Back from Voices that matter: iPhone developer conference

Reading Time: 3 minutes

#VTM_iPhone

The conference was hold in Philadelphia, PA. Note there was a VTM_iPhone conference this past spring in Seattle. This is my first time attending an Apple themed conference, my first time to hear names like Omni Group, Mike Lee, which are almost like household names in Mac/iOS community.

Ok, let me get to the topic, the people and topics of conference. First I want to thank Chuck and Barbara (and all other Pearson Publishing organizers, venue helpers) for their hard work on logistics (food, drink, website etc.), if there is anything could be improved, I think it’s the Wifi access point. Probably due to the overwhelming of iPhone/iPad, and laptop, sometimes we had difficulty connecting to Wifi. But that’s a minor thing, compared the quality of speakers, and the openness atmosphere of participants (Mac community is much friendly than some of the other dev community as I know of).

Technical sessions are excellent, sometimes I had hard time to make a choice but I like to attend all 3 sessions running at the same time. Eventually I decided to take more UI (user interface) and Graphics Design classes as that is my weakness, coming from coder/programmer background and not graphics Q. Here is the schedule of classes. Some of the highlights: Aaron Hillegass talked about the product cycle and going form “independence to interdependence” as business grow. Not entirely new topic, but good reminder to me. Mike Lee reminds me a Chinese guy names Lu Xun (after I gave it more thought): he fired at a lot of places and I think many of his points are valid criticism of “lack of effort/thoughts” in design. I think yesterday Steve Jobs’ fire at Android fragmentation is along the same line. When “Open” is just for business and marketing purpose, how meaningful really is open of Android?

At philadelphia voice that matters iOS conference

Reading Time: < 1 minute

I am at Philadelphia now. I came here for the VTM iOS conference. Took southwest Air from STL this evening, arrived phl slightly after 10. Planned taking the shuttle, but could not reach the guy per his instruction. Took train to market east/Philly conference center , then called a taxi to hotel. Saw quite some people on street on the way to society hill Sheraton. It seems free AT&T wifi only works on my iPhone, not MacBook. So I settle on iPhone for tomorrow conference info and how to get there.

I also wrote this post via wordpress iPhone app. It requires wp 2.9 but my Stlplace blog was still at 2.0.2 🙁

Oh, by the way, it seems apple fixed myNestEgg app update (1.1) stuck in “upload received” status. It’s in “wait fore review” mode now. This update will fix some of the bugs.

iPhone iOS dev blogs

Reading Time: 2 minutes

The following are iPhone development blogs I often read. Note I used Google reader to get them. I also listed some of the blogs under “dev” category in the side bar (small).

Technical
iPhone development by Jeff Lamarche. Jeff is the author of the best beginners book for iPhone dev “Beginning iPhone development”. Recently I found his profile at LinkedIn, and found he was a law school graduate, which is total surprise to me. He is definitely not a lawyer type in terms of writing (blog) and talking style (from his tweets).

Cocoanetics (aka Dr. Touch): Oliver Drobnik, the former Windows Admin turned full time iPhone iOS developer lives in Austria (Europe). Note he recently changed the name from Dr. Touch to Cocoanetics. Regardless the name change, I found he has a very good sense of both technology and business: I think his article on Notifications and “Part Store” (he sold his components software like parts) are very interesting.

iPhone developer:tips written primarily by John Muchow, who is the author of Core J2ME (which is the primary mobile development language pre iPhone, it is still used on Blackberry platform, and note Android used a different Java virtual machine developed by Google). I think some article such as “rename Xcode project”, “Prevent application being placed in background” etc. to be interesting.

iPhone development blog: written by Nick Dalton who got into iPhone dev early. A lot of goodies include this iPhone iOS app store reject reasons. I believe he is a co-founder and CTO of a mobile development firm in SF (can not recall the company name on top of my head, you may google).

Ray Wenderlich: the blog bears the author’s name. It has a lot of meaningful tutorials (not those “Hello world” stuff). Besides that, I found this How to host beta test for iOS app” to be interesting.

Other Resources, news, gossips etc
iPhone developer news (Apple): get it from Apple iOS developer center. The official place for all the announcement etc.

Mobile Orchard: used to be good technical stuff, stopped update this April, just resumed blogging.

