  • `var = something rescue nil` behaviour

    - by JP
    In ruby you can throw a rescue at the end of an assignment to catch any errors that might come up. I have a function (below: a_function_that_may_fail) where it's convenient to let it throw an error if certain conditions aren't met. The following code works well post = {} # Other Hash stuff post['Caption'] = a_function_that_may_fail rescue nil However I'd like to have post['Caption'] not even set if the function fails. I know I can do: begin post['Caption'] = a_function_that_may_fail recsue end but that feels a little excessive - is there a simpler solution?

  • Alternative to before </body> tag inline Javascript

    - by Mohammad
    I know inline Javascript is frowned upon and with the new on-the-fly Javascript compressors that check for idle/unused function usage and omit the unused code, it seems good practice to have all your Javascript in an external file. My question is, in situations like FOUC (flash of unstyled content) which usually require little snippets of code right before the closing </body> tag, is there a JQuery resolution that would serve the same purpose, but from a remote Javascript file linked in the <head> of the document?

  • Good book on Castle Project?

    - by David
    Does anyone know of a good book on the Castle Project? I'm interested in learning more about any of the Castle projects (ActiveRecord, MonoRail, Windsor, anything!) and searches for Castle on Amazon are a little frustrating with the need to weed out all the fiction and nonsense.

  • Django admin fails when using includes in urlpatterns

    - by zenWeasel
    I am trying to refactor out my application a little bit to keep it from getting too unwieldily. So I started to move some of the urlpatterns out to sub files as the documentation proposes. Besides that fact that it just doesn't seem to be working (the items are not being rerouted) but when I go to the admin, it says that 'urlpatterns has not been defined'. The urls.py I have at the root of my application is: if settings.ENABLE_SSL: urlpatterns = patterns('', (r'^checkout/orderform/onepage/(\w*)/$','checkout.views.one_page_orderform',{'SSL':True},'commerce.checkout.views.single_product_orderform'), ) else: urlpatterns = patterns('', (r'^checkout/orderform/onepage/(\w*)/$','commerce.checkout.views.single_product_orderform'), ) urlpatterns+= patterns('', (r'^$', 'alchemysites.views.route_to_home'), (r'^%s/' % settings.DAJAXICE_MEDIA_PREFIX, include('dajaxice.urls')), (r'^/checkout/', include('commerce.urls')), (r'^/offers',include('commerce.urls')), (r'^/order/',include('commerce.urls')), (r'^admin/', include(admin.site.urls)), (r'^accounts/login/$', login), (r'^accounts/logout/$', logout), (r'^(?P<path>.*)/$','alchemysites.views.get_path'), (r'^static/(?P<path>.*)$', 'django.views.static.serve', {'document_root':settings.MEDIA_ROOT}), The urls I have moved out so far are the checkout/offers/order which are all subapps of 'commerce' where the urls.py for the apps are so to be clear. /urls.py in questions (included here) /commerce/urls.py where the urls.py I want to include is: order_info = { 'queryset': Order.objects.all(), } urlpatterns+= patterns('', (r'^offers/$','offers.views.start_offers'), (r'^offers/([a-zA-Z0-9-]*)/order/(\d*)/add/([a-zA-Z0-9-]*)/(\w*)/next/([a-zA-Z0-9-)/$','offers.views.show_offer'), (r'^reports/orders/$', list_detail.object_list,order_info), ) and the applications offers lies under commerce. And so the additional problem is that admin will not work at all, so I'm thinking because I killed it somewhere with my includes. Things I have checked for: Is the urlpatterns variable accidentally getting reset somewhere (i.e. urlpatterns = patterns, instead of urlpatterns+= patterns) Are the patterns in commerce.urls valid (yes, when moved back to root they work). So from there I am stumped. I can move everything back into the root, but was trying to get a little decoupled, not just for theoretical reason but for some short terms ones. Lastly if I enter www.domainname/checkout/orderform/onepage/xxxjsd I get the correct page. However, entering www.domainname/checkout/ gets handled by the alchemysites.views.get_path. If not the answer (because this is pretty darn specific), then is there a good way for troubleshoot urls.py? It seems to just be trial and error. Seems there should be some sort of parser that will tell you what your urlpatterns will do.

  • How stable are Cisco IOS OIDs for querying data with SNMP across different model devices?

    - by Daniel Papasian
    I'm querying a bunch of information from cisco switches using SNMP. For instance, I'm pulling information on neighbors detected using CDP by doing an snmpwalk on .1.3.6.1.4.1.9.9.23 Can I use this OID across different cisco models? What pitfalls should I be aware of? To me, I'm a little uneasy about using numeric OIDs - it seems like I should be using a MIB database or something and using the named OIDs, in order to gain cross-device compatibility, but perhaps I'm just imagining the need for that.

