  • Hosting and scaling of a facebook application on cloud?

    - by DhruvPathak
    We would be building a facebook application in django(Python), but still not sure of where to host it economically,and with a good provision to scale in case the app gets viral. Some details about the app: i) Would be HTML based like a website,using django as a framework. ii) 100K is the number of expected pageviews in a day,if the app is viral. iii) The users will not generate any media content,only some database data will be generated by them. It would be great if someone with more experience can guide on following points: A) Hosting on google app engine or Amazon EC2 or some other cloud like RackSpace : Preferable points found in AppEngine were ease of deployment,cost effectiveness and easy scaling. For EC2: Full hold of the virtual machine,Amazon NoSQL and RDMBS database services in case we decide to use them. B) Does backend technology affect monthly cost ? eg. would CPU and memory usage difference of Django over , for example , PHP framework like CodeIgnitor really make remarkable difference in running costs. ( Here is the article that triggered this thought process : http://journal.dedasys.com/2010/01/12/rough-estimates-of-the-dollar-cost-of-scaling-web-platforms-part-i#comments) C) Does something like Heroku , which provides additional services over Amazon EC2, prove to be better than raw cloud management ? It is not that we are trying for premature scaling, we just want to have a good start so that we are ready to handle unpredicted growth and scale.

  • Bending of track in a racing game

    - by caius
    I am trying to create a small racing game in which the track would be modeled using a BSpline curve for the path's center line and directional vectors to define the 'bending' of the track at each point. My problem is that I don't know how to calculate the correct bending / slope of the curve, in such a way that it would be optimal or at least visually nice for a car to 'bend in the corner'. My idea was to use the direction of the 2nd derivatives of the curve, however while this approach looks fine for most of the track, there are points in which the 2nd derivative makes sharp 'twists' / very quick 180 degree flips. I also read about 'knots' of bsplines, but I don't know if such 'twist' in 2nd derivatives is a knot or knots are something else. Can you tell me that using a BSpline: 1. How could I calculate a visually nice bending of a track for a racing game? 2. Is it possible to do this by using some simple calculations of centripertal force / gravity? 3. Is it possible to do this by using 1st, 2nd and 3rd derivatives of the BSpline curve? I am not looking for the 'physically correct' bending angle for the track, I would just like to create something which is visually pleasing in a simple game. I am using a framework which has a built-in class for BSpline, including support for 1st, 2nd and 3rd derivatives of the curve.

  • Introducing the PeopleSoft Interaction Hub

    - by Matthew Haavisto
    The PeopleSoft Applications Portal has just been re-branded as the PeopleSoft Interaction Hub.  It's not just a name change, however.  As part of our ongoing efforts to deliver a richer user experience to PeopleSoft customers, Oracle/PeopleSoft is now offering an enhanced restricted use license (login required) of the PeopleSoft Interaction Hub free with PeopleTools.  This change extends the existing restricted use license to include the following additional capabilities: Dynamic Unified Navigation.  Enables customers to easily provide seamless, unified navigation among their entire PeopleSoft application portfolio. Site-wide branding.  Makes it easier to brand your ecosystem and provide a vivid, contemporary appearance for your applications. These additions augment the capabilities provided in the previous restricted use license, which remain available: creation and use of collaborative workspaces, and pre-built collaborative services for use in related content.  (See the license notes (login required)for a complete list of everything that is granted with the PeopleTools license.)PeopleSoft is moving to deliver a contemporary user experience for your applications users, and the this license change supports that direction.  In addition, the name change reflects our positioning of the PeopleSoft Interaction Hub as a primary means for unifying your PeopleSoft ecosystem, and providing a richer, web-site-based user experience rather than a pillared, application-based experience.See this white paper to get an idea of some of the capabilities that you can employ with the PeopleSoft Interaction Hub to enhance the PeopleSoft user experience.  In addition, this red paper provides valuable 'how-to' guidance.  In the near future we will be producing a best practices guide for deployment.  In the mean time, the most recent release/feature pack of the PIH automates the setup of unified navigation with a Workcenter specifically supporting Unified Navigation. This Workcenter guides administrators through the setup process, and streamlines things.So what should customers do if they still want to use the PeopleSoft Interaction Hub for traditional portal purposes?  Customers can employ the PIH's full capabilities such as multiple site deployment/management and content management, by buying the full, unrestricted license. We are continuing to enhance the product, and it remains part of Applications Unlimited, and we have some exciting features planned.

