This is an exciting chance to help a product that has a real shot of improving a space that has become outdated over decades. We hope you can help make this product a reality for everyone who takes pride in their inner city commute, but want to do so in a more stylish and portable way. We need help finding out where traffic originated from some top Kickstarter campaigns. These campaigns are of products that indirectly and directly compete with our product. The purpose of this research is to understand where they get traffic and how they got traffic. The desired outcome will allow us to know which channels to approach, how to approach them, and gain access to more backers to fund our campaign who have an interest in what we offer. Those who we're looking for understand how to find how traffic arrived to a page, discover the source that it came from, the approximate amount of people that came from that source, and what convinced them to come from that source.

I need for a client a small console app, or at least the DLL, that can communicate with a led outdoor display screen that a client has. It comes with a software called PowerLed where projects can be created and eventually text can be sent. However, I need something that can be automated as I need to feed this led screen with information that comes from another system. The person who applies has to have experience developing things like this. I have sniffed communication between screen and software, it creates a UDP channel and do several calls to the screen, however could not figure out what information to send exactly for it to update text, and I have no time for this right now. The controller board of the screen is this: http://en.led595.com/English/GoodDetail/62.htm The led screen is this: http://panel-e.com/en/proItem.aspx?id=640 Software that comes with the screen is: https://www.dropbox.com/sh/uvoq8bmi23vh6j5/AAC6By7hqvnZ1L53Tojp8vBVa?dl=0 The application you develop has to run on Windows environments and must be written in .net. However, if any other technology suits you better, and the app can be run easily on the command line, that should be fine.

Reverse engineer Tumblr Android app and make two custom Java methods: login(username, email, password) - gets all the required data for future methods postBlogArticle(title, article) - posts an article to logged in blog These two methods will be used on a desktop app, so we can't really reuse decompiled jar code, because it will depend on Android libraries. HTTPS traffic can be debugged using Charles, but there is this one Oauth signing part, that I cannot get done myself. We must reverse engineer all the Tumblr's app Oauth keys, we cannot create new ones.

I am looking for someone with experience in cracking hash algorithms with the help of GPGPU OpenCL. CUDA is also an option, but I prefer OpenCL. I have an algorithm which is attached as a C++ function. The algorithm is very similar to MD5. This algo always receives as input 8 hex bytes and the output is also 8 hex bytes (these are the pointers *a1 and *a2, if you open the attached file). Here is an example: If you call the algo with these parameters: *a1 = 0x479A6488 *a2 = 0xEF762984 this means the input hash is: 479A6488EF762984 then you will get result: *a1 = 0xC85FA91D *a2 = 0x3EE07454 So the final hash is: C85FA91D3EE07454 The goal is to calculate the initial hash when we have the final hash. Currently if we pick several thousand random initial hashes and we try to bruteforce the algorithm it successfully finds Final Hash the after several days when we use the CPU for computing. We want to use the GPU instead of the CPU. Several things are important: 1. When searching for a initial hash the GPU must be loaded at 100%. 2. How to "split" our algorithm so the calculation will use the GPU effectively (100%) Here is a video in which they are doing a similar thing, but for a different algorithm: https://www.youtube.com/watch?v=a2pyRYLE2Iw The software should run in Windows (7 or 8). Preferably the solution should come as a Visual Studio project. The budget can be negotiated.

Task that need to be completed: 1. Bypass the anti-cheat. 2. Use / edit values using Cheat Engine without getting banned (goes back to bypassing the anti-cheat) 3. Provide proof that, you have bypassed the anti-cheat and are able to change values within the game using cheat engine. I will provide a download, and website to where you can register for the game, when you get banned your hardware is also banned I would suggest using a virtual machine for testing, where you can easily change the IP address and your HWID.

We're looking for an electrical engineer to analyze a simple Digital Eyepiece: https://www.amazon.com/gp/product/B00X6IGXEU/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1 and reverse engineer it. Essentially, we need a diagram, and a PCB schematic/circuit board so that we can custom build this component. This is a pretty simple piece (a lens, and a small camera, with a USB attachment). We can ship/order this eyepiece to your address so you can work on it.

