• Oracle India Provides Choices For Students

  - by user769227

  For next year's graduating class of computer science and engineering students, the world is their oyster. I believe that in today's day and age the opportunities for graduates are truly endless. Many students have a misconception that Oracle is mainly a Database Company. While we certainly are leaders in the database space, there is so much more that we do. If you look a little bit deeper you will find we have business groups within Oracle creating technical solutions across all areas of the business world. I think that the opportunities available at Oracle can be those 'life changing' roles that students are looking for where they will learn, develop, be challenged and still have the opportunity to be themselves. What other company provides as many choices for students as Oracle. The range of business and technical solutions we provide is enormous. At Oracle India we hire students across a range of different business groups. Below is a presentation showing you just some of the different business groups that hire graduates in Oracle India. The theme is 'choices' because we believe with the variety of work we do we provide the choice to allow you to be you. .prezi-player { width: 550px; } .prezi-player-links { text-align: center; } Oracle Campus Recruitment India: Choices on Prezi As you can see, here at Oracle you get the chance to allow 'You to be You'. If Cloud Computing is what you are interested in, great explore opportunities in our Cloud Services Team. Have you always wanted to work as a Systems Engineer, maybe a role in our Systems/Hardware Business is right for you.

• How can I transfer a blog hosted on Community Server to WordPress?

  - by Martin Plante

  I have a blog hosted on Community Server 2.1 (old version). I want to transfer it to WordPress (.com). I have tried exporting it to the BlogML format, but it failed with an exception. I saved a copy of the full RSS feed, by setting the # of posts to show to a huge number, save, then lower it back. I have all images and do not mind having to upload and rename them one by one. There must be a way to read that RSS file and either directly import it into WordPress, or for a more complicated path, transform it with the proper XSLT into the BlogML (or other) format, to import it into WordPress?

• Make an object slide around an obstacle

  - by Isaiah

  I have path areas set up in a game I'm making for canvas/html5 and have got it working to keep the player within these areas. I have a function isOut(boundary, x, y) that returns true if the point is outside the boundary. What I do is check only the new position x/y separately with the corresponding old position x/y. Then if each one is out I assign them the past value from the frame before. The old positions are kept in a variable from a closure I made. like this: opos = [x,y];//old position npos = [x,y];//new position if(isOut(bound, npos[0], opos[1])){ npos[0] = opos[0]; //assign it the old x position } if(isOut(bound, opos[0], npos[1])){ npos[1] = opos[1]; //assign it the old y position } It looks nice and works good at certain angles, but if your boundary has diagonal regions it results in jittery motion. What's happening is the y pos exits the area while x doesn't and continues pushing the player to the side, once it has moved the player to the side a bit the player can move forward and then the y exits again and the whole process repeats. Anyone know how I may be able to achieve a smoother slide? I have access to the player's velocity vector, the angle, and the speed(when used with the angle). I can move the play with either angle/speed or x/yvelocities as I've built in backups to translate one to the other if either have been altered manually.

• Unset the system immutable bit in Mac OS X

  - by skylarking

  In theory I believe you can unlock and remove the system immutable bit with: chflags noschg /Path/To/File But how can you do this when you've set the bit as root? I have a file that is locked, and even running this command as root will not work as the operation is not permitted. I tried logging in as Single-User mode to no avail. I seem to remember that even though you are in as root you are in at level '1'. And to be able to remove the system-immutable flag you need to be logged in at level '0'. Does this have something to do with this issue?

• Tracking subdomains in the same profile as the main domain

  - by Osvaldo

  I have a site, let's call it http://www.example.com with a non-universal Google analytics account. Now we have to add new functionalities in a subdomain like https://subdomain.example.com as a micro site. On that subdomain the URL's will be something like https://subdomain.example.com?param1=foo&param2=bar We can't change the requirements as both main site and mini-site use a different CMS/application. This is strictly a Google Analytics question. But we need to count pageviews and events that happen in that subdomain (with URLs like https://subdomain.example.com?param1=foo&param2=bar) as belonging to the main domain. So pageviews and events in https://subdomain.example.com?param1=foo&param2=bar need to be recorded as if they happened in http://www.example.com/path/to/whatever/I/want Fortunately we have full control on JavaScript in the main domain site and in the subdomain site too. How can we make this work? Do we need to change tracking code both in the main domain and subdomains? Do we need to reconfigure Google Analytics? Please note again that we do not want to create a new view for the subdomain. Both mini-site and main site should be in the same account, property and view.