43 iPhone app development resources: the list is a bit dated, but still useful.

I will add more as time goes.

Submitted 2nd iPhone iOS app collegeFund ~ college savings calculator

Reading Time: 2 minutes

(Update 10-26-2010) I forgot to mention that app is available at iTunes App store since Oct 5. The product support page is at uudaddy. Sorry for my omission 🙂

(Original) I submit the collegeFund app 3 days ago. This app is similar to the myNestEgg ~ the retirement calculator, it helps parents (and other family members who are willing to help) to calculate the kid’s college savings fund vs. the retirement fund in the retirement calculator.

I got this idea more than a year ago when a close friend who is sending kid to college. I can felt financial burden of the father, while I can also fully appreciate the kid’s decision to go to a well known college instead of the college his dad and yours truly both went (btw, the job prospect of our alma mater was very good).

This March, our daughter was born, I was hoping I don’t have to be put into such as tough spot when my kid starts college (btw, her father will have to seriously think about the retirement plans then). Hence, I opened the Ohio 529 plan a month after her birth, and started to put away the money we received from family. Meanwhile, I set an automatic monthly deposit for her account.

CF_currentSaving0_age0_annual5000

Anyway, I wish this is a beginning for parents, grand parents, uncles, aunties etc. to plan for their kids’ college education. Now let’s hope the app gets approved soon 🙂

My first week impression of iPhone 4

Reading Time: 2 minutes

Graphics is very sharp
This can be demonstrated by the Netflix app. I installed it the first night right after I got home. Watched a movie, the graphics quality is very very good.

Installed apps
Besides Netflix and other usual stuff (google, twitter, facebook, linkedIn), I also installed NFL Score, Public Radio Tuner (a bit disappointed on this one, not multitasking enabled, so I can not read email and listen to the radio at the same time), Yahoo, iBooks, myWireless (AT&T), WSJ and VTT (Virtual Table Tennis) Lite.

fstream: this little program allows me to listen to Chinese radios via Stream, and it is multitasking enabled (can run in background). The only caveat is it eats the data limit in 2gb data plan fast, more later.

Weakness
Battery: per Apple iPhone battery page
“iPhone 4 offers up to 7 hours of talk time on 3G, 14 hours of talk time on 2G, 6 hours of Internet use on 3G, 10 hours of Internet use on Wi-Fi, 10 hours of video playback, or 40 hours of audio playback on a full charge at original capacity. In addition, iPhone 4 features up to 300 hours of standby time.”

This is about right, as I had to charge my iPhone 4 in the afternoon couple times (early in the week) as I was listening to the Internet radio.

So so speaker-phone? I had this feeling when I talked to my friend this evening.

AT&T Data plan
I picked the common 2gb plan. 2gb is a bit tight for me, I used 425 mega bytes as of day 3. Why? Because I was using this fstream app listening to Chinese radio stations. It’s cool, but it’s also a data hogger: for 64 k per second stream, it’s using about 25 mb in one hour per SuperUser. For the time being, I am using the following approach to relieve the data usage.

Why I created myNestEgg retirement calculator app?

Reading Time: < 1 minute

More Q&A about myNestEgg ~ the retirement calculator app

1. Why do you create yet another retirement calculator app?
I understand there are quite a few retirement calculators in the App store. Some are free, others are not free. MyNestEgg belongs to the latter category. My goal here, as I said the the product description, is to provide a simple and easy to use to calculator retirement savings/income. It shows the “saving progress” and “income ratio” which combined give the user an idea about where she/he is in terms of saving, and what income level to expect when she/he retires. Also the input data is saved on your iPhone, so as the user runs this app from time to time, she/he can get an idea about how the retirement savings account does over the time (so that she/he can act accordingly).

2. Does it support language other than English?
The app use English only at this time. However, as I explained in the support page, the user can adjust the “regional format” to get the local currency.

3. I don’t have iPhone, so…
The app can be run on iOS 3.1.2 or later powered devices, which includes iPod Touch and iPad besides iPhone.

I saw some useful web based calculator, such as this one created by FINRA. One limitation is they don’t save the data, so you may want to write down the results (or better yet save to Google Docs) after doing calculation.

Also, I am consider porting (creating) the app for Android, if there are enough interest to justify my effort.
