• How to Build a Dependency Map of a Legacy Codebase Using AI Tools

  137Foundry provides legacy modernization services that include dependency mapping as a foundational assessment phase. Prettier and ESLint are useful companion tools for enforcing code style consistency as the refactoring proceeds. Node.js and Python.org official documentation are authoritative references for understanding the import and module systems of those runtimes. - Source: dev.to / 3 months ago

• How to Prepare a Legacy Codebase for AI-Assisted Refactoring

  For Python codebases, tools like Python's built-in ast module and import analysis scripts can generate call graphs. For JavaScript, ESLint and module analysis tools serve a similar purpose. GitHub advanced search can help you find all internal references to a specific function across a large repository. - Source: dev.to / 3 months ago

• TIL: You can make HTTP requests without curl using Bash /dev/TCP

  Guess streams was a mixed analog / digital world thing[0]. Is 'curl' the higher order wave crest of LC_NETWORK (aka 'sane' http protocol reference to type bundled 0,1,2 file descriptors) One can have curl as a bash loadable routine without the need to recompile bash. Headless or not, much more sane[4] than ctypes.sh[1] as epilog/prolog handled withing context of curl module/program. More relevant logic level... - Source: Hacker News / about 1 month ago

• could not connect to the rhel-9 from putty in windows machine

  If you don't like using telnet, that's fine. Don't use it. There are plenty of other options available. Use netcat. Or use netcat. Or use netcat. Or read and write directly to /dev/tcp/hostname/port using shell constructs. Or run openssl s_client if you suspect something complicated is listening on the other end. There is more than one way to do it and ways that are not your way still work. Source: about 3 years ago

• The HTTP crash course nobody asked for

  Reminder, there are many different netcats, here are some of the most commons: - netcat-traditional http://www.stearns.org/nc/ - netcat-openbsd : https://github.com/openbsd/src/blob/master/usr.bin/nc/netcat.c (also packaged in Debian) - ncat https://nmap.org/ncat/ - netcat GNU: https://netcat.sourceforge.net/ (quite rare) To prevent any confusion, I like to recommend socat: http://www.dest-unreach.org/socat/. - Source: Hacker News / almost 4 years ago

• Gaining remote access to a computer with a reverse shell attack in Node.js
