  • Create the third level for this pygame project

    In this article we are going to create the third level for our pygame project after we have created the previous two levels, the reason I create the third game level in this chapter is because this level is different from the second level which is only using the same enemy class to generate different type of enemy ship. In this chapter we are going to create a new enemy class which will act...

  • Introducing Zato public API services

    Most users start to interact with Zato via its web-based admin console. This works very well and is a great way to get started with the platform.

    In terms of automation, the next natural step is to employ enmasse which lets one move data across environments using YAML import/export files.

    The third way is to use the API services - anything that can be done in web-admin or enmasse is also available via dedicated API services. Indeed, both web-admin and enmasse are clients of the same services that users can put to work in their own integration needs.

    The public API is built around a REST endpoint that accepts and produces JSON. Moreover, a purpose-built Python client can access all the services whereas an OpenAPI-based specification lets one generate clients in any language or framework that supports this popular format.

  • 6 steps to optimize software delivery with value stream mapping

    Do your efforts to improve software development fall short due to confusion and too much debate? Does your organization have a clear picture of what is achievable, and are you sure you’re moving in the right direction? Can you determine how much business value you've delivered so far? Are the bottlenecks in your process known? Do you know how to optimize your current process?

    If you are looking for a tool that will help you answer these questions, consider integrating value stream mapping and lean concepts into the way you deliver software.

The Year 2018 in Open Hardware and MIT's 3D Printer

  • The Year 2018 in Open Hardware
    2018 saw several open hardware projects reach fruition. Where the open hardware movement goes from here, remains to be seen. 2018 was not “The Year of Open Hardware,” any more than it was the fabled “Year of the Linux Desktop.” All the same, 2018 was a year in which open hardware projects started to move from fundraising and project development to product releases. Many of these open products were traditional hardware, but 2018 also saw the release of innovative tech in the form of new and useful gadgets. In the background, open hardware hangs on to traditional niches. These niches occur at the intersection of altruism, hobbyists, academia, and the market, to say nothing of crowdfunding and the relative affordability of 3D printing. A prime example of this intersection is the development of prosthetics. Much of the modern work in open hardware began almost a decade ago with the Yale OpenHand project. At the same time, sites like Hackaday.io offer kits and specifications for hobbyists, while the e-NABLE site has become a place for exchanging ideas for everyone from tinkerers to working professionals in the field. As a result, open hardware technology in the field of prosthetics has grown to rival traditional manufacturers in a handful of years. This niche is a natural one for open hardware not only because of the freely available resources, but for simple economics. Traditionally manufactured prosthetic hands begin at about $30,000, far beyond the budgets of many potential customers. By contrast, an open hardware-based company like the UK based Open Bionics can design a cosmetically-pleasing hand for $200, which is still a large sum in impoverished areas, but far more obtainable. A non-profit called Social Hardware estimates that a need for prosthetic hands in India alone numbers 26,000 and hopes to help meet the demand by offering a development kit on which enthusiasts can learn and later donate their results to those who need them.
  • This MIT Developed 3D Printer Is 10 Times Faster Than Modern 3D Printers
    3D printers have become more and more useful in the mass production of complex products that are cheaper and stronger. However, the only issue with 3D printing is its slow speed. These desktop 3D printers can print only one product at a time and only one thin layer at a making.
  • Accelerating 3-D printing
    Imagine a world in which objects could be fabricated in minutes and customized to the task at hand. An inventor with an idea for a new product could develop a prototype for testing while on a coffee break. A company could mass-produce parts and products, even complex ones, without being tied down to part-specific tooling and machines that can’t be moved. A surgeon could get a bespoke replacement knee for a patient without leaving the operating theater. And a repair person could identify a faulty part and fabricate a new one on site — no need to go to a warehouse to get something out of inventory.

Programming: Linux Direct Rendering Manger Subsystem, Python, QtCreator CMake, Rust and More

  • The Linux Direct Rendering Manger Subsystem Poised To Have A Second Maintainer
    For hopefully helping out with code reviews and getting code staged in a timely manner before being upstreamed to the mainline Linux kernel, Daniel Vetter of the Intel Open-Source Technology Center is set to become a co-maintainer.  Daniel Vetter who has been with Intel OTC for a number of years working on their Linux graphics driver has proposed becoming a DRM co-maintainer, "MAINTAINERS: Daniel for drm co-maintainer...lkml and Linus gained a CoC, and it's serious this time. Which means my [number one] reason for declining to officially step up as drm maintainer is gone, and I didn't find any new good excuse."

    It’s about QtCreator CMake for Android! I know it’s a strange coincidence between this article and The Qt Company’s decision to ditch QBS and use CMake for Qt 6, but I swear I started to work on this project *before* they announced it ! This plugin enables painless experience when you want to create Android apps using Qt, CMake and QtCreator. It’s almost as easy as Android Qmake QtCreator plugin! The user will build, run & debug Qt on Android Apps as easy as it does with Qmake.

  • Processing CloudEvents with Eclipse Vert.x
    Our connected world is full of events that are triggered or received by different software services. One of the big issues is that event publishers tend to describe events differently and in ways that are mostly incompatible with each other. To address this, the Serverless Working Group from the Cloud Native Computing Foundation (CNCF) recently announced version 0.2 of the CloudEvents specification. The specification aims to describe event data in a common, standardized way. To some degree, a CloudEvent is an abstract envelope with some specified attributes that describe a concrete event and its data.