• ARTS Reference Model for Retail

  - by Sanjeev Sharma

  Consider a hypothetical scenario where you have been tasked to set up retail operations for a electronic goods or daily consumables or a luxury brand etc. It is very likely you will be faced with the following questions: What are the essential business capabilities that you must have in place?  What are the essential business activities under-pinning each of the business capabilities, identified in Step 1? What are the set of steps that you need to perform to execute each of the business activities, identified in Step 2? Answers to the above will drive your investments in software and hardware to enable the core retail operations. More importantly, the choices you make in responding to the above questions will several implications in the short-run and in the long-run. In the short-term, you will incur the time and cost of defining your technology requirements, procuring the software/hardware components and getting them up and running. In the long-term, as you grow in operations organically or through M&A, partnerships and franchiser business models  you will invariably need to make more technology investments to manage the greater complexity (scale and scope) of business operations.  "As new software applications, such as time & attendance, labor scheduling, and POS transactions, just to mention a few, are introduced into the store environment, it takes a disproportionate amount of time and effort to integrate them with existing store applications. These integration projects can add up to 50 percent to the time needed to implement a new software application and contribute significantly to the cost of the overall project, particularly if a systems integrator is called in. This has been the reality that all retailers have had to live with over the last two decades. The effect of the environment has not only been to increase costs, but also to limit retailers' ability to implement change and the speed with which they can do so." (excerpt taken from here) Now, one would think a lot of retailers would have already gone through the pain of finding answers to these questions, so why re-invent the wheel? Precisely so, a major effort began almost 17 years ago in the retail industry to make it less expensive and less difficult to deploy new technology in stores and at the retail enterprise level. This effort is called the Association for Retail Technology Standards (ARTS). Without standards such as those defined by ARTS, you would very likely end up experiencing the following: Increased Time and Cost due to resource wastage arising from re-inventing the wheel i.e. re-creating vanilla processes from scratch, and incurring, otherwise avoidable, mistakes and errors by ignoring experience of others Sub-optimal Process Efficiency due to narrow, isolated view of processes thereby ignoring process inter-dependencies i.e. optimizing parts but not the whole, and resulting in lack of transparency and inter-departmental finger-pointing Embracing ARTS standards as a blue-print for establishing or managing or streamlining your retail operations can benefit you in the following ways: Improved Time-to-Market from parity with industry best-practice processes e.g. ARTS, thus avoiding “reinventing the wheel” for common retail processes and focusing more on customizing processes for differentiations, and lowering integration complexity and risk with a standardized vocabulary for exchange between internal and external i.e. partner systems Lower Operating Costs by embracing the ARTS enterprise-wide process reference model for developing and streamlining retail operations holistically instead of a narrow, silo-ed view, and  procuring IT systems in compliance with ARTS thus avoiding IT budget marginalization While parity with industry standards such as ARTS business process model by itself does not create a differentiation, it does however provide a higher starting point for bridging the strategy-execution gap in setting up and improving retail operations.

• "System.Data.OracleClient requires Oracle client software version 8.1.7 or greater." Error Message

  - by Jandost Khoso

  Quick resolution: Give full permission to AUTHENTICATED USERS in following folders. a) ORACLE_HOME b) Program Files\ORACLE   Check your PATH. You might have installed different clients in your system and your .NET application is pointing to a home with inappoperiate client. What your .NET application should load is OCI.DLL with File version more than 8.1.7. According to the MSDN document Oracle and ADO.NET:   "The .NET Framework Data Provider for Oracle provides access to an Oracle database using the Oracle Call Interface (OCI) as provided by Oracle Client software. The functionality of the data provider is designed to be similar to that of the .NET Framework data providers for SQL Server, OLE DB, and ODBC. "     The MSDN document System Requirements (Oracle) says: "The .NET Framework Data Provider for Oracle requires Microsoft Data Access Components (MDAC) version 2.6 or later. MDAC 2.8 SP1 is recommended. You must also have Oracle 8i Release 3 (8.1.7) Client or later installed. "   Both the .NET Framework Data Provider for Oracle and Oracle Data Provider for .NET are data providers to access Oracle database. The former ships with .NET Framework and requires Oracle client version 8.1.7 or above. The latter is provided by Oracle company and requires Oracle client version 9.2 or later.     The Oracle Data Provider for .NET (ODP.NET) features optimized ADO.NET data access to the Oracle database. ODP.NET allows developers to take advantage of advanced Oracle database functionality, including Real Application Clusters, XML DB, and advanced security.   See the document Comparing the Microsoft .NET Framework 1.1 Data Provider for Oracle and the Oracle Data Provider for .NET for more information about the difference.

