  • Programming Interview Question [duplicate]

    - by user136494
    This question already has an answer here: How to prepare yourself for programming interview questions? [duplicate] 6 answers I have an upcoming interview in a couple of days and had a question for you guys. I've heard that programming interviews have whiteboard problems where you solve a simple problem on a whiteboard. My question to you is? How many whiteboard problems do you have to solve? Is there more than 1? What are examples of whiteboard problems? Is FizzBuzz one of them? Where can I find practice problems for them? Anyone know of any good web sites?

  • How do I get rid of duplicates in Rhythmbox even though the music in my Home folder is not showing duplicates?

    - by Drake
    I clicked import within Rhythmbox in Ubuntu 12.04 so I could get music to Ubuntu from my windows partition. The music appeared in my Rhythmbox library and I started playing it. However, when I restarted my computer the imported music did not show up. I looked in my music library and it was completely empty. So, I copied all of my music from my Windows partition into my music folder and launched Rhythmbox, but now it shows duplicates of all of the music I have. How can I get rid of the duplicate files if they are not showing in my Home folder?

  • How to remap CapsLock key to Ctrl in Xubuntu

    - by Evgeny
    I'm trying to remap my CapsLock key to Ctrl key as described here (adding /usr/bin/setxkbmap -option "ctrl:nocaps" command to "Session and Startup"-"Application Autostart"). But this doesn't work in Xubuntu 12.04. When I'm running the same command (/usr/bin/setxkbmap -option "ctrl:nocaps") from terminal everything works as expected. If I change command to: sh -c "/usr/bin/setxkbmap -option \"ctrl:nocaps\"" it again works if I'm running it from terminal, but it doesn't work if I add it to xfce "Session and Startup" configurator. Also when I create a script like this: #!/bin/sh /usr/bin/setxkbmap -option "ctrl:nocaps" and add it to startup via "Session and startup" configurator, it has no effect at all. But if I run this script after login it actually remaps caps key as expected.

  • How to disallow indexing but allow crawling?

    - by John Doe
    In the front page of my website, I have some previews to articles (with a small introduction to them) that link to the full articles. I want to disallow the front page to prevent duplicate content. But if I do this (in robots.txt), would it still be crawled? I mean, the full articles would be still reached by the crawler even though I disallowed the only page that links to them? I don't want the webcrawler not to access the page and enter the links in them, but I just don't want it to save the information (that will be repeated in the full articles).

  • Bug Tracking Etiquette - Necromancy or Duplicate?

    - by Shauna
    I came across a really old (2+ years) feature request issue in a bug tracker for an open source project that was marked as "resolved (won't fix)" due to the lack of tools required to make the requested enhancement. In the time elapsed since that determination was made, new tools have been developed that would allow it to be resolved, and I'd like to bring that to the attention of the community for that application. However, I'm not sure as to what the generally accepted etiquette is for bug tracking in cases like this. Obviously, if the system explicitly states to not duplicate and will actively mark new items as duplicates (much in the way the SE sites do), then the answer would be to follow what the system says. But what about when the system doesn't explicitly say that, or a new user can't easily find a place that says with the system's preference is? Is it generally considered better to err on the side of duplication or necromancy? Does this differ depending on whether it's a bug or a feature request?

  • Republishing blog posts on a popular website

    - by Giorgi
    I started my blog about programming yesterday and in order to promote and increase traffic I submitted my rss to Codeproject which pulls my posts and publishes them at Codeproject. While it increases the number of people reading my posts (but they are reading it at codeproject) I am worried that Google will penalize my site for duplicate content (Especially considering that Codeproject has much more reputation compared to my new website). The post at Codeproject has a link back to my blog post but it does not have "rel=canonical". So my question which one is better: a link from a high reputation website and some traffic or should I remove it from codeproject so that my blog is not penalized? What if codeproject adds "rel=canonical" to the link?

  • Pagination and duplicate content

    - by jazz090
    I have an archive page that displays the number of articles published. Because there were so many, I ran a pagination script: for 127.0.0.1/archive/2/?p=x&pp=y where p is the page number and pp is number of articles to display per page. The pagination looks like this: Prev 1 2 3 4 ... 12 NEXT with each item linking to p like <a href="?p=x">x</a>. I also have the items per page setter: 25 | 50 | 100 (<a href="?pp=y">y</a>). Now I have a PHP script that fixes pp into a session variable. But I am worried about duplicate content (since incrementing pp values will be inclusive) and also content not getting indexed because its not in the pagination link. so in the example above, pages 5-11 will not be indexed. Any ideas on how to fix this?

  • Preventing Duplicates on Google

    - by abel
    I am currently using a rewrite rule to enable access to .php pages, without using the php extension. However to prevent old links from breaking, the pages can still be accessed via links containing the .php extension too. For eg. domain.com/page.php can now be accessed at domain.com/page All the links on the website now use domain.com/page type links within the site. However older incoming links will still link to the .php pages, meaning Google will index both pages and mark them as duplicate. I have two plans to remedy the situation. Use a php 301 redirect: When a page is accessed with the .php extension, I can redirect each page individually using a 301 redirect using php Using Canonical: Place a canonical tag on each page, pointing to the ".php" less version My Question: Are both methods equally efficacious in preventing Google from indexing my ".php" pages? Which method should be preferred, by convention or otherwise?

  • Will having a website duplicated on multiple top level domains be penalised by search engines [duplicate]

    - by user1020317
    This question already has an answer here: Will having multiple domains improve my seo? 7 answers I'm running a website for a global company, and although we rank first in search engine results here in Ireland, a search done from other countries doesn't rank us as highly. If I register the domain at other top level domain names (eg. example.co.uk, example.nor etc.) and then just mirror the .com site to those other domains, will I be penalised by search engines for having duplicate content? Has anyone else faced a similar problem and found a way to capture the global search engine? Thanks.

  • Copying an SSH Public Key to a Server

    - by Nathan Arthur
    I'm attempting to setup a git repository on my Dreamhost web server by following the "Setup: For the Impatient" instructions here. I'm having difficulty setting up public key access to the server. After successfully creating my public key, I ran the following command: cat ~/.ssh/[MY KEY].pub | ssh [USER]@[MACHINE] "mkdir ~/.ssh; cat >> ~/.ssh/authorized_keys" ...replacing the appropriate placeholders with the correct values. Everything seemed to go through fine. The server asked for my password, and, as far as I can tell, executed the command. There is indeed a ~/.ssh/authorized_keys file on the server. The problem: When I try to SSH into the server, it still asks for my password. My understanding is that it shouldn't be asking for my password anymore. What am I missing?

  • Ubuntu 13.10 Security Key

    - by Toby J
    I was attempting to install Ubuntu 13.10 today and it came up with a screen asking for me to setup a security key. In the first place, I'm not sure what a security key is, but It said I would have to enter it everytime I booted Ubuntu so I assume it's the same thing as a logon password in Windows 8. Is there anyway I can bypass this step without setting up a security key or logon password? I hate these things and have always avoided them in Windows. I don't need them as there is never anyone but myself and my wife on our computers. We are retired, no children or nieces, nephews, friends, etc. who ever use our computer and we don't have any security information such as SS #, etc. on it. Also, I quit the installation at this point but I was not seeing any of the screen prompts as listed in the setup instructions on the Ubuntu website. Has the setup for Ubuntu 13.10 changed since these instructions were written? Thanks

  • Alt/Shift key not released after switching keyboard layout

    - by szx
    Sometimes when I switch layout using either Alt+Shift or Ctrl+Shift the Alt key is not recognized as being released thus if I press e.g. F a File menu opens up. Last time that happend I lost all data I filled into a text form on a webpage because I pressed the Home key while typing and Firefox suddenly went to my home page! Moreoever, it still remains unreleased after hundreds of keypresses like if I'm holding it! Same goes for the Shift key. I would rather file a bug at Launchpad if I could but I have no clue what fucking package name should I type in the ubuntu-bug command! Have anyone else had this issue? Can you suggest a solution or maybe another place to report this bug?

  • Will duplicate international (i18n) content hinder SEO rankings?

    - by Rhys
    Google clearly states that duplicate content within a single, or multiple, domains is not advised. This is understood, but I am not sure of any exceptions for sites with region-specific content that is often replicated across locales. For example, a site's /en-us/about page could be identical to /en-uk/about, whereas most likely /en-ja/about is unique. Are GYM smart enough to understand that the initial URL depth is a locale specifier? Is there any robots.txt or header, etc, trickery that I should include to outline the site's international structure?

  • seo value of duplicating content externally

    - by Don
    I run a website that includes a blog which was hand-coded by myself and is hosted on the same domain. My partner in this endeavour thinks it would be a good idea to open up a blogger/wordpress blog and duplicate the on-site blog on this off-site blog. AFAIK the main reason for doing this is the SEO benefits of the inbound links that this off-site blog will create. I think this is a bad idea, because: Effectively what we're doing is creating a (very small scale) link farm We're more likely to be punished than rewarded (in SEO terms) for duplicating our content across domains This introduces a problem of synchronising our content across domains. For example, if a blog post is edited on the on-site blog, then ideally the off-site blog should be similarly updated. I know very little about SEO, so would be interested to hear what more informed readers have to say.

  • Duplicate page content and the Google index

    - by Kit Sunde
    I have a static pages with dynamically expanding content that google is indexing. I also have deep links into virtually duplicate pages which will pre-expand the relevant section of content into the relevant section. It seems like Google is ignoring all my specialized pages and not putting them in the index. Even after going through web-masters tools, crawling and submitting them to the index manually. I also use the google API for integrating search on the site, and the deep linked pages won't show up. Is there a good solution for this?

  • Duplicate (Spotify) Icon in launcher

    - by user191231
    I have installed spotify on Ubuntu 13.04 and have locked the icon on the launcher. But when I exit the program fully or even restart and use that icon to open spotify, a new icon is created or a different icon is generated with a ? on it. It is a clean install of Ubuntu 13.04 so was wondering if this is a known bug or if there was a way of making sure it just doesn't created a duplicate icon? N.B it has not happened as of yet to any other program I have installed (Chrome & Steam)
