>>43292725
Hey guys, can you help me? I'm trying to create a table on CSS for a HTTP web page. I'm really new at web coding and it's for a stupid project that I need to deliver in less then 3 hours haha.

>>43293825
<table></table> ?

on css? what

>>43293825
You don't create tables in CSS, you create them in HTML and apply visual styling with CSS. I would suggest a lot more reading, friend.

>>43293849
Yeah, like a class on CSS that I can call multiple times to put pictures on a web page, like 3 colums of 3, you know? I tried what you said and might word too.

>>43293872
I know man, but I really don't have the time right now, I'm on this shitty web developer curse and I really don't want to delay the project. I'm going to find a better one asap though.

>>43293894
Again, CSS is for styling. You can define a CSS class that will format the look of a table the same way every time, but not one that will just make the table appear there out of thin air.

A CSS class, btw:

.someclass {
text-color: black;
width: 50%; //etc....
}

Once a table is created, you would assign it the class you created by doing this:

<table class="someclass">
//table data goes here
</table>

>>43292725

I don't know what the fuck that is but I'll give it a shot.

>>43293939
Thanks for taking the time man, you helped me a lot.

>>43293996
Glad I could help.

>>43293980
User puts details into form, before it's processed and stored in the database numbers have to be the right length, emails the right format, dates converted to utc, things like that

>>43294042
What a coincidence, one of my semester projects for WebDev (which ends this week) was implementing Hibernate to validate data entered into a form on a JSP page.

It was a traumatizing experience.

Same here, but I was up til 3 studying for my Info Retrieval (read: SQL databases) final today, and I've already realized I'm not gonna get any work done today. Might as well do something fun.

Works with OpenBSD. GNU's date utility is different.

#!/bin/sh

now="$(date +"%s")"

printf "enter your birth date in the format YYYYMMDD: "

read then

then="$(date -j +"%s" "$then"0000)"

printf "you are %d seconds old\n" "$((now - then))"

I just did the ninth Project Euler problem in Matlab:

while sum(V) ~= 1000
    V(1:2) = randi(1000,1,2);
    V(3) = sqrt(V(1)^2+V(2)^2);

Answer = prod(V);

Could every one of these tasks be done in Scheme?

>>43301524
Scheme is Turing complete. So yes.

>>43301524
It would be extremely painful

Those tasks aren't done in order of difficulty are they?

Rallin

rolling for when I get home

Am I missing something about 28? Or is it just a freebie?

>>43302089
They aren't done in order of difficulty. However I think that the result is bigger than any primitives can hold (other that floating point, which wouldn't give the exact result).

>>43293968
That's the point, that's why you're rolling to see which one you can do, there are a wide variety of problems. A lot of textbooks mix stupidly easy problems with insanely difficult ones. The Art of Computer Programming assigns unsolved problems.

In what language would it have an average difficulty?

>>43302345
ASM

>>43302355
Got it, thanks.

>>43302453

never used rss in my life rerolling

Working on an algorithm that, given triangular matrix of circles (all the same radius and separated so they don't touch and whose midpoints are set so that they form an equilateral triangle) and a point, will check if the point is contained within one of the circles. The algorithm I currently have in mind starts at a corner and checks the distance from the point to the midpoint of that circle. Then given that distance we know which other circles could possibly contain the point

Are these threads daily or I was lucky to stumble upon one?

>>43292725

Rollin.

I'm working on making a PHP email form. Mostly use Python, need to learn PHP for work though. Any help on this?

#!/usr/bin/env python3.4

vowels = ['a', 'e', 'i', 'o', 'u']

def vowelcount():
string = input("Input: ").lower()
count = 0
for i in string:
if i in vowels:
count += 1
print(count)

vowelcount()
</code>
Is this good? Or could I do something better? I haven't been doing python for that long so any feed back would be appreciated.

>>43303976
Hopefully this formats it correctly...

How the fuck to I generate ASCII graphics anyway?

I was just thinking earlier, how do people make, let's say, a grid in a terminal and plot points on it? Or graph a sine wave just through text? I saw a C program that did that with some weird printf trick that I don't understand.

Top jej.
Now make it enclose the quote in quotation marks.

>>43304366
change the 'for i in range(10): print (generate_quote())' part of your code to this -

stop = 'Go'
while stop != 'stop':
    for i in range(10):
        print(generate_quote())
    stop = raw_input('Type \'stop\' to stop.)

and it would be shippable as a professional application. :^)
