  • Does anyone get zero-height select fields in Firefox 3.6.3?

    - by user350635
    If you open this HTML in Firefox 3.6.3 (confirmed in some earlier versions too), and click the drawStuff() link repeatedly, it doesn't render the contents of the last div consistently. Looking more closely it seems like it's rendering select fields with height=0. Any idea why this would happen? <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> <head> <title> A Page </title> <script type="text/javascript"> function drawStuff() { for (var i = 1; i <= 5; i++) { var curHtmlArr = []; for (var j = 0; j < 5; j++){ curHtmlArr.push("<select>"); curHtmlArr.push(getOptgroup()); curHtmlArr.push(getOptgroup()); curHtmlArr.push(getOptgroup()); curHtmlArr.push("<\/select>"); } var foobar = document.getElementById('elem_' + i); foobar.innerHTML = curHtmlArr.join(''); } } function getOptgroup(){ var htmlArr = []; htmlArr.push('<optgroup label="Whatever">'); for (var ii = 0; ii < 32; ii++){ htmlArr.push(' <option value="' + ii + '"> Blah ' + "<\/option>"); } htmlArr.push("<\/optgroup>"); return htmlArr.join(''); } </script> </head> <body> <table border=1 style="width:900px;" summary="A Table"> <tr> <td> <div id="elem_1"></div> </td> <td> <div id="elem_2"></div> </td> <td> <div id="elem_3"></div> </td> <td> <div id="elem_4"></div> </td> <td> <div>abc</div> <div id="elem_5"></div> </td> </tr> </table> <a href="javascript:drawStuff()"> drawStuff() </a> <script type="text/javascript"> drawStuff(); </script> </body> </html>

  • How to give position zero of spinner a prompt value?

    - by Eugene H
    The database is then transferring the data to a spinner which I want to leave position 0 blank so I can add a item to the spinner with no value making it look like a prompt.

  • Null pointer to struct which has zero size (empty)... It is a good practice?

    - by ProgramWriter
    Hi2All.. I have some null struct, for example: struct null_type { NullType& someNonVirtualMethod() { return *this; } }; And in some function i need to pass reference to this type. Reason: template <typename T1 = null_type, typename T2 = null_type, ... > class LooksLikeATupleButItsNotATuple { public: LooksLikeATupleButItsNotATuple(T1& ref1 = defParamHere, T2& ref2 = andHere..) : _ref1(ref1), _ref2(ref2), ... { } void someCompositeFunctionHere() { _ref1.someNonVirtualMethod(); _ref2.someNonVirtualMethod(); ... } private: T1& _ref1; T2& _ref2; ...; }; It is a good practice to use null reference as a default parameter?: *static_cast<NullType*>(0) It works on MSVC, but i have some doubts...

  • Slow performance on VMWare Linux server after Tomcat install

    - by Loftx
    We have a VMWare ESXi 4.1 server hosting a number of Linux and Windows guests. Recently a new Linux guest was added to this server and seemed to be performing well. Tomcat and some other applications on this server were then installed which seem to have caused the server to run really slowly without any obvious resource issues. Slow performance include: The time taken to bring up the password prompt over ssh takes a few seconds when it was previously instantaneous. The time taken to unzip a zip file which was previously a few seconds now takes around 30 seconds The time taken to compile vmware tools has increased by similar factors Both the VMWare console and monitoring commands don't report any issues with high CPU or memory usage but something is obviously slowing the server down somehow. Does anyone have any ideas what may be causing this issue and how it can be resolved? Thanks, Tom Edit As per your questions I’ve looked at some of the performance indicators on both the VM host and VM guest indicated. Firstly I tried reserving the full amount of memory (3gb) for this VM – no other machines on this server have any memory reservation. The swap in rate and swap out rate for the VM host and guest are now both zero. Balloon memory on the guest is zero and on the host is 3.5gb (total memory on the host is 12gb) The swap rate for the guest is also zero. Swap used by the host is 200mb on average. Compression and decompression rates for the host and guest are zero. Command aborts for the host are zero. Read latency is very low – maximum 10ms average 0.8ms. Write latency is higher – a few spikes to 170ms but mostly around 25ms – is this bad? Queue command latency is zero . Physical disk read latency averages 5ms but often 10ms Physical disk write latency averages 15ms but is often 20ms I hope this helps - let me know if you need any more information.

