• OWB 11gR2 &ndash; Parallel DML and Query

  - by David Allan

  A quick post illustrating conventional (non direct path) parallel inserts and query using OWB following on from some recent posts from Jean-Pierre and Randolf on this topic. The mapping configuration properties is where you can define these hints in OWB, taking JP’s simplistic illustration, the parallel query hints in OWB are defined on the ‘Extraction hint’ property for the source, and the parallel DML hints are defined on the ‘Loading hint’ property on the target table operator. If we then generate the code you can see the intermediate code generated below… Finally…remember the parallel enabled session for this all to fly… Anyway, hope this helps join a few dots….

• Lost Traffic from Google Because of Meta-tag Adding

  - by Marian

  I have a site aroundnails.com. It has English version on subdomain en.aroundnails.com. Reading about language related meta-tags for Google, I have placed such a meta tag on the main page of main site: <link rel="alternate" hreflang="en" href="http://en.aroundnails.com/" /> By this way I have tried to say Google, that my site on en.aroundnails.com is the english version of main site, not a duplicate. After a fortnight I have lost a huge part of traffic from Google, more than a half. At the beginning of September I have moved this meta-tag, but traffic remained at the same level. Hope somebody can help me to solve this issue.

• Problem with MVC3 application

  - by Pravin Patil

  I am working on MVC3 application. I use entity framework, NInject, Fluent Validation and some more Nuget packages. I am using Tortoise SVN for versioning. Recently I changed the structure of my SVN repository, so my working copy of MVC3 app was moved to some different folder in the repository. Now when I checked out the copy from SVN, all the references that I had added through Nuget were lost(EF, NInject and rest nuget packages were showing yellow missing icon in references). This had happened to me prior to this also, when I tried to check out the app from svn to some other folder. I had to manually add all the references again through Nuget again. Am I doing anything wrong? Please guide. I hope I could explain my problem properly.

• Referring to hardware/software in first-person? [closed]

  - by JYelton

  At my company, there is a habit for the engineers to refer to their respective hardware/firmware/software in the first-person as if the device they are responsible for is a manifestation of themselves. I'll give you an example: Hardware Engineer: "I don't receive the first byte, so I stay off." Software Engineer: "I'm sending you the first byte after the ack flag, so I thought you were getting it." Hardware Engineer: "No, you're not turning me on." It was this very example I overheard today that nearly had me giggling in fits. "You're not turning me on." Well, I should hope not! So, is it common practice for engineers to do this, or simply unprofessional? Any suggestions for changing this apparently bad habit?

• 2D game collision response: SAT & minimum displacement along a given axis?

  - by Archagon

  I'm trying to implement a collision system in a 2D game I'm making. The separating axis theorem (as described by metanet's collision tutorial) seems like an efficient and robust way of handling collision detection, but I don't quite like the collision response method they use. By blindly displacing along the axis of least overlap, the algorithm simply ignores the previous position of the moving object, which means that it doesn't collide with the stationary object so much as it enters it and then bounces out. Here's an example of a situation where this would matter: According to the SAT method described above, the rectangle would simply pop out of the triangle perpendicular to its hypotenuse: However, realistically, the rectangle should stop at the lower right corner of the triangle, as that would be the point of first collision if it were moving continuously along its displacement vector: Now, this might not actually matter during gameplay, but I'd love to know if there's a way of efficiently and generally attaining accurate displacements in this manner. I've been racking my brains over it for the past few days, and I don't want to give up yet! (Cross-posted from StackOverflow, hope that's not against the rules!)

