Apple rejected my dictation app for using the accessibility API
Apple rejected WhisperPad under Guideline 2.4.5 for using the accessibility API to paste transcribed text. After an appeal that ended in another rejection, I split it into two versions — a compliant one on the App Store, and the original auto-paste version, direct.

Why Janet? (2023)
I never thought it could happen to me. I mean, parentheses? In this day and age? But for the past couple years, my go-to programming language for fun side projects has been a little Lisp dialect called Janet. (print "hey janet") I like Janet so much that I wrote an entire book about it, and put it on The Internet for…

Should you normalize RGB values by 255 or 256?
Let’s say you’re writing an image processing program. The program takes in an image, converts it to floating point, does some processing and finally saves the modified pixels to disk as 8-bit colors. The question today concerns how exactly the integer-to-float conversion should be done. There are two approaches which…

Patching my guitar amp's firmware
I’m having a lot of fun with reverse engineering lately, so when I was looking over the service manual for my guitar amp, a Yamaha THR10c, and saw references to a UART header in the schematic, I got excited. I wondered if anything cool was hiding in there. Next to it was a JTAG header. I knew next to nothing about…

Let's compile Quake like it's 1997
The first batches of Quake executables, quake.exe and vquake.exe were programmed on HP 712-60 running NeXT and cross-compiled with DJGPP running on a DEC Alpha server 2100A. In June of 1996, having shipped their title but concerned with NeXT stagnation, id Software switched their development stack.

Tracing HTTP Requests with Go's net/HTTP/httptrace
net/http/httptrace has been in the standard library since Go 1.7 and most Go developers I talk to have never used it. It exposes hooks for the points in an outgoing HTTP request that you usually cannot see from outside the transport: DNS resolution, connection acquisition, TLS handshake, the moment bytes go on the…

Only 17% of all 64-bit Integers are products of two 32-bit integers
In software programming, the product between two integers is often computed to a fixed number of bits with overflow. Consider 8-bit integers. If you multiply 127 by 127, you get back the number 1 as an 8-bit unsigned integer, with an overflow. The actual full product is 16129. To represent 16129, you typically use 16…

Rust (and Slint) on a Jailbroken Kindle
I recently jailbroke my 7th generation Kindle Paperwhite. While my motivation probably should have been "breaking free from Amazon's clammy and tightening grip", the truth is I wanted a way to use it as a clock on my nightstand. I found this project and figured I could just make some adjustments to the code. And that…
