• "Time Control" in a 2d Platformer

  - by Woody Zantzinger

  I am making a 2d platformer where the player can press a button, and restart the level, only their previous character will also run the level at the same time, like they are traveling back in time. I know other games have done this before, and the way I have thought of doing it is to make the game character have a set of actions (Idle, Jumping, Walking Left etc.) and then detect changes in those actions and log them into a list along with the game time. So then when I need the character to run the level again on its own, I can just go through the list changing its actions at the right time. Is this the best way to do it? Does anyone have any experience in this? Thanks.

• Excel or Access: how to group several lines in a table and insert contents in columns? ("split column")

  - by Martin

  I have a table containing data of sold products (shown in the example on the left): Columns: Number of the order Product Name Attribute - specifies what is given in the following field "value", e. g. Customer Name or Product Variant Value - is the value of the Attribute Count - is the number of products of this variant sold in the order That means: Product B has 2 variants "c" and "d" Note that in Order 1 Product B was sold in Variant d only, because the letter "N" in field "D4" means "none". Note, that in OrdnerNo 3 Product B was sold only in Variant c, because for Variant d field "D9" is "N"!! This is confusing, but it is the structure of the original data (which I can not change). I need a way to convert the table on the left in a table like that on the right: one line for each product type Order Number Product Name Customer Name Count (number of products sold in this order) Variant - this is the problem, as it has to be filled with the So all rows with the same OrderNo and same product have to be grouped in to one, and I hope it is clear what I need. I tried to do it with Pivot Tables, but that fails, as the Count is always in each line, no matter if it has Value "N" or not and for the products without variants there is only one line for each order, however for products with variants there are several... So how could I create the right table with a VBA macro in MS Excel or maybe there is a trick in MS Access to do it directly or with an SQL query?

• How do you enable view source in ie8 when it gets magically diabled

  - by Tim Meers

  I have multiple computers that all seem to have View Source disabled from the content menu when you right click on a web page. Now I know it's not that the web page is some how disabling it, I'm pretty sure thats not even possible. But alas I have at least 3 machines in my office (not on AD) that have this problem. I have also worked on clients computers that have this same issue. It's down right maddening! I tried to Google for it, but it just shows results from the dawn of IE6 in all of it's "glory" with a bug where if the cache was full it would be disabled. But this is not the case in IE8. Any body have a clue why this is happening, or a fix for it? Maybe a reg setting? Update: So I got a little closer to solving it, but there was still an issue on one computer where it allowed it not is HTTP, but not in HTTPS. One other computer works correctly in both. I Found these two keys missing in the registry: [-HKEY_CURRENT_USER\SOFTWARE\Microsoft\Internet Explorer\View Source Editor] [-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\View Source Editor]

• Exchange 2003 -- Mailbox Management not deleting ALL messages aged 30 days or older...

  - by tcv

  I've recently created a Mailbox Management task within Exchange 2003 that, every night, looks at the contents of the Deleted Items within a particular mailbox and deletes mail that's 30 days or older. The scheduled task ran on its own last night and I have confirmed that messages within the right mailbox and the right folder were, in fact, processed. Many mails were deleted ... but not never email older than 30 days. In fact, the choice seems kinda random. Last night 3/10/2010 was the 30 day watermark. Mails were deleted from 3/10/2010, sure enough, but not all of them. Mails older than 3/10/2010 were deleted as well, but, again, not all of them. The only criteria I have on the management -- aside from the single mailbox and single folder scopes -- is the age criteria. The size criteria is set to Any, meaning I don't care about the size. I care about the age. It's made me wonder where there is some sort of limit on how many mails can be processed? The schedule is set for 12am and 1am every night. Any hints appreciated.

• GPO startup script not copying files

  - by marcwenger

  I created a GPO startup script to execute for computers in a specific AD container. The script takes a file from the AD netlogon share and places it on a directory on the computer. Given the right permissions (ie: myself) can execute the script just fine and the file copies. But it doesn't work on startup - the file does not copy over from the AD server. The startup script should run as localsystem (am I right?). So the question is why do the files not copy on startup? Could it be because of: Is it permissions of the local system user? Reading the registry is problematic on startup? Obtaining files from the AD netlogon folder is problematic on startup? Am I missing it completely? My test machine does have the registry key and local directories as described in the script. I myself have standard user permissions on the test machine. AD server is Windows 2008, test client is Windows XP SP3 (and soon to be Windows 7, which I assume permissions issues will be inevitable) Dim wShell, fso, oraHome, tnsHome, key, srcDir Set wShell = WScript.CreateObject("WScript.Shell") Set fso = CreateObject("Scripting.FileSystemObject") key = "HKLM\Software\Oracle\Oracle_Home" On Error Resume Next orahome = wShell.RegRead(key) If err.Number = 0 Then tnsHome = oraHome + "\" + "network\admin\" srcDir = wShell.ExpandEnvironmentStrings("%logonserver%") + "\netlogon\UpdatedFiles\" fso.CopyFile srcDir + "file1.ext", tnsHome, true End If Side note: To ensure that the script is properly deployed, I purposely put some errors in the script, and on the next startup the error message appeared. So I know the GPO is deployed properly.

• Additional Drivers error installing in Ubuntu 12.04 (wireless internet and software modem)

  - by gabiro

  I've already search for similar problems but they are so different from mine. these are the drivers http://db.tt/qFZlD5JD I'm having problem with this Additional Drivers once I click the Activate button it will start in downloading and installing but after that it will say Installation failed. Then the "Enable Wireless" will not be available. With the Software Modem issue is the same problem with the Broadcom. These drivers are working on Ubuntu 9 and 11 if I'm not mistaken. Only on 12.04 is not working. One more thing these drivers will enable the Huawei E165g E220. I've already tried other solution for the Huawei to activate but all didn't work. After a restart Enable wireless becomes okay, though. To all Ubuntu experts and masters please I'm begging for help. A million Thank You!.

• Single responsibility principle - am I overusing it?

  - by Tarun

  For reference - http://en.wikipedia.org/wiki/Single_responsibility_principle I have a test scenario where in one module of application is responsible for creating ledger entries. There are three basic tasks which could be carried out - View existing ledger entries in table format. Create new ledger entry using create button. Click on a ledger entry in the table (mentioned in first pointer) and view its details in next page. You could nullify a ledger entry in this page. (There are couple more operation/validations in each page but fore sake of brevity I will limit it to these) So I decided to create three different classes - LedgerLandingPage CreateNewLedgerEntryPage ViewLedgerEntryPage These classes offer the services which could be carried out in those pages and Selenium tests use these classes to bring application to a state where I could make certain assertion. When I was having it reviewed with on of my colleague then he was over whelmed and asked me to make one single class for all. Though I yet feel my design is much clean I am doubtful if I am overusing Single Responsibility principle

• apache virtualhost: Auto subdomain with exception

  - by Ineentho

  I've been searching for a way to automatically redirect domains to a specific folder, and fond a good answer here on serverfault: Apache2 VirtualHost auto subdomain. (The accepted answer) So far everything works good, however now I need to add an exception to this. The result I want is this: http://localhost/ --> E:/websites/ http://specialDomain2/ --> E:/websites/ http://normal1.com/ --> E:/websites/normal1.com/ http://normalDomain.com/ --> E:/websites/normal2.com/ I get the expceted result for the two last domains, but the localhost doesn't work. I copied the script from the question aboved, and tried to add something like <VirtualHost *:80> RewriteEngine On RewriteMap lowercase int:tolower # if already rewitten and we have the right path, stop right here RewriteRule ^(E:/websites/[^/]+/.*)$ $1 [L] RewriteRule ^localhost/(.*)$ E:/websites/$1 [L] # <-- Added this row RewriteRule ^(.+) ${lowercase:%{SERVER_NAME}}$1 [C] RewriteRule ^(www\.)?([^/]+)/(.*)$ E:/websites/$2/$3 [L,E=VHOST_ROOT:E:/websites/$2/] </VirtualHost> I thought this would make sense, since I would translate this to if URL = localhost/* Do nothing (because of the [L] flag), and use the default document root specified earlier else continue What's wrong with this? Thanks for any help!

• Why can't I get out of display mirror mode?

  - by Roy Smith

  I've been running Ubuntu (10.04.1 LTS, 64-bit) for a while and just replaced my hardware with a faster machine with an ATI Radeon HD 5700 video card. I've got twin 1920 x 1080 displays. I downloaded the latest driver (ati-driver-installer-10-9-x86.x86_64.run) from the ATI web site and installed that. I've gone through a few rounds of playing with /etc/X11/xorg.conf, and can't get things right. At the moment, it's in display mirroring mode, and I can't figure out how to get it out of mirror mode. If I run Monitor Preferences, there's a "Same image in all monitors" checkbox. If I uncheck that, the little preview window switches to show two monitors. When I click Apply, it asks me to log out and log back in again. When I do that, I'm right back to mirrored mode. What's really weird is that I'm currently running a copy of xorg.conf from a coworker's machine. He's got identical hardware, and his display works fine. So, I'm inclined to think there's something else going on other than the conf file. Any ideas what might be wrong?

