DevOps is at the center of GitLab

Noutați

Accelerating DevOps adoption is core to achieving our mission of allowing everyone to contribute. DevOps enables contribution and collaboration between disparate and previously siloed teams. In fact, DevOps is so central to GitLab that we have incorporated the DevOps infinity loop into our logo. I’m excited to share our new logo and look with you. Building the One DevOps Platform DevOps has come a long way since GitLab was incorporated in 2014. And DevOps strategies are continuing to evolve. For some companies, each team selects their own DevOps tools, which causes problems when teams try to collaborate. For other companies, they select a set of preferred tools. But then they still require a lot of custom work to integrate DevOps point solutions together into a “Do It Yourself DevOps” solution. The more point solutions that are digitally duct taped together, the harder it is to integrate and maintain them all. And that’s why I’m proud that GitLab allows companies to do away with the many point solutions that have been digitally duct taped together and instead bring all DevOps functionalities together in ONE place. As someone who is passionate about single sources of truth for information, the concept of One resonates with me. There are many ways in which GitLab as The One DevOps Platform helps customers evolve their DevOps landscape and deliver better results for their organizations. One interface One data model One permissions model One value stream One set of reports One spot to secure your code One location to deploy to any cloud One place for everyone to contribute One. Platform. Today, all companies live and die on their ability to create and deliver software. This is true for every type of organization, from the largest global commercial enterprises to the emerging hypergrowth startups. That is why companies such as Siemens, T-Mobile, and UBS, have selected GitLab as their DevOps platform. “Having the ability to fully develop software in the cloud through GitLab is a game changer, allowing us to accelerate our tech strategy and offer a best-in-class engineering experience. It also means we’re able to constantly develop, test and deploy technical solutions while they are running, improving time-to-market for our clients while decreasing costs.” – Mike Dargan, Chief Digital and Information Officer at UBS. Evolving the GitLab brand, iterating our logo and look Iteration is deeply ingrained in our values. We strive to do the smallest thing possible to get to the best result as quickly as possible. This value leads to quicker learning and tighter feedback loops. I see this moment both as a symbol of GitLab’s growth and of the evolution of DevOps itself. To reinforce this moment, we are also evolving our logo. The new logo places GitLab at the center of the DevOps infinity loop. I am pleased that we chose to iterate instead of a step change – staying true to our values. And we’re just getting started I aspire for GitLab to represent a place where we elevate others through knowledge access, job access, and The One DevOps platform. More to come later this year as we work to help individuals elevate their careers by learning core DevOps principles and how to use GitLab. Thank you to our amazing customers for choosing GitLab as your One DevOps Platform. Most importantly, […]

