Serverless Offline
Emulate AWS λ and API Gateway locally
...Once you run a function that boots up the Docker container, it'll look through the layers for that function, download them in order to your layers folder, and save a hash of your layers so it can be re-used in future. -

DeepCopy
Create deep copies (clones) of your objects
...You use __clone() and implement the behavior yourself. DeepCopy recursively traverses all the object's properties and clones them. To avoid cloning the same object twice it keeps a hash map of all instances and thus preserves the object graph. Alternatively, you can create your own DeepCopy instance to configure it differently. You may want to roll your own deep copy function. You can add filters to customize the copy process. DeepCopy\Matcher applies on a object attribute. DeepCopy\TypeMatcher applies on any element found in graph, including array elements. ... -

Tiny CUDA Neural Networks
Lightning fast C++/CUDA neural network framework
This is a small, self-contained framework for training and querying neural networks. Most notably, it contains a lightning-fast "fully fused" multi-layer perceptron (technical paper), a versatile multiresolution hash encoding (technical paper), as well as support for various other input encodings, losses, and optimizers. We provide a sample application where an image function (x,y) -> (R,G,B) is learned. The fully fused MLP component of this framework requires a very large amount of shared memory in its default configuration. It will likely only work on an RTX 3090, an RTX 2080 Ti, or high-end enterprise GPUs. ... -

Go Recipes
Collection of handy tools for Go projects
Visualize the distribution of code coverage in your project. This helps to identify code areas with high and low coverage. Useful when you have a large project with lots of files and packages. This 2D image-hash of your project should be more representative than a single number. For each module, the node representing the greatest version (i.e., the version chosen by Go's minimal version selection algorithm) is colored green. Other nodes, which aren't in the final build list, are colored grey... -

DwarFS
A fast high compression read-only file system for Linux, Windows
The Deduplicating Warp-speed Advanced Read-only File System. A fast high compression read-only file system for Linux and Windows. DwarFS is a read-only file system with a focus on achieving very high compression ratios in particular for very redundant data. This probably doesn't sound very exciting, because if it's redundant, it should compress well. However, I found that other read-only, compressed file systems don't do a very good job at making use of this redundancy. See here for a... -

Node Redis
A high performance Node.js Redis client
This library is a 1 to 1 mapping of the Redis commands. Each Redis command is exposed as a function on the client object. All functions take either an args Array plus optional callback Function or a variable number of individual arguments followed by an optional callback. Node Redis currently doesn't natively support promises (this is coming in v4), however you can wrap the methods you want to use with promises using the built-in Node.js util.promisify method on Node.js >= v8. ... -

HighwayHash
Fast strong hash functions: SipHash/HighwayHash
HighwayHash is a fast, keyed hash function intended for scenarios where you need strong, DoS-resistant hashing without the full overhead of a general-purpose cryptographic hash. It’s designed to defeat hash-flooding attacks by mixing input with wide SIMD operations and a branch-free inner loop, so adversaries can’t cheaply craft many colliding keys. The implementation targets multiple CPU families with vectorized code paths while keeping a portable fallback, yielding high throughput across platforms. ... -

Data structures and Algorithms library
...It contains the main data structures: single and double lists, special arrays (dynamic and of bits), many types of trees: multitrees, binary search trees, avl, red-black, randomized, treaps, splay and other interesting types. Several types of hash tables are implemented: separated chaining, open adressing with linear probing and double function hash; this last one has a garbage colector mechanism that allows to free deleted entries. Dynamic linear hash tables are implemented too. The main algorithms on graphs are implemented in an easy way and with good performance features. ... -

Class-Hashmap
Class Hashmap Code
This implementation uses a simple hash function that takes the modulus of the hash value with the size of the hashmap to get the index of the bucket where the key-value pair should be stored. It handles collisions by using a linked list to store multiple key-value pairs in the same bucket. The add method takes a key-value pair and adds it to the hashmap. If the bucket at the index returned by the hash function is empty, it creates a new linked list with the key-value pair. ... -

dirsynch
Directory synchronization tool
...It helps you to discover the status of each file in both directories: if it's only in one of them, if it's newer in one than in the other, or if they are simply equal. It also support file content comparison using a hash function, although it's very time consuming. After letting you to choose which files do you want to synchronize, it performs the right operations to make both directories equal (or not, if you want it different). The program can create a backup of the files before overwriting them. -

Ants-Review
A Protocol for Open Anonymous Scientific Peer-Reviews on Ethereum
The Project implements a Bounty-like protocol called Ants-Review to allow issuers to issue an AntReview, a bounty for peer-review in scientific publication, linked to requirements stored on ipfs which peer-reviewers can fill by submitting the ipfs hash which contains evidence of their fulfillment. After the submission of successful peer-reviews, they will be approved by an approver and payed in ANTS. AntReview Issuers are addresses, added by the owner of the contract, that can issue an AntReview via the function issueAntReview(). AntReview Approvers are addresses added by Issuers when they issue an AntReview or with the function addApprover(). -
