Can a mod do this?

I have been reading up on Laser Safety as a preparation for building my first 1W 445, but a lot of Threads which once contained great information now contain a message from a pissed off member who didn't get his way so he edited out all of his helpful content and left. First of all, how bloody childish must you be to cause others to be at a disadvantage on something so important as SAFETY just because you have a grudge with someone here?! :tsk: To these gone members I say good riddance, arseholes like that just bring more drama.

However, that still leaves us with gaps in information, and while some of it can be inferred from posts around it, not all of it is there. Is it possible for a mod to slip back in time and grab this? Or must we start over again; compiling the good info that was left(however piece meal it may be), and compounding on it. I would be glad to go through threads and try to consolidate all that we still have, since some people may not feel trudging through pages upon pages to find Safety info worth it, but I would rather not if it was at all possible to grab it from some sort of Archive... :thinking:

Anyway, I hope someone can shed some light on this, and I hope anyone who reads this will realize the damage that can be done by removing "your contribution," and should a moment like that arise, choose to leave it for your peers, even if you don't like one of them.

Peace,
Isaac

EDIT- example is this thread: Ways To Handle Class 3b and 4 Lasers
Some stuff is there but not all, and I feel it would be very beneficial to be able to restore it.

this is what i found by searching for 20 ways to handle class 3b lasers.

it is pretty much everything that was in bob's post

Safety & Health - Class 3B and 4 Laser Equipment Local Working Rules
in case you dont want to go to the link here is the info copied straight from the site.

1. Do not look into the laser beam. (For any class of laser this is a hazardous practice)
2. The laser must be used within a controlled area from which the laser beam cannot escape. Ensure that the controlled area is clearly defined with signs, and all windows are blocked etc.

1. Within the controlled area and with the laser:
2. There should be a shutter at the laser aperture.

• Use the correct signs, according to AS2211, on laser, at laser aperture and in the area.
• The power supply is keyed, with the key stored safely whilst the laser is not in use.
• Mount laser components well below eye level and secured on the table.
• Use beam stops to terminate the beam and prevent its uncontrolled transmission. Enclose beam paths with interlocked covers so that the laser beam cannot escape from the controlled area.
• Remove specular reflecting surfaces.
• Use low power or neutral density filters during alignment or other set up procedures.
• Wear the appropriate goggles when the laser is energised.
• Illuminated light at entrance and on laser – indicating clearly when the beam is on.
• Avoid hazardous electrical situations.
• Door interlocks may be required to terminate the laser beam when the door is opened.

1. Immediate measures must be taken to remove potentially hazardous situations arising from laser beams that may be emitted due to equipment defect, misalignment or any other reason.
2. Additional working rules, specific for each laser must, where necessary, be documented to ensure the safe operation of the unit.
3. Class 3B and 4 laser equipment must not be operated by inexperienced persons unless under the immediate personal supervision of an experienced licensed operator.
4. Visual alignments or adjustments must not be carried out whilst the laser on full power, unless suitable goggles are used which prevent exposure to the eyes.
5. Users of Class 3B or Class 4 lasers must hold a laser licence or be under the supervision of a licence holder.
6. Accidents and incidents must be reported to the UWA Safety and Health.

Hey, thanks for that link! And all of the info! It hadn't occurred to me that he could have gotten it all from some other site! +1

On another note, however, I am sure there are more threads around that have been Cartman-ized, so is it actually possible for someone to retrieve the info from them? If so, who should we contact if we find something important which has been removed?

Thanks again chipdouglas!

Peace,
Isaac

this is true^^^. so yes i ask the same question... can a mod or admin pull up info that has been deleted by the op?

It mostly depends on who deleted it. If c0ldshadow deleted it, he has the ability to "hard delete." With a hard delete, I do not know if even he can easily retrieve the post/thread.

The Mod's have the ability to do "soft deletes." These can be pulled back up. However, if someone asked for their info to be deleted and it was agreed on by the admin, I would not be comfortable with un-deleting it.

There is nothing in the "lost" threads that is not available from other sources or from other threads in the forum.

Sometimes we do, indeed, have to re-invent the wheel

If its a recent delete you can always pull it up with google cache.
But even with cache, it will only pull up the most recent snapshot
to the link entered.

The problem is if they edit the post, but not delete the thread. I don't think threads are stored through edits.

yes he post has been edited and not deleted.

Depending when the snapshot is taken of the site, you can find
the 'older' version of a post. If too much time passes you will only find
the recent edit as a newer version becomes available in cache:

As an example, some people wipe their first post in a sale thread
and just post 'SOLD'.

In some cases ive been curious to see what the asking price was.
If no new snapshots have been taken by google, I can see
the original post.

I just looked at one today, if I can remember what page, ill post an example.

Finding cached posts from more than 2-3 months is a rare one.
You will only get the latest version of the OP's edit.


Im sure there is a lot more to it than this, but I am by no means
an expert in the matter..

I thought all the old edits were available to be rolled back by an administrator? Word from Avery would be great.

Edits to posts are recorded and available :san:
