Like Spotify’s complaint before it, yesterday’s “App Store Principles and Practices” document from Apple got me thinking.

Apple talks a lot about free apps not paying anything (which isn’t entirely true of course), and it’s always pitched as a feature.

But the more I think about it, the more I think it might be a bug.

This effectively means that all paid apps have to subsidise all free apps. Is this what’s preventing Apple from reducing the 30% fee?

The problem with “agile development” is that it is both a methodology and a buzzword. What this means in practice is that people who do not understand it implement parts of it without appreciating the whole. This usually results in more overhead but without the benefits.

I’ve come across this multiple times in my career. The usual refrain is “we’re agile so we don’t need documentation.” The “agile” aspect is more often than not, merely the assertion that the project is agile. Or someone says that the code is the documentation.

As I’ve done for the past few years, here are a few thoughts on the new version of iOS that will be heading to your phone in a few days. Usual caveats: my usage patterns are probably different to yours, I have a 6s and iPad mini, not whatever weird and wonderful hardware you have. I’ve been using the beta on my iPad since early August and on my iPhone since late August.

Here is goes again. Apple announces new MacBook Pros (or there are rumours about a new Mac mini pro) and the hoards pile on it saying it’s not a “Pro” machine. But what does that actually mean?

Traditionally the label “pro” is short for professional and is used to describe people who make their living using the tool. Sadly that definition is so ridiculously broad that it’s not terribly useful. What does a video editor, a writer, a 3D modeller and a software developer have in common?

As I’ve done for the last few years, here are a few quick thoughts about today’s new iOS release, version 11.

I’ve been using the iPad version since the beginning of August and the iPhone version for only a couple of week but I think I have reasonable picture of what you’re going to see.

## Good

• Multi-app support on the iPad. Wow! It’s quite different. You might need to give it a while before you get used to it. I also found that I needed to rearrange my dock so that apps I use to multitask are quickly available
• “Swipe up on the iPad keyboard to get symbol characters.” Such a time saver
• The voice synthesis of Siri is way better. But I agree with Gruber, if I could have dedicated engineering resources to Siri that wouldn’t have been where I would put them
• iCloud sync for Photos. No more training each device to receognise each person!
• Lots of nice, minor changes. The “Now playing” lock screen widget, the “play” button at the top of playlists/albums in the music app
• Control Center is improved (but see first item in the “ugly” section below)

## Bad

• I’m guessing this has something to do with the iPhone X, but the one 3D Touch gesture I used all the time was the hard-press on the left side of the screen to trigger the app switcher. That’s gone in iOS 11. This is going to take a lot of getting used to
• It won’t work on older devices. I get the “why” but it always sucks when they get left behind

## Ugly

• Why did the WiFi button is Control Center change to be “disconnect” rather than “switch off”?!
• Not sure about some of the animations, especially on iPhone.

How do you interview people for developer and technical jobs? This is an enduring question, and one with many angry factions.

It’s too big a subject to tackle in its entirety and I have no intention of trying. Instead, I want to talk about one aspect: should you ask Computer Science questions or not?

In one corner are the people who argue that you never need to implement a linked list or write Quick Sort in real life, so asking you to do that in an interview is unreasonable and excludes good candidates. They argue that there are more important things to consider, such as the use of applications frameworks or design or working with other people.

This was all set to be a story of how much the whole family were enjoying the Nintendo Switch¹. While that’s true, there’s another side. We’ll get to that but let’s start with the good stuff.

Long story short: after just over a week, we’re all getting a lot out of it. The games are fun, even my three year old gets a kick driving Princess Peach around what looks like Sugar Rush from Wreck-It Ralph.

I thought I’d jot a few notes about next weeks WWDC, Apple’s major developer conference. Full disclosure: I’ve not been following the rumour sites very closely this year. I’ve not even done as much iOS development since WWDC 2016 as I have for the last few, so what follows is just a wish list. It’s based on neither leaks nor an in depth knowledge of failings of the current developer tools.

Virtual assistants are all the rage now, in the press if not in not people’s lives.

I am not claiming to do a thorough, like for like comparison. What follows is my subjective, personal experience. Your usage patterns, successes and failures may be different to mine, but I think my conclusions should broadly hold. We’ll see.

I’m comparing an Amazon Echo, an iPhone 6S and the Google app on that same iPhone. I know I’m not using Google Now in its native environment. That was unavoidable and may hobble it. You should bare that in mind if you use Android.

When I got my new MacBook it wasn’t complete. I sat it down on my desk and nothing would connect.

I tried to plug in my monitor, but I needed a dongle to connect to my DVI monitor. My FireWire external hard-drive needed an adapter. I had to get a card reader as my camera takes CompactFlash cards. Even my USB hub needed replacing because my new computer came with a newer, faster USB standard.
