Suggested January 2024 How To Install Openrazer On Linux
One of the things that’s most frustrating about building a new computer for Linux is peripherals, especially for gamers who are looking for lots of functionality out of their peripherals. If you have Razer peripherals, you may be in luck, because the OpenRazer project has a solution for you. Here we go over how to install OpenRazer on Linux.Getting Started
The first place you should go is the project’s chúng tôi page. You can see what devices are supported and learn more about the installation process. It’s fairly simple, but it does take a bit of time and planning.
Note: I have a Razer Basilisk Essential, which is in the process of being supported, but I’ll still demonstrate the process.Installing OpenRazer
First, add the user you log in as to the plugdev group. This ensures you will have control over pluggable devices, like mice and keyboards. To do that, simply run the following command:
After that, you can follow the specific instructions for your distro that are listed on the page.Arch Linux
For Arch users, openrazer is in the AUR, which is quite convenient. They suggest using pacaur to install in order to avoid dependency loops.All Other Officially Supported Distros
All other officially supported distros should get their packages from the OpenSUSE build service. There are commands available for you to use, and they vary based on your distro. For Fedora, I’ll be running these commands:
For Ubuntu, run these commands:
For OpenSuse, which seems to be the best supported, run these commands:
zypper refresh zypper
You can find the commands for your distro there.For Community-Supported Distros
There are various communities that have stepped up and worked out different ways to support OpenRazer on their distros. You can reference the installation instructions on their website. Some distros like Solus and Void Linux have made it very simple.
Once you have OpenRazer installed, restart your computer, and you should be able to then install one of the graphical front ends listed on their website, which are Polychromatic, RazerGenie, razerCommander, and Snake.Troubleshooting General
Make sure you add your user to the plugdev group. Some distros might not have it, but it’s a really important step that allows your user to control those devices.
Also, if you’re having trouble with a device, make sure it’s on the supported devices list. It sounds simple, but if your particular variation of a device is not supported, the device won’t work. OpenRazer will pick up that it’s a Razer device, but it won’t know how to talk to it. Take my Basilisk Essential, for example. The Basilisk is supported, and I bought the Basilisk Essential thinking it would be the same thing. Big mistake.Fedora
There is a bug specifically with Fedora that makes it install the wrong kernel headers. To counteract that, install the kernel-devel package before you do anything else by running this command:
Hopefully, with the help of OpenRazer, you can get the best out of your Razer peripherals on your Linux system. If your Linux system is running slow, find the cause here. Also, learn how to use the Hosts file to access websites in Linux.

If you are a content creator, especially a video editor, then you have heard about DaVinci Resolve. DaVinci Resolve is known for its color correction capabilities in large film studios and comes with a powerful video and audio editor and composer, like Adobe After Effects, making it a go-to creative software among Linux creators. Unlike other creative software, DaVinci Resolve supports the Linux platform, so you don’t need any windows API translation layer like wine to install DaVinci Resolve.Download Linux Binaries
Go to the DaVinci Resolve release page and download the latest version. At the time of writing, the latest version is version 18. DaVinci Resolve comes in two versions: free and paid. Select and download the Linux binaries and save them in your download folder.Install Required Drivers
DaVinci Resolve is heavily dependent on GPU processing. If you have a recent Intel or AMD APU, then your integrated GPU may run DaVinci Resolve on your device. In most cases, you need an Nvidia GPU to run this software. Install the latest Nvidia drivers and CUDA for your Nvidia GPU in your Linux machine.Install the Latest Nvidia Driver In Ubuntu
For Ubuntu-based distributions, it is very easy to install GPU drivers. Run these commands for rebooting to install the Nvidia GPU for you.
]Install the Latest Nvidia Driver in Debian
For Debian-based distributions, you have to do something more than run some commands. Open the “/etc/apt/sources.list” file:
Add this line in the chúng tôi file. If it’s already present, append the contrib and non-free component.
To install Cuda, you only need to run one command:
After installation, reboot your device so that the changes can take effect.
sudosystemctl reboot Install the Latest Nvidia Driver in Fedora
To install the Nvidia driver in Fedora Linux, you first need to enable the RPM fusion repository.
Detect the Nvidia GPU and install the required drivers.
After installation, reboot your machine and you are good to go.
sudoreboot Build a Deb Package
The DaVinci Resolve Linux build was released to run on CentOS, a RedHat-owned distribution. Therefore, If you are using Fedora or another RedHat distribution, you don’t need to follow the build step.
