Count After Skip MongoDb -

-

I have such a collection 

  {"_id": ObjectId ("54368d9125c3dc7c1f43295f") "Nome": "John", "Eta": 30, "Data": ISOAD ("2014-10-09T10: 30: 00.000Z"}} {"_id": ObjectID ("54368d9c25c3dc7c1f432960"), "Nom" "Paul", "Eta": 31}   
 and I do this query  
  db.coll.find ({eta: {$ gt: 30}})   
 My result is a document (Paul)  
  db.coll.find ({eta: {$ gt: 30}}) .count () // 1   
 If I do  
  db.coll.find ({eta: {$ gt: 30}}). Skip (1)   
 I do not have the results, and it's okay. But if I do this  
  db.coll.find ({eta: {$ gt: 30}}. Skip (1) .count ()   < P> My result is 1   
 
 
 From the document for:  
 
 By default, the Count () method ignores the effects of the cursor. Skip () and cursor.Limit (). Set the SQL Limit to consider the effect of these methods.   < P> then you can supply an alternative parameter called  applySkipLimit  to apply (code). They are, if you want to effect it (): ( < / P>  .count (true);

python - Receiving "KeyError" after decoding json result from url -

-
I am new to Python I am trying to parse JSON result from a URL. Basically, I was using the following: response = urllib.request.urlopen (url) json_obj = json.load (response) It should be a stroke "str 'not' bytes' in the lines of a given" JSON object, so after searching on the StackoverView Flo, I decode the response in this way: F = urllib.request.urlopen (Url) charset = f.info (). Get_param ('charset', 'utf8') data = f.read () decoded = json.loads (data.decode (charset)) If I print "decode" I is as follows: { 'link': { 'summary data': 'https: // localhost / piwebapi / streams / p0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / summary' 'value': 'https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTExNQU42NDIwXFNJTlVTT0lE / price ',' InterpolatedData ':' https: // localhost / Piwebapi / streams / P0_7qHaW4UHU-RlCaz8tpasAAQAAAAU0hJTE...

.net - Creating a new Queue Manager and Queue in Websphere MQ (using C#) -

-
"itemprop =" text "> I am writing applications that use WebSphere MQ to send messages. My unittests (for flow), I want to verify that I have put the correct message on the response queue. I am trying to figure out how to do this. My main obstacle is that I think it might be scary to clear the queue before running in my queue because the same queue can be used by other applications, I thought a decent solution would be a new line The manager will remove the queue for my solidarity and after using it. So my question is: Is it possible to use C # by using queue manager and queue? After the For future reference and future people, who want to make queues. I thought how to make and remove IBM MQ QE (not quenhers) with PCM messaging. It is not very simple, but it can be done. We have implemented it in a library and it is being used to create and delete commands before and after integration tests. The most important part of the code in this library is shown in the...
