skyzouwdev | 6 months ago | on: Show HN: I built a toy TPU that can do inference and training on the XOR problem

This is super cool. The fact that you went in without hardware experience and still pushed through makes it even more impressive. I like the philosophy of trying the “hacky” way first instead of just copying existing designs—it’s probably the fastest path to real understanding. Curious, what was the hardest part where you almost gave up?

skyzouwdev | 6 months ago | on: Show HN: NextDNS Adds "Bypass Age Verification"

That’s a bold move. Handing over IDs to random sites is definitely a privacy nightmare, so I get why you built this. The real question is whether it buys time for users or just accelerates the push for stricter regulation. Either way, it sparks an important conversation

skyzouwdev | 6 months ago | on: Show HN: Code-snippets for developing eBPF Programs

Nice idea — eBPF is powerful but the boilerplate around maps and SEC() sections is definitely a time sink. Do you plan to include inline links back to the kernel docs/specs in the extension? That could make it even more useful as a learning aid.

skyzouwdev | 6 months ago | on: Show HN: Scoped, expiring API keys for AI agents

Makes sense — handing full API keys to agents is a huge risk surface. Even with fake UUIDs at MVP stage, the scoped/expiring pattern seems useful. Curious if you’ve thought about integrating with existing secrets managers (Vault, Doppler, etc.) instead of rolling custom crypto later on.

skyzouwdev | 6 months ago | on: Show HN: Lue – Terminal eBook Reader with Text-to-Speech

This is neat. Most eBook → audio tools I’ve tried either butcher formatting or feel clunky, so a “just throw it in and listen” approach is refreshing. Curious how well it handles footnotes/sidebars in practice — do you skip them entirely or try to inline them?

skyzouwdev | 6 months ago | on: Show HN: YouTube Audio Player

Clever idea — I can see this being perfect for long podcasts or lectures where the video isn’t needed. Curious how you’re handling YouTube’s TOS on this though, seems like it could be a tricky part.

skyzouwdev | 6 months ago | on: Show HN: Play Pokémon to unlock your Wayland session

That’s a really creative take on session locking. I can see it being both fun and surprisingly secure — anyone trying to unlock your machine would need to know the game and the exact sequence. Do you see this as more of a novelty project, or could it be adapted for practical use in real security setups?

skyzouwdev | 6 months ago | on: Show HN: Yet another memory system for LLMs

That sounds like a practical take on LLM memory — especially the block-level deduplication part.

Most “memory” layers I’ve seen for AI are either overly complex or end up ballooning storage costs over time, so a content-addressed approach makes a lot of sense.

Also curious — have you benchmarked retrieval speed compared to more traditional vector DB setups? That could be a big selling point for devs running local research workflow

skyzouwdev | 6 months ago | on: F-Droid build servers can't build modern Android apps due to outdated CPUs

That’s a tough one. It’s ironic that the very platform meant to keep apps open and accessible is now bottlenecked by outdated hardware.

Upgrading the build farm CPUs seems like the obvious fix, but I’m guessing funding and coordination make it less straightforward. In the meantime, forcing devs to downgrade AGP or strip baseline profiles just to ship feels like a pretty big friction point.

Long term, I wonder if F-Droid could offer an optional “modern build lane” with newer hardware, even if it means fewer guarantees of full reproducibility at first. That might at least keep apps from stalling out entirely.

skyzouwdev | 6 months ago | on: Show HN: Turn your iPhone into a local OCR server using Vision Framework

That’s a cool approach. Running OCR locally avoids the usual privacy and latency trade-offs, and turning the phone into a network-accessible endpoint is clever.

Curious about performance — how fast is the Vision Framework on-device compared to something like Tesseract or cloud OCR APIs? And does the app stay responsive if the phone is handling multiple requests at once?

skyzouwdev | 6 months ago | on: Show HN: Inworld Runtime – A C++ graph-based runtime for production AI apps

This is interesting — I’ve run into that exact pain point of spending more time on plumbing than building features.

Curious about the choice of C++ for the core runtime. Was the main driver raw performance, or more about portability and low overhead in production environments? In my case, I’ve mostly worked with Python pipelines and they tend to choke when you try to scale concurrency without overcomplicating the architecture.

The graph-based approach reminds me a bit of Unreal’s Blueprints, but for AI ops. If you can make it genuinely easy to plug in custom nodes without touching glue code, that could be a big productivity boost.

skyzouwdev | 6 months ago | on: Show HN: Aha Domain Search

Just gave it a spin — the direct RDAP lookup from the browser is such a nice touch. I’ve always found domain search tools frustrating when they filter or push certain TLDs, so the “no server” part is refreshing.

The “Quirky” tab is surprisingly fun — got a few name ideas I wasn’t expecting. One small suggestion: maybe add a bulk check option for multiple keywords at once? Would make brainstorming sessions even faster.
