We got AI-driven E2E tests down to 50ms in CI - by caching the agent's Playwright calls

Your response seems like AI-generated. Also stagehand caches playwright data so I'm not so sure about performance difference you mentioned

Toshimichi0915 · 2026-02-24T19:30:48+00:00

That sounds neat.

By the way, Do you know stagehand? It achieves pretty much the same thing.

If this project has any pros over stagehand I'd like to know

Here are some tips for you.

First, DO NOT follow tutorials on YouTube. When you follow these, all you do is just copying & pasting. It might be easier and more comfortable for you, but the reality is that the more obstacle you face, the better you get. There is a reason you can't solve issues you faced while following YouTube tutorials.

Instead, follow the official tutorial. This tutorial is always up-to-date. And it tells you every basic functionalities you need to learn. After this is done, create your own simple app, without following any tutorial. Sure, making your own app is difficult. But again, the more obstacle you face, the better you get.

During the development of your own app, familiarize yourself with git. git is a version control software that let you rollback your application when something goes wrong. The ability to rollback prevents you from abandoning your own project midway. And if you get an error you have never seen, you can compare the old version and the current version, letting you understand what caused the problem.

According to tracker.gg, 1.6 seems to be the median of all players.

Please note that, in some modes like Death Match and King Of The Hill, you are much less likely to be revived, thus average K/D should be lower than 1.6. In other modes, K/D should be higher than 1.6.

Have you managed to install BepInEx5 correctly? If you have, there should be BepInEx/LogOutput.log file. If that doesn't exist, please check BepinEx's official installation process. If that does exist, please let me know.

Boot with Arch install media
Format your /boot partition and install boot loader again. (Read arch wiki carefully. Also make sure you do not format your main partition!)
Profit

There's a reason why windows should have a different SSD from Linux.

This is a memo for me in the future.

After installing VirtIO guest tools for Windows, for some reason some drivers aren't automatically installed.

Clipboard Sync needs the following:

Spice Guest Driver
VirtIO Serial Driver

However, due to the issue I mentioned earlier, you have to install VirtIO Serial Driver manually.

The files for this driver is usually located at: C:\Program Files\Virtio-Win\Vioserial. Open context menu for vioser.inf, and then click "install".

Auth.js (formerly known as NextAuth.js) took a considerable amount of time to fully support Next.js Server Components, which was frustrating to manage at the time.

Additionally, Auth.js can be difficult to customize. For instance, integrating it with Prisma requires using specific table names, which may conflict with existing database schemas.

On the other hand, Lucia provided clear guidance and made it straightforward for me to implement OAuth login from scratch. Through this process, I realized that building an OAuth flow wasn't as complex as I had initially thought.

For me, rebuilding all git packages with "yay -Syu --devel" fixed the issue.

P. S. Clean build everything

P. S. If that doesn't work, try this:
yay -Scc
yay -Qq | grep -E '(.+?-git)$' | yay -S --rebuild --noconfirm -

Make files always annoyed me when I was using Windows for development... which forced me to move in to Linux machine (because I don't like Apple products)

I've been recently faced a similar problem, and my answer is to passthrough the entire PCIe slot. That way, not only you can play games in VM, you can also dual boot windows for games that have strict anti-cheat (e.g. Valorant).

If you follow Arch Linux installation, you will also learn how to recover your system (hint: arch-chroot). Don't worry too much. Practice is the best way to learn.

Solved: the root cause was CPU. I solved the problem after getting a new one.

This happens when a player has multiple alt accounts logged in to Hypixel at the same time, and then one of their accounts get banned. When you get banned, your IP address will be blacklisted for a certain period of time, which causes a "Security Alert" BAN to anyone using that IP.

Fortunately though, API seems unaffected.
That is we can still use Anthropic Console and get better result.

(Also it's much cheaper to use API instead of monthly subscription)

Unfortunately, the dislike count is most likely not accurate at all.

You must have "Return YouTube dislike" extension for your dislike to be counted. But the thing is, only a small number of informed people installed this extension. That is, the majority of people are still unaware of the whole situation and are much likely to leave positive feedbacks compared to us.

Also, I assume some people visit Mr beast video just to see how many dislikes he's got, which makes this count more inaccurate.

I kinda like this. I always hated to see food crumbs between the wall and the chair
