• Wrong file encoding after Dist::Zilla

  - by xenoterracide

  How can I get mojibake to pass? this might be a bug in the contributors plugin. The character does not render correctly in perldoc, but does in my vim and in the extracted git log. # Failed test 'Mojibake test for blib/lib/Pod/Spell.pm' # at /home/xenoterracide/perl5/perlbrew/perls/perl-5.18.1/lib/site_perl/5.18.1/Test/Mojibake.pm line 168. # Non-UTF-8 unexpected in blib/lib/Pod/Spell.pm, line 431 (POD) here's a snippet from the source which should probably be looked at directly due to copy-paste maybe not catching an encoding issue. =item * Olivier Mengué <[email protected]> =back A little more vim exploration shows that :set filencoding is being changed to latin1 editing the file in vim seems to fix this, but since the file is being generated, how can I get it generated with the correct encoding?

• I can't use dashes in XPATH on iphone using libxml2

  - by user249488

  I'm trying to parse HTML data using KissXML for iphone. I've noticed that I can't have dashes in the id() tag, otherwise it won't evaluate. For example, if I'm trying to get the element at I would do id("foo") However, if I try to get at element , and I try id("foo-bar") the libxml2 XPATH engine doesn't seem to return anything. It works using the XPATH check for firefox, though. Anyone run into this issue and know of a reason why it's happening or have a workaround (besides using the absolute XPATH path?)

• How do I maximize a function in Mathematica which takes in a variable length list as input?

  - by Mike

  I have a time-series like function which gives an output based on a list of real numbers(i.e. you can run the function on a list of 1,2,3,... real numbers). The issue I'm encountering is how to maximize the function for a given list length(subject to a set of constraints). I could fix the function to a fixed number of real numbers(i.e. f [x_Real, y_Real] instead of f[x_List]) and treat x and y as the first two elements of the list, and call Maximize on the function, but this is not really elegant. I want to be able to easily change the number of elements in the list. What is the best way to optimize a function like I described, which takes a list as an argument, for a fixed list length?

• UIButton custom font vertical alignment

  - by Willshaw Media

  I've got a UIButton which uses a custom font, which is set when my view loads: - (void)viewDidLoad { [super viewDidLoad]; self.searchButton.titleLabel.font = [UIFont fontWithName: @"FONTNAME" size: 15.0 ]; } The problem I've got is that the font is appearing to float up of the center line. If I comment out this line, the default font appears vertically centered fine. But changing to the custom font breaks the vertical alignment. I'm getting the same issue on a Table Cell with a custom font too. Do I need to tell the view somewhere that the custom font is not as tall as other fonts? EDIT: I've just realized that the font I'm using is a Windows TrueType Font. I can use it fine in TextEdit on the Mac, only a problem with the alignment in my App

• Issues with the [embed] tag and fonts

  - by Legogo

  Hi, I have some issue with the [embed] tag. Even if I set the embedFonts property of the textfield to true the text doesn't show up. The thing is that it worked previously and after some changes (not related to fonts) it doesn't. I'd like to understand how the embed process for font works to find the error in my code. I declare : [Embed(source = 'asset/font.ttf', fontName="font", mimeType="application/x-font-truetype")] private static var font:String; to assign the font to the program. Then i call "font" when declaring my textFormat. Is the "fontName" property the link with the textformat ? I work with flashdevelop and the flex_sdk_4.0.0.14159 (the big adobe one, with air (~140mo)) Thx ! -Leg

• How to limit number of displayed items in html.dropdownlist?

  - by Remnant

  I have a html.dropdownlist on my webpage as follows: <%=Html.DropDownList("MyDropDown", Model.Data, new { @class = "dropdown"})%> I am populating the dropdown with ~80 items. The issue is that when I click the dropdown the list of items is rendered from the top of the screen to the bottom of the screen. How can I set up the dropdownlist so that it only displays a maximum of 20 items when the dropdown menu is clicked (i.e. user needs to scroll down to see items 21 - 80)? I was anticipating (!) that there would be a html.dropdownlist property to control the number of displayed items that would allow something like the following e.g.: <% =Html.DropDownList("MyDropDown", Model.Data, new { @class = "dropdown", rows ="20"}) %> From research I have been doing on the msdn website it appears that there is no such property and that each browser has its own rules of how many items are displayed in a dropdownlist (?). I am using IE6 and IE7.

• How can I load a sql "dump" file into sql alchemy

  - by JudoWill

  I have a large sql dump file ... with multiple CREATE TABLE and INSERT INTO statements. Is there any way to load these all into a SQLAlchemy sqlite database at once. I plan to use the introspected ORM from sqlsoup after I've created the tables. However, when I use the engine.execute() method it complains: sqlite3.Warning: You can only execute one statement at a time. Is there a way to work around this issue. Perhaps splitting the file with a regexp or some kind of parser, but I don't know enough SQL to get all of the cases for the regexp. Any help would be greatly appreciated. Will EDIT: Since this seems important ... The dump file was created with a MySQL database and so it has quite a few commands/syntax that sqlite3 does not understand correctly.

• Android-iPhone single codebase

  - by Lorenzo

  Is there a way, apart from using HTML and JavaScript on a web control, to have an (almost) single codebase for an application that should run on iOS and Android? The big issue is of course that they use a different language (Java for Android, Objective-C for iOS) for application development. It would be nice to have some sort of meta-language that will be translated in Java and in Objective-C. What about Flash? Adobe wasn't supposed to release a tool to create flash-based apps in iOS?

• Threading and pcap issues.

  - by cftmon

  I have a GUI program that allows a user a scan a network, the issue is that when the pcap_loop function is called, my GUI program becomes unresponsive.(the pcap_loop blocks the current thread). When i try to use pthreads, i got a SIGSEGV fault at the pcap_loop function.Why?It's as if the thread can't see the procPacket function itself. void procPacket(u_char *arg, const struct pcap_pkthdr *pkthdr, const u_char *packet) { //show packets here } void* pcapLooper(void* param) { pcap_t* handler = (pcap_t*) param; pcap_loop(handler, 900 ,procPacket, NULL ); } //some function that runs when a button is pressed //handler has been opened through pcap_open_live pthread_t scanner; int t = pthread_create(&scanner,NULL,&pcapLooper, &handler ); if(t) { std::cout << "failed" << std::endl; } pthread_join(scanner,NULL); //do other stuff.

• Hiding the console window in a system() call

  - by Justen

  Continuing from this question With each system call, the function constructs a set of parameters and sends them off to another program that is just console-based. Is there a way I can make it so that no console window pops up for each call? I've done a search but the ones that aren't a linker issue just aren't working for me. For instance, I tried the _execl call and System::Diagnostics::Process^ myProcess = gcnew System::Diagnostics::Process; but they aren't working. The _execl will bring a console window up, scroll a bunch of stuff (from the program I called I guess), then close the my app and not even do what it was supposed to do. The System::Diagnostics::Process^ myProcess = gcnew System::Diagnostics::Process; doesn't seem to execute what I want either because the output folder that should contain files, contains nothing. So I'm open for ideas.

• Count word occurrences in a text field with LINQ

  - by Yoann. B

  How can i get the occurrences count of a Word in a database text field With LINQ ? Keyword token sample : ASP.NET EDIT 4 : Database Records : Record 1 : [TextField] = "Blah blah blah ASP.NET bli bli bli ASP.NET blu ASP.NET yop yop ASP.NET" Record 2 : [TextField] = "Blah blah blah bli bli bli blu ASP.NET yop yop ASP.NET" Record 3 : [TextField] = "Blah ASP.NET blah ASP.NET blah ASP.NET bli ASP.NET bli bli ASP.NET blu ASP.NET yop yop ASP.NET" So Record 1 Contains 4 occurrence of "ASP.NET" keyword Record 2 Contains 2 occurrence of "ASP.NET" keyword Record 3 Contains 7 occurrence of "ASP.NET" keyword Collection Extraction IList < RecordModel (ordered by word count descending) Record 3 Record 1 Record 2 LinqToSQL should be the best, but LinqToObject too :) NB : No issue about the "." of ASP.NET keyword (this is not the goal if this question)

• Rails 3 routing - what's best practice?

  - by Mattias

  Hi guys, I'm trying out Rails, and I've stumbled across an issue with my routing. I have a controller named "Account" (singular), which should handle various settings for the currently logged in user. class AccountController < ApplicationController def index end def settings end def email_settings end end How would I set-up the routes for this in a proper manner? At the moment I have: match 'account(/:action)', :to => 'account', :as => 'account' This however does not automagically produce methods like account_settings_path but only account_path Is there any better practice of doing this? Remember the Account controller doesn't represent a controller for an ActiveModel. If this is in fact the best practice, how would I generate links in my views for the actions? url_to :controller => :account, :action => :email_settings ? Thanks!

• Disabling multitasking on iPhone 3GS using UIApplicationExitsOnSuspend not working

  - by NobleK

  Hello I am developing an iPhone app where I don’t want/need the multitasking capability and I want my app to initiate every time I open it. I have set the UIApplicationExitsOnSuspend property in the info.plist and it does work when I test it on my iPhone 4 and in the simulator (which is also an ”iPhone 4”). The app calls applicationDidEnterBackground followed by applicationWillTerminate. However, when testing it on my wifes iPhone 3GS the property seems to be completely ignored and the program gets suspended/resumed. Both phones are running iOS 4.2.1. Someone has also confirmed this issue in another thread, with no solutions unfortunately: iPhone: how to test if UIApplicationExitsOnSuspend is working? Is there something I am missing to make this work? Any other ways to accomplish this? Thanx in advance

• Possible to InvalidateVisual() on a given region instead of entire WPF control?

  - by Scott Bilas

  I have a complex WPF control that draws a lot of primitives in its OnRender (it's sort of like a map). When a small portion of it changes, I'd only like to re-issue render commands for the affected elements, instead of running the entire OnRender over. While I'm fine with my OnRender function's performance on a resize or whatever, it's not fast enough for mouse hover-based highlighting of primitives. Currently the only way I know how to force a screen update is to call InvalidateVisual(). No way to send in a dirty rect region to invalidate. Is the lowest granularity of WPF screen composition the UI element? Will I need to do my renders of primitives into an intermediate target and then have that use InvalidateVisual() to update to the screen?

• In iPhone OS, what UTI represents a plain ol' text file?

  - by Justin Searls

  I'm attempting to make use of the UIDocumentInteractionController mechanism in iPhone OS 3.2, but I'm struggling to figure out exactly how to construct a UTI that it likes. I've gotten as far as attempting to set "public.plain-text", but it's hard to test whether this is the correct UTI for a plain text document, since I can't tell whether the issue is that my iPad doesn't have any apps that support plain text import. (I figured Pages would, but I suppose perhaps not, since it will attempt and fail to load any files with the extension .pages, regardless of UTI). Any seasoned OS X developers that can help on this?

• Resizing Tab Bar Controller Views (iPhone dev)

  - by damiandawber

  Hello, I have an application set up where the window contains a tab bar controller and one of the tabs loads a NIB called 'ShowCaseView.xib': this file is owned by a custom ShowcaseViewController class. In the ShowcaseViewcontroller class I have added a UIScrollView object, like so: imageScrollView = [[UIScrollView alloc] initWithFrame:[[self view] bounds]]; [[self view] addSubview:imageScrollView]; The issue I am having is that this UIScrollView object extends beneath my tab bar controller. So I have had to reduce its insets manually: #define TAB_BAR_HEIGHT 48 . . UIEdgeInsets edgeInsets = UIEdgeInsetsMake(0, 0, TAB_BAR_HEIGHT, 0); [imageScrollView setScrollIndicatorInsets:edgeInsets]; So, Is it common to have to manually deduct the tab bar height from a view (whether this be by reducing the size of subviews or the View NIB in inspector)? Is there a way that I can tell a NIB's view loaded from a tab bar to resize itself automatically to NOT sit behind the tab bar? Cheers

• Will the app file be sync from dmgr side after we remove it from installedApps path in Websphere?

  - by wing2ofsky

  do you know whether the app file will be sync from dmgr side and regenerated after we remove it from installedApps path? i've got one issue recently from customer. That is, they uploaded one image file into WASNode installedApps app path manually. Afterwards, they removed that file manually again from installedApps app path. But after restarting the Application server process, that file has been regenerated under same installedApps path. So i suspect that file maybe has been resync from dmgr node, like app file under applications folder. However, first of all, i don't see that image file within application ear file from DMGR applications folder. Moreover, i made a test myself, if i deleted file from installedApps app path, that file never be regenerated any more even though the node sync completed. So does anybody know why? Thanks in advance

• MySQL floating point comparison issues

  - by Sharief

  I ran into an issue by introducing floating point columns in the MySQL database schema that the comparisons on floating point values don't return the correct results always. 1 - 50.12 2 - 34.57 3 - 12.75 4 - ...(rest all less than 12.00) SELECT COUNT(*) FROM `users` WHERE `points` > "12.75" This returns me "3". I have read that the comparisons of floating point values in MySQL is a bad idea and decimal type is the better option. Do I have any hope of moving ahead with the float type and get the comparisons to work correctly?

• Why is this postgres function failing only on one specifc database?

  - by Ollie Edwards

  I'm trying to fix an issue with a legacy database. The quote_literal function is not working for a specific database on an 8.4 install of postgres. Here's my results on a fresh test database: select quote_literal(42); quote_literal --------------- '42' (1 row) And now the same on the target db select quote_literal(42); ERROR: function quote_literal(integer) is not unique LINE 1: select quote_literal(42); ^ HINT: Could not choose a best candidate function. You might need to add explicit type casts. AIUI, the quote_literal(anyvalue) function should handle integer values ok, and this seems to be upheld by the first test. So I figured the quote_literal function must have been overridden in this db but no this doesn't seem to be the case. I could override it with a specific quote_literal(integer) function but I don't see why I should have to. The question is what is could be causing the failure of this function in this specific database whilst not affecting the fresh db?

  Hi, I have moodle1.9 installed on my system and writing some custom reports. I want to retrieve list of students registered for a particular course. I have user profile field usercategoryid through which i figure out for which category he has enrolled. Course belongs to a particular category.

I have written a query to retrieve the users who have registered for a particular category for e.g. Financial Planning 2010. But the issue is that i now want users who have registered for a particular course for e.g. Insurance Planning. There is a relation between course and course category but i am unable to find out the table where course and user information is linked. Please help me on this Thanks
