At Georgia Tech, I took a course called "Media Device and Architecture" in which we learned how to program in low-level C by creating GameBoy games and get a taste of what assembly level programming was like. Through our assignments, we learned how to connect hardware and software worked together by using C code to manipulate device hardware. We were also introduced to basic game programming methods and game design techniques. We learned how to use the program Usenti to turn sprite images into bitmaps that could then be used in GameBoy games by indexing the pixels in the images.
For our final project, we were tasked with creating a GameBoy game in C using what we had learned in class. There were no limitiations as to what kind of gameplay was necessary or how the game looked, but it had to have the following components in the game:
I brainstormed many ideas, but at the end I decided to go with a basic game that centered around a boy who had to clean up his house before his mom arrived home.
You move around with arrow keys to pick up trash around the house. If you accidentally collide with a vase, you have to return it to the nearest shelf before you can collect any other trash so you don't accidentally break it. If you run into a dog, the timer decreases by 5 seconds.
Collect all the trash before the timer runs out (60 seconds) and mom comes home.

If a player collides into a piece of trash, it "picks" it up. Colliding into a vase forces you to collide with a shelf to place it on the shelf. Character turns red if it's currently holding a vase.
I also sketched a few priliminary sketches to get a better visualize how the game layout would appear in real life.
For my "cheat" state, I ended up adding two controls in which when you Press A to move fast in a run and Press L while moving to run through vases and dogs without any repercussions.When the L is pressed, the character is surrounded by a yellow flame to indicate they are invinsible.
I drew all the graphics, screens, and sprites using Usenti's paint feature and I created a sprite sheet bitmap. In addition, to make collisions for the furniture and walls on the map to prevent the player from being able to walk through them, I created a collision map in Usenti as well. State machines were also important to the basis of my game code because it made it easy to transition from screen to screen. It was more organized in the code and most efficient to implement.
For the look of the game, I went with a simple 8-bit appearance to mimic the old school, retro appearance that many games of the GameBoy time had.
The following video is an example of the game play and the final version that I submitted for class. The first playthrough shows a scenario in which the player loses. They run into dogs, lose time, and are forced to waste more time returning vases. The second playthrough shows the player using the running and invincible cheats to win the game.
You can take a closer look at the code and art right here
Taking this class gave me my first exposure to how hardware and software connected together. In addition, although it was not the intention of the course, game design and programming were what I felt I gained the most from the course itself. Working on this GameBoy project gave me a glimpse into the effort it takes into making games, and I truly respect the effort game makers put into their products.
If I could do this again, I would make the graphics much more detailed and give them dimension. I was unfamiliar with drawing in 8-bit, pixel art because it was my first time working with Usenti. The text when drawn in with Usenti was difficult to read because it was so pixelated and blocky, and the art did not have the detail that I wanted. I was more focused on programming the backend of the project that I dedicated less time to the graphics. Next time, I would like to play around with using Photoshop to create more detailed graphics and import them into Usenti to create a more aesthetically pleasing experience.

Overview
Waiters
are utility methods that poll for a particular state to occur
on a client. Waiters
can fail after a number of attempts at a polling
interval defined for the service client.
For a list of operations that can be waited for and the
client methods called for each operation, see the table below or the
Client#wait_until field documentation for the Client
.
Invoking a Waiter
To invoke a waiter, call #wait_until on a Client
. The first parameter
is the waiter name, which is specific to the service client and indicates
which operation is being waited for. The second parameter is a hash of
parameters that are passed to the client method called by the waiter,
which varies according to the waiter name.
Wait Failures
To catch errors in a waiter, use WaiterFailed, as shown in the following example.
rescue rescue Aws::Waiters::Errors::WaiterFailed => error
puts "failed waiting for instance running: #{error.message}
end
Configuring a Waiter
Each waiter has a default polling interval and a maximum number of
attempts it will make before returning control to your program.
To set these values, use the max_attempts
and delay
parameters
in your #wait_until
call.
The following example waits for up to 25 seconds, polling every five seconds.
client.wait_until(...) do |w|
w.max_attempts = 5
w.delay = 5
end
To disable wait failures, set the value of either of these parameters
to nil
.
Extending a Waiter
To modify the behavior of waiters, you can register callbacks that are triggered before each polling attempt and before waiting.
The following example implements an exponential backoff in a waiter by doubling the amount of time to wait on every attempt.
client.wait_until(...) do |w|
w.interval = 0 # disable normal sleep
w.before_wait do |n, resp|
sleep(n ** 2)
end
end
Available Waiters
The following table lists the valid waiter names, the operations they call,
and the default :delay
and :max_attempts
values.

Uses rotate() to rotate a point around a relative center.
Rotates a point around the x, y, and z axes concurrently.
For an example of how it rotates the x and y axes at the same time.
It will first rotate so that the slanted rotation will be around the x axis.
Then it will rotate the same amount of distance as if it were moving slanted.
Last it will rotate back to make the rotation slanted.
Rotates a point around an axis using degrees. This is slower than using ucRot().
Rotates a point around an axis using unit circle coordinates.
Known lengths within similar triangles are used to find the vertical value of the rotated point.
The horizontal value is found the same way.

===============================================================================
If you want the numerical value of a string, this will return a float or int
value:
Example:
===============================================================================
Note that the function accepts extremely big numbers and correctly evaluates
them.
For example:
The above script will output:
bool(true)
So this function is not intimidated by super-big numbers. I hope this helps
someone.
PS: Also note that if you write is_numeric (45thg), this will generate a parse
error (since the parameter is not enclosed between apostrophes or double
quotes). Keep this in mind when you use this function.
===============================================================================
The documentation is not completely precise here. is_numeric will also return
true if the number begins with a decimal point and/or a space, provided a
number follows (rather than a letter or punctuation). So, it doesn't
necessarily have to start with a digit.
===============================================================================
The documentation does not clarify what happens if you the input is an empty
string - it correctly returns false in my experience. Useful to state these
odd cases, for when you see code that checks for an empty string and
is_numeric, you can tell it's a waste of a comparison.
===============================================================================
When using the exec() function in php to execute anther php script, any command
line arguments passed the script will lose their type association, regardless
of whether they are numeric or not, the same seems to hold true for strings as
well.
ie : two scripts test.php:
and testwrapper.php:
Executing testwrapper.php on the command line will echo nothing (ie false), and
false will be returned regardless of any escaping of parameters or other such
attempts to overcome this. The solution then is to explicitly cast $val in
test.php to be an int and then is_numeric will work. But as stated the same
test was performed using a string for $val and the is_string() function and the
same thing occurs. Not the end of the world, but something to be aware of :)
===============================================================================
Here's an even simpler pair of functions for finding out if a number is odd or
even:
function IS_ODD($number) { return($number & 1); }
function IS_EVEN($number) { return(!($number & 1)); }
Test:
$myNumber = 151;
if(IS_ODD($myNumber))
echo("number is odd\n");
else
echo("number is NOT odd\n");
if(IS_even($myNumber))
echo("number is even\n");
else
echo("number is NOT even\n");
Results:
number is odd
number is NOT even
===============================================================================
is_numeric fails on the hex values greater than LONG_MAX, so having a large hex
value parsed through is_numeric would result in FALSE being returned even
though the value is a valid hex number
===============================================================================
Two simple functions using is_numeric:
";
//is_numeric(0) returns true
echo "0: odd? ".(is_odd(0)? "TRUE": "FALSE")."
";
echo "6: odd? ".(is_odd(6)? "TRUE": "FALSE")."
";
echo "\"italy\": odd? ".(is_odd("italy")? "TRUE": "FALSE")."
";
echo "null: odd? ".(is_odd(null)? "TRUE": "FALSE")."
";
echo "1: even? ".(is_even(1)? "TRUE": "FALSE")."
";
echo "0: even? ".(is_even(0)? "TRUE": "FALSE")."
";
echo "6: even? ".(is_even(6)? "TRUE": "FALSE")."
";
echo "\"italy\": even? ".(is_even("italy")? "TRUE": "FALSE")."
";
echo "null: even? ".(is_even(null)? "TRUE": "FALSE")."
";
?>
And here is the result:
1: odd? TRUE
0: odd? FALSE
6: odd? FALSE
"italy": odd? FALSE
null: odd? FALSE
1: even? FALSE
0: even? TRUE
6: even? TRUE
"italy": even? FALSE
null: even? FALSE
===============================================================================
Here's a function to determine if a variable represents a whole number:
function is_whole_number($var){
return (is_numeric($var)&&(intval($var)==floatval($var)));
}
just simple stuff...
is_whole_number(2.00000000001); will return false
is_whole_number(2.00000000000); will return true
===============================================================================
Sometimes, we need to have no letters in the number and is_numeric does not
quit the job.
You can try it this ways to make sure of the number format:
function new_is_unsigned_float($val) {
$val=str_replace(" ","",trim($val));
return eregi("^([0-9])+([\.|,]([0-9])*)?$",$val);
}
function new_is_unsigned_integer($val) {
$val=str_replace(" ","",trim($val));
return eregi("^([0-9])+$",$val);
}
function new_is_signed_float($val) {
$val=str_replace(" ","",trim($val));
return eregi("^-?([0-9])+([\.|,]([0-9])*)?$",$val);
}
function new_is_signed_integer($val) {
$val=str_replace(" ","",trim($val));
return eregi("^-?([0-9])+$",$val);
}
It returns 1 if okay and returns nothing "" if it's bad number formating.
===============================================================================
Referring to previous post "Be aware if you use is_numeric() or is_float()
after using set_locale(LC_ALL,'lang') or set_locale(LC_NUMERIC,'lang')":
This is totally wrong!
This was the example code:
-----
set_locale(LC_NUMERIC,'fr');
is_numeric(12.25); // Return False
is_numeric(12,25); // Return True
is_float(12.25); //Return False
is_float(12,25); //Return True
-----
This is nonsense!
- set_locale() does not exist, you must use setlocale() instead
- you have to enclose 12,25 with quotes; otherwise PHP will think that
the function gets _two_ arguments: 12 and 25 (depending on PHP version and
setup you may additionally get a PHP warning)
- if you don't enclose 12,25 with quotes the first argument will be the
inspected value (12), the second value (25) is discarded. And is_numeric(12)
and is_float(12) is always TRUE
Corrected Example:
----
setlocale(LC_NUMERIC,'fr');
is_numeric(12.25); // Return True
is_numeric("12,25"); // Return False
is_float(12.25); //Return True
is_float("12,25"); //Return False
----
Remarks:
- is_float(12.25) is _always_ TRUE, 12.25 is a PHP language construct (a
"value") and the way PHP interpretes files is definitely _not_ affected by the
locale
- is_float("12,25") is _always_ FALSE, since is_float (other than is_numeric):
if the argument is a string then is_float() always returns FALSE since it does
a strict check for floats
And the corrected example shows: you get the _same_ results for every possible
locale, is_numeric() does not depend on the locale.
===============================================================================
I needed a number_suffix function that takes numbers with thousand seperators
(using number_format() function). Note that this doesn't properly handle
decimals.
Example:
= number_suffix('1,021') ?> returns: 1,021st
Also, increasing the range above the condition statements increases
efficiency. That's almost 20% of the numbers between 0 and 100 that get to end
early.
function number_suffix($number)
{
// Validate and translate our input
if ( is_numeric($number) )
{
// Get the last two digits (only once)
$n = $number % 100;
} else {
// If the last two characters are numbers
if ( preg_match( '/[0-9]?[0-9]$/', $number, $matches ) )
{
// Return the last one or two digits
$n = array_pop($matches);
} else {
// Return the string, we can add a suffix to it
return $number;
}
}
// Skip the switch for as many numbers as possible.
if ( $n > 3 && $n < 21 )
return $number . 'th';
// Determine the suffix for numbers ending in 1, 2 or 3, otherwise add a
'th'
switch ( $n % 10 )
{
case '1': return $number . 'st';
case '2': return $number . 'nd';
case '3': return $number . 'rd';
default: return $number . 'th';
}
}
?>
===============================================================================
Hi !
Many of you may have experienced that the 'is_numeric' function seems to fail
always when form entries are checked against their variable type. So the
function seems to return 'false' even if the form entry was aparently a number
or numeric string.
The solution is pretty simple and no subroutines or fancy operations are
necessary to make the 'is_numeric' function usable for form entry checks:
Simply strip off all (invisible) characters that may be sent along with the
value when submitting a form entry.
Just use the 'trim' function before 'is_numeric'.
Example:
$variable = trim($variable);
if (is_numeric($variable)
{...#do something#...}
else
{...#do something else#...}
===============================================================================
===============================================================================
Note that this function is not appropriate to check if "is_numeric" for very
long strings. In fact, everything passed to this function is converted to long
and then to a double. Anything greater than approximately 1.8e308 is too large
for a double, so it becomes infinity, i.e. FALSE. What that means is that, for
each string with more than 308 characters, is_numeric() will return FALSE, even
if all chars are digits.
However, this behaviour is platform-specific.
http://www.php.net/manual/en/language.types.float.php
In such a case, it is suitable to use regular expressions:
function is_numeric_big($s=0) {
return preg_match('/^-?\d+$/', $s);
}
===============================================================================
A little function to ordinalize numbers using is_numeric() and accounting for
the numbers in the teens.
= 11 and $num <= 19)
return $num."th";
elseif ( $num % 10 == 1 )
return $num."st";
elseif ( $num % 10 == 2 )
return $num."nd";
elseif ( $num % 10 == 3 )
return $num."rd";
else
return $num."th";
}
// Demo
for ($i=1; $i<=25; $i++) {
print ordinalize($i) . " ";
}
// The loop returns:
// 1st 2nd 3rd 4th 5th 6th 7th 8th 9th 10th 11th 12th
// 13th 14th 15th 16th 17th 18th 19th 20th 21st 22nd
// 23rd 24th 25th
?>
===============================================================================
Function for checking all the values in an array for being numeric:
$value) {
if (!is_numeric($value)) return false;
}
return true;
}
$array_not_numeric = array('1', '2', 3, 'a'); // returns false
$array_numeric = array('1', '2', 3, 4); // returns true
?>
===============================================================================
empty(trim($test, '+-.,0123456789')) doesn't assure you $test contains a
number. It returns TRUE also for a string containing ".+1234.56", which is not
a valid number.
===============================================================================
To James holwell:
Maybe your function was more strickt, but profides FALSE to any numeric string
that wasnt written in the English/American notition. To enable a person to use
the both the English/American and the rest of the world's way:
Other than that, i'd recommend using yours, if it works (i havent tested either
yours or mine)
By using mine, there might be a slight chance to not being able to do
calculations with the numeric string if it's not the English/American way.
(*Note:
-the E/A way of writing 1 million (with decimal for 1/50): 1,000,000.02
-the global way of writing 1 million (with decimal for 1/50): 1.000.000,02
===============================================================================
Note that this function handles leading spaces differently than is_int(),
is_float(), is_real(), is_long(), and is_double().
is_numeric(" 12345") = true
is_int(" 12345") = false
is_float(" 12345") = false
is_real(" 12345") = false
is_long(" 12345") = false
is_double(" 12345") = false
===============================================================================
the best way to check whether
variable is numeric is to check its ascii code :)
function is_num($var)
{
for ($i=0;$i=49 && $asci_code <=57)
continue;
else
return false;
}
return true;
}
this function can be usefull if you wont to chec eg $_POST
function test_post($tab)
{
$post = array();
$post=$tab;
echo $tab["user_name"];
foreach ($post as $varname => $varvalue)
{
if (empty($varvalue))
{
$post[$varname] = null;
}elseif (is_num($varvalue))
{
$post[$varname]=trim($varvalue);
$post[$varname]=strip_tags($varvalue);
$post[$varname]=intval($varvalue);
$post[$varname]=addslashes($varvalue);
}else
{
$post[$varname]=NULL;
}
}
}//forech
return $post;
}
===============================================================================
I find it a little weird that people are having issues with ordinal numbers,
it's pretty easy..
Notes are in the commenting, check out the example outputs.
10&&$o%100<20)?0:($o%10<4?$o%10:0)]);
}
var_dump(ordinal(5));
/* Example Outputs of ordinal():
0th, 1st, 2nd, 3rd, 4th, ..., 9th,
10th, 11th, 12th, 13th, 14th, ..., 19th,
110th, 111th, ..., 199th, 200th, 201st.
ordinal('-1'); returns false because ctype_digit hates anything that
isn't strictly 0 through 9 and '-' trips it to false.
ordinal('asdf'); returns false for the exact same reason.
ordinal(); returns false because it's blank.
signed integers on a 32-bit system (and the same issue on a 64-bit
system using 0x7FFFFFFFFFFFFFFF because of two's compliment,
anything higher will become a negative number):
ordinal(0x7FFFFFFF ); returns<PHONE_NUMBER>th (which is correct)
ordinal(0x7FFFFFFF+1); returns false.

