ruby - Why does Eclipse complain about "Feature envy" smell in my code? -

-

Eclipse (RedRails) निम्नलिखित कोड में शिकायत करते हैं: 

  यदि input_text = ~ /^(---\s*\n.*?\n?)(---.*?)/m content_text = input_text [($ 1. आकार + $ 2. आकार) ..- 1] # चेतावनी $ 1 हेडर = YAML.load ($ 1) @content = content_text.strip () @title = header ["title"] अंत

मेरी समझ यह है कि मैं इस चेतावनी को अनदेखा करने के लिए सुरक्षित है। लेकिन मैं भटक रहा हूं कि यह चेतावनी क्यों उत्पन्न होती है। मैं समझ नहीं सकता कि मैं कैसे $ 1.size और $ 1 के लिए विधि निकाल सकते हैं।

स्ट्रिंग में होनी चाहिए। स्ट्रिंग लंबाई जोड़ते समय यह बेशक बकवास है, लेकिन आपके मामले में $ & amp; (पूर्ण मिलान स्ट्रिंग) का उपयोग करके कोड सरल किया जा सकता है:

< प्री> इनपुट_टेक्स्ट [$ & amp;। आकार .. - 1]

sql server - SQL Query - Delete duplicates if more than 3 dups? -

-
Is there an elegant SQL statement for deleting duplicate records in a table, but only if X is the number of duplicates? So it allows up to 2 or 3 duplicates, but what is it? At present I have a statement that does the following: Remove table from table, left outer (duplicate from table group like Triad, Diplo 1, Duplex 2) 1, Select Max (ID) by Dupl 2. Maintenance as TDI) = Maintenance. Where are kept. Road is empty This works very well. But what I want to do now will only remove those lines, if they have more than 2 duplicates. Thanks with in the form of CT (select row_member ( )) (Divol1 by split, dupol2 sequence by id) from table as rn) from cte where rn & gt; 2; - or & gt; 3 etc. The query is being classified by a 'line number' for each record, (Dupl 1, Dupl 2) and ordered by ID. In fact, this line number is calculated as 'duplicate', which has the same duplicate 1 and duplex 2 and then specifies the number 1, 2, 3. If you want to keep ...

c - Different access levels with PAM -

-
Currently I have a graphical application that has two levels of access, operator and administrator. Login and authentication are all homemade and I want to switch applications using PAM instead. I'm not sure what is the right way to do this. Correct me if I am wrong, but it looks like PAM boils down to "yes" or "no" to check - yes you can use this service, or you do not There is no provision based on the various levels of admission in which the user is logging on. I should be able to tell who is the operator and who is the administrator, though, and it is possible that I probably want to be able to do this through PAM. / P> So my idea is that I have two services with two different configurations , /etc/pam.d/pamdemo and Administrator /etc/pam.d/pamdemo-admin My application will then try to authenticate before pamdemo-admin , and if it is unsuccessful then pamdemo . If both fail, then admission is denied. Am I on the right track or am I complete...
