  • Get Auto Increment value with MySQL query

    - by James Simpson
    I currently have a database with over 6 million rows and growing. I currently do SELECT COUNT(id) FROM table; in order to display the number to my users, but the database is getting large and I have no need to store all of those rows except to be able to show the number. Is there a way to select the auto_increment value to display so that I can clear out most of the rows in the database? Using LAST_INSERT_ID() doesn't seem to work.

  • EADDRNOTAVAIL when binding 127.0.0.1 on localhost?

    - by Jonas Byström
    I'm getting errno==49 (EADDRNOTAVAIL) when trying to UDP-bind() to 127.0.0.1:47346 running Mac OS X on a G5 (big endian PowerPC). Is there something preventing me from doing so? I've tried other addresses and ports (192.168.1.2 and port 47346) but with no success. Here's a gdb printout of my sockaddr_in: $1 = { sin_len = 0 '\0', sin_family = 2 '\002', sin_port = 47346, sin_addr = { s_addr = 3232235778 }, sin_zero = "???\000\000??" }

  • flash's "useHandCursor = true" not working for Chrome on Mac

    - by fucrate
    I'm developing a flash game using the default SimpleButton object for my buttons and the hand cursor is working just fine on PC Chrome and Firefox and Safari for Mac, but Chrome on Mac is not letting me swap the default cursor for the hand cursor. I've even set useHandCursor to true for every button I add a click event to and am still getting nothing. We've got no other rollover events, so it's important that the cursor switch. Anyone else run into this and have a lil-fixy / workaround?

  • 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.

    I've spent the last year learning and using Java in university but we didn't do much (read: anything) in terms of Threading. We do some next year but I'm hopeful I'll be able to get a head start over the summer. What are the best resources for learning about and getting to grips with Threading?

  • Visual studio 2010 Errors out on starting "-832" is not a valid value for property "width"

    - by Solmead
    My Visual Studio 2010 was working fine this morning (I run in in XP sP3 under Paralles) I restarted the entire laptop and I started getting this error. I even uninstalled VS2010, deleted the Visual Studio 20010 directory on the My Documents area and reinstalled it, and it is still giving me that error every time I try to start it. I'm not sure if stackoverflow is the place to ask it, but I am at my wits end trying to get this running again (trying to avoid rebuilding the entire Virtual PC) Does anyone know how to fix this?
