Quick and dirty secure file share web app

Pretty simple, I need a web based app with 2 sides to it. My side where I upload a file (or multiple files) and once the file is uploaded, a share link and password is generated. On the customer side, the link takes the customer to a page where they enter the password. If the right password is entered, they're presented with a page where they can view and download the files which I uploaded. A few further details: -The upload page will ask for an email address and name of the customer -Upon uploading the files, the custopmer's name, email address, uploaded file names, share link, password and date & time of upload is added to a DB -When the customer downloads a file, the date & time of the download is added to the DB -Magic word is "honeybee" -App will be installed on fileshare.mydomain.com -Customer download page with password entry will be download.mydomain.com/link -You must include a header at the top of the download/customer page with room for my company name and logo -A login system to fileshare.mydomain.com is not required. I will create the subdomains and DB and I will provide you with FTP and phpMyAdmin access. All files and code must run from my server, there must be no external files/code that the app is depedent upon.

Do not use ChatGPT or any other AI platform to generate your response/proposal, I will ignore it. Delivery is expected within 4 days. Budget is £25. The app doesn't need to look great, it just needs to work.

Updating PHP website

We have a commercial website for our gallery where we sell original Japanese prints. The website was made a long time ago in a very old version of PHP, which is no longer supported. This causes issues with security making the website is difficult to access, and recently we have become unable to upload images for new products. We want to update the website to a newer version of PHP that will meet current security standards, and allow us to upload products again. We are also currently paying for a service called "VPS" which is needed to keep the site running, but ideally we would like to avoid using this if it isn't necessary once the website is up to date. Here is the link to the website: www.japanesegallery.co.uk/default.php

BUSINESS GRANTS SPECIALIST

Looking for a genuine business grants consultant who can help my new alcohol brand ltd company which is launching in the next 3 months secure as much funding as possible via grants. Happy to do various different deals depending on what you can help to secure. If you can help to secure finance with GRANTS, you could make commission from the grants such as 30% in exchange for securing this funding. If you can get interest free business loans, or government backed business loans, depending on what is secured and achieved, we can work something out. Grants, obviously, are much more valuable and do not need to be repaid so you could make a nice chunk of commission if you can help to generate successful outcomes for a genuine new small business launching soon that I could not secure independently. If you have experience working for a ltd company and have successfully secured business grants on their behalf then you would have priority. Someone with experience who knows exactly what's needed to generate results, if this is you, get in touch. The company could expand into international markets over time, so if you have experience securing grants in our country should the brand expand, then again, let me know. UK based applications will have priority, but if I know that there's the possibility to secure a large grant in exchange for bringing business operations to a new region, of course, this will influence operational decisions moving forwards.

Need a userspace replacement for linux namespaces and bwrap.

Currently, flatpak and steam clients for ubuntu require namespaces to function properly. This limits the ability to run them on minimal/limited hosts such as docker containers. We require a seamless drop-in replacement that would mimic namespaces behavior without the corresponding kernel modules to circumvent this limitation. While we are aware that this has some serious security risk implications, maintaining some level of security guarantees that namespaces provide, to the extent that's applicable in this context, should be still possible on userspace level. There are no requirements for programming languages or frameworks, but we suspect lower level solutions like c++ will offer better performance in this case. As such, applicants that can offer their experience with those will be given priority.
