Revocation Checking
The process of revocation invalidates a certificate before its end validity date using one of the revocation codes mentioned in the previous section. A Microsoft CA publishes certificate status information in the form of CRLs. Third party products use this information to provide revocation information in other formats such as OCSP, SCVP and XKMS.
Prior to checking the status of a certificate, client must first checks a certificate to ensure that is trusted and it is time valid. Every issued certificate has a defined period in which the issuing...

EffectiveDate (thisupdate), NextUpdate and NextCRLPublish
(from http://blogs.technet.com/b/pki/archive/2008/06/05/how-effectivedate-thisupdate-nextupdate-and-nextcrlpublish-are-calculated.aspx)The validity time of a certificate revocation list (CRL) is critical for every public key infrastructure. By default, most applications verify the validity of certificates against a CRL.Two CRL types exist: base CRLs and delta CRLs. In case where no delta CRL is used, certificates are treated as invalid if the base CRL is not available or expired. If a delta CRL is in use, the delta and base CRL must be available...

Intermittent TimeoutException: The request channel timed out while waiting for a reply after 00:01:00 in WCF web service
I was experiencing this bug fairly long enough and without any success in reproduction.
Setting sendTimout to more than 1 default minute was not a decision, because this obviously was not an execution time problem. So as I have described in the previous post about WCF diagnostic, I analysed logs and found out that the response was actually sent from the server towards client which the client somehow failed to recieve. How is that? After pondering...

B: python 3.1:
>>> map(chr,[66,53,0,94])
<map object at 0x00AF5570>
To return a list in Python 3 the following should be used:

Accessing class from another module in Ruby on Rails
Modules in Ruby on Rails are not autoloadable in Ruby on Rails application.
Some hints on how to use a class from another module.
1. To make a module autoloadable the corresponding line should be commented out in application.rb
# Custom directories with classes and modules you want to be autoloadable.
# config.autoload_paths += %W(#{config.root}/extras)
2. Just use "::" before the class
3. Include the module in a code where the class is supposed to be used...
