  • New Tax Collection Tech Replaces 50-Year-Old System

    Fried said recent updates to the old system had fallen mainly to a single employee who had worked for the office for most of the five decades the system had been in place - and finding another programmer with similar skills would have been challenging. The old system used the COBOL programming language and a traditional mainframe computer, whereas the new system is cloud-based and can be managed entirely remotely.

  • Godot Release candidate: 3.2.3 RC 3

    Godot 3.2.2 was released on June 26 with over 3 months' worth of development, including many bugfixes and a handful of features. Some regressions were noticed after the release though, so we decided that Godot 3.2.3 would focus mainly on fixing those new bugs to ensure that all Godot users can have the most stable experience possible.

    Here's a third Release Candidate for the upcoming Godot 3.2.3 release. Please help us test it to ensure that no new regressions have slipped through code review and testing.

    Note: The previous 3.2.3 RC 2 was actually not built from the intended commit, and reflected the same changeset as RC 1. Tests made on RC 2 are still valid and useful, but did not help validate the very latest commits, hence this third release candidate. The changes new in this build are thus the ones made between RC 1 and RC 3.

  • What Is Fuzz Testing? A Guide.

    Not all software testing techniques have origin stories, but fuzz testing does: On a stormy evening in 1988, Barton Miller, a computer science professor at the University of Wisconsin-Madison, was using a dial-up connection to work remotely on a Unix computer from his apartment. He was attempting to feed input information into a computer program, only to see the program repeatedly crash.

    He knew that the electrical noise from the thunderstorm was distorting his inputs into the program as they traveled through the phone line. The distorted inputs were different from what the software needed from the user, resulting in errors. But as he describes in his book, Fuzzing for Software Security Testing and Quality Assurance, Miller was surprised that even programs he considered robust were crashing as a result of the unexpected input, instead of gracefully handling the error and asking for input again.

    [...]

    Miller’s concern about what he saw during his thunderstorm experience extended beyond the annoyance of having applications crash unexpectedly. Applications that are not able to handle unexpected input also pose security concerns. Errors that aren’t handled by the program are vulnerabilities that attackers can exploit to hack into systems.

    In fact, attackers often use fuzz testing tools to locate vulnerabilities in applications, according to Jared DeMott, the CEO of VDA Labs security testing company and the instructor of several Pluralsight courses on testing.

    “If you follow what we call a secure development lifecycle… fuzzing is one piece of the lifecycle that relates to the testing portion of it,” DeMott said.

Intel Announces 12th Gen Core "Alder Lake" CPUs, Linux Tests Forthcoming

Intel is using their inaugural Intel Innovation virtual event today to formally announce the highly-anticipated 12th Gen Core "Alder Lake" processors. These first desktop processors built on their "Intel 7" process and employ a hybrid architecture will be available in retail channels next week. Today we can talk more about Alder Lake specifications and features while our Linux performance benchmarks and support analysis will come once the Alder Lake review embargo expires next week. While there have been many Alder Lake leaks in recent weeks/months and a number of features disclosed back during Architecture Day, today marks the official unveil for the next-gen Intel Core processors. This is a very exciting transition as they have now shifted to their Intel 7 manufacturing process, the hybrid architecture provides a combination of high performance and low power cores depending upon needs, and Intel is at the forefront now in delivering DDR5 memory and PCIe 5.0 to the masses. When it comes to performance, Intel claims Alder Lake can deliver up to two times the performance of prior generation processors for content creation workloads. Meanwhile when it comes to the generational performance uplift for the P (Performance) cores it's said to be around 19%. Read more

Murena smartphones and cloud will protect our privacy

More than ever the market is demanding a new approach for digital products: more and more people around the world want something different, more ethical, more sustainable, with real guarantees about personal data protection. Four years ago, I wanted to break free from Google and Apple, and therefore we created the “eelo” project, with the simple idea that a different mobile operating system and associated cloud services like email or cloud storage could be possible in this world. Followed by an amazing community of supporters, contributors and now users, the project progressed quickly, and became a reality by the end of 2018. The same year, we had to suddenly abandon our initial project name for a temporary name: /e/. Sometimes, temporary things last longer than expected. And despite being hard to pronounce, difficult to search, and largely criticized by many people, /e/ as a brand name had the benefit to be very singular and helped us appear different. In the end it conveyed the idea that we’re doing something special. […] Nevertheless, as we are reaching more and more people and progressively catching interested from a mainstream audience, we have to introduce a new, strong brand, easier to use, easier to refer to and easier to share with people. The goal of this brand is to have a strong name to call our products, intended to be used by a large number of users in many different countries and cultures. It took some time, since we had many different candidates, both from internal suggestions and from our community. We wanted something that would both convey our project’s values, and that could be within the same lineage of our initial project name. We also had to secure this new brand making sure it was not already in use in the same field of activity, and by entering a long trademark registration processes. Read more
