  • Lightworks 14.5 Video Editor Released With Same-Day Linux Support But Still No Source

    Lightworks, the long-standing non-linear video editing system that has offered a native Linux build the past few years after being challenged by delays for a few years, is out today with version 14.5 and comes with Linux, macOS, and Windows support.

    Lightworks 14.5 succeeds the Lightworks 14.0 release from a year and a half ago as the latest major update for this cross-platform software owned by EditShare. This new release has user-interface improvements, variable frame-rate media support, higher GPU precision settings, Reaper export support, AC-3 audio support in various formats, support for Blackmagic RAW files, and a variety of other enhancements.

  • Carnegie Mellon is Saving Old Software from Oblivion

    In early 2010, Harvard economists Carmen Reinhart and Kenneth Rogoff published an analysis of economic data from many countries and concluded that when debt levels exceed 90 percent of gross national product, a nation’s economic growth is threatened. With debt that high, expect growth to become negative, they argued.

    This analysis was done shortly after the 2008 recession, so it had enormous relevance to policymakers, many of whom were promoting high levels of debt spending in the interest of stimulating their nations’ economies. At the same time, conservative politicians, such as Olli Rehn, then an EU commissioner, and U.S. congressman Paul Ryan, used Reinhart and Rogoff’s findings to argue for fiscal austerity.

8 of the Best Free Linux Comic Book Viewers (Updated 2018)

Filed under
Software

A comic book is a magazine which consists of narrative artwork in the form of sequential images with text that represent individual scenes. Panels are often accompanied by brief descriptive prose and written narrative, usually dialog contained in word balloons emblematic of the comics art form. Comics are used to tell a story, and are published in a number of different formats including comic strips, comic books, webcomics, Manga, and graphic novels. Some comics have been published in a tabloid form. The largest comic book market is Japan.

Many users associate desktop Linux with their daily repetitive grind. However, we are always on the look out for applications that help make Linux fun to use. It really is a great platform for entertainment.

Some document viewers offer a good range of different formats. Although they are not dedicated comic book viewers, Evince and okular have support for the common comic book archive files, and merit mention here.

  • Excellent Free DICOM Viewers – Medical Imaging Software

    DICOM (an acronym for Digital Imaging and Communications in Medicine) is a worldwide standard in Health IT and is provided by the National Electrical Manufacturers Assocation (NEMA). It’s the standard open image format used to handle, store, print and transmit information in medical imaging. This standard specifies the way medical images and metadata like study or patient related data are stored and communicated over different digital medias.

    DICOM is a binary protocol and data format. The binary protocol specifies a set of networking protocols, the syntax and specification of commands that can be exchanged with these protocols, and a set of media storage services. It’s an entire specification of the elements required to achieve a practical level of automatic interoperability between biomedical imaging computer systems—from application layer to bit-stream encoding.

    DICOM files can be exchanged between two entities that are capable of receiving image and patient data in DICOM format.

  • Encrypted Evernote Alternative Turtl v0.7 Includes Rewritten Server, New Spaces Feature

    Turtl was updated to version 0.7 yesterday, the new release shipping with a rewritten server, among other changes. I'll cover the new version in the second part of this article, after an introduction to Turtl.

    Turtl is a "secure, encrypted Evernote alternative". The free and open source tool, which is considered beta software, can be used to take notes, save bookmarks, store documents and images, and anything else you may need, in a safe place.

    There are Turtl applications available for Linux, Windows, macOS and Android, while an iOS application should also be available in the future. Chrome and Firefox extensions are available to easily bookmark the page you're on, great for quickly saving sites for later.

    The Turtl developers offer the service (hosted server) for free, but a premium service is planned for the future. However, the Turtl server is free and open source software, so you can install and use your own instance.

  • Rancher Takes on Multicloud Kubernetes Management

    One thing that happens over time is that organizations can end up with multiple deployments in different places, something that is commonly referred to as - multicloud. It's a deployment challenge that Rancher Labs has built it namesake Rancher cloud orchestration platform to help enable.

    [...]

    With the multicloud world, Williams said its critically important to put in place all of the policy and user management that is needed to have a consistent approach across disparate Kubernetes deployments.

    Rancher is now and has always been open source software that is entirely free for any organization to use. Rancher Labs charges for commercial support, which Williams said is a stable and growing business. He said that Rancher Labs has both outbound sales people as well as channel relationships and today has over 200 customers.

    "But that's a pretty small percentage of the total of 10,000 companies use Rancher everyday to run their containers," he said.

    Williams said that Rancher is Kubernetes, with Docker containers and a management plane and it's something that larger organizations really care about once those services are in production.

  • Taking notes with Laverna, a web-based information organizer

    I don’t know anyone who doesn’t take notes. Most of the people I know use an online note-taking application like Evernote, Simplenote, or Google Keep.

    All of those are good tools, but they’re proprietary. And you have to wonder about the privacy of your information—especially in light of Evernote’s great privacy flip-flop of 2016. If you want more control over your notes and your data, you need to turn to an open source tool—preferably one that you can host yourself.

    And there are a number of good open source alternatives to Evernote. One of these is Laverna. Let’s take a look at it.

