kandi X-RAY | farmhash Summary

farmhash is a JavaScript library typically used in Server, Runtime Evironment, Nodejs applications. farmhash has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can install using 'npm i farmhash' or download it from GitHub, npm.

Node.js implementation of Google's FarmHash family of very fast hash functions. FarmHash is the successor to CityHash. Functions in the FarmHash family are not suitable for cryptography. A fast, cryptographically-secure alternative is HighwayHash. As the V8 JavaScript engine only natively supports 32-bit unsigned integers, the 64-bit methods return strings instead of Numbers and the 128-bit methods are not implemented. This module uses FarmHash v1.1.0 (2015-03-01). It has been tested with Node.js 10, 12 and 14 on Linux, OS X and Windows. Pre-compiled binaries are provided for CPUs with SSE4.2 intrinsics. Use the npm install --build-from-source flag to gain performance benefits on more modern CPUs such as those with AVX intrinsics.

There is a symbol collision between the generated contents from the Firebase/Performance and Google/Core pod specifications.

I see three options:

Remove Google/Core from Podfile
If Google/Core functionality is needed, convert it to Firebase and remove Google/Core from Podfile
Use lipo and ar tools to remove farmhash.o from Pods/Google/Libraries/libGGLCore.a and reconstruct it.

QUESTION

Bloom Filter hash is returning far too many collisions

Asked 2017-Mar-16 at 07:42

I have been trying to implement my own (simple) Bloom Filter but am stuck on hashing, I understand the concept of hashing the item multiple times and populating the bit array with the indices.

However, I am seeing a ton of collisions in my hashing, I am using 1 hash algorithm (I have tried FNV, murmurhash and now farmhash) with various seeds (based on current nanoseconds).

I must be doing something wrong, I am calculating the k functions by following the information here and setting the same amount of seeds.

Any help would be great, thanks.

From what I remember from Bloom filters, a collision happens when all k indexes for a particular value match those of a different value.

It looks like you count a single bucket (this.m[index]) having been set previously as a collision.

The following (untested) code should count the actual collisions:
