• why doesn't my computer resume after sleeping overnight?

  - by bamdad

  i'm having a weird, weird bug that's been haunting me since 11.10. if i listen to music or watch a video and my computer automatically goes to sleep at night, it won't properly resume in the morning. otherwise, suspend and resume works just fine. what happens is that the wi-fi and bluetooth indicator (that turns from white to orange when suspending) stays orange, the display doesn't turn on, and the only option i have is to hard reset the machine. here's what i've tried so far: installing (and uninstalling and reinstalling) laptop-mode-tools switching the proprietary wireless driver (broadcom-wl) to the open source one (brcmsmac & bcma) and back unloading (and blacklisting) all bluetooth modules (rfcomm, btusb, bnep, bluetooth) and stopping (# stop bluetooth) and disabling (# echo 'manual' /etc/init/bluetooth.override) the bluetooth service creating a custom pm sleep action as suggested here: http://ubuntuforums.org/showthread.php?p=11926504 not watching youtube / any stuff that uses flash before going to sleep (i have flashblock, and i checked $ ps aux | grep flash) because i suspected flash to be the culprit trying out different versions of fglrx (the one from the repos, then installing the latest one from amd's site via generated .deb files, then back to the official ones) none of these worked. i remember back in the days of 10.04, there was a gconf key called network sleep: i thought about disabling that, since re-enabling the wireless card seems to be the problem (according to the indicator led), but the option appears to be missing from gnome 3 (unity-2d, whatever). does anyone have any ideas? thanks, bamdad

• Does it make sense to write build scripts in C++?

  - by Klaim

  I'm using CMake to generate my projects IDE/makefiles, but I still need to call custom "scripts" to manipulate my compiled files or even generate code. In previous projects I've been using Python and it was OK, but now I'm having serious trouble managing a lot of dependencies in two very big projects I'm working on so I want to minimize the dependencies everywhere. Someone suggested to me to use C++ to write my build scripts instead of adding a language dependency just for that. The projects themeselves already use C++ so there are several advantages that I can see: to build the whole project, only a C++ compiler and CMake would be necessary, nothing else (all the other dependencies are C or C++); C++ type safety (when using modern C++) makes everything easier to get "correct"; it's also the language I know the better so I'm more at ease with it even if I'm able to write some good Python code; potential gain in execution speed (but i don't think it will really be perceptible); However, I think there might be some drawbacks and I'm not sure of the real impact as I didn't try yet: might be longer to write the code (that said I'm not sure because I'm efficient enough in C++ to write something that work quickly, so maybe for this system it wouldn't be so long to write) (compilation time shouldn't be a problem for this case); I must assume that all the text files I'll read as input are in UTF-8, I'm not sure it can be easilly checked at runtime in C++ and the language will not check it for you; libraries in C++ are harder to manage than in scripting languages; I lack experience and forsight so maybe I'm missing advantages and drawbacks. So the question is: does it make sense to use C++ for this? do you have experiences to report and do you see advantages and disadvantages that might be important?

• Which Language Next? Python? Ruby? [closed]

  - by Ryan Craig

  I am a beginning Webmaster (relatively), with 2+ years of php experience. I also have some java training and a bit of .net. My company is now close to redeveloping the website that I work on, which is coded primarily in php, but has some poorly-written .net in part as well (it's confusing and ill-planned, but I didn't make any of those decisions. Can anyone say action-oriented .net and JScript?). So, I'm trying to decide which language I should learn next to quickly develop a new site. I will probably just redevelop it at first in php because I'm very comfortable with it. However, I'd like to migrate in the next year to something newer and more forward-thinking. This being said, .net is out of the question a little bit. We need cheap developers who are fast and can get pages up quickly. In this part of the country, part-time .net developers are hard to find. So, we need something that will be pretty standard in the next few years, but we have some .net SOAP 1.1 APIs that we use on our actual service (separate from the corporate website), that we will need to integrate part of the site with. Developing with php and SOAP is much more difficult than doing the same thing. So, I may have to develop the API collaborative part in .net just to be easy, and then I'd like to use something else that is fast, flexible, forward thinking, and will be relatively standard and easy to find developers for. So, any ideas? Python and Django? Ruby on Rails? Another framework? Thanks for your thoughts. Sorry, I know this was long, but it's all very convoluted and confusing so I needed to be slightly long-winded.

