• Ubuntu 13.10, kernel 3.11 blank screen issue with hybrid graphics

  - by Lagerbaer

  On my HP Envy, which has both an Intel on-chip graphics card and an Nvidia Geforce: *-display UNCLAIMED description: 3D controller product: GK208M [GeForce GT 740M] vendor: NVIDIA Corporation physical id: 0 bus info: pci@0000:01:00.0 version: a1 width: 64 bits clock: 33MHz capabilities: cap_list configuration: latency=0 resources: memory:d2000000-d2ffffff memory:a0000000-afffffff memory:b0000000-b1ffffff ioport:5000(size=128) memory:b2000000-b207ffff *-display description: VGA compatible controller product: 4th Gen Core Processor Integrated Graphics Controller vendor: Intel Corporation physical id: 2 bus info: pci@0000:00:02.0 version: 06 width: 64 bits clock: 33MHz capabilities: vga_controller bus_master cap_list rom configuration: driver=i915 latency=0 resources: irq:46 memory:d3000000-d33fffff memory:c0000000-cfffffff ioport:6000(size=64) I have trouble with all newer kernels. I basically had to install 12.04 LTS and use their 3.5 kernel family to get the system to boot. The 3.8 from 12.10 or the newest 3.11 from Ubuntu 13.10 leave me with a black screen upon boot. On one occasion I did hear the "log in" sound, but the screen did not display anything. I have purged all nvidia drivers so I guess it should just use the intel drivers, but apparently this is all messed up with newer kernel versions. This is different from the other "nvidia boots into blank screen" bug in that I don't rely solely on an nvidia card. Surely the intel on-chip card should be supported and leave me with something different from a blank screen? Again, it only works with kernel versions 3.5.0-41-generic, not with the 3.11.0-12 one that ships with Ubuntu 13.10. When I go into the grub menu and change the boot options from 'quiet splash' to 'nomodeset' I am able to boot the system, but then I don't get any graphics and trying 'sudo service lightdm start' doesn't succeed (I get 100% CPU for apport, but this doesn't do anything either, so I kill it). Help, I'm all out of ideas. EDIT: Let me add that I'm using the EFI boot system and have a dual-boot installation with Windows 8.

• Two views of Federation: inside out, and outside in

  - by Darin Pendergraft

  IDM customers that I speak to have spent a lot of time thinking about enterprise SSO - asking your employees to log in to multiple systems, each with distinct hard to guess (translation: hard to remember) passwords that fit the corporate security policy for length and complexity is a strategy that is just begging for a lot of help-desk password reset calls. So forward thinking organizations have implemented SSO for as many systems as possible. With the mix of Enterprise Apps moving to the cloud, it makes sense to continue this SSO strategy by Federating with those cloud apps and services.  Organizations maintain control, since employee access to the externally hosted apps is provided via the enterprise account.  If the employee leaves, their access to the cloud app is terminated when their enterprise account is disabled.  The employees don't have to remember another username and password - so life is good. From the outside in - I am excited about the increasing use of Social Sign-on - or BYOI (Bring your own Identity).  The convenience of single-sign on is extended to customers/users/prospects when organizations enable access to business services using a social ID.  The last thing I want when visiting a website or blog is to create another account.  So using my Google or Twitter ID is a very nice quick way to get access without having to go through a registration process that creates another username/password that I have to try to remember. The convenience of not having to maintain multiple passwords is obvious, whether you are an employee or customer - and the security benefit of not having lots of passwords to lose or forget is there as well. Are enterprises allowing employees to use their personal (social) IDs for enterprise apps?  Not yet, but we are moving in the right direction, and we will get there some day.

• Wireless connection disconnects and reconnects with a Netgear WNA1000

  - by William Berkenkamp

  Ever since I made the permanent switch from Vista to Ubuntu i've had wireless connectivity problems. From watching the network manager when it disconnects it seems like it turns off the receiver for some reason. Could it be bad drivers? I used their install software and the site doesn't really offer driver downloads. The adapter is a Netgear WNA1000 if memory serves, and I don't know much about the router except that it's a Motorola Surfboard.

