Due to increasingly annoying YouTube ads that Adblock Plus can no longer block, I switched to using uBlock Origin (the most powerful YouTube ad-blocking extension in the world, bar none). However, the Google Chrome Store no longer allows its installation because uBlock Origin is based on Manifest V2, and Chrome is phasing out Manifest V2 extensions.

Moreover, uBlock Origin has no plans to upgrade to Manifest V3. Its alternative extension, uBlock Lite, is based on Manifest V3 but is not as effective or feature-rich as uBlock Origin. If you don’t mind the limitations, you can install it as a replacement.

Google will officially stop supporting Manifest V2 from Chrome version 139 (June 2025). Therefore, I have decided to stick with Chrome 138 indefinitely.

Below, I will share how to install uBlock Origin on Chrome, even though it is no longer available in the Google Chrome Store.

It’s already 2025, and I’m just starting to research AI infrastructure providers. It feels a bit late. My main purpose in this research is to see if there are opportunities to participate in this AI wave.

AI infrastructure services are categorized into providing technical services and solutions, IaaS services (offering GPUs), PaaS, and SaaS services.

Service providers that want to offer technical services and solutions require strong marketing and sales teams. However, those providing IaaS, PaaS, and SaaS products do not need as many marketing and sales resources.

Major cloud providers are already well-established in offering AI-related services, but the emergence of new startups suggests new market opportunities. I am more interested in AI infrastructure startups catering to researchers, small businesses, and developers.

Becoming a technological investor or a user of technology is the easiest way for us to benefit from the AI era.

Recently, I’ve been thinking 🤔. In the current economic landscape, AI is the only growth point, and going with the flow might be easier. So, how can I find my place in this era?

My thought is that AI is a universal technology, just like electricity, computers, and operating systems. Not everyone needs to work in these foundational services, but rather find a position in the ecosystem built on top of them.

Wu Jun once said that, in the future smart era, only about 2% of the population will truly benefit from technological advancements, and these three types of people will enjoy the benefits brought by technology:

1. Those who own core technology
2. Those who invest in core technology
3. Those who apply technology

No tutorials or books needed, master a new language in 1 day (not for 99, not for 9.9, just if you’re willing to use it – classic sales pitch). This isn’t a dream, and it’s not an ad! AI models make learning a new language in no time possible.

Of course, this statement is a bit exaggerated. What I mean is that in the AI era, we no longer need to learn a new language the traditional way—learning first and then practicing. Instead, we can learn directly through practice.

This is my reflection after using Cursor for one month to learn front-end development.

Wake up, AI programming is not as simple as you think. Don’t blindly trust AI-generated code, current AI programming is not as good as you imagine.

I am a frontend novice. I spent 20 hours using Cursor to do secondary development on an open-source website project. After a flurry of activity, I found that none of the features were working anymore. And this open-source project was just a simple webpage website program.

This was my first time using Cursor as a novice. I had previously only used it as an auxiliary tool. My blog’s video playback page was written using V0 dev, the interface was refined using Kimi, and the video list page was written with Cursor.

While research CNI recently, I recalled an interesting issue I encountered during the development of network plugins and investigation of Calico: Calico assigns IP addresses to its own components’ Pods (e.g., calico-kube-controllers). How does Calico achieve this? From the installation of the Calico network plugin to assigning IPs to its own Pods, what happens at the underlying level?

This essentially poses a “chicken-and-egg” problem: running a Pod requires the CNI plugin, while the CNI plugin’s operation depends on the proper functioning of other Pods.
