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): //Build Tools has to be 24+ buildToolsVersion '24.0.0' defaultConfig { vectorDrawables.useSupportLibrary = true ...

Get the current date and time. public class Program { static void Main() { // create empty pipeline PowerShell ps = PowerShell.Create(); // add command ps.AddCommand("Get-Date"); // run command(s) Console.WriteLine(&quot...

(Caveat emptor: there are many, many programmers who go into absolute conniptions if they meet code that uses recordsets instead of commands and stored procedures.) <% dim rs, sql dim SelectedUser SelectedUser = request.form("user") if IsNumeric(SelectedUser) then SelectedUser...

The syntax for using the aws cli is as follows: aws [options] <command> <subcommand> [parameters] Some examples using the 'ec2' command and the 'describe-instances' subcommand: aws ec2 describe-instances aws ec2 describe-instances --instance-ids <your-id> Example with a ...

aws s3 ls Use a named profile aws --profile myprofile s3 ls List all objects in a bucket, including objects in folders, with size in human-readable format and a summary of the buckets properties in the end - aws s3 ls --recursive --summarize --human-readable s3://<bucket_name>/

A function declared inline may be defined in multiple translation units, provided that all definitions are identical. It also must be defined in every translation unit in which it is used. Therefore, inline functions should be defined in headers and there is no need to mention them in the implementa...

Once you understand how to create an HTTP Server with node, it's important to understand how to make it "do" things based on the path that a user has navigated to. This phenomenon is called, "routing". The most basic example of this would be to check if (request.url === 'some/pa...

$ mkdir backup_download_directory && cd !#:1 mkdir backup_download_directory && cd backup_download_directory This will substitute the Nth argument of the current command. In the example !#:1 is replaced with the first argument, i.e. backup_download_directory.

This is a TCP daytime client kept as simple as possible. #include <unistd.h> /* unix standard library */ #include <arpa/inet.h> /* IP addresses manipulation utilities */ #include <netinet/in.h> /* sockaddr_in structure definition */ #include <sys/socket.h> /* ber...

Phoenix framework is written in Elixir, and Elixir itself is based on Erlang language and leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems. Both languages are required for using phoenix framework. Following following step to install phoenix framework: 1...

First make sure you link against the logging library in your Android.mk file: LOCAL_LDLIBS := -llog Then use one of the following __android_log_print() calls: #include <android/log.h> #define TAG "MY LOG" __android_log_print(ANDROID_LOG_VERBOSE, TAG, "The valu...

ActionMailer supports three callbacks before_action after_action around_action Provide these in your Mailer class class UserMailer < ApplicationMailer after_action :set_delivery_options, :prevent_delivery_to_guests, :set_business_headers Then create these methods under the private ...

Using Ubuntu you have different ways to read a text file, all similar but useful in different context. cat This is the simplest way to read a text file; it simply output the file content inside the terminal. Be careful: if the file is huge, it could take some time to complete the printing process!...

With a clustered index the leaf pages contain the actual table rows. Therefore, there can be only one clustered index. CREATE TABLE Employees ( ID CHAR(900), FirstName NVARCHAR(3000), LastName NVARCHAR(3000), StartYear CHAR(900) ) GO CREATE CLUSTERED INDEX IX_Clustered O...

Non-clustered indexes have a structure separate from the data rows. A non-clustered index contains the non-clustered index key values and each key value entry has a pointer to the data row that contains the key value. There can be maximum 999 non-clustered index on SQL Server 2008/ 2012. Link for r...

When state_below is a 2D Tensor, U is a 2D weights matrix, b is a class_size-length vector: logits = tf.matmul(state_below, U) + b return tf.nn.softmax(logits) When state_below is a 3D tensor, U, b as before: def softmax_fn(current_input): logits = tf.matmul(current_input, U) + b ret...

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) In this c...

Saving a model in tensorflow is pretty easy. Let's say you have a linear model with input x and want to predict an output y. The loss here is the mean square error (MSE). The batch size is 16. # Define the model x = tf.placeholder(tf.float32, [16, 10]) # input y = tf.placeholder(tf.float32, [16...
