Well, since it looks like I may be the first to be getting in a response to this news - I'd like to say something positive!

I think that the monitor is not only a good thing, but personally I would even expect it of a well managed free webhost.

Why should a few greedy or careless website-developing members here be allowed to hog 90% of the system resources, so that other members' sites grind to a halt or become unusable?

Not only is this monitor fair to have, but it is also enforced very non-aggressively. For 2 breaches of the limits, members can un-suspend themselves each time. And even for the third breach, which requires a support ticket, un-suspension is still possible (I don't know what happens after that, though! ;) )

Ideally, we would have some sort of usage meter in our panel as well. Most novices won't really know what set-ups in their site will cause what system demands. Maybe that isn't practical to implement, or maybe it will be introduced later.

But if, as Bryon explains, putting demands on "a system's processing power for long enough to be suspended will only happen if you are doing something not normal" - then it seems that most of us shouldn't even be affected by this new monitor. At least, not in any detrimental way.

Sounds like a fair plan ...

Now I just need to avoid

for( i=1; i<=array.length; i-- )
{
// my for loop
}

EDIT/ADDITION: The above code is an infinite loop.

From what I gathered it sounds like it's got a bit of a time-delay, so unless it's got an INSANELY long array or has lots of operations to do on it, it -shouldnt- trip high-resource-usage

If a user exceeds any of these limits for longer than 60 seconds, they will have a suspension applied to their account.
Obviously keep the usage of it down though, just in case :)

I can say something similar is in the works.

That probably wouldn't result in a suspension. :p

Perhaps we should organise a competition to see who can write the most resource-hogging software?

Ist Prize: 1 year's free ban! ;)

Code:
While (1)
{
echo "This might be a titch resource intensive";
}

But yeah, honestly even that's enough to qualify cause it doesn't matter how long the echo takes, it's going to suck up as much cpu as possible cause it'll keep looping as fast as possible XD

Im sorry did your conversation go from, you better not use allot of resources, all the way to lets see who can use the most? lol

The resource limit thing is 32MB right?

Hmm. That's sucking up the CPUs, but you haven't made much of a demand on memory or concurrent processes, now have you?

4/10 - Good effort, could do better. ;)

I just want to know how possible it is to use Wordpress without being suspended. Anyone with WP have any feedback so far?

PHP:
while (1)
{
echo "This might be a titch resource intensive\r\n";
$variable = $variable."this might be a titch memory intensive.... after a while... \r\n";
exec("php thisfile.php");
}
:dunno:

Great to see that the admins are setting reasonable resource limits that help ensure everyone gets a slice of the pie. Well done guys!!

I remember many moons ago I wrote a little program on the mainframe at work to do a Christmas present draw for my extended family. Had a logic error that didn't properly catch the scenario of where a draw could not be completed (last person left with only themself to pick). Little program took all the batch CPU resources to its knees (ahhh.. them memories!!).

pretty high overuse limits, so it sounds reasonable. It's good to know :)

So if one made a php script that ran for 3 days, used .001% cpu usage, and 10mb of ram, its ok?

like if i did somthing like

O, and the guy above me has hidden links, abusing the system >.>

PHP:
<?
//code to make sure only 1 instance is running.

set_time_limit(0);

while(1)
{
//Do something like ping a site or process a small portion of data

//wait 5 sec
usleep(5000000);

}
?>

Nice'n Fair, just the way I like it.

Code:
$kill_array = array();
function kill() {
  while (1) {
    $kill_array[] = sha1(uniqid(rand(), true));
    echo "Take this Corey!";
    include "kill.php";
    kill();
  }
}

kill();
I believe I will take that suspension now :p

I don't think the server will allow you to override the maximum execution time, but it would be interesting to see just for fun.

If you are actually relying on this working for your site, I think you might want to reconsider your design :p

im not, it was somthing random i thought up. i would rather rely on a cron job if a absolutely needed to.

but i don't see why you wouldn't be able to override the maximum execution time, unless x10 has coded to prevent it?
