• Censoring selected words (replacing them with ****) using a single replaceAll?

  - by aioobe

  I'd like to censor some words in a string by replacing each character in the word with a "*". Basically I would want to do String s = "lorem ipsum dolor sit"; s = s.replaceAll("ipsum|sit", $0.length() number of *)); so that the resulting s equals "lorem ***** dolor ***". I know how to do this with repeated replaceAll invokations, but I'm wondering, is this possible to do with a single replaceAll?

• SQL 2008 CASE statement aggravation...

  - by Brad

  Why does this fail: DECLARE @DATE VARCHAR(50) = 'dasf' SELECT CASE WHEN ISDATE(@DATE) = 1 THEN CONVERT(date,@DATE) ELSE @DATE END Msg 241, Level 16, State 1, Line 2 Conversion failed when converting date and/or time from character string. Why is it trying to convert dasf to date when it clearly causes ISDATE(@DATE) = 1 to evaluate to false... If I do: SELECT ISDATE(@DATE) The return value is 0.

• Hibernate query cache automatically refreshed on external update?

  - by artgon

  I'm creating a service that has read-only access to the database. I have a query cache and a second level cache enabled (READ_ONLY mode) in Hibernate to speed up the service, as the tables being accessed change rarely. My question is, if someone goes into the DB and changes the tables manually (i.e. outside of Hibernate), does the cache recognize automatically that it needs to be cleared? Is there a time limit on the cache?

• Validate a string

  - by Activist

  I'm not that good with regular expressions... I need a JavaScript regular expression that will do the following: The string can contain letters (upper and lower case), but not punctuations such as éàïç... The string can contain numbers (0..9) anywhere in the string, except on the first position. The string can contain underscores (_). Valid strings: foo foo1 foo_bar fooBar Invalid strings: 1foo -- number as first character foo bar -- space föo -- punctuation ö Many thanks!

• Why can't your switch statement data type be long Java?

  - by Fostah

  Here's an excerpt from Sun's Java tutorials: A switch works with the byte, short, char, and int primitive data types. It also works with enumerated types (discussed in Classes and Inheritance) and a few special classes that "wrap" certain primitive types: Character, Byte, Short, and Integer (discussed in Simple Data Objects ). There must be a good reason why the long primitive data type is not allowed. Anyone know what it is?

• Where does getopt_long store an unrecognized option?

  - by Rob Kennedy

  When getopt or getopt_long encounters an illegal option, it stores the offending option character in optopt. When the illegal option is a long option, where can I find out what the option was? And does anything meaningful get stored in optopt then? I've set opterr = 0 to suppress the automatically printed error message. I want to create my own message that I can print or log where I'd like, but I want to include the name of the unrecognized option.

• Android - What is mediarecorder's maximum maxfilesize?

  - by andy_spoo

  Android - What is the maximum file size that setMaxFileSize can be set to in respect to Androids mediarecorder? I know it's somewhere between 4147483650 and 5147483650. Why is there a limit in the first place? I'm recording on to a SDCARD, detecting the size of the cards space before we run. "ERROR/AuthorDriver(31): setParameter(max-filesize = 7270309850) failed with result -5" "ERROR/AuthorDriver(31): Ln 903 handleSetParameters("max-filesize=7270309850") error" "ERROR/AndroidRuntime(409): java.lang.RuntimeException: setMaxFileSize failed."

• Python - Find where in string regex match was found?

  - by nb

  I'm currently using regular expressions to search through RSS feeds to find if certain words and phrases are mentioned, and would then like to extract the text on either side of the match as well. For example: String = "This is an example sentence, it is for demonstration only" re.search("is", String) I'd like to know where the is was found so that I can extract and output something like this: 1 match found: "This is an example sentence" I know that it would be easy to do with splits, but I'd need to know what the index of first character of the match was in the string, which I don't know how to find
