I'm looking to get my hands on an API (hopefully one that's platform agnostic) that allows me to retrieve real time (or as close to it) equity prices / volume (hopefully).
I'm not a professional trader and can't afford anything really expensive (although I'm willing to pay a fair bit a month for such a service). I'm seeking to monitor about 500 equities (SP500) to start.
Does anybody have any suggestion? I don't want to use something like Google, because I would in effect be stealing a lot of bandwidth and could be blocked for abusing the service.
Google is a relatively shockingly developer friendly company. I have had some interactions with them about volumes of API use. You can hit them quite a bit without getting blacklisted.
One project that I am aware of being developed by Collaborative Software Initiative: FeedHandler: http://csinitiative.com/products/feedhandler/
I am not sure what the cost of the feed would be like. They would be able to track all of the stocks.

I have an idea for a new project that would require me to get the news feeds from many RSS news feeds. I am unable to find a free or affordable API that lets me do this. All I have found is NewsCred, which is significantly too expensive for me. It doesn't seem practical for me to manually input the feeds of 2000 different newspapers both from a time standpoint, and due to potential legal-related licensing issues.
What about Superfeedr? (I created it!). We provide an API that will do the fetching, parsing and and diffing of all the feeds you supply, in realtime.
The main difference with NewsCred is that you are the one picking your sources and supplying them to us. We accept any kind of RSS/Atom feed and already power services like IFTTT for example.

(I asked on programmers.stackexchange.com but my question got voted down into the negative, so I'm re-asking here.)
I'd like to use a map API for a private intranet web site I'm developing. The Google Maps API is free as long as the web site that uses it is also free. For private intranet web sites, the Google Maps API costs $10,000 US per year (or more) for a business/enterprise license which makes it too expensive for a small 1-guy shop like myself.
So now I'm looking for other options. Are there any usable HTTP map APIs that are free or lower/reasonable cost?
You might wanna check this and this too because what you think about the rules about Google Map is not entirely true. To answer your question, most other providers carry similar license agreement; plus, the solution is not hard to be found hence the voting down (I suppose, no offense).
Anyhow, try Googling OpenStreetMap, hope this helps you!
Google GeoCharts is not a street-by-street level maps and satelite pictures familiar to Google Maps users, but it worked great for what I needed. You can find it here: https://developers.google.com/chart/interactive/docs/gallery/geochart
(Actually, the entire Google Charts javascript library is quite amazing!)

a.) Are there any websites, tools, etc. that are platforms for testing stock trading applications?
b.) Are there any platforms apis etc that allow automated trading?
Any thoughts?
Also, i particularly like coding in python.
Quantopian is a great solution. It lets you upload and test your algorithms on large data sets, while keeping them private or sharing with the community.
RTS Realtime Systems is a well-known trading platform. It is written in Java, though.
When you are searching for testing tools, try to search for the term backtesting and algorithmic trading. I came up with this result: PyAlgoTrader

I'm trying to build a "fantasy team" site but I can't seem to find an API for the English Premier Leauge. Is there one for free or do I have to pay to get that information?
Thanks!
/Niklas
Edit
My idea was to charge $10 for entering a team and to have a payout structure like a tournament, with percentages of the main pot. Like 20% to the winner, 15% to the runner up etc...
Would that count as commercial use?
Do you know if Yahoo's API (YQL) can do this?
I used to use one from Score24, which was awesome.
It's not free though, I believe we paid about 50€ / league / month, but that was 2005.
But it's fast, really fast. There just a couple of seconds between a goal and the XML message they send. Really cool.
They also have the teams with all the players before each game and they give you goals, cards and everything you need.
Have a look!
Try http://www.footytube.com/openfooty/. It's got lots of data about football teams, players and matches, and it's free for non-commercial use.

I read this book:
Head First Object-Oriented Analysis and Design
Now i am looking forward to find a Software that make it easy to collect all my Ideas etc (specific Software for OOA).
At the moment i am using my Whiteboard to collect/design Ideas etc. Afterwards i am taking pictures of it and add text to our Wiki/Trac.
At school, we're using Objecteering, which is easy to use, integrated to Eclipse, but not free.
IMO blank paper is a must, but not always the easier to share and to edit.
Install mediawiki (the stuff that powers wikipedia, don't settle for anything less you will need the full feature set eventually) and put all your ideas in there. This makes it easy to refine them and to improve then as time goes by.
