Upgraded to iOS 7 beta / Xcode 5 beta and receiving warning "CODE_SIGN_ENTITLEMENTS specified without a valid Developer Signing Identity for iOS"
The problem is not with the Code Signing Entitlements. The problem is most probably with the Code Signing Identity. In Xcode 4 the automatic profile selector was looking for a profile named: iPhone Developer. However, it seems in Xcode 5 the automatic profile selector is looking for a profile named: iOS Developer (as it can be seen in your screenshot) which most probably doesn't exist. In order to fix this problem try manually selecting an existing profile from the Code Signing Identity drop-down list.

Beta testing an iOS app with iOS 7 beta
General Notes Might I recommend you look into http://www.testflightapp.com? Among other things, it will ensure: You have his UUID without error He can download your app You can collect feedback, crash reports, and "checkpoint" information about his usage. You can enlist the help of others as well using this (and similar) services, making this whole problem a lot easier to manage now and in the future. How to enable iOS Beta version installs: Once you're sure you have his UUID, put it into your developer account's device list using the Apple Developer Portal, and he will be able to install iOS 7 Beta using iTunes. You may want to either add his apple ID to your developer account so he can download the beta, or otherwise arrange to get the .DMG to him. How to distribute your app:

OracleJDBC Driver : Does driver commits on close() by default even if conn.setAutoCommit is False?
When a Connection is closed, it needs to either rollback or commit the current transaction. IIRC, the JDBC specification allows an implementation to choose either as long as it is consistent in its behavior (always commit or always rollback on close). So yes, the behavior is allowed and so it is correct. If it is the best choice is debatable: you can argue that committing on close makes sure no information is lost, on the other hand you didn't explicitly commit, so maybe you didn't want the info to be persisted.

Error: The path to the driver executable must be set by the webdriver.chrome.driver system property
Using selenium-server-standalone-*.jar from here, you can pass webdriver.chrome.driver property when launching it like so: java -jar selenium-server-standalone-2.35.0.jar -Dwebdriver.chrome.driver="D:devchromedriver.exe" This eliminates the error; Java command line option -Dproperty=value sets a system property value as expected.

Easiest driver for a Linux Device Driver newbie
You should start by studying the basics of Loadable Kernel Modules. First few chapters of LKMPG by Salzman will be a good start And the easiest driver, IMHO, is a simpleton driver that uses memory as a device and reads/write to it. One such driver is beautifully explained in third chapter of LDD3e. You would also need to increase your knowledge of the Linux Kernel itself in order to advance towards relatively hard drivers. The better you understand Kernel's subsystems the easier it will be for you to develop device drivers around them.

why can't I run my games in python
You have to include pygame.init() in your code before you do anything with video. Hope that fixes the problem. I wouldn't learn Python by starting with pygame. Try watching Bucky's tutorials at TheNewBoston on Python. They will teach you about basic python syntax. Although he does a pretty good job at teaching the Python basics, I advice you to look through the python documentation and read about useful modules, features, etc. When you feel ready to do graphics, check his tutorials on game development (pygame). After that, just make something.

XA Datasource in Microsoft JDBC driver and jTDS JDBC Driver
Found the answer after digging in jTDS driver distribution. It has README.XA file saying it all. Copying the content below. XA support in jTDS ================== This version of jTDS includes a XADataSource class which allows the driver to be used with J2EE servers that only support XA JDBC connections. The class name is net.sourceforge.jtds.jdbcx.JtdsDataSource. By default the driver will emulate distributed transactions fooling the J2EE environment into believing that two phase commit is supported. This emulation has the serious drawback that when used in a true distributed environment, the driver may not be able to commit or rollback when requested by the transaction manager. In this situation data loss or corruption can occur. In general this emulation is safe to use when jTDS is t

A local repository to update games?
Version Control Systems work with revisions, yes, that counts for either SVN and git. In case of new program versions it naturally makes sense to put them into revisions, as they are usually only a snapshot of XYZ in a certain point in time. XYZ being whatever want it to be, binary programs, images, files, etc. But to make it really part of a revision you would also need to commit the newly fetched changes. That in the end makes a new revision of your (let's say) games tree. Those revisions then can be fetched from the client computers. That can happen either by scripts that automatically check the server every couple of minutes (cronjobs?) for changes or manually. The benefit of that workflow is quite obvious, in case your new versions are not what you want (e.g. later you notice they

Database schema for two-player games
I would definitely do one row per score (i.e. 2 rows per game). I would store the player, and points, and if I wanted the opponent player/points, I'd look that up separately. I would almost certainly have a separate table for each game, which would mention things like when it was played, etc No redundant data, everything is easy to gather etc.

