Wiki Tips and Tricks

How can I easily link to Wikipedia?

PmWiki supports linking to Wikipedia quite easily actually, it’s the same markup (more or less) as a standard link in PmWiki’s markup: When I write Mac software, I use [[Wikipedia:Core Data | Core Data]] and [[Wikipedia:Cocoa (API)]]

When I write Mac software, I use Core Data and Wikipedia:Cocoa

How can I add one of those cool post-it notes to a page?

Post-It notes are thanks to the PostItNotes recipe fron the PmWiki cookbook. To learn how to use PostItNotes? more extensively, check out the PostItNotes page. To use a simple note use the following syntax:(:note Alert! | This is a simple note! 🙂

You can also create “hidden notes” that will merely display the title, and then once clicked, reveal their contents:(:notehidden Top Secret! | Aliens really do exist! Ruh roh! 🙂

Fancy notes are just as simple by using the following syntax:(:notefancy Alert, my good sir | This is a much fancier, but still relatively simple note 🙂

Rumour has it you can embed RSS feeds into pages as well

Via the PmFeed recipe, you can embed an RSS feed into any wiki page you like, for example, your personal page.(:pmfeed max_count=3 showitemdescr=false feed=’’:)

Error: It’s not possible to reach RSS file …

How can I embed source code into my page?

Thanks to the SourceBlock recipe, you can embed coloured code into a wiki page: (:source lang=c:)
int main(int argc, char **argv) {
std::cout << “Hi Mom!\n”;
return 0;

To end the source block, use (:sourceend:)[Get Code]int main(int argc, char **argv) {
    std::cout << “Hi Mom!\n“;
    return 0;

How does tagging work with this wiki?

Via the Tags recipe, it’s possible to tag newly created, and already existing wiki pages. All that needs to be done, is at the bottom of a page add: (:tags cocoa, tipsandtricks, exampletag 🙂
cocoa, tipsandtricks, exampletag,

And as you can see, when you click on these tags, it will bring up a page of all the similarly tagged pages. Nifty! 

I like the Frappr Map, can I use that in any page I want?

But of course  The Frappr map has been added to PmWiki’s custom markup and you can embed it into any page using the following: (:frappr:)

Cocoa Dev House Amsterdam

Next CocoaDevHouse in Amsterdam(?)

A lot of new cool Cocoa stuff has emerged from Apple since the last CocoaDevHouse in Amsterdam. Time to organize a new event? Is there interest for such an event to take place some time in early 2015?

About the previous CocoaDevHouse event:

Video Podcast Online…

I finally extracted the content of my video camera to produce a pretty long Video of Cocoa Dev House Amsterdam… Check it out directly in iTunes and write your comments at ! StuFF? mc.

Attention Please! (update)

An update on the RFID project we built during CCDHA. Today is the big day when the thing we made (a combination of a WebObjects? backend and two RFID client applications) is being used for real. A few last minute hiccups (like XCode? only producing Intel versions of everything and trying to then run them on PowerPCs?) but its hacked up and holding together with style. Katie is documenting the whole thing on Flickr and the Attention Please site so check ’em out.

Again huge thanks to everyone who helped, especially Axel the AttentionSeeker?.app and Johan the AttentionGrabber?.app

It’s Over!

A massive thank you from Katie to all CocoaDevHouseAmsterdam attendees who made the event fabulous. I had fun, hope you all did too. We had about 40 people in total (many people came by Friday night) and the hardcore crew of 16 or so were there till 2am Sunday, plus of course the guys in the backchannel.

So what did we make and do? Well the grand achievement of being a Flickr hot tag obviously. More updates will come here; I know Paul is tweaking the Cocoa RFID app he, Dirk, Axel, Johan and Abizer made. To be continued…


Tshirts from CocoaDevHouseAmsterdam are still available. If you’d like one, we can ship them anywhere so just PayPal? EUR15? to and tell us your address. Picture of Tshirt on Model!


