• Diagnosing a Memcache server with a high cache miss rate

  - by Hobozilla

  Hi Guys, What tools are available to debug a memcache server with a high miss rate (62%)? Ideally I would like to know the keys for the top cache misses, but I would just settle for seeing the keys of live get requests and working it out from there. I have tried a few web based things (phpMemcache) but it doesn't have the information I need. I also tried statsproxy-1.0 which appeared to do what I need but would not play ball. Many thanks

• Scroll modifier for mouse/trackball in windows

  - by askvictor

  I have a trackball (Logitech Trackman Marble in this case, though this could apply to any mouse or pointing device) where I would like to use one of the buttons as a middle-click when I click it, but to trigger scrolling action when I hold it down and move the ball around. I could do this quite easily in Linux by setting scroll-modifier in the X config, but the driver that comes with the trackball (Logitech) only allows one or the other. Is there any way to set this up in Windows 8?

  - by user1233963

  What I'm trying to do is set up a udev rule for my HP headphones (usb) with the aid of several tutorials out there. Created a file ( 90-local.rules ) in /etc/udev/rules.d and added the following: ACTION="add",SUBSYSTEM="usb", ATTR{vendor}=="Hewlett-Packard", RUN+="sh /home/alex/Scripts/usb.sh" The problem is nothing happens when I connect the headphones! What am I doing wrong? note: I did restart udev and the script works also, so it's not that

• What's the extra FTP port here?

  - by warl0ck

  While downloading a tar ball from gnu's FTP server, I found that other than standard 21 TCP port connection, I also seeing an extra connection: tcp 0 0 192.168.1.109:45056 208.118.235.20:21 ESTABLISHED 10956/wget tcp 0 0 192.168.1.109:56724 208.118.235.20:22259 ESTABLISHED 10956/wget What that port is used for? I checked /etc/services, only 20 and 21 should be in use, am I wrong? The command in use was wget 'ftp://ftp.gnu.org/gnu/tar/tar-1.26.tar.xz'

• Rejuvenated: Script Creates and Drops for Candidate Keys and Referencing Foreign Keys

  - by Adam Machanic

  Once upon a time it was 2004, and I wrote what I have to say was a pretty cool little script . (Yes, I know the post is dated 2006, but that's because I dropped the ball and failed to back-date the posts when I moved them over here from my prior blog space.) The impetus for creating this script was (and is) simple: Changing keys can be a painful experience. Sometimes you want to make a clustered key nonclustered, or a nonclustered key clustered. Or maybe you want to add a column to the key. Or remove...(read more)

• Incorrect colour blending when using a pixel shader with XNA

  - by MazK

  I'm using XNA 4.0 to create a 2D game and while implementing a layer tinting pixel shader I noticed that when the texture's alpha value is anything between 1 or 0 the end result is different than expected. The tinting works from selecting a colour and setting the amount of tint. This is achieved via the shader which works out first the starting colour (for each r, g, b and a) : float red = texCoord.r * vertexColour.r; and then the final tinted colour : output.r = red + (tintColour.r - red) * tintAmount; The alpha value isn't tinted and is left as : output.a = texCoord.a * vertexColour.a; The picture in the link below shows different backdrops against an energy ball object where it's outer glow hasn't blended as I would like it to. The middle two are incorrect as the second non tinted one should not show a glow against a white BG and the third should be entirely invisible. The blending function is NonPremultiplied. Why the alpha value is interfering with the final colour?

• How can I reorient the axes of an object?

  - by d3vid

  I spent some time in Unity yesterday trying to fire a sphere from a horizontal cylinder (like a ball from a cannon). I was using Vector3.forward, but the sphere kept coming out the top of the cylinder rather than the front. Someone suggested using Vector3.up instead, and sure enough it worked! The cylinder is vertical by default. So, it appears that when I rotated the cylinder by 90 degrees to lay it flat, the local axes remained the same. The relative front of the cylinder remained at the same point, so when I fired the sphere it shot out the new "top", not what looked to me like the "front". If I had happened to be facing the other way, I would have had to fire at Vector3.down instead. How can I reorient/reset the axes of an object so that they match my expectations? (And if I can't, how can I tell by looking which way an object is oriented?)

• Sound Waves Visualized with a Chladni Plate and Colored Sand [Video]

  - by Jason Fitzpatrick

  This eye catching demonstration combines a Chladni Plate, four piles of colored sand, and a rubber mallet to great effect–watch as the plate vibrates pattern after pattern into the sand. A Chladni Plate, named after physicist Ernst Chladni, is a steel plate that vibrates when rubbed with a rubber ball-style mallet. Different size balls create different frequencies and each frequency creates a different pattern in the sand placed atop the plate. Watch the video above to see how rubber balls, large and small, change the patterns.

