• 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?

• Serializing array in PHP, preventing injection

  - by Cyclone

  I'm writing a PHP script which uses serialized arrays to store data. How can I prevent injection in serialization? It would be very easy to name your account: something";s:6:"access";s:5:"admin"; for a simple example. The user could then add the rest of the needed parameters somehow. Would addslashes work for this? Does the php unserialize pick up on that as being an escaped character? If so, is it possible to apply addslashes to an entire array without iterating through? Thanks for the help!

• alt-tab sort of web design

  - by sureshgl

  I am thinking of designing a web site having multiple related services. For every action of the user in a service there will be some computation going on in each of the other services. I want to display the service in action (chosen by the user) in the middle of the page in enlarged mode and rest of the services as small sized (shrunk) versions around the enlarged mode. The services which are shown in the shrunk version, should actually show what is happening in that service, at run time as if that was the chosen service. A close match to this sort of behavior I know is in Reliance BigTV, where all the small images of all the channels will be going on, and we can choose the one that we want to watch. After choosing that one image will become big and occupy the screen. Please, let me know if I can do some thing like this using css, html, ajax & php.

• Footer height based on screen size

  - by o-logn

  Hi everyone, I would like to create a footer which is relative to the content (so not fixed), but fills the rest of the screen. So for example, on my larger monitor, the footer would start in the same place, but fill up 100px (for example). On a smaller monitor, it only needs to fill up 75px. I tried using 100%, but it causes the page to be really big and the user can scroll down and fill the entire screen with the footer. Is there a way to get it to be a bit more reasonable size, so that it just about fills the bottom of the screen? My current code is this: .footer { position:relative; //can't be fixed as content might overlap if extended height:100%; width:100%; //fill the entire screen horizontally bottom:0px; margin-top:345px; //used to make sure content doesn't overlap } Thanks for any ideas

• How can I allow undefined options when parsing args with Getopt

  - by Ross Rogers

  If I have a command line like: my_script.pl -foo -WHATEVER My script knows about --foo, and I want Getopt to set variable $opt_foo, but I don't know anything about -WHATEVER. How can I tell Getopt to parse out the options that I've told it about, and then get the rest of the arguments in a string variable or a list. An example: use strict; use warnings; use Getopt::Long; my $foo; GetOptions('foo' => \$foo); print 'remaining options: ', @ARGV; Then, issuing perl getopttest.pl -foo -WHATEVER gives Unknown option: whatever remaining options:

• Ngram IDF smoothing

  - by adi92

  I am trying to use IDF scores to find interesting phrases in my pretty huge corpus of documents. I basically need something like Amazon's Statistically Improbable Phrases, i.e. phrases that distinguish a document from all the others The problem that I am running into is that some (3,4)-grams in my data which have super-high idf actually consist of component unigrams and bigrams which have really low idf.. For example, "you've never tried" has a very high idf, while each of the component unigrams have very low idf.. I need to come up with a function that can take in document frequencies of an n-gram and all its component (n-k)-grams and return a more meaningful measure of how much this phrase will distinguish the parent document from the rest. If I were dealing with probabilities, I would try interpolation or backoff models.. I am not sure what assumptions/intuitions those models leverage to perform well, and so how well they would do for IDF scores. Anybody has any better ideas?

• Javascript image change causes embeded UserControls to flicker

  - by Sam Barham

  I have a n html page being displayed in IE. It has some buttons made up of images with mouseover/mouseout events on them in JavaScript, and a bunch of embedded .Net UserControls. When the mouseover/mouseout events fire, I change the images src to something else (simple rollover effect). The problem is that the UserControls often (but not always) flicker when this happens. To be clear, the images don't flicker, and the rest of the page doesn't flicker, just the embedded controls. This page is local, not coming from a server or anything. So, any ideas? More information : I've noticed that highlighting text does it too...

• How to cancel a web service call if it's not responding

  - by drizzle

  Hi, I have a web page (.aspx) that calls a third party web service to get some data. It usually takes couple of seconds to get the response back, and then the rest of the page will load. Occasionally the call gets stuck either due to the web service is down, or internet connection, etc., the page just hang there and will not load. My questions is: 1) Is there a way to abort/cancel the web service call after a set amount of time? 2) Is it even possible to verify the status of the web service before calling it? Thanks.

• Shell script not picking up password file...

  - by BigDogsBarking

  Running the below shell script seems to ignore the password file I'm feeding it. I'm continually prompted for it. If I enter it, the rest of the script goes without a hitch, but as I'm running it via cron, I really need to get it to read from the file... Any suggestions? #!/bin/sh p=$(<password.txt) set -- $p pass_phrase=$1 destination="/var/www/d" cd /var/sl/ for FILE in *.pgp; do FILENAME=${FILE%.pgp} gpg --passphrase "$pass_phrase" --output "$destination/$FILENAME" --decrypt "$FILE" rm -f $FILE done

• Which C# 4.0 Book would you purchase, and why?