Android Games specifically bitmaps
Depending on how dynamic your bitmaps render will be, you should go for either GLSurfaceView or SurfaceView, for something simple as just bitmaps i would recommend you to use SurfaceView as "renderer" where you can get the canvas from and of course you can draw on the whole screen if your surfaceview match the screen size. TouchListener should be completely separated handled on its own listener promoting encapsulation and reuse of code for future apps that you want to do. I've found this quiet helpful for the last games i've developed asingning a surface view as renderer and just creating Objects which takes the canvas as parameter and drawing them self into it, the only thing you have to take on count is the bitmap resource management, but if you are careful of releasing and creating the

It's "local" to the ClassLoader which defines the class. It's unconnected to any instances of the class - for example, the variable can still be used even if there are no instances of the class. But it won't automatically be shared between different JVMs or even different ClassLoaders within the same JVM.

Application marked as using Play Games
Quoting my answer from another question: http://stackoverflow.com/a/17633229/226508 Implementing the Google Play Game Services features is not sufficient, your users have to use the service for you to get the badges. Let me quote from this video from Google I/O 2013: Practical Android Games Development http://youtu.be/ZbQWf7C5ymU?t=23m39s "As you get more users you will get badges. [...] However, they are not just given out because you put them in the config, and we don't snoop your APK to see if you are making API calls from there. We verify how much the feature is being used and if you meet certain threshold we give you a badge. So you need to actually integrate it, it is not a token thing that you can put there to get more eyeballs in the store."

Developing Html5 and Mobile Games
HTML5 is still new, so there are a lot of emerging engines and development tools. Unfortunately, this means there are a lot of 'fly-by-the-night' engines that don't last long. The two companies with the most funding to work with are Game Closure and Turbulenz, so those are making more of a push for the 'professional' game developer audience. Funding doesn't always mean reliability however - they have more demand to reach for a higher exit for the company, and if they're not able to raise secondary rounds, they will be dead in the water. An alternative suggestion would be something like ImpactJS, which, while developed primarily by one person, has been reliably updated over the course of 2 and a half years.

How to secure Flash Games from Cheat Engine?
You can't. It's unavoidable. Abandon all hope. Your game is client-side and can be tampered with. The score is sent from the client which can be intercepted and changed before it is sent to the server. Anything you do to try encode the score will fail because your SWF can be decompiled and the algorithm reverse-engineered. Even if you put yourself through hell to obfuscate your SWF and the logic used to encode a decode a score, you will not prevail. All you can do is make it not worthwhile to cheat by maximising the difficulty of sending faux scores; make the criteria of a valid score strict and hard to determine e.g. a multiple of a given number minus x.

Can my app load only the games installed on users device?
In Android, you cannot set your app as "Game Type" so you cannot filter applications by this category. I think, a solution to this would be to find all games packages from Google Play and put that list in your app and frequently update it. It needs uninterrupted internet connection so that you could send found apps list to server and server will return back games from that list. So, you need to write server code for that.

How are Optimzed graphics games developed in Android
OpenGL ES is probably the most popular solution because it is pretty fast and supports 3D drawing. Not to mention iOS supports OpenGL ES too (AFAIK) which allows one to develop a cross-platform graphics layer. AndEngine is a popular platform for developing games on Android that sits on top of OpenGL ES, and the example apps show off some pretty cool graphics.

Why is Audio such an issue in HTML5 Games and how soon will it be corrected?
You have to understand that different browsers support different types of audio files as shown on this website http://html5doctor.com/html5-audio-the-state-of-play/ This is mainly due to the lack of regulations and standards surrounding HTML 5, users and developers may find it difficult to support all audio formats on all browsers. I've read somewhere that you can add in different audio formats and if one fails, it will play the other format but I can't find the link again. Sorry :( Good Luck

Server side validation for 'active' games
Not sure how many games used a shared client/server model but it's probably a fair share of action games these days. Basically the server and client share most of the codebase and both simulate the game simultaneously (it helps if your methods are all deterministic, but it doesn't matter for things like graphical effects such as sparks/explosions, which don't affect the core gameplay) The server sends updates to the client to tell it what's actually happening and the client corrects for errors. This is why in some action games when you have a network spike where you drop some packets, you can carry on running around shooting at people, and then suddenly the server re-establishes communications and puts you back where you were 5 seconds ago! The server controls all important interactions

Steam API getOwnedGames showing games not in library
One possibility is to filter 'games' that have "playtime_forever": 0. As an example, this would filter appids 9, 92, 211 from the below snippet. { "appid": 9, "playtime_forever": 0 }, { "appid": 92, "playtime_forever": 0 }, { "appid": 211, "playtime_forever": 0 }, { "appid": 440, "playtime_2weeks": 188, "playtime_forever": 107307 }, This is going to catch everything for you though, because people that have 'played' these games will have play time. So, for the above you would have filtered out the Source SDK, but for another user that has used it the SDK would appear.