• Connection between Asp.Net and Oracle 10g Express Edition

  - by l3gion

  Hello, I'm struggling to find a way to connect my Asp .Net + C# application with my Oracle 10g Express Edition. Here's my scenario, I'm at Mac OS and I have 2 Virtual machines, one for Win 7 (VS 2010 app) and another with a Parallels Virtual Appliance with Oracle 10g Express Edition 1.1. Which provider (Oledb, ODP.NET, etc..) should I use? How to make the connection to the server in C#? Right now I have this: <appSettings> <add key="conn" value="Data Source=10.211.55.11;Persist Security Info=True;User ID=l3gion;Password=l3gion;" /> </appSettings> And at the .cs file: SqlCommand cmd = new SqlCommand("insert_thing", new SqlConnection(ConfigurationManager.AppSettings["conn"])); cmd.CommandType = CommandType.StoredProcedure; *insert_thing is a stored procedure Using this I got this error: A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server) I've searched for some possible solutions. Tried some, including: firewall disabled, allow remote connection at oracle express edition using this cmd line ("EXEC DBMS_XDB.SETLISTENERLOCALACCESS(FALSE);").. The error persists. Can anyone guide me into the right direction? I'm a newbie with this type of things. Thank you for your patience. regards

• Amazon GameCircle Integration

  - by user1095509

  I'm trying to integrate Amazon GameCircle and I have been able to successfully initialize GameCircle in my app, but the problem is when I click on the button that displays achievements, the GameCircle achievement list comes up but it says "You have unlocked 0 of 0 achievements". Same happens with leaderboards i.e there are no leaderboards for this app. I have created a Leaderboard and a few achievements on the online developer portal for Amazon but they don't show for some reason. Can someone help me with this. Any links/resources that help with integrating GameCircle will be appreciated. Thanks.

• Why is this happening with the wine menu?

  - by Patrick

  Some of the items in the Wine menu are given a prefix that is their entire path. The items that don't have the long prefix seem to work fine, but those that do, don't respond to the Properties button or double-click in the menu editor. They take a lot of space, and look ugly, but I can't rename them. I've tried editing their associated files, there doesn't appear to be anything different about them to the ones that are working fine. They weren't always like that - it just happened after an upgrade one day and it's been like that ever since.

• How can I have my VPN connect automatically when the wireless connects?

  - by ams

  I have a working VPN connection using NetworkManager, OpenConnect, and the network-manager-openconnect-gnome package, but I have to start it manually every time I connect to a network, and I have to enter my password manually each time. How can I get it to connect automatically, and remember my password (securely)? I have checked the 'Connect Automatically' box on the Configure VPN page, but this seems to have no effect. I've also got the 'Start connecting automatically' box checked in the pop-up box, and that does avoid the need to press the connect button in that window, but seems to have no part in kicking off the whole process in the first place. There is no option to remember the password in the window, but maybe there's one somewhere else?

• What percent of visitors should click on the next page before you enable prefetching?

  - by Kevin Burke

  Mozilla Firefox and Google Chrome support prefetching via an HTML tag: <!-- in chrome --> <link rel="prerender" href="http://example.org/index.html"> I suppose it is always worthwhile to include this tag if 100% of users on a page click on the "Next Page" button or similar, and never worthwhile to include it if only 2% or 3% of users visit the following page. At what percent of clicks should you turn on prefetching of the next page? 65%? Also, does the calculus change if the current page is HTTP and the next page is HTTPS?

• Customizing Texmaker

  - by Gabriel Furstenheim

  I use LaTeX a lot but I find quite obnoxious all the crappy files it leaves behind when you compile: .aux, .log... Fortunately TeXMaker has the option "clean" that deletes all of these. However, I don't like having to remember to click on it every time I'm going to close a document, ie I'd like a button that both closes a document and cleans all that stuff. Any hint as how to do it? I suppose if I knew how to access the program code I'd be able to do it as I'd just have to put together two options that already exist. Thanks

• Ubuntu 12.10 webapps don't open correctly when using Chromium

  - by Alex

  I have just installed Ubuntu 12.10 completely fresh, the old version of Ubuntu was discarded or overwritten (or whatever you call it). I want to use the Ubuntu webapps with Chromium but I've had several problems. }The first problem is that Chromium won't ask me if I want to install a webapp if I go to a supported site (and I don't already have the webapp installed). The second problem is that when I install the webapp by visiting the site in Firefox, and then I try to open it in Chromium, Ubuntu will open a completely new Chromium icon and window in the Launcher, and the icon will be labeled "Untitled"; also there is no search bar in the new window, only the tab at the top. I've tried using several webapps with Firefox set as the default browser and they work as expected: once the webapp icon is clicked a Firefox window is opened on the Firefox launcher icon, and the window has 'new tab' button and search bar.

