  • Can I use Sikuli as an Jython library in my project?

    - by Yinan
    Sikuli is really cool, but it's working in its buildin Jython environment, the Sikuli IDE. So I m wondering is it possible to import Sikuli as an external library to my Jython library? I saw from Sikuli's website that they have this Python module which provides all Sikuli actions like click and type. Here is the link: http://sikuli.org/documentation.shtml#doc/pythondoc-python.edu.mit.csail.uid.Sikuli.html I have tried importing the skiuli-script.jar and add the skiuli-script/Lib to the PYTHONPATH. Then in my spike.py script, I try to do this: import python.edu.mit.csail.uid.Sikuli capture() #enter to screen capture mode then when execute the script, I got this error: java.lang.UnsatisfiedLinkError: java.lang.UnsatisfiedLinkError: /eclipse_3.4.2/workspace/Jython/src/tmplib/libVDictProxy.jnilib: no suitable image found. Did find: /eclipse_3.4.2/workspace/Jython/src/tmplib/libVDictProxy.jnilib: no matching architecture in universal wrapper I m using Jython 2.2.1 and Mac 10.6.2 (32-bit mode). I have also set to use 32-bit mode first in Java Preference.

  • Is it possible to drag windows between workspaces when using Compiz?

    - by Mike Stone
    When I used Metacity, I could drag windows between workspaces using the small icon view of my workspaces. I recently started using Compiz for all the cool desktop effects, however this drag and drop feature isn't working. I use the cube effect for switching workspaces, but I noticed the wall effect doesn't allow it either. Is this just a missing feature from Compiz or is there a setting somewhere that I can enable it? I know that I can enable dragging windows across edges to the next workspace, and the expose feature to drag windows between workspaces. However, the drag and drop on the icon view is really powerful, and I would love to have it back along with all the great Compiz special effects.

  • C: How come an array's address is equal to its value?

    - by Alexandre
    In the following bit of code, pointer values and pointer addresses differ as expected. But array values and addresses don't! How can this be? Output my_array = 0022FF00 &my_array = 0022FF00 pointer_to_array = 0022FF00 &pointer_to_array = 0022FEFC ... #include <stdio.h> int main() { char my_array[100] = "some cool string"; printf("my_array = %p\n", my_array); printf("&my_array = %p\n", &my_array); char *pointer_to_array = my_array; printf("pointer_to_array = %p\n", pointer_to_array); printf("&pointer_to_array = %p\n", &pointer_to_array); printf("Press ENTER to continue...\n"); getchar(); return 0; }

  • Is there any reasons to prefer SparkViewEngine over XSLT (or vice versa) for a standalone email gene

    - by Stephane
    I have a service that receives an object containing all the data needed to build a newsletter. I need to be able to generate the email using different templates. I don't want to involve the whole ASP.NET stack for that, so I want a separate templating engine. Reading a lot of opinions, I have found that XSLT was not getting very much love when it comes to templating engines. Why? SparkViewEngine is a "new cool toy", but it seems mature enough considering the number of projects that have been built with it. What do you think? Did you used those 2 engines? in which situation, and what strength/pain did you enjoy/endure

  • How do you use kate? Tips/Tricks/Workflow

    - by Roman A. Taycher
    We all seen a bunch of these? Mostly for IDE's but also for vim and emacs. Kate is (only) a text editor (an awesome one) but it has a ton of options plus a number of plugins, so its hard to know all of it well. How do use the Kate text editor? Please share your workflow and help me and others learn some of the cool tricks you use. I'll start I use the built in terminal a lot opening files quickly, and using it as an enhanced haskell repl with ghci (since ghci doesn't allow you all to just put in all kinds of haskell code). Also use split views to quickly compare files (especially different versions of the same file). Also the auto-complete maybe simple(more use for saving typing time then remembering functions) but it works really well for that. Also if You highlight something and hit a start [/{/( it puts it in between brackets rather then replacing it with a bracket(why the hell do a lot of IDEs not have this feature).

