This shell script shows how to update an IPFS DNSLink record through the Cloudflare API. It retrieves the zone ID for a specified domain, finds the existing `_dnslink` TXT record, and updates its content to point to a new IPFS hash. The script uses `curl` for HTTP requests, `jq` for parsing JSON responses, and relies on environment variables like `PAGES_CLOUDFLARE_EMAIL`, `PAGES_CLOUDFLARE_API_KEY`, `PAGES_DOMAIN_NAME`, and `PAGES_IPFS_RECORD` for configuration. It outputs progress messages and confirms the updated webpage URL.

Crontab-ready Python script to update AutoDNS / InternetX domains

This example shows a crontab-ready Python script that automatically updates a domain’s IP address with the AutoDNS/InternetX gateway. It retrieves the current public IP from `http://whatismyip.akamai.com/`, compares it to the stored last IP, and exits if unchanged. Using the `requests` library for HTTP calls and `click` for CLI options, it constructs and sends XML requests via the `xml.dom.minidom` module to fetch the zone state and apply the new IP. Logging via the `logging` module tracks progress and errors.

How to serve a custom HTTPS domain on GitHub Pages with CloudFlare: *FREE*, secure and performant by default

This example shows a step-by-step guide for serving a custom HTTPS domain on GitHub Pages through CloudFlare, emphasizing free, secure, and performant hosting. It demonstrates DNS configuration, nameserver setup, and Page Rules for forced HTTPS redirects, alongside GitHub repository setup with a CNAME file. The instructions reference GitHub Pages, CloudFlare’s SSL settings, and registrar DNS tools, presenting a clear workflow for static site deployment without code dependencies.

This example demonstrates a web interface for managing decentralized file storage on Filecoin, showing how users interact with a bridge API to store, deposit, release, and check the status of files. The code uses React hooks like `useState` and calls to a custom `api` object with methods such as `.store()`, `.addDeposit()`, `.releaseDeposit()`, and `.status()`, which handle file uploads, bridge deposits, fund releases, and deal status queries. Uploads are tracked in a state array, and responses include IPFS CIDs, while alerts and console warnings report errors or confirm actions. The visualization relies on the API's JSON responses rather than a rendering library.

Chain of Trust - but verify...

This visualization demonstrates the complete chain of trust in DNSSEC verification. Starting from a user-specified domain and TXT record flag, it systematically queries DNS records — including DNSKEY, DS, and RRSIG signatures — at every level of the DNS hierarchy from the target domain back to the root. Using the `dnspython` library and Cloudflare’s 1.1.1.1 resolver, the notebook collects signed TXT records, DNSKEYs, DS records, and their corresponding RRSIGs for each domain in the chain, storing the results as JSON. The visualization then walks this chain of trust, showing how cryptographic signatures tie each level to its parent, enabling the reader to verify the authenticity of the initial TXT record all the way back to the ICANN root.

This visualization tests the availability and response times of 19 public IPFS gateways by repeatedly pinning random-content files to a local peer and requesting them through each gateway. It measures either the HTTP status code or elapsed request time (in seconds) for every attempt, with timeouts recorded as 9999 and non-200 responses stored as their status code. The code uses the `ipfsapi` Python library to add files to a local IPFS node and the `requests` library to perform timed HTTP GET requests against each gateway URL. Results are printed as tuples of gateway name, time/status, and the content hash, revealing which gateways are fastest, slowest, or failing entirely.

This example demonstrates a shell script that sets up a cloud-based development environment, installing code-server and configuring it with nginx as a reverse proxy. It shows the infrastructure provisioning process, including user creation, SSH key copying, and self-signed SSL certificate generation using openssl. The code uses bash commands, systemd services, and nginx configuration to enable remote access to a VS Code instance through a secure HTTPS connection, with a redirect server for the --link feature. The script relies on curl, apt, and standard Unix utilities rather than visualization libraries.

Script useful to resize or extend a disk on EC2

This example presents a shell script that automates disk resizing operations for Amazon EC2 instances. It shows the sequential process of first checking current disk space with `df -h`, then applying the `resize2fs` command with a user-specified partition name, and finally verifying the resize was successful. The script documents each step through inline comments, making it a practical reference for system administrators. The visualization highlights the clear workflow of examination, action, and validation through command-line tools on a Linux filesystem.

This example shows a Bash script that installs Firejail and appends a set of filesystem blacklists to the `/etc/firejail/disable-common.local` configuration file. The code uses `apt-get` to update and install the `firejail` package, then checks if the local blacklist file exists before writing entries that deny access to sensitive paths such as `/etc/passwd`, `/etc/nginx`, and `/var/lib/mysql`. The script relies on shell redirection and a here-document to create the configuration content, with no visualization libraries or data sources involved.
