A quite legitimate criticism of iOS for some time has been the fact that you seem to end up with multiple gigabytes of unexplained “other” disk space usage after using the device for some time. It’s frustrating, especially on smaller devices.

Reinstalling iOS and restoring from your most recent backup would clear the mythical “other”, at least for a while.

It seems that the latest update to iOS, version 10.3, introduces a whole new filesystem technology, APFS. This wasn’t mentioned in the release notes, and is only really detectable by the end user in the form of a much longer upgrade process than would be needed for a typical iOS release.

Since upgrading a few devices, I have noticed a big jump in the available free space on those devices. The pesky “other” is still there, but appears to have shrunk significantly.

Hats of to Apple for fixing what was a criticism going a long way back, and for managing a quite potentially disruptive filesystem migration in such a transparent way for the end user.

May the “other” space usage forever remain small.

The Pushover Simple Notification Service

I’m a huge fan of the Pushover Simple Notification Service for receiving critical alerts about the servers for which I am responsible. It’s beautifully simple — in short, it takes the ‘walled garden’ of Google or Apple’s push notification system and extends it, so that you can push any text notification you want through their API, and it’ll get to your phone.

In this post, I will share how I get critical alerts from a Microsoft System Center Operations Manager instance to Pushover.

Ever since updating my iPhone to iOS 5, I was unable to complete a sync.

It backed up fine (thankfully), it did the majority of the syncing, it just got to the last ‘stage’ of the process and hung there perpetually. I saw messages such as “Waiting for items to copy”, “Waiting for changes to be applied” and so on.

It wasn’t a complete showstopper, since I could sync the majority of content, make sure I was backed up, and then just cancel the sync at the last stage, but it was something that needed a fix.

I had read various threads on Apple Support Communities — it seems that many people are having this issue.

I get the impression that this symptom is caused by various syncing issues and that some solutions have worked for some people, and not for others. Bear this in mind — this solution worked for me, but it might not work in every case. 🙁

I believe I have now solved this problem on my iPhone.

Delete All Copies of Voice Memos

I deleted all of the synced Voice Memos in my iTunes library, then also went into the Voice Memos app on the iPhone and deleted each and every one there. Upon the next sync, the locking up at “Waiting for items to copy” did not happen, and the sync completed successfully.

This suggests that one of the causes for this issue is Voice Memos. If you are experiencing this issue, try backing up and removing all the Voice Memos from iTunes, removing them all from the Voice Memos app on the iPhone itself, then syncing again.

(The iPhone does still sync Genius Data each time it syncs, but this does complete successfully. Perhaps this is normal — I am not really sure!)

The upgrade from a first-generation iPod touch to an iPhone 4 is a significant one, in many ways. 🙂

If you haven’t seen the iPhone Retina Display, it genuinely is as good as the marketing suggests. No matter how close I hold the device to my eyes, I can’t make out individual pixels; the rendering of text is the best I have seen on any pixel display.

Other than the excellent additional hardware features of the iPhone, like the camera, GPS capabilities and of course, having internet access wherever I am, the other biggest upgrade is the sheer speed of the device compared to the first-gen hardware. The responsiveness of the UI on the iPhone 4 is as good as, if not better than, that of the iPad. Everything about the interface is fluid, responding immediately and directly to what you do. All the apps feel so much faster and it makes using the device a lot more natural when you aren’t waiting, even for a quarter of a second, for the next screen to load.

I’m very pleased with this as an upgrade to my mobile computing. 😀

The iAds feature in Apple’s iOS 4 has caused its fair share of controversy, and Apple’s privacy policy has just been updated to reflect the changes that iAds bring to the platform.

Notably, it is possible to opt out of iAds ‘cookies’, which means that the ads you see might be less relevant, but you are able to opt out from targeted advertising, which some people may be uncomfortable with (especially considering this functionality is built in across the OS and, presumably, the analytical data Apple gather from iAds would be shared across different apps).

Apple and its partners use cookies and other technologies in mobile advertising services to control the number of times you see a given ad, deliver ads that relate to your interests, and measure the effectiveness of ad campaigns. If you do not want to receive ads with this level of relevance on your mobile device, you can opt out by accessing the following link on your device: http://oo.apple.com. If you opt out, you will continue to receive the same number of mobile ads, but they may be less relevant because they will not be based on your interests. You may still see ads related to the content on a web page or in an application or based on other non-personal information. This opt-out applies only to Apple advertising services and does not affect interest-based advertising from other advertising networks.

I would encourage anyone upgrading to iOS 4 or purchasing a new iOS device to consider opting out of the iAd cookies, if they feel more comfortable knowing that the advertising is ‘dumb’ and not being targeted directly at them.

As the quote from the privacy policy says, all you have to do to opt out is visit http://oo.apple.com on each iOS 4 device where you want to opt out.