• Modular Architecture for Processing Pipeline

  - by anjruu

  I am trying to design the architecture of a system that I will be implementing in C++, and I was wondering if people could think of a good approach, or critique the approach that I have designed so far. First of all, the general problem is an image processing pipeline. It contains several stages, and the goal is to design a highly modular solution, so that any of the stages can be easily swapped out and replaced with a piece of custom code (so that the user can have a speed increase if s/he knows that a certain stage is constrained in a certain way in his or her problem). The current thinking is something like this: struct output; /*Contains the output values from the pipeline.*/ class input_routines{ public: virtual foo stage1(...){...} virtual bar stage2(...){...} virtual qux stage3(...){...} ... } output pipeline(input_routines stages); This would allow people to subclass input_routines and override whichever stage they wanted. That said, I've worked in systems like this before, and I find the subclassing and the default stuff tends to get messy, and can be difficult to use, so I'm not giddy about writing one myself. I was also thinking about a more STLish approach, where the different stages (there are 6 or 7) would be defaulted template parameters. Can anyone offer a critique of the pattern above, thoughts on the template approach, or any other architecture that comes to mind?

• Run external application on markdown source in ikiwiki

  - by student

  Can I add a button to each wiki page in ikiwiki which launches an external application (on the client side) or script with the markdown code of the current page as input? Edit: I didn't realize that it might be complicated to do it on client side as Zenklys' answer suggested. So perhaps I should describe more concretely what I have in mind: I want to have two buttons: "Get LaTeX" and 2. "Get pdf". Clicking on "Get LaTeX should generate a LaTeX file and the browser should simply open or download that file. Analogously for the pdf. It would even be ok, to have a button "Generate LaTeX" instead, which generates the LaTeX code and changes after the generation to "Get LaTeX" which simply points to the LaTeX file. So it is not really necessary to do the generation of the files on client side. Would be ok, if this is done (on a temporary folder) on server side. For the LaTeX resp. pdf generation I want to use a custom wrapper script for pandoc, let's call it mymarkdown2latex resp. mymarkdown2pdf.

• Move unity launcher to bottom of the screen

  - by argvar

  I have Ubuntu 13.04 DESKTOP version and for some odd reason I'm told that the Unity launcher cannot be moved to the bottom of the screen because of several reasons: 1. Canonical wants it there so it fits with their overall design goals, namely when it comes to touchscreen devices and netbooks. This in my mind totally ignores the fact that most Ubuntu users are DESKTOP users. No matter what Canonicals long term goal is, it surely mustn't be at the expense of needs of their core user base. 2. Most monitors are widescreen, the launcher is more compact where it is. This is not only taking away the users choice, but is also a wrong assessment. Widescreen monitors can sometimes be rotated on a pivot, giving it a portrait aspect. By displaying the Unity launcher on the left side it takes up a lot of space. Many desktop users have multiple monitors, and having the launcher on the left side of each monitor is very awkward. Also, many websites are catered to fit on a half 1920 display, so you can have two browser windows open side-by-side with all content visible. The placement of the Unity launcher takes away the horizontal space meaning there's less room for each browser window, and you'll see the right side of the web pages being occluded. Any suggestion to simply hide the Unity launcher, or "Canonical knows best" or "get used to it" are unwelcome and totally ignores the above points. Linux is about choice. Canonical's stubbornness with the Unity launcher placement is inconsistent with what Linux is about.

• Not able to track traffic on subdomain using Google Analytics

  - by Steven

  I'm trying to track traffic for my sub-domain, but it's not happening. This is how it's set up. My partner has a domain called sub1.partner.com. This domain points to partner1.mydomain.com. The idea is that users think they are browsing my partners website, when they are in fact browsing pages on my server. My tracking code looks like this: var _gaq = _gaq || []; _gaq.push(['_setAccount', 'UA-xxxxxxxx-x']); _gaq.push(['_setDomainName', '.mysite.com']); _gaq.push(['_trackPageview']); (function() { var ga = document.createElement('script'); ga.type = 'text/javascript'; ga.async = true; ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(ga, s); })(); In Google analytics I've created a new account under my main account and called in partner1.mysite.com. On this account I have created a filter: Filter type: include Filter field: Host name Filter pattern: partner1.mysite.no Case sensetive: No What more can I try to track traffic on my subdomain? UPDATE Question 1 Is this line correct? _gaq.push(['_setDomainName', '.mysite.com']); Question 2 Is it correct that I have to add \ before any punctuations like so \. in filters?

