With Parallel List Comprehensions language extension,
[(x,y) | x <- xs | y <- ys]
is equivalent to
zip xs ys
Example:
[(x,y) | x <- [1,2,3] | y <- [10,20]]
-- [(1,10),(2,20)]
A few pre-requisites in the build.gradle for vectors to work all the way down to API 7 for VectorDrawables and API 13 for AnimatedVectorDrawables (with some caveats currently):

Use tf.nn.sparse_softmax_cross_entropy_with_logits, but beware that it can't accept the output of tf.nn.softmax. Instead, calculate the unscaled activations, and then the cost:
logits = tf.matmul(state_below, U) + b
cost = tf.nn.sparse_softmax_cross_entropy_with_logits(logits, labels)

If we want to order the data differently for per group, we can add a CASE syntax to the ORDER BY.
In this example, we want to order employees from Department 1 by last name and employees from Department 2 by salary.

You can expose values from JSON column as computed columns:
CREATE TABLE ProductCollection (
Id int identity primary key,
Data nvarchar(max),
Price AS JSON_VALUE(Data, '$.Price'),
Color JSON_VALUE(Data, '$.Color') PERSISTED
)
If you add PERSISTED computed column, value from JSON tex...

NULL is a special case when it comes to comparisons.
Assume the following data.

2 2
With a query:

WHERE someVal = 1
would return id 1

The HTTP message body can be compressed (since HTTP/1.1). Either by the server compresses the request and adds a Content-Encoding header, or by a proxy does and adds a Transfer-Encoding header.
A client may send an Accept-Encoding request header to indicate which encodings it accepts.
The most com...
It is possible to compress an HTTP response message body more than once. The encoding names should then be separated by a comma in the order in which they were applied. For example, if a message has been compressed via deflate and then gzip, the header should look like:
Content-Encoding: deflate, g...
The client first sends a request with an Accept-Encoding header that indicates it supports gzip:
GET / HTTP/1.1\r\n
Host: www.google.com\r\n
Accept-Encoding: gzip, deflate\r\n
\r\n
The server may then send a response with a compressed response body and a Content-Encoding header that specifies...

Ruby moves up on ancestors chain of an object. This chain can contain both modules and classes. Same rules about moving up the chain apply to modules as well.

The @switch annotation tells the compiler that the match statement can be replaced with a single tableswitch instruction at the bytecode level. This is a minor optimization that can remove unnecessary comparisons and variable loads during runtime.
The @switch annotation works only for matches again...
This creates a simple archive of a folder :
tar -cf ./my-archive.tar ./my-folder/
Verbose output shows which files and directories are added to the archive, use the -v option:

For archiving a folder compressed 'gzip', you have to use the -z option :
