Need some help please with web related matters since I don't know much about web (more on the software side of things).
Basically, I am developing an iphone app and would like to send data to a local server once in a while (for simplicity, let's just say I want to send this info to my personal computer which will act as the server). This is just some simple data, and I dont care about the format (actually .txt is the best, but I am open to any format which will make it easier - I am just transferring numbers).
What would be the best way to go about this process? A quick step by step explanation would be highly appreciated. From my very basic knowledge I assume that I will need to:
setup my Mac as a server (which I think should be done from settings?)
Create a URL connection on my app and send the file?
I am probably missing 50 other steps here...
Thanks!
One path is to set up a webDAV server -- you'll have to Google that up, it's far too big a topic to cover here.
To the specific questions you asked:
1) Your mac can become a web server by turning on the WebSharing in preferences, or a file server by turing on fileSharing. Be sure to set permissions the way you want them.
2) If your mac is a web server, you could write a simple CGI script (perl, ruby, or the like -- this is simple tutorial stuff that's all over the www) that accepts your text as a parameter. From your iPhone app, you'd make an NSURLRequest to a URL similar to:
http://192.168.10.1/webPage.html?this+is+the+text+I+want+to+send
Of course, you can get fancier ans use POST requests (the above example is a GET request), but that's going to require more reading.
If you want to transfer files via file sharing, that's a bit more complicted.
What would REALLY help us answer is if you could specify the question a bit more tightly. As it is, you've asked about a very broad area that covers quite a bit of ground.

I'm using swift — and the app needs to send a photo and matching text (that a user submits) to a server so that I can download the photo/text.
Would an existing FTP server that I have setup for my website be possible for this application? Or would it make more sense to do something with a web portal?
During my research, I'm finding options like Backendless, Alamofire, Gold Racoon, and various others. They seem like overkill for the simple task I'm looking to accomplish. Is there some minimal service out there that can automate my simple need? If not, which of these options would you recommend for my situation?
Ideally the setup would be free, but I'd be willing to spend up to $100 or $10/month if the service fits.
I'm new to app development so I'm feeling overwhelmed with the options and not sure how to begin researching. I hope beginner questions aren't frowned upon here — I would really appreciate any advise on what I should begin learning to achieve my goal of sending a photo+text from an iOS app to a place where I can access them.
If there are other questions I should be asking to achieve this, please let me know.
For your case there are two main routes to consider
1. BYOS (Bring Your Own Server)
With this option, you are responsible for creating and maintenance of your own server.
Now you can use various services such as Digital Ocean and Amazon for this.
On top of this, you would be responsible for creating your own database and maintaining it as well. Plus, you would need to write server side code along with client side code (the app) in order to instantiate communication between the two.
The advantage of this is that you virtually have control of everything but I think it is pretty clear how painful this task is.
2: BAS (Backend As a Service) Highly recommended
With this route, you simply have to write the app and let another service handle the server side of things. One of the most common ones is Firebase. Most folks including startups go down this route.
There are a bunch of other services out there.
Two Cents:
Whatever option or service you decide to use, I would recommend you make sure that:
a. The service has a good track record.
You do not want something that might end up getting shutdown in the next couple months. I know it is hard to predict this but certain initial guesses/probabilities can be made.
b. Make sure its community is vibrant.
The last thing you as a newbie wants is to be stuck and have no one to help you. Research around and see the different questions people ask and whether or not answers exist.
I'm creating an app which generates a random question from a list (currently stored as a Numbers doc). Once that question is answered by the user, the unique question ID, the question itself and their answer is stored in core data.
When the user requests a new question one will be generated randomly from the original document and it will then be cross referenced with core data to find out if the user has previous answered that question.
I haven't included the code of my app at the moment as I'm not really looking for specific coding help. As someone who is new to the world of code I'm just looking for a nudge in the right direction for me to go and do more studying.
JSON looks like a possible, but the more I read about that the more it seems that it is about an app communicating with a website. I don't really want the questions to be accessed by just anyone, so putting them on my website might not work? Could I do it with a file local in the app? maybe a CSV?
I'm anticipating the file may become quite big as I add more questions - so I'm not sure if that changes things?
Thanks so much in advance, and apologies if this isn't quite the right way to ask questions on here.

There are many options to solve your problem. Each option depends on your skill, time and if the solution is even necessary for the app you want to make. In the end it's you who decides on which solution solves your problem. There are a few options:
creating your own backend
have a local file in your app
or use a third party service like Firebase.
Each option has its own benefits. Just to list a few:
Local file:
You could have a local file in nearly any format (XML, JSON, .plist) etc. The downside is that your app isn't dynamic - you have to manually keep adding text to this file and update your app trough the App Store for your users to see these changes. If you're going with this approach, I'd recommend using a .plist or a JSON file which is saved in your project. How to implement this correctly is beyond the scope of the question, but there are plenty tutorials out there to help you getting started.
You could put your data in a .plist file. This is nothing more than a dictionary with key-value data (same principle as JSON where each key has a value). An example:
question1 is the key, of type String, containing the value "How are you today". It's easy to read from this .plist since it's the same principle as JSON.
Also, JSON is just a format, it's used often to communicate with websites, but it's not limited to sites only.
