json - MongoDB - db does not show any collection after mongoimport -

-

I'm actually searching for MongoDB and Maps, promote inside, but I have a problem. The establishment of Mongodb was successful. After that, I tried to import json file to type these 2 commands before calling a Mongo in Terminal (I am working on Ubuntu 12.04 LTS):

< Pre> $ wget http: /media.mongodb.org/zips.json $ mongoimport - db mapreduce --collection zips --file zips.json

then I call I have received these alerts: 

  Mongodabi shell version: 2.6.5 connects to:   : The test server has startup warnings: 2014-11-04 04 20: 15: 12.280 + 0100 [initandlisten] 2014-11-04 T-20: 15: 12.280 + 0100 [initandlisten] ** Note: This is a 32-bit MongoDB binary 2014-11-04 T 20:15:15 12.280 + 0100 [Initandlisten] ** 32 bit builds are limited to 2 GB data (or at least -General). 2014-11-04 T20: 15: 12.280 + 0100 [initandlisten] ** Note that journaling is deferred for 32 bit and is currently closed 2014-11-04T20: 15: 12.280 + 0100 [initandlisten] ** See http://dochub.mongodb.org/core/32bit 2014-11-04T20: 15: 12.280 + 0100 [initandlisten]

And now when I want to show the archive, I Normally I type:

Show archive

but it does not show any archive << P>

and when I type

show dbs

< / Blockquote>

I got the terminal: < / P> 

  Administrator (empty) Local 0.078GB MapperData 0.078 GB Test (empty) ZIP (empty)

This means that the database ZIP is empty, but when I Open it, there are so many documents.

Can anyone help me? thank you in advanced. 

  Mongoimport - db mappedred - colonation zip - file zip json  < / Pre> 
 This command imports data in the  zips.json  file from the  zips  name store  mapread  database. 
 
 
  And now when I want to show the archive, I normally type: Show the collection but it does not show any collections. Like this:  
 
 
 By default, when you open a new  mango  client, then use this  test  database I.e. i.e.  without switched  all tasks will be done on the database  test  database. 
 
 Since the  mongoimport  command is executed on the  mapread  database, and the default  test  is not in the database, you will have  test  No collection is visible in the database 
 
 When you do  show DBS , it lists all the existing databases. You can see the new  Mapreads  database to be listed here.  zips  which you see here is a database that you accidentally created, and is not a collection in which you imported the data. 
 
 
  Which means the database zip is empty, but when I open it, there are so many documents.  
 
 
 Yes, the  database  named  zip  is empty; what you are looking for is  zip   Archive . Therefore, you need to issue commands:  use mapreads; , first to switch to the  MapRad  database, when you release the  show archive , you will see the  zips < / Code> archive.

c# - .net WebSocket: CloseOutputAsync vs CloseAsync -

We have a working ASP.NET Web API REST service, which is one of the methods of our controller, HTTPTTEX. .) Socket handler code looks something like this ... Public async task socket handler (AspNetWebSocketContext context) {_webSocket = context.WebSocket; ... while (! Cts.IsCancellationRequested) {WebSocketReceiveResult Results = _webSocket.ReceiveAsync (Input Segment, cts.Token) .Result; WebSocketsStateCollusocketState = _webSocket.State; If (result.MessageType == WebSocketMessageType.Close || currentSocketState == WebSocketState.CloseReceived) {// What should I use. CloseAysnc () or. CloseOutputAsync ()? _webSocket.CloseOutputAsync (WebSocketCloseStatus.NormalClosure, "Client Requested", cts.Token). Wait (); } If (currentSocketState == WebSocketState.Open) {...}}} .What is the difference between .CooseAsync () and CloseOutputAysnc ()? I tried both of them and they both seemed to work fine but some difference should be the same they both describe very similar to...

c++ - How to properly scale qgroupbox title with stylesheet for high resolution display? -

-
I am trying to apply a stylesheet for QGroupBox (QT4.8), which works on the normal screen ( 96 dpi) high resolution screen (Yoga 2 Pro, 3200x1800, 275 dpi, windows 8.1). The following style looks good on the 275 dpi screen, but the top margins on a regular 96 dpi screen are far too big. QGroupBox {border: 1px solid red; Range radius: 7px; Margin-top: 12x; } QGroupBox :: Title {subcontrol-origin: margin; Subcontrol-position: left above; Padding-left: 10px; Padding-right: 10px; } Changing the top-margin has an effect, but I did not get a proper setting which works on both screens. If I shorten the value, the content of the group box overlaps with the title on 275 dpi screen. I was also playing with units "East", "PX", "MX", "PT". Reading the document I would have guessed, "2 X" was the correct solution, which should be scaled with different screen resolutions. Without the stylesheet, the groupbox works well on both screens. ...
