Elasticsearch IntroductionElasticsearch (ES), an open source search engine based on Apache Lucene (TM), can be considered as the most advanced, best-performing and most functional search engine library in the world, whether in open source or proprietary domain.However, Lucene is just a library. To play a powerful role, you need to integrate it into your app using C #. Lucene is very complex, and you need to understand the search knowledge to understan

TS multiplexing gets the PES bare stream of audio and video. In general, the length of each TS packet is 188 bytes, and there is also a 204-byte, which is to add 16 bytes of Rs redundancy check information after each packet. In this case, the 188 bytes are analyzed, and the rest are similar.To i

Recently, I came up with an idea on Android: how to use OpenGL ES to draw a 3D image in the background, and then save the drawn image as a bitmap format... After several days of thinking, I tried a variety of methods, but none of them worked. At first I tried the glsurfaceview method, but this would lead to a connection between my activity and the rendered stuff, the result I want is that in any case, my master acivity cannot have any relationship wit

I am so ashamed to myself. I have been looking for a long time to use ndk to develop openggl es learning materials and I have not found any suitable materials (if I find that I cannot understand the English language, the program is too complicated and I cannot start with it), so I should first write it in Java, then I published an article about using ndk to accomplish the same function! The methods in the program are translated and understood on the O

. After the initial version of ECMAScript, work on the language continued and two more versions were quickly. But after ECMASCript 3 came out of 1999, there were no changes made to the official for a standard. Instead various browser vendors made their own custom extensions to the language, and Web developers were left to try and Support multiple APIs. Even after ECMAScript 5 is published in 2009, it took several years for wide browser support of the new spec, and most de Velopers continued to w

I 've been beating my head against the wall on this, so it's time to ask for help. I 've ported my game engine from iPhone to Windows CE (it actually started out policyears ago as a wince engine, so I 've developed it with portability in mind ). I 've also maintained a Windows build (full windows) all along for development. I'm having problems initializing OpenGL ES on the HTC Touch Pro 2. Now what is maddening is that one of the builds worked fine, b

I. Summary By accident, I saw this tutorial on Android Developers and made it step by step. Below is a record. Ii. How to draw OpenGL ES in Android To use OpenGL to draw images in Android applications, we must create a view container. The most direct method is implement.GLSurfaceViewAndGlsurfaceview. Renderer.The former is the container, and the latter controls the rendered content in the view. There are two other methods: surfaceview and textureview

In ES you need to aggregate according to App_categor, and the JSON query statements are as follows:{" query": {"bool": {" must": [{"Term ": { "Flag_color": "3" } }, { " term ": { " atype ":" 0 " } }, { " term ": { " Flag_off ":" 0 " } } ] } }, "Explain": true, "Aggs": {" appcategory": { "terms": {//The aggr

Start with an HTC Touch HD. Otherwise, it would be a pity that the big screen. The query shows that although the HD configuration is still acceptable, it is a pity that the CPU of Qualcomm's msm7201a is too shabby to support OpenGL ES. On glbenchmark, we can see that it only supports es1.0, and elasticsearch benchmark is normal. However, even so, there is always better than none. Start writing esProgramTwo problems are found: 1.
