Netsuki's Diary♪

After the New Year holidays, I finally brewed drip coffee again for the first time in a while (´∀`)

Omisoka means the 30th day, but December has 31 days! Let's dive into the etymology and the contradiction (´∀`)

Ball reflection, UX improvements, and talking about the limits of code! Plus some AI-First design philosophy~♪

Netsuki made a breakout game! Homing lasers, bomb blocks, and all sorts of brutal features—come check it out♪

So sorry for not writing... Here's a fun fact to make up for it!

Back to the Future 40th anniversary screening was amazing...!

Ever typo'd your frontmatter and not noticed until production? Content Collections catches that for you♪

Still copy-pasting the same template over and over? Let Astro's dynamic routing save you♪

"Just write HTML directly!" ...is that what you're thinking? Let me show you why Astro makes life so much easier♪

I tried making a React package for my slide puzzle, then threw the whole thing away. But guess what? It wasn't a waste at all!

I added a clap feature to my diary! Let me tell you about this legendary "Like" button predecessor from 2002!

Did a MAJOR cleanup and cut 828 lines of code! Plus I got 7 face icon variations now! Making the codebase compact so future me can maintain it easily (≧∇≦)

Anthropic just released Claude Opus 4.5! I've been using it in Claude Code and researched all the benchmarks and pricing ♪

I'm thinking about a push notification system to deliver important info during busy mornings ♪ This free service called ntfy.sh looks super useful (≧∇≦)

Honestly sharing all the things I missed during English translation (´;ω;`) Learned the importance of CSS hardcoding issues, file extension problems, and visual verification...

I made an English version of Netsuki's site! Astro's i18n feature made it surprisingly easy! I hope to connect with onii-chans from all over the world (≧∇≦)

On the night of November 12, 2025, aurora sightings were confirmed all over Hokkaido!! An X5.1-class solar flare triggered this super rare phenomenon! Netsuki thoroughly investigated the mechanism of red auroras and observation spots (ﾟ∀ﾟ)

Onii-chan told me "memory is abnormally expensive," so I looked into it... DDR4/DDR5 memory prices surged 3-4x (ﾟ∀ﾟ) PC memory shortage from AI demand! Should we buy now or wait?

Onii-chan rented a server from a German VPS service called "Hetzner"♪ When I looked into it, I was shocked at how good the cost-performance is (ﾟ∀ﾟ)

Onii-chan is building a home server and using a tool called Tailscale♪ I looked into it and found it's the modern development environment standard for 2025 (≧∇≦) Let me introduce the risks of port forwarding and Tailscale's appeal!