In reply to www.kigoobe.com, a more strict expression is
This will not match strings like -6,77.8,8 which are matched by the below
expression, and instead requires a single decimal point, with at least one
character following, and only permits comma-separation when the right hand side
is a triplet.
===============================================================================
if speed is important, the liberal use of regex should be avoided, especially
complex ones like those here.
For most purposes, this will be sufficient and has the advantages of both speed
and clarity.
$BoolResult = empty(trim($Test, '+-.,0123456789'));
If the $Test contains any character that is not a valid part of a number the
remaining string will not be empty.
if you want to be more restrictive of the '+-' then you can use a separate
trim for that and nest it. Keep in mind that some notations pt the sign to the
right of the number instead of to the left. Depending upon your specific
application you can also choose to ignore spaces and allow for 'e' notation.
I also use this approach when testing for other character sets such as Hex.
===============================================================================
Apparently NAN (Not A Number) is a number for the sake of is_numeric().
Outputs "is a number". So something that is NOT a number (by defintion) is a
number...
===============================================================================
There's no way to check if a string contains a float number so here's a tricky
one:
===============================================================================
Here is a simple function that I found usefull for filtering user input into
numbers.  For example:
$userString = "$654.4r5";
function numpass_filter($userString){
$money = explode(".", $userString);
//now $money[0] = "$645" and $money[1] = "4r5"
//next remove all characters save 0 though 9
//in both elements of the array
$dollars = eregi_replace("[^0-9]", null, $money[0]);
$cents = eregi_replace("[^0-9]", null, $money[1]);
//if there was a decimal in the original string, put it back
if((string)$cents!=null){
$cents = "." . $cents;
}
$result = $dollars . $cents;
return($result);
}
The output in this case would be '654.45'.
Please note that this function will work properly unless the user fat fingers
an extra decimal in the wrong place.
===============================================================================
Be careful when using `is_numeric()` to validate user input and protect against
SQL injection. According to wiki.hashphp.org,
"Many people reach for is_numeric() thinking this is a good approach, and it
will seem to work just fine. However the problem with is_numeric() isn't that
it can't detect an integer, it is that it detects a lot more than just
integers. All of the following are valid numbers to is_numeric():
- 1
- 1.123
- 0xFF
- +0123.45e6
See the problem? If we really want just an integer, this function is too
broad."
Source: http://wiki.hashphp.org/Validation#Why_is_numeric.28.29_is_bad
===============================================================================
If you want detect integer of float values, which presents as pure int or
float, and presents as string values, use this functions:
PHP_INT_MAX) {
return false;
}
return is_float($val) ? false : preg_match('~^((?:\+|-)?[0-9]+)$~', $val);
}
function isFloat($val)
{
if (!is_scalar($val)) {
return false;
}
return is_float($val + 0);
}
foreach ([
'11111111111111111',<PHONE_NUMBER>1111111, // > PHP_INT_MAX - presents in PHP
as float
1, '10', '+1', '1.1', 1.1, .2, 2., '.2', '2.',
'-2.', '-.2', null, [], true, false, 'string'
] as $value) {
echo $value . ':' . gettype($value) . ' is Integer? - ' . (isInteger(
$value) ? 'yes' : 'no') . PHP_EOL;
echo $value . ':' . gettype($value) . ' is Float? - ' . (isFloat($value) ?
'yes' : 'no') . PHP_EOL;
}
?>
Output:
11111111111111111:string is Integer? - no
11111111111111111:string is Float? - yes
1,1111111111111E+16:double is Integer? - no

