  • possible to have a background color transition from color A to color B without repeating a pixel sti

    - by Andrew Heath
    For things like menubars and headers, a background color is nice. But a background color that gracefully transitions from say Blue to White is even nicer. I know this can be done by making a 1-pixel wide, X-pixel tall image file containing the desired fade and repeating it across the div, but does CSS have native support to just define colors and be done with it? Can any other language handle this?

  • REDUX: How to overcome an incompatibility between the ksh on Linux vs. that installed on AIX/Solaris

    - by Andrew Stein
    I have uncovered another problem in the effort that we are making to port several hundreds of ksh scripts from AIX, Solaris and HPUX to Linux. See here for the previous problem. This code: #!/bin/ksh if [ -a k* ]; then echo "Oh yeah!" else echo "No way!" fi exit 0 (when run in a directory with several files whose name starts with k) produces "Oh yeah!" when called with the AT&T ksh variants (ksh88 and ksh93). On the other hand it produces and error message followed by "No way!" on the other ksh variants (pdksh, MKS ksh and bash). Again, my question are: Is there an environment variable that will cause pdksh to behave like ksh93? Failing that: Is there an option on pdksh to get the required behavior?

  • gtk2 auto translation is choosing the wrong language

    - by Andrew Heath
    Not sure if yall can help this time, as I'm just using this particular program not coding with it... I downloaded Deluge, a free torrent app, and it requires GTK2 Runtime which I've also installed. Unfortunately, on my English WinXP with East Asian Language support Deluge sets itself to Chinese menus and has no option to alter the language. A bit of poking around on the internet suggests this is due to GTK2 selecting the wrong default language. Does anyone know how I can override this?

  • Xpath > How can I select a node based on both its attributes and content?

    - by Andrew Kirk
    Sample XML: <assignments> <assignment id="911990211" section-id="1942268885" item-count="21" sources="foo"> <options> <value name="NumRetakes">4</value> <value name="MultipleResultGrading">6</value> <value name="MaxFeedbackAttempts">-1</value> <value name="ItemTakesBeforeHint">1</value> <value name="TimeAllowed">0</value> </options> </assignment> <assignment id="1425185257" section-id="1505958877" item-count="4" sources="bar"> <options> <value name="NumRetakes">0</value> <value name="MultipleResultGrading">6</value> <value name="MaxFeedbackAttempts">3</value> <value name="ItemTakesBeforeHint">1</value> <value name="TimeAllowed">0</value> </options> </assignment> <assignments> Using XPath, I would like to select all assignments/assignment/options/value nodes where the nodes "name" attribute is "MaxFeedbackAttempts" and the nodes content is "-1". That is to say, I want to return each node that looks like: <value name="MaxFeedbackAttempts">-1</value> I can get each assignments/assignment/options/value node with the specified attribute using: //assignment/options/value[@name="MaxFeedbackAttempts"] I am just not sure how to refine this path to also limit the results based on the nodes content. Is there any way to do this using XPath?

  • WPF Standard Commands - Where's Exit?

    - by Andrew Shepherd
    I'm creating a standard menu in my WPF application. I know that I can create custom commands, but I know there are also a bunch of standard commands to bind to. For example, to open a file I should bind to ApplicationCommands.Open, to close a file I should bind to ApplicationCommands.Close. There's also a large number of EditCommands, ComponentCommands or NavigationCommands. There doesn't seem to be an "Exit" command. I would have expected there to be ApplicationCommands.Exit. What should I bind to the "Exit" menu item? To create a custom command for something this generic just seems wrong.

  • Oracle Merge Rejection Row Count

    - by Andrew
    Given an Oracle Merge statement with a rejection limit, is there a shorthand way to identify how many rows were rejected, without being forced to query the rejection destination? The rejection destination has records pre-merge, so would currently have to be counted twice and the difference taken, but it seems like there should be a counter exposed, given that it has to be aware of whether it has exceeded the rejection limit.

