  • looking for a javascript engine

    - by c0f33.alex
    i'm looking for a js engine to that I can (easily) expose C/C++ functions, classes etc. The API should allow changing exposed values from within C++ (by storing some kind of pointer or reference to an object inside js or so...). I've considered using google's v8 but I'm new to it and don't know whether it will satisfy my requirements. Can someone tell me whether I should stick to v8 or try something else?

  • Sex appeal of computer graphics: movie like UI systems [closed]

    - by anon
    It's well know that 1) the way computers actually work 2) the way computers are protrayed in movies are not the same. In particular (2) looks much much cooler than (1). Where can I learn more about making flashy, superficially useful but deepdown useless fancy graphics UIs like that? It's almost in the realm of "hollywood special effects" -- like fire/smoke/fire, but I don't want natural phenomenon; I want user interfaces. Concrete question: where can I learn about creating flashy, cool looking (though not necessairly useful) user interfaces? [Perferably in OpenGL]

  • SlidingDrawer handle design issue

    - by bali182
    I would like to create a SlidingDrawer, which has a handle like this: Until now i tought my solution was ok, which was: 1.) I created a 9 patch: As you can see, the center part is not strechable, only the two sides (and the height, if needed). On most of the phones i got the desired result, shown above. 2.) Put it in this layout (just pseudo-code): <SlidingDrawer (fullscreen)> <Button as handle (full width, backround the 9patch)/> <LinearLayout as content /> </SlidingDrawer> However, i tested the app on my friend's new Galaxy S3, and the result was something like this: The part, which should be centered, was completely off one side. And i have no idea, why and it bugs me since then. My Question: Is this the prefered way (9 patch with full width) to acomplish the look i want? If not, could someone suggest me a better solution?

  • Deploying a Web Application from the command line

    - by Grant
    Hi. Im looking to deploy a web application on a build server. It is a very small web app and so far i have written a nice little console app that checks out from SVN and then calls msbuild on the .sln file. This of course is not the same as publishing a web app and so far have not found a programatic way of publishing. So my question is this.. After msbuild has run can i simply delete all .cs and .vb files and then deploy? or Should i really try and find a way to publish programatically?

  • Removing final bash script argument

    - by ctuffli
    I'm trying to write a script that searches a directory for files and greps for a pattern. Something similar to the below except the find expression is much more complicated (excludes particular directories and files). #!/bin/bash if [ -d "${!#}" ] then path=${!#} else path="." fi find $path -print0 | xargs -0 grep "$@" Obviously, the above doesn't work because "$@" still contains the path. I've tried variants of building up an argument list by iterating over all the arguments to exclude path such as args=${@%$path} find $path -print0 | xargs -0 grep "$path" or whitespace="[[:space:]]" args="" for i in "${@%$path}" do # handle the NULL case if [ ! "$i" ] then continue # quote any arguments containing white-space elif [[ $i =~ $whitespace ]] then args="$args \"$i\"" else args="$args $i" fi done find $path -print0 | xargs -0 grep --color "$args" but these fail with quoted input. For example, # ./find.sh -i "some quoted string" grep: quoted: No such file or directory grep: string: No such file or directory Note that if $@ doesn't contain the path, the first script does do what I want.

  • How to column-ify an output from a certain program?

    - by mbaitoff
    I have a program that generates and outputs a sequence of simple sample math homework tasks, like: 1 + 1 = ... 3 + 3 = ... 2 + 5 = ... 3 + 7 = ... 4 + 2 = ... a sequence can be quite long, and I'd like to save space when this sequence is printed by converting it as follows: 1 + 1 = ... 3 + 7 = ... 3 + 3 = ... 4 + 2 = ... 2 + 5 = ... that is, wrapping the lines into the two or more columns. I was expecting the column linux utility to do the job using the -c N option witn N=2, however, it still outputs the lines in one column whatever the N is. How would I do the column-ifying of the sequence of lines?

  • Cycling tabs graphically

    - by abernier
    Mac OS X's window manager is composed of: Applications Windows Tabs By default on OS X, you can cycle over applications with the famous ?? shortcut. In addition to this, I use a little utility called Witch which enables cycling (graphically) over windows too(I've defined it on ??). Unfortunately, it does not currently support tabs cycling... Would you have any suggestion for this? I know I already can ^? for this, but I'm looking for a graphical utility where you are not blind during cycling. Thank you.

  • Using Selenium IDE with random values

    - by Toby Hede
    Is it possible to create Selenium tests using the Firefox plugin that use randomly generated values to help do regression tests? The full story: I would like to help my clients do acceptance testing by providing them with a suite of tests that use some smarts to create random (or at least pseudo-random) values for the database. One of the issues with my Selenium IDE tests at the moment is that they have predefined values - which makes some types of testing problematic.

  • UIButton stops responding after going into landscape mode - iPhone

    - by casey
    I've been trying different things the last few days and I've run out of ideas so I'm looking for help. The situation is that I'm displaying my in-app purchasing store view after the user clicks a button. Button pressed, view is displayed. The store shows fine. Inside this view, I have a few labels with descriptions of the product, and then below them I have the price and a Buy button which triggers the in-app purchase. Problem is when I rotate the phone to landscape, that Buy button no longer responds, weird. Works fine in portrait. The behavior in landscape when the I touch the button is nothing. It doesn't appear to press down and be selected or anything, just not responding to my touches. But then when I rotate back to portrait or even upside down portrait, it works fine. Here is the rough structure of my view in IB, all the rotating and layout is setup in IB. I set the autoresizing in IB so that everything looks ok in landscape and the Buy button expands horizontally a little bit. The only layout manipulation I do in my code is after loading, I set the content size of the scroll view. File Owner with view set to the scrollView / scrollView ----/ view --------/ label --------/ label --------/ label --------/ label --------/ label --------/ label --------/ label --------/ label --------/ uibutton (Buy) After orientation changes I printed out the userInteractionEnabled property of the scrollView and the button, and they were both TRUE at all orientations. Ideas? Or maybe some other way of displaying a buy button that won't be nonfunctional? I've already begun a branch that plays with a toolbar and placing the buy button there, but I can't seem to get the bar to stay in place while scrolling.

  • My image does not load on a jQuery fade in effect even though the div loads.

    - by Konstantin
    jQuery(document).ready(function() { if (useMSIE){ pngfixALL(); }; jQuery(div).show(data_fadeInEffect, 500);return false; // jQuery(div).animate({opacity:1}, 500, 'linear'); }); This is what I have for a fade in effect. When using animate(), the image in the div tag fades in fine. However, when I use show(), the div loads because I can click in that area, but the image itself doesn't load. Why is this happening? I have another area of the code where I click on an 'x' in the image and it fades out using hide(). This works fine.

  • what does < < mean in the shell

    - by stib
    when looping recursively through folders with files containing spaces the shell script I use is of this form, copied from the internet: while IFS= read -r -d $'\0' file; do dosomethingwith "$file" # do something with each file done < <(find /bar -name *foo* -print0) I think I understand he IFS bit, but I don't understand what the < < characters mean. Obviously there's some sort of piping going on here.. It's very hard to google "< <", you see. TIA -stib
