5 Best Ways To Secure Your Linux System Distribution

Filed under
Linux

There are many ways to secure your Linux system distribution. Today, cyber attacks and computer hacking can be prevented by bolstering security systems. By securing a Linux system, a computer is shielded from identity theft, data extraction, and other forms of malware. Different ways of securing a Linux system can teach users how to avoid spam, scams, and phishing campaigns. As a Linux developer, you should follow basic principles to increase privacy, security and stability. In this article, we’ll discuss the best ways you can secure your Linux system.

Enable full disk encryption (FDE) to secure your Linux system. You should encrypt your entire hard disk regardless of which operating system you are using. This will ensure that your data remains secure if the device is stolen. First, take advantage of full disk encryption at install time if possible. By encrypting your hard disk, a criminal will be unable to extract your information without an FDE password. Encrypt your full disk so you don’t have to worry about temporary files, swap files, or other directories containing sensitive information. Furthermore, you will notice that encrypting your full disk allows your computer to function at a similar level of performance. Certainly, consider FDE as a cybersecurity tip to help Linux users protect their computers.

Raspberry Pi 4 2GB jumps to $45 as 1GB model returns from the dead at $35

Filed under

Hardware

Citing chip shortages, Raspberry Pi announced its first price increase, bumping the RPi 4 with 2GB RAM up to $45. Meanwhile, the discontinued RPi 4 1GB has come back to life at $35.

In the spirit of Halloween, Raspberry Pi Trading has reanimated the 1GB RAM version of the Raspberry Pi 4 Model B, which it killed off when it dropped the price of the 2GB model from $45 to $35 in Feb. 2020. The company also increased the 2GB price to $45. With the 1GB version returning at its old $35 price, we have essentially turned back the clock to early 2020. (In which case, maybe we could get a second chance on stopping the pandemic.)

In the Raspberry Pi blog post announcing the changes, CEO Eben Upton cited industry-wide supply chain issues for its first price increase in Pi history. The chip shortages, combined with heightened demand, have caused severe shortages of the RPi Zero and the RPi4 2GB.

The love/hate relationship the cloud has with Linux

Filed under
Linux

The cloud is run by Linux and open-source. There is no debating that claim at this point. It's fact. And not only does Linux power all of those cloud services we deploy and use, but the hold it has over that particular tech sector is also only going to get stronger as we march into the future. I predict that, over the next five years, the cloud and Linux will become synonymous to the point everyone (from CEOs to end-users) will finally get just how important and powerful the platform is.

So it's safe to say, there would be no cloud without Linux.

There would also be no cloud-native development, Kubernetes, Docker, virtual machines or containers in general.

With that in mind, it should stand to reason that the relationship between Linux and the cloud would be all love.

  • Intel teases 'software-defined silicon' with Linux kernel contribution – and won't say why

    Intel has teased a new tech it calls "Software Defined Silicon" (SDSi) but is saying almost nothing about it – and has told The Register it could amount to nothing.

    SDSi popped up around three weeks ago in a post to the Linux Kernel mailing list, in which an Intel Linux software engineer named David Box described it as "a post-manufacturing mechanism for activating additional silicon features".

  • RadeonSI Lands Another "Very Large" Optimization To Further Boost SPECViewPerf - Phoronix

    In recent months we have seen a lot of RadeonSI optimizations focused on SPECViewPerf with AMD seemingly trying to get this open-source OpenGL driver into very capable shape moving forward for workstation GL workloads. Hitting Mesa 22.0-devel today is yet another round of patches for tuning SPECViewPerf.

  • Vendors Including NVIDIA Talk Up New OpenCL Extensions For Vulkan Interop, NN Inference - Phoronix

    Last Friday night we spotted OpenCL 3.0.9 with several new extensions included. Today The Khronos Group is formally announcing these latest OpenCL additions focused on Vulkan interoperability as well as neural network inferencing.

    These new extensions for OpenCL 3.0 include an integer dot product extension for neural network inferencing (cl_khr_integer_dot_product) with a focus on 8-bit integer support.

  • RadeonSI Enables NGG Shader Culling For Navi 1x Consumer GPUs - Phoronix

    As another possible performance win for RadeonSI Gallium3D as AMD's open-source Radeon OpenGL driver on Linux systems is enabling of NGG culling for Navi 1x consumer graphics processors rather than limiting it only to newer Navi 2x (RDNA2) GPUs.

    Merged on Monday was a patch to enable shader culling for Navi 1x consumer SKUs with no longer limiting it to Navi 2x / GFX10.3 or when using various debug options. This culling was also enabled for Navi 1x GPUs but only for the "Pro" graphics SKUs.

Best Linux distro for power users in 2021

Filed under
Linux

The Linux power user is a celebrated breed, and one that does not simply burst fully-formed from the earth. All newbies must toil long and hard with their Linux installations before they can describe themselves as one.

At the very least, the power user will have a great degree of skill concerning all things Linux, whether it's the kernel, Bash or package management systems – and they won’t be afraid to get their hands dirty in the name of configuring the system.

It seems, in many ways, that power users are a dying breed. Almost all modern Linux distributions require little effort to get up and running, or to install new software or configure basic functionality. By definition, no power user will want to run any of these distros. This is why, despite their popularity, the likes of Ubuntu and Mint are not featured here.

On the other hand, control and flexibility are the hallmark of any distro meant for power users. The ones in this feature are user-driven, not guided. This gives them much greater adaptability, as well as allowing them to perform a diverse range of tasks.

Radeon RX 6600 Linux Performance Rising Even Higher With Newest Open-Source Driver

Just one week ago was the public launch of the Radeon RX 6600 as the newest offering in the RDNA2 GPU line-up. While in our Radeon RX 6600 Linux review the performance was good on AMD's well regarded open-source driver stack and standing ground against the likes of the GeForce RTX 3060 with NVIDIA's proprietary Linux driver, it turns out the RX 6600 Linux performance can be even better already. Here are benchmarks of the Radeon RX 6600 on Linux across six different driver configurations. In particular, it appears that the driver state around 1 October that was used for the launch-day RX 6600 Linux review is actually less than ideal -- there appears to have been a regression around that point and with newer (as well as 21.2 stable) driver code there can be measurable gains to Linux gaming performance.

You Can Now Install the UnityX Desktop in Arch Linux, Here's How

UnityX is the successor of the Unity7 desktop environment created by Canonical for its popular Ubuntu Linux distribution back in 2011 with the Ubuntu 11.04 release. But Canonical pulled the plug on Unity7 after seven years of development, yet the community wasn’t ready for this major change. In May 2020, developer Rudra Saraswat created an unofficial Ubuntu flavor called Ubuntu Unity, which features the good old Unity7 desktop environment. Now, the Ubuntu Unity creator wants to take Unity7 to the next level and created UnityX, a modern, yet simple desktop environment. Read more
