About 11 months ago i revived the amazing but unfortunately unmaintained spotify-tui. Since then I have been working on it almost non stop, finding a lot of problems on the way.One of the main issues I ran into were the Spotify web API rate limits. Third party clients like spotatui are dependent on a developer app made in the Spotify developer dashboard, which get rate limited a lot and Spotify has slowly been deprecating endpoints from it. The workaround for this used to be using a shared client id from ncspot but unfortunately that got rate limited too. This is when i started adding other playback sources, including YouTube, Navidrome&#x2F;Subsonic, Internet radio with +- 30.000 stations, local files, Qobuz for lossless audio and Apple Music for macOS only where it controls the music app remotely.I fixed both the deprecated endpoints and the rate limits with one solution. It still uses librespot in the back, my spotatui specific fork, but gets all data from it instead of only playback. The data comes from the internal API of the official clients, that API gives metadata, playlists, the user library, devices, lyrics and audio analysis. For searching it uses Pathfinder, the internal GraphQL API.There are no web API rate limits because there is no shared app quota. Every user uses their own session as if it was the official client. The only potential problem is that Spotify does not document this API so any change on their side would break it. I intend to fix any of those issues as soon as they pop up.It all started as a TUI back in 2019 but since then I&#x27;ve added a GUI to it too. The GUI is still a bit behind the TUI in terms of features, it only ships Spotify for now, but full parity between the TUI and GUI is coming soon. After that full parity with the official client is next. That is also why I made the GUI looks almost the same as the official client. That way its easier for me and users to find missing features.Spotatui also has lua scripting support, a optional Web companion on spotatui.com, and if you have a AI coding agent like ChatGPT codex or Claude Code you can enable the MCP tools, which lets AI become your personal DJ just by talking to it.Its written in Rust, uses ratatui for the terminal UI and Tauri 2 for the GUI. The Rust core starts a small web server with localhost that only your pc can reach which the GUI then serves. Both frontends share the same playback logic, the same login and the same Spotify code. The only difference is how you interact with it.On first launch it opens a web browser where you need to login with your Spotify premium account (premium is not optional), that is the whole setup done. I would love any feedback about bugs you encounter or features you would like to see.

Existing benchmarks measure solve rate and token output&#x2F;cost, but don&#x27;t punish excess code, which makes a codebase harder to work with in the long term. I wanted to measure this since it matters most for long-term projects.Method: it takes the patches that benchmarks already publish (DeepSWE, SWE-bench Verified, SWE-bench Live) and counts &quot;coding units&quot;: syntax elements like statements, calls, names and literals. I didn&#x27;t use lines of code, so cramming code isn&#x27;t rewarded. Deleted code is subtracted, so it measures net units.GPT-6 and Claude 5.5 have no public patches yet, so I ran them myself on 3–10 tasks on my own subscriptions (shown as faded circles, not ranked).Any feedback or model contributions are welcome, especially public patch exports for newer models.GitHub: <a href="https:&#x2F;&#x2F;github.com&#x2F;La5u&#x2F;Parsimony" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;La5u&#x2F;Parsimony</a>Not affiliated with any of the benchmarks.

I&#x27;ve been playing around with a new kind of isomorphic music keyboard that uses a base-12 notation, and wanted some sheet music to learn some new music for it.The idea is to represent each note in 12-TET as a number, so N ∈ (0,1,2,3,4,5,6,7,8,9,X,Y).I used codex to build a music score rendering backend based on MuseScore with custom note heads that display the pitch class of each note.I&#x27;ve found it pretty helpful for learning how to play my own instrument, so wanted to share in case anyone else was interested.

Character.ai has initiated voluntary Chapter 11 bankruptcy

Hey Hacker News! I&#x27;m Eric, the founder of Consus. We route all AI requests to ITAR restricted and controlled unclassified information (CUI) compliant infrastructure.
Consus itself satisfies ITAR restrictions, and we recently completed our FedRAMP equivalency audit against the 410 FedRAMP High controls. FedRAMP High is the U.S. government’s strictest security baseline for cloud services handling sensitive unclassified data. A breach of this data could cause severe or catastrophic harm. Achieving FedRAMP equivalency, or authorization, is required before processing CUI information.Demo: <a href="https:&#x2F;&#x2F;youtu.be&#x2F;6MYxJe6P4oY" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;6MYxJe6P4oY</a>Aerospace and defense is experiencing rapid growth. Unfortunately, most companies are struggling to use AI because of necessary data protections &amp; compliance risk. These companies can move even faster if they could use the AI tools that most other industries take for granted.I spent most of my career prior to Consus in aerospace &amp; defense. I launched national security payloads at SpaceX, and was an early employee at Castelion. I’ve watched first hand how compliance red-tape makes it difficult for companies to adopt new technologies and trust vendors that touch their sensitive data. For example, I worked with a satellite manufacturer that doesn’t allow any AI tools, even for non-sensitive work.Even as AI has become extremely useful over the past 9-12 months, I was surprised by how many aerospace &amp; defense companies refused to touch it. They could see how it could be helpful, but they were scared about model providers training on their data, violating an ITAR rule, or risk losing new business because of a failed cyber assessment. These are all rational fears.There were a lot of ways to solve some&#x2F;all of these problems, but we focused on building a compliant AI inference layer that can &quot;plug&quot; into any AI tool or workflow. Just as OpenRouter integrates with most tools, Consus can connect to tools like ChatGPT or Claude, open source tools including the Pi coding agent or Open WebUI, or integrate with applications built and maintained by individual organizations.Almost no aerospace &amp; defense company lives in all three major GovClouds (AWS, Azure, Google). When I mapped where frontier models can legally run for ITAR and CUI work, each provider had some subset of models, and each model achieved varying levels of compliance. Our customers don’t think in terms of cloud providers. They think about the data controls they require, and the model they want to use.
That is why we built the compliance suffix. Under the hood, every request hits a single OpenAI-compatible endpoint, where keys are verified and policy is enforced before anything touches inference. Every model name must carry a compliance suffix, such as gpt-5.6-sol:fedramp-high or claude-opus-5-5:itar, and any bare model name is rejected. We never proxy to the standard commercial endpoints.Our customers are also able to build an allowlist of models, and assign spend &amp; model restrictions to individual users in the organization. This is all handled through our Consus Portal where teams can manage spend, keys, and policies.A typical question we hear is why not just use Bedrock in AWS GovCloud or Azure Government directly. For small teams, just getting access to these platforms is difficult. For larger organizations, GovCloud lets you inherit some but not all of the controls needed to handle sensitive data. Also, models are split across providers: GPT-5.6 Sol is only available in Azure Government, while Claude Opus 5.5 is served through Bedrock in AWS GovCloud. If you want both, you are standing up and securing two separate government cloud environments. We run all of them behind one endpoint so customers don’t have to pick a cloud, and we handle the compliance work for each one.Given the data sensitivities, Consus does not store any customer data at rest. All prompts and completions stay in memory only for the length of the request and are never logged or written to disk. Zero data retention is strictly enforced both on ourselves and the infrastructure&#x2F;model providers. We do keep metadata on each request and response for billing and audit purposes.Consus is not self-serve by design. ITAR requires us to know exactly who is on the other end of every key, so we verify every organization and put a contract in place before issuing API keys. We charge our customers a compliance fee starting at $40&#x2F;mo&#x2F;seat plus AI tokens at cost.We are actively serving customers, and would love any feedback from security experts, or developers&#x2F;engineers working in highly regulated industries!References:
