Speed Up Your Mac

Apparently, I’ve been using the MacBook with crippled fan for over a year. I have noticed a kernel_task using up all processing time. I found out that it was the operating system throttling performance to stop overheating. It does this by running a non-processor intensive task. This task has higher priority than user tasks including the processor-intensive tasks that are heating up the processor. The effect is that the processor temperature is lowered. But also poor system responsiveness and overall performance.

When I found out about this, I concluded that the fan was faulty and opening  up the Mac confirmed it. I ordered a replacement fan and today it finallly arrived. I immediately installed it and the Mac promptly sped up. It felt like the same huge speed improvement when I upgraded to 8GB RAM and SSD. A fan is officially the third best upgrade for speeding up your Mac.

iOS 9 and Ionic Side Menus

I encountered an issue with Ionic side menus where a previous view would partially obscure the current view. I updated everything, checked all my JS and HTML templates, verified links and state transitions, all to no avail.

I was stuck for quite a while until I finally decided that it’s probably an iOS-specific issue. A search then led me to this Ionic blog entry from 2 months(!) ago: http://blog.ionic.io/ios-9-potential-breaking-change/. I downloaded and applied the patch and that was it.

The issue is caused by an iOS 9 bug that affects AngularJS and thus Ionic. It’s supposedly “isolated to intermittent UI/navigation issues on some apps”. And, of course, I was one of the lucky ones. I can’t believe it hasn’t been fixed yet!
