Apple Machine Learning Journal


Apple Machine Learning Journal

Machine Learning / AI is everywhere. From image recognition, playing Go game to self-driving cars, the technology is getting more and more pervasive in our everyday life.

Google, Facebook and Baidu are known as the leaders in machine learning field, and scientists from these companies openly contribute their studies, papers and findings. In contrast, majority of AI research by Apple scientists and engineers are not known to the rest of the world.

Apple has launched a new blog called Apple Machine Learning Journal that publishes “posts written by Apple engineers about their work using machine learning technologies to help build innovative products for millions of people around the world.”

Could this be the first step to a more open Apple regarding their AI research? Check out the Apple Machine Learning Journal blog.

How to clear iPhone’s memory without a restart

Apple’s company line has been that with iOS’s excellent memory management, there is no reason for users to quit apps or restart to clear off memory that causes slow down. In reality we all know iPhone tends to slow down after a while. Restarting your device is not the only way to make it run smoothly again. Here’s a simpler trick:

Find free and public Wi-Fi hotspot using Facebook

Find free and public Wi-Fi hotspot using Facebook

Facebook is launching a new “Find Wi-Fi” feature in its iOS and Android app. This is good news for those Facebook users who travel a lot and requires free Wi-Fi.

“Find Wi-Fi” is located under “Apps” section in Facebook mobile app. You will be prompted to enable this feature when you first access it. One caveat is this feature requires “Always” location access. “This allows Facebook to build a history of precise locations received through your device. You can see or delete this information in your Activity Log”.

Facebook Find Wi-Fi depends on businesses to add to their Facebook Page if they have free Wi-Fi hotspot available. Thus it does not cover all available public free Wi-Fi.

App Development with Swift

App Development with Swift

Since its debut in WWDC in 2014, Swift programming language has become one of the most sought-after skill for developers on the Apple platforms. As part of Everyone Can Code effort, Apple has released a new app development full-year curriculum called “App Development with Swift”. The course, comes as a free download ebook on the iBooks Store, is designed for those who want to pursue careers in iOS app development.

5 things Apple did not mention in WWDC 2017 keynote

5 things Apple did not mention in WWDC 2017 keynote

It was a jam packed WWDC 2017 keynote by Tim Cook and his team. Besides new version of iOS 11, macOS 10.13 High Sierra, watchOS 4 and tvOS 11, Apple also launches new update to iMac, MacBook and MacBook Pro, new iMac Pro, new 10.5” iPad Pro and new Siri-powered $349 smart speaker HomePod.

This WWDC also signals Apple’s inroad to being an AR (Augmented Reality) platform, there is an emphasis to GPU processing in its Metal 2 API. And high end iMac are now boosting GPU good enough for AR/VR play and production. In addition, Apple is making it easier for developers to add Machine Learning (ML) into their apps wth its Core ML SDK and Visions API.

Here are 5 things that Apple did not mention in its keynote:

1. iOS 11 does not run 32-bit apps

Apple has been displaying warning message in iOS 10 when you run a 32-bit app. Apple actually advised its developers to upgrade to 64-bit since mid 2015. In iOS 11, 32-bit games and apps will not run. Check out this post on how you can identify if your favourites apps are 32-bit.

2. New Magic Keyboard with Numeric Keypad

Magic Keyboard with Numeric Keypad

Kind of surprising to get a full-size wireless keyboard from Apple. Its $129.

3. New iCloud storage pricing

Apple has updated its iCloud storage pricing by increasing what you pay $9.99 per month for from 1 TB to 2 TB. The rest of pricing tiers remains unchanged.

– 5GB free
– 50GB $0.99
– 200GB $2.99
– 2TB $9.99 

4. MacBook Air is updated with faster processor

MacBook Air is not dead. The processor gets a speed bump from 1.6GHz to 1.8GHz.

5. MacBook Pro is still limited to maximum 16GB memory

One of the major complaints with the redesigned 2016 year end MacBook Pro is its 16GB configuration limit. This limit supposedly pissed a number of “pro” users to switch to use Windows notebook. The latest update to MacBook Pro is sticking to the 16GB limits.

Identify list of outdated 32-bit apps in iOS

Starting with iOS 10, Apple has started displaying warning message when you’re running a 32-bit app. You might encounter messages such as “The developer of this app needs to update it to improve its compatibility” or “This app will not work with future versions of iOS”.

Apple plans to phase out 32-bit apps in the App Store and has been advising developers to migrate to 64-bit. Rumour has it that the next version of iOS 11 releasing this fall will support only 64-bit apps. Apple actually requires its developers to support 64-bit when they submit new app or app update since June 2015.

Unfortunately there are still hundreds of thousand of apps in the App Store that are 32-bit only. Which means these legacy apps has not been updated by its developers since mid 2015. With iOS 10.3 update, Apple makes it easy for you to identify these apps. Go to Settings > General > About and scroll down to the Applications. If you can tap on this line, you will be taken to the “App Compatibility” page, which list all the apps that are not compatible with future iOS version. You might want to reach out to app developer for 64-bit support if you’re using any legacy app.
