  • Should I allow my clients to open tickets/access trac?

    - by Mark
    I just installed trac for this project I'm working on, since it's turned out to be a bit bigger than I anticipated. I've added a bunch of tickets with my clients requests which come in the form of emails, phone calls, and meetings. I've also added some stuff I know needs to be done/fixed but they haven't specifically requested. Should I grant them access to trac so they can submit the tickets themselves so I don't have to keep translating (words into tickets) for them? They're very non-technical, so I'm not sure how well it would work; they might open tickets and not provide enough detail, or get confused by all the different fields. If your answer is "no", should I at least let them view the tickets, so they can see what I'm working on, what's been done, hasn't been done? So they can stop calling me to say "xxx doesn't work" when it's already a ticket? (Not that this would work, but I could at least respond "see ticket #42")

  • Why RichTextBox lose format after appending new String?

    - by user556526
    Hi guys I have aproblem with rich text box string color: I have the richtexbox that user type a message in it. I mark up each word that exist in my dictionary. I use this code for it: this.inputTextAreaRtb.Text=this.inputTextAreaRtb.Text.Remove(startCoordinate, endCoordinate - startCoordinate); this.inputTextAreaRtb.SelectionStart = this.inputTextAreaRtb.Text.Length; this.inputTextAreaRtb.SelectionLength = 0; this.inputTextAreaRtb.SelectionFont = new System.Drawing.Font( "David", 12, FontStyle.Underline); this.inputTextAreaRtb.SelectionColor = Color.DarkBlue; this.inputTextAreaRtb.AppendText(_word); this.inputTextAreaRtb.SelectionColor = this.inputTextAreaRtb.ForeColor; this.inputTextAreaRtb.SelectionFont = new System.Drawing.Font( "David", 12, FontStyle.Regular); But each time if I already marked up a word a loose formatting of words that already formatted. Any ideas of this problem?

  • Static variable for optimization

    - by keithjgrant
    I'm wondering if I can use a static variable for optimization: public function Bar() { static $i = moderatelyExpensiveFunctionCall(); if ($i) { return something(); } else { return somethingElse(); } } I know that once $i is initialized, it won't be changed by by that line of code on successive calls to Bar(). I assume this means that moderatelyExpensiveFunctionCall() won't be evaluated every time I call, but I'd like to know for certain. Once PHP sees a static variable that has been initialized, does it skip over that line of code? In other words, is this going to optimize my execution time if I make a lot of calls to Bar(), or am I wasting my time?

  • Filtering out unique rows in MySQL

    - by jpatokal
    So I've got a large amount of SQL data that looks basically like this: user | src | dst 1 | 1 | 1 1 | 1 | 1 1 | 1 | 2 1 | 1 | 2 2 | 1 | 1 2 | 1 | 3 I want to filter out pairs of (src,dst) that are unique to one user (even if that user has duplicates), leaving behind only those pairs belonging to more than one user: user | src | dst 1 | 1 | 1 1 | 1 | 1 2 | 1 | 1 In other words, pair (1,2) is unique to user 1 and pair (1,3) to user 2, so they're dropped, leaving behind only all instances of pair (1,1). Any ideas? The answers to the question below can find the non-unique pairs, but my SQL-fu doesn't suffice to handle the complication of requiring that they belong to multiple users as well.

  • What algorithm would you use to code a parrot?

    - by Phil H
    A parrot learns the most commonly uttered words and phrases in its vicinity so it can repeat them at inappropriate moments. So how would you create a software version? Assuming it has access to a microphone and can record sound at will, how would you code it without requiring infinite resources? The best I can imagine is to divide the stream using silences in the sound, and then use some pattern recognition to encode each one as a list of tokens, storing new ones as you meet them. Hashing the token sequences and counting occurrences in a database, you could build up a picture of the most frequently uttered phrases. But given the huge variety in phrases, how do you prevent this just becoming a huge list? And the sheer number of pairs to match would surely generate lot of false positives from the combinatorial nature of matching. Would you use a neural net, since that's how a real parrot manages it? Or is there another, cleverer way of matching large-scale patterns in analogue data?

  • Need some ideas on how to acomplish this in Java (parsing strings)

    - by Matt
    Sorry I couldn't think of a better title, but thanks for reading! My ultimate goal is to read a .java file, parse it, and pull out every identifier. Then store them all in a list. Two preconditions are there are no comments in the file, and all identifiers are composed of letters only. Right now I can read the file, parse it by spaces, and store everything in a list. If anything in the list is a java reserved word, it is removed. Also, I remove any loose symbols that are not attached to anything (brackets and arithmetic symbols). Now I am left with a bunch of weird strings, but at least they have no spaces in them. I know I am going to have to re-parse everything with a . delimiter in order to pull out identifiers like System.out.print, but what about strings like this example: Logger.getLogger(MyHash.class.getName()).log(Level.SEVERE, After re-parsing by . I will be left with more crazy strings like: getLogger(MyHash getName()) log(Level SEVERE, How am I going to be able to pull out all the identifiers while leaving out all the trash? Just keep re-parsing by every symbol that could exist in java code? That seems rather lame and time consuming. I am not even sure if it would work completely. So, can you suggest a better way of doing this?

  • Detect what is selected (highlighted) or clicked within an element on a page?

    - by Fog Cook
    How would one go about detecting what has been selected on a page in a browser? Example: Click, hold, select 3 words and 1 image on a page, release. Sub-question: How to detect what letter someone clicked on? Without using: A span injector breaking everything up OR a WYSIWYG plugin I'm hoping this isn't just a type of browser interaction you can't detect. There could be many uses, but my goal is a simple 'live' page editor, or at least a way to know what someone is clicking on/selecting aside from just the id of an element.

  • Conditionally setting the font color of an item in a drop down box in JSF

    - by Greg
    I'm a newbie to web programming, so please bear with me. I am using JSF 1.2 and I want to conditionally set the color of the items in my drop down list. In other words, I have a collection of items that, along with a key and a value, also have a boolean property, warning, that is dynamically set by user action. I want the drop down to show all of the items, but those whose warning property is set to true should be displayed in red. I assume I have to extend the SelectItem class to add in the boolean property. How do I then conditionally set the color of the font of those items whose warning property is set to true in my JSP pages? Thanks in advance

  • Are there libraries or techniques for collecting and weighing keywords from a block of text?

    - by Soviut
    I have a field in my database that can contain large blocks of text. I need to make this searchable but don't have the ability to use full text searching. Instead, on update, I want my business layer to process the block of text and extract keywords from it which I can save as searchable metadata. Ideally, these keywords could then be weighed based on the number of times they appear in the block of text. Naturally, words like "the", "and", "of", etc. should be discarded as they just add a lot of noise to the search. Are there tools or libraries in Python that can do this filtering or should I roll my own?

  • FLEX: why the event is only listened by the dispatcher component ?

    - by Patrick
    hi, I've a parent (Canvas) with many children (LinkButtons) The linkButtons trigger an event to communicate between them: dispatchEvent(new SameBookmarkEvent("SameBookmarkEvent", bookmark.name)); and all linkButtons have a listener this.addEventListener("SameBookmarkEvent", highlightMe); ... private function highlightMe(e:SameBookmarkEvent):void { //do something } Now, the issue is that the event is only listened by the dispatcher child. In other words, only the child triggering the event, is receiving it. I was wondering what's wrong with it, and if I should add a listener to the parent (Canvas)... I basically need the children (LinkButton) communicate between them

  • ORM Against a Service-Wrapped Data Source

    - by blaster
    We are tasked with migrating an existing set of entities (currently POCOs persisted with NHibernate against an MSSQL database) to now persist to some kind of web service (yet to be built, either RESTful or SOAP-based, and that we control). I like how NHibernate encapsulates the persistence concerns and lets us maintain a logic-rich, persistence-agnostic domain model. Is there any way to make NHibernate talk to a web service at the back end instead of a SQL database directly? In other words, can "service instead of SQL database" be treated as a persistence implementation detail and allow us to continue to use NHibernate? Am I asking the right question? :)

  • Is call to function object inlined?

