• SEO - Hidden content before main site content

  - by 0pt1m1z3

  I have a two hidden divs before my main site content, one with the login form and another with the signup form. I then have login and signup buttons within the page that use JQuery to show or hide these divs. I like the effect this setup offers, dropping down from the top of the page and pushing the rest of the content down. However, recently I have been getting serious about SEO and I am wondering if these divs have been affecting my SERP rankings. Basically, every non-logged page (everything bots see) has the same two display:none; divs at the top of the document flow. Is it bad? Should I re-engineer these forms and the way they are displayed?

• Screen Resolution Problem with Ubuntu 14.04 and VirtualBox

  - by user3341257

  Environment: Lenovo T530 running Windows 7. Have installed Ubuntu 14.04 on a virtual machine using VM Virtual Box. Have installed all the updates from both Virtual Box and Ubuntu. Problem: While in Ubuntu's desktop and other Ubuntu initiated programs, the window is reduced to about 3x4 inches showing in the middle of the rest of my regular Virtual Box window. I am seeing only the upper right hand of the screen output of what I would normally see. Please help. I've seen How do I install Guest Additions in a VirtualBox VM? But, none of these answers works in 14.04.

• What technology to use for turn-based game server? [closed]

  - by mekanikus

  If I create a mobile turn-based game which could consist from 2 up to 6 players. I expect the server to support for about hundreds of game. And I aim for something free and not costly technology. What software and hardware recommendation would be enough for me? I've found some game server engine such as photon. But is it too much for a simple game? I'm thinking of using REST technology with F3 PHP server and Mysql. Will it be adequate? Will only one physical server enough? What is the hardware recommendation for the server?

• Should I add rel nofollow to internal links which already have meta noindex?

  - by CamSpy

  Let's say I have a products page with listing producsts and the page has pagination. I would like the 1st page to have all the SE ranking weight so I decided to put meta noindex on the rest of the paginated pages (from page 2 to N). My common sense says that if I don't want pages to not get indexed, I shouldn't also pass link/PR juice to these pages. (Is that smart?) What happens if I set rel="nofollow" for all pagination links from page 2 to page N?

• Where's Gangnam?

  - by Mike Dietrich

  When somebody did mention "PSY" during a dinner at OOW this year with customers and colleagues from Korea I was completely clueless. I even didn't understand correctly who or what "PSY" is. I did forget about that until last week as a German online magazine did report on over 500 mio youtube hits for "Gangnam Style". Well ... I didn't know that I've almost missed a global phenomenon. And now I've learned that the song is omnipresent in Korea (and not only here) - and Gangnam is a really nice (and expensive) quarter of Seoul not that far away from my hotel. And if you need some rest during your lunch break you may watch these youtube vids - but don't blame me if you don't get the song out of your head anymore ... Gangnam Style by PSY Eton Style - my personal favorite Jakarta Flash Mob - wow! And NO - that's not the type of music I'd usually listen to!!!

  - by hustlerinc

  I have a map array with objects stuffed with variables looking like this: var map = [ [{ground:0, object:1}, {ground:0, item:2}, {ground:0, object:1, item:2}], [{ground:0, object:1}, {ground:0, item:2}, {ground:0, object:1, item:2}] ]; Now I would like to be able to delete and add one of the variables like item:2. 1) What would I use to delete specific variables? 2) What would I use to add specific variables?

• Chameleon effect not working after update

  - by Roshnal

  I've been using Ubuntu 12.04 since it came out and so far didn't have any problems with it. But after I updated (via Update Manager) it yesterday, after every reboot, the launcher color defaults to a blue dash, workspace and trash icon and the rest is black. If I set the wallpaper again manually, then it changes color as its supposed to (chameleon). Any idea why this is? Its really annoying to change your wallpaper every time you logon just to get the "normal" launcher. EDIT The chameleon effect works perfectly for notifications. Only the Launcher and Dash are not changing the color. Thanks.

• Strange behaviour when screencasting

  - by Luis Alvarado

  Since an update I did yesterday I am not able to screencast any video using Kazam, Recordmydesktop or even ffmpeg/aviconv. After the upgrade to some libraries (A normal update that showed in Update manager) the problem was this: When doing the screencast, scrolling inside an Apps window like Firefox, Chrome or Gedit is not shown. The video only shows the last image it recognized before I started scrolling. For example with Gedit, I have a lot of text on it and when I start to scroll down, the video only shows what I had in the beginning while I listen to myself talk about what is in the rest of the file (Which is not shown in the video). When opening a window, for example again Gedit or Chrome it might not show in the video, it will just show the desktop without the window opened. I do not see any error with dmesg, syslog or others. What can I check to debug this problem?

• Jersey 2.0 Milestone 2 Now Available

  - by arungupta

  Jersey 2.0 milestone 2 is now available. It builds upon the first milestone and adds several new features such as server-side asynchronous processing, server-side content negotiation, improved JAX-RS parameter injection, and several others. The REST endpoints can be published on Java SE HTTP Server, Grizzly 2 HTTP container, and some basic Servlet-based deployments. It also provides HTTPURLConnection-based client API implementation. Read about these and more about what's new in Marek's detailed post. Of course this is also the future reference implementation for JAX-RS 2.0. Feel like trying it out? Simply go to Maven Central (of course none of this is production quality at this point). The latest JAX-RS Javadocs and Jersey 2.0 API docs are good starting points to explore. And provide them feedback at [email protected].

• Black screen on Ubuntu 12.04

  - by user1648371

  I've just upgraded to Ubuntu 12.04 and I'm experiencing some problems. The first thing I noticed is that when I click the Workspace switcher all I get is a black screen (I can guess where the different workspaces are located and clicked on them, not a practical solution though). In addition when I lock the screen or suspend the laptop (a Vaio VPCEB4M1E) I get a shifted screen (I see the right most vertical stripe on the left size of the monitor and nothing about all the rest, to put it clearly I can see the gear that allows me to turn the pc off, etc, but not much more..) when I go to the additional driver menu I see the "ATI/AMD proprietary FGLRX graphics driver" are installed and the post-release update version is available. I don't know if the problem is driver related, so before doing anything I'd like to get some suggestions from you guys. Thanks you!

• Rendering only a part of text FTGL, OpenGL

  - by Mosquito

  I'm using FTGL library to render text in my C++ project. I can easily render text by using: CFontManager::Instance().renderWrappedText(font, lineLength, position, text); Unfortunately there is a situation in which this Button which displays text, is partly hidden because of resizing container in which it is situated. I'm able without any problem to draw Button's background to fit the container, but I've got a problem with doing the same with a text. Is it possible to somehow draw only text for given width and the rest just ignore? This is a screen which presents my problem: As you can see, the Button "Click here" is being drawn properly, but I can't do the same with "Click here" text.

• Can't cancel the lubuntu shutdown screen

  - by user292040

  I've bought a small 5 year old small netbook. I noticed that lubuntu runs great on it, as it doesn't use much space/resources. But the problem is, my screen is just too small. Whenever I press the shutdown icon, I go to the shutdown, logout, restart, ect panel but the cancel button is tucked away right where my screen seems to end. I can't go back, it forces me to use an option besides canceling, which I can't reach with my mouse.Is there any way to change this so I get access to the whole screen. The rest seems to be showing just fine, like the launchbar, which is cleary visible and useable. Another thing that bugs me is that whenever I start up, I get an error along the lines of "conflict detected with stolen region". I read that it has something to do with graphics but I have no idea how to get rid of it. The error doesn't seems to cause any trouble as far as I can see, but it's annoying.

• Access samba shares befor login

  - by everlearnin

  I installed Ubuntu 12.10 on an old Compaq C300. I want to use it to share my movies over lan so that the rest of my family can watch without hi-jacking my pc. I installed samba and shared the Public folder under the Home folder of my user account. But I can only access this folder from my Win 7 pc when I am logged in. If I log out or restart without logging in then I cannot access the shared folder. I am used to the Windows service that starts at boot making shared files available over the network before the user has logged in. How can I accomplish this in Ubuntu?

• Hello!

  - by barryoreilly

  After many months of deliberating I have finally gotten around to starting this blog! The reason for doing this is the large number of half finished articles lying around on my hard disk, unpublished and unloved. These articles have been of huge benefit to me, and have been written in an attempt to consolidate my own thinking, in order to help me structure my thoughts and ideas as I have tried to digest new ideas and understand abstract theories. It is my hope that by tidying up these articles and publishing them here that I can continue this learning process by getting feedback on the ideas from within the developer community. i have worked with .NET for 8 years now, and have worked with ASP.NET, SQL Server, Windows programming as well as general network administration. Since 2004 my focus has been on integration, web services, and more often than not Biztalk Server. The last two years have seen me focus on SOA and WCF, and the Managed Services Engine, so this is probably where the main focus of the blog will to start with, but there are so many fun things to play with these days that i have no idea where it will end up.....   Barry

• When should I clear an auxilliary render target?

  - by Raptormeat

  I'm using a few different render targets in my game in addition to the back buffer. These other render targets are only used in a few places, for specific tasks. I'm wondering when I should be clearing them. Right now I clear all of my render targets at the beginning of the frame, and it seems like I'm waiting for all the textures to clear before the rest of the drawing gets underway. Would it be more efficient to clear these textures later in the frame, when they aren't being used? Is there any hope of the GPU sort of clearing them "on the side" while unrelated rendering is happening? Or are these tasks always sequential and will I always need to wait for clearing?

• Leapfrog Crammer won't mount as a USB flash drive

  - by William

  I can't seem to get the Leapfrog Crammer study and sound system to show up as a flash drive under ubuntu so I can transfer stuff to it. I don't want to install the leapfrog bloatware, can someone help me with this? Additional Information: When I plug my crammer into my computer it shows a 1 MB file system with a link to download the crammer software. I want to know how to access the rest of the crammer's file system so I can transfer music to it. The crammer does not show any other partitions in natulius. According to an article on the internet, the crammed is divided into three partitions: One with a link to install the crammer software, one with all content(music, flash cards, etc.) and one for firmware. I want to know how to access the one with the content so I can add music to the player. Can anyone help me with this? Thanks in advance.

• Azure Table&ndash;Entities having different Schema (Implementation Approach)

  - by kaleidoscope

  Below is the approach that can be implemented whenever there is a requirement of creating an Azure Table having entities with different schema definitions.   We can have a Parent Entity defined which will hold the data common in all the entity types and then rest all entities should inherit from this parent class. There will be only on DataServiceContext class which will accept the object of the Parent class and this can be used for CRUD operations of all the entities. Hope this approach helps! Thanks.

• Improving FAQ SEO with multiple pages?

  - by asdfasdf

  I have a client who has over 200 Question/Answer style content blocks. Neither the questions or answers are very long and most of them have almost the same question but with a word or two differentiating themselves from the rest of the questions. Would SEO be helped or hurt if I would to put each QA on its own page with the title of the page the question being asked etc... Or, would that be considered "farming"? If not, what would be the best way (in SEO world) do present all these QAs? Thanks for any advice..

• Is it better to use preprocessor directive or if(constant) statement?

  - by MByD

  Let's say we have a codebase that is used for many different costumer, and we have some code in it that relevant only for costumers of type X. Is it better to use preprocessor directives to include this code only in costumer of type X, or to use if statement, to be more clear: // some code #if TYPE_X_COSTUMER = 1 // do some things #endif // rest of the code or if(TYPE_X_COSTUMER) { // do some things } The arguments I can think about are: Preprocessor directive results in smaller code footprint and less branches (on non-optimizing compilers) If statements results with code that always compiles, e.g. if someone will make a mistake that will harm the irrelevant code for the project he works on, the error will still appear, and he will not corrupt the code base. Otherwise he will not be aware of the corruption. I was always been told to prefer the usage of the processor over the usage of the preprocessor (If this is an argument at all...) What is preferable - when talking about a code base for many different costumers?

• Usefull skills from a computer science degree

  - by Tom Squires

  I did my degree in physics and moved later into programming. I have two and a half years experience under my belt and like to think I write good code. I am, however, concerned that not doing a compsci degree has left holes in my knowledge. I would like to fill those up now since I know I want to be doing programming for the rest of my career. What skills/techniques did you learn in your compsci degree that one wouldn't pick up from on-the-job programming?

• Modern website/webapp setup

  - by onepiece

  I'm new to web development. From looking at popular open-source frameworks for both front-end and back-end, I have a general idea of what the modern full-stack web setup looks like: Database <- Back-end language ~ REST API <- Front-end Notes: The back-end language (Python, Ruby, PHP, Java) generates the API, which is the only layer between the back and the front. The API will have authentication to protect private data. The front-end sends GET and POST requests to the API. A MVC framework can be used, such as Backbone, Angular, or Ember.js. Does this align with best practices for web development?

• Limiting the speed of a dragged sprite in Cocos2dx

  - by Frozsht

  I am trying to drag a row of sprites using ccTouchesMoved. By that I mean that there is a row of sprites (they are colored squares) lined up next to each other and if I grab one with a touch the rest follow it. However, if the sprite that is selected by touch moves too fast it creates a slight gap between it and the following sprites. How do I go about limiting the speed that I can drag the sprite with ccTouchesMoved? This is the only solution I could think of to my problem. If anyone has another suggestion to prevent this sprite gap from happening I would appreciate it.
