I searched through the documentation and examples but could not find a complete list of network types. I looked at the OSM API documentation as well. I know a few like "all", "drive", "bike", "walk" but is there a complete list somewhere?
See the documentation. There is a list of possible network_type arguments in the docstring of every graph_from_whatever function. For example:
network_type (string) – what type of street network to get if custom_filter is None. One of ‘walk’, ‘bike’, ‘drive’, ‘drive_service’, ‘all’, or ‘all_private’.

I'm trying to use version 2 of the Twitter API to achieve the goal described in the title. Here's what I have tried so far:
Listening to sample stream (1% of Twitter's stream): Almost all the returned Tweets don't have geo-info when following this approach. And it makes sense, since only 0.85% of all Tweets have geo-info.
Listening to a filtered stream with only one rule setup, namely the has:geo rule. But it's returning the following 2 errors:
"Reference to invalid operator 'has:geo'. Operator is not available in current product or product packaging. Please refer to complete available operator list at https://developer.twitter.com/en/docs/twitter-api/enterprise/rules-and-filtering/operators-by-product. (at position 5)".
"has/is/lang/sample cannot be used as a standalone operator (at position 1)".
Here's the rule I'm adding to the stream:
[
{
"value": "has:geo",
"tag": "contains geo-info",
},
]
I need help in solving both shown errors, or a suggestion describing a third different approach.
I see this question has been discussed on the Twitter Community forum: https://twittercommunity.com/t/how-to-listen-to-tweets-that-only-contains-geo-info-from-twitter-stream/162905/2
Short answer:
The has:geois one of several query operators that can not be used in a standalone fashion, and must be paired with keywords and other non-boolean operators.
The has:geo operator is only available in academic and paid packages.
I want to get minimal information of a Wikipedia page using MediaWiki API like DuckDuckGo. For example for Steve Carell: https://duckduckgo.com/?q=steve+carell&t=hp&ia=news&iax=about
How can I get this information with a Wikipedia url (eg https://en.wikipedia.org/wiki/Steve_Carell) in HTML format?
You can use the MediaWiki API for that. There's an extension, TextExtracts, which is exactly for that (and it is installed on Wikipedia).
In your case, e.g.:
https://en.wikipedia.org/w/api.php?action=query&prop=extracts&exsentences=1&titles=Steve%20Carell
will return something like:
<p class=\"mw-empty-elt\">\n</p>\n\n<p class=\"mw-empty-elt\">\n \n</p>\n<p><b>Steven John Carell</b> (<span></span>; born August 16, 1962) is an American actor, comedian, producer, writer and director.</p>
You can customize how many sentences (or characters) the API returns, as well, please consult the API documentation for that.
There's also the way to retrieve the short description, which is saved at Wikidata (and visible in the mobile view of Wikipedia). This call would be:
https://en.wikipedia.org/w/api.php?action=query&prop=pageprops&titles=Steve_Carell
This returns the following property in the pageprops of the page:
"wikibase-shortdesc": "American actor"
This may fit better depending on your use case.
You can even get both of the results with a single, combined, request:
https://en.wikipedia.org/w/api.php?action=query&prop=extracts|pageprops&exsentences=1&titles=Steve_Carell
I'm a beginner looking for some clarity on how to create configuration files for the DDS Recording Service in two areas.
If you are looking to record a set of specific topics from a domain how do you set up the topic group? Can you list the topics as individual <topic_expr> i.e.
<topic_group name="SomeTopics">
<topics>
<topic_expr>topic2</topic_expr>
<topic_expr>topic8</topic_expr>
</topics>
<field_expr>*</field_expr>
</topic_group>
When I tried something like this not all the listed topics would be recorded. Is there something I am overlooking?
Secondly, when you use -deserialize to you need to make any changes to the configuration file you used to record the database? As I sometimes get errors about how "rti dds failed to find" followed by something like X::Y::Z. Thanks.
The XSD schema for the configuration file does not expect you to use multiple <topic_expr> tags, but a single tag with a comma-separated list of Topic names. The RTI Recording Service User's Manual explains it as follows:
<topic_expr>POSIX fn expression</topic_expr>
Required.
