  • String intern puzzles

    - by Yob
    On this blog I found interesting String puzzles: --- Quote --- String te = "te", st = "st"; //"test".length(); String username = te + st; username.intern(); System.out.println("String object the same is: " + (username == "test")); prints String object the same is: true but uncomment the "test".length(); line and it prints String object the same is: false --- EoQ --- Being honest I don't understand why the outputs are different. Could you please explain me what's the cause of such behaviour?

  • On Memory Allocation and C++

    - by Arpan
    And I quote from MSDN http://msdn.microsoft.com/en-us/library/aa366533(VS.85).aspx: The malloc function has the disadvantage of being run-time dependent. The new operator has the disadvantage of being compiler dependent and language dependent. Now the questions folks: a) What do we mean that malloc is run-time dependent? What kind of dynamic memory allocation functions can be independent of run-time? This statement sounds real strange. b) new is language dependent? Of course it should be right? Are HeapAlloc, LocalAlloc etc language independent? c) From a pure performance perspective are the MSVC provided routines preferable? Arpan

  • How to know when the MPMoviePlayerController has been paused in iPhone?

    - by iPhoney
    I want to add an overlay view for my video when the video is paused by the user. Is there any way to get the pause notification from MPMoviePlayerController? According to Apple Doc, there should be ways to do this but I can't find which notification should I use for this purpose. Quote: In addition to being notified when playback finishes, interested clients can be notified in the following situations: -When the movie player begins playing, is paused, or begins seeking forward ... For more information, see the Notifications section in this reference.

  • Writing an Eval Procedure in Scheme?

    - by Planeman
    My problem isn't with the built-in eval procedure but how to create a simplistic version of it. Just for starters I would like to be able to take this in '(+ 1 2) and have it evaluate the expression + where the quote usually takes off the evaluation. I have been thinking about this and found a couple things that might be useful: Unquote: , (quasiquote) (apply) My main problem is regaining the value of + as a procedure and not a symbol. Once I get that I think I should just be able to use it with the other contents of the list. Any tips or guidance would be much appreciated.

  • Pass javascript array to php by using curly braces key name

    - by user7031
    My js code: $(function(){ var arr = new Array('jj', 'kk', 'oo'); $.post('test12.php', {'arr[]': arr}, function(data){ alert(data); }); }); PHP code: <?php echo print_r($_POST['arr']); The thing is,$.post receive a key named 'arr[]',it should be used in PHP as 'arr[]' instead of 'arr',but '$_POST['arr[]']' doesn't work,'arr' works.Which seems that Jquery might do something with curly braces '[]' before sending something to PHP. Secondly,when I remove the single quotas around 'arr[]',PHP can not receive anything by using $_POST['arr'];,I don't know why? Doing this task in a traditional way with no curly braces: $.post('test12.php', {arr: arr}, function(data){ alert(data); }); It works fine. So when sending javascript array to PHP,why bothering using single quote and curly braces like 'arr[]' instead of using a concise way like arr:arr My return result is Array( [0]=>jj [1]=>kk [2]=>oo ) 1 Notice there is a 1 under the array,why?

  • In the JSON spec, what does "Since the first two characters of a JSON text will always be ASCII characters" mean?

    - by dan gibson
    The spec is http://www.ietf.org/rfc/rfc4627.txt?number=4627 It contains this: Encoding JSON text SHALL be encoded in Unicode. The default encoding is UTF-8. Since the first two characters of a JSON text will always be ASCII characters [RFC0020], it is possible to determine whether an octet stream is UTF-8, UTF-16 (BE or LE), or UTF-32 (BE or LE) by looking at the pattern of nulls in the first four octets. What does it mean "Since the first two characters of a JSON text will always be ASCII characters [RFC0020]"? I've looked at RFC0020 but couldn't find anything about it. JSON could be {" or { " (ie whitespace before the quote.

  • MySQL ORDER BY returns things in (apparently) random order !?

    - by Luke H
    The following query: SELECT DISTINCT ClassName FROM SiteTree ORDER BY ClassName is returning things in no apparent order! I get the same result whether I quote column/table names, or use DISTINCT or not, or add ASC or DESC. I assumed the indexes might be broken, or something like this, so tried dropping and recreating. Also tried REPAIR TABLE and CHECK TABLE. The table collation is set to latin1_swedish_ci. All the textual columns are set to use UTF-8 and collation is set to utf8_general_ci What could be causing this?

