gruber / Liberal Regex Pattern for Web URLs
Last active April 22, 2024 19:02
Liberal, Accurate Regex Pattern for Matching Web URLs
The regex patterns in this gist are intended only to match web URLs -- http,
https, and naked domains like "example.com". For a pattern that attempts to
match all URLs, regardless of protocol, see: https://gist.github.com/gruber/249502
# Single-line version:

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style

Latency numbers every programmer should know

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

How to add a certificate from buffer in OpenSSL
X509 *cert;
char *zCert;
BIO *mem;
zCert = // get your certificate text buffer here (C string with certificate in PEM format)
mem = BIO_new(BIO_s_mem());
BIO_puts(mem, zCert);
cert = PEM_read_bio_X509(mem, NULL, 0, NULL);
free(zCert);
BIO_free(mem);
