Effective Tips To Improve Linux Environment

Filed under
Linux

Many people have used the Windows environment for several years and before they migrate to Linux, they feel like they are in a different world. Linux was released in 1991 and has been a free, open-source OS that has gained immense popularity in the world of technology. It offers several benefits to the users but to enjoy better performance, you need to pay attention to Linux installation. Domain brokerage service experts have seen a rise in the number of buyers running their systems on a Linux environment. It is important to ensure that the environment runs smoothly and effectively so as to avoid any challenges to the crucial applications. Let us take a look at some tips to improve the Linux environment.

There are several background elements and services running on every server in Linux. But all these components are not always necessary. Such extras will take up a lot of CPU and RAM space. It is best to incapacitate them with the startup script which starts the unnecessary services in the booting time. Once you disable the extra services, it is possible for you to make more memory space available, boost the performance of the OS, and cut the start-up time.

Extreme Overclocker Takes Raspberry Pi to 3 GHz

Filed under

Hardware

Some people will do anything for a speed boost, prying the lids off expensive i9s and subjecting them to all manner of chilly chemical concoctions to drag every last megahertz out of the silicon. We’ve not seen anybody do such an extreme overclock with a Raspberry Pi before, but there's a first time for everything. Claude Schwarz has overclocked his Raspberry Pi Compute Module 4 to an extraordinary 3 GHz.

[...]

Schwarz's earlier efforts saw him overclock the Compute Module 4 to 2.89 GHz, still an extreme speed boost over the stock 1.5 GHz. As well as using liquid metal thermal paste, Schwarz used active cooling on the Compute Module 4 in the form of a heatsink and fan designed for the Raspberry Pi (which could be a 52Pi model cooler). Taking the steps to overclock even further Schwarz disabled power management features to unlock a higher overclock, resulting in much higher CPU speeds than we can achieve with a typical overclock. We should probably say at this point that anyone doing this is on their own, as these extreme actions will definitely void your warranty, and we take no responsibility for whatever happens if you try it.

A little more fumbling in the Pi’s firmware - what Schwarz refers to as “removing all safety nets” - and the CM4 is running at an impressive 2.4GHz at 26.2°C (79.16°F). Not bad for a board that started life at 1.5GHz and didn’t require cooling.

Arch Linux vs Ubuntu: which to choose?

Filed under
Linux
Ubuntu

Arch Linux and Ubuntu are two major Linux distributions that both get a lot of attention, have dedicated fanbases, and are used base-distributions for other systems that are forked off of them… But, how they do things are quite different, and some users might find one more to their liking than the other.

It’s no secret to anyone who has followed previous articles I’ve written on Ghacks, that I love Arch Linux and its derivatives… But, that’s not to say that Ubuntu and Ubuntu-based systems are something I don’t use. Actually, I have multiple Ubuntu systems running as I write this, and zero Arch based systems. I use Ubuntu as a server distribution right now, on three different servers. I love the APT system for package management, and I find Ubuntu stable and secure, with a huge support community for any issues I may face.

For UEFI installs it is now possible to select between systemd-boot, rEFInd or no bootloader, all presented in a nice, QML based GUI. Second change is the addition of an interactive keyboard preview in the keyboard setup page. And third is the porting of the License page to QML.
