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.

HTML/CSS - Automatically set height width from background image? -

-
Long time ... I do not think it's possible, but I'm shocked before! I tag anchor tags, all of which are background images, all 300px wide but their height is all the difference, is it really set to do without typing altitude? Is it to set the dimensions of BG URL? Thank you! I do not think people understand - my mistake is to hurry the question. Here is the code as an example: # ago -1 {width: 300px; Height: 410px; Background: url ('/ image-1.jpg');} # East -2 {width: 300px; Height: 420px; Background: url ('/ image-2.jpg');} # Pre-3 {width: 300px; Height: 430px; Background: url ('/ image-3.jpg');} # Pre-4 {width: 300px; Height: 440px; Background: url ('/ image-3.jpg');} & lt; A href = "#" id = "ex-1" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "ex-2" & gt; & Lt; / A & gt; & Lt; A href = "#" id = "pre-3" & gt; & Lt; / A & gt...

c - What is the address of buf (the local variable in the main function)? -

-
I had exercise with programming in c or classes and I followed the question: Is Buf (local variable in main function)? Either enter the answer in hexadecimal format (like 0x 8 "digits" 0-9 or A-F, 0xbfff0014) or in decimal format. Note here that we want the address of the buff, not its content. The code looks like this: int main (int argc, char * argv []) {while (1) {four buff [1024] = {0}; Int r; .... I then started the code and put the built code in the buff [1024] line and in Typed Gdb p & amp; Buf and it gives me results: 0xbffff0f0 But when I use it in this quiz it gives me the result that this value is wrong. My question is this: Is this the name of the Buff variable (P & E)? Or if not, why not? Exercise is done on the virtualbox machine, so I think everyone should be the same address There is no correct numerical answer, the address may vary from one time to another, it is a programming drill that you say the following three...
