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.

Relaunching my blog

Five years ago I turned this site into a blog. I used Apple's iWeb software, thinking this would make it easier to update the site than crafting HTML by hand. And it was, for a while. But iWeb has been dead for quite some time.

So I decided to relaunch the blog using a homegrown content management system (this makes it sound a lot bigger than it really is, trust me). With this, it's easier to fire off quick posts or just link to somewhere else with a comment. The title of these posts starts with a →.

To avoid scaring people away with large swaths of text, the homepage just shows a short intro by default. You have to click on the red triangle to expand the full text of a post in place. Because the text is already loaded, you'll see it immediately. You can of course also click on the title to see the post on a separate page.

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.

Having fun with invisible ink

A month ago, I got a message from the OHM2013 speakerdesk:

Since you you'll be giving a presentation, lecture or workshop at OHM2013 (for grownups), we'd like to ask you; do you feel like giving a little talk about your subject for kids?

Thinking that my talk (about federation of online services, where you can have a choice of service providers or even run your own server rather than be beholden to big companies like Google, Facebook and Twitter (PDF of the slides, explanation in Dutch) might be a tad too abstract for kids age 6 - 10, I proposed something else instead: writing secret messages in invisible ink.

→ 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'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.

Radio Kootwijk gebouw A

This weekend, I was in the neighborhood of Radio Kootwijk, so I took advantage of that opportunity to take some photos of Radio Kootwijk gebouw A ("building A"). This is the site of a big shortwave radio transmitter that allowed the Netherlands to keep in contact with Indonesia, which was a colony of the Netherlands at that time. The time being the 1920s. I love this kind of art deco architecture.

2013, a good MacBook Pro year?

I bought Apple laptops in 2002, 2003, 2007, 2008 and 2011. So that's one every two years on average. In 2008, I learned the hard way that I really need to have a decent backup computer in case my primary one fails. So a while back I decided that I should probably buy a new computer every two years, and keep the previous one as a backup for another two years. So I'm due for a new laptop this year.

Which brings up the question: is 2013 a good year for buying a new Mac laptop?

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.
