Issues with Airport Express, Airport Extreme, and OS X Yosemite

I finally fixed a problem today that has been plaguing me for the past couple of weeks. For some reason, my MacBook Pro was getting a pitiful internet speed (around 1Mbps on an 80Mbps connection). Sometimes restarting my Airport Extreme router would fix the problem but it would slow down to a crawl a few minutes later. If I moved downstairs (near the router), then suddenly the speed would be much more acceptable.

After spending some time looking at my wireless network settings, I realised I was connecting to an 802.11n network. This is odd as I have a new 802.11ac Airport Extreme. It turns out the culprit was an Airport Express I put in my bedroom which I use purely for Airplay to a set of speakers. It is one of the newer models that supports 802.11n and it was joined to, but not extending, my wireless network from the Airport Extreme. For some reason, and I’m fairly sure it is a change in Yosemite, my MacBook was connecting to that Airport Express via the 802.11n despite the fact it wasn’t an extended network and it was obviously slower than the 802.11ac router which is only slightly further away. This slashed my connection speed by roughly 90% as everything was routed through the bridged connection.

The solution I’ve put in place was to give the 5GHz network a different name on my Airport Extreme. I’ve configured all of my Airport Express cards and Apple TVs to connect to the 2.4GHz network and all my regular devices connect to the 5GHz. There is now no danger of my MacBook accidentally connecting to an extended network but AirPlay still works like a dream.

If you notice you’ve got a slower connection since upgrading to Yosemite, it might be worth taking a look if any AirPlay devices are to blame!

October LEGO Updates

I’ve been meaning to write a couple of LEGO updates this month as there is so much cool stuff being unveiled. In the end I decided to do it as one big post…

Slave I

A video was released from the LEGO Design team showing off the latest UCS Star Wars set coming in January; Boba Fett’s iconic ship Slave I.

This looks like an absolutely fantastic set with a lot of cool features, the standard UCS stand, and (best of all) a Han Solo frozen in Carbonite!1 The Slave I is showing on the LEGO Website as being available on 1st Jan 2015 and consists of 1996 pieces. UCS sets like this are usually made available to VIP members a couple of weeks before but I’m not sure if that will happen with it being Christmas.

Speaking of Christmas…

Christmas LEGO

All of the LEGO Christmas sets are now available including Santa’s Workshop. Throughout October there are double points for VIP members and if you spend over £50 you get an exclusive Toy Workshop. I’m quite tempted by the workshop and a few baubles for the tree!

LEGO Santa's Workshop

The Hobbit

Today saw the release of 4 new sets in ‘The Hobbit’ series. These range from the small Witch-king Battle to the largest Hobbit set yet with The Lonely Mountain (complete with Smaug). As with the previous 5 sets, there is something about these I’m just not keen on. I loved the Lord of the Rings sets so much that I bought all of them but there’s something about The Hobbit which doesn’t grab me in the same way. The Lonely Mountain set is also very expensive (most likely to cover the cost of Smaug) at £99.99 for less than 900 pieces.

LEGO The Hobbit: The Lonely Mountain

Jurassic (Park) World

One of the more exciting announcements last week is that Universal have confirmed LEGO will be a licensing partner for Jurassic World, the new Jurassic Park movie due next year. When I collected the LEGO Dino series a few years ago, I thought it would be much better as a licensed Jurassic Park set and it seems that dream has come true. I’m hoping this will go hand in hand with a Jurassic Park LEGO game from Telltale with all 4 films. If the sets go down well, I’m fairly sure they’ll do some of the classic scenes from the original 3 films.

Blocks Magazine

Finally, Blocks magazine (which I’ve raved about before) becomes a monthly magazine starting next week. If you order an annual subscription, they’re sending out a really cool minifigure of the editor complete with a tiny pilot issue of the magazine. Mine arrived today and I can’t wait for the magazine to come next week!

Blocks Magazine Subscription Limited Edition Minifigure

That pretty much sums up the exciting LEGO announcements so far this month. My LEGO room still in the process of being setup after moving house and I have these sets to finish:

  1. This was originally in 9516 Jabba’s Palace and almost tempted me into buying that incredibly overpriced set (I’m glad I didn’t in the end) ↩︎

‘No results found’ on iTunes Artwork Finder

My iTunes Artwork Finder has proven very popular over the last couple of years. The issue with popularity is that the amount of correspondence increases. In the past two years, the top requests via email have been:

  1. Support for a specific country
  2. Asking for artwork of a specific show or film

I fixed the first a little while ago by automatically listing all of the iTunes countries but the second continues to be a constant issue in my inbox.

