Open Source Advertising - Sidebar - 1H 2011

Here is your chance to create a Free Vote-Based Advertisement for an Open Source Project. Create a graphical ad for an open source programming project and post it as an answer to this question (in the right format), and it will feed live remnant ads on stackoverflow.com.

Ad Requirements

It must be an advertisement soliciting the participation and contribution of programmers writing actual source code. This is not intended as a general purpose ad for consumer products which just happen to be open source. It's for finding programmers who will help contribute code or other programmery things (documentation, code review, bugfixes, etc).

In order to work, the answers you post to this question must conform to the following rules.

Answer Template

[![Tagline to show on mouseover][1]][2]

  [1]: http://image-url
  [2]: http://clickthrough-url

Please do not add anything else to the body of the post. If you want to add any commentary, keep it in the comments.

Image requirements

  • The image that you create must be 220px by 220px
  • Can be hosted anywhere (tinypic, twitpic, your blog); we will mirror the image locally when we serve it.
  • Must be GIF or PNG
  • No animated GIFs
  • Absolute limit on filesize of ~150kb

The output, which ultimately will be served in an ad slot on Stack Overflow, can be previewed by clicking through to this URL:


There is a minimum score threshold an answer must meet (currently 6) before it will be served up by that URL and shown on Stack Overflow. You can see all the ads that currently make the threshold and meet our criteria on this page:


  • lol this question is already serving it's purpose. I'm curious about some of these projects I've never heard of before. – Doug T. Dec 5 '09 at 2:58
  • 3
    Will there be similar ones for the rest of the trilogy? Apps like pidgin could go to superuser and serverfault could get admin-oriented tools. – alanc Dec 5 '09 at 3:49
  • Should the ads indicate what kind of help the project is looking for? Are ads for open-source programmer tools acceptable? – Don Kirkby Dec 19 '09 at 7:25
  • 3
    @Jeff. I think this is a wonderful scheme you have going here. The only thing is I find it frustrating to see the add and not have a explanation of what it is. I know you said this can be done via comments but it doesn't seem to be happening so far. – Tim Murphy Dec 19 '09 at 11:25
  • 7
    Can other sites run these ads? IE are they contributed beyond just stackoverflow? – dlamblin Dec 19 '09 at 15:40
  • +1 for @dlamblin You could easily provide listings for other websites. – chakrit Dec 19 '09 at 20:55
  • Quibble on the format, but is it just Safari, Chrome and Firefox or does the "Tagline to show on mouseover" not show? – dlamblin Dec 21 '09 at 6:59

    Is it just me, or are the majority of the ads here not an ad for programmers, but for a product? – Powerlord Dec 21 '09 at 19:31
  • 3
    R. Bemrose, one assumes that programmers would want to try the product then contribute to it. So the rule is, the project must allow outside code contributions and somewhat actively solicit outside code contributions. – Jeff Atwood Dec 21 '09 at 20:20
  • @dlamblin: If you open up a new question called something like "running open source ads on 3rd party websites" we can start to flesh out how that would work. The initial problem is that the ad size on StackOverflow (220x250) is not an IAB standard and few websites (if any) will be able to use this size. But start the topic and let's try to figure out how to make it work. – Portman Dec 22 '09 at 21:13

    It would be interesting to see a report comparing the effectiveness of the adds (how many people clicked on them) vs. how high they were voted. Are Meta user's effective add pickers or are they just oppinionated? – Anonymous Jan 1 '10 at 19:24
  • The ad I appreciated the most was the JQuerySharp. I think there's only one thing more motivating to a geek than to be addressed as "My Lord." – Carl Smotricz Jan 8 '10 at 15:02
  • 1
    Just wondering: has the minimum score threshold been changed? Because there are two ads with 5 up votes that seem to meet the other criteria (meta.stackexchange.com/questions/31913/… and meta.stackexchange.com/questions/31913/…) but are not on rads.stackoverflow.com/ossads/all - or is some manual approval involved and it just takes some time? – Fabian Steeg Feb 12 '10 at 18:03
  • 2
    Rather than adds for Open Source Projects, I'd really appreciate a list of projects that need help with a quick summary of what needs to be done in each one--what they are hoping to accomplish with this additional manpower. If there is such a site, advertise that! – Bill K Feb 18 '10 at 23:33
  • 6
    Are dupes with different ad images acceptable? Doesn't exactly seem fair to load up multiple ads for a single project and drown out others. – random Feb 21 '10 at 4:28

Perl (and Python!) Template Toolkit

  • Cool. What about it? – macek May 5 '10 at 20:20
  • 1
    @macek: What do you want to know? Template Toolkit it arguably one of the most used opensource templating systems out there and used by some big companies. Its a grandaddy of the template systems and as influenced many others of the years. TT2 is currently available in Perl & Python. And there is a complete TT3 rewrite which could always do with a hand or two: github.com/abw/Template-TT3 – draegtun May 6 '10 at 10:24
  • 1
    Dang True! For what it does TT is one of the open source greats. TT docs should be required reading for anyone who works with or builds any kind of string templating system. – dreftymac May 20 '10 at 16:04
  • I was giving you a hard time because it doesn't solicit programmer contribution. You're advertising a product. – macek Jun 9 '10 at 15:00
  • @macek: I didn't realise u were giving me a hard time :) TT is an opensource project like others on here and like them programmer contribution is their life blood. – draegtun Jun 19 '10 at 12:34

  • As said in another post, "Liero is a game that is totally worth checking out. That said, this ad doesn't do it a lot of justice." (macek). Just a digging worm cannot call more programmers and players. Put 1 more worm and more 2 players with another skin, more weapons shotting and some explosion on a better level. The text would be in a more aggressive font; the text could be and like that: "OpenLieroX: a game with a lot of explosions for worms and brains". You can add piece of code as watermark in some picture part - like little lua commands. – kokbira Jul 17 '10 at 2:49

    Respectfully, you may wish to re-consider your approach if you are trying to make a more 'favorable' impression. How does this ad help to counteract the message of the previous ad? If anything, it seems to perfectly reinforce the point. Even if people can decipher your point about the White House, U.S. Government agencies are notorious for deploying sloppy, bloated, inelegant code that no one wants to acknowledge, let alone maintain.
