Vote count: 0 I have data that requires two types of access: a unique identifier to retrieve a single row the retrieval of a batch of rows by a field equalling False The main table can contain many fields (e.g., 100). In DynamoDB I have a schema defining a primary key and a Global Secondary Index defining a field of KeyType Number which I set to 0 or 1. The table itself contains many fields so this set-up is expensive. i.e. many fields are copied to the Global Secondary Index when the main table changes. Can it be better to store the primary key of the main table in the Global Secondary Index and then perform individual looks-up from the rows retued by a Global Secondary Index Query? asked 2...

Vote count: -1 Given an image, say a colored 500x500 px 72dpi, with visible watermarks in it. I want to detect if the image contains some watermark or not. As a follow up I would like to remove that too. I am quite new to Image Processing and would like to know what all methods/techniques exists in recognizing watermarks in an image. There was not much that I could find related to this on Stack Overflow also. There was just this link Removing watermark out of an image in opencv, but it is not a generic approach. Any guidance is much appreciated. I have attached a sample pic, from google search. We could see the watermark "Preview" in the image. Any possible approaches to detect it? asked 1 m...

Vote count: 0 I've got Regex targeting alpha-numeric strings that are product numbers (all will be CAP/number combinations of various lengths) wrapping these product numbers in bold tags for hundreds of generated HTML emails. This worked great to bold product numbers, but also captures random parts of URLs and hex colors in my HTML email's tags attributes.

Vote count: 0 I'm unable to find an answer to this, or I'm not looking in the right place, but I'm trying to find a way where I can group a number of elements (panels) inside one large panel using both AngularJS and Bootstrap. So for example, I have around 60 or so mini panels that represent customer contact forms. All of these forms sit inside one large panel with an ng-repeat. I am wanting to somehow group my contacts by different criteria (e.g By State code or by Company Type, etc.) from a dropdown control. I would like all contacts to be shown in the one panel but segregated by a .page-header (a similar setup to the example below): Has anyone seen any examples of this anywhere, or have a...

Vote count: 0 Using rajawali library. I am using a sphere to show a 360 photo, with sphere's scaleX set to -1 and camera's position to Vector3.ZERO, I am able to see the 360 photo from the inside.

Vote count: 0 I am making a simple game that involves users pressing unbuttons. Each time the user presses a button I want a sound to play. The sound file that I want to play is 3 seconds long. However it is highly likely that the user will press 1 or more uibuttons onscreen within the 3 second window that the sound is playing. So at the moment if a second UIButton is press while the sound is playing than the sound will not play. How can I have it so that the buttons play the sound even if the the original sound is playing? import UIKit import AVFoundation class ViewController: UIViewController { var player:AVAudioPlayer = AVAudioPlayer() override func viewDidLoad() { super.viewDidLoad() let...

Vote count: 0 I have a page in which I am pushing some javascript using google tag manager. The javascript code has a function which executes on DOM ready and modifies certain elements on the page if it is being accessed from a mobile device. The code works fine when the page directly open in the browser but if we move out from the page by clicking a link and come back again by using the browser back button the page does not get modified that is either the code from the tag manager is not getting push into the page or somehow the code is not executed. asked 41 secs agodevkaustav Let's block ads! بخوانید...

Vote count: 0 Write a program that finds the number of vowels (‘a’, ‘e’, ‘o’, ‘i’, ‘u’) in a command line argument list. Use a separate thread to do the count for each command line argument. Thus if you have 5 command line arguments, you should spawn 5 threads. Once all threads have finished their work, you should print the total number of vowels found. Example program runs: java VowelCounter Hello Hello see you in Italy in Venice Number of vowels: 15 Once you have the above working, add an additional complication. Let’s imagine that we will be reading the words in from a file and there will be many words. Modify your program so that we will store the result for each word that is processed. ...
