Show HN: Datacmd – Terminal-native dashboards from CSV/API in one command Hi HN,

I built Datacmd to eliminate bloated dashboards and browser UIs. It turns any CSV, JSON, API feed into live, terminal-native dashboards with one command. Fast. Minimal. Developer-centric. AND IT'S OPEN SOURCE https://github.com/VincenzoManto/datacmd

What it does:

* Generates dynamic dashboards in the terminal: tables, gauges, pie charts, line charts, radars, text boxes * Layout auto-generated or configurable via YAML * Supports CSV, JSON, REST APIs, live system metrics (CPU, memory, disk)

Why this matters:

* No GUI. Instant visuals where developers live * Zero setup. Download binary or use "go run", and dashboards appear * Great for sysadmins, devs, ops, data hackers working in terminal-first workflows

What I learned building it: Automating a clean layout via algorithm beats manual dashboard design for fast insights. Generating widgets in terminal forces clarity - no fluff, just signal.

Looking for feedback on:

* Performance with massive datasets (>100k rows) * UX: readability, layout transitions, color themes * Widget ideas: real-time alerts, sparkline ring charts, CLI-friendly drill-downs

Live on GitHub. Let me know if you want a downloadable binary or CI build link. Open to contributions, bug reports, wild dashboard ideas.

Show HN: KeyEnv – CLI-first secrets manager for dev teams (Rust)

Show HN: KeyEnv – CLI-first secrets manager for dev teams (Rust) Hi HN,I built KeyEnv because I was tired of the "can you Slack me the Stripe key?" workflow.<pre><code> The problem: My team's secrets lived in a mix of Slack DMs, shared Google Docs, and .env files that definitely weren't in .gitignore at some point. Enterprise tools like Vault required more DevOps time than we had. Doppler was close but felt heavier than we needed. What KeyEnv does: keyenv init # link project keyenv pull # sync secrets to local .env keyenv run -- npm start # inject secrets, run command That's basically it. Secrets are encrypted client-side (AES-256-GCM) before leaving your machine. Zero-knowledge architecture—we can't read your secrets even if we wanted to. Technical details: - Single Rust binary, no runtime dependencies - Works offline (cached secrets) - RBAC for teams (owner/admin/member/viewer) - Service tokens for CI/CD - Full audit trail Honest tradeoffs: - SaaS only, no self-hosted option - Fewer integrations than Doppler - If you need dynamic secrets or PKI, use Vault Pricing: Free tier (3 projects, 100 secrets), $12/user/month for teams. Would love feedback on the CLI UX and any rough edges. Happy to answer questions about the architecture. </code></pre> <a href="https://www.keyenv.dev" rel="nofollow">https://www.keyenv.dev</a>

Show HN: On the edge of Apple Silicon memory speeds

Show HN: On the edge of Apple Silicon memory speeds I have developed open source CLI-tool for Apple Silicon macOS. It measures memory speeds in different ways and also latency. It can achieve up to 96-97% efficiency on read speed on M4 base what is advertised as 120GB/s. All memory operations are in assembly.I would really appreciate for results on different CPU's how benchmark works on those. I have been able to test this on M1 and M4.command : 'memory_benchmark -non-cacheable -count 5 -output results.JSON' (close all applications before running)This will generate JSON file where you find sections copy_gb_s, read_gb_s and write_gb_s statics.Example M4 with 10 loops: "copy_gb_s": { "statistics": { "average": 106.65421233311835, "max": 106.70240696071005, "median": 106.65069297260811, "min": 106.6336774994254, "p90": 106.66606919223108, "p95": 106.68423807647056, "p99": 106.69877318386216, "stddev": 0.01930653530818627 }, "values": [ 106.70240696071005, 106.66203166240008, 106.64410802226159, 106.65831409449595, 106.64148106986977, 106.6482935780762, 106.63974821679058, 106.65896986001393, 106.6336774994254, 106.65309236714002 ] }, "read_gb_s": { "statistics": { "average": 115.83111228356601, "max": 116.11098114619033, "median": 115.84480882265643, "min": 115.56959026587722, "p90": 115.99667266786554, "p95": 116.05382690702793, "p99": 116.09955029835784, "stddev": 0.1768243167963439 }, "values": [ 115.79154681380165, 115.56959026587722, 115.60574235736468, 115.72112860271632, 115.72147129262802, 115.89807083151123, 115.95527337086908, 115.95334642887214, 115.98397172582945, 116.11098114619033 ] }, "write_gb_s": { "statistics": { "average": 65.55966046805113, "max": 65.59040040480241, "median": 65.55933583741347, "min": 65.50911885624045, "p90": 65.5840272860955, "p95": 65.58721384544896, "p99": 65.58976309293172, "stddev": 0.02388146120866979 },Patterns benchmark also shows bit more of memory speeds. command: 'memory_benchmark -patterns -non-cacheable -count 5 -output patterns.JSON'Example M4 from 100 loops: "sequential_forward": { "bandwidth": { "read_gb_s": { "statistics": { "average": 116.38363691482549, "max": 116.61212708384109, "median": 116.41264548721367, "min": 115.449510036971, "p90": 116.54143114134801, "p95": 116.57314206456576, "p99": 116.60095068065866, "stddev": 0.17026641589059727 } } } }"strided_4096": { "bandwidth": { "read_gb_s": { "statistics": { "average": 26.460392735220456, "max": 27.7722419653915, "median": 26.457051473208285, "min": 25.519925729459107, "p90": 27.105171215736604, "p95": 27.190715938337473, "p99": 27.360449534513144, "stddev": 0.4730857335572576 } } } }"random": { "bandwidth": { "read_gb_s": { "statistics": { "average": 26.71367836895143, "max": 26.966820487564327, "median": 26.69907406197067, "min": 26.49374804466308, "p90": 26.845236287807374, "p95": 26.882004355057887, "p99": 26.95742242818151, "stddev": 0.09600564296001704 } } } }Thank you for reading :)
