Secure Multi-Tenant Print System Setup (CUPS/IPPS/Linux)

We are looking for an experienced Linux engineer to design and implement a secure, isolated print environment using CUPS. The goal is to build a lean, reliable system that delivers the required functionality without unnecessary complexity or ongoing maintenance overhead. Project Objectives The system should: Securely handle print jobs Support automatic printing for standard queues Allow manual release for sensitive jobs (e.g. finance) Enable safe re-routing of jobs if a printer is unavailable Ensure jobs are not retained longer than necessary Operate independently without affecting other services Key Requirement: Isolation A critical requirement is strict separation between environments: No visibility of other users’ printers or queues No access to other users’ print jobs No risk of jobs being sent to the wrong printer Strong access control and secure handling Technical Scope You will be responsible for: Setting up an isolated environment (VM preferred) Configuring CUPS with IPPS (TLS encryption) Creating hybrid queue logic (auto-print + hold/release) Implementing lightweight printer health checks Enabling manual fallback routing Applying security hardening and access controls Configuring automatic job cleanup policies Devices Printers include models similar to the following: Toshiba e-STUDIO Katun Arivia (All expected to support secure IPP/IPPS where possible.) Important Considerations We want to avoid: Overengineered solutions Complex custom scripting where not required High-maintenance or costly components We prefer: Native CUPS functionality Simple, predictable behaviour Low ongoing maintenance What We Expect Before full implementation, you should: Review the scope Recommend the most cost-effective and simplest architecture Identify anything that may increase time or complexity Suggest improvements where needed Deliverables Clear architecture outline Implementation of the agreed setup Documentation of configuration and approach Ideal Candidate Strong experience with Linux systems (AlmaLinux/RHEL-based) Hands-on experience with CUPS and IPP/IPPS Knowledge of secure system design and isolation Ability to deliver simple, practical solutions Experienced Linux engineer required to design and implement a secure, isolated print environment using CUPS/IPPS. Deliver a lean, reliable solution that securely handles print jobs, supports automatic printing for standard queues, provides hold-and-release for sensitive jobs, enables safe rerouting when printers are unavailable, and enforces timely job cleanup. Implement VM-based isolation, TLS-encrypted IPPS, hybrid queue logic, lightweight health checks, manual fallback routing, hardened access controls, and concise documentation. Recommend simplest cost-effective architecture and identify complexity risks. The ideal candidate has AlmaLinux/RHEL experience, strong CUPS and IPP/IPPS knowledge, and a focus on minimal maintenance and native functionality.

4 STL files to run analysis on Ansys Fluent for lift and drag

I would like someone to fix the issues on 4 STL files (created on SOLIDWORKS) which are parts of a Formula car to be able to use on Ansys Fluent Student to run lift and drag analysis. There are problems with the meshing on Ansys which I can't seem to fix in order to run analysis of lift and drag on student version. Therefore, meshing needs to be fixed on Ansys. If lift and drag analysis can be shown works on the files that would help. This needs to be on Ansys Fluent Student. Files can be sent once agreed on project.

Building database of owners by web scraping

I have been working with DeepSeek to extract data from the web site tuscasasrurales.com. The data I need is shown on the attached file Granada.png. Some of this data requires a link to be clicked as shown in the uploaded file Tuscasasrurales.png. Email addresses have to be obtained by visiting the website (if there is one). Where no data is available, leave blank. I have been trying to extract the data province by Spanish province. To get a list by province, enter the site and add the name of the province in the search box e.g Granada which returns 304 entries. Although DeepSeek was unable to get all the info I wanted it has given me a python script which will do the job. I have uploaded this. It does not include the fields Bedrooms and Bathrooms which I would also like included. Can you do this work and how much would you charge? There are initially 10 provinces with an average of +/- 200 entries in each. Thanks - Allan

Urgent OCR

In this folder are three folders called Bishopsgate archives, Newham archives and special collections and RIBA collections. https://www.dropbox.com/scl/fo/ixwakdbgdhodiq9sqlbk6/AAuJLgrYLb2WB1a--E_b76A?rlkey=y0f9poa3t1rpalmemh2qljs2n&st=dfvttlf8&dl=0. Ignore the folder called riba objects called scanning. Each of those three folders has many subfolders. For each of those subfolders perform these instructions OCR INSTRUCTIONS 1. One file per folder For each archive folder (e.g. TBUK1, NEWHAM2), create ONE plain text file (.txt). Put all documents from that folder into that one file. 2. Clear document separation and stable IDs Every time a new document starts, write: ============================== ARCHIVE_FOLDER: TBUK1 DOCUMENT_ID: TBUK1_01 DATE: (write date exactly as shown, or Unknown) PLACE: (write place exactly as shown, or Not stated) ------------------------------ Then paste the full OCR text of that document. For the next document: ============================== ARCHIVE_FOLDER: TBUK1 DOCUMENT_ID: TBUK1_02 DATE: PLACE: ------------------------------ Continue sequentially: TBUK1_03, TBUK1_04, etc. For a different folder (e.g. NEWHAM2): ARCHIVE_FOLDER: NEWHAM2 DOCUMENT_ID: NEWHAM2_01 Do not restart numbering without the folder prefix. If date or place is not visible: DATE: Unknown PLACE: Not stated Do NOT guess. 3. OCR rules * Copy text exactly as written. * Do NOT correct spelling or grammar. * Do NOT rewrite sentences. * Do NOT summarise. * Keep paragraph breaks. * Remove page numbers. * If a word cannot be read, write: [illegible] * Do not insert commentary. 4. Hand-drawn diagrams Do NOT attempt full OCR of technical drawings. Instead include: ============================== ARCHIVE_FOLDER: TBUK1 DOCUMENT_ID: TBUK1_XX DATE: PLACE: ------------------------------ HAND-DRAWN ENGINEERING DRAWING Title: (if visible) Location: (if visible) Company: (if visible) If no readable text at all: HAND-DRAWN ENGINEERING DRAWING (no readable text) Do NOT copy measurements or technical numbers from diagrams. 5. Save format * Save as .txt * Use UTF-8 encoding 6. For each subfolder also export one pdf for me to refer to easily - pdf must be under 30MB. You can use these Lower res versions of the subfolders for the pdfs. https://www.dropbox.com/scl/fo/hjed8pk08njhzfns6hhvb/ALP8N6HCGRHAuYwiJR_tEg4?rlkey=t4p5y3q3954monibbm2tktz90&st=lb5eo4lp&dl=0