  • Can anyone give me a sample DSP script in C/C++

    - by Andrew
    Im working on a (Audio) DSP project and just wondering if there are any sample (Open source) DSP example that are written in c or c++, for my MSP430 Chip. I just want something as a guideline so i can program my own script using the ACD and DCA on my board for sampling. http://focus.ti.com/docs/toolsw/folders/print/msp-exp430f5438.html Thats my board, MSP430F5438 Experimenter Board, from what i herd it can run dsp script via the USB connection with the computer. Im using CCS ( From TI, code composer studio) and Octave/Matlab. Just any DSP example scripts or sites that will help me create my own would be appreciated. What im tying to do, Partial audio (sampled) track -- Nyquist rate sampling -- over- and undersampling -- reconstruction of the audio track.

  • What was "The Next Big Thing" when you were just starting out in programming?

    - by Andrew
    I'm at the beginning of my career and there are lots of things which are being touted as "The Next Big Thing". For example: Dependency Injection (Spring, etc) MVC (Struts, ASP.NET MVC) ORMs (Linq To SQL, Hibernate) Agile Software Development These things have probably been around for some time, but I've only just started out. And don't get me wrong, I think these things are great! So, what was "The Next Big Thing" when you were starting out? When was it? Were people sceptical of it at first? Why? Did you think it would catch on? Did it pan out and become widely accepted/used? If not, why not? EDIT It's been nearly a week since I first posted this question and I can safely say that I did not expect such explosive interest. I asked the question so that I could gain a perspective of what kinds of innovations in programming people thought were most important when they were starting out. At the time of writing this I have read ~95% of all answers. To answer a few questions, the "Next Big Things" I listed are ones that I am currently really excited about and that I had not really been exposed to until I started working. I'm hoping to implement some or all of these in the near future at my current workplace. To many people they are probably old news. In regards to the "is this a real question" debate, I can see that obviously hasn't been settled yet. I feel bad whenever I read a comment saying that these kinds of questions take away from the real meaning of SO. I'm not wholly convinced that it doesn't. On the other hand, I have seen a lot of comments saying what a great question it is. Anyway, I have chosen "The Internet!" as my answer to this question. I don't think (in my very humble opinion, and, it seems many SOers opinions) that many things related to programming can compare. Nowadays every business and their dog has a website which can do anything from simply supplying information to purchasing goods halfway around the world to updating your blog. And of course, all these businesses need people like us. Thanks to everyone for all the great answers!

  • Piping a bash variable into awk and storing the output

    - by Andrew Smith
    Hello, To illustrate my problem, TEST="Hi my name is John" OUTP=`echo $TEST | awk '{print $3}'` echo $OUTP What I would expect this to do is pass the $TEST variable into awk and store the 3rd word into $OUTP. Instead I get "Hi: not found", as if it is expecting the input to be a file. If I pass just a string instead of a variable, however, there is no problem. What would be the best way to approach this? Thanks all!

  • unix at command pass variable to shell script?

    - by Andrew
    Hi, I'm trying to setup a simple timer that gets started from a Rails Application. This timer should wait out its duration and then start a shell script that will start up ./script/runner and complete the initial request. I need script/runner because I need access to ActiveRecord. Here's my test lines in Rails output = `at #{(Time.now + 60).strftime("%H:%M")} < #{Rails.root}/lib/parking_timer.sh STRING_VARIABLE` return render :text => output Then my parking_timer.sh looks like this #!/bin/sh ~/PATH_TO_APP/script/runner -e development ~/PATH_TO_APP/lib/ParkingTimer.rb $1 echo "All Done" Finally, ParkingTimer.rb reads the passed variable with ARGV.each do|a| puts "Argument: #{a}" end The problem is that the Unix command "at" doesn't seem to like variables and only wants to deal with filenames. I either get one of two errors depending on how I position "s If I put quotes around the right hand side like so ... "~/PATH_TO_APP/lib/parking_timer.sh STRING_VARIABLE" I get, -bash: ~/PATH_TO_APP/lib/parking_timer.sh STRING_VARIABLE: No such file or directory I I leave the quotes out, I get, at: garbled time This is all happening on a Mac OS 10.6 box running Rails 2.3 & Ruby 1.8.6 I've already messed around w/ BackgrounDrb, and decided its a total PITA. I need to be able to cancel the job at any time before it is due.

  • How do I use jQueryUI's ui-states with JSF2's h:messages?

