• Hostapd - WLAN as AP

• Video stutter when using external drive

  - by psion

  When using boxee to play video files off of an external western digital 1TB drive formatted NTFS, I notice a slight stutter in the video every 5-10 seconds. When using mplayer, it doesn't stutter as often, but it still stutters occasionally. If I play the video off of the local sata drive, it plays fine even in boxee. I use this computer as my HTPC and I just switched from windows to linux on it. In windows, I never had any sort of stutter playing movies from the drive. I am using the latest intel graphics drivers (for the intel GMA 950) root@eee-htpc:/home/htpc# grep wd /etc/mtab /dev/sdb1 /mnt/wd2 fuseblk rw,nosuid,nodev,allow_other,blksize=512 0 0 I notice that despite trying to use ntfs or ntfs-3g, ubuntu uses ntfs-fuse which I've heard is slower. /dev/sdb1: Timing buffered disk reads: 80 MB in 3.07 seconds = 26.08 MB/sec root@eee-htpc:/mnt/wd2# dd if=/dev/zero of=./120mb bs=1024 count=120000 root@eee-htpc:/mnt/wd2# time mv ./120mb /home/htpc real 0m2.095s user 0m0.016s sys 0m0.736s Even though fuse has a reputation for being slow, it should easily be fast enough for playing standard definition video files. So why the video stutter? edit: The issue seems to be overhead cpu usage from either playing off of a usb device or ntfs/fuse. Watching CPU usage with top, local files use 10-40% CPU. Watching the same video on the external formatted ntfs, it spikes to 170% (over 100% because of hyperthreading). To me it seems like it must be overhead from the fuse driver, though I don't know if it has more or less overhead than ntfs-3g. It's a EEEBox B202 that has an atom 270, so not exactly the most powerful out there. edit2: I believe the solution would be to use non-fuse drivers or different fuse drivers. so far I have not been able to. edit3: I've probably edited this more times than I should, but as an update I have upgraded ntfs drivers to ntfs-3g 2010.8.8 external FUSE 28 - Third Generation NTFS Driver using the following PPA - ppa:x3lectric/team-iquik-releases. When first opening a video file in boxee that's on ntfs there's still the same amount of lag. After a few minutes of video, the lag seems to go away and the cpu usage comes down to 10-40%. Every so often though, it begins to stutter again. Also, if I skip ahead/back in the file, it begins to stutter a lot.

• Leading an offshore team

  - by Chuck Conway

  I'm in a position where I am leading two teams of 4. Both teams are located in India. I am on the west coast of the U.S. I'm finding leading remote teams challenging: First, their command of the English language is weak. Second, I'm having difficultly understanding them through their accents. Third is timing, we are 12 hours apart. We use Skype to communicate. I have a month to get the project done. We've burned through a week just setting up the environments. At this point I'm considering working their hours, 11p PDT to 7a PDT, to get them up to speed, so that I can get the project off the ground. A 12 hour lag time is too much. I'm looking for steps I can take to be successful at leading an offshore team. Update The offshore team's primary task is coding, of course, most coding tasks do involve some design work. The offshore team's are composed of one lead, 2 mid level (4 to 5 years) developers and a junior (~2 years) developer. The project is classic waterfall. We've handed the offshore team a business and a technical design document. We are trying to manage the offshore in an agile way. We have daily conference calls with them and I'm requiring the teams to send me a daily scrum in the form of an email answering the following questions: What did I do today? What am I going to do tomorrow? What do I need from Chuck so I can do my job tomorrow? There is some ambiguity in the tasks. The intent was to give them enough direction for them to develop the task with out writing the code for them. I don't have a travel budget. I am using Fogbugz to track the tasks. Each task has been entered into Fogbugz and given a priority. Each team member has access to FogBugz and can choose what task they wish to complete. Related question: What can we do to improve the way outsourcing/offshoring works? Update 2 I've decided that I can not talk to the team once a day. I must work with them. Starting tonight I've started working the same hours they are. This makes me available to them when they have questions. It also allows me to gain their trust and respect.

