Maya Long Count Updates

It has been a pretty busy couple of months. The first thing was that I ran into the problem with the glyphs. I got all of the new glyphs redrawn, scanned, cleaned up, and integrated into the application. That took about a month to sort out. I did get everything integrated and here's the screen shot from the main screen. Once that was done, I then submitted to the App Store. It was the first application that I've published into the App Store (link here). Given that it was a total "stealth launch"it's been doing a bit better than I expected. Last night I tweeted:
"This is cool. I've earned $3.50 US, $1.26 Australian, $0.70 Canadian, €1.08, and ¥60 from my app. Taxes should be interesting."
Overall there have been 17 sales in 6 countries. I'm interested to see what happens after the end of this b'ak'tun - whether there will be additional interest or if I'll see my sales drop to zero.
I decided to do a free, ad-supported version as well. Hooking up the iAd banner was surprisingly straight-forward. It took very little time to get the banners installed but when I started looking at doing the full-screen ads I've seen in other apps I found out quickly that the iAd network doesn't do it for iPhone - just iPad.
I've been playing with the idea of using Greystripe at one point and this provided the opportunity to get it integrated. With iAd's lack of full screen ad support on iPhone, Greystripe was the solution. The was a problem, though, in that the test ID that they provided failed to work properly. I "violated" the terms a little a turned on the ads while I was testing. Given that I had done most of the work already around the testing, going with "live" ads wasn't a gigantic hit on the volumes (I think I used 7 impressions for testing).
I did get the free (lite) version submitted to the App Store on December 12th and it sat in review for a few days. I did get a notification yesterday that it was being reviewed and very quickly went from "In Review" to "Ready for Sale". Here is the timing on that:

 I was amazed that it was less than 2 hours from start to finish. Overall it was pretty amazing to see how quickly they got it squared away. Admittedly there was already one there that was practically the same thing but it was a different application. My original app took almost 2 days in review. This was 2 hours.
Anyway, both apps are now officially available for sale and Otto Von Productions, Inc. has published and sold its first applications. Now I just need to get the other 41 ideas I've got swimming in my head completed and published. Maybe I'll end up making this whole thing work after all.

New glyphs are done!

So I spent a little time finishing off the glyphs for the app. I think they look "okay". At least "okay" enough to be in version 1.0. And, for me, they're "freakin' amazing". *sigh* As I said, my graphic artist skills leave MUCH to be desired. Anyway, without further ado, here are the glyphs I made for the app.

The glyphs for my app

Not bad, eh? Yeah, I think they'll suffice. I did spend quite a bit of time making them and hope that they'll be met with approval by the community. It was definitely not something I felt at all comfortable doing, but sometimes it helps to get out of your comfort zone.
I'll point out that these are the original drawings - I haven't cleaned them up at all. I will be extracting the individual glyphs and improving them before incorporating them into the application. From personal experience with other graphics exercises, this will take several hours. I just hope I'll be able to get enough time strung together to make it happen. I also need to get the description written for the application, so that's something else I need to get a block of time to accomplish.
So, there we are. Hope you like the preview here. Once I'm done and submit everything to the App Store, I'll post a link.

SLIGHT delay on Maya Calendar App

So as I was going through the submission process to get my Maya Calendar application onto the App Store (yes, that was actually happening!), I needed to create a description of my application. I decided to go see some of the other applications in the space to see what they had crafted for their descriptions - check for inspiration, really, not plagiarism. No, seriously - no plagiarism. I think I might just like typing that word...

Mine on left, theirs on the right

Anyway, as I was going through looking at "maya calendar" (as opposed to "mayan calendar") I stumbled upon an application - using the exact same graphics. In fact, their icon was the same idea (with a different glyph - see right for comparison). Well, *(^*&!@. And AS I WAS SUBMITTING MY APP! I found that the website I'd "borrowed" the glyphs from was the same site that had the application I found. *facepalm* O.M.G. Bad me for thinking they wouldn't be used somewhere else.
So what did this mean to my calendar app? It meant that I needed to have some new glyphs. I asked my daughter if she'd be inclined to draw them (there were 44 required) and she agreed. Then she drew the first one and decided "um, no thanks - that was HARD". So it fell to me to draw some new ones. I used some different sources to get ideas for what they looked like (including the ones that I can't use now), but I've redrawn all but five of them. Next will be scanning them in, then cleaning them up, then integrating them into the app. The nice thing is that integrating them is a piece of cake - I just need to replace the existing files with the new ones. Also, I'll have higher-quality ones to use for an iPad app (if I do that). While they will be similarities to other glyphs on the web, they're hand-drawn (by yours truly) and lacking the funding to fly to Central America to tromp around Maya ruins looking for samples, I have to do it virtually. Which means other peoples' pictures.
So I'm close to having that app in the store. I'm really hoping that I'll be able to get it done by the end of the weekend. We have a very busy time planned, but here's hoping that I'll have a little time during those two days to get this sorted out and submitted. In the meantime, I'm working on getting a description put together so I can just copy/paste it into the submission page and go from there.
Fingers crossed for a successful submission. Then it's the waiting game for approvals. I'll post more on that as we go through that process.

Nearing completion

Current launch screen for the app

So I've been working a few hours every night trying to get closure on the Maya Calendar application - and I'm almost there. Except for a marathon Bejeweled Diamond Mine session this evening (I didn't want to quit until I'd topped 200k) I've pretty much been working on finishing up the application. I've got the backgrounds all changed - they look very nice now - and am working on the final touches. I was going to do a universal application - both iPhone and iPad - but the size on the app was making it ridiculously large. Like 60 MB large. Wow. Um - no.
What's left you ask? Well, I've got some "about" kinds of things to finalize. Need to get the application version information in there as well as information about HOW to use the app. Plus I wanted to put in some text about the long count calendar - where did it come from, how was it used, etc. Once I get those things in and working as expected I think I'll be ready to build it for distribution. I don't have an iPad version yet at all. I think while I'm waiting for the App Store approval process to complete I'll work on the iPad version. I've got all of the graphics and logic - just need to change up the display. I think.
Things have been coming together over the past few days. I feel that I've been productive - moreso than in weeks past. In order to get things finished I need to do something I haven't ever done before, so I do still have a little more work to do, but I feel now that I'm closer than ever to having something completed that can be submitted to Apple. And that will be a huge boon to my self-esteem these days. I also made some adjustments to the graphics that, for a non-graphic artist, I feel pretty good about.
Anyway - just a quick update. Looks like things are getting close. Now to sprint to the finish line and be done with this.

Oddness with the Maya Calendar

So I've been reading up a LOT on the Maya* calendar over the past few months. There are two different calendrical systems - the Long Count (which is what we hear about when people talk about the end of the world in 2012). The current date in Long Count (as of this post) is 12.19.19.12.0. There's another calendar is called the Sacred Round and uses what are called Tzolk'in and Haab dates. This calendar was more religious in nature and had a full cycle of about 52 years. When doing calculations for Long Count or Maya calendars it's common to include both the Long Count and the Sacred Round dates.
One thing that seems clear is the basic calculations to get the Sacred Round dates. The Wikipedia article describes pretty clearly the arithmetic required to derive these. The regular Sacred Round cycle is 360 days and there are 5 Wayeb days (that were considered unlucky) to make the calendar 365 days long. Close to the 365.2422 days our tropical calendar is, but it means that the Sacred Round shifts one day forward compared to the tropical year every 4 years.
One problem is that I would like for my application to work for dates all the way back to 9999 BCE (and forward to 9999 AD/CE). Most calculations are done using Julian days as a baseline, but the Julian dates start in 4730 BCE, a little later than my 9999 BCE desire. What's a developer to do? Well, one option is to try to address the negative values that come from going before the start of the Julian dating scheme, which is what I initially thought of doing. Then I realized that since there is a higher-order cycle above the currently accepted five values, I could add what's called a piktun worth of days to the count, in essence moving back the Julian calendar about seven thousand years. I did this and it worked great for the Long Count calculations - I just subtracted out a piktun if it was past the beginning of this cycle or not - it all worked out. The Sacred Round, however, was a different story.
The reason is that the Sacred Round starts at specific values for tzolk'in and haab. Moving back a whole piktun, though, means I needed to recalculate the tzolk'in and haab values. I figured out what the new offsets were and after resolving some oddness with displaying the correct glyph for the tzolk'in and haab I seem to have gotten everything working.
The only things I have left to do to get this thing out the door is finish the polish for iPhone and get the iPad version looking reasonable. All of the testing I've done to date is solid. I still have a few things left to validate, but I actually have a high confidence that it will work pretty well. Then two versions - one free and ad-supported and one for $0.99. Then I'll have broken my 3.5 year drought of getting apps into the App Store. Yay?