Check that value is whole numeric or is whole integer.
Result will be like this:
===============================================================================
check if given string is mobile number
function filterNumber($str)
{
//remove non number
$count = strlen($str);
$newNumber = "";
for($i = 0; $i<$count; $i++)
{
if(is_numeric($str[$i]))
$newNumber .= $str[$i];
}
//removes leading 0s
$newNumber = ltrim($newNumber, '0');
//remove 91 in starting, 91 is specific to Indian Numbers
if(strlen($newNumber) == 12)
{
if(substr($newNumber, 0, 2) == '91')
$newNumber = substr($newNumber, 2);
}
//final check for length 10
if(strlen($newNumber) != 10 )
return null;
else

I think that is best check solution if u want to create real calculator for
example :)
= 0 && is_string($var) && !is_float($var)) {
return (bool) ctype_digit($var);
}
return (bool) is_numeric($var);
}
is_number(12); // true
is_number(-12); // true
is_number(-12.2); // true
is_number("12"); // true
is_number("-124.3"); // true
is_number(0.8); // true
is_number("0.8"); // true
is_number(0); // true
is_number("0"); // true
is_number(NULL); // false
is_number(true); // false
is_number(false); // false
is_number("324jdas32"); // false
is_number("123-"); // false
is_number(1e7); // true
is_number("1e7"); // true
is_number(0x155); // true
is_number("0x155"); // false

regarding the global vs. american numeral notations, it should be noted that at
least in japanese, numbers aren't grouped with an extra symbol every three
digits, but rather every four digits (for example 1,0000 instead of 10.000).
also nadim's regexen are slightly suboptimal at one point having an unescaped
'.' operator, and the whole thing could easily be combined into a single regex
(speed and all).
adjustments:
i'm sure this still isn't optimal, but it should also cover japanese-style
numerals and it fixed a couple of other issues with the other regexen. it also
allows for an exponent suffix, the pre-decimal digits are optional and it
enforces using either grouped or ungrouped integer parts. should be easier to
trim to your liking too.
===============================================================================
"$e = (int) substr( $n , -2 );"
What the heck am I thinking.
'st' , 2=>'nd' , 3=>'rd' );
$e = $n % 100;
$x = $n % 10;
return $n.( ( $x > 0 && $x < 4 && ( $e < 11 || $e > 13 ) ) ? $s[$x] : 'th'
);
}
?>
===============================================================================
Be careful when using is_numeric() to escape SQL strings. is_numeric('0123')
returns true but 0123 without quotes cannot be inserted into SQL. PHP
interprets 0123 without quotes as a literal octal number; but SQL just throws a
syntax error.
Casting a value to float then string and comparing it to the original value
cast as string as the same effect as is_numeric but returns false for numeric
strings that begin with zero and have no decimal point. Examples:
===============================================================================
Original Vlaue:".@$_GET['d'];
//then using clear value of $d in the mysql query
$sql = "select * from books where bookid = '$d' ";
?>
Example:
?d=52;d;s;s'2233l'[[22
Outpt:
Cleared value: 52223322
Original Vlaue:52;d;s;s'2233l'[[22
===============================================================================
Test if a number is positive and contains only 0-9:
function is_number($number)
{
$text = (string)$number;
$textlen = strlen($text);
if ($textlen==0) return 0;
for ($i=0;$i < $textlen;$i++)
{ $ch = ord($text{$i});
if (($ch<48) || ($ch>57)) return 0;
}
return 1;
}
returns
0 : number contain character outside 0-9
1 : valid number.
===============================================================================
This function converts an input string into bool, int or float depending on its
content.
'90' return an int
'90.9' return a float
'true' return a bool
'90.0' return a int
===============================================================================
Regarding renimar at yahoo's function to yield ordinal numbers, the function
lacks one thing. It accounts for numbers in the teens only if the number is
below 100. If you used this function and gave 212 as the input, it would give
212nd, and not 212th. (Also, checking for numbers between 11 and 13 is
sufficient, since 14-19 yield th either way.)
Therefore,
= 11 and $num <= 19) ?>
should be changed to...
= 11 and $num % 100 <= 13) ?>
It will then work perfectly all the time.
Here's the entire function with the one line changed:
= 11 and $num % 100 <= 13)
return $num."th";
elseif ( $num % 10 == 1 )
return $num."st";
elseif ( $num % 10 == 2 )
return $num."nd";
elseif ( $num % 10 == 3 )
return $num."rd";
else // $num % 10 == 0, 4-9
return $num."th";
}
?>
===============================================================================
I see a lot of examples below to get the ordinal string for a given number
("1st", "2nd", "3rd", "4th", etc). If you only need small ordinals (up to
"31st" at most), this one-line trick works:
===============================================================================
If I may, i think there is a simpler way to determine if a number is odd or
even:
if( $number & 1 ) //Just check the last bit!
echo 'It's odd!';
else
echo 'It's even!';
===============================================================================
Miero: Your function doesn't match some special cases: '+1', '-0', '+0', all of
which are valid integers. The easiest and most reliable way to get a definite
integer match is with a regular expression:
function is_intval($value) {
return 1 === preg_match('/^[+-]?[0-9]+$/', $value);
}
This has two "problems" based on your input: it matches both '00' and
'999999999999999999999999999999999' as valid integers.
I'm not sure why you wouldn't want to match "00". Regardless of whether
somebody entered it in a form by accident or on purpose, it /is/ a valid
integer, and in most instances you should accept it.
The second value, "999..." is also a valid integer, even if PHPs internal int
type isn't precise enough to represent it.
===============================================================================
in version 4.3.10 I find the following
".73" TRUE
"0.73" TRUE
"+0.73" TRUE
"+.73" FALSE
I would not call it a bug, just something to be aware of.
-----
Also be aware that if you give php a huge number and then you convert it to a
string you get
"INF"
if you pass that to mySQL etc. you could have a problem...

blazatek at wp dot pl wrote a function to check POST inputs for ASCII-keys or
smth like that. there was an error while filtering $varvalue (it was only the
value of the last filter 'addslashes')
here's the corrected function:
function is_num ($num) {
// .....
}
function test_post($tab) {
$post = array();
$post = $tab;
foreach ($post as $varname => $varvalue) {
echo $tab[$varname];
if (empty($varvalue)) {
$post[$varname] = null;
}
elseif (is_num($varvalue)) {
$varvalue=trim($varvalue);
$varvalue=strip_tags($varvalue);
$varvalue=intval($varvalue);
$post[$varname]=addslashes($varvalue);
}
else {
$post[$varname]=NULL;
}
}//forech
return $post;
}
?>
hope that correction is correct ;)
===============================================================================
I had troubles when using this as an is_hex function, if anyone else runs into
troubles here is an alternative approach. Not a very efficient one, but it
worked quite well for what i needed it for.

