I am looking for a way to do real-time tracking of multiple vehicles (with iphones) at a time.
Instamapper is close to what I need - I can install the app to run in the background of driver IOS devices and then capture the GPS through the instamapper API. However, the updates are not quick enough - only 1 every 10 seconds. I believe I would like to sample one time per second or more.
I ran across this today - http://www.vworkapp.com/ - It is a paid app, looks interesting, although I was concerned because there did not seem to be many existing customers using the product based on the app store reviews.
I like Glympse for my personal use, but they do not have an API yet.
Any suggestions on existing IOS products that accomplish this functionality? If not, any source code that is close so I can make required tweaks?
It's not likely that you really need that much info about vehicles other than your own.
Most apps which show movement in maps interpolate between points of much coarser data. This is why your car often appears to go the right direction for a moment, even if you go the wrong way when following GPS. Movement displayed is predicted by previous data, and corrected when new data contradicts predictions.
Go ahead and update your own device a bunch, cause the battery drain is your only factor to consider. For everyone else, calculate velocity (that's speed and direction together), and use it to update your info on their vehicles smoothly.

Looking to know which is easier and faster to implement in order to send out push notifications. This is going from start(account creating) to finish(releasing to app store).
Anyone had any experience with both or one?
thanks
I'm Matt from Parse. Push is arguably one of the most complicated features to add to an iOS application and we spend a lot of our time making this process as easy as possible for you. We have a great tutorial on getting the right certificates setup and an in depth Push Guide to help you get started with our API.
Our pricing model is straight forward (you pay for the number of pushes you sent and the first million per month are free) and we have some really cool features. You can use 'channels' to send pushes to predefined segments of your users or make use of our data storage features to push to really targeted and dynamic segments of your users. With the second option you can basically save any data you want (user's location, age, interest, etc) and writes queries to target exactly the segment you are trying to reach.
Combined with our new Push Console, you don't need any technical skills to send these notifications later.
I know I may be biased since I work at Parse, but as an iOS developer myself I think you'll be delighted by our super easy to use API. We've spent countless hours crafting an API that would be easy to use and familiar to iOS developers.
If you have any questions, send us any questions at feedback#parse.com.
Each service has it's pro's and con's. It would be in your best interest to read the documentation on both and make your own decision.

I'm a beginner of iOS app development,
I'm working on a very small project to show useful info of another app
i simply want it to check the out/ingoing packets through my device and find a specific packet where its string contains a specific word, if found then show the whole packet content,
is it possible to be done and does apple allow tracking packets ? thanks in advance
Regardless of it being possible or not (I'm guessing the answer is no, since you probably need root access and more low level APIs that aren't available by default), you want to track other applications. More specifically the network activity of these applications. This imposes several 'difficulties';
Given their policies, Apple will not allow this.
Your application will need to be active on the foreground, while background activity of applications is limited. The number of packets you will be able to 'sniff' will be very minimal and if you chose to put your application in the background instead your time will be limited to about 10 minutes of execution time.
My advice? Don't. Unless you are interested in the jailbreak 'market'.

What to do when there is a task in the code-compile-debug cycle during which only the computer is working?
With embedded development such task is Downloading the hex to flash, also compiling. It takes somewhat less than a minute, but feels extremely boring when you have to do it several times in half an hour. How to spend the time so that I wouldn't loose the problem/program from my head, but also wouldn't feel bored waiting?
Multitask. Either start working on the next module of code while testing the last, or answer emails, read datasheets, etc. If you get the opportunity to work on team developing a chip you can easily end up with 30-45 minute simulations. Sometimes you spend that time wading through the waveforms from the prior sim, but sometimes the thing you were looking for in the prior sim takes only a few minutes and you realize what you have to do for the next sim.
Basically be able to multitask, work two or three problems or modules of code at the same time, while waiting for one to execute a test, be coding the other one or few.
Another answer may depend on where this embedded code is going, usually embedded code needs/wants to be more robust, more reliable, than normal applications. So you could spend that time carefully verifying that your code is doing exactly what it is supposed to, even though you are pretty sure you know where all the bits are in a register, go back to the datasheet for that peripheral and verify you have put the correct bits in the correct place, and the datasheet doesnt have comments like you must leave this bit as found (in this example a read-modify-write is required instead of a simple write).

I develop applications on both IPhone and Android. As a part of my organization's Technical Session program I have myself delivering the next session on iPhone or Android. Getting the session made me start comparing both technologies, which believe me, is really a tough job. As a programmer in both technologies I often think how will the Application seem to be if I used the other one. Which further makes me list out pros and cons of both.
Android ahead of iPhone:
There are couple of factors where Android steps ahead of iPhone.
Multiple apps at same time
Information visible on home screen
Better notifications
Hardware flexibility
iPhone ahead of Android:
Following are the factors:
UI Smoothness and Consistency
Language support
Accessibility options
Battery life
Resource efficiency
Hardware quality
Better App Store
However, as a programmer, I want my session to be more of technical rather than a being a general overview of both technologies. For which I need some help. For instance Android's memory management is way ahead of that of iPhone's. On the other hand IPhone's UI has no comparison at all.
What more (technical) points can I include in my session? Also, kindly correct me if I am wrong somewhere above.
As far as the UI goes. I'm interested (as a programmer) to understand why exactly you consider iOS to be superior because in android the layouts that can be used are ever expanding and can be customized from the ground up where as in iPhone if you step outside of Apples box you get booted from the app store.

I am guiding an intern in learning iPhone development.
I need to give him a sample project or I can say an app as part of his project work.
Please suggest some ideas.
Keypoints:
1. It should be a project for which the requirements data can be easily searched on Internet.
2. It should be a 20 days project.
How about an app that given a current geolocation, position, it fetches all stores, bars, restaurants, etc. Using a RESTful API, like simplegeo, google places or cityserch. And annotated a map view. For each pin replace the image with category based icon and annotate the name of the location.
The Stanford iPhone development course once offered a pretty substantial mid-term project to its students, the Paparazzi, http://www.stanford.edu/class/cs193p/cgi-bin/drupal/downloads-2010-winter .
I suggest you take a look at the Paparazzi 1-4 pdf files. It seems it perfectly meets your needs, (1) Flickr data can be easily accessed on the internet, (2) it is pretty substantial and therefore requires quite a few weeks work, (3) It is meant to be help the student learn the skills along the way, therefore is easy at the beginning and gets harder and harder when the student wants to further polish their work.
