Notes JSConf.EU 2011 - Summary of the 1st Day

Alright, …, day 1 of the JSConf.EU is done and while other are trying to minimize the results of the after show party I’ll try to summerize the (visited) talks:

Art

Not a talk at all but a very nice detail was the artist Anna Lena Schiller. The Fräulein (see the website) created an artwork for each of the talks in the downstairs area.

Plask

The first talk was by Dean McNamee about the multimedia programming environment Plask. It might be my inability to completely understand native american speaker or the complexity of the topic, but I don’t exactly got the point :D As far as I’ve understood, Plask is an environment which can be used in order to easily analyze multimedia and trigger stuff according to the resulting data. Dean presented some showcases including a visualization of music (via a nicely animated wave stream) and an experiment by a car manifacturer, who filled the inner of the car with gas and placed some LEDs into it. The LEDs were then colored according to the bass of the music. Check out the website for the video.

One thing I’ve noticed, is, that Anna Lena had a type :D It’s “Plask” not “Plusk” ;)

Notes [sdepold] Sharing Rubymine preferences via Dropbox

devanda:

Motivation

If you are using Rubymine (like ~50% of the DaWanda devs is), you might have got the idea of sharing your preferences with multiple computers. Because most of us are coding on Apple hardware, this description is for MacOSX, but will work similarly on linux as well.

The naive way

When thinking about sharing stuff on multiple devices, you will stumble across Dropbox. The first and obvious way is moving your preferences folder into it and symlinking it into the origin place:

mv ~/Library/Preferences/RubyMine31 ~/Dropbox/System/Preferences/
ln -s ~/Dropbox/System/Preferences/RubyMine31 ~/Library/Preferences/RubyMine31

When starting RubyMine for the next time, it will complain about a missing preferences folder and bootup some strange environment in which you can work almost normally but have no shortcuts etc. The very next thing I tried was symlink without the “-s” flag. This will fail due to MacOSX’ missing support of hardlinks for directories.

Solution

After googling for a while, I found this discussion on StackOverflow. It explains how to compile a binary for creating directory symlinks. So copy the following snippet and paste it into your favorite place for binaries and shell scripts (because I like sharing custom binaries via Dropbox it is ~/Dropbox/System/Bin/hlink.c for me).

#include <unistd.h>
#include <stdio.h>

int main(int argc, char* argv[]) {
  if (argc != 3) {
    fprintf(stderr,”Use: hlink <src_dir> <target_dir>\n”);
    return 1;
  }
  int ret = link(argv[1],argv[2]);
  if (ret != 0)
    perror(“link”);
return ret;
}

Afterwards “cd” into that specific folder and do this:

cd ~/Dropbox/System/Bin
gcc hlink.c -o hlink

And finally:

mv ~/Library/Preferences/RubyMine31 ~/Dropbox/System/Preferences/
./hlink ~/Dropbox/System/Preferences/RubyMine31 ~/Library/Preferences/RubyMine31

When running RubyMine for the next time, everything should be just as before!

Have fun,
sdepold

niskavaara asked: I'm looking at "Connecting Up MongoDB" at this page http://dailyjs.com/2010/11/08/node-tutorial-2/

I've looked thru the examples at sequelizejs.com but couldn't find a similar example.

Would it be possible for you to add an example of how to define the data model and relations in models.js for use in Express?

Thank you!

hey there, thanks tumblr i just got your message now :D I also have no clue when you asked me. If I understand right, you want to define your models in an extra file?

Text Working with ssh keys

This is mostly a reminder for myself. But maybe you are also interested in this :)

So this is the way you can access a server via ssh without getting asked about passwords:

1. Create a SSH key. You might want to take a look at this to get one.

2. Copy the result of the following command: cat .ssh/id_rsa.pub

3. Connect to the server: ssh user@server.tld + Enter password

4. Create the .ssh folder if not yet done: mkdir ~/.ssh

5. pico ~/.ssh/authorized_keys => Paste the clipboard.

6. exit

7. ssh user@server.tld => You should now be connected without entering a password!
