How do I make this script that heats up my CPU safe


How do I make this script that heats up my CPU safe

around this issue To make the script safe I recommend setting a cut off temperature for your CPU. You can check the temperature of your CPU using Pythons inbuilt psutil
code :
import psutil
print(psutil.sensors_temperatures())
{'coretemp': [shwtemp(label='Package id 0', current=55.0, high=82.0, critical=100.0), shwtemp(label='Core 0', current=35.0, high=82.0, critical=100.0), shwtemp(label='Core 1', current=34.0, high=82.0, critical=100.0), shwtemp(label='Core 2', current=55.0, high=82.0, critical=100.0), shwtemp(label='Core 3', current=34.0, high=82.0, critical=100.0), shwtemp(label='Core 4', current=35.0, high=82.0, critical=100.0), shwtemp(label='Core 5', current=34.0, high=82.0, critical=100.0)]}
critical_temp = 80.0
keep_heating = True
cpu_temperatures = psutil.sensors_temperatures()

for cpu_temp in cpu_temperatures['coretemp']:
   if cpu_temp >= critical_temp:
       keep_heating = False    

while process_count <= multiprocessing.cpu_count() and keep_heating:
    process_to_be_not_seen_again = multiprocessing.Process(target=round_robin_count)
    process_to_be_not_seen_again.start()
    process_count += 1
    some_function_to_recheck_heat()

This might help you Oh good lord you're screwed. Take a look at this
Basically, there are so many things you want to strip out. Plus, there's stuff that's valid, but could be used in malicious ways. What if the user wants to set their font size smaller on a footnote? Do you care if that get applied to your entire page? How about setting colors? Now all the words on your page are white on a white background.

wish help you to fix your issue Im looking for a regex to make sure noboy haxes in stuff I dont want in a guesbook I made in PHP. Such as, scripts, sqlinjections, html etc. But still I want the users to be able to use as many chars as they can (ex :)(/?!.,"&-_) without doing the site less safe.

seems to work fine First of all. Use PDO with bind parameter. Then you don't have to worry about injections.
mysql_real_escape_string returns the escaped string and should be used before constructing your query. Use is as so:
code :
$password = mysql_real_escape_string($password);
session_start();
include("lib/conn.php");

//using isset to avoid warnings.
$email = isset($_POST['user']) ? $_POST['user'] : null;
$password = isset($_POST['password']) ? $_POST['password'] : null;

//check if values are not null
if ($email !== null && $password !== null){

    //escape email
    $email = mysql_real_escape_string($email);

    //retrieve password by email and limit 1 result
    $query = "SELECT password FROM register WHERE email = '{$email}' and                         status = '1' LIMIT 1";

    //run query
    $result = mysql_query( $query ) or die ("didn't query");

    //validate if query run correctly
    if (!$result) {
        echo 'Could not run query: ' . mysql_error();
        exit;
    }

    //fetch row
    $row = mysql_fetch_row($result);

    //validate result
    if ($row['password'] == $password){
        $_SESSION['ocer']=$email;
        header("Location: admin.php"); 
    } else {
        header("Location: index.php?l=1");
    }
}

I wish did fix the issue. You aren't checking the length of `text'.

I hope this helps . Neither file extension nor mime type can give you 100% security that you are dealing with a image file. But as long as you're not going to execute the file (e.g. by using include()), that is not a problem and you do not need to check for PHP code or anything else. The only security breach imaginable using a forged image file would be something that exploits the browser's rendering engine. This is impossible to protect effectively against from server side and is the browser vendor's responsibility.
So, as long as you make sure you use is_uploaded_file() and move_uploaded_file() when handling the upload, you should be fine, at least on the image format front. Make sure you read @bobince's post below and follow the link, it contains a bunch of great information on other security aspects when dealing with files.