• A Slice of Raspberry Pi

  - by Phil Factor

  Guest editorial for the ITPro/SysAdmin newsletter The Raspberry Pi Foundation has done a superb design job on their new $35 network-enabled Linux computer. This tiny machine, incorporating an ARM processor on a Broadcom BCM2835 multimedia chip, aims to put the fun back into learning computing. The public response has been overwhelmingly positive.Note that aim: "…to put the fun back". Education in Information Technology is in dire straits. It always has been, but seems to have deteriorated further still, even in the face of improved provision of equipment.In many countries, the government controls the curriculum. It predicted a shortage in office-based IT skills, and so geared the ICT curriculum toward mind-numbing training in word-processing and spreadsheet skills. Instead, the shortage has turned out to be in people with an engineering-mindset, who can solve problems with whatever technologies are available and learn new techniques quickly, in a rapidly-changing field.In retrospect, the assumption that specific training was required rather than an education was an idiotic response to the arrival of mainstream information technology. As a result, ICT became a disaster area, which discouraged a generation of youngsters from a career in IT, and thereby led directly to the shortage of people with the skills that are required to exploit the potential of Information Technology..Raspberry Pi aims to reverse the trend. This is a rig that is geared to fast graphics in high resolution. It is no toy. It should be a superb games machine. However, the use of Fedora, Debian, or Arch Linux ARM shows the more serious educational intent behind the Foundation's work. It looks like it will even do some office work too!So, get hold of any power supply that provides a 5VDC source at the required 700mA; an old Blackberry charger will do or, alternatively, it will run off four AA cells. You'll need a USB hub to support the mouse and keyboard, and maybe a hard drive. You'll want a DVI monitor (with audio out) or TV (sound and video). You'll also need to be able to cope with wired Ethernet 10/100, if you want networking.With this lot assembled, stick the paraphernalia on the back of the HDTV with Blu Tack, get a nice keyboard, and you have a classy Linux-based home computer. The major cost is in the T.V and the keyboard. If you're not already writing software for this platform, then maybe, at a time when some countries are talking of orders in the millions, you should consider it.

• Push back rectangle where collision happens

  - by Tifa

  I have a tile collision on a game I am creating but the problem is once a collision happens for example a collision happens in right side my sprite cant move to up and bottom :( thats because i set the speed to 0. I thinks its wrong. here is my code: int startX, startY, endX, endY; float pushx = 0,pushy = 0; // move player if(Gdx.input.isKeyPressed(Input.Keys.LEFT)){ dx=-1; currentWalk = leftWalk; } if(Gdx.input.isKeyPressed(Input.Keys.RIGHT)){ dx=1; currentWalk = rightWalk; } if(Gdx.input.isKeyPressed(Input.Keys.DOWN)){ dy=-1; currentWalk = downWalk; } if(Gdx.input.isKeyPressed(Input.Keys.UP)){ dy=1; currentWalk = upWalk; } sr.setProjectionMatrix(camera.combined); sr.begin(ShapeRenderer.ShapeType.Line); Rectangle koalaRect = rectPool.obtain(); koalaRect.set(player.getX(), player.getY(), pw, ph /2 ); float oldX = player.getX(), oldY = player.getY(); // THIS LINE WAS ADDED player.setXY(player.getX() + dx * Gdx.graphics.getDeltaTime() * 4f, player.getY() + dy * Gdx.graphics.getDeltaTime() * 4f); // THIS LINE WAS MOVED HERE FROM DOWN BELOW if(dx> 0) { startX = endX = (int)(player.getX() + pw); } else { startX = endX = (int)(player.getX() ); } startY = (int)(player.getY()); endY = (int)(player.getY() + ph); getTiles(startX, startY, endX, endY, tiles); for(Rectangle tile: tiles) { sr.rect(tile.x,tile.y,tile.getWidth(),tile.getHeight()); if(koalaRect.overlaps(tile)) { //dx = 0; player.setX(oldX); // THIS LINE CHANGED Gdx.app.log("x","hit " + player.getX() + " " + oldX); break; } } if(dy > 0) { startY = endY = (int)(player.getY() + ph ); } else { startY = endY = (int)(player.getY() ); } startX = (int)(player.getX()); endX = (int)(player.getX() + pw); getTiles(startX, startY, endX, endY, tiles); for(Rectangle tile: tiles) { if(koalaRect.overlaps(tile)) { //dy = 0; player.setY(oldY); // THIS LINE CHANGED //Gdx.app.log("y","hit" + player.getY() + " " + oldY); break; } } sr.rect(koalaRect.x,koalaRect.y,koalaRect.getWidth(),koalaRect.getHeight() / 2); sr.setColor(Color.GREEN); sr.end(); I want to push back the sprite when a collision happens but i have no idea how :D pls help