  • C#: split a string into runs of characters, numbers and delimited strings and process it

    - by nrkn
    OK my regex is a bit rusty and I've been struggling with this particular problem... I need to split and process a string containing any number of the following, in any order: Chars (lowercase letters only) Quote delimited strings Ints The strings are pretty weird (I don't have control over them). When there's more than one number in a row in the string they're seperated by a comma. They need to be processed in the same order that they appeared in the original string. For example, a string might look like: abc20a"Hi""OK"100,20b With this particular string the resulting call stack would look a bit like: ProcessLetters( new[] { 'a', 'b', 'c' } ); ProcessInts( 20 ); ProcessLetters( 'a' ); ProcessStrings( new[] { "Hi", "OK" } ); ProcessInts( new[] { 100, 20 } ); ProcessLetters( 'b' ); What I could do is treat it a bit like CSV, where you build tokens by processing the characters one at a time, but I think it could be more easily done with a regex?

  • jquery dynamically genearate element id in a loop

    - by phil
    This is a loop in a function intending to create elements <li> and give each <li> an unique id. But it's not working. I suspect it's a simple syntax error with the use of quote in .attr(). But I can't get a straight answer from Google. for (i=0;i<array.length;i++) { //create HTML element of tag li $('#suggest').append("<li></li>"); $("li").attr("id",'li'+i); $('#li'+i).html(array[i]); }

  • Regex in javascript for enum datatype of mysql

    - by himadri
    Hello, I am working with php and mysql. I have one dropdown box where I am asking datatype of mysql field. Now, I want to put javascript validation for it. I am confused with the enum datatype. I am using regular expression /^[']{1}[^',^\\]+[']{1}$/. This is for one single value of enum values. It is working fine but issue is when I put single quote or backslash with backslash, it is valid but this regular expression shows it as invalid. For eg, 'a'b' is invalid but 'a\'b' is valid.

  • How is Magento using the module_name tag elements in the module config file

    - by zokibtmkd
    I found here that Magento is using these tags as custom config variables, but I still cannot understand where are they used and how. For example the Wishlist module has wishlist (same name as the module) xml tag in the config.xml file in which it defines: <item> <product_attributes> <visibility/> <url_path/> <url_key/> </product_attributes> </item> Where is this module using these configurations? Also if I was to build payment method, I have to add in my custom module config.xml a tag for sales and then for quote and so on... I also found other related questions, but most of the answers were that these tags can be anything, but I need to know how they are used by the system. Thank you in advance

  • What is the difference between an object's scope and it's context in javascript?

    - by DKinzer
    In the vernacular, scope and context have a lot in common. Which is why I get confused when I read references to both, such as in the quote below from an article on closures: Scope refers to where variables and functions are accessible, and in what context it is being executed. (@robertnyman) As far as I can tell, context is just a reference to an object. Can someone please explain what exactly is context, as used, for instance, in the jQuery syntax, $(selector, context). And is an object's scope the same at it's context?

  • Replacing whitespace with sed in a CSV (to use w/ postgres copy command)

    - by Wells
    I iterate through a collection of CSV files in bash, running: iconv --from-code=ISO-8859-1 --to-code=UTF-8 ${FILE} | \ sed -e 's/\"//g' | \ sed -e 's/, /,/g' \ > ${FILE}.utf8 Running iconv to fix UTF-8 characters, then the first sed call removes the double quote characters, and the final sed call is supposed to remove leading and trailing whitespace around the commas. HOWEVER, I still have a line like this in the saved file: FALSE,,,, 2.40,, The COPY command in postgres is kind of dumb, so it thinks " 2.40" is not valid syntax for a numeric value. Where am I going wrong w/ my processing of the CSV file? Thanks!

  • Importing CSV with line breaks in Excel 2007

    - by ph0enix
    I'm working on a feature to export search results to a CSV file to be opened in Excel. One of the fields is a free-text field, which may contain line breaks, commas, quotations, etc. In order to counteract this, I have wrapped the field in double quotes ("). However, when I import the data into Excel 2007, set the appropriate delimiter, and set the text qualifier to double quote, the line breaks are still creating new records at the line breaks, where I would expect to see the entire text field in a single cell. I've also tried replacing CR/LF (\r\n) with just CR (\r), and again with just LF (\n), but no luck. Has anyone else encountered this behavior, and if so, how did you fix it? TIA, -J

  • Nested Dynamic PHP Class

    - by user338844
    Alright, I may just need a terminology update, but I have been playing in Magento and Joomla, and they do references like $mage = new Mage; $mage->block('blockname'); where class Mage through some process I am failing to figure out is calling: class blockname extends something{ } Don't quote me on that code, however I am looking to do something like that where I have a file that I can do $myscript-block('blockname'); and it will load and call the file with class blockname. I hope that is not too confusing, but any help is appreciated. Thanks in advance!

