DreamRight Wherefore Art Thou

I introduced DreamRight in my aptly named post Introducing DreamRight. Since then I’ve graduated from RPI, moved to Schenectady, adopted a dog and started work as a mobile developer at Transfinder. Excuses, I know.

Anyway, you’ll be absolutely devastated to hear the development on DreamRight has been temporarily suspended. My reasons are threefold (and will sound an awful lot like excuses).

  1. I had garnered all the knowledge I could regarding custom drawing routines and UIView Animations
  2. I moved onto another app that you’ll soon be hearing about
  3. I was busy!

That’s not to say I didn’t make any progress… I managed to get my custom dream log display working jusstttt right – check it out:

Introducing DreamRight

I’ve been interested in lucid dreaming and sleep science for quite a while… One of the best ways to improve lucid dreaming skills is to keep a dream diary. I’ve tried this in the past and simply cannot bring myself to wake up and immediately type out or write down my dream as it quickly starts to fade from memory. I’ve had more success using the voice recording app but I had no easy way to organize these snippets or do anything useful without exporting them. Additionally, it quickly became too much trouble for me even start/stop/save a clip when all I want to do is close my eyes again.

DreamRight is an idea I’ve been tossing around in my head for some time. I’m focusing my personal programming projects on UI/UX where my skills are most lacking and decided this project would be a great candidate. Here’s a standard use case for the app:

  • Enter sleeping mode
  • Have a dream
  • Tap anywhere on the phone to activate voice recording
  • Tap again to stop or wait for the configurable silence timeout
  • Rinse and repeat until morning
  • Tap and hold to leave sleep mode and save your dreams
  • Add notes, transcribe recording to text, share dreams, etc

In essence this is a pretty simple app. However, like most of my projects, I can think of countless ways to expand functionality. In my other large scale iOS project, Rise, I started with the utility and am leaving most of the design until later. With DreamRight I’ve decided to take the opposite approach – placing design first and only moving on to a feature when I’m absolutely satisfied with the design.

So far all I’ve done is create the intro screen along with a little helper I built to design the star animations. I’m working on the dream log view and then will move on to the actual sleep mode. If anyone with an iPhone is interested in testing I’d be happy to add you as a tester – all I need is an email address. Take a look!


Quiz App for Transfinder

I’m graduating soon and have been busy the past few weeks applying and interviewing for a handful of positions. One of these positions is with a fairly small company, Transfinder. Transfinder provides tools for school districts and parents to enhance safety and track a variety of factors for report generation. After a successful phone interview I was given a programming project for the next stage of the interview process. Transfinder gave me access to their API for three days and I was tasked with developing a program utilizing the API in some way.

The assignment was very open ended – there were no requirements on a programming language or specific functions. In the past year or so my personal projects have shifted mainly to iOS and Objective-C so an iPhone app was the clear choice. I developed an app that pulls data on students and schools from Transfinder’s API. The user is then presented with a simple quiz on students’ association with schools. This is a fairly simple description but the project also involved multithreading and custom draw routines. I’m very happy with the end result and it landed me a second, in-person interview. Check it out!

Campus Key for Foothill College

I took an iOS development class at Foothill College a little over a year ago and ended up developing a small app for them. It’s a system to generate “key request forms” – a form that faculty and staff have to fill out for each and every office/building they need access to. I learned some neat tricks making it and am pretty happy with how it turned out.


Batch Download iOS App Icons

This site has been in serious need of a redesign for years and a graphic designer friend of mine had the idea of spelling my domain using app icons! I loved this idea but I had a slight lack of letter based app icons to play around with (read: none).

It turns out Apple provides an iTunes Search API which I could use to programmatically access search results for any terms/categories/etc. The major limitation of this API is that it will only return 200 results for a single search term and has no way to specify pagination (so I can’t, for example, get results 200-400 in my request). The only way around this would be to download and parse the entire Enterprise Partner Feed which contains all metadata in the iTunes store. Regrettably, I am not an enterprise partner (yet) so I don’t have access to that data.

