A page site for a stock trading platform makes real-time market data available: http://iextrading.com/tops/ This web page appears to use javascript and socket.io to stream market data to the browser. I would like a developer to create a simple java application (note: not javascript) to collect and process the data (e.g. print it out). The java application should use as few additional libraries, as possible (e.g. core java, plus maybe one or two others) and those libraries should be mainstream ones. Skills: Java (development) JavaScript (understanding)

Write some code which can generate SLR table and parsing tree for given grammar. First of all, assume we have a text file contain grammar. Program should at first identify TERMINALS and NON-TERMINALS from grammar and should generate two new text files named "TerminalList.txt" and "NonTerminalList.txt" which stores terminals and non-terminals respectively. After that, by using grammar and terminals and non-terminals, program should generate FIRST and FOLLOW of the given grammar and save them into two text files First.txt and Follow.txt. In a next step, after getting FIRST and FOLLOW, program should generate ITEM LISTS of the grammar and generate ItemList.txt file which have all ItemList of the grammar. Then, main thing SLR Table should be generated by program using ItemList. After getting SLR Table, program should generate Parsing Tree. Here I have attached demo files. Here GrammarList.txt is a input file and we will use this file to proceed further. All other files attached are output...

We want someone to create a call script so we can move email data from a excel file placed on a server. To be sent into the email service called "get response". We want it to send x amount of emails sent through API every hour or so. Since we have x amount of get responses accounts we have many different API's, so we want to be able to plug a different api on the fly if needed so the email data can feed into a different get response account.