  • Photoshop alternative with same keyboard shorcuts

    - by user292254
    tldr; Is there a program with the same keyboard shortcuts and/or user interface as PS. I know the "photoshop alternative" question has been asked so many times, but I feel this variant is worth the time to ask. I am a web designer and have been using PS daily on a windows or mac machine for about 10 years, but I do most of my development in linux. The only thing that has been keeping me from the full switch to linux is PS. I have tried many alternatives, including GIMP, but I feel the barrier to entry is too high for one reason and one reason only, the keyboard shortcuts. Over the years I have become very adept and quick in the use of PS because of keyboard shortcuts and muscle memory. I realize that many shortcuts can be customized, but many actions are just too different from PS. So my question is what programs are out there that are the closest to PS in keyboard shortcuts and interface. I don't care if I have to do a bunch of customization to get it as close as possible, but I just can't take too much time to learn a completely new workflow. Of course I realize that any software will take time and effort, I just want to make that time/effort as minimal as possible. Thanks in advance for your responses. edit I should tell you the most important features and workflow I use on a daily basis are, Smart objects, linked documents, save for web and devises.

  • What tools and knowledge do I need to create an application which generates bespoke automated e-mails? [on hold]

    - by Seraphina
    I'd like some suggestions as to how to best go about creating an application which can generate bespoke automated e-mails- i.e. send a personalized reply to a particular individual, interpreting the context of the message as intelligently as possible... (This is perhaps too big a question to be under one title?) What would be a good starting point? What concepts do I need to know? I'd imagine that the program needs to be able trawl through e-mails as and when they come in, and search for keywords in e-mail content, in order to write an appropriate reply. So there needs to be some form of automated response embedded in the code. Machine learning and databases come to mind here, as I'm aware that google incorporates machine learning already in gmail etc. It is quite tricky to google the above topic, and find the perfect tutorial. But there are some interesting articles and papers out there: Machine Learning in Automated Text Categorization (2002) by Fabrizio Sebastiani , Consiglio Nazionale Delle Ricerche However, this is not exactly a quick start guide. I intend to add to this question, and no doubt other questions will spark off this one. I look forward to suggestions.

  • Setting up multiple cores for apache solr for Ubuntu 12.04 and Drupal 7

    - by chrisjlee
    I'm setting up solr locally for my development purposes and integration with Drupal 7. I'm not very familiar with tomcat. My background has primarily been LAMP setups. So I went and installed the package provided by ubuntu for apache solr following this guide. sudo apt-get install tomcat6 tomcat6-admin tomcat6-common tomcat6-user tomcat6-docs tomcat6-examples sudo apt-get install solr-tomcat I've got that working. The apt-get package manager does a great job and allows me to setup solr but with one core. What steps need to be taken to enable multi core setup for apache solr?

    Over the past year or so I've been writing a lot of How To Guides for different technologies. While we have really excellent product documentation (including the best set of manual pages available on any UNIX or Linux platform), the various How To Guides we have help to complement some of that learning, giving administrators a chance to learn the motivations for different technologies with a simple set of examples. Not only are they fun to research and write, they're also one of the more popular items on our Oracle Solaris 11 technology pages on OTN. So here's a link to bookmark and come back to on a regular basis: Oracle Solaris 11 How To Guides. We've got an excellent line up of articles there, and below is a list of the ones I've been involved in writing.

  • AME : How to Diagnose Issues With the Default Approver List in Purchasing When Using Approvals Management

    - by Oracle_EBS
    Do you need help in understanding the concepts or how to setup the Approval Management Engine (AME) for requisition approvals? See the new diagnostic Note 1437183.1 'AME : How to Diagnose Issues With the Default Approver List in Purchasing When Using Approvals Management'. AME is designed to generate the approval list according to the conditions and rules you define in the setup. This troubleshooting guide will help you understand how AME builds the default approval list for Purchasing and help users find solutions for scenarios where the approval list fails to be generated. Follow along with the logical steps for troubleshooting.  The note first reviews how to generate the AME Setup report.   For example in the note we see a fragment of the setup report. Notice it has different sections for each one of the setup categories including attributes, conditions, rules, action types, approval groups etc.  How the default approval list is built in AME is then reviewed, followed by the logical steps for diagnosing issues.  The diagnostic steps include how to run the Test Workbench, as well as how to obtain valuable debug and exception information.  Then follow along using the steps to build a simple test case to sharpen your understanding.

  • Plugged in, not charging&ndash;Windows 7

    - by Kelly Jones
    Just a quick post on something I ran into lately with my Dell Precision M4500 laptop (monster laptop!).  I noticed the little icon in the system tray for the power options was stating that it was “plugged in, not charging”.  I don’t know why it was stating this, but I quickly found a fix for it on the net. I found the fix in this forum on CNET.  Here’s the fix: In order to correct problems with the battery's power management software, follow the steps below. 1. Click Start and type device in the search field, then select Device Manager . 2. Expand the Batteries category. 3. Under the Batteries category, right-click the Microsoft ACPI Compliant Control Method Battery listing, and select Uninstall . WARNING: Do not remove the Microsoft AC Adapter driver or any other ACPI compliant driver. 4. On the Device Manager taskbar, click Scan for hardware changes . Alternately, select Action > Scan for hardware changes . Windows will scan your computer for hardware that doesn't have drivers installed, and will install the drivers needed to manage your battery's power. The notebook should now indicate that the battery is charging.   And it did work.