• Oracle E-Business Products New Search Helpers for Guided Resolution of Customer Issues

  - by user793044

  Oracle E-Business Proactive Support has created many new guided resolution documents that you may find helpful in resolving issues in your EBS applications.  These new documents are called “Search Helpers” and they guide you through your issue to a solution.  They are meant to be an easy and fast method to finding a relevant, complete solution. Hundreds of notes and service requests were reviewed and the best solutions to these known issues were selected.  For some issues, notes were updated to better clarify the solution.  In other cases, if a note with a solution did not already exist, one was created. You start the process by selecting the scenario you have encountered.  You may have received an error message, or there may be a particular area of the application in which you have encountered an issue.  Based on your selection of the issue, the Search Helper will present one or more additional possible symptoms.  When you have selected from both of these two sections, you are then presented with one or more articles known to have fully solved this issue in the past.  Several EBS products have produced Search Helpers documents.  Take a look at Doc ID 1501724.1 for an index of the current EBS Search Helpers.  Here is an example of a Search Helper from the Receivables Transactions area: After selecting the Functional Area of "Entering / Updating Transactions" a list of Known Symptoms is presented: And, when "Transaction numbers are not in sequence" is selected, a solution link is provided for Document ID 197212.1: How To Setup Gapless Document Sequencing in Receivables. The EBS applications that currently have published Search Helpers are: Advanced Pricing Applications Technology Configurator General Ledger Human Capital Management Inventory Management Order Management Payables Process Manufacturing Purchasing Receivables Shipping Value Chain Planning

• Need efficient way to keep enemy from getting hit multiple times by same source

  - by TenFour04

  My game's a simple 2D one, but this probably applies to many types of scenarios. Suppose my player has a sword, or a gun that shoots a projectile that can pass through and hit multiple enemies. While the sword is swinging, there is a duration where I am checking for the sword making contact with any enemy on every frame. But once an enemy is hit by that sword, I don't want him to continue getting hit over and over as the sword follows through. (I do want the sword to continue checking whether it is hitting other enemies.) I've thought of a couple different approaches (below), but they don't seem like good ones to me. I'm looking for a way that doesn't force cross-referencing (I don't want the enemy to have to send a message back to the sword/projectile). And I'd like to avoid generating/resetting multiple array lists with every attack. Each time the sword swings it generates a unique id (maybe by just incrementing a global static long). Every enemy keeps a list of id's of swipes or projectiles that have already hit them, so the enemy knows not to get hurt by something multiple times. Downside is that every enemy may have a big list to compare to. So projectiles and sword swipes would have to broadcast their end-of-life to all enemies and cause a search and remove on every enemy's array list. Seems kind of slow. Each sword swipe or projectile keeps its own list of enemies that it has already hit so it knows not to apply damage. Downsides: Have to generate a new list (probably pull from a pool and clear one) every time a sword is swung or a projectile shot. Also, this breaks down modularity, because now the sword has to send a message to the enemy, and the enemy has to send a message back to the sword. Seems to me that two-way streets like this are a great way to create very difficult-to-find bugs.

• Implementing my Entity System. Questions about some problems I have found.

  - by Notbad

  Hi!, Well during this week I have deciding about implementation of my entity system. It is a big topic so it has been difficult to take one option from the whole. This has been my decision: 1) I don't have an entity class it is just an id. 2) I have systems that contain a list of components (the list is homegenous, I mean, RenderSystem will just have RenderComponents). 3) Compones will be just data. 4) There would be some kind of "entity prototypes" in a manager or something from we will create entity instances.Ideally they will define the type of components it has and initialization data. 5) Prototype code to create an entity (this is from the top of my head): int id=World::getInstance()->createEntity("entity template"); 6) This will notify all systems that a new entity has been created, and if the entity needs a component that the system handles it will add it to the entity. Ok, this are the ideas. Let's see if some can help with the problems: 1) The main problem is this templates that are sent to the systems in creation process to populate the entity with needed components. What would you use, an OR(ed) int?, a list of strings?. 2) How to do initialization for components when the entity has been created? How to store this in the template? I have thought about having a function in the template that is virtual and after entity is created an populated, gets the components and sets initialization values. 3) Don't you think this is a lot of work for just an entity creation?. Sorry for the long post, I have tried to expose my ideas and finding in order other could have a start beside exposing my problems. Thanks in advance, Notbad.

