I wanted to make a chart showing the history of far-left organisations in my area. Anyone remotely familiar with the subject will know that such groups quite frequently undergo repeated splits and mergers (for those not familiar, think the People's Front of Judea and its associated splinter groups in Monty Python's Life of Brian) .Is there any kind of software that would be particularly suited to creating this sort of visualisation? I wanted to end up with something looking like this. Obviously it would be possible to do in any basic image editing program, but I was wondering if there was specialised software for this sort of thing. -- 149.135.146.88 ( talk) 09:33, 11 October 2012 (UTC)

The formula for computing double declining depreciation in Excel is relatively straightforward:
DDB(Cost, Salvage Value, Useful Life, Current Period)
So, for example, DDB(80000,8000,5,3) gives you 11520, the depreciation in year 3.
However, I cannot find a function that will give me accumulated depreciation (ie, the total amount of depreciation in previous periods, and the current one). In the above example, the answer would be 62720, which is basically DDB(80000,8000,5,1)+DDB(80000,8000,5,2)+DDB(80000,8000,5,3). Is there any way I can easily and automatically compute total accumulated double declining depreciation to date? ΣΑΠΦ (Sapph) Talk 12:11, 11 October 2012 (UTC)

I've copied content from computer to computer for the last seven years, and whenever I backup my Windows 7 computer's hard drive, I notice the existence of multiple thumbs.db files. I've read Windows thumbnail cache, but just to be sure, I wanted to ask — do I understand rightly that deleting these images should have absolutely no effect on my system? I'm not going to waste time finding them to delete them, but I've always been mildly concerned when I get a note warning me that a thumbs.db file won't properly copy from place to place.

Shouldn't ls -d show me the directories in a directory? (it shows .) Why is it like that? OsmanRF34 ( talk) 17:05, 11 October 2012 (UTC)

Note that this question has a legal dimension, but I'm not asking about the legal side, ie. whether something would actually stand up in court. I'm only wondering if there are any holes in this idea from a computing point of view. So let's say I have written a song, and I email the lyrics/ mp3 file to myself, and try to use this to prove copyright. If someone doubted it, I could just log in to my email, and show them the date of posting. Can this be faked? As a side question, I am curious if anyone knows of actual cases involving this, but just for reading interest. It's not legal advice, because I am a long way from having anything to worry about at this stage - just interested firstly in the forensic side, and (while I'm on the topic) if anyone has come across any news items on the legal side. From the legal point of view, I don't care which jurisdiction, just interested in any such cases that have made the news/ blogosphere. IBE( talk) 18:37, 11 October 2012 (UTC)
Thanks everyone for the help. Feel free to add more. Also, I'm typing during a coffee break, so haven't had time to read it in full, but it looks clear and quite comprehensive. Just adding a thankyou note in case I'm caught up and have to read the full thing from the archives. IBE ( talk) 05:06, 13 October 2012 (UTC)
I have a website (php/html) and would like to translate it with poedit. In order to do so I need to write all texts (which are displayed on the site) as: <?= _('Text') ?>. Are there any tools/scripts that help me to find all such "text" in an html file or that find any non-replaced text? bamse ( talk) 19:33, 11 October 2012 (UTC)
