Humour me

<p>What does PDE stand for? I see it used all over this site. I know it will be a simple abbreviation but I CAN'T THINK OF IT.</p>

page directory entry. according to wik. regards miken

<p>Thanks Mike but I still don't see the context with adding it to a critque for example.</p>

<p>U sure they didn't mean, "PSE" (ie, PhotoShop Elements)?</p>

<p>FWIW, PDEs (Partial differential equations) were part of a course in advanced engineering mathematics that I just taught, but I doubt you'll be seeing that meaning very frequently on photo.net. :-)</p>

<p>Tom M</p>

<p>Give us an example of the context...</p>

<p>Partial Differential Equation?<br />Pulse Detonation Engine?<br />Permitted Daily Exposure?<br />Pennsylvania Department of Education?<br />Phosphodiesterases?<br />Present-Day English?<br />Pyridoxine-Dependent Epilepsy?<br />Polynesian Dance Ensemble?<br />Pug Dog Encephalitis?<br /><br />Probably none of those. In this context, it's usually used as the three-letter abbreviation for Pandie Pandie Airport, in Australia. You know, like, "Excellent capture, mate! This HDR is so colorful that it blew me all the way to PDE!" (this is more effective if you say it out loud with an Australian accent).<br /><br />OK, really? I'm betting it's used in place of <strong>Prix d'Excellence</strong>, as in ... first prize, blue ribbon, etc. The dead giveaway is that it's frequently used by members of PN from outside the US.</p>

<p>guess what googling "photo.net PDE" brings up? :)</p>

<p>If I'm any judge of the relationship between Google and this site, it's probably this very post...</p>

<p>We are the "ultimate" in self-reflextive reference :)</p>

<p>You're exactly right, JDM. And now my name is forever associated with the phrase "Polynesian Dance Ensemble." I have <em>got</em> to plan these things better.</p>

<p>Urbandictionary.com defines this as <strong>P</strong>ost <strong>D</strong>efecation <strong>E</strong>uphoria as its first choice. </p>

<p>And I, Matt, will forever be listed as one of the first to use the term <em>reflextive</em>.<br>

It's our density, I mean destiny.</p>

<p>It I na photgraphic instruments context it stands for Photon Deterioration Effect. it describes on a scale of 1,000 what happens to a lens element after it has been used a lot or for a long time. High amounts of photon impingement randomly break down individual glass molecules and resulting in increased internal light scatter, lowering both the transmission value of the individual lens elements and increasing inter-element lens flare, creating a slight "veiling" of the image. </p>

<p>Leica minimizes the effect by using a special carbon compound in the coating around the circumference of individual lens elements and groups. It is one reason why Leica lenses retain their value longer and a reason why busy professional photographers replace gear on a regular basis.</p>

<p>So if you don't have a Leica, then it's best not to point the camera directly at the sun.</p>

<p>Correct, only Leica cameras should be pointed directly at the sun. The requirement is an important part of the functional specification, duly addressed at the very beginning of each design cycle.</p>

<p>I cannot believe it!<br>

Portable Document Format<br>

usually decoded ( opened) with Adobe Acrobat reader. (free)<br>

each kind of printer requires special CODES to the formatting and text is printed properly<br>

EXAMPLE :If you have a hp inkjet and I have an epson laser,<br>

or if you have a PC and I have a Mac,m<br>

and one sends the other a PDF file, you can open read ( view) and print it properly.<br>

============================<br>

there used to be printers - mainly macintosh, that used the Postscript format ( another P)<br>

and my wife does 2 newsletters one in MS publisher and another<br>

In Corel Ventura publisher. She then uses adobe distiller to create a pdf file that the Paople who print the newsletter printinmg l company can print./<br>

stranely, although the HP laserjet uses a PCL/6 language ( not postscript)<br>

We could get a postscript chip for the printer, but the software solution works,<br>

she has to install a Postscript driver so Adobe distiller will make the PDF file.<br>

She is using the same old Adobe Distiller version 5 from windows 3,.1 and it works with windows XP.</p>

<p>So the first part tells you what you asked, but there is a relation between the two..<br>

<p>Tom,<br>

give us one of your PDE's and lets see who solves it first.</p>

<p>PDE = The initials of one of our most prolific members in the critiques/ratings. With almost 36,000 comments and over 66k ratings - and a consistently encouraging influence - his initials are bound to catch your attention if you spend any time viewing portfolio photos here and reading critiques and comments by others.</p>

<p>Some mysteries have no hidden meaning. Sometimes - as Mr. Natural wisely advised - <a href="http://www.rcrumb.com/">it don't mean sh!t</a>.</p>

<p>Considering the amount of different opinions maybe it means <strong>P</strong>ost <strong>D</strong>efinition <strong>E</strong>ratic :) Although I do like the idea that it is a "super poster" trawling through PN replying to as many people as possible.</p>

<p>@Nathan - I'll get my chance today. This is the 1st day of final oral exams for our students. <br>

Do you think I should be mean and give them problems where they can't use separation of variables even if they select a reasonable coordinate system? Then again, maybe I should ask them to demonstrate one of the relaxation methods for numerical solution in Excel. ;-)</p>

<p>How about Please Don't Elaborate? ;-)</p>

<p>I just googled "[sic] define" with brackets because I keep seeing it as part of responses here.</p>

<p>There's about 4 or 5 possible definitions so could someone clear this up as to what this means as part of the context within a post?</p>

<p>How about Pretty Darn Excellent ?</p>

<p> </p>

<p>Of course, the first hits on those letters got me to THIS guys pictures, and he signs off with PDE</p>

<p>[sic] means "I know I made a mistake/misspelt something........I think......I'm not too sure of any abrievations anymore.........Oh and can I take this opportunity to apologise to Matt Laur who will be forever known as the man who invented the phrase "Polynesian Dance Ensemble"....take the shame :)</p>

<p>Might have known it would be the French at the root of the problem John :)</p>