The Next Big Thing In Python GUI

Delphi

Python is an extremely popular and adaptable programming language. Python’s ease of set-up, low learning curve, and low cost of entry has probably helped fuel an increased interest in coding and programming. The Python language has consistently grown in popularity among programmers since its inception, for the same reasons that learners love it but also because of its comprehensive versatility. The large number of capabilities combined with the low barrier to entry allows developers to quickly get up to speed and compete in the marketplace. Python is flexible and can work with a variety of programming paradigms. To be truly competitive, developers should become familiar with a variety of Python tools, libraries and IDEs in order to get the most out of Python and improve their skills. There are numerous development frameworks and packages available to assist you in creating aesthetically pleasing GUIs for your Python applications. Many can come with a fair number of compromises and sacrifices. Experienced developers recommend picking technology which adds value, enhances the development chain, and adds depth to this rich development language, such as Delphi’s Python tools. Adopting this technology allows you to take advantage of libraries that make the development process easier and aid in the creation of memorable user interfaces. In this article, we’ll look at the next big thing in Python GUI by discussing our thoughts on what we think is the best Python IDE and libraries out there. How is PyScripter helpful in creating a Python GUI? PyScripter began as a lightweight IDE with the purpose of offering a solid scripting solution for Delphi applications to complement the excellent Python for Delphi (P4D) components. It has a modern user interface and is only available for Microsoft Windows operating systems at the moment. It’s faster than some of the other IDEs because it’s developed in a compiled language rather than an interpreted one, and it includes a wide range of features that make it a useful Python programming environment. All the professional IDE capabilities such as brace highlighting, code folding, code completion, and syntax checking as you type are all aspects of PyScripter. It also supports the kind of features you’d expect to find in a proper native apps such as the ability to drag and drop files from Explorer into the PyScripter IDE, all of which add up to saving you time and making the development process a smooth and pleasurable experience. Why is PyScripter the best IDE for writing and debugging Python programs? PyScripter has a Python interpreter built-in that provides call indications and code completion. This program keeps track of your command history and lets you run scripts without having to save them. This IDE also includes a remote Python debugger for debugging Python code. Variables, the watch window, and the call stack may be seen as a result. Debugging can also be aided by conditional breakpoints or thread debugging. In circumstances where the programmer is unable to discover the fault in his code, debugger indications are also useful. You can not only destroy your files without saving them, but you can also debug them without saving them, which is a useful feature. What is Python4Delphi? Consider combining the power of Delphi’s GUI and desktop app development with Python in your applications to provide world-class solutions for your […]

Faces of Unity – Manuel Sainsily

Noutați

My parents always told me that art doesn’t pay – especially for minorities – and while I was talented and practiced different artistic hobbies, they hoped I would pursue medicine or law. But, I was obsessed with computers and design software, and was spending most of my time at home playing video games or creating worlds. So, when the time came to choose my path, I decided on a computer science program in Montreal. As a visible minority in a new country, I wanted to integrate myself and make a difference for my people. I started working in the tech industry as a designer, and always hoped to enter the gaming industry one day. Now, Unity allows me to do both design work and my own freelance projects in a very rewarding way, and I’ve found great communities and talented colleagues with similar interests. What’s a cool project you’re working on? A lot of my work involves immersive multisensory experiences and human-computer interaction, but the heart of my artistic process is my Caribbean culture, which connects me with music and nature.

How to Run Linux GUI Apps on Windows Subsystem for Linux

Delphi, Noutați

Windows 11 recently had some major updates early this year that introduced us to a vast of new exciting features. These recent updates offered a great number of benefits to the developers and brought tons of changes to windows application development. Interestingly, one of the most amazing features of Windows 11 is the ability to run Linux GUI Applications using the new version of Windows Subsystem for Linux or WSL2. Windows 11 recently expanded the Windows Subsystem for Linux (WSL2) with full GUI and X windows support. In this video, Jim McKeeth will help us better understand WSL2. He will show us how it works, proper setup, configuration options, and learn to target it in your application development. How do I setup and configure Windows Subsystem for Linux (WSL)? Windows Subsystem for Linux was introduced in Windows 10 which replaced Windows Services for Unix in 2004. It is developed in collaboration with Canonical and others. Generally, Window Subsystem for Linux (WSL) can be defined as a lightweight virtualization technology that makes it possible to execute Linux binaries on a Windows system. The webinar aims to introduce us to WSL and will teach us everything we need to know about its new version from installation to configuration and proper application. It will demonstrate how to test and run Linux applications on your Windows desktop without the need for a second computer or the overhead of a virtual machine. In the new version, you can run an actual Linux kernel which improves overall performance. The webinar will provide a step-by-step installation guide and a brief walkthrough of some of the available Linux distributions. From here, McKeeth will demonstrate how to properly set up and configure WSL in order to smoothly run your Linux GUI application in Windows. How can I write Delphi apps to run on Windows Subsystem for Linux (WSL)? The talk will also briefly guide us on how to properly set up Linux Distribution CentOS using a Docker container as well as the use of FMXLinux component in Delphi that provides capabilities for building GUI applications for Linux. To learn more about WSL2 and how to effectively run Linux GUI applications on Windows operating system, feel free to watch the webinar below.

