kandi X-RAY | farmhash Summary
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.

QUESTION
I have a problem with my pods:
...ANSWER
Answered 2017-May-29 at 17:05There 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
andar
tools to remove farmhash.o from Pods/Google/Libraries/libGGLCore.a and reconstruct it.
QUESTION
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.
...ANSWER
Answered 2017-Mar-16 at 07:42From 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:
