There’s been a lot of debate among web professionals about whether or not it makes sense to server “retina” images to website visitors who’s devices support high pixel densities. In order to take full advantage of the sharpness of the new iPad’s screen, website owners would need to prepare their images at four times the number of pixels of normal (“72dpi”) web images.

I ran a few quick tests to see how much all those extra pixels affected overall file size. I used 130 randomly chosen jpeg images (all straight from my DSLR camera), and ran Photoshop and Irfanview batches to crop and scale them to a couple of often-used sizes. I used the same JPEG settings each time, and made sure the only difference between the images would be that the retina ones were four times sharper.

Last night’s WordPress meetup in Amersfoort was, at least as far as I’m concerned, a resounding success. Around 70 people attended, and we had a lot of interesting speakers. Most of the presentations were captured on video, and will be placed online later. For now, I’ve put the snapshots I managed to take on Flickr for you. Enjoy!

I’ve also created a Flickr pool for Dutch meetup images. Please feel free to add you pics there. I’m still pretty new to Flickr, but I think I allowed everyone to contribute…

Recently, Picasa started serving its RSS feeds over https. From what I can tell, this has caused quite a view “clients” to fail. Digital photo frames seem to be affected, and so is my Flickr widget. Fortunately, there’s a quick fix.

I’ve run a few tests, and it seems that simply removing the “s” from “https” fixes the issue. Every feed I tried could be called up over regular old http as well, and all of them worked with my widget.

The great thing about WordPress is that there’s a huge, active and helpful community of users and developers. There have been WordCamps organized all of the world, as well as many smaller meetups. Last week, Kaj Rietberg and I put together just such a meetup in the Dutch city of Amersfoort.

The event was sponsored by open source development company 4WORX and hosted at the neighboring Dara restaurant (recommended!). Kaj and I were happy to welcome around 25 WordPress enthusiasts, a couple of whom had been tricked beforehand into preparing presentations. Kaj has written a more detailed account over at the WordCampNL website (in Dutch) which includes the slides from two speakers.

I used to be a real nitpicker when it came to preparing images for the web. I’d laugh at people using large images in web pages, showing them in a smaller format by setting the width and height properties.

In the days before broadband was everywhere it was bad karma to do this, because a large image file would take a long time to download. You needed to prepare the image at the size you were going to be displaying it. Nowadays, things are a little different.

When I first heard about gdgt.com, I thought the startup founded by Peter Rojas and Ryan Block was terribly clever, and right up my alley. The idea of having gadget freaks keep “had”, “have” and “want” lists makes sense both from a user’s perspective and from an advertiser’s. When the website opened to the public I was quick to register and started adding things to my lists. Some stuff that wasn’t in there yet. It was amazing to see how much stuff was entered by users.

But I don’t buy a new gadget every day, so keeping the lists up-to-date doesn’t require me to visit GDGT daily. Considering how Rojas and Block were also involved in Engadget and Gizmodo, I was hoping their new effort would replace both those blogs and become a one-stop shop for technology enthusiasts. So far, at least for me, it hasn’t.

Twitter by it’s very nature is a very limited service. That’s what’s fun about it. Some people manage to be really clever and witty in 140 characters. But there’s only so much you can express in a tweet. The other main way to express your personality on Twitter is through your avatar image (or ‘profile picture’ as Twitter calls them).

Many of the people I follow have carefully designed avatars that they don’t change very often. But what if you could have your avatar be as current as your tweets. Showing you exactly the way you look today, doing what you’re doing right now? That’s where Snapatar comes in.

I came across this post on Smashing Magazine yesterday, and while it offers some fine reasons for web developers to use a PC, I thought it missed a few too. Most of these venture into web designer territory somewhat, but I wanted to mention them nontheless.

I’d been meaning to do a proper redesign of this blog for some time. The content part was reshuffled a couple of months ago, and I was pretty pleased with how that turned out. But the header was a watered down version of the old Papertrail theme and far too boring. That’s why I asked Blondmonster to help me out.

Suzanne‘s a former colleague, and a fabulous designer. I really like the stuff she does, and ‘boring’ is simply not in her vocabulary. She came up with the underwater theme, did all the drawing and all I had to do was put it all together. Hope you like the result. The theme was tailor-made for this blog, so don’t expect it to become available for download any time soon.

Talk about picking a poor name for this project. I first considered giving it a catchy name, but decided to simply call it ‘Flickr widget’ becaused that best describes what it does. But then I found that Flickr itself has a Flash widget too. And now I’ve made it support Picasa feeds too, so the name doesn’t make any sense anymore.

The upside is of course that Picasa users can now use the widget to show off their favorite albums on their websites. It accepts the feeds from your ‘My Photos’ page and album pages. If you, like me, have only a couple of albums under ‘My Photos’, the feed from that page will only show the album covers, so it makes more sense to use an album feed (on the left is a trip to the zoo with my daughter in 2007). Like with Flickr, the total number of thumbs shown is limited to 20.

Fortunately, Google uses a very similar feed format to Flickr, so I was able to put support for both into one Flash movie. Please feel free to try it, and let me know if you run into anything.
