  • C: Incompatible types?

    - by Airjoe
    #include <stdlib.h> #include <stdio.h> struct foo{ int id; char *bar; char *baz[6]; }; int main(int argc, char **argv){ struct foo f; f.id=1; char *qux[6]; f.bar=argv[0]; f.baz=qux; // Marked line return 1; } This is just some test code so ignore that qux doesn't actually have anything useful in it. I'm getting an error on the marked line, incompatible types when assigning to type ‘char *[6]’ from type ‘char **’ but both of the variables are defined as char *[6] in the code. Any insight?

  • Trying to Install Rails 3

    - by Rob Fuller
    I'm trying to install Rails 3 on a brand new MacBook Pro running OS X 10.6.3, Ruby 1.8.7, and Rails 2.3.5 and I'm wondering if I've hosed myself. So far, I've run these commands: $ gem update --system $ gem install arel tzinfo builder memcache-client rack rack-test rack-mount erubis mail text-format thor bundler i18n $ gem install rails --pre However, when I run the last command, I get this error: ERROR: While executing gem ... (Gem::FilePermissionError) You don't have write permissions into the /usr/bin directory. I think it wants me to run the command with sudo so that it can write over /usr/bin/rails. But if I do that, won't I be overwriting my Rails 2.3.5 executable? I don't want to do that. Instead, I'd like to keep both versions of Rails. Can anyone help? Thanks.

  • What's the best way to access Neo4j from Django?

    - by abdel
    it seems that i found something that let me confused; i've found two Neo4j to download to python, the first one is: http://pypi.python.org/pypi/neo4j-embedded and the second one is: https://svn.neo4j.org/components/neo4j.py/trunk/ what's the difference between the two? the first one seems to be big (size), so does this mean that if i use it i'll not need the neo4j community release (milestone)? when i've installed the first one, and tried to test a django example, it seems that the directory named "model" https://svn.neo4j.org/components/neo4j.py/trunk/src/main/python/neo4j/model/ is missing? so what's the difference, and who will be better to use with Django? and what about that one? http://pypi.python.org/pypi/neo4django/

  • Run a SQL Script Against MySQL using Powershell

    - by abarr
    I have a Powershell script that backs up my MySQL DB's each night using mysqldump. This all works fine but I would like to extend the script to update a reporting db (db1) from the backup of the prod db (db2). I have written the following test script but it does not work. I have a feeling the problem is the reading of the sql file to the CommandText but I am not sure how to debug. [system.reflection.assembly]::LoadWithPartialName("MySql.Data") $mysql_server = "localhost" $mysql_user = "root" $mysql_password = "password" write-host "Create coonection to db1" # Connect to MySQL database 'db1' $cn = New-Object -TypeName MySql.Data.MySqlClient.MySqlConnection $cn.ConnectionString = "SERVER=$mysql_server;DATABASE=db1;UID=$mysql_user;PWD=$mysql_password" $cn.Open() write-host "Running backup script against db1" # Run Update Script MySQL $cm = New-Object -TypeName MySql.Data.MySqlClient.MySqlCommand $sql = Get-Content C:\db2.sql $cm.Connection = $cn $cm.CommandText = $sql $cm.ExecuteReader() write-host "Closing Connection" $cn.Close() Any assistance would be appreciated. Thanks.

  • Scrum metrics for quality

    - by zachary
    What is the best way to measure QA in scrum? We have members who typically test and they are measured against how many bugs they find. If they don't find any bugs then they are considered to be doing a bad job. However, it is my understanding that the developers and quality people are considered one in the same. I would think that they should be judged against the same metrics... not different metrics then the developers who may also be doing testing work... What is the best way to handle metrics for QA and should QA people have separate metrics from developers in scrum? Any documents or links someone can point me to in regards to this?

  • Using Jquery $getJSON How do I dynamically create data for the [data] parameter after Url param?

    - by Breadtruck
    I have no problems getting the Json to work and parse the json return. I was just wondering how I could build a dynamic "whatever data is" and stick it into [data] to pass my parameters from there and not manually append them to the url. From jquery website example: $.getJSON("test.js", { name: "John", time: "2pm" }, function(json){ alert("JSON Data: " + json.users[3].name); }); I thought I could build a string ( which doesn't make sense anyway ) and drop it inside the { }, but I obviously don't understand that part. name: isn't a string and you can't put a variable in that part, so how would I dynamically put items into whatever [data] is.

