HexaGBA is a game similar to Super Hexagon, written to run on the Game Boy Advance. While modern computers and cell phones have special polygon-drawing hardware, the GBA does not, so I needed to do a lot of tricks to get it to look good and run at 60 FPS.
My team’s project for the LiveH2H Collaboration Hackathon was a LiveH2H-to-Slack
bridge. It allows users to participate in LiveH2H video calls using a text-only
interface by writing a live transcript of the call into the Slack channel and
speaking chat messages with text-to-speech.
My main contribution to the project was grabbing the transcript by starting a
headless Chrome instance, using the LiveH2H API to get a link to the call, and
using the Chrome Remote Debugging API to connect to the call and intercept
LiveH2H’s Web Socket messages. I worked with Sang Han, who handled the
text-to-speech feature and helped with the Slack integration.
The project ended up winning the first prize. You can see a video of our pitch
in 360 degrees on YouTube,
but the first part of it is unfortunately cut off.
This iOS game was created for my little sister’s birthday party. In it, you walk around a real-world location using your phone to look for items. (It’s not officially licensed or endorsed by the real Star Trek or anything.)
Since Location Services isn’t always accurate enough to do small-scale location, we fake it by using the device’s accelerometer to detect when the user is walking/running. Combined with a hard-coded timer, this ensures everyone takes roughly the same amount of time to collect each item and finish the game.
Why did iOS 9 remove the ability to change checkmark colors with CSS?
In iOS 9, U+2714 HEAVY CHECK MARK is included in Apple’s set of emoji characters. Just like the other emojis, it’s drawn as a full-color bitmap instead of a single-color vector glyph, so you can’t change its color with CSS. (In fact, there’s no guarantee that the check mark will even be black. Other platforms draw it in a variety of different colors!)
To get iOS to draw the check mark as regular text that you can recolor, you need to use a U+FE0E VARIATION SELECTOR-15 character. If you put that variation selector character right after a ✔, iOS will use the regular text version (✔︎) instead of the emoji version (✔). OS X doesn’t have an emoji variant, so these look the same, but on iOS the variants look slightly different:
In HTML, you can add the character by putting a ︎ directly following your check marks.
