• Google propose un scanner open-source pour aider les développeurs webs à lutter contre les attaques

  Sécurité : Google propose un scanner open-source Pour aider les développeurs webs à lutter contre les attaques XSS et les injections de code Google vient de mettre à la disposition des développeurs webs un scanner open-source qui permet de tester les applications dès les premières étapes de leurs conceptions pour détecter d'éventuelles failles de sécurité. Baptisé Skipfish, l'outil offrirait, d'après les dires de son auteur, des fonctionnalités similaires à celles de Nmap ou Nessus. Il utilise la détection dite heuristique et permet de mettre à jour les vulnérabilités aux attaques de types cross-scritping (XSS) et aux injections SDQ et XML, entre autres failles.

• Simple 3D Physics engine as a part of graduation project [on hold]

  - by Eugene Kolesnikov

  I am working on my graduation project and one part of it is to simulate the motion of a rigid body in 3D space. I can use either already written physics engine or to write it myself. It's quite an interesting challenge for me, so I would like to do it myself. I am able to use either C++ or Java for programming (prefer C++). I am using Mac OS X and Debian 7. Could you suggest any guides or tutorials how to do it, can't find it anywhere... More precisely, I need a very simple engine, without collision detection, and many other things that I do not know, I just need to calculate the forces and move my body, depending on the resultant force. If you think that this task is still very difficult or there is no such tutorial, please suggest me some good and simple engine.

• Is It bad for SEO to have internal redirected links? [closed]

  - by Jonas Lindqvist

  I have a large number of pages having similar but not identical content. Example: site.com/dream_dictionary_flying and site.com/dream_interpretation_flying. The problem is that although not being identical, they are sometimes on the edge of being duplicate content. The solution via redirect 301 in htaccess is simple and can be done in a minute, BUT, changing all existing links on the whole site from "/something" to "/something_else" would take ages, it would be thousands of manual changes taking x hundreds of hours. My question is this; is it bad for SEO to have internal links that are redirected, or rather HOW bad is it? For the human user it would not matter at all but from what I have experienced, the search engines don't like it. Is there any rule of thumb here? Please come back with your thoughts and experience on this. Thanks!

• How do I toggle sound with amixer?

  - by joschi

  Including Natty I was always able to toggle (mute/unmute) the 'Master' sound volume with the amixer sset Master toggle command that I linked to an edge binding in CompizConfig-Manager. Now after installing Oneiric the command only mutes the sound but doesn't unmute it. I even tried it in the Terminal but it also doesn't work. It changes 'Mono: Playback 68 [78%] [-14.25dB] [off]' to '...[on]' but the sound stays muted so that I have to unmute it via the 'sound-indicator' in the panel. How can I get this working again? What did change since Natty? Does anyone know the command the 'sound-indicator' uses to toggle the sound volume?

• Will a programming professional certificate from a university enhance my resume/prospect for being hired?

  - by Cliff

  Hi. I am a junior in Software Engineering. I'm planning to take up an Online Certification in web programming or .NET programming from the University of Illinois through O'Reilly (see link) to keep busy this summer. Will that help me get a great job? I've heard some say that certifications will give you a cutting edge. I've heard others say that it doesn't really matter. What do you think? Thanks so much for you advice and point of view.

• Square game map rendered as sphere

  - by Roflha

  For a hobby project of mine I have created a finite voxel world (similar to Minecraft), but as I said, mine is finite. When you reach the edge of it, you are sent to the other side. That is all working fine along with rendering the far side of the map, but I want to be able to render this grid as a sphere. Looking down from above, the world is a square. I basically want to be able to represent a portion of that square as a sphere, as if you were looking at a planet. Right now I am experimenting with taking a circular section of the map, and rendering that, but it look to flat (no curvature around the edges). My question then, is what would be the best way to add some curvature to the edges of a 2d circle to make it look like a hemisphere. However, I am not overly attached to this implementation so if somebody has some other idea for representing the square as a planet, I am all ears.