  • Shallow Copy in Java

    - by Vilius
    Hello there! I already know, what a shallow copy is, but I'm not able to impliment it. Here's a short example. public class Shallow { String name; int number; public Shallow (String name, int number) { this.name = name; this.number = number; } } Test the implementation ... public class ShallowTest { public static void main (String[] args) { Shallow shallow = new Shallow("Shallow", 123); Shallow shallowClone = new Shallow(shallow); shallowClone.name = 'Peter'; shallowClone.number = 321; System.out.println(shallow.name + " - " + shallow.number); } } As I purpose, just the reference of the non primitive datatype String would be copied, so that by calling "shallowClone.name = 'Peter';" I would also change the name of "shallow". Am I right? But somehow, it just does not want to work ....

  • Regex for Searching for Text Not Preceeded By a Specific String

    - by James
    Hi, I am working on a web site with several other developers and we have had problems where people commit JavaScript code with AJAX calls that use URL's relative to the site root. An example would be /Home/Index which will not work if the site is hosted in a virtual directory. To get round the problem we use a $.url() method to convert it to a full path, e.g. $("#container").load($.url("/Home/Index")) I am trying to write a unit test that will search each JavaScript file and find places where the $.url method is not being used. The only problem is that I cannot seem to write a regex expression to do this. I have tried the following: (?!\$\.url\()"(/\w*)+" But this does not work. I cannot find a way to say that I don't want the $.url in front. Does anyone know if this is possible? Note that I need regular expressions that are compatible with .NET Thanks.

    I'm learning from this site. I tested the following with rspec, and it passed. describe "About page" do it "should have the content 'About Us'" do visit '/static_pages/about' expect(page).to have_content('About Us') end end I changed About Us to <h1>About Us</h1> to check whether it works as I expected, but the test fails even when about.html.erb has the string <h1>About Us</h1>. Could you show me how I can use html tag expression in rspec file?

  • Creating/Handling events for controls when added during runtime.

    - by AllStar11
    I am using a Repeater which contains a placeholder. The placeholder is bound to my database and each ItemTemplate contains 1-6 radiobuttons depending on what the database returns. What I need to do is somehow keep track of which one of the radiobuttons is checked for each question so I can write the user's answers to the database when they complete the test, any ideas?? <asp:Repeater ID="Repeater1" OnItemDataBound="R1_ItemDataBound" runat="server"> <ItemTemplate> <asp:PlaceHolder ID="phAnswers" runat="server"> </asp:PlaceHolder> </ItemTemplate> </asp:Repeater> Sub R1_ItemDataBound(ByVal Sender As Object, ByVal e As RepeaterItemEventArgs) Dim tempPH As PlaceHolder tempPH = e.Item.FindControl("phAnswers") For x As Integer = 0 To (t_MC.Count - 1) newRadio = New RadioButton newRadio.ID = "Answer" + x.ToString newRadio.GroupName = "Answer" + tempQuestion.ID.ToString newRadio.Text = t_MC(x).Value newRadio.Width = 800 tempPH.Controls.Add(newRadio)

  • Mod_Rewrite: Testing URL got indexed in Google - How do I create a proper 301 redirect?

    - by Jonathan Wold
    I worked on a website for which I had a "development URL" that looked something like this: www.domainname.com.php5-9.dfw1-2.websitetestlink.com/ Now, several weeks after the website launch, there is at least one page of content indexed on Google with that URL. Question: How do I redirect all requests from that test URL to reroute to the actual domain? So, for instance, I would want: www.domainname.com.php5-9.dfw1-2.websitetestlink.com/page-name To go to: www.domainname.com/page-name The website is powered by WordPress and hosted on a PHP server. I've experimented with .htaccess without much success.

I would prefer to get a pixel value without any major calculation

  • Xcode 3.2 says the version of iPhone OS isn't supported when my iPhone OS is version 3.1.3

    - by fr0man
    I just went through the whole certificate/keychain/provisioning/appID/profile/DNA test process to get my app running on my iPhone. Turns out my iPhone OS was out of date (3.0.1 I think), so I updated it. Now it says The version of iPhone OS on “Stefanie's phone” does not match any of the versions of iPhone OS supported for development with this copy of Xcode. Please restore the device to a version of the OS listed below. If necessary, the latest version of Xcode is available here. OS Installed on Stefanie's phone 3.1.3 (7E18) Xcode Supported iPhone OS Versions 3.1.2 (7D11) 3.1.1 (7C146) 3.1.1 (7C145) 3.1 (7C144) 3.0.1 (7A400) 3.0 2.2.1 2.2 2.1.1 2.1 2.0.2 (5C1) 2.0.1 (5B108) 2.0 (5A347) But I have Xcode 3.2.1, which is supposed to support iPhone OS 3.1.3. What am I doing wrong? I have a cruddy internet connection (HughesNet), so I can't upgrade the Xcode SDK without it taking literally days.

