How do I move a spreadsheet from the root to my active folder?
You can use DocsList service to move your file after its creation, try like this : ... var ssOut = SpreadsheetApp.create(output_name); // Create a new spreadsheet, output_name. var root = DocsList.getRootFolder(); var folder = DocsList.getFolderById('your folder Id');// or use getFolderByName if you want var ssOutId = ssOut.getId(); var newFile = DocsList.getFileById(ssOutId); // begin the 'move to folder process' newFile.addToFolder(folder); newFile.removeFromFolder(root);// had to do it in 2 separate steps }

After new partition gets created insert partition info in another table through trigger
You can do it with DDL Trigers. Check out this link One important note from the author you should consider adding a partition is not DDL if Oracle decides to do it internally, it’s only DDL if it’s an end-user statement Implicit partition creation is a new feature of 11g and it reffers to the interval partition option.

Hoare partition : is this implementation more/less efficient than the standard partition algorithm?
I always prefer the standard Hoare's implementation. If you look at it, it is not very intuitive, but it has a visible advantage: Less number of swaps. While your implementation effectively always does exactly N comparisons and N swaps, the Hoare's implementation does only N comparisons, but it does not swap anything if it is not needed. The difference is significant in some scenarios. At first in a case you use environment where swaps or assignment of variables/objects is a costy operation. For example if you use C/C++ with arrays of objects. Another typical examples where Hoare's partition implementation performs better if when many of the items in your array are of the same value or when the array is almost sorted and needs just to swap a few items. In that cases Hoare's version perfor

MySQL table Partition with FLOOR function (partition function not allowed)?
MySQL documents the partitioning functions here. The floor() function appears to have some special considerations. In this case, I think the issue might be that the division is returning a float/double result rather than a decimal result. This is easily fixed in your case because you do not need to do the division: CREATE TABLE `fact_events` ( `event_key` bigint(20) unsigned NOT NULL AUTO_INCREMENT, `event_type_key` tinyint(3) unsigned NOT NULL, `analytic_file_id` bigint(20) unsigned NOT NULL, `sdk_session_id` bigint(20) unsigned NOT NULL, `virtual_button_create_id` bigint(20) unsigned NOT NULL, PRIMARY KEY (`event_key`), KEY `idx_events_event_type` (`event_type_key`) ) PARTITION BY RANGE(event_key) ( PARTITION p0 VALUES LESS THAN (0), PARTITION

Can the PowerShell commandlet move-item move a currently open file?
This is the classic producer-consumer problem, which is a well researched topic. Some solutions you might try are checking the file's last write time. If it is well enough in the past, it can be moved without issues. Another one would be trying to open the file with exclusive access. If it fails, the file is still being used by the producer process. Othervise, close the file and move it. Some examples are like so, # List files that were modified at least five minutes ago gci | ? { $_.lastwritetime -le (get-date).addminutes(-5) } # Try to open a file with exclusive mode try { $f1 = [IO.File]::Open("c: empfoo.txt", [IO.Filemode]::Open, [IO.FileAccess]::Read, [IO.FileShare]::None) # If that didn't fail, close and move the file to new location $f1.Close() $f1.Dispose()

Mongodb balancer move failed: chunk too big to move. But it's not
Looks like as known old bug https://jira.mongodb.org/browse/SERVER-9365 I have 30MB chunks about 280K docs. And mongo can not move it becouse it contain more then 250001 docs and fill error "chunk too big to move". We have situation that chuk not to big to split, and "not to small" to move. I reproduced that localy. I created collection of 1 chunk with 36b docs (8.58MiB per chunk). If docs is 250001 or less chunk moved manualy as expected. If docs 250002 or more I got a error "chunk too big to move". Chunk size in settings 64MB. Work arround: If you planed use collection with small docs - pre-split collection so that the documents were less then 250K.

