# Community Promotion Ads - 2014

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. This is a link to the previous thread.

### 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:

• useful tools or resources for the mathematically inclined
• interesting articles or findings for the curious
• 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.

Is there a reason why this isn't linked to the OEIS main page? –  Arthur Fischer Dec 6 '13 at 12:15
@Arthur I'm not sure, but IMHO search result page better demonstrates its usefulness. –  Grigory M Dec 6 '13 at 12:20
What about linking the ad to a random page so each time one clicks on it, a new sequence will be displayed? –  Alexander Konovalov Dec 6 '13 at 16:44
Ah, one of the comments of the sequence that is currently linked to the ad actually says that its first 14 terms appear in the OEIS logo - then it seems to be a perfect candidate to be linked! –  Alexander Konovalov Dec 7 '13 at 1:19
This one’s so useful that I even donate a little to them each year. –  Brian M. Scott Dec 12 '13 at 21:12

Or because noone can draw beautiful curly braces like this with a mouse. –  Phira Feb 19 at 7:37

Perhaps it is time to update the number to 900k? –  Asaf Karagila Dec 7 '13 at 22:54
True. But by 2014 it ought to have that amount. This thread is for ads for 2014 (whether or not they appear now is a whole other thing)... Anyway, I think it is worth being prepared. :-) –  Asaf Karagila Dec 9 '13 at 8:50
@AsafKaragila: finally, it's time to update: I've just seen it reporting 900,267 e-prints. –  Alexander Konovalov Dec 18 '13 at 21:42
Huzzah! Next year: 1M. –  Asaf Karagila Dec 18 '13 at 21:43
I still had the GIMP .xcf file from last year's fix, so I went and updated it again. –  Ilmari Karonen Jan 26 at 0:17
Ps. Here's the .xcf file, in case someone else wants to update it for 1M. :) The font used is Aller. –  Ilmari Karonen Feb 7 at 21:16

@SamB: Interesting. They've changed their license recently it appears. Quoting from the Wikipedia link: while the source code is licensed under the terms of the GNU General Public License, the translation files, installers, and web services are licensed under non-GPL-compatible terms. Commercial use is prohibited without the purchase of a separate license. It has been noted by the maintainer of the software in Debian GNU/Linux that these terms, a change from earlier releases, prevent the resulting combined work from being considered free software and may be nondistributable. –  Assad Ebrahim Mar 22 at 0:22
@AssadEbrahim: Ah. After looking at the terms shown on the site, the idea of it being in Debian naturally didn't cross my mind... I wonder how hard it'd be to get a free fork caught up on the translations? –  SamB Mar 24 at 16:53

NOTE: you can customize MathJax with your own macros in Settings->Extensions->MathJax->Tex configuration. See docs.mathjax.org/en/latest/tex.html#defining-tex-macros. –  benweet Jan 18 at 12:35

Could the $3$ downvoters explain their act? –  user93957 Dec 21 '13 at 18:57
At least I can explain mine: free ads for commercial product. No way. –  Jean-Claude Arbaut Dec 24 '13 at 9:28
@arbautjc The pricing link is for upgrading one's account, the main features of writeLaTex are free. –  user93957 Dec 24 '13 at 12:47
Yes, like WolframAlpha and many others, the free stuff is here to push people to buy the commercial stuff. As I said, I won't upvote free ads to a commercial product. –  Jean-Claude Arbaut Dec 24 '13 at 12:52
@arbautjc Your reason isn't viable. Community promotion ads are for: \begin{align} \circ & \text{the site's twitter account }\\ \circ & \text{useful tools or resources for the mathematically inclined}\\ \circ & \text{interesting articles or findings for the curious}\\ \circ & \text{cool events or conferences}\\ \circ & \text{anything else your community would genuinely be interested in}\\ \end{align} Wolfram and writeLaTeX are perfectly compatible with that chart because of the second and last reasons. –  user93957 Dec 24 '13 at 12:59
It's not prescribed by MSE that ads are only for free sites. But it's my choice that I will downvote any ads for commercial ones. You asked for the reasons of downvoters, I gave you mine. –  Jean-Claude Arbaut Dec 24 '13 at 12:59
@arbautjc "the free stuff is here to push people to buy the commercial stuff." - not necessarily. –  user93957 Dec 24 '13 at 13:00
This discussion would never end. I perfectly accept, and understand, that we disagree. I'm not in the least trying to convince you. And on the other hand, there is no issue for you, since there are already more than enough upvotes for this one. –  Jean-Claude Arbaut Dec 24 '13 at 13:04

+1, but, please--nicer theme! It would be great to have a different theme. Someone with free time (like anyone has that) should write a similar script but with a theme more conducive to the MSE theme. –  anorton Dec 12 '13 at 2:09
Yeah: "There are currently less than $e^\pi$ active bounties, worth $\pi^{e^2}$" –  draks ... Dec 12 '13 at 12:28
@IlmariKaronen The image works perfectly on Apple.SE even if it size is greater than 220x250 (it get displayed at the correct size through) and if it isn't hosted by imgur. –  user93957 Dec 14 '13 at 12:25
Somewhat-significant bug: if you're not logged in, this redirects to the plain front page. –  Nick T Jan 13 at 21:21

lol... I never thought of advertising Wolfram since it is too popular. –  user93957 Dec 12 '13 at 19:02

