• Sanitize Content: removing markup from Amazon's content

  - by StackOverflowNewbie

  I'm using Amazon Web Service to get product descriptions of various items. The problem is that Amazon's content contains mark up that is sometimes destructive to the layout of my web page (e.g. unclosed DIVs, etc.). I want to sanitize the content I get from Amazon. My solution would be to do the following (my initial list so far): Remove unnecessary tags such as div, span, etc. while keeping tags like p, ul, ol, etc. Remove all attributes from all the tags (e.g. seems like there are style attributes in some of the tags) Remove excess white space (e.g. multiple spaces, carriage returns, new lines, tabs, etc.) Etc. Before I go off trying to build my solution, I'm wondering if anyone has a better idea (or an already existing solution). Thanks.

• How to make an ISO copy of Linux-filesystem and user files of VPS Debian based?

  - by moogeek

  Hello! I have a Debian-Based VPS on some hosting. I want to migrate from it and i need to make a full copy of all Linux-filesystem (and installed packages) + all home directory with website files. And then pack/convert it to ISO image so that to use it on cloud hostings like Amazon. The problem is that i have only ssh root access. Hosting support can't do that for me. Another part of the question - is it possible to enlarge the Linux-filesystem by not re-installing it and using the free space of home directory? Is it possible to do? I guess it is possible with rsync or something like that. Will my Mysql databes copy together with all other data? Thanks in advance!

• Working with strings in C++

  - by Elliot Bonneville

  Hi. I'm working with strings in C++. I recently came across a problem when entering strings. I'm using cin >> string; to get my string as user input. When the user enters a space into the string, the next input is automatically filled out with the remaining letters, or sometimes left blank. As the next input string is often an integer, this will result in an unpleasant bug. What's a good fix for this?

• Strange padding in Safari when using SVG images

  - by Naman Goel

  I thought I was having issues with margins but then on a closer look I found that SVGs are acting funky in Safari 6. I am building a simple Hexagon based website. Of course I used negative vertical margins to for a little overlap to 'inter-lock' the hexagons. And to save space I was using SVG images for the hexagons. It works great in chrome and firefox, but in Safari, there is a strange padding in the SVG images. I'm using simple img tags for the svg images. Everything works when I switch to PNG, but I'd prefer to stick to SVGs. Any insight? Can I perhaps delve into the SVG code and somehow fix the SVG problem in Safari? or is it some sort of bug, that I can do nothing about without browser sniffing?

• RDLC item width is dynamic and causing extra pages to be generated (image included)?

  - by Paul Mendoza

  I'm trying to format an RDLC report file in Visual Studio 2008 and I am having a formatting issue. I have a list at the bottom that contains a matrix that expands horizontally to the right. That pink box is just to visualize the problem I'm having. When the report is rendered the matrix expands and instead of filling the pink box with the matrix is pushes the space in the pink box to the right resulting in an extra page when printing the reports. One solution would be to shrink the pink box to be the size of the matrix which I've done. But then when the matrix grows the fields at the top of the report get pushed to the right by the same amount as the growth of the matrix. Can someone please let me know what they think the solution would be? Thank you!

• Is there a way to only backup a SQL 2005 database structure fully, but only the data in a certain se

  - by TheSoftwareJedi

  I have several schemas in my database, and the largest one ("large" meaning disk space consumed) is my "web" schema which is a denormalized copy of data in the operational schemas. This denormalized data is able to be reconstructed at anytime, and is merely there for extremely fast read purposes. Since the data is redundant, and VERY large - I'd like to exclude it from being backed up. I already have stored procedures that can regenerate all of the data in that schema in a couple of hours - for use in the event of a failure. I assume I can split the tables in this schema out to another data file or such (ideally even on another drive for faster reads), but is there a way to never have that data file backup, yet still in the event of a failure its structure could be restored (and other DDL stuff like procs, views, etc)? Somewhat related, can I also have these tables not do transaction logging, if I go to "Full" backup mode for the rest of the database?

• How do I find out if the variable is declared in Python?

  - by golergka

  I want to use a module as a singleton referenced in other modules. It looks something like this (that's not actually a code I'm working on, but I simplified it to throw away all unrelated stuff): main.py import singleton import printer def main(): singleton.Init(1,2) printer.Print() if __name__ == '__main__': pass singleton.py variable1 = '' variable2 = '' def Init(var1, var2) variable1 = var1 variable2 = var2 printer.py import singleton def Print() print singleton.variable1 print singleton.variable2 I expect to get output 1/2, but instead get empty space. I understand that after I imported singleton to the print.py module the variables got initialized again. So I think that I must check if they were intialized before in singleton.py: if not (variable1): variable1 = '' if not (variable2) variable2 = '' But I don't know how to do that. Or there is a better way to use singleton modules in python that I'm not aware of :)

