How to skip invalid characters in stream in Java/Scala? -

-

उदाहरण के लिए मेरे पास कोड है 

  source.fromFile (नया फ़ाइल (पथ), "UTF-8")। GetLines ()   
 और यह अपवाद फेंकता  
  थ्रेड में अपवाद "मुख्य" java.nio.charset.MalformedInputException: इनपुट लंबाई = 1 java.nio.charset.CoderResult.throwException (CoderResult.java माह 60) पर sun.nio.cs.StreamDecoder.implRead (StreamDecoder.java319)   
 मैं डॉन 'कोई बात नहीं है अगर कुछ लाइनें नहीं पढ़ीं, लेकिन अमान्य वर्णों को कैसे छोड़ें और रीडिंग लाइनों को जारी रखने के लिए?   
 
 
 आप जिस तरह से वर्णसेट डिकोडिंग को कॉल करके अमान्य इनपुट को नियंत्रित कर सकते हैं, उसे प्रभावित कर सकते हैं।  
 <आम तौर पर  आपको कभी भी  वर्णसेटडिकोडर  ऑब्जेक्ट सीधे नहीं दिखाई देगा, क्योंकि यह आपके लिए पर्दे के पीछे बनाया जाएगा इसलिए यदि आपको इसे एक्सेस करने की आवश्यकता है, तो आपको एपीआई का उपयोग करने की आवश्यकता होगी जो आपको सीधे  CharsetDecoder  को निर्दिष्ट करने के बजाय (केवल एन्कोडिंग नाम या  Charset ) की अनुमति देता है। / P> 
 इस तरह के एपीआई का सबसे बुनियादी उदाहरण है:  
  InputStream in = ...; वर्णसेटडिकोडर डिकोडर = स्टैंडर्डचर्सेट्स.यूटीएफ_8.न्यूडीकोडर (); decoder.onMalformedInput (CodingErrorAction.IGNORE); रीडर रीडर = नए इनपुटस्ट्रीम रीडर (इन, डिकोडर);   
 ध्यान दें कि यह कोड जावा 7 वर्ग का उपयोग करता है, पहले के संस्करणों के लिए आप उसे (या इसके उपयोग से) प्रतिस्थापित कर सकते हैं।

php - Creating canonical URLs with custom route-classes -

-
I am trying to implement the canonical url and to combine with custom route classes. URL-SACAME is something like this: / category-x / article / 123 / category-y / article / 123 I am creating a custom route - the expansion of the class Zend_Controller_Router_Route_Regex and checks that the article is 123 and the correct category-name is included in the URL. If the article is in 123 square-X and the user is reaching square-y, then I want to redirect to the correct URL. But there is no clear possibility to do this directly to the roads. What is the best practice approach here? I often do this in my action controller like something ... // Get / Category-Y / Article / 123 $ $ article- & gt; URL is generated, and it contains / category-x / article / 123 if (this-> --request-> getRequestUri ()! = $ Article-> URL) {return $ this- & gt; ; _helper-> Redirector-> GoToUrl ($ paragraph-> url); } In this example, $ article-> The url will need ...

Mysql Local server hardware -

In anticipation of a live scenario, I am creating my entire site, which has a 500 MHz processor with 256 MB A very large 100 MHz RAM I have loaded my database with 200k + rows of garbage data, trying to test my queries. I have seen - obviously because of this, a large display hit all my FAQ using the index, although some 15+ to join (using all indexes) using MySQL To enable 16MB cache, which brings down the query times to nothing but what results? With a dynamic website, I can not see how the cache can help completely when I allow unique queries such as a search feature. I am also using the eaccelerator for PHP. When I use the COUNT (*) total with multiple code JOIN and WHERE , then 10 + There are other queries. Other queries that only get the same line or two do at the same level when I had only a few lines I also noticed that almost 99% of the CPU in CPU CPU stress during a query Comes. Basically I do not know whether the software is on the fault or too much of the h...

mysql - Formatting problem with PHP DateTime Difference when used as part of an equation -

I am trying to write a simple invoicing system. I want to use the Datetime Diff to calculate the cost of each invoice. I have so far: / * In this example $ dayLength and $ ratePerSec is not really the case, but now we use the hypotethical values ​​of 8.0 and 0.0054 Will * / $ date1 = new date time ("Time 1 Form Database", [DateTimeJonof Chase]); $ Date2 = new date time ("Time 2 Form Database", [Datetime Joneof Choice]); $ Diff = $ date2- & gt; Diff ($ date1); $ LenInSec = $ diff- & gt; Format ("% y") * 365 * $ dayLength * 3600 + $ diff- & gt; Format ("% d") * $ dayLength * 3600 + $ diff- & gt; Format ("% H") * 3600 + $ diff- & gt; Format ("% i") * 60 + $ diff- & gt; Format ("% s"); $ Cost = $ lenInSec * $ rate per second; When I try to output cost using $ lenInSec generated from the Deltaime Diff, I actually get weird results. Occasionally, in 1 and 3 out of 1 to 3 times, I get the...
