Development related, but not a development question:
I want to write a mobile app that will require a database and also use the device's realtime GPS location. I could write it easily as a C# WinForms app, using a SQL server that I managed, but am having trouble deciding on the tech to use for mobile development. And honestly, I just want to get coding.
Should I build it out this way first, then try to convert it over to a mobile app, even ditching C# for java or c? -(I know Java, I would be willing to learn C) Or is it not worth it to hash out a proof of concept to get the logic down first?
Secondly, what are my database hosting options, any speaking from experience? I have experience with SQL and some with CouchDB. I have no problem moving over to NoSQL for this, too.
Open to any most input.
[PS] Not really open to Mono. License is a little pricey, and I'm partially doing this project for future job prospects, of which I see less and less for Mono.
Heard of Xamarin? You write in C#, and it compiles to native code for different mobile platforms. I remember it being a bit pricey though (never used it myself).
As far as the DB, looking for a DB that resides on the device, or one that is accessed over a network? I think iOS comes with some DB (I could be wrong about that), and you can use SQL Azure if you want to use one over a network.
Probably. Looking for a smart phone now to replace my Samsung Rugby 2. Finally got text messaging. Bit behind the times I know. Back when I was getting spam, and they would not reverse the charges, so I blocked text messages.
In India, call rates are cheaper than SMS. And now with 4G & chat Apps lining up, people hardly use SMS. The only time I use SMS is when I'm driving. I mean - " I am driving, I will call you later". The auto-call-reject thing.
Starting to think people post kid pics in their profiles because that was the last time they were cute - Jeremy.
Who actually cares about the resolution of the camera? Very, very few people at this point because cameras in phones are good enough. And if you care that much about resolution you will use a real camera. In fact, the higher resolution now means that storage may become an issue. Further, by going overboard with the camera they've made the camera the focus (sorry) instead of the phone, the apps, the connectivity with the world. It's bulky and it won't sit flat, and I struggle to see this as a desirable (from a mass market point of view) item.
Resolution isn't the killer app anymore. It's ISO and grain, and with the 1020 only going to 3200 (the same as the iPhonw 5) it's not enough of a differentiator. Image stabilisation obviously increases the effective ISO, but still, I'd rather they put the effort into ISO 12,800 or even 25K so that pics out at night look great, rather than have 41Mp of grain when you take your indoor pics.
Actually, although folks on this thread are right that you get better image quality because of oversampling, the bigger (and significant) advantage is that having higher resolution gives you the equivalent of optical zoom. A 3 megapixel camera with a 4x optical zoom captures the same pixels (actually fewer) of the target than the portion of the 41 megapixel Lumia 1020 picture over that target.
Agreed that ISO is important. But the point here isn't so much that we can see things at an impossibly fine grained detail, but that, even after the fact, we can zoom in without seeing the pixels.
Chris ... I initially thought the same thing when the Nokia 808 came out under Symbian with this camera on it. But a little research into that camera reveals that Nokia may be onto something. Quite simply from what I've seen, it takes stunning images for a phone. It can do a very effective "digital" zoom and by using their pixel 'binning' technique the images are like an effective 5 meg cam in size. i.e quite manageable.
I feel Nokia are being quite innovative here and I really don't think the phone should be dismissed so easily. Yes perhaps a little bulky but it will mean I hopefully can have a reasonably high quality cam with me at all times rather than lugging around my Nikon D600 kit with it's array of lenses.
The only pity (for me) is that it does not have a 1920 x 1080 screen or better nor a micro SD card slot but I can live without those.
I'm taking my patience pills while I wait down here in Oz for the beast to turn up on our shelves and as you would know Chris, that can take far too long
I'll admit that I was reading the article I saw on the 1020 while deploying some scary code so I was definitely distracted. 5Mp is definitely manageable, and fefectively having a digital zoom is definitely nice.
However, until they can come up with a decent mathod of letting you adjust the f-stop to control the depth of field I'll stick to my D60
