  • Removing existing filtered pages from Google's index: noindex / 301 / canonical to non-filtered page?

    - by Noam
    I've decided to remove some of my site's pages from the Google index to focus more of the indexed pages on higher quality pages. The pages I'm going to remove are already in the index. These removed pages are filtered pages which will continue to exist, I just don't want them in the google index because they add little quality to the same page without any filter selected. I've added in webmaster tools specification of narrow for the parameters that set these filters, but it doesn't seem this changes anything in how he handles these pages. So I'm considering three options: Adding <meta name="robots" content="noindex" /> to the html header of these filtered pages 301 to the non-filtered page that contains the most similar information and will remain in the index Canonical tag. Which I'm not sure is exactly the mainstream use case, as these aren't really the same pages. Which should I use?

  • Setting up collision using a tilemap and cocos2d

    - by James
    I'm building my first platformer using cocos2d and a tilemap. I'm having trouble coming up with a decent way of determining if the character is colliding with an object. More specifically, in which direction is the character colliding with an object. Following the tutorial here, I have made a separate "meta" layer of collidable tiles. The problem is that unless the character is in the tile, you can't detect the collision. Also, there's no way of telling WHERE the collision is occurring. The best solution would be one that could tell me if a character is up against a wall, or walking on top of a platform. However, I can't seem to figure out a good technique for this.

  • What are the tools required to build a compiler?

    - by kevin
    What are the various tools that are required to build a compiler for a particular programming language, say C? I want to know how each part of the compiler works. So, I am trying to use all the existing tools like loader, linker, etc, and combine them together to build one compiler (or can just say "compiling a compiler"). Can any one list out all such tools that are required to build a fully functional one?

  • Will polishing my current project be a better learning experience than starting a new one?

    - by Alejandro Cámara
    I started programming many years ago. Now I'm trying to make games. I have read many recommendations to start cloning some well known games like galaga, tetris, arkanoid, etc. I have also read that I should go for the whole game (including menus, sound, score, etc.). Yesterday I finished the first complete version of my arkanoid clone. But it is far from over. I can still work on it for months (I program as a hobby in my free time) implementing a screen resolution switcher, remap of the control keys, power-ups falling from broken bricks, and a huge etc. But I do not want to be forever learning how to clone ONE game. I have the urge to get to the next clone in order to apply some design ideas I have come upon while developing this arkanoid clone (at the same time I am reading the GoF book and much source code from Ludum Dare 21 game contest). So the question is: Should I keep improving the arkanoid clone until it has all the features the original game had? or should I move to the next clone (there are almost infinite games to clone) and start mending the things I did wrong with the previous clone? This can be a very subjective question, so please restrain the answers to the most effective way to learn how to make my own games (not cloning someone ideas). Thank you! CLARIFICATION In order to clarify what I have implemented I make this list: Features implemented: Bouncing capabilities (the ball bounces on walls, on bricks, and on the bar). Sounds when bouncing on bricks and the bar, and when the player wins or loses. Basic title menu (new game and exit only). Also in-game menu and win/lose menus. Only three levels, but the map system is so easy I do not think it will teach me much (am I wrong?). Features not-implemented: Power-ups when breaking the bricks. Complex bricks (with more than one "hit point" and invincible). Better graphics (I am not really good at it). Programming polishing (use more intensively the design patterns). Here's a link to its (minimal) webpage: http://blog.acamara.es/piperine/ I kind of feel ashamed to show it, so please do not hit me too hard :-) My question was related to the not-implemented features. I wondered what was the fastest (optimal) path to learn. 1) implement the not-implemented features in this project which is getting big, or 2) make a new game which probably will teach me those lessons and new ones. ANSWER I choose @ashes999 answer because, in my case, I think I should polish more and try to "ship" the game. I think all the other answers are also important to bear in mind, so if you came here having the same question, before taking a rush decision read all the discussion. Thank you all!

  • Scriptable user-interfaces/frameworks for automated UI testing

    - by AareP
    I'm planning on using scripting for automated UI testing. Main application is written in c#, and I want it to be scriptable, so I can do everything end-user can do, but programmatically. What do you think of software that provides an interface for scripting, like VBA macros in Excel? Can this be future of all programming, big and small? What is the best way to build such an interface for your own application, dll-based or by parsing own scripting language?

    - by Gaz Davidson
    Hi I'm an experienced programmer (C++, Java, Python, C, Objective-C, and others) and need to take a crash course in C# for my current job. I've never done any C# programming before though have read a bit about the syntax etc, I'm looking for a guide that quickly introduces advanced topics so I can get a handle on the language and begin hacking ASAP. Does anyone know of such a book? Amazon and Google are drawing a blank. Thanks in advance!

  • Importance of a 1st Class Degree

    - by Nipuna Silva
    I'm currently at the 3rd year following a degree in Software Engineering. I'm thinking of moving into a research field in the future (programming language design, AI etc.) My problems are, What is the advantage/importance of carrying a 1st Class Degree (Honors for Americans) in to the industry rather than with just simple pass. Is it really important to have a 1st Class? Is it the practical knowledge i have to give priority or the theoretical knowledge, or both?

