May I suggest:

  #include <stdlib.h>   // card > aek.ppm
  #include <stdio.h>
  #include <math.h>
  typedef int i;typedef float f;struct v{
  f x,y,z;v operator+(v r){return v(x+r.x
  ,y+r.y,z+r.z);}v operator*(f r){return
  v(x*r,y*r,z*r);}f operator%(v r){return
  x*r.x+y*r.y+z*r.z;}v(){}v operator^(v r
  ){return v(y*r.z-z*r.y,z*r.x-x*r.z,x*r.
  y-y*r.x);}v(f a,f b,f c){x=a;y=b;z=c;}v
  this));}};i G[]={247570,280596,280600,
  249748,18578,18577,231184,16,16};f R(){
  return(f)rand()/RAND_MAX;}i T(v o,v d,f
  &t,v&n){t=1e9;i m=0;f p=-o.z/d.z;if(.01

I would say I've only used about 1% of the business cards that I've ever had.

In many settings where a business card is "typically" required, I've found that people are open to just sending a blank email (or maybe a few words of context) to the other person as a dual reminder to follow up later.

It might be worth it to buy some business cards to have on hand, but I wouldn't go overboard with quantity!


I still consider not making so many cards.

thanks for your answer.



Your name
A title/description
Email address / phone number / web site
A QR code, for 99% of people who will ask to scan it, then give the card back :)


I like the idea of ​​QR, I will apply it, thanks


I used to but found that not many people actually needed it.

The main things you should have on it are:

  • Email
  • Phone Number
  • Current Job Role
  • Key Skills(Max 3)

The point in a business card is really just so someone can contact you if needed, but it can be useful if you have space to add in the last 2.


I was considering these points. I also don't want to fill in unnecessary data.

The Art of Programming

One of the most consolidated misconceptions about programming, since the early days, is the idea that such activity is purely technical, completely exact in nature, like Math and Physics. Computation is exact, but programming is not.
