At times there is a need to control order of execution of triggers. This could be due to business requirement but also as a way to control history of a record I usually don’ t see people put any way to prevent trigger nesting, example update trigger updating same records would fire the trigger again.
RabittMQ RPC Request/Response example using hoplin.io library Following example creates RPC client and then setups Async response handler, which follows by the request to get processed. Hoplin client supports both Direct-Reply and Queue per Request/Response patterns. This is the binding that is used to create our client.

We need to count a number of transitions in a bit string from 0->1 and 1->0. I needed this in order to determine Uniform Descriptor in Local Binary Patterns(LBP) Samples 0000 0000 (0 Transitions : Uniform) 0x0 1110 0011 (2 Transitions : Uniform) 0xE3 0101 0000 (4 Transitions : NonUniform) 0x50 0000 1010 (4 Transitions …
This is a small snippet of how to calculate hamming distance in cpp with small bit of assembly for doing a population count. Code typedef unsigned long long hash_t; #include #include int popcount64(const hash_t& val) noexcept { int ret; __asm__ (“popcnt %1, %1” : “=r” (ret) : “0” (val)); return ret; } int hamming_distance(const hash_t& …
DRAFT This is the first article in the series on Image Comparison using Local Binary Patterns.Complete code is on github lbp-matcher We will start off by looking at different methods of comparing histograms. Histogram Intersection Log Likehood Chi Squared Kullback Leibler Divergence All our operations will be performed on 8bpp(bits per pixel) images anything that …
This is a series of small articles on Image Comparison using Local Binary Patterns. Topics I like to cover will include Histogram Comparsion Local Binary Patterns Perceptual Hashing From there we will go into building a system that can recognize same words/images in a document.
Small utility for dumping Leptonica Pix data to the screen. void dump(PIX* pix) { int_t w = pix->w; int_t h = pix->h; int_t wpl = pixGetWpl(pix); l_uint32* data = pixGetData(pix); l_uint32* line; printf("\n"); printf("Depth : %d \n", pix->d); for (int_t y = 0; y < h; ++y) { printf("%04d : ", y); …
This applies to Windows only machines. I have GitLab running and was adding a new ‘ssh key’ from windows that was generated using a standard ssk-keygen command but was reciving following error: “Fingerprint cannot be generated” Command used to generate key: ssh-keygen -t rsa -C “gbugaj@localhost” -b 4096 This produces a key in ‘id_rsa.pub’ file, …