Be aware if you use is_numeric() or is_float() after using set_locale
(LC_ALL,'lang') or set_locale(LC_NUMERIC,'lang')
Example :
If at the beginning of your script, you declare :
and after, you will get this :
Because, for french language the decimal separator is ',' (Comma) instead of
'.' (Dot).

"Returning to Barca' We will see what happens..."
by BeSoccerDani Olmo left Barca to try his luck with Dinamo Zagreb. The player thinks he made the right decision. In an interview with 'Mundo Deportivo", he didn't rule out a possible Barcelona return.
"I don't close the door to any club, not to Barça either. We'll see what happens ... Now I am a Dinamo player and we will see what has to happen in the future...", Dani Olmo said.
The Spaniard would be delighted to play in La Liga one day. "I wish, why not be able to return?", he made clear.

He went over what he learned during his time at La Masia. "I keep the values. I also learned about style. At Barça there is a lot of touch play, mobile play... That's what I've learned the most", he underlined.
But for now, he is only thinking about his team. "I am focussed on Dinamo Zagreb. We have just started the season and I think it will be a very good one. We have started well in the Champions League, there are still 2 matches left and it is in our own hands to get through to the next round. There is still a lot of work to be done", he concluded.
Dani Olmo is attracting the attention of big clubs. Teams like Man City, Juventus and Milan are following the Dinamo Zagreb player closely. He prefers to leave his future aside and enjoy the moment.


USPS is recruiting elves to help spread Christmas cheer through 'Operation Santa'
by KNOE(CNN/Gray News) - This year, you can bring a little Christmas magic to a child in need with the United States Postal Service’s “Operation Santa.”
The program started in 1912, with local postal workers and everyday people responding to children’s letters to Santa. It evolved over the next 100 years into an initiative all its own.
Today, people can go to uspsoperationsanta.com to get involved.
An online form will ask potential participants to fill out a form and verify their identity.
Then they can browse letters online and “adopt” a child.
All over the country kids send letters to Santa, asking for everything from toys to basics, like a warm coat or shoes.
You can pick a letter from any city in the country, and USPS is adding letters to the site throughout the holiday season. They urge participants to check back as letters from new states are added and the list expands.
It’s also tax deductible.
The children are kept anonymous. Any personal information, last names, addresses and contact information is redacted.
Each letter has a code that links to the writer’s address. Postal workers use that code to find the address and send the box where it needs to go.
Just remember: The gift needs to be mailed out by Dec. 20.
For parents who want their child added to the list, beanelf.org has all the information they need.

Project date: 23 February, 2015 to 28 February, 2015
Project details
The project was part of a national level Go-Kart championship named "Elite-Karting championship" organized by Elite-Techno groups. The aim of the project was to build a Go-Kart from scratch and compete nationally.
Although this was our university's first student event, we were excited. We built a team of 12 students who had exterpise in their specific fields and contributed greatly in acheiving promising resutls during the event.
The event (which was a 5 day event) took place in Bhopal, India in 2015.
Around 75 teams competed nationally for various spots throughout the event.
Team Organization and Responsibilities
Within the team, I was responsible for tasks such as Vehicle Dynamics, Material procurement and External styling of the vehicle. Alongside me, vineet kumar pant, Aman Dhyani had an active role to play assisting me and moving forward as a Team.
Ankit Pundir and vineet kumar pant also headed the simulation department which was responsible for designing and performing all the simulations in CATIA and ANSYS.
Saurabh Khanduri and Ronit Sukhija headed the role of Team Captain and Team racer respectively. Saurabh's decision taking skills and Leadership qualities landed him in Indian Navy which the team is proud of.
Probably, one of the most important members was Randhir Kumar Sharma whose expertise in Manufacturing and Craftmanship motivated us everyday to work towards this awesome built.
Apart from this, there were more team members whose curiosity and learning nature motivated us to constantly move ahead.

MdDialogModule
Official Documentation
The MdDialog service can be used to open modal dialogs with Material Design styling and animations.
A dialog is opened by calling the open method with a component to be loaded and an optional config object. The open method will return an instance of MdDialogRef:
let dialogRef = dialog.open(UserProfileComponent, {
height: '400px',
width: '600px',
});
The MdDialogRef provides a handle on the opened dialog. It can be used to close the dialog and to recieve notification when the dialog has been closed.
dialogRef.afterClosed.then(result => {
console.log(`Dialog result: ${result}`); // Pizza!
});
dialogRef.close('Pizza!');
Components created via MdDialog can inject MdDialogRef and use it to close the dialog in which they are contained. When closing, an optional result value can be provided. This result value is forwarded as the result of the afterClosed promise.
Several directives are available to make it easier to structure your dialog content:
| Name | Description |
|---|---|
<md-dialog-title> |
[Attr] Dialog title, applied to a heading element (e.g., <h1> ,
<h2> )
|
<md-dialog-content> |