    - by Andrew
    It seems like it should be very simple to specify that the h:messages generated by JSF should be styled using jQueryUI's nice ui-states. But sadly I can't make it fit. It seems that the jQueryUI states require several elements (div,div,p,span) in order to make it work. So taking inspiration directly from the jQueryUI theme demo page: <!-- Highlight / Error --> <h2 class="demoHeaders">Highlight / Error</h2> <div class="ui-widget"> <div class="ui-state-highlight ui-corner-all" style="margin-top: 20px; padding: 0 .7em;"> <p><span class="ui-icon ui-icon-info" style="float: left; margin-right: .3em;"></span> <strong>Hey!</strong> Sample ui-state-highlight style.</p> </div> </div> <br/> <div class="ui-widget"> <div class="ui-state-error ui-corner-all" style="padding: 0 .7em;"> <p><span class="ui-icon ui-icon-alert" style="float: left; margin-right: .3em;"></span> <strong>Alert:</strong> Sample ui-state-error style.</p> </div> </div> and trying to jam the css class details into my h:message as best I can: <div class="ui-widget"> <h:messages globalOnly="true" errorClass="ui-state-error ui-corner-all ui-icon-alert" infoClass="ui-state-highlight ui-corner-all ui-icon-info"/> </div> I don't get the icon or sufficient padding etc but the colours make it through. So, the styles are being applied but they aren't working as intended. Any idea how I can make this work?

  • Oracle Hash Cluster Overflow Blocks

    - by Andrew
    When inserting a large number of rows into a single table hash cluster in Oracle, it will fill up the block with any values that hash to that hash-value and then start using overflow blocks. These overflow blocks are listed as chained off the main block, but I can not find detailed information on the way in which they are allocated or chained. When an overflow block is allocated for a hash value, is that block exclusively allocated to that hash value, or are the overflow blocks used as a pool and different hash values can then start using the same overflow block. How is the free space of the chain monitored - in that, as data is continued to be inserted, does it have to traverse the entire chain to find out if it has some free space in the current overflow chain, and then if it finds none, it then chooses to allocate a new block?

  • SQL Joins Excluding Data

    - by Andrew
    Say I have three tables: Fruit (Table 1) ------ Apple Orange Pear Banana Produce Store A (Table 2 - 2 columns: Fruit for sale => Price) ------------------------- Apple => 1.00 Orange => 1.50 Pear => 2.00 Produce Store B (Table 3 - 2 columns: Fruit for sale => Price) ------------------------ Apple => 1.10 Pear => 2.50 Banana => 1.00 If I would like to write a query with Column 1: the set of fruit offered at Produce Store A UNION Produce Store B, Column 2: Price of the fruit at Produce Store A (or null if that fruit is not offered), Column 3: Price of the fruit at Produce Store B (or null if that fruit is not offered), how would I go about joining the tables? I am facing a similar problem (with more complex tables), and no matter what I try, if the "fruit" is not at "produce store a" but is at "produce store b", it is excluded (since I am joining produce store a first). I have even written a subquery to generate a full list of fruits, then left join Produce Store A, but it is still eliminating the fruits not offered at A. Any Ideas?