  • Does performance even matter anymore? [closed]

    - by Jeff Dahmer
    The performance differences between C/C++ and C# are astounding. An ASP.NET page loads in 1/8 the time that a PHP script does haha.... WPF, aka " The Future ", (you know it will be, all the companies are gonna want cool looking desktop apps, don't kid yourself.) And it has huge performance hits just to start up. We've let Microsoft make us as developers lazy! Why do I hate this, it's such a good thing? Are we at a point in time where the majority of computers can handle this kinda crap? I remember when performance used to matter. Anyways, I'm writing a .NET library and ever since I found out LINQ is slower than traditional delegates which is slower than the normal procedural code... well it's a guilty evil I feel for every LINQ query I write, because they are so beautiful. Am I just too much of a performance stickler? Or just too big of a nerd?

  • iPad title bars. Navbars or toolbars?

    - by Squeegy
    I see a bunch of apps for iPad with really cool title bars. These seem to be a combination of a navigation bar and a toolbar. They usually have a back button and a title as well as men other buttons. And a navbar only supports a left item, a right item and and title view. And the toolbar does not really support back buttons or titles. So how do I implement these rich navbars with many buttons on my UINavigationController driven application?

  • What would be the disadvantages/risks of using AF_UNSPEC?

    - by Kiril Kirov
    From Beej's Guide to Network programming You can force it to use IPv4 or IPv6 in the ai_family field, or leave it as AF_UNSPEC to use whatever. This is cool because your code can be IP version-agnostic. As the title says - what would be the disadvantages (or risks, if any) of always using AF_UNSPEC, instead of specifying IPv4 or IPv6? Or it's only for one reason - if the version is specified, this will guarantee that this and only this version is supported? A little background - I think about adding support for IPv6 in client-server (C++) applications and both versions should be supported. So I wondered if it's fine to use AF_UNSPEC or it's better to "recognize" the address from the string and use AF_INET6 or AF_INET, depending on the address.

  • jQuery and CodeIgniter AJAX with JSON not working

    - by thedp
    Hello, I trying to make my first AJAX with JSON call using jQuery and CodeIgniter. But for some weird reason it's not working. The jQuery code: var item = "COOL!"; $.post("http://192.168.8.138/index.php/main/test", { "item" : item }, function(data){ alert(data.result); }, "json"); The CodeIgniter code: <?php class main extends Controller { function test() { $item = trim($this->input->post('item')); $array = array('result' => $item); echo json_encode($array); } } ?> I tried to access the http://192.168.8.138/index.php/main/test page manually and it seems to be working, I got: {"result":""} I also tried to use Firebug to see XMLHttpRequest but saw nothing. I have no idea what am I doing wrong... Need help really badly. Thank you.

  • Log4cxx sample program and steps to compile

    - by Jake
    Hi guys Hoping someone can help out.. I've been scouring the net for a simple how-to to get a good log4cxx program working, with steps on setting up the libraries, dependants, directives, library paths etc etc.. as of yet i've found a lot of valuable but disjointed information.. trying to pull it all together has been a bit of a nightmare, so i'm reaching out and wondering if any kind soul knows of, or could put together a simple how-to, to get a standard win32 console app running with either static or dynamically linked release mode log4cxx.. I have win32 binary releases of the libraries, and thanks to a very cool dude from "Must a blog have a name" I have a win32 project which can build log4cxx.. i just cant bloody use it :) It would be really helpful to me, and probably to others, to be able to refer to something like this and not 20 different pages, with different lists of libraries needed to download and install.. :) Here's hoping Thanks guys J

  • Position of least significant bit that is set

    - by peterchen
    I am looking for an efficient way to determine the position of the least significant bit that is set in an integer, e.g. for 0x0FF0 it would be 4. A trivial implementation is this: unsigned GetLowestBitPos(unsigned value) { assert(value != 0); // handled separately unsigned pos = 0; while (!(value & 1)) { value >>= 1; ++pos; } return pos; } Any ideas how to squeeze some cycles out of it? (Note: this question is for people that enjoy such things, not for people to tell me xyzoptimization is evil.) [edit] Thanks everyone for the ideas! I've learnt a few other things, too. Cool!