  - by Jeremy

  I'm currently looking at purchasing a few C# 4.0 books, namely: Essential C# 4.0 by Mark Michaelis or C# 4.0 Unleashed by Bart De Smet. I am aware that both books are yet to be released, but would you consider purchasing either of these books, or would you recommend another? Thanks for your time. Clarification: I'm not a .net Ninja, but I do have 8+ years experience with the framework & related languages. So I'm generally looking for in-depth books. I also train/instruct the rest of my organisation generally 6 - 12 months after each .net release. Each of the developers I train has the same or more .net experience then myself. Once again thank you all for your time. Update: Thank you everyone for your responses. I've decided to purchase both books along with Visual C# 2010 Recipes: A Problem-Solution Approach, as suggested by Waleed Al Balooshi.

• Issues using ivy

  - by Almas

  Hi, I am new bie to ivy. I am using packager resolver and that packager resolver resolves the zip file, unzip it, extracts the jar file from it in temp build file, but it stays temporarily and only the jar file which i specified as a module name gets copied to destination rest of all are ignored. Is there a way i can get all the jar files? I use preseverBuildDirectories but is there a better way to do it? Also is it possible for me to publish an artifact to svn using normal ivy? I got error while i was trying to use ivy 2.1.0 on XP using ant 1.8.0 java.illegalArguementException saying authorization failed. Is there a way i can work through ivy:publish? Is there a way i can use ivy variable in packager.xml? Thanks in advance, Almas

• JPanel: both implementing my own paintComponent() and rendering children doesn't work

  - by Paul Marshall

  I'm extending a JPanel to display a game board, and adding a JEditorPane at the bottom to hold some status text. Unfortunately, the game board renders just fine, but the JEditorPane is just a blank gray area until I highlight the text in it, when it will render whatever text is highlighted (but not the rest). If I'm understanding Swing right, it should work, because super.paintComponent(g) should render the other children (i.e., the JEditorPane). Tell me, o great stackoverflow, what bonehead mistake am I making? public GameMap extends JPanel { public GameMap() { JEditorPane statusLines = new JEditorPane("text/plain","Stuff"); this.setLayout(new BoxLayout(this,BoxLayout.PAGE_AXIS)); this.add(new Box.Filler(/*enough room to draw my game board*/)); this.add(statusLines); } public void paintComponent(Graphics g){ super.paintComponent(g); for ( all rows ){ for (all columns){ //paint one tile } } } }

• When defining a class as internal, do you define what would usually be public fields as internal?

  - by devoured elysium

  When defining a class as internal, do you define what would usually be public fields as internal? Or do you leave them as public? I have a set of classes with public/private methods that I have decided to set as internal. Now, should I change the class' modifier to internal and let the rest of the methods/properties as they are (public/private) or switch them to (internal/private)? I don't see a big point in changing it to internal, and if by some reason later I want to set them back to public it's going to give a lot of work to have to put them back to public again. Any other thoughts on this?

• How to set parameters in Python zlib module

  - by fagricipni

  I want to write a Python program that makes PNG files. My big problem is with generating the CRC and the data in the IDAT chunk. Python 2.6.4 does have a zlib module, but there are extra settings needed. The PNG specification REQUIRES the IDAT data to be compressed with zlib's deflate method with a window size of 32768 bytes, but I can't find how to set those parameters in the Python zlib module. As for the CRC for each chunk, the zlib module documentation indicates that it contains a CRC function. I believe that calling that CRC function as crc32(data,-1) will generate the CRC that I need, though if necessary I can translate the C code given in the PNG specification. Note that I can generate the rest of the PNG file and the data that is to be compressed for the IDAT chunk, I just don't know how to properly compress the image data for the IDAT chunk after implementing the initial filtering step.

• Javascript Hex String to Image

  - by Gunnar Hoffman

  Hello everyone. I'll cut right to the chase. Right now I am developing a web based application. It has a PHP REST based architecture that serves up XML documents. On many of these documents attributes are hex encoded picture strings. On the client side jQuery AJAX fetches an XML document with a picture in it. I need to display said picture in some <img> tags. However my knowledge on such methods is lacking so here I am asking for help. Goal: JavaScript String variable in hex or base64 HTML displayed image. Cross browser is required, or a hack for the ones that do not support it is fine. Thanks, Gunnar

• readobject method throws ClassNotFoundException

  - by eruina

  Hi all, I'm trying to pick up Java and wanted to test around with Java's client/server to make the client send a simple object of a self defined class(Message) over to the server. The problem was that I kept getting a ClassNotFoundException on the server side. I think the rest of the codes seem to be alright because other objects such as String can go through without problems. I had two different netbeans projects in different locations for client and server each. Each of them have their own copy of Message class under their respective packages. Message class implements Serializable. On the client side, I attempt to send a Message object through. On the server side, upon calling the readObject method, it seems to be finding Message class from the client's package instead of it's own. printStackTrace showed: "java.lang.ClassNotFoundException: client.Message" on the server side I have not even tried to cast or store the object received yet. Is there something I left out?

