To-Do App With Built In Timer "Go For It!" Updated With Pomodoro Timer, Configurable Shortcuts

Filed under
Software

Go For It! productivity application has been updated to version 1.8.0. The new release adds Pomodoro timer mode, configurable keyboard shortcuts, an option to log the time spent working on a task to the todo.txt files, and more.

Go For It! is a Gtk tool which includes a to-do list and a timer. It uses the Todo.txt format, which is supported by a plethora of applications, for both desktops and mobile devices; Todo.txt is a popular to-do list format in which the data is stored in a flat text file. The application is available for Windows and Linux.

The most important change in the latest Go For It! 1.8.0 is a new option to change the timer mode. The time break time or time between breaks doesn't have to be the same anymore - you can now set the timer mode to Simple, Pomodoro, or use a custom time schedule.

Arc Menu 47 Released with New Layout, Other Improvements

Filed under
GNOME

A new version of Arc Menu, the popular app launcher extension for GNOME Shell, is now available to download.

Arc Menu v47 includes a new menu layout (called “Tognee”, and pictured above), adds the option to rank installed software in alphabetical order (very handy), and introduces a new (and entirely opt-in) “frequent apps” view.

Mouse scrolling and keyboard navigation is said to be improved in this release; application context menus and tooltips boast better contrast; and there are new preset themes.

The icon picker, which lets you set a different menu icon, boasts some UI tweaks to make sifting through and finding glyphs a touch faster and saner. A selection of new panel icons are also said to be available include an openSUSE icon.

Also look out for new “Flip Layout Horizontally” and “Searchbar Location” options available in traditional panel layouts.

Finally, Arc Menu 47 requires GNOME 3.36. You can continue to use older versions of the menu on GNOME 3.34 and earlier, you just won’t get all of the ‘new’ stuff mentioned in this roundup.

The demo also showcases Monado's ability to deal with multiple graphics APIs as Blender uses OpenGL and xrgears Vulkan to submit its frames.

    To enable the extension in xrgears only this small change was required, which enables the XR_EXTX_overlay extension and passes the XrSessionCreateInfoOverlayEXTX struct to the graphics bindings `next` field.

    As the readers of this blog almost surely know, I'm the author of NoScript, a web browser security enhancer which can be installed on Firefox and Chrome, and comes built-in with the Tor Browser.

    NoScript has received support by the Open Technology Fund (OTF) for specific development efforts: especially, to make it cross-browser, better internationalized and ultimately serving a wider range of users.

    OTF's mission is supporting technology to counter surveillance and censorship by repressive regimes and foster Internet Freedom. One critical and strict requirement, for OTF to fund or otherwise help software projects, is them being licensed as Free/Libre Open Source Software (FLOSS), i.e. their code being publicly available for inspection, modification and reuse by anyone. Among the successful projects funded by OTF, you may know or use Signal, Tor, Let's Encrypt, Tails, QubeOS, Wireshark, OONI, GlobaLeaks, and millions of users all around the world, no matter their political views, trust them because they are FLOSS, making vulnerabilities and even intentionally malicious code harder to hide.

Meet UbuntuEd 20.04, an Educational Ubuntu Flavor for Kids, Schools and Universities

Filed under
Ubuntu

The team behind the Ubuntu Unity distribution have released today UbuntuEd 20.04, an unofficial, educational focused Ubuntu flavor for kids, schools and universities.

Meet UbuntuEd, an educational edition of Ubuntu Linux created by Rudra Saraswat, the same person who created Ubuntu Unity, and designed as a substitute for the discontinued Edubuntu flavor.

The first release of UbuntuEd is now available, based on Ubuntu 20.04 LTS (Focal Fossa) and featuring both GNOME and Unity7 desktop environments. In other words, you’re getting Ubuntu, Ubuntu Unity and Ubuntu Education in a single container.

Users will be able to choose the right desktop environment for them, GNOME or Unity7, from the login screen. However, it looks like Unity7 is the default session when booting the live system and after the installation.

As expected, UbuntuEd comes with a plethora of educational apps for kids, schools and universities. Four metapackages are also available for those who want to install additional educational apps if they need more. Moreover, it’s possible to install these metapackages on your existing Ubuntu systems.

