• unable to get into windows 7 or ubuntu after system file back on a dual boot system

  - by John Jiang

  I installed ubuntu on my dell xps 9000 which originally has a window 7 installed. So after I did system file back up as told by windows 7 and restarted my computer, I received the following message right after restarting in the black screen: roughly like this: ubuntu grub error, " " symbol cannot be found. I was wondering how I can get access into windows 7 and uninstall ubuntu all together. I actually had the same booting problem after system backup before and the solution was to install two extra ubuntus but I'd prefer not to do that. I'd highly appreciate any help!

• CakePHP 1.3 Plugin Shortcut Route

  - by Cake Baker

  Hi, I searched a lot around the web but I couldn't find any specific sollution to this. In CakePHP 1.3, different from 1.2, if you had a controller inside a plugin, and both had the same name, you could access through "<plugin>/<action>", and it would call the 'default' controller. But in 1.3, according to this: http://cakeqs.org/eng/questions/view/setting_up_magic_routes_for_plugins_in_cakephp_1_3 It was removed, and only the 'index' action in the default plugin controller can be accessed this way. I thought about adding extra code in my routes.php file, and loop through all the plugins in my app, making such routes for every action in the controllers named after the plugin, but it doesn't seem like it's the right thing to do... any other suggestions to make this work in 1.3? or at least some very specific code documentation of this particular change? I've already read something in the 1.3.0-RC4 annoucement, but it was not clear enough.. thanks

• Way to get VS 2008 to stop forcing indentation on namespaces?

  - by Earlz

  I've never really been a big fan of the way most editors handle namespaces. They always force you to add an extra pointless level of indentation. For instance, I have a lot of code in a page that I would much rather prefer formatted as namespace mycode{ class myclass{ void function(){ foo(); } void foo(){ bar(); } void bar(){ //code.. } } } and not something like namespace mycode{ class myclass{ void function(){ foo(); } void foo(){ bar(); } void bar(){ //code.. } } } Honestly, I don't really even like the class thing being indented most of the time because I usually only have 1 class per file. And it doesn't look as bad here, but when you get a ton of code and lot of scopes, you can easily have indentation that forces you off the screen, and plus here I just used 2-space tabs and not 4-space as is used by us. Anyway, is there some way to get Visual Studio to stop trying to indent namespaces for me like that?

• How to convert an HTML table to an array in python

  - by user345660

  I have an html document, and I want to pull the tables out of this document and return them as arrays. I'm picturing 2 functions, one that finds all the html tables in a document, and a second one that turns html tables into 2-dimensional arrays. Something like this: htmltables = get_tables(htmldocument) for table in htmltables: array=make_array(table) There's 2 catches: 1. The number tables varies day to day 2. The tables have all kinds of weird extra formatting, like bold and blink tags, randomly thrown in. Thanks!

• Empty page instead of custom tomcat error page

  - by Alexander

  My setting: Apache 2.2 + Tomcat 6.0 @ Windows 2008 R2 64bit static webpages: / servlet: /foo tomcat and apache are connected by mod_jk 404.jsp is placed in tomcat\webapps\ROOT tomcat\conf\web.xml: <error-page> <error-code>404</error-code> <location>/404.jsp</location> </error-page> apache\conf\extra\httpd-ssl.conf: JkMount /foo/* worker1 JkMount /404.jsp worker1 When I open https://...../404.jsp my custom error page is displayed. But when I open https://...../foo/nonexisting.html an empty page is displayed. If I remove the <error-page>...</error-page> code from web.xml and open https://...../foo/nonexisting.html then tomcats own 404 is displayed. Any hints?

• Windows threading: _beginthread vs _beginthreadex vs CreateThread C++

  - by Lirik

  What's a better way to start a thread? I'm trying to determine what are the advantages/disadvantages of _beginthread, _beginthreadex and CreateThread. All of these functions return a thread handle to a newly created thread, I already know that CreateThread provides a little extra information when an error occurs (it can be checked by calling GetLastError)... but what are some things I should consider when I'm using these functions? I'm working with a windows application, so cross-platform computability is already out of the question. I have gone through the msdn documentation and I just can't understand, for example, why anybody would decide to use _beginthread instead of CreateThread or vice versa. Cheers! Update: OK, thanks for all the info, I've also read in a couple of places that I can't call WaitForSingleObject() if I used _beginthread(), but if I call _endthread() in the thread shouldn't that work? What's the deal there?

• How to change line thickness in iText? (iText is Java pdf framework)

  - by drasto

  I'm drawing images to pdf using Java framework iText. I need to draw lines of specified width. There is a method setLineWidth(float width) in class PdfContentByte that should change it. However no matter what value I pass as its parameter the lines drawn are always extra thin. There is following line in javadoc of setLineWidth: The line width specifies the thickness of the line used to stroke a path and is measured in user space units. I don't know what is "space unit". Everything else in iText seems to be measured in point(around 1/72 inch). I cant find any reference to what are those "space units" and how to change them. code: to.setLineWidth(thickness); to.moveTo(x, y); to.lineTo(x + 100, y + 100);

• Best way to save complex Python data structures across program sessions (pickle, json, xml, database

  - by Malcolm

  Looking for advice on the best technique for saving complex Python data structures across program sessions. Here's a list of techniques I've come up with so far: pickle/cpickle json jsonpickle xml database (like SQLite) Pickle is the easiest and fastest technique, but my understanding is that there is no guarantee that pickle output will work across various versions of Python 2.x/3.x or across 32 and 64 bit implementations of Python. Json only works for simple data structures. Jsonpickle seems to correct this AND seems to be written to work across different versions of Python. Serializing to XML or to a database is possible, but represents extra effort since we would have to do the serialization ourselves manually. Thank you, Malcolm

• How do i deploy UAT and Development SharePoint solution on the same server ?

  - by Nikhil Vaghela

  I am working on a SharePoint 2010 Server and i have following items in my SharePoint solution Couple of web parts State Machine Work flow (which will be integrated to an Infopath form library) Infopath task edit forms Lets say this solutions is deployed to http://[SharePoint201Server]:[PortNumber-x]/ This is the only server i have (No extra server for UAT), and what ever has been done so far needs to be given for user acceptance testing (UAT). I may create one more site at http://[SharePoint201Server]:[PortNumber-y]/ for it. My problme is that how do i maintain two copies of my source code ? I will have to continue development on the same set of source code for next UAT release. I simply can not create simple copies of the source code as it will have same Assembly name and feature id, etc..As if i do so, any changes on under Development source code would affect UAT assemblies. One thing i can do is to create seperate projects for UAT and Development with different Features and Assembly names, but is not that too much of an unneccesory work ? What can be the best approach in such situation ?

• Some doubts in WPF

  - by xyz

  I am entirely new to WPF . Though I am going thru the tutorials and articles from net but I am having doubts . Some of the questions which have striked out so far are a) What is routed events and what extra thing it does server? b) What are dependency properties and it's benefits. c) How dependency properties differ from attached properties. d) Why does first bubbling happens follwed by tunneling? And what is the purpose of this? e.g. <canvas> <button canvas.left=10/> </canvas> Is it a dependency property or attached property? Thanks

• Animation with Initial Velocity

  - by abustin

  I've been trying to solve this problem for a number of days now but I must be missing something. Known Variables: vi = Initial Velocity t = Animation Duration d = Distance The function I'm trying to create: D(t) = the current distance for a given time Using this information I want to be able to create a smooth animation curve with varying velocity (ease-in/ease-out). The animation must be able ease-in from an initial velocity. The animation must be exactly t seconds and must be travel exactly d units. The curve should lean towards the average velocity with acceleration occurring at the beginning and the end portions of the curve. I'm open to extra configuration variables. The best I've been able to come up with is something that doesn't factor in the initial velocity. I'm hoping someone smarter can help me out. ;) Thank you! p.s. I'm working with an ECMAScript variant

• How do you write byte[] array using log4.net

  - by like.no.other

  Hi, I have a byte[] with some data in it, I would like to write this byte array AS-IS to the log file using log4.net. The problems that i am facing is that There are no overload for byte[] in TextWriter, so even implementing an IObjectRenderer is of no use. I dont have access to the underlying Stream object of Log4.net Also tried converting byte[] into char[] still when i write it, it adds an extra byte. Is this even possible with Log4.net. Thanx in Advance.

• RijndaelManaged Padding when data matches block size

  - by trampster

  If I use PKCS7 padding in RijndaelManaged with 16 bytes of data then I get 32 bytes of data output. It appears that for PKCS7 when the data size matches the block size it adds a whole extra block of data. If I use Zeros padding for 16 bytes of data I get out 16 bytes of data. So for Zeros padding if the data matches the block size then it doesn't pad. I have searched through the documentation and it says nothing about this difference in padding behavior. Can someone please point me to some kind of documentation which specifies what the padding behavior should be for the different padding modes when the data size matches the block size.

• Can EC2 instances be set up to come from different IP ranges?

  - by Joshua Frank

  I need to run a web crawler and I want to do it from EC2 because I want the HTTP requests to come from different IP ranges so I don't get blocked. So I thought distributing this on EC2 instances might help, but I can't find any information about what the outbound IP range will be. I don't want to go to the trouble of figuring out the extra complexity of EC2 and distributed data, only to find that all the instances use the same address block and I get blocked by the server anyway. NOTE: This isn't for a DoS attack or anything. I'm trying to harvest data for a legitimate business purpose, I'm respecting robots.txt, and I'm only making one request per second, but the host is still shutting me down. Edit: Commenter Paul Dixon suggests that the act of blocking even my modest crawl indicates that the host doesn't want me to crawl them and therefore that I shouldn't do it (even assuming I can work around the blocking). Do people agree with this?

• netbeans custom jax-ws stubs..