  • Greiner-Hormann clipping problem

    - by Belgin
    I have a set of planar polygons in 3D space defined by their vertices in counterclockwise order. Let's define the 'positive face' as being the face of the 3D polygon such as when observed, the vertices appear in counterclockwise order, and the 'negative face', the face which when observed, the vertices appear in clockwise order. I'm doing perspective projection of the set of polygons onto a projection polygon defined by the points in this order: (0, h, 0), (0, 0, 0), (w, 0, 0), and (w, h, 0), where w and h are strictly positive integers. The positive face of this projection polygon is oriented towards positive Z, and the camera point is somewhere at (0, 0, d), where d is a strictly negative number. In order to 'clip' the projected polygons into the projection polygon, I'm applying the Greiner-Hormann (PDF) clipping algorithm, which requires that the clipper and the to-be-clipped polygons be in the same order (i.e. clockwise or counterclockwise). My question is the following: How can I determine whether the projected face of the 3D polygon is the negative or the positive one? Meaning, how do I find out if I have to work with the vertices in normal or inverted order for the algorithm to work? I noticed that only if the 3D polygon is facing the projection polygon with its negative face, both of them are in the same order (counterclockwise), otherwise, a modification needs to be done. Here is a picture (PNG) that illustrates this. Note that the planes described by the polygon from the set and the projection polygon may not always be parallel.

  • Unity AddExplosionForce not doing anything

    - by Zero
    Recently I've started learning Unity3D. I'm working on a game as an exercise in which you control a space ship and have to dodge asteroids. If you feel like it's getting a bit too much you can hit the space bar, emitting a blast in all directions that repulses nearby asteroids. To create this blast I have the following code: public class PlayerBlastScript : MonoBehaviour { public ParticleSystem BlastEffect; // Update is called once per frame void Update () { if (Input.GetKeyUp(KeyCode.Space)) { Fire(); } } public void Fire() { ParticleEmitter effect = (ParticleEmitter) Instantiate (BlastEffect, transform.position, Quaternion.identity); effect.Emit(); Vector3 explosionPos = transform.position; Collider[] colliders = Physics.OverlapSphere(explosionPos, 25.0f); foreach(Collider hit in colliders) { if (!hit) { continue; } if (hit.rigidbody) { hit.rigidbody.AddExplosionForce(5000.0f, explosionPos, 100.0f); } } } } Even though the blast effect appears, the asteroids are not affected at all. The asteroids are all rigid bodies so what's the problem?

  • Where does jQuery fit-in with frameworks like JavaScriptMVC, BackboneJS, SproutCore and Knockout?

    - by Prisoner ZERO
    I have been happily using JQuery for the last 2 years and have been quite sucessful creating some really cool functionality with it...so I am very comfortable with it. I also beleive the future of the web will continue on the current client-side path. However... The next challenge seems to be coming in the form of various controller frameworks: KnockoutJS, BackboneJS, SproutCore, JavaScriptMVC (the list goes on). Additonally, there are some great AMD Loader tools for use like RequireJS or LabJS etc. However, jQuery now has define and then capabilities baked-in. It's getting harder-and-harder to keep track of it all... And now, my task seems to be to evaluate/decide-on a strategic-direction for using some form of either an MVC or MVVM framework client-side...but I have so many questions. Where does JQuery fit-in with the various controller-frameworks mentioned above? Is JQuery used alongside each or do some of them have their own 'JQuery-styled version' baked-in? Are tools like RequireJS still needed if you implement one of the various controller-frameworks mentioned above? Does the define and then capabilities baked-into JQuery now supercede the AMD Loader mentioned above? Which one seems most modular? (see notes below) NOTES: One thing I don't want in any future-framework is the requirement of having to take-in vast amounts of functionality that I don't use. Meaning, I would rather use a framework that is truly modular. For example, to use jQuery UI you have to take-in a lot other core libraries that you might not actually use. I will be experimenting with each one, but some REAL feedback would be great. I've seen some 'similar' questions, but none have really answered the above skew. Thanks in advance!

