To generate native assembly code (x86-64 asm, ARM64, etc.) from OCaml’s native compiler, use the -S flag along with other optimization-related options: ocamlopt -S -inline 20 -nodynlink not.ml -o not.opt This produces a .s file containing the generated assembly. The flags break down as: -S — Stop after assembly generation and keep the .s file…
Linux routing tables exist in kernel memory during runtime. To persist routes across reboots, you need to store them on disk and have them reloaded during system startup. The mechanism varies depending on your network management setup. systemd-networkd and netplan (modern systems) On contemporary distributions using systemd-networkd or netplan, define routes in YAML configuration files….
When you pipe a plain text file to mailx, it analyzes the content to determine the MIME type. If it detects non-standard characters (anything other than newlines and horizontal tabs), it defaults to application/octet-stream and base64-encodes the message. Most email clients then treat this as an attachment rather than inline content. This is the problematic…
A MySQL table marked as crashed typically occurs after unclean shutdowns, power failures, or server crashes. Error 145 indicates the table structure is corrupted and needs repair before queries can proceed. Checking Table Status Before attempting repair, check the table status: CHECK TABLE mybb_sessions; This returns detailed information about corruption. Common status values: OK —…
Local branches List all branches on your local repository: git branch This shows only branches that exist locally on your machine. Remote branches To list all branches on the remote server, use the -r flag: git branch -r This displays remote-tracking branches — local references to branches that exist on the remote repository. These are…
You can run OCaml scripts directly from the command line with a shebang, similar to bash or Python. This requires making the file executable and using the proper interpreter directive. Basic Script Setup Create a file with a .ml extension and add a shebang at the top: #!/usr/bin/env ocaml print_endline “Hello world!”;; Then make it…