• Box2D Bicycle Wheels Motor Problem - Flash 2.1a

  - by Craig

  I have made a bicycle with Box2D using several polygons for the frame at different angles connected using weld joints, and I have revolute joints on the wheels with a motor. I have made some basic terrain (straight ground and a small ramp) and added keyboard input to control the bicycle with torque to balance it. All of this is done in with Box2D's Debug Draw. When the bicycle is on its back wheel but diagonally forward (kinda like this position - /) the motors just cause it go spinning backwards over when in reality it should either stay on its back wheel or go down onto both wheels. Here's my code the revolute joints: //Front Wheel Joint var frontWheelJointDef:b2RevoluteJointDef = new b2RevoluteJointDef(); frontWheelJointDef.Initialize(frontWheelBody, secondFrameBody, frontWheelBody.GetWorldCenter()); frontWheelJointDef.enableMotor=true; frontWheelJointDef.maxMotorTorque=10000; frontWheelJoint = _world.CreateJoint(frontWheelJointDef) as b2RevoluteJoint; //Rear Wheel Joint var rearWheelJointDef:b2RevoluteJointDef = new b2RevoluteJointDef(); rearWheelJointDef.Initialize(rearWheelBody, firstFrameBody, rearWheelBody.GetWorldCenter()); rearWheelJointDef.enableMotor=true; rearWheelJointDef.maxMotorTorque=10000; rearWheelJoint = _world.CreateJoint(rearWheelJointDef) as b2RevoluteJoint; And here's the relevant part of my update function: // up and down control wheels motor if (up) { motorSpeed-=0.5; } if (down) { motorSpeed += 0.5; } // left and right control cart torque if (left) { middleCentreFrameBody.ApplyTorque( -3); gearBody.ApplyTorque( -3); firstFrameBody.ApplyTorque( -3); secondFrameBody.ApplyTorque( -3); rearWheelToChainBody.ApplyTorque( -3); chainToFrontFrameBody.ApplyTorque( -3); topMiddleFrameBody.ApplyTorque( -3); } if (right) { middleCentreFrameBody.ApplyTorque( 3); gearBody.ApplyTorque( 3); firstFrameBody.ApplyTorque( 3); secondFrameBody.ApplyTorque( 3); rearWheelToChainBody.ApplyTorque( 3); chainToFrontFrameBody.ApplyTorque( 3); topMiddleFrameBody.ApplyTorque( 3); } // motor friction motorSpeed*=0.99; // motor max speed if (motorSpeed>100) { motorSpeed=100; } rearWheelJoint.SetMotorSpeed(motorSpeed); frontWheelJoint.SetMotorSpeed(motorSpeed); Any ideas what might be causing this? Thanks

• Launch 2010 Technical Readiness Unofficial Q&amp;A.

  - by mbcrump

  I had an email from one of my readers about the 2010 Technical Readiness Series. Please read below: Hi Michael, I noticed you blogged a while back that you were going to attend MS 2010 Launch event. I’m going to the session in Seattle on May 27, is it worth it to attend? Also, I’m wondering if they give any free software away like VS2010 Pro? Any decent vendors? Looking forward to hearing back from you. I decided this information would probably benefit several instead of just responding back to the reader. In case you are not aware, MS has a 2010 launch event showing VS2010, Office 2010, SharePoint 2010 and SQL Server 2008R2.  You can sign up for an event here: https://microsoft.crgevents.com/Register2010/Content/Event_Selection.aspx I’ve answered the questions asked below. Q: Is it worth going? A: It is if you have had little or no exposure to the latest 2010 products. Most people are familiar with VS2010, but have not seen SharePoint 2010 Office 2010 or Windows Phone 7. It is designed to get you up to speed very quickly. If you have watched most of the MIX videos and keep up with .NET in general, you will benefit more by having the ability to ask questions.    Q: Did you get any free software? A: No, only demos including: VS2010/Office 2010 – They give you a link to the url where you can download the trial version. Windows 7 Enterprise – You get a DVD with the trial version loaded. Q: Do they give away any cool swag? A: Just a Microsoft T-Shirt (XL). Q: What about the vendor selection? A: At the event that I went to, most vendors were pushing SharePoint products. There wasn’t a lot of variety in the selection. Most vendors were giving away the typical pens, buttons and stickers and trial software. If you have any other questions, feel free to contact me. I will answer and add to this un-official FAQ.

   IDG News Service - Oracle CEO Larry Ellison said Oracle will continue to bet on selling high-end custom hardware for its software products, even amidst a growing trend toward roomfuls of cheap, generic servers. "You have to be in the hardware business and the software business, to get the best possible system," he said during a keynote speech at Oracle's OpenWorld conference in Tokyo. "We believe it's the right idea, we believe it's the next generation of computing, we believe all the pieces have to fit together." Ellison, as he has often done in the past, repeatedly referred to Apple as his "favorite example" of such tight integration. He was a close friend of Apple's co-founder Steve Jobs and previously served on Apple's board of directors.He said sales of Oracle's advanced servers were booming and generating around a billion dollars a year in revenue for the company, which has until recent years focused almost exclusively on its software offerings. With the explosion of popular online services and the increasing number of mobile devices that access them, demand is high for databases that can quickly respond to high numbers of relatively simple queries. While Oracle is pitching its expensive, finely-tuned machines to meet this requirement, Internet behemoths like Google, Facebook and Microsoft increasingly rely on armies of low-cost, easily replaceable servers. Ellison emphasized the high specifications of Oracle's servers, which come packed with multiple terabytes of RAM and flash-based storage for speed. Such machines are superior to large server farms, he said, because they require far less electricity and floor space, and are also cost competitive. When asked about whether purchasing such products would lock customers in to expensive hardware from Oracle, he promised that the company's software would always run on "multiple hardware sources."  Ellison, who spoke from Kyoto, Japan's ancient capital, was shown live online via webcast. The Oracle founder has a fondness for Japanese architecture and is staying in his large garden residence in the city Source: Ellison: Hardware-software integration key, Apple is best example. Oracle's founder and CEO reaffirmed his commitment to custom hardware for its software products  LINK to Computerworld article Apr 5, 2012 http://www.computerworld.com/s/article/9225858/Ellison_Hardware_software_integration_key_Apple_is_best_example?source=CTWNLE_nlt_entsoft_2012-04-09&utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+computerworld%2Fs%2Ffeed%2Ftopic%2F173+%28Computerworld+Databases+News%29#disqus_thread