The JSON search results specify locations for both 60×60 and 512×512 app icon images. The script I’ve written prompts the user for a comma separated string containing a list of search results. The script will then query the Search API for each of the terms and download the 200 results into a subfolder named by the associated search term. There’s no support for searching in specific categories only or searching the top charts but that functionality would be trivial to add using the API documentation as reference.

Here is a link to all of the “letter icons” I’ve accumulated: letterIcons.zip (sorry, I only cared about SIDEAP)

I’ve also included the first draft of the new site logo (currently using the 2nd draft as of 8/29/14). If anyone wants to try their hand at another design I’ll give them two million dollars. Don’t forget to grab the source below as well! My apologies for the lack of comments in the code… I’m better than that.

Introducing Rise

I’m an avid biker currently living on the slope of what could be considered a plateau. Downtown elevation is ~5-10 meters, I live at ~60 meters and the top of my campus is ~100-120 meters. Suffice to say, I’ve been doing some hill training. I’ve used MapMyRide to track my workouts in the past but I’d like a workout tracker centered around elevation. Now entering the ring: Rise.

Rise aspires to be a simple, straightforward application geared entirely around elevation data (leaving the possibility for almost endless expansion). So far, response has been mixed – many people don’t see a need for this app and it’s been brought to my attention that Strava provides similar elevation graphing options. However, I believe by focusing mainly on elevation that my app will be able to match my high standards of simplistic UX and beautiful UI. Also I want it so I’m doing it.

I’ve been developing Rise in my free time for a little over a month and I’m very pleased at the progress I’ve made. I’m still in the experimental stages and have put no thought or time into UI or UX. I’m confident I’ll be able to get the elevation graph to display just the way I want it but I need some guidance/assistance in coming up with a “workflow” for the app. I haven’t reached the point where I’m ready to dedicate my own focus toward UX design and it would be wonderful to find someone interested in working on this with me.

Here are the features I’ve got working:

  • Local GPS lat/long/elevation logging
  • Google elevation API queries using lat/long from the GPS
  • Data upload functionality for data to aid with a best-fit algorithm for the elevation chart
  • Local viewing of uploaded data in CSV or TXT with the ability to export the data
  • Graph support – about halfway to where I’d like it to be but fully functional in its current state
    • Zoom and pan within proper bounds
    • Logic implemented for gradients under slopes of varying strength
    • Dynamic axes that update automatically upon pan or zoom

Here’s what I’ve got on the docket before an initial release:

  • Theming support
  • Ability to select slopes of the plot in order to view additional data like min/max/average speed
  • More chart data animations
  • Chart export options
  • Data unification algorithm
  • UI + UX

Well, that about does it for this introductory post… here are a few links for you guys and a look at the current graph:

CatSpam: An Innovative Approach to Spam

I often come up with programming ideas as I’m trying to fall asleep and, more often than not, this forces me out of bed to start some silly work. About a year ago I had an idea: Would it be possible to create a script to text friends, family and/or strangers with some form of spam. For some reason I landed on the innocuous topic of feline facts and got right to work.

My first idea was to use the email system that has been in place for some time now to send the text messages. However, this requires me to know what network the phone is on and that’s a problem I wasn’t interested in dealing with. Then I remembered Google Voice… For the uninitiated, anyone with a Google account can now get an additional phone number, free of charge. You can configure Google Voice to forward your calls to whichever phones you chose while keeping your primary phone number concealed.

Python, being one of my favorite languages was the clear choice for this task. It turns out that Google has no public API for their Google Voice service. Thankfully, some pro programmers have created Google Voice libraries for a handful of languages, including Python. I used pygooglevoice which ended up being a pleasure to work with. The program prompts the user for their Google login (which is securely handed off to Google for verification) and then asks the user for the phone number they would like to send spam to. Also configurable is a time interval in which the texts will be sent. The cat facts are read from a file located in the same directory and, in theory, could be replaced with any text file in the same format.