• Can too many 301 redirects cause a DNS error?

  - by Graham

  For a site http://imageocd.com that I just set up I initially spelled the category "automobiles" as "autimobiles"... I know it's rediculous. I then set up over 10,000 pages behind that category e.g. http://imageocd.com/automobiles/hillman-minx-cabrio-pictures-and-wallpapers. So, I set up over 10,000 301 url redirects to change the spelling on automobiles. I just checked my Google Webmasters report and got an error saying: http://www.imageocd.com/: Googlebot can't access your siteSep 7, 2012 Over the last 24 hours, Googlebot encountered 2 errors while attempting to retrieve DNS information for your site. The overall error rate for DNS queries for your site is 66.7%. Could the overabundance of 301 redirects be causing this? I host 13 sites on this dedicated server and all sites are running fine. I also contacted GoDaddy and they said the server is running fine. Any ideas on what might be going on? Also, I have "canonical" set up for every URL. Could this be part of the error? Thanks.

• How can we best petition to bring Adobe creative software to Ubuntu?

  - by Sixthlaw

  Now I know its not as simple as asking for Adobe to support their design software on Ubuntu, but is there a way for the community and Canonical to make known to Adobe the rapidly growing amount of Linux users, and their desire for this great set of tools OFFICIALLY? I know that many of the answers I receive might be of the fashion "Its not going to happen", "use the free tools provided" or "Who knows it might happen in the near future", but this IS not what I am looking for. I have noticed, on sites like www.OmgUbuntu.com, there are links to pages where people can "like" the idea. Is there a way to try and get the whole community on board with this one, even Canonical, and as stated above, put forward this proposal to Adobe. The current requests for an Adobe CS, for Linux, are in dribs and drabs scattered all of the internet. Now is the best time to come up with productive solutions on how we can best gather statistics on the amount of people willing to buy the Adobe CS. These are the words of an Adobe employee: "I have forwarded this feedback on to the appropriate team who will consider it for future releases of Adobe software." The larger amount of people we have unified in the ONE community proposal, the greater chance we have of getting the software. How can we make this happen?

• Using a CDN for CMS software (multiple sites)

  - by SmokeyPHP

  I'm currently researching ideas for the media management side of a CMS I'm writing. I was looking at having images served from a CDN which is fine on a single site, but I want all sites that run the CMS to make use of a CDN (which will most likely be a custom developed one, rather than a third party service like S3). My main question is: Is a multi-site CDN a good idea? I can't think of a downside, but have probably missed something - obviously they won't share the same folder, as I invisage the requests to be css.cdnsite.com/example.com/style.css or something along those lines. Having multiple sites in the same place will obviously make it easier for us to manage, as well as being cheaper, but then I wonder if it'll be worth it... Long story short: How should the CMS handle user uploaded media (separate installations) Just keep a local copy of all assets and serve them from the same site, like in days of yore? Keep a local copy, force site to use www. and have CDN subdomains per site? Or use a single separate CDN for all sites? Apologies for the length of this question, not sure if this should be multiple questions or not, as all parts are kind of related and could affect each other.

• POLL: How do you build your interfaces in xcode for iphone/coco-touch applications?

  - by LolaRun

  Hi all, It's been 2 months i'm using xcode and building iphone apps, and i'm finding it really hard to grasp the good design for the applications. I always face problems like you can't put your tabbarcontroller in another custom viewcontroller sort of a thing? or other problems... That 'sometimes' - of course - would work if you did the creation of the views/viewcontrollers programmatically. so I don't know if i should start writing the creation of my objects or use interface builder. This is why i'm asking this poll question, to see what's the most accepted way among other developers. I'm not going to answer my question, so the votes would not increase my reputation and risk my poll being closed soon. I prefer that the first two readers of this question should answer by 'using IB' and the second one 'programmatically' and the rest would vote up or down for these two answers. And don't vote my question either, i just need to know, and maybe someone else wants to know. so the longer this question lives the better. and gaining nothing from it concerning reputation would help that cause. thank you all for your cooperation. and go ahead and answer Peace

• Light on every model and not in the whole scene

  - by alecnash

  I am using a custom shader and try to pass the effect on my Models like that: foreach (ModelMesh mesh in Model.Meshes) { foreach (ModelMeshPart part in mesh.MeshParts) { part.Effect = effect; } mesh.Draw(); } My only issue is that every Model now has its own light source in it. Why is this happening and is this a problem of my shader? Edit: These are the parameters passed to the shader: private void Get_lambertEffect() { if (_lambertEffect == null) _lambertEffect = Engine.LambertEffect; //Lambert technique (LambertWithShadows, LambertWithShadows2x2PCF, LambertWithShadows3x3PCF) _lambertEffect.CurrentTechnique = _lambertEffect.Techniques["LambertWithShadows3x3PCF"]; _lambertEffect.Parameters["texelSize"].SetValue(Engine.ShadowMap.TexelSize); //ShadowMap parameters _lambertEffect.Parameters["lightViewProjection"].SetValue(Engine.ShadowMap.LightViewProjectionMatrix); _lambertEffect.Parameters["textureScaleBias"].SetValue(Engine.ShadowMap.TextureScaleBiasMatrix); _lambertEffect.Parameters["depthBias"].SetValue(Engine.ShadowMap.DepthBias); _lambertEffect.Parameters["shadowMap"].SetValue(Engine.ShadowMap.ShadowMapTexture); //Camera view and projection parameters _lambertEffect.Parameters["view"].SetValue(Engine._camera.ViewMatrix); _lambertEffect.Parameters["projection"].SetValue(Engine._camera.ProjectionMatrix); _lambertEffect.Parameters["world"].SetValue( Matrix.CreateScale(Size) * world ); //Light and color _lambertEffect.Parameters["lightDir"].SetValue(Engine._sourceLight.Direction); _lambertEffect.Parameters["lightColor"].SetValue(Engine._sourceLight.Color); _lambertEffect.Parameters["materialAmbient"].SetValue(Engine.Material.Ambient); _lambertEffect.Parameters["materialDiffuse"].SetValue(Engine.Material.Diffuse); _lambertEffect.Parameters["colorMap"].SetValue(ColorTexture.Create(Engine.GraphicsDevice, Color.Red)); }

• MVC: Nasty __o not declared

  - by xamlnotes

  I ran into this little error with MVC where a bunch of errors showed up about  __o  not declared. This was driving me nuts. Then I ran across this link that solved it. http://stackoverflow.com/questions/750902/how-do-i-get-rid-of-o-is-not-declared So, the solution is to put this into the top of the page like VS does for your site.master. <%-- The following line works around an ASP.NET compiler warning --%> <%: ""%> But what about other pages? Lets say you have a view that’s using your site master and that view is throwing this error. Just add the items into the content section where the error occurs like so: <asp:Content ID="indexContent" ContentPlaceHolderID="MainContent" runat="server"> <%-- The following line works around an ASP.NET compiler warning --%> <%: ""%>   Then add the rest of your code. That seems to fix it and its pretty simple too.

• Google is displaying "Translate this page" based on a previously registered domain inbound links

  - by crnm

  I recently started a new project with a newly registered generic tld domain. As soon as Google started indexing the page, it displayed a "translate this page" in SERP's, which tries to translate the page to the language of a small Eastern European country from the language that the site actually uses. I tried everything to prevent this: language meta headers and attributes, localisation through Google Webmaster Tools...all to no avail - nothing helped. After a couple of weeks I spotted dozens of inbound links popping up in Google Webmaster Tools all coming from that small Eastern European country, from sub-pages that are not active anymore (either sending out 404's or 301's to the main page), and also had been written in that other language. So the domain had been registered before and as it looks, it did got a lot of possibly spam links in that language. I can't even ask the sites where those links should have been to remove them as they are not active anymore physically, just in Google Webmaster Tools and/or internal data masses... Now I'm at a loss about what to do? As my site is pretty new, it does not have many links pointing towards it in my targeted language. So those are probably not enough to convince Google of attaching the right language to it as Google ignores all other signals about the page language. I'm also unsure if I should use the "disavow" tool, or a reconsideration request...or what else to do about this miserable state. I never used these tools before so I don't have any experience with them. Somehow I have to convince Google about the right language of the page and also to not count/apply/whatever all those historical links from the previous owner. (The domain had been deleted without any traces in Google before I registered it) Has anyone here ever dealt with a similar "Translate this page" problem? (I've also looked at this thread: How can I prevent Google mistakenly offering to translate a page? but didn't find a solution there)

