  • Websocket handshake response not forwarded from TCP to client

    - by Saharsh
    I am trying to create a websocket server. I can see the websocket client's opening handhshake. My response to it is received by the client laptop (I can see this on wireshark). So the TCP connection has been established. But the client (a chrome websocket client extension) does not receive the handshake packet. What could be a possible reason for TCP to not forward the handshake to the client or for the client to not be able to read the TCP message? Client handshake: GET HTTP/1.1 Upgrade: websocket Connection:Upgrade Cache-Control:no-cache Host:192.168.0.101 Origin:http://www.websocket.org Pragma:no-cache Sec-WebSocket-Extensions:permessage-deflate; client_max_window_bits, x-webkit-deflate-frame Sec-WebSocket-Key: qrmw/m+BoZije6h9HYKmVw== Sec-WebSocket-Version:13 Upgrade:websocket Server Response: HTTP/1.1 101 Switching Protocols Upgrade: websocket Connection: Upgrade Sec-WebSocket-Accept: jj1g5Io57m9ks8cme3jkbyo2asc= Access-Control-Allow-Origin: http://www.websocket.org Server: xyz Sec-WebSocket-Extensions: Thanks!

  • How do I restore the default applets to Gnome's notification area?

    - by gbacon
    I have a fresh install of Karmic Koala. In a botched attempt at trying to change my default window manager, I somehow removed at least three applets from the notification area: network manager (nm-applet), volume control (gnome-volume-control-applet), and the battery meter (???). Now if I logout and back in, these applets don't run, but I can start them from the command line. Because it's a fresh install, I completely removed my luser account and home directory. After recreating my account, I was frustrated to find that the applets are still missing and no obvious way to add them back. How can I restore the default configuration?

  • QotD: Eben Upton on Raspberry Pi Model B Shipping With 512MB of RAM

    - by $utils.escapeXML($entry.author)
    One of the most common suggestions we’ve heard since launch is that we should produce a more expensive “Model C” version of Raspberry Pi with extra RAM. This would be useful for people who want to use the Pi as a general-purpose computer, with multiple large applications running concurrently, and would enable some interesting embedded use cases (particularly using Java) which are slightly too heavyweight to fit comfortably in 256MB.The downside of this suggestion for us is that we’re very attached to $35 as our highest price point. With this in mind, we’re pleased to announce that from today all Model B Raspberry Pis will ship with 512MB of RAM as standard.Eben Upton, a founder and trustee of the Raspberry Pi foundation, in a blog post announcing the change.

  • Fan is spinning too fast just in Windows - software?

    - by B. Roland
    I've recently replaced my fans (CPU, GPU, and bought a CHA fan). The GPU remained the same, but I've seen it when it was spinned 2 times faster, than it usual... but it is rarely. The problem is, that the CPU fan in Windows (especially 7) spinned too much, 'cos it keeps in under 40°C, and it is spinning with 3300-3600 RPM, which is too high I think. If I swich to Ubuntu, it keeps on ~40-45°C with with 2500-2800 RPM, which is a big difference in numbers, and in noise. I'm looking for a manual fan control solution, or just reduce the Windows' multipliers of fan speed control, somehow... I was bought the new fans because of the lower noise (and it does it, but not with 3.6k RMP). Thank you!

  • Choppy, stuttery & sped-up sound after update

    - by Synesso
    My audio has always worked perfectly on this hardware and 12.04. Yesterday I received an update, including a kernel update. Today the sound is periodically stuffed. In youtube, mkv files via VLC and embedded audio in web pages (memrise.com) the sound can become stuttery, sped up or stopped mid play-back. Where can I go to find if this is a known problem, or report it if it is not? Also, can I find a log that will tell me what packages were updated on my machine yesterday?

  • google maps based desktop application

    - by dramaticlook
    I want to build a desktop application which has google maps embedded to it. This app should have a thread to read coordinate data online a usb microphone to use. This application will move the google map markers to their new locations based on the data retrieved from online connections on each refresh. As far as I know gmaps has a javascript API so the first idea in my mind was to embed this mapview into a java applet. So the application will run on a browser. Im not sure if this will work. Do you guys have any idea about this or any other advices you might have? Thanks in advance!!!

  • Is there a limit on the number of threads that can be spawned simultaneously?

    - by georgesl
    Yesterday I came across this question: How can i call robocopy within a python script to bulk copy multiple folders?, and I though it might be a good exercise for multithreading. I though of spawning as many threads as files needed to be copied, each routine having an exception handling system to prevent the whole copying process from crashing (and log -using mutex on the log file - if there was an error). My question: Is there a limit on the number of thread you can spawn almost simultaneously? If yes, what is the limiting factor? My question is focused on PC desktop, but I welcome any answer on different hardware (embedded systems, calculus clusters, etc.).

  • For a large website developed in PHP, is it necessary to have a framework?

