• Force gdm login screen to the primary monitor

  - by Kirill

  I have two monitors attached to my video card. Primary monitor has a resolution equal to 1280x1024 and the second has 1920x1200. My gdm login screen always appears on the second monitor even if it is switched off. My question is how to force gdm to show the login screen always on the primary monitor with resolution 1280x1024? I use Nvidia GT9500 videcard in Twinview mode. I can't use Xinerama because vpdau doesn't work correclty in this mode. What I have found is that mouse pointer always appears in the center of union of the screens and center is always on the monitor with higher resolution. Login screen always shows where mouse cursor is. Now my primary monitor has a resolution equal to 1920x1080. The problem still persists, mouse cursor always appears in the right-bottom corner of the second monitor.

• how to process document state transition?

  - by brick

  Imagine there is an application (ASP.NET MVC) that processes some documents. The document must be revised several times by different group of users. state/role rules: simple user can only publish document; (priority: low) userGroup1 can switch it to next state or reject it; (priority: higher) userGroup2 can confirm previous state and switch it to next gradual state or reject it; (priority: highest) How to implement such a workflow in ASP.NET MVC? How to impelement UI, views so that group with lower priority can both visually/technically perform only allowed transitions? Can I somehow extend that system: link? Do I need extras like service bus, event sourcing for that?

• Do Google's feed statistics include former users?

  - by jjackson

  I'm currently not using any sort of fancy stat tracking software such as feedburner, but I occasionally look at Google's stats in their Webmaster Tools just to get a rough idea of whether the number of subscribers is going up or down. This only gives the number of users subscribed through Google products, as they explain in their help documents: Subscriber stats display the number of Google users who have subscribed to your feeds using any Google product (such as Reader, iGoogle, or Orkut). Because users can subscribe to feeds using many different aggregators or RSS readers, the actual number of subscribers to your site may be higher. I used to use Google Reader very regularly but haven't opened it in a while now. The way I understand it, this will mean that even though I haven't touched any of those feeds in a long time I'm still technically subscribed to them and will therefore be included in Google's statistic. Is this correct? Also since Google runs Feedburner, does this have any effect on their stats as well?

• Multiplayer mobile games and coping with high latency

  - by liortal

  I'm currently researching regarding a design for an online (realtime) mobile multiplayer game. As such, i'm taking into consideration that latencies (lag) is going to be high (perhaps higher than PC/consoles). I'd like to know if there are ways to overcome this or minimize the issues of high latency? The model i'll be using is peer-to-peer (using Photon cloud to broadcast messages to all other players). How do i deal with a scenario where a message about a local object's state at time t will only get to other players at *t + HUGE_LAG* ?

• Random thoughts on Monday

  - by user10760339

  I know that it has been a long time since my last post, just though that I would update you my latest thoughts of Governance. I just recently completed an executive round table series on EA and Cloud in Singapore, Indonesia and Malaysia. The response was phenomenal. The key point of the session was that Enterprise is the key enabler of innovation - All companies want to drive to be market leaders, EA can lay the foundation for the path to deliver that at innovation. When it comes to innovation, I see two distinct types: (a) Passive innovation is where a company creates innovation thought increments improvement over time. A great example is when airlines went from paper tickets to electronic ticket. Next logical progression is to do the same with boarding passes. There are a lot of examples to choose from, thought the thing to keep in mind, is that passive innovation will only keep you in the lead, it won’t allow you to create new markets or jump from #3 to #1 in one go. For that we need another type of innovation. (b) Disruptive innovation is where you create market where none existed before. Thought very difficult to do and requires significant investment in research, product and software development and not least of all, visionary thinking and timing, if done correctly, can turn the world on it’s ear. A great example is Apple iTunes. Some might say that this is incremental innovation, but only in one aspect, the downloading of music. Other then that, it’s all disruptive innovation. Being able to buy a single song rather then the album fundamentally changed the way we get out music. Behind all of these types of innovation is Enterprise Architecture. EA creates the infrastructure foundation, then delivery systems and the end-user experience to deliver this innovation. At Oracle, we are driving that EA innovation with our private cloud offerings from “bolt-to-glass” as I like to say. For more on what Oracle has to offer in EA and cloud, have a look at Cloud Computing | Oracle and Enterprise Architecture - OracleI am working on new material that I will be posting in a couple of weeks, so check back regularly for new updates or feel free to subscript for updates.

• How to Recover From a Virus Infection: 3 Things You Need to Do

  - by Chris Hoffman

  If your computer becomes infected with a virus or another piece of malware, removing the malware from your computer is only the first step. There’s more you need to do to ensure you’re secure. Note that not every antivirus alert is an actual infection. If your antivirus program catches a virus before it ever gets a chance to run on your computer, you’re safe. If it catches the malware later, you have a bigger problem. Change Your Passwords You’ve probably used your computer to log into your email, online banking websites, and other important accounts. Assuming you had malware on your computer, the malware could have logged your passwords and uploaded them to a malicious third party. With just your email account, the third party could reset your passwords on other websites and gain access to almost any of your online accounts. To prevent this, you’ll want to change the passwords for your important accounts — email, online banking, and whatever other important accounts you’ve logged into from the infected computer. You should probably use another computer that you know is clean to change the passwords, just to be safe. When changing your passwords, consider using a password manager to keep track of strong, unique passwords and two-factor authentication to prevent people from logging into your important accounts even if they know your password. This will help protect you in the future. Ensure the Malware Is Actually Removed Once malware gets access to your computer and starts running, it has the ability to do many more nasty things to your computer. For example, some malware may install rootkit software and attempt to hide itself from the system. Many types of Trojans also “open the floodgates” after they’re running, downloading many different types of malware from malicious web servers to the local system. In other words, if your computer was infected, you’ll want to take extra precautions. You shouldn’t assume it’s clean just because your antivirus removed what it found. It’s probably a good idea to scan your computer with multiple antivirus products to ensure maximum detection. You may also want to run a bootable antivirus program, which runs outside of Windows. Such bootable antivirus programs will be able to detect rootkits that hide themselves from Windows and even the software running within Windows. avast! offers the ability to quickly create a bootable CD or USB drive for scanning, as do many other antivirus programs. You may also want to reinstall Windows (or use the Refresh feature on Windows 8) to get your computer back to a clean state. This is more time-consuming, especially if you don’t have good backups and can’t get back up and running quickly, but this is the only way you can have 100% confidence that your Windows system isn’t infected. It’s all a matter of how paranoid you want to be. Figure Out How the Malware Arrived If your computer became infected, the malware must have arrived somehow. You’ll want to examine your computer’s security and your habits to prevent more malware from slipping through in the same way. Windows is complex. For example, there are over 50 different types of potentially dangerous file extensions that can contain malware to keep track of. We’ve tried to cover many of the most important security practices you should be following, but here are some of the more important questions to ask: Are you using an antivirus? – If you don’t have an antivirus installed, you should. If you have Microsoft Security Essentials (known as Windows Defender on Windows 8), you may want to switch to a different antivirus like the free version of avast!. Microsoft’s antivirus product has been doing very poorly in tests. Do you have Java installed? – Java is a huge source of security problems. The majority of computers on the Internet have an out-of-date, vulnerable version of Java installed, which would allow malicious websites to install malware on your computer. If you have Java installed, uninstall it. If you actually need Java for something (like Minecraft), at least disable the Java browser plugin. If you’re not sure whether you need Java, you probably don’t. Are any browser plugins out-of-date? – Visit Mozilla’s Plugin Check website (yes, it also works in other browsers, not just Firefox) and see if you have any critically vulnerable plugins installed. If you do, ensure you update them — or uninstall them. You probably don’t need older plugins like QuickTime or RealPlayer installed on your computer, although Flash is still widely used. Are your web browser and operating system set to automatically update? – You should be installing updates for Windows via Windows Update when they appear. Modern web browsers are set to automatically update, so they should be fine — unless you went out of your way to disable automatic updates. Using out-of-date web browsers and Windows versions is dangerous. Are you being careful about what you run? – Watch out when downloading software to ensure you don’t accidentally click sketchy advertisements and download harmful software. Avoid pirated software that may be full of malware. Don’t run programs from email attachments. Be careful about what you run and where you get it from in general. If you can’t figure out how the malware arrived because everything looks okay, there’s not much more you can do. Just try to follow proper security practices. You may also want to keep an extra-close eye on your credit card statement for a while if you did any online-shopping recently. As so much malware is now related to organized crime, credit card numbers are a popular target.

