Nine haskell problems. Requires the knowledge of DFA and Turing machines. I would like a price estimation. Cheers.
Haskell coder wanted for a simple project that's about half a day's work. You must have experience with Haskell!
Hi, We have a working multi threading socket server written in C which is basically working. To do production benchmark testing, we look to have this script ported to Erlang in order to compare resource usage and overall performance for both versions. Please bid only if you have experience writing socket servers in Erlang. Many thanks, Volker
Large-scale, multi-tenant webapp, which has already been written in Rails+AngularJS. We're evaluating Haskell for future development.
hi .. dear i have a small haskell task to be done.. can u handle this ? I can pay 15 $ for this small task
I need an Android app. I would like it designed and built. I need an app programmed using Erlang. The app should allow one to save on airtime by giving the option to extract a certain percentage of airtime from the owners phone. The app should also be able to show how much one has saved and should not allow one to withdraw the funds unless a certain amount of savings is reached.
I am a student, I need to finish this project asap In Haskell programming language. The Main objectives are: 1) create a similar test to an existing one, using my own data type by fitting my type on an existing library and test. 2) writing my own function test. More In: I created A Point data type, and a list of Points named PointList. In the optimization libarary there is a file which uses V2 data type, i want to replace the V2 with my data type . The next stage will be implementing: Input: 2 Sets of points - (called A and B) and a function for B (which can "move" all the points in the set) output: a set of points B' , which is created from applying the input function (many times) on B. after applying the given function on B our goal is to ...
Some beginner hands on haskell programming work need to be done asap. - Task is to Implement a simple library. Please contact me to get started right away.
Our project is a disappearing chat application. Users have a finite amount of time to text one other - individual or group - before the chat is deleted forever, permanently. Cross between WhatsApp and SnapChat. Need front and backend developed in Erlang language.
Need a highly optimized implementation of a purely functional data structure written in either Elixir or Erlang. No ETS tables or similar. The data structure is a multiset of integers, optimized for integers occurring in runs of consecutive numbers. Apart from the usual union, set difference, subset checks, max, min etc., it needs to efficiently be able to return a new multiset of all integers x: a < x < b, and also return a new multiset with only integers that are part of a consecutive run longer than n. The ranges are bounded inside a small integer, with some margin, i.e. around (-2^59, 2^59). The current implementation uses a linked-list to store the runs of integers as pairs (from,to). It will be provided as a reference implementation. There are unit tests, but they ar...

Hi, I need a simple program coded in Haskell. I also need an explanation (full explanation) on how I can run it using GHCi, from the command line. What the program needs to calculate is the maximum sub subsequence from an array of integers (both positive and negative). To do this, you need to create a random array of integers, with values between -30 and 30. I also need time and space complexity (done by :set +s in Haskell) for running in 4 different cases: 10 items, 100 items, 1000 items and finally 10000 items. That's it, very simple, code is mostly available online (for ex: Rosetta code, Haskell implementation fully done there). Actually, please use the code from the Rosetta site and expand it to meet these requirements. I have a low budget, as thi...

The concurrency problem must be illustrated using Finite State Machines(FSM) or Finite State Processes (FSP), and Erlang. The solution (Mutex) must also be illustrated in FSM/FSP and implemented in Erlang. • The background: Banking and Erlang • The concurrency problems using some high level description like FSM or FSP. How does this manifest itself in your Erlang implementation? • What is your solution idea/algorithm? (Mutex!probably) • Solution in Erlang including some analysis(tests, problems encountered).

...write the same plugin for another broker named emqtt that is written in erlang. When the client connects to the mqtt broker it uses an username, password and client id. The password is a token provided by another service that contains a base64 encoded identity and the signature for that identity. The plugin needs to validate that the identity is valid using the signature, decode the identity and extract some information to match with username and client id, let the client log in and generate a rule for which mqtt topics the client is able to publish and subscribe. The mosquitto plugin was written in C based on the mosquitto plugin architecture and do everything we need, your job is to implement the same plugin in erlang for the Emqtt broker that has its own different...

... Voice Over: Tired of having no visibility in your Erlang and Elixir clusters? Do you find out about your system crashing only when your customers start complaining? Figuring out what caused a crash feels like looking for the needle in a haystack? Look no further, there is a solution for your troubles! WombatOAM is the only operations and maintenance system purpose-built to understand the behaviour of Erlang and Elixir clusters. Regardless of you running a proprietary application or an open source one such as Phoenix, Riak, RabbitMQ or MongooseIM, WombatOAM works out of the box and gives you full visibility and control. Once you've installed WombatOAM, connect your Erlang and Elixir nodes using distributed Erlang and a secret cookie. W...

Hi. The job is about VKHS [1] project written in Haskell - a library for accessing VKontakte (Russian social network) and a simple CLI application. One of its functions is music downloading. The generic algorithm is : User 1) Logs in to his/her Vkontakte account 2) Lists music records, obtains meta-information and URLs 3) Downloads selected URLs to the hard drive. Meta-information contains fields like artist name, album name, song title, lyrics (if available) and so on. Unfortunately, downloaded MP3 files have excessive ID3v2 tags or no tags at all. The task is to fill ID3v2 tags with information available from meta-information provided by VK. Formal requirements are: 1) Write ID3v2 tags of every downloaded MP3/OGG file: Fill 'Artist' and 'Title' fields....

The work is to build an simplified SIP stack in Erlang. We will re-use an existing SIP implementation like esip: Most of the SIP libraries are implementing a lot of functionality not needed like: STUN, TLS etc. So this is an very simple stack, only with the "must have functionality”. Together with the SIP stack, we need to make an simple SIP application to demo the SIP implementation. So basically the work could be: 1) reverse engineer and figure out how esip is working (it’s not that well documented) 2) strip away functionality not strictly needed in esip (like STUN, TLS, codec etc) 3) build an application server using esip (and change from rebar to ) The developer should know Erlang/OTP (gen_server and gen_fsm), have an interest in
We are looking for an expert to help us support our eJabberd server. We are using a modified version of eJabberd XMPP server to run our service and we want to add more new services to our server such as VoIP and Video chat and many more things.
We look to create a multi threading socket server to parse incoming data and obtain responses via web service. Then send received response back to socket. The programming language is secondary. It may be written in Erlang, Java or other language that can be processed on a linux server. Functionality details: Base TCP socket server
Configurables: 
IP address
Port to listen to 
Max sockets
 Socket timeout 
Hex/ Ascii to set if incoming data are in hex/binary or ascii
 Primary parsing URL 
Secondary parsing URL

 Function flow:
 1. (BASIC) Listen to incoming connections from field devices with sim cards
 On incoming connection create new thread to process data on this socket 
When data are received call web service via cURL or other suitable means and pass data strin...