Extend TMS WEB Core with JS Libraries with Andrew: Interact.js + BigText.js

TMS Software

In the last two outings, we covered some big JS libraries. Bootstrap and FontAwesome are wildly popular and with good reason. And getting started using them in your TMS WEB Core project couldn’t be simpler. This time out, we’re going to explore a pair of much smaller JS libraries. And we’ll have to get a little more hands-on using JavaScript in our code to best take advantage of them. Fortunately, there are plenty of code examples to draw from. First, we’ll look at Interact.js which is used to add the ability to drag and resize HTML elements on the page. And then we’ll pair this with BigText.js which is used to automatically scale text within an element to match its size. Motivation Using standard HTML and CSS, it is possible to create elements on a page that can be resized simply by using the CSS resize property. It takes values of none, horizontal, vertical, and both. And it works as expected, adding the familiar small diagonal lines to the bottom-right corner of the element, indicating that it can be resized. It even respects standard CSS properties like min-width, max-width, min-height, max-height to limit how far the element can be resized. But that’s about the extent of the feature. And as developers, we’d like to have a few more options available. Styling options. You get the diagonal lines in the corner. And that’s exactly all that you get. There’s not even an HTML element for it. It’s just ‘there’, wherever it decides ‘there’ is. Aspect Ratio. While it is possible to force elements to have an aspect ratio, it isn’t necessarily the easiest thing to do. There’s a new aspect-ratio CSS property that may help simplify this if you happen to know that your visitors use a browser that supports it, but that’s often not the case. UI. What if you want to start your resize from a different corner? Or an edge? Not happening with the standard CSS resize. Event Handling. If your app needs to know about the change (perhaps to save the new size for later), then you have to dig into more obscure JS functionality involving Observers to get this to work. Not so fun. Dragging. The CSS resize property allows only for resizing. Not really anything readily available to deal with dragging elements. Fortunately, Interact.js addresses all of these areas quite readily. And, once setup, you can add drag and resize functionality to any of your elements simply by adding CSS classes to them! Once you’ve got an element that is resizable, the next challenge is how to deal with its contents. Often, it doesn’t matter – longer bits of text or other elements can be set to wrap automatically, and this is likely what will happen by default anyway. And even the dimensions of the elements contained within or alongside the recently dragged and/or resized element can be set to automatically resize or flow in different directions, based on almost any kind of arrangement you can envision. Sometimes, though, it would be better if the text itself could be automatically scaled to fit the new dimensions. This is where the Event Handling aspect is important, as knowing when the element has been resized can then trigger this scaling function. While it is not a […]

Vue JS vs React: Pros And Cons

Sencha

Vue JS and React are both leading-edge competing technologies popular for front end development. Vue JS is a popular Javascript framework for creating simple and clean user interfaces along with single page applications. It supports a virtual DOM with two-way binding. It also has a progressive design, allowing you to migrate your existing projects one feature at a time. The React library is also very popular amongst developers. It supports a virtual DOM with two-way data bindings. Following a component based approach, React enables you to rapidly build complex web apps. Are you a developer at crossroads, trying to decide whether to use Vue or React for your next project? To make this decision easy for you, we have compiled a guide with pros and cons of both Vue and React. Continue reading to find out various aspects of application development when using Vue JS vs React, both supporting the integration of Sencha ExtWebComponents as described in the end. What is the Core Difference Between Vue and React? When it comes to the core difference, Vue is a complete standalone Javascript framework with its first release made in 2014. On the other hand, React is a Javascript library, first released in 2013 and has to be used in conjunction with other libraries. They are both open source. How are Components Built in Vue JS vs React? One of the most significant distinctions between Vue JS and React is the syntax, and the way the view layer is developed and components are built. In Vue JS, developers use HTML templates to build the components. The view layer uses HTML templates by default but Vue developers also have the freedom to use JSX. On the other hand, in React there is only one option and that is JSX. JSX is used to express both HTML and CSS using Javascript. JSX stands for Javascript XML and it is a Javascript syntax extension. JSX requires a tool/compiler such as the Babel transpiler, for conversion of code that can be to be further processed by a web browser. Which is Better, HTML Templates or JSX? If you use HTML templates, there will be a clear separation of concerns into HTML, CSS and JS. The view will be separate from the logic. JSX on the other hand, contains both HTML and CSS in one, allowing developers to build self contained and standalone UI components that hold everything from styles and rendering instructions to logic. At the end of the day, it’s all a matter of personal choice. For novice developers HTML templates are easier to learn and work with. They have a simpler design and cleaner code. However, expert developers find JSX a very powerful and flexible tool for building components. How Does the Performance of Vue JS and React Compare? Benchmarking experiments have shown that Vue and React have almost the same speed of execution for most tasks, with Vue being slightly better on most metrics. Vue has more built-in smart optimizations, while React does not have any. This gives Vue an edge over React. However, we have to keep in mind that the final speed and performance of an app heavily depends upon the coding style, application size and optimization.