  • Refactoring an ERB Template to Haml

    - by Liam McLennan
    ERB is the default view templating system used by Ruby on Rails. Haml is an alternative templating system that uses whitespace to represent document structure. The example from the haml website shows the following equivalent markup: Haml ERB #profile .left.column #date= print_date #address= current_user.address .right.column #email= current_user.email #bio= current_user.bio <div id="profile"> <div class="left column"> <div id="date"><%= print_date %></div> <div id="address"><%= current_user.address %></div> </div> <div class="right column"> <div id="email"><%= current_user.email %></div> <div id="bio"><%= current_user.bio %></div> </div> </div> I like haml because it is concise and the significant whitespace makes it easy to see the structure at a glance. This post is about a ruby project but nhaml makes haml available for asp.net MVC also. The ERB Template Today I spent some time refactoring an ERB template to Haml. The template is called list.html.erb and its purpose is to render a list of tweets (twitter messages). <style> form { float: left; } </style> <h1>Tweets</h1> <table> <thead><tr><th></th><th>System</th><th>Human</th><th></th></tr></thead> <% @tweets.each do |tweet| %> <tr> <td><%= h(tweet['text']) %></td> <td><%= h(tweet['system_classification']) %></td> <td><%= h(tweet['human_classification']) %></td> <td><form action="/tweet/rate" method="post"> <%= token_tag %> <input type="submit" value="Positive"/> <input type="hidden" value="<%= tweet['id']%>" name="id" /> <input type="hidden" value="positive" name="rating" /> </form> <form action="/tweet/rate" method="post"> <%= token_tag %> <input type="submit" value="Neutral"/> <input type="hidden" value="<%= tweet['id']%>" name="id" /> <input type="hidden" value="neutral" name="rating" /> </form> <form action="/tweet/rate" method="post"> <%= token_tag %> <input type="submit" value="Negative"/> <input type="hidden" value="<%= tweet['id']%>" name="id" /> <input type="hidden" value="negative" name="rating" /> </form> </td> </tr> <% end %> </table> Haml Template: Take 1 My first step was to convert this page to a Haml template in place. Directly translating the ERB template to Haml resulted in: list.haml %style form {float: left;} %h1 Tweets %table %thead %tr %th %th System %th Human %th %tbody - @tweets.each do |tweet| %tr %td= tweet['text'] %td= tweet['system_classification'] %td= tweet['human_classification'] %td %form{ :action=>"/tweet/rate", :method=>"post"} = token_tag <input type="submit" value="Positive"/> <input type="hidden" value="positive" name="rating" /> %input{ :type=>"hidden", :value => tweet['id']} %form{ :action=>"/tweet/rate", :method=>"post"} = token_tag <input type="submit" value="Neutral"/> <input type="hidden" value="neutral" name="rating" /> %input{ :type=>"hidden", :value => tweet['id']} %form{ :action=>"/tweet/rate", :method=>"post"} = token_tag <input type="submit" value="Negative"/> <input type="hidden" value="negative" name="rating" /> %input{ :type=>"hidden", :value => tweet['id']} end I like this better already but I can go further. Haml Template: Take 2 The haml documentation says to avoid using iterators so I introduced a partial template (_tweet.haml) as the template to render a single tweet. _tweet.haml %tr %td= tweet['text'] %td= tweet['system_classification'] %td= tweet['human_classification'] %td %form{ :action=>"/tweet/rate", :method=>"post"} = token_tag <input type="submit" value="Positive"/> <input type="hidden" value="positive" name="rating" /> %input{ :type=>"hidden", :value => tweet['id']} %form{ :action=>"/tweet/rate", :method=>"post"} = token_tag <input type="submit" value="Neutral"/> <input type="hidden" value="neutral" name="rating" /> %input{ :type=>"hidden", :value => tweet['id']} %form{ :action=>"/tweet/rate", :method=>"post"} = token_tag <input type="submit" value="Negative"/> <input type="hidden" value="negative" name="rating" /> %input{ :type=>"hidden", :value => tweet['id']} and the list template is simplified to: list.haml %style form {float: left;} %h1 Tweets %table     %thead         %tr             %th             %th System             %th Human             %th     %tbody         = render(:partial => "tweet", :collection => @tweets) That is definitely an improvement, but then I noticed that _tweet.haml contains three form tags that are nearly identical.   Haml Template: Take 3 My first attempt, later aborted, was to use a helper to remove the duplication. A much better solution is to use another partial.  _rate_button.haml %form{ :action=>"/tweet/rate", :method=>"post"} = token_tag %input{ :type => "submit", :value => rate_button[:rating].capitalize } %input{ :type => "hidden", :value => rate_button[:rating], :name => 'rating' } %input{ :type => "hidden", :value => rate_button[:id], :name => 'id' } and the tweet template is now simpler: _tweet.haml %tr %td= tweet['text'] %td= tweet['system_classification'] %td= tweet['human_classification'] %td = render( :partial => 'rate_button', :object => {:rating=>'positive', :id=> tweet['id']}) = render( :partial => 'rate_button', :object => {:rating=>'neutral', :id=> tweet['id']}) = render( :partial => 'rate_button', :object => {:rating=>'negative', :id=> tweet['id']}) list.haml remains unchanged. Summary I am extremely happy with the switch. No doubt there are further improvements that I can make, but I feel like what I have now is clean and well factored.

