  • Why does Facebook convert PHP code to C++?

    - by user72245
    I read that Facebook started out in PHP, and then to gain speed, they now compile PHP as C++ code. If that's the case why don't they: Just program in c++? Surely there must be SOME errors/bugs when hitting a magic compiler button that ports PHP to c++ code , right? If this impressive converter works so nicely, why stick to PHP at all? Why not use something like Ruby or Python? Note -- I picked these two at random, but mostly because nearly everyone says coding in those languages is a "joy". So why not develop in a super great language and then hit the magic c++ compile button?

  • Find angle for projectile to meet target in parabolic arc

    - by TheBroodian
    I'm making a thing that launches projectiles in 2D. Its projectiles are fired with a set initial velocity, and are only affected by gravity. Assuming that its target is within range, and that there aren't any obstacles, how would my thing find the appropriate angle at which to launch its projectile (in radians)? The equation for this is found here: Wikipedia: Angle Required to Hit Coordinate Sadly, I'm not a physicist (a.k.a. can't read smart people math) and am having a hard time reading its breakdown. If not only for the sake of anybody else that might read this other than myself, would anybody be kind enough to break the equation down into baby words please?

  • How does a collison engine work?

    - by JXPheonix
    Original question: Click me How exactly does a collision engine work? This is an extremely broad question. What code keeps things bouncing against each other, what code makes the player walk into a wall instead of walk through the wall? How does the code constantly refresh the players position and objects position to keep gravity and collision working as it should? If you don't know what a collision engine is, basically it's generally used in platformer games to make the player acutally hit walls and the like. There's the 2d type and the 3d type, but they all accomplish the same thing: collision. So, what keeps a collision engine ticking?

  • Programming my first C++ program

    - by Jason H.
    I have a basic understanding of programming and I currently learning C++. I'm in the beginning phases of building my own CLI program for ubuntu. However, I have hit a few snags and I was wondering if I could get some clarification. The program I am working on is called "sat" and will be available via command line only. I have the main.cpp. However, my real question is more of a "best practices" for programming/organization. When my program "sat" is invoked I want it to take additional arguments. Here is an example: > sat task subtask I'm not sure if the task should be in its own task.cpp file for better organization or if it should be a function in the main.cpp? If the task should be in its own file how do you accept arguments in the main.cpp file and reference the other file? Any thoughts on which method is preferred and reference material to backup the reasoning?

  • How to repeat a POST request using Chrome's developer tools?

    - by Luke The Obscure
    Not sure if this is the right stack exchange to ask this, but here goes... I'm trying to wean myself off of Firebug, which has served me very well for a lot of years. One feature that seems to be missing in Chrome's dev tools is the ability to repeat an AJAX POST. In firebug I can right click on the request in the console and hit "Open in new tab" and the request is repeated exactly as it was originally sent. In Chrome, the same action just does a normal GET on the link, without any of the post data. Is there any way to repeat an AJAX POST in Chrome's dev tools?

  • LightScythe Creates Huge Light Paintings

    - by Jason Fitzpatrick
    Earlier this year we showed you how an LED POV staff could be used to visualize network data. This build takes it to another level and allows you to imprint entire words and images into photos. Gavin, a hardware hacker from Sydney, built an open-source POV (persistence of vision) staff after the Wi-Fi visualizer inspired him to begin playing with large POV builds. He built his POV staff using LED strips, wireless controllers, and a laptop to send the signals at the proper intervals to the staff. He can write words, create images, and even send Pac-Man racing across the frame. Hit up the link below to read more about his project and grab his schematics and parts lists.

  • How will the launcher/button work on a touch panel?

    - by burli
    I'm not sure if Unity has a design problem. If the Launcher is hidden you can bring it to front by moving the mouse over the home button or hit the Super Key. So far, so good. But what is on Tablet Devices with touch panel? Intuitively I would "click" in the corner to show the launcher, but a click will open the Dash. How should that work on a touch device? Do I have to "drag" my finger into the corner? Will touch devices have a "menu button"? Will there be a gesture to show the launcher?

  • Problem with keyboard and trackpad on ubuntu 12.04

    - by Cdub
    Have a really strange issue with my keyboard and trackpad after installing ubuntu 12.04. It picked up both fine with the livecd and in the install, but for quite awhile now, I find when I power my laptop up (Toshiba Satellite L775D-S7132), when I hit the login screen much of the time I won't have any keyboard or touchpad. I can plug in a usb mouse and then at least restart or shut the laptop down and then keep trying until it picks it up correctly, but it's really a pain to have to do that all the time. Are there quite a few bugs related to keyboard and trackpad issues with the new version? I really want to get this issue resolved as it's a major nuisance. Otherwise, my hardware gets picked up fine. Video, audio, wlan, usb work perfectly and I don't ever have any issues with them. What's the best way to figure out the problem? Thanks in advance, C.