The way the finder works is to use the iTunes Search API to find the item you are interested in and then retrieve the artwork. This basically means that if the item isn’t on iTunes1, this tool won’t find the artwork for you. If you email me asking for a specific show or movie cover, I can’t help you.2

To try and limit the amount of email I get like this, I put in a disclaimer on the website. This got buried at the bottom of the page when I had a redesign so now I’ve added a note within the results.

"No results found" on iTunes Artwork Finder

Hopefully that should work!

  1. It might that a film hasn’t been released yet, the TV show is only on Netflix, or there is some other reason why iTunes doesn’t stock the film, show, or album you are looking for. ↩︎

  2. I will generally use Subler or Google Image Search if the iTunes Artwork Finder comes up blank. ↩︎

The problem with Allow Full Access on iOS 8 keyboards

I’ve never had a desire to change the stock keyboard on iOS. When the announcement was made at WWDC 2014, I thought that it was an interesting feature, but not one I would ever want to use. That changed when I saw the teaser page for PopKey, a keyboard that allowed you to paste animated GIFs straight into your conversations. That made me think about keyboards in a different way and how developers might create interesting keyboards that aren’t just improved ways of typing1.

As it turns out, PopKey isn’t very good. It doesn’t have search, watermarks the images, requires you to create an account and give over your phone number, and it was beaten by Riffsy which is actually better2.

Anyway, the problem I’ve seen over and over again is that these keyboards require “Full Access”. This is a feature that basically enables the keyboard to talk to its host app and to the internet. The reason you might want this for a keyboard is that it might do auto-correct (iOS 8 keyboards do not have access to the Apple auto-correct algorithms) and therefore does some processing in an app or in the cloud. With Riffsy and PopKey, this is obviously required in order that it can download the GIFs from the internet. The real issue isn’t that it requires this access, but that Apple puts up this message when you enable it:

Allow Full Access dialogue on iOS 8

“This could include sensitive information such as your credit card number or street address” - could they make that sound any scarier?

I’ve seen numerous people tweeting at PopKey asking them why it requires this access and how they won’t use the app until that requirement is turned off (which obviously won’t work - it needs internet access). I engaged a few in conversation and, even after I explained how it worked, the message I got back was “I don’t trust it”. I’ve even chatted to a few iOS developers who refuse to install a GIF keyboard because of that warning!

The basic problem is that the alert message you see is almost too scary and doesn’t give enough information. It was obviously written for what Apple expected; text keyboards. I’m not sure of a complete solution but as a start it needs to make it clearer that only things you type in that keyboard can be (potentially) seen by the developer. You don’t type anything in a GIF keyboard so the developers, if they are logging everything, can only see what stupid images you are sending. In addition, 3rd party apps can block custom keyboards from showing on sensitive screens (i.e. when entering your master password in 1Password or entering your pin in a banking app) and password fields automatically disable 3rd party apps (try it in Safari to see).

It is developers that will suffer for this. End users are already up in arms about privacy and demanding keyboards not use this feature whilst clients don’t necessarily understand what is going on and just see the negative feedback. I’ve been approached by a number of prospective clients to build these keyboards and so far I’ve put them off by showing them the ‘Full Keyboard Access’ search on Twitter.3

It seems to me to that Apple are treating the keyboard as a power feature and expect people to understand how it works under the hood. Seeing as some security savvy developers are cautious about installing these things, I think Apple has a lot of improvements to make in the way keyboards are installed, especially if it is to avoid negative fallout from end users who think that developers can steal your credit card number with an emoji keyboard. It’s good to be cautious about these things, but at the moment people are completely paranoid due to the installation process.