• Speaking at AMD Fusion conference

  - by Daniel Moth

  Next Wednesday at 2pm I will be presenting a session at the AMD Fusion developer summit in Bellevue, Washington State. For more on this conference please visit the official website. If you filter the catalog by 'Speaker Last Name' to "Moth", you'll find my talk. For your convenience, below is the title and abstract Blazing-fast code using GPUs and more, with Microsoft Visual C++ To get full performance out of mainstream hardware, high-performance code needs to harness, not only multi-core CPUs, but also GPUs (whether discrete cards or integrated in the processor) and other compute accelerators to achieve orders-of-magnitude speed-up for data parallel algorithms. How can you as a C++ developer fully utilize all that heterogeneous hardware from your Visual Studio environment? How can your code benefit from this tremendous performance boost without sacrificing your developer productivity or the portability of your solution? The answers will be presented in this session that introduces a new technology from Microsoft. Hope to see many of you there! Comments about this post welcome at the original blog.

• Can't get my Blue Snowflake Mic to work

• structure problem in Relational DBMS creation

  - by Kane

  For learning and understanding purpose, I currently want to try to make a small relational DBMS with simple features like (for now) only sequential reading/writing and CREATE TABLE, INSERT, SELECT, UPDATE and DELETE management. I am currently on the "think" part of the project and I am stuck on the way to store the read data in memory. First I was thinking of putting them properly on a structure, but the problem is that tables are all different, know the type of each column is not an issue, but I am not sure C provide a way to make fully dynamic structure. My second and current idea is to make a simple char array of the required length and just get the data by order with cast. But I am not sure if it is the good way to do that part, so I wanted to ask for your opinion and advices about that. Thanks in advance for your help. nb: I hope my question is enough clear and understandable, I still lack of pratice in english

• History of open source software

  - by Victor Sorokin

  I've been always interested, out of the pure self-amusement, in the history of open software used today: who were the people which started it and what were the reasons to start what were design decisions at the start how software evolved over the time Specifically, I'm interested in following software: GCC X Linux kernel Java Of course, there is plenty of information in Internet to google for, but I thought it would be nice to have list of interesting resources at this site. I hope some of visitors of this site have similar interest and can share a link or two they found particularly amusing/interesting. To make this entry more question-like, here's straight question: what are the most interesting/amusing links about history of open source software?

• How was collision detection handled in The Legend of Zelda: A Link to the Past?

  - by Restart

  I would like to know how the collision detection was done in The Legend of Zelda: A Link To The Past. The game is 16x16 tile based, so how did they do the tiles where only a quarter or half of the tile is occupied? Did they use a smaller grid for collision detection like 8x8 tiles, so four of them make one 16x16 tile of the texture grid? But then, they also have true half tiles which are diagonally cut and the corners of the tiles seem to be round or something. If Link walks into tiles corner he can keep on walking and automatically moves around it's corner. How is that done? I hope someone can help me out here.

• GParted wont resize extended partitions

  - by Magnum Frost

  I have dual booted windows 7 and Ubuntu 12.04 LTS and have decided that I need more space on my Ubuntu partition. I used gparted on a Live CD to shrink my Windows 7 partition (/dev/sda3) but when i try to resize the extended partition (/dev/sda4), which houses my linux partition (/dev/sda6), the right click options are greyed out and there is a key next to the extended partition. I have resized the partitions within the extended partition before to provide room, but now I can go no further with that, and need to grow the extended partition. The free space lies to the left of the extended partition and there is a small amount of free space directly to the right as well. Also, within the extended partition is /dev/sda5 (ntfs) , which I have no idea what is on it, but most of the space (3.42GB) is used, /dev/sda6 (ext4, mount point: /), my partition containing Linux, and /dev/sda7 (linux-swap). I hope you guys can help me with this because I really don't want to screw something up while trying to resize the extended partition.

• What php programmer should know?

