  • Should I use rel=index or rel=contents in this instance?

    - by Martin Bean
    I’m creating an MMA website. There’s the home page, there’s a fighters section whose index page lists fighters in the organisation, and then each fighter has a profile page. The URL structure is like this: / /fighters/ /fighters/john-doe My question is: on the fighter’s profile page I want to link to the fighters index page (/fighters). In my HTML page, which meta tag would be the most appropriate? <link href="/fighters/" rel="index" /> Or: <link href="/fighters/" rel="contents" /> I’m having trouble distinguishing which would be best, and whether rel="index" would be the index for the whole site or the current page/section I’m viewing?

  • Linux : le kernel 2.6.34 est stable, il introduit deux nouveaux systèmes de fichiers pour remplacer

    Mise à jour du 18/05/10 Le kernel 2.6.34 disponible en version stable Il introduit deux nouveaux systèmes de fichiers pour remplacer le ext4 et gérer la mémoire Flash Le kernel 2.6.34 est à présent disponible en version stable. Trois mois après la précédente version majeure du noyau (cf ci-avant), ce nouveau kernel propose deux nouveaux systèmes de gestion de fichiers. Le premier est issu du projet Ceph et sépare les données des méta-données. Ce système de fichier distribué peut faire penser à Lustre d'Oracle (utilisé par exemple dans les supercalculateurs). Même si Ceph, toujours assez expérimental, n'est pas aussi per...

  • Correctly indexing multiple domains with same content in Google and others

    - by AJweb
    I have a client with a dozen territorial domains, like mydomain.co.uk, mydomain.fr, mydomain.de, etc Most of these domains hold a different language of the same dynamic content (shop), but some, like co.uk and .com, have the same language and content, except for some content customized to each country/domain in the front page, contact and other pages. I am aware that we should use the canonical meta tag to mark those duplicated contents, but, we want the co.uk to be present in UK ( indexed in google.co.uk ) and the .com to be present in US and other countries, for example, or least that is the goal. Is there anything we can do to "help" google determine the geographical meaning of each domain? If we mark with canonical tag the .com and co.uk sites, do you know how google will decide which one to show on a given search?

  • Good floor planner program?

    - by torbengb
    I'm planning to have a house built. I want to draw up some sketches on the computer, so I am looking for a program that can help me do this. It doesn't have to be a professional architecture tool; in fact that would be too complicated just yet (but maybe later on, for the detailed work...?). A simpler tool would be better. Features should include such things as ability to draw and move walls (not just using simple boxes), calculate room/floor area, add windows and doors, and the like. That's why Inkscape or OOo Presentation won't do. On Windows, a friend would just download a cracked professional architecture tool but that is not what I want to do. Suggestions?

  • How can I inform search engines that the usefulness of some content on my site has a limited shelf life?

    - by Tim Post
    Let's say that I run a forum dedicated to computer hardware. Naturally, people are going to ask questions like: What is the best laptop for running [os] Or What is the best video card for under [amount] These may be perfectly fine discussions, but the content loses usefulness over time. An answer to either question asked in 2007 might still be relevant in 2008, but definitely not in 2012. Is there a way that I can tell search engines that certain pages might not give visitors what they're looking for after a certain date, and perhaps hint to a page on my site that would provide good information? Perhaps something I could set in HTTP response headers, meta tags or even a site map?

  • Collisions between moving ball and polygons

    - by miguelSantirso
    I know this is a very typical problem and that there area a lot of similar questions, but I have been looking for a while and I have not found anything that fits what I want. I am developing a 2D game in which I need to perform collisions between a ball and simple polygons. The polygons are defined as an array of vertices. I have implemented the collisions with the bounding boxes of the polygons (that was easy) and I need to refine that collision in the cases where the ball collides with the bounding box. The ball can move quite fast and the polygons are not too big so I need to perform continuous collisions. I am looking for a method that allows me to detect if the ball collides with a polygon and, at the same time, calculate the new direction for the ball after bouncing in the polygon. (I am using XNA, in case that helps)

  • Is there a good way to get pixel-perfect collision detection in XNA?

    - by ashes999
    Is there a well-known way (or perhaps reusable bit of code) for pixel-perfect collision detection in XNA? I assume this would also use polygons (boxes/triangles/circles) for a first-pass, quick-test for collisions, and if that test indicated a collision, it would then search for a per-pixel collision. This can be complicated, because we have to account for scale, rotation, and transparency. WARNING: If you're using the sample code from the link from the answer below, be aware that the scaling of the matrix is commented out for good reason. You don't need to uncomment it out to get scaling to work.

  • Unity Occlusion Portals: What and How?

    - by Nick Wiggill
    (Here I eat my words on Meta about posting Unity questions on Unity Answers... since that site is less responsive than this one.) Unity provides cell-based Occlusion Culling (via Umbra, I believe). However, a newer feature that it supports is Occlusion Portals. The question is, if BSP-based occlusion culling is already a feature of Unity, what do portals add, and how? PS. This question is not "What are portals?" -- I'm aware of the original Quake BSP-style portals -- which is partly why I find the explicit portal concept in Unity odd, since it uses BSP anyway.