OUT OF SIGHT
Reviewed by Harvey Karten, Ph.D. Universal Pictures Director: Steven Soderbergh Writer: Scott Frank, novel by Elmore Leonard Cast: George Clooney, Jennifer Lopez, Ving Rhames, Don Cheadle, Dennis Farina, Albert Brooks
At the beginning of a 10-round prizefight, two contenders come out and touch gloves as a sign that they don't really mean each other harm: it's just part of the game. Then they pummel each other as though to belie their act of camaraderie. By the end of round 5, one guy's eye is virtually closed, the other is bleeding from the nose. The crowd cheers. What would happen if, before coming out for the sixth round, each fighter called a half-hour time out and both existed for the nearest luncheonette for a cappuccino and a chat? "How's your little baby doing?" says one, while the other responds, "Is your mother OK after her surgery?" Would they still have the same fight in them when they returned to the ring? Hardly.
This is the premise of "Out of Sight," a crime story mined by novelist Elmore Leonard--also known for "Get Shorty"--for comic resonance. It's a metaphoric boxing match between a charming bank robber and a beautiful federal marshall who is chasing him and rounds up getting pursued instead. He, Jack Foley (George Clooney), has just broken out of prison where he is serving a thirty-year sentence; she, Karen Sisco, is a federal cop who can get a jump on her career by bringing him in but is hindered by her romantic feeling for him. As the novelist states, "Like if she were to make a T with her two hands, calling for a time-out....It would be okay then to say hi, how're you doing? They stand there talking, polite to each other. He might say something about her shooting at him and she'd say heah, well, you know....You have time for a drink?...The next time she saw him, she'd cuff his hands behind his back and take him in."
Director Steven Soderbergh, known for spare statements as in his celebrated "...sex, lies, and videotape," and for the dry humor of that great monologue, "Gray's Anatomy," helms against type by finding a broadly comic tone in this movie version of "Out of Sight." Filmed in bold color by veteran Soderbergh cinematographer Elliot Davis, the film comes right to the point by opening without credits on a bank robbery that that is so smooth and confident that you need not wonder that the perp is a veteran of 200 such escapades. Caught when his car would not start, he is given a 30-year jail sentence as a incorrigible criminal, then manages to break out--but not without interference from federal marshall Karen Sisco (Jennifer Lopez), who happens to be on the scene. Sisco is overpowered and, in the key scene, is tossed into the trunk of a getaway car together with Foley. Their conversation proceeds like anyone's dream first-date, leading to instant Stockholm syndrome. The two are in love, an unlikely pairing which provides much of the comic impact of this delightful caper movie.
A good deal of the story is centered on the way both Foley and Sisco live in anticipation of their next meeting. As with any good romance film, a great deal is put in the way of their getting together, not the least being that she is obligated to bring Foley in while he needs both to avoid her and to consummate his attraction. Soderbergh films with striking hyperrealism in one scene, as Foley and Sisco get together for a romantic interlude in a dazzling night club and, as they converse they fantasy the inevitable conclusion to the evening's dalliance. Soderbergh also makes Elmore Leonard's novel cinematic by use of flashbacks, frequently dashing from some of Anne V. Coates's briskly edited scenes to incidents involving Foley's stay in the Florida prison.
For George Clooney and Jennifer Lopez, "Out of Sight" stands as their best work. Clooney has lost his signature cocked-head, smiling mannerisms while Lopez, who substitutes for the blond agent of the book, conveys her conflict with every move. In the convincing and jocose side roles, Dennis Farina portrays Karen's understanding dad, Steve Zahn a drug addict who talks too much, Albert Brooks a multimillionaire jailed for insider trading who confides too readily in his jailmates, and best of all Ving Rhames as Buddy, famous for confessing his crimes to his sister who promptly turns him in each time.

Like so many of Isaac's attempts to apply his imaginative vision to life, this orgone box was compromised by his poverty and his many interests. It was too obviously a homemade, bargain-basement orgone box. It looked more like a cardboard closet or stage telephone booth than it did a scientific apparatus by which to recover the sexual energy one had lost to “culture”. Isaac's orgone box stood up in the midst of an enormous confusion of bed clothes, review copies, manuscripts, children, and the many people who went in and out of the room as if it were the bathroom. Belligerently sitting inside his orgone box, daring philistines to laugh, Isaac nevertheless looked lost, as if he were waiting in his telephone booth for a call that was not coming through.
Alfred Kazin on Isaac Rosenfeld, quoted in Adventures In The Orgasmatron : Wilhelm Reich And The Invention Of Sex by Christopher Turner (2011)

If you want to use all the components, you can just include and use dist/js/ace.js
or the minified version in your app.
Ace's javascript files are placed inside js/src
.
To add/remove components you should edit
js/src/index.umd.js
So for example if you don't want the Custom file input, you can remove the relevant line from js/src/index.umd.js
and build a new dist/js/ace.js
by running the following commands:
npm run js # builds dist/js/ace.js
npm run js-min # minifies ace.js
To see more commands like that, please view package.json
file.
There is also the app/browser/demo.js
file which you do not need and is only used to handle some stuff in Ace's demo.
For example to handle settings box such as changing sidebar theme, switching to RTL, etc as well as responding to sidebar or widget(card) events in demo ...
Most of Ace's demo pages use one or more plugins such as charts, date/time picking, etc and the relevant code to initialize those plugins for that page is inside:
<EMAIL_ADDRESS>For example for dasbhoard you can find it here:
<EMAIL_ADDRESS>You can check these files to see an example of how a plugin is used but you don't need to and should not include these files in your app.
The list of plugins used in each demo page can be seen here:
<EMAIL_ADDRESS>For example for dashboard you can see that
<EMAIL_ADDRESS>contains:
{{{include-js<EMAIL_ADDRESS>{{{include-js files="sortablejs"}}}
which means dist/Chart.js
file from Chart.js and the main Javascript file from SortableJS plugins are used in Dashboard page.
include-js
and include-css
are custom Handlebars helpers used to specify and include requirements of each demo page during development of Ace.You don't need to and should not use them.
Ace's demo can be viewed both by opening index.html
or running the app using the following command:
node index.js
index.js
file along with the app
and build
folders are just for running and generating Ace's demo app and you don't need them


Kristaps Porzingis hilariously forgets which locker room was his, nearly followed Knicks in
by TSD StaffMavericks big man Kristaps Porzingis had spent the entirety of his career playing for the Knicks up until he was traded back in February, and apparently, he still feels to believe the friendly confines of Madison Square Garden are home, at least on some level.
Fans sure didn’t make him feel that way, as they booed him both before and during the game — even breaking out an “a–hole” chant at one point in the game (watch here).
As for Porzingis, though, well, he nearly walked to the Knicks locker room at halftime, as this funny clip shows.
Wrong way, bro.

Orlando homicide detective uses commercial DNA website to solve cases
by Alexa Lorenzo , Katlyn Brieskorn, WFTV.comORLANDO, Fla. - In what could be the first approach of its kind, an Orlando homicide detective convinced a judge to sign a warrant, so he could search a commercial DNA website to generate familial leads in a murder investigation.
Detective Michael Fields used commercial DNA site GEDmatch for assistance on a homicide investigation in 2018, but at that time there were no restrictions placed on law enforcement personnel seeking information.
The site changed its policy in May of this year, however, and decided it would not easily release information to law enforcement agencies, the type of information that previously had helped Fields crack a decade-old homicide case.
“It was sitting in the file, and we didn’t have a match,” said Fields.
The case went cold. The DNA sample from the 2001 slaying of University of Central Florida student Christine Frank led police nowhere.
More than 15 years later, Fields said he turned to commercial DNA sites for help.
Fields first tried with Ancestry.com and 23 and Me, then he finally looked into GEDmatch, which gave him what he needed.
“When I got the results back, I was floored,” Fields said.
When detectives ran the DNA sample from the crime scene, the database linked it to three people believed to be distant cousins of the killer.
Detectives were able to track down their suspect and make an arrest.
But now, when he wanted to use the same site in a different case, Fields learned GEDmatch had changed its privacy policy, but he got around it.
“I just applied the same thing we’ve been doing for years to this new thing,” Fields said.
He wrote up a search warrant of more than 50 pages.
“Since it was the first search warrant ever written against a genealogy website, I made sure every 'i' was dotted, every 't' was crossed,” Fields said.
A judge signed it, and GEDmatch responded within 24 hours, letting Fields push aside those privacy settings and search the website's database of about 1.5 million people.
He wasn’t able to provide a lot of detail about the case, but Fields did say the DNA data did generate some leads.

If it is for a large work, arsenic and pulverized tartar thrown into melted silver, makes the silver runny. This is enough for silver. But for subtle work, you need bronze, filings, copper, even antimony, sublimate, all neatly ground. All of this makes a mass that does not get smaller. If the plaster is good, you do not need to add crocum for silver, but one puts in more feather alum. It is also necessary to add melted common salt, and some saltpeter and the aforementioned drugs: arsenic, tartar, bronze, copper filings, antimony &

Flowers can also be kept in their same beauty in distilled vinegar in a vase, well—sealed so it takes no draft, well—sealed with wax and mastic. Carnations and roses, the residue of common vinegar makes them rot. If the sand makes dust, and sticks to the flowers and hardly comes off with a brush, it is no good. The most lean is the best.

River sand, that is washed by the current of water, is good when strained in a cloth to make the powder compact.
This is a rare secret, and which is pleasing for decorating tables, rooms, studies out of season when winter denies you flowers. Be advised to pick them when they are in full vigor and still growing, because if you take them when no longer in bloom or when they are starting to wilt, they will not keep. Having therefore chosen them, take some sand, the leanest and driest you can find, that must be very well ground, like the one goldsmiths use to sand enamel, or like the one used for engraving. But this sand must not be dusty at all, nor must it stay on your hand or leave a trace when you have ground or poured it, because it is

Using the GUI¶
The Analysis tab provides an interface for the shot detection and 3D reconstruction using the previously developped methods.
The first form at the top should be filled with the experiment parameters such as the shot media type (string), the sample name (string) and the input pressure in psi (float). Those data will not be used for the analysis but will be exported in the final report to better identify the conditions of each test.
The form in the middle is composed of two columns: one for the top camera at the left and the other for the left camera at the right.
The “Set mask” button opens a new window to select the mask size to remove reflective surfaces from the analysis. The mas only fills a part of the picture with 0’s so that it is not accounted for in the detection procedure. You can move either the mask width or height slider to chose the mask size.
The following parameters should be entered for each camera:
The camera calibration folder: containing the files generated by the calibration procedure for each camera. The files hould be named “cam_top” and “cam_left” for the top and left camera respectively.
The picture folder: each picture should be named with the following format “Name_picNumber” where picNumber is the picture number ordered following the shot sequence. Only .jpg and .tif format are supported yet.
First picture ID: (int) corresponds to the first value of picNumber that should be considered in the analysis.
Framerate: (float) is the camera number of frame per second.
Screen width and height: are the camera screen width and height in pixel (without any resizing)
Acquisition width and height: are the width and height of the acquired picture in pixel. Warning: it is not necessarily the effective picture pixel size as it should be the dimension written on the information banner (and should therefore not account for the length of the banner). See the picture below for more explanation.
Detection threshold: is the threshold for which the value of the diference between the actual image and the background image should be considered to belong to the shot.
The final bottom section is composed of several analysis option. The first one is the method to use, either accounting for perspective or not, with an optimized reprojection error or not. If the “No perspective” option is gathered, the two forms bellow will appear. A float giving the pixel to cm ratio should be entered.
The “Batch mode option” provides a way to make an analysis on a large number of experiments, using the same analysis parameters (coul dbe usefull for repeatability analysis). When ticked, the user is asked to ender the folder path containing all the analysis to be performed. Each analysis folder should contain two folder (one for each camera), with the name given by what was input in the “Picture folder” form of each camera.
The batch set-up button opens a new window to set the post processing parameters to be used on the whole batch. Please refer to the Post-processing section for more details.
Finally the “Show detected point” option will superimposed the detected shot positions on each shot picture to check wether the shot detection threshold and the masking area for each camera should be adjusted.

Continuous Integration
"continuous integration (CI) implements continuous processes of applying quality control - small pieces of effort, applied frequently." -- Wikipedia
"continuous integration (CI) implements continuous processes of applying quality control - small pieces of effort, applied frequently." -- Wikipedia
Using the 2GB fat Java continuous integration servers is often overkill for the feature set you really use. Often you don't even need Java or similar dependencies on your server to build your project or you don't have the memory or space for that extra process. That is where generic-ci starts offering a lightweight, extremly simple and customizable solution.
You can use generic-ci as a user or as a server. To use it as a server or globally for every user, install one of the provided packages. As a user, just clone the repository itself to somewhere in your home directory.
generic-ci provides a setup utility, which sets up a configuration initially. To start the setup just type: genci setup The setup will ask you some question and will afterwards initialize your configuration. Please read the instructions carefully! For more configuration options, have a look at the generated configuration file and modify it to your needs.
generic-ci provides the ability to use the test environment directly to also execute releases. This may help to utilize the tested environment. To trigger a release, type the following command: genci release example-config The release is then scheduled and executed next time the crontab executes generic-ci.
To get an easy web interface for generic-ci, you can let generic-ci generate html files. This way, it is easy to have a stable and secure web interface deployable in a chrooted web server. Set up another cronjob: * * * * * genci web example-config /var/www/htdocs/builds/example-config Again, replace "example-config" with your configuration file's name. As the last argument, specify an existing directory, where the html files should be generated to.
Embedding the current build status in your website
The web interface also generates branch-widget.html files for every branch (e.g. "master-widget.html").
You can use an iframe to embed the current status in your own website. Look at this site as an example.
Monitoring your project
generic-ci already provides a web interface which is optimized for a monitor. If you
have a monitor in your room, point its browser in fullscreen mode to your generic-ci
webinterface, appended with "monitor.html", like that:
http://builds.example.com/monitor.html
generic-ci provides a plugin system to extend its capabilities with various features.
Look at the sample configuration file for an example how to configure plugins. At its core
the plugins are just executables which will be executed before and/or after every build.
generic-ci provides various environment variables which can be used by the executables
to perform various actions.
generic-ci bundles some basic plugins. Look at the sample configuration file for more informations.
For further help, please send an email to tobias@sarnowski.io.