  - by emchinee

  I've dig the database here and didn't found any answer for my question. What is a standard for a php programmer to know? I mean, literally, what group of language functions, mechanisms, variables should person know to consider oneself a (good) php programmer? (I know 'being good' is beyond language syntax, still I'm considering syntax of plain php only) To give an example what I mean: functions to control http sessions, cookies functions to control connection with databases functions to control file handling functions to control xml etc.. I omit phrases like 'security' or 'patterns' or 'framework' intentionally as it applies to every programming language. Hope I made myself clear, any input appreciated :) Note: Michael J.V. is right claiming that databases are independent from language, so to put my question more precisely and emphasise differences: Practises or security, are some ideas to implement (there is no 'Pattern' object with 'Decorator()' method, is there?) while using databases means knowing a mysqli and a set of its methods.

• X technology is dead

  - by Daniel Moth

  Every so often, technology pundits (i.e. people not involved in the game, but who like commenting about it) throw out big controversial statements (typically to increase their readership), with a common one being that "Technology/platform X is dead". My former colleague (who I guess is now my distant colleague) uses the same trick with his blog post: "iPhone 4 is dead". But, his motivation is to set the record straight (and I believe him) by sharing his opinion on recent commentary around Silverlight, WPF etc. I enjoyed his post and the comments, so I hope you do too :-) Comments about this post welcome at the original blog.

• use ubuntu notebook as second monitor for fedora desktop

  - by YumTum

  I was wondering if there is a possibility to use my netbook with ubuntu 12.04 as a second monitor for my fedora desktop, because its keyboard is broken but everything else is running just fine. I already read about x2x, but I hope there is a more direct way to do this (I mean not over the WLAN but e.g. via LAN etc... ). Would it be possible to directly use the monitor without even running the laptop? For example through an VGA adapter? Thanks for your replies!

• Slower Rate of Convergence for U.S. GAAP and IFRS

  - by Theresa Hickman

  The original date of June 30, 2011 where FASB and IASB would align/converge major areas of accounting has been extended to the end of 2011. They will still meet the June 2011 date for many "urgently required" projects but some projects will not come until the second half of 2011. The reason for this is to allow more time for due diligence, review and consensus. Will this delay the U.S. adoption to IFRS? According to Ms. Schapiro, no, it will not; she is confident that the decision to adopt IFRS in the U.S. will be decided by 2011. I personally hope so because I fear that if the decision is delayed further, it might seep into the 2012 presidential election which could delay the adoption further. For more information, see reuters.com.

• Learning to optimize with Assembly

  - by niktehpui

  I am a second year student of Computer Games Technology. I recently finished my first prototype of my "kind" of own pathfinder (that doesn't use A* instead a geometrical approach/pattern recognition, the pathfinder just needs the knowledge about the terrain that is in his view to make decisions, because I wanted an AI that could actually explore, if the terrain is already known, then it will walk the shortest way easily, because the pathfinder has a memory of nodes). Anyway my question is more general: How do I start optimizing algorithms/loops/for_each/etc. using Assembly, although general tips are welcome. I am specifically looking for good books, because it is really hard to find good books on this topic. There are some small articles out there like this one, but still isn't enough knowledge to optimize an algorithm/game... I hope there is a modern good book out there, that I just couldn't find...

• bash script move file to folders based in name

  - by user289111

  I hope you can help me... I made a perl and bash script to make a backup of my firewalls and tranfers via tftp #!/bin/sh perl /deploy/scripts/backups/10.160.23.1.pl > /dev/null 2>&1 perl /deploy/scripts/backups/10.160.23.2.pl > /dev/null 2>&1 so this tranfers the file to my tftp directory /tftpboot/ ls -l /tftpboot/ total 532 -rw-rw-rw- 1 tftp tftp 209977 jun 6 14:01 10.160.23.1_20140606.cfg -rw-rw-rw- 1 tftp tftp 329548 jun 6 14:02 10.160.23.2_20140606.cfg my questions is how to improve my script to moving this files dynamically to another folder based on the name (in this case on the ip address) for example: 10.160.23.1_20140606.cfg move to /deploy/backups/10.160.23.1/ is that the answer to this surely was on Google, but wanted to know if there was a particular solution to this request and also learn how to do :) Thanks!