• My PowerShell functions do not appear to be registered

  - by Frank

  Hi there, I have a ps1 script in which I define 2 functions as such: function Invoke-Sql([string]$query) { Invoke-Sqlcmd -ServerInstance $Server -Database $DB -User $User -Password $Password -Query $query } function Get-Queued { Invoke-Sql "Select * From Comment where AwaitsModeration = 1" } I then call the ps1 file by typing it in (it's in a folder in the path, and autocompletion works) However, I cannot start using the functions. I am confused, because when I copy / paste the functions into the console, all is fine and they work. I also have a function defined in my profile, and it works. Where am I thinking wrong, why doesn't it work what I'm trying to do?

• Enabling mod_fcgid results in 403

  - by laggingreflex

  I have an EasyPHP 12.1 setup (latest) on Windows 7x64 and I'm trying to enable mod_fcgid for PHP. I have added the following in my httpd.conf Include conf/extra/httpd-vhosts.conf LoadModule fcgid_module modules/mod_fcgid.so FcgidInitialEnv PHPRC "C:\progra~2\EasyPHP-12.1\php\php546x121028092509" AddHandler fcgid-script .php FcgidWrapper "C:\progra~2\EasyPHP-12.1\php\php546x121028092509/php-cgi.exe" .php and Options ExecCGI Indexes FollowSymLinks under <Directory "${path}/www"> I've made sure the paths are all good and set permissions on the entire C:\progra~2\EasyPHP-12.1 and my www root to Everyone - Allow All. Yet I still get 403 on all server(localhost) requests. Along with Apache/2.4.2 (Win32) PHP/5.4.6 mod_fcgid/2.3.7 so I know mod_fcgid is enabled and is causing the 403. Commenting out the above lines from httpd.conf makes it work again but is slower than death (which is why I wanted mod_fcgid). What could I be doing wrong?

• Problem with a* implementation in pygame

  - by piyush3dxyz

  Yesterday i decide to make RTS game in pygame(pygame is best).I figured out many components of RTS game like unit selecting,health,resources but only 1 thing i still not understand.. which is a* pathfinding in pygame... I also done little bit of research on wiki,articles and papers...but still cant figure out problem.... function A*(start,goal) closedset := the empty set // The set of nodes already evaluated. openset := {start} // The set of tentative nodes to be evaluated, initially containing the start node came_from := the empty map // The map of navigated nodes. g_score[start] := 0 // Cost from start along best known path. // Estimated total cost from start to goal through y. f_score[start] := g_score[start] + heuristic_cost_estimate(start, goal) while openset is not empty current := the node in openset having the lowest f_score[] value if current = goal return reconstruct_path(came_from, goal) remove current from openset add current to closedset for each neighbor in neighbor_nodes(current) if neighbor in closedset continue tentative_g_score := g_score[current] + dist_between(current,neighbor) if neighbor not in openset or tentative_g_score <= g_score[neighbor] came_from[neighbor] := current g_score[neighbor] := tentative_g_score f_score[neighbor] := g_score[neighbor] + heuristic_cost_estimate(neighbor, goal) if neighbor not in openset add neighbor to openset return failure here is the pseudocode for wiki a* implementation......

• Web Applications under Apache Tomcat with multiple directory contexts

  - by goran

  I have two webapps, prod-1.2.1.war and test-2.0.0.war. If I put these straight into the "tomcat/webapps"-folder, they'll get deployed as; hXXp://localhost/prod-1.2.1/ hXXp://localhost/test-2.0.0/ This works but really I would like them to show up as; hXXp://localhost/vegshop/prod/ hXXp://localhost/vegshop/test/ As you see I somehow would like the "vegshop" to be included in the context path. I also would like the version-numbering to disappear without having to rename the WAR-files. Thank you. This is Apache Tomcat v6.0 under Linux 2.6, running SUN JDK 1.6.

• Player sprite moving slower on iPhone 4

  - by nvillec

  I just finished getting movement/jump animation for a player sprite in Xcode using Cocos2D. The basic movement algorithm is a timer that updates every 0.01 sec, changing the sprite position to (sprite.position.x + xVel, sprite.position.y + yVel). Each time a movement button is tapped, the appropriate velocity (initialized to 0) is changed to whatever speed I choose, then a stop movement button returns the velocity to 0. It's not an ideal solution but I'm very new at this and stoked to at least have that working with little help from the internet. So I may not have explained that perfectly, but it is in fact working to my satisfaction in Xcode's iPhone Simulator, however when I build it for my device and run it on my phone, the sprite's movement speed is noticeably slower than in Xcode. At first I thought it must have to do with the resolution of the iPhone 4, making the sprite's movement path twice as long, but I found that if I pull up the multitask bar, then return to the app the speed will sometimes jump back to normal. My second theory was that the code is just inefficient and is bogging the processes down, but I would see this reflected in the frame rate wouldn't I? It stays at 59-60 the whole time, and the spritesheet animation runs at the correct speed. Has anyone experienced this? Is this a really obvious issue that I'm completely missing? Any help (or tips for optimizing my approach to movement) would be much appreciated!

• Panic Transmit file upload

  - by 1ndivisible

  I've ditched Coda and bought Transmit. I'm a little confused by the file uploading. I have exactly the same folder structure remotely and locally, but if I right-click a file and choose Upload "SomeFileName.html" The file is always uploaded into the root of the remote site, even if the file is in a folder. If I choose to upload a file at assets/images/some_image.png I would expect it to be uploaded to the same folder on the remote server, not the root. Coda dealt with this perfectly and also told me what files had been modified and needed uploading. Transmit doesn't seem to do either of these things. So my questions are: How can I upload a file to the same path on the remote server without having to drag and drop Is there any way to have Transmit mark edited files or upload only edited files. [There is no tag for Transmit so if someone with more rep could make and add one that would be grand]

• Why does cpio say "WARNING! These file names were not selected" when copying a large number of files

  - by mmm bacon

  For over 10 years, I've been using this strategy to copy a large number of files between UNIX filesystems: cd source_directory find . -depth -print | cpio -pdm /path/to/destination_directory It works like a champ. However, I'm now getting this error from cpio: cpio: WARNING! These file names were not selected: (long list of files here...) The source directory is on OSX 10.5, and the destination directory is a NFS filesystem from an OpenSolaris server. Copying over NFS has never been a problem in the past. There's nothing strange about the filenames, meaning there aren't special characters or anything like that. Any ideas?

• Error when installing ubuntu-zfs

  - by ubiquibacon

  I'm switching from FreeNAS to Ubuntu 12.04 LTS. After a vanilla install of Ubuntu has been completed I run the following commands in the order shown to install ZFS: apt-get install python-software-properties add-apt-repository ppa:zfs-native/stable apt-get -y -q update && apt-get -y -q upgrade apt-get install ubuntu-zfs When the last command is run ZFS is installed and seems to be working correctly... mostly (more on that later). However, when the last command is run I get this error (full log here): configure: error: *** Please make sure the kmod spl devel <kernel> package for your *** distribution is installed then try again. If that fails you *** can specify the location of the spl objects with the *** '--with-spl-obj=PATH' option. What is this error and how do I fix it? Now I said mostly earlier because my pool's don't auto mount when the server restarts the way they should. All my reading (mostly from this page) indicates that mountall should just take care of the mounting. I have followed the instructions on that page and I cannot get mountall to work correctly. My pools will only auto mount on restart if I edit /etc/fstab or change the ZFS_MOUNT and ZFS_UNMOUNT options in /etc/default/zfs.

• Outlook 2010: using signatures stored on network

  - by Gregory MOUSSAT

  With Outlook before the 2010 version, it was possible to specify any path for the signatures. With Outlook 2010, the only way is to use those stored into C:\Documents and Setting\UserName\Local Settings\Application Datas\Microsoft\Signature\ I'd like to point the signatures to a network share. Allowing us to modify the signatures into the share, instead of login on every computers each time we are asked to modify them (and this is quite often because the signatures contain logos about current events). We currently use a script to copy the signatures from the share to the local disk when users login. Question: How to set Outlook 2010 to use signatures outside of the default signature folder ?