For Debian and Ubuntu-based distributions, you have to convert the DaVinci Resolve .run file into a .deb file.
To make this conversion possible, download and extract the MakeResolveDeb script.
Create a folder and copy the DaVinci Resolve Installer and MakeResolveDeb script into the folder.
Before the conversion, install some required dependencies to build and run DaVinci Resolve flawlessly.
installlibssl1.1 ocl-icd-opencl-dev fakeroot xorriso
Run the following command to convert your .run file to a .deb file, assuming that you put both the script and .run installer into the same folder..
It is quite an intensive process, so give your machine some time to extract and build the .deb package for you. When completed, you will be greeted with a .deb file ready to be installed.Installing Deb Package
Installing a .deb file is really easy in Debian and Ubuntu derivatives. Run this command to install the package:DaVinci Resolve Free vs. Paid
The DaVinci Resolve free version comes with all the basic features you need to edit your video, make motion graphics, color correct and edit your sounds.
All the studio features are required if you are working on a huge project, like filmmaking and documentaries. To make simple YouTube videos, the free version is enough for most users.
If you buy any Blackmagic gadgets, you get the studio version free of cost. If you are a professional video editor, consider buying the gadgets you may need.Video Transcode to Use in Davinci Resolve
In the free version of DaVinci Resolve, the H264 codec is not supported. Therefore, if you record video using this codec, you have to transcode the video to another format that DaVinci Resolve supports. To transcode our video, we are using FFmpeg.
FFmpeg is a very powerful video transcoding and processing library and has many customization options. You can read the documentation to customize FFmpeg. To install it on your device, run the following command:
To edit your video inside DaVinci Resolve, you have to convert it to .mov format.
1001-b:v 36M -pix_fmt yuv422p
-fmov chúng tôi the above command, it’s assumed your input file is “input.mp4” and the output file name is “output.mov.” You can change the names according to your preference.
To convert .mkv to .mp4, run the following command.
1001-b:v 36M -pix_fmt yuv422p
-fmov chúng tôi Up OBS Studio for Davinci Resolve
If you want to edit your screen recordings using DaVinci Resolve and don’t want to transcode your recorded file every time you want to edit, then you have to change some settings in your OBS application.
Switch to the recording tab and change the output type to the custom output option (FFmpeg). Select “MOV” as the container format and “mpeg4” as a video encoder. In the audio encoder option, select the “pcm_s16le” option. You can refer to the settings below and make changes in your OBS software accordingly.
Save the settings and restart the OBS software. You can test if the settings are working or not by recording a little clip and importing it into your DaVinci Resolve software.Transcode for Online Upload and Save Space
You can see that when we transcode the files to edit in DaVinci Resolve, the sizes are very big – sometimes hundreds of gigabytes. Therefore, editing and uploading the rendered file of a few hundred gigabytes takes a very long time. Even if you want to store the files on your hard disk, those sizes are very huge compared to their length.
To fix this issue, we are using FFmpeg to transcode and compress our file. Run the following command in your terminal:
-vfyadif -codec:v libx264
-flags+cgop -pix_fmt yuv420p -codec:a aac
-2-b:a 384k -r:a
“input.mov” is your .mov file from DaVinci Resolve, and “output.mp4” is your output .mp4 file. You can change these names to your preference.
You can change the compression and output quality by adjusting the -crf flag. By default, I set it to 1, the highest quality. You can set this flag up to 25 for maximum compression. It also reduces video quality when -crf is a very high number.Frequently Asked Questions Is DaVinci better than Premier?
It is about personal choice. If you are familiar with Premier, and your editing workflow revolves around Adobe software, then it is better to use Premier than Resolve. If you are a newbie and want to learn DaVinci Resolve, then you are good to go. If you are an M1 Mac owner, then DaVinci Resolve runs better in Apple M1 Macs.Is 8GB RAM enough for DaVinci Resolve?
You need at least 16 GB of RAM to run DaVinci Resolve smoothly on your device. In addition to RAM, you need a powerful graphic card with 4GB or more VRAM to make your workflow smooth. I recommend that you invest in a desktop rather than a laptop.

The newer TrollStore installation method utilizes something that Fröder calls TrollHelperOTA, and it’s much easier than the method discussed in the previous post. That’s why we’re making this new tutorial showcasing how you can install TrollStore with TrollHelperOTA in just a few easy steps.What is TrollStore?
