A simple OGL 4.0 GLSL shader program that shows how to map a 2D texture on a mesh. The program is executed with a phyton script. To run the script, PyOpenGL and NumPy must be installed. The texture matrix defines how the texture is mapped on the mesh. By manipulating the texture matrix, the textu...

This is an Angular 2 wrapper library for Dropzone. npm install angular2-dropzone-wrapper --save-dev Load the module for your app import { DropzoneModule } from 'angular2-dropzone-wrapper'; import { DropzoneConfigInterface } from 'angular2-dropzone-wrapper'; const DROPZONE_CONFIG: Dropzon...

To ensure that a GPU version TensorFlow process only runs on CPU: import os os.environ["CUDA_VISIBLE_DEVICES"]="-1" import tensorflow as tf For more information on the CUDA_VISIBLE_DEVICES, have a look to this answer or to the CUDA documentation.

import tensorflow as tf sess = tf.Session(config=tf.ConfigProto(device_count={'GPU': 0})) Bear in mind that this method prevents the TensorFlow Graph from using the GPU but TensorFlow still lock the GPU device as described in this an issue opened on this method. Using the CUDA_VISIBLE_DEVICES se...

To use a particular set of GPU devices, the CUDA_VISIBLE_DEVICES environment variable can be used: import os os.environ["CUDA_DEVICE_ORDER"]="PCI_BUS_ID" # see issue #152 os.environ["CUDA_VISIBLE_DEVICES"]="0" # Will use only the first GPU device os.en...

By default, TensorFlow pre-allocate the whole memory of the GPU card (which can causes CUDA_OUT_OF_MEMORY warning). To change this, it is possible to change the percentage of memory pre-allocated, using per_process_gpu_memory_fraction config option, A value between 0 and 1 that indicates wh...

Each x sigil call respective sigil_x definition Defining Custom Sigils defmodule MySigils do #returns the downcasing string if option l is given then returns the list of downcase letters def sigil_l(string,[]), do: String.Casing.downcase(string) def sigil_l(string,[?l]), do: String.Casing...

This is just the other way of writing Multiple OR conditions. This is not the recommended approach because in regular approach when the condition evaluates to true, it stops executing the remaining conditions which save the time of evaluation, unlike this approach which evaluates all conditions firs...

Copy the content into a file and save the file as .iex.exs in your ~ home directory and see the magic. You can also download the file HERE # IEx.configure colors: [enabled: true] # IEx.configure colors: [ eval_result: [ :cyan, :bright ] ] IO.puts IO.ANSI.red_background() <> IO.ANSI.white() ...

By taking Treeview: Basic example, it can be shown how to customize a basic treeview. In this case, we create a style "mystyle.Treeview" with the following code (see the comments to understand what each line does): style = ttk.Style() style.configure("mystyle.Treeview", highli...

A simple OGL 4.0 GLSL shader program that shows the use of a interface block and a uniform block on a Cook-Torrance microfacet light model implementation. The program is executed with a phyton script. To run the script, PyOpenGL and NumPy must be installed. An Interface Block is a group of GLSL in...

This is how you install the gcloud command-line tool, which is a part of the Google Cloud SDK. $ curl https://sdk.cloud.google.com | bash

Create a Cloud SQL instance $dsn = "/cloudsql/PROJECT:REGION:INSTANCE;dbname=DATABASE"; $user = "USER"; $password = "PASSWORD"; $db = new PDO($dsn, $user, $password); //Whatever is your favorite MySQL connection method The important part here is /cloudsql/PRO...

App Engine does not allow writing to files, instead write to and read from Cloud Storage. Write to Cloud Storage $file = 'gs://<your-bucket>/hello.txt'; file_put_contents($file, 'hello world'); Read from Cloud Storage $contents = file_get_contents($file); var_dump($contents);