• Resolving a collision between point and moving line

  - by Conundrumer

  I am designing a 2d physics engine that uses Verlet integration for moving points (velocities mentioned below can be derived), constraints to represent moving line segments, and continuous collision detection to resolve collisions between moving points and static lines, and collisions between moving/static points and moving lines. I already know how to calculate the Time of Impact for both types of collision events, and how to resolve moving point static line collisions. However, I can't figure out how to resolve moving/static point moving line collisions. Here are the initial conditions in a point and moving line collision event. We have a line segment joined by two points, A and B. At this instant, point P is touching/colliding with line AB. These points have unit mass and some might have an initial velocity, unless point P is static. The line is massless and has no explicit rotational component, since points A and B could freely move around, extending or contracting the line as a result (which will be fixed later by the constraint solver). Collision is inelastic. What are the final velocities of the points after collision?

• Outline Shader Effect for Orthogonal Geometry in XNA

  - by Griffin

  I just recently started learning the art of shading, but I can't give an outline width to 2D, concave geometry when restrained to a single vertex/pixel shader technique (thanks to XNA). the shape I need to give an outline to has smooth, per-vertex coloring, as well as opacity. The outline, which has smooth, per-vertex coloring, variable width, and opacity cannot interfere with the original shape's colors. A pixel depth border detection algorithm won't work because pixel depth isn't a 3.0 semantic. expanding geometry / redrawing won't work because it interferes with the original shape's colors. I'm wondering if I can do something with the stencil/depth buffer outside of the shader functions since I have access to that through the graphics device. But I don't believe I'm able to manipulate actual values. How might I do this?

• Cursor freezes for 5 secs every now and then

  - by user20560

  I've installed Ubuntu 11.04 (64bit) on my new Thinkpad Edge 11 laptop from Lenovo with the following specs: Processor type AMD Athlon II Neo Processor Speed 1.8 GHz Memory Type DDR3 SDRAM RAM 2048 MB Hard Drive Type HDD Harddisk 250 GB Grafic processor ATI Mobility Radeon HD 6310 Ubuntu has found all my hardware and it works perfectly. I have one irritating problem though: From time to time (sometimes every minute, other times every hour)the cursor freezes for about 5 sec. This happens independently from the number of processes running on the laptop. It's only the cursor that freezes - I can still tab between windows and use the keyboard. I've installed GPointingDeviceSettings, activating the trackpoint, which btw works perfectly. Also I have installed the ATI Catalyst proprietary display driver. Anyone has an idea of whats wrong? Thank you in advance Best regards, Jens

• QuadTree: store only points, or regions?

  - by alekop

  I am developing a quadtree to keep track of moving objects for collision detection. Each object has a bounding shape, let's say they are all circles. (It's a 2D top-down game) I am unsure whether to store only the position of each object, or the whole bounding shape. If working with points, insertion and subdivision is easy, because objects will never span multiple nodes. On the other hand, a proximity query for an object may miss collisions, because it won't take the objects' dimensions into account. How to calculate the query region when you only have points? If working with regions, how to handle an object that spans multiple nodes? Should it be inserted in the nearest parent node that completely contains it, even if this exceeds the node's capacity? Thanks.

• Gnome shell crashing in 11.10 with 'purple haze' effect

  - by Andy

  I've just got Gnome with 11.10 up and running with my netbook and liked it so much I thought I'd get my parents old machine sorted with Ubuntu too. Unity works fine but when I try to switch to Gnome shell, I get problems. On login, the wallpaper appears as normal but then the colour bleeds out from the centre, leaving traces of it around the edge in a purple haze (yes, I do like Jimi Hendrix but I'm not making this up). When I go to applications, typing then pressing enter in the search field dumps me out so there's nothing but File / Edit / View etc in top left; starting a program seems to work but then there's only a white screen and no program window. Gnome classic works fine, from the limited use I've given it. I'm using an Asus desktop with ABIT motherboard, 2.6ghz with 1gb RAM; I've checked drivers and it says I'm up to date, Nvidia graphics. Anyone any ideas?

• Screen Scaling Problem

  - by Glenbot3000

  I think this is what it's called but I'm not quite sure tbf, aha. Yeah, so I updated packages last night like I do every night, and when I booted my computer this morning I had a problem whereby the display ran over the edge of the screen. This has been a problem for a while, but I rectified it by changing a setting on the nVidia program, however I think it has been updated to remove said feature as I can't find it anymore. I have no settings on my screen to adjust this either, so I'm sorta stuck without the ~20px around the contour of my screen. It is a problem at all available resolutions. Here's a lil' pic of my problem: https://docs.google.com/file/d/0ByPHeBI8W35GcmZYOThWZ0hGd0k/edit Edit: Probably also worth mentioning the screen was originally detected as "Laptop" in the Display setting and had many resolutions to choose from, however now it's displayed as "OEM" and only has three.

