I'm primarily a freelance backend dev and for the first time venturing on full-stack development of a non-trivial web app on my own, hence I needed some guidance.

I've got all the backend stuff in php/mysql covered, I just want to know what's the best way to create a dashboard (with left sidebar) considering various aspects like long-term code maintenance and support, robustness, etc. Looks don't matter that much as it's a CRUD app but obviously, better is more appreciated.

Based on my research until now, AdminLTE seems to be the most popular way of doing it among most devs although a few others like material and coreui also seem to have some street cred.

But another approach I'm considering apart from AdminLTE is to just use pure bootstrap and fiddle up my own sidebar using something like this. That way, I won't be tied to just one Bootstrap version which is used by AdminLTE (v4.6) and troubleshooting will be much easier through google search and StackOverflow. What do you guys think is the right approach?

I’m a solo freelance programmer and want to write an app for internal project management, somewhere I can add projects, milestones, tasks, etc. and track them as I work on them, occasionally remind me of things like take a break, lunch time, etc. and over time I can track on which category I worked how many hours, etc.

I’m actually confused between whether to build this as a Web or Windows Desktop app. I’m considering latter because it can run efficiently on my laptop in the system tray using least memory and resources, web-based on the other hand will force me keep running an apache server too which will be an overhead (unless I host it on Google Cloud or someplace which might be an option?)

The only reason for considering web-based is that eventually I’m planning to make this tool open source and with web-based, many others can find this useful too (including OSX/Linux users). At that point, I may consider expanding its schema to include multi-user connectivity, client login, etc. but that’s going too far at this point!

The idea is that this tool should be useful not just for me but other freelancers, students, etc. who might be in my shoes. From that perspective, what do you think is the right technology to use? Web based or Windows based?

(I’ve extensively worked on C#/WinForms projects before and I’m thinking Visual Studio Express for desktop development. If web-based, it’ll be php/mysql based)

TLDR:

I need a website that let's signed in users vote on each others photos, and stores that data on who voted for what in a database.

Background

I run a facebook group of about 2,000 members. This group is designed for analog (any non-digital format) photographers to swap high quality artistic prints with each oter. The community was essentially dead and the admin wanted to throw in the towel so I took over. We've made progress, the group growth jumped by over 500% in the first month after I took over.

Right now trading prints doesn't work well. People make a post using the facebook selling format, and those who are interested comment with the image they'd like to trade for. The problem is that the posts get limited visibility due to facebook's algorithms, and stale posts hang around. All of this reduces over all activity, and the majority of posts don't end up in a trade.

My solution is to do a trade event with everyone participating at the same time. Since facebook doesn't lend itself to this I'd like to whip up a quick site for the event. My time is so limited these days I really don't have the capacity to build something from scratch, and the group certainly doesn't have any other developers to help out with it (it skews heavily on the older side).

I'd like to find an open source project that lets users sign in (sign in using facebook would be a bonus) and upload/vote on images. After the voting closes, I'll write code to pair everyone up in a way that optimizes for everyone getting to make a trade. If Alice votes for Bob's image, and Bob votes for Alice's image, they would get paired up to make the swap.

I feel okay writing the code to map out swaps, but I'm pretty terrible at web design and especially at front end design. I've looked across github, but I wanted to reach out and see if anyone could recommend something that I might of missed.

I don't expect to have 2,000 members participate, I think it may be as few as under 100, so hopefully I won't need to worry about scale.

Thanks in advance for the help!

My project involves reading text from a bunch of PDF form files for which I'm using PyPDF2 open source library. There is no issue in getting the text data as follows:

reader = PdfReader("data/test.pdf")
cnt = len(reader.pages)
print("reading pdf (%d pages)" % cnt)
page = reader.pages[cnt-1]
lines = page.extract_text().splitlines()
print("%d lines extracted..." % len(lines))

However, this text doesn't contain the checked statuses of the radio and checkboxes. I just get normal text (like "Yes No" for example) instead of these values.

I also tried the reader.get_fields() and reader.get_form_text_fields() methods as described in their documentation but they return empty values. I also tried reading it through annotations but no "/Annots" found on the page. When I open the PDF in a notepad++ to see its meta data, this is what I get:

%PDF-1.4
%²³´µ
%Generated by ExpertPdf v9.2.2

It appears to me that these checkboxes aren't usual form fields used in PDF but appear similar to HTML elements. Is there any way to extract these fields using python?

Hey y’all. Recently picked up a Cyberpower prebuilt. Looking to install a Linux distro on it for gaming. Currently have Ubuntu on my laptop, so I’m not a total noob, but my experience is still low. Not a big fan of having to use the terminal. Any distros y’all would recommend? Am leaning toward Pop_OS or SteamOS.
