Local Siri

Thursday, May 17th, 2018

Here’s my WWDC prediction for 2018: Siri will be significantly replaced with a new, on-device Siri. A few attributes of this new Siri that would make it interesting, and give it a shot of coexisting in a world with Google Assistant, Alexa and Cortana: Requests will run directly on your device. No more waiting for […]

Formatting CVaListPointer

Monday, April 9th, 2018

So you’re using libtiff in Swift, and need to implement the TIFFErrorHandler. Or, for whatever reason, you have a CVaListPointer (the args parameter, below) and a format string, and you want to format. Here’s how: let errorHandler:TIFFErrorHandler = { (moduleNamePtr, formatPtr, args) in guard let formatPtr = formatPtr else { // No format string – […]

The Amazon Web Services Platform

Thursday, October 19th, 2017

I’ve been working with Amazon Web Services as part of a new job, and I was surprised to see how many rich services Amazon is offering under the AWS banner now.     I made a point of looking at every one of them (as of October 2017) and reading enough about it to get […]

Parsing Hex Strings in Swift

Saturday, August 12th, 2017

I want to turn the string “0x02 0x03 0x04” into an array of bytes ([UInt8]). Seems simple enough right? let hex = “0x02 0x03 0x04″ let components = hex.components(separatedBy: ” “) let array = components.map { UInt8($0) } But the UInt8 constructor that takes a string doesn’t understand the “0x” prefix to indicate hex strings. […]

OperationQueue and dynamic priorities

Sunday, May 7th, 2017

I had a question about OperationQueue that I couldn’t find an easy answer to: Can you modify the priority of an operation once it’s been added to the queue? My situation is that I have some background operations that are executing, but the user may choose to view one of these items interactively, and at […]

If you find that when some device on your network is uploading data, the entire network becomes unusable due to excess latency, this post is for you. There's a term for this, BufferBloat, and it refers to the a phenomenon where your ping times increase due to excessive buffering at a choke point on your […]

Occasionally Connected

Thursday, February 16th, 2017

I think it's easy for people who have a reliable always-on internet connection to forget that much of the world does not. Even those of us who do may prefer not to use cellular data as much as possible. What I'd like is for the phone to sync as much data as it can while […]

Emotions by Hodelpa

Monday, February 6th, 2017

We went to the Dominican Republic for a week, and stayed at Emotions by Hodelpa. ([TripAdvisor]). Here’s some information about the hotel that you might find useful if you’re considering this resort for your trip. The place is always referred to as “Emotions by Hodelpa”. Hodelpa is a chain, and they recently bought this resort […]

Controllers vs Mouse and Keyboard

Sunday, November 20th, 2016

This was (and is, until tomorrow, November 21st, 2016) a free weekend in Overwatch, so you can download and play the game for free on PC, PS4 and Xbox One. I play a lot of Overwatch on the PS4, so I thought I’d take the opportunity to try it on the PC. I’m not very […]

More RAM Please

Tuesday, November 1st, 2016

Here’s my two cents on the new MacBook Pro’s, not that anyone is asking. This tweet sums it up: “I’m struck by the cultural divide between dismissive Apple defenders and people who buy an expensive mac for real work every four-five years” – @pinboard The main reason I’m uncomfortable dropping that much money on a […]
