Show HN: Xfer, a data-transfer language
Xfer is an experimental language I've been defining for a little while. It's intended to be a strictly-typed alternative to Json that offers a few other features, like comments, nested elements, placeholder substitution, and metadata. It's in VERY early days, so I'd love to hear your suggestions and feedback.
Show HN: Visual inference exploration and experimentation playground
Most inference UIs that I've come across pretty much just give us a chat-like interface to toy around with models in a single visual conversation thread.<p>Given the fact that we are limited to seeing only one output at a time, it's kind of hard to compare outputs from different models, adjustments made to the prompting, and sampler settings.<p>But even when keeping the generation parameters the same (e.g., to test for reliability in the output) and just going for multiple passes, there is no easy way to have a side-by-side comparison to keep track of the outputs from the multiple "rounds".<p>I really like excalidraw and thinking visually, so that got me thinking: why not build a sort of "open-world" playground to just place nodes that represent system, user, and assistant messages on a big canvas? Since they all fit on the screen, we have this easy side-by-side comparison that is basically unlimited in the number of direct side-by-side threads at any level. Meaning one user input could lead to two assistant outputs that in turn introduce new sub-branches that can be tracked visually.
Show HN: Burner – A low cost wallet to gift crypto
Hi HN! I’m one of the creators of Burner, a low cost Ethereum hardware wallet designed for gifting. After creating various forms of crypto “cash” (<a href="https://kong.cash/" rel="nofollow">https://kong.cash/</a>, <a href="https://offline.cash/" rel="nofollow">https://offline.cash/</a>) we learned that gifting cryptocurrencies was consistently one of the biggest challenges for holders and enthusiasts.<p>Burner looks and feels like a colorful gift card, but under the hood it incorporates a secure element chip. You can access its wallet with just an NFC tap, and it works entirely through our (soon to be) open source web app.<p>There is a lot more to share, like USD II (created by <a href="https://www.bridge.xyz/" rel="nofollow">https://www.bridge.xyz/</a>), a stablecoin that we designed to work with Burner without gas, but for now we’re excited to push Burner out the door and start getting feedback from users.

Show HN: Windsurf – Agentic IDE
At Codeium, we've been building AI-powered extensions for a while (we first launched our VSCode extension with autocomplete a little over 2 years ago!), but we've always thought there would come a day where we would hit the limits of what could be achieved within existing IDEs, so we decided to build our own: Windsurf (yes, it's yet another VSCode fork :)<p>We've stuffed a lot of cool features into Windsurf—a super fast autocomplete model, an inline diff generation experience that feels truly native, but we're most proud of Cascade, which is an evolution of the sidebar chat experience that many other extensions have. Cascade can perform deep reasoning on your existing codebase, access a vast array of tools that allow it to run terminal commands and find relevant files, and it's omniscient of all the actions that the user has taken independent of invoking the AI. (You can for example, start implementing a change manually and just ask Cascade to "continue").<p>We've been using Cascade internally at Codeium on our actual production codebase, and we're getting actual value from it. We hope everyone here does too! You can find a bunch of demos of Cascade on our website but I want to show one that I made myself using Cascade to solve an interesting cryptography challenge:<p><a href="https://youtu.be/LbYepFmVB20" rel="nofollow">https://youtu.be/LbYepFmVB20</a><p>Cascade was able to explain the problem to me, install some libraries needed to interact with the challenge, give me some pointers towards a solution, and implement an attack that I described to it all by itself.

Show HN: Konga Beat – A custom track editor for Donkey Konga 2 and 3
Howdy HN!<p>For those who don't know, back in the early 2000s, Nintendo and Namco developed a series of music rhythm games for the GameCube featuring Donkey Kong called Donkey Konga: <a href="https://www.mariowiki.com/Donkey_Konga_(series)" rel="nofollow">https://www.mariowiki.com/Donkey_Konga_(series)</a><p>The Donkey Konga games borrowed heavily from Taiko no Tatsujin (another music rhythm game by Namco). However, instead of taiko drums, the player would use DK Bongos to jam along with music from different eras and genres.<p>Long story short, I figured out how to add custom tracks to some of the Donkey Konga games (Donkey Konga 2 and 3) but found the entire process cumbersome, so I decided to make a dedicated editor. It was a lot of fun to make, and I hope others get some enjoyment out of it too!

