I'm pretty new to everything related to hardware.
I am searching for a way to connect PWA to POS hardware, like Scanner or cash drawer. How can I access these via PWA or JavaScript?
The hardware you intend to use need to use webUSB api (for e.g. "Canon DR-M160II scanner" uses one), which will of course depend on the implementation by the hardware vendor.
You can either check if there's any compatible hardware already available and then for coding your PWA accordingly, you can refer to this web.dev article.
If you strictly need to use the existing hardware and can get the corresponding hardware vendor to customize it, you can ask them to refer to this article on web.dev.

I'm trying to build a swift app that would allow a user on one side to draw an image that will be updated in nearly real time on the other user's device, somewhat as if they were drawing on a whiteboard in person.
Anyone have any tips or places where I should start? I'm relatively new to swift. Thanks for your help.
This requires a persistent line of communication between your mobile device(s) and your server. Websockets allow this type of communication. I haven't implemented them myself so I can't provide implementation details, but there are plenty of resources available online.

I think Realm is exactly what you are looking for.

I am thinking the build my own home system that can do basic tuning channels or view lineup for my Comcast cable TV, like xfinity TV App does.
I am wondering if someone know Comcast open their API? or is there a way that can do it?
Thanks
Lewis
Most likely, you'll have to program against a 3rd party system that uses a CableCard.
To my knowledge the only way you can do something like this is to write a plug-in for Media Center on Windows with a CableCARD. Take a look at the Windows Media Center SDK Overview and see if it has the functionality you're looking for.
Nope, everything I've seen suggests that it's a private API. Which makes sense, they probably want you to have to use their services instead of creating your own.

I'm currently doing an internship in a medical laboratory
They want to buy Ipad and medical device connected to it
example: diabet tester http://www.ibgstar.us/
blood pressure monitoring system http://www.ihealth99.com/
I'm wondering if I can code my own application that gets the data from the medical device and then handle it?
thks for your answers
I think they're some step to success it .
At first you need a Hardware solution like said "Mundi".
You need to grab data from device and store them somewhere accessible (like in a BDD with online acces).
And then the iPad application just have to connecte to the data-Source and play with it
The short answer is YES.
There are many ways to get the data into the app via a network. If you would like to read from the device directly, you would have to additionally find a hardware solution.
I'm not sure this applies, but I've seen some really cool medical apps written using Harvard's SMART project. They provide a simple but effective framework, which is independent of the Hospital Information System (like Cerner, Epic, VistA).

I want to developed iphone application in which i want to track another iphone on google map with in 10km region what kind of API can i use please tell me
Thanks
You'll need the device you're tracking to tell you its position. That means that it'll have to be running some app (possibly the same app) to get its position using Core Location. Then, it'll have to provide that information. As Richard Ross points out in his comment, you could do that using GameKit. Another approach would be to have the device send its location to a server that you create, perhaps using a web service. Your device would then query the server to find out the location(s) of device(s) it cares about.

Watching their video and browsing their site, it looks like I have to do some kind of mouse olympics to publish an app. I want to publish an app to the App Store for as little money as possible, without using "hacks". Is there any way to do this, and does Apple allow it?
They seem to have posted the names of several apps using their SDK, and apps in the App store are required to include developer contact info. Write a few of the developers of recent apps using their toolchain, and see if any of their replies give you enough confidence.