A comma-separated list of POSIX expressions that specify the names of Topics to be included in the TopicGroup.
The syntax and semantics are the same as for Partition matching.
Default: Null
Note: Keep in mind that spaces are valid first characters in topic names, thus they can affect the matching process. For example, this will match both Triangle and Square topics (notice there is no space before Square):
<topic_expr>Triangle,Square</topic_expr>
However the following will only match Triangle topics (because there is a space before Square):
<topic_expr>Triangle, Square</topic_expr>
With regard to the -deserialize option, this is not applicable to the Recording Service but to the Converter tool (rtirecconv). If you want to record deserialized, you will have to indicate that in the Recording Service configuration, via the tag <deserialize_mode>. Again, see the User's Manual for details.
I'm using the Dark Sky Forecast API to retrieve some weather information.
When I read the official doc, I found that the "option" section describes the usage of query parameters.
For example,
The API request may optionally be modified through the use of query parameters. It will respond to the following:
callback=[callback]: Return the API response as JSONP. Please use
caution when using this, since exposing your API key to the public is
a security hazard and, if abused, will result in the revokation of
your API key. However, if developing a personal- or internal-use app,
this is a convenient method of doing so.
units=[setting]: Return the
API response in units other than the default Imperial units. In
particular, the following settings are possible:
us: The default, as outlined above.
si: Returns results in SI units. In particular, properties now have the following units:
...
I know how to get the weather information by take advantages of the call
https://api.forecast.io/forecast/APIKEY/LATITUDE,LONGITUDE
But I don't know how to combine the query parameters with it.
Any ideas?
2015/10/23 UPDATE
Thank to Logan Kearns, using ? parameter solved my question. Make sure the query parameters are in lowercase.
https://api.forecast.io/forecast/APIKEY/LATITUDE,LONGITUDE?lang=zh-tw&units=si
This is how you change the units. I assume that other query parameters would be set in a similar manner, using the '?' to separate them.
https://api.forecast.io/forecast/APIKEY/LATITUDE,LONGITUDE?UNITS=us
Just an update, since url changed and with few other parameters:
You can add units to mention the type of unit conversion required
You can add exclude for excluding certain data in the response like hourly updates.

I'm using the google custom search api and want to create a search using the siteSearch:
https://www.googleapis.com/customsearch/v1?key=k&cx=cx&q=cocos2d&siteSearch=www.cocos2d-iphone.org&siteSearchFilter=i
and it works fine (returns all the result only from the given site).
Then I want to specify TWO sites to search so I tried to change the :
siteSearch=www.cocos2d-iphone.org
to
siteSearch=www.cocos2d-iphone.org www.XXXXXXXX.org
siteSearch=www.cocos2d-iphone.org|www.XXXXXXXX.org
siteSearch=www.cocos2d-iphone.org||www.XXXXXXXX.org
but none of these works.
hope someone can help here, thanks:)
Currently I don't believe you can specify more site through the query param siteSearch.
nevertheless you can configure your Custom Search Engine here: https://www.google.com/cse/manage/all
in the "Site to search" area.
This also works for excluding, as you can read here: https://support.google.com/customsearch/bin/answer.py?hl=en&answer=2631038&topic=2601037&ctx=topic
You cannot do this with the as_sitesearch parameter as that only accepts a single value. But you can achieve what you want with the as_q parameter, setting it to some value like: "site:google.com OR site:microsoft.com" - that will work in a similar way to this search.
The as_q parameter is documented here as:
The as_q parameter provides search terms to check for in a document.
This parameter is also commonly used to allow users to specify
additional terms to search for within a set of search results.
Examples q=president&as_q=John+Adams
Use "space" as seperator
Below is sample PHP code which works for me
$url="https://www.googleapis.com/customsearch/v1?key=k&cx=cx&q=cocos2d&siteSearch=".urlencode("www.cocos2d-iphone.org www.XXXXXXXX.org")."&siteSearchFilter=i"
