Buying a USB 3 - Gigabit Ethernet adapter

When I get the new computer, I guess I'll have to buy a second GE adapter so I can transfer data between the two computers at the highest possible speed. There are now 10/100/1000 Ethernet - USB3 adapters. Those should give me full GE performance on the new computer that will have USB3, but in the meantime something better than wifi using USB2 on my current machine.

→ Have iPhone, will travel—without a data plan

It's that time of year when people tend to go on vacation, and although data roaming in Europe is now slightly less expensive, it's still not cheap, so here's a link to my Ars Technica story on how to use your iPhone without a data plan.

No more Google Reader = anonymous searching

It just occurs to me that Google may have shot itself in the foot by discontinuing its Google Reader RSS reader service, because now more people will do their Google searching without being logged in.

My OHM2013 talk: Federation fosters freedom

Between 31 july and 4 august OHM2013 ("Observe. Hack. Make.") will take place in Holland. I'll have a talk on the 4th at 16.00 about how network protocols that let you run your own server foster freedom, while monolithic services such as Facebook and Twitter do the opposite.

iOS 7, new iPhone screen sizes and insta-deletion

Decisions, decisions: update your iOS apps now for iOS 7 and be ready on day one, or wait until new iPhones and iPads arrive and incorporate support for a possible new screen size/resolution in the update?

Caching PHP-generated pages

For years, I always used to include an If-Modified-Since header in my PHP scripts in order to allow their output to be cached by web brow­sers. Turns out, it takes a bit more work.

→ iOS 7: watershed moment

Gedeon Maheux of the Iconfactory makes the point that it takes a lot of developer time to create new versions of apps and then asks:

how willing would you be to re-purchase your favorite apps if they are optimized for iOS 7? Look at your device’s home screen and go down the list of apps you use most and ask yourself if you could live without it once you upgrade. I think that most users (at least those that matter to de­velop­ers) would answer that they would gladly pay again if it means having the latest and greatest version of their favorite apps, at least I would hope so.

I hope so too. I would much rather pay for new iOS 7 optimized versions of my favorite apps than be stuck halfway there because of lack of time/money to do the work to get fully on board with iOS 7 and/or the need to keep supporting iOS 6.

→ Deleting zombie photos from iPhoto

Recently I noticed when I delete photos from the iPhoto trash, iPhoto doesn't necessarily delete the image files from its library. My iPhoto library is the single biggest thing on my MacBook Air's hard drive, and it's the reason I had to pay extra for a 256GB SDD rather than use the stock 128GB one. I'm in the habit of taking a bunch of shots of every subject to make sure at least one has the correct focus, exposure, and is level. All this is to say I have a lot of extra photos that I need to get rid of.

But as I noticed, sometimes iPhoto doesn't delete photos when you empty the iPhoto trash. It just removes them from its database so they're no longer visible without deleting the actual image files. Those files still use up disk space—to the tune of 10 GB in my case.

So, after a little tinkering, here's how to get rid of those unwanted photos and reclaim that disk space in eight easy steps.

→ Apple using Multipath TCP for Siri

According to Olivier Bonaventure, Apple is using Multipath TCP (MPTCP) so that iOS 7 devices can communicate with the Siri servers over both Wi-Fi and 3G/LTE at the same time. If you want some background, see this article in the IETF Journal about MPTCP that I wrote in 2009.

Apple's iPhone 5s dock

When the iPhone 5 was released last year, Apple didn't bother with any cases or docks. Third parties certainly addressed the lack of cases, but as far as I can tell, there were never any good docks. But now there's the iPhone 5s dock, which is also compatible with the iPhone 5. So I got on my bicycle and went to the nearest Apple Store to get one. Read on to see if it was worth € 29 and cycling 63 km.

→ Multipath TCP lets Siri seamlessly switch between Wi-Fi and 3G/LTE

In the past, Google has created alternatives to widely used networking protocols such as SPDY in order to deliver search results as fast as possible. Apple is now doing something similar by having Siri use Multipath Transmission Control Protocol (MPTCP). MPTCP is an extension to the TCP protocol that's used for about 85 percent of all Internet traffic. Generally, it allows TCP to operate over multiple paths at the same time. However, Apple seems to use MPTCP for one very specific purpose: to allow Siri to switch between Wi-Fi and 3G or LTE as quickly and seamlessly as possible.

My advice to podcast app developers

Archiving data: DVDs, flash drives, hard drives?

Originally, I intended to write a story under the title "saying goodbye to the optical drive". But after a few minutes of research, it turns out that, in my particular case, the optical drive may be on its way out, but it hasn't quite left the premises yet, and not just because I may need to rip a DVD or CD once or twice a year. Let me tell you a tale of backups and storage management.

NL-Alert on the iPhone

The Dutch government has an emergency alert system called NL-Alert. With this, they can send alerts to all cell phones in a region using the cell broadcast feature. So unlike SMS messages, everyone who has them enabled in the deployed region gets them immediately, even if the network is otherwise congested and without the government knowing the phone numbers in question.

As of iOS 7 the iPhone can now receive these alerts, as you can see with today's test in this Youtube video.

About that third-party lightning cable for my iPhone

Last month I posted a picture of the lightning cable I got for € 6.29 at my local super market—a third of what Apple charges.

At first, it seemed to work well except for this warning that pops up when I connect it to my iPhone 5...