• What is wrong with my Dot Product?

  - by Clay Ellis Murray

  I am trying to make a pong game but I wanted to use dot products to do the collisions with the paddles, however whenever I make a dot product objects it never changes much from .9 this is my code to make vectors vector = { make:function(object){ return [object.x + object.width/2,object.y + object.height/2] }, normalize:function(v){ var length = Math.sqrt(v[0] * v[0] + v[1] * v[1]) v[0] = v[0]/length v[1] = v[1]/length return v }, dot:function(v1,v2){ return v1[0] * v2[0] + v1[1] * v2[1] } } and this is where I am calculating the dot in my code vector1 = vector.normalize(vector.make(ball)) vector2 = vector.normalize(vector.make(object)) dot = vector.dot(vector1,vector2) Here is a JsFiddle of my code currently the paddles don't move. Any help would be greatly appreciated

• Advantages And Disadvantages Of Resource Serialization

  - by CPP_Person

  A good example is let's say I'm making a pong game. I have a PNG image for the ball and another PNG image for the paddles. Now which would be better, loading the PNG images with a PNG loader, or loading them in a separate program, serializing it, and de-serializing it in the game itself for use? The reason why this may be good to know is because it seems like game companies (or anyone in the long run) build all of their resources into some sort of file. For example, in the game Fallout: New Vegas the DLCs are loaded as a .ESM file, which includes everything it needs, all the game does is find it, serialize it, and it has the resources. Games like Penumbra: Black Plague take a different approch and add a folder which contains all the textures, sounds, scrips, ect that it needs, but not serialized (it does this with the game itself, and the DLC). Which is the better approch and why?

• Flash framerate reliability

  - by Tim Cooper

  I am working in Flash and a few things have been brought to my attention. Below is some code I have some questions on: addEventListener(Event.ENTER_FRAME, function(e:Event):void { if (KEY_RIGHT) { // Move character right } // Etc. }); stage.addEventListener(KeyboardEvent.KEY_DOWN, function(e:KeyboardEvent):void { // Report key which is down }); stage.addEventListener(KeyboardEvent.KEY_UP, function(e:KeyboardEvent):void { // Report key which is up }); I have the project configured so that it has a framerate of 60 FPS. The two questions I have on this are: What happens when it is unable to call that function every 1/60 of a second? Is this a way of processing events that need to be limited by time (ex: a ball which needs to travel to the right of the screen from the left in X seconds)? Or should it be done a different way?

• What is the etiquette in negotiating payment for a software development job

  - by EpsilonVector

  The reason I'm taking a general business question and localize it to software development is that I'm curious as to whether there are certain trends/etiquette/nuances that are typical to our industry. For example, I can imagine two different attitudes employers may generally have to payment negotiations: 1) we'll give you the best offer so we can't really be flexible about it because we already pretty much gave you everything we can give you, or 2) we'll give him an average offer and give in to a better one if forced to. If you try to play hard ball in the first attitude it'll probably cost you the job because you ask for more than they can give you, however if you don't insist on better payment in the second one you'll get a worse offer. In short, when applying to a typical job in our industry what are the typical attitudes from employers on the offers they give, what is the correct way to ask for a better payment, do these things differ between different types of companies (for example startups vs well entrenched companies), and how do these things differ between different kinds of applicants (graduate vs student)?

• Setting effects variables in XNA

  - by Badescu Alexandru

  Hello ! I am currently reading a book named "3D Graphics with XNA Game Studio 4.0" by Sean James and have some questions to ask : If i create a effect parameter named lets say SpecularPower and have in my effect a variable named SpecularPower , if i do something like effect.Parameters["SpecularPower"].SetValue(3) That wil change the SpecularPower variable in my effect ? And a second question, not regarding the book : If i have a spaceship and i've created a "boost" functionality that speeds up my spaceship, what effects should i implement to create the impresion oh high speed ? I was thinking of making everything except my spaceship blurry but i think there would be something missing . Any ideas ? Regards, Alex Badescu

• Powder games: how do they work?

  - by Marc Müller

  Hey guys, I recently found these two gems: http://powdertoy.co.uk/ http://dan-ball.jp/en/javagame/dust/ My question is: How are the physics with so many elements efficiently handled? Am I just severely underestimating modern computing power or is it possible to 'just' have a two-dimensional array, each cell of which describes what is placed at the according position and simulate each cell in every step. Or are there more complex things being done like summarising large areas of the same kind into a single data set and separating said set as needed? Are there any open-source games like this I could look at?