• Programming a loopback-device consisting of several files in Linux

  - by dubbaluga

  Hej, it is relatively easy to use a file for emulating a block-device using losetup in Linux: http://www.walkernews.net/2007/07/01/create-linux-loopback-file-system-on-disk-file/ Can anyone please give me a hint on what to look for in case I want to program my own block-device which is based on several files I'm taking content from? For your understanding, I would like to let's say take bytes 1-500 and 1.000-3.000 from file1 and bytes 501-999 and bytes 3.001 to 5.000 from file2 to offer them as a combined block-device. My prefered programming language is Python and I want to write my program in user-space as much as possible. For Windows I found such an implementation. It's called FileDisk and HttpDisk and it can be found here: http://www.acc.umu.se/~bosse/ Thanks in advance and regards, Rainer

• Passing arguments to java vm from NSIS script

  - by CodeBuddy

  I'm developing my first java application using Eclipse. I've recently needed to adjust the amount of memory allocated by passing -Xmx256M to the JVM. The application is currently package up as a runnable jar and installed using the NSIS. I'm having a problem passing arguments to the jar file once its installed. What is the common practice for doing this? Here is what I'm currently doing in my nsi file: CreateShortcut "$SMPROGRAMS\$StartMenuGroup\$(^Name).lnk" "$SYSDIR\javaw.exe" "-jar -Xmx256M $INSTDIR\Foo.jar" This results in the following being created as the shortcut Target on windows: C:\WINDOWS\system32\javaw.exe -jar -Xmx256M C:\Program Files\Foo\Foo.jar Unfortunately this does not work due to the space in C:\Program Files, If I change the link created manually to include quotes all is well: C:\WINDOWS\system32\javaw.exe -jar -Xmx256M "C:\Program Files\Foo\Foo.jar"

• How to scale an Image in ImageView to keep the aspect ratio

  - by michael

  Hi, In android, I defined an ImageView's layoutWidth to be 'fill_parent' (which takes up the full width of the phone). My question is if the Image i put to ImageView is bigger than the layoutWidth, android will scale it, right? But what about the height? when android scale it, will it keeps the aspect ratio? What I find out is, there is some 'white space' at the top/bottom of the ImageView when android scales an image which is bigger than the ImageView. Is that true? If yes, how can I eliminate that white spaces? Thank you.

• XSLT string with HTML entities - How can I get it to render as HTML?

  - by Kache4

  I'm completely new to using XSL, so if there's any information that I'm neglecting to include, just let me know. I have a string in my XSLT file that I can display like this: <xsl:value-of select="@Description/> and it shows up, rendered in a browser like: <div>My text has html entities within it</div> <div>This includes quotes, like &quot;Hello World&quot; and sometimes whitespaces.&nbsp;</div> What can I do to get this string rendered as html, so that <div></div> results in newlines, &quot; gives me ", and &nbsp gives me a space? I could elaborate on things I've already tried that haven't worked, but I don't know if that's relevant.

• Redirect application's graphical output in Windows Vista/7 (with DWM)

  - by puri

  I want to create a desktop manager that takes informations of all running applications including states and screenshots to display and manipulate them in my virtual space (probably in 3D). It can be considered as another layer of abstraction on top of Windows itself. Because many native Windows Vista/7 features like Flip 3D and Live Thumbnails are able to show each window's activities in real-time e.g. video keeps playing in taskbar's thumbnail, I think DWM allows an application to redirect its output to somewhere else or some special processes are able to collect other applications' graphical outputs (maybe of child processes only). Has Microsoft released a set of public APIs to do so? If not, is it technically possible? And is it easier if I limit my scope to just .NET applications with WPF?

• How to Programmatically Identify a PI Font (a Dingbat) under OS X

  - by Glenn Howes

  There is a class of fonts called Pi fonts whose glyphs, under OS X, get mapped to the private Unicode space 0xF021-0xF0FF such that if you subtract 0xF000 from each unicode character to retrieve the 8-bit version of the character and be able to draw that character as if it were a standard Roman character. My question is how do I recognize these fonts? It's obvious the system can do so because there is a category on the Special Characters palette called "Pi Fonts" which apparently has the various such fonts installed on my system. In my case they are BookshelSymbolSeven, MSReferenceSpeciality, MT-Extras, Marlett, MonotypeSorts, Webdings, and various Wingdings. If I use the old fashioned QuickDraw routines to ask for the TextEncoding of these fonts, I get a value of 0x20000 which I do not see in the system header file TextCommon.h. Am I supposed to treat any font with a TextEncoding of 0x20000 as a Pi Font? And I'd rather not use any QuickDraw font handling routines for obvious reasons.

• Best free site/blog to put video tutorial

  - by nash

  Hi, i am planning to upload a video tutorial on a particular software technology. The size of the videos will be around 600 MB's to say 1 GB. I am putting it for free for anyone to download. Is there any site/blog where i can put it.I am planning to divide the videos in parts and zip them. Does blogger or any other cms allow me to upload to there sites and put download links? Or is buying web space the only option? I am not keen on using youtube as i clearly want the user to download by clicking on links and not watch them online. Also i was thinking of just uploading the videos on rapidshare/megaupload/mediafire... and put just links on a blogger post. Any suggestion from you guys?

