- However, the maintainers of the project have the authority to approve or reject contributions.
Blocking of Russian Developers
- On March 10, 2022, Linus Torvalds, the creator of Linux, announced that Russian developers would be blocked from contributing to the kernel.
- This decision was made due to concerns about the Russian government’s potential to use the kernel for malicious purposes.
- Torvalds stated that the block would remain in place until Russia “stops the war in Ukraine.”
Reaction
- The block has been met with mixed reactions from the Linux community.
- Some developers support the decision, arguing that it is necessary to protect the security and integrity of the kernel.
- Others have expressed concern that the block could harm the development of Linux and create a divide within the community.
Alternative Options
- Blocked Russian developers can still contribute to Linux projects that are not maintained by the kernel maintainers.
- They can also create their own independent forks of the Linux kernel.
- However, these options may not be as viable as contributing to the official kernel project.
Long-Term Implications
- The blocking of Russian developers is likely to have a significant impact on the development of Linux in the long term.
- It could reduce the number of contributions to the project and create a shortage of skilled kernel developers.
- It could also lead to a fragmentation of the Linux ecosystem, with different forks being developed and maintained by separate groups.
Conclusion
The blocking of Russian Linux kernel maintainers is a significant event that has raised concerns about the future of the project. While some support the decision, others are worried about its potential consequences. The full impact of the block remains to be seen, but it is likely to have a lasting impact on the development of Linux.

What is two-factor authentication (2FA)?
Published: Mon, 28 Oct 2024 09:00:00 GMT
Two-factor authentication (2FA) is a security measure that requires you to present two different pieces of evidence to verify your identity. This is typically done by combining something you know (such as a password) with something you have (such as a phone).
Here’s how 2FA typically works:
- You enter your username and password to log in to an account.
- You are then prompted to enter a second factor, such as a code that is sent to your phone via text message or an app that generates codes.
- You enter the code, and if it matches the code that was sent to your phone, you are granted access to the account.
2FA is a more secure way to protect your accounts because it requires someone to have both your password and your phone in order to log in. This makes it much more difficult for hackers to access your accounts, even if they have your password.
There are many different ways to implement 2FA, but the most common methods are:
- SMS-based 2FA: This is the most common type of 2FA, and it works by sending a code to your phone via text message.
- App-based 2FA: This type of 2FA uses an app on your phone to generate codes. This is typically more secure than SMS-based 2FA, because it does not rely on your phone number being active.
- Hardware-based 2FA: This type of 2FA uses a physical device, such as a USB key, to generate codes. This is the most secure type of 2FA, but it is also the most expensive.
If you are concerned about the security of your accounts, you should consider enabling 2FA. It is a simple and effective way to protect your accounts from hackers.
