I'm looking for some Linux alternative to  (image viewer). At best, it should have all its features, the same controls (both mouse and kbd) or fully adjustable, and be as quick.  In particular (this list covers 95 % of my use cases):   Support for many formats, for both input and output Automatic navigation through the directory with Space and Backspace Thumbnails (T) Batch processing (B) Rotating (R, L) Zoom with Ctrl + mouse wheel or + / - Fullscreen (Enter) Image movement with PgUp and PgDn, Home. End Select a rectagle with a mouse -> Ctrl + Y to crop -> Ctrl + S to save as a PNG file Basic image editation - copy, cut, paste, color filters, text input, basic shapes Immediate startup No need to play video or audio   Etc... IrfanView is something like iPhone amongst image viewers, there's nothing to change ;-)  So - what is as close as possible?  Edit: No virtualization please - IrfanView crashes under  in my environment; running virtualized Windows is even further away from being quick; perhaps it could be Java, but native is native.
is a wonderful freeware Windows swiss-army-knife for image viewing &amp; editing.  For me, the key features are fast viewing, simple editing (crop, contrast, brigthness, rotation, resampling), file operations (delete, copy to folder) and extended image information access (exif data) combined in the same interface. Versatile batch jobs are a very nice bonus.  But unfortunately IrfanView is for Windows only, and isn't . What would be the nearest equivalent for linux?
Why do video cables (DVI, VGA) still screw in? I guess I could imagine that there was a time when accidentally disconnecting the monitor would have been catastrophic, though I don't see that being the case today.  Is it just a legacy holdover that they are still secured with screws?  Also, why is it that the video connection is really the only one that is still secured this way?  It seems like the power cable would be a better candidate to be secured with screws.  That really could be catastrophic.  In the end, the reason this question occurred to me is that I've never had a video cable come out when not screwed in, so why the significant security? TikZ 3.0.0 (release) produces strange shadings if used with XeLaTeX and standalone I would like to use shadings in my TikZ graphics together with the standalone package and XeLaTeX, but for some reason it is broken if I try with the new 3.0.0 release (). Any other combination I tried works for me (use for example article class/pdflatex/lualatex/TikZ 2.10). (I'm using a fully updated TeX Live 2013.)

For example:     There's two options here   or     There are two options here   I hear a lot of people say the first line (or something similar), but isn't that incorrect? Isn't it plural and therefore you should use "there are"? "going to do" vs. "going to be doing" Note: this post is different to , which just cites part from somewhere else, without any further analysis and thinking. Furthermore, none of the answers to that post answers my question - the situations where &quot;will (going to) be doing&quot; is more appropriate.   I will be participating in IELTS test next Tuesday afternoon.  In an online class, the teacher says the following at the beginning of the lesson.  I will be using NotePod (pointed out by red rectangle) to write relevant points we talk about today.   I guess &quot;will be using&quot; is more appropriate than &quot;will use&quot; there, right?  A  explains  This &quot;tense&quot; is used for reporting a scheduled activity with special focus on its timing— as if one is standing in the future and experiencing the flow of the time. The focus is on the temporary, ongoing, or repetitive nature of the activity.   I understand the grammar rules of those verb tenses and the difference between this group  I am going to drive home tomorrow.   I am going to be driving home tomorrow.  The former is just convey my activity in the near future while the latter probably makes an implication that &quot;don't disturb me as I am driving in that time&quot; However, in the following situations, I don't see the difference between 2 verb tenses.  Welcome back to this class. Today's lesson is for the IELTS students who are going to be taking the IELTS test. it's for everybody to be honest with you. this lesson is useful for anybody who needs to do some writing.   who are going to take the IELTS test ...

Lualatex and bm package I've updated my latex packages yesterday and have now issues with lualatex. One problem arising for me now is, that lualatex does not print bold characters using the bm package.  When I compile the following MWE with pdflatex everything looks okay, but for lualatex it doesn't:  \documentclass{article} \usepackage{bm} \begin{document} % Bold $\bm{E}$ \\ Normal $E$ % \end{document}   Output using pdflatex    using lualatex    Also trying to fall back to an earlier version of lualatex by using \RequirePackage{luatex85} does not work for me.