• Problem inserting pre-ordered values to quadtree

  - by Lucas Corrêa Feijó

  There's this string containing B, W and G (standing for black, white and gray). It defines the pre-ordered path of the quadtree I want to build. I wrote this method for filling the QuadTree class I also wrote but it doesn't work, it inserts correctly until it reaches a point in the algorithm it needs to "return". I use math quadrants convention order for insertion, such as northeast, northwest, southwest and southeast. A quadtree has all it's leafs black or white and all the other nodes gray The node used in the tree is called Node4T and has a char as data and 4 references to other nodes like itself, called, respectively NE, NW, SW, SE. public void insert(char val) { if(root==null) { root = new Node4T(val); } else { insert(root, val); } } public void insert(Node4T n, char c) { if(n.data=='G') // possible to insert { if(n.NE==null) { n.NE = new Node4T(c); return; } else { insert(n.NE,c); } if(n.NW==null) { n.NW = new Node4T(c); return; } else { insert(n.NW,c); } if(n.SW==null) { n.SW = new Node4T(c); return; } else { insert(n.SW,c); } if(n.SE==null) { n.SE = new Node4T(c); return; } else { insert(n.SE,c); } } else // impossible to insert { } } The input "GWGGWBWBGBWBWGWBWBWGGWBWBWGWBWBGBWBWGWWWB" is given a char at a time to the insert method and then the print method is called, pre-ordered, and the result is "GWGGWBWBWBWGWBWBW". How do I make it import the string correctly? Ignore the string reading process, suppose the method is called and it has to do it's job.

• Why don't windows of the same application behave as they should?

  - by Yuttadhammo

  Somewhere along the upgrade path, Unity has developed some strange logic behind window layering. First, before Oneiric, there was a way to see all the windows of an application - I think it was when you click on the icon in the launcher. Now, clicking on the icon often does nothing. Suppose I have two terminals open, one behind this Firefox window, and one in front of it. Clicking on the launcher does nothing - the only way to find the second terminal, afaics, is to move the Firefox window or use the task switcher. Secondly, once I have both terminals on top, then I decide to close one of them, suddenly they both disappear (the second one, for some reason, has gone into hiding behind the Firefox window). Third (though I can't pin it down now), sometimes when a window is on top, focus is still on a window in back; I click on the top x to close the window in front, only to find I've closed an important window in the back. (Update: this question details the problem) I can't really believe these are bugs, since they seem too obvious to not have been fixed by now. My question is, am I missing something? Some compiz option I can set to make it act like it used to? Or is this really how Unity is supposed to act?

• Video game "Gish" will only launch from command line

  - by aberration

  Platform: Lubuntu 11.10 x64 Program: Gish When I try to launch Gish from the command line (/opt/gish/gi.sh), there are no problems. But when I try to launch it from the LXDE menu, it will not start. Contents of /usr/share/applications/gish.desktop: [Desktop Entry] Categories=Game;ActionGame;AdventureGame;ArcadeGame; Exec=/opt/gish/gi.sh Path=/opt/gish Icon=x-gish Terminal=false Type=Application Name=Gish I tried changing Terminal=false to Terminal=true to debug it, but then I just got a blank terminal, and the game didn't start. Edit: Here is some additional information, as requested by Eliah Kagan below: I tried editing /usr/share/applications/gish.desktop, as recommended, but it had no effect However, ~/.xsession-errors contained the following error: [: 8: x86_64: unexpected operator ./gish_32: error while loading shared libraries: libGL.so.1: wrong ELF class: ELFCLASS64 I think there's a problem with the /opt/gish/gi.sh shell script. This is its contents: cd /opt/gish/ MACHINE_TYPE=`uname -m` if [ ${MACHINE_TYPE} == 'x86_64' ]; then ./gish_64 else ./gish_32 fi I'm not too familiar with Bash, so hopefully someone else can point out the error. I have a 64-bit machine. I think that when the script is run from the command line, it's properly launching the 64-bit version (/opt/gish/gish_64), but when it's run from the LXDE menu, it's launching the 32-bit version (/opt/gish/gish_32), which is causing the libGL.so.1 error. However, this may be related to my libGL.so.1 problems with 2 other games.

• Locking down a server for shared internet hosting.