Sans Investigative Forensics Toolkit (SIFT)

Filed under
GNU
Linux

SIFT is a computer forensics distribution created by the SANS Forensics team for performing digital forensics. This distro includes most tools required for digital forensics analysis and incident response examinations. SIFT is open-source and publicly available for free on the internet. In today’s digital world, where crimes are committed every day using digital technology, attackers are becoming more and more stealthy and sophisticated. This can cause companies to lose important data, with millions of users exposed. Protecting your organization from these attacks requires strong forensic techniques and knowledge in your defense strategy. SIFT provides forensic tools for file systems, memory and network investigations to perform in-depth forensic investigations.
In 2007, SIFT was available for download and was hard coded, so whenever an update arrived, users had to download the newer version. With further innovation in 2014, SIFT became available as a robust package on Ubuntu, and can now be downloaded as a workstation. Later, in 2017, a version of SIFT came to market allowing greater functionality and providing users the ability to leverage data from other sources. This newer version contains more than 200 tools from third parties, and contains a package manager requiring users to type only one command to install a package. This version is more stable, more efficient, and provides better functionality in terms of memory analysis. SIFT is scriptable, meaning that users can combine certain commands to make it work according to their needs.

SIFT can run on any system running on Ubuntu or Windows OS. SIFT supports various evidence formats, including AFF, E01, and raw format (DD). Memory forensics images are also compatible with SIFT. For file systems, SIFT supports ext2, ext3 for linux, HFS for Mac and FAT, V-FAT, MS-DOS, and NTFS for Windows.

  • Making open source more inclusive by eradicating problematic language

    Open source has always been about differing voices coming together to share ideas, iterate, challenge the status quo, solve problems, and innovate quickly. That ethos is rooted in inclusion and the opportunity for everyone to meaningfully contribute, and open source technology is better because of the diverse perspectives and experiences that are represented in its communities. Red Hat is fortunate to be able to see the impact of this collaboration daily, and this is why our business has also always been rooted in these values.

    Like so many others, Red Hatters have been coming together the last few weeks to talk about ongoing systemic injustice and racism. I’m personally thankful to Red Hat’s D+I communities for creating awareness and opportunities for Red Hatters to listen in order to learn, and I’m grateful that so many Red Hatters are taking those opportunities to seek understanding.

  • Kourier: A lightweight Knative Serving ingress

    Until recently, Knative Serving used Istio as its default networking component for handling external cluster traffic and service-to-service communication. Istio is a great service mesh solution, but it can add unwanted complexity and resource use to your cluster if you don’t need it.

    That’s why we created Kourier: To simplify the ingress side of Knative Serving. Knative recently adopted Kourier, so it is now a part of the Knative family! This article introduces Kourier and gets you started with using it as a simpler, more lightweight way to expose Knative applications to an external network.

    Let’s begin with a brief overview of Knative and Knative Serving.

  • CodeTheCurve: A blockchain-based supply chain solution to address PPE shortages

    This past April, creative techies from all over the world gathered online for CodeTheCurve, a five-day virtual hackathon organized by the United Nations Educational, Scientific, and Cultural Organization (UNESCO) in partnership with IBM and SAP. Participants all worked toward the goal of creating digital solutions to address the global pandemic.

    Our team focused on the goal of improving the efficiency of the personal protective equipment (PPE) supply chain in order to prevent shortages for health care workers. With the rise of the current global pandemic, supplies of medical equipment have become more critical, particularly PPE for medical workers. In many places, PPE shortages have been a serious problem. To address this challenge, we proposed that a blockchain-based supply chain could help make this process faster and more reliable, thereby connecting health ministries, hospitals, producers, and banks, and making it easier to track and report information on supplies.

  • Analyze your Spark application using explain

    It is important that you have some understanding of Spark execution plan when you are optimizing your Spark applications. Spark provides an explain API to look at the Spark execution plan for your Spark SQL query. In this blog, I will show you how to get the Spark query plan using the explain API so you can debug and analyze your Apache Spark application. The explain API is available on the Dataset API. You can use it to know what execution plan Spark will use for your Spark query without actually running it. Spark also provides a Spark UI where you can view the execution plan and other details when the job is running. For Spark jobs that have finished running, you can view the Spark plan that was used if you have the Spark history server set up and enabled on your cluster. This is useful when tuning your Spark jobs for performance optimizations.

Shout out to @fedora on Telegram. They’re nice, wholesome and helpful. They also got me into self-hosting and basic sys-admin stuff.

