  • 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...

    When you first learn to code, it’s common to learn arrays as the “main data structure.”

  • 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.

Security: GNU/Linux in Space (After Windows Viruses), Fingerprint Pseudo-Security, Mainframe Security and Slackware Updates

  • Space: New cybercrime battlefield? [Ed: Space has already dumped Microsoft Windows and moved to GNU/Linux (Debian) for security reasons. The famous incident has just been mentioned here.]
    In the same vein, is it believable for a virus to infect a space station orbiting at a distance of over 330 km above the earth? It shocked astronauts on board to find their Windows XP-based laptops on the International Space Station (ISS) infected with a virus called W32.Gammima in 2008. Gammima.AG worm is a malware that gathers and transmits sensitive gaming data to an attacker. Investigations later revealed that unsuspecting Russian cosmonauts had inadvertently carried infected USB storage devices aboard the station spreading computer viruses to the connected computers. The damage by the malware to the computer systems of the ISS is unknown to date.
  • OnePlus 7 Pro Fingerprint Scanner Hacked By Classic Hacking Technique
    OnePlus has recently launched its much-awaited OnePlus 7 Pro which is considered as one of the best smartphones of 2019 by many. Packing the latest Snapdragon processor, triple camera setup, UFS 3.0 and a 30W Warp Charging, the smartphone is a complete package but how safe is it? Speaking of safety, a YouTuber has managed to hack the in-display fingerprint scanner of OnePlus 7 Pro within a few minutes. Going by the name Max Tech, this YouTuber deployed the classic print molding hacking technique to get past the fingerprint reader. If you have bought the smartphone or you’re a potential buyer then I must tell you that OnePlus 7 Pro is not the first device to be hacked by this technique.
  • Just how secure are mainframes?
    The days of mainframe security by obscurity are long gone. Everyone – especially hackers – knows that there are lots of valuable data sitting on mainframes. So, how aware are mainframe-using organizations about what it takes to secure all the components of a mainframe environment? Key Resources Inc has announced the findings from a new study conducted by Forrester Consulting carried out in February 2019. The survey questioned 225 IT management and security decision makers in North America.
  • [Slackware] April ?19 release of OpenJDK 8
    Early May I was confined to my bed, immobilized on my side and under medication, after I had incurred a second back hernia in four months’ time. And so I missed the announcement on the OpenJDK mailing list about the new icedtea-3.12.0. Why again is that important? Well, the IcedTea framework is a software harness to compile OpenJDK with ease. Andrew Hughes (aka GNU/Andrew) who is the release manager still did not update his blog with this announcment, but nevertheless:  the new Java8 that we will get is OpenJDK 8u212_b04. This release syncs the OpenJDK support in IcedTea to the official April 2019 security fixes for Java. I built Slackware packages for Java 8 Update 212 so that you do not have to succumb to the official Oracle binaries which are compiled on God-knows what OS.

KDE: Krita Interview, KDE Developer Documentation and KDE Craft Packager

  • Krita Interview with Anna Hannon
    I opted for trying Linux Mint, and tested Krita as my Photoshop replacement. Love at first sight! I currently run Manjaro KDE and it continues to be my only painting software (even on my Microsoft surface).
  • KDE Developer Documentation Update: Far from the Endgame
    It has been nearly three months since I embarked on an adventure in the land known as dev docs. And while the set period for that work is coming to a close, the truth is that the journey has really only just begun. Just like the pioneers of old, the first important step is to get to survey the land and map it for future adventurers. The KDE community’s developer documentation isn’t exactly new territory but, through the years, it has grown from a garden to a huge forest with only a brave few doing the work to keep things from getting out of hand. They could use a helping hand.
  • KDE Craft Packager on macOS
    In Craft, to create a package, we can use craft --package after the compiling and the installing of a library or an application with given blueprint name. On macOS, MacDMGPackager is the packager used by Craft. The MacDylibBundleris used in MacDMGPackager to handle the dependencies. In this article, I’ll give a brief introduction of the two classes and the improvement which I’ve done for my GSoC project.
