Principles

• Infer the user's intent and task scope from instructions and prior conversation context.
• Choose the simplest implementation that fully solves the problem. Do not reimplement common functionality when a suitable library exists.
• Prefer deleting code over adding code. The best code is code that does not need to exist.
• Use established, maintained libraries when they reduce complexity or improve reliability.
• Write self-explanatory code. Add comments only when the code cannot express the necessary context.
• Before assuming a library lacks a capability, check its documentation, types, and source.
• Build features end to end in small increments. Do not design for hypothetical future requirements.
• Preserve backward compatibility only when required. Otherwise remove obsolete code instead of adding compatibility layers.

let regex;

/* matching a specific string */
regex = /hello/; // looks for the string between the forward slashes (case-sensitive)... matches "hello", "hello123", "123hello123", "123hello"; doesn't match for "hell0", "Hello" 
regex = /hello/i; // looks for the string between the forward slashes (case-insensitive)... matches "hello", "HelLo", "123HelLO"
regex = /hello/g; // looks for multiple occurrences of string between the forward slashes...

/* wildcards */
regex = /h.llo/; // the "." matches any one character other than a new line character... matches "hello", "hallo" but not "h\nllo"
regex = /h.*llo/; // the "*" matches any character(s) zero or more times... matches "hello", "heeeeeello", "hllo", "hwarwareallo"

Debug zsh startup time

1. Inject profiling code

   At the beginning of your .zshrc add following: zmodload zsh/zprof

   and at the end add: zprof

   This will load zprof mod and display what your shell was doing durung your initialization.

# Generate a new pgp key: (better to use gpg2 instead of gpg in all below commands)
gpg --gen-key
# maybe you need some random work in your OS to generate a key. so run this command: `find ./* /home/username -type d | xargs grep some_random_string > /dev/null`

# check current keys:
gpg --list-secret-keys --keyid-format LONG

# See your gpg public key:
gpg --armor --export YOUR_KEY_ID
# YOUR_KEY_ID is the hash in front of `sec` in previous command. (for example sec 4096R/234FAA343232333 => key id is: 234FAA343232333)

How to force a file download in the browser?

The use case is simple, you have /reports/593874951.pdf on your web server and want to let your user download it — and if possible with a meaningful name.

In the past, you may tried using the Content-Disposition HTTP header to achieve this, but today, with Safari getting the support for the download attribute it’s going to simplify a lot of things.

Using the download attribute is simple as pie:

<a href="/reports/593874951.pdf" download="report.pdf">
 Download report

Email address syntax validation? Let the browser do it (without regexp)

Here is a simple and robust way to check for the validity of an email address syntax directly in the browser. No need for crazy regular expressions.

e = document.createElement('input')
e.type = 'email'
// check some email addresses
e.value = 'hi@'