  • Faster forking of large processes on Linux ?

    - by timday
    What's the fastest, best way on modern Linux of achieving the same effect as a fork-execve combo from a large process ? My problem is that the process forking is ~500MByte big, and a simple benchmarking test achieves only about 50 forks/s from the process (c.f ~1600 forks/s from a minimally sized process) which is too slow for the intended application. Some googling turns up vfork as having being invented as the solution to this problem... but also warnings about not to use it. Modern Linux seems to have acquired related clone and posix_spawn calls; are these likely to help ? What's the modern replacement for vfork ? I'm using 64bit Debian Lenny on an i7 (the project could move to Squeeze if posix_spawn would help).

  • Ant deploy WAR file to tomcat server failure

    - by spowers
    I am having a little trouble getting my deployment task in ant to function. I have a war file that is generated as part of the build process, and I am now trying to autodeploy that to my test server. In ant I have defined a deployment task as seen below. When I try to run it I get a file not found error on the server in the catalina.out log file. Does anyone have any idea what I am doing wrong that is causing this deploy to not function? I have checked the path, and it is correct and the WAR file exists.

  • Insert A Line At The Beginning Of A File

    - by thebourneid
    I'm trying to insert/add a line 'COMMENT DUMMY' at the beginnig of a file as a first row if /PATTERN/ not found. I know how to do this with OPEN CLOSE function. Probably after reading the file it should look something like this: open F, ">", $fn or die "could not open file: $!"; ; print F "COMMENT DUMMY\n", @array; close F; But I have a need to implement this with the use of the Tie::File function and don't know how. use strict; use warnings; use Tie::File; my $fn = 'test.txt'; tie my @lines, 'Tie::File', $fn or die "could not tie file: $!"; untie @lines;

  • Intentionally get a "MySQL server has gone away" error

    - by Jonathan
    I'm trying to cope with MySQL's error MySQL server has gone away in a django env. The quick workaround was to set the global wait_timeout MySQL variable to a huge value, but in the long run this would accumulate to many open connections. I figured I'll get the wait_timeout variable and poll the server in smaller intervals. After implementing this I tried to test it but am failing to get the error. I set global wait_timeout=15 and even set global interactive_timeout=15 but the connection refuses to disappear. I'm sure I'm polling the database in larger intervals than 15sec. What could be the cause for not being able to recreate this error?

  • Selenium WebDriver works but SLOW (Java)

    - by Chris
    Code: WebDriver driver = new FirefoxDriver(); driver.get("http://www.cnn.com"); File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE); FileUtils.copyFile(scrFile, new File("c:\\test\\screenshot.png")); I am using Selenium WebDriver to take a screenshot of webpages. It runs great. However, from the time I hit run in eclipse to the time the screenshot shows up in my local drive is 7-10 seconds. Most of the latency seems to be launching Firefox. How can I speed up this process? Is there a way that I can use an already opened Firefox browser to save on opening a new one? Is this code somehow heavy? Details- Tried on CentOS box and Win7 box both using eclipse. myspeedtest.net shows 22Mbps down and 1 Mbps up.

  • Solution: Android INSTALL_FAILED_INSUFFICIENT_STORAGE error.

    - by Andrew Smith
    The INSTALL_FAILED_INSUFFICIENT_STORAGE error is the bane of every Android developer's life. It happens regardless of app size, or how much storage is available. Rebooting the target device fixes the problem briefly, but it soon comes back. There are hundreds (if not thousands) of message board posts from people asking why the problem occurs, but the folks at Google are frustratingly silent on the issue. There is a simple workaround. If your test device is running Android 2.2 or later then add the android:installLocation attribute to your application's manifest file, with the value "preferExternal". This will force the app to be installed on the device's external storage, such as a phone's SD card. For example: <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.andrewsmith.android.darkness" android:installLocation="preferExternal" This is more of a band-aid than a fix, and it may not be ideal if you want your finished app to install on the device's internal memory. But it will at least make the development process a lot less frustrating.

  • Dynamically added script causes problems

A part of the html loaded with ajax looks like this: <script type="text/javascript" src="http://maps.google.com/maps/api/js?sensor=false"></script> <script type="text/javascript"> var options = { mapTypeId : google.maps.MapTypeId.TERRAIN } alert('test'); var map = new google.maps.Map(document.getElementById('map-canvas'), options); </script> Then this is appended with contentBox.append(data); The problem is that this causes a black page in Firefox which keeps loading. In other browsers it seems that the code is not executed at all. Is there a solution for this?
