Calculate heating time for different microwave wattages
A tool to edit gzip-compressed text files in your browser. Upload a file, edit it, and save it back as gzip format. For example, this is useful when you want to easily check gzip-compressed text files on Windows.
Free online counter tool that lets multiple people count together in real-time by sharing a URL. Perfect for event attendance tracking, inventory management, headcounts, and survey tallying. No registration required.
Free tool to visualize CIDR and IP address ranges (IPv4 / IPv6) on a number line and calculate subnet details: network address, broadcast address, address range, usable host range, subnet mask, IPv4 class, and IPv6 address type. Supports CIDR splitting and merging, overlap checking, Terraform / CDK bulk text input, and URL sharing.
Edit a Reliability Block Diagram (RBD) directly and instantly compute system availability, annual/monthly downtime, and a verifiable formula. Supports arbitrary series/parallel nesting, k-out-of-n redundancy, and two input modes (Availability A, MTBF+MTTR). URL sharing, image export and auto-save included.
Calculate transfer time from data size, link bandwidth and effective throughput. Solve in three directions — time, required bandwidth, transferable size — with GB/GiB, bit/Byte and theoretical/effective differences made explicit. Compare up to 10 conditions with proportional bars, share by URL, autosave locally.