  • escaping query string with special characters with python

    - by that_guy
    I got some pretty messy urls that i got via scraping here, problem is that they contain spaces or other special characters in the path and query string, here is some example http://www.example.com/some path/to the/file.html http://www.example.com/some path/?file=path to/file name.png&name=name.me so, is there an easy and robust way to escape the urls so that i can pass them to urlopen? i tried urlib.quote, but it seems to escape the '?', '&', and '=' in the query string as well, and it seems to escape the protocol as well, currently, what i am trying to do is use regex to separate the protocol, path name, and query string and escape them separately, but there are cases where they arent separated properly any advice is appreciated

  • Reading in a file - Warning Message in R

    - by Sheila
    I have a file that has 22268 rows BY 2521 columns. When I try to read in the file using this line of code: file <- read.table(textfile, skip=2, header=TRUE, sep="\t", fill=TRUE, blank.lines.skip=FALSE) I get the following error: Warning message: In scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : number of items read is not a multiple of the number of columns I also used this command to see what rows had an incorrect number of columns: x <-count.fields("train.gct", sep="\t", skip=2) which(x != 2521) and got back a list of about 20 rows that were incorrect. Is there a way to fill these rows with NA values? I thought that is what the "fill" parameter does in the read.table function, but it doesn't appear so. Any help would be greatly appreciated. Thank you.

  • How to know if your Unit Test Fixture is “right-sized”?

    - by leeand00
    How do you know if you "Test Fixture" is right-sized. And by "Test Fixture" I mean a class with a bunch of tests in it. One thing that I've always noticed with my test fixtures is that they get to be kind of verbose; seeing as they could also be not verbose enough, how do you get a sense of when your unit tests are the right size? My assumption is that (at least in the context of web development) you should have one test fixture class per page. I know of a good quote for this and it's: "Perfection is achieved, not when there is nothing left to add, but when there is nothing left to remove." - Antoine de Saint-Exupery.

  • Using the "IN" clause with a comma delimited string from the output of a replace() function in Oracle SQL

    - by Thomas
    Hi All, I have an comma delimited string which I want to use in an "IN" clause of the statement. eg: 100,101,102 Since In and "IN" clause I have to quote the individial strings, I use a replace function: eg: select ''''||replace('100,101,102',',',''', ''')||'''' from dual; The above query works, however, when I try to use the output of the above as an input to the "IN" clause, it returns no data.

Kindly help. eg: select * from employee where employee_number in ( select ''''||replace('100,101,102',',',''', ''')||'''' from dual); The above does not work. Please let me know what I am missing.

  • Extracting two strings from quotations in Java using regex?

    - by user656710
    Hi everyone, I'm new to using patterns and looked everywhere on the internet for an explanation to this problem. Say I have a string: String info = "Data I need to extract is 'here' and 'also here'"; How would I extract the words: here also here without the single quotes using a pattern? This is what I have so far... Pattern p = Pattern.compile("(?<=\').*(?=\')"); But it returns ( here and 'also here ) minus the brackets, that is just for viewing. It skips over the second piece of data and goes straight to the last quote... Thank you!

  • Cadr of a list involving assoc function

    - by user3619045
    I have looked around on the net and cant find an answer to my query. I would really appreciate if someone could provide a good answer without down rating this post. In Lisp car, cdr are used on data mode like '(whatever here) which makes sense to me. Now, in the book Land of Lisp the author is explaining how to build a text engine and suddenly he uses the following description to make a function. (defun describe-location (location nodes) (cadr (assoc location nodes))) Can I ask why is he doing a cadr on a list and how come it provides a response and not an error? shouldn't it be a data mode i.e with a quote in front of the opening bracket '(whatever here)? and also why is he using assoc as in (assoc location nodes) and not (assoc 'garden *nodes*) Isn't the second correct way to use assoc ? I may be missing the big picture and as such would really appreciate someone explaining these key points please. Many thanks!
