Time of occurence of a Google calendar recurring event (Python API)
my problem is kind of the same, but the solution is not good for me, because I don't need all other recurrences of that same event, I need only one nearest to today. I don't think its smart to use singleEvents=true in my case because of traffic and processing of unnecessary data. so the only choice what i'm left with is try to find nearest event by recurrence rule. or am I missing something? maybe somebody have solved this problem?
Here is what I am doing using the c# api :
evtQuery.SingleEvents = true;
evtQuery.SortOrder = CalendarSortOrder.ascending;
evtQuery.ExtraParameters = "orderby=starttime";
evtQuery.StartTime = start;
evtQuery.EndTime = end;
evtFeed = calSvc.Query(evtQuery);
start and end are set with +-1 day from now.
Then, when browsing evtFeed, if I don't get what I am searching, I am doing a new request with start and end set with +-5 Days.

I asked this question in the Storm user group and haven't gotten a response yet, so I decided to ask it here. I've found the code, and many references to how the the taskIndex is calculated but when I try using the following I don't get the same result as my Storm topology. I've also seen more than one posting where others report the same.
Here's the question:
Hello,
I’ve tried to use the information below to generate the hash, mod it, and in turn, calculate the correct consuming destination task index, but without success. I’ve scoured the Internet to find an example of a hand calculation of this nature and have turned up empty. I must be missing something in my hand calc, so I’m hoping someone on the list can help me out.
I have field grouped as follows:
.fieldsGrouping(EXAMPLE_BOLT, EXAMPLE_BOLT_STREAM, new Fields(TopologyConstants.EXAMPLE_FIELD_GROUPING_ID))
My EXAMPLE_BOLT emits as shown here:
collector.emit(TopologyConstants.EXAMPLE_BOLT_STREAM, new Values(EXAMPLE_FIELD_GROUPING_ID_VALUE, EXAMPLE_DATA_INSTANCE));
I perform the calculation as follows:
int numberOfConsumingTasks = x;
Integer EXAMPLE_FIELD_GROUPING_ID_VALUE = y;
ArrayList alist = new ArrayList();
alist.add(EXAMPLE_FIELD_GROUPING_ID_VALUE);
int hashCode = Arrays.deepHashCode(alist.toArray());
int targetTaskIndex = Math.abs(hashCode) % numberOfConsumingTasks;
The resulting targetTaskIndex value from this calculation does not match the value produced by Storm, when I use real values from my topology.
Can someone tell me what I’m doing wrong?
Thanks,
Aubrey
I have an Observable that is based on some events and at some point does some expensive computation. I would like to render the results from that Observable in multiple different places. If I naively subscribe to this Observable in two places I will end up doing the expensive computation twice. Here is a code snippet to drive my point home:
var s = new rx.Subject();
var o = s.map(x => { console.log('expensive computation'); return x });
o.subscribe(x => console.log('1: ' + x));
o.subscribe(x => console.log('2: ' + x));
s.next(42);
The output is:
expensive computation
1: 42
expensive computation
2: 42
I would like to perform the expensive computation in the map only once. share accomplishes this, but it makes it so late-arriving subscribers do not get the current value to render. In previous RxJS versions, shareValue allowed late-arriving subscribers to get the current value. However, it appears that this was renamed to shareBehavior in RxJS 5 and then removed altogether:
https://github.com/ReactiveX/rxjs/pull/588
https://github.com/ReactiveX/rxjs/pull/712
There is a long discussion in this issue where it was decided that they would 'Remove shareBehavior and shareReplay to prevent user confusion.' I don't understand what the potential for confusion was (so maybe that means I am one of the users saved by this decision?).
publishBehavior also looks promising but I don't fully understand publish and it seems like it adds more complexity than I need or want.
Anyway, I would like to know if there is a recommended way to accomplish this in RxJS 5. The migration doc doesn't provide any recommendations.
After some more research I've found that the behavior I've described can be implemented with
.publishBehavior(startValue).refCount().
This discovery is based on the fact that share() is an alias for publish().refCount(). I still don't fully understand publish() but this seems to have the desired effect in practice.
Similar is cache(1) (which is an alias for publishReplay(1).refCount()). It has a similar effect as publishBehavior(defaultValue).refCount() except that it does not start with a default value. So if no items have been emitted, new subscribers will not immediately receive a value.
I am using Ember.js to build a website for my company.
The problem I am having is that the initial load time of the page is around 10 seconds.
I cant give you the profiling data from chrome because I can't get them out of work.
However what I noticed when looking at them is that there is a function called "Get" which takes in total around 8.5 seconds. I realize this is probably just many uses of Ember.Get(), but still this is just the initial page load.
I don't know if this is normal or not but it's extremely unpleasant. Is there something I can do about this?