• How do I handle partial write completions from overlapped I/O using I/O Completion Ports

  - by Poni

  On Windows I/O completion ports, say I do this: void function() { WSASend("1111"); // A WSASend("2222"); // B WSASend("3333"); // C } If I got a "write-complete" that says 3 bytes of WSASend() A were sent, is it possible that right after that I'll get a "write-complete" that tells me that some or all of B & C were sent, or will TCP will hold them until I re-issue a WSASend() call with the rest of A's data? Or will TCP complete it automatically?

• Can I prevent RequiredFieldValidation from triggering against postbacks from a specific control.

  - by marcusstarnes

  I have a web form with a number of textbox controls which I've associated RequiredFieldValidator's with. I have a ValidationSummary control on the page to render any incomplete fields when I submit the page. However, I've just had to add an image upload facility to the same page, and have an 'Upload' button which I have posting back to perform the upload. I don't want this upload button to trigger the RequiredFieldValidators for the rest of the page though - I want this upload postback to be ignored as far as the validation goes. What's the best way to stop the RequiredFieldValidator's from firing when I submit this upload button on the page because at the moment, the upload won't occur unless I have first field out all of the other textbox controls on the page.

• How to Select Multiple Records from Multiple Tables at Once - SQL Server/C#/.NET/T-SQL

  - by peace

  I have two tables Customer and CustomerPhone. Customer usually has multiple phone numbers, so when i run select statement on customer 101, i will get multiple records due to the multiple phone numbers. As you see below all the "Phone" and "Fax" field belongs to CustomerPhone table. These are considered as two records in the CustomerPhone table whereas the rest of fields relate to Customer table which is a single record. What should i do to fill Phone and Fax field in this case? Should i run select statement on CustomerPhone first and then run select statement on Customer?

• Clojure: Avoiding stack overflow in Sieve of Erathosthene?

  - by nixx

  Here's my implementation of Sieve of Erathosthene in Clojure (based on SICP lesson on streams): (defn nats-from [n] (iterate inc n)) (defn divide? [p q] (zero? (rem q p))) (defn sieve [stream] (lazy-seq (cons (first stream) (sieve (remove #(divide? (first stream) %) (rest stream)))))) (def primes (sieve (nats-from 2))) Now, it's all OK when i take first 100 primes: (take 100 primes) But, if i try to take first 1000 primes, program breaks because of stack overflow. I'm wondering if is it possible to change somehow function sieve to become tail-recursive and, still, to preserve "streamnes" of algorithm? Any help???

• shall I move from prototype to jquery?

  - by opensas

  lastly I've been feeling like jquery is slowly becoming the defacto standard in js libraries I might be wrong!) or at least that is more active than the rest of the frameworks... for example I've been looking for a fine open source calendar like componente and found http://fullcalendar.vinsol.com/ we've been using prototype for very little things, like its selector capabilities ($ function as a shortcut for document.getElementById, mainly), executing some piece of js when the page is loaded and to issue some very simple ajax calls. so I guess the migration should be quite straight forward, but I'd like to know the pros / cons of migrating to prototype... on the other hand, I guess that having both of them together is not a good choice, specially taking into account that the migration should be quite simple... am I right? saludos sas

• How to leverage Spring Integration in a real-world JMS distributed architecture?

  - by ngeek

  For the following scenario I am looking for your advices and tips on best practices: In a distributed (mainly Java-based) system with: many (different) client applications (web-app, command-line tools, REST API) a central JMS message broker (currently in favor of using ActiveMQ) multiple stand-alone processing nodes (running on multiple remote machines, computing expensive operations of different types as specified by the JMS message payload) How would one best apply the JMS support provided by the Spring Integration framework to decouple the clients from the worker nodes? When reading through the reference documentation and some very first experiments it looks like the configuration of an JMS inbound adapter inherently require to use a subscriber, which in a decoupled scenario does not exist. Small side note: communication should happen via JMS text messages (using a JSON data structure for future extensibility).

• ASCII in Windows XP and Ubuntu Linux

  - by Mikey D

  I've made a program in MVSC++ which outputs memory contents (in ASCII). The ASCII I see in windows console seem to match what I see in various ASCII tables (smiley, diamond, club, right arrow etc). This program needs to compile under Linux (which is does), but the ASCII output looks completely different. A few symbols are the same but the rest are so different. Is there any way to change how terminal displays ASCII code? EDIT: The program executes correctly, it's just the ASCII that is being displayed differently.
