Data Processing

Paste a JSON payload from any sports API (ESPN, TheSportsDB, balldontlie, football-data.org, api-sports.io) and get it rendered as a clean scoreboard with winners highlighted and game statuses.

Health

Compute SV = CO × 1000 / HR (mL/beat). Normal 60–100 mL; low in shock, hypovolemia, tachycardia; high in bradycardia and AR. Derived from Guyton & Hall, StatPearls, LITFL, Braunwald. Not medical advice.

Design

Upload one image and preview how it appears on Instagram Feed/Story/Reels, TikTok, YouTube, X, and LinkedIn — with platform safe-zone overlays showing exactly which pixels get cropped or covered by UI before you publish.

Health

Calculate the total body sodium deficit and safe correction rate to prevent ODS. Na⁺ deficit = TBW × (Target − Measured). Default 8 mmol/L/24h for chronic; 12 mmol/L/24h for acute symptomatic. 3% NaCl volume estimated. Derived from Adrogué NEJM 2000, Verbalis 2013, Spasovski 2014, Sterns 2018, and MDCalc. Not medical advice.

Development

Translate SQL between MySQL, PostgreSQL, SQLite, BigQuery, Snowflake, and Redshift — DDL, DML, functions and types, with UNSUPPORTED warnings

Development

Decode 64-bit Snowflake-style IDs for Discord, Twitter, Mastodon, Sonyflake, Instagram, or a custom bit profile. Extract timestamp, worker/process/machine, sequence fields, align platform epochs, and infer a Discord shard when a shard count is supplied.

Text Processing

Extract clean dialogue text from pasted SRT, ASS, or SSA subtitles.

Health

Estimate the average steady-state plasma concentration under repeated fixed-interval dosing: Css,avg = (F · Dose) / (CL · τ), where F is bioavailability (1 for IV, <1 for oral), CL is clearance, and τ is the dosing interval. If t½ and Vd are also provided, computes the one-compartment IV-bolus accumulation index Rac = 1/(1-e^(-kτ)), peak Cmax,ss, trough Cmin,ss, and time to ~94%/~97% of steady state (4/5 half-lives). Valid only for linear pharmacokinetics with fixed dose and interval — NOT for Michaelis-Menten drugs or non-linear kinetics. Not medical advice.

Math & Numbers

Convert sound power between linear units (W, mW, µW, pW) and the decibel sound power level dB Lw (Lw = 10·log₁₀(W / 1 pW), reference P₀ = 1 pW = 1e-12 W, per ISO 3744 / IEC 60027-3). Supports bidirectional linear↔logarithmic conversion and reports the equivalent value in all five units. Reference values: whisper ≈ 1e-9 W (Lw ≈ 30), speech ≈ 1e-5 W (Lw ≈ 70), jet engine at 1 m ≈ 1e4 W (Lw ≈ 160).

Math & Numbers

Convert sound pressure between linear units (Pa, µPa, µbar, mbar) and the decibel sound pressure level dB SPL (Lp = 20·log₁₀(p / 20 µPa), reference p₀ = 20 µPa = 2e-5 Pa RMS, per ISO 1683). Supports bidirectional linear↔logarithmic conversion. Calibration anchor: 1 Pa → 20·log₁₀(1/2e-5) ≈ 94 dB SPL. Reference values: threshold of hearing 20 µPa (0 dB), speech ≈ 0.02 Pa (60 dB), rock concert ≈ 20 Pa (120 dB), pain threshold ≈ 200 Pa (140 dB).

Math & Numbers

Convert specific heat capacity between J/(kg·K) (joule per kilogram-kelvin, SI base, = J/(kg·°C)), kcal/(kg·°C) (1 = 4186.8 J/(kg·K)), and BTU/(lb·°F) (1 = 4186.8 J/(kg·K)). Key identity: 1 kcal/(kg·°C) = 1 BTU/(lb·°F) — numerically equal because the energy/mass·temperature factors cancel. Converts via J/(kg·K) and lists all three equivalents. Reference values: water ≈ 4186, air cp ≈ 1005, aluminum ≈ 900, iron ≈ 450 J/(kg·K).

Math & Numbers

Specific strength = σ/ρ and specific modulus = E/ρ (optional E). Enter strength in MPa and density in g/cm³; output in N·m/kg (also as kN·m/kg). The figure of merit for lightweight design — a material with high strength but high density (e.g. tungsten) often loses to a lighter alloy. Typical values: Ti-6Al-4V ≈ 210 kN·m/kg, Al 7075 ≈ 180, carbon steel ≈ 50–90, CFRP ≈ 1000+.