  • Can I use CodeRush Xpress in Visual Studio 2010?

    - by Tomas Lycken
    I've installed the Beta 1 of Visual Studio 2010, and started working a little. Even though I haven't been using CodeRush Xpress for long in Visual Studio 2008, I immediately started missing some of the neat functionality. Is there any way to install CodeRush Xpress on Visual Studio 2010, even though it's only the Beta yet?

  • Are there programs that iteratively write new programs?

    - by chris
    For about a year I have been thinking about writing a program that writes programs. This would primarily be a playful exercise that might teach me some new concepts. My inspiration came from negentropy and the ability for order to emerge from chaos and new chaos to arise out of order in infinite succession. To be more specific, the program would start by writing a short random string. If the string compiles the programs will log it for later comparison. If the string does not compile the program will try to rewrite it until it does compile. As more strings (mini 'useless' programs) are logged they can be parsed for similarities and used to generate a grammar. This grammar can then be drawn on to write more strings that have a higher probability of compilation than purely random strings. This is obviously more than a little silly, but I thought it would be fun to try and grow a program like this. And as a byproduct I get a bunch of unique programs that I can visualize and call art. I'll probably write this in Ruby due to its simple syntax and dynamic compilation and then I will visualize in processing using ruby-processing. What I would like to know is: Is there a name for this type of programming? What currently exists in this field? Who are the primary contributors? BONUS! - In what ways can I procedurally assign value to output programs beyond compiles(y/n)? I may want to extend the functionality of this program to generate a program based on parameters, but I want the program to define those parameters through running the programs that compile and assigning meaning to the programs output. This question is probably more involved than reasonable for a bonus, but if you can think of a simple way to get something like this done in less than 23 lines or one hyperlink, please toss it into your response. I know that this is not quite meta-programming and from the little I know of AI and generative algorithms they are usually more goal oriented than what I am thinking. What would be optimal is a program that continually rewrites and improves itself so I don't have to ^_^

  • Does anyone here uses PHP-GTK? Is there a better alternative?

    - by levhita
    I had made some questions regarding php-gtk(there are only 4 php-gtk tagged questions and 3 are mine) and I end up answering myself because no one answer them. I know is a strange language selection but I was attracted to it because it runs on several OS's and the fact that I can reuse some of my code (also the apps end up looking good and I can make little installers in NSIS that just rocks). Is there a better alternative, that is free(as freedom) and can run on several platforms?

  • HTML5 enabled browser for Windows Mobile 6

    - by Herberth Amaral
    I did some research on Google but I couldn't find any HTML5 browser for Windows Mobile 6. The main resource I'm looking for in HTML5 is WebDatabase and/or localStorage. With a little research I found Iris (http://www.freewarepocketpc.net/ppc-download-iris-browser.html), a Webkit based browser with some HTML5 features, but localStorage and Web Database doesn't work on it. Does anyone know any browser with storage capability for Windows Mobile 6?

  • How do I force a jQuery click event to proceed any control click event on ASP.Net page

    - by Cen
    I've found posts about making a click event with jQuery for a button, however I need a little more then that. When any postback occurs on a page, I need to fire off a jQuery click event. Based on a condition, I want to continue processing (including running the server-side event code after the jQuery code), or, perform a redirect. I'm not quite sure how to go about this. Your help is appreciated!

  • SVN Tree Conflict Errors

    - by John
    I seem to see such errors quite often in our SVN 1.6 repo. We got these quite a lot while we used to just work on /trunk so I don't think it's due to merge/branching confusion. It seems that a cleup and marking the conflict resolved always works, but it's a little concerning to see errors in your version control system when you're just adding/updating/deleting files. What causes it?

  • How to run Cg vertex/fragment shader on CPU?

    - by Andy
    Hi all, I'm playing about with some vertex and fragment shaders using Cg on my little netbook (running Linux). Clearly I'm going to frequently hit resource limits for my graphics controller, so was wondering if there's a nice way to run the shaders on the CPU, just to test them. Something like D3D's refrast... TIA Andy

  • Capture link clickthrough events from Javascript

    - by Silver Dragon
    In order to track the overall user clickstream, I'd like to fire a javascript event, if the user right-clicks, and select "Open in new Tab" (or middle-clicks in most browsers) on a link. Most of these links are linking outside of my site, and I'd like to interfere with overall browser experience (such as: status bar, etc) as little as possible. What options are there to solve this?
