the GNU toolchain and also LLVM, among other possible users.

  • When is GOTS not in the national interest?

    The modern open-source software (OSS) movement can be traced back to the early 1980s with the birth of Richard Stallman’s GNU Project and the Free Software Foundation.

    [...]

    However, cost is a red herring for the real challenge presented by GOTS software solutions. On the surface, GOTS seems very similar to OSS which implies that it has the larger structural advantages of OSS. If handled cautiously, it can have those advantages, but care needs to be taken about what sort of existing software is being commoditized. The U.S. has a national interest in maintaining a strong software development capability. We are fortunate to be the dominant software-building country in the world. According to the Forbes 2000 list, the total market capitalization of U.S. internet, software, and computer services companies is close to $4.7 trillion — more than twice the rest of the world combined. Software tech is an enormous comparative advantage for the U.S. As a result, it is clearly in the national interest to have the government avoid directly competing against and potentially weakening the U.S. private sector.

  • New compiler added to popular studio for ARM and Cortex-M IDE

    The studio for ARM/Cortex-M is now supplied with three different compilers: GCC, Clang and the company's own compiler. The new compiler outperforms GCC and regular Clang on most benchmarks, decreasing both size of generated code as well as its execution speed.

Red Hat: The Vision of Fedora Project and Corporate IBM/Red Hat News

  • The Fedora Project's One Sentence Vision

    Fedora Project Leader Matthew Miller recently talked about his vision for the Fedora Project over the next decade and it to become an "operating system factory", among other advancements he hopes to see out of the project in the 2020s. A one-sentence vision for Fedora is now drafted as their vision statement.

  • Let’s keep writing a new vision statement for Fedora

    If you compare it to the first draft, you’ll notice we shortened it to one sentence. We kept the parts we felt were most important: everyone benefiting from free & open source software and the attributes of the communities that make it. The word benefit is important here. It’s not enough that the software is there, waiting to be used. It has to be accessible and usable. This was much longer in our first draft, so shortening it here seems right. We also cut out the sentence about Fedora being a reference for everyone who shares this vision. We still want to be that, but that’s implied by the fact that we have this vision in the first place. Why bother expressing a vision that we wouldn’t want to be an influential part of? And frankly, it’s hard to get the wording right, especially in a way that works across languages and cultures.

  • Enable Git Commit Message Syntax Highlighting in Vim on Fedora

    When setting up new machines, I’m often frustrated by lack of syntax highlighting for git commit messages in vim. On my main workstation, vim uses comforting yellow letters for the first line of my commit message to let me know I’m good on line length, or red background to let me know my first line is too long, and after the first line it automatically inserts a new line break whenever I’ve typed past 72 characters. It’s pretty nice. I can never remember how I get it working in the end, and I spent too long today trying to figure it out yet again. Eventually I realized there was another difference besides the missing syntax highlighting: I couldn’t see the current line or column number, and I couldn’t see the mode indicator either. Now you might be able to guess my mistake: git was not using /usr/bin/vim at all! Because Fedora doesn’t have a default $EDITOR, git defaults to using /usr/bin/vi, which is basically sad trap vim.

  • Executive Q&A: Stephen Leonard, GM of IBM’s Cognitive Systems

    There is no single path that business executives travel.

Our discussion covered a wide range of issues and events that have colored Leonard’s 30+ years with IBM.

  • IBM Sterling enables intelligent orchestration of customer transactions across back-end record systems

    A deep understanding of customers’ wants and needs are key to driving supply-chain efficiencies and enhanced customer experiences. An intelligent call center solution equips customer care representatives (CSRs) with deep insights in a natural language-based conversation interface to solve complex customer queries. On a typical day, a CSR opens multiple tabs/applications to address a single query, spending an enormous amount of time on a customer call, thereby impacting the customer experience. This is especially detrimental during peak business hours, when it is important to resolve issues quickly since there is typically a backlog of waiting calls. Wouldn’t it impress the customer if the CSR proactively asked, “Are you calling about the accessories that you bought yesterday?”, along with a warning that the order may be delayed. Informing the customer and providing a discount voucher or a different added benefit results in a much happier customer. The heart of this improved customer experience is the IBM Sterling Supply Chain Business Assistant With Watson™, which infuses conversational AI capabilities into the IBM Sterling Call Center and enables intelligent orchestration of customer transactions across back-end record systems. It also surfaces recommendations and best next steps based to enable quick and easy decision-making for the CSRs. The Sterling Supply Chain Business Assistant With Watson appears as a pop-up over the IBM Sterling Call Center application and can be embedded into any other application. Sample insights are shown below.

  • Scaling Persistent Volume Claims with Red Hat OpenShift Container Storage v4.2

    For choosing a storage solution for dynamic provisioning of persistent volume claims (PVC) in OpenShift Container Platform, the time it takes to bind and prepare a PVC for the use with application pods is a crucial factor. For Red Hat OpenShift Container Storage v4.2 we performed a series of tests investigating how OCP v4.2 behaves from a scalability point of view. We wanted to know how fast application pods are starting when PVCs are from different storage classes provided, and to get get numbers which can be used when making decisions when choosing storage solution for OCP application pods. The test results presented in this document are recommended values for OpenShift Container Storage v4.2 and do not show the real limits for Openshift Container Storage v4.2, which are higher. We will conduct more scalability tests for future OpenShift Container Storage releases. For future OpenShift Container Storage releases we plan to target configurations for cases when more pods are running on the OpenShift Container Platform cluster and are actively requesting PVCs originating from Openshift Container Storage. In this document we describe test processes and results gathered during PVC scale test execution with Openshift Container Storage v4.2 showing why OpenShift Container Storage is the supreme storage solution for use cases where pod density and PVC allocation speed are key, as e.g. in CI/CD environments.

Purges in Free Software

  • What is a safe space?

    When foreign people come along with a different, but no less valid, Code of Conduct, zealots start screaming out for the comfort of their safe space. That is how we get the hysteria that precipitated the Hanau shooting and the lynching of Polish workers in the UK in the name of Brexit. The Third Reich may have been the ultimate example of the search for a safe space: a safe space for the white Aryan race. Nazis really believed they were creating a safe space. Germans allowed the Nazis to rule, in the belief that they were supporting a safe space. The golden rule of a safe space is that it is only safe for some. As George Orwell puts it, All animals are equal, but some animals are more equal than others. Tolerance and safe spaces are mutually exclusive.

  • The right to be rude

    The historian Robert Conquest once wrote: “The behavior of any bureaucratic organization can best be understood by assuming that it is controlled by a secret cabal of its enemies.” Today I learned that the Open Source Initiative has reached that point of bureaucratization. I was kicked off their lists for being too rhetorically forceful in opposing certain recent attempts to subvert OSD clauses 5 and 6. This despite the fact that I had vocal support from multiple list members who thanked me for being willing to speak out. It shouldn’t be news to anyone that there is an effort afoot to change – I would say corrupt – the fundamental premises of the open souce culture. Instead of meritocracy and “show me the code”, we are now urged tpo behave so that no-one will ever feel uncomfortable. The effect – the intended effect, I should say, is to diminish the prestige and autonomy of people who do the work – write the code – in favor of self-appointed tone-policers. In the process, the freedom to speak necessary truths even when the manner in which they are expressed is unpleasant is being gradually strangled. And that is bad for us. Very bad. Both directly – it damages our self-correction process – and in its second-order effects. The habit of institutional tone policing, even when well-intentioned, too easily slides into the active censorship of disfavored views.