Can anyone tell me, what is going on here and what I need to do to solve this problem, since I am quite sure lualatex and bm worked before? No "Login using Google" option in Android app I registered this ID with my Gmail account, and logged in successfully via web browser. However, while I was trying to log in on the Stack Exchange app in my Android Phone, I don't see any option to log in with Google:    I was told that no user was found with my Gmail account. It is amazing that I can log in via web browser, but cannot do so with the same Gmail account via app. How can I do that?  Just to compare, here is a "normal" login screen of another user:    Where did the Google login go and how can I bring it back?  My app version is 1.0.73, phone is Coolpad 8150D with Android version 4.0.3, kernel 3.0.8. I have some troble understanding the Kernel density estimation.  If a consider the next example:  s&lt;-0 z&lt;-density(rnorm(25)) f&lt;-function(i)approx(z$x,z$y,xout=i)$y for(i in seq(min(z$x),max(z$x),length.out = 10000)) s&lt;-s+f(i) s   I expected getting that s is approximately equals to one since I am considering an approximation for the integral of the Kernel density function (that I suppose is also a density). However, I don't get the expected result. Why it doesn's sum one?  The idea behind this is that I wanted to use the Kernel as the density of my data points. I was interpolating to get my explicit function and use with other x values. Or do you know another way to get a density function estimated by fitting? What is the difference between a desktop environment and a window manager? I'm having a really hard time trying to understand what the differences between a desktop environment and a window manager are?  EDIT: From this :  There are basically three layers that can be included in the Linux desktop: X Windows – This is the foundation that allows for graphic elements to be drawn on the display.  builds the primitive framework that allows moving of windows, interactions with keyboard and mouse, and draws windows. This is required for any graphical desktop. Window Manager – The Window Manager is the piece of the puzzle that controls the placement and appearance of windows. Window Managers include: , , , , , etc. Requires X Windows but not a desktop environment. Desktop Environment – This is where it begins to get a little fuzzy for some. A Desktop Environment includes a Window Manager but builds upon it. The Desktop Environment typically is a far more fully integrated system than a Window Manager. Requires both X Windows and a Window Manager.  Examples of desktop environments are , , ,  among others) Equivalent statement of AC or not? Here's a corollary of AC stating that: if there exists an onto mapping $f:A\to B$, then there exists a 1-1 mapping $g:B\to A$. What I'm confused about is that whether or not  AC can be derived from this proposition, in return? I have tried but haven't found a proof. Any help would be appreciated. I am using App Backup &amp; Restore for creating backup of my apps but with KitKat its using the internal SdCard as Storage.  When I explicitly set the external SdCard path it gives the error that it is unable to create folder,  I have also tried with creating folder under android/data/[packagename]/files/ but it is still not able to do the same.  Is there any solution so that apps can use external storage for writing files.  Note : I don't want to ROOT my Phone. Correct position of "only" Which is grammatically correct?

We have a project in Team Foundation Server (TFS) that has a non-English character (š) in it. When trying to script a few build-related things we've stumbled upon a problem - we can't pass the š letter to the command-line tools. The command prompt or what not else messes it up, and the tf.exe utility can't find the specified project.  I've tried different formats for the .bat file (ANSI, UTF-8 with and without ) as well as scripting it in JavaScript (which is Unicode inherently) - but no luck. How do I execute a program and pass it a Unicode command line? I have seen other similar questions but they don't seem to be what I want, please correct me if I'm wrong.  For simplicity: delete the default cube, NumPad7, add cylinder, rotate X 90, then add torus with ext/int 1/0.75 and raise it above the cylinder. It should look like this:.  What I want is to deform the torus against the cylinder, but make it as if it's a projection. This means that, when looked from above, it will look like a normal, undeformed torus (volume changes), but when viewed with NumPad1, it will look like a round-end tube following the curvature of the cylinder, while still having the same round cross-section. To make it worse, my object needs to be deformed by a more complex surface, such as sin(x).  If I'd use soft body, it will look shrinked when looking from above, i.e. it will preserve the volume. If I use shrinkwrap, it either does a projection with its circumference intact, but all flat, or it will project it (similar to what I want), but only the bottom side vertices, like a curtain.  Mesh modifier gets me nowhere since I have to manually tweak the surrounding mesh, and curve modifier also preserves the length/volume, while also squishing the section of the torus at the bending points.  My question(s): is there a way to project (mold) the torus onto the cylinder while preserving it's cross-section? Can this be extended for more complex meshes to be projected or to be projected on?    This is, roughly, what the side view (along Y axis in the 1st pic) would look like after the deforming of the torus:    The unselected shape above is the torus (as it is in the first picture), and the selected shape is what it would look like after the deform, or molding, whatever you want to call it.  And here is what it would look like when seen from above (top view, along Z axis)): i.stack.imgur.com/HVOCo.png (can't add more than 2 pics)  The view would be the same before and after the torus is deformed. Cleaning wax and pesticide from apple skin I love apples. I like to eat them with skin as it has plenty of fiber in the skin. But apples are famous for wax and pesticides on the skin which I don’t want to ingest. I have read many articles on the web and suggestions for removing the wax from the surface.   These suggestions include soaking in vinegar or hot water and other methods. They suggest that soaking apples in vinegar removes the wax that can be seen in the vinegar. I have done that, but never seen any residue of wax in the vinegar.   So I have set aside a new kitchen sink Scotch-Brite scrubber for this purpose and been scrubbing the apple skin under running water before eating. I think this method should remove most of the wax and pesticides. I would like to hear your input. When are "if" and "whether" equivalent? How do I add a Pokestop to an area that has none? It is an area where there are tons of businesses but unless I drive about a mile from my work area there are no Pokestops.   I want to add one since we have 1000's of people in the work area, a lot of them play Pokemon Go, and we all can't leave work to drive a mile away to get to a Pokestop area.   Plus it would be nice to be able to capture Pokemon on our breaks.