• Adjusting the Score on Oracle Text search results

  - by Kyle Hatlestad

  When you sort the results of a search by Score using OracleTextSearch as the search engine in WebCenter Content, the results coming back are based on the relevancy on the document.  In theory, the more relevant the search term is to the document, the higher ranked Score it should receive.  But in practice, the relevancy score can seem somewhat of a mystery.  It's not entirely clear how it ranks the importance of some documents over others based on the search term.  And often times, once a word appears a certain number of times within a document, the Score simply maxes out at 100 and the top results can be difficult to discern from one another.  Take for example the search for 'vacation' on this set of documents:  [Read More]

• What are the advantages and disadvantages of having a subdomain for each user account?

  - by Sathish Manohar

  I notice two types of design used in web applications, some with a particular subdomain for users contents, and some with same URL structure for all the accounts. Ex: unique.domain.com and another_unique.domain.com for subdomains for sites like blogspot, wordpress, basecamp etc. while in the other approach domain.com/action1 and domain.com/action2 the content is shown according to the user logged in, but the URL is same for every user. What are main differences between both of these kind of design?

• Artificial Intelligence implemented in x86 Assembly? [closed]

  - by Bigyellow Bastion

  Okay, so I decided that for my upcoming operating system, I do basically everything in x86 Assembly, using only 16-bit mode. I will need to write the software to host on it once I have something up and going, and I'll definitely post the source and VM-executable file. But as for now I'm stuck with the idea of implementing the AI code for some of the games I'm making to host on it. AI in Assembly is tedious, and sometimes almost impossible seeming, especially complex AI(I'm talking SNES Super Mario World 2: Yoshi's Island AI here, by the way, not pong AI). I was thinking that it'd be such a hassle that I'd have to bring a higher-level language to work some of this out here, like maybe C++ or C#, but I'd have to go through more work linking it into a fine binary that my OS will host, and that adds unnecessary work to the table I wanted to avoid(I don't want a complex system, I want everything as bare-bones as possible, avoiding libraries, APIs, and linkable formats for now, to make everything more directly accessible to the kernel's API).

• Analyze Drupal and Wordpress sites CPU load in shared server

  - by Tedi

  Our hosting company is complaining that both our Drupal and Wordpress websites running in a shared server are consuming too many CPU resources. The traffic for each site is not more than 100 users per day and, at a first glance, we don't have very many plugins/add-ons. Is there any tool or resource to analyse what is causing that high CPU load? Thanks Update: We decided to suspend our accounts while the problem was being debugged but still our hosting (Site5) said that they saw unacceptable activity on our sites so we had to move to a dedicated server... asked them several times to provide us with more information and they always came back saying that we had to purchase a higher account. Finally decided to move to another hosting service.

• HTG Explains: Why Does Rebooting a Computer Fix So Many Problems?

  - by Chris Hoffman

  Ask a geek how to fix a problem you’ve having with your Windows computer and they’ll likely ask “Have you tried rebooting it?” This seems like a flippant response, but rebooting a computer can actually solve many problems. So what’s going on here? Why does resetting a device or restarting a program fix so many problems? And why don’t geeks try to identify and fix problems rather than use the blunt hammer of “reset it”? This Isn’t Just About Windows Bear in mind that this soltion isn’t just limited to Windows computers, but applies to all types of computing devices. You’ll find the advice “try resetting it” applied to wireless routers, iPads, Android phones, and more. This same advice even applies to software — is Firefox acting slow and consuming a lot of memory? Try closing it and reopening it! Some Problems Require a Restart To illustrate why rebooting can fix so many problems, let’s take a look at the ultimate software problem a Windows computer can face: Windows halts, showing a blue screen of death. The blue screen was caused by a low-level error, likely a problem with a hardware driver or a hardware malfunction. Windows reaches a state where it doesn’t know how to recover, so it halts, shows a blue-screen of death, gathers information about the problem, and automatically restarts the computer for you . This restart fixes the blue screen of death. Windows has gotten better at dealing with errors — for example, if your graphics driver crashes, Windows XP would have frozen. In Windows Vista and newer versions of Windows, the Windows desktop will lose its fancy graphical effects for a few moments before regaining them. Behind the scenes, Windows is restarting the malfunctioning graphics driver. But why doesn’t Windows simply fix the problem rather than restarting the driver or the computer itself?  Well, because it can’t — the code has encountered a problem and stopped working completely, so there’s no way for it to continue. By restarting, the code can start from square one and hopefully it won’t encounter the same problem again. Examples of Restarting Fixing Problems While certain problems require a complete restart because the operating system or a hardware driver has stopped working, not every problem does. Some problems may be fixable without a restart, though a restart may be the easiest option. Windows is Slow: Let’s say Windows is running very slowly. It’s possible that a misbehaving program is using 99% CPU and draining the computer’s resources. A geek could head to the task manager and look around, hoping to locate the misbehaving process an end it. If an average user encountered this same problem, they could simply reboot their computer to fix it rather than dig through their running processes. Firefox or Another Program is Using Too Much Memory: In the past, Firefox has been the poster child for memory leaks on average PCs. Over time, Firefox would often consume more and more memory, getting larger and larger and slowing down. Closing Firefox will cause it to relinquish all of its memory. When it starts again, it will start from a clean state without any leaked memory. This doesn’t just apply to Firefox, but applies to any software with memory leaks. Internet or Wi-Fi Network Problems: If you have a problem with your Wi-Fi or Internet connection, the software on your router or modem may have encountered a problem. Resetting the router — just by unplugging it from its power socket and then plugging it back in — is a common solution for connection problems. In all cases, a restart wipes away the current state of the software . Any code that’s stuck in a misbehaving state will be swept away, too. When you restart, the computer or device will bring the system up from scratch, restarting all the software from square one so it will work just as well as it was working before. “Soft Resets” vs. “Hard Resets” In the mobile device world, there are two types of “resets” you can perform. A “soft reset” is simply restarting a device normally — turning it off and then on again. A “hard reset” is resetting its software state back to its factory default state. When you think about it, both types of resets fix problems for a similar reason. For example, let’s say your Windows computer refuses to boot or becomes completely infected with malware. Simply restarting the computer won’t fix the problem, as the problem is with the files on the computer’s hard drive — it has corrupted files or malware that loads at startup on its hard drive. However, reinstalling Windows (performing a “Refresh or Reset your PC” operation in Windows 8 terms) will wipe away everything on the computer’s hard drive, restoring it to its formerly clean state. This is simpler than looking through the computer’s hard drive, trying to identify the exact reason for the problems or trying to ensure you’ve obliterated every last trace of malware. It’s much faster to simply start over from a known-good, clean state instead of trying to locate every possible problem and fix it. Ultimately, the answer is that “resetting a computer wipes away the current state of the software, including any problems that have developed, and allows it to start over from square one.” It’s easier and faster to start from a clean state than identify and fix any problems that may be occurring — in fact, in some cases, it may be impossible to fix problems without beginning from that clean state.

• AdSense CPM and content topics

  - by Silver Moon

  I run a few blogs on topics like programming, linux tips and network security. I noticed the following: Till last year had only 1 blog that had posts on PHP, linux tips, network security etc. The AdSense RPM was around 1.00. Then I split the content into 3 separate blogs, one focused on web development/PHP/MySQL. second one focused on Linux/Windows how-tos and tips and third one focused on network security and related network topics. The Adsense RPM rose significantly for 2 blogs, and was 1.38 (PHP blog), 0.87 (tech tips blog) and 1.90 (network security blog). In the month of april 2013 the site on network security had the highest traffic and the Adsense income of that site was twice that of all three sites combined previously. My question is simple, does focusing on one topic lead to higher CPC/CPM?

• Recommended method towards making custom maps for a 2d game?