• What Windows editor has CORRECT EOL whitespace handling?

  - by blueshift

  I'm looking for a Windows text editor for programming that handles EOL whitespace CORRECTLY, which for my idea of correct means: Strip all EOL whitespace on save, EXCEPT on lines that I haven't edited. This is to minimise the amount of EOL whitespace evil in my world, but not pollute SCM diff/blame with whitespace-only fixes (I have to deal with old / other people's code). I have played with TextPad, Notepad++, Kodomo Edit and Programmer's Notepad 2, and found all of them lacking. Also: I don't get along with vi, and I am unsure about Emacs on Windows. @Matti Virkkunen: I could mess with diff, but I want to fix the problem, not the symptoms. Fixing diff means all my, others, and server side diff tools need to be fixed, and doesn't fix space/noise/hash change issues in SCM. Example pet hate using that system: "update" tells me a file has changed. Diff shows no changes.

• How to center an R plot after removing axis labels

  - by ConnorG

  I'm working on visualizing a matrix in R (almost exactly like http://reference.wolfram.com/mathematica/ref/MatrixPlot.html), and I've been using image(<matrix>,axes=FALSE) to draw the picture. However, I noticed that with the y-axis turned off, the plot isn't centered--the space is still there for the axis ticks + label. I can finagle some centering with par(oma=c(0,0,0,2.5)) but this seems inefficient and error-prone (if my matrix were to change dimensions/become non-square). Is there a better way to force the graphic to center? The right hand margin is significantly smaller than the left.

• PHP regex help with preg_match_all

  - by Steve

  Hi, I am trying to refine a preg_match_all by finding the second occurrence of a period then a space: <?php $str = "East Winds 20 knots. Gusts to 25 knots. Waters a moderate chop. Slight chance of showers."; preg_match_all ('/(^)((.|\n)+?)(\.\s{2})/',$str, $matches); $dataarray=$matches[2]; foreach ($dataarray as $value) { echo $value; } ?> But it does not work: the {2} occurrence is incorrect. I have to use preg_match_all because I a scraping dynamic HTML. I want to capture this from the string: East Winds 20 knots. Gusts to 25 knots. Any ideas? Thx

• The width of a list that contains an embedded matrix grows unexpectedly

  - by Greg Lorenz

  I have a report in reporting services 2005 that includes a list with an embedded matrix and am attempting to put a border on the list, however, when I run the report in visual studio the matrix is growing past the end of the page and therefore the boarder is growing with it causing it to grow into the second page. It appears that there was supposedly a fix for this in reporting services 2000 service pack 1 but I am still experianceing the issue in 2005. The list has a details group that limits the records on a row to 4 using the following expression: =ceiling(rownumber("list1")/4), the matrix has a column group that should recycle those based on the rownumber determined by the list using the following expression: =rowNumber("list1_Details_Group") I have also attempted to put the list in a rectangle in hopes to stop the matrix from growing to no avail. How do I effectivly stop the matrix form growing past the space allowed by the list control?

I've tried Eclipse plugin for connecting to remote servers, but I'm still unable to create remote project. Any ideas? PS: Sorry for my English :) Thank you.

• jQuery: delegating clicks to elements that contain other elements

  - by Master Morality

  So i get the gist of $.delegate and I know why it's doing what it's doing, but I'm wondering if there is a work around. I have link elements that contain spans like so: <a href='#'> <span>Person Name</span> <span>Person Info</span> </a> I use the following code in jQuery for event delegation: containerElement.delegate('click','a',function(){...}); The trouble is that this only triggers when I click on white space not occupied by a span. I know it does this because delegate simply compares the event target to 'a' to check if it should fire the delegate, however I want to include the spans as well, pretty much anything inside the <a>...</a> what do?

• Is there an easy way to convert C# classes to PHP?

  - by John

  I am used to writing C# Windows application. However I have some free hosted PHP web space that I would like to make use of. I have a basic understanding of PHP but have never used it's object oriented capabilities. Is there an easy way to convert C# classes to PHP classes or is it just not possible to write a fully object oriented application in PHP? Update: There are no reliance on the .NET framework beyond the basics. The main aim would be to restructure the class properties, variable enums, etc. The PHP will be hosted on a Linux server.

• How do I execute a cmd in C#, then in the same window execute another command that follows?

  - by Ashh

  Hey Guys, Right what im trying to accomplish is a program that basically sets the active partition in 1 click, saving the effort time and skill of using cmd prompt etc. I have looked into the System.Management name space but couldn't work out how to use it :( So i have resorted to using CMD, i have got a module application written in C# and basically i want to run "DISKPART" which then starts the diskpart in the cmd window, then i want to ask it to "Select disk 0" followed by "select partition 1" finally followed by "active". Doing this in CMD yourself works fine but with an application its proved to be awkward :( What ive managed to get it to do is run DiskPart fine in one window with Process.Start, then get it to open a new window and run the next piece of code but because the new window hasnt ran the diskpart cmd it doesnt work :( Any suggestions? Thanks! Ash
