Announcing notqmail

Software

Okay, that’s not entirely true. While qmail hasn’t been updated by its original author, a group of respected users created netqmail, a series of tiny updates that were informed, conservative, and careful. By their design, it was safe for everyone running qmail to follow netqmail, so everyone did. But larger changes in the world of email — authentication, encryption, and ever-shifting anti-spam techniques — remained as puzzles for each qmail administrator to solve in their own way. And netqmail hasn’t been updated since 2007.

7 Great Linux Statistical Analysis Tools

Software
Sci/Tech

Science is the effort of seeking to comprehend how the physical world works. From observation and experimentation, science uses physical evidence of natural phenomena to compile data and analyze the collated information.

In modern research it is essential for scientists to keep abreast of the latest statistical software. Just like the fast moving world of research, developments in statistical software and methods continue to abound. Making full use of the improvements in computer software helps to advance the pace of research.

Science really prospers and advances when individuals share the results of their experiments with others in the scientific community. There is a certain logic that scientific software should therefore be released in a freely distributable environment.

Linux is particularly strong in the field of open source statistical software. The purpose of this article is to identify software for performing statistical analysis. This type of software helps to summarize data in a shorter form, and helps scientists understand a concept or representation and make possible predictions based on this understanding.

  • Pause Music When Locking The Screen And Resume On Unlock For Spotify, Rhythmbox, Others

    When you lock your computer screen (without suspending the system), most desktop audio players continue playback in the background, sometimes not emitting any sound ¹. Due to this you may unintentionally skip parts of podcasts or songs in a playlist, etc.

    Enter pause-on-lock, a Bash script that pauses your music player when you lock the screen and resumes playback once the screen is unlocked.

    pause-on-lock works on Unity, GNOME, Cinnamon and MATE desktop environments, and by default it supports Spotify and Rhythmbox. With the help of playerctl (a command line controller for controlling media players that support the MPRIS D-Bus interface), this script can extend its supported music players to many others, including Audacious, VLC, Cmus, and others.

  • Easy Way to Screen Mirroring Android on Ubuntu!

    Screen Mirroring is one of the features found on smartphones, one of which is on Android. This feature serves to display the smartphone to a computer. This is very useful for example when used for demo applications that you make, or maybe for other things related to smartphones.

    In Ubuntu, we can do screen mirroring with applications available on Android, for example is AirDroid which can be used for screen mirroring through a browser. But I feel less optimal when using this instant method.

    Because there is a lag between activity on the smartphone and on the monitor screen on the computer, and the results are less than optimal. What might be the cause because it is opened through a browser and uses wi-fi? (Personal question).

    I am looking for another application for screen mirroring on Ubuntu, and one of the very good applications is Scrcpy. This application can be used for screen mirroring without a root device.

(The first attempt does not correctly mount the backup partition; the second attempt always succeeds).

    Geofencing is the use of GPS or radio-frequency identification technology to create a virtual geographic boundary, enabling software to trigger a response when a mobile device enters or leaves a particular area or, in the case of the Rave Panic Button app, to pinpoint a caller's exact location through a virtual map of the campus.
     

                         

    "When there is an incident on campus and (the authorized user) activates one of the five panic buttons," French said, "it immediately sends a text, email, and an in-app notification providing situational awareness to all the other staff members on campus. It then provides a direct dial into the 911 dispatch center."

Who loves eye candy? Don’t be shy — you can raise both hands!!

Linux Candy is a new series of articles covering interesting eye candy software. We’re only going to feature open-source software in this series.

I’m not going to harp on about the tired proverb “All work and no play makes Jack a dull boy”. But there’s a certain element of truth here. If you spend all day coding neural networks, mastering a new programming language, sit in meetings feeling bored witless, you’ll need some relief at the end of the day. And what better way by making your desktop environment a bit more memorable.

Let’s start our candy adventure with WallGen. It’s a small command-line utility that generates HQ poly wallpapers with only a few text arguments for inputs. Depending on these arguments, you can create shape-based patterns, randomly filled surfaces, and even image-based patterns.

Programming: OpenPOWER Foundation, iOS and Android Localization Tool, First Python Program, Eclipse Vert.x Spring Boot

  • Open Source Developer Gain New Collaboration Opportunities on Open Hardware

    Live from Open Source Summit this week, we’re thrilled to share that the OpenPOWER Foundation is becoming a project hosted at The Linux Foundation. This includes a technical contribution of the POWER Instruction Set Architecture (ISA) and Source Design Implementations, including a softcore implementation of the POWER ISA. The OpenPOWER Foundation recognizes how increased collaboration across the open source ecosystem will advance open hardware technology and accelerate opportunity. Six years ago, IBM setup the OpenPOWER Foundation to widen the reach of their POWER technology. The goal from the start was to support Instruction Set Architecture and contributed Source Design Implementations required for data-driven HPC workloads like modelling and simulation, cloud services and also Artificial Intelligence (AI).

  • iOS and Android Localization Tool

    Localization is simply the process of translating your app into multiple languages. In situation like you need support multiple language, including API response messages and dynamic strings you need a list of localizable .strings file, and you need to localized it based on the Language you want ( e.g English, Chinese, Japanese ). Xcode has a built-in localizable file generator that generate your localizable .strings for each language you supported.

  • First Python Program

    Ok, really thrilled today. Patting myself on the back. I finally managed to write a program all on my ownsome. Kushal gave me a toy problem and I went around, scratched my head, did a lot of searching, a lot more headbanging, even more mistakes and then finally managed to write this. Am happy because this is how I imagined myself learning in the first place. Figuring out a problem someone has and then figuring out how to help them.

  • Reactive Spring Boot programming with Vert.x

    The latest bundle of Red Hat supported Spring Boot starters was recently released. In addition to supporting the popular Red Hat products for our Spring Boot customers, the Red Hat Spring Boot team was also busy creating new ones. The most recent technical preview added is a group of Eclipse Vert.x Spring Boot starters, which provide a Spring-native vocabulary for the popular JVM reactive toolkit. Let’s quickly go through the main concepts to get everybody on the same page before looking into an example. A reactive system as defined in the Reactive Manifesto is responsive, resilient, elastic, and message-driven. These properties guarantee easy replication, non-blocking communication with high system resources utilization and great fault tolerance. At the latest stage of software evolution, with cloud-first, low-latency, and highly data-intensive applications, reactive systems provide a great value for money. In our newest release, we have introduced a few Spring WebFlux extensions for Vert.x. With these extensions, you can build your application the way you’re used to—using WebFlux and Project Reactor—while network communications will be handled by the Vert.x servers and clients.
