How to Get Core ML Produce Images as Output

Core ML’s tools to convert other framework’s machine learning models is a pretty awesome feat in itself. However it is by no means complete. I found some issues in converting models which outputs images. Issues which took me a few weeks to solve even after many consultations to Google and Apple’s own forums. But here’s the solution and I’m sharing it with you so that you don’t have to experience the same predicament which I had.

State Restoration Hiccups with Swift

Have you been asked to do a sample project as part of a hiring process? I’ve done it, not only once but **twice** as part of the same process. Here are those projects. You should be able to learn a thing or two from it Either learn the iOS programming techniques behind these two 40-hour projects or learn how to hunt for purple squirrels.

Is Your Server Ready for iOS 9 and El Capitan?

Apple is enforcing a stronger encryption that applications need to use when connecting to their backends. Is your server secure enough to meet Apple’s standards? Being HTTPS doesn’t necessarily imply that it’s good enough.

Apple’s latest operating system updates – iOS 9 and OS X El Capitan – are enforcing stronger network encryption. This is wonderful for users – however it could mean extra work for developers and system administrators.

In short, applications are strongly encouraged to use HTTPS, TLS 1.2 and perfect forward secrecy. You might be saying to yourself, “We’re already serving through HTTPS, so we’re good.” As it turns out, it may not be that simple. It isn’t for Microsoft and you could be affected as well. Yes, at least one of Microsoft’s web services isn’t yet up to Apple’s security standards as of this writing.