  • Why doesn't 12.04 recognize my ATI Radeon X300SE graphics card?

    - by Nomad Zero
    So far everything including the BCM4321 card is working, however, the OEM ATI Radeon X300SE (RV370) is not recognized. When I go into system details the card comes up as unknown. When I run lspci the card shows up as: 01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI RV370 5B60 [Radeon X300 (PCIE)] 01:00.1 Display controller: Advanced Micro Devices [AMD] nee ATI RV370 [Radeon X300SE] I have attempted check Additional Drivers but the card does not show up as needing a driver. So far this is causing the system to run warmer as the processor is doing a bit of the work to run Unity and any full screen videos tend to be rather choppy. Is there an available driver that will fix my issue and what is the install method? I am not scared to run a terminal so no worries there, as long as I have instructions, I can find my way. I am running under 12.04 LTS Kernel 3.2.0-25-generic-pae

  • Keep cube spinning after fling

    - by Zero
    So I've been trying to get started with game development for Android using Unity3D. For my first project I've made a simple cube that you can spin using touch. For that I have the following code: using UnityEngine; using System.Collections; public class TouchScript : MonoBehaviour { float speed = 0.4f; bool canRotate = false; Transform cachedTransform; public bool CanRotate { get { return canRotate; } private set { canRotate = value; } } void Start () { // Make reference to transform cachedTransform = transform; } // Update is called once per frame void Update () { if (Input.touchCount > 0) { Touch touch = Input.GetTouch (0); // Switch through touch events switch (Input.GetTouch (0).phase) { case TouchPhase.Began: if (VerifyTouch (touch)) CanRotate = true; break; case TouchPhase.Moved: if (CanRotate) RotateObject (touch); break; case TouchPhase.Ended: CanRotate = false; break; } } } bool VerifyTouch (Touch touch) { Ray ray = Camera.main.ScreenPointToRay (touch.position); RaycastHit hit; // Check if there is a collider attached already, otherwise add one on the fly if (collider == null) gameObject.AddComponent (typeof(BoxCollider)); if (Physics.Raycast (ray, out hit)) { if (hit.collider.gameObject == this.gameObject) return true; } return false; } void RotateObject (Touch touch) { cachedTransform.Rotate (new Vector3 (touch.deltaPosition.y, -touch.deltaPosition.x, 0) * speed, Space.World); } } The above code works fine. However, I'm wondering how I can keep the cube spinning after the user lifts his finger. The user should be able to "fling" the cube, which would keep spinning and after a while would slowly come to a stop due to drag. Should I do this using AddForce or something? I'm really new to this stuff so I'd like it if you guys could point me in the right direction here :) .