• Design pattern for an ASP.NET project using Entity Framework

  - by MPelletier

  I'm building a website in ASP.NET (Web Forms) on top of an engine with business rules (which basically resides in a separate DLL), connected to a database mapped with Entity Framework (in a 3rd, separate project). I designed the Engine first, which has an Entity Framework context, and then went on to work on the website, which presents various reports. I believe I made a terrible design mistake in that the website has its own context (which sounded normal at first). I present this mockup of the engine and a report page's code behind: Engine (in separate DLL): public Engine { DatabaseEntities _engineContext; public Engine() { // Connection string and procedure managed in DB layer _engineContext = DatabaseEntities.Connect(); } public ChangeSomeEntity(SomeEntity someEntity, int newValue) { //Suppose there's some validation too, non trivial stuff SomeEntity.Value = newValue; _engineContext.SaveChanges(); } } And report: public partial class MyReport : Page { Engine _engine; DatabaseEntities _webpageContext; public MyReport() { _engine = new Engine(); _databaseContext = DatabaseEntities.Connect(); } public void ChangeSomeEntityButton_Clicked(object sender, EventArgs e) { SomeEntity someEntity; //Wrong way: //Get the entity from the webpage context someEntity = _webpageContext.SomeEntities.Single(s => s.Id == SomeEntityId); //Send the entity from _webpageContext to the engine _engine.ChangeSomeEntity(someEntity, SomeEntityNewValue); // <- oops, conflict of context //Right(?) way: //Get the entity from the engine context someEntity = _engine.GetSomeEntity(SomeEntityId); //undefined above //Send the entity from the engine's context to the engine _engine.ChangeSomeEntity(someEntity, SomeEntityNewValue); // <- oops, conflict of context } } Because the webpage has its own context, giving the Engine an entity from a different context will cause an error. I happen to know not to do that, to only give the Engine entities from its own context. But this is a very error-prone design. I see the error of my ways now. I just don't know the right path. I'm considering: Creating the connection in the Engine and passing it off to the webpage. Always instantiate an Engine, make its context accessible from a property, sharing it. Possible problems: other conflicts? Slow? Concurrency issues if I want to expand to AJAX? Creating the connection from the webpage and passing it off to the Engine (I believe that's dependency injection?) Only talking through ID's. Creates redundancy, not always practical, sounds archaic. But at the same time, I already recuperate stuff from the page as ID's that I need to fetch anyways. What would be best compromise here for safety, ease-of-use and understanding, stability, and speed?

• Is there a better term than "smoothness" or "granularity" to describe this language feature?

  - by Chris

  One of the best things about programming is the abundance of different languages. There are general purpose languages like C++ and Java, as well as little languages like XSLT and AWK. When comparing languages, people often use things like speed, power, expressiveness, and portability as the important distinguishing features. There is one characteristic of languages I consider to be important that, so far, I haven't heard [or been able to come up with] a good term for: how well a language scales from writing tiny programs to writing huge programs. Some languages make it easy and painless to write programs that only require a few lines of code, e.g. task automation. But those languages often don't have enough power to solve large problems, e.g. GUI programming. Conversely, languages that are powerful enough for big problems often require far too much overhead for small problems. This characteristic is important because problems that look small at first frequently grow in scope in unexpected ways. If a programmer chooses a language appropriate only for small tasks, scope changes can require rewriting code from scratch in a new language. And if the programmer chooses a language with lots of overhead and friction to solve a problem that stays small, it will be harder for other people to use and understand than necessary. Rewriting code that works fine is the single most wasteful thing a programmer can do with their time, but using a bazooka to kill a mosquito instead of a flyswatter isn't good either. Here are some of the ways this characteristic presents itself. Can be used interactively - there is some environment where programmers can enter commands one by one Requires no more than one file - neither project files nor makefiles are required for running in batch mode Can easily split code across multiple files - files can refeence each other, or there is some support for modules Has good support for data structures - supports structures like arrays, lists, and especially classes Supports a wide variety of features - features like networking, serialization, XML, and database connectivity are supported by standard libraries Here's my take on how C#, Python, and shell scripting measure up. Python scores highest. Feature C# Python shell scripting --------------- --------- --------- --------------- Interactive poor strong strong One file poor strong strong Multiple files strong strong moderate Data structures strong strong poor Features strong strong strong Is there a term that captures this idea? If not, what term should I use? Here are some candidates. Scalability - already used to decribe language performance, so it's not a good idea to overload it in the context of language syntax Granularity - expresses the idea of being good just for big tasks versus being good for big and small tasks, but doesn't express anything about data structures Smoothness - expresses the idea of low friction, but doesn't express anything about strength of data structures or features Note: Some of these properties are more correctly described as belonging to a compiler or IDE than the language itself. Please consider these tools collectively as the language environment. My question is about how easy or difficult languages are to use, which depends on the environment as well as the language.

