I would like to use the thumbnails created by thunar for a small program I'm writing, so as to not duplicate the effort. I speculate the filenames are hashes of the path and name of the original file, but I tried md5sum and sha256sum on the string of path and filename, and it doesn't work. Ie, the outcome doesn't match any filename in ~/.cache/thumbnails/*

So, pls, does anyone know how the thumbnails' filenames are created?

Hi all.

I just had the strangest of problems:

The sub tank mini's air control wheel, became suddenly loose, turning very easily, while up till now it needed much more force to turn. Also it used to click well in each of the three hole(s)-positions, resisting moving from there, while now you can turn it extremely easily. And the weirdest (and scary(?)) part is that at full open, the istick 50 shows 0 ohms, while if you turn it just one millimeter, it shows diff ohms. Something from 1.9 to 3 ohms, (don't know for sure which is the correct value, as I just rebuilt and experimenting, and I'm a relative newbie), changing per millimeter, and it also shows variation if my finger touches the tank

Hi all. I would like to be able to tag open tabs, and then by writing/selecting a combination of tags, ff should offer my only the tabs that match. Does anyone know something like that? Thanks.

Hi all. I recently bought a laptop which came with win8. I will install linux on it, and I was thinking if I can transfer win8 to my desktop, which currently runs only linux, in dual boot. (Or even just win, but I strongly prefer to also keep linux.) It's older motherboard, so unless I'm wrong, it's not secure boot bios. Thanks.

PS: If the above can't be done, I'm also curious: I have an empty external ssd drive. Can I transfer win8 to that, have linux on the laptop, and if/when I want, be able to boot instead from the external ssd in some kind of enclosure, via usb3, into win8?

Can anything or something similar be done, or is it just a total lose and can only be left as is or rem

I'm buying a new comp in the next few days. Can't postpone it. I'll be installing xubuntu. My q is: Should I install 13.10 in a partition, have another for my data, and then overwrite/install again when 14.4 comes (and in this case how big a partition?), or should I just install all in one partition and just upgrade? I am asking cause I've had problems in the past with going to newer releases (though not insurmountable), and being a new comp I want it to start in a pristine condition. Thanks.

EDIT: Or should I go with the betas, and upgrade those?

Hi all.

I am thinking on buying a tablet, for this main usage: Read pdfs, easily take notes from them (ie easily copy, "alt-tab", paste, "alt-tab" back to pdf), and read web sites. My browsing consists of leaving many 10s of tabs open all the time (not necessarily loaded). ie, tabs for news, tabs for one subject, tabs for another subject, etc. I am thinking about a 1920x1200 resolution. Is this as useful as it sounds? Not a must, but I would like to be able to do some minimal programming on it, lisp (clisp/sbcl) and python. Finally, a microsd is a must, and I want good connectivity/data/notes, exchange with my main desktop computer. I generally I don't like at all "the cloud".

So, p

I would like to write a simple program that gives me a random number in a given range, drawn from a given distribution.

For example, if there are 3 possible values, A, B and C, with probabilities 60%, 30% and 10% respectivily, I want the program to return A 60% of the times, B 30% and C 10% of the times.

I was thinking that that is the same as having 60 As, 30 Bs and 10 Cs, and since there is already a random() function that returns a uniformly selected number in a range, I should just input the range, and interpret anything up to 60 as A, anything from 61 to 90 as B, etc.

My q is this: I am not sure if the above i

I will replace my old 23G ssd that is mounted on / with a newer and bigger ssd, using something like dd if=/dev/oldDisk of=/dev/newDisk .My q is can I plug the new ssd in, boot normally, and do that while I am using my computer, or is it necessary to boot from a live cd and unmount them first? (I also have a sw raid1 mounted on /home/user/Documents/) Thanks.

I want to make a macro, called nfor, that automatically creates nested loops and inside of them executes some code. For example,
(nfor '(1 2 3) code) --> (loop for s1 below 1 do (loop for s2 below 2 do (loop for s3 below 3 do code )))

I haven't had a lot of luck with making a macro, but the following seems to work. Is it good/bad, why?
(setf state '(1 2 3)) (defun nfor (s c) (let ((s (reverse s)) (r ,c)) (loop for i below (length s) do (setf r (append (loop for ,(gensym) below ,(pop s) do) (list r))) finally (eval r))))

Running eg: (nfor '(1 2 3) '(print 1))
prints a "

Hi all. I remember using a ff addon that replaces words in place in a page, with their translation in another language, so you can slowly learn them. For example you are reading an english text, and the addon replaces words you have chosen with that of a foreign language. But I can't find it no more :-/ Anyone, please, knows which addon that is?

Can someone please explain to me, why I see screen resolutions of eg 1920 x1200 and then below in the specs or in a review I see the resolution as eg 1280*800 ? Is there some kind of "equivalent" marketing thing? I am thoroughly confused. Please help.