  • Choosing a JavaScript Asynch-Loader

    - by Prisoner ZERO
    I’ve been looking at various asynchronous resource-loaders and I’m not sure which one to use yet. Where I work we have disparate group-efforts whose class-modules may use different versions of jQuery (etc). As such, nested dependencies may differ, as well. I have no control over this, so this means I need to dynamically load resources which may use alternate versions of the same library. As such, here are my requirements: Load JavaScript and CSS resource files asynchronously. Manage dependency-order and nested-dependencies across versions. Detect if a resource is already loaded. Must allow for cross-domain loading (CDN's) (optional) Allow us to unload a resource. I’ve been looking at: Curl RequireJS JavaScriptMVC LABjs I might be able to fake these requirements myself by loading versions into properly-namespaced variables & using an array to track what is already loaded...but (hopefully) someone has already invented this. So my questions are: Which ones do you use? And why? Are there others that my satisfy my requirements fully? Which do you find most eloquent and easiest to work with? And why?

    - by One Zero
    I have just installed a new copy of Ubuntu 12.04 on my laptop . i have noticed that my system is running 4x to 5x faster than normal . i have just install Vmware Desktop & centos for testing something . i have noticed that i has installed in just like less than 1 minute !! My system is booting so fast that after starting my laptop i got GUI in like 10 to 13 sec & shutting down in like 2 to 3 sec & all programs ( Firefox , Chrome , etc ) running so fast that i can see .... The only change i made after installation is cat /proc/sys/vm/swappiness 1 How do I configure swappiness? The System is Dell N 5110 i7 with 8GB of RAM So my question is that what should i look for that why my system running very fast ?

  • How does Ocaml decide precedence for user-defined operators?

    - by forefinger
    I want nice operators for complex arithmetic to make my code more readable. Ocaml has a Complex module, so I just want to add operators that call those functions. The most intuitive way for me is to make a new complex operator from all of the usual operators by appending '&' to the operator symbol. Thus +& and *& will be complex addition and multiplication. I would also like ~& to be complex conjugation. If I'm going to use these operators, I want them to associate the same way that normal arithmetic associates. Based on the following sessions, they are automatically behaving the way I want, but I would like to understand why, so that I don't get horrible bugs when I introduce more operators. My current guess is that their precedence is done by lexically sorting the operator symbols according to an ordering that is consistent with normal arithmetic precedence. But I cannot confirm this. Session one: # open Complex;; # let (+&) a b = add a b;; val ( +& ) : Complex.t -> Complex.t -> Complex.t = <fun> # let ( *&) a b = mul a b;; val ( *& ) : Complex.t -> Complex.t -> Complex.t = <fun> # one +& zero *& one +& zero *& one;; - : Complex.t = {re = 1.; im = 0.} # zero +& one *& zero +& one *& zero;; - : Complex.t = {re = 0.; im = 0.} # i +& i *& i +& i *& i *& i;; - : Complex.t = {re = -1.; im = 0.} Session two: # open Complex;; # let ( *&) a b = mul a b;; val ( *& ) : Complex.t -> Complex.t -> Complex.t = <fun> # let (+&) a b = add a b;; val ( +& ) : Complex.t -> Complex.t -> Complex.t = <fun> # one +& zero *& one +& zero *& one;; - : Complex.t = {re = 1.; im = 0.} # zero +& one *& zero +& one *& zero;; - : Complex.t = {re = 0.; im = 0.} # i +& i *& i +& i *& i *& i;; - : Complex.t = {re = -1.; im = 0.} # let (~&) a = conj a;; val ( ~& ) : Complex.t -> Complex.t = <fun> # (one +& i) *& ~& (one +& i);; - : Complex.t = {re = 2.; im = 0.}