  • Essential System Tools: gtop – System monitoring dashboard for the terminal

    This is the second in our series of articles highlighting essential system tools. These are small utilities, useful for system administrators as well as regular users of Linux based systems. The series examines both graphical and text based open source utilities.

    We previously covered ps_mem, a really useful memory utility. This time, another console utility is under the spotlight. It’s called gtop.

    gtop is an open source system monitoring utility written in JavaScript. Our Group Test covered alternatives to top. In particular, htop is a remarkable system monitoring tool. gtop receives far less exposure than htop, but deserves more publicity. Why? Let’s see.

  • Good Alternatives To Man Pages Every Linux User Needs To Know

    A man page, acronym of manual page, is a software documentation found in all Unix-like operating systems. Some man pages are short; some are comprehensive. A man page is divided into several parts, organized  with headings for each section, such as NAME, SYNOPSIS, CONFIGURATION, DESCRIPTION, OPTIONS, EXIT STATUS, RETURN VALUE, ERRORS, ENVIRONMENT, FILES, VERSIONS, CONFORMING TO, NOTES, BUGS, EXAMPLE, AUTHORS, and SEE ALSO.

    Sometimes, I find it really time-consuming when I wanted to learn a practical example of a given Unix command using man pages. So, I started to look for some good alternatives to man pages which are focused on mostly examples, skipping all other comprehensive text parts. Thankfully, there are some really good alternatives out there. In this tutorial, we will be discussing 4 alternatives to man pages for Unix-like operating systems.

  • KeeWeb – An Open Source, Cross Platform Password Manager

    If you’ve been using the internet for any amount of time, chances are, you have a lot of accounts on a lot of websites. All of those accounts must have passwords, and you have to remember all those passwords. Either that, or write them down somewhere. Writing down passwords on paper may not be secure, and remembering them won’t be practically possible if you have more than a few passwords. This is why Password Managers have exploded in popularity in the last few years. A password Manager is like a central repository where you store all your passwords for all your accounts, and you lock it with a master password. With this approach, the only thing you need to remember is the Master password.

    On Saturday, the first people started to arrive for this autumn’s Krita development sprint. It’s also the last week of the fundraiser: we’re almost at 5 months of bug fixing funded! All in all, 8 people are here: Boudewijn, the maintainer, Dmitry, whose work is being sponsored by the Krita Foundation through this fundraiser, Wolthera, who works on the manual, videos, code, scripting, Ivan, who did the brush vectorization Google Summer of Code project this year, Jouni, who implemented the animation plugin, session management and the reference images tool, Emmet and Eoin who started hacking on Krita a short while ago, and who have worked on the blending color picker and kinetic scrolling.

  • scikit-survival 0.6.0 released

    Today, I released scikit-survival 0.6.0. This release is long overdue and adds support for NumPy 1.14 and pandas up to 0.23. In addition, the new class sksurv.util.Surv makes it easier to construct a structured array from NumPy arrays, lists, or a pandas data frame. The examples below showcase how to create a structured array for the dependent variable.

  • RcppCCTZ 0.2.4

    RcppCCTZ uses Rcpp to bring CCTZ to R. CCTZ is a C++ library for translating between absolute and civil times using the rules of a time zone. In fact, it is two libraries. One for dealing with civil time: human-readable dates and times, and one for converting between between absolute and civil times via time zones. And while CCTZ is made by Google(rs), it is not an official Google product. The RcppCCTZ page has a few usage examples and details. This package was the first CRAN package to use CCTZ; by now at least two others do—but decided in their infinite wisdom to copy the sources yet again into their packages. Sigh.

  • Weblate 3.2

  • How an affordable open source eye tracker is helping thousands communicate
    In 2015, while sat in a meeting at his full-time job, Julius Sweetland posted to Reddit about a project he had quietly been working on for years, that would help people with motor neurone disease communicate using just their eyes and an application. He forgot about the post for a couple of hours before friends messaged him to say he'd made the front page. Now three years on Optikey, the open source eye-tracking communication tool, is being used by thousands of people, largely through word of mouth recommendations. Sweetland was speaking at GitHub Universe at the Palace of Fine Art in San Francisco, and he took some time to speak with Techworld about the project. [...] Originally, Sweetland's exposure to open source had largely been through the consumption of tools such as the GIMP. "I knew of the concept, I didn't really know how the nuts and bolts worked, I was always a little blase about how do you make money from something like that... but flipping it around again I'm still coming from the point of view that there's no money in my product, so I still don't understand how people make money in open source...

    Even new programmers can provide a lot of value with their code reviews. You don't have to be a Rockstar Ninja 10x Unicorn Diva programmer with years and years of experience to have valuable insights. In fact, you don't even have to be a programmer at all. You just have to be knowledgable enough to spot patterns. While you won't be able to do a complete review without programming knowledge, you may still spot things that could use some work or clarification. If you're not a Rockstar Ninja 10x Unicorn Diva programmer, not only is your code review feedback still valuable, but you can also learn a great deal in the process: Code layout, programming style, domain knowledge, best practices, neat little programming tricks you'd not have seen otherwise, and sometimes antipatterns (or "how not to do things"). So don't let the fact that you're unfamiliar with the code, the project, or the language hold you back from reviewing code contributions. Give it a go and see what there is to learn and discover.
