With a JS mod for A Dark Room I am working on to increase my JS skills. Neither of these snippets are mine, and both are working perfectly.</p> <p>This is the code snippet to create the buttons:</p> <pre><code>build: function(buildBtn) { var thing = $(buildBtn).attr('buildThing'); if($SM.get('game.temperature.value') &lt;= Room.TempEnum.Cold.value) { Notifications.notify(Room, _("builder just shivers")); retu false; } </code></pre> <p>This snippet makes sure that buttons stay visible, but I would like to change it so that when a max value is met the button is hidden.</p> <pre><code>//show button if one has already been built if($SM.get('game.buildings["'+thing+'"]') &gt; 0){ Room.buttons[thing] = true; retu true; } </code></pre> http://stackoverflow.com/q/37444270 0 Yari http://stackoverflow.com/users/6382497 2016-05-25T17:44:43Z 2016-05-25T17:44:43Z <p>There is anybody that can help me with my App?

However, I have also seen vendors who reject webhook registration if ONLY subscription url is the same (meaning they require clients to update existing webhook rather than create a new one if the subscription url is the same). So the question is... Are there situations/use cases where different webhooks with same subscription url are required? In which case, 2nd implementation would not be sufficient... Thank you!</p> http://stackoverflow.com/q/37444265 0 Johy Engine http://stackoverflow.com/users/4181681 2016-05-25T17:44:27Z 2016-05-25T17:44:27Z <p>Uploaded a flash ad to my site via Google DFP, an SWF file with HTML5 and static images for fall backs.</p> <p>The client and account rep have raised issue that the ad loads in their browser with a play button, requiring the viewer to click play to start the animation.

However, I was surprised by the unexpected <code>end_time</code> of the period in the case of the <code>freq</code> argument having a multiplier (as in <code>freq='2D'</code>).</p> <pre><code>import pandas as pd p = pd.Period(1970, freq='2D') p # Period('1970-01-01', '2D') p.start_time # Timestamp('1970-01-01 00:00:00') p.end_time # Timestamp('1970-01-04 23:59:59.999999999') p.end_time - p.start_time # Timedelta('3 days 23:59:59.999999') </code></pre> <p>Why? That's 4 days, not 2.</p> <p>However:</p> <pre><code>p+1 # Period('1970-01-03', '2D') (p+1).start_time # Timestamp('1970-01-03 00:00:00') </code></pre> <p>So, <code>(p+1)</code> gives me the expected (a period starting 2 days after <code>p</code>'s start).</p> <p>But what's the deal with <code>end_time</code>?

So how could I do that? Can I change the variable to have read-and-write attributes, or maybe need a setter?</p> <p>My minimum working solution is:</p> <pre><code>from __future__ import print_function import datetime import os from atom.api import Atom, Unicode, Range, Typed, observe, Value, Bool class SimulationCase(Atom): startDateTime = datetime.datetime.strptime('05.03.2015-5','%d.%m.%Y-%H') currentDateTime = startDateTime endDateTime = startDateTime+ datetime.timedelta(days=int(5)) incrementTime = datetime.time(1,0,0) def main(): case = SimulationCase() print(case.currentDateTime) a = datetime.time(1,0,0) print(a) #This is where the problem occures, comment out the line under for a working solution. case.incrementTime = a if __name__ == '__main__': main() </code></pre> http://stackoverflow.com/q/16758353 2 Moolla http://stackoverflow.com/users/2017523 2013-05-26T10:32:29Z 2016-05-25T17:44:55Z <p>Is there a way to <code>slice</code> through a whole list while excluding a range of values or multiple range of values in the middle of the list?<br> For example: </p> <pre><code>list = [1,2,3,4,5,6,7,8,9,0] print list[......] #some code inside </code></pre> <p>I'd like the above code to print the list while excluding a range of values so the output would be: <code>[1,2,3,8,9,0]</code> or excluding multiple value ranges so the output would be: <code>[1,2,6,7,0]</code> by using the slice notation or any other simple method you can suggest.</p>