  • TraceTune: Improved Comment View

    - by Bill Graziano
    I wanted an easier way to identify queries I’d already looked at so I could skip them.  I’ve been entering comments for each query as I review it.  These comments typically fall into three categories: a change I made, no easy fix available or something needs to be changed on the client.  TraceTune now highlights any statement with a comment in bold.  If you hover over the statement you’ll see the most recent comment for that statement. This gives me a quick way to see what’s new and identify those queries that still need work.  This is especially helpful when I come back to a server after weeks or months away.  These comments help jar my memory and remind me what I’ve worked on. I made the font slightly smaller in some of the tables.  It’s still readable but I’m able to get more of a SQL statement on the screen.  I also got to re-experience the pain of Internet Explorer, Chrome and FireFox all displaying text (and pop-up text) slightly different. Seeing the comments on a trace has been a big help to me.  I often do a round of tuning and then don’t come back to a server until months later.  Having the comments available helps me get back up to speed quickly.

  • How to Structure a Trinary state in DB and Application

    - by ABMagil
    How should I structure, in the DB especially, but also in the application, a trinary state? For instance, I have user feedback records which need to be reviewed before they are presented to the general public. This means a feedback reviewer must see the unreviewed feedback, then approve or reject them. I can think of a couple ways to represent this: Two boolean flags: Seen/Unseen and Approved/Rejected. This is the simplest and probably the smallest database solution (presumably boolean fields are simple bits). The downside is that there are really only three states I care about (unseen/approved/rejected) and this creates four states, including one I don't care about (a record which is seen but not approved or rejected is essentially unseen). String column in the DB with constants/enum in application. Using Rating::APPROVED_STATE within the application and letting it equal whatever it wants in the DB. This is a larger column in the db and I'm concerned about doing string comparisons whenever I need these records. Perhaps mitigatable with an index? Single boolean column, but allow nulls. A true is approved, a false is rejected. A null is unseen. Not sure the pros/cons of this solution. What are the rules I should use to guide my choice? I'm already thinking in terms of DB size and the cost of finding records based on state, as well as the readability of code the ends up using this structure.

  • Amazon Careers website - are resumes processed in plain text format only?

    - by sapphiremirage
    The submission site has the following options: "Please upload your resume (Word Document, max size: 512 KB) OR Please copy and paste the text version of your file here", with a text box below the latter option. I went ahead and uploaded my shiny LaTeX resume (as a PDF), despite the fact that they seem to want a Word Document, and there didn't seem to be any issues. However, when I went back to edit my profile, there was no evidence that my PDF had been uploaded, other than a text version of my resume, awfully formatted and clearly stripped from the PDF, sitting in the text box below "Please copy and paste the text version of your file here". Exasperated, I did a quick and dirty copy of the text from my resume into a Word doc and uploaded that. Same result: no evidence of a file uploaded, just a stripped text version in the textbox. What I'm wondering now is, are they only going to look at the text version of my resume? If that's the case then I'm obviously going to edit it so that it looks halfway decent and doesn't contain such atrocities from the conversion as "Other Skills: LTEX". I can pretty little text files without too much effort, so this isn't that big of deal. However, my LaTeX resume is going to look better than anything I can do in plain text, so if the site is actually keeping a copy of that, then I certainly don't want to override it. Has anyone here either gone through the Amazon hiring process or interviewed candidates and know how this works? (i.e. When on site with Amazon, did the interviewers have diversely formatted resumes, or did they all look suspiciously similar)

  • List all BPM Processes for a user

    - by kasriniv
    Hello, Happy to start contributing to this blog..  The title of the blog is probably deceptively simple and warrants an elaboration. Customized BPM workspaces/user interfaces are a fairly common requirement. One of our marquee customers in the online stock trading business, envisioned this user interaction for their BPM application: User logs in to the internal portal Use will have list of roles which he is granted as a drop down list Once user selects the role, a list of processes which user is part of appear. Logged in user can be part of any swimlane role of the process This can be a fairly common/reasonable user-UI interaction pattern. 1. and 2. are easily achievable and hence the subject matter of this blog is the requirement in 3. Objective: Given a username and a role, list all the BPM processes that the user is part of, in any swimlane of any process. Here is quick overview of the major steps/logic in the code: Intialize workflow/BPM  context as usual Get a handle on InstanceQueryService(getInstanceQueryService), InstanceManagementService,        ProcessMetadataService and ProcessModelService List all Processes for that bpmcontext (listProcessMetadataSumary) and get Granted roles to that user For each of the processes [method  getAccessibleProcesss(ProcessMetadataSummary, Set)]for each of the lanes in the process, check if the role granted to the user, matches the roleName for that swimlane. If so, add to output. Notes: The usual caveats apply including BPM APIs are subject to change.  JDeveloper method introspection is your better friend than API documentation :-)... (I am going to try upload the source code  and if it doesnt work, will follow this blog up with the corresponding source code.) Hope this helps.  Ack: Yogesh K, BPM Dev team.

