I'm looking into redoing my map projection for 3d rendering, uh, thing, and that means among other things using my two improved projections.
04:27
<~Vornicus>
Which means doing 3d renderings of the pixel shapes again, for one thing.
04:29
<~Vornicus>
but I don't actually /have/ a 3d rendering toolchain any more, so this is a challenge.

Well, it's a confluence of factors. The big one is that I'd been using POV-Ray. that doesn't work at all on modern macs, and even on windows it's ridiculously slow and not at all designed for the things I intend on doing with it.
05:25
<~Vornicus>
Never mind that I've at least partly forgotten how to use it.
05:27
<~Vornicus>
On the other hand, Sketchup seems to have entirely different assumptions than I do and I don't know how to hand it large piles of data, and Blender is completely impossible to understand and again I don't know how to hand it large piles of data.
05:28
<~Vornicus>
and I don't know any othersystems, which is not very conducive to their use at any time approaching "soon"

Vornicus: it might be worth trying blender again, allegedly they have put a modicum of effort into changing the UI to not be as viciously user-hating as inhumanly possible (NB: I haven't actually /tried/ it, so for all I know it may still harbour a barely-hidden urge to slowly feed you and your firstborn feet-first through a wood chipper while forcing you to listen to justin biber songs)
10:01

I should look into it. Really though I have a big hunk of data and then I need to light it and camera it and that's that.

hi! I'm wondering. the FAT (file-allocation table), is that just the bitmap over free/used blocks in a filesystem?
11:08
<@gnolam>
That and metadata.
11:09
< simon``>
the educational operating system Buenos which we use at university has a bitmap allocation table that only contains bits signifying whether the block with the corresponding position on disk, as the bit's position in the BAT, is allocated.
11:11
< simon``>
I wonder what metadata, but I can read about that. thanks!

simon``: What file the used blocks belong to, notably.
12:37
<@Namegduf>
Filename.
12:38
< simon``>
ahhh, of course. so the FAT is the blob of metadata for each file/directory
12:38
<@Namegduf>
It includes a blob.
12:38
<@Namegduf>
For each.
12:38
<@Namegduf>
There is not a FAT per file/directory.
12:39
< simon``>
oh. there is (at least) a filesystem block per directory, but this isn't the FAT.
12:40
< simon``>
this is just the one that lists the content and points to blocks for the particular files. but those blocks aren't the FAT either? so the FAT, much like the BAT (bitmap allocation table) is a big blob of metadata at the beginning of a partition?
12:40
<@Namegduf>
Yes.
12:41
<@Namegduf>
The BAT seems like an incredibly simplified FAT, or part of a FAT depending on whether the rest of this information exists somewhere.

12:57
< simon```>
Namegduf: besides the FAT being duplicated in case of corruption, and being an extension of the BAT, thus allowing quicker lookups than if using a simple linked-list to chain blocks in a file, are there any other advantages to using FAT?
12:58
<@Namegduf>
Every filesystem's FAT will work differently.
12:58
< simon```>
so depending on the amount of metadata in the FAT, it might save reading som blocks if that's all you're interested in.
12:59
< simon```>
(assuming the alternative is putting file metadata in separate blocks, or in the first part of their data blocks)
12:59
<@Namegduf>
It's an abstract concept, a "file allocation table".
12:59
<@Namegduf>
It doesn't refer to any particular design or implementation of such a table.
13:00
< simon```>
right... so one of the few things FATs can be expected to have in common is some lookup table that saves one from a linear search through the disk...
13:00
< simon```>
right?

< RichyB>
You *could* store a free-list instead, if you didn't mind mkfs taking ages and the inevitable DOOM OF ALL FRAGMENTATION that would immediately result.

My camera control software is crashing unexpectedly.
21:34
<&Derakon>
This causes a dialog to pop up in the middle of the screen that a) cannot be moved, and b) always stays on top, saying "whoops something went wrong".
21:34
<&Derakon>
It can't be moved because another dialog always shows up on top of it asking if I want to send details to Microsoft.
21:34
<@Reiv>
Fantastic.
21:34
<&Derakon>
That dialog shows more details in a tiny window, too small to display the contents and which can't be resized.
21:35
<&Derakon>
The details point me to a set of three files with the extensions .xml, .txt, and .mdmp.
21:35

The "XML" and "TXT" files are both binary blobs.

It can be moved, or cancelled, but only after you deal with the dialog on top of it.

I really don't understand why MS thinks it's a good idea to deny all mouse events to dialogs that are not the top dialog.
22:20
<@celticminstrel>
More annoying is when there's a modal dialog up, and it somehow manages to get behind the window that it's attached to. I'm sure I've had that happen once or twice... though I think WINE was involved...
