checking
In computer programming, bounds checking is any method of detecting whether a variable is within some bounds before it is used. It is usually used to ensure that a number fits into a given type (range checking), or that a variable being used as an array index is within the bounds of the array (index checking). A failed bounds check usually results in the generation of some sort of exception signal.
Because performing bounds checking during every usage is time-consuming, it is not always done. Bounds-checking elimination is a compiler optimization technique that eliminates unneeded bounds checking.

Hello
I want to replace the old single panel rad in the bedroom with a K2 double panel Stelrad one. I think I'm OK in general and relatively sensible (!) but I just want to check the steps involved to make sure I'm not missing anything before starting.

A galvanised pipe on our property burst and water was seeping up to ground level. We dug and found where it burst [it's in the garden but the pipe eventually shoots off under the deck and house], called in a plumber who said he couldn't fix it that day due to other work but temporarily stopped...
As the title really folks. Who uses what to check pressures and carrying out tightness tests? I’m not to keen with the analysers to be honest. I was checking a burner pressure recently and with the analyser it was fluctuating up and down but with the u gauge it was solid?

Hi all,
Does anyone use a checklist when they initially survey a new job?
I mainly do refurb and domestic jobs and I need to be more structured in the way I perform the initial survey.
I'm in the habit of taking photos, a few measurements and figure the system. But often forget to record other...

I'll be putting in new runs of copper for my bath / basin taps that will run under the floor and in the walls.
Will capping the ends off and turning on the water be enough to check for leaks before tiling over?
Recently bought a property with a view to renovate.
Is it possible to check online to see when the existing boiler was commissioned as there doesn't seem to be any paperwork. Worcester Junior 24i, looking at it could be about 5years old.
Thanks

Hi guys, bit of assistance if possible.
I'm in the process of investigating a C1 error ( low fan speed ) but don't want to fork out for replacement fan, only to find out its the control board at fault. ( both of which are feasible )

Hi,
Can anyone tell me the correct method for testing the output from a ignition pcb to the spark electrode ?
I've been roped into looking at my mates Ravenheat 84e tmz. When he creates a demand the pump and fan start but there's no sparking at electrode. I haven't looked at it yet, thought if...
Hi folks
I am about to repair a section of underground drainpipe. As a London plumber, where specialists are aplenty, drainage is something I confess I have very little experience of. I thought therefore I would at least check in with you folks to ensure I am not missing something basic or...
How can I check the burner pressure on a gas cooker, I have tried to put my manometer over the injector but it wont seal properly. Any tips please. Also should the burner pressure be the same on all rings or different?

I'm a...