• Simple Introduction to using the Enterprise Manager SOA/BPM Facade API by Jaideep Ganguli

  - by JuergenKress

  There may be times when you need to expose just a small section of what is displayed in the Enterprise Manager console for SOA/BPM (EM console). A simple example can be where stakeholders on the systems integration or customer teams want to monitor a dashboard of statistics on how many instances of a composite have been created and how many have faulted. You can see this in the EM, as shown below Some of these stakeholders may not have knowledge of  EM console and they just want a quick view into the statistics, without having to navigate EM. This post describes how to use the Oracle Fusion Middleware Infrastructure Management Java API  for Oracle SOA Suite (also called the Facade API)  to build a custom ADF page to display this information. If you want a quick introduction in using the Facade API, this post is for you. Read the complete article here.

• Drawing Grid in 3D view - Mathematically calculate points and draw line between them (Not working)

  - by Deukalion

  I'm trying to draw a simple grid from a starting point and expand it to a size. Doing this mathematically and drawing the lines between each point, but since the "DrawPrimitives(LineList)" doesn't work the way it should work, And this method can't even draw lines between four points to create a simple Rectangle, so how does this method work exactly? Some sort of coordinate system: [ ][ ][ ][ ][ ][ ][ ] [ ][2.2][ ][0.2][ ][2.2][ ] [ ][2.1][1.1][ ][1.1][2.1][ ] [ ][2.0][ ][0.0][ ][2.0][ ] [ ][2.1][1.1][ ][1.1][2.1][ ] [ ][2.2][ ][0.2][ ][2.2][ ] [ ][ ][ ][ ][ ][ ][ ] I've checked with my method and it's working as it should. It calculates all the points to form a grid. This way I should be able to create Points where to draw line right? This way, if I supply the method with Size = 2 it starts at 0,0 and works it through all the corners (2,2) on each side. So, I have the positions of each point. How do I draw lines between these? VerticeCount = must be number of Points in this case, right? So, tell me, if I can't supply this method with Point A, Point B, Point C, Point D to draw a four vertice rectangle (Point A - B - C - D) - how do I do it? How do I even begin to understand it? As far as I'm concered, that's a "Line list" or a list of points where to draw lines. Can anyone explain what I'm missing? I wish to do this mathematically so I can create a a custom grid that can be altered.

• would it be bad to put <span> tags within the <head>, for grouping meta data in schema.org format?

  - by hdavis84

  Alright, I'm currently practicing schema.org microdata, and trying to find the best route for every site I build. I have found that i can piggyback itemprops on open graph meta tags. I would like to piggyback more itemprops on opengraph meta tags. However, schema.org requires you to change itemtypes to define all aspects of a "thing". Say I'm defining a LocalBusiness. Open graph has street address, locality, and region i'd like to piggyback on. I'd have to do something like: <html lang="en" itemscope itemtype="http://schema.org/LocalBusiness"> <head> ... <meta itemprop="name" content="Business Name" /> <meta property="og:url" itemprop="url" content="http://example.com" /> <meta property="og:image" itemprop="image" content="http://example.com/logo.png" /> <span itemprop="address" itemscope itemtype="http://schema.org/PostalAddress"> <meta property="og:street-address" itemprop="streetAddress" content="1234 Amazing Rd." /> <meta property="og:locality" itemprop="addressLocality" content="Greenfield" /> <meta property="og:region" itemprop="addressRegion" content="IN" /> </span> </head> Although there's more that can be added in, this is enough of an example to show what I'm trying to achieve. I've searched the web to see if it is an issue to use spans in the head or not, because I don't want invalid markup. I know I can mark up the address information in the body of the pages, but the route above would be more efficient. Does anyone have an answer for this?

