i'm curious other developers when integrating twitter, facebook , other such feed content on site. make these requests , handle on client or server side? seems there number of jquery plugins out there handle type of simple integrations tend have sites, e.g 3 latest posts. previously, using php (twitter became more complicated integrate when switched openauth) content twitter, blogger etc, i'm wondering if there real need when can done javascript. obviously, if javascript isn't enabled feeds wouldn't display. interested hear people in situation! i tend hook directly feeds client-side code, unless i'm doing complicated, need additional validation or cache results of feed. the rationale if grab feeds on server, have 2 download data twice - once api server server, , once server - whereas grabbing directly api in client-side code results in single http request, should arguably load quicker. of course, if you've got lot of traffic, third-party se...

folks, i've been having trouble wf4 problem. i'm modeling batch engine/work scheduler after ron jacobs' demo in endpoint.tv webcast ( http://archive.msdn.microsoft.com/wf4batchjob ). in example, "work branch" counts inside while loop. sample, send message workflow called sampleengine.xamlx counting. every count, workflow calls parent (jobscheduler.xamlx) , reports progress completed. works , have working - can schedule job , watch progress both in appfabric dashboard , calling queryprogress (a send/receive pair in scheduler workflow). the problem when iireset simulate server failure or other problem, workflows (sampleengine.xamlx , jobscheduler.xamlx) both come online , show "in progress". problem neither of them track more events - seem stalled somewhere. furthermore, neither of them respond service messages in same way see wf services respond when there's no receive activity scheduled workflow's current state. i've added persist a...

i have treeview allows users select elements of hierarchical data checking or un-checking each item's checkbox. disable box on nodes have children using checkbox hiding technique question , so: ☑ node 1 ☐ node 2 • node 3 ☑ node 3.1 ☑ node 3.2 • node 4 ☐ node 4.1 ☑ node 4.2 but better solution use tri-state check boxes parent nodes, this: ☑ node 1 ☐ node 2 ☑ node 3 ☑ node 3.1 ☑ node 3.2 ☒ node 4 ☐ node 4.1 ☑ node 4.2 since functionality available in win32, question how without drawing boxes myself (e.g., user-drawn control or using image list ). not familiar win32 api @ all; how 1 extend technique linked above enable tri-state checboxes on managed treeview control? have taken @ this ? seems job. might bit dated, (looks article 2004), i'm sure same principles can extended whatever need do.

i'm using nsimageview display animated gif around 80 frames, each frame being 20ms long. nsimageview can display gif animation right 'out of box', problem needs cpu, around 10% continuously (on core i5 proc). instruments shows spends lot of cpu time decoding gif. to make more efficient, have tried following without success: putting frames inside qtmovie , playing (uses 4% process , 15% qtkitserver process plays movie) drawing directly view cgcontextdrawimage (~5% cpu usage) - didn't export gif's frames, created cgimageref 30x30px .png had lying around. i don't know else try. subclassing nsimageview , somehow caching images sounds idea but, alas, i'm beginner in cocoa... ideas appreciated. thanks! check out this article raphael schaad. that's performant gets without super complicated. github repo looks it's ios don't think it'll hard port.