Enough about the program – here it is:

If you’re interested in the actual catfacts.txt file you can check it out here: catfacts.txt

Here are packaged executables for Windows and OSX – make sure you have a catfacts.txt file in the same directory as the executable or the app will crash!

Add Markers to Google Map from CSV

I was recently asked to create an HTML page that would access a CSV file containing a list of latitude/longitude values and generate a map with markers for each location. This project was a proof-of-concept challenge for me so I’ve really just made a barebones implementation. That said, it should be very easy to expand using only Google’s API documentation for reference. Google Maps were the clear choice as they’ve become a bit of a de facto standard. Enough – let’s dig into the code!

This block of Javascript converts a local CSV file to a multidimensional array that can be easily accessed and manipulated within memory:

This initialization function is all it takes to generate a Google Map and add all of our markers:

Using these two functions, all it takes to generate the actual map is a single line of code:

You can see this code in action right here: http://sideapps.com/smart911/

If you’re interested in the CSV file it can be downloaded here: http://sideapps.com/smart911/zip-lat-long.csv

I must admit, I am a bit prejudiced toward web applications… However, I found Google’s API and the small amount of Javascript I had to learn very pleasant. I anticipated a much longer process and was very happy to be able to complete the task so logically and directly. Hopefully this helps someone out!


FlowReader: A Revolutionary Way of Speed-Reading

Boston-based tech company, Spritz, has recently introduced a new speed-reading method. This technology utilizes a previously existing presentation method, known as RSVP (Rapid Serial Visual Presentation). A single letter is highlighted to focus attention to a natural center of the word. The brain processes the rest of the word through your peripheral vision. By keeping the highlighted word in the same place, Spritz is able to eliminate minute eye movements that make up a large part of our natural reading process.

My friend Julia Hlavacik and I were discussing this new technology when we realized we might be onto something interesting. Not only does this kind of program have potential for everyday uses such as e-readers, mobile web pages, and all forms of articles; it also circumvents a lot of the problems faced by dyslexic readers.

Dyslexic readers generally have trouble scanning lines of text, finding the next line of text, staying focused on a word in a line, reading on certain colors of paper/background along with some impairment of spatial awareness. This isn’t an exhaustive list, but all of these issues are either alleviated or circumvented through RSVP. Although normal readers may not experience these problems to the same acute degree as most dyslexic readers, this speed-reading program can still significantly boost the average person’s reading. This is particularly useful on small, digital screens where text can be difficult to adjust.

The video below demonstrates a brief proof-of-concept. The text you see is being presented at 250 WPM; the reading speed of an average adult. To many of you, this text will likely appear somewhat sluggish – most readers can easily adapt to 500 WPM or more. I chose to use an open source API called OpenSpritz as the Spritz API has limited customization options and forces users to create an account and sign in. Two examples of customization that would be impossible with Spritz’s API are the color theme and the ability to adjust the WPM on the fly to account for longer words or punctuation.

How to Attach an Image to an Email Using PHP

I recently wrote a small data acquisition system using PHP. I’m not a fan of web-based development and know very little but I had some financial incentive for this project and took it upon myself to learn along the way. By far the biggest headache I ran into was dealing with PHP’s mail() function. There’s obviously a reason so many third party libraries exist that tackle this issue but, being stubborn, I wanted to do it from scratch.

My goal was to generate and send an email consisting of an HTML body with an image attached. Embedding the image within the HTML turned out to be fairly trivial (in comparison) but an attachment was preferred. After MUCH ado I came up with the following function which does just that.

NOTE: This function doesn’t go to any extremes to validate itself and doesn’t make it past very many junk filters. This was fine for my use case as the email will be going to a single administrator who can easily whitelist the domain. However, if this is a concern I would highly recommend using one of the third party libraries as considerable configuration is required both in the PHP and on the delivering server itself.
