It's the time of the year again, namely it is December 2013, and so we shall now refresh our Community Promotion Ads for the new year.

What are Community Promotion Ads?

Community Promotion Ads are community-vetted advertisements that will show up on the main site, in the right sidebar. The purpose of this question is the vetting process. Images of the advertisements are provided, and community voting will enable the advertisements to be shown.

Why do we have Community Promotion Ads?

This is a method for the community to control what gets promoted to visitors on the site. For example, you might promote the following things:

  • interesting unix and linux related open source apps
  • the site's twitter account
  • script packs or power tools
  • cool events or conferences
  • anything else your community would genuinely be interested in

The goal is for future visitors to find out about the stuff your community deems important. This also serves as a way to promote information and resources that are relevant to your own community's interests, both for those already in the community and those yet to join.

Why do we reset the ads every year?

Some services will maintain usefulness over the years, while other things will wane to allow for new faces to show up. Resetting the ads every year helps accommodate this, and allows old ads that have served their purpose to be cycled out for fresher ads for newer things. This helps keep the material in the ads relevant to not just the subject matter of the community, but to the current status of the community. We reset the ads once a year, every December.

The community promotion ads have no restrictions against reposting an ad from a previous cycle. If a particular service or ad is very valuable to the community and will continue to be so, it is a good idea to repost it. It may be helpful to give it a new face in the process, so as to prevent the imagery of the ad from getting stale after a year of exposure.

How does it work?

The answers you post to this question must conform to the following rules, or they will be ignored.

  1. All answers should be in the exact form of:

    [![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 discuss something, do it in the comments.

  2. The question must always be tagged with the magic tag. In addition to enabling the functionality of the advertisements, this tag also pre-fills the answer form with the above required form.

Image requirements

  • The image that you create must be 220 x 250 pixels
  • Must be hosted through our standard image uploader (imgur)
  • Must be GIF or PNG
  • No animated GIFs
  • Absolute limit on file size of 150 KB

Score Threshold

There is a minimum score threshold an answer must meet (currently 6) before it will be shown on the main site.

You can check out the ads that have met the threshold with basic click stats here.

    Looks like dmr's shirt has some aliasing going on. Maybe this one could be replaced with a version that's been properly resized if it gets used? – WhiteHotLoveTiger Dec 10 '13 at 8:13
  • Here's another version with the same cropping. It's slightly dimmer, but I think the shirt looks better in this one: i.stack.imgur.com/wipgc.png – WhiteHotLoveTiger Dec 10 '13 at 9:49

    @WhiteHotLoveTiger Sorry about that. The image is fixed now (old vs. new). – ctype.h Dec 12 '13 at 4:58

Zsh: the last word in Unix shells

  • I see what you did there :D – Joseph R. Jan 15 '14 at 12:27

    @NewWorld Try this: grep -oP '\w+' /etc/shells | tail -1 – Joseph R. May 30 '14 at 13:04

    @NewWorld, yes, that's inspired from ZFS: the last word in filesystems. The image itself is stolen from zshwiki.org – Stéphane Chazelas May 30 '14 at 13:24

    It's the first time in 15 years of using perl that I come across (or notice I suppose) this logo. According to Wikipedia that's referring to pearl onions. Not so good an image given that it only works in english (German as well?), and even then, I don't see the point really. Possible confusion with TOR as well. – Stéphane Chazelas Jan 10 '14 at 22:13
  • 7
    @StephaneChazelas This happens to be the logo used by The Perl Foundation. Also, Larry Wall's Perl talks are called "State of the Onion". The Camel was popularized by the O'Reilly books. I put this image instead of the Camel intentionally hoping its lack of widespread recognition will prompt people to click through (hey, it caught your attention, didn't it?) :) I do agree on the potential confusion with TOR, though. – Joseph R. Jan 10 '14 at 22:51
  • 2
    @StephaneChazelas The pun does seem to work better in German, where a pearl onion is known as a Perlzwiebel :) – Joseph R. Jan 10 '14 at 22:54
  • @StephaneChazelas : I think this is a pretty common association -- perldoc has been using it for years too...although that web interface is really the work of a particular individual who may or may not be associated with the Foundation. Be happy it's not Duke... – goldilocks Jan 24 '14 at 19:38
  • I though it was TOR O_O – Kiwy Feb 14 '14 at 14:24