  • Tetris Movement - Implementation

    - by James Brauman
    Hi gamedev, I'm developing a Tetris clone and working on the input at the moment. When I was prototyping, movement was triggered by releasing a directional key. However, in most Tetris games I've played the movement is a bit more complex. When a directional key is pressed, the shape moves one space in that direction. After a short interval, if the key is still held down, the shape starts moving in the direction continuously until the key is released. In the case of the down key being pressed, there is no pause between the initial movement and the subsequent continuous movement. I've come up with a solution, and it works well, but it's totally over-engineered. Hey, at least I can recognize when things are getting silly, right? :) public class TetrisMover { List registeredKeys; Dictionary continuousPressedTime; Dictionary totalPressedTime; Dictionary initialIntervals; Dictionary continousIntervals; Dictionary keyActions; Dictionary initialActionDone; KeyboardState currentKeyboardState; public TetrisMover() { *snip* } public void Update(GameTime gameTime) { currentKeyboardState = Keyboard.GetState(); foreach (Keys currentKey in registeredKeys) { if (currentKeyboardState.IsKeyUp(currentKey)) { continuousPressedTime[currentKey] = TimeSpan.Zero; totalPressedTime[currentKey] = TimeSpan.Zero; initialActionDone[currentKey] = false; } else { if (initialActionDone[currentKey] == false) { keyActions[currentKey](); initialActionDone[currentKey] = true; } totalPressedTime[currentKey] += gameTime.ElapsedGameTime; if (totalPressedTime[currentKey] = initialIntervals[currentKey]) { continuousPressedTime[currentKey] += gameTime.ElapsedGameTime; if (continuousPressedTime[currentKey] = continousIntervals[currentKey]) { keyActions[currentKey](); continuousPressedTime[currentKey] = TimeSpan.Zero; } } } } } public void RegisterKey(Keys key, TimeSpan initialInterval, TimeSpan continuousInterval, Action keyAction) { if (registeredKeys.Contains(key)) throw new InvalidOperationException( string.Format("The key %s is already registered.", key)); registeredKeys.Add(key); continuousPressedTime.Add(key, TimeSpan.Zero); totalPressedTime.Add(key, TimeSpan.Zero); initialIntervals.Add(key, initialInterval); continousIntervals.Add(key, continuousInterval); keyActions.Add(key, keyAction); initialActionDone.Add(key, false); } public void UnregisterKey(Keys key) { *snip* } } I'm updating it every frame, and this is how I'm registering keys for movement: tetrisMover.RegisterKey( Keys.Left, keyHoldStartSpecialInterval, keyHoldMovementInterval, () = { Move(Direction.Left); }); tetrisMover.RegisterKey( Keys.Right, keyHoldStartSpecialInterval, keyHoldMovementInterval, () = { Move(Direction.Right); }); tetrisMover.RegisterKey( Keys.Down, TimeSpan.Zero, keyHoldMovementInterval, () = { PerformGravity(); }); Issues that this doesn't address: If both left and right are held down, the shape moves back and forth really quick. If a directional key is held down and the turn finishes and the shape is replaced by a new one, the new one will move quickly in that direction instead of the little pause it is supposed to have. I could fix the issues, but I think it will make the solution even worse. How would you implement this?

Section 5.2.9 of the ACPI specification states that if the FIRMWARE_CONTROL is non-zero then X_FIRMWARE_CONTROL must be set to zero. ADVICE: The FADT FIRMWARE_CTRL is a 32 bit pointer that points to the physical memory address of the Firmware ACPI Control Structure (FACS). There is also an extended 64 bit version of this, the X_FIRMWARE_CTRL pointer that also can point to the FACS. Section 5.2.9 of the ACPI specification states that if the X_FIRMWARE_CTRL field contains a non zero value then the FIRMWARE_CTRL field *must* be zero. This error is also detected by the Linux kernel. If FIRMWARE_CTRL and X_FIRMWARE_CTRL are defined, then the kernel just uses the 64 bit version of the pointer. PASSED: Test 1, Table HPET passed.
