Why CancellationToken is separate from CancellationTokenSource?
I'm looking for a rationale of why .NET CancellationToken struct was introduced in addition to CancellationTokenSource class. I understand how the API is to be used, but want to also understand why it is designed that way.

How can I split a text into sentences?
...t you need. This group posting indicates this does it:
import nltk.data
tokenizer = nltk.data.load('tokenizers/punkt/english.pickle')
fp = open("test.txt")
data = fp.read()
print '\n-----\n'.join(tokenizer.tokenize(data))
(I haven't tried it!)

REST authentication and exposing the API key
...way, and we don't need REFERER. Still, it is secure:
When our get-csrf-token.js?apiKey=abc123 is requested:
Look up the key abc123 in the database and get a list of valid domains for that key.
Look for the CSRF validation cookie. If it does not exist, generate a secure random value and put it ...
What are the main uses of yield(), and how does it differ from join() and interrupt()?
...citly taken into account by the scheduler's heuristics
on its recent CPU allocation— thus, implicitly, a thread that has
yielded could be given more CPU when scheduled in the future.
(See the section on thread scheduling for more details on priorities
and scheduling algorithms.)

What is the difference between OpenID and SAML?
...ion and you can trust it at the application level. If users come with SAML tokens issued by an unknown provider, your application just refuses the authentication.
OpenID Connect vs SAML

This answer dates 2011 and at that time OpenID stood for OpenID 2.0. ...
Design for Facebook authentication in an iOS app that also accesses a secured web service
...
@TimLeung - My understanding is that an access token embeds the app ID, and that you can't have an access token WITHOUT an app ID baked into it.

Explain “claims-based authentication” to a 5-year-old
...ion. They do provide identifying information, but the intent is to use the token to access their service, not identify the user. An extension on that is OpenID which is intended to identify. In either case, the simple way to think about it (if not 100% accurate) is that they are just implementations...
Looping through the content of a file in Bash
...
Using for makes the input tokens/lines subject to shell expansions, which is usually undesirable; try this: for l in $(echo '* b c'); do echo "[$l]"; done - as you'll see, the * - even though originally a quoted literal - expands to the files in the c...
Creating an API for mobile applications - Authentication and Authorization
...n part of this in my projects is:
before login the user requests a login_token from the server. These are generated and stored on the server on request, and probably have a limited lifetime.
to login the application calculates the hash of the users password, then hashes the password with the login...