  • Bad temperature sensors on Foxconn motherboard?

    - by Gawain
    I have a system with a Foxconn V400 series motherboard and AMD Athlon 3000+ processor. Ever since I got it a few years ago the fans (particularly the CPU fan) have been really loud. So recently I installed SpeedFan to see why they were running so fast. SpeedFan reported the CPU temperature to be 32C, and one motherboard sensor at about 26C. But the other two motherboard sensors were reporting 78C and 64C respectively. Naturally the fans were both maxed out because of this, with the CPU fan at 5800rpm and the case fan at 2400rpm. I opened the case and everything inside was literally cool to the touch, with the exception of the CPU heatsink which was slightly warm, but nowhere near 78C. It seems like the temperature sensors are either defective or being read incorrectly. Is there some way I can decrease my fan noise without risking damage to my processor? Some way to ignore those two temp sensors? Any help would be greatly appreciated.

  • How to protect web site against hackers?

    - by Adi barda
    Hi Guys, Like everyone of us, I have my own dreams about developing the next cool product that will be adopted by many users and become industry standard. Surprisingly, I find that the most challenging task is to keep my website up & running. My site is being hacked again and again no matter what I do - I blocked the FTP connections, changed the Joomla (CMS) database table names, installed all latest patches and what not. The web site supports the product (over 1800 users now...) by generating licenses, support forums, documentation, galleries etc. The product which is a winforms application cannot be marketed without this web site. My question: Do you have any innovative idea about securing joomla based web sites or what is the best secured web hosting you know. currently i'm hosting my site at ixwebhosting and i like them very much but obviously i can't do any serious marketing being hacked over and over again Thank you very much, Adi Barda

  • Python Closures Example Code

    - by user336527
    I am learning Python using "Dive Into Python 3" book. I like it, but I don't understand the example used to introduce Closures in Section 6.5. I mean, I see how it works, and I think it's really cool. But I don't see any real benefit: it seems to me the same result could be achieved by simply reading in the rules file line by line in a loop, and doing search / replace for each line read. Could someone help me to: either understand why using closures in this example improves the code (e.g., easier to maintain, extend, reuse, or debug?) or suggest a source of some other real-life code examples where closures really shine? Thank you!

  • What to implement today to help yourself fixing bugs in the future?

    - by Heinrich Ulbricht
    Assume you are in the process of developing some really cool software. It will be deployed to a lot of customers. They will need this software and they will use it in time-critical situations. So if something goes wrong they will call (you). And you or your team will be the ones who have to resolve the issue. Fast. You know out of experience this will happen. Now if you could decide what to implement to aid your future self - what would that be?

  • cached schwartzian transform

    - by davidk01
    I'm going through "Intermediate Perl" and it's pretty cool. I just finished the section on "The Schwartzian Transform" and after it sunk in I started to wonder why the transform doesn't use a cache. In lists that have several repeated values the transform recomputes the value for each one so I thought why not use a hash to cache results. Here' some code: # a place to keep our results my %cache; # the transformation we are interested in sub foo { # expensive operations } # some data my @unsorted_list = ....; # sorting with the help of the cache my @sorted_list = sort { ($cache{$a} or $cache{$a} = &foo($a)) <=> ($cache{$b} or $cache{$b} = &foo($b)) } @unsorted_list; Am I missing something? Why isn't the cached version of the Schwartzian transform listed in books and in general just better circulated because on first glance I think the cached version should be more efficient?