Haiku OS

  • 1
    Interesting. Does it offer its own implementation of POSIX utilities or does it rely on an existing one? – Joseph R. Jan 6 '14 at 14:07
  • 4
    @JosephR. no idea, I only know about it from an XKCD comic but it sounds cool and is open and *nix(ish) so we may as well promote it :). – terdon Mod Jan 6 '14 at 14:32
  • Hahahahaha. Great comic!! If only. In all such conversations I make a conscious effort to conceal the fact that I'm running *nix because you know they'll directly jump to blaming the problem on that. – Joseph R. Jan 6 '14 at 15:09

    @JosephR. I've found a trick, when I call my ISP tech support, I ask them things like "Do you know what ssh, telnet, ftp or ping are? No. OK, please let me speak to someone who does". That tends to speed things up wonderfully until I am talking to someone who knows more than I do and can actually help. – terdon Mod Jan 6 '14 at 15:12
  • Nice. Kind of a reverse Shibboleth, if you will :D – Joseph R. Jan 6 '14 at 15:13
  • @terdon does that actually work? if that wasn't a joke, you are my hero. – strugee Jan 20 '14 at 18:00
  • @strugee often it does, yes. It kinda freaks them out and they pass you on to the next poor schmuck down the line until you hit an actual engineer who can help. – terdon Mod Jan 20 '14 at 18:02
  • Definitly not a product with future, no offence for developers but an OS that start supporting 32bits only without relying on existing basis is lead to stay a very marginal product used only by there developers. that's only my personnal opinion but starting an OS now with the whole diversity and complexity of hardware (compare to the 90's) is a nice but fullish dream. (see reactOS... react what ?) – Kiwy Feb 11 '14 at 13:46
  • 3
    @Kiwy sorry but you completely misunderstood what this is. 1) Haiku is a continuation of BeOS which started in 1991 (though they have not kept much code) 2) it has not yet reached a stable release and they're working on 64 bit. Starting small makes sense. Anything that brings something like BeOS back into the game has my vote. – terdon Mod Mar 9 '14 at 1:54

  • There's server-side magic that detects the referrer and serve the proper image and it's updated in "semi-real-time". See the original for more information, specifically this comment – Braiam Apr 7 '14 at 3:38
  • This violates 2 of the requirements. 1) "The image that you create must be 220 x 250 pixels". 2) "Must be hosted through our standard image uploader" – phemmer Apr 7 '14 at 3:44
  • @Patrick check Apple's and Ask Ubuntu advertisement. It does work – Braiam Apr 7 '14 at 3:51
  • So 'the rules are more what you'd call "guidelines" than actual rules'? – phemmer Apr 7 '14 at 3:55
  • @Patrick obviously this add has been for a long while in SE and the SE team hasn't said anything against it. – Braiam Apr 7 '14 at 4:01
  • The fact that it's hosted by S.E. as a "dynamic ad" -- stack-exchange-dynamic-ads.herokuapp.com/bounty.png -- implies it's either created or endorsed by them, I think. Someone at least pulled some strings or plead the case to make this happen. +1 !!! – goldilocks Apr 7 '14 at 12:21
  • 2
    @TAFKA'goldilocks' Actually, the ad is neither created nor explicitly endorsed by Stack Exchange. The URL is as such because that app name was available on Heroku, so Jason and I picked it. However, by now I'd say that the ad has SE's implicit approval as it's existed for over 2 years on Ask Different without them removing it or objecting to it. – Kyle Cronin Apr 16 '14 at 14:39

  • There is another a Linux Mint ad option that I think is prettier. Since it's specific to the LMDE edition, maybe this could be revised with something prettier for the main edition. Maybe based on artwork from 17? – Caleb Jun 11 '14 at 7:20

Pipelight allows you to use Windows only plugins in Linux browsers. It supports Silverlight, Unity Webplayer, Shockwave, Flash and more.

    I'm aware this will probably get downvoted here, but in my opinion it's the best solution if you have to deal with this stuff (well, better than using a browser in Wine or even using a VM). Please tell me if you think this ad could be improved, or download the source file: pwnicorn.tk/public/AU-Pipelight_xcf – Donarsson Mar 5 '14 at 22:09
