Re: Test wafer distribution: Many features, includes res chart

Now I have got mine, having traversed half the globe and still in one piece, I would like to keep it in that condition. I am thinking of sticking it to an object slide. Any advice or experience around?

Re: 5 euro cents. 200x Projection through eyepiece.

A good source for coins with such a "patina" is at the bottom of the laundry machine.

Re: Oscillatoria

Well I remember I once took the ugly green flap from my aquarium and put it under the microscope. It was so spooky to see the algae moving like worms I at first was scared even to look at it. The way I remember it, those were thinner threads than yours. BTW, not much later I emptied the aquarium for...

Re: Forum upgrade completed

I have had similar issues with wiki-software. Finding the code and adapting is one approach indeed. Only, when updates are frequent, it has to be redone every time again. Instead I wrote a simple script inspecting every page in the database and perform the changes there. This post seems to be doing ...

Re: Bugs in forum upgrade conversion

Just so you know, I have encountered a couple of bugs in the upgraded forum: I was too optimistic when I thought that all saved URLs would still function properly. It turns out that there has been a slight change in the use of anchors, so that old format URLs that reference specific postings will n...

Those jaws look piercing rather than scissorlike. Doesn't that say: predator?

Re: Forum upgrade completed

Especially the banner is higher than it needs be. Noted, thanks. I'll look at tightening that up. Unfortunately a lot of the vertical space is required by buttons and links whose placement is determined by the board's "style". In principle the style could be edited to place those anywhere, but in p...

Re: Forum upgrade completed

It seems that the messages scale better to the width of the screen now. They look spacier and wrap well sofar. If anything, the top matter takes up more than half the useful height of my screen (the forum contents or the individual posts). Especially the banner is higher than it needs be. Apparently...

For SEM, spores are not dehydrated. They are by nature in that state. I never heard they get deformed in the process. The wall material is exceptionally hard. For taxonomic purposes SEM photos are excellent since the smallest details show up. For recognition the SEM photos have limited value since f...

That is a very good spore photo (left). Strange, how the folds look much thinner than in UV and on SEM-photos.

I’m pretty sure that it is filix-mas.
I agree.
