Glimpse – A Fork of the GIMP

Filed under

Glimpse is a free and open-source image editor for easy-to-use expert level image manipulation. Its capabilities include transforming, cropping, and retouching photos, batch image processing, automated format conversions, and color balance correction.

Glimpse is based on the GNU Image Manipulation Program (GIMP) and built with the goal of experimenting with new ideas to expand the use of free software. A strong reason for the change in name from GIMP to Glimpse is to strip the software of all connotations that may be considered ableist and of its joke reference origin.

That notwithstanding, the Glimpse team has publicly expressed their interest in cooperating with the GNU Image Manipulation Program contributors and not competing with them. Even a portion of donations to Glimpse is passed on to the GIMP team to help facilitate progress.

Glimpse, therefore, features a major overhaul to GIMP with a new name and logo to complement a refurbished user interface. Other improvements in the latest version include the removal of unnecessary “fun” brushes, a rebranded “Gimpressionist” plug-in and text color picker, the credit of upstream contributors in the UI, a brand style overhaul and better non-English translations. Concerning customization, the ‘Gray’ UI theme and ‘Color’ icon pack are available.

The 10 Best Open-Source Video Editors

Filed under

Although mainstream video editors such as Adobe Premiere Pro, Final Cut Pro, and Filmora do get the job done (and that too, quite well), their subscription packages can cost an arm and a leg. Accordingly, it won’t be wrong to say that not everyone would be able to afford such pricey software. If you feel the same way, you’re in luck as there are plenty of free and open-source video editors out there, which you can not just free but also allows making changes as per your needs if you know a thing or two about coding.

GNOME and KDE: GUADEC, KDE Itinerary, GCompris and Kdenlive

  • Colin Walters: “Immutable” → reprovisionable, anti-hysteresis

    Why not "immutable"/"read-only"?

    Because it’s very misleading. These system as a whole is not immutable, or read-only, or stateless – there are writable, persistent data areas. And more importantly, those writable data areas allow persistently storing privileged code.

    Usually instead of talking about an "immutable" system that allows in place updates, it’d be more useful and accurate to say "image based".

    And this gets into another huge difference between traditional package managers and image based systems: The amount of "internal state".

    The way most package managers work is when you type $pkgmgr install foo, the fact that you want foo installed is recorded by adding it to the database. But the package manager database also includes a whole set of "base packages" that (usually) you didn’t choose. Those "base packages" might come from a base container when you podman/docker pull, for cloud images the default image, and physical systems they often come from a distribution-specific default list embedded/downloaded from the ISO or equivalent.

    A problem with this model then is "drift" – by default if the distribution decides to add a package to the base set by default, you (usually) don’t get it by default when applying in place updates since most package managers just update the set of packages you have. One solution to this is metapackages, but if not everything in the base is covered you still have drift that can be hard to notice over time.

  • Apoorv Sachan: My First GUADEC

    Finally, here it is! My "My First GUADEC" post. It’s been three months since I have been working on my GSoC project, and as the project itself and GSoC approach their final days, I would like to talk about my GUADEC experience. Ever since the GSoC results were announced, I had been aware of the fact that GSoC students, not only get to attend but also get an opportunity to present their work at the annual GNOME Conference called GUADEC, which brings together users and enthusiasts from all over the world. Words are not enough to express the kind of excitement I’ve had for attending this.


  • Virtual Conferences

    Probably the most obvious part of the evolution of virtual events is the clearly visible (and audible) quality improvements. A very welcome change especially for the larger events where you spent all day listening to people, and that can be quite exhausting if we don’t properly understand what’s being said and have to manually adjust audio levels for each speaker.

    The increased quality requirements also impacted my own setup, moving from built-in webcam and simple headset to full HD external camera, lapel microphone, proper lighting and OBS for scene composition, cleaning the audio feed and recording, with a virtual V4L webcam and a virtual PulseAudio microphone feeding this into the corresponding conference software. A bit too complex and fragile for my taste, but producing a much better result.


    The biggest gain provided by virtual events is the far far lower threshold for attending. No travel, much lower cost (if any), often not even a registration, you can just drop in and see if the event is interesting to you and you feel comfortable there before getting more involved.

    I noticed this was even the case for myself, and I’m not exactly facing a particular high threshold there, having attended many events during the past 15+ years, usually belonging to the majority demographic, having a passport that lets me travel easily to most parts of the world and having access to multiple travel expense funding sources. So I can only imagine this to be making a much larger difference for people not checking all those boxes.

    Since June I have tried to attend any conference or meetup I became aware of that is vaguely related to KDE Itinerary, not all of which I would have attended physically probably. Every single one however turned out to have been very much worth it, yielding concrete results for KDE Itinerary. If you follow the regular development summaries you will already have spotted a few of those, and there’s more to come.

Contributing to Open Source Projects without Coding Knowledge

Filed under

There’s lots of ways of contributing to open source projects.

A common misconception about contributing to open source is that you need to write code. In fact, it’s often the other parts of a project that are in urgent need of assistance. Other ways of helping an open source project include writing documentation, identifying bugs, testing code changes, answering queries from users, planning events, suggesting design improvements, perform user experience testing, making a monetary donation, and more.

I want to share a few of my recent experiences of contributing to open source projects.

  • Apple Blocks WordPress Updates to Force IAP Support
  • Apple Blocked Updates to Free WordPress App Until It Added In-App Purchases: Matt Mullenweg

    WordPress for iOS finally received a new update yesterday (August 21) after a period of almost a month. Turns out, the Automattic team that runs the app as well as popular blogging service was blocked by Apple from pushing new app updates as it was not offering an in-app purchase option for’s paid plans and domain purchases, the company’s founder and CEO Matt Mullenweg has revealed. The presence of in-app purchases in the WordPress app would allow Apple to take up to 30 percent cut of all revenue that the app generates using the in-app purchases.

  • WordPress founder claims Apple cut off updates to his completely free app because it wants 30 percent

    Now, WordPress founding developer Matt Mullenweg is accusing Apple of cutting off the ability to update that app — until or unless he adds in-app purchases so the most valuable company in the world can extract its 30 percent cut of the money.

  • Apple tells court it "wants Epic on iOS" but Fortnite "hotfix" turned into Epic Games' "hot mess": response to motion for emergency relief

    With respect to Epic's claim of suffering irreparable harm unless the court grants its motion, Apple's opposition brief is consistent with a statement it provided to The Verge a few days ago. The term "status quo" plays a central role here. The purpose of temporary relief is to prevent a party from changing a situation to the moving party's detriment in the absence of an injunction (a TRO is the fastest injunction, even more preliminary than what is called a preliminary injunction). Apple explains to the court that Epic's perspective on the status quo is, in reality, something else: the status quo would be for Epic to simply comply with Apple's App Store terms and policies, and with its developer agreement, while its antitrust complaint challenging those terms is pending. If, however, the court granted Epic's motion, it would allow Epic to get away with a breach of its contractual obligations. The requested TRO would not preserve the status quo. It would force Apple to modify its long-standing App Store terms.

    Another key term--in connection with any type of injunction--is "irreparable harm." Epic's motion for a TRO argued that the unavailability of Fortnite on the App Store and, as a further consequence of Epic's non-compliance, the termination of its developer agreement (which would prevent Epic from using Apple's developer tools in the further development not only of Epic's games but also of its Unreal Engine) would constitute irreparable harm. Apple's opposition brief dismisses that theory and distinguishes between irreparable harm on the one hand and "self-inflicted wounds" on the other hand. The Ninth Circuit, which is the appeals court for (among many others) the Northern District of California, stated earlier this year that "self-inflicted wounds are not irreparable injury," quoting earlier decisions in this circuit and in the Seventh Circuit.

  • Apple says Epic is ‘putting the entire App Store model at risk’

    In a declaration to the court, Apple executive Phil Schiller wrote that Epic CEO Tim Sweeney asked for a “special deal with only Epic” that would “fundamentally change the way in which Epic offers apps on Apple’s iOS platform.” When Apple declined, Epic changed its policies to cut Apple out of in-app purchases. Now, the company argues that Epic’s ban is its own responsibility.

  • Xcode becomes vector for new Mac malware attack

    We’ve seen a similar attack before. The so-called "XCode Ghost" was a malware-infested version of Apple’s developer environment that was distributed outside of Apple’s channels. Apps built using the software were preinstalled with malware.

    While security researchers were rightly concerned about XCode Ghost, the problem was quickly curtailed as Apple used the moment to stress the need to download critical files only from bona fide App Stores. It is much easier to subvert systems via poorly secured third-party app stores, and security is part of what we pay for when we purchase an app.

  • Start contributing to open source Call for Code projects

    Jumping into the open source world can be intimidating for the uninitiated. Don’t let fear of the unknown stop you from getting involved in open source. In this blog post, we cover some of the basics you need to know before contributing your first line of code. [...] Now that you understand that basic gist of open source, let’s go a little deeper. While some open source projects are small developer tools that help you accomplish a single task, other open source projects are large, complicated pieces of software that have interconnected parts. In these larger projects, different teams or working groups focus on developing specific parts of the technology, collaborating on the technology, peer reviewing and testing the code, and contributing their changes to the core tech.

  • Build Smart on Kubernetes World Tour: Developers’ path to platform freedom

    Without a doubt, Kubernetes is one of hottest open tech projects today and has been so for many years now. The reason for its durable, not-so-secret success? It’s the ability to containerize code, which frees developers from the constraint of writing code for one platform only and instead gives you the freedom of write-once, deploy-anywhere development. And why is this important? Enterprises know that the fastest route to app modernization depends on the ability to develop solutions that protect current tech investments, which likely run across multiple cloud platforms on and off premises. In other words, success depends on your ability to build solutions once and deploy them across multiple hybrid cloud platforms. Yep, containers tech delivers all of that and more. With that baseline, I’m writing to let you know that when it comes to learning Kubernetes, the IBM Developer advocates team has you completely covered with the Build Smart on Kubernetes World Tour. Since we launched the World Tour back in the fall of 2019, the team has delivered literally hundreds of free hands-on workshops globally to teach developers about the power of Kubernetes. It’s all part of the IBM Developer Way, delivering on our sole mission to teach the world’s developers about open tech through hands-on workshops and supporting content such as blog posts, tutorials, and videos. With the recent launch of new content on the Build Smart on Kubernetes World Tour site, it feels like a good time to provide a quick virtual tour of all that the site offers. Visit the updated site to find more than just upcoming tour events, but also self-paced learning options. You can now choose whether you learn at your own pace by viewing recorded content, register for upcoming live events, or, even better, both. I’m going to review each section to show you the details.