• Globacom and mCentric Deploy BDA and NoSQL Database to analyze network traffic 40x faster

  - by Jean-Pierre Dijcks

  In a fast evolving market, speed is of the essence. mCentric and Globacom leveraged Big Data Appliance, Oracle NoSQL Database to save over 35,000 Call-Processing minutes daily and analyze network traffic 40x faster.  Here are some highlights from the profile: Why Oracle “Oracle Big Data Appliance works well for very large amounts of structured and unstructured data. It is the most agile events-storage system for our collect-it-now and analyze-it-later set of business requirements. Moreover, choosing a prebuilt solution drastically reduced implementation time. We got the big data benefits without needing to assemble and tune a custom-built system, and without the hidden costs required to maintain a large number of servers in our data center. A single support license covers both the hardware and the integrated software, and we have one central point of contact for support,” said Sanjib Roy, CTO, Globacom. Implementation Process It took only five days for Oracle partner mCentric to deploy Oracle Big Data Appliance, perform the software install and configuration, certification, and resiliency testing. The entire process—from site planning to phase-I, go-live—was executed in just over ten weeks, well ahead of the four months allocated to complete the project. Oracle partner mCentric leveraged Oracle Advanced Customer Support Services’ implementation methodology to ensure configurations are tailored for peak performance, all patches are applied, and software and communications are consistently tested using proven methodologies and best practices.

• Why is Ubuntu unmounting my primary hard drive?

  - by Twisol

  I'm running Ubuntu 10.10 on my laptop (an Asus G73j), dual-booting Windows 7 if that matters. After using the computer for couple of hours or so, I get a popup complaining that a file was unmounted, then my GNOME desktop panels disappear. I can't save any unsaved work (the file browser shows "Filesystem" as totally empty), and other programs break in odd ways (like Chrome can't browse to any new pages, but keeps current ones going... at least I still have Pandora to listen to when this happens!). I've tried looking in the system logs to no avail; I'm assuming that it can't write any errors to the logs because, of course, the logs are on the primary hard drives. This started happening maybe a few days ago. Yesterday I upgraded from 10.4, but I believe it was happening before then. Any advice for figuring this out? EDIT: It just happened again, and I heard a small little clicky sound from the hard drive about five seconds before things went south. I'm thinking I should start backing up ASAP. In response to a comment, here's the dmesg output: http://askubuntu.pastebin.com/uYGshBay Also, the SMART status says the disk has a few bad sectors, and the detailed data says there are 14. It says it passed the self-assessment though. Lastly, this doesn't seem to be happening when I'm on Windows. I recently re-enabled ureadahead (which I disabled ages ago because it was causing Ubuntu to hang at the startup logo), could that be the source of the problem? I've disabled it again to see.

• Multilingual sites and Google search results, do subfolders really work?

  - by AWinter

  About three months ago we added an English version of our, previously Japanese only, site http://www.clubberia.com under the subfolder http://www.clubberia.com/en/ we've tried to follow the sometimes incomplete best practices laid out by Google by adding alternate tags to all pages that are currently translated. The top page for instance has the following meta tags for language. <link rel="canonical" href="/"> <link rel="alternate" hreflang="ja" href="/"> <link rel="alternate" hreflang="en" href="/en/"> While the English main page under /en/ has <link rel="canonical" href="/en/"> <link rel="alternate" hreflang="ja" href="/"> <link rel="alternate" hreflang="en" href="/en/"> We also have these alternate languages setup in the sitemap. (as per Google's recommendations) http://www.clubberia.com/sitemap.xml It seems however that Google absolutely refuses to show the English top page in results when the user is using English at google.com if you search for "clubberia" you'll, as of this post, get the Japanese description and a title that Google has apparently invented instead of the title and description in the meta-tags for the /en/ index page. Does anyone have any experience with subfolders actually working to affect search results? Am I being too impatient, or possibly doing something incorrect? Should we just give up on subfolders and push to subdomains (not the prettiest option)?