  1. That is if you call swiping an improvement. Sidenote: I hate that since iOS 8 a lot of people misspell the verb ‘swipe’ as ‘swype’ (as in “I can’t swype through this page in your app”) ↩︎

  2. It irritates me that PopKey is the more well known keyboard though. This is entirely due to the fact that it put up a really nicely designed teaser page in advance and has got a lot of press coverage. I think it is really bad they still use the tagline “The world’s first animated GIF keyboard” when it clearly wasn’t and has so many flaws compared to the app that came first. That it is featured by Apple in the Best New Apps section is a great shame. ↩︎

  3. For a while I tried to educate people as to how a GIF keyboard can’t read your iMessages. I gave up after a while. ↩︎

Showing TODO as a warning in a Swift Xcode project

I rarely use comments when I’m coding1. I do make one exception though; using // TODO: and // FIXME: to highlight pieces of code I need to revisit at a later date. The advantage of doing this is that the lines then show up in the jump bar popover in bold text with one-click access to the exact line:

TODO comments in the Xcode jump bar

The issue I have with this is that it is very easy to forget about them unless you are using the jump bar frequently. I used to log them in my todo manager, Things, but that duplicates the workload. It would be much more useful if those errors were flagged in some way…

Jeffrey Sambells wrote a post on how to flag these comments as Xcode warnings but that only applies for Objective-C. With a slight tweak, here is a run script build phase for flagging TODO: and FIXME: as warnings in a Swift project:

TAGS="TODO:|FIXME:"
echo "searching ${SRCROOT} for ${TAGS}"
find "${SRCROOT}" \( -name "*.swift" \) -print0 | xargs -0 egrep --with-filename --line-number --only-matching "($TAGS).*\$" | perl -p -e "s/($TAGS)/ warning: \$1/"

The result is an unmissable warning whenever you run your project.

TODO warnings in an Xcode Swift project

I don’t know about you, but I feel more compelled to clean up these yellow warnings than ticking things off in a todo list.

  1. If your code needs commenting, it isn’t clear enough. Refactor until it is. If it doesn’t make sense because of semantics, rethink your naming conventions. ↩︎

Donating blood

I’ve been donating blood for just over 10 years and went for my quarterly donation yesterday. If you don’t donate already, please consider finding your nearest donor session and donating - most donations are done with a mobile team and are likely to be in a village hall or similar. It is a fairly quick and painless process and the National Blood Service is always in need of regular supplies for transplants and cancer treatment1. Not only do you get to save lives and have your blood screened for anything dangeous, you also get a cup of tea and some biscuits afterwards.

Take a look at the National Blood Service website to learn more and find your nearest donor session.

  1. Especially if you have a rare blood type. I’m AB- which has the smallest amount of stock in the national blood bank↩︎

Private lives

This weekend the news broke that Brooks Newmark had resigned from the government due to a sting by the Sunday Mirror. A journalist posed as a young female Conservative activist and they ended up flirting via Whatsapp with him eventually sending some lewd photos.

To my mind, this is a fairly simple case of entrapment with a journalist pretending to be somebody in order to get a gossip story for a newspaper. This does not require a resignation and is a further indication of what is wrong with our politics; MPs are not held to account the same as regular people.

If you worked on the checkout in ASDA and you started flirting with someone on Whatsapp despite being married, you don’t have to resign when everybody finds out. However, you do have to resign if you take money from the till1.

So it should be for MPs. They are regular people and they shouldn’t have to give up their career for stupid things they have done in their private lives that are totally legal. The argument “he lied to his wife so what stops him lying to voters” is idiotic; unless there is proof that his private life is affecting his work, then it is certainly not in the public interest.

If an MP or any other public figure is doing something illegal, then it is fair to hold them to account. It is not fair to use their private life especially if they have been manipulated into it.

  1. Well, you’d be sacked actually. ↩︎

IslandBreak

I’m happy to announce that an app I worked on earlier this year has finally gone live on the App Store; IslandBreak.

IslandBreak for iPhone

IslandBreak is a smart travel guide for the Bahamas with a complete list of restaurants, bars, historical sites, hotels, beaches, and tours.

The app was interesting to work on due to the need for a completely offline experience. This wasn’t limited to just the points of interest and itineraries (which feature a huge amount of beautiful high-resolution photos) but also the map; this was a requirement so that tourists don’t have to use their data plans, particularly in an area which has very poor mobile reception1. Getting a full map of the islands complete with multiple zoom levels and the experience you expect on iOS was difficult, but works really well. In addition, I built an online CMS so that the app content can be updated remotely without going through the App Store approval process.