  - by Wil

  Basically I control several servers and I only host either static websites or scripts which I have designed, so I trust them up to a point. However, I have a few customers who want to start using scripts such as Wordpress or many others - and they want full control over their account. I have started to do the basics - like on php.ini, I have locked it down and restricted commands such as proc, however, there is obviously a lot more I can do. right now, using NTFS permissions, I am trying to lock down the server by running Application Pools and individual sites in their own user, however I feel like I am hitting brick walls... (My old question on Server Fault). At the moment, the only route I can think of is either to implement an off the shelf control panel - which will be expensive and quite frankly, over the top, or look at the Microsoft guide - which is really for an entire infrastructure, not for someone who just wants to lock down a few servers. Does anyone have any guides that can put me on the correct path?

• Creating a Sandboxed Instance

  In .NET 4.0 the policy APIs have changed a bit. Here's how you can create a sandboxed instance of a type, which must inherit from MarshalByRefObject: static T CreateRestrictedType<T>(SecurityZone zone, params Assembly [] fullTrustAssemblies) where T : MarshalByRefObject, new() { return(CreateRestrictedType<T>(zone, fullTrustAssemblies, new IPermission [0]); } static T CreateRestrictedType<T>(SecurityZone zone, params IPermission [] additionalPermissions) where T : MarshalByRefObject, new() { return(CreateRestrictedType<T>(zone, new Assembly [0], additionalPermissions); } static T CreateRestrictedType<T>(SecurityZone zone, Assembly [] fullTrustAssemblies, IPermission [] additionalPermissions) where T : MarshalByRefObject, new() { Evidence evidence = new Evidence(); evidence.AddHostEvidence(new Zone(zone)); PermissionSet evidencePermissionSet = SecurityManager.GetStandardSandbox(evidence); foreach (IPermission permission in additionalPermissions ?? new IPermission[ 0 ]) { evidencePermissionSet.AddPermission(permission); } StrongName [] strongNames = (fullTrustAssemblies ?? new Assembly[0]).Select(a = a.Evidence.GetHostEvidence<StrongName>()).ToArray(); AppDomainSetup adSetup = new AppDomainSetup(); adSetup.ApplicationBase = Path.GetDirectoryName(typeof(T).Assembly.Location); AppDomain newDomain = AppDomain.CreateDomain("Sandbox", evidence, adSetup, evidencePermissionSet, strongNames); ObjectHandle handle = Activator.CreateInstanceFrom(newDomain, typeof(T).Assembly.ManifestModule.FullyQualifiedName, typeof(T).FullName); return (handle.Unwrap() as T); } SyntaxHighlighter.config.clipboardSwf = 'http://alexgorbatchev.com/pub/sh/2.0.320/scripts/clipboard.swf'; SyntaxHighlighter.brushes.CSharp.aliases = ['c#', 'c-sharp', 'csharp']; SyntaxHighlighter.all();

• Interpolation between two 3D points?

  - by meds

  I'm working with some splines which define a path a character follows (you can see a gameplay video here to get a better understanding of what's going on: http://www.youtube.com/watch?v=BndobjOiZ6g). Basically the characters 'forward' look direction is set to the 'forward' direction of the spline and when players tilt their phone left and right the character is strafed along its 'right' coordinate. The issue with this is (rather obviously) in performance, interpolating over a spline to find the nearest position and tangent relative to the player is an incredibly costly operation. To get by this I cache a finite number of positions in what I call 'SplineDetails', the class is as follows: public class SplineDetails { public SplineDetails() { Forward = Vector3.forward; Position = Vector3.one * float.MaxValue; Alpha = -1; } public float Alpha; // [0,1] measured along length of spline where 0 is the initial point and 1 is the end point of the spline public Vector3 Position; // the point of the spline at this alpha public Vector3 Forward; // the forward tangent of the spline at this alpha } I populate this with say 30 coordinates and I can give a rough estimate of a coordinate and 'forward' based on a position past in. It's not as accurate but it's much faster. But now I'd like to make the system work better by estimating positions and 'forward' directions by interpolating between two of the cached points though I'm stuck trying to figure out some logic. My first problem is, how can I determine between which two points the object is? Given each point can be placed at different intervals along the spline it could mean that two points in front or behind the object can be closer to the object. The other problem is to figure out the proportion between the two paths it's between, i.e. if there is a point a at coordinate (0,0,0) and point b at coordinate (1,0,0) if the object is at position (0.5,0,0) then the result it should give is '0.5' (as it is equal distance away from point a and point b). That's a simple example, but what if the object is at coordinate (0.5,3,0) for example?

