For each item in the view, I need to perform a long running operation, the result of which is a number. The way I would do this in native win32 is to create a worker thread for each item (naively; of course I won't create an unbounded number of threads) and then MsgWaitForMultipleObjects() on the array of thread handles. As each calculation finishes, the threads signal and the main UI thread wakes up and updates. In the mean time, we pump messages so the UI thread remains responsive. Can

Is there any tensorflow implementation for this? 回答1: R-CNN is using the following algorithm: Get region proposals for object detection (using selective search). For each region crop the area from the image and run it thorough a CNN which classify the object. There are more advanced algorithms that are built upon this like fast-R-CNN and faster R-CNN. fast-R-CNN: Run the entire image through the CNN For each region

My goal is to have one Google Analytics account and one web property for all 10 websites, a master profile (the default) that shows me metrics of all websites combined, and 10 individual profiles for each website to limit the view to just that website... as if it had its own Google Analytics account. After much research and reading, I think I determined that all I would need to do is add the following

It is either a curse or blessing, but often my brain tries to solve technical problems in my dreams. Sometimes it does. Like last night, my brain demanded to understand how to design an ECC algorithm (software program but possibly FPGA circuitry eventually) to implement the kind of ECC appropriate for disk drives. The kind of ECC appropriate for these devices appears to be "burst error detection". As I understand this, the reason disk drives have errors

I know there is a check box option in Jmeter CookieManager named " Clear Cookie on each Iteration ". But it clears the session on each iteration while I want to clear it at any time in the iteration. How can i do that in Jmeter? 回答1: Currently you cannot simply , particularly if you want to clear one particular cookie. You should raise an enhancement request at JMeter Bugzilla giving precision on what you want to do. I think a custom function would be a nice feature, see:

I want to do this in a way were I wouldn't have to change any of my existing queries or add an extra function like this suggests . I not that familiar with classes or the PDO class in particular, but could this be done? How would I go about this? I'm thinking extend query and execute and increment a stored variable each time they're called. 回答1: Extending PDO would be done like any other class. Would this suit your needs? The

I just try something out by using "lc variable" but it doesnt work. :-( My GNUPLOT script by now: set style data histograms set boxwidth 1 set grid set style histogram cluster gap 0 set style fill solid 1.0 border -1 set yrange [0:*] set xrange [0:*] set xtics

Either way you'll be iterating over the array; Array.map() just makes

You can do this without Javascript too. <meta http-equiv="refresh" content="2;url=http://path/to/the/page" /> 回答3: Quick and dirty: setTimeout ( function () { location . reload () }, 120000 ); Though I think there could possibly be a fancier