  - by Sam

  Hi, I am using netbeans 6.9. I have made a JAX-WS service that returns a complex type, I have also made a JAX-WS client to consume it. The JAX-WS system automaticly creates a class for the client, inferred from the WSDl spec. I want to make my own class for this using JAXB annotations, so that I can add some extra functions to it. How do I go about replacing the autogenerated file with my own one? Could I also use the same class in the service to control how it is transmitted? Thanks!

• How should the View pull on the Presenter in the MVP pattern

  - by John Leidegren

  I have a ASP.NET Web Forms application and I'm using some dynamic controls in the view which depend on stuff that the presenter exposes. Is it okay for the view in this case to pull on the presenter for that data? Is there anything I should be extra careful about when considering testability and a loosely coupled design. The page in this case has it's own page-life cycle and the presenter doesn't know about this. However, the page-life cycle dictates that somethings must occur at specific moments in the page-life cycle. This smells like trouble... Any known pit falls?

• Simulated click on "add more value" button of multi value cck field causes whole content form to sub

  - by ninja

  Hi I have a multi value cck field in my cck content type. I want to simulate click on "add another item" using jquery. which is like $('#edit-field-supp-quan-field-supp-quan-add-more').trigger('click'); but it causes whole content form to submit instead of adding extra multi value cck field. Manuall clicks are working perfectly. Can anyone tell me why behavior of manual clicks and simulated clicks are different. thanks ----Update ---- This is the code I was using:- $('#edit-field-freightamount-0-value').click(function(){ alert('hello'); $('#edit-field-supp-quan-field-supp-quan-add-more').trigger('click'); //$('.form-submit ahah-processed').trigger('click'); }); I actually intended to call this from inside some other function but I just wanted to test it before that . So i wrote this dummy function which is like if i click inside a texrfield it should simulate a click on "add more item" How do we prevent default action of click?

• Should I be so enthusiastic about Groovy?

  - by rukoche

  I'm currently working on my project which consists of front and back-end written in PHP and desktop app written in Java, and that's what the plan was before I discovered Groovy and later on Grails. Now after rewriting my desktop client and sketching some back-end functionality in Groovy I'm considering to drop PHP altogether in favor of Groovy (although I haven't played around with Grails yet.) For me it just looks like coding in Groovy is as simple as in PHP, but with lots of extra sugar and awesomeness of Java libraries. Comparing those two may sound awkward, but hey I'm an amateur ;) Finally to my question, from the looks of it most of the articles/blog posts about Groovy I can find is awfully outdated. Am I missing some reason why it's not so popular and which will crush my enthusiasm to bits? :D

• Why Switch/Case and not If/Else If?

  - by OB OB

  This question in mainly pointed at C/C++, but I guess other languages are relevant as well. I can't understand why is switch/case still being used instead of if/else if. It seems to me much like using goto's, and results in the same sort of messy code, while the same results could be acheived with if/else if's in a much more organized manner. Still, I see these blocks around quite often. A common place to find them is near a message-loop (WndProc...), whereas these are among the places when they raise the heaviest havoc: variables are shared along the entire block, even when not propriate (and can't be initialized inside it). Extra attention has to be put on not dropping break's, and so on... Personally, I avoid using them, and I wonder wether I'm missing something? Are they more efficient than if/else's? Are they carried on by tradition?

• memory available to 64bit Fedora guest under 32bit XP host running virtualbox

  - by Chris Card

  I have successfully installed a 64 bit Fedora 11 guest os using VirtualBox on a host machine (AMD64) running 32 bit Windows XP . At the moment the host machine has 2 Gb ram installed and I've allocated 1 Gb to the guest, which all works well. The host machine can hold a maximum of 4 Gb ram, so I was wondering if it's worth buying an extra 2 Gb for it. I know that 32 bit Windows XP can't use all of the 4 Gb, but can the guest os use any of the ram that the host os can't use?

• Using iterateFunc to call objective c method

  - by Matt Welch

  Using spacemanager, I need to perform an action on select bodies after each step, so I figured that defining my own C function for iterateFunc would be the way to go. Everything works great, except I'm not sure how to then call an obj c method in the same class. In other words, an obj c class contains both the c function replacing iterateFunc, and the method that needs to be called. I don't see how to tell the c function what 'self' is, such that I can call the method. As far as i can tell, there's no way to pass in any extra info to the new iterateFunc. Any ideas, or a better way to go about things?

• How do I inhibit "note C6311" in Microsoft C compiler?

  - by piCookie

  In this maximally clipped source example, the manifest constant FOOBAR is being redefined. This is deliberate, and there is extra code in the live case to make use of each definition. The pragma was added to get rid of a warning message, but then a note appeared, and I don't seem to find a way to get rid of the note. I've been able to modify this particular source to #undef between the #define, but I would like to know if there's a way to inhibit the note without requiring #undef, since there are multiple constants being handled the same way. #pragma warning( disable : 4005 ) // 'identifier' : macro redefinition #define FOOBAR FOO #define FOOBAR BAR The compiler banner and output are as follows Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 12.00.8804 for 80x86 Copyright (C) Microsoft Corp 1984-1998.
