  • The FSB’s personal hackers How Evil Corp, the world’s most powerful hacking collective, takes advantage of its deep family ties in the Russian intelligence community

    On December 5, the U.S. government formally indicted members of the Russian hacker group “Evil Corp.” Washington says these men are behind “the world’s most egregious cyberattacks,” causing hundreds of millions of dollars in damages to banks. The Justice Department believes Evil Corp’s leader is Maxim Yakubets, who remains at large and was still actively involved in hacking activities as recently as March 2019. Meduza investigative journalist Liliya Yapparova discovered that Evil Corp’s hackers belong to the families of high-ranking Russian state bureaucrats and security officials. She also learned more about the Russian intelligence community’s close ties to Maxim Yakubets, whose arrest is now worth $5 million to the United States.

Programming Leftovers

  • Fedora 32 Will Feature Bleeding-Edge Compilers Again With LLVM 10 + GCC 10

    Fedora Linux is on track to deliver another bleeding-edge compiler toolchain stack with Fedora 32 due out this spring.  Fedora's spring releases have tended to always introduce new GNU Compiler Collection (GCC) releases that are generally out a few weeks before the April~May Fedora releases. Thanks to Red Hat employing several GCC developers that collaborate with Fedora, they tend to stick to ensuring Fedora ships new GCC releases quite quickly while managing minimal bugs -- in part due to tracking GCC development snapshots well before launch to begin the package rebuilds. 

  • What makes Python a great language?

    I know I’m far from the only person who has opined about this topic, but figured I’d take my turn. A while ago I hinted on Twitter that I have Thoughts(tm) about the future of Python, and while this is not going to be that post, this is going to be important background for when I do share those thoughts. If you came expecting a well researched article full of citations to peer-reviewed literature, you came to the wrong place. Similarly if you were hoping for unbiased and objective analysis. I’m not even going to link to external sources for definitions. This is literally just me on a soap box, and you can take it or leave it. I’m also deliberately not talking about CPython the runtime, pip the package manager, venv the %PATH% manipulator, or PyPI the ecosystem. This post is about the Python language. My hope is that you will get some ideas for thinking about why some programming languages feel better than others, even if you don’t agree that Python feels better than most.

  • Python String Replace

    In this article, we will talk about how to replace a substring inside a string in Python, using the replace() method. .replace() Method In Python, strings are represented as immutable str objects.
