The Cub's Lair

With the explosion of local Large Language Models (LLMs) and multimodal AI architectures (such as Flux and Stable Diffusion), the staggering demand for VRAM—often reaching tens of gigabytes—leaves single-card users in a tight spot. To keep the budget from skyrocketing, a highly pragmatic and cost-effective workaround is mixing cross-generational GPUs to extract maximum value from existing hardware, forging a high-performance 32GB VRAM private AI matrix.

This post outlines the entire lifecycle of migrating and upgrading an existing rig from an ASUS AP201 Prime Case to a Lian Li 217 vertical airflow chassis, topped off with a battle-tested “Hardcore Gotchas & Troubleshooting Guide.”

Long time no see, my blog.

Hi, I’m Little Flyer Bear (lfbear). Welcome to my lair. This a place where I’ll post some of my own feelings and some technical articles.

Background

This article aims to introduce a viable implementation of GitOps through a practical case study based on GitLab and ArgoCD.

This setup is ideal for teams looking for a lightweight, rapid container deployment workflow. If you are seeking a fast and simple deployment method for projects running in Kubernetes (K8s), GitOps is an excellent choice.

Typically, our source code is managed by version control systems (VCS) like GitLab. In recent years, as GitLab’s built-in CI has become increasingly robust and user-friendly, GitOps has become much easier to adopt.

My blog hasn’t been updated for over a year. Truth be told, I went through a lot in 2019 and had so many reflections. But every time I wanted to write, Jekyll’s friction made it a hassle to use, so I kept putting it off.

Then, during the 2020 Spring Festival, I stumbled upon Hexo and my eyes lit up. The ecosystem is so vibrant and thriving! I spent a bit of free time over the weekend writing a script to migrate all my past posts, and it worked like a charm.

Here are a few frequently used Hexo commands to save my future self from forgetting them the next time I write:

hexo new [layout] <title> # Create a new blog post
hexo clean                # Clean generated cache/static files
hexo g                    # Generate static files
hexo s                    # Start the local server

Let’s test it out and see if it’s as convenient as it looks. Also, a huge shout-out to Travis CI for providing their free CI/CD build services—with the size of my blog, it builds in under a minute.

I had been wanting to move over here for a long time, but never had the time to mess around with it. I finally decided to get it done during this holiday break. This blog has so many years of history, and whenever I migrate or tweak things, I always want to make sure I don’t lose any data. I didn’t expect the migration process to be this seamless, especially with Jekyll and GitHub Pages’ custom domain binding and automatic SSL certificate generation. Super awesome!~

For quite some time now, I’ve felt this holiday having less and less to do with me—honestly, today’s date (September 11th) is far more memorable to most people. But this year, the sudden influx of holiday-related feeds caught my attention, putting me in the mood to reminisce about my past teachers.

Looking back, though the vast majority were mediocre and narrow-minded—especially during my childhood—there were indeed a select few who truly deserved the title of “mentor.” This was particularly true during my university years and after entering the workforce; ironically, the “teachers” at this stage of life are the ones who contributed most meaningfully to our personal growth. Being just a few years older, they shared their hard-earned life lessons with us. Despite the slight age gap and differing views on certain matters, their guidance was incredibly valuable.

Honestly, I don’t hold the teaching profession in high regard. The reason is simple: they are “tirelessly destroying” rather than “tirelessly teaching” (a pun on huiren bujuan). Low educational background, poor personal qualities, overly worldly-wise, and obsessed with petty office politics—this is my general impression of most teachers I’ve encountered.

Much like doctors, perhaps due to systemic issues in our society, our teachers are a far cry from what teachers should be. Combined with the traditional guild-like master-apprentice mentalities, it has made the education sector deeply unpopular. Looking at them, you can barely see any hope or future for society.

Ten years ago, by pure chance, someone gifted me a .com domain. Even though domains weren’t super expensive back then, as a broke student, there was no way I was going to splurge on buying one myself.

However, they only paid for one year. When it expired, I couldn’t afford to renew it, so it got snapped up by domain squatters.

Later, after I started working, even though I had the money to register other domains, I could never quite forget my very first domain. This year, I finally bit the bullet and bought it back from a foreign domain broker.

I won’t bore you with the details of the process, but it involved a lot of haggling (turned out foreigners like a good story too!). In the end, I managed to get it back at a reasonable price.

I’m so thrilled. I’ll be using this domain going forward. It feels like a true return to my roots.

P.S. Honestly, foreign domain brokers seem a lot more reasonable than some of the local ones here.

Why do I call these “advanced settings”? Because I kept running into issues where the headset tracking would frequently get lost, yet none of the troubleshooting threads on the internet could fix it. If you are facing the same frustration, this post might save your day.

This is a politically sensitive topic. Why write about it? I have always disliked discussing politics, unless it has deeply and directly affected my personal life.

Background

Lately, boycotts of “Country X” products and foreign fast-food chains have been popping up one after another, all under the banner of “patriotism.” In reality, many of these brands are highly localized, and their taxes and employment figures have already contributed directly to our “Great Celestial Empire” (大天朝). From a rational perspective, these boycotts are completely pointless. Yet, it is only now that various state media outlets are stepping up to advise people to remain rational. Something feels off here. Who was it that previously used all kinds of patriotic rhetoric to fan the flames of public emotion in the first place? Waiting until now to lock the stable door after the horse has bolted feels incredibly hypocritical.

Definition

Let’s dissect the concept of “patriotism.” Patriotism is something drilled into us from childhood through patriotic education. The official definition (from Baidu Baike) is as follows:

Patriotism refers to a positive and supportive attitude of an individual or group toward their homeland, and is one of the civic virtues an individual should possess.