@arbautjc I think wolframalpha isn't mainly a CAS, but something special, because of you don't need to know a bit of syntax to use it while for most CAS you need to know the correct syntax. Furthermore the basic functions of wolframalpha are free –  Dominic Michaelis Dec 24 '13 at 15:30

I’m not terribly keen on the idea of recommending this site: I find the house style rather opaque, verging on obfuscatory. –  Brian M. Scott Dec 12 '13 at 21:09

-
I upvoted this, but IMO, the biggest weakness of this ad has always been that it says nothing about what Khan Academy is. If you don't already know what it's about, there's nothing in this ad to tell you why you should click it (or upvote it, for that matter). –  Ilmari Karonen Dec 28 '13 at 22:32
Yes, this ad is completely uninformative ... –  SamB Jan 10 at 20:08

Made in Mathematica for a lack of proper tools (not proudly). Please feel free to improve the post and especially the graphic (or down/up vote). The tool itself is very useful (at least to me). I added their standard tag to the found original image source and ensured dimension conformance. –  J. W. Perry Dec 22 '13 at 3:54
Really valuable for its ability to create interactive Cartesian demos that can be shared over the Internet. –  hardmath Feb 1 at 23:35

@ErelSegalHalevi I'd be very glad if you could work/contribute to the site as well! –  Jernej Apr 28 at 8:54

I still dislike "funnest", but perhaps it only bothers me. –  Austin Mohr May 7 at 22:59

Free ads for commercial product. I downvote. –  Jean-Claude Arbaut Dec 24 '13 at 9:27

I like the idea of promoting Academia.SE. But 3 differently styled texts (white on black, pink on white, black on white) looks... somewhat unprofessional, maybe. Oh, and 19 words (3 words «academia» included) seems to be too long for an ad. –  Grigory M Dec 6 '13 at 18:42
I'd prefer version without that black frame (with its text) and without pink font, maybe? –  Grigory M Dec 6 '13 at 18:43
As I commented last year, I still think "Rocking your world" is in poor taste. –  Austin Mohr Dec 16 '13 at 3:12

Rather minimalistic, if anyone has an idea to improve... –  Jean-Claude Arbaut Dec 21 '13 at 10:02

I dislike this advert for two reasons. Firstly, it is implying that I, as a user of this site, use something I do not use. Secondly, it tells people that it is "okay not to know your functions!". This is (arguably) true when you get a certain level, but most students here will not be at that level yet... Also, being allowed to not know your functions is then extended (in the students minds) to "not knowing your derivatives" and so on until we get to "not knowing your definitions". –  user1729 Dec 17 '13 at 11:01
(I should say thought: I don't mind the site itself being advertised, just not with this advert.) –  user1729 Dec 17 '13 at 11:35
Upper half with text over formulas looks somewhat... messy, IMHO. –  Grigory M Dec 21 '13 at 18:14
(And maybe this one also has just too many words...) –  Grigory M Dec 21 '13 at 18:16
"Power up your memory with Digital Library of Mathematical Functions!" or brain implant jokes are better. –  FrenzY DT. Dec 26 '13 at 14:46

what is bad with the Twitter account? –  dwarandae Jan 23 at 22:59
@dwarandae That's the wrong question. The correct question is: What is good about promoting it? There's much more interesting stuff to promote here. –  tohecz Feb 12 at 12:51

I downvoted for two reasons. Firstly, I have no idea who Derek Owens is and what he does. Secondly, how do I know that you are not Derek Owens and are just trying to plug yourself? (The latter issue would be resolved by you just saying "Disclaimer: this ain't me".) –  user1729 Dec 18 '13 at 9:48
@user1729 1) If you saw what's in the background of the image you'll then know. 2) I'm not Derek Owens just as I'm not Sal Khan (I posted an add referencing Khan Academy). –  user93957 Dec 18 '13 at 12:29
Khan's academy is well-known and so advertising it would not be odd, but I (as a small sample population of members of this site) have never heard of Derek Owens. I have clicked on the link so I know that he runs some sort of youtube channel about maths. But then you haven't given me a reason to upvote it. So do lots of people. What stands out about it? (Also, as to your reply of "If you saw what's in the background of the image you'll then know", the advert tells me that he does maths. But then so do most of the adverts we are discussing here.) –  user1729 Dec 18 '13 at 13:36
Yes, you are right, I didn't see the quality of his videos because by this point I wasn't voting on the product, as it were, but the advert. It tells me that there is some guy called Derek Owens who does maths. Again, this is where Kahn Academy comes out on top. I have never watched a Kahn Academy video, but I know that if I did it would be teaching me something. It is an academy. Derek Owens might be doing magical maths card tricks for all I know... My point is that you need to change the advert to actually say something. "Derek Owens: Maths videos!"..."The Derek Owen's school of maths!"... –  user1729 Dec 19 '13 at 9:23
Okay I will try to improve the ad @user1729 –  user93957 Dec 19 '13 at 12:28