  • Run On Sentences in Technical Writing

    - by Sean Noodleson Neilan
    This is just a question to think about. When you write technical documentation and programming comments, do you ever find yourself writing run-on sentences in order to be more precise? Is packing more technical information into one sentence better than creating many little sentences each with a little bit of technical information? I know it's better to have lots of little classes in their own little files. Perhaps this doesn't apply to writing?

  • How do I verify the ownership of a domain from Namecheap to use Google Apps?

    - by Rook
    I registered a domain with Namecheap.com, and started the Google Apps registration process. After the initial data filling, google apps wishes me to prove the ownership of a domain, and has given me 4 choices: Add a DNS record to your domain's configuration Link to your Google Analytics account Upload an HTML file to your server Add a meta tag to your site's home page What is the differences between these, and how do I (if someone knows perhaps how to do it on Namecheap, it would be even better) complete this step in the process? I would appreciate any advice you might have.

  • How will Qt 5.0 be packaged for Raring?

    - by George Edison
    Note: as per the FAQ, "Issues with the next version of Ubuntu" may not be asked as questions here but in my opinion, this is not an issue but merely a question asking about policy. If you feel this question is off-topic, please leave a comment explaining why or open a question on Meta.AU. How will Qt 5.0 be packaged for Ubuntu when it is released? Currently, the name of the package for installing the Qt 4.8 core libraries is: libqt4-core Will the equivalent package for the next version of Qt (5.0) be named libqt5-core? If not, what will the package be named? Will the existing Qt 4.8 libraries coexist with the Qt 5.0 equivalents for the foreseeable future or will they be removed? The Qt 5.0 beta 2 PPA contains a lot of packages - few of which seem to correspond with existing package names. If someone can provide me with a link to a policy outlining the Qt 5.0 migration plan, that would be awesome.

  • How to upgrade server from 8.10 to newer version?

    - by DisgruntledGoat
    I have a server still running Ubuntu 8.10. If I run apt-get update I get a bunch of 404 errors on the packages. I've asked a few questions on Server Fault but got nowhere. Here's what I've done: Run apt-get update which returns errors like: Err http://gb.archive.ubuntu.com intrepid/main Packages 404 Not Found [and same for many other packages] Run do-release-upgrade which returns: Checking for a new ubuntu release Failed Upgrade tool signature Failed Upgrade tool Done downloading extracting 'jaunty.tar.gz' Failed to extract Extracting the upgrade failed. There may be a problem with the network or with the server. Edited /etc/update-manager/release-upgrades and changed from Prompt=normal to Prompt=lts (as suggested here). Running do-release-upgrade after this returns: Checking for a new ubuntu release current dist not found in meta-release file No new release found So basically, it seems like I cannot upgrade because my current distro is out of date and not supported. Is there a way to upgrade direct to 10.x or 11.x?

  • Why&rsquo;s Poignant Guide To Ruby

    - by Liam McLennan
    According to Wikipedia, “why the lucky stiff was the persona of an anonymous, but prolific writer, cartoonist, musician, artist, and computer programmer”. He looks a bit like Jack Black. His book, Why’s Poignant Guide to Ruby, is a classic, though it can be hard to find since Why disappeared. If you want to learn the Ruby programming language I highly recommend Why’s Poignant Guide to Ruby. I am including a link here so that others who search for it may find it more easily.

  • 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?

  • How to make a license apply to a whole library?

    - by Yannbane
    I'm creating a standard library for a programming language, and I'd like to license each and every single class or function in there under the MIT license, so they're completely FOSS. All of the files reside in a single directory. Would it be enough to put a LICENSE.txt file in the same directory, containing the MIT license? Do I need to say that the following license applies to all features of the library, or is the library itself considered to be a program?

  • What effects do various drugs have on coding style / productivity? [closed]

    - by codecraft
    Can anyone tell me what the effect of various drugs are on coding style, and if coding on drugs can be more productive, or more fun? Are some types of drugs better suited to certain tasks and phases of software development? And which programming languages are best suited to coding on drugs? It would be great if you could back up your answers by data, probably even code snippets showcasing the effect of the drug experience.

  • 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...

  • administering new website - Found really tiny keywords inside page

    - by ndefontenay
    I'm administering this new website. The previous web admin included a large amount of tiny keywords on top of some of its pages. I've removed them already. I need to know if I have to rest the domain with google webmaster or will google notice the change and take action? thanks in advance. edit: They are not meta keyword. They are literally text so small that it looks like a fine line of gibberish on the page itself. This clearly violates google guidelines. My point was more: Do I need to tell google that we are not bad pupils anymore.

  • What are some reasonable arguments in favor of closed source software? [closed]

    - by Goma
    I like a technology (including programming language) but its platform is closed sourece and many times I meet people who ask me, "why do you use a closed source platform, why not use an open source alternative? If there is something wrong it should be with the closed source not with the open source, (as they say)". Actually I don't know how to answer their question. Could anyone tell me a good answer? Why do you use a closed source platform?