You can check it out by downloading from the App Store (currently priced at $0.99) or visiting islandbreakapp.com

  1. I speak from experience. I’ve been to the Bahamas a few times and proposed to my wife there; we had to wait until we were back in Florida before we could share the news! ↩︎

iOS using internal reference name for IAP

Today I noticed a slightly worrying bug in iOS. In-App Purchases seem to be using the internal reference name rather than the localized display name. As an example here is my config for one of the consumable IAPs in WallaBee:

iTunes Connect Edit IAP Language

iTunes Connect Edit IAP Summary

The reference name is ‘v1.1 25000 Honeycombs’1 and the display name for UK English is ‘pack of 25000 honeycombs’. This means the purchase screen ends up looking like this:

iOS 8 IAP Display Name incorrect

Hardly ideal.

I double checked the In-App Purchase Configuration Guide and it still states that:

In the Reference Name field, enter an internal name for the product.

I’ve not been able to see this in other apps as most people will use the same display name and reference name. I’ve reported a bug with the Apple Bug Reporter Filed as 18454842.

You may want to check your own IAPs to make sure the reference name looks ok until this gets fixed. You can change them without going through App Review (as they aren’t supposed to be visible to end users).

Update (26th September 2014): Tony McBride emailed me to say that he was experiencing the same issues on iOS 7 building against the iOS 7 SDK. I’ve confirmed it is happening in WallaBee v1.4.1 (built with iOS 8 SDK) running on iOS 7. Looks like it may be an App Store issue rather than an iOS 8 issue. I’ve updated this post to remove references to it being a solely iOS 8 problem.

  1. In case you are wondering why, I forget exactly. I think there were different packs in v1.0 which we then increased in v1.1 - some of the increases overlapped (i.e. 15000 became 25000) and so I had to use a different name. Prepending the version seemed to be a sensible choice as nobody would see it. ↩︎

How not to deliver a speech

Yesterday, Ed Miliband delivered his speech to the Labour Party conference but embarrassingly left out a large portion about one of the most important topics of this decade; the budget defecit1.

I’ve given quite a few speeches in the past and often give out advice to people (mainly developers) who are preparing to give a presentation or some form of pitch. The two key pieces of advice I always give out are:

  1. Don’t write your speech
  2. Don’t use notes.

In my opinion, you should never write a speech out in full. To do this means you are then locked in and can’t adapt to a changing situation. This is especially true if you are doing a speech in which you have to follow someone, something goes wrong2, or you are talking about things that could change. Additionally, I don’t believe in using notes. Nobody wants to see their presenter looking down at a little card, or worse, a mobile phone. If you are going to use notes, keep them discreetly on a table and only consult them whilst your audience is applauding or laughing (if they are doing neither, change your speech). They should also be only the loosest of bullet points to keep you on track.

Ed made a mistake by breaking both of these rules badly. He wrote a speech but then made changes at the 11th hour (about the Scottish referendum) making it harder to memorise; he also (very stupidly) distributed the speech in advance so it was obvious when he had left something out. Finally, he had notes printed on thin paper through a clear table; easy for anybody with a camera (i.e. the national press in the front row at a political conference) to see and know when you’ve missed something.

There are a couple of exceptions to these rules:

  • If you are doing a presentation which includes some form of slideshow software, this is a lot easier as the bullet point skeleton is already written for you. You don’t need any notes, just be sure to scan over the upcoming slide whilst you are talking and be ready to speak around that subject. Never repeat what is written on a slide (which should be sparse) unless it is a quote. Any presentation by Apple is a great example of how to do this incredibly well.

  • If you are delivering a eulogy, these rules do not apply. You should have it written in full and printed to read from. Never give a eulogy from memory.

The key thing with any speech or presentation is to sound authentic. To do that, I believe you have to connect directly with an audience and not rely on remembering huge passages of text. It is much easier to have a few loose bullet points in your mind and then flesh it out as you are presenting.

In the end, a speech is simply a one-way conversation with multiple people. Imagine you are telling a friend about the thing you are speaking on and everything should fall into place easily. If you try to remember an essay, then the speech will be difficult to remember, uncomfortable to watch, and far more likely to go wrong.

  1. You could say he had a defecit in his speech *rimshot* ↩︎

  2. My favourite example of this is the original iPhone launch. Towards the end of the presentation, Steve Job’s ‘clicker’ broke so he couldn’t advance the presentation. Whilst he was waiting for it to be fixed, he told a brilliant anecdote about Steve Wozniak jamming televisions when they were younger. The whole delivery was natural and unscripted and he was able to recover straight back to talking about predicted market share - you can’t do that when you are leaning heavily on memory nor a text-heavy presentation. ↩︎
