What is Transparent Data Encryption (TDE) ? Oracle Advanced Security Transparent Data Encryption (TDE) allows you to protect data at rest. TDE helps address privacy and PCI requirements by encrypting personally identifiable information (PII) such as Social Security numbers and credit card numbers. TDE is completely transparent to existing applications with no triggers, views or other application changes required. Data is transparently encrypted when written to disk and transparently decrypted after an application user has successfully authenticated and passed all authorization checks. Authorization checks include verifying the user has the necessary select and update privileges on the application table and checking Database Vault, Label Security and Virtual Private Database enforcement policies.

• Lockdown Your Database Security

  - by Troy Kitch

  A new article in Oracle Magazine outlines a comprehensive defense-in-depth approach for appropriate and effective database protection. There are multiple ways attackers can disrupt the confidentiality, integrity and availability of data and therefore, putting in place layers of defense is the best measure to protect your sensitive customer and corporate data. “In most organizations, two-thirds of sensitive and regulated data resides in databases,” points out Vipin Samar, vice president of database security technologies at Oracle. “Unless the databases are protected using a multilayered security architecture, that data is at risk to be read or changed by administrators of the operating system, databases, or network, or hackers who use stolen passwords to pose as administrators. Further, hackers can exploit legitimate access to the database by using SQL injection attacks from the Web. Organizations need to mitigate all types of risks and craft a security architecture that protects their assets from attacks coming from different sources.” Register and read more in the online magazine format.

• How to Create a Custom Ubuntu Live CD or USB the Easy Way

  - by Chris Hoffman

  There are several different ways to create custom Ubuntu live CDs. We’ve covered using the Reconstructor web app in the past, but some commenters recommended the Ubuntu Customization Kit instead. It’s an open-source utility found in Ubuntu’s software repositories. UCK offers more powerful features than Reconstructor does, but Reconstructor makes most tasks easier for novice users. Be sure to take a look at Reconstructor, too.

• How to Change Your Default Applications on Ubuntu: 4 Ways

  - by Chris Hoffman

  There are several ways to change your default applications on Ubuntu. Whether you’re changing the default application for a particular task, file type, or a system-level application like your default text editor, there’s a different place to go. Unlike on Windows, applications won’t take over existing file extensions during the installation process — they’ll just appear as an option after you install them.

• PowerShell for breakfast, lunch and dinner

  - by Enrique Lima

  Actually, for snacks too, and it is nearly everywhere I turn. If I do Microsoft Exchange work, I know I will run into it.  Active Directory, SQL Server, TFS, SharePoint, Azure and most recently Lync. All have provided a way to work with PowerShell and it has taken off (as it should). The question many will have is, How do I get started? A couple of ways are available. There are books, sites and blogs that will help you along the way. This will be the start of a series of posts that, my intention at least, will highlight and focus on the main features I have been using with the different products I interact. Here are some useful links to get started … The Master PowerShell book from Dr. Tobias Weltner PowerShell.com Script Center @ Technet

• frame lock networking

  - by kochol

  I'm developing an RTS game and I want to add multiplayer support to my game. I picked the easiest technique to implement for start frame locking technique. I used server client networking architecture (I think it's my first mistake I think using peer to peer is a better one for this) On game update every clients send their commands and maybe receive some command then render the frame and wait for all clients to send their update complete message then all of them can go for the next frame. I send commands and all logic is calculated on the clients based on commands but the clients can go out of sync easily. Every AI controlled units make different decisions on each clients What I have to do to sync my game? Do you suggest me a better network architecture or technique?

• How to make custom shaped holes in terrain

  - by Guy Ben-Moshe

  So I'm trying to create a game where you fit certain shaped objects into the hole that fits them (similar to the young children's game with different shaped blocks) in Unity 3D. I've encountered a problem, how do I make the holes in the terrain? Or what type of object should I use for making holes in? So far I've tried to make a 3d model in unity by using other cubes and planes, it just doesn't feel right. I guess I need to create a model in another software and import to unity, I don't know any other software I can use. Tips would help.

• Why is there still so much offer for Perl programmers?