* You'll note that I'm not using "Mayan" anymore. I learned that Mayanists (scholars who study the Maya history) use "Mayan" for linguistic elements (the language) but use "Maya" as an adjective for "things that are from the Maya culture"). I will bow to their superior expertise and understanding in this particular matter. 

More Mayan Madness and Inspiration

So it's been a while since I've posted. Unfortunately in the weeks since then I've had a hard drive "almost" fail, a Time Machine restore TOTALLY fail, the hard drive FINALLY fail, and lots of restore pain. In short, it's been a hell of a few weeks. But now I'm mostly back to normal (well, the laptop is) and running again.

19 Aug 2012 in Long Count

I've been working on the Long Calendar app for the past few days. So far I've added a lot of better graphics to it so it looks better than it did before (see picture to the right). I think it's starting to look a little better. I wasn't planning on working on the glyphs until I had completed everything else, but I'm actually really close now. I have two remaining bugs. For some reason the Haab and Tzolkin calculations are incorrect. I'm guessing I messed something up when I fixed some +1/-1 problems earlier. And BCE dates aren't working correctly right now. Again - I think I managed to break them at some point during development.
One thing I'm not doing much and need to be doing a lot more is the unit test. Xcode 4.2 integrated a unit testing framework into the system, which is awesome. I need to spend some time really beating it up and understanding it a lot. With this applet I feel that it could be beneficial (it would have caught the changes that broke the calculations), but I'm also pretty far down the path. I've got a set of tests that I do whenever I make changes, so I'm not totally out of sync with current development methodologies, but still feel that with all of the agile experience I have that I'm not being "true" to the methodology by not doing it for my own projects. Especially since Apple has done the "right" thing by encouraging developers to do it. Next project I must do it.
Regardless, things are starting to come together with this. I expect that I'll be able to get this completed this week, I hope, and get it into the AppStore next weekend. Earlier would be better, but there's a lot going on right now - lots of swirl and lots of stress.
On a good note, though, I spoke with a friend from my HP days - Cooper. He works at Microsoft right now and I was in Seattle last week and rang him up. He's one of the most talented engineers I know (perhaps the most talented). He's also one of those people who is completely committed to whatever it is that he's working on at the moment. He inspired me to work on things that made me happy when we worked together. We actually started talking about starting our own company before MS offered him riches that would make Solomon blush. But it's Coop who really encouraged me to dream bigger and work harder to achieve those dreams.
I've sort of lost sight of that in the doldrums that are everyday development. It's easy to forget the why of what you're doing in the day-to-day of doing. What do I want to have? The ability to be with my family when and where we want to be. To be able to provide for them while not being beholden to a time clock at a wage-slave job. To not be a sarariman. As you probably know, I have a 9-5 at Comcast. The "job" is good - challenging to be certain, but I'm well-compensated and enjoy working with my coworkers. But it's not what I want to do in the long-term. Before I got this job I told my wife that I wanted my next job to be my last one - that I would make this Otto Von thing work come hell or high water. And what's happened in the 2.5 years since I started at Comcast? Not a whole lot. I've managed to learn a lot but at same time waste a lot of effort not focusing on the end goal.
Talking with Cooper has really re-focused my energies on that end goal. I was reminded of the possibilities we had back at HP. Of the things we talked about doing and the places we'd go. Of the games we'd write and the lives we would change. Of the paradigms we'd create with our innovation. We'd be the Nintendos of the game world. And that's gotten lost.
So, here we are in August. What will the next few months bring? I don't know, but I do know that I'm reconnecting with those "halcyon days of my youth". I'm remembering WHY I'm doing this and why I need to make this more than just a hobby. It just takes a look at my family and a chat with an old friend to bring everything back into focus with a clarity I could scarcely recall. Almost like a haze that slowly dims your vision. Over the years it just seems fuzzier than it used to be. And then you clean the haze away. Now I just need to keep the haze away.

More Long Count Calendar Updates

I've been making some awesome progress on the long count calendar application. I've got all of the math working (although I still need to test all of the nasty edge cases to make sure it calculates things correctly), but for anything after 1582 (when the Gregorian calendar came about) it seems to be working just fine. To test the date calculations I'm working on the ability to convert ANY date into a long count. This is a nice feature to have (what was Jan 1, 1900, for instance?) and will be useful for people looking to compare against other date calculations. The other thing I'm going to provide is the ability to put in a long count date (13.17.5.2.1) and see what date that converts to in a Gregorian calendar.
Normally, the main issue about converting from these earlier dates to later ones is that not everyone transitioned to the Gregorian calendar at the same time.Most of Catholic Europe adopted it in/around 1582. The British empire didn't adopt it until 1752 and the Soviet Union was in 1918 (right after the Bolsheviks took power and Russia became the Soviet Union). The Wikipedia article on the calendar has a nice chart showing the adoption times for different countries. So depending on where you were you had a different calendar. I'm pretty sure that the date is the 1582 and using the default NSCalendar objects will fix it for that date, I believe.
I will say that Apple seems to have done a good job with the calendar objects. NSCalendar and NSCalendarComponents are very nice little objects that really do simplify the mathematics. I have to convert to Julian dating anyway, which makes the math about as easy as it can be, but having the system provide some of the common functionality is very handy, especially being able to extract out year, month, and day without any extra divs and mods on my part. It will even provide the day of the week if you need it (which I don't in this particular application). I still need to dig into the objects a little more, especially with the pre-1582 dating - just to make sure they work as expected.
I did get the T'zolkin and Haab calculations into the application, so not only does it show the long count form (12.19.19.8.2 for today) but also the "month" and "day" (5 Sotz' 1 Ok - also for today). So everything is present in the application now from an implementation perspective - all the math works, it grabs the right images, etc. I need to get some better quality glyphs for the application, though, because the ones I have are low-res and won't look good on the iPhone let alone an iPad. That could actually be a major pain in the butt - one I'm not concerned about right now (those two stories are last on my kanban board), but I recognize that I'm going to have to spend some time either finding some good quality ones or drawing them myself (shudder!).
Overall things are looking really good. I think I might be able to make some good progress this weekend during downtime for Yeomen of the Guard. I'm off-stage quite a bit and with 3 shows in 4 days, I've got a lot of potential time to move this forward. I'm setting a goal of having the Gregorian to Long Count conversion done around Saturday night, the Long Count to Gregorian conversion around Sunday afternoon, and the reckonings done by Monday night. Which means that all I'll have left to do is get some good graphics next week and then I could, in theory, put it out on the App Store by the end of June - the first such Otto Von product to be available. All in the course of 3 weeks. Wow.
So keep your fingers crossed - I need all the luck I can get on this rapid development path!

Silly Little Mayan Long Count Calendar Utility

So for post 101 (that's 5 in binary), I'm giving a sneak peek into a silly utility I decided to develop. I don't know why, but it's just been one of those things that I thought "you know - why not?". So I am. And what IS said utility? Oh, it's tres bien, mon amie. And tres sillie. (And yes, I know that sillie is not really French). Regardless, here's a screenshot:

And what, pray tell, is that? Why, my friends, that's a Long Count (commonly referred to as "Mayan") calendar converter. It tells you what day it is in the Long Count (which, ya know, 'ends' on Dec 21 of this year - but not really). The Long Count calendar is actually pretty straightforward. It's mostly based on the number of days since the "dawn of man" which is 13.0.0.0.0 - a date that correlates commonly to August 11, 3114 B.C.E. It uses a Julian dating scheme (every day is just 1 more day) and then divs and mods them into buckets (b'ak'tun, k'atun, tun, winal, and k'in). The main Wiki page gives a pretty good explanation of the whole thing.
I pretty much started it this evening when I got home, but I've been reading about the Long Count for a while now. I'm intrigued by different counting methods. I used to have a devil of a time with them (converting from decimal to binary to hexadecimal sucked). And then I heard Tom Lehrer's "New Math" (YouTube link here - and yes, you want to click it) and it completely resonated. I grokked it. My mom had Lehrer's LPs (if you remember those, you're older than you look) and I listened to them endlessly. Since then I've kind of geeked out at new methodologies.
Anyway, I looked in the App Store and saw a couple of things about the Long Count calendar but saw that some people were disappointed in the lack of functionality of some of those other apps. There are multiple "reckonings" for the start point of the Long Count, but those are all just relative to the main reckoning. It seems simplistic to use the different reckonings for reference use and also to allow people to convert any date. Probably be able to put in a Long Count and have it convert to a Gregorian date as well. So I'll see what I can do to make that happen and quickly.
Given that I have the basic calendar already working in just a few hours I'm actually feeling a lot more accomplished than I have in ages. And that's a good thing. And tres bien, mon amie.
