You must know: contenteditable, in particular the little range/caret navigation differences between the different browsers. Polymer knowledge is an advantage but not a must. The idea behind the app/component is to develop a text editor based on and extendable via custom elements. Your job will be to polish caret navigation issues. This is about an open source project, so you might be interested to join as a collaborator/maintainer. The offer is intended for single developers unless you are a company willing to collaborate on and benefit from the project via contribution of finances and/or development time.

We are a blog and forum that currently receives about 300k organic pageviews a month.We will use these to advertise this project. In addition we have an organically grown 10k person Facebook group and 100k person mailing list that goes to inbox (not spam). We are looking for someone to help us program a custom (***not wordpress***) website that will allow us to easily enter electronic products with various specs. These products should be able to easily be compared on the frontend by users visiting the site. They need to be linked to shareasale api that will allow for realtime price updating of lists of various shops that are offering that product for sale. We have several sites to model after to give an idea of what we're looking for, but we don't want to replicate exactly their site, just use as a base model to show what we're aiming for in terms of showing product specs clearly. And be able to show for example, this model is 22% more powerful than this one. This product is 15% wider...Etc.... Ideally we'd also like to eventually get this website functionality into an Android app. The catch is that we are looking for a partner to share profits with. We will enter the products into the database and provide all advertising for the site, but the programming of the custom site is slightly beyond us. This may be a bizarre proposition, but know that we aren't starting from ground zero. We are a well respected website in this niche and come with real assets to get the site of the ground and running.

Hash Tables Jordon Mecier In order to store positional information, we will need to construct a data structure. We will implement a hash table. The Hash table will point to smaller data structures. Hash tables store the data efficiently and will consume less memory if given a close approximation of expected keys. The benefits of using a hash as compared to an array is that we will not have to waste time shifting element, therefore there is no extra use of memory. The insertion time of a hash table list is O (1) time, the deletion time of a hash is also O (1) time. This way we can use the use the hash function to store the given key. In addition, we can locate the value based on the same hash function to search for the keys. For the purpose if efficiency well will use a pre-determined postal codes and coordinates from the US Postal Service. The coordinates will point to the CITY, which will be the indexed to the postal codes for the hash table. Currently there are 43,583-recorded postal codes In order to do this we the hash table will need a capacity of large enough to accommodate the postal codes. By default hash table capacity is set to 16, in our case we will need specify a higher value let us say 2^13. This will give enough space to reduce the first round of expected collisions. Using this many keys will not affect speed of the program it will remain in O (1) time. In order to do this I will implement a separate chaining to the hash table that will as a linked list. As the data comes into the system the key, the city string hashed in to an integer producing the hash value. The value mapped to a particular index in the hash tables. The more entries the more collisions there will be. Collisions are inevitable so we will use the linked list of colliding elements just like an offset table. The hash table with the linked list, depending on the hash function the worst case would be big O (n). Which would place all key into one index and you would just have long list. A “good” hash function distributes all keys will equally among the lists. The offset table will enable collisions to occur with minimal impact on CPU speed, by expanding the list to accommodate the data. To avoid collision, which are inevitable in hash table unless its “Perfect” there will need to be a collision avoidance in place such there will need to be hashing functions in place as entries allocated. In this case, we will need to apply an algorithm to diffuse the situation that two clashing keys fighting for the same index. In these cases, we may need to have use one of the following: Three hash functions 1. Division method a. H(k) = k mod m i. This situation is bad if m has common factor with k 1. If m is always even and k is always even 2. Multiplication method a. H(k) = [ ( a * k) mod 2w]  shift right w-r i. This is w bit machine 3. Universal hashing: h (k) = [(ak+b) mod p] mod m a. A and B are random {​0,1,2,3, p-1}​ p b. P is prime c. Worst case keys k1 !=k2; d. 1/m probability if it happening e. Linearity of expectation. f. Expected length of a chain g. Very few conflicts in expectation h. Dynamic and works for searching inserting and deleting it runs in O(constant time) and randomized i. Choose hash function randomly from set of Hash function Universal hash family. This way will not need to assume anything about the keys. j. H will have a universal hash family ( a set of hash function) we ned the probability that 2 key map to the same value is very small The use of a hash will be suitable for inserting, searching, and storing. This is dynamic data structure that can expand, and contract during runtime, to accommodate for the high demand of the Application data needed to be stored. Retrieving information will be slightly slower due to the unsorted nature of the hash. There are many different implementations of hash tables; it is a highly modifiable data structure capable of handling and immense amount of data. http://www.cs.princeton.edu/courses/archive/spr03/cs226/lectures/hashing.4up.pdf http://geotag.sourceforge.net/ https://www.youtube.com/watch?v=0M_kIqhwbFo https://en.wikipedia.org/wiki/Hash_table#Separate_chaining http://pzemtsov.github.io/2015/12/14/choosing-the-hash-maps-capacity.html https://en.wikibooks.org/wiki/Data_Structures/Hash_Tables http://www.cs.uregina.ca/Links/class-info/210/Hash/index.html
