    - by glebreutov
    This code work without exceptions but post request does not work. What I do wrong?

  • Variable function name Javascript.

    - by Vladimir
    I'm sorting array: myArray.sort(comparators.some_comparator); and I have several comparator to choose from: comparators = { asc_firstname_comparator : function(o1, o2){ ... } desc_firstname_comparator : function(o1, o2){ ... } etc... } I want to write function which returns certain comparator depending on input data. It should figure out comparator from string inputs, something like this: function chooseComparator(field, order){ return "comparators."+order+"_"+field+"_comparator"; } So is it possible to pass only function name string to sort() method or I'll need to pass reference to correct comparator somehow?

  • Unique constraint on more than 10 columns

    - by tk
    I have a time-series simulation model which has more than 10 input variables. The number of distinct simulation instances would be more than 1 million, and each simulation instance generates a few output rows every day. To save the simulation result in a relational database, i designed tables like this. Table SimulationModel { simul_id : integer (primary key), input0 : string or numeric, input1 : string or numeric, ...} Table SimulationOutput { dt : DateTime (primary key), simul_id : integer (primary key), output0 : numeric, ...} My question is, is it fine to put an unique constraint on all of the input columns of SimulationModel table? If it is not a good idea, then what kind of other options do i have to make sure each model is unique?

  • ASP.Net mysterious behaviour

    - by kalan
    Does anyone have any idea why this works (expression in the if-clause) if (!(childNode.Roles != null && !Helper.HasEqualElements((string[])childNode.Roles, System.Web.Security.Roles.GetRolesForUser()))) AddNode(childNode, parentNode); And this doesn't if (childNode.Roles == null || Helper.HasEqualElements((string[])childNode.Roles, System.Web.Security.Roles.GetRolesForUser())) AddNode(childNode, parentNode); The problem is that the second if-clause sometimes doesn't work. Though it always works in debug mode, but it sometimes fails while running. And the strange thing is that these two pieces of code seems absolutely equal for me.

  • Do word boundaries work on symbol characters?

    - by Shawn31313
    I'm trying to implement word boundaries in my emoticons feature for a chat. But for some reason I can't seem to get the word boundaries to work. I am new to regex. So when I do: var reg = /\b\Hi\b/gi; var str = 'HiHiHi Hi HiHiHi Hi'; alert(str.replace(reg, '')); This happens: Jsfiddle It actually works fine, and does remove those 2 Hi's that are standing alone. But when I change the reg to an escaped smiley and then change the string: var reg = /\b\:\)\b/gi; var str = 'HiHi:) :) HiHiHi :)'; alert(str.replace(reg, '')); This happens: Jsfiddle It just doesn't work. The string stays the same. Is it that word boundaries can't be used on symbols? If so, how does Facebook do it on their chats?

  • How can I speed up line by line reading of an ASCII file? (C++)

    - by Jon
    Here's a bit of code that is a considerable bottleneck after doing some measuring: //----------------------------------------------------------------------------- // Construct dictionary hash set from dictionary file //----------------------------------------------------------------------------- void constructDictionary(unordered_set<string> &dict) { ifstream wordListFile; wordListFile.open("dictionary.txt"); string word; while( wordListFile >> word ) { if( !word.empty() ) { dict.insert(word); } } wordListFile.close(); } I'm reading in ~200,000 words and this takes about 240 ms on my machine. Is the use of ifstream here efficient? Can I do better? I'm reading about mmap() implementations but I'm not understanding them 100%. The input file is simply text strings with *nix line terminations.

  • How to look up an NHibernate entity's table mapping from the type of the entity?

    - by snicker
    Once I've mapped my domain in NHibernate, how can I reverse lookup those mappings somewhere else in my code? Example: The entity Pony is mapped to a table named "AAZF1203" for some reason. (Stupid legacy database table names!) I want to find out that table name from the NH mappings using only the typeof(Pony) because I have to write a query elsewhere. How can I make the following test pass? private const string LegacyPonyTableName = "AAZF1203"; [Test] public void MakeSureThatThePonyEntityIsMappedToCorrectTable() { string ponyTable = GetNHibernateTableMappingFor(typeof(Pony)); Assert.AreEqual(LegacyPonyTableName, ponyTable); } In other words, what does the GetNHibernateTableMappingFor(Type t) need to look like?

  • variable being weirdly deleted

    - by calccrypto
    im having a weird problem with one variable: its not being recognized but its still printing. i would post my code, but it is massive. the basic idea is: # pseudocode def function(stuff): <do stuff> # These are the only 2 conditions if tag == 3: pka = <a string> if tag == 4: pka = <a string> print pka # (1) print pka # (2) <do stuff not modifying pka> print pka # (3) if pka == 'RSA': <do stuff> elif pka == 'DSA': <do stuff> my code will error at (2). however, it will print out (1), (2), and (3), all of which are the same. is there any general explanation of why this is happening? if my code is really needed, i will post it, but otherwise, i would rather not due to its size update: now the code will error at the if statement after (3), saying UnboundLocalError: local variable 'pka' referenced before assignment even though (1),(2),(3) just printed

  • Does Postgresql varchar count using unicode character length or ASCII character length?

    - by bennylope
    I tried importing a database dump from a SQL file and the insert failed when inserting the string Mér into a field defined as varying(3). I didn't capture the exact error, but it pointed to that specific value with the constraint of varying(3). Given that I considered this unimportant to what I was doing at the time, I just changed the value to Mer, it worked, and I moved on. Is a varying field with its limit taking into account length of the byte string? What really boggles my mind is that this was dumped from another PostgreSQL database. So it doesn't make sense how a constraint could allow the value to be written initially.

I am a bit unclear about this and dun know why this is happening? What should i do to correct it?

  • Regular Expression - Password Validation is not working

    - by Kesavan
    Hi, I have to validate the password using regex. The password rule is like at least 1 uppercase and at least 2 numeric. It works fine except if the character comes at the end of the string. The regular expression which i am using is "^(?=.*\d.{2})(?=.*[A-Z].{1})(?=.*[@#$%^&+=].{2}).{8,12}$" Rules: minimum length = 8 minimum uppercase = 1 minimum numeric = 2 minimum special character = 1 It works for Test123$$, Test$123, TEST123$s, Test123$1, Test12$3 but it fails if the character specified comes at the end of the string like Test123$, Test$a12, Test12aa@, 123aa@@T. Please let me know if there is any fix for this.

  • How to efficiently deal with a large amount of HTML5 canvas pixel data over websockets

    - by user730569
    Using imageData = context.getImageData(0, 0, width, height); JSON.stringify(imageData.data); I grab the pixel data, convert it to a string, and then send it over the wire via websockets. However, this string can be pretty large, depending on the size of the canvas object. I tried using the compression technique found here: JavaScript implementation of Gzip but socket.io throws the error Websocket message contains invalid character(s). Is there an effective way to compress this data so that it can be sent over websockets?

  • Input multiple file names in windows open file dialog box

    - by goodiet
    Windows 7 allows you to select multiple files to open at once by using ctrl or shift key. The "File Name" input field at the bottom of the dialog box would auto populate with the following sample: "aaa.txt" "bbb.txt" "ccc.txt" "ddd.txt" I have 14,000 files in a folder and I only need a range of files (approx 500). When I use the shift key to select a range of files, the "File Name" field auto populates all 500 file names. Windows would cut me off at the 260th character when I try to paste in a pre-generated string into the "File Name" field. Is there a way to bypass the 260 character limit so it would accept my entire string with 500 file names?

  • Default datetime format in mySQL

    - by Davuz
    I'm coding to search data by compare datetime. In web form, user input value '2012-06-04' store in $_REQUEST['dateSearch']. I create datetime object from that: $dateObj = date_create_from_format("Y-m-d",$_REQUEST['dateSearch']); $dateParam = $dateObj->format("Y-m"); Then I use $dateParam in sql query to find data $sql = " SELECT * FROM `temp` as `t` WHERE `t`.`date` LIKE '$dateParam%' "; Everything is ok, but I'm not sure mySQL alway use only one datetime format "Y-m-d H:i:s". At here, $dateParam = $dateObj->format("Y-m"); I set default format is "Y-m". Is the default format never change? I don't want hard set format "Y-m-d H:i:s" in code, instead of, I think get format string from system to use is better. How do I get default datetime format string from mySQL???

  • isReachable in Java doesn't appear to be working quite the way it's supposed to

    - by Rayne
    I'm using Clojure, but I can read Java, so this isn't a Clojure specific question. This doesn't even seem to be working from Java. I'm trying to implement a bit of a 'ping' function using isReachable. The code I'm using is this: (.isReachable (java.net.InetAddress/getByName "www.microsoft.com") 5000) Translated to Java by a good friend of mine: public class NetTest { public static void main (String[] args) throws Exception{ String host = "acidrayne.net"; InetAddress a = InetAddress.getByName(host); System.out.println(a.isReachable(10000)); } } Both of these return false. I suppose I must be doin' it wrong, but Google research is telling me differently. I'm confuzzled!

  • Creating a new Guid inside a code snippet using c#

    - by Rob
    I want to make an intellisense code snippet using Ctl K + Ctl X that actually executes code when it runs... for example, I would like to do the following: <![CDATA[string.Format("{MM/dd/yyyy}", System.DateTime.Now);]]> But rather than giving me that string value, I want the date in the format specified. Another example of what I want is to create a new Guid but truncate to the first octet, so I would want to use a create a new Guid using System.Guid.NewGuid(); to give me {798400D6-7CEC-41f9-B6AA-116B926802FE} for example but I want the value: 798400D6 from the code snippet. I'm open to not using an Intellisense Code Snippet.. I just thought that would be easy.

  • How to correct character encoding in IE8 native json ?

    - by mike_t2e
    I am using json with unicode text, and having a problem with the IE8 native json implementation. <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <script> var stringified = JSON.stringify("?????? olé"); alert(stringified); </script> Using json2.js or FireFox native json, the alert() string is the same as in the original one. IE8 on the other hand returns Unicode values rather than the original text \u0e2a\u0e27\u0e31\u0e2a\u0e14\u0e35 ol\u00e9 . Is there an easy way to make IE behave like the others, or convert this string to how it should be ? And would you regard this as a bug in IE, I thought native json implementations were supposed to be drop-in identical replacements for json2.js ?
