  • Mike Blumenkrantz: Starting Over

    Up until now, I’ve been relying solely on my Intel laptop’s onboard GPU for testing, and that’s been great; Intel’s drivers are robust as hell and have very few issues. On top of that, the rare occasions when I’ve found issues have led to a swift resolution. Certainly I can’t complain at all about my experience with Intel’s hardware or software. But now things are different and strange because I received in the mail a couple weeks ago a shiny AMD Radeon RX 5700XT. Mostly in that it’s a new codebase with new debugging tools and such. Unlike when I started my zink journey earlier this year, however, I’m much better equipped to dive in and Get Things Done.

  • Zink OpenGL-On-Vulkan Development Now Being Done On RADV With Navi GPU

    Mike Blumenkrantz who has spent most of the year working on the "Zink" Gallium3D code for allowing universal OpenGL over Vulkan translation and took this Mesa code to OpenGL 4.6 compatibility and in some cases 90%+ the performance of a native OpenGL driver is now working on Zink development from a Radeon Navi graphics card with the RADV driver, which may in turn help uncover bugs and areas of optimizations for the open-source Radeon driver stack.  Blumenkrantz, who is now being funded by Valve as another Linux graphics driver developer and at least for now will continue devoting significant amounts of time to Zink, has switched his development system from using Intel graphics with the ANV Vulkan driver to now in large part using a Radeon RX 5700 XT "Navi" graphics card with RADV. 

Why Aren’t Viruses a Problem on Chrome OS?

Chrome OS has a reputation for being virus-proof. Google likes to boast about how secure its operating system is compared to others. Are Chromebooks really immune to viruses, though? And, if so, how do they achieve this? Allow us to explain. First, let’s consider what a computer virus actually is. Viruses fall under the umbrella of “malware.” They’re destructive because they inject a code into a file (usually, one that’s executable), and when that file is run, the malicious code is released. Once the code is released on your system, it can do any number of malicious things, like destroy data, overwrite files, or even replicate itself and spread to other systems. Read more

Reorganization and migration of Mercurial repositories

Since Richard Stallman adopted GNU Health in 2011, the development environment has been hosted at GNU Savannah, which generously provided a mercurial (hg) repository, that has been in use since then. Many years have passed, and GNU Health is today a Libre digital health ecosystem made of different components. In the last couple of years, GNU Health has been facing a tremendous growth, both in the community and in the development environment, yet, the hosting facilities at Savannah has remained pretty much the same. One of the issues I have faced is not being able to have multiple mercurial repositories to match all the new components. To give you an idea, this is a list of the GNU Health ecosystem components from 2011 and 2020. Read more

Do You Know How To Secure The OpenSSH Server?

In the last few articles, we have installed the OpenSSH server know we will see how to secure OpenSSH Server.

Already you know the SSH server is the best secure and simple and easy way to connect with the remote servers, router, and switches. Using OpenSSH gives you One more layer of security.

At the time of installing we just too basic setup but you need to tweak more to get a highly secure way to connect.

Few tweaks are required to harden security So, you just need to follow me and change or update the setting according to your need.

How to achieve high secure OpenSSH server?

At the time of accessing a remote server, it requires authentication we provide the password which we had created at the time of installation.

In this scenario, an evil guy will make some kind of guess or brute force to gain access to your servers, and actually, this type of password can be easily gained by an evil guy.

So, you are thinking about what to do now? Take a sigh of relief, Thanks to the community we have the option to set up SSH as a passwordless Authentication.