• Is there an appropriate coding style for implementing an algorithm during an interview?

  - by GlenPeterson

  I failed an interview question in C years ago about converting hex to decimal by not exploiting the ASCII table if (inputDigitByte > 9) hex = inputDigitByte - 'a'. The rise of Unicode has made this question pretty silly, but the point was that the interviewer valued raw execution speed above readability and error handling. They tell you to review algorithms textbooks to prepare for these interviews, yet these same textbooks tend to favor the implementation with the fewest lines of code, even if it has to rely on magic numbers (like "infinity") and a slower, more memory-intensive implementation (like a linked list instead of an array) to do that. I don't know what is right. Coding an algorithm within the space of an interview has at least 3 constraints: time to code, elegance/readability, and efficiency of execution. What trade-offs are appropriate for interview code? How much do you follow the textbook definition of an algorithm? Is it better to eliminate recursion, unroll loops, and use arrays for efficiency? Or is it better to use recursion and special values like "infinity" or Integer.MAX_VALUE to reduce the number of lines of code needed to write the algorithm? Interface: Make a very self-contained, bullet-proof interface, or sloppy and fast? On the one extreme, the array to be sorted might be a public static variable. On the other extreme, it might need to be passed to each method, allowing methods to be called individually from different threads for different purposes. Is it appropriate to use a linked-list data structure for items that are traversed in one direction vs. using arrays and doubling the size when the array is full? Implementing a singly-linked list during the interview is often much faster to code and easier remember for recursive algorithms like MergeSort. Thread safety - just document that it's unsafe, or say so verbally? How much should the interviewee be looking for opportunities for parallel processing? Is bit shifting appropriate? x / 2 or x >> 1 Polymorphism, type safety, and generics? Comments? Variable and method names: qs(a, p, q, r) vs: quickSort(theArray, minIdx, partIdx, maxIdx) How much should you use existing APIs? Obviously you can't use a java.util.HashMap to implement a hash-table, but what about using a java.util.List to accumulate your sorted results? Are there any guiding principals that would answer these and other questions, or is the guiding principal to ask the interviewer? Or maybe this should be the basis of a discussion while writing the code? If an interviewer can't or won't answer one of these questions, are there any tips for coaxing the information out of them?

• Essbase 11.1.2 - AgtSvrConnections Essbase Configuration Setting

  - by Ann Donahue

  AgtSvrConnections is a documented Essbase configuration setting used in conjunction with the AgentThreads and ServerThreads settings. Basically, when a user logs into Essbase, the AgentThreads connects to the ESSBASE process then the AgtSvrConnections will connect the ESSBASE process to the ESSSVR application process which then the ServerThreads are used for end user activities. In Essbase 11.1.2, the default value of the AgtSvrConnections setting was changed to 5. In previous Essbase releases, the AgtSvrConnections setting default value is 1. It is recommended that tuning the AgtSvrConnections settings be done incrementally by 1 or 2 maximum and based on the number of concurrent Set Active/Clear Active calls. In the Essbase DBA Guide and Technical Reference, the maximum setting recommended is to not exceed what is set for AgentThreads, however, we have found that most customers do not need to exceed a setting of 10. In general, it is ok to set AgtSvrConnections close to the AgentThreads setting, however, there have been customers that needed an AgentThread setting greater than 10 and we have found that the AgtSvrConnections setting higher than 5-10 could have a negative impact on Essbase due to too many TCP ports used unnecessarily. As with all Essbase.cfg settings, it is best to set values to what is needed based on process load and not arbitrarily set to high values. In order to monitor and tune the AgtSvrConnections setting, monitor the application log for logins and Set Active/Clear Active messages. If there are a lot of logins and Set Active/Clear Active messages happening in a short period of time making it appear that the login is taking longer, incrementally increase the AgtSvrConnections setting by 1 or 2, which can then help with login speed. The login performance tolerance is different from one customer environment to another since there are other factors that can impact this performance i.e. network latency. What is happening in Essbase when a user logs in: ESSBASE issues a Set Active to the ESSSVR process. Each application has its own ESSSVR process. Set Active then calls MultipleAsyncLogout and waits on the pipe connection. MultipleAsyncLogout goes back to ESSBASE. ESSBASE then needs to send the logout back to the ESSSVR process. When the AgtSvrConnections setting needs to be increased from the default of 5, it is because Essbase cannot find a connection since the previous connections are used by ESSBASE-ESSSVR. In this example, we may want to increase AgtSvrConnections from 5 to 7 to improve the login performance. Again, it is best to set Essbase settings to what is needed based on process load and not arbitrarily set to high values. In general, stress or performance testing environments using automated tools may need higher than normal settings. This is because automated processes run at high speeds for logging in and logging out. Typically, in a real life production environment, the settings are much closer to default values.