• Best way to protect website application code

  - by Gaz_Edge

  Background I have a web application that I host on my own server. I have clients who use the application as is, but some have asked if they can host the application on their own server. This enables them to have their own URLS rather than mine. The application only forms part of their website so I'm assuming it will not be possible for my server to respond to a direct call to their domain etc To give some examples, i currently have urls like www.mydomain.com/profile, www.mydomain.com/index.php?option=someoption&view=someview&id=1 What my clients' want is www.theirdomian.com/profile, www.theirdomian.com/index.php?option=someoption&view=someview&id=1 etc Question My question is, what is the best way for me to allow them to use their own URLs with my application, without giving them all the backend source code and databases to install on their server? One way I thought would be to create a router.php file that sits on their server. The router then asks my server to output the html. The router modifies all the links etc in the html source and outputs the new html through the clients server. When a link is clicked on the clients site, the router receives the request and modifies the url to get the data from my server etc. Is this an effective way to achieve what I want, or is it way off the mark.

• SD Card only mounted after a reboot

  - by evothur

  Hi everyone. I have a Kingston 2GB MicroSD and I plug it in via an inconix MicroSD Adapter to the internal card reader of my Samsung N210 Netbook with Ubuntu 10.10, but it doesn't show up. Only if I reboot the system when the card's plugged in it shows up. Why does it need a reboot for mounting? sudo fdisk -l gives the output below. But I can only see the drive when I reboot the computer while the card's plugged.

• How do sites avoid SEO issues / legalities with subdomain unique ids?

  - by JM4

  I was looking through a few websites recently and noticed a trend I'm not sure I understand. Sites are creating unique referral URLs for customers in the form of: http://customname.site.com (If somebody were to use http://www.site.com/customname it would function the same way). I can see the sites are using 302 redirects at some point using Google Chrome then doing some sort of htaccess redirect, taking the subdomain name (customname) and applying it as a referral parameter then keeping in session during the entire process. However, there must be thousands of these custom URLs that people are typing in. How are each one of these "subdomains" not treated as separate URLs which in turn are redirected to the same page (in short, generating tons of links all pointing to the same page which Google would normally frown upon)? Additionally, the links also appear on the site themselves as clickable links so I'm not sure how these are not tracked. Similarly, the "unique" url is not indexed or cached in any Google search results. How is this capability handled? It does NOT highlight the referral aspect, but a true example of this is visiting http://sfgiants.com which does a 302 redirect to the much longer proper San Francisco Giants MLB homepage. I am wondering how SFgiants.com is not indexed (assuming that direct shortened link appears on several MLB pages)? 1 - I know these are 302 redirects, I can see this on the sites network flow. 2 - These links do in fact appear on the page itself because in some areas (for example, the bottom of the page may say: send this page to a friend! http://name.site.com/ which in turn would again redirect to something like http://www.site.com?id=name so the id value could be stored in session

  The Super User question "Playing mp3 in quodlibet displays “GStreamer output pipeline could not be initialized” error" is indexed under two URLs in Google: http://superuser.com/questions/651591/playing-mp3-in-quodlibet-displays-gstreamer-output-pipeline-could-not-be-initia http://superuser.com/questions/651591/playing-mp3-in-quodlibet-displays-gstreamer-output-pipeline-could-not-be-initia/652058 The first one is the canonical one; the corresponding rel-canonical is included in both pages: <link rel="canonical" href="http://superuser.com/questions/651591/playing-mp3-in-quodlibet-displays-gstreamer-output-pipeline-could-not-be-initia" /> Google also indexed http://superuser.com/a/652058, which redirects to the answer: http://superuser.com/questions/651591/playing-mp3-in-quodlibet-displays-gstreamer-output-pipeline-could-not-be-initia/652058#652058 Now, the second URL from above is the same as this one minus the fragment #652058. So Google seems to strip the fragment, which results in exactly the same page under another URL (= containing the answer ID /652058 as suffix), and indexes it, too -- despite rel-canonical and duplicate content. Shouldn’t Google recognize this and only index the canonical variant? And what could be the reason why Stack Exchange includes the answer ID in the URL path, and not only in the fragment (resulting in various URL variants for the same page)?

• Designing object oriented programming

  - by Pota Onasys

  Basically, I want to make api calls using an SDK I am writing. I have the following classes: Car CarData (stores input values needed to create a car like model, make, etc) Basically to create a car I do the following: [Car carWithData: cardata onSuccess: successHandler onError: errorHandler] that basically is a factory method that creates instance of Car after making an API call request and populating the new Car class with the response and passes that instance to the successHandler. So "Car" has the above static method to create that car, but also has non-static methods to edit, delete cars (which would make edit, delete API calls to the server) So when the Car create static method passes a new car to the successHandler by doing the following: successHandler([[Car alloc] initWithDictionary: dictionary) The success handler can go ahead and use that new car to do the following: [car update: cardata] [car delete] considering the new car object now has an ID for each car that it can pass to the update and delete API calls. My questions: Do I need a cardata object to store user inputs or can I store them in the car object that would also later store the response from all of the api calls? How can I improve this model? With regards to CarData, note that there might be different inputs for the different API calls. So create function might need to know model, make, etc, but find function might need to know the number of items to find, the limit, the start id, etc.

• How do I list all the relation variables and debug them interactively?

  - by mfisch

  I'm writing a charm that requires a mysql database, I found from looking at other charms that this (below) is how I get the info about the database: user=`relation-get user` password=`relation-get password` mysqlhost=`relation-get private-address` But I just found that from reading the wordpress charm example, is there a way to show all the relation variables that I can use? Also, while debugging my db-relation-changed script, I wanted to ssh into my host and interactively run those commands, for example relation-get user, but it didn't work. I resorted to having to restart everything and use juju log to print them out. This wasted a lot of time. Is there a way to print out these relations, either from my dev box or from the instance running my charm? (Below is what happens when I tried to interactively run relation-get): ubuntu@mfisch-local-tracks-0:~$ relation-get user usage: relation-get [-h] [-o OUTPUT] [-s SOCKET] [--client-id CLIENT_ID] [--format FORMAT] [--log-file FILE] [--log-level CRITICAL|DEBUG|INFO|ERROR|WARNING] [-r RELATION ID] [settings_name] [unit_name] No JUJU_AGENT_SOCKET/-s option found I tried juju debug-hooks tracks/0 -e local, that dropped me into a shell and relation-get still failed.

• Web Applications Desktop Integrator (WebADI) Feature for Install Base Mass Update in 12.1.3

  - by LuciaC

  Purpose The integration of WebADI technology with the Install Base Mass Update function is designed to make creation and update of bulk item instances much easier than in the past. What is it? WebADI is an Excel-based desktop application where users can download an Excel template with item instances pre-populated based on search criteria.  Users can create and update item instances in the Excel sheet and finally upload the Excel data using an "upload" option available in the Excel menu. On upload, the modified data will bulk upload to interface tables which are processed by an asynchronous concurrent program that users can monitor for the uploaded results. Advantage: This allows users to work in a disconnected Environment: session time outs can be avoided, as once a template is downloaded the user can work in a disconnected environment and once all updates are done the new input can be uploaded. Also the data can be saved for later update and upload. For more details review the following: R12.1.3 Install Base WebADI Mass Update Feature (Doc ID 1535936.1) How To Use Install Base WebADI Mass Update Feature In Release 12.1.3 (Doc ID 1536498.1).