  • Synaptics touchpad sensitivity. Issue?

    - by Dave
    Just installed 12.04 LTS and I experience some problems with my touchpad. Everytime I tap/double tap the touch the cursor is moving around (not static as should be) (for example if I want to close a window, I click on "x" button from touchpad, the cursor is moving and not always hit the "x" button). Touchpad buttons left click, right click are working well, but tap not. Did u guys experience the same problem? Is there something related to sensitivity? How to fix it? PS: on Ubuntu 11.10 didn't had this issue

  • Developing an AI opponent for Monopoly

    - by Bernhard Zürn
    i want to develop an AI opponent for the Board Game Monopoly. I want to implement the whole Game with Prolog (XPCE). The probability for a field on the Board being hit, can be computed with Markov Chains. I already know some "best practices" like "after 50% of the playing time it does not make sense to buy out of jail because in jail you get renting fees for your fields but you don't have to pay for other fields as long as you stay in prison". The interesting question always is: buy a streetfield ? buy houses / hotels ? how much ? so i think i would have to compute some kind of future liquidity .. does anyone know how to pack that into an algorithm or how to translate it to prolog ?

  • Drawing flaming letters in 3d on OpenGL ES 2.0

    - by Chiquis
    I am a bit confused about how to achieve this. What i want is to "draw with flames". I have achieved this with textures successfully, but now my concern is about doing this with particles to achieve the flaming effect. Am I supposed to have a Path in where i should add many particle emitters along the path that will "be emitting flames"? I understand the concept for 2d, but for 3d are the particles (that are quads) always supposed to be facing the user? Edit: Something else im worried about is the performance hit that will occur by having that many particle emitters, because there can be many letters and drawings at the same time. And each of these elements will have many particle emitters.

    This started to happen immediately after I had rebooted the first time after doing a system upgrade to 12.04 from 11.10. It first starts with a dialogue that says "System program problem detected". Then when I try to hit 'report problem' not much happens. I am led through a dialogue that always ends up the problem cannot be solved. I am running a MacBook1,1 I am aware this is not a lot of information, however I'm not sure which information I need to publish and how should I obtain it to debug this problem. Here's a screenshot!

  • What is the most serious limitation of Unity?

    - by ashes999
    Having read this heated question about Unity vs. UDK vs. ID something, I'm curious to know: what the repeatedly-hit, most crippling limitation(s) of Unity? In order to keep this question non-subjective, again, I'm talking about the top repeated offender(s) of Unity are. This is something that, as a Unity user, you really wish someone had told you about before you started using it. I have heard from someone that Unity does not deal well with version control, since it generates a lot of binary files (which are un-diffable). This, to me, is not really crippling as I work alone. Thoughts?

  • How do I install OpenStack?

    - by csgeek
    Supposedly openstack can be installed easily under Ubuntu 12.04 LTS. I've installed 32 and 64bit versions of Ubuntu Server with the same behavior. sudo tasksel check OpenStack hit Okay then I get a tasksel: aptitude failed (100) I've seen: http://www.hastexo.com/resources/docs/installing-openstack-essex-20121-ubuntu-1204-precise-pangolin and https://github.com/EmilienM/doc-openstack documentation, but I was hoping that since it was an LTS released and it was an option in tasksel that I was simply overlooking something obvious and it's just a matter of selecting the right checkbox and hitting okay. Too much wishful thinking?

  • Saving all hits to a web app

    - by bevanb
    Are there standard approaches to persisting data for every hit that a web app receives? This would be for analytics purposes (as a better alternative to log mining down the road). Seems like Redis would be a must. Is it advisable to also use a different DB server for that table, or would Redis be enough to mitigate the impact on the main DB? Also, how common is this practice? Seems like a no brainer for businesses who want to better understand their users, but I haven't read much about it.

It records instant messages, calls, file transfers, SMS, etc. and makes it easy to view using the Conversation tab. If you ever feel like getting rid of these history information, then you need to delete them.

  • Azure website that talks to third party services

    - by Andy Frank
    I have website that crawls data from many third party services when user browse to webpage. This can be really slow because I hit third party server and process returned data before showing it to user. I am hosting website on Azure (shared mode). I am thinking to improve my implementation. Here is what I am thinking... Run a service that crawls data from third party services, process it and then store it in database. when user browse to my site, my site pulls data from database and display them to user. But above solution is not clear to me. Should I have normal service or wcf service? If wcf service then should website talk to database or wcf service (that can access data from database)? If normal service then how can I deploy on Azure?