  • Trouble with detecting gestures over ListView

    - by Andrew
    I have an Activity that contains a ViewFlipper. The ViewFlipper includes 2 layouts, both of which are essentially just ListViews. So the idea here is that I have two lists and to navigate from one to the other I would use a horizontal swipe. I have that working. However, what ever list item your finger is on when the swipe begins executing, that item will also be long-clicked. Here is the relevant code I have: public class MyActivity extends Activity implements OnItemClickListener, OnClickListener { private static final int SWIPE_MIN_DISTANCE = 120; private static final int SWIPE_MAX_OFF_PATH = 250; private static final int SWIPE_THRESHOLD_VELOCITY = 200; private GestureDetector mGestureDetector; View.OnTouchListener mGestureListener; class MyGestureDetector extends SimpleOnGestureListener { @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { try { if (Math.abs(e1.getY() - e2.getY()) > SWIPE_MAX_OFF_PATH) return false; // right to left swipe if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { if (mCurrentScreen != SCREEN_SECONDLIST) { mCurrentScreen = SCREEN_SECONDLIST; mFlipper.setInAnimation(inFromRightAnimation()); mFlipper.setOutAnimation(outToLeftAnimation()); mFlipper.showNext(); updateNavigationBar(); } } else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) { if (mCurrentScreen != SCREEN_FIRSTLIST) { mCurrentScreen = SCREEN_FIRSTLIST; mFlipper.setInAnimation(inFromLeftAnimation()); mFlipper.setOutAnimation(outToRightAnimation()); mFlipper.showPrevious(); updateNavigationBar(); } } } catch (Exception e) { // nothing } return true; } } @Override public boolean onTouchEvent(MotionEvent event) { if (mGestureDetector.onTouchEvent(event)) return true; else return false; } ViewFlipper mFlipper; private int mCurrentScreen = SCREEN_FIRSTLIST; private ListView mList1; private ListView mList2; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.layout_flipper); mFlipper = (ViewFlipper) findViewById(R.id.flipper); mGestureDetector = new GestureDetector(new MyGestureDetector()); mGestureListener = new View.OnTouchListener() { public boolean onTouch(View v, MotionEvent event) { if (mGestureDetector.onTouchEvent(event)) { return true; } return false; } }; // set up List1 screen mList1List = (ListView)findViewById(R.id.list1); mList1List.setOnItemClickListener(this); mList1List.setOnTouchListener(mGestureListener); // set up List2 screen mList2List = (ListView)findViewById(R.id.list2); mList2List.setOnItemClickListener(this); mList2List.setOnTouchListener(mGestureListener); } … } If I change the "return true;" statement from the GestureDetector to "return false;", I do not get long-clicks. Unfortunately, I get regular clicks. Does anyone know how I can get around this?

  • .net Globalization and ResourceManager

    - by Andrew Bullock
    I've got a console app and i need to globalize some of the hardcoded message strings. I've got two assemblies: MyProgram.Console (Console app) MyProgram.Core (class lib) In MyProgram.Core I've made a Language.en-GB.resx and set it as an Embedded Resource. In the resource I've created a key/value pair: "SomeKey" : "SomeValue" When I build my application I get: bin/MyProgram.Console.exe bin/MyProgram.Core.dll bin/en-BG/MyProgram.Core.resources.dll How do I address these resource key/values? Currently I'm trying this from a class within MyProgram.Core: var mgr = new ResourceManager(GetType().Assembly.GetName().Name, Assembly.GetExecutingAssembly()); mgr.GetString("SomeKey", new Culture("en-GB")); But I keep getting: System.Resources.MissingManifestResourceException: Could not find any resources appropriate for the specified culture or the neutral culture. Make sure "MyProgram.Core.resources" was correctly embedded or linked into assembly "MyProgram.Core" at compile time, or that all the satellite assemblies required are loadable and fully signed. What am I doing wrong? I've tried every combination I can think of for the baseName argument to the ResourceManagers ctor. Thanks

  • Marshal a list of objects from VB6 to C#

    - by Andrew
    I have a development which requires the passing of objects between a VB6 application and a C# class library. The objects are defined in the C# class library and are used as parameters for methods exposed by other classes in the same library. The objects all contain simple string/numeric properties and so marshaling has been relatively painless. We now have a requirement to pass an object which contains a list of other objects. If I was coding this in VB6 I might have a class containing a collection as a member variable. In C# I might have a class with a List member variable. Is it possible to construct a C# class in such a way that the VB6 application could populate this inner list and marshal it successfully? I don't have a lot of experience here but I would guess Id have to use an array of Object types.

  • Rails: translations for table's column.

    - by Andrew
    In rails application I have two models: Food and Drink. Both food and drink have a name, which has to be stored in two languages. How do I better realize translations for theese tables? First solution I realized was to replace name column with name_en and name_ru. Another solution is to encode with YAML hash like { :en => 'eng', :ru => 'rus' } and store yaml as a name. What would you recommend, assuming content is not static? Maybe there's good article?

    How does one secure the Java environment when running on a machine you don't control? What is to stop someone from creating a java agent or native JVMTI agent and dumping bytecode or re-writing classes to bypass licensing and/or other security checks? Is there any way to detect if any agents are running from Java code? From JNI? From a JVMTI agent?