• Where Twitter Stands Heading Into 2013

  - by Mike Stiles

  As Twitter continued throughout 2012 to be a stage on which global politics and culture played itself out, the company itself underwent some adjustments that give us a good indication of what users and brands can expect from the platform in 2013. The power of the network did anything but fade. Celebrities continued to use it to connect one-on-one. Even the Pope signed on this year. It continued to fuel revolutions. It played an exponentially large factor in this US Presidential election. And around the world, the freedom to speak was challenged as users were fired, sued, sometimes even jailed for their tweets. Expect more of the same in 2013, as Twitter has entrenched itself, for individuals, causes and brands, as the fastest, easiest, most efficient way to message the masses so some measure of impact can come from it. It’s changed everything, and it’s not finished. These fun facts reveal the position of strength with which Twitter enters 2013: It now generates a billion tweets every 2.5 days It has 500 million+ users The average Twitter user has tweeted 307 times 32% of everyone using the Internet uses Twitter It’s expected to bring in $540 million in ad revenue by 2014 11 new accounts are created every second High-level Executive Summary: people love it, people use it, and they’re going to keep loving and using it. Whether or not outside developers love it is a different matter. 2012 marked a shift from welcoming the third party support that played at least some role in Twitter being so warmly embraced, to discouraging anything that replicates what Twitter can do itself…or plans to do itself. It’s not the open playground it once was. Now Twitter must spend 2013 proving it can innovate in-house and keep us just as entranced. Likewise, Twitter is distancing itself from Facebook. Images from the #1 platform’s Instagram don’t work on Twitter anymore, and Twitter’s rolling out their own photo filter product. Where the two have lived in a “plenty of room for everybody” symbiosis up to now, 2013 could see the giants ramping up a full-on rivalry. Twitter is exhibiting a deliberate strategy. Updates have centered on more visually appealing search results, and making finding and sharing content easier. Deals have been cut with some media entities so their content stands out. CEO Dick Costolo has said tweets aren’t the attraction, they’re what leads you to content. Twitter aims to be a key distributor of media and info. Add the addition of former News Corp. President Peter Chernin to the board, and their hashtag landing page experience for events, and their media behemoth ambitions get pretty clear. There are challenges ahead and Costolo has also laid those out; entry into China, figuring out how to have Twitter deliver both comprehensive and relevant, targeted experiences, and the visualization of big data. What does this mean for corporations? They can expect a more media-rich evolution and growing emphases on imagery. They can expect more opportunities to create great media content and leverage Twitter for its distribution. And they can expect new ways to surface in searches. Are brands diving in? 56% of customer tweets to companies get completely and totally ignored. Ugh. A study Twitter recently conducted with Compete shows people who see tweets from retailers are more likely to buy a product. And, the more retailer tweets they see, the more likely they are to purchase on the retail site. As more of those tweets point to engaging media content from the brand, the results should get even better. Twitter appears ready for 2013. Enterprise brands have some work to do. @mikestilesPhoto Stuart Miles, freedigitalphotos.net

• Frustrated with MythTV 0.26

  - by Mike

  I've been using MythTV for a while now. Until a hardware crash I had a 0.25 box running without problems. Had to get new hardware and am now in the process of setting up 0.26. Every time I pick a menu option, it hangs for 1 minute. Every time I try to start the backend, same thing. I pick a new theme in the frontend, but it never gets used. I try to test audio, but all I get is static (from the proper channels though). I've setup the storage groups in the backend and put a video in /storage/videos but the front end won't see it when I scan for changes. I make changes in the front end configuration and they don't get saved (or get lost randomly 2-3 reloads later). Obviously there is something I am doing catastrophically wrong, but I have no idea what. Are the storage groups not working yet? Maybe I need to delete all the storage group entries and just use the front end override to set the path? I'm currently using lvm across 3 hard disks, and this has worked well for me in the past. I'd like to use storage groups, but frankly I don't see them working yet at all - especially not for videos (which is what we watch 99% of the time). Anyone have any suggestions for me to try before I just call 0.26 bad names and wipe the system?
