  • AMD OverDrive Overclocking To Finally Work For Radeon Navi GPUs With Linux 5.5 Kernel

    While most Linux gamers don't appear to be into GPU overclocking, one of the limitations of the Radeon RX 5000 "Navi" series support with the AMD open-source driver to date has been no overclocking support. With the upcoming Linux 5.5 kernel that is set to change.

    With the Linux 5.5 kernel there is slated to be the "OverDrive" overclocking support in place for Navi graphics processors with the AMDGPU kernel driver.

  • EXT4 On Linux 5.5 To Support Encryption On Smaller Block Sizes

    For the past four years going back to Linux 5.5 has been EXT4 native file-system encryption making use of the kernel's FSCRYPT framework that is shared between several file-systems. That support has continued to improve with time and with Linux 5.5 another limitation will be dropped.

    One of the lingering limitations of the EXT4 encryption code is that it hasn't worked where the file-system block size is different from the system's page size. But beginning with Linux 5.5, a different block size compared to the kernel's page size will be supported while still allowing encryption to be enabled. Namely this will help those preferring non-default block sizes for better efficiency on different storage devices or other reasons.

  • 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. The str class comes with many methods that allow you to manipulate strings. The .replace() method takes the following syntax: str.replace(old, new[, maxreplace]) str - The string you are working with. old – The substring you want to replace.

Google Now Bans Some Linux Web Browsers From Their Services

Google is now banning the popular Linux browsers named Konqueror, Falkon, and Qutebrowser from logging into Google services because they may not be secure. It is not known when Google started blocking these browsers, but a user discovered this ban yesterday and posted about it on Reddit. In tests conducted by BleepingComputer, we can confirm that we were unable to log in with Konqueror or Falkon on multiple machines. When attempting to do so, we were told to try a different browser as Konqueror or Falkon may not be secure. Read more