    - by dehmann
    In the following code, Foo::add calls a function via a function object: struct Plus { inline int operator()(int x, int y) const { return x + y; } }; template<class Fct> struct Foo { Fct fct; Foo(Fct f) : fct(f) {} inline int add(int x, int y) { return fct(x,y); // same efficiency adding directly? } }; Is this the same efficiency as calling x+y directly in Foo::add? In other words, does the compiler typically directly replace fct(x,y) with the actual call, inlining the code, when compiling with optimizations enabled?

  • C# Regex: only letters followed by an optional .

    - by TheDude
    Hello, I am looking for a way to get words out of a sentence. I am pretty far with the following expression: \b([a-zA-Z]+?)\b but there are some occurrences that it counts a word when I want it not to. E.g a word followed by more than one period like "text..". So, in my regex I want to have the period to be at the end of a word zero or one time. Inserting .? did not do the trick, and variations on this have not yielded anything fruitful either. Hope someone can help!

  • jQuery inline text scrolling/rotating/carousel effect

    - by Adam Pope
    I trying to create an animation with JQuery that scrolls 1 word in a sentence. For example, I am a nice sententce of text with a MAGIC word in it OTHER HIDDEN WORDS After a second or so, MAGIC would move upwards and OTHER would scroll into view. I've tried playing with a few carousel plugins but I can't seem to get the effect working. Some seem to have so many nested divs that they refuse to display inline, others have issues when one word is longer than another. Does anybody know of a plugin that could make this possible? Is this even possible?

  • Interpolation on Cubism graphs

    - by Abe Stanway
    Cubism was designed, by mbostock's own words, for maximum information density - which means it generally wants to display one datapoint per pixel. While this is useful in many cases, it doesn't help when your data itself is not that dense. In these cases, you get ugly, staccato-style graphs like so: Is there a way to interpolate my data/graph within Cubism to show a nice, smoothed graph? EDIT: After adding keepLastValue to the metric, I get this: Here is the same data as shown in Graphite: I would like to smooth the Cubism view to look more like Graphite (with the added awesomeness of the horizon overplotting)

  • Java regex skipping matches

    - by Mihail Burduja
    I have some text; I want to extract pairs of words that are not separated by punctuation. Thi is the code: //n-grams Pattern p = Pattern.compile("[a-z]+"); if (n == 2) { p = Pattern.compile("[a-z]+ [a-z]+"); } if (n == 3) { p = Pattern.compile("[a-z]+ [a-z]+ [a-z]+"); } Matcher m = p.matcher(text.toLowerCase()); ArrayList<String> result = new ArrayList<String>(); while (m.find()) { String temporary = m.group(); System.out.println(temporary); result.add(temporary); } The problem is that it skips some matches. For example "My name is James", for n = 3, must match "my name is" and "name is james", but instead it matches just the first. Is there a way to solve this?

  • ASP.NET ~ remotely invoking an ASP.NET page

    - by eponymous23
    I have two servers running IIS, say, Server-A and Server-B. Server-A is in the DMZ, visible to all users; Server-B is not in the DMZ. I need to provide a way for users to invoke a page on Server-A which will in turn remotely request a page on Server-B, transparently to the user. In other words, Server-A needs to do this on behalf of the user because the user does not have visibility to Server-B. Is this possible and if so, what is the best method to do this?

  • JavaScript eval() with `this`

    - by mojuba
    If I define a JavaScript code snippet in my HTML, like so: <div id=myElem onMyUpdate="alert('Update called for ' + this.id)">... then what is the most elegant way of evaluating it from within JavaScript with this properly assigned? What I came up with so far is something like this: if (elem.hasAttribute('onMyUpdate')) (function () { eval(elem.getAttribute('onMyUpdate')) }).call(elem); which looks terrible (to me), but works. Any better/more elegant alternatives? MDN says there used to be the second argument to eval() for doing just that but it's deprecated now; MDN then suggests to use operator with() instead, which, if you follow the link provided, turns out to be made deprecated by the latest standard. Dead end, in other words. (As a side note, StackOverflow ignores the word this in search terms and thus it may miss relevant answers - is there a way of telling it not to?) Edit: I forgot to mention: no jQuery please, just vanilla JavaScript

