tokkyokky··on Show HN: I built a CSV parser to try Go 1.26's new SIMD package
Thanks for the tip! Your comment prompted me to refactor the quote handling - replaced the bit-by-bit state machine loop with prefix XOR, and switched to adjacent bit masking for double-quote detection. Seeing a nice performance improvement in benchmarks. Go's simd/archsimd doesn't have CLMUL yet, but the XOR cascade works well. Appreciate your feedback!

Oh, nice! I’ll try to do it!!
tokkyokky··on Show HN: First Valkey-specific VS Code extension (open source Redis fork)
Got it, thanks! Good to know they're still compatible for now. I'll have to watch how the feature gap develops.
tokkyokky··on Show HN: I made an app that blurs my screen when I slouch
Ah, that makes sense. Good to know iTerm does the same thing. Thanks for sharing the reference!

That's cool! Is this implemented using a Swift feature?
tokkyokky··on Show HN: First Valkey-specific VS Code extension (open source Redis fork)
This is an interesting extension! I thought Redis and Valkey were compatible, but what are the differences between them?

Ah, you're right..
tokkyokky··on Show HN: macOS CLI tool for managing Calendar events and Reminders via EventKit
This is an idea that seems like it should exist but doesn't. It looks useful!
tokkyokky··on Ask HN: Are you going to meetups/conferences?
Yes, in Japan the trend seems to have shifted back toward in-person events. Most meetups and conferences I see now are offline rather than online, definitely more than a year or two ago.
tokkyokky··on Tell HN: Claude helped me maintain my old open source project
Thanks for sharing! The "stay on subject" and git diff workflow tips are useful.
tokkyokky··on Ask HN: What single AI tool/technique 10x'd your productivity last year?
Claude Code for me. The optimization cycle is ridiculously fast – they ship improvements based on user feedback way quicker than I expected. And honestly, Opus 4.5 is smart enough out of the box that I haven't had to mess with configs or prompts much at all.
tokkyokky··on Google Cloud to shut down Memorystore for Memcached by Jan 2029
Feb 2027: Can't create new instances in new projects

Jan 31, 2029: Service fully shut down

Google Cloud recommends migrating to Memorystore for Valkey (Redis-compatible OSS fork). What do you think?

That’s a great outcome for 2 hours. If you’re willing to share, what was your rough workflow/prompt sequence (project overview → reproduce → propose patch → add tests → iterate)?