• New Source Database Added for EBS 12 + 11gR2 Transportable Tablespaces

  - by John Abraham

  The Transportable Tablespaces (TTS) process was originally certified for the migration of E-Business Suite R12 databases going from a source database of 11gR1 or 11gR2 to a target of 11gR2. This requirement has now been expanded to include a source database of 10gR2 (10.2.0.5) - this will potentially save time for existing 10gR2 customers as they can remove on a crucial upgrade step prior to performing the platform migration. The migration process requires an updated Controlled patch delivered by the Oracle E-Business Suite Platform Engineering team, i.e. it requires a password obtainable from Oracle Support. We released the patch in this manner to gauge uptake, and help identify and monitor any customer issues due to the nature of this technology. This patch has been updated to now include supporting 10gR2 as a source database. Does it meet your requirements?Note that for migration across platforms of the same "endian" format, users are advised to use the Transportable Database (TDB) migration process instead for large databases. The "endian-ness" target platforms can be verified by querying the view V$DB_TRANSPORTABLE_PLATFORM using SQL*Plus (connected as sysdba) on the source platform:SQL>select platform_name from v$db_transportable_platform;If the intended target platform does not appear in the output, it means that it is of a different endian format from the source. Consequently. database migration will need to be performed via Transportable Tablespaces (for large databases) or export/import.The use of Transportable Tablespaces can greatly speed up the migration of the data portion of the database. However, it does not affect metadata, which must still be migrated using export/import. We recommend that users initially perform a test migration on their database, using export/import with the 'metrics=y' parameter. This will help identify the relative amounts of data and metadata, and provide a basis for assessing likely gains in timing. In general, the larger the amount of data (compared to metadata), the greater the reduction in downtime that can be expected from using TTS as a migration process. For smaller databases or for those that have relatively small data compared to metadata, TTS will not be as beneficial for cross endian migration and the use of export/import (datapump) for the whole database is recommended.

• Big Data – Buzz Words: What is NewSQL – Day 10 of 21

  - by Pinal Dave

  In yesterday’s blog post we learned the importance of the relational database. In this article we will take a quick look at the what is NewSQL. What is NewSQL? NewSQL stands for new scalable and high performance SQL Database vendors. The products sold by NewSQL vendors are horizontally scalable. NewSQL is not kind of databases but it is about vendors who supports emerging data products with relational database properties (like ACID, Transaction etc.) along with high performance. Products from NewSQL vendors usually follow in memory data for speedy access as well are available immediate scalability. NewSQL term was coined by 451 groups analyst Matthew Aslett in this particular blog post. On the definition of NewSQL, Aslett writes: “NewSQL” is our shorthand for the various new scalable/high performance SQL database vendors. We have previously referred to these products as ‘ScalableSQL‘ to differentiate them from the incumbent relational database products. Since this implies horizontal scalability, which is not necessarily a feature of all the products, we adopted the term ‘NewSQL’ in the new report. And to clarify, like NoSQL, NewSQL is not to be taken too literally: the new thing about the NewSQL vendors is the vendor, not the SQL. In other words - NewSQL incorporates the concepts and principles of Structured Query Language (SQL) and NoSQL languages. It combines reliability of SQL with the speed and performance of NoSQL. Categories of NewSQL There are three major categories of the NewSQL New Architecture – In this framework each node owns a subset of the data and queries are split into smaller query to sent to nodes to process the data. E.g. NuoDB, Clustrix, VoltDB MySQL Engines – Highly Optimized storage engine for SQL with the interface of MySQ Lare the example of such category. E.g. InnoDB, Akiban Transparent Sharding – This system automatically split database across multiple nodes. E.g. Scalearc  Summary In simple words – NewSQL is kind of database following relational database principals and provides scalability like NoSQL. Tomorrow In tomorrow’s blog post we will discuss about the Role of Cloud Computing in Big Data.

