erlang - How to work around limitation in io:setopts([{echo, false}]) with io:getline/1 -

-

I'm trying to put a password prompt in my app and io: get_line / 1 , The characters that write, they write stdout.

After the documentation, I am trying to do io: setopts ([echo, wrong}] returns the returns {error, enotsup} and do not start echoing successfully.

I open / dev / stdin and / dev / stdout directly because it is not a multi-platform Any recommendations for working around the range of echo with Io: setopts code>, or what I'm trying to do Find an alternative way to complete

Unfortunately, there is currently no easy way to do this. Older versions of scripts Io server Do not use either io: setopts ([[resonant, false]]) neither io: get_password () work with ascript. The best solution for reading the passwords is: 

  read-password ./script $ password   
 where ASScript is something like this:  
  #! / Usr / bin / env escript main ([password]) - & gt; Io: Format ("-> ~ p \ n", [password]).

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