  - by user491444

  A quick search on monster.com on different scripting languages resulted on Perl having much more job opportunities than Python and Ruby (in Europe, I didn't check for the rest of the world), and since I'm just a newbie programmer I was wondering why is this? I've read everywhere that Python and Ruby are much better languages, and much more organized. Having coded in python and php myself, Perl's code seems so alien to me. Anyways, sorry for my poor English, it's my second language, and this is not a critique on the Perl language, I was just wondering whether it's a good idea to learn it at this point or not.

  I need to extract very particular data from log files(of different types and formats). Since I am a recent college passout; my mind ran to using Lex and Yacc for the purpose.

Also ; I would like to know if I am being too afraid to write my own parser? 3. How can I use Lex and Yacc if my product is Windows based? Please tell me if you need any clarification or extra information.

• IIS7 Serving .mp4s, not playable on iOS devices.

  - by Danomite

  I've added the proper MIME type to the server, made sure it applies to not only the specific site but even the all of server's sites. The file is accessible and playable in my browser (Chrome) but when trying to pull it up on an iPhone , the debug mode warns me that the "movie could not be played" but on iPad it's "byte_range_error_message" I'm really at a loss here of why iOS devices won't load the video up. I know it's not the video files themselves because I had used the same file on a different server (on a shared hosting package). Any help is appreciated! -Dan

• Do you develop with security in mind?

  - by MattyD

  I was listening to a podcast on Security Now and they mentioned about how a lot of the of the security problems found in Flash were because when flash was first developed it wasdn't built with security in mind because it didn't need to thus flash has major security flaws in its design etc. I know best practices state that you should build secure first etc. Some people or companies don't always follow 'best practice'... My question is do you develop to be secure or do you build with all the desired functionality etc then alter the code to be secure (Whatever the project maybe) (I realise that this question could be a possible duplicate of Do you actively think about security when coding? but it is different in the fact of actually process of building the software/application and design of said software/application)

• Audiencing with Forms-Based Authentication (FBA)

  - by PeterBrunone

  This really is no different from when you create an audience with regular old NTLM (Windows Authentication).  The difference is that while the AD provider is set up by default in all environments, the extra membership provider (that you use for Forms Authentication) isn't included anywhere except in the web application where you install it.  To be able to find your FBA users in the audience creation tool, you'll need to add the extra membership provider(s) to the web.config for your SSP site in IIS.  At that point, the People Picker should start recognizing your Forms Auth users, and you can create your audience as needed.

• Architecture of interaction modes ("paint tools") for a 3D paint program

  - by Bernhard Kausler

  We are developing a Qt-based application to navigate through and paint on a volume treated as a 3D pixel graphic. The layout of the app consists of three orthogonal slice views on which the user may paint stuff like dots, circles etc. and also erase already painted pixels. Think of a 3D Gimp or MS Paint. How would you design the the architecture for the different interaction modes (i.e. paint tools)? My idea is: use the MVC pattern have a separate controler for every interaction mode install an event filter on all three slice views to collect all incoming user interaction events (mouse, keyboard) redirect the events to the currently active interaction controler I would appreciate critical comments on that idea.

• Game Maker Studio Gravity Problems

  - by Dusty

  I've started messing around with Game Maker Studio. The problem I'm having is trying to get a gravity code for orbiting. Here's how i did it in XNA foreach (GravItem Item in StarSystem.ActiveItems.OfType<GravItem>()) { if (this != Item) { Velocity += (10 * Vector2.Normalize(Item.Position - this.Position * (this.Mass * Item.Mass) / (Vector2.DistanceSquared(this.Position, Item.Position)) / (this.Mass)); } } Simple and works well, things or bit and everything is nice. but in Game maker i don't have the luxury of Vector2's or a For-each loop to loop threw all the objects that have a mass. I've tried a few different things but nothing seems to work distance = distance_to_object(obj_moon); //--Gravity hspeed += (0.5 * (distance) * (Mass * obj_moon.Mass) / (sqr(distance)) / Mass) vspeed += (0.5 * (distance) * (Mass * obj_moon.Mass) / (sqr(distance)) / Mass) thanks for the help

• iPhone image asset recommended resolution/dpi/format

  - by Matthew

  I'm learning iPhone development and a friend will be doing the graphics/animation. I'll be using cocos2d most likely (if that matters). My friend wants to get started on the graphics, and I don't know what image resolution or dpi or formats are recommended. This probably depends on if something is a background vs. a small character. Also, I know I read something about using @2x in image file names to support high res iphone screens. Does cocos2d prefer a different way? Or is this not something to worry about at this point? What should I know before they start working on the graphics?