I am looking for someone to reverse engineer an old MMO about 10 years old called RF Online. I would like it reversed to the point where it's full source code and can be edited and recompiled at will. Please let me know what that would cost. Find out about the game on Google. It's a very old game with a fairly crappy engine called R2 Engine, which I am not sure what it came from, I think it's a hacked up version of Unreal2 Engine. Please apply if you think you can do this with timeframe it would take and price for the total project.

Tech Stuff 1. ASP.Net Web Forms, .Net 4.5, VB.Net 2. Expert at OOPS 3. EF, POCO, Custom ORM & LINQ, 4. Jquery, Javascript, CSS, TFS, Shelveset (Very important!!!), SQL Server 2014 5. Mid level SOA concepts. 6. MVC, Unity, IOC, Dependency Injection, Repository are all only nice to haves. They maybe used in other projects but not this project. Other skills & requirements & some general stuff. 1. Project: This is not very technically complex project. However the project specs or reqts are very weak. You will need to be able to follow previous sample/screens and then reverse engineer the specs, business rules to build new screens and functionality. There will be little technical help, and doubts takes days to get answered. This is a very large business complexity project. Do NOT apply if you have not handled real-time large business application. Coding will involve updating complex areas of the screen dynamically, with complex rules, business validations and most of it you will need to lookup other samples and work. Initial onboarding is for 2-3 days where you will need to work during USA CST day time, after that you can set your own 8 work-hour time. (lunch & other breaks not included). Must work in front of computer between 6AM to 9AM USA CST. Must give daily demo, and explain to code you have written, the progress made daily basis at 6-7AM CST. This is also one of the main reasons why you cannot use a Project Manager to facilitate communication and have a not-so-great english speaking SR developer work in the background. 2. English: Conversational level skills without heavy accent. You should be able to talk technical design with ease to me. You should be able to write clearly any technical problem you have explain the interface, pattern, logic and perfectly make sense in email. 3. Infrastructure: Reliable electricity, and solid Internet broadband connection is assumed. If you lost time during the day, then you must compensate it. I will strongly give importance to individuals, so if you are a company then sell me your candidate not your company. 4. Phone: You must have your phone on you at all times. I need your personal cell phone number, and expect you to pick it up. Period (see why below). 5. Availability: I do not plan to disturb you during your non work hours. Sometimes I just have to be able to reach you and wake you up at odd hours. This is why you need a laptop at home for emergency. Example--> Sometimes if client has a question or doubt and I definitely need to answer back, or if you do a bad code check-in at say 8AM CST and you have retired/resting for the rest of the day and the code is now breaking for the rest of the team. Then you have pretty much knocked out the entire team for the rest of the USA Day time. At this case I may call you at 10PM, or 1AM your time and request you to backup or fix or undo. Basically I am under the gun until this fix has happened, this is rare & not norm. There are 4 other USA based members working on this project. This is a good example of a blunder that is likely to get us fired or contract terminated. Sometimes I want you to be available during USA CST 7-9 PM so that I can go over some requirements, this too is a must! I understand your company's office may not be open yet, but this is again why you may need a laptop and a cell phone . 6. Time Ethics: This is simple, client is paying for stuff you know, not for stuff you need to learn/google/research. Already this project will take considerable time to study and reverse engineer business logic and it will be hard for us to explain to client, non-productivity, deviations. This is a full-time project, rarely we may need to discuss over phone during weekends. No, I don't need you to do free work, but at the same time if you need a couple of hours off during a weekday please make arrangements prior with me and you can substitute those over weekend/weekday. Client cannot monitor your work during USA National Holidays and so are unpaid. Your National Holidays , traditions and customs are all highly respected and I understand if you cannot work, such days are unpaid. If you decide to work on those days (*and it is a working day in USA) then those are paid hours. Any week's billable hours cannot be more than 40. Hours not worked in any day generally should be compensated within that week/weekend. Please don't plan any long vacations or time offs between now until year-end. Please do not send me a blanket generic written proposal or email, a short 10 minute well articulated proposal or email addressing some points and speaking to your strengths will help me. Project may start as soon as Sep 19 or 26.