Apocalypse Studios defines a new approach to narrative in Deadhaus Sonata

Noutați

“It’s easy to use and way faster than Perforce, by significant margins,” adds Dyack. “Pulling a build down takes two to three minutes, at most – before, it was taking much longer.” Migrating their game data from Perforce to Plastic took Apocalypse less than a day, and they were supported throughout the process by the Plastic team. Once they were up and running, Rogozinski, who had implemented Perforce previously, was shocked to see how much more efficient work became with Plastic – and not just because of how smoothly it handles large binaries: “I was very resistant to task branching at first. I didn’t want people working off-branch for a week or two, because you never know what’s going to happen when you merge it all back.” “I was totally wrong!” admits Rogozinski. “It’s working super well and the integrations are super easy, super fast. Plastic’s merge tools rival Perforce’s, easily.” Plastic SCM encourages a flexible “task-based branching” workflow that allows teams to work separately in sub-branches and conveniently merge changes without worrying about data loss or wasted work. With everything off of main, developers can pick and choose what they want to work with in the sub-branches, and stay off of the main branch for days at a time if necessary. “You never have to be afraid of breaking something,” reveals Pacheco. “You can bring the main branch into yours before you push it live, so you never have to worry about pushing content that breaks the build at five o’clock on a Friday.” “It’s a totally different methodology, and we really like it,” affirms Rogozinski.

3 Trends You May Have Missed About Windows App Development

Delphi

In a recent survey of 65 000 developers, StackOverflow finds that Windows is still the most used application development platform. This, in part, is because Windows app development meets the four requirements users must consider before choosing a platform — reach, simplicity, speed, and future proof. This is quite reiterated in Microsoft’s Windows 11 launch publicity which focuses a lot on developers. If anything, this new version of Windows shows the direction of the development platform for the next several years. With innovative features like the new Microsoft Store, new distribution methods, WinUI3 controls, the Windows app SDK, etc., Microsoft is affirming its position as a dominant operating system. With that being said, every software developer knows the importance of staying abreast of the latest industry trends. From rapid application development to low code solutions, application development trends change as fast as technology. To stay current, not only do you need to consider new platform features, but you must also pay attention to trends that can increase developer productivity. This article discusses 7 trends in Windows program development you may have overlooked. Is visual development making a come-back? Visual application development can be said to have originated as far back as the 1960s and 70s when developers sought improvements on typing numerous lines of code into a terminal window. Early on, the term Visual programming was often associated with Visual Basic, an IDE launched by Microsoft in 1991. This tool allowed users to develop applications by dragging and dropping code blocks and flowcharts. Borland then took the development world by storm with their launch of Delphi in 1995. With a similar “draw the user interface with a WYSIWYG interface but with a vastly superior experience due to Delphi’s ability to compile code natively – with a blindingly-fast compiler – with no dependencies which had plagued Visual Basic it quickly became the development IDE of choice for all sorts of developer scenarios ranging from small indie developers to large, sprawling blue-chip corporates where the reliability of Delphi apps which ‘just worked’ and kept on working made an awful lot of sense. In our fast-paced economy, developers are under increasing pressure to meet business needs. Demand to deploy new solutions faster, demand to deliver innovative and exciting features and a number of other competing requirements. Sometimes these expectations are unrealistic, but such has become the norm for developers today. Add to that the might of marketing muscles from organizations who were able to wield large advertising budgets to push and pull developer opinions things headed into all sorts of directions, not all of which were the best for the developer. While there may be development methods that claim to speed up Windows program development, none quite does it, like visual development. Hence, we’re seeing developers move towards tools that enable them to incorporate visual development. One such tool is the Delphi IDE. RAD Studio IDE, Embarcadero’s modern evolution of Borland’s phenomenally successful Delphi continues to pave the way for innovative Integrated Development Environments (IDEs), with what is surely the most advanced visual development toolset, an extensive array of unique features, shortcuts, and capabilities to improve development productivity significantly. Is rapid application development coming back in fashion? In 1991, James Martin, in his book, Applications Development Without Programmers, coined the term Rapid application […]