  • Yelp, Google's API for restaurants help

    - by chris
    Ok I have looked into this, and I'm not sure if anyone else has experience with it. I'm having termendous difficulties with Yelp and Google's API. To help explain what I am trying to do here is the concept of the website. We would have to pull restaurants based on user distance, and then randomize them based on quality of restaurant based on feedback from review websites (Yelp, Google, urbanspoon, zagat, opentable, kudzu, yahoo - doesn't have to be from all), and feedback from our users (on results page for the random restaurant users can select good recommendation/bad recommendation). There’s a lot we could calculate for our formula. Things that will dictate your results will be based on if you’re at home or work. If you’re at home you will have more time to drive out to the city to grab some dinner or lunch. If you’re at work we would have to recommend restaurants nearby as lunch is typically 30 minutes to a hour. A 30 minute lunch would require take out most likely or quick service. A hour lunch break you could dine in at a local fine dining restaurant. So in a nutshell, user comes to website. Select if they're at home or work, click submit and we will have a random restaurant selected for them to go. If they don't like it they can click retry and a new restaurant can show. The issue I am having is using the API to gather all the restaurants in the US. I know it can be done because there are similiar websites/apps that pull restaurants that are closest to you such as Ness, Alfred, and I believe there's two more but I can't remember the names. Anyone know if this can be accomplish?

  • How to create shared home directories across multiple computers?

    - by Joe D
    I know there are ways to share a folder across computers making it easy to move files. But I was wondering how one would setup a single login which lets you access the same files regardless of which machine you login on? What I would like is something similar to something you would see in a college campus where students login on machines in the lab and see their files regardless of which machine they use. I know there are server involved here. I have a need to create this on a smaller scale where we have a few computers available (and one of these could act as the server if needed and host the files) that every one shares. Note, the specific install of software might be different on each computer but the login and OS are the same. Since some computers have additional capability that our group members will need to use at rotating schedules (software licenses or hardware components, etc.). I have not done this before, so I would appreciate detailed instructions if possible or a reference to a guide that describes this. Thanks in advance.

  • In virtualbox, I can't access the dvd drive to install a guest host

    - by user211062
    I have installed a fresh copy of Ubuntu Server 12.04 and VirtualBox 4.3. I have set up a VM called "MediaServer" and tried to start it. I then get the following error: Cannot open host device '/dev/sr0' for readonly access. Check the permissions of that device ('/bin/ls -l /dev/sr0'): Most probably you need to be member of the device group. Make sure that you logout/login after changing the group settings of the current user (VERR_ACCESS_DENIED) I have looked all over the Internet and have been unable to find a solution. Using Webmin, I tried changing the group settings so that my user name was in the "vboxusers" group, but that did not work either. I tried various other changes in group settings and none of them worked. Also, I tried rebooting the server after the changes and that didn't work either. I have been following a guide on how to set up an Ubuntu server from the website "linuxhomeserverguide.com" and when it came to the section where you could finally set up your first virtual machine, I am stumped. I would really appreciate it if someone could help me. Thanks in advance.

  • Faster 2D Collision detection

    - by eShredder
    Recently I've been working on a fast-paced 2d shooter and I came across a mighty problem. Collision detection. Sure, it is working, but it is very slow. My goal is: Have lots of enemies on screen and have them to not touch each other. All of the enemies are chasing the player entity. Most of them have the same speed so sooner or later they all end up taking the same space while chasing the player. This really drops the fun factor since, for the player, it looks like you are being chased by one enemy only. To prevent them to take the same space I added a collision detection (a very basic 2D detection, the only method I know of) which is. Enemy class update method Loop through all enemies (continue; if the loop points at this object) If enemy object intersects with this object Push enemy object away from this enemy object This works fine. As long as I only have <200 enemy entities that is. When I get closer to 300-350 enemy entities my frame rate begins to drop heavily. First I thought it was bad rendering so I removed their draw call. This did not help at all so of course I realised it was the update method. The only heavy part in their update method is this each-enemy-loops-through-every-enemy part. When I get closer to 300 enemies the game does a 90000 (300x300) step itteration. My my~ I'm sure there must be another way to aproach this collision detection. Though I have no idea how. The pages I find is about how to actually do the collision between two objects or how to check collision between an object and a tile. I already know those two things. tl;dr? How do I aproach collision detection between LOTS of entities? Quick edit: If it is to any help, I'm using C# XNA.