  • How should I select continuous integration tool?

    - by DeveloperDon
    I found this cool comparison table for integration servers on Wikipedia, but I am a little uncertain how to rank the tools vs. my needs and interests. The chart itself seems to have a lot of boxes marked unknown, so if you are comfortable updating it on Wikipedia, that could be great too. Are there a few top performing products so I can quickly narrow down to four or five options? Which products seems to have the largest user communities and most ongoing enhancements and integration with new tools? Are the open source offerings best, or are there high quality tools that can be a great deal for a single user at home? Will use of multiple systems (primary desktop, local only home network server, personal and work notebooks, multiple virtual machines spread across all) create problems and how can they be managed?

  • Google's Opinion on Javascript Page Refresh

    - by user35306
    I was wondering if anyone knows Google's view on this. My company has a homepage that features a lot of 3rd parties on it and it needs to inform customers which ones are currently online, which aren't, and which are currently busy. Because this constantly changes, we have the homepage refresh to show the most relevant and up-to-date content to our users. I'm not using a meta refresh element in the http-equiv parameter to do this. Instead I have this js element to refresh the page: window.setTimeout("refreshPage()", 120000); I just want to know whether people think Google might consider this a violation of the content guidelines or not. Or if it's not an outright violation, then at least if Google frowns on this or not. It doesn't redirect the user to a different page or anything, just refreshes the page so that they can see the most relevant content.

  • Google webmaster Verification failed.

    - by KMC
    I have a site created by Ruby on Rails. I had verified against Google Webmaster Tool some months ago, which was successful. One day webmaster starts giving me Re-verification fails. I tried again to verify my site using Meta tags and HTML files. But I kept having "Verification failed. The connection to your server timed out." Since then, Google stop crawling my site's content - though, somehow google still crawl my PDF contents on my site.

  • How can I force the (re)discovery of PulseAudio network sound devices?

    - by Christian
    I'm using the PulseAudio feature of network sound devices (not Multicast/RTP) to play sound from my netbook on the audio equipment connected to the HTPC when at home. This creates a virtual sound device that I can then use instead of the physical built-in one. Most of the time this works just fine. Sometimes however, the virtual sound device just doesn't appear. Disconnecting from and reconnecting to the network helps sometimes but not always and it's annoying and potentially bad for existing TCP connections. So my question basically is: Is there some way to tell PulseAudio "Hey, just look again if you really can't find a network sound device."? Edit: Unloading and reloading the module-zeroconf-discover with pacmd does not help either and it doesn't appear to be an avahi problem per se since avahi-browse -t --all | grep PulseAudio shows lots of right-looking stuff, even when the devices aren't listed in pavucontrol or pacmd list-sinks. Edit 2: I'm using Ubuntu 12.04 on both boxes for all the difference it might make.

  • Perspective in Modeling

    - by drsql
    Your task, model a database that represents a suburban block.  You survey the area, and see the following houses (pictures culled from Wikipedia here ) and So you look at the houses, start modeling roofs, windows, lawn, driveway, mail boxes, porches, etc etc. You get done, and with your 30+ tables you are feeling great, right? I know I would be. “I knocked this out of the park! We can capture everything about these houses.  I…am…a…superhero database modeler,” I think, “I will get a big...(read more)

  • Canonical links for huge websites

    - by Florin
    Let's say I have 5 products that are identical but the product code, the product color specifications and the product image. The title, meta and description are identical (by the way the color is in a select form). I made 4 products link canonical to the 1 that is the master based on many factors. If the master becomes inactive or without a stock one product from the other 4 will become the new master and the rest will become canonical to it. The question is if that by becomeing master from canonical will the site suffer a penalty from Google or it will work just fine? What will Google think about this strategy?

  • Linear search vs Octree (Frustum cull)

    - by Dave
    I am wondering whether I should look into implementing an octree of some kind. I have a very simple game which consists of a 3d plane for the floor. There are multiple objects scattered around on the ground, each one has an aabb in world space. Currently I just do a loop through the list of all these objects and check if its bounding box intersects with the frustum, it works great but I am wondering if if it would be a good investment in an octree. I only have max 512 of these objects on the map and they all contain bounding boxes. I am not sure if an octree would make it faster since I have so little objects in the scene.

  • SEO blog Indexing: wordpress.com subdomain vs a registered domain?

    - by rumspringa00
    I've used WordPress for a few of my client's sites, mostly small businesses and eCommerce sites. I have found through Google Analytics as well as the All in One Webmaster plugin that when it comes to social media, using WordPress is a surefire way of getting your site indexed by Google and occasionally Bing and Yahoo. Since I am a heavy WP user, I'd like to contribute by registering a dot WordPress domain for my portfolio. When using a WP installation concurrently with a WP domain, e.g. myportfolio.wordpress.com, will the site be more or less likely to be indexed rather a generic myportfolio.com domain? I've seen mixed opinions where people seem to favor a WP domain for URL output where others say that it's a moot point, and that Google will not favor a WP domain over a dot com domain as long as your meta tags are updated and content is keyword optimized. I tend to disagree and believe a WP domain would more likely be indexed and output more URLs over an individual, laconic domain like myportfolio.com. Am I wrong?

  • No windows whatsoever after compiz reset

    - by Shashank Singh
    Currently using 12.04. This time I was trying to use the application switcher, and it asked me to resolve a few conflicts most of which were not easy to comprehend. So after some yes and no dialogue boxes leading me nowhere, I thought a reset should set things fine. However, after preferences-reset to default, I can't see any window!! NONE whatsoever except the log out one when I press ctrl+alt+del All I can see is the wallpaper and the mouse pointer. I cant even see the terminal or anything when I press alt+f2. I am posting this when I switch to ubuntu 2d (I cant make out the difference between the two, but this just works for now almost the same way)

  • How important is a single-player mode in a 2-player game?

    - by Davy8
    So say you have a 2 player game, taking Chess as an example (except it's an original game with no ready-to-go AI available). Let's say there's also a social-aspect to the meta-game, so let's say it's a Chess game on Facebook where you can challenge your friends. How important is it to have a single-player mode, knowing that an AI will need to be created (I've done minimax AI for tic tac toe, but nothing too sophisticated)? Is it important enough that it should be in the initial launch of the game? Can it wait for a future iteration (knowing that being hosted on the web means the game can be updated at any time)?

  • Android, OpenGL and extending GLSurfaceView?

    - by Spoon Thumb
    This question is part-technical, part-meta, part-subjective and very specific: I'm an indie game dev working on android, and for the past 6 months I've struggled and finally succeeded in making my own 3D game app for android. So I thought I'd hop on SO and help out others struggling with android and openGL-ES However, the vast majority of questions relate to extending GLSurfaceView. I made my whole app without extending GLSurfaceView (and it runs fine). I can't see any reason at all to extend GLSurfaceView for the majority of questions I come across. Worse, the android documentation implies that you ought to, but gives no detailed explaination of why or what the pros/cons are vs not extending and doing everything through implementing your own GLSurfaceView.Renderer as I did Still, the sheer volume of questions where the problem is purely to do with extending GLSurfaceView is making me wonder whether actually there is some really good reason for doing it that way vs the way I've been doing it (and suggesting in my answers to others to do). So, is there something I'm missing? Should I stop answering questions in the meantime? Android openGL documentation

  • MVC helper functions business logic

    - by Menelaos Vergis
    I am creating some helper functions (mvc.net) for creating common controls that I need in almost every project such as alert boxes, dialogs etc. If these do not contain any business logic and it's just client side code (html, js) then it's ok. My problem arises when I need some business logic behind this helper. I want to create a 'rate my (web) application' control that will be visible every 3 days and the user may hide it for now, navigate to rate link or hide it for ever. To do this I need some sort of database access and a code that acts as business logic. Normally I would use a controller for this, with my DI and everything, but I don't know where to put this code now. This should be placed in the helper function or in a controller that responds objects instead of ActionResults?

  • My First robots.txt

    - by Whitechapel
    I'm creating my first robots.txt and wanted to get a second opinion on it. Basically I have a FTP setup on my board for some special users to transfer files between each other and I do NOT want that included in the search by the bots. I also want to point to my sitemap which gets auto generated by a PHP page. So here is what I have, what else should I include, and if I need to fix anything with it? Also, it's linking to xmlsitemap.php because that generates the sitemap when called. My goal is to allow any search bot crawl the forums to grab meta data. User-agent: * Disallow: /admin/ Disallow: /ali/ Disallow: /benny/ Disallow: /cgi-bin/ Disallow: /ders/ Disallow: /empire/ Disallow: /komodo_117/ Disallow: /xanxan/ Disallow: /zeroordie/ Disallow: /tmp/ Sitemap: http://www.vivalanation.com/forums/xmlsitemap.php Edit, I'm not sure how to handle all the user's folders under /public_html/ since the robots.txt will be going in /public_html.

  • SEO: disallowing Google from indexing forms in iframes or not?

    - by Marco Demaio
    I usually place forms in iframes (i.e. order form, request assistance form, contact forms, ect.). Just the forms, I never place other contents or pages in iframes. From a SEO point of view, would you exclude forms from being indexed/crawled by Google or not? I mean my forms hardly ever contains keyword/keyphrases, moreover I obviously place empty title/meta description tags in pages shown in iframe to display forms, cause those titles are never displaied in browser title bar. So I'm wondering what's the point of letting Google index them? Moreover I think these form pages might suck out PR from all other pages that are more valuable for SEO. If your answer is "yes I would exclude them form indexing" would you simply use robots.txt to exclude them? Thanks!