How To Use Cross-Platform Programming Languages: Expectations vs Reality

Delphi

Cross-Platform languages are not something new. For more than two decades, cross-platform development has been with us, but each programming language and technology evolved differently, adopted different architecture, and offered even more choices to consider. Today we are going to talk about different cross-platform programming languages, why they are good and what are their disadvantages and, through this learn how to choose and use the right cross-platform programming language and frameworks. What computer languages are available for cross-platform programming? Most programming languages provide at least some form of cross-platform development. By this we mean that with one codebase – the program’s source code – you can target most major operating system and device platforms. They have their specific UI framework and architecture that can or cannot directly utilize hardware features and platform-specific functionalities. Here are the top cross-platform programming languages C++ Java Delphi C# JavaScript Dart It is not easy to compare these languages, but they all have great features and problems. For instance, Java has a huge third party library pool with a high number of users but requires its Java Runtime Machine. JavaScript is everywhere but not secure & efficient as compiled languages. Microsoft’s C# has evolved so much, but its cross-platform frameworks are not the happiest. Dart with Flutter is getting attention because of its widget powered UI solutions for developing client-optimized apps. Still, it lacks third-party libraries and has problems with iOS development and is not an excellent choice for building server-side apps. C++ is a great choice, but it requires higher knowledge and practice about the ecosystem to develop apps fast. Delphi provides the fastest time to market option with high productivity when creating cross-platform native applications but has low open-source projects. How to choose a cross-platform programming language? If you can efficiently utilise hardware components and system-specific features, that is a good sign, like accessing the camera, gyroscope, or OS-specific features. Cross-Platform is one of the ongoing arguments in the software development industry. It is also noteworthy that Native and Cross-platform development is continuously evolving. While Native app development goes with a much more complex process, it stays true to the target platform, namely Windows, macOS, Linux, iOS or Android. To point out that these languages utilise a framework for building cross-platform responsive user interfaces and provide interfaces where you can use system provided APIs through them. Applications built with these frameworks should behave like native apps; if it does not, it breaks the user experience, leading to the decline of users from your product. For instance, applications built with web-powered components lack several ways that kill the native features, and it gets even hard to work with device hardware. What is currently happening in cross-platform development? Mobile market share is enormous, and most cross-platform languages target iOS and Android with their frameworks. Moreover, web apps can also do the job of a mobile app using technology like progressive web apps (PWA), which are web apps that act like a native apps albeit with some disadvantages such poor battery life and an inability to access many of the device’s hardware features. One of the latest frameworks for building cross-platform applications is the MAUI framework by Microsoft. It is a .NET Multi-platform App UI framework for building applications with C# and XAML. It is the […]
