There are a lot of people who think camera’s in tablets are a bad idea. “Nobody should be allowed to take pictures with a large tablet in front of their face.”
But if you can think outside of the traditional camera box for a moment, and start to think what’s possible if you combine a really portable computer with a decent camera, you’ll soon see interesting new possibilities.
Just a couple examples:
While converting my old wordpress blogposts to markdown i read some of my old
posts. For example, here is what i wrote when Apple launched the iPhone in 2007:
In a couple of years mobile phones will be powerful enough to replace
laptops for most common computing usages. You won’t need a separate laptop.
You walk around with your mobile phone, in the office or at home you put it
in a docking station, attach a keyboard and a bigger display, and you have
all the computing power you need.
Some news this last week indicates we’re getting close (more...)

I’m a slow mover here, far behind the hype-curve, but this blog is currently being moved to jekyll. The following are some notes and links from this process.
Reasons to migrate:
- Cheaper hosting - this blog is currently hosted on DreamHost. By migrating to a static site using Jekyll, cheaper options become available, for example Amazon S3 or Github.
- Learn something new -10 years ago this blog started on Moveable Type, which also generated static html pages. In 10 years we’ve gone from full dynamic back to static, mostely thanks to javascript. The dynamic parts in many (more...)
Mostly a reminder to myself, as this looks interesting for my SVG
presentation tool.
I’m currently creating a Prezi/Html5/SVG/onionskinning/blackboard kind
of presentation tool, and it seems like SVG has native support for some
of the code i’ve been writing: SVG fragement identifiers and SVG
view element.
The linking i’ve currently implemented using the html5 history api.
Views are currently implemented using javascript arrays containing
references to SVG group elements, where i modify the viewport of the
svg element to match a specific rectangle. Seems like i can rewrite that
code.
In iOS Safari you can add web applications to the Home Screen (Add to
Home Screen). When you open the web application by selecting the icon
placed on you Home Screen, Safari will try to use cached resources to
display the web application. To control this caching you need to
understand the Html 5 application cache.
Html 5 apps can specify which resources can be cached on the client to
enable offline usage of the web application. You do this using the cache
manifest file. This is a text file, served with the mime-type
text/cache-manifest. The filename usually has the (more...)
Every time you mention doing data centric business logic in an Oracle
database using pl/sql, the first reaction you’ll get from java/jee
developers is that it’s evil. Code and business logic should be placed
in the java based middleware.
PostgreSQL 9.2 was just released, and one of the new features is
json and javascript support in the database. And somehow, developers
find this an interesting feature:
Combined with the new PL/V8 Javascript and PL/Coffee database
programming extensions, and the optional HStore key-value store, users
can now utilize PostgreSQL like a “NoSQL” document database.
I agree that it’s (more...)
Enable new relic on your app, either using the web interface, or in your

Recently, a number of books have been published that aim to improve the
quality of your presentations: Beyond Bullet Points, Presentation
Zen, Slide:ology and Resonate.
Unfortunately, presentation software hasn’t really improved to help you
create presentations in the way suggested by these books. Their core
functionality is stil focussed on writing bullet points and presenting
these to your audience.
Haiku Deck is the first presentation software I’ve seen that is
really focussed on helping you create visual support for your
presentation. Slides consist of a title, maybe some supporting text, but
most importantly, an image to illustrate the (more...)
At least for me it’s turning into infrastructure more and more lately.
And i guess this is true for more people. And twitter doesn’t like it,
so that’s why they announced their API changes. But people don’t
like it, because Twitter is infrastructure…
I hardly use the twitter app or their website. Mostly i use it in
Zite, to find interesting articles to read, and to promote articles
i like. And also in instapaper and Pocket.
Twitter is the infrastructure that enables these apps to display great
content. Replacing twitter with Google+ or app.net shouldn’t be
too hard…