  • ASP.NET MVC IoC usability

    - by Andrew Florko
    Hello everybody, How often do you use IoC for controllers/DAL in real projects? IoC allows to abstract application from concrete implementation with additional layer of interfaces that should be implemented. But how often concrete implementation changes? Should we really have to do job twice adding method to interface then the implementation if implementation hardly will ever be changed? I took part in about 10 asp.net projects and DAL (ORM-like and not) was never rewritten completely. Watching lots of videos I clearly understand that IoC "is cool" and the really nice way to program, but does it really needed?

  • cmake: Target-specific preprocessor definitions for CUDA targets seems not to work

    - by Nils
    I'm using cmake 2.8.1 on Mac OSX 10.6 with CUDA 3.0. So I added a CUDA target which needs BLOCK_SIZE set to some number in order to compile. cuda_add_executable(SimpleTestsCUDA SimpleTests.cu BlockMatrix.cpp Matrix.cpp ) set_target_properties(SimpleTestsCUDA PROPERTIES COMPILE_FLAGS -DBLOCK_SIZE=3) When running make VERBOSE=1 I noticed that nvcc is invoked w/o -DBLOCK_SIZE=3, which results in an error, because BLOCK_SIZE is used in the code, but defined nowhere. Now I used the same definition for a CPU target (using add_executable(...)) and there it worked. So now the questions: How do I figure out what cmake does with the set_target_properties line if it points to a CUDA target? Googling around didn't help so far and a workaround would be cool..

  • I would like to build a Java Web Application. What's the quickest start?

    - by Vish
    I am a reasonably competent programmer, with about 11 years experience. I particularly like Ruby/Rails and ActionScript. And Java is not too hard. I'd like to develop a web application in Java in order to leverage things like BlazeDS and learn some new tricks with regard to JBoss and the whole Java App thing. But I'm having trouble - and confused - looking for a smooth start. I don't want to use Grails, thanks, I want to use Pure Java, with whatever Framework you can think of. Spring, Hibernate, lalala, it's cool. Where do I start?

  • Cropping image with ImageScience

    - by fl00r
    ImageScience is cool and light. I am using it in my sinatra app. But I can't understand how can I crop image with not square form and how can I make thumbnail with two dimensions. As I found on ImageScience site: ImageScience.with_image(file) do |img| img.cropped_thumbnail(100) do |thumb| thumb.save "#{file}_cropped.png" end img.thumbnail(100) do |thumb| thumb.save "#{file}_thumb.png" end img.resize(100, 150) do |img2| img2.save "#{file}_resize.png" end end I can crop thumb and resize thumb only with ONE dimension but I want to use two, as in RMagick. For example I want to crop 100x200px box from image, or I want to make thumbnail with width or height not bigger then 300 (width) or 500 (height) pixels.

  • JavaScript distributed computing project

    - by Ben L.
    I made a website that does absolutely nothing, and I've proven to myself that people like to stay there - I've already logged 11+ hours worth of cumulative time on the page. My question is whether it would be possible (or practical) to use the website as a distributed computing site. My first impulse was to find out if there were any JavaScript distributed computing projects already active, so that I could put a piece of code on the page and be done. Unfortunately, all I could find was a big list of websites that thought it might be a cool idea. I'm thinking that I might want to start with something like integer factorization - in this case, RSA numbers. It would be easy for the server to check if an answer was correct (simply test for modulus equals zero), and also easy to implement. Is my idea feasible? Is there already a project out there that I can use?

  • Should I unit test my JavaScript?

    - by Joseph Silvashy
    I'm curious to if it would be valuable, I'd like to start using QUnit, but I really don't know where to get started. Actually I'm not going to lie, I'm new to testing in general, not just with JS. I'm hoping to get some tips to how I would start using unit testing with an app that already has a large amount of JavaScript (ok so about 500 lines, not huge, be enough to make me wonder if I have regression that goes unnoticed). How would you recommend getting started and Where would I write my tests? (for example its rails app, where is a logical place to have my JS tests, it would be cool if they could go in the /test directory but it's outside the public directory and thus not possible... err is it?)