How to move a character over a display so that it appear to move with same velocity on all devices
You can get the width of the device and then just divide that by something (like divide by 10 for 10% or 100 for 100%) and then have movement happen in relation to size of the screen. The character will still move differently, but it won't be as different as a set amount. To get the width of the screen you can do this: Display display = getWindowManager().getDefaultDisplay(); Point size = new Point(); display.getSize(size); int width = size.x; int height = size.y; Then do something like: x=x+(width*.01); to add 1% of the screen

How do I move a shared_ptr object between containers with move semantics?
You're not invoking the move constructor. Nothing about the emplace_back call makes it clear v1 is no longer needed. You probably need a std::move in there. You probably want: v2.emplace_back(std::move(v1.back())); v1.pop_back();

How can I remove the root node and make the first child the new root node with XSLT?
Add a rule to the identity transform that adds nothing to the result tree for your document element other than the processing of its children: <?xml version="1.0" encoding="US-ASCII"?> <xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"> <xsl:template match="/*"> <xsl:apply-templates select="*[1]"/> </xsl:template> <xsl:template match="@*|node()"><!--identity for all other nodes--> <xsl:copy> <xsl:apply-templates select="@*|node()"/> </xsl:copy> </xsl:template> </xsl:stylesheet> (edited to be agnostic to the name of the document element) (edited again to only preserve the first child element of the document element)

Including from child theme root or else include from parent theme root
To answer your question directly based on your sample, i would not check to see if the file has been placed in the child theme. If a child-theme developer has customized the file, they can simply declare the function and include their own file (wherever they place it). There is no risk of code duplication because your sample function is simple enough. Even if you simplified your code for the purposes of placing it here....you can always keep includes wrapped in a very simple function that can be declared by a child theme. This will keep PHP running efficient and not having to check for files all the time.

Is a private move constructor to prevent move?
But will the following code then compile (in C++11/14): No, it will not. The presence of a user-declared copy constructor should inhibit the implicit generation of a move constructor. Per paragraph 12.8/9 of the C++11 Standard: If the definition of a class X does not explicitly declare a move constructor, one will be implicitly declared as defaulted if and only if — X does not have a user-declared copy constructor, — X does not have a user-declared copy assignment operator, — X does not have a user-declared move assignment operator, — X does not have a user-declared destructor, and — the move constructor would not be implicitly defined as deleted.

Why only one active partition in MBR
Wikipedia has a nice article on MBR with a lot of useful links. "Only one active partition" seems to be a design choice from the early IBM/DOS bootloader, and has remained that way since. Basically they defined multiple active partitions as an error, and checked for this error at boot. It kind of makes sense because you can only boot one operating system at a time anyway, and a forced single active partition will prevent ambiguity. If I recall correctly LILO and possibly GRUB (linux bootloaders) don't mind if there are multiple active partitions, so I think this is a DOS/Windows issue mostly. As for your questions. An "active" partition only means that the first byte is different from an "inactive" partition. There's no advantage or disadvantage, it's just a flag. Partition information

Option 1: In your dashboards controller, change to: @user = current_user @dashboard = current_user.dashboard This will also prevent users from seeing other user's dashboards. Option 2: Now, if users can see other user's dashboard fine, then change your route: root :to => "dashboards#find", as: :authenticated_root and in your dashboards controller: def find redirect_to user_dashboard_path(current_user, current_user.dashboard) end

Pig Latin Partition By clause
What is the use of "Partition By" clause in Pig Latin? This allows you to set the Partitioner of your choice. Pig uses the default one i'e HashPartitioner except for order and skew join. But sometimes you might wanna have your own implementation to enhance the performance. Partition By helps there. Also please provide an example usage. DATA = LOAD '/inputs/demo.txt' using PigStorage(' ') as (no:int, name:chararray); PARTITIONED = GROUP DATA by name PARTITION BY org.apache.pig.test.utils.SimpleCustomPartitioner parallel 2; Does it allow only custom partition or allows partition by column? It is just to specify custom partitioners and not to partition directly based on some field. See PIG-282 for more details.

Cassandra: choosing a Partition Key
Indexing in the documentation you wrote up refers to secondary indexes. In cassandra there is a difference between the primary and secondary indexes. For a secondary index it would indeed be bad to have very unique values, however for the components in a primary key this depends on what component we are focusing on. In the primary key we have these components: PRIMARY KEY(partitioning key, clustering key_1 ... clustering key_n) The partitioning key is used to distribute data across different nodes, and if you want your nodes to be balanced (i.e. well distributed data across each node) then you want your partitioning key to be as random as possible. That is why the example you have uses UUIDs. The clustering key is used for ordering so that querying columns with a particular clusteri