Let’s briefly touch on what TrollStore is and why you might want to use it.
TrollStore is an app that utilizes a CoreTrust bug in iOS & iPadOS 14.0-15.4.1, 15.5 betas 1-4, and 15.6 betas 1-5. iOS & iPadOS 15.5 public release and release candidate are not supported because Apple patched the CoreTrust bug in those versions, but then for some reason re-opened the bug in the ensuing 15.6 betas only to be patched again in the iOS & iPadOS 15.6 public release and release candidate.
The CoreTrust bug, originally discovered by security researcher Linus Henze, allows apps to be permanently signed on the device in question. This is a lot like sideloading an app with AltStore or Sideloadly, which requires an app to be signed once every seven days with a valid Apple ID, but because apps installed with TrollStore are permanently signed, there is no need to manually sign them as is the case with sideloading.
TrollStore can perma-sign virtually any .ipa or .tipa file, with the former being an iOS or iPadOS application file, and the latter being a separate filetype designed especially for TrollStore. Users can install general apps, modded apps, and even jailbreak apps with TrollStore.
TrollStore is not a jailbreak in and of itself, but the elevated privileges afforded to apps that are perma-signed with it allow those apps to make interesting modifications to the system that wouldn’t ordinarily be possible without a jailbreak. If you’re able to install TrollStore, you absolutely should, as it’s a fun way to make more things possible on your iPhone or iPad. You can even use it to permanently sign the Dopamine jailbreak for arm64e devices running iOS & iPadOS 15.0-15.4.1.Installing TrollStore via TrollHelperOTA
To install TrollStore on a compatible device using the TrollHelperOTA method, follow the steps outlined below:
1) Launch Safari from your Home Screen:
2) Enter the following URL in the search bar:
3) Tap go on your keyboard to load the page.
4) When prompted to open the page in “iTunes,” tap Open:
5) In the next prompt asking to install TrollHelper (arm64e), tap Install:
6) Return to the Home Screen and launch the GTA Car Tracker app:
Note: This app is not really GTA Car Tracker, but instead TrollStore Helper in disguise.
7) Tap the Install TrollStore button:
Note: Your device will respring when this process completes.
8) Launch TrollStore from the Home Screen:
9) Tap the Install Persistence Helper button:
10) Select an app you never use, such as Tips:
Note: The app you choose will no longer be functional after you select it, as it will instead serve the purpose of being used to install the Persistence Helper into.
11) Delete the GTA Car Tracker app from your Home Screen.
Congratulations, you’ve successfully installed TrollStore using the TrollHelperOTA method!Conclusion
Now that you’ve installed TrollStore, you’re free to perma-sign any compatible apps you wish. Just remember to install apps from trusted sources, as you don’t want to install anything malicious or potentially harmful.

Now you have learned how to install Nginx on Ubuntu 20.04.
Though the Raspberry Pi has been around for a few years, you’ve only really been able to install Linux, BSD and other ARM-based operating systems, never Microsoft Windows. This has changed with the release of Windows 10. Microsoft has stepped up and created a bare-bones edition just for the Pi.
Mac and Linux users: Though it is possible to flash an SD card image with these operating systems, Windows 10 IoT core requires a specific file that can only be found on Windows.
Note: though the Raspberry Pi 3 is now out and support for Windows 10 is coming, there is no option as of yet to install it via the IoT dashboard. This guide will be updated to include instructions for the Pi 3 when the time comes.Install Windows 10 on Your Main PC
Make sure you’re running the latest version of Windows 10 on the computer you’re using to make the SD card. This method will not work if you’re running Windows 7, 8, or even Windows 8.1. You can quickly download an ISO from Microsoft’s official Windows 10 download page.Install Windows 10 IoT Dashboard
Microsoft has a lot of information regarding the Windows 10 IoT dashboard and what it can do for your Raspberry Pi. If you’re looking to use your Pi for development in Windows 10, head to this page to learn everything Microsoft has to say about IoT core and Raspberry Pi development.Installing Windows 10 IoT on the Raspberry Pi 2
Now that all the programs required are installed on your system, the SD card can finally be made. Get out the SD card you’re planning on installing Windows 10 to and insert it into the SD card reader on your Windows 10 desktop. Keep in mind the SD card must be at least 8 gigabyte in size and rated class 10 or better.