• Choose Custom New Tab Pages in Chrome

  - by Asian Angel

  For most people the default New Tab Page in Chrome works perfectly well for their purposes. But if you would prefer to choose what opens in a new tab for yourself then you will definitely want to have a look at the “Define your own new tab!” extension for Google Chrome. Before Unless you are using a Speed Dial (or similar) extension each time you click on the “New Tab Button” you get the same old page. It would certainly be a lot more satisfying if you could choose custom webpage(s) to open as new tabs. After Once you have the extension installed the best thing to do is click on the “New Tab Button”. That will open up the “Options Page” where you can enter one or two custom website URLs of your choosing. Once you have your custom URLs entered click on “Save”. As soon as you click on the “New Tab Button” your new custom webpage(s) will open. If you chose two webpages the first choice will open focused on the “right side” instead of the “left”. Clicking on the “Home Button” will also open the webpage(s) that you chose. The webpage(s) that you chose will also open as your starting “Home Pages” each time that you start your browser. Conclusion If you have wanted to choose your own custom “New Tab Page” then this is the extension that you have been waiting for.

• How can I solve this SAT edge case?

  - by ssb

  I have an SAT implementation that basically works, and the fact that it works is what's giving me a few headaches. Basically there are some situations where using the SAT doesn't quite give me my intended result. One of these involves movement across multiple collision objects. Or to put it another way, if I have several collision boxes lined up next to each other such as to create something like a wall or a floor, movement along that surface while constantly applying force into that surface sometimes causes hangups, i.e. the player stops moving. This illustration shows what I mean: The 2 boxes on the bottom represent a floor, and the box on top/in the middle represents what my player is doing. There are several squares lined up as world obstacles to create some kind of wall, and if I move to the left across this surface while holding the down key then the issue arises. It only happens at the exact dividing point between two blocks. It only happens when moving to the left. At any rate I think I know why it happens, but I don't know how to solve it. Basically when I update my player movement I consider which directions are pressed, naturally, so if down is pressed I will add the speed to the Y component, and so on. But due to the way my SAT is implemented, when the penetration into the shape is the same from both sides it just goes with the smallest axis that it finds first, and it checks collisions against objects in the order that they were created because it goes through a foreach loop on the list of collidable objects. So this all adds up to the effect of if I'm moving to the left over a series of boxes while holding down, it will resolve me back to the right out of the first box and then up out of the box to the right of it, and this continues as long as the penetration is the same. The odd part is that this doesn't happen every time, which I am going to attribute to some oddity regarding multiplying velocity by the game time and causing some minor discrepancies between the lengths. Ultimately what this boils down to is that it will keep resolving me to the right and up, but this is technically expected behavior. All the solutions I can think of only address the symptoms of this problem and not the actual cause, such as not using many blocks to create walls or shapes, which is an option I'd like to keep open. I could also change which axis my algorithm defaults to, but that would just cause problems when going up/down along the walls. What can I do to fix this?

• Evaluating Scrum - is it okay to have people with multiple roles in a Scrum team?

  - by Wayne M

  I'm evaluating some Agile-style methodologies for possible introduction to my team. With Scrum, is it allowable to have the same person perform multiple roles? We have a small team of four developers and a web designer; we don't really have a lead (I fulfill this role), QA testers or business analysts, and all of our development tasks come from the CIO. Automated testing is seen as a total waste of time, and everything focuses on speed and not quality. What will happen is the CIO will come up with a development task (whether a feature or a bug) and give it to a developer (not to the whole team, to an individual, often in private or out of the blue) who is then expected to get it completed. The CIO doesn't gather requirements beyond the initial idea (and this has bitten us before as we'll implement something only to find out that none of the end users can use the feature, because they weren't consulted or even informed about it before we developed it, and in a panic we'll be told to revert the change) but requires say in/approval of everything that we do. First things first, is a Scrum style something to consider to introduce some standards and practices? From reading, Scrum seems to rely on a bit more trust and communication and focuses more on project management than on development, which is something we are completely devoid of as we don't have any semblance of project management at present. Second, if it can work is it unreasonable for someone, let's say myself, to act as both ScrumMaster and a developer? Or for a developer to also be the Product Owner (although chances are this will be the CIO, who isn't a developer)? I realize the Scrum Master and the Product Owner should be different people but at the same time I don't think we have anyone who has the qualities of a Product Owner (chances are it would turn into a "I need all these stories, I don't care how but get it done" type of deal and/or any freeze would be unfrozen on a whim). It seems to me that I might need to pick and choose pieces of Scrum/XP/Lean to compensate for how things are done currently, as it's highly unlikely that the mentality can be changed; for instance Pair Programming would never fly (seen as a waste, you get half the tasks done if you need two people for everything), TDD would be a hard sell, but short cycles would be welcomed.