--- layout: post title: "Moduler CSS" date: 2016-01-07 categories: CSS --- Four popular methods for writing modular HTML and CSS.
The five categories it defines are: Base, Layout, Module, State and Theme.
Base rules are applied directly to element selectors, descendant selectors and pseudo selectors. These wouldn’t be applied to classes or IDs as they’re default CSS rules. Resets are a good example.
Layout rules are for the major components of a site like the header, footer, sidebar, or main- content. These will often have CSS applied to an ID like #sidebar or #header. Classes can also be used.
Minor layout components are considered as modules and typically live inside the major layout components. A content box inside a sidebar is an example. Sometimes it’s hard to tell the difference between major and minor components. The more a component is repeated, the more likely it’s a module. Navigation bars and widgets are good examples of modules. Here, we want to stick to classes.
State rules apply to changes like hovering over a navigation item or collapsing and expanding an accordion menu. State rules are similar to modules, but differ in several ways. They can apply to both layout and module styles and often indicate a JavaScript dependency. More importantly, they apply to changes that occur after the page is rendered. Like modules, they should be developed to stand alone with styles being inside a single class selector.
Theme rules are typically used least on a single project and aren’t considered one of the core categories. These define things like colour and typography, and exist so user preferences can overwrite any of the above rules.
Another important concept to SMACSS is its naming convention. As Snook mentions, “a naming convention is beneficial for immediately understanding which category a particular style belongs to and its role within the overall scope of the page.” The following convention is suggested for each of the four core categories: Base Nothing needed Layout l- or layout- prefix State is- prefix, as in is-active or is-hidden. When applied to a module, you should include the module name as in .is-tab-active Module Modules just use module name (.box) instead of trying to prefix each. However, related modules (submodules) receive a consistent prefix to help organise them (.box-border, .box-background, etc)

Memorial service set for former Madison mayor Joel Skornicka
by Stephen CohnMADISON, Wis. - According to an obituary, memorial services have been scheduled for former Madison mayor Joel Skornicka.
The obituary said a service will be held at Olbrich Botanical Gardens at 5 p.m. Thursday, Dec. 5.
A visitation will also be held from 2:30 until 5 p.m.
Skornicka's family is asking for contributions to his memory be made to the UW-Madison Political Science Department Skornicka Public Service Fund in care of the UW Foundation at 1848 University Ave., Madison, WI; the Second Harvest Food Bank; or the Foundation for Madison Public Schools.
Skornicka died earlier this month of a suspected blood clot.
He received a bachelor's degree in political science from UW-Madison in 1959 and served as assistant chancellor for the University before his term as mayor from 1979 to 1983.

I am a first-year PhD student in the Computer Science Department at Carnegie Mellon University, advised by Prof. Bryan Parno. I am broadly interested in formal verification, security, and programming languages. I am fortunate to be supported by the NSF Graduate Research Fellowship.
In 2022, I was a research assistant in the PLV group at MIT, supervised by Prof. Adam Chlipala. I worked on adding support for runtime metrics to the Bedrock2 compiler, as well as a model checker for the RISC-V memory model.
I graduated from Harvard in December 2021 with a concentration in Computer Science and a secondary in Mathematical Sciences. At Harvard, I worked with Prof. Stephen Chong and Dr. Shrutarshi Basu on verified compilation. Check out my undergrad thesis for more.
In summer 2019, I worked with Prof. KC Sivaramakrishnan at IIT Madras on adding sublinear algorithms to the Owl library for numerical and scientific computing in OCaml. Check out my blog post about it for more.


Collective Excitations
In this lecture we discuss a very simple many body system in which particles are coupled by Hooke’s Law springs. Nevertheless, the quantization of this system has a lot to teach us about the appearance of collective excitations. Introducing anharmonicity causes these excitations to interact.

Quantizing an Elastic Chain
We study a chain of equal masses connected by springs, moving only in one dimension, along the chain. The Hamiltonian is
\begin{equation} H = \sum_{j=1}^N \left[\frac{p_j^2}{2m} + \frac{k}{2} (x_j-x_{j+1})^2 \right]. \end{equation}
We identify $x_j=x_{N+j}$, corresponding to periodic boundary conditions. As usual $[x_i,p_j]=i\delta_{ij}$. To orient ourselves, we solve the classical version of the problem.
The Classical System
You’ve seen this before. The equations of motion are
\begin{equation} m \ddot x_j = k(x_{j-1} + x_{j+1} - 2x_j). \end{equation}
We look for oscillatory solutions with time dependence $x_j(t) = x_j e^{-i\omega t}$, arriving at the matrix eigenvalue problem
\begin{equation}
-\omega^2 \begin{pmatrix}
x_1
x_2
\cdots
x_N
\end{pmatrix} =
\end{equation}
Matrices of this type are called circulant matrices, and arise here because of the translational invariance of the system (including the periodic boundary conditions). Their eigenvectors are given by plane waves $x_j = z_n^j$, where $z_n$ is one of the $N^\text{th}$ roots of unity i.e. $z^N = 1$ or
\begin{equation} z_n = \exp\left(\frac{2\pi i n}{N}\right),\qquad n = 0,\ldots, N-1. \end{equation}
In fact, to make things a bit more symmetrical, let’s take $N$ to be odd and index the $z_n$ using both positive and negative values of $n$
\begin{equation} z_n = \exp\left(\frac{2\pi i n}{N}\right),\qquad n = -(N-1)/2,\ldots, (N-1)/2. \end{equation}
We’ll write $k_n\equiv \frac{2\pi n}{N}$, so that the eigenstates have the form $x_j=\exp(ik_n j)$. Substitution into the equation of motion yields the dispersion relation
\begin{equation} \omega_n^2 = \frac{2k}{m}\left(1-\cos k_n\right), \end{equation}
which is plotted in Figure… Notice that:
- The frequency vanishes at $k\to 0$. This mode corresponds to translation of the system, for which there is no restoring force.
- At small $k$ the dispersion is linear, as we would expect for sound waves.
A general motion of the system can be represented as a superposition of the normal modes
\begin{equation}\label{superposition} x_j(t) = X + Vt + \sum_{\substack{n\neq 0\ |n|\leq (N-1)/2}} \left[q_n \exp\left(ik_n j - i\omega_n t\right) +\text{c.c.} \right] \end{equation}
where $X$ and $V$ describe the motion of the centre of mass.
To make contact with quantum physics, let’s look at this problem from the Hamiltonian perspective. Writing the Hamiltonian

Complex Amplitudes
Sticking with the classical problem, let’s introduce complex coordinates to describe our two dimensional phase space.
Fourier Review
Ground State Wavefunction and Fluctuations
A Reminder about the Quantum Harmonic Oscillator
First hint of special nature of 1D – divergence of displacement.
Excited States: Feynman–Bijl Formula
For the harmonic chain can show that acting with $\rho_q$ on the ground state gives an excited state
Is it useful to do this in lectures. Other non-trivial example is Fermi gas
Nonlinearity and Interactions
This is a good excercise in writing things in Fourier modes Could compute phonon lifetime using Golden Rule