  • Fedora Looking To Offer Better Upstream Solution For Hiding/Showing GRUB Menu

    Fedora for the past few releases doesn't show the GRUB boot-loader menu by default when only Fedora is installed on the system as there is little purpose for most users and it just interrupts the boot flow. But for those wanting to access the GRUB bootloader menu on reboot, they offer integration in GNOME to easily reboot into this menu. The other exception is the menu will be shown if the previous boot failed. This functionality has relied on downstream patches but now they are working towards a better upstream solution.

    Hans de Goede of Red Hat who led the original GRUB hidden boot menu functionality is looking to clean up this feature for Fedora 33. The hope is to get the relevant bits upstream into GNOME and systemd for avoiding the downstream patches they have been carrying. This reduces their technical debt and also makes it easier for other distributions to provide similar functionality.

  • Fedora Developers Discussing Possibility Of Dropping Legacy BIOS Support

  • Ingo Juergensmann: Migrating from Drupal to WordPress

    If you can read this on planet.debian.org then migrating my blog from Drupal to WordPress was successful and the feed has been successfully changed by the Debian Planet Maintainers (thanks!). I’ve been a long term Drupal user. I think I started to use Drupal since it was included in Debian. At some point Drupal was removed from Debian and I started to use Serendipity instead. Later Drupal was included in Debian again and I moved back to Drupal. I think this must have been around Drupal 4 or Drupal 5. No idea. I even became active in the Drupal community and went to one of the first Drupal barcamps in Germany, namely in Cologne. This was shortly before Dries Buytaert started a business off of Drupal and went to the USA. I met with many devs of Drupal in Cologne and enjoyed the community and started with others a local Drupal User Group in Rostock. [...] So, after all the years my Drupal journey will come to an end. It was a long time with you. Sometimes joyful, sometimes painful. I wish you all the best, Drupal!

  • Red Kubes Container Platform Flies Open Source Flag

    Red Kubes, a Dutch-based startup, open sourced a free community edition of its Otomi Container Platform in a bid to remedy the ongoing complexity surrounding Kubernetes configurations. The scalability, agility, and speed-to-market advantages that Kubernetes offers have been handsome enough to capture a growing share of the enterprise market, but this very strength can become an Achilles heel for container deployments. In this sense, it’s far too easy – and common – to create thousands or even tens of thousands of containers across applications. Not only does this create an operational money pit, but management becomes a herculean feat to any container newbie.

  • Shots fired in disputes over OSS-as-a-Service

    Cloud services are the great disruptor of both IT organizations and vendors, and wrapping open source software around a service is the latest flashpoint. The open source development model has proven to be an incredible incubator of innovative software by democratizing and distributing the conception, design, implementation and debugging of new titles, advantages that were thoroughly explored more than two decades ago in the book, The Cathedral and the Bazaar. Although open source has since been adopted, encouraged and sponsored by every major software company, its origins were decidedly non-commercial with utopian overtones of liberating code from the tyranny of proprietary shackles. The earliest open source projects, notably Gnu Emacs and other tools from the Gnu Project, embraced this idealistic ethos with a restrictive, comprehensive license, GPL, that applies to derivative work using the code.

  • ROC and Precision-Recall curves - How do they compare?

    Both curves offer two useful information: how to choose the positive class prediction threshold and what is the overall performance of the classification model. The former is determined by selecting the threshold which yield the best tradeoff, in adequation with the prediction task and operational needs. The latter is done by measuring the area under the curves which informs about how good the model is, because by measuring the area under the curves, one computes the overall probability that a sample from the negative class has a lower probability than a sample from the positive class. With scikit-learn, the values can be computed either by using the roc_auc attribute of the object returned by plot_roc_curve() or by calling roc_auc_score() directly for ROC curves and by using the average_precision attribute of the object returned by plot_precision_recall_curve() or by calling average_precision_score() directly for PR curves.

Open Hardware: Raspberry Pi, Arduino, Thomas Petazzoni (Bootlin) on Training

  • Qsync fixed on the Pi4 and FF compiled

    The Raspberry Pi4 does not have a hardware battery-backed clock, so relies on getting the date and time from an Internet time server. In EasyOS, Qsync is the utility that does that. At first bootup, QuickSetup has a checkbox to enable getting time from the Internet, which will launch Qsync. At first bootup on the Pi4, if you are going to connect to Internet via wifi, not ethernet, then there won't be an immediate Internet access. No problem, Qsync will run once the Internet connection is established. Qsync will run just once at bootup and after Internet connection. That's fine, but I couldn't understand why it would suddenly stop working. Then discovered that /etc/init.d/qsync was getting its executable-flag cleared.