  • python parallel computing: split keyspace to give each node a range to work on

    - by MatToufoutu
    My question is rather complicated for me to explain, as i'm not really good at maths, but i'll try to be as clear as possible. I'm trying to code a cluster in python, which will generate words given a charset (i.e. with lowercase: aaaa, aaab, aaac, ..., zzzz) and make various operations on them. I'm searching how to calculate, given the charset and the number of nodes, what range each node should work on (i.e.: node1: aaaa-azzz, node2: baaa-czzz, node3: daaa-ezzz, ...). Is it possible to make an algorithm that could compute this, and if it is, how could i implement this in python? I really don't know how to do that, so any help would be much appreciated

  • rearranging a list of months

    - by MacUsers
    How can I list the numbers 01 to 12 (one for each of the 12 months) in such a way so that the current month always comes last where the oldest one is first. In other words, if the number is grater than the current month, it's from the previous year. e.g. 02 is Feb, 2011 (the current month right now), 03 is March, 2010 and 09 is Sep, 2010 but 01 is Jan, 2011. In this case, I'd like to have [09, 03, 01, 02]. This is what I'm doing to determine the year: for inFile in os.listdir('.'): if inFile.isdigit(): month = months[int(inFile)] if int(inFile) <= int(strftime("%m")): year = strftime("%Y") else: year = int(strftime("%Y"))-1 mnYear = month + ", " + str(year) I don't have a clue what to do next. What should I do here?

  • How do I deal with connection strings in a Click-Once application?

    - by Pwninstein
    I'm thinking of building a Click-Once application, and am trying to wrap my head around how to handle the whole connection string issue. The problem is the following: I want to use EF to get data directly from each client, thus requiring each client to have a connection string configured (this is not the issue). How do I deal with clients that are not on the same domain as the SQL Server being queried? In other words, if I tried to run my app from home as opposed to from work, what should my connection string look like? Would I need to configure my SQL Server differently to allow this scenario? Thanks in advance!

  • Design best practice - best way to handle user selection

    - by user1457227
    I'm an experienced developer (WPF) moving over to Android development. My question: an app I am developing allows the user to browse their local storage (such as SDCARD) and select a file. Now, should I simply create a new Activity (after the user has made a selection) to handle what I want to have the app do with that chosen file, -or- is the better approach to pass the path/name of the selected file back to the main Activity and let IT launch the next Activity? In other words, is the better practice to have the main Activity launch other (support) activities, or is it perfectly ok and normal to have one activity chain to another and on and on? Thanks!

  • In PLT scheme, can I export functions after another function has been called?

    - by Jason Baker
    I'm trying to create a binding to libpython using scheme's FFI. To do this, I have to get the location of python, create the ffi-lib, and then create functions from it. So for instance I could do this: (module pyscheme scheme (require foreign) (unsafe!) (define (link-python [lib "/usr/lib/libpython2.6.so"]) (ffi-lib lib)) This is all well and good, but I can't think of a way to export functions. For instance, I could do something like this: (define Py_Initialize (get-ffi-obj "Py_Initialize" libpython (_fun -> _void))) ...but then I'd have to store a reference to libpython (created by link-python) globally somehow. Is there any way to export these functions once link-python is called? In other words, I'd like someone using the module to be able to do this: (require pyscheme) (link-python) (Py_Initialize) ...or this: (require pyscheme) (link-python "/weird/location/for/libpython.so") (Py_Initialize) ...but have this give an error: (require pyscheme) (Py_Initialize) How can I do this?

  • mysql syntax how to add a third table to $query

    I have code: $query = "SELECT a.*, c.name as categoryname, c.id as categoryid". " FROM #__table_one as a". " LEFT JOIN #__table_two c ON c.id = a.catid"; $query .= " WHERE a.published = 1" ." AND a.access <= {$aid}" ." AND a.trash = 0" ." AND c.published = 1" ." AND c.access <= {$aid}" ." AND c.trash = 0" ; I would like to add a third table ('__some_table') for the parts of the query where a.publish, a.access and a.trash. In other words, I want these fields to be retrieved from another table, not "#__table_one", but I do not know how to incorporate the #__some_table into the current query I imagine the JOIN command can help me, but I do not know how to code mysql Thank you,