    - by Martin
    I am wondering if it is necessary to have a framework or if it is a must-have if I plan to make a large website. Large website could mean a lot of things: in other words, multiple dynamic web pages (40-50 dynamic pages, mysql content) and a lot of visitors (+- a million hits per month). The site will be hosted in a dedicated server environment. I know that it could simplify coding for a developer team, that it includes libraries and a lot of advantages. But I just feel that I don't need that. I think that learning how it works, managing it and installing it would take more time and I could use that time to code. I write PHP the simplest way I could (with performance in mind) and I try to reuse my code/functions/classes most of the time and I make sure that if another developer joins the team, that he won't be lost in the code. I am also planning to use MemCached or another Cache for PHP. As I said, the site will be hosted in a dedicated server environment but will be entirely managed by the hosting company. I am pretty sure the control panel for me to control the basic stuff will be Cpanel. For a developer like me that only knows PHP, Javascript, HTML, CSS, MYSQL and really basic server management, I feel that it seems to complicated to have a framework. Am I wrong? Is it worth the time to learn all about it? Thank you for your opinions and suggestions.

  • game engine done, ideas missing

    - by Thoms
    I read at many places how people have this GREAT ideas but are not able to program themselves. I have quite the opposite problem. I have developed game engine, level editor, embedded Lua scripting language, I have even made wrapper for Android and it all works well. But I have no good idea about how to proceed with actual levels; I have no good ideas. The engine itself is very generic and can be used in many game concepts, but I just cannot think of anything useful. Do you have any thoughts on how to proceed? Where should I seek ideas? Who should I ask? I am sorry if this question is a duplicate.

  • Acrobat keyboard stealing in Firefox

    - by Uiy
    There are times when I open a pdf in firefox(which uses the acrobat plugin) and the "pdf" steals control of the keyboard. The arrow keys do not work in other programs. Well, If I hold them down they will then work but it becomes hard to navigate that way. It seems acrobat installs a global keyboard hook in some cases and takes control of the keyboard. This didn't start happening until recently(a few months ago). Note that it doesn't happen on all pdfs and everything returns to normal when the pdf is closed. This seems to be an issue with acrobat... maybe a setting? Anyone have any ideas what is going on?

  • JavaScript malware analysis

    - by begueradj
    I want to test websites for JavaScript malware presence . I plan to develop a Python program that sends the URL of a given website to a virtual machine where the dynamic execution of the eventual malicious JavaScript embedded in the website's page is monitored. My questions: Should my VM be Windows or Linux ? What if the malware damages my VM: is there a hint how to avoid that ? Or launch a new VM automatically instead ? If I use telnet client library to communicate with the VM: must I implement a server within the VM to deal with my queries or can I overcome this ? I am jut looing for hints, general ideas. Thank you for any help.

  • Identify what's painting the empty space in my Windows notification area?

    - by lance
    I have an "icon" in my Windows (XP, if it matters) notification area (by the clock) which renders no image, but rather an empty square space (no borders -- nothing rendered at all in the space where you'd expect an icon). Upon mousing over this space, it immediately collapses (disappears), preventing me from gathering any information about it. I'm assuming the collapse (on mouseover) indicates the process is no longer running. How can I learn what process is painting this "void" in my notification area? I don't control the workstation, so I can't control what launches when.

  • Brownfield Support for OVMSS

    - by Owen Allen
    The area of virtualization saw quite a few enhancements with version 12.2. There's one particular virtualization enhancement that can make a big difference for a lot of people: support for brownfield Oracle VM Servers for SPARC. Brownfield refers to Oracle VM Servers for SPARC that were created outside of Ops Center. In older versions of Ops Center, you couldn't really do anything with them - Ops Center could only manage OVM Servers that it created. If you had OVM Servers outside of Ops Center, you'd have to recreate them if you wanted to manage them. In 12.2, though, this problem is cleared up. You can discover and manage OVM Servers for SPARC that you created outside of Ops Center, so long as the LDom Manager is running. When you discover the control domain, all of the logical domains are automatically discovered and managed and appear under the control domain in the Asset tree. If you want to use server pools and migrate the logical domains to a different Oracle VM Server for SPARC system, you'll need to move the metadata to a shared library and use shared Fibre Channel or iSCSI LUNs for the guest domain storage and add the server to a server pool. See the Oracle VM Server for SPARC chapter for more information.

  • Installing Django on Windows

    - by Pranav
    Ever needed to install Django in a Microsoft Windows environment, here is a quick start guide to make that happen: Read through the official Django installation documentation, it might just save you a world of hut down the road. Download Python for your version of Windows. Install Python, my preference here is to put it into the Program Files folder under a folder named Python<Version> Add your chosen Python installation path into your Windows path environment variable. This is an optional step, however it allows you to just type python in the command line and have it fire up the Python interpreter. An easy way of adding it is going into Control Panel, System and into the Environment Variables section. Download Django, you can either download a compressed file or if you’re comfortable with using version control – check it out from the Django Subversion repository. Create a folder named django under your <Python installation directory>\Lib\site-packages\ folder. Using my example above that would have been C:\Program Files\Python25\Lib\site-packages\. If you chose to download the compressed file, open it and extract the contents of the django folder into your newly created folder. If you’d prefer to check it out from Subversion, the normal check out points are http://code.djangoproject.com/svn/django/trunk/ for the latest development copy or a named release which you’ll find under http://code.djangoproject.com/svn/django/tags/releases/. Done, you now have a working Django installation on Windows. At this point, it’d be pertinent to confirm that everything is working properly, which you can do by following the first Django tutorial. The tutorial will make mention of django-admin.py, which is a utility which offers some basic functionality to get you off the ground. The file is located in the bin folder under your Django installation directory. When you need to use it, you can either type in the full path to it or simply add that file path into your environment variables as well. Hope this helps!

  • What is the history of why bytes are eight bits?

    - by DarenW
    What where the historical forces at work, the tradeoffs to make, in deciding to use groups of eight bits as the fundamental unit ? There were machines, once upon a time, using other word sizes, but today for non-eight-bitness you must look to museum pieces, specialized chips for embedded applications, and DSPs. How did the byte evolve out of the chaos and creativity of the early days of computer design? I can imagine that fewer bits would be ineffective for handling enough data to make computing feasible, while too many would have lead to expensive hardware. Were other influences in play? Why did these forces balance out to eight bits? (BTW, if I could time travel, I'd go back to when the "byte" was declared to be 8 bits, and convince everyone to make it 12 bits, bribing them with some early 21st Century trinkets.)

  • Game engine lib and editor

    - by luke
    I would like to know the best way/best practice to handle the following situation. Suppose the project you are working on is split in two sub-projects: game engine lib editor gui. Now, you have a method bool Method( const MethodParams &params ) that will be called during game-level initialization. So it is a method belonging to the game engine lib. Now, the parameters of this method, passed as a reference the structure MethodParams can be decided via the editor, in the level design phase. Suppose the structure is the following: enum Enum1 { E1_VAL1, E1_VAL2, }; enum Enum2 { E2_VAL1, E2_VAL2, E2_VAL3, }; struct MethodParams { float value; Enum1 e1; Enum2 e2; // some other member } The editor should present a dialog that will let the user set the MethodParams struct. A text control for the field value. Furthermore, the editor needs to let the user set the fields e1 and e2 using, for example, two combo boxes (a combo box is a window control that has a list of choices). Obviously, every enum should be mapped to a string, so the user can make an informed selection (i have used E1_VAL1 etc.., but normally the enum would be more meaningful). One could even want to map every enum to a string more informative (E1_VAL1 to "Image union algorithm", E1_VAL2 to "Image intersection algorithm" and so on...). The editor will include all the relevant game egine lib files (.h etc...), but this mapping is not automatic and i am confused on how to handle it in a way that, if in future i add E1_VAL3 and E1_VAL4, the code change will be minimal.

  • Can't run monitor at native 1080p resolution on Windows 7

    - by Rex
    I have a 24" ViewSonic VX2453 monitor that supports 1920x1080p, connected using HDMI. However at that resolution, the desktop goes off the screen. Using the Nvidia control panel, I have to set it to a custom resolution of 1804x1014 to display correctly. The monitor has its drivers properly installed (the correct model name shows up in control panel after installing the drivers), and I'm running 64 bit Win7 Ultimate. I have a GeForce 560 Ti card, if that helps. Why does this happen?

  • Generating random tunnels

    - by IVlad
    What methods could we use to generate a random tunnel, similar to the one in this classic helicopter game? Other than that it should be smooth and allow you to navigate through it, while looking as natural as possible (not too symmetric but not overly distorted either), it should also: Most importantly - be infinite and allow me to control its thickness in time - make it narrower or wider as I see fit, when I see fit; Ideally, it should be possible to efficiently generate it with smooth curves, not rectangles as in the above game; I should be able to know in advance what its bounds are, so I can detect collisions and generate powerups inside the tunnel; Any other properties that let you have more control over it or offer optimization possibilities are welcome. Note: I'm not asking for which is best or what that game uses, which could spark extended discussion and would be subjective, I'm just asking for some methods that others know about or have used before or even think they might work. That is all, I can take it from there. Also asked on stackoverflow, where someone suggested I should ask here too. I think it fits in both places, since it's as much an algorithm question as it is a gamedev question, IMO.

  • Need old version Firefox Java plugin

    - by Bryan
    I need to use Java 1.6.0_20 for the software I'm running. I went to the Oracle website and downloaded jre1.6.0_20 and installed it on my computer, but can't seem to get Firefox to load Java. If I download directly from http://www.java.com/en/download/manual.jsp, the plugin works fine but is the wrong version, and I can't find on www.java.com anywhere to download any of the previous versions. According to the help (can't post link because of spam prevention), I need to go into the Java Control Panel and enable it for Mozilla. I've done this multiple times, but every time I go in to the control panel and check the box, click Apply and Save, as soon as I go back in the box is unchecked. Does anyone know either why the box is unchecked, or where I can download the old JRE that also is configured for Firefox?
