What it does
My mission is to promote HTTPS encryption across the internet. Providing a free monitoring tool helps ensure that everyone can maintain secure websites without barriers and make sure your SSL will not expire.
Control up to 100 SSL certificate and domain expiration - for free! Find A, AAAA, CNAME, MX, NS, TXT, SOA DNS records of a host. Extract all the text of a website from the source code of the page. Check the total size of a web page, including all resources, for performance analysis. Get all the HTTP headers that an URL returns for a typical GET request. Check whether a website is using the new HTTP/2 protocol or not. Check for 301 & 302 redirects of a specific URL. It will check for up to 10 redirects. Take an IP and try to look for the domain/host associated with it. Check whether a website is using the Brotli Compression algorithm or not. Track your SSL and domain expiration monitoring.…from sslstate.com

Hi everyone, I built PyXL — a hardware processor that executes a custom assembly generated from Python programs, without using a traditional interpreter or virtual machine. It compiles Python -> CPython Bytecode -> Instruction set designed for direct hardware execution. I’m sharing an early benchmark: a GPIO test where PyXL achieves a 480ns round-trip toggle — compared to 14-25 micro seconds on a MicroPython Pyboard - even though PyXL runs at a lower clock (100MHz vs. 168MHz). The design is stack-based, fully pipelined, and preserves Python's dynamic typing without static type restrictions.…