• Which CPU for XEN - LAMP testbed - Budget

  - by deploymonkey

  Dear serverfault knowledgeables, im in a decision dilemma right now, which I can't resolve due to lack of hands on experience. I need to build a testbed for basically virtualizing a LAMP application (os'ses not yet decided) including server side calculations. I'll opt for XEN since it seems better supported by cloud hosters at the moment. The hardware is for a proof of concept for a startup doing saas and might be used for closed live alpha/beta later on. After testing, the testbed might be a) deployed as a colocated white box server b) used as workstation Single socket is enough. We want to have ECC memory for reliability, this excludes most of the consumer line at intel. If intel CPU, then threaded cpu (HT) is preferred have at least 16 gig ram If justified by price and reliability is not too bad, a high quality desktop MB instead of a server MB would be worth a try It came down to the opteron 6128 vs. the xeon 5620 for me after a lot of research, but I don't necessarily have to be right. Which CPU is preferrable, concerning TCO (MB price, power requirements 24/7...) , Opteron 6128 or Xeon 5620? Which one offers better performance in real world applications? (Do You have any other suggestions I probably overlooked?) Thank You for Your consideration

• Use external display from boot on Samsung laptop

  - by OhMrBigshot

  I have a Samsung RV511 laptop, and recently my screen broke. I connected an external screen and it works fine, but only after Windows starts. I want to be able to use the external screen right from boot, in order to set the BIOS to boot from DVD, and to then install a different OS and also format the hard drive. Right now I can only use the screen when Windows loads. What I've tried: I've tried opening up the laptop and disconnecting the display to make it only find the external and use the VGA as default -- didn't work. I've tried using the Fn+key combo in BIOS to connect external display - nothing I've been looking around for ways to change boot sequence without entering BIOS, but it doesn't look like it's possible. Possible solutions? A way to change boot sequence without entering BIOS? Someone with the same brand/similar model to help me blindly keystroke the correct arrows/F5/F6 buttons while in BIOS mode to change boot sequence? A way to force the external display to work from boot, through modifying the internal connections (I have no problem taking the laptop apart if needed, please no soldering though), through BIOS or program? Also, if I change boot sequence without accessing external screen, would the Ubuntu 12.1 installation sequence attempt to use the external screen or would I only be able to use it after Linux is installed and running? I'd really appreciate help, I can't afford to fix the screen for a few months from now, and I'd really like to make my computer come back to decent performance! Thanks in advance!

• Migrating from one linux install to another: How to keep the second disk around?

  - by Jim Miller

  I've got a linux box running Fedora 19 that I want to move to CentOS 6.4. Rather than trying to do something fancy with the current disk (which has also accumulated a lot of sludge over the years), I'm going to get a new disk, put CentOS on that, and then move the to-be-preserved bits of stuff from the old disk to the new one. I haven't done this yet, but I presume it should be semi-straightforward -- do the CentOS install on the new disk, mount the old disk on /olddisk or somesuch, and start copying. However, I'm not sure how to handle getting the machine to recognize the new empty disk as the target of the CentOS install (I suppose I can just pull the old disk during the installation), remember that this is the intended boot disk once the install has happened), and tweak /etc/fstab (right?) to set up the old disk on the desired mount point. (Both disks are, or will be, SATA.) I could probably hack it together without losing too much hair or doing too much damage, but could anyone offer some advice that would get/keep me on the right track? Thanks!

• Windows 7/ 12.04 Dual Boot Mess

  - by Ben

  I am certainly new to ubuntu (linux in general)... I added ubuntu 12.04 as a dual boot to a brand new desktop which had win 7 pre-installed. Both work well Then I tried to change the order of the boot menu to make Ubuntu first and Win7 second... I did this from the windows side (it seems that my setup is relying on windows bootloader, which I don't think I need to change) using the built-in startup manager (I think that's what windows calls it- it's in the control panel). I set Ubuntu as first (default if no user input). then... I ACCIDENTALLY ("hmmm...I wonder what this button does?") set the menu timeout to "0" Now, I cannot change the menu timeout (because I cannot get into windows) and without doing so, I cannot select windows as the OS I would like to boot(I cannot get into windows). Any Ideas?