Thanks, Jason
try using a production release (the minified version of ember.js), it uses a significantly faster get.
Are you rendering some very large lists? If so look into using List View.
If you have a ton of fields being bound that don't ever change modify them to be unbound.
{{unbound someField}}
If you are having some weird issue where a template is taking a long time, yet you aren't sure which one it is, you can add some timestamp logging to the beginning of your templates to track down the culprit. At the bottom I whipped up a quick helper. In your template you could use it like so. It will print out a timestamp with that data point passed in.
{{logTime this}}
{{logTime name}}
Ember.Handlebars.helper('logTime', function(someField){
var d = new Date,
timestamp = d.toTimeString().replace(/.*(\d{2}:\d{2}:\d{2}).*/, "$1") + "." + d.getMilliseconds();
console.log(timestamp + " - " + text);
return "";
});
I building a custom user control in asp.net where the user can enter in a date. I am already using a JQuery function that puts in a date mask in the format of dd/mm/yyyy, but I am unable to find another JQuery function(s) or one that combines all my needs.
What I am also looking for is:
1) To validate whether the date is really a date, i.e. not 31/13/2010 or anything along those lines.
2) Where I can check to see whether a date is in the past or in future based upon a configuration entry in the application.
Can anyone help me, please?
This is just off the top of my head, but you could use JavaScript's Date object http://www.w3schools.com/jsref/jsref_obj_date.asp
1) You could use one of the following
var d = new Date(dateString);
var d = new Date(year, month, day, hours, minutes, seconds, milliseconds);
Then verify that the date components are the same as entered. If you set the month to 50, it will take the year, and go 50 months forward... which seems odd, but... Just have to verify the information is what you entered. The months start at 0 for January, so when checking, be aware of that.
2) There's probably a lot of ways to do this check, but a quick thought on it is
var t = d.getTime() - new Date().getTime();
If t is positive, it's in the future, if it's negative it's in the past.
The new Date() creates a date object with the current time.
You could also use the jQuery UI DatePicker. http://jqueryui.com/demos/datepicker/
I haven't checking into the exact functionality it has that might fit your requirement, but it is another resource to check into.

I'm trying to use the NDFD (National Digital Forecast Database) to get current temperature and relative humidity given a Lat and Long using their REST based service.
The issue at hand:
I can't match the 'current observation data' WITH the 'results' I get back from the REST-service.
The setup:
Location:
* Apple (1-infinite loop, Cupertino, California)
* Lat = 37.33; Lon = -122.03
If I issue the following REST-call:
http://www.weather.gov/forecasts/xml/sample_products/browser_interface/ndfdXMLclient.php?lat=37.33&lon=-122.03&product=time-series&begin=2009-06-21T17:12:35&end=2009-06-21T17:12:35&appt=appt&rh=rh&temp_r=temp_r&temp=temp
Note 1: I'm passing the begin and end time in UTC. They're the same because I'm
looking for just a single-point-in-time: the latest observed
temp and relative humidity.
AND, then compare it to what is the closet reporting stations (San Jose International Airport, CA - KSJC - 37.37N 121.93W) # http://www.weather.gov/xml/current_obs/KSJC.xml
** I can never get them to MATCH. **
Note 2: The nearest reporting station is return back from the REST call
as well, so I know I'm comparing Location apples to Location apples.
I've had two ideas:
1: I'm doing something wrong with how I'm passing in the begin/end times into the REST call...
2: You can't get 'current observed data' the way I'm trying to...
Lastly:
I've found a solution using outoftime's NOAA ruby lib , [it parses an observation stations YAML file to find the nearest one given Lat/Lng then goes directly to that station via its identifier i.e. http://www.weather.gov/xml/current_obs/KSJC.xml].... but it just feels like I may be missing something obvious here and would like to use the REST-based interface ;)
Any help or pointers would be appreciated!
Thanks!
It looks like the service you are calling isn't for current data. Judging by the URL and the XML results it seems to be for forecasts. You can also put in future dates to get future forecast data. It expects the dates to be in the -0700 time zone according to the response. I'm not sure which service you should be calling to get the data you want though.
I know that this is an old question, but this is what I'm using to get current weather conditions: http://forecast.weather.gov/MapClick.php?lat=43.09110&lon=-79.0162&unit=0&lg=english&FcstType=dwml
Found this api/link yesterday. Its still developmental (operation-mode="developmental"):
http://forecast.weather.gov/MapClick.php?lat=37.33&lon=-122.03&FcstType=dwml
If you want the "current" observation, you use the XML here:
http://w1.weather.gov/xml/current_obs/seek.php?state=or&Find=Find
e.g.,:
http://w1.weather.gov/xml/current_obs/KAST.xml
If you click on the link you'll get a rendered page. However, if you pull from it using normal rest methods or just wget, it delivers an xml file.
