ddDrumr – a drum machine in your browser

posted this on and tagged it with Daladevelop Links

Last weekend Daladevelop – in this case Mikael, Emil and I – spent 24 geeky hours in a house in Bjursås. The goal of every Daladevelop is to make program something great. Hitherto it has resulted in for example the WP Plugin Boilerplate and ”Pizzasugen”. This time it resulted in ddDrumr, a browser based drum machine prototype.

Since it’s awesome, I’ll advice you to try it! (You’ll need a really modern browser for it to work well.)

(Or, fork it on github,)

Markdown (The Greatest Invention Since Sliced Bread)

posted this on and tagged it with Blogging Markdown WordPress

Well, maybe I’m exaggerating a bit, but today (or yesterday since it’s passed midnight here) I did what I should have done long before and checked out Markdown. According to its creator John Gruber it’s

a text-to-HTML conversion tool for web writers. Markdown allows you to write using an easy-to-read, easy-to-write plain text format, then convert it to structurally valid XHTML (or HTML).

It is both a way to write plain text documents so that their content is somewhat formatted and a tool to convert this text to xhtml.

The reason I checked this out today (or was it yesterday?) was an article in Macworld called Forget fancy formatting: Why plain text is best. It made some good points about why plain text is almost always better than something written in for example Microsoft Word or Apple Pages.

[Plain text is] timeless. My grandchildren will be able to read a text file I create today, long after anybody can remember what the heck a .dotx file is.

The article then mentioned some tools that was great for plain text writing, among them Byword which according to the article ”has baked-in support for Markdown”. I’d heard about Markdown before, mostly from Merlin Mann in the Back To Work podcast so now I finally made myself find out what it was. (Finding out was as easy as clicking the link in the Macworld article.)

The concept behind Markdown seemed really great, so I decided to try it, and to buy Byword. So far I’ve just made some test documents with the Byword/Markdown combination (as well as writing this blog post) and I must say it seems pretty great. I do a whole lot of writing in my work and most of it is just simple text documents that I’ve used to write in Microsoft Word (yes, I actually do like Word) but I guess the bulk of my writing this upcoming semester will be done full-screen in Byword using Markdown and then exporting the appropriate format. (Apart from xhtml, Byword also exports as .doc, .pdf, .rtf and Latex.)

One more thing

I also found out that although Markdown is written in Perl there is a php version and that version also works as a WordPress plugin. So this very blogpost is written in Byword, marked up (or down?) with Markdown and will then be pasted into a post in my blog, where you will read it.

Hotmail works with Exchange

I just learned that a Hotmail account can be accessed via Microsoft Exchange and thereby getting a more IMAP-like functionality. To me, this makes Hotmail very useful as an iPhone Mail account.

Instagram’s great success

posted this on and tagged it with Links Social Networks

In just nine months, the photo-sharing startup hit 150 million pix and more than 7 million users who upload about 1.3 million photos daily (15 per second).

[…]

It took Flickr, one of the world’s largest photo-sharing sites, close to 2.5 years to reach 150 million photos, which could be uploaded from any computer and shot on any camera. But it took San Francisco-based startup Instagram roughly just nine months to hit that same milestone–with just one mobile app, available on just one device maker’s OS (Apple’s).

The interview and article is from FastCompany.com. The interview is good but I think the comparison between Instagram and Flickr that’s made by the author is unnecessary and incorrect.

Instagram has grown faster than flickr, that’s true, but I don’t think the comparison is very good. To me flickr is clearly a service aimed at photographers, amateurs and professionals alike. The users main focus is to show photos as art. Instagram is much more of a ”traditional” social network, but with images instead of text.

Just to clarify, I love Instagram and use it as a way of telling people I know about what I’m up to. I also love Flickr.

(Extra bonus irony-points to the article for using a picture from Flickr for illustration. Tough, I don’t think irony was what they were aiming for.)

This is the first picture I’ve taken with my new camera that I’m reasonable happy with. More will likely come.

A couple of great tips & tricks for Lion

posted this on and tagged it with Links

A personal favourite:

Lion’s new Resume feature automatically opens any application’s documents that were active when the app was quit. That can be jarring to people who traditionally quit an app when finished with a document. To ensure that a completed document does not automatically open the next time you launch the application, hold Option and choose [the Application Name] > Quit and Discard Windows, or press Command-Option-Q. Alternatively turn this feature off completely in the General system preference pane; you can then ensure that an open document does automatically open the next time you launch the application, again by holding Option as you quit the application.

My presence in various social networks

posted this on

Like so many other geeky people I’m a member of many social networks. The ones I actually use is twitter (@synvila), Instagram (mrhenko), Flickr (synvila) and Gowalla (mrhenko), and then there’s this blog. However, lately I think I’m starting to differentiate them in various ways and I’m seeing what I use each and every one of them for.

This blog is for longer or semi-long mostly tech related topics. It can also be links to techy things I find interesting and the occasional photo that I’ve taken. For this I use English as language. (Mostly American English.)

My tweets is almost always in Swedish. They also tend to be more or less geeky.

Instagram has really taken over twitter’s place as a network to tell people what I’m doing. It is quickly becoming my photo journal and if you’re interested in me as a whole person, not just as a geek, (although the geeky part is a pretty big part of me) this is where you should be following me.

Flickr is for my more or less ”ambitious” pictures. Here I post things that not necessary say anything about what I’m up to. It’s me pretending to be a photographer.

Gowalla is more or less dead to me. It feels a lot like last summers great romance. I still check in to places from time to time, but the check-ins are getting more and more far apart.

I’m using an old browser?

posted this on and tagged it with Browsers WordPress

I just picked up my secondary computer and logged in on this blog. The first thing I saw was WordPress telling me that I use an old browser. Since Safari 5.1 is out, apparently 5.0.5 is considered old. This is a fairly aggressive mode (I prefer to see things like IE6/7/8 and Firefox 3 as old) but I love it.

Good work WordPress! Anything that make people update their browsers more often is great.
