• Quicker alternative to gnome-screenshot? (no animation!, quick!, no frills)

  - by humanityANDpeace

  I want to take screenshots in Ubuntu. This is normally no big problem with the standard gnome-screenshot program is working good. But just now I ran into trouble because I need to take a screenshot of some window which appears only for about 0.5 seconds. The Problem is that the gnome-screenshot is using a (from me at least disappreciated animation when used... this fancy thing kind of delays all and I really cannot manage to take the picture..) So what I need is a "no frills" "down to the ground" alternative to the gnome-screenshot. I really disklike the animation - now because it makes me so much trouble. I also hate it that there appears to be no way to disable it after all. Everybody is forced to accept this animation that looks like "a flash light is going on". I am not against being fancy... but this animation in gnome-screenshot is impacting/reducing its functionality. Indeed in my case the shortly appearing window hides when loosing focus. The animaiton -as I assume- triggers the "loosing of focus". So because of the animation I cannot take the screenshot. Anyhow I have looked for "less frills" alternatives and I have found that shutter is a programme that commes with quite some baggage.. But maybe somebody knows a very light-weight programm that serves the very sinple (do nothing else) purpose of just taking a screenshot...

• Make middle-click close window(s) on unity launcher

  - by humanityANDpeace

  I am looking for a way to achieve this on my 12.04 ubuntu system: Clicking with the middle mouse button on one of the unity launcher icons will close the related windows/programs. At present a middle-button-click causes (when possible) another instance of the same programme to start. There is nothing wrong with that, only I use this less often than I need a quick way to close some programs. The current way is a lengthy 2-click way. Right-click on the icon Select "quit" in the unity-setting in the ccsm (compiz config settings manager) some few things can be changed in the ubuntu unity plugin already. there are other reporst about settings being done in dconf and gconf. What chances are there to tweak the behavior as described above? In Firefox I am used to close tabs by "middle-clicking" on the tabs. In GLX/Cairo-dock I also associate "middle-click" with the close the program. When using ubuntu unity launcher I keep on mistakingly opening new windows, when indeed I wanna close the respective window(s). :(

• Can you tell by the network traffic whether a video was watched or downloaded from YouTube?

  - by humanityANDpeace

  My question is about quite popular YouTube downloaders like youtube-dl (a command line program) or VideoDownloadHelper (a Firefox-browser extension). Comparing two cases: Watching a video on YouTube Download the video using a downloader (to be specific let's assume youtube-dl) Is it possible to tell – for instance by inspecting the network traffic – that the video was downloaded and not "only watched" on YouTube? Maybe one could compare network traffic using programmes like Wireshark? I cannot do that myself, but maybe this will help somebody to answer the question.

• how to reduce size (disk space) of windows 8?

  - by humanityANDpeace

  This questions is about what things I can do to reduce the size that Windows 8 uses. Background For example: At present and with only one programm installed (MS Access 2007) I have a about 15GB of my harddisk space used. I have little space (its a 17 GB partition on a SSD disk). I would like solutions that are like: Remove files not really needed (drivers not actually needed in the system) Help files not really needed (documentation) pagefile.sys (assuming I would have 4GB ram and no real need for swaping) hiberfil.sys (used for hibernate and sleep... I need that. though I would regain about 4GB space) At best I would like to delete mostly files that I would most likely not need. Though I have no good idea where to start there. Since my setup (hardware will not change) I would be willing to delete all the drivers that windows 8 has for hardware I do not have.... The question is about ways to reduce the space that Windows 8 uses.

• How to understand "if ( obj.length === +obj.length )" Javascript condition statement?

  - by humanityANDpeace

  I have run across a condition statement which I have some difficulties to understand. It looks like (please note the +-sign on the right-hand-side) this: obj.length === +obj.length. Can this condition and its purpose/syntax be explained? Looking at the statement (without knowing it) provokes the impression that it is a dirty hack of some sort, but I am almost certain that underscore.js is rather a well designed library, so there must be a better explanation. Background I found this statement used in some functions of the underscore.js library (underscore.js annotated source). My guesswork is that this condition statement is somehow related to testing for a variable obj to be of Array type? (but I am totally unsure). I have tried to test this using this code. var myArray = [1,2,3]; testResult1 = myArray.length === +myArray.length; console.log( testResult1 ); //prints true var myObject = { foo : "somestring", bar : 123 }; testResult2 = myObject.length === +myObject.length; console.log( testResult2 ); //prints false