Show HN: Bluetooth USB Peripheral Relay – Bridge Bluetooth Devices to USB
Hi HN! I built Bluetooth USB Peripheral Relay, a tool that lets Bluetooth devices (like keyboards and mice) connect to USB-only hosts using a Raspberry Pi Zero W.<p>Why? My friend needed a way to use his Bluetooth mouse and keyboard on a PC with Bluetooth disabled due to policy restrictions. This tool acts as a bridge, relaying Bluetooth input over USB. It also lets you use Bluetooth peripherals with older devices that only support USB input.<p>Tech: Written in Go, optimized for Raspberry Pi Zero W.<p>I love HN’s community and often lurk here—I’m hoping this project is useful or at least sparks some interesting discussions. Feedback and contributions are welcome!

Show HN: Open-source Kibana alternative for logs and traces in ClickHouse
Hi HN, Mike and Warren here! We're excited to share some (early) work towards our next major version of HyperDX. HyperDX makes it easy to visualize/search logs & traces on top of Clickhouse (so incident & bug investigations hopefully go by a little easier). For example, if a team is thinking of migrating to Clickhouse for their observability data warehouse [1][2][3] usually due to cost or data privacy reasons, they can easily throw HyperDX on top to do the UI layer for analysis and dashboarding in a dev-friendly way (aka not needing to type paragraphs of SQL to find some logs)<p>Over the past year we've seen a ton of excitement in companies adopting Clickhouse-based observability stacks - but one of the biggest challenges we've seen is that the UI layer on top of Clickhouse is either clunky to use for observability use cases (ex. BI tools), or too tied to a specific ingestion architecture to scale to every use case (we used to be in this category!). For companies that needed more flexibility in how their data is ingested and stored (usually due to running at a large scale), there's really no good options for a developer experience (DX) focused observability layer on top of Clickhouse (Shopify spent 3 years building it in-house!)<p>Our current release works completely in the browser - and it does this by building on top of Clickhouse's HTTP interface, which our React app can directly talk to. This means you can actually try HyperDX in your browser on your own Clickhouse with no installation! This was fortunately easy for us to accomplish due to being full stack Typescript, making it incredibly easy to shift between server and client code. On top of this we've been spending time baking in performance optimizations to ensure that HyperDX can continue to leverage Clickhouse efficiently at larger data volumes. We do a few tricks like only fetching columns that are needed for the current search, and re-querying to expand the entire row if needed to fully leverage Clickhouse's columnar nature (40% faster, ymmv!) - or rewriting queries to use materialized columns to speed up Map column access when available (10x faster!).<p>On the DX side: we support querying using both Lucene (ex. `fullText property:value`) and SQL syntax. We've found the former to be our favorite for how concise it is. Similarly for charts, our chart builder has been upgraded to accept SQL expressions as well, so you can leverage the full power of SQL, while avoiding typing paragraphs of boilerplate SQL for time series data. We also make it easy to switch between UTC/local timestamps! Lastly, we've added high cardinality outlier analysis by charting the delta between outlier and inlier events (a la bubble up) - which we've found really helpful in narrowing down causes of regressions/anomalies in our traces.<p>We have a lot more planned for the full release - but wanted to get this out early to hear your feedback and opinions!<p>In Browser Live Demo: <a href="https://play.hyperdx.io/search">https://play.hyperdx.io/search</a><p>Github Repo: <a href="https://github.com/hyperdxio/hyperdx/tree/v2">https://github.com/hyperdxio/hyperdx/tree/v2</a><p>Landing Page: <a href="https://hyperdx.io/v2">https://hyperdx.io/v2</a><p>[1]: <a href="https://www.uber.com/blog/logging/" rel="nofollow">https://www.uber.com/blog/logging/</a>