• Single database, multiple system dependency

  - by davenewza

  Consider an environment where we have a single, core database, with many separate systems using this one database. This leads to all of these systems have a common dependency, which ultimately introduces coupling between them. This means that we cannot always evolve systems independently of each other. Structural changes to the database (even if only intended for one, particular system), requires a full sweep test of ALL systems, and may require that other systems be 'patched' and subsequently released. This is especially tricky when you want to have separate teams working on different projects. What is a good 'pattern' to help in avoiding such coupling? I would imagine that a database should be exclusively depended on by one system. If other systems require data for whatever reason, they should request such from an API service of some kind. A drawback of this approach which comes to mind is performance: routing data between high-throughput systems through service calls is much slower than through a database connection.

• Best practices for logging user actions in production

  - by anthonypliu

  I was planning on logging a lot of different stuff in my production environment, things like when a user: Logs In, Logs Off Change Profile Edit Account settings Change password ... etc Is this a good practice to do on a production enviornment? Also what is a good way to log all this. I am currently using the following code block to log to: public void LogMessageToFile(string msg) { System.IO.StreamWriter sw = System.IO.File.AppendText( GetTempPath() + @"MyLogFile.txt"); try { string logLine = System.String.Format( "{0:G}: {1}.", System.DateTime.Now, msg); sw.WriteLine(logLine); } finally { sw.Close(); } } Will this be ok for production? My application is very new so im not expecting millions of users right away or anything, looking for the best practices to keeping track of actions on a website or if its even best practice to.

• Service and/or tool to monitor performance?

  - by chris

  I am seeing wildly different performance from a clients web site, and would like to set up some sort of monitoring. What I'm looking for is a service that will issue requests to a couple of URLs, and report on the time it took to process the page - TTFB and time to download the entire page - that means I need something that will process javascript & css. Are there services like this? I've seen a few that monitor uptime, but they don't seem to report on the overall page performance.

• Advantages And Disadvantages Of Resource Serialization

  - by CPP_Person

  A good example is let's say I'm making a pong game. I have a PNG image for the ball and another PNG image for the paddles. Now which would be better, loading the PNG images with a PNG loader, or loading them in a separate program, serializing it, and de-serializing it in the game itself for use? The reason why this may be good to know is because it seems like game companies (or anyone in the long run) build all of their resources into some sort of file. For example, in the game Fallout: New Vegas the DLCs are loaded as a .ESM file, which includes everything it needs, all the game does is find it, serialize it, and it has the resources. Games like Penumbra: Black Plague take a different approch and add a folder which contains all the textures, sounds, scrips, ect that it needs, but not serialized (it does this with the game itself, and the DLC). Which is the better approch and why?

• How to make a battle system in a mobile indie game more fun and engaging

  - by Matt Beckman

  I'm developing an indie game for mobile platforms, and part of the game involves a PvP battle system (where the target player is passive). My vision is simple: the active player can select a weapon/item, then attack/use, and display the calculated outcome. I have a concept for battle modifiers that affect stats to make it more interesting, but I'm not convinced the vision is complete. I've received some inspiration from the game engine that powers Modern War/Kingdom Age/Crime City, but I want more control to make it more fun. In those games, you don't have the option to select weapons or use items, and the "battling" screen is simply 3D eye candy. Since this will be an indie game, I won't be spending $$$ on a team of professional 3D artists/animators, so my edge needs to be different. How would you make a battle system like this more fun and engaging?

• Looking Back at PASS Summit 2013 - Location

  - by RickHeiges

  Now that it has been a few weeks since the Summit, I wanted to look back at the location "experiment". Convention Center - It seemed to work well for the conference. There were quite a few areas in the area where you could sit down and get some work down or have a discussion. For the larger welcome reception the first night, I really liked the different areas. If you wanted to enjoy the Quiz Bowl, the ballroom area was set up nicely with big screens so that everyone could see and hear. The area right...(read more)