  The Real Architects of Los Angeles: OTN Architect Day in LA - Oct 25 No gossip. No drama. No hair pulling. Just a full day of technical sessions and peer interaction focused on using Oracle technologies in today's cloud and SOA architectures. The event is free, but seating is limited, so register now. Thursday October 25, 2012. 8:00 a.m. – 5:00 p.m. Sofitel Los Angeles, 8555 Beverly Boulevard, Los Angeles, CA 90048. Why IT is a profession in 'flux' | ZDNet I usuallly don't post two items from the same person in one day, but this post from ZDNet blogger Joe McKendrick deals with some critical issues affecting those in IT. As McKendrick puts it: "IT professionals are under considerable pressure to deliver more value to the business, versus being good at coding and testing and deploying and integrating." Cloud, automation drive new growth in SOA governance market | ZDNet "SOA governance tools and processes learned over the past decade are now underpinning cloud projects as they scale across enterprises," reports Joe McKendrick. But there remains a lack of understanding about SOA Governance. For a broader discussion of the importance of IT governance check out the lastest OTN Archbeat Podcast: By Any Other Name: Governance and Architecture How I Simplified the Installation of Oracle Database on Oracle Linux 6 Michele Casey's update of Ginny Henningsen's original article. This version shows how to simplify the installation of Oracle Database 11g on Oracle Linux 6 by installing the oracle-rdbms-server-11gR2-preinstall RPM package. Fault Handling Slides and Q&A | Ronald van Luttikhuizen Oracle ACE Director Ronald van Luttikhuizen shares the slides and a Q&A transcript from a presentation he and fellow ACE Director Guido Schmutz gave at the recent Oracle OpenWorld and JavaOne preview event organized by AMIS Technology. BPM ADF Task forms. Checking whether the current user is in a BPM Swimlane | Christopher Karl Chan "The tricky part here is that the ADF Task Details Form is in fact part of a separate J2EE application to the main workspace," says Oracle Fusion Middleware A-Team member Christopher Karl Chan. "So if you try to use Java or Expression Language to get the logged in user you will only find anonymous and none of the BPM Roles you will be expecting. So what to do?" Don't guess—read the post and find out. Thought for the Day "The speed of change makes you wonder what will become of architecture. " — Tadao Ando Source: BrainyQuote

• Why does my sprite glitch when moving? [closed]

  - by rphello101

  Using Slick 2D/Java, I'm using the mouse to rotate a sprite and WASD to move it (A and D are used to strafe). I finally got the directional keys and rotation to work in sync, but I'm having problems with sporadic movement. It seems that the move speed is not always set to the value I have it at. Sometimes the sprite with just shoot across the screen. Furthermore, it seems that at 0 degrees, when the left key is pressed, the sprite moves backwards, not to the left. There also seems to be quite a bit of glitching when two keys are pressed, like left and up. Anyone see anything obvious? Here is the rotational code: int mX = Mouse.getX(); int mY = HEIGHT - Mouse.getY(); int pX = sprite.x+sprite.image.getWidth()/2; int pY = sprite.y+sprite.image.getHeight()/2; double mAng; if(mX!=pX){ mAng = Math.toDegrees(Math.atan2(mY - pY, mX - pX)); if(mAng==0 && mX<=pX) mAng=180; } else{ if(mY>pY) mAng=90; else mAng=270; } sprite.angle = mAng; sprite.image.setRotation((float) mAng); Movement code: Input input = gc.getInput(); Vector2f direction = new Vector2f(); Vector2f velocity = new Vector2f(); Vector2f left; Vector2f right; direction.x = (float) Math.cos(Math.toRadians(sprite.angle)); direction.y = (float) Math.sin(Math.toRadians(sprite.angle)); if(direction.length()>0) direction = direction.normalise(); left = new Vector2f(-direction.y, direction.x); right = new Vector2f(direction.y, -direction.x); velocity.x = (float) (direction.x * sprite.moveSpeed); velocity.y = (float) (direction.y * sprite.moveSpeed); if(input.isKeyDown(sprite.up)){ sprite.x += velocity.x*delta; sprite.y += velocity.y*delta; }if (input.isKeyDown(sprite.down)){ sprite.x -= velocity.x*delta; sprite.y -= velocity.y*delta; }if (input.isKeyDown(sprite.left)){ sprite.x += left.x * sprite.moveSpeed * delta; sprite.y += left.y * sprite.moveSpeed * delta; }if (input.isKeyDown(sprite.right)){ sprite.x += right.x * sprite.moveSpeed * delta; sprite.y += right.y * sprite.moveSpeed * delta; }