• How much time to wait to upgrade to a non LTS release?

  - by Jhonnytunes

  For LTS upgrades the recomendation is wait 3 months or first point release to is where the major bugs are fixed and the release is "stable" for production. What is the recommended amount of time to wait before upgrade to a non LTS release? Im just talking about the desktop version of course. Im asking because found this where say all release from 14.04 will be based on debian unstable: Cutting Edge: Starting with the 14.04 LTS development cycle, automatic full package import is performed from Debian unstable1 This is due to deploying ProposedMigration in the Ubuntu archive. From here.

• How to add a printer in gnome-shell

  - by artfulrobot

  I'm using Gnome Shell (although I'm not sure whether the "Printers" app is part of that or just part of Gnome). I go to "Printers" from the overview, click the + button on the bottom left, choose network and then see a message "FirewallD is not running. Network printer detection needs services mdns, ipp, ipp-client and samba-client enabled on firewall.". It's not auto detected anything. There's an Address box and a Search by Address tickbox, but neither seem to do anything. I'm frustrated because I know all the details of the printer, but have nowhere to put them in. Automation is supposed to make things easier, no? For example I know the printer is at lpd://10.67.5.3/lp1 but I can't put this in anywhere. Is there a GUI that works, or have I misunderstood how to use it?

• the window of calender is out of the screen

  - by draw

  hi, I've been using a external 21.5' monitor for my laptop of 12.1' monitor, and moved my top panel to the right and add a new panel to the bottom edge of the screen. A screenshot of the right part of my desktop is here: http://i.imgur.com/kOHwT.png As you see, The window of the calender is out of the screen. The alt+left mouse button did not work. How do you move the calender window? update: I managed to come up with a solution to get the window or panel of cal in the screen. Just remove the panel of clock and re-add it. But unfortunately, the preferences are lost. You have to reset the preferences, such as locations... but after re-adding 2 locations, the window of cal panel was just shown as the same of the previous screenshot before.

• Kinect hacked for augmented reality

• Rendering problems with Java LWJGL

  - by pangaea

  I'm new to rendering and so I don't know if I can speed up the code or that what I'm doing is bad. This is what it looks like But, if I have say 100-200 triangles everything is fine. Yet, when I get to 400 triangles it becomes very laggy. At 1,000 triangles it becomes 5fps at max. Also, when I try to close it everything becomes extremely laggy and the game breaks my computer. Is this normal? The code is here http://pastebin.com/9N6qdEbd game http://pastebin.com/fdkSrPGT mobs I haven't even adding collision detection.

• How do I clear all gnome shell notifications?

  - by user19448

  I use Jupiter as a power manager. Now I get a good number of notifications from it. I do not have problem with the fact that I get all these notifications. I do however, want to be able to clear all gnome shell notifications with a few clicks. Currently, my entire bottom edge of the screen is filled with notifications and I do not wish to clear each item one by one. So my question is, how do I clear these notifications? If this is not possible in the ui, is it possible to write an extension to do it? Where should I suggest this feature to gnome developers? Gnome forums are almost dead now, the administrator has not activated my created account since 5 days!

• Connecting 2 Vertices in 3DS Max?

  - by Reanimation

  How do you connect two vertices in 3DS Max 2013? I have two vertices which I wish to connect with a line to create an edge. (actually several) I have tried all I can think and done several Google searches but it only comes up with older versions method which say use the "connect" button... But I can't find the connect button on my version (see below) This is what my menu looks like: These are the vertices I'm trying to connect: Basically, I've edited an STL file and deleted some edges and vertices. Now I want to fill the gaps and triangulate what's left. Thanks.

• Algorithms for positioning rectangles evenly spaced with unknown connecting lines

  - by MacGyver

  I'm new to game development, but I'm trying to figure out a good algorithm for positioning rectangles (of any width and height) in a given surface area, and connecting them with any variation of lines. Two rectangles will never have more than one line connecting them. Where would I begin working on a problem like this? This is only a 2 dimensional surface. I read about graph theory, and it seems like this is a close representation of that. The rectangles would be considered a node, and the lines connecting them would be considered an edge in graph theory.