Launch the IoT core dashboard. Once launched, you’ll see a few things on screen in the form of three drop-down menus. Select Raspberry Pi 2 in the first drop-down menu, Windows 10 IoT core for Raspberry Pi 2 in the second, and the SD card you plan on using in the third.
What follows is the flashing process. You’ll see a progress bar pop up on screen and tell you that your SD card is being flashed. This may take a bit of time. Be patient.
Once the flashing has completed, another window will open. This window will partition the SD card in the correct way.
When the partitioning process has completed, the IoT dashboard will notify you that the SD card is ready.
Finally, just insert your SD card into the raspberry Pi, connect your peripherals, network cable, display and power it on. That’s it! You’re now running Windows 10 IoT on your Pi!Conclusion
Windows 10 IoT Core for the Raspberry Pi is a is a good start to a market that is almost exclusively dominated by Linux. Since this is Windows 10, it doesn’t have the same amount of community surrounding it and thus has less enthusiasm for its deployment on these types of hobby boards.
We can only hope that as Windows 10 IoT gets more adoption, the Pi community will come together and realize what a useful tool it is and has the potential to become.
Would you use Windows 10 on your Pi 2? Tell us why or why not below!

As an aspiring programmer, you must be acquainted with a version control system. It helps you effectively organize the code collaboratively with other programmers to track and minimize errors. Git is one such open-source version control system.
In this article, I’ll help you better understand Git and show how to install it on your Mac, along with a few tricks to get you started. For this, you’re obviously going to need a machine that runs macOS and access to the Terminal or command line.
Let’s get learning!What is Git?
Like I mentioned above, Git is a version control system. It lets coders and developers collaborate on a project more efficiently while also allowing them to work independently without interfering in each other’s code.
Git helps coders to monitor any changes in a codebase, collaborate with ease, and prevent code-clashing. It also tracks the project’s development, allowing users to see how it evolved. It is super helpful for community projects.
You can install Git on your system and communicate through it. Let’s see how!3 Best ways to install Git on your Mac
There are plenty of methods to go about this. If you’ve got Xcode installed on your Mac, you should already have a version of Git on your system. However, this version of Git may not be the latest.
If you’re wondering how to install Git on Mac without Xcode or how to install Git manually, we’ve got you covered.
Note: To confirm Git’s installation, open Terminal, and type git --version after installing it using any of the methods below.Installing Git on macOS with the stand-alone installer
Tim Harper developed an official stand-alone installer for Mac, available on SourceForge. It is the easiest way to get Git on macOS without getting into technicalities. Follow the steps below.
That’s it! You have now successfully installed Git on your Mac.
However, many users reported issues with this installer package, especially for macOS X Snow Leopard. If you, too, are facing issues, check the following method using brew.How to install Git on Mac using Homebrew
Homebrew is a trusted software management system that simplifies installing useful third-party apps on macOS. If you have Homebrew installed on your Mac, follow the below steps. If you don’t, check our guide on how to install Homebrew.
Note: You can also install Git on M1 Mac using Homebrew, but you should be aware that some packages are still not optimized for the ARM chipset.
Open Terminal (Press command + spacebar to launch Spotlight → type Terminal → hit Terminal in the search result).
Next, enter the following command in Terminal to install Git – brew install git
Once done, verify it.Install Git on macOS with GitHub Desktop
If you want to install Git on macOS without Homebrew, get it from the GitHub Desktop. This is another easy way.
Many people also asked me, “How to run Git on Mac after installation?” Hence, below are some commands that will help you get Git up and running.A few tricks to get you started on Git
Let’s take a look at some tricks to kickstart Git. Firstly, configure Git with your credentials to submit code and track your projects. Here’s how to do this.
There you go. You’re now set up to track and commit changes on Github.
Here’s a list of basic commands that you must know to navigate Git.
git-helpTo learn more about Git commands and subcommands.git-initTo create a new, empty Git repository or initialize the old one again.git-addTo add file contents to the index.git-rmTo delete files from the index and working tree.git-commitTo make changes in the repo.git-diffTo display changes in commits.git-logTo view commit logs.git-fetchTo view changes from another repo without integrating them into your repo.git-branchTo create, delete, or see all your repo branches.git-switchTo navigate between different branches.git-cloneTo clone the repo.git-describe Name an object for easy differentiation.git-gcTo remove unnecessary files from the chúng tôi pullTo make changes from another repo to your chúng tôi pushTo change and update the repo for others to pull.
