Dimensional Data

You might have an application with a huge amount of user-generated content coming daily and need to moderate content automatically. It’s a pain to moderate content manually because it takes lots of man-hours. How about using artificial intelligence with IDE Software for that? It will instantly detect inappropriate content prevent form going public. What is the Content Moderation API by DeepAI? DeepAI is a very popular source among artificial intelligence content seekers. It provide researches, guides, news and APIs of artificial intelligence. You can easily grab an API key by creating an account and access all of their artificial intelligence APIs. Just visit this link, create an account and then go to the dashboard and you will have your API key. https://deepai.org/ Is it free to use Deep.ai automated content moderation? When you register, you will have $5 USD free credit which is equivalent to 10,000 requests. No credit card required for the registration. After the registration, you only need to pay $0.50 USD per 1000 requests or there are some enterprise packages you can discuss with them. What Deep.ai artificial intelligence APIs are available to use in my Delphi application? They provide numerous amount of APIs. You can check their APIs form this list. Most of them also have a live demo in their product page. https://deepai.org/apis One of their powerful API is the “Content Moderation API”. This API give you the all details to moderate the content. Once you supply and image to the API, it will provide you “Not safe for work” score, description about inappropriate content, the rectangle area of the inappropriate content, and the confidence score which is one if 100% confidence. This API can detect adult content, hate symbols, guns and offensive words. How do I use the Content Moderation API? We can access all of the DeepAI APIs using a REST client including this content moderation API. A simple curl request for this API is like this: curl –data ‘image=YOUR_IMAGE_URL’ -H ‘api-key:API_KEY’ https://api.deepai.org/api/content-moderation It’s self-explanatory and you have provide the image URL or local image file as “image” and the API key as a header value. Once you send the request, server will send a JSON response and you can parse it to have all moderation information about the image. Sample moderation would be like this: { “id”: “UNIQUE_ID”, “output”: { “detections”: [{ “confidence”: “0.83”, “bounding_box”: [ 118, 89, 21, 29 ], “name”: “Female Breast – Exposed” }, { “confidence”: “0.92”, “bounding_box”: [ 142, 92, 27, 27 ], “name”: “Female Breast – Exposed” }, { “confidence”: “0.54”, “bounding_box”: [ 168, 153, 19, 30 ], “name”: “Male Genitalia – Exposed” } ], “nsfw_score”: 0.9997197985649109 } } You have to parse the JSON array inside the JSON to get the results. How do I access the Deep.ai Content Moderation API from Delphi? We can use REST client component to access the this API and easily build a demo application. Let’s make a demo application which will draw a rectangle if one of the restricted content found. First add a TRESTClient, TRESTRequest and TRESTResponse components in to a form. Set the base URL of the client to the following: https://api.deepai.org/api/content-moderation Set the method of RESTRequest to rmPOST because we going to securely post the data. Then it’s the coding time. We need to set the image, […]

Join Delphi MVP Ian Barker as he shows how to get the modern Windows 10 look and feel using RAD Studio’s themes and some *very* cost-effective third-party controls. Get that truly modern WOW factor kickstarted with minimal effort – Ian will show you how. What is The Fluent UI? The Fluent UI Microsoft’s ‘design language’ for the Windows 10 operating system. It dictates how to modernize certain user interface elements to add depth, movement and affordance (whether or not a screen element looks like it can be clicked, slid or otherwise used by user interaction). This video takes us on a tour of what Fluent UI is along with some resources to look at and examples. At the bottom of this post you should see other suggested videos and resources about Fluent UI and user interface design in general.

Sooner or later software developers need to undertake the task of extracting data, transforming it into something useful and loading it into other forms of representation and storage (ETL). During that process we’ll often also need to then present that aggregated or extracted data as a visual representation. What is data visualization? Data visualization is the art of making the useful, usable. If we display a torrent of facts and figures such as city populations in the form of a table it is useful – but it’s not very usable or even readily understandable. It’s far easier for us to represent that collection of numbers as a graph; specifically a chart. We humans are very visual and we can absorb and comprehend quite substantial and even complex hordes of figures much more effectively when they are presented visually. How does TeeChart help with data visualization? Since the very early versions of the Delphi IDE a version of TeeChart from Steema has shipped as a free add-on. Even today with the far more comprehensive, evolved and advanced RAD Studio Delphi there is a free copy of TeeChart waiting for you to use if you tick the little checkbox during the installation process. This free copy of TeeChart has meant that many Delphi programmers have learned to use TeeChart to provide things like pie charts, line graphs and scatter plots in their programs to represent all sorts of data when the need arose. There is a paid version of TeeChart too which offers more advanced functionality but don’t be fooled by the “free” in the free version; it’s got plenty of power too and more than enough of it for many things you could find a use for. Here’s the video..

HTTP is one of, if not the most, widely used client-server protocols. It has been serving up our favorite web pages, blogs, and even this site for many years through its lifetime carried on the shoulders of the reliable TCP. But technology is evolving, and over time it has become clear there are some limitations with HTTP. The first thing is that HTTP is unidirectional. With HTTP, the client starts the request first and the server responds. So for every resource, the client is the one who polling for the resource. Added to that, HTTP expects that each interaction has a timeout before it’s assumed that the server is not responding. How can an IDE Software create a robust and scalable real-time Web Socket and Server? Let’s find out all the answers in this post. What are the solutions for the HTTP limitations? Long-polling serves as a solution to the limitations of HTTP based technology. In this case, the client sends request with a long timeout. This allows the server lots of time to reply without the connection expiring due to inactivity or an inability to respond. This was a solution for up to a certain level, but this is very resource hogging. It’s because the server resources are reserved and dedicated to the client during the long polling. Are Websockets a better solution for HTTP limitations? Yes, Websockets are a better solution to help mitigate some of the HTTP timeout limitation. Websockets can use HTTP to initialize the connection and, using the same TCP connection, upgrade to a websocket. With Websockets, we have a persistent bi-directional connection which is less resource intensive than long polling. Both the server and client can push messages any time. Today most of the web browsers support the Websocket protocol. Also the fifth version of HTML (HTML5) includes support for websockets. So in general, Websockets allow you to build real time client server applications. How do I implement websocket applications with Delphi or C++ builder? IPWorks has a complete solution to implement both Websocket server and client. It has following components: TipeCertMgr: This component used to store certificates. TipeWebSocketServer: This is the server component which accepts websocket client requests. TipeWebSocketClient: This is the client component which can connect to a websocket server and send or receive data. TipeWebSocketProxy: This component will accept Websocket connections for a websocket server and instead redirect to another server. By using these components you can develop a complete Websocket client and server application. These components are native and doesn’t need any external libraries. Also the components are optimized and work efficiently. It’s very secure with the WebSocket Secure 256-bit encryption. These components are thread safe. As an added bonus they also have a good documentation to get started: https://cdn.nsoftware.com/help/IWF/dlp/ How do I use IPWorks WebSockets? IPWorks provide a free trial version of their WebSocket component pack for both Delphi and C++ builder. You can evaluate those components in your application.
