Using my Mac or Linux devices feels a bit off too, since they already have their own dedicated tasks. So, I figured I’d put the lab computer to use. Once set up, I can run my training there and keep doing my own thing on my main machine.https://blog.yexca.net/en/archives/286/Tue, 16 Jun 2026 13:07:08 +0900https://blog.yexca.net/en/archives/286/📢 This article was translated by gemini-3.5-flash I used to think locally deployed models could speak completely freely. But after hands-on experience, I realized modern AI models have two layers of shackles: one is the cloud provider’s external filter, and the other is the “refusal neurons” deeply baked into the model weights during safety alignment training. To get the perfect experience, you need to deploy an uncensored model. Warning Uncensored versions generally remove …https://blog.yexca.net/en/archives/285/Sat, 13 Jun 2026 13:02:57 +0900https://blog.yexca.net/en/archives/285/📢 This article was translated by gemini-3.5-flash Back when OpenClaw was super popular, I wasn’t really a fan of using Node for deployment. The subsequent security vulnerabilities confirmed my doubts. Now, there are plenty of great forks. Since I prefer lightweight setups, I went with the lighter ZeroClaw. Since I’m deploying my own AI assistant, I don’t want my data uploaded to the cloud. So, the goal this time is to build a fully local private assistant.https://blog.yexca.net/en/archives/284/Sun, 07 Jun 2026 18:42:10 +0900https://blog.yexca.net/en/archives/284/📢 This article was translated by gemini-3.5-flash A friend strongly recommended Codex to me recently, so I gave it a spin. After trying it myself, I’d call it an “idea extractor.” Before this, my impression of AI coding was that it could build things, but the resulting code would be a mess to maintain. But after actually getting my hands dirty, I burned through 72M tokens in one go. My ideas kept getting pulled out and turned into reality. It was a massive productivity …https://blog.yexca.net/en/archives/283/Tue, 02 Jun 2026 17:23:44 +0900https://blog.yexca.net/en/archives/283/📢 This article was translated by gemini-3.5-flash Completely relying on AI to extract clean vocals is still not quite realistic with current technology; in most cases, manual correction is needed. However, as long as you have enough data, you can always scrape together enough AI-extracted vocals suitable for training. This article discusses a workflow for filtering training audio using only AI, from the perspective of an outsider. Everything used here is open-source.https://blog.yexca.net/en/archives/281/Thu, 28 May 2026 15:52:18 +0900https://blog.yexca.net/en/archives/281/📢 This article was translated by gemini-3.5-flash Set up intranet penetration using frp with a full Docker deployment. Tested the speed, and it’s pretty good with acceptable latency. DNS Configuration You’ll need a server with a public IP. I handle my SSL certificates via Cloudflare, so all my connections go through port 80. Configure a few domains pointing to your server: one for connecting to frp (e.g., frp.example.com), and others for the services you want to proxy (e.g., …https://blog.yexca.net/en/archives/280/Sat, 23 May 2026 03:00:06 +0900https://blog.yexca.net/en/archives/280/📢 This article was translated by gemini-3.5-flash Getting Audio For training, real lossless audio is highly recommended (specifically pcm_f32le WAV files). It’s best to rip them from physical albums. You can refer to this guide: https://www.bilibili.com/opus/925630344961458181 , but skip the FLAC conversion and export directly to WAV. This guide uses Applio (based on the RVC architecture). You’ll need about 10 to 60 minutes of clean vocals (acapella) to get good training …https://blog.yexca.net/en/archives/276/Wed, 15 Apr 2026 09:27:01 +0900https://blog.yexca.net/en/archives/276/📢 This article was translated by gemini-3-flash-preview When it comes to audio and video processing, FFmpeg is the ultimate open-source tool. I’ve been using it for a while, but my notes were scattered. Since I’m using it more frequently now, I decided to compile my most-used commands here (and add a few missing ones).

Fast forward to today. While tinkering with my server, the mount speeds on my cloud drives have been just… disappointing. On impulse, I ordered an N5095 motherboard. I realized the 4GB RAM stick I have lying around is a bit low, but I really didn’t want to …https://blog.yexca.net/en/archives/258/Sun, 05 Oct 2025 01:58:35 +0900https://blog.yexca.net/en/archives/258/📢 This article was translated by gemini-2.5-flash Introduction Google’s Gemini Pro subscription comes with 2TiB of space, which naturally got me thinking about tinkering again. So, let’s get to it. But looking back, it’s already been three years since my last tinkering . Time really flies, huh? Manga: Komga First up is Komga for reading manga. While scanning can be a bit sluggish, the overall user experience is decent. After all these years, Komga has seen many updates.

Renewed it last year, but this year, with all the deals popping up, renewing felt a bit pricey. After checking out some smaller server providers, I saw Alibaba Cloud offers discounts if you’ve been bill-free for 12 months. Since I was already looking at big names, Oracle popped into my head. Figured I’d give it a shot. Used all my real info, and it actually got approved directly.

Browser downloads were unstable and kept failing, so I decided to find a way to get direct download links. Extension Issue I initially thought the IDM extension was no longer supported and needed a reinstall. But after deleting it, the Chrome Web Store showed it couldn’t be installed. Well, I deleted it too early.https://blog.yexca.net/en/archives/199/Fri, 22 Nov 2024 22:05:34 +0800https://blog.yexca.net/en/archives/199/📢 This article was translated by gemini-2.5-flash An old post I wrote, system creation date 2023.12.01.

When I pulled out my ancient setup USB drive, the software inside was pretty outdated—some wouldn’t even run on a modern system, and for others, I’ve found better alternatives. I’m writing this article to document the software I used for this 2024 build.https://blog.yexca.net/en/archives/175/Fri, 26 Jul 2024 22:22:22 +0800https://blog.yexca.net/en/archives/175/📢 This article was translated by gemini-3-flash-preview Introduction After migrating Typecho to a Docker container, enabling HTTPS caused errors when trying to log into the admin panel. It worked fine over HTTP. Since my previous non-Docker deployment didn’t have this issue, I initially suspected a Docker networking problem. At the time, I only needed to make a one-off update, so I just disabled HTTPS, finished the changes, and left it. Now that I’m using Typecho again and …https://blog.yexca.net/en/archives/153/Sat, 17 Feb 2024 22:51:34 +0800https://blog.yexca.net/en/archives/153/📢 This article was translated by gemini-3-flash-preview When did I even write this?

Maybe it’s because things have been too quiet lately and I felt like tinkering, or maybe it’s that “I might not need it, but I must have it” mindset, but I ended up making an impulse purchase.

Now that my server has expired and I’ve moved my blog to GitHub, that’s no longer an option. So, I went looking for a solution. The Failed Attempt Even though it failed, I’m documenting it anyway. I probably just didn’t know how to use it.https://blog.yexca.net/en/archives/114/Fri, 09 Jun 2023 23:32:09 +0800https://blog.yexca.net/en/archives/114/📢 This article was translated by gemini-3-flash-preview Recently, I couldn’t connect while playing Mirishita, so I looked for a solution. (Also testing a Spotify embed—this theme doesn’t support direct H5 parsing, and I’m too lazy to fix it.) Domain 1 theaterdays.appspot.com Originally, a Spotify song by Amayadori was embedded here. I’ve been loving Amayadori’s music lately and listening to them often. On Last.fm, “Nekokaburi” was my #1 track for the past 30 days. But the top …
