The latest Toolcore batch adds another hundred browser-local pages in non-parametric statistics and physics formulas, Hill cipher and text puzzles, HMAC and checksum demos, punycode and uuencode, DNS SOA and CORS header parsers, Excel serial dates, and ISBN/ISIN check digits. Use this map when you know the job—not when you want to scroll the full catalog.
Non-parametric stats, time series, and physics-lite
- Mann-Whitney U, Wilcoxon signed-rank, and Kendall tau — rank-based tests from two pasted lists.
- Simple moving average, exponential smoothing, and lag-1 autocorrelation — lightweight time-series drills.
- Kinetic energy, Ohm law, and projectile motion — intro physics homework without a spreadsheet.
Ciphers, pangrams, and text layout
- Hill cipher 2×2, rail-fence encode, and Beaufort decode — classical cipher practice.
- Pangram check, isogram check, and Scrabble score — word-game and readability adjacent checks.
HMAC demos, checksums, punycode
- HMAC-MD5 demo, HMAC-SHA384 demo, and password entropy bits — digest shape and strength estimates locally.
- Punycode encode, Ascii85 encode, and hex dump with offset — encoding helpers beside the Encoding hub.
HTTP headers, Excel dates, identifiers
- DNS SOA parse, CORS header parse, and X-Forwarded-For parse — paste headers from curl or browser devtools.
- Excel serial to ISO, reverse Julian day, and moon phase (approx) — calendar conversions without Excel installed.
- ISBN-10 check digit, ISIN check digit, and ASIN format check — format and checksum only; no live directory lookup.