So we’re going to start back at 10am ish. The lovely Nadya has the keys and we agreed, 10, well maybe 10.30. Seeing as we only left at 2, that’s pretty good going! If you Amsterdammers are keener than this, get a coffee or something…


Get to Centraal Station. As you come out of the Station turn left and look for the large building site. One of the buildings just has POST CS written in big, can’t miss it. CCDHA is located in the bottom floor of that building. Just head towards it and follow the signs for POST CS, Restaurant 11 and Stadelijk Museum.

If you need any bits of kit theres an apple center just across from Centraal

Getting there early? Just come by whenever you arrive, people will be around, arriving and getting things setup from the afternoon onwards.


 * Weekend of 22nd April 2015

Friday 21st April: 6pm Introductions, drinks, planning and ideas session Saturday 22nd April 10am Hackathon Start, wth other sessions (in an adhoc manner) throughout the day

Other things to do in Amsterdam around the same time: iPod Party (at Mac Expo) Mac Expo Amsterdam April 26th – 28th Amsterdam Blogonomics Conference April 27th 1-6pm Queen’s Day (April 29)

Who’s talking about the CocoaDevHouse Amsterdam?

  • BlakeBurris on CocoaRadio
  • EuroMacPodcast?, starting at the 9 minute mark on episode #1:
  • Attention Please
  • devdev2040
  • Stompy
  • Alper


The event will be hosted by our generous venue donours: Mediamatic and who are hosting a Beer and Breakout session on Friday evening.

  • CocoaDevHouseAmsterdam hackathon: Mediamatic, “Le Mepris” exhibition**

The CocoaDevHouse hackathon event will take place in the fabulous “Le Mepris’ and exhibition designed to resemble an airport lounge. Willem Welthoven of Mediamatic has also very kindly offered us the use of a reinstated Food Facility and GarageBox? Bar for the duration of the event. So that’s a hackathon, in an airport lounge, in an art exhibition!

  • Breakout and Beer (a breakout / social session with a beer)**

It’s going to be in Fleck’s headquarters. It’s going to be Friday night at a suitable point, and more importantly it’s going to be at Fleck! I’m told the beta isn’t quite ready for a sneak preview but you never know!

  • Location**

Both venues are in the same building; the famous PostCS? tower also home to the Stedelijk Museum (of Modern Art) and Club11! Just turn up and come to the Mediamatic space on the ground floor.

Oosterdokskade 5 1011 AD Amsterdam

On Plazes: Mediamatic: Le Mepris Exhibition: Food Facility: Garage Box Bar: Club/Bar/Restaurant 11:

Also pease add youself to the Wiki (edit this page) and also to the Upcoming event if you’re coming).

Flickr group for CocoaDevHouse is a good place to join and there are pictures from CocoaDevHouseDallas there.


CocoaDevHouse is a meetup where we hack away at cocoa! It’s a chance for Cocoa Developers, WebObjects? Developers, Mac Geeks, UX designers, and web service developers to meet up and make stuff. Amongst other things, there is always one of the CocoaDevHouse projects to hack away on, read more in CocoaAppIdeas?.

It’s an Amsterdam ‘chapter’ of CocoaDevHouse, hoping to attract Cocoa and Mac geeks from Europe and the Netherlands to Amsterdam for a weekend Hackathon and Show and Tell event.CocoaDevHouseAmsterdam is a hackathon for Cocoa Developers. A lot of people who are not necessarily Cocoa Developers are very interested, so we will also have adhoc sessions and discussions on anything related going on at the same time. These may include a session on WebObjects?,(Paul has volunteered) product show and tells (ask Boris about, or generally just meeting new people and hanging out in the Oosterdokskade!

For any devhouse/hackaton/unconference novices who want more info on the format, and history, I have blogged about this on my blog here:


  • -Could do with a little help and advice from the seasoned DevHouse? / Barcamp crew as to how much *sponsorship* is required to make sure everyone stays fed and watered!- Andy Smith has made a fabulous “How To DevHouse?”! We shall read and learn.


Cocoa Hackerati, Webservice developers, Wocoders, Designers, geeks and supergeeks!
