Reverse engineer check digit algorithm for barcode formula

I am looking for a highly capable freelancer to reverse engineer the check digit algorithm in a barcode formula. I will provide full details via PPH messages, however please be informed that me and my team have been stuck on this problem for a few weeks - it is not a simple solution following any traditional check digit alg such as UPC or EAN. It's possible the alg used is inspired by UPC/EAN, so I would like to work with someone with experience in check digit calculation and/or barcodes. I have a list of barcodes which work (i.e. have the correct check digit), however currently the only method to find the correct check digit is to test 0-9 manually which won't work long-term. Again, I will provide details if you are suited to the project. If a solution is found it can be delivered via code in any language or as pseudocode. Python is preferred. -- The proposed approach: I send full details of the formula including working examples The freelancer messages me if they find a solution I send the freelancer a few barcodes to apply their alg to and they respond with the check digit I test the barcode with the check digit to confirm it works I pay the freelancer The freelancer delivers the algorithm

Automated Student Feedback

Hope you're well! We’re a non-profit working with over 8,000 students across the UK, and we’re building a system to automate the marking and feedback process for student submissions on Google Classroom. The system will need to: - Download student work as PDFs from Google Classroom - Feed each submission into an AI model to generate feedback and a grade - Return that feedback to students - Flag harmful content for manual review - Highlight the top 10 submissions each week for staff review We’re currently exploring two possible approaches: - One using Google Classroom APIs and an online AI model (e.g. ChatGPT via API) - Another using browser automation (e.g. Python + Selenium) with a locally hosted AI model We’re open to suggestions on the best way forward and would love to hear your thoughts on what’s most technically viable and efficient. This is part of a wider effort to improve education and safeguarding — and while we’re a non-profit, we do have a solid budget set aside for this work. If this sounds like something you could support, please do get in touch. We'd love to hear how you'd approach it. Thanks! Kai.

Update my current bot

I have a bot that has been working for a while now. However, the situation has changed and I need to update the current bot (which has been using google chrome stealth (I think) along with a vpn) to create accounts on the site. The bot is written in Python and uses Selenium too The file for the bot to take the data from is an xls file. The bot currently records the password and the status of the attempt to create the account in the xls file I now need to change the bot so that it uses proxies, not the vpn. The bot should load the proxies the text file called "proxies.txt" that I supply. It would be useful if the bot loaded up the proxies from the proxy file each time we start the bot so that I can update the proxy list by replacing the contents of the proxy file. We also need to use an antidetect browser, and we need to choose android as the operating system, otherwise they detect this also. I can show you manually how we do this while you are logged in remotely, before you start. My anti-detect browser account has a limit to the number of profiles it stores. Please configure the bot to delete the contents of the folder in the antidetect browser control panel every 30 profiles so that we do not exceed the limit. Please let me know a price for completing this update to my current bot. We have had updates done in the past - if you know what you are doing this should only take a couple of hours. Cheapest quote will be contacted first. I expect the price to be lower than my budget amount. I have already been quoted the budget amount but the person is unreliable so posting here You need to be available during my hours, I am in the UK. You need to respond in a timely manner Thanks

Tabulated PDF to Word conversion and Arabic/English translation

Requirements of the contractor: - must be experienced in coding/programming. Specific Arabic language libraries is highly desirable - must be Arabic speaking in and able to review Arabic Fus'Ha including tashkeel Requirements of the project: All of the below must be met for payment since there are already online tools much cheaper than I'm paying here that do some of the below but not all. For full payment I can accept up to 5 errors a page For half payment I can accept up to 15 errors per page NOTE: where I mention Python or libraries below, this are just example. You can use any method you deem fit, as long as the product is delivered. Below are the original Arabic work and the English translation. You can start from the Authors preface. The footnotes would be different so use google translate to translate the footnotes not the English translation. Original Arabic word to be converted and translated: https://archive.org/details/AlIrshad_201712/%D8%A7%D9%84%D8%A5%D8%B1%D8%B4%D8%A7%D8%AF%20-%20%D8%A7%D9%84%D8%B4%D9%8A%D8%AE%20%D8%A7%D9%84%D9%85%D9%81%D9%8A%D8%AF%201/page/n3/mode/2up English Translation: https://archive.org/details/AlIrshad_201712/%D8%A7%D9%84%D8%A5%D8%B1%D8%B4%D8%A7%D8%AF%20-%20%D8%A7%D9%84%D8%B4%D9%8A%D8%AE%20%D8%A7%D9%84%D9%85%D9%81%D9%8A%D8%AF%201/page/n23/mode/2up All the below must be delivered: 1. Convert PDF to Clean Word Document: online tools have some errors when converting this so you would need to use coding to ensure accuracy, as standard converter tools have failed to maintain letter integrity, often replacing letters with shapes or symbols. 2. Font and Size: English text: Arial, size 11. Arabic text: Arial, size 15.5. 3. Document Split: Split the final output into separate Word documents each one having finishing on the 10th page e.g. first document 1-10, second document 11-20, third 21-30 and so on. This is instead of one large document which would make it slow to work on Google docs 4. Create a Two-Column Table: Place the original Arabic text in the right column and the English translation in the left column. 5. Alignment: Ensure Arabic text is right-to-left aligned. 7. Add Tashkeel to the Arabic Text: for example utilize a Python library or function to add tashkeel to the Arabic text. 8. Intelligent Sentence Splitting: Split the text into 1 or 2 sentences per cell using an Arabic-specific NLP library rather than splitting by commas or fullstops. For example libraries like camel-tools can tokenize Arabic sentences while respecting linguistic boundaries (e.g., keeping “bihaa” with its associated words). 9. Sentence matching: Ensure Arabic sentences of each cell are matching the correct English translation sentence. This will require some work since the English translation may either omit a sentence completely or give a completely different meaning than the literal meaning. Where completely omitted the English cell can state "sentence omitted" or meaning is altered significantly this can stay in the cell but a comment explain this. 10. Quality Expectations: The majority of the tashkeel, sentence splitting, and translation must be accurate, with no more errors than what is specified above. Trial the process on 1-3 pages first and submit for quality check before proceeding further. The final output must maintain high quality across all pages. Random checks will be conducted to ensure quality.
