Creating Share Buttons for Twitter, Facebook, and Linkedin using Django Templatetags

Andrew Konkol — Mon, 22 Aug 2011 19:50:17 +0000

It’s easy to copy and paste urls to share links, but its easier to just click on a button to do it. The way I decided to do it was to write a custom django templatetag. The template tag exists in myproject/myapp/templatetags/sharebuttons.py.

You can use the pre-built template here

Usage in a template:

{% load sharebuttons %}

{% for p in posts %}
   {% sharebutton p "twitter" %}
   {% sharebutton p "facebook" %}
   {% sharebutton p "linkedin" %}
{% endfor %}

Jquery UI Autocomplete 1.8 with Django Views

Andrew Konkol — Wed, 03 Aug 2011 13:52:13 +0000

I have a model named “Show” and it has a ForeignKey to a model named “Venue.” When users add a “Show” I wanted an autocomplete(d) field venue.

This solution uses:

jquery-1.6.1.min.js
jquery-ui.min.js

models.py

class Venue(models.Model):
        name = models.CharField(max_length=255, blank=False, null=False, help_text="Name of the venue")

class Show(models.Model):
        date = models.DateTimeField(blank=False, null=False)
        venue = models.ForeignKey(Venue)
        headliner = models.ForeignKey(Artist, related_name="Headliner")

urls.py

(r'venue_lookup/$','projname.appname.views.venue_lookup'),

views.py

def venue_lookup(request):
   venues = Venue.objects.filter(name__istartswith=request.REQUEST['term'])
   results = []
   for venue in venues:
      venue_dict = {'id':venue.id, 'label':venue.name, 'value':venue.name}
      results.append(venue_dict)
   return HttpResponse(simplejson.dumps(results),mimetype='application/json')

Template:









        Venue

“Live, Dynamic” text generation with jQuery using replace()

Andrew Konkol — Mon, 23 May 2011 20:38:12 +0000

When you manage a bunch of similar devices, it’s nice to generate consistent configurations quickly. I built a config file generator last week which you embed the variables in plain text such as “$hostname.” Then a web form is generated based off those embedded variables and a find and replace is done on the config text. The app has been up and running for a about a week and has made our deployment of new gear at sites a snap.

I wanted to add some candy to it. So now what happens is when you enter values into form fields the configuration file is generated in “real time” in front of your own two eyeballs.

Powerline Fishing

Andrew Konkol — Fri, 19 Jun 2009 04:28:57 +0000

I’ve been fishing on Chicago’s lakefront since I was a very young child. There is a certain culture that arises from people that like to fish but don’t have boats. I never picked up on this culture until I lurked several chicago fishing messageboards. Like any hobby, hobbyists are nerds which can’t wait to tell you about something they built… and help you along in your own projects.

I’ve always heard the rumor or urban legend about powerlining rigs. Powerlining is essentially launching a high test fishing line out with an anchor and several baited hooks. Pitching a line out with several other smaller lines allows you to achieve distances (and in turn depths) that would be hard to achieve using the traditional rod and reel.

There are three main ways to pitch this monster line out into the water:

Throwing the anchor/weight by hand
Using a water balloon sling shot
Using the pressure of a CO2 tank (think potato gun)

Guess which one I’m interested in…. you guessed it… CO2 tank.

After perusing several messaging boards I’ve come up with the following bill of materials:

CO2 Fire extinguisher
5ft of 1″ pipe
some sort of pipe adapter (I’ll figure that out once at home depot)
12 oz 1″ x 2.5″ weight
70′ of rubber band/cord
A couple hundred yards of 10-12 lb test
Reel
two large swivels
10 smaller swivels
hooks
beads

Then my additonail ideas:

Door stopper spring
Dowel rod
Bell
Screweyes

The plan I’m working on… still need to add snelled hooks.

10 Gallon Cooler Mash Tun

Andrew Konkol — Sun, 03 May 2009 20:15:30 +0000

I brewed my first beer solo a couple of weeks ago and it tastes pretty decent! After doing some research I came to the conclusion that I had to go all-grain. First of all it’s supposed to taste better, second it gives me an excuse to build something. There are many plans on the web on how to make a cooler mash tun… and mine isn’t any different.

I’ve been using AVG on and off for a while now and I hate that pesky email signature they add to scanned emails. Well, I found out how to get rid of that.

The Holidays were pretty good to me…

Andrew Konkol — Mon, 05 Jan 2009 00:24:32 +0000

I got a bunch of cool stuff this year. My favorite is probably the GPS my fiance got me.. I get lost very easily. My expected favorite is the Drobo, my un-expected favorite is my caliper. 2008 was interesting..

Got a job at a media giant, that is somewhat sinking.
Got enganged
Picked up ruby and python (python is winning)
Built a CCNA lab
Got into microprocessors
Started to brew beer
Got more networking experience than ever before
xbox with netflix changed my life.

Best Tech Things of the Year / Found Out About this Year (to me.. in all seriousness)

Adafruit Industries ( actually useful kits)
Ponoko ( next best thing to owning a laser cutter)
SlugPower (seriously my favorite hack of the year, it’s not hard to control a relay over serial.. but the integration and thought is awesome)
Netgate (for the diy router/firewall maker)
Drobo ( I’m allowed to say that.. I’ve built almost a dozen different NAS’s)

Here’s some stuff I got:
