  • Regex to match last space character

    - by Gerald Ferreira
    Hi There I need some help I am looking for a regex that would match the last space character in a string. I am using Javascript and Classic ASP If there is someone that could maybe point me in the right direction I have a long string of text which I trim to 100 characters. I would like to remove the last character to avoid a spelling mistake if the trim cuts a word due to the 100 characters limit regex.replace(/[ ]$.*?/ig, ''); Anybody with ideas? Thanks

  • Java : method to to print relative pathname?

    - by HH
    I am hesitant just to look at some env.vars and try to replace things with regexes. So is there a ready method to print relative pathnames system-independently? $ echo ~ /u/user $ pwd /u/user/OH/one/src $ echo "Like relative pathnames ~/OH/one/src, not /u/user/OH/one/src."

  • Does Python doctest remove the need for unit-tests?

    - by daniel
    Hi all, A fellow developer on a project I am on believes that doctests are as good as unit-tests, and that if a piece of code is doctested, it does not need to be unit-tested. I do not believe this to be the case. Can anyone provide some solid, ideally cited, examples either for or against the argument that doctests do not replace the need for unit-tests? Thank you -Daniel

  • How can i get a list of currently running threads in objective-C(iphone)

    - by krasnyk
    Is there a way to get the list of currently running threads in objective-C? I'm mostly interested in getting the NSThreads objects, cause i want to replace the assertion handler for each running thread? If such thing is not possible, maybe i could set my own selector to be invoked after any thread is spawn(so that i could do the assertion handler replacement over there)?

  • Deliver files from a web server from outside the web app

    - by Ankur
    Is there anyway to serve a file from a web server through the web, that is not within the web application. I am using Tomcat and a Java servlets based application. I don't want to put the files within the webapp because they are several 100GB and I will have to replace them every time I update the WAR if I put them inside it.

  • R Question: calculating deltas in a timeseries

    - by Jörg Beyer
    I have a timeseries of samples in R: > str(d) 'data.frame': 5 obs. of 3 variables: $ date: POSIXct, format: "2010-03-04 20:47:00" "2010-03-04 21:47:00" ... $ x : num 0 10 11 15.2 20 $ y : num 0 5 7.5 8.4 12.5 > d date x y 1 2010-03-04 20:47:00 0.0 0.0 2 2010-03-04 21:47:00 10.0 5.0 3 2010-03-04 22:47:00 11.0 7.5 4 2010-03-04 23:47:00 15.2 8.4 5 2010-03-05 00:47:00 20.0 12.5 In this example samples for x and y are taken every hour (but the time delta is not fix). The x and y values are always growing (like a milage counter in a car). I need the deltas, how much was the growth in between, something like this: 1 2010-03-04 20:47:00 0.0 0.0 2 2010-03-04 21:47:00 10.0 5.0 3 2010-03-04 22:47:00 1.0 2.5 4 2010-03-04 23:47:00 4.2 0.9 5 2010-03-05 00:47:00 4.8 4.1 And I also need the detlas per time (x and y delta, divided by the time - delta per hour) How would I do this in R?

  • SQLite is the CASE statement expensive?

    - by galford13x
    I'm wondering if using a CASE statement in SQLite (or other SQL engines) to replace data is not advised. For example lets say I have a query. SELECT Users, CASE WHEN Active = 0 THEN 'Inactive' WHEN Active = 1 THEN 'Active' WHEN Active = 2 THEN 'Processing' ELSE 'ERROR' AS Active FROM UsersTable; When is it better to create a reference table and perform a JOIN. In this case I would create a Table 'ActiveStatesTable' with ActiveID, ActiveDescription and perform the JOIN.

  • Unable to encode to iso-8859-1 encoding for some chars using Perl Encode module

    - by ppant
    I have a HTML string in ISO-8859-1 encoding. I need to pass this string to HTML:Entities::decode_entities() for converting some of the HTML ASCII codes to respective chars. To so i am using a module HTML::Parser::Entities 3.65 but after decode_entities() operation my whole string changes to utf-8 string. This behavior seems fine as the documentation of the HTML::Parse. As i need this string back in ISO-8859-1 format for further processing so i have used Encode::encode("iso-8859-1",$str) to change the string back to ISO-8859-1 encoding. My results are fine excepts for some chars, a question mark is coming instead. One example is single quote ' ASCII code (’) Can anybody help me if there any limitation of Encode module? Any other pointer will also be helpful to solve the problem. Thanks

  • Replacing multiple characters in C#

    - by Yassin
    How would i write a program, using the replace method, that rotates the vowels in a word? meaning the letter 'a' would be 'e', 'e' would be 'i', 'i' would be 'o', 'o' would be 'u', and finally 'u' would be 'a'. For example, the word "instructor" would be "onstractur". I hope someone can answer my problem.

  • Adding a loading gif to simple script

    - by bluedaniel
    Hello everyone, Im really really new to Javascript but Ive got this script that loads the contents of a url and everything works fine. I call the plannerSpin function with an onClick method on a button but how would I go about displaying an animated gif whilst all this is going on? var xmlHttp function plannerSpin(str) { xmlHttp = GetXmlHttpObject() if (xmlHttp == null) { alert("Browser does not support HTTP Request") return } var url = "/recipes/planner/data" xmlHttp.onreadystatechange = stateChanged xmlHttp.open("GET", url, true) xmlHttp.send(null) } function stateChanged() { if (xmlHttp.readyState == 4 || xmlHttp.readyState == "complete") { document.getElementById("recipe_planner_container").innerHTML = xmlHttp.responseText } } function GetXmlHttpObject() { var xmlHttp = null; try { // Firefox, Opera 8.0+, Safari xmlHttp = new XMLHttpRequest(); } catch (e) { // Internet Explorer try { xmlHttp = new ActiveXObject("Msxml2.XMLHTTP"); } catch (e) { xmlHttp = new ActiveXObject("Microsoft.XMLHTTP"); } } return xmlHttp; }

  • Evaluation of CTEs in SQL Server 2005

    - by Jammer
    I have a question about how MS SQL evaluates functions inside CTEs. A couple of searches didn't turn up any results related to this issue, but I apologize if this is common knowledge and I'm just behind the curve. It wouldn't be the first time :-) This query is a simplified (and obviously less dynamic) version of what I'm actually doing, but it does exhibit the problem I'm experiencing. It looks like this: CREATE TABLE #EmployeePool(EmployeeID int, EmployeeRank int); INSERT INTO #EmployeePool(EmployeeID, EmployeeRank) SELECT 42, 1 UNION ALL SELECT 43, 2; DECLARE @NumEmployees int; SELECT @NumEmployees = COUNT(*) FROM #EmployeePool; WITH RandomizedCustomers AS ( SELECT CAST(c.Criteria AS int) AS CustomerID, dbo.fnUtil_Random(@NumEmployees) AS RandomRank FROM dbo.fnUtil_ParseCriteria(@CustomerIDs, 'int') c) SELECT rc.CustomerID, ep.EmployeeID FROM RandomizedCustomers rc JOIN #EmployeePool ep ON ep.EmployeeRank = rc.RandomRank; DROP TABLE #EmployeePool; The following can be assumed about all executions of the above: The result of dbo.fnUtil_Random() is always an int value greater than zero and less than or equal to the argument passed in. Since it's being called above with @NumEmployees which has the value 2, this function always evaluates to 1 or 2. The result of dbo.fnUtil_ParseCriteria(@CustomerIDs, 'int') produces a one-column, one-row table that contains a sql_variant with a base type of 'int' that has the value 219935. Given the above assumptions, it makes sense (to me, anyway) that the result of the expression above should always produce a two-column table containing one record - CustomerID and an EmployeeID. The CustomerID should always be the int value 219935, and the EmployeeID should be either 42 or 43. However, this is not always the case. Sometimes I get the expected single record. Other times I get two records (one for each EmployeeID), and still others I get no records. However, if I replace the RandomizedCustomers CTE with a true temp table, the problem vanishes completely. Every time I think I have an explanation for this behavior, it turns out to not make sense or be impossible, so I literally cannot explain why this would happen. Since the problem does not happen when I replace the CTE with a temp table, I can only assume it has something to do with the functions inside CTEs are evaluated during joins to that CTE. Do any of you have any theories?

  • Python utf-8 decoding issue with hashlib.digest() method

    - by Sorw
    Hello StackOverflow community, Using Google App Engine, I wrote a keyToSha256() method within a model class (extending db.Model) : class Car(db.Model): def keyToSha256(self): keyhash = hashlib.sha256(str(self.key())).digest() return keyhash When displaying the output (ultimately within a Django template), I get garbled text, for example : ?????_??!`?I?!?;?QeqN??Al?'2 I was expecting something more in line with this : 9f86d081884c7d659a2feaa0c55ad015a3bf4f1b2b0b822cd15d6c15b0f00a08 Am I missing something important ? Despite reading several guides on ASCII, Unicode, utf-8 and the like, I think I'm still far from mastering the secrets of string encoding/decoding. After browsing StackOverflow and searching for insights via Google, I figured out I should ask the question here. Any idea ? Thanks !
