Perl - Ruby mapping? -

-

I was involved in a new project where Pearl should be one I'm coming from a good Ruby Foundation and Pearl and Ruby Want a quick introduction or mapping between me like I have heard that Pearl and Ruby are very close to the syntax (nothing is known about the FEATURES)

  1. Do you have any recommendations for me?
  2. Are you booking a great Pearl as an extended reference?
  3. The commonly used version is a second time in Nathan's book, although I would also like to mention that

Em> Pearl start There are two bonus features (1) It is freely available (and legally) (Note: this site is currently a deadline, and I am unsure whether it is temporary or not) and (2) it Learns Pearl and Intermediate Pearl combined thief is that it is time The primary thing that you might want ( Learning Perl gets faster and feels a bit higher - which can be a good thing.)

You can also see: Think in the opposite.

In the context of the volumes, 5.10.1 is stable, but you will come across a limit. Most of you will get 5.8.x and above, I suspect (just stays with Ruby 1.9.1 but you will still be able to use a lot of locations using 1.8.6 or above.)

To the extent I'm going in the opposite direction (I know Pearl quite well, and I'm using Ruby more often), I can mention things that stick to me:

  1. In Perl, you get a free conversion between strings and numbers Arise (and you do not need .to_f using ask clearly the result of a float or make a float of an item).
  2. Semi-colon option not are optional for the closing statement in Perl, and likewise they liked the brackets at least in Perl as compared to the gestures. (It gets complicated quickly, but for example you should be bracket for any condition, or for the test in while blocks.)
  3. 0 (String, integer and float), undef and empty string to be evaluated in bullion tests as false .
  4. There is no separate boolean true and false .
  5. You separate data types with sigils: $ foo is a scaler; @foo is an array; % foo is a hash (ARA especially bugs you may have: they are not the example variables.)
  6. Using the my keyword is obvious From there the scope of objects in the Pearl will be scaled.
  7. Array is automatically flattened in Pearl (it constantly bites me in Ruby.)
  8. Really, how big is your code in reference, reference, reference, Perl It depends on the understanding that in which context you have entered. It's for a start, but it's a big topic with many knox and craniés.

(Note that I did not mention 1000 pounds of gorilla in the room. OO is a part of Pearl and what can, but it is not in the center of Pearl, as In Ruby.)

MySql variables and php -

I am getting an error with php in order to format mysql_query () in php to format this string What is the right way? SELECT SELECT SELECT (*) Agents @AgentCount; User_Agent_English, User_Angent_Oursal, US.___Gent_Aginal, COUNT (User_Agent_Percade) ACC, COUNT (*) / (AgentCount) Percentage by agents user_agent_preser order DEC limit limit 50; In PHP, how am i setting $ query $ query = "SELECT count (*) agents @ agentcount; SELECT user_agent_parsed, User_agent_original , COUNT (user_agent_parsed) ascount, COUNT (*) / (@AgentCount) as a percentage by user_agent_parced by URI date DESC limit 50 "; This exact query will work properly if I put it in MySQL directly through a command line session. Do I need to release two separate php calls from mysql_query () and store the results first? I get the following error: There is an error in your SQL syntax; Instead of using a sub-selection and instead of using the 'SELECT user_agent_parsed, user_agent_original, ne...

url rewriting - How to implement the returnurl like SO in PHP? -

-
This URL should work even after the rewrite. Is this possible? Otherwise, I can only hardcoded everything If you are trying to create a login system with redirection You need to use the HTTP_REFERER header to find out where the user came from so that you can send it back there. The best way to do this is to use something like this in your login form: // - Login php & Lt; Input type = "password" name = "password" /> & Lt; Input type = "hidden" name = "returnrelale" value = "& lt ;? php echo $ redirectURL ;? & gt;" / & Gt; & Lt; / Form & gt; Please note that some ISP, browser or proxy will delete the referrer header, so you can not rely on each user to work fully. If you use a statement, to check whether the header exists or not, you can send those users back to the homepage or whatever. Edit If you are looking to use $ _SERVER ['REQUEST_URI'], if you are running Apache It sho...

Which Python client library should I use for CouchdB? -

-
I am starting to experiment with CouchDB because it looks like we have the right solution to certain problems That all the work will be on a new project, which does not have any legacy dependency, which the client library will suggest you use, and why? If we overlap any of the OS. Freeband is available only in the collection of its ports, but asks to use the library's project website. None of those people are Ubuntu, which is only with ships, since those two OSAs are not common in libraries, I am probably installing something from source (and hopefully if I have time, then Ubuntu and FreeBSD People pack the package). For those interests, I want to use CouchDB as a convenient intermediate storage space for data passed between different services - think of a message bus system, but less formalities with. For example, we have daemons that download and pars the web page, then send an interesting bit to other daemons for further processing. Many of them are ill-defined until the...
