• Why does my display keep turning off every 10 minutes?

  - by George Edison

  I have installed Ubuntu 11.10 (Oneiric) in VirtualBox as well as virtualbox-guest-additions . The display resolution adapts to the size of the window as expected, but the display turns off after 10 minutes of inactivity. Thinking there was some sort of power management issue at play, I went to Power in the settings dialog: There doesn't really seem to be anything there that mentions "turn off display after xxx minutes" so I assume everything is configured correctly there. Next I went to Screen and found an option there "Turn off after:". Aha! I thought. Now I have found the option - but alas: even after setting it to "never" and restarting multiple times, the display still shuts off after 10 minutes. What am I missing? What option am I overlooking?

• Web-based CMS for mobile app

  - by JWood

  I'm just about to start developing a mobile app which needs to be fed from a CMS. I started designing the tables when I thought there must be something out there which could save me a load of time and let me concentrate on the mobile side of things. So, I'm looking for a CMS that will let me create hierarchical "pages" which will just be 4-5 database fields with a simple front-end to allow to edit and update them. I don't mind having to write some code to layout the database and forms etc, any saving on starting from scratch would be good. The only requirement is that I be able to access the data via some sort of web service, REST, JSON, XML, anything really... Can anyone suggest anything that might help? Thanks, J

• I'm using a shared server, and as such Gmail marks my email as spam (all from headers are different from the same IP)

  - by chipperyman573

  I have a shared server, meaning many people share the same IP. When I send an email, the @website.com is different from someone else that shares the same IP with me, therefore Gmail marks it as spam. For example: My website's IP is 1.2.3.4. My website is mywebsite.com Person 2's website's IP is hosted by the same host, and as such their IP is 1.2.3.4 Person 2's website is person2.com. When they send an email, it gets sent from [email protected] When I send an email, it gets sent from [email protected] According to Gmail's spam thing: "Use the same address in the 'From:' header on every bulk mail you send." Again, the only similarities between our websites is the IP. However, this causes Gmail to mark both our mail as spam. Is there a way to sort this out with Gmail?

• is gnome 3 is slow or my machine?

  - by user103054

  I have Dell XPS 15 i7 - 2360 with nvidia 525M (1GB) with optimus running Ubuntu 12.10 64 bit and have bumblebee installed for optimus. Recently I installed Gnome Shell to give it a try and found it sort of lagging under few scenarios though rest all is butter smooth. When I click on Date gnome 3 it appears as if a second has elapsed before the window is drawn. But others panel items like network or volume looks fine. In gnome 3 when I'm on dash with (window preview) if I remove any of the windows before the remaining windows reshuffle it takes about 2 seconds (noticeable clearly). Everything else is fine in both unity and Gnome Shell. What is causing this slowness? Is Gnome Shell is really slower?

• Configuring Eclipse Xubuntu 12.04

  - by kyng

  Just installed Eclipse 3.7.1 on my xubuntu 12.04. I used to have eclipse installed on my 10.04. You could choose new java project, java source files etc. but this version doesn't have these options. If i make a .java file, it's just plane text, no highlighting and no chance to compile. I have installed eclipse-jdt. I looked https://help.ubuntu.com/community/EclipseIDE this manual. It tells to modify /etc/eclipse/java_home file but there is no such file on my system, just eclipse.ini. Am i missing a step here or have i encountered some sort of a bug?

• Loads wrong resolution when installing

  - by Kevin DB

  I'm trying to install Ubuntu 11.04 from a USB. My computer does load the USB file and I get some sort of BIOS-like screen where I can choose between 'Install from USB' and 'Boot-up from USB'. When I entered the corresponding number my screen resolution is totally messed up. I see that Ubuntu is starting up when I used Boot from USB, but the screen looks the same as you'd have a too high screen resolution. Same story with Install from USB. I can see the screens loading and the menu's and stuff, but not clearly because it load in a too high screen resolution. I'm trying to dual-boot is with Windows XP and max. screen resolution is 800x600.

• 3D Studio Max biped restrictions?

  - by meds

  I have a stock biped character in 3D studio max which has a jump animation. The problem I have with the jump animation is that there is actual y offset happening inside it which makes it awkward to play while the character is jumping since it's not only jumping in the game world but the jump animation is adding its own height offset. I'm tryuing to remove the jump animations height offset, so far I've found the root node and deleted all its key frames which has helped a bit. The problem I'm having now is that the character still has some height offset and if I try to lower it it has a fake 'ground' that isn't at 0 and the limbs sort of bend on the imaginary floor, si there a way to remove this restriction just for the jump animation? Here's what I mean: http://i.imgur.com/qoWIR.png Any idea for a fix? I'm using Unity 3D if that opens any other possibilities...

• Why do large IT projects tend to fail or have big cost/schedule overruns?

  - by Pratik

  I always read about large scale transformation or integration project that are total or almost total disaster. Even if they somehow manage to succeed the cost and schedule blow out is enormous. What is the real reason behind large projects being more prone to failure. Can agile be used in these sort of projects or traditional approach is still the best. One example from Australia is the Queensland Payroll project where they changed test success criteria to deliver the project. See some more failed projects in this SO question Have you got any personal experience to share?

• A record DNS, nameserver help

  - by Josip Gòdly Zirdum

  I just installed kloxo on my vps and I want to link my domain to that server...which it sort of already is...I made it connect to it via an A record. That works, like the IP is pointing to my server but how do I make a website using it. I tried adding the domain but this doesn't work ...I feel i'm not explaining this well um, on my server it asked me to create DNS template so I did I created the nameservers ns1.mydomain.com, ns2.mydomain.com Then I added the domain to the panel mydomain.com I go to the folder it creates to it, but no matter the file there it wont work...any ideas? Is there a way to possibly just not even add a domain to kloxo and just kind of treat the ip of the server as the domain? Since the A record points there anyway? I don't intend to host another website on the server anyway...

• Securely expose WebService from Enterprise Network to Internet Client

  - by hotzen

  Are there any standards (or certified solutions) to expose a (Web-)Service to the internet from a very security-sensitive network (e.g. Banking/Finance)? I am not specifically talking about WS-* or any other transport-layer security á la SSL/TLS, rather about important standards or certifications that must be obeyed. Are there any known products (coming from an SAP-environment) that can provide a "high-security proxy" of some sort to expose specific web-services to the internet? Any buzzwords that a CIO/CTO is aware of about this subject?

• Are there any formalized/mathematical theories of software testing?

  - by Erik Allik

  Googling "software testing theory" only seems to give theories in the soft sense of the word; I have not been able to find anything that would classify as a theory in the mathematical, information theoretical or some other scientific field's sense. What I'm looking for is something that formalizes what testing is, the notions used, what a test case is, the feasibility of testing something, the practicality of testing something, the extent to which something should be tested, formal definition/explanation of code coverage, etc. UPDATE: Also, I'm not sure, intuitively, about the connection between formal verification and what I asked, but there's clearly some sort of connection.

• How do I generate terrain like that of Scorched Earth?

  - by alex

  Hi, I'm a web developer and I am keen to start writing my own games. For familiarity, I've chosen JavaScript and canvas element for now. I want to generate some terrain like that in Scorched Earth. My first attempt made me realise I couldn't just randomise the y value; there had to be some sanity in the peaks and troughs. I have Googled around a bit, but either I can't find something simple enough for me or I am using the wrong keywords. Can you please show me what sort of algorithm I would use to generate something in the example, keeping in mind that I am completely new to games programming (since making Breakout in 2003 with Visual Basic anyway)?

• Could the rel="author" just be a username?

  - by Gkhan14

  I want to use rel="author", however the type of blog I run is about a game, and doesn't relate to my real identity. I'm more known for my screen name, so would this still be okay to use for the rel="author" tag? For example, if my Google+ account is for my user, and not for myself, could I still use it within the rel="author" tag? I don't want to get penalized in any sort of way. My main reason to do this, is to improve click through rate, and just make my blog post sections look better in the searches.

• Visitors have old website cached in their browsers

  - by RussianBlue

  My client's new website is example.com, the old website is example.co.uk. I've re-pointed the A Records to the new website (so as to leave the emails alone) and put in 301 redirects from old pages to new pages. But, my client is upset as he (and he thinks many of his clients) have the old website cached in their browsers and won't know how to clear their browser cache. Is there anything I can do to overcome this and if not, what sort of time will browsers finally stop using their cached pages so I can at least go back to my client and tell him that his clients will finally start to see the new website?

• handling a GET error properly

  - by Andrew Heath

  I have a website that takes two primary get strings: ?type=GAME&id=SomeGameID ?type=SCENARIO&id=SomeScenarioID for reasons unknown, I have recently begun receiving requests for erroneous get strings from both Yandex and Baidu. They are always in the form of: ?type=GAME&id=SomeScenarioID None of my users are triggering these errors, so I am (sort of) confident that this is not due to an HTML template error somewhere on my part. There is also no HTTP_REFER showing up in the $_SERVER array, so I'm guessing these are direct requests from bad dbase data on their part. I see two options for dealing with these bad requests, and would like to know which is recommended... or if there are other, better options I have not thought of: simply 404 the request, since it is incorrect redirect the request to ?type=SCENARIO&id=SomeScenarioID because the scenario IDs are always valid, the breakage is due to asking for the wrong type.

• Collaboration between client, web designer, and web developer

  - by Alex

  I am primarily a Web Developer (back end programming) - but intend to offer a complete service to my clients, from concept, to brand design, photoshop mock-ups and everything else in between. I'm aware that it's a good idea to outsource this design aspect of the project to someone that I trust. My question is more about the process: I imagine that in order for the designer to really grasp what the client wants to create, they would need some sort of interaction. Therefore, does anyone know if it is common to bring both parties into a 3 way discussion? Or is it more common to get all of the info from the client, and then pass it onto the designer, and act as a back and forth middleman? Afterall, I am the designer's client. Any insight into this would be great

• Adjusting the Score on Oracle Text search results

  - by Kyle Hatlestad

  When you sort the results of a search by Score using OracleTextSearch as the search engine in WebCenter Content, the results coming back are based on the relevancy on the document.  In theory, the more relevant the search term is to the document, the higher ranked Score it should receive.  But in practice, the relevancy score can seem somewhat of a mystery.  It's not entirely clear how it ranks the importance of some documents over others based on the search term.  And often times, once a word appears a certain number of times within a document, the Score simply maxes out at 100 and the top results can be difficult to discern from one another.  Take for example the search for 'vacation' on this set of documents:  [Read More]

• Ubuntu touch flashing failed/taking to long. Black screen! Redeploy help!

  - by Marius Rye

  So i'm brand new to the whole unlock, root and flashing thing. I just tried flashing Ubuntu touch on my Galaxy Nexus (international GSM/HSPA+) and everything seamed fine until the very end when i got this ERROR message. ERROR:phablet-flash:Installation is taking too long or an error occured along the way. I didn't know what to do so i disconnected my device (which was in Ubuntu recovery) and tried rebooting it from there, it worked "sort of". i got the Google logo with the unlocked icon then it continued to a black screen. In the installation guide on http://www.ubuntu.com/phone/install said i should: "try wiping the /data partition on your device and redeploy". the problem is that i don't know how to do this and i'm basically sitting here with a useless phone right now. I would be extremely grateful for some proffeexpert help.

• Does Microsoft really offer "support"?

  - by SpashHit

  One of the arguments against using Open Source is that there is no "support". However, do big vendors (e.g. Microsoft) really offer "support" of any kind? I'm sure there is some sort of 4-figure-per-hour "paid support" option out there, but is that really an "option" for any problem short of one that is going to bankrupt your business? To put it more concretely... I buy a Microsoft product... it has a bug... now what? And how is that better than what I get from Open Source?

• How to workaround or diagnose a kernel panic when "safely removing" external hdd?

  - by Shawn

  I'm experiencing an issue when using the "Safely Remove" option to remove my 1TB external HDD from the Unity Launcher. Not every time, but occasionally my screen will go black and display LARGE amounts of text information (which I obviously cannot screen cap). The jist of the info displayed is that unmounting or 'safely removing' the drive causes a kernel panic. Is there a Command Line command to remove mounted drives, or at least one that would show me some sort of error output when the drive is removed? I'm trying to narrow down the cause. I could be imagining this, but it seems to happen most often when I have other programs running when I remove the drive (i.e. Firefox, Transmission). Please note that my external drive is not in use when I attempt to remove it and it is not being used either by Firefox or Transmission at these times. Any help would be appreciated.

• Strategy for building an application to replace a large spreadsheet

  - by Dan Walmsley

  I'm working on an application that is going to replace a rather large spreadsheet. The spreadsheet is used to budget purchases and things like that. It is the largest spreadsheet I have ever seen, and it required a lot of manual data entry, so this application is going to automate much of that. But as I'm working on this I've noticed its slow going. And I got to thinking this must be a common thing to do many companies will start with something like a spreadsheet, then when they get too big to maintain that, they will get a custom application built. So is there anything out there ( a framework or similar ) that does this sort of thing, migrating a spreadsheet to a custom application. I've had a quick Google but not really seen the kind of thing that I'm looking for. It's too late for this project, but I thought it would be worth having a look for next time. How do you guys tackle this problem?

• blurry lines between web application context layer, service layer and data access layer in spring

  - by thenaglecode

  I Originally asked this question in SO but on advice I have moved the question here... I'll admit I'm a spring newbie, but you can correct me if I'm wrong, this one liner looks kinda fishy in a best practices sort of way: @RepositoryRestResource(collectionResourceRel="people"...) public interface PersonRepository extends PagingAndSortingRepository<Person, Long> For those who are unaware, the following does many things: It is an interface definition that can be registered in an application context as a jpa repository, automagically hooking up all the default CRUD operations within a persistence context (that is externally configured). and also configures default controller/request-mapping/handler functionality at the namespace "/people" relative to your configured dispatcher servlet-mapping. Here's my point. I just crossed 3 conceptual layers with one line of code! this feels against my seperation-of-concern instincts but i wanted to hear your opinion. And for the sake of being on a question and answer site, I would like to know whether there is a better way of seperating these different layers - Service, Data, Controllers - whilst maintaining as minimal configuration as possible

One of the more popular monitoring tools, thanks in part to the amount of things beyond just hardware it can monitor, in the comments was Rainmeter. Lee writes: I don’t really monitor my computer constantly, only when something is hanging up and I need to see what’s causing it. That being said, I do have Rainmeter so I can quickly see how much RAM or CPU is being used. For anything more detailed, I just go into the task manager and sort by RAM or CPU.

• Finding Database issue for iphone app

  - by David Liu

  I know this is a dumb question and it might not be "conceptual" but, as a self-starter I really want to know how to get connected to some sort of "commercial database"? I'm recently designing my local gas station utility app for iphone and ipad. I have absolutely no clue of find a relevant database. For example, if I want to make an app for pizza ordering in the great Chicago area. How do I get info (price, menu, location, etc.) of those pizza stores scattered all over Chicago? Can any one light something for me? I appreciated your help. **If this question is not suitable here please tell me and I will delete this post. Thank you.

• Make Offscreen Sliding Content Without Hurting SEO [duplicate]

  - by etangins

  This question already has an answer here: How bad is it to use display: none in CSS? 5 answers On my website I have content which is positioned off the screen, and then slides in when you click a button. For example, when you click the news button, content slides in with news. It didn't occur to me that this might be labeled as a black hat SEO technique, because I have content positioned off the screen with CSS that links elsewhere on my site, and a search engine could very easily interpret that as me hiding content for SEO purposes by positioning it off screen. Obviously, my intention was not to hide content, but was to make a sort of UI/UX content slider where content slides into view when a button is clicked. How can I make something to this effect (where content slides in and out), that would not comprise SEO?
