Building a treehouse

About a year ago we decided to build a treehouse into our walnut.

So I kept my eyes open to see how others build their tree-houses. And finally on our last trip I found a way to get it done. I had a look at how the platforms on a high-rope-garden had been build and it seemed rather easy. Take two wooden beams, drill a hole on each side, connect them with threaded rods and tighten. The beams will then clamp around the trees trunk and hold tight. Add that setup right on top of the first one rotated by 90 degrees with longer beams so they can be used to add planks on top. Might sound complicated but it’s rather easy.

At least it’s easy when you have a straight, upright tree. At least that’s what I had to find out the hard way. Our walnut is everything but straight and upright. I struggled a while trying to get the beams halfway parallel to the ground. Until I finally gave up and had to think up something else. The idea of clamping the platform for the treehouse onto the tree was great, but it didn’t work out to use that technique to support the platform from below.

So after a week of thinking it through I decided to try a different way. When I can’t support the platform from below, I might be more lucky suspending it!

So I looked for a rather upright part of the tree and clamped two beams onto that and added two more above rotated. And on top of that I took 4 stainless steel-ropes around the tree.

Then I built the supporting base at the foot of the tree from 8x12cm wooden beams with 3,2 m length each. The 2 main beams got each 2 holes drilled right through through which I took the steel-ropes. The I hauled the thing up using some supporting ropes to get it to the final height and secured everything with the steel ropes. Base support hanging!

And from there on it was just a matter of „just do it“. Adding the remaining beams and putting the flooring onto those with cutouts for the tree was then the fun thing to do.

The next thing will be the walls and a partial roof to make it possible to enjoy some rain out there. But that might then become another story.

Development against the joind.in-API

Reminder to my future self:

Obtaining an authentication token from the joind.in-API using the vagrant-box via curl:

curl --data "{\"grant_type":"password","username":"<username>","password":"<password>","client_id":"web2","client_secret":"web2secret"}" -H "Content-Type: application/json" -H "Accept: application/json" http://api.dev.joind.in:8080/v2.1/token

And then using that token via curl:

curl -H "Authorization: oauth <token>" -H "Content-Type: application/json" -H "Accept: application/json" --data "{}" http://api.dev.joind.in:8080/v2.1/<endpoint>

wordpress and markup

Markup is a great way to write text. And I wanted to be able to write my blog-posts in markup also. And I also wanted to be able to write code-snippets in markup.

It proved rather easy to integrate Jetbags markup-engine without the overhead of installing the complete jetbag-suite.

Just install and activate the jb_markup plugin. For code-highlighting I use the SyntaxHighlighter Evolved-plugin.

Caveat: The JB_Markup-plugin converts the markup to HTML with wordpress-tags on saving the post. That’s fine, as long as you do not turn on Syntax-Highlighting after saving the post. On saving the post JB_Markup checks whether the Syntax-Highlighter is activated and depending on that convertts code-blocks either to a simple ‚pre‘-tag or uses the \-syntax which enables the Syntax-Highlighter. So when you enable the SyntaxHighlighter after you wrote a post, you’ll have to resave the post!

Displaying Date-Ranges

Recently a new issue popped up on the joind.in issue-tracker which called for nicer date-ranges. As I did something like that a few weeks prior I grabbed the issue and starded working.

The output is a small library that enables you to display a date-range like 12. – 13. March 2015 instead of 12. March 2015 – 13. March 2015.

Simple thing.

It also displays March 12th – March 13th 2015 if you want to.

Not that easy any more.

I won’t bother you with the details on how it’s done (it seemed more difficult than it actually was) as you can see that in the source-code if you are interested.

joind.in – a personal plea

Joind.in is a community driven project to give feedback to speakers at conferences and events.

And besides that it is a great ressource for all those that want to participate in the community. Not only as it’s an opensource project that everyone can help to make even better! But to provide feedback it also contains a list of almost every conference and event that is of any significance to the (PHP-)community.

And as the driving force underneath the hood of joind.in is a great API everyone interested can do a lot of cool things with the data no one has ever thought of.

To get the most out of joind.in (and therefore that API) some things should to be considered when creating or editing an event in joind.in. Some of these I’ll list here:
