• Manually re-enable wireless and bluetooth

  - by tacozmeister

  So, today, I decided to turn off bluetooth to save battery power. When I did so, it did everything like normal. Whatever. But whenever I want to re-enable Wifi and Bluetooth, it just has "Enable Wireless" and "Enable bluetooth" grayed out in the respective things on the top-right of the desktop. I am using 12.04 Precise Pangolin on a Dell laptop that has never had wireless problems before. Clicking the grayed-out part does nothing. Re-logging and restarting has no effect, and I'm on an account that has full administrative permission. My attempts: ~$ sudo dmesg | grep wlan0 [19.960211] ADDRCONF(NETDEV_UP): wlan0: link is not ready . ~$ sudo dmesg | grep blue [[nothing]] What do I do to manually re-enable wireless and bluetooth?

• Rendering trillions of "atoms" instead of polygons?

  - by Baring

  I just saw a video about what the publishers call the "next major step after the invention of 3D". According to the person speaking in it, they use a huge amount of atoms grouped into clouds instead of polygons, to reach a level of unlimited detail. They tried their best to make the video understandable for persons with no knowledge of any rendering techniques, and therefore or for other purposes left out all details of how their engine works. The level of detail in their video does look quite impressive to me. How is it possible to render scenes using custom atoms instead of polygons on current hardware? (Speed, memory-wise) If this is real, why has nobody else even thought about it so far? I'm, as an OpenGL developer, really baffled by this and would really like to hear what experts have to say. Therefore I also don't want this to look like a cheap advert and will include the link to the video only if requested, in the comments section.

• Does having over 80% dynamic and rapidly changing content affect SEO?

  - by webmasters

  I have a website that pulls promotions of products from other website. My index page has a structure similar to this: My Brand - Best Promotions Looking for great deals? Check out our top promotions A menu - listing the promotions categories 20 of the latest promotions (the best ones): I list an image; Promotion description (200 chars); Link to the promotion page. Question: More then 80% of my index page (maybe even 90%) is composed of the 20 promotions I list; these promotions change on a daily bases - which dramatically changes the content of my index page. Does the dynamic changing of the index page affect SEO? Should I try to add more static text where I can? (which won't change) Ty

  I'm running out of space, so I tried to increase root size using this link: Increase size of root partition after installing Ubuntu in Windows Here is the output Filesystem Type Size Used Avail Use% Mounted on /dev/sda7 ext4 6,2G 5,6G 308M 95% / udev devtmpfs 965M 4,0K 965M 1% /dev tmpfs tmpfs 389M 892K 388M 1% /run none tmpfs 5,0M 4,0K 5,0M 1% /run/lock none tmpfs 972M 440K 971M 1% /run/shm /dev/sda5 fuseblk 12G 6,1G 5,8G 52% /media/Ubuntu /dev/sda2 fuseblk 278G 260G 19G 94% /media/AC4CC70D4CC6D16E I tried to allocate 16Gb in the host (/dev/sda2 which is windows 7 partition).

• Ubuntu 14.04 upgrade succeeded partially - I would like to use a different mirror; how can I do that?

  - by user290648

  When I wanted to upgrade from Ubuntu 13.10 to 14.04 the update manager told me that there was an unresolvable problem with calculating the upgrade. In order to see more details I performed the following on the command line: apt-get update apt-get upgrade apt-get dist-upgrade apt-get install update-manager-core do-release-upgrade Now do-release-upgrade tells me that no newer version is available but the "about" box in the main menu tells me I am still on 13.10. I think the latter is right, as for instance in the "system settings" there is no way to select local menus, which is present in 14.04 (I tried with a DVD, and there it is). Maybe the problem is related to the fact that "apt-get update" cannot get two resources called "saucy/InRelease" and "saucy/main/binary-i386/Packages" from the mirror (mirror.informatik.uni-mannheim.de; 404 not found). I would like to use a different mirror; how can I do that? Any help appreciated, thanks in advance.

• Is this the place to ask SEO questions [on hold]

  - by user39206

  I'm adding business listings to an existing website of which Google has sort of been referencing well but my Meta tags have a lot to be desired! Due to other work commitments I have kind of neglected the site but now think I should put the proper time and effort into getting it just right as it does earn me money. I am a developer so I have all the necessary skills to build the site, it's almost done!. Now I'm just a little worried that I could do something wrong and loose the rapport I've built up with Google in the past or be ban. Especially with the new tags I see like: <link rel=”publisher” href=”https://plus.google.com/[YOUR BUSINESS G+ PROFILE HERE]“/> Really I just want to know for now, is this the place to ask SEO question?

• How to compete in a Saturated Niche? [closed]

  - by jasondavis

  Possible Duplicate: Does the position of the content in the source make a difference to SEO? When entering a hugely over saturated niche such as web-design, is it even possible to compete with the big sites that have been ranked on google's #1 page for years? Also, I have read about how important titles, link anchors, and headings are for SEO and how content is the most important. So let's say we are building a standard header, body, sidebar, footer page. In the the actual markup, would it be better to make sure the main content comes before the sidebar on the page or does this probably not make a difference?

• ASP.NET MVC Multilingual Web Application

  - by BobhatePradip

  We are going to see how we can show localized content to your ASP.NET MVC web application. We will see mainly two approaches- Approach 1: Using Static Pages We can go for this approach only when we have few/limited static localized pages. Approach 2: Using Dynamic page with localized data at runtime We should go for this approach if we have large number of pages to show a data in localized format. In this approach we can either use resource file or directly data from database.   For details about the this check this link http://www.codeproject.com/KB/aspnet/ASP_NET_MVC_Multilingual.aspx Here you can have code sample with explanation.

• Design application to send messages by marking circle on the map where you want to send message

  - by jhamb

  This is question asked to me by an interviewer, in which a map of world is given, and for those country you want to send message, just marked circle on that area, and just send to all the people comes in that area. Question visual link is : Design this application The approach that I told him: Firstly build whole person's data (contacts , place information and all) Then where you mark on the map, just build a cluster of that country using Hadoop and fire the message to all the person's contact comes in that cluster. So help me for better understandings of this problem, and if have another good approach (all back-end ad front-end) , then please tell me or discuss here with me. Thanks in advance.

• Global variable in a Linux shared library

  - by user3730495

  Suppose we have the following setup under Linux, .so library named "libcnt.so" and 3 user space apps: "app1", "app2", "app3". This library does 1 simple thing, it says to the app (app dynamically links the library at runtime) by how many apps it is already linked. Apps should have access to link counter. My knowledge in C and Linux is somewhat limited in this aspect, but as I understand this information should be stored in a global variable inside the shared object. Something like: in libcnt.h extern int cnt_loads; in libcnt.c int cnt_loads = 0; // where each linking increments this counter or something... So, my question is how it should be declared and/or defined inside .so library to guaranty that multiple apps from user space get the same instance of that variable counter?

• Where is the source of domain search? [closed]

  - by All

  There are several websites providing service of searching for free domains (websites, not registrars). I wonder where is the source of these searches? This search cannot be based on local database, as it needs live data (of available domains). The only possible way (to me) is to fetch every query from the original NIC (e.g. nic.com), but I was unable to find an API for this service. How to find a source to write a script for domain searching?

• Initialize array in O(1) -- how is this trick called?

  - by user946850

  There is this pattern that trades performance of array access against the need to iterate it when clearing it. You keep a generation counter with each entry, and also a global generation counter. The "clear" operation increases the generation counter. On each access, you compare local vs. global generation counters; if they differ, the array has been reset. This has come up in StackOverflow recently, but I don't remember if this trick has an official name. Does it? One use case is Dijkstra's algorithm if only a tiny subset of the nodes has to be relaxed, and if this has to be done repeatedly.

• Pitfalls of using a WYSIWYG editor? [closed]

  - by user50849

  I'm interested in reasons for disallowing content editors on medium to large sites, from using various forms of WYSIWYG editors. A common problematic scenario I can think of is that with the use of a WYSIWYG, an editor uploads an image "somewhere" to the file-system, inserts it directly into the text, and publishes the article. Shortly afterwards, someone wants to pull out "The last 10 uploaded images", and display them on the frontpage. Good luck parsing all the content. Taking a look around at some large international online magazines, such as http://www.time.com/, and some local ones, I see that the editors seem to produce articles that are almost only consisting of raw text. Images are usually at the top of the article, and otherwise the most complex content are usually links. What are some common reasons for refusing editors access to WYSIWYG tools?

• Access to my files on Android

  - by user18644

  I am thinking of subscribing to Dropbox which is slightly more costly than Ubuntu one but I need access to my files on the go, and I prefer to use my smartphone to my netbook most of the time as I like to travel light. I do not want to stream music, I want access to my files only. Whereas there is a free app for Dropbox to access said files, there isn't one for Ubuntu. I would be prepared to wait a while if you have got this in hand, have you actually given this any thought? Please tell me whether I should ignore Ubuntu One and link up with Dropbox?

• php cms withouth database

  - by user1791795

  A friend of mine asked me for a easy website for him. As it was just 3 subpages, no database need or anything, I've done it quite fast with plain PHP, HTML, JS and CSS. But then another and another friend showed up. They only wanted arrange differently they navigation, some different picutures etc. So I though, is there any kind of CMS, that allows build small business website (barbershop, local groceries shop), with small list of subpages, yet allowing us to arrange look'n'feel. There's no need for the databas as content won't change, or can be stored in simple textfiles for example. Things like WordPress might be simple overkill Does anyone know such cms?

• Game Object Design

  - by oisin

  I'm having a problem with the way I designed my first simple game in C++. I have GameObject (abstract class) and ObjectA which inherits the update() and draw() methods from GameObject. My main loop contains a linked list of GameObject*, and while that list is not empty it cycles through it, calling update on each one. Up until this point, I thought the design was standard(?) and would work. However, when I call update on ObjectA() I run into two problems: ObjectA can die which messes up the list, which in turn throws off the loop in main. ObjectA can spawn more ObjectA's but these are local scope and the update() goes out of scope, creating problems in main's list of GameObjects. I think my design if alright, but I'm having such problems with segmentation faults that there must be something seriously wrong with at least one part of my implementation. If anyone could point out any serious mistakes or simple examples of this being done (or even alternative designs) then I would greatly appreciate it!
