Background As part of an ongoing effort to keep Cartographica up to date with recent changes in libraries that we compile from source, notably GDAL and Proj, I'm in the midst of a refresh of those subtrees in the frameworks that I build from them. Over the past few years …

My previous post about proj floating point investigation discussed an issue that I'd tracked down to the OS level. However, it's clear that this relates to an underlying change to code compiled by Xcode (and/or the LLVM toolchain that it is built upon). Based on a post about Xcode …

As part of digging through my various problems with Xcode 14.3 (Feedback FB12154691, FB12154887, and some test case issues involving floating point math), I needed to install Xcode 14.2 to move my buildfarm backwards. Although this didn't enitrely fix the problem, it was an essential element of the …

TL;DR MacOS 13.3 or 13.3.1 incorporated a change that is affecting calculations in proj for applications running on those versions of the OS. The change appears to be relatviely subtle, only affecting a single test in a single projection and only on x86_64, not arm, but …

I last bought a MacBook Pro from Apple in November of 2019, in the midst of a bout of travel that was about to come to an end. In point of fact, I haven't used my trusty MacBook Pro much in the last 19 months, since the COVID-19 pandemic started …

Today I read of the passing of Larry Tesler, a computer scientist with a long and storied career, spanning Xerox PARC, Apple, Amazon, Yahoo, and others. He's considered the father of the modeless interaction model (think Cut/Copy/Paste on the Mac). I met Larry in the late 1980s, when …

According to an article on PCWorld, Activision-Blizard has pulled all of their titles from nVidia's GeForce Now. In my days as CTO of Haste (a service that improves network connections for gamers), I had occasion to spend a fair amount of time playing Overwatch as part of our test regime …

There's been a lot of discussion about the 2019 Mac Pro and various assertions that it's over-designed, overpriced, or underpowered. Since I decided to replace my venerable 2013 Mac Pro1 with a 2019 Mac Pro, I figured I'd write up my experience with the device as a developer. The …

One of the very first posts on this blog (16 years ago in the beginning of 2003) was entitled All of your favorite sites at a glance which discussed a new pair of apps (NetNewsWire and NetNewsWire Lite) that I'd just started using. Considering the fallout for RSS from the …

Over the past couple of weeks, I once again reacquainted myself with the joy of using TimeMachine as a backup system. (Please, use more than one, at least one off-site and one on-site would be a good idea, consider CrashPlan for the offsite version, we've used it for years and …

When digging around for information about Apple's new Caching Server, I happened across this informative article about Caching Server for Mavericks by Dan Barrett. Definitely worth a read if you're interested in finding out how to make the most of your network connection with your Macs. However, from there, I …

I received a question this afternoon from my cousin about the amount of free flash in her MacBook Air and figured that the answer would probably be useful to others as well. Note that none of this is officially from Apple, so it might be wrong, but I have had …

So with all the wringing of hands and gnashing of teeth over Adobe Flash in the last few days, I just wanted to make sure I got this little tidbit in. When it comes to user experience, Adobe just doesn't understand. Their "platform" of flash brings a mediocrity born of …

Wow! Apple certainly wants more people to sign up as Mac developers, that's for sure. In changes made today, the ADC Premier and Select tiers have disappeared and they have been replaced with Mac Developer through the current developer portal (which has the iPhone developer sign-up as well). Mac and …

Ah, a new release.... must be time for another slew of articles aimed at getting press and money for the "security" folks out there. For those of us with Macintoshes, here is my take on the whole Macintosh virus situation. Every time a new OS release comes out, a whole …

Many of you have already seen that Snow Leopard (OS X 10.6) will be releasing on Friday. I've been running it as my primary OS on my laptop since the WWDC in June and look forward to getting a real install on there. You're probably also aware that PPC …

This is one of those "should have figured that out myself" problems, but I figure I will warn anyone who might be in my shoes.... Check the specifications carefully before investing in an APC UPS. Not that I'm going to suggest going with another manufacturer, just that I'm going to …

Due to a problem encountered by a friend recently when trying to deal with a lost admin password on a relative's Macintosh, I had occasion to revisit the topic of resetting Macintosh passwords. This is both an interesting tip, and a cautionary tale for those with important data on their …

With Apple having announced some new machines with really nice price points within the last week, I've been asked by some friends what my suggestions would be for copying the data to a new machine and removing data from the old one. Here, I'll try to put forth my current …

As I write this today, I'm the happy owner of a new MacBook Pro (the "unibody" or "late 2008" version). So, what of it? So far, so great. I'm very happy with the purchase and I'm looking forward to making a happy new Mac user of the designated recipient of …