Custom backend
This means that you make a backend on which your app can communicate with. You'd have to host your backend, write logic / code on your backend and so on. This can be very time consuming, especially if your app isn't that big/demanding. I wouldn't recommend this unless you have the experience, time, patience and need for this solution.
Third party
This can be a nice solution. Using a third party service like Firebase means that you have your data online. The Firebase library has been well tested and has great documentation to get you started. It's secure, fast, simple but .. it does take a little bit of time to learn how it works - but the end result is that you have a dynamic app where you can add, delete, edit questions and so on. This data can be protected if you wish - which means only authenticated users can access this data (Nobody else will be spying on your data :))
I don't really want the questions to be accessed by just anyone, so
putting them on my website might not work?
Read custom backend and Third Party.
Could I do it with a file local in the app?
Yes. Read Local file.
maybe a CSV?
That's possible but I wouldn't recommend it, but that's a personal opinion. I find it outdated and it's more difficult to work with than JSON.
I'm anticipating the file may become quite big as I add more questions
- so I'm not sure if that changes things?
What is a big file? Nowadays reading a "big" JSON file is probably nothing more than a few MB at most. Your phone reads this in no time. This won't be an issue for your phone or app.
Just looking for some help/suggestions with this. I require my own server for an upcoming project that will be hosting users websites. I want to build a control panel the user can log into and modify their website which will be stored elsewhere on the server. This all seems easy enough, It's just managing domains and emails that confuse me.
What should I look for to manage domain names and point them to the correct website and also what would be the best way to manage email accounts/set up new ones etc. I want to avoid cPanel/WHM if possible, I'm looking to control most things through the control panel I will be building. So any suggestions on this would be useful as well, as I will be wanting to add email accounts through php (Can be done using a shell I assume?).
I will also be wanting to measure bandwidth used on the websites contained in each users directory, any suggestions on making this possible?
I'm really looking for some suggestions on what software to use to set this up, any advice would be really helpful!
Thanks,
Graeme
It sounds like you've got a lot of creative room. May I suggest a web framework? Django. With it you can build out a nice control panel, it's template system is clean and concise. It's also based on Python and thats why I suggest it. If there is a python module for it, you can use it in Django... so things like altering, creating, etc. local data/files is a breeze. you simply us Python (you can even forget it's "django"), crunch your data and then spit it out (into django... out to templates.. to display to the user).
You'll likely want AJAXY biznazz, their is a nice Django App for that, Dajax. Django has a rich and helpful community and tons of resources. Just hop on GitHub.com and search for Django, You'll find tons of stuff.
Im building a DNS Control Panel with it. Which sounds like a minimal version of what you're doing.
I've searched the web for this bit to no avail - I Hope some one can point me in the right direction. I'm happy to look things up, but its knowing where to start.
I am creating an iPhone app which takes content updates from a webserver and will also push feedback there. Whilst the content is obviously available via the app, I don't want the source address to be discovered and published my some unhelpful person so that it all becomes freely available.
I'm therefore looking at placing it in a mySQL database and possibly writing some PHP routines to provide access to my http(s) requests. That's all pretty new to me but I can probably do it. However, I'm not sure where to start with the security question. Something simple and straightforward would be great. Also, any guidance on whether to stick with the XML parser I currently have or to switch to JSON would be much appreciated.
The content consists of straightforward data but also html and images.
Doing exactly what you want (prevent users from 'unauthorized' apps to get access to this data') is rather difficult because at the end of the day, any access codes and/or URLs will be stored in your app for someone to dig up and exploit.
If you can, consider authenticating against the USER not the App. So that even if there is a 3rd party app created that can access this data from where ever you store it, you can still disable it on a per-user basis.
Like everything in the field of Information Security, you have to consider the cost-benefit. You need to weigh-up the value of your data vs. the cost of your security both in terms of actual development cost and the cost of protecting it as well as the cost of inconveniencing users to the point that you can't sell your data at all.
Good luck!
I am administrating a small, private website with 100% trusted users (about 60 people, i know them all personally).
I am having many problems with the PHP based upload system i have in place currently, mainly with users encountering timeout errors and other varying issues due to the way the upload is handled (not to mention the complete deadzone in the UI created by making the user stare blindly at the page until the upload finishes
Anyways, i have been tossing around alternative forms of file uploading i could offer. FTP accounts were nixed due to the level of tech savvy required. Flash/Java uploaders were nixed because i don't really want proprietary third party applets running on my site.
The other idea i came up with that i think would be perfect would be to offer the ability to EMAIL the files to the server. Emailing attachments is a simple enough task, and better yet it provides the user with some tangible feedback to the uploading process.
My question is, how could i go about implementing such a system?
The server is running Gentoo Linux with Apache and i have full root access. Mail dameons can be installed to my needs.
If you have a better way to upload files, perhaps you could offer that instead?
Stick with PHP. It's certainly not perfect but the problems you're describing can probably be handled. max-execution-time and upload_max_filesize are configurable values. I would at least try tweaking those numbers (no php code changes required) before trying to implement an email based solution.
There are several file upload libraries with progress bars using pure javascript. Keep it in PHP.
