Getting Serious With LLM Assistance

Great to be back writing the blog. I have just recently (yesterday) updated the blog with a new design template. To my surprise, the switch was effortless thanks to Claude Code. Found a few templating stuffs I wanted to make changes for and Claude did this impeccably. In actual fact, Claude Code has been a main stayer in my day-to-day coding work. I took out a 15 inch portable monitor just for it and positioned it below the primary monitor. The second monitor serves as the Claude Code terminal. This helped a lot, the focus now is bounded to the second monitor in comparison with multi tasking with the primary monitor only. The primary monitor now becomes a monitoring monitor of Claude Code changes. ...

SleekChat: Research to Production in 1 Week

This is a writing about getting things done more than it is a showcase of a new business and the tech empowering it. Within this, an attempt to explain the why will also be written. But before all that, I’m going to try to look cool first so get ready for some cringe moments. Vibe Coding Hell yeah! But not in a way most will vibe with. Being a backend guy, giving up control is not my nature although the web frontend is vibed. As with any experiments, it started with an idea then proof of concept, hit walls then pushed through. Here are the core tech stack to build SleekChat: ...

Meet Broto: An AI Assistant For Kids To Learn

It’s that time again when I learned about something that triggers my curiousity and make it useful. This time that thing answers you back and that’s an LLM or a Large Language Model. I was late to the AI hype because I haven’t found a specific use case that is interesting for me. Now I have, it’s called Broto. How It All Started At work, we have a need to deploy an LLM to automate some of the stuffs we’re cooking with. That was months ago and ended up with a no go because it’s too easy to fool the LLM. Forgot about it and just recently started working on it again. To my surprise, it worked now, fool proof. ...

Building an API in 2023

This blog post is actually taken from my pet project DNSDig’s README.md file. I’m putting it here because I like what I wrote about it. DNS Dig API A project to learn about DNS in Python while investigating what it’s like to build an API in 2023 with FastAPI, Pydantic and DNSPython. Authentication and authorization is handled by Kinde. Getting Started Python 3.11 is required to run this project. If you don’t have it installed, you can use pyenv. ...

Yet Another Unraid Build

Why right? Short answer, I had 2 server builds and 1 of them smoked in the literal sense. Smoke was coming from the CPU socket and I had to put the air purifier in max to get rid of the awful smell. It was supposed to be a ProxMox build to host all of my VMs in my home lab. What an epic fail! Smoked Build It was my first time ever building PCs that went horribly wrong. But the good news is I can salvage most everything from the build except for the PSU, CPU, Motherboard and GPU. I remember I had a slip of the fingers when I was installing the GPU into the motherboard but I was sure I didn’t knocked any components in the GPU. To be safe, I wrote off that old Quadro GPU. ...

High Refresh Rate HiDPI For 1440P Screens On Apple Silicon Macs

Boy this was a rabbit hole necessary for my eyes and their well being. I have 2 monitors and both of them are 1440p Ultrawide and 1440p Super Ultrawide. Out of the box, Apple Silicon Macs doesn’t rate these monitors as HiDPI, external monitors are rated as HiDPI if it’s at least a factor of 2x. What is the cheapest and straightforward solution to make 1440p monitors as HiDPI? This post answers that question. ...

Hackintosh: Virtualized VS Bare Metal

It’s been a few days since my last blog post about a virtualized hackintosh, I’ve got some time to tinker and form opinions and gather facts about it. It’s not bad at all but it comes with a compromise, let me try to follow up on what I’ve written before. Why Virtualize At All? Why not? But a more convincing argument is because I have a gaming PC with a 16 core/32 thread CPU lying around. It’s rather fiddly to dual boot between macOS and Windows because both my GPUs (Radeon RX 570 and RTX 3080 Ti) are connected to my monitors and on Windows this is not ideal. The best possible experience is to use an HDMI or DP switch to connect the GPUs to my monitors, I don’t have such a device and I’m pretty sure I don’t want to explore the quirks that comes with using it. ...

Virtualized Hackintosh and Gaming PC

I have installed hackintoshes since the very beginning on a Core2Duo laptop. Back then the term was OSX86 and the only way to get the OS is through torrent downloads. Since then I’ve built hackintoshes especially when Intel Macbook Pros are so pro. I can’t believe all these years I never tried to do the virtualization route. The past few years, my hackintoshes were always a dedicated PC separate from my gaming PC because Nvidia GPUs have no hope in hackintoshes, now it changes. ...

Noiseless PC Audio

The first experience I had listening high fidelity music involved a Creative Sound Blaster Audigy and a 5.1 Creative speaker setup, this was back in 2003. At the time, I just plug analog outputs to the appropriate speakers, there was no noise or distortion distinguishable from the speakers. It’s a different story today, analog outputs are noisy and your speakers will bleed the electrical noise into sonic waves. A while ago I wrote about Airplay for listening but after a while I wasn’t enjoying the sync delay every time I play any video file. This also doesn’t work with Windows PC so I wanted something that works using a universal standard even though if I have to buy some more toys to do any signal conversion as long as it stays digital all the way to the DAC. ...

Microsoft Flight Simulator 2020 - What I Found So Far

Since the game launched in August 2020, this has been the game I spent time the most with over than 463 hours logged so far. Becoming a pilot was what I wanted to be before I knew how to code, learning to fly is nothing like coding, bugs are fatal. This write up sums up what I’ve found about the game so far I wish I knew before playing the game. ...
